Three experiments tested whether 12- to 24-month-old children showed systematic search, persistence, and/or end-screen search in the invisible-displacement task. A fourth study tested whether end-screen search resulted from seeing the experimenter move his hand through the series of screens. (RH)

Background: Prader-Willi syndrome (PWS) is associated with a characteristic behavioural phenotype whose main features are, alongside compulsive hyperphagia, deficits in social behaviour: social withdrawal, temper tantrums, perseverative speech and behaviour, mental rigidity, stereotyped behaviour, impulsiveness, etc. Similar symptoms may also be…

Children with developmental disabilities are slower to develop skills at intentional and symbolic communication than typically developing children, and may rely on atypical patterns of preintentional behaviors to support more complex communication development. The present study compared complex gaze engagement behaviors elicited by 25…

The main purpose of this study was to investigate and predict the behavioral intention of in-service Taiwanese kindergarten teachers regarding whether they would join a graduate level academic program. The research framework was based on the Theory of Planned Behavior (TPB) in order to identify the most influential component that affected their…

The present study developed and examined a conceptual model of working through self-defeating patterns. Participants were 390 college students at a large midwestern university. Results indicated that self-defeating patterns mediated the relations between attachment and distress. Also, self-esteem mediated the link between self-defeating patterns…

This study was designed to test the validity of a transtheoretical model's physical activity (PA) stage measure with intention and different intensities of behavior in a large population-based sample of adults living with diabetes (Type 1 diabetes, n = 697; Type 2 diabetes, n = 1,614) and examine different age groups. The overall…

Adolescence is a transitional period when the pressure to engage in romantic and sexual relationships can leave teenagers feeling confused and at risk for sexual coercion. Our studies investigated characteristics of male and female perpetrators and victims of peer sexual coercion, focusing on self-esteem, sexist attitudes, and involvement in…

Cognitive control theories attribute control to executive processes that adjust and control behavior online. Theories of automaticity attribute control to memory retrieval. In the present study, online adjustments and memory retrieval were examined, and their roles in controlling performance in the stop-signal paradigm were elucidated. There was…

The current study investigated the influence of rewards on very young children's helping behavior. After 20-month-old infants received a material reward during a treatment phase, they subsequently were less likely to engage in further helping during a test phase as compared with infants who had previously received social praise or no reward at…

The study attempts to carry out latent class analysis (LCA) in a sample of 1010 individuals, some with Attention-Deficit/Hyperactivity disorder (ADHD) and others normal. Results indicate that LCA can feasibly allow the combination of externalizing and internalizing symptoms for future tests regarding specific genetic risk factors.

The effects of parental attitudes, practices, and television mediation on adolescent sexual behaviors were investigated in a study of adolescent sexuality and media (N = 887). Confirmatory factor analyses supported an eight-factor parenting model with television mediation factors as constructs distinct from general parenting practices. Logistic…

This study examined the similarities and differences between adolescents' interactions with romantic partners and those with friends and mothers. Thirty-two adolescents were observed interacting with a romantic partner, a close friend, and their mother. Adolescents and romantic partners engaged in more conflict than adolescents and friends.…

Four studies explored the communicative behaviors of people who outperform others in a relevant or irrelevant field and the impression formed of these outperformers by the outperformed people. In line with the premises of the self-evaluation maintenance model (A. Tesser, 1988) and the STTUC framework (J. J. Exline & M. Lobel, 1999), Studies 1 and…
