Knowledge-telling and knowledge-transforming arguments in mock jurors' verdict justifications

According to the “story model” a juror constructs an implicit mental model of a story telling what happened as the basis for the verdict choice. But the explicit justification of a verdict choice could take the form of a story (knowledge telling) or the form of a relational (knowledge-transforming) argument structure that brings together diverse, non-chronologically related pieces of evidence. The study investigates whether people tend towards knowledge telling or knowledge transforming, and whether use of these argument structure types are related to skilled argument and epistemic understanding. A sample of people on jury duty chose and justified verdicts in two abridged cases. Participants tended to display the same argument structure and argument skill across cases. Those using knowledge-transforming structures were more successful at the juror argument skills task and had a higher level of epistemic understanding. The discussion suggests that jurors approach their task with an epistemic orientation towards knowledge telling or knowledge transforming.     

Birth Order Position and Prosocial Tendencies

This study investigated the relationship between psychological birth order position and different types and levels of prosocial tendencies. An ex postfacto, between-family research design was used. Data on prosocial tendencies were obtained from 888 college students (females = 80.4%, mean age = 20.94 yrs, SD = 2.83; males = 19.6%, mean age = 21.62 yrs, SD = 2.44). Participants completed a biographical questionnaire as well as the Prosocial Tendencies Measure (Carlo & Randall, 2002). Data were analysed to compare and contrast prosocial tendencies between demographics using parametric ANOVAs, t tests and the Mann-Whitney Test. Significant differences in prosocial tendency scores were only found between middle-borns and last-borns on altruism, with middle-borns scoring significantly higher in prosocial tendencies than last-borns. There is no evidence to suggest that a definitive link between prosocial tendencies and birth order exists in this study.     

School enrolment and executive functioning: A longitudinal perspective on developmental changes,the influence of learning context,and the prediction of pre-academic skills

The present two-year longitudinal study addressed developmental changes in different aspects of executive functioning (i.e., inhibition, updating, and cognitive flexibility) in a sample of 264 children aged between 5 and 7 years. Of special interest were issues of developmental progression over time, the influence of learning context and the predictive power of executive functions and school context for emerging academic skills. The results revealed pronounced improvements in all executive measures, both over time and as a function of age. For the learning context, small and age-dependent effects on executive skills were found. Inhibition uniquely contributed to the prediction of aspects of emerging academic skills, over and above chronological age and language skills.     

Promoting emotional well-being through the use of humour

Humour skills programmes are believed to assist in improving emotional well-being by increasing self-efficacy, positive thinking, optimism and perceptions of control, while decreasing negative thinking, perceptions of stress, depression, anxiety and stress. The study aims to evaluate a programme investigating this possibility. Volunteers from the community (37 females and 18 males, aged M?=?38 years) were randomly assigned to a humour group, a social group or a non-intervention control group. The programme, consisting of a manual and a booklet of measures assessing indices of well-being, was administered over an 8-week period. Data were collected at baseline, post programme and at 3-month follow-up. Results revealed that unlike the control and social groups, the humour group demonstrated a significant increase in several indices of emotional well-being. Specifically, increases occurred with self-efficacy, positive affect, optimism and perceptions of control, while decreases were found in perceived stress, depression, anxiety and stress levels.     

Abstract construals make the emotional rewards of prosocial behavior more salient

Although previous research has shown that helping others leads to higher happiness than helping oneself, people frequently predict that self-serving behavior will make them happier than prosocial behavior. Here, we explore whether abstract construal – thinking about an event from a higher level, distanced perspective – influences predictions about how rewarding prosocial actions will be for people’s own well-being. In Experiment 1, Hurricane Katrina volunteers who adopted an abstract construal predicted that their efforts would be more rewarding than did volunteers who adopted a concrete construal. Experiment 2 provided a conceptual replication with a hypothetical donation scenario; people who adopted an abstract rather than concrete construal predicted that giving more money would be more rewarding than giving less. These findings suggest that people are more likely to appreciate the emotional benefits of prosocial actions when they adopt high-level construals than when they adopt low-level construals.     

Development of Academic Skills from Preschool Through Second Grade: Family and Classroom Predictors of Developmental Trajectories

Children's experiences with their parents and teachers were related to the acquisition of academic skills from preschool through second grade. Individual and group growth curves were estimated, and individual patterns of change were predicted from selected demographic, family, and classroom characteristics to identify multiple pathways to early academic competence. Standardized assessments of language and academic skills and parent and teacher surveys were collected on 511 children beginning in the second-to-last year of child care through the third year of elementary school. As expected, children tended to show better academic skills across time if their parents had more education and reported more progressive parenting beliefs and practices. Statistical interactions between family background and teacher-child relationships indicated that a closer relationship with the teacher was positively related to language skills for African-American children and to reading competence for children whose parents reported more authoritarian attitudes. These results provide further evidence that social processes in classrooms are important for academic competence for children considered at risk for academic problems.     

Cognitive Skills as Predictor of Attitudes Toward Political Conflict: A Study of Polish Politicians

The relationship between cognitive development and attitudes toward a current political conflict was examined in a sample of 46 Polish politicians. This relationship was examined in a control group in a neutral condition and in an experimental group after participants were presented with a hostile attack on their position on the conflict. Politicians with less advanced cognitive skills tended to use competitive attitudes in both conditions. In contrast, those who possessed more advanced skills tended to use cooperative attitudes in the neutral situation; after the emotional attack, they tended to avoid further involvement in the conflict and sought to exit it. The key difference in participants' cognitive functioning was their ability to differentiate perspectives and to transcend their own point of view in the conflict.     

The Role of Autonomy Support and Autonomy Orientation in Prosocial Behavior Engagement

Two studies examined individual and environmental forces that affect engagement in prosocial behavior. Self-determination theory was used to derive a model in which autonomy orientation and autonomy support predicted satisfaction of three core psychological needs, which in turn led to engagement in prosocial activities. In Study 1, college students reported their engagement in various prosocial activities, and completed measures of autonomy orientation, parental autonomy support, and general need satisfaction. In Study 2, volunteer workers completed measures of autonomy orientation, work autonomy support and need satisfaction at work. The number of volunteered hours indicated the amount of prosocial engagement. Results across the studies showed that autonomy orientation was strongly related to engagement in prosocial behavior, while autonomy support was modestly related. Need satisfaction partially mediated the effect of autonomy orientation, and fully mediated the effect of autonomy support. Interestingly, autonomy support predicted lower volunteer turnover. Implications for how prosocial behavior can be motivated are discussed.     

The effects of reinforcement rate on the spontaneous social initiations of socially withdrawn preschoolers.

Social skills priming was used to increase the spontaneous social initiations of 2 socially withdrawn preschoolers, 1 of whom had been diagnosed with autism. During priming sessions, the teacher prompted and reinforced social behaviors (e.g., smiling, verbal initiations). We varied the rate of reinforcement during priming sessions and measured the effects of this manipulation on the rate of spontaneous social initiations during the subsequent classroom activity. Spontaneous initiations were more frequent after high rates of reinforcement than after low rates of reinforcement.     

Fundamental motor skill,physical activity,and sedentary behavior in socioeconomically disadvantaged kindergarteners

Guided by Stodden et al’s conceptual model, the main purpose of the study was to examine the relation between fundamental motor skills (FMS; locomotor and objective control skills), different intensity levels of physical activity (light PA [LPA], moderate-to-vigorous PA [MVPA], and vigorous PA[VPA]), and sedentary behavior (SB) in socioeconomically disadvantaged kindergarteners. A prospective design was used in this study and the data were collected across the 2013–2014 academic school year. Participants were 256 (129 boys; 127 girls; M_age = 5.37, SD = 0.48) kindergarteners recruited from three public schools in the southern United States. Results found that FMS were significantly related to LPA, MVPA, VPA, and SB. Regression analyses indicate that locomotor skills explained significant variance for LPA (6.4%; p < .01), MVPA (7.9%; p < .001), and VPA (5.3%; p < .01) after controlling for weight status. Mediational analysis supports the significant indirect effect of MVPA on the relation between FMS and SB (95% CI: [?0.019, ?0.006]). Adequate FMS development during early childhood may result in participating in more varied physical activities, thus leading to lower risk of obesity-related behaviors.
