  • Preschoolers’ genetic, physiological, and behavioral sensitivity factors
           moderate links between parenting stress and child internalizing,
           externalizing, and sleep problems
    • Authors: Molly Davis; Kristel Thomassin, Joanie Bilms, Cynthia Suveg, Anne Shaffer, Steven R.H. Beach
      Abstract: This study examined three potential moderators of the relations between maternal parenting stress and preschoolers’ adjustment problems: a genetic polymorphism—the short allele of the serotonin transporter (5-HTTLPR, ss/sl allele) gene, a physiological indicator—children's baseline respiratory sinus arrhythmia (RSA), and a behavioral indicator—mothers’ reports of children's negative emotionality. A total of 108 mothers (Mage = 30.68 years, SDage = 6.06) reported on their parenting stress as well as their preschoolers’ (Mage = 3.50 years, SDage = 0.51, 61% boys) negative emotionality and internalizing, externalizing, and sleep problems. Results indicated that the genetic sensitivity variable functioned according to a differential susceptibility model; however, the results involving physiological and behavioral sensitivity factors were most consistent with a diathesis-stress framework. Implications for prevention and intervention efforts to counter the effects of parenting stress are discussed.

  • Mild perinatal adversities moderate the association between maternal harsh
           parenting and hair cortisol: Evidence for differential susceptibility
    • Authors: Dafna A. Windhorst; Ralph C.A. Rippe, Viara R. Mileva-Seitz, Frank C. Verhulst, Vincent W.V. Jaddoe, Gerard Noppe, Elisabeth F.C. van Rossum, Erica L.T. van den Akker, Henning Tiemeier, Marinus H. van IJzendoorn, Marian J. Bakermans-Kranenburg
      Abstract: It has been shown that following exposure to mild perinatal adversity, children have greater susceptibility to both the negative and positive aspects of their subsequent environment. In a large population-based cohort study (N = 1,776), we investigated whether mild perinatal adversity moderated the association between maternal harsh parenting and children's hair cortisol levels, a biomarker of chronic stress. Mild perinatal adversity was defined as late preterm birth (gestational age at birth of 34–37 weeks, 6 days) or small for gestational age (birth weight between the 2.5th and 10th percentile for full term gestational age). Harsh parenting was assessed by maternal self-report at 3 years. Children's hair cortisol concentrations were measured from hair samples collected at age 6. There were no significant bivariate associations between mild perinatal adversities and harsh parenting and hair cortisol. However, mild perinatal adversities moderated the association between maternal harsh parenting and hair cortisol levels. Children with mild perinatal adversity had lower cortisol levels if parented more harshly and higher cortisol levels in the absence of harsh parenting than children who did not experience mild perinatal adversity. These results provide further evidence that mild perinatal adversity is a potential marker of differential susceptibility to environmental influences.

  • The effects of stimulus symmetry on hierarchical processing in infancy
    • Authors: Maggie W. Guy; Greg D. Reynolds, Sara M. Mosteller, Kate C. Dixon
      Abstract: The current study investigated the effects of stimulus symmetry on the processing of global and local stimulus properties by 6-month-old short- and long-looking infants through the use of event-related potentials (ERPs). Previous research has shown that individual differences in infant visual attention are related to hierarchical stimulus processing, such that short lookers show a global processing bias, while long lookers demonstrate a local processing bias (Guy, Reynolds, & Zhang, ). Additional research has shown that in comparison with asymmetry, symmetry is associated with more efficient stimulus processing and more accurate memory for stimulus configuration (Attneave, ; Perkins, ). In the current study, we utilized symmetric and asymmetric hierarchical stimuli and predicted that the presence of asymmetry would direct infant attention to the local features of stimuli, leading short lookers to regress to a local processing strategy. Results of the ERP analysis showed that infants familiarized with a symmetric stimulus showed evidence of global processing, while infants familiarized with an asymmetric stimulus did not demonstrate evidence of processing at the global or local level. These findings indicate that short- and long-looking infants, who might otherwise fail to process global stimulus properties due to limited visual scanning, may succeed at global processing when exposed to symmetric stimuli. Furthermore, stimulus symmetry may recruit selective attention toward global properties of visual stimuli, facilitating higher-level cognitive processing in infancy.

  • Context-dependent extinction of an appetitive operant conditioned response
           in infant rats
    • Authors: Estefanía Orellana Barrera; Carlos Arias, Felisa González, Paula Abate
      Abstract: The present study evaluated context-dependent learning under an operant conditioning procedure in infant rats. Preweanling rats were trained in context A during postnatal days (PDs) 16 and 17 to learn an appetitive operant conditioning task, employing milk chocolate as appetitive reinforcer. On PD18 the operant response was extinguished in context A, or in an alternative context B. The change from context A to B between acquisition and extinction did not affect the number of responses during extinction, but slightly modified the shape of the extinction curve. On PD19, a renewal test conducted in context A clearly showed ABA-renewal of the extinguished operant response. These results add to the body of evidence indicating that infants are able to acquire and retain contextual information, and support the notion that extinction during this ontogenetic period involves new learning.

  • Birth order and recalled childhood gender nonconformity in Samoan men and
           fa'afafine
    • Authors: Scott W. Semenyna; Doug P. VanderLaan, Paul L. Vasey
      Abstract: Having a greater than average number of older biological brothers is a robust correlate of male androphilia (i.e., sexual attraction and arousal to adult males). Previous investigations have sought to understand whether this fraternal birth order (FBO) effect is also systematically related to recalled indicators of childhood gender nonconformity (CGN). However, these investigations have relied on data from low-fertility Western populations in which expressions of femininity in male children are routinely stigmatized and consequently, suppressed. The present study examined the FBO effect (among other sibship characteristics) and recalled indicators of CGN in Samoa, a high-fertility population, whose members are relatively tolerant of male femininity. Indeed, Samoans identify feminine androphilic males as belonging to an alternative gender category, known locally as fa'afafine. The present study compared the sibship characteristics of 231 fa'afafine and 231 opposite-sex attracted men from Samoa, as well as how these characteristics related to recalled CGN. Results replicated the well-established FBO effect for predicting male sexual orientation, with each older brother increasing the odds of being androphilic by 21%. However, no relationship was found between the number of older brothers (or other siblings) a participant had and their recalled CGN. Although fa'afafine reported significantly more CGN than Samoan men, CGN did not mediate the FBO effect, nor did the FBO effect and CGN interact to predict male sexual orientation. These findings are consistent with previous studies suggesting that the FBO effect is associated with male sexual orientation, but not childhood female-typical gender expression among androphilic males.

  • Parasympathetic reactivity and disruptive behavior problems in young
           children during interactions with their mothers and other adults: A
           preliminary investigation
    • Authors: Christine E. Cooper-Vince; Mariah DeSerisy, Danielle Cornacchio, Amanda Sanchez, Katie A. McLaughlin, Jonathan S. Comer
      Abstract: Parasympathetic nervous system influences on cardiac functions—commonly indexed via respiratory sinus arrhythmia (RSA)—are central to self-regulation. RSA suppression during challenging emotional and cognitive tasks is often associated with better emotional and behavioral functioning in preschoolers. However, the links between RSA suppression and child behavior across various challenging interpersonal contexts remains unclear. The present study experimentally evaluated the relationship between child RSA reactivity to adult (mother vs. study staff) direction and disruptive behavior problems in children ages 3–8 with varying levels of disruptive behavior problems (N = 43). Reduced RSA suppression in the context of mothers’ play-based direction was associated with more severe child behavior problems. In contrast, RSA suppression in the context of staff play-based direction was not associated with behavior problems. Findings suggest that the association between RSA suppression and child behavior problems may vary by social context (i.e., mother vs. other adult direction-givers). Findings are discussed in regard to RSA as an indicator of autonomic self-regulation that has relevance to child disruptive behavior problems.

  • Lipids in maternal diet influence yolk hormone levels and post-hatch
           neophobia in the domestic chick

      Abstract: We assessed whether the ratio of dietary n-6/n-3 polyunsaturated fatty acids (PUFA) during egg formation engenders transgenerational maternal effects in domestic chicks. We analyzed yolk lipid and hormone concentrations, and HPA-axis activity in hens fed a control diet (high n-6/n-3 ratio) or a diet enriched in n-3 PUFAs (low n-6/n-3 ratio) for 6 consecutive weeks. Their chicks were tested for neophobia during the first week of life. We found higher corticosterone metabolites in droppings of hens fed the diet enriched in n-3 and significantly higher concentrations of yolk progesterone, androstenedione, and estradiol in their eggs compared to controls. Chicks of hens fed the n-3 enriched diet showed a lower body mass at hatch than controls and expressed higher neophobia when exposed to a novel object. These results add support to the hypothesis that the nutritional state of female birds produces variation in yolk hormone levels and engender maternal effects.

  • FKBP5 genotype and early life stress exposure predict neurobehavioral
           outcomes for preterm infants
    • Authors: Amy L. D'Agata; Stephen Walsh, Dorothy Vittner, Xiaomei Cong, Jacqueline M. McGrath, Erin E. Young
      Abstract: PROBLEMThis study evaluated the relationship between stressful early life neonatal intensive care unit (NICU) experiences, genetic variation of a stress response-associated gene (FKBP5), and neurobehavioral outcomes.METHODThe impact of genetic variation and stress experience on neurobehavioral outcomes was examined for 41 preterm infants. Statistical analyses explored the main effects of FKBP5 genotype and NICU stress experience, as well as their interaction on infant neurobehavioral development prior to discharge.RESULTSStatistical analyses demonstrated a relationship between both FKPB5 genotype and stress related to NICU care that were independently associated with neurobehavioral outcomes; indicating a main effect of genotype and a main effect of stress on neurodevelopment. Additionally, we found an interaction between the minor allele genotype and NICU stress potentially associated with less favorable developmental progress at discharge.IMPLICATIONSEvidence of genetic and environmental risk factors for neurodevelopmental impairment suggests the need for improved evidence-based practice initiatives to protect those most vulnerable to the combination of genetic susceptibility to stress and medical fragility.

  • Context-dependent individual differences in playfulness in male rats
    • Authors: Jessica F. Lampe; Oliver Burman, Hanno Würbel, Luca Melotti
      Abstract: Play has been proposed as an indicator of positive emotions and welfare in higher vertebrates. This study investigated playfulness in male rats by exploring its consistency across motivational states (with/without prior short social isolation) and two age points at early and late adolescence. Twenty-four male Lister Hooded rats housed in cages of four underwent two play tests: conspecific Play-in-Pairs and Tickling by the experimenter, which were compared with play in the home cage and basal anxiety levels. Play-in-Pairs measures were consistent across age and motivational states, and were independent from anxiety. Positively valenced vocalizations in the Tickling test were also consistent across age, yet were negatively related to anxiety. Play-in-Pairs and Tickling play contexts, as well as social and solitary play types, were unrelated. Therefore, this study supports the existence of consistent individual differences in playfulness in rats, and suggests that different play contexts and types represent motivationally distinct systems.

  • Dyadic flexibility mediates the relation between parent conflict and
           infants’ vagal reactivity during the Face-to-Face Still-Face
    • Authors: Alex Busuito; Ginger A. Moore
      Abstract: Parent conflict is related to attenuated infant vagal reactivity, suggesting less effective regulation. Because infants’ self-regulation develops in the context of coregulation, the current study examined a novel measure, flexibility, purported to reflect dyadic reorganization in response to contextual demands. Flexibility was expected to mediate the relation between greater conflict and lesser vagal reactivity during the reunion episode of the Face-to-Face Still-Face (FFSF). Six-month-old infants’ and their mothers’ (N = 53) affective behaviors were observed during the FFSF and heart rate data were collected for infants. Flexibility was computed using state-space analysis of dyadic behaviors and measured variability in and movement among dyadic states. Conflict was related to lesser infant vagal reactivity in the reunion through lower flexibility, suggesting less effective recovery from social stress. Flexibility may capture aspects of coregulation affected by environmental stress and may be one mechanism by which conflict contributes to developing vagal regulation.

  • Biological embedding of perinatal social relationships in infant stress
           reactivity
    • Authors: Jenna C. Thomas; Nicole Letourneau, Crystal I. Bryce, Tavis S. Campbell, Gerald F. Giesbrecht,
      Abstract: Whereas significant advances have been made in understanding how exposure to early adversity “gets under the skin” of children to result in long term changes in developmental outcomes, the processes by which positive social relationships become biologically embedded remain poorly understood. The aim of this study was to understand the pathways by which maternal and infant social environments become biologically embedded in infant cortisol reactivity. Two hundred seventy-two pregnant women and their infants were prospectively assessed during pregnancy and at 6 months postpartum. In serial mediation analyses, higher perceived social support from partners during pregnancy was associated with lower infant cortisol reactivity or larger decreases in cortisol in response to a stressor at 6 months of age via lower self-reported prenatal maternal depression and higher mother–infant interaction quality. The findings add to our understanding of how perinatal social relationships become biologically embedded in child development.

           experienced visual deprivation during infancy
    • Authors: Sidney J. Segalowitz; Avital Sternin, Terri L. Lewis, Jane Dywan, Daphne Maurer
      Abstract: We examined the role of early visual input in visual system development by testing adults who had been born with dense bilateral cataracts that blocked all patterned visual input during infancy until the cataractous lenses were removed surgically and the eyes fitted with compensatory contact lenses. Patients viewed checkerboards and textures to explore early processing regions (V1, V2), Glass patterns to examine global form processing (V4), and moving stimuli to explore global motion processing (V5). Patients' ERPs differed from those of controls in that (1) the V1 component was much smaller for all but the simplest stimuli and (2) extrastriate components did not differentiate amongst texture stimuli, Glass patterns, or motion stimuli. The results indicate that early visual deprivation contributes to permanent abnormalities at early and mid levels of visual processing, consistent with enduring behavioral deficits in the ability to process complex textures, global form, and global motion.

  • The development of repetitive motor behaviors in deer mice: Effects of
           environmental enrichment, repeated testing, and differential mediation by
           indirect basal ganglia pathway activation
    • Authors: Allison R. Bechard; Nikolay Bliznyuk, Mark H. Lewis
      Abstract: Little is known about the mechanisms mediating the development of repetitive behaviors in human or animals. Deer mice reared with environmental enrichment (EE) exhibit fewer repetitive behaviors and greater indirect basal ganglia pathway activation as adults than those reared in standard cages. The developmental progression of these behavioral and neural circuitry changes has not been characterized. We assessed the development of repetitive behavior in deer mice using both a longitudinal and cohort design. Repeated testing negated the expected effect of EE, but cohort analyses showed that progression of repetitive behavior was arrested after 1 week of EE and differed significantly from controls after 3 weeks. Moreover, EE reductions in repetitive behavior were associated with increasing activation of indirect pathway nuclei in males across adolescence, but not females. These findings provide the first assessment of developmental trajectories within EE and support indirect pathway mediation of repetitive behavior in male deer mice.

  • Chronic social instability in adult female rats alters social behavior,
           maternal aggression and offspring development
    • Authors: Florent Pittet; Jessica A. Babb, Lindsay Carini, Benjamin C. Nephew
      Abstract: We investigated the consequences of chronic social instability (CSI) during adulthood on social and maternal behavior in females and social behavior of their offspring in a rat model. CSI consisted of changing the social partners of adult females every 2–3 days for 28 days, 2 weeks prior to mating. Females exposed to CSI behaved less aggressively and more pro-socially towards unfamiliar female intruders. Maternal care was not affected by CSI in a standard testing environment, but maternal behavior of CSI females was less disrupted by a male intruder. CSI females were quicker to attack prey and did not differ from control females in their saccharin consumption indicating, respectively, no stress-induced sensory-motor or reward system impairments. Offspring of CSI females exhibited slower growth and expressed more anxiety in social encounters. This study demonstrates continued adult vulnerability to social challenges with an impact specific to social situations for mothers and offspring.

  • Behavioral development in embryonic and early juvenile cuttlefish (Sepia
           officinalis)
    • Authors: Caitlin E. O'Brien; Nawel Mezrai, Anne-Sophie Darmaillacq, Ludovic Dickel
      Pages: 145 - 160
      Abstract: Though a mollusc, the cuttlefish Sepia officinalis possesses a sophisticated brain, advanced sensory systems, and a large behavioral repertoire. Cuttlefish provide a unique perspective on animal behavior due to their phylogenic distance from more traditional (vertebrate) models. S. officinalis is well-suited to addressing questions of behavioral ontogeny. As embryos, they can perceive and learn from their environment and experience no direct parental care. A marked progression in learning and behavior is observed during late embryonic and early juvenile development. This improvement is concomitant with expansion and maturation of the vertical lobe, the cephalopod analog of the mammalian hippocampus. This review synthesizes existing knowledge regarding embryonic and juvenile development in this species in an effort to better understand cuttlefish behavior and animal behavior in general. It will serve as a guide to future researchers and encourage greater awareness of the utility of this species to behavioral science.

  • Neuroendocrine factors distinguish juvenile psychopathy variants
    • Authors: Eva R. Kimonis; Natalie Goulter, David J. Hawes, Rhonda R. Wilbur, Maureen W. Groer
      Pages: 161 - 173
      Abstract: The characteristic pattern of emotional hypo-reactivity observed in primary psychopathy is not evident in secondary psychopathy, which is thought to originate from childhood adversity and co-occurring anxiety. The main aim of this study was to test whether salivary afternoon cortisol, Dehydroepiandrosterone (DHEA), and cortisol-to-DHEA concentrations, which at high levels indicate risk for chronic stress and poor mental health, distinguished secondary from primary variants of callous-unemotional (CU) traits—the affective component of psychopathy. This aim was achieved by first identifying psychopathy variants using latent profile analysis of CU, anxiety, and aggression scores among 232 incarcerated adolescent boys (M age = 16.75). Based on a subset with neuroendocrine data (n = 201), aggressive secondary CU variants had lower afternoon DHEA concentrations and higher cortisol-to-DHEA ratios and comorbid psychopathology compared with all other groups. In contrast, two primary CU variants (aggressive and non-aggressive types) emerged with profiles characterized by low to average psychopathology and high DHEA levels. Findings contribute to a growing literature base suggesting that biomarkers may distinguish youth on separable developmental pathways to psychopathy.

  • Do different data analytic approaches generate discrepant findings when
           measuring mother–infant HPA axis attunement'
    • Authors: Nicola K. Bernard; Deborah A. Kashy, Alytia A. Levendosky, G. Anne Bogat, Joseph S. Lonstein
      Pages: 174 - 184
      Abstract: Attunement between mothers and infants in their hypothalamic-pituitary-adrenal (HPA) axis responsiveness to acute stressors is thought to benefit the child's emerging physiological and behavioral self-regulation, as well as their socioemotional development. However, there is no universally accepted definition of attunement in the literature, which appears to have resulted in inconsistent statistical analyses for determining its presence or absence, and contributed to discrepant results. We used a series of data analytic approaches, some previously used in the attunement literature and others not, to evaluate the attunement between 182 women and their 1-year-old infants in their HPA axis responsivity to acute stress. Cortisol was measured in saliva samples taken from mothers and infants before and twice after a naturalistic laboratory stressor (infant arm restraint). The results of the data analytic approaches were mixed, with some analyses suggesting attunement while others did not. The strengths and weaknesses of each statistical approach are discussed, and an analysis using a cross-lagged model that considered both time and interactions between mother and infant appeared the most appropriate. Greater consensus in the field about the conceptualization and analysis of physiological attunement would be valuable in order to advance our understanding of this phenomenon.

  • The “when” and the “where” of single-trial allocentric spatial
           memory performance in young children: Insights into the development of
           episodic memory
    • Authors: Farfalla Ribordy Lambert; Pierre Lavenex, Pamela Banta Lavenex
      Pages: 185 - 196
      Abstract: Allocentric spatial memory, “where” with respect to the surrounding environment, is one of the three fundamental components of episodic memory: what, where, when. Whereas basic allocentric spatial memory abilities are reliably observed in children after 2 years of age, coinciding with the offset of infantile amnesia, the resolution of allocentric spatial memory acquired over repeated trials improves from 2 to 4 years of age. Here, we first show that single-trial allocentric spatial memory performance improves in children from 3.5 to 7 years of age, during the typical period of childhood amnesia. Second, we show that large individual variation exists in children's performance at this age. Third, and most importantly, we show that improvements in single-trial allocentric spatial memory performance are due to an increasing ability to spatially and temporally separate locations and events. Such improvements in spatial and temporal processing abilities may contribute to the gradual offset of childhood amnesia.

  • Toddler parasympathetic regulation and fear: Links to maternal appraisal
           and behavior
    • Authors: Sunghye Cho; Kristin A. Buss
      Pages: 197 - 208
      Abstract: There is a growing recognition that parental socialization influences interact with young children's emerging capacity for physiological regulation and shape children's developmental trajectories. Nevertheless, the transactional processes linking parental socialization and physiological regulatory processes remain not well understood, particularly for fear-prone toddlers. To address this gap in the literature, the present study investigated the biopsychosocial processes that underlie toddlers’ fear regulation by examining the relations among toddler parasympathetic regulation, maternal appraisal, and parenting behaviors. Participants included 124 mothers and their toddlers (Mage = 24.43 months), who participated in a longitudinal study of temperament and socio-emotional development. Toddlers’ parasympathetic reactivity was found to moderate the links between maternal anticipatory appraisal of child fearfulness and (a) maternal provision of physical comfort and (b) preschool-age child inhibition. Additionally, maternal comforting behaviors during the low-threat task predicted preschool-age separation distress, specifically for toddlers demonstrating a low baseline RSA.

  • Respiratory sinus arrhythmia moderates the impact of maternal prenatal
           anxiety on infant negative affectivity

      Abstract: Maternal prenatal anxiety is associated with infants’ temperamental negative affectivity (NA), but it is unclear to what extent children vary in their susceptibility to prenatal influences. We tested a hypothesis that infants’ respiratory sinus arrhythmia (RSA), an index of parasympathetic vagal tone and a potential marker of differential susceptibility to environmental influences, moderates the effects of maternal prenatal anxiety on the development of infant NA. Prenatal anxiety was assessed during the last trimester of pregnancy in a low-risk community sample. Infant NA, baseline RSA, and maternal postnatal anxiety were assessed at 8–10 months of infant age. Regression analyses were performed to predict infant NA on the basis of prenatal anxiety, infant baseline RSA, and their interaction (N = 173). Maternal prenatal anxiety and infant RSA interactively predicted infant NA at 8–10 months. Among infants with high RSA, a significant positive association between prenatal anxiety and infant NA was observed, whereas prenatal anxiety did not predict infant NA among infants with low RSA. Vagal tone, as indexed by baseline RSA, may provide a promising marker of differential susceptibility to the long-term effects of varying intrauterine conditions.

  • Cortisol stress responses and children's behavioral functioning at school
    • Authors: Sterre S.H. Simons; Antonius H.N. Cillessen, Carolina de Weerth
      Pages: 217 - 224
      Abstract: The present study investigated whether cortisol stress responses of 6-year-olds were associated with their behavioral functioning at school. Additionally, the moderating role of stress in the family environment was examined. To this end, 149 healthy children (Mage = 6.09 years; 70 girls) participated in an age-appropriate innovative social evaluative stress test. Saliva cortisol samples were collected six times during the stress test to calculate two indices of the cortisol stress response: cortisol stress reactivity and total stress cortisol. Teachers assessed children's internalizing, externalizing, and prosocial behaviors. Stress in the family environment was operationalized as maternally reported parenting stress. Results indicated a significant increase in cortisol concentrations in response to the stressor. No significant associations were found between cortisol stress responses and behavioral functioning at school and there was no evidence for moderation by maternal parenting stress. Potential theoretical and methodological explanations for these results are discussed.

           differences
    • Authors: Airín D. Martínez; Lillian Ruelas, Douglas A. Granger
      Pages: 225 - 234
      Abstract: Uric acid (UA) is the end product of the metabolic breakdown of purine nucleotides. Recent studies have measured UA in saliva in relation to obesity and chronic disease risk. Given the increasing prevalence of metabolic syndrome among Latino youth, we examined gender and age differences in salivary uric acid (sUA) and weight in a sample of Mexican-origin children (n = 65, 2 months to 18 years, 49% female) and adults (n = 46, 19–58 years, 72% female). We measured weight, height, waist, and hip circumference and collected saliva samples (later assayed for sUA). Structural equation models estimated the relationship between age, developmental stage, and weight outcomes in relation to sUA levels between genders, while controlling for race. Results demonstrate that increased sUA levels were related to higher BMI percentiles in females of all ages (β = 0.43, p

  • Maternal deprivation alters expression of neural maturation gene tbr1 in
           the amygdala paralaminar nucleus in infant female macaques
    • Authors: Danielle M. de Campo; Judy L. Cameron, Joseph M. Miano, David A. Lewis, Karoly Mirnics, Julie L. Fudge
      Pages: 235 - 249
      Abstract: Early parental loss is associated with social–emotional dysregulation and amygdala physiologic changes. Previously, we examined whole amygdala gene expression in infant monkeys exposed to early maternal deprivation. Here, we focus on an amygdala region with immature neurons at birth: the paralaminar nucleus (PL). We hypothesized that 1) the normal infant PL is enriched in a subset of neural maturation (NM) genes compared to a nearby amygdala subregion; and 2) maternal deprivation would downregulate expression of NM transcripts (mRNA). mRNAs for bcl2, doublecortin, neuroD1, and tbr1—genes expressed in post-mitotic neurons—were enriched in the normal PL. Maternal deprivation at either 1 week or 1 month of age resulted in PL-specific downregulation of tbr1—a transcription factor necessary for directing neuroblasts to a glutamatergic phenotype. tbr1 expression also correlated with typical social behaviors. We conclude that maternal deprivation influences glutamatergic neuronal development in the PL, possibly influencing circuits mediating social learning.

  • Neural mechanisms of attention become more specialised during infancy:
           Insights from combined eye tracking and EEG
    • Authors: Louisa Kulke; Janette Atkinson, Oliver Braddick
      Pages: 250 - 260
      Abstract: The Fixation Shift Paradigm (FSP) measures infants’ ability to shift gaze from a central fixation stimulus to a peripheral target (e.g. Hood & Atkinson, 1993: Infant Behavior and Development, 16(4), 405–422). Cortical maturation has been suggested as crucial for the developing ability to shift attention. This study investigated the development of neural mechanisms by combining EEG with simultaneous eye tracking during FSP testing, in typically developing infants aged between 1 and 8 months. The most prominent neural response was a frontal positivity which occurred only in the hemisphere contralateral to the target in the youngest infants but became more ipsilateral with age. This changing lateralisation was associated with improving ability to shift attention (decreasing saccade latencies and fewer ‘sticky fixations’—failures to disengage attention from the central target). These findings suggest that the lateralisation of neural responses develops during infancy, possibly due to developing intracortical connections, allowing infants to shift attention more efficiently.RESEARCH HIGHLIGHTSSuccessful use of combined simultaneous remote eye tracking and EEG to measure infant attention shifts.Neural responses involved in attention shifts change in the first year of life.The lateralisation of EEG responses changes with age in the first year of life.Frontal cortex is involved in attention shifts from around 2 months of age.

  • Infant respiratory sinus arrhythmia and maternal depressive symptoms
           predict toddler sleep problems
    • Authors: Noa Gueron-Sela; Cathi B. Propper, Nicholas J. Wagner, Marie Camerota, Kristin P. Tully, Ginger A. Moore
      Pages: 261 - 267
      Abstract: This study examined the direct and interactive effects of infants’ respiratory sinus arrhythmia (RSA) and maternal depressive symptoms (MDS) during the first 6 months of life in the prediction of children's sleep problems at age 18 months. Participants included 156 children and their mothers who were followed from 3 to 18 months of age. At ages 3 and 6 months, infants’ cardiac activity was recorded at rest and during the still-face paradigm, a mother–child social challenge task, and estimates of infant baseline RSA (RSAB) and RSA withdrawal (RSAW) were calculated. Mothers reported about their depressive symptoms at 3, 6, and 18 months, and about infants’ sleep problems at age 18 months. Less RSAW and higher levels of MDS predicted more sleep problems at age 18 months. Additionally, RSAB moderated the link between MDS and children's sleep problems such that MDS were related to more sleep problems only for infants with high levels of RSAB. Results illustrate the importance of RSA as both a direct predictor and a moderator of maternal influences in the prediction of early sleep problems.

  • Running during adolescence rescues a maternal separation-induced memory
           impairment in female mice: Potential role of differential exon-specific
           BDNF expression
    • Authors: Luis Eduardo Wearick-Silva; Paul Marshall, Thiago Wendt Viola, Anderson Centeno-Silva, Lucas Araújo de Azeredo, Rodrigo Orso, Xiang Li, Márcio V. Donadio, Timothy W. Bredy, Rodrigo Grassi-Oliveira
      Pages: 268 - 274
      Abstract: Exposure to early life stress has been associated with memory impairments related to changes in brain-derived neurotrophic factor (BDNF) signaling. However, the potential impact of physical exercise to reverse these effects of maternal separation has been under investigated. Mice were subjected to maternal separation during the first 2 weeks of life and then exposed to a 3-week running protocol during adolescence. The spontaneous object recognition task was performed during adolescence followed by analysis of hippocampal expression of exons I, IV, and IX of the BDNF gene. As expected, maternal separation impaired recognition memory and this effect was reversed by exercise. In addition, running increased BDNF exon I expression, but decreased expression of BDNF exon IV in all groups, while exon IX expression increased only in MS animals exposed to exercise. Our data suggest that memory deficits can be attenuated by exercise and specific transcripts of the BDNF gene are dynamically regulated following both MS and exercise.
