Anisomycin impairs long-term working memory in a delayed alternation task

A long-term temporal component of working memory of rats trained on the radial maze has been shown to be susceptible to disruption by the protein synthesis inhibitor, anisomycin. It is not clear whether protein synthesis played a role in working memory because accurate performance on the radial maze required the storage of a large amount of information, or because the information was to be held in store for relatively long periods of time. This experiment tested these hypotheses by assessing the effect of anisomycin on choice accuracy in a comparatively simple spatial delayed alternation task. Results indicate that under the present training conditions, protein involvement in working memory is related more to the length of the retention interval than to the amount of information retained.     

Outline of a denotative definition of aggression

Aggression is defined as generic assertiveness which includes both constructive and destructive behaviors. An attempt is then made to classify the distinctive operational settings (phenotypic situations) which trigger aggression. The classes of such settings are: 1) privation - the frustration of vital needs and the frustration due to inner conflict of needs; 2) conflict (social) - situation-specific competition and intragroup rivalry for dominance; and 3) victimization — predator-prey relations and vandalism per se. Critical questions which emerge from the definition and classification are posed.     

An Elementary Syllabus of Psychological Tests

The purpose of this study was to examine the universality of the “inverse square root law” insofar as it purports to show a constant relationship between emotional involvement and subjectively perceived geographical distance. It was argued that the square root exponent in the “law” was derived from experiments that used a limited range of stimuli (place names). With students as subjects, two experiments were conducted in order to discover the relationship between emotional involvement and subjective distance when both very close and very distant places were considered. It was shown that the inverse square root function was not constant but rather varied with the range of stimuli.
