Abstract: | With a minimal intratrial interval, male golden hamsters spontaneously alternated significantly less often in a T-maze than females. Since there was no sex difference in choice latencies, the alternation difference could not be accounted for by longer intertrial intervals experienced by males. Instead, the difference was ascribed to faster rates of habituation to novelty in females because they showed greater between-sessions declines in open-field ambulation than males. From an analysis of rearing scores it was concluded that attempts to escape from the apparatus may have been the principal motivating influence in both the T-maze and open field. |
