The High Relief Finger Maze for Human Learning

Albino rats in independent studies were administered varying dosages of diazepam and methylphenidate prior to a daily shock traumatization experience in infancy. All animals were tested on avoidance conditioning in adulthood. Both drugs were found to be effective in modifying the typically obtained shock deficit. The results failed to substantiate that increased dosage level resulted in more effective modification of trauma effects. Delayed consequences of methylphenidate administration included modification of central nervous system reactivity as manifested in quicker reaction times and growth depression as manifested in lessened body weights in this group in comparison to the diazepam group. An additional feature of the study was the finding that male and female animals responded differently to the drug and shock experiences.     

Unidirectional Mazes for Studying Human Learning

The purpose of this study was to determine if academic performance affects locus of control scores. Twenty-one college students were randomly assigned to either a treatment or control group by sex. The treatment group received mnemonic training enabling them to score better than the control group. The treatment group had significantly more internal scores than the control group with the Rotter Locus of Control Scale but not with the Nowicki-Strickland I-E Scale.
