Increasing Pre-service Teachers’ Use of Differential Reinforcement: Effects of Performance Feedback on Consequences for Student Behavior

Significant dollars are spent each school year on professional development programs to improve teachers’ effectiveness in the classroom. The usefulness of these programs can be measured by the consistent application (i.e., implementation integrity) of skills which were taught in the training sessions. This study assessed the integrity with which pre-service teachers used a differential reinforcement of alternate behavior (DRA) strategy taught to them during their student teaching experience. Seven student teachers in general education settings participated. Teaching assignments ranged from early elementary through high school in urban, suburban, and rural settings. Intervention consisted of a 1-h workshop and individual feedback meetings following direct classroom observation. Results showed that (a) student teachers increased their number of correct DRA responses as measured by accurate teacher feedback to students, and (b) students showed increased hand-raising and decreased talk-outs. Implications for helping pre-service general education teachers to teach more consistently and effectively in inclusive settings are discussed.     

Self-denial and the role of intentions in the attribution of agency

The ability to distinguish between our own actions and those of an external agent is a fundamental component of normal human social interaction. Both low- and high-level mechanisms are thought to contribute to the sense of movement agency, but the contribution of each is yet to be fully understood. By applying small and incremental perturbations to realistic visual feedback of the limb, the influence of high-level action intentions and low-level motor predictive mechanisms were dissociated in two experiments. In the first, participants were induced to claim agency over movements that were subject to large perturbations and to deny agency over self-produced unperturbed movements despite the application of motor corrections by low-level mechanisms. A control experiment confirmed that if reaches met with their intended goal then they were more likely to be attributed to the agent, regardless of the discrepancy between the actual and seen positions of the limb.     

The differential involvement of the prelimbic and infralimbic cortices in response conflict affects behavioral flexibility in rats trained in a new automated strategy-switching task

To assess the role of the prelimbic (PL) and infralimbic (IL) cortices in mediating strategy switching, rats were trained in a new automated task in a Y-maze allowing a careful analysis of rats' behavior. In this situation, rats can only use two egocentric (Right, Left) and two visual (Light, Dark) strategies. In the first experiment, rats with PL, IL, or PL/IL lesions were compared with sham-operated rats when trained to reach a criterion of 10 consecutive correct responses with a light strategy before being trained with a response strategy (rule shifting), and finally with the reversed response strategy (reversal). In the second experiment, sham-operated and PL-lesioned rats had their first two strategy switches in the reverse order, which was followed by a second rule shifting and reversal. The results indicate that lesions did not affect initial acquisition, but impaired the first rule shifting and reversal. Thorough analyses of rats' performance indicate that lesioned rats were still able to demonstrate some behavioral flexibility but have difficulties in solving response conflicts, which in turn may affect behavioral flexibility. Both areas were differentially involved in the resolution of response conflict, with the IL involved in the choice of strategy previously known to be nonvalid, and the PL in the selection and maintenance of that strategy.     

On the Outcomes of Intergroup Apologies: A Review

Governments and political groups around the world are increasingly offering apologies to atone for past injustices. In recent years social psychologists have begun to empirically explore whether these apologies improve intergroup relations. We organize this literature into a framework outlining potential outcomes of intergroup apologies, mediators of those outcomes, and circumstances that allow those outcomes to be realized. Psychologists have focused most of their efforts around the questions of whether and when intergroup apologies elicit forgiveness and foster positive intergroup attitudes. Thus, in addition to outlining the present state of knowledge on intergroup apologies, this framework highlights areas that require further research; most notably, the model makes evident that we know little about what psychological states mediate intergroup apology effects.     

Liar, liar: internet faking but not frequency of use affects social skills, self-esteem, social anxiety, and aggression.

Misuse of the Internet can affect various aspects of children's social lives. It was predicted that children who misrepresent themselves on the Internet would have less well-developed social skills, lower levels of self-esteem, and higher levels of social anxiety and aggression. The frequency of Internet use was also assessed. Students aged 11-16 years were recruited for the study from classes after obtaining consent. Questionnaires included a query of Internet behaviors, the Matson Evaluation of Social Skills with Youngsters Appropriate Social Skills and Inappropriate Assertiveness subscales, Rosenberg Self-esteem Scale, and the Social Anxiety Scale for Children-Revised. It was found that children who reported the most faking behavior on the Internet (e.g., pretending to be older) had poorer social skills, lower levels of self-esteem, higher levels of social anxiety, and higher levels of aggression. Frequency of use, however, did not affect these factors in the current study.     

Not all errors are created equal: metacognition and changing answers on multiple-choice tests.

Two experiments investigated the role of metacognition in changing answers to multiple-choice, general-knowledge questions. Both experiments revealed qualitatively different errors produced by speeded responding versus confusability amongst the alternatives; revision completely corrected the former, but had no effect on the latter. Experiment 2 also demonstrated that a pretest, designed to make participants' actual experience with answer changing either positive or negative, affected the tendency to correct errors. However, this effect was not apparent in the proportion of correct responses; it was only discovered when the metacognitive component to answer changing was isolated with a Type 2 signal-detection measure of discrimination. Overall, the results suggest that future research on answer changing should more closely consider the metacognitive factors underlying answer changing, using Type 2 signal-detection theory to isolate these aspects of performance.     

The Relationship Between School-Leisure Conflict and Educational and Mental Health Indexes: A Motivational Analysis

The purpose of the present study was to test a motivational model that explains the relationship between school-leisure conflict and indicators of educational functioning and mental health using structural equation modeling with a sample of college students. Results provided support for the proposed model. Experiencing a conflict between education and leisure contexts was negatively predicted by having a self-determined motivation for school, while self-determined motivation for leisure activities was unrelated to the experience of such a conflict. A school-leisure conflict, in turn, was associated with poorer academic consequences (poor concentration at school, academic hopelessness, few intentions of pursuing in school), which were associated with higher levels of depression and low life satisfaction. Importantly, the proposed theoretical model was supported for both men and women. Results are discussed in terms of self-determination theory (Deci & Ryan, 1985, 1991, 2000) and the hierarchical model of intrinsic and extrinsic motivation (Vallerand, 1997).     

I CAN'T MAKE YOU WORSHIP ME

This paper argues that Divine Command Theory is inconsistent with the view, held by many theists, that we have a moral obligation to worship God.     

Emotional Responses to Music: Interactive Effects of Mode,Texture, and Tempo

Although much research has explored emotional responses to music using single musical elements, none has explored the interactive effects of mode, texture, and tempo in a single experiment. To this end, a 2 (mode: major vs. minor) × 2 (texture: nonharmonized vs. harmonized) × 3 (tempo: 72, 108, 144 beats per min) within-participants experimental design was employed, in which 177 college students rated four, brief musical phrases on continuous happy-sad scales. Major keys, nonharmonized melodies, and faster tempos were associated with happier responses, whereas their respective opposites were associated with sadder responses. These effects were also interactive, such that the typically positive association between tempo and happiness was inverted among minor, nonharmonized phrases. Some of these effects were moderated by the gender and amount of musical experience of participants. A principal components analysis of responses to the stimuli revealed one negatively and one positively valenced factor of emotional musical stimuli.
