Activated charcoal updated.

Activated charcoal, commonly recommended for treatment of chemical ingestions, is the residue from destructive distillation of various organic materials treated to increase its adsorptive power. Since there are no known side effects, the dose should be sufficiently large for optimum adsorption. In the literature, the recommended doses range from 30 gm to 120 gm, or in a charcoal-drug ratio of 10:1. For maximum effect, activated charcoal should be administered within 30 minutes of ingestion. It can be given while its effectiveness for a particular toxic substance is verified.

Perceptual analysis of moving patterns.

Configurations of moving points are often perceptually analyzed into relative and common vectors that are different from the actual motions. If a movement configuration is abruptly replaced by a test point whose objective velocity continues the apparent (but illusory) course of one of the original points, observers perceive that course as uninterrupted and colinear. This finding provides a quantitative measure of the vector extraction phenomenon and was used to show that neither of the two current models adequately fits that phenomenon.

Discrimination, Psychological

Conformity to peer pressure by students with learning disabilities: a replication.

This study assessed the reported responses of junior high school students with learning disabilities and normally achieving classmates to peer pressure to conform in prosocial and antisocial activities. The results replicate those of an earlier study in finding that students with learning disabilities indicated more willingness than their classmates to conform to peer pressure to engage in antisocial actions.
