Using the Good Behavior Game with High School Special Education Students: Comparing Student- and Teacher-Selected Reinforcers

The authors investigated the implementation of the Good Behavior Game (GBG) on disruptive behaviors of high school special education students. Additionally, the study compared the effect of student-selected rewards versus teacher-selected rewards. A multielement withdrawal (A/[B?+?C]/A/[B?+?C]) design was used in the classroom to monitor behavior and compare the reward topography. Results suggested that the GBG decreased the frequency of disruptive behavior in both teams; however, there were no notable differences across reward type for either team. Effect sizes were reported using nonoverlap of all pairs. Nonoverlap of all pairs scores indicated moderate-to-large effects for the GBG, but small effects for reward topographies. Limitations and future directions are also discussed.     

Alcohol Use in Adolescent Twins and Affiliation with Substance Using Peers

Affiliation with substance using peers is one of the strongest predictors of adolescent alcohol use. This association is typically interpreted causally: peers who drink incite their friends to drink. This association may be complicated by uncontrolled genetic and environmental confounds because teens with familial predispositions for adolescent substance use may be more likely to select into social networks where drinking is common. We test this alternative hypothesis using a sample of 1,820 twin and sibling pairs, and their same-sex best friends, from three waves of the National Longitudinal Study of Adolescent Health. Across all three waves, peer report of substance use did not influence adolescent alcohol use when genetic and shared environmental predispositions for drinking were considered. The association between alcohol use and peer behavior may be a spurious association attributable to a shared genetic liability to drink alcohol and associate with peers who drink alcohol.

Preschool Behavioral and Emotional Rating Scale (PreBERS): Test–Retest Reliability and Inter-Rater Reliability

The Preschool Behavioral and Emotional Rating Scale (PreBERS) is a standardized, norm-referenced instrument that assesses the emotional and behavioral strengths of preschool children. Two studies that investigated the test–retest and inter-rater reliability of the PreBERS are reported. In the first study, teachers rated preschool children (N = 96) on two occasions with 1 month between ratings. Reliability coefficients for the four subscales and total score of the PreBERS were all at or above 0.86. In the second study teachers and paraprofessionals rated the same preschool children (N = 88). All of the correlations were over 0.72. In both studies the magnitude of correlations were large indicating that the PreBERS is a stable measure across time and raters. Based on the data the PreBERS appears to be a psychometrically sound instrument appropriate for use with preschool children. Recommendations for use with preschool children as well as future research are discussed.     

The Opposite of Human Enhancement: Nanotechnology and the Blind Chicken Problem

Nanotechnologies that have been linked to the possibility of enhancing cognitive capabilities of human beings might also be deployed to reduce or eliminate such capabilities in non-human vertebrate animals. A surprisingly large literature on the ethics of such disenhancement has been developed in response to the suggestion that it would be an ethically defensible response to animal suffering both in medical experimentation and in industrial livestock production. However, review of this literature illustrates the difficulty of formulating a coherent ethical debate. Well structured arguments for disenhancement can be made on the basis of mainstream views on the basis of ethical obligations to animals, but these arguments have not been persuasive against the moral intuition that disenhancements are unethical. At the same time, attempts to ground these intuitions in a coherent philosophical doctrine have been plagued by logical fallacies and question begging assertions. As such, the debate over animal disenhancement forecasts an enduring conundrum with respect to the core question of transforming the nature of sentient beings, and this conundrum is logically independent of claims that relate either to the distinctive of human beings or to issues deriving from the emphasis on enhancement.     

Mediators of behavior change in two tailored physical activity interventions for adolescent girls

ObjectivesIt has been suggested that the lack of knowledge regarding the mechanisms responsible for behavior change may be responsible for the low levels of effectiveness in physical activity interventions among youth. While it is common for physical activity interventions to cite a theoretical framework, few test the validity of their constructs using an established mediation analysis technique. The purpose of this study was to identify mediators of physical activity behavior change in two tailored interventions for adolescent girls.DesignThis study involved an experimental design.MethodsParticipants (N=161) were randomly allocated to a control (CON) group, an intervention based on the Health Promotion (HP) Model or an intervention developed from the HP Model that included two processes from the Transtheoretical Model (THP). Both interventions included school-based education sessions, individual counseling sessions, and two physical activity sessions completed with the participants' mothers. Measures were assessed prior to the intervention, at post-intervention and at a 6-month follow-up. The following constructs were included in the mediation analyses: perceived benefits, perceived barriers, self-efficacy, exposure to models, social support, interpersonal norms, planning, stimulus control, and counterconditioning.ResultsPerceived benefits, perceived barriers, self-efficacy, and commitment to planning satisfied the criteria for mediation in the THP intervention. Self-efficacy and commitment to planning were identified as mediators in the HP intervention.ConclusionThe results of this study provide evidence that both interventions were successful in increasing physical activity through changes in the theoretical constructs.     

Maternal and Paternal Depressive Symptoms as Predictors of Toddler Adjustment

In this study we explored the relation between maternal and paternal depressive symptoms and toddler adjustment in a community sample, testing direct, additive, and interactive models of parental depressive symptoms and child adjustment. Participants were 49 families with 30-month-old children. Data were collected on maternal and paternal depressive symptoms and marital quality, as well as on toddler internalizing and externalizing behavior. The data supported an additive, but not interactive, model of prediction to externalizing behavior, such that maternal and paternal symptoms each accounted for unique variance in the prediction of toddler externalizing. Models predicting toddler internalizing were not significant. Maternal reports of marital quality, but not paternal reports of marital quality, reduced the magnitude of the relation between symptoms and child externalizing when entered as a covariate. Implications for depression screening of parents are discussed.     

Sexual promiscuity & self-control: A behavior genetic explanation to an evolutionary question

Within separate academic disciplines there exist two consistent findings that have emerged. Behavior geneticists, on one hand, continue to uncover moderate to high heritability estimates for virtually every human trait measurable. Evolutionary psychologists, on the other hand, have thoroughly documented species-wide universality in various human traits, suggesting that natural (or sexual) selection may have directly favored such outcomes. The goal of the current study, then, is to explore ways in which these lines of inquiry can be united via the use of behavior genetic methodologies coupled with evolutionary thought. Additionally, we attempt to unite our findings in a framework that can both account for the existence of heritable individual differences, while also understanding the importance of species-wide characteristics.

Behavioral and Emotional Problems in Young Preschoolers: Cross-Cultural Testing of the Validity of the Child Behavior Checklist/2-3

The cross-cultural validity of the Child Behavior Checklist for Ages 2-3 (CBCL/2-3) was tested in three Dutch samples of children referred to mental health services, from the general population, and from a twin study. Six scales were derived from factor analyses and labeled Oppositional, Aggressive, and Overactive, which constituted a broadband Externalizing grouping; Withdrawn/Depressed and Anxious, which constituted a broadband Internalizing grouping; and Sleep Problems. Internal consistencies of the scales, their test-retest reliabilities, interparent agreement, discriminative power, predictive relations with problem ratings 2 years later, and relations to other instruments designed to measure general development and behavior problems were adequate, and highly comparable to psychometric properties in American samples. It was concluded that across languages and cultures behavioral/emotional problems of young preschoolers may be adequately assessed with the CBCL/2-3.
