Mailing campaigns are a way to keep longitudinal survey respondents engaged. While mailings usually include a survey answer request, sometimes respondents are contacted between-waves to update contact information or simply to keep respondent contact. Research on the actual impact of these between-wave contacts on response rates is scarce. This…

Hindsight bias is the tendency to overestimate one's prior knowledge of a fact or event after learning the actual fact. Recent research has suggested that age-related differences in hindsight bias may be based on age-related differences in inhibitory control. We tested whether this explanation held for 3 cognitive processes assumed to underlie…

Unlike historical and biological topics, economic topics are seldom dealt with in documentations on television. They are to be found in consumer advice programmes or recently in so-called help formats. Advice programmes of this kind which are based on the life story of a family or an individual person have meanwhile become an integral part of all…

The aim of the present study was to examine the interplay between test anxiety (i.e. worry and emotionality) and learned helplessness in a sample of adolescents (N = 845, aged 13-17 years) in secondary schools in Germany. In accordance with the buffering hypothesis, it was hypothesised that the detrimental association between both components of…

Achieving a clear view of one's personality is a challenging but crucial developmental task during adolescence, which has enduring influences. This task might be harder if significant others see individuals differently from how the adolescents see themselves. Supporting this, the looking-glass-self theory suggests that significant others…

Cyberbullying is usually defined by utilizing offline criteria for bullying ("repetition," "power imbalance," "intent to harm"). However, this ignores the potential relevance of cyber-specific factors ("publicity," "medium," "type" [i.e., denigration]). We compared six factors, each with…

This longitudinal study aimed to differentiate between acculturative and developmental processes by (a) comparing levels and change rates in victimization among ethnic German immigrants and native German adolescents in Germany and Russian Jewish immigrants in Israel, and (b) testing whether interindividual differences in victimization among…

Adolescents from the three cultural contexts differed in…

Social development may vary depending on contextual factors, such as attending a day school or a boarding school. The present study compares students from these school types with regard to the achievement of specific social goals, perceived social support, and reported prosocial behaviour. A sample of 701 students was examined. Students from…

The present study analysed whether bullying/victimisation and related social support vary by emotional and behavioural disturbances (EBD) as well as school type. We examined 540 German adolescents with and without emotional disturbances (ED)/behavioural disturbances (BD) attending regular and special schools for students with EBD. Adolescents with…

We address how to conceptualize and measure intentional self-regulation (ISR) among adolescents from four cultures by assessing whether ISR (conceptualized by the SOC model of Selection, Optimization, and Compensation) is represented by three factors (as with adult samples) or as one "adolescence-specific" factor. A total of 4,057 14-…
