Evidence For Common Coding Of Temporal And Nontemporal Information In Pigeons, Stephen Bridson
Evidence For Common Coding Of Temporal And Nontemporal Information In Pigeons, Stephen Bridson
Theses and Dissertations (Comprehensive)
Two experiments found evidence that pigeons commonly code temporal and visual samples that are associated with the same comparisons in many-to-one matching. In Experiment 1, pigeons were trained to match temporal (2-sec and 8-sec keylight durations) and color (red and green) samples to line tilt comparisons (vertical and horizontal). Similar rates of forgetting were found for all samples. Furthermore, retention of sample information appeared more similar for samples which shared common comparisons than those that did not. In Experiment 2, pigeons learned new comparison (circle and triangle) associations with either temporal or visual samples from Experiment 1. When tested on …
Stimulus Control Exerted By Remember Cues Over Processing In Pigeons’ Short-Term Memory, Patricia E. Hernandez Torres
Stimulus Control Exerted By Remember Cues Over Processing In Pigeons’ Short-Term Memory, Patricia E. Hernandez Torres
Theses and Dissertations (Comprehensive)
The aim of the present research was to provide further evidence regarding the role of remember cues on pigeon short-term memory. The first two experiments were conducted to determine whether, using a single cuing procedure, control over delayed matching-to-sample (DMTS) performance could be demonstrated by establishing a no cue condition as an implicit cue to forget. In Experiment 1, subjects were provided with training in a procedure where both forget cue (F) and no cues indicated the omission of the comparison stimuli at the end of the delay interval. In Experiment 2, naive subjects were trained with remember (R) and …
Pigeon Short-Term Memory: The Effects Of Intertrial Interval Duration And Illumination In A Successive Delayed Matching-To-Sample Procedure, Vic Grossi
Theses and Dissertations (Comprehensive)
The aim of this research was to examine the effects of illumination and intertrial interval duration on pigeon short-term memory, using a successive matching-to-sample procedure. In phrase one the retention interval was manipulated individually for each bird. During the second phase, a correction procedure was implemented in order to reduce the number of responses made to non-match comparison stimuli. In the third phase, the birds were returned to a common baseline, in order to observe what effect elimination of the correction procedure had on the bird’s performance. In the final phase of the research, after achieving stable performance in the …
