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.     

Evaluation of a Health Careers Program for Asian American and Pacific Islander High School Students

The authors evaluated a health careers program in a U.S. urban public high school. After small subgroups of the original sample were removed, participants included 162 Asian American and Pacific Islander students. Analyses of covariance indicated that, compared with the comparison group, the treatment group reported significantly higher levels of social support, school engagement, interest in learning, vocational expectations, and ethnic identity. Implications for multicultural counseling in schools are discussed. Los autores evaluaron un programa de carreras sanitarias en una escuela secundaria pública de Estados Unidos. Tras la eliminación de pequeños subgrupos de la muestra original, los participantes incluyeron 162 estudiantes Asiático‐Americanos e Isleños del Pacífico. Los análisis de covarianza indicaron que, comparado con el grupo de comparación, el grupo de tratamiento expresó unos niveles significativamente mayores de apoyo social, participación escolar, interés en el aprendizaje, expectativas vocacionales e identidad étnica. Se discuten las implicaciones para la consejería multicultural en escuelas.     

Perfectionism, Coping, Social Support, and Depression in Maltreated Adolescents

The current study examined the associations among dimensions of perfectionism, coping, social support, and depression in 58 adolescents with a history of maltreatment. Participants completed the Child-Adolescent Perfectionism, multidimensional measures of coping and social support, and the CES-D Depression Scale. Correlational analyses showed that depression was associated with socially prescribed perfectionism, internalized emotion-oriented coping, avoidant-oriented distancing, and low family support and peer support. Analyses of coping responses and perfectionism established links between self-oriented perfectionism and internalized emotion-oriented coping responses and self-reliant problem-solving. Socially prescribed perfectionism was associated with avoidance-oriented coping (i.e., distancing). While self-oriented perfectionism and social support were unrelated, socially prescribed perfectionism was associated with reduced levels of family support. Collectively, the findings highlight the roles of poor coping and social support as contributors to the emotional distress experienced by maltreated adolescents. Moreover, it is suggested that the distress experienced by perfectionistic youth with a history of maltreatment reflects, in part, the role of maladaptive coping styles and coping resource deficits. Our findings support further consideration of personality dimensions such as perfectionism as contributors to poor functioning among maltreated youth.     

Predictors of Deliberate Self-Harm Behavior Among Emerging Adolescents: An Initial Test of a Self-Punitiveness Model

The current study examined the extent to which an expanded self-punitiveness model could be applied to deliberate self-harm (DSH) among students making the transition to university. Specific components of the self-punitiveness model included perfectionism, overgeneralization, self-criticism, and shame. A sample of 319 university students completed a measure of deliberate self-harm as well as two multidimensional perfectionism measures and measures of self-criticism, overgeneralization, and shame. Correlational analyses found few significant associations among deliberate self-harm and the self-punitiveness factors among men. In contrast, among women, deliberate self-harm was associated with dimensions of trait perfectionism such as parental criticism and socially prescribed perfectionism, as well as with overgeneralization, self-criticism, and both characterological shame and bodily shame with the strongest associations found with shame. Supplementary analyses found a strong link between overgeneralization and shame and an association between self-criticism and shame among women. The results support the contention that particularly among young women making the transition to university, deliberate self-harm behavior is a reflection of a self-punitive personality orientation with multiple facets and a sense of shame associated with an overgeneralized sense of failing to meet social expectations.     

Assessing Counseling Students' Attitudes Regarding Substance Abuse and Treatment

Undergraduate counselors‐in‐training completed the Substance Abuse Attitude Survey, which measures treatment intervention, treatment optimism, and nonstereotypical attitudes. Treatment optimism was positively correlated with nonstereotypical attitudes and treatment intervention. Results indicated that treatment intervention and nonstereotypical attitudes must be addressed in addiction counseling courses.     

An optimal adjustment procedure to minimize experiment time in decisions with multiple alternatives

Decisions between multiple alternatives typically conform to Hick’s Law: Mean response time increases log-linearly with the number of choice alternatives. We recently demonstrated context effects in Hick’s Law, showing that patterns of response latency and choice accuracy were different for easy versus difficult blocks. The context effect explained previously observed discrepancies in error rate data and provided a new challenge for theoretical accounts of multialternative choice. In the present article, we propose a novel approach to modeling context effects that can be applied to any account that models the speed–accuracy trade-off. The core element of the approach is “optimality” in the way an experimental participant might define it: minimizing the total time spent in the experiment, without making too many errors. We show how this approach can be included in an existing Bayesian model of choice and highlight its ability to fit previous data as well as to predict novel empirical context effects. The model is shown to provide better quantitative fits than a more flexible heuristic account.     

Associations Between Positive Development in Late Adolescence and Social, Health, and Behavioral Outcomes in Young Adulthood

Little is known about positive development across the transition from adolescence to young adulthood. The purpose of this paper was to use longitudinal data from a large community sample, the Australian Temperament Project, to investigate prospective associations between positive development at age 19?C20?years and changes in social, health, and behavioral outcomes at 23?C24?years. Data from 890 young adults (61.7% women) were analyzed using path analysis. Emotional health, physical well-being, friendship quality, reduced antisocial behavior, and positive development in young adulthood were predicted by higher levels of positive development in late adolescence, after controlling for baseline levels of respective outcomes, gender, and family socioeconomic status. Parent relationship quality and alcohol use were not significantly predicted. Based on these findings, interventions promoting positive development during adolescence should be investigated as a potential means of yielding positive social, health, and behavioral consequences well into young adulthood.     

Does syntax contribute to the function of duets in a parrot, Amazona auropalliata?

Complex acoustic signals in many animal species are characterized by a syntax that governs how different notes are combined, but the importance of syntax to the communicative function of signals is not well understood. Mated pairs of yellow-naped amazons, Amazona auropalliata, produce coordinated vocal duets that are used for territory maintenance and defense. These duets follow rules that specify the ordering of notes within duets, such as a strict alternation of sex-specific notes and a defined progression of note types through each duet. These syntactical rules may function to define sex-specific roles, improve coordination, and allow individuals to combine calls into meaningful sequences. As a first step toward understanding the functional significance of syntax, we conducted two separate audio playback experiments in which we presented nesting pairs with normal duets and duets with broken syntax (i.e., one of the syntactic rules was broken). In Experiment One, we reversed the order of female and male notes within note pairs while retaining the typical progression of note types through a duet. In Experiment Two we reversed the order of note types across a whole duet while retaining the typical female-male ordering within note pairs. We hypothesized that duets with broken syntax would be less-effective signals than duets with normal syntax and predicted that pairs would respond less to broken syntax than to normal duets. Contrary to predictions, we did not observe differences in response between treatments for any variables except latency to approach the speaker. After we combined data across experiments post hoc, we observed longer latencies to approach the speakers after playbacks of broken syntax duets, suggesting that pairs could differentiate between playbacks. These responses suggest that breaking one rule of duet syntax at a time does not result in detectable loss of signal efficacy in the context of territorial intrusions.
