Supportive Non-Parental Adults and Adolescent Psychosocial Functioning: Using Social Support as a Theoretical Framework

Supportive Non-Parental Adults (SNPAs), or non-parental adults who provide social support to youth, are present in the lives of many adolescents; yet to date, a guiding framework for organizing the existing literature on the provision of support provided by multiple types of SNPAS, such as teachers, natural mentors, and extended family members, as well as to inform future research efforts, is lacking. The aim of the current paper is to utilize the well-established lens of social support to integrate, across this broad range of literatures, recent findings regarding associations between SNPAs and four indices of adolescent psychosocial adjustment: academic functioning, self-esteem, and behavioral and emotional problems. Beyond offering an integrative framework for understanding the link between SNPAs and adolescent functioning, the issues reviewed here have potentially far-reaching consequences for adolescents and their families, as well as the professionals working with adolescents and their families in the health care, school, and community settings.     

Optimism facilitates the utilisation of prior cues

It has been shown that optimists tend to rely more on their prior expectations than sensory input when making decisions of an intense nature (Geers & Lassiter, 2002). We investigated the degree to which this tendency persists over a range of discrepancies between prior cues and actual stimuli. Eighty‐seven participants were shown a subset of happy, sad and fearful pictures drawn from the Ekman facial expressions of emotion (Ekman & Oster, 1979). Each picture was preceded by a verbal cue indicating the impending emotional expression and intensity. The displayed pictures were either in agreement, slightly discrepant or very discrepant with the cue. Participants rated the extent to which they agreed/disagreed with the expectation cue. Probit signal detection models were used to produce acquiescence for each subject at each level of discrepancy. Correlation analysis was performed on acquiescence and dispositional optimism scores. There was a significant correlation between all acquiescence scores for levels of discrepancies and dispositional optimism. Optimism appears to be a trait associated with acquiescence. The apparent tendency of optimists to comply may be due to a cognitive style that relies on expectations, such that it takes them longer to recognise the extent of discrepancy between expectations and incoming information.

Known risk factors for violence predict 12-month-old infants' aggressiveness with peers

This study tested the hypothesis that 12-month-old infants' use of force against peers is associated with known risk factors for violence. We conducted a prospective longitudinal study, which included laboratory observations of firstborn British infants (N = 271) during simulated birthday parties. No gender differences in aggressiveness were observed. The infants' observed aggressiveness was significantly correlated with mothers' mood disorder during pregnancy and with mothers' history of conduct problems. Infants' observed aggressiveness was correlated with parents' ratings of infants' anger and aggression, which were also predicted by mothers' mood disorder and history of conduct problems. Our findings indicate that infants at risk for serious aggression can already be identified when the motor ability to use physical force first enters the human repertoire.     

Applied behavior analysis is ideal for the development of a land mine detection technology using animals

The detection and subsequent removal of land mines and unexploded ordnance (UXO) from many developing countries are slow, expensive, and dangerous tasks, but have the potential to improve the well-being of millions of people. Consequently, those involved with humanitarian mine and UXO clearance are actively searching for new and more efficient detection technologies. Remote explosive scent tracing (REST) using trained dogs has the potential to be one such technology. However, details regarding how best to train, test, and deploy dogs in this role have never been made publicly available. This article describes how the key characteristics of applied behavior analysis, as described by Baer, Wolf and Risley (1968, 1987), served as important objectives for the research and development of the behavioral technology component of REST while the author worked in humanitarian demining.     

Overshadowing and associability change

Three appetitive Pavlovian conditioning experiments with rats examined the associability of stimuli A and B that had a history of compound conditioning (AB+), relative to stimuli X and Y that had a history of conditioning in isolation (X+, Y+). Following this training, Experiment 1 revealed that conditioned responding was higher to X and Y than to A and B (overshadowing). In a subsequent AY+, AX-, BY- test discrimination, the AY/BY discrimination was solved more readily than the AY/AX discrimination. In Experiment 2, following AB+, X+, Y+ training, A and Y were presented as a compound and signaled the availability of reinforcement upon the performance of an instrumental response. Test trials in which A and Y were presented alone, and in extinction, revealed that A acquired greater control of instrumental responding than Y. Experiment 3 revealed that following AB+, X+, Y+ training, A and B served as more effective discriminative stimuli for instrumental responding than X and Y. Overall, these results imply that the associability of stimuli conditioned in compound is higher than stimuli conditioned in isolation. These results are discussed in terms of attentional theories of associative learning.     

Approaching the familiar: On the ability of mere exposure to direct approach and avoidance behavior

The mere-exposure literature has shown that familiar objects are preferred to novel objects. However, no work has definitively shown that mere exposure can direct and facilitate approach movements. In Experiment 1, participants were shown stimuli and were later re-exposed to them along with novel stimuli. Participants were directed to make an approach or avoidant motion to each and response times were recorded. As predicted, participants were quicker to approach and slower to avoid familiar relative to novel stimuli. In Experiment 2, participants were shown mere-exposed and novel symbols and were asked to “push” or “pull” a joystick in response to each, based on their intuition. Extending Experiment 1’s findings, participants freely selected an approach response more frequently for familiar compared to novel stimuli. Moreover, in this same experiment, familiar stimuli were judged as more likeable than were novel stimuli, and participants’ liking for familiar stimuli correlated with the frequency with which they were approached. Implications of these findings are discussed.     

Accuracy in assessment of self-reported stress and a measure of health from static facial information

The human face is important for social communication and in attractiveness judgements. Previous studies indicate that several facial traits may be related to mental and physical health and there is some evidence that individuals are able to judge past health on the basis of facial appearance. The current study builds on this prior work, examining the relationship between static facial appearance and self-reported stress and health. Specifically, we examined (1) within and between individual stress (Study 1) by photographing the same participants at two times, once in a relatively stress free and once in a stressful time, and (2) between individual health (Studies 2A and 2B) by examining self-reported past number of colds as a measure of immune function. All studies demonstrated that individuals could judge the stress and physical health of others from static facial appearance alone at rates greater than chance. Such accuracy may reflect selection pressures to identify stress free and healthy social partners.     

The School Change Feedback Process: Creating a New Role for Counselors in Education Reform

The authors present the results of a multiyear collaborative research project that involved a counselor educator, graduate‐level school counseling students, and school personnel in defining a new role for counselors in education reform. This collaborative effort was based on an innovative conceptual framework that informs school counselors about specific schooling processes that can either enhance or hinder student academic, personal/social, and career development.
