Memory for number of light flashes in the pigeon
Tóm tắt
Two groups of pigeons were trained to perform symbolic delayed matching-to-sample at a 0-sec delay with sample stimuli that consisted of sequences of light flashes. The sequences varied in number but not time for one group (number group) and in time but not number for the other group (time group). When retention was tested at delays up to 10 sec in Experiment 1, a choose-small effect was found in the number group, and a choose-long effect was found in the time group. Transfer tests between number and time samples in Experiment 2 supported the hypothesis that pigeons were discriminating between the number of light flashes at the end of sample sequences in Experiment 1. It was concluded that pigeons in both the number and the time groups were discriminating between number of flashes and that the apparent choose-long effect was actually a choose-small effect. The implications of these findings for the mode-control model of counting and timing (Meck & Church, 1983) were discussed.
