background and objective: tamoxifen is one of the selective estrogen receptor modulators that exerts estrogen / anti-estrogen effects in various tissues. this study was done to evaluate the effect of chronic administration of tamoxifen on spatial memory and passive avoidance task in adult male wistar rats. methods: in this experimental study, 48 adult male wistar rats were randomly divided into...

electromagnetic field (emf) radiation affects cellular and brain chemistry and function, resulting in deleterious effects such as free radicals formation, impaired dna repair, reduced melatonin and blood brain barrier protection, and defects on learning and memory and other higher brain functions. in this paper the effects of low frequency emf of 50- and 217 hz, ranges often associated with com...

objective: diabetes is a metabolic disorder which impairs carbohydrate and lipid metabolism. it is accompanied by cognition impairment in diabetic patients and animal models. lipids play an important role in nerve membrane composition, structure and function. this study was designed to evaluate the effect of dietary butter and sesame oils on passive avoidance memory of streptozotocin (stz) diab...

Two studies examined the effect of status and liking of the anger target on anger behavior and individual differences in anger-related behavior. Participants recalled anger instances in which the anger target was of higher/equal/lower status and/or liked/ unfamiliar/disliked; subsequently, they indicated which behaviors they had displayed. In both studies, anger behaviors could be grouped into ...

A growing number of investigators explore evolutionary psychological hypotheses concerning the avoidance of rape using self-report measures of behavior. Among the most recent and most ambitious, is the work of McKibbin et al. (2011). McKibbin et al. presented evidence supporting their predictions that such behaviors would vary according to the individual's physical attractiveness, relationship ...

This study investigated the effect of filmed peer modeling on fear beliefs and approach-avoidance behaviors towards animals in 8- to 10-year-old typically developing children. Ninety-seven children randomly received either a positive or negative modeling film in which they saw peers interact with a novel animal. Before and after this film, children's fear beliefs and avoidance tendencies toward...

In this paper, we present a novel method for performing collective transport in the presence of obstacles. Three robots are physically connected to an object to be transported from a start to a goal location. The task is particularly challenging because the robots have a heterogeneous perception of the environment. In fact, the goal and the obstacles can be perceived only by some of the robots....
