The institutional environment of America's schools has changed substantially as government regulation has focused increasingly on the core technical work of schools--instruction. The authors explore the school administrative response to this changing environment, describing how government regulation becomes embodied in the formal structure of four…

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.…

Many authors have endorsed the hypothesis that previous emotional experiences may exert a covert influence on behavior, but some findings and replications of the original studies challenged this view. We investigated this topic by carrying out an experiment with the Iowa Gambling Task (IGT), where a dissociation procedure was adopted to…

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…

To coordinate our actions with those of others, it is crucial to not only choose an appropriate category of action but also to execute it at an appropriate timing. It is widely documented that people tend to unconsciously mimic others' behavior. The present study show that people also tend to modify their movement timing according to others'…

Thirty-eight children in first and second grade completed a 10-item rating scale on Internet use at home and school. Results suggested that, in general, more children used the Internet at school than at home but home-based use was more often perceived as enjoyable. Three patterns of Internet use emerged suggesting three types of young users:…

The purpose of this article was to explore student participation patterns in online discussion boards related to their characteristics and question types. The characteristics of students enrolled in an online course and the impact of types of discussion questions on student posts were examined. During the 16 weeks of a course, the participation…

Aim: Prader-Willi syndrome (PWS) is a genetic disorder historically characterized by two phenotypic stages. The early phenotype in infants is associated with hypotonia, poor suck, and failure to thrive. In later childhood, PWS is associated with intellectual disability, hyperphagia, as well as growth and sex hormone deficiency. Little is known…

The neurobiology of borderline personality disorder (BPD) remains unclear. Dysfunctions of several neurobiological systems, including serotoninergic, dopaminergic, and other neurotransmitter systems, have been discussed. Here we present a theory that alterations in the sensitivity of opioid receptors or the availability of endogenous opioids…

Objective: To compare the morning and afternoon/evening functioning of children with ADHD treated in the community with either atomoxetine or long-acting stimulants and reported to be doing well. Method: 109 8- to 12-year-olds and their mothers participated in one of three groups: stimulants (STIM, N = 26), atomoxetine (ATMX, N = 25), or…

Man's relationship with the environment is crucial. He can use its natural resources, but not in jest. No damaging or overuse behavior should be the dominant behavior. Religious values and rules play an important role in achieving the balance in the environment. One big goal of Islam is to make the life easy and safe. Moreover, in Islamic…
