This study analyzes the effects of individual achievement and achievement level of student reference group on test anxiety in a national sample of 769 gifted Israeli students (grade levels 4-9), which was previously investigated by Zeidner and Schleyer (1999a). We hypothesized that when controlling for individual achievement, students' experiences of test anxiety should increase with the increa...

In men, high levels of endogenous testosterone (T) seem to encourage behavior intended to dominate--to enhance one's status over--other people. Sometimes dominant behavior is aggressive, its apparent intent being to inflict harm on another person, but often dominance is expressed nonaggressively. Sometimes dominant behavior takes the form of antisocial behavior, including rebellion against auth...

We surveyed well-acquainted dyads about two key moral character traits (Honesty-Humility, Guilt Proneness), as well as several other individual differences. We examined self-other agreement, similarity, assumed similarity, and similarity-free agreement (i.e., self-other agreement controlling for similarity and assumed similarity). Participants projected their own level of moral character onto t...

It is suggested that a moving canonical particle interacts with a vacuum regarded as a ”soft” cellular space. The interaction results into the emergence of elementary excitations of space – inertons – surrounding the particle. It is assumed that such a motion leads not only to the spatial oscillation of the particle along a path but to the oscillation of the particle centre-of-mass as well. Thi...

previous studies involving the ideal observer, the task considered has been that detection where it is assumed that there is complete a priori knowledge of the and of the possible object's shape, amplitude, and position. It is shown that the detection task to include the possibility of an unknown, slowly varying back._ _ ground reduces the importance of the low-frequency components in the image...

In order to perform at the highest level in educational settings (e.g., students in testing situations), individuals often have to control their impulses or desires (e.g., to study for an upcoming test or to prepare a course instead of spending time with the peer group). Previous research suggests that the ability to exert self-control is an important predictor of performance and behavior in ed...

We study the conversion of neutron matter into strange matter as a detonation wave. The detonation is assumed to originate from a central region in a spherically symmetric background of neutrons with a varying radial density distribution. We present self-similar solutions for the propagation of detonation in static and collapsing backgrounds of neutron matter. The solutions are obtained in the ...
