Individual Differences in Infant Oculomotor Behavior During the Viewing of Complex Naturalistic Scenes

Little research hitherto has examined how individual differences in attention, as assessed using standard experimental paradigms, relate to individual differences in how attention is spontaneously allocated in more naturalistic contexts. Here, we analyzed the time intervals between refoveating eye movements (fixation durations) while typically developing 11‐month‐old infants viewed a 90‐min battery ranging from complex dynamic to noncomplex static materials. The same infants also completed experimental assessments of cognitive control, psychomotor reaction times (RT), processing speed (indexed via peak look during habituation), and arousal (indexed via tonic pupil size). High test–retest reliability was found for fixation duration, across testing sessions and across types of viewing material. Increased cognitive control and increased arousal were associated with reduced variability in fixation duration. For fixations to dynamic stimuli, in which a large proportion of saccades may be exogenously cued, we found that psychomotor RT measures were most predictive of mean fixation duration; for fixations to static stimuli, in contrast, in which there is less exogenous attentional capture, we found that psychomotor RT did not predict performance, but that measures of cognitive control and arousal did. The implications of these findings for understanding the development of attentional control in naturalistic settings are discussed.     

Neural Correlates of Individual Differences in Infant Visual Attention and Recognition Memory

Past studies have identified individual differences in infant visual attention based upon peak look duration during initial exposure to a stimulus. Colombo and colleagues found that infants that demonstrate brief visual fixations (i.e., short lookers) during familiarization are more likely to demonstrate evidence of recognition memory during subsequent stimulus exposure than infants that demonstrate long visual fixations (i.e., long lookers). This study utilized event‐related potentials (ERPs) to examine possible neural mechanisms associated with individual differences in visual attention and recognition memory for 6‐ and 7.5‐month‐old infants. Short‐ and long‐looking infants viewed images of familiar and novel objects during ERP testing. There was a stimulus type by looker type interaction at temporal and frontal electrodes on the late slow wave (LSW). Short lookers demonstrated an LSW that was significantly greater in amplitude in response to novel stimulus presentations. No significant differences in LSW amplitude were found based on stimulus type for long lookers. These results indicate deeper processing and recognition memory of the familiar stimulus for short lookers.     

Infant Distress and Regulatory Behaviors Vary as a Function of Attachment Security Regardless of Emotion Context and Maternal Involvement

Differences in infant distress and regulatory behaviors based on the quality of attachment to mother, emotion context (frustration versus fear), and whether or not mothers were actively involved in the emotion-eliciting tasks were examined in a sample of 98 16-month-old infants and their mothers. Dyads participated in the Strange Situation, a limiting task designed to elicit infant frustration, and a novelty task designed to elicit infant fear. Mothers were asked to remain uninvolved during the first minute of each task, and then instructed to engage with their infants as they wished for the remaining three minutes. Independent of concurrent maternal sensitivity, resistant infants were significantly more distressed than secure and avoidant infants. Avoidant infants engaged in fewer active mother-oriented regulation behaviors than secure and resistant infants and engaged in more self-soothing in the mother involved condition than the mother uninvolved condition. Resistant infants engaged in more physical comfort with their mothers and more venting than both secure and avoidant infants, and exhibited a smaller variety of adaptive non-mother-oriented strategies than did secure infants. There were few differences in infant distress and regulatory behaviors as a function of emotion task and maternal involvement. Limitations and implications for future research are discussed.     

Physiological Reactivity to Infant Crying and Observed Maternal Sensitivity

Relations between maternal sensitivity and physiological reactivity to infant crying were examined using measures of heart rate (HR) and respiratory sinus arrhythmia (RSA) in 49 mothers of second‐born infants. Using the Ainsworth Sensitivity Scale, an independent assessment of maternal sensitivity was made during maternal free play and bathing of their infants. Physiological reactivity was measured while mothers listened to three blocks of infant cry sounds in a standard cry paradigm. Mothers scoring high on sensitivity were compared to less sensitive mothers on both their physiological reactivity to the presented crying sounds and their physiological mean‐level differences. Significant interaction effects were found for both HR and RSA. Highly sensitive mothers showed a larger increase in HR and stronger RSA withdrawal in response to the first block of cry sounds compared to less sensitive mothers. Main effects showed that highly sensitive mothers had lower mean overall HR, and higher mean RSA levels across all three blocks of crying sounds compared to less sensitive mothers. RSA withdrawal and accompanying HR increases are discussed from a polyvagal perspective as indicative of a better capability in responding to infant signals of negative affect.     

Infant responses to frustration: Individual differences in the expression of negative affect

The purpose of this study was to examine the contribution of infant characteristics (temperament and motivation) and parental expressivity to infants' emotional response to frustration. Subjects were 84 10-month-old infants and their families. Frustration was created by having infants and mothers play with a toy after which mothers were cued to remove the toy from the infants' reach but within their sight. After two minutes, the toy was returned to the infants. The infants' emotional responses were measured in two ways, vocally and facially. Infant motivation was coded by noting the degree to which the infant was interested and positively involved with the toy. Infant temperament was obtained through mother report. Parental reports of their own emotional expressivity were obtained through questionnaire. The results indicated that the degree to which infants were interested in the toy predicted the intensity with which they became angry when the toy was removed. Parental expressivity and infant temperament were also related to emotion expressivity. Fathers' but not mothers' negative expressivity was associated with infants' expression of anger and distress but in a negative direction.This research was supported by a Small Grant from the National Institute of Mental Health (#MH 44324) and a grant from the Pennsylvania State University Biomedical Research Support Grant Program awarded to the first author. The authors wish to thank the mothers and infants who participated in the study.     

Contribution of Motion Information to Maternal Face Discrimination in Infancy

The contribution of motion and feature invariant information in infants' discrimination of maternal versus female stranger faces was assessed. Using an infant controlled habituation–dishabituation procedure, 4‐ and 8‐month‐old infants (N = 62) were tested for their ability to discriminate between their mother and a female stranger in 4 different conditions varying whether motion or feature information about the faces was available. The faces were presented in a still or dynamic video image with either a positive or a negative contrast. In each condition, infants habituated to a stranger's face and then viewed, in 3 pairs of alternating novelty test trials, either a new stranger or their mother's face. Results show that motion information contributes to the 8‐month‐old infants', but not the 4‐month‐old infants' discrimination of maternal faces. These results are interpreted in relation to recent findings and models in the adult literature suggesting that there is an enhanced contribution of dynamic information in face recognition when the face is familiar. Our data confirm that from the outset, there is a complex interplay of feature and motion information in the discrimination of the mother's face when the viewing condition is not optimal.     

Integrating Individual Differences in Career Assessment: The Atlas Model of Individual Differences and the Strong Ring

Career assessment methods often include measures of individual differences constructs, such as interests, personality, abilities, and values. Although many researchers have recently called for the development of integrated models, career counseling professionals have long faced the challenge of integrating this information into their practice. The authors examine the use of integrated models to enhance the career counseling process, including Armstrong, Day, McVay, and Rounds's (2008) RIASEC‐based Atlas Model of Individual Differences (using Holland's 1997, typology of 6 interest types: Realistic, Investigative, Artistic, Social, Enterprising, and Conventional [RIASEC]) and Armstrong, Smith, Donnay, and Rounds's (2004) basic interests‐based Strong Ring. These models provide a structured framework for presenting clients with assessment feedback that emphasizes connections between interests, personality, and abilities.     

Self‐Soothing — A Recursive Intrapsychic and Relational Process: The Contribution of the Bowen Theory to the Process of Self‐Soothing

The concept of self‐soothing originating in the psychodynamic tradition has attracted interest from therapists as a key skill in the managing and regulating of strong affect and emotional discomfort. While a capacity for self‐soothing is implicit in, and a vital prerequisite to, the process of differentiation, Murray Bowen also predicted that the outcome of increased differentiation is improved emotional equilibrium and a capacity for self‐soothing, clearly a recursive process. The attention of Bowen family systems theory to both the relational and intrapsychic aspects of human functioning provides a useful framework through which to explore these aspects of the dynamics of self‐soothing. This article describes some of the key processes involved in developing a self‐soothing capacity within an effort to define a more autonomous self in significant relationships. The author contrasts Family Systems thinking with other theoretical perspectives that speak to the importance of self‐soothing. Finally, the role of the therapist as a facilitator of an environment in which the self‐soothing resources of clients can emerge is considered alongside suggestions and strategies for how a therapist may contribute to a client's own efforts.     

Accentuation of Individual Differences in Social Competence During the Transition to Adolescence

Using a sample of individuals (277 males, 315 females) studied since birth in the National Institute of Child Health and Human Development Study of Early Child Care and Youth Development, the present study investigated how early pubertal maturation and school transition alter youth trajectories of social competence during the transition to adolescence. Social competence showed strong continuity, with the most socially competent children remaining so in adolescence. Early pubertal maturation and school transitions accentuate individual differences, increasing social competence among more competent youth, but further diminishing social competence among less competent individuals. In essence, facing challenges that require social competence may further separate competent individuals from less competent peers. Thus, the psychosocially rich become richer, while the psychosocially poor become poorer.     

Modeling Age Differences in Infant Category Learning

We used an encoder version of cascade correlation to simulate Younger and Cohen's (1983, 1986) finding that 10‐month‐olds recover attention on the basis of correlations among stimulus features, but 4‐ and 7‐month‐olds recover attention on the basis of stimulus features. We captured these effects by varying the score threshold parameter in cascade correlation, which controls how deeply training patterns are learned. When networks learned deeply, they showed more error to uncorrelated than to correlated test patterns, indicating that they abstracted correlations during familiarization. When prevented from learning deeply, networks decreased error during familiarization and showed as much error to correlated as to uncorrelated tests but less than to test items with novel features, indicating that they learned features but not correlations among features. Our explanation is that older infants learn more from the same exposure than do younger infants. Unlike previous explanations that postulate unspecified qualitative shifts in processing with age, our explanation focuses on quantitatively deeper learning with increasing age. Finally, we provide some new empirical evidence to support this explanation.     

Maternal Psychosocial Adversity and the Longitudinal Development of Infant Sleep

Research has identified associations between indicators of social disadvantage and the presence of child sleep problems. We examined the longitudinal development of infant sleep in families experiencing high (n = 58) or low (n = 64) levels of psychosocial adversity, and the contributions of neonatal self‐regulatory capacities and maternal settling strategies to this development. Assessments of infant sleep at 4‐, 7‐, and 12‐weeks postpartum indicated no differences in sleeping difficulties between high‐ and low‐adversity groups. However, more infant sleep difficulties were reported in the high‐ versus low‐adversity groups at 12‐ and 18‐month follow‐ups. Neonatal self‐regulatory capacities were not related to the presence or absence of adversity, or to subsequent infant sleep quality. However, there were group differences in maternal settling strategies that did predict subsequent infant sleep difficulties. The pattern of sleep disturbance observed in association with maternal psychosocial adversity at 18‐months was consistent with risk for broader impairments in child functioning.     

Volunteering to Assist the Homeless: Public Service and Individual Differences

Abstract

The present investigation examined the effects of three public service announcements (PSAs) on undergraduates’ willingness to volunteer to assist the homeless at a local emergency shelter. A PSA designed to arouse empathy in listeners generally yielded a higher rate of volunteering to assist the homeless than either a self-oriented PSA or an unemotional, other-oriented PSA. The PSA designed to arouse empathy was found to be especially effective in promoting volunteering in individuals who scored relatively high on trait affective empathy and who, in turn, reported a relatively strong empathic response to this message.     

Internalizing Symptoms in Adolescents: Gender Differences in Vulnerability to Parental Distress and Discord

This longitudinal study investigated gender differences in the relation between (1) internalizing symptoms of depression and anxiety reported by adolescents, and (2) emotional distress and marital discord reported by their mothers. Structural equation modeling was used to track the relationship between these variables in a community sample of 116 males and 101 females and their parents across three data intervals roughly corresponding to early adolescence (M = 11,4), mid‐adolescence (M = 13,7), and late adolescence/early adulthood (M = 19,2). For early adolescents, there were no gender differences in the relation between internalizing symptoms and parental distress and discord. Gender differences did emerge, however, by midadolescence, at which time parental disturbances were significantly associated with internalizing symptoms in adolescent females but not adolescent males. The emergence of this risk factor during this developmental phase may help account for frequent findings that place adolescent females at higher risk for anxiety and depression than adolescent males.     

Individual Differences in Hand Movements During Deception

This article addresses the influence of 2 personality traits on making hand movements during deception, namely public self-consciousness and ability to control behavior. It was hypothesized that especially individuals with high public self-consciousness and individuals who are skilled in controlling their behavior would make fewer hand movements during deception compared to truth-telling. A total of 56 participants were interviewed twice; in one interview they told the truth and in the other interview they lied. Before the interviews the participants completed a personality inventory to measure their levels of public self-consciousness and ability to control their behavior. The results supported the hypotheses. Some implications of these findings are discussed.     

Individual and Gender Differences in Sexual Self-Perceptions

Abstract

A study was conducted to explore the perceptions that individuals have about the sexual component of their self-concept while paying particular attention to gender differences. A list of sexual traits was created that described various components of an individual's sexuality. As predicted, we found that males rate themselves higher on explicitly sexual dimensions (e.g., sexually responsive, experienced) and females perceive themselves to be more romantic and sexually attractive. We also examined how some individual difference variables (masculinity-femininity, erotopho-bia-erotophilia, and sexual experience) may be associated with people's perceptions of their sexuality. For males, masculinity was associated with higher self-ratings on sexual traits related to sexual experience and responsiveness, whereas for females, femininity was associated with higher self-ratings of romanticism and attractiveness. Also, we found that erotophiles and sexually experienced individuals perceive themselves as more sexual than erotophobes and less experienced individuals. The results were discussed in terms of traditional theories about the self-concept and suggestions for further investigations of these issues were noted.     

Infant Emotionality: Observational Methods and the Validity of Maternal Reports

This study was designed to improve the observational measurement of emotionality, and to test factors that influence the validity of maternal reports. More than 150 infants were visited at home with their mothers, two thirds of whom were depressed. These visits yielded 4 different observational measures of positive and negative emotionality at both 6 and 9 months. These were standard assessments (based on LabTab), naturalistic interactions, atypical reactions to the standard assessments, and the still‐face procedure. Atypical reactions were consistently related to traditional measures of emotionality. Responses to the still‐face procedure also generally cohered with the other measures. Aggregation improved agreement between mothers and observers. Depressed mothers' reports of negative emotionality were less accurate at 6 months than those of nondepressed mothers. Parenting experience appeared to be associated with greater maternal accuracy. Taken together the findings provide some support for both sides of the controversy surrounding the validity of maternal reports.     

Becoming a Communicative Partner: Infant Contingent Responsiveness to Maternal Language and Gestures

Infant contingent responsiveness to maternal language and gestures was examined in 190 Mexican American, Dominican American, and African American infant–mother dyads when infants were 14 and 24 months. Dyads were video‐recorded during book‐sharing and play. Videos were coded for the timing of infants’ vocalizations and gestures and mothers’ referential language (i.e., statements that inform infants about objects and events in the world; e.g., “That's a big doggy!”), regulatory language (i.e., statements that regulate infants’ attention or actions; e.g., “Look at that”, “Put it down!”), and gestures. Infants of all three ethnicities responded within 3 sec of mothers’ language and gestures, increased their responsiveness over development, and displayed specificity in their responses: They vocalized and gestured following mothers’ referential language and gestures, but were less likely than chance to communicate following mothers’ regulatory language. At an individual level, responsive infants had responsive mothers.     

A Multilevel Analysis of Gender Differences in Psychological Distress Over Time

Females have higher rates of depression than males, a disparity that emerges in adolescence and persists into adulthood. This study uses hierarchical linear modeling to assess the effects of school context on gender differences in depressive symptoms among adolescents based on two waves of data from the National Longitudinal Study of Adolescent Health (N=9,709 teens, 127 schools). Analysis indicates significant school‐level variation in both overall symptom levels and the average gender gap in depression net of prior symptoms and individual‐level covariates. Aggregate levels of depressive symptomatology were positively associated with contextual‐level socioeconomic status (SES) disadvantage. A cross‐level contingency emerged for the relationship between gender and depressive symptoms with school SES and aggregate perceived community safety such that the gender “gap” was most apparent in contexts characterized by low SES disadvantage and high levels of perceived safety. These results highlight the importance of context to understanding the development of mental health disparities.
