Mathematical Creativity: A Combination of Domain-general Creative and Domain-specific Mathematical Skills

Creativity is an understudied topic in elementary school mathematics research. Nevertheless, we argue that creativity plays an important role in mathematics, but that more research is needed to understand this relation. Therefore, this study aimed to investigate this relation, specifically between domain-general creativity, domain-specific mathematical creativity, and mathematical ability. Measures for these constructs were administered to 342 Dutch fourth graders. In order to examine the nature of the relation between creativity and mathematics, two competing models were tested, using Structural Equation Modeling. The results indicated that models in which general creativity and mathematical ability both predict mathematical creativity fitted the data better than models in which mathematical and general creativity predict mathematical ability. This study showed that both general creativity and mathematical ability are important to think creatively in mathematics.     

Rats (Rattus norvegicus) find occupancy of a restraint tube rewarding

Two experiments evaluated whether rats' occupancy of a restraint tube is reinforcing. In Experiment 1, each rat in the 0-min group moved freely in a chamber where a wall blocked access to a restraint tube. After 10 min the wall was removed, permitting 15 min of chamber access and tube entry. The other 2 groups were locked in the tube for 10 and 20 min respectively before release into the chamber for 15 min. Across sessions, rats locked up for 10 and 20 min entered the tube more frequently than rats in the 0-min group, and during the first 2 sessions rats in the 20-min group stayed in the tube longer than the other groups. Over sessions this difference disappeared. However, for all groups and sessions the mean percentage of session time in the tube exceeded chance expectations. This result suggests tube occupation was reinforcing. In Experiment 2’s Phase 1, rats could enter an open tube. On exiting, the tube door closed. A lever press opened the door for the rest of the 1-hr session. In Phase 2, these rats were locked in the tube for 10 min before the door opened. Upon exiting, the door closed. As in Phase 1, a lever press opened the door for the rest of the session. The latency between pressing and tube entry decreased over sessions, indicating that tube entry reinforced lever pressing. These results are difficult to reconcile with accounts of rat empathy based on the thesis that tube restraint distresses occupants.

Effect of autonomy support and dialogic learning on school children’s physical activity and sport

This study applies an intervention based on autonomy support through dialogic learning to examine effects on motivation and the promotion of physical activity and sport involvement during schoolchildren’s leisure time. One hundred and two primary school students, aged 11–13 years, participated (M = 10.93, SD = 0.75). The sample was divided into two groups: an experimental group (49 students) and a control group (53 students). A quasi-experimental study was conducted in physical education classes over the course of 9 months. Assessments of autonomy support from teachers, family, and peers; basic psychological needs; self-determined motivation in physical education and during leisure time; planned behavior variables; physical activity intention; and estimated and actual physical exercise behavior time were included in the model. Following the intervention, the results revealed that greater autonomy support by the teacher, the family and peers, satisfaction of the basic psychological needs, self-determined motivation during physical education class and during free time, greater perceived control, favorable attitude and intention to engage in physical activity contributed to the explanation of student physical activity involvement. These results suggest that when students receive extensive social support from diverse social agents that essential precursors to physical activity are strengthened and contribute to increased motivation and actual physical activity involvement. Efforts to promote effective communications with students and other pedagogical efforts, such as providing dialogic learning opportunities, should be considered in order to strengthen physical activity motivation and involvement in students.     

Denial of gender discrimination is associated with better subjective well-being among women: A system justification account

Despite the fact that women face socially and politically sanctioned disadvantages every day, a large percentage of women and men report that gender discrimination is no longer a problem. Across three studies, which together include over 20,000 participants from 23 countries, we test the hypothesis that denial (vs. acknowledgement) of gender discrimination is associated with higher subjective well-being among women (Studies 1–3), and this is because denying gender discrimination promotes the view that the system is fair (Study 1). We further show that this happens above and beyond personal experiences with sexism (Study 1) and that the association is stronger in countries where sexism is relatively high (vs. low; Study 3). We argue that denial of discrimination is an individual-level coping mechanism and that, like other self-group distancing strategies, it may perpetuate gender inequality.     

If you want to be one of us,then become like us: The evaluation of naturalization applicants by host nationals

Immigrant naturalization is a rite of passage, making assimilationist attitudes particularly pronounced among host nationals. Three experimental studies investigate whether heritage culture maintenance violates expectations that citizenship should be deserved by proving strong attachment to the host nation (i.e., neoliberal communitarianism). Study 1 (N = 293) demonstrates that naturalization applicants’ high degree of heritage culture maintenance impairs application evaluations. Perceived attachment to the host nation and citizenship deservingness mediated this effect. Study 2 (N = 220) replicates results across two national contexts and reveals that heritage culture maintenance impairs evaluations only among naturalization applicants from devalued countries. Study 3 (N = 117) manipulates attachment to the host nation and shows that perceived citizenship deservingness mediates the negative effects of naturalization applicants' low attachment to the host nation on application evaluations. Overall, assimilationist attitudes among host nationals are best explained by the combination of neoliberal and communitarian criteria of evaluation.     

Continuum between Relational and Therapeutic Models of Self-help in Mental Health: A Qualitative Approach

Self-help groups are generally described as “group[s] composed of individuals who meet on a regular basis to help one another cope with a life problem” (APA, 2019). Yet, it is challenging to find a univocal definition of self-help groups. Scholars usually use different labels to highlight various features of self-help groups, suggesting the need for further inquiry regarding commonalities and differences. The level of professional involvement is one of the most disputed factors influencing whether a group is considered to belong to the “self-help family.” The present qualitative study aimed to understand how professional support in Tuscany, Italy can influence the organizational choices of these groups (place for meetings, admission criteria, timing, etc.), as well as the personal beliefs of members. The study included 17 self-help groups. During 13 focus groups meetings, 92 participants were interviewed; then, we individually interviewed 19 facilitators and six additional key informants from mental health settings. We used a grounded theory approach, and we discussed the emerging models with participants at a public event. Results show the emergence of two theoretical models to define self-help groups, not to be interpreted as mutually exclusive. The “relational model” refers to self-help groups whose main feature is to guarantee the acquisition of specific skills (social comparison skills, active listening, and empathy), while the “therapeutic model” seems to represent a kind of assimilation of other types of interventions.
