The study examined the relationship between impulsivity and field-dependence in 44 prelingually deaf and 29 hearing males (6-15 years old). Impulsivity was assessed via the Matching Familiar Figures Tests, planning ability was assessed using the Porteus Maze Test Quotient, and field dependence was evaluated on the Children's Embedded Figures Test or the Embedded Figures Test (depending on S's age). Findings supported previous research suggesting that deaf Ss are more impulsive than hearing Ss. The best predictors of impulsivity were planning ability, age, and hearing status. Field dependence was also of value as a predictor when planning ability was removed from the analysis. Statistically significant differences in field dependence were found between deaf and hearing Ss as well as between impulsivity and field dependence within each group. Results suggest that deaf and hearing Ss may be impulsive for different reasons. (CL)
