Abstract: | Attempted to differentiate behaviors of Mongolian gerbils analogous to Type A (coronary-prone) and Type B (non-coronary-prone) human behavior. Preliminary classification of 20 Ss was based on performance on differential reinforcement of low rates 20-sec and 60-sec schedules. To retain their preliminary classification, Type A and Type B Ss were required to be dominant and subordinate, respectively, in matches with Ss of opposite behavioral classification. Ss that exhibited Type A timing won significantly more dominance matches than did Type B Ss. Incidence rates of Type A and Type B behavior in the 2 selectively bred generations were significantly greater than frequencies in the original stock.
