COMPETITION BETWEEN POSITIVE AND NEGATIVE REINFORCEMENT IN THE TREATMENT OF ESCAPE BEHAVIOR

We compared the effects of reinforcing compliance with either positive reinforcement (edible items) or negative reinforcement (a break) on 5 participants' escape-maintained problem behavior. Both procedures were assessed with or without extinction. Results showed that compliance was higher and problem behavior was lower for all participants when compliance produced an edible item rather than a break. Treatment gains were achieved without the use of extinction. Results are discussed regarding the use of positive reinforcement to treat escape behavior.     

Images of God and the imaginary in the face of loss: a quantitative research on Vietnamese immigrants living in Canada

ABSTRACT

This study examines the relationships between images of God, the imaginary and experiences of loss among Vietnamese immigrants living in Canada. One hundred twenty-nine participants completed four sets of questionnaires: a demographic questionnaire, a Questionnaire on God Image, the Brief Symptom Inventory, the Davidson Trauma Scale. In the second phase, 32 participants were administered the AT.9 test (an archetypal test with nine elements). In this test, participants are asked to draw, using nine symbolic elements, and then write a story based on their drawing. Results showed that a positive perception of God negatively correlated with somatisation, anxiety and hostility, whereas negative God image was significantly related to high levels of emotional distress. Results also showed that the synthetic categories of the imaginary were associated with a positive perception of God; and were negatively associated with somatisation, intrusion and hyper-vigilance. Further discussions on the main findings will address cultural implications in the fields of Mental Health, Religion and Culture.     

What's parenting got to do with it: emotional autonomy and brain and behavioral responses to emotional conflict in children and adolescents

Healthy parenting may be protective against the development of emotional psychopathology, particularly for children reared in stressful environments. Little is known, however, about the brain and behavioral mechanisms underlying this association, particularly during childhood and adolescence, when emotional disorders frequently emerge. Here, we demonstrate that psychological control, a parenting strategy known to limit socioemotional development in children, is associated with altered brain and behavioral responses to emotional conflict in 27 at‐risk (urban, lower income) youth, ages 9–16. In particular, youth reporting higher parental psychological control demonstrated lower activity in the left anterior insula, a brain area involved in emotion conflict processing, and submitted faster but less accurate behavioral responses—possibly reflecting an avoidant pattern. Effects were not replicated for parental care, and did not generalize to an analogous nonemotional conflict task. We also find evidence that behavioral responses to emotional conflict bridge the previously reported link between parental overcontrol and anxiety in children. Effects of psychological control may reflect a parenting style that limits opportunities to practice self‐regulation when faced with emotionally charged situations. Results support the notion that parenting strategies that facilitate appropriate amounts of socioemotional competence and autonomy in children may be protective against social and emotional difficulties.     

Visitor Usage of Digital and Physical Artifacts in Two Museum Programs

ABSTRACT

This article reports on a study designed to explore how digital and physical reproductions of original artifacts could be incorporated into museum programs that teach visitors about mechanical motion. Museum visitors were introduced to 3 different types of models through 2 different programs: an engineering design challenge and an exhibit interpretation exploring mechanical motion in every-day objects. Research, based on visitor observation and interviews (n = 79), explored how user interaction with the digital and physical models compared with interactions with the original artifacts, assessed what effect the integration of digital and physical models had on learning, and examined what the learning experience looked like for learners using the mechanisms in the museum activities. Analysis of the learning conversations in additional in-depth case studies (n = 8) for both programs provides a detailed look at how visitors integrated the 3 different model types into their group's experience. Results showed that visitors' usage of, attitudes toward, and learning from the three different types of mechanical models varied based on the visitor or educators' perceived value of the particular model, which was impacted by the context in which the objects were presented.     

Dating Violence Perpetration: The Predictive Roles of Maternally versus Paternally Perpetrated Childhood Abuse and Subsequent Dating Violence Attitudes and Behaviors

This study investigated both young men's and young women's perpetration of physical, sexual, and psychological forms of dating violence, examining predictors of violence including maternally or paternally perpetrated forms of various types of child maltreatment, as well as attitudes toward dating violence and dating violence victimization. Results of hierarchical linear regressions found that childhood experiences of maternal neglect predicted men's physical perpetration, and childhood sexual abuse predicted women's sexual perpetration and men's psychological perpetration. Further, positive attitudes toward dating violence predicted women's physical, psychological, and sexual perpetration, as well as men's sexual perpetration, and experiences of dating violence victimization were the strongest predictors of most forms of dating violence perpetration, particularly among women. Implications for future research and prevention initiatives are discussed.     

Top-down attentional modulation of spatial frequency processing in scene perception

Recent evidence suggests that spatial frequency (SF) processing of simple and complex visual patterns is flexible. The use of spatial scale in scene perception seems to be influenced by people's expectations. However as yet there is no direct evidence for top-down attentional effects on flexible scale use in scene perception. In two experiments we provide such evidence. We presented participants with low- and high-pass SF filtered scenes and cued their attention to the relevant scale. In Experiment 1 we subsequently presented them with hybrid scenes (both low- and high-pass scenes present). We observed that participants reported detecting the cued component of hybrids. To explore if this might be due to decision biases, in Experiment 2, we replaced hybrids with images containing meaningful scenes at uncued SFs and noise at the cued SFs (invalid cueing). We found that participants performed poorly on invalid cueing trials. These findings are consistent with top-down attentional modulation of early spatial frequency processing in scene perception.
