Psychophysical experiments show that adaptation induced tilt aftereffect gets modulated under controlled conditions of attention. The underlying neurophysiological mechanisms are unknown. Here using a population model of primary visual cortex having detailed intrinsic and synaptic mechanisms we model orientation adaptation and the effect of attention. We report that increased attention to orien...

Two experiments tested the motivational synchronicity hypothesis, according to which observation of a target person’s behavior implying an intrinsic or an extrinsic motivational orientation primes the observers’ corresponding motivational orientation. Experiment 1 revealed that participants exposed to a target person intrinsically motivated to perform a task, relative to those exposed to an ext...

This study examined the relationship between dispositional achievement goal orientations and intrinsic motivation following physical fitness testing. Students, aged 11-15 years, completed the Task and Ego Orientation in Sport Questionnaire, participated in the 20-m progressive shuttle run test, and then completed a modified Intrinsic Motivation Inventory (IMI). Using their goal orientations, st...

Although it has been hypothesized that culture and religion play an important role in sexuality, the relative roles of acculturation and religiosity on ethnic differences in sexual attitudes have not been often empirically explored. The present study assessed differences in sexual attitudes in Euro-American, Asian, and Hispanic American populations using measures of acculturation to analyze the...

This study investigated determinants of active lifestyles in Singaporean university students. Using confirmatory factor analysis, a measure of lay beliefs concerning athletic ability was confirmed. Other results confirmed hypotheses that beliefs reflecting that athletic ability can be developed over time (incremental beliefs) predict an achievement task (self-referenced) orientation, while beli...

The development of both long-range intracortical and interhemispheric connections depends on visual experience. Previous experiments showed that in strabismic but not in normal cats, clustered horizontal axon projections preferentially connect cell groups activated by the same eye. This indicates that there is selective stabilization of fibers between neurons exhibiting correlated activity. Ext...

We present a qualitative positional calculus which uses oriented points as basic entities. In contrast to often-used simple points, we consider objects that have an intrinsic direction. Having an intrinsic orientation is an important property of natural objects.

Son yıllarda gençler arasında ateizm ve deizmin yaygınlaştığı, gençlerin dinden uzaklaştıkları iddia edilmekte bu konu etrafında bir takım tartışmalar yürütülmektedir. Bu tartışmaların daha sağlam zeminde yürütülmesi için alan araştırmaları ile desteklenmesi gerekmektedir. Ancak tarz araştırmalarının yapılabilmesi uygun veri toplama araçlarına ihtiyaç vardır. Türkçe literatürde ise din dışı yön...

BACKGROUND Long-term posttraumatic outcomes such as quality of life are dependent on a series of factors from the very exposure to traumatic events and stress appraisals, personality traits, posttraumatic growth, symptoms of Posttraumatic stress disorder (PTSD) and different coping strategies to religiousness and religious coping styles. Except of exposure to traumatic events and related stress...
