Current Tobacco-Smoking and Neural Responses to Infant Cues in Mothers

Objective. Smoking has a detrimental impact on maternal physical health and exposes children to secondhand smoke, but the extent to which it affects maternal brain and behavior is not well-known and may have implications for parent and child development. We examined how current smoking status might relate to maternal neural responses to infant cues using event-related potentials. Design. Current smoking (n = 35) and non-smoking (n = 35) mothers viewed photographs of emotional infant faces while electroencephalography was simultaneously recorded. Results. The latency of the face-specific N170 event-related potential component was delayed in smoking mothers compared to non-smoking mothers, and the P300 was differentiated by smoking status. Conclusions. Postpartum smoking is associated with event-related potential measures that may reflect modulation of infant face perception in motherhood.     

The Past is Present: Responses to Infant Crying Among Mothers High in Attachment Anxiety

SYNOPSIS

This commentary explores potential mechanisms underlying the links between mothers’ attachment anxiety and levels of salivary alpha amylase in response to infant crying across levels of spouse support. The commentary argues that the current design cannot disentangle different explanations for the effects – whether they reflect general stress reactivity patterns or patterns occurring specifically in response to infant distress – and offers suggestions for ways in which to explore putative explanations in future studies. Understanding mechanisms is essential to identify risk factors for insensitive parenting.

Causal Learning Across Culture and Socioeconomic Status

Extensive research has explored the ability of young children to learn about the causal structure of the world from patterns of evidence. These studies, however, have been conducted with middle-class samples from North America and Europe. In the present study, low-income Peruvian 4- and 5-year-olds and adults, low-income U.S. 4- and 5-year-olds in Head Start programs, and middle-class children from the United States participated in a causal learning task (N = 435). Consistent with previous studies, children learned both specific causal relations and more abstract causal principles across culture and socioeconomic status (SES). The Peruvian children and adults generally performed like middle-class U.S. children and adults, but the low-SES U.S. children showed some differences.     

动、静态表情对面孔性别判断的影响

本研究通过选取30名大学生对动、静态呈现的面孔表情图片进行性别判断,研究动、静态呈现的面孔表情对面孔性别加工的影响。研究发现：反应时结果出现了图片性别和图片情绪的交互作用。男性面孔在不同情绪下的反应时长短依次为：积极＞中性＞消极;女性面孔在不同情绪下的反应时长短依次为：积极＞消极＞中性。正确率结果中也出现了图片性别和图片情绪的交互作用。判断消极情绪时的男性面孔正确率比中性和积极情绪时的正确率高;判断中性情绪时的女性面孔正确率比积极和消极情绪时的正确率高。该结果说明：面孔表情信息影响性别信息的加工,且因男女性别信息而效果不同。     

Prenatal and Postnatal Diagnosis of Infant Disability: Breaking the News to Mothers

The birth of an infant with a disability is often perceived as the loss of a “perfect” baby and is typically an unanticipated event for the mother and family. Mothers may experience self-blame for the disability; therefore, sensitive communication is crucial. A private setting is recommended, with a minimum of health-care professionals in attendance when the diagnosis is revealed. The perinatal educator can guide the mother through the early emotional phases of processing and accepting the new information by offering support and incorporating timely information and interventions. The perinatal educator can also inform and prepare other expectant couples in the childbirth class and encourage them to support the mother and father in celebrating the forthcoming birth. The objective of nursing care for a mother whose infant is newly diagnosed with a disability is to facilitate a positive outcome for her and to promote optimal infant bonding. In all communication and information, replacing the term “disabled infant” with “infant with a disability” is emphasized in order to recognize the infant first and the disability second.     

Infants' Responses to Facial and Vocal Emotional Signals in a Social Referencing Paradigm

The independent effects of facial and vocal emotional signals and of positive and negative signals on infant behavior were investigated in a novel toy social referencing paradigm. 90 12-month-old infants and their mothers were assigned to an expression condition (neutral, happy, or fear) nested within a modality condition (face-only or voice-only). Each infant participated in 3 trials: a baseline trial, an expression trial, and a final positive trial. We found that fearful vocal emotional signals, when presented without facial signals, were sufficient to elicit appropriate behavior regulation. Infants in the fear-voice condition looked at their mothers longer, showed less toy proximity, and tended to show more negative affect than infants in the neutral-voice condition. Happy vocal signals did not elicit differential responding. The infants' sex was a factor in the few effects that were found for infants' responses to facial emotional signals.     

Affective Influences on Startle in Five-Month-Old Infants: Reactions to Facial Expressions of Emotion

Convergent methodologies from studies of fear-potentiated startle in animals and studies of affective modulation of reflex blinks in humans were adapted in order to investigate infants' sensitivity to affective information conveyed by facial expressions of emotion. While 5-month-old infants viewed photographic slides of faces posed in happy, neutral, or angry expressions, a brief acoustic noise burst was presented to elicit the blink component of human startle. Blink size was augmented during the viewing of angry expressions and reduced during happy expressions. Infants did not show marked changes in behavioral reactions to the positive, neutral, and negative slides, although motor activity was slightly reduced during negative slides. Results suggest that, by 5 months, infants react to affective information conveyed by unfamiliar human faces. Potential mechanisms mediating the influence of affective stimuli on reflex excitability are considered.     

Maternal Responses to Infant Distress: Linkages Between Specific Emotions and Neurophysiological Processes

Objective. The goals of the current article were to test the presence of an association between mothers’ neural activity (measured by frontal cortical alpha asymmetry) and their specific emotions (measured by observed facial expressions) in response to infant distress and the moderation of this relation by mothers’ appraisal processes (measured by sense of parenting efficacy). Design. Mothers of 5- to 8-month-olds (n = 26) watched videos of their own infants expressing distress while their brain activity was recorded via electroencephalogram and their facial expressions were videotaped for later microcoding. Mothers also completed a questionnaire measure of parenting efficacy. Results. Greater neurophysiological withdrawal in response to infant distress videos, indexed by frontal alpha asymmetry, was associated with longer sad and tense expressions in mothers with average or below average parenting efficacy, but not in those with above average efficacy. Conclusions. Previous research showing that patterns of parents’ brain activity in response to child stimuli are associated with parenting behavior often interpret results in relation to parental emotion, but rarely measure specific concurrent emotions. The current study helps fill this gap in the literature by showing that maternal neurophysiological withdrawal (together with parenting efficacy) was associated with simultaneously measured facial expressions of negative emotion in response to infant distress stimuli.     

A Glimpse into the Minds of Mothers: The Default Mode Network and Responsiveness to Infant Cries

SYNOPSIS

The authors comment on a paper reporting differences between mothers and non-mothers in neural responses to infant cries and other emotive sounds while engaging in self- or goal-oriented tasks. The value of examining deactivation of the default mode network (DMN) as a means of understanding differential attention patterns in both typical and atypical populations is discussed, as is the generalizability of the experimental paradigm to ecologically relevant contexts. The role of an individual’s age, parental status, and experience in shaping responses to infant crying is considered, and future avenues of research are suggested. An argument is made for coupling neuroimaging techniques with behavioral assays to better understand the determinants of maternal behavior.

Generalized Discrimination of Positive Facial Expressions by Seven- and Ten-Month-Old Infants

The ability of 7- and 10-month-old infants to generalize their discrimination of facial expressions lacking featural consistency was investigated in a series of 4 experiments. Infants were habituated to models posing either prototypically positive displays (e.g., happy expressions) or positive expression blends (e.g., mock surprise). They were then tested for their ability to recognize a positive expression on the face of a novel model and to discriminate positive and negative facial expressions. Only in Experiment 1, in which infants were familiarized to a mix of happy and surprised facial expressions, did 10-month-olds demonstrate generalized discrimination of positive affect. When positive blends or happy expressions alone served as familiarization stimuli, both 7- and 10-month-old infants failed to dishabituate to a change in affective tone. 7-month-olds, in particular, showed consistent recovery of looking to the introduction of novel models. The pattern of results suggests that it is not until sometime after 7 months of age that dependence on the presence of expression-specific features for affect recognition and discrimination diminishes. By 10 months of age, however, infants are beginning to recognize the affective similarity of familiar positive facial expressions.     

Responses to Interpersonal Stress: Normative Changes Across Childhood and the Impact of Peer Victimization

This research examined the development of stress responses across second to sixth grades and whether exposure to peer victimization alters stress response trajectories. Youth (338 girls; 298 boys; M_age = 7.97 years, SD = .37) reported on stress responses; teachers and youth reported on peer victimization. Latent growth curve modeling revealed an increase in effortful engagement responses and a decrease in disengagement and involuntary engagement responses during this period. Peer victimization disrupted these normative trajectories, resulting in less effortful engagement and more effortful disengagement and involuntary stress responses in early adolescence. These findings suggest that early peer victimization sensitizes youth to stress by interfering with the development of effective coping and fostering maladaptive stress responses.

Psychosocial Attributes and Life Experiences of Disadvantaged Minority Mothers: Age and Ethnic Variations

This study examined age and ethnic differences in psychosocial factors among hispanic (n = 210) and black (n = 73) low-income mothers within 2 days after delivery. The sample included 45 black and 99 hispanic adolescents (less than 19 years) and 139 adult controls (greater than or equal to 20 years) giving birth on the service ward at a large metropolitan hospital, excluding mothers and infants with high parity or adverse perinatal conditions. Multivariate and univariate analyses, with parity covaried, revealed age effects including earlier menarche, more school grade retention, and more perceived social support among teens. No age differences were found in child-rearing attitudes, self-esteem, or depressive symptoms. Black mothers reported more social support, higher self-esteem, and less strict child-rearing attitudes than hispanics. Analyses within the hispanic sample revealed Dominican/Puerto Rican group differences in measures of family structure and child-rearing attitudes, but only small differences in social support. Ethnocultural differences between blacks and hispanics and between the two hispanic subgroups are considered in relation to the process of acculturation.     

Developmental Change in Infant Categorization: The Perception of Correlations among Facial Features

Previous studies indicated that the ability to detect correlations among attributes emerges between 7 and 10 months of age. In the present study, the generality of this developmental transition was examined. Using an infant-control habituation procedure, 48 7- and 10-month-old infants were tested for the perception of correlations among basic facial features. The developmental effects were replicated. Only the 10-month-old infants demonstrated their sensitivity to the pattern of correlation by generalizing to a novel face that preserved the experienced pattern of correlation, while showing increased attention to a face in which the pattern of correlation was violated. 7-month-old infants generalized to both test stimuli containing familiar features, regardless of the status of the correlation. Implications for face perception and the processing of categorical information are discussed.     

The Role of Socioeconomic Status in SAT–Freshman Grade Relationships Across Gender and Racial Subgroups

Recent research has shown that admissions tests retain the vast majority of their predictive power after controlling for socioeconomic status (SES), and that SES provides only a slight increment over SAT and high school grades (high school grade point average [HSGPA]) in predicting academic performance. To address the possibility that these overall analyses obscure differences by race/ethnicity or gender, we examine the role of SES in the test‒grade relationship for men and women as well as for various racial/ethnic subgroups within the United States. For each subgroup, the test‒grade relationship is only slightly diminished when controlling for SES. Further, SES is a substantially less powerful predictor of academic performance than both SAT and HSGPA. Among the indicators of SES (i.e., father's education, mother's education, and parental income), father's education appears to be strongest predictor of freshman grades across subgroups, with the exception of the Asian subgroup. In general, SES appears to behave similarly across subgroups in the prediction of freshman grades with SAT scores and HSGPA.     

Infant Crying and Adults'' Anticipated Caregiving Responses: Acoustic and Contextual Influences

These studies assessed adults' latencies to signal that they would respond to infant crying as functions of (1) the degree of infant distress they perceived in the cry, and (2) contextual information relevant to caregiving. In the first study (N = 34), listeners waited longer to respond to cries that they had earlier rated as sounding less distressed than when they heard cries of higher distress. Further, those who had been told that the infant needed sleep waited longer to respond than those without this information. This effect of context information, however, was limited to the latencies; in another study (N = 50), listeners' ratings of distress were not affected. Several acoustic features of the cries correlated with distress ratings and with latencies to signal a caregiving response. Taken together, the results suggest that adults' responses to crying are influenced both by acoustic gradations in the cry itself and by the caregiving context. Ratings of degree of distress manifest in the cry, in other words, may be highly predictive of caregiving behavior but not wholly so. Finally, although certain acoustic variations related to greater perceived distress and speed of response, differences were apparent between infants in the magnitude of these variations. The implication that the general process of cry perception may be calibrated, or fine tuned, to the range of acoustic variation provided by individual infants is discussed.     

Neural Processing of Eye Gaze and Threat‐Related Emotional Facial Expressions in Infancy

Combined with emotional expressions, eye gaze can provide essential information to indicate threat in the environment. The current study assessed the effects of eye gaze direction on infants’ neural processing of fearful and angry faces. Event‐related potentials were recorded from thirteen 7‐month‐old infants. Two face‐sensitive posterior components, the N290 and P400, as well as a frontocentral negative component (Nc), indicating attentional arousal, were sensitive to eye gaze direction and emotion. A larger Nc was observed for angry faces with direct compared to averted eye gaze. Fearful faces elicited a larger N290 than angry faces, whereas angry faces elicited a more prominent P400 regardless of eye gaze direction. The findings are discussed in terms of early social cognitive and neural development.     

Variations in the Availability and Quality of Early Childhood Education and Care by Socioeconomic Status of Neighborhoods

Research Findings: This article provides Australian evidence of the availability and quality of early childhood education and care (ECEC) services in low–socioeconomic status (SES) neighborhoods. There is less availability of ECEC in low-SES areas in Australia, and these programs provide a lower average quality of care than in more advantaged neighborhoods. Families tend to travel short distances to ECEC programs (Mdn = 2.9 km), and therefore families in low-SES areas are limited in the programs they can choose or are faced with higher transport costs than families in more advantaged neighborhoods. This study uses government licensing data from a population of 6,937 ECEC services together with a sample of 2,494 children enrolled in 421 ECEC classrooms. Practice or Policy: Established measures of the local ECEC market tend to overestimate its size and in turn the availability of ECEC. Measures of ECEC market density should be tested for sensitivity to reductions in size. SES gradients are observed within local ECEC markets, meaning that attempts to lift supply and quality in low-SES areas require specific and targeted policy intervention.
