Assessed the effects of handedness and eye-dominance on the right-left placement of human figure drawings. Previous studies had reported that right-left placement varied as a function of personality. However, the present findings indicate no significant relationship between the two personality variables in the Thorndike Dimension of Temperament Scale and drawing placement. However, left-right placement did vary significantly as a function of handedness but not eye-dominance. Although all subjects tended to place their drawings left-of-center, right-handed subjects were significantly more extreme in their placement than were left-handed subjects.
The ability of electrophotographic techniques to differentiate levels of state anxiety and state depression were investigated. Forty male and female undergraduate students, who were screened with the DACL, STAI, and Mini-Mult and who met certain dietary and medicinal restrictions, had the index finger of their left hand electrophotographed. In addition, the skin resistance level of these subjects was assessed. The discharge patterns produced by these electrophotographs were rated by two volunteer judges using a seven-point scoring system. The differences in discharge pattern ratings and skin resistance levels between high and low anxious subjects were significant, with high anxious subjects having lower-rated discharge patterns and higher skin resistance levels. No significant differences were obtained with either measure for the depression variable or the interaction effect. Interestingly, there was no significant relationship between skin resistance and discharge ratings. Regression analyses indicated that each measure accounted for unique sources of variance, with skin resistance being the best predictor of anxiety.
The effect of vibrissae amputation on completion of a learned food-acquisition excursion was tested. The mice were trained to pass from a startbox through a tunnel to a food box. The vibrissae of one group were amputated, and the running time of that group was compared to the times of three control groups. The difference in running times between groups was not significant, indicating that vibrissae removal in mice does not significantly inhibit performance of a function vital to survival.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
