A two-eye visual environment is used in training a network of BCM neurons. We study the effect of misalignment between the synaptic density functions from the two eyes, on the formation of orientation selectivity and ocular dominance in a lateral inhibition network. The visual environment we use is composed of natural images. We show that for the BCM rule a natural image environment with binocu...

knowledge-based firms play a critical role in economics of developing countries. innovation and entrepreneurship are two important factors for sustainable development of these firms. corporate entrepreneurship and recognizing factors impacting them have become important in recent years. the purpose of this paper is to examine the relations between corporate entrepreneurship, market orientation ...

We have combined earlier correlation-based models of striate ocular dominance and orientation preference map formation into a joint model. Cortical feature preferences are deened through patterns of synaptic connectivity to LGN cells which develop due to ring correlations of those LGN cells. Model parameters include spatial correlation patterns between ON-and OFF-center cells in separate eye la...

We tested 15-month-olds' capacity to represent social-dominance hierarchies with more than two agents. Our results showed that infants found it harder to memorize dominance relations that were presented in an order that hindered the incremental formation of a single structure (Study 1). These results suggest that infants attempt to build structures incrementally, relation by relation, thereby s...

The pattern formation in orientation and ocular dominance columns is one of the most investigated problems in the brain. From a known cortical structure, we build spinlike Hamiltonian models with long-range interactions of the Mexican hat type. These Hamiltonian models allow a coherent interpretation of the diverse phenomena in the visual map formation with the help of relaxation dynamics of sp...

UNLABELLED The dominance behavioral system has been conceptualized as a biologically based system comprising motivation to achieve social power and self-perceptions of power. Biological, behavioral, and social correlates of dominance motivation and self-perceived power have been related to a range of psychopathological tendencies. Preliminary evidence suggests that mania and risk for mania (man...

Two studies compared omnivores’ and veg*ns’ attitudes dehumanization tendencies toward each other identified the social psychological factors explaining them. Study 1 (N = 208, Italians) showed that hold less positive omnivores than reverse, attributed to them human uniqueness nature; these differences were explained by stronger identification with ingroup higher perceptions of reproach from ou...
