The purpose of this study was to determine whether gender- and age-related differences in ankle joint complex (AJC) range of motion (ROM) exist in children (range 9–13 years), adolescents (14–16 years), and young adults (17–20 years), and to compare these data with those published for older subjects (21–79 years) using the same protocol. 15 A total of 120 subjects (58 males and 62 females) ranging in age from 9 to 20 years were tested for AJC ROM using a specifically designed 6° of freedom fixture. 1 All measurements were made with respect to a laboratory coordinate system, and represented assessment of active AJC ROM. Angular displacements for plan-tarflexion, dorsiflexion, inversion, eversion, abduction, and adduction were digitally recorded and compared. AJC ROMs of females aged 9 to 20 years were generally greater than those for males about all three orthogonal axes. Within each gender, there was a consistent trend for AJC ROM to decrease from a maximum at 14 to 16 or 17 to 20 years to a minimum after age 60 years. The average decrement was greater for females than for males. This study provided evidence to support the contention that age-related and gender differences in AJC ROM do exist. The possibility of minimizing the decline in AJC ROM with age requires further investigation.

Gender- and age-related differences in the variability of various human attributes and abilities have been investigated. This article investigates the age and gender differences in the variability of Holland’s six vocational dimensions with a sample including 1,519 participants, divided into four age groups: early adolescence (12–15 years old), adolescence (16–20 years old), young adulthood (21–30 years old), and adulthood (31–59 years old). The results showed nontrivial differences in the variability of vocational interests across gender and age groups alike. Although significant differences in variability were observed for all vocational interest dimensions except investigative, the most pronounced differences in variability across age and gender were observed for realistic and conventional dimensions. Generally, the observed differences in variability were larger in adolescence than in adulthood. Overall, vocational interests displayed less differentiation within the younger age groups (early adolescence and early adulthood) as compared to adulthood.

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.

A tanulmány a Pán Péter Szindrómát, valamint a Kapunyitási Pánikot, az utóbbi évtized közkedvelt kifejezéseit és jelenségeit vizsgálja a felnőttkorba lépő, szakképzésből kikerülő fiatalok körében. Központi kérdései: Miért alakulhatott ki? Miért most? Létezik e valóban, vagy csak az elkerülési stratégiák egyik válfajáról van szó? Milyen jelenségek együttese okozza a kialakulását? Vannak- e életkori sajátosságok, amik hajlamosító tényezőkké válhatnak? Vannak-e nemi különbségek a jelenség megjelenésénél? A kérdések megválaszolásával próbálom igazolni, hogy Pán Péter szindróma helyett inkább egy speciális, életciklus váltás okozta krízis állapotról beszélhetünk. Kulcsszavak: Pán Péter szindróma, kapunyitási pánik, krízisállapot, quaterlife crisis, fiatalok, posztadoleszcencia, emerging adulthood, korszakváltás, identitás státusz, szorongás, elkerülési stratégia, depresszió Diszciplina: pszichológia, szociológia, neveléstudomány The study examines the Peter Pan Syndrome and the Quarterlife Crisis, two well-known phenomena which occur among young adults finishing their vocational training.The key questions are: Why do they happen? Why at this time? Do they really exist or are they just some types of avoidance strategies? What circumstances cause their emergence? Are there any age-related factors that may predispose their occurrence? Are there any gender differences in their appearance?Answering these questions I have come to the conclusion that instead of the Peter Pan Syndrome what we face is rather a special state of crisis caused by the life cycle transition. Keywords: Peter Pan Syndrome, quaterlife crisis, crisis status, young adults, post-adolescent, emerging adulthood, identity status, anxiety, avoidance strategy, depressionDisciplines: psychology, sociology, pedagogy

This study investigates the relationship between discrimination and mental health in aging transgender adults. Survey responses from 61 transgender adults above 50 ( Mage = 57.7, SD = 5.8; 77.1% male-to-female; 78.7% White non-Hispanic) were analyzed. Multivariable logistic regression models examined the relationship between gender- and age-related discrimination, number of everyday discrimination experiences, and past-week depressive distress, adjusting for social support, sociodemographics, and other forms of discrimination. The most commonly attributed reasons for experiencing discrimination were related to gender (80.3%) and age (34.4%). More than half of participants (55.5%) met criteria for past-week depressive distress. In an adjusted multivariable model, gender-related discrimination and a greater number of everyday discrimination experiences were associated with increased odds of past-week depressive distress. Additional research is needed to understand the effects of aging and gender identity on depressive symptoms and develop interventions to safeguard the mental health of this vulnerable aging population.

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.
