Interpreting other people’s intentions during communication represents a remarkable challenge for children. Although many studies have examined children’s understanding of, for example, sarcasm, less is known about their interpretation. Using realistic audiovisual scenes, we invited 124 children between 8 and 12 years old to watch video clips of young adults using different speaker intentions. After watching each video clip, children answered questions about the characters and their beliefs, and the perceived friendliness of the speaker. Children’s responses reveal age and gender differences in the ability to interpret speaker belief and social intentions, especially for scenarios conveying teasing and prosocial lies. We found that the ability to infer speaker belief of prosocial lies and to interpret social intentions increases with age. Our results suggest that children at the age of 8 years already show adult-like abilities to understand literal statements, whereas the ability to infer specific social intentions, such as teasing and prosocial lies, is still developing between the age of 8 and 12 years. Moreover, girls performed better in classifying prosocial lies and sarcasm as insincere than boys. The outcomes expand our understanding of how children observe speaker intentions and suggest further research into the development of teasing and prosocial lie interpretation.

This study examined the degree to which time perspectives were associated with the processes and content of autobiographical memory. A sample of 230 young adults (118 women) completed the Zimbardo Time Perspective Inventory (ZTPI; Zimbardo and Boyd, 1999 ), the Big Five Inventory (BFI; John and Srivastava, 1999 ), and responded in writing to seven memory prompts as well as to items from the Autobiographical Memory Questionnaire (AMQ; Rubin et al., 2003 ). The Past Positive and Future subscales of the ZTPI predicted many aspects of memory even when controlling for BFI traits. There were gender differences in time perspectives and gender moderated a number of the correlations between time perspectives and autobiographical memory.

Objective: This study explored the effect of cultural and gender differences in ADHD among Spanish, African American, Hispanic American, and European American young adults. Method: Structural equivalence between the four groups was examined by Tucker’s phi coefficient. A MANCOVA was carried out with cultural groups and gender as factors and age as covariate. Results: Structural equivalence was observed across all groups, and no differential item functioning was found. No significant effect was found for gender, although, with the exception of the Hispanic group, males scored higher than females. Furthermore, small, though significant, cultural differences were found. The lowest levels of ADHD were observed in the European American group and the highest in the Hispanic American group. ADHD symptoms, notably inattention, showed some decline with age. Conclusion: Findings extend existing data and suggest a relationship between culture and the development of ADHD, which might be mediated by parenting style.

This study investigated perceptions of love across the lifespan using Sternberg’s triangular theory of love, which distinguishes between passion, intimacy, and commitment. The study aimed to (a) investigate the psychometric properties of the short Triangular Love Scale (TLS-short) in adolescents and adults (see Appendix), and (b) track age and gender differences in the three love components of the TLS-short in a sample of 12- to 88-year-olds (N = 2791). The three-factor structure of the TLS-short was confirmed in both the adolescent and adult sample. Adolescents (12–17 years) reported lower levels of all love components compared to young adults (18–30 years). Late adults (50+) reported lower levels of passion and intimacy, but similar levels of commitment compared to young (18–30 years) and middle adults (30–50 years). Gender differences in the perceptions of all three love components were present but less sizeable than suggested in popular accounts and earlier academic research.
