Birth Weight and Childhood Psychopathology in the ABCD Cohort: Association is Strongest for Attention Problems and is Moderated by Sex

Research on Child and Adolescent Psychopathology - Many studies have shown low birth weight is associated with psychopathology later in life, particularly attention-deficit/hyperactivity disorder...     

Getting ready: Results of a randomized trial of a relationship‐focused intervention on the parent–infant relationship in rural early head start

The purpose of this study is to investigate the effects of a relational intervention (the Getting Ready intervention) on parenting behaviors supporting the parent–infant relationship for families enrolled in Early Head Start home‐based programming. Two‐hundred thirty‐four parents and their children participated in the randomized study, with 42% of parents reporting education of less than a high‐school diploma. Brief, semistructured parent–child interaction tasks were videotaped every 4 months over a16‐month intervention period. Observational codes of parent–infant relationship behaviors included quality of three parental behaviors: warmth and sensitivity, support for learning, and encouragement of autonomy; two appropriateness indicators: support for learning and guidance/directives; and one amount indicator: constructive behaviors. Parents who participated in the Getting Ready intervention demonstrated higher quality interactions with their children that included enhanced quality of warmth and sensitivity, and support for their children's autonomy than did parents in the control group. They also were more likely to use appropriate directives with their children and more likely to demonstrate appropriate supports for their young children's learning. Results indicate an added value of the Getting Ready intervention for Early Head Start home‐based programming for families of infants and toddlers.     

Peripheral oxytocin administration buffers autonomic but not behavioral responses to environmental stressors in isolated prairie voles

Negative social experiences such as social stressors and isolation influence mental and physical illnesses, including affective disorders and heart disease. Studies focused on socially monogamous prairie voles can provide insight into neurobiological systems that underlie the consequences of negative social interactions. Female prairie voles were exposed to 28 days of social isolation or pairing with a female sibling (control). Voles were administered daily oxytocin [20 μg/50 μl, subcutaneous (sc)] or saline vehicle (50 μl, sc) for 14 days and exposed to two behavioral stressors [elevated plus maze (EPM) and resident-intruder test]. Brain tissue was collected for analysis of central peptide levels in the hypothalamic paraventricular nucleus (PVN). Isolation produced autonomic changes [increased heart rate (HR) and decreased HR variability) during both acute stressors and increased anxiety behaviors in the EPM. Oxytocin injection prevented the autonomic consequences of the acute stressors in isolated prairie voles, but did not affect the behaviors tested under the present conditions. Oxytocin had no effect on the behavioral or autonomic responsiveness in paired prairie voles. Oxytocin injection may exert a beneficial effect on autonomic responses to stressors in isolated animals through increasing the number of oxytocin-containing neurons and decreasing the number of corticotropin-releasing hormone-containing neurons in the PVN. Oxytocinergic mechanisms may serve to compensate for autonomic responses associated with chronic isolation and exposure to both social and non-social acute stressors.     

A 10-day developmental voyage: converging evidence from three studies showing that self-esteem may be elevated and maintained without negative outcomes

Empirical evidence shows that educational experiences in the context of the outdoors lead to elevated self-esteem. Although elevated self-esteem is widely assumed to promote beneficial outcomes, recent evidence suggests that elevated self-esteem may also facilitate a variety of negative outcomes (i.e., increased prejudice, aggression, drug and alcohol abuse). The current research was conducted in order to examine whether one type of outdoor educational experience—a 10-day developmental voyage—could elevate adolescents’ self-esteem without also elevating negative outcomes. The data from three separate studies are reported. Study one revealed that adolescents who undertook the voyage manifested elevated self-esteem and decreased gender prejudice (i.e., less negative ratings of opposite sex outgroup members). Study two replicated these findings and further demonstrated that these effects were maintained 4–5 months following the voyage. In study three, in addition to self-esteem, risky attitudes (i.e., towards drug and alcohol use), physical aggression, verbal aggression, racial and gender bias were also examined. Adolescents again showed elevated self-esteem that was maintained 4–5 months following the voyage. There were no changes in risky attitudes, aggression, or racial and gender bias. Taken together these results indicate that taking part in a 10-day developmental voyage—can lead to an elevation in self-esteem, that is maintained over time and which does not facilitate a variety of negative outcomes.     

Biased attentional processing of positive stimuli in social anxiety disorder: an eye movement study

Despite the established relationship between social anxiety and attentional bias towards threat, a growing base of evidence suggests that social anxiety is additionally maintained by a deficit in the attentional processing of positive information. However, it remains unclear which component of attention is implicated in this deficit. Using eye movement-based measures and a novel attentional cuing methodology, the present study sought to investigate the presence of anxiety-linked bias in attentional engagement with, attentional disengagement from, and total fixation time to, socially relevant emotional stimuli in individuals diagnosed with social anxiety disorder, relative to non-socially anxious controls. Socially anxious individuals were found to exhibit faster attentional disengagement from positive stimuli, and reduced total fixation time to all emotional stimuli, relative to controls. Additionally for socially anxious individuals, lower total fixation times to positive stimuli were associated with higher levels of state anxiety. No differential pattern of engagement was evident between groups. We conclude that social anxiety is maintained in part by the aberrant processing of positive social stimuli.     

The role of disgust emotions in the observer response to facial disfigurement

Social intrusions by observers are commonly reported by those with disfiguring conditions. This study examined the role of disgust emotions in the observer response. A group of students (N = 48) completed quantitative questionnaires measuring extent of disfigurement, whilst viewing images of faces with varying disfigurements. Another group of students (N = 84) completed quantitative questionnaires measuring level of disgust elicited by the same images. Disgust sensitivity was measured using the Disgust Scale Revised. Observers reported greater levels of disgust (p < .01) with increasing severity of facial disfigurement. Individuals with a higher disgust sensitivity reported increased levels of disgust in response to faces of mild (p = .03), moderate (p = .02) and severe (p < .01) disfigurement compared to those with a lower disgust sensitivity. This provides an explanatory framework for the avoidance reactions of observers and may be important in understanding variability in adjustment following disfigurement.

Gist perception requires attention

Four experiments (240 subjects) explored gist perception without attention using the Mack and Rock (1998) cross task. Twelve scenes were flashed under conditions of inattention, divided, and full attention. Subjects described what they saw on critical trials in which a scene was flashed with the cross. In Experiments 3 and 4 subjects also chose the scene from a four scene array. In Experiment 4 the critical scenes were shown twice in the inattention condition. Overall, only 17% reported gist in the inattention condition, 65% did so with divided, and 82% did so with full attention. In Experiment 4 most subjects remained inattentionally blind to the scenes even though they were shown twice, conditions which fostered repetition priming, and we found a suggestion of negative priming. The results of all 4 experiments indicate that gist requires attention.     

Iconic memory for natural scenes: Evidence using a modified change-detection procedure

ABSTRACT

Change blindness for the contents of natural scenes suggests that only items that are attended while the scene is still visible are stored, leading some to characterize our visual experiences as sparse. Experiments on iconic memory for arrays of discrete symbols or objects, however, indicate observers have access to more visual information for at least several hundred milliseconds at offset of a display. In the experiment presented here, we demonstrate an iconic memory for complex natural or real-world scenes. Using a modified change detection task in which to-be changed objects are cued at offset of the scene, we show that more information from a natural scene is briefly stored than change blindness predicts and more than is contained in visual short-term memory. In our experiment, a cue appearing 0, 300, or 1000?msec after offset of the pre-change scene or at onset of the second scene presentation (a Post Cue) directed attention to the location of a possible change. Compared to a no-cue condition, subjects were significantly better at detecting changes and identifying what changed in the cue condition, with the cue having a diminishing effect as a function of time and no effect when its onset coincided with that of the second scene presentation. The results suggest that an iconic memory of a natural scene exists for at least 1000?msec after scene offset, from which subjects can access the identity of items in the pre-change scene. This implies that change blindness underestimates the amount of information available to the visual system from a brief glance of a natural scene.     

Retrospective studies of the origins of phobias: A review

Abstract

Studies using retrospective subject reports to investigate etiological models of fears and phobias are reviewed. It is argued that the research effort to date has been plagued by a multitude of methodological problems which bring into question the validity of the major findings. In particular, it is shown that most investigators have begun with the assumption that all phobias are indebted to some traumatic experience with the object or situation and, as a result of this assumption, have predisposed themselves to support learning-based accounts of phobia onset. Other problems, including the lack of demonstrations of adequate levels of inter-rater reliability, test-retest reliability and construct validity are also discussed. Finally, recommendations for future research are made.
