Professionals’ Reflections About the Impact of Digital Technologies on Eating Disorders

The aim of this study was to explore how professionals working with clients who suffer from eating disorders reflect the impact of digital technologies on their clients. Interviews with 30 professionals were conducted. A qualitative analysis revealed the following areas: (a) the attributes of technologies that influence people with eating disorders, (b) the characteristics of people with eating disorders that influence their interaction with digital technologies, (c) the risks of technology usage, and (d) the benefits of technology usage. The results are discussed with respect to the Rodgers’s theoretical model explaining technology–eating disorder relations and the implications for practice.     

Models of child–parent attachment in attention deficit hyperactivity disorder: Links to executive functions

This study explored multiple attachment relationships and examined four conceptual models of child–mother/father attachment—monotropy, hierarchy, independence, integration—to explain executive functioning (EF) in attention deficit hyperactivity disorder (ADHD) versus typical development (TD; n = 50 each; age: M = 11.45, SD = .50). Significant ADHD versus TD differences emerged on all EF measures and on distribution into four clusters (secure attachment to both parents, neither parent, only father, only mother). For both groups, results supported two attachment models: (a) monotropy: child–mother attachment predicted all EF measures; child–father attachment predicted none and (b) integration: clusters differed significantly on all EF measures. Children with ADHD comprised ～74% of the high‐risk cluster (concordant insecure attachment, highest EF difficulties). Discussion focused on unique risk/protective roles played by each parental attachment for understanding EF in children with ADHD or TD.     

Larval antlions show a cognitive ability/hunting efficiency trade-off connected with the level of behavioural asymmetry

Recently, antlion larvae with greater behavioural asymmetry were shown to have improved learning abilities. However, a major evolutionary question that remained unanswered was why this asymmetry does not increase in all individuals during development. Here, we show that a trade-off exists between learning ability of larvae and their hunting efficiency. Larvae with greater asymmetry learn better than those with less, but the latter are better able to sense vibrational signals used to detect prey and can capture prey more quickly. Both traits, learning ability and hunting efficiency, present obvious fitness advantages; the trade-off between them may explain why behavioural asymmetry, which presumably stems from brain lateralization, is relatively rare in natural antlion populations.     

Reprogenetics,Genetic Tools and Reproductive Risk: Attitudes and Understanding Among Ethnic Groups in Israel

The present study investigated a possible relationship between the attitudes toward genetic technologies and the understanding of genetics, reproduction, and reproductive risk among Israeli Arabs and Israeli Jews. The study included 203 respondents, who answered a structured self-report questionnaire. They were recruited using a snowball method, which increased the participation of Israeli Arabs in the sample, although the sample was not representative of the Israeli population as a whole (there were more Arabs and fewer men). The respondents in this study expressed a positive attitude toward genetic technologies, but were less in favor of using genetic tools for non-medical purposes. Respondents of both groups were not knowledgeable of genetics; however, they scored higher on the items related to reproductive risk, which suggests that some awareness about genetic risk exists in both sectors of the Israeli population. Nevertheless, Israeli Arabs were less positive than Israeli Jews regarding the application of genetic tools. Moreover, although an understanding of genetics correlated positively with the attitude among Arabs, it did not affect the attitude of Jews, who remained very positive, regardless of their level of understanding. This result suggests that other social and cultural factors, besides understanding, might be at work among these two major ethnic sectors. Further studies that integrate educational, social, and cultural aspects among ethnic sectors of the population are required to improve health services and genetic counselling in Israel and in other countries.     

Can Item Format (Multiple Choice vs. Open-Ended) Account for Gender Differences in Mathematics Achievement?

The purpose of this study was to investigate differential performance of boys and girls on open-ended (OE) and multiple-choice (MC) items on the 1988 and 1991 International Assessment of Educational Progress (IAEP) mathematics test. In the 1988 mathematics assessment, a representative sample of approximately 1,000 13-year-olds in each of the six participating countries was assessed. In the 1991 mathematics assessment, a representative sample of 9- and 13-year-olds (approximately 1,650 from each age group) in some 20 participating countries was assessed. Analyses of both assessments yielded results that indicated that boys generally performed better than girls in mathematics. In the 1988 assessment, gender effects were larger on MC items than on OE items, corresponding to results of earlier studies. However, the 1991 IAEP assessment produced contrary results: gender effects tended to be larger for OE items than for MC items. These inconsistent results challenge the assertion that girls perform relatively better on OE test items, and suggest that item format alone cannot account for gender differences in mathematics performance. Further investigation of the data revealed that the inconsistent patterns of gender effects with regard to item format were related to the difficulty level of the items, regardless of item format. Correlations between item difficulty and item gender effect size were computed for age 13 in the 1988 assessment and for ages 9 and 13 in the 1991 assessment. The correlations obtained were 0.26, 0.47, and 0.53, respectively, suggesting that the more difficult the items, the better boys perform relative to girls.     

Living Under the Threat of Relocation: Spouses' Perceptions of the Threat and Coping Resources

This study examined the contribution of couples, shared perceptions of the threat of relocation, and the buffering effect of personal and marital resources in coping with stress. The study was conducted with a random sample of 95 couples in the Golan Heights region in Israel, where a unique situation exists in which families live under a threat of relocation, due to the peace negotiations between Israel and Syria. Two resources were examined: potency and marital quality Results showed that potency made the greatest contribution to coping either with demands or stress, both in couples who had similar or different future scenarios, while marital quality was found to relieve the stress only in couples who shared the same future scenarios. The average level of stress was found to be higher but not significant among couples with different future scenarios.     

A 32-society investigation of the influence of perceived economic inequality on social class stereotyping

There is a growing body of work suggesting that social class stereotypes are amplified when people perceive higher levels of economic inequality—that is, the wealthy are perceived as more competent and assertive and the poor as more incompetent and unassertive. The present study tested this prediction in 32 societies and also examines the role of wealth-based categorization in explaining this relationship. We found that people who perceived higher economic inequality were indeed more likely to consider wealth as a meaningful basis for categorization. Unexpectedly, however, higher levels of perceived inequality were associated with perceiving the wealthy as less competent and assertive and the poor as more competent and assertive. Unpacking this further, exploratory analyses showed that the observed tendency to stereotype the wealthy negatively only emerged in societies with lower social mobility and democracy and higher corruption. This points to the importance of understanding how socio-structural features that co-occur with economic inequality may shape perceptions of the wealthy and the poor.     

The emergence of personality: Dynamic foundations of individual variation

We conceptualize personality and individual variation from the perspective of dynamical systems. People’s thoughts, feelings, and predispositions for action are inherently dynamic, displaying constant change due to internal mechanisms and external forces, but over time the flow of thought and action converges on a narrow range of states—a fixed-point attractor—that provides cognitive, affective, and behavioral stability. An attractor for personal dynamics develops through two mechanisms: the synchronization of individuals’ internal states in social interaction, and the self-organization of thoughts and feelings with respect to a higher-order property (e.g., goal, self-concept). We present formal models of both processes and instantiate each in computer simulations. Discussion centers on the implications of interpersonal synchronization and self-organization dynamics for issues in personality psychology, including shared vs. non-shared environmental influences on personality development, the expression of personality in social interaction, personal stability vs. change, personal vs. situational causation, and the emergence of self-concept.     

Connection between Suicidal Ideation,Life Meaning,and Leisure Time Activities

This study is an examination of the links between adolescent suicidal ideation, life meaning, and the ways they spend their leisure time. The sample consisted of 450 students aged 15–18. Findings showed a significant negative correlation between suicidal ideation and sense of life meaning, encompassing factors such as age and gender. Adolescents with involvement in social activities demonstrated lower levels of suicidal ideation (total score), and lower levels of depression and anxiety, than the other two groups. The study discusses the research and practical implications of these findings. The findings suggest the possibility of establishing prevention, intervention, and therapy programs for adolescents based on life meaning.
