Proactive Effects in Pigeons' Memory for Event Duration: Evidence for Analogical Retention
An intrairial proactive interference design was used to examine the nature of pigeons' memory for duration in a delayed matching task. Short (2 s) or long (10 s) target samples were preceded on test trials by a short or long presample. The durations were consistent on some trials (shortshort or long-long) and inconsistent on others (short-long or long-short). Contrary to predictions based on pr...
متن کاملTiming in pigeons: effects of the similarity between intertrial interval and gap in a timing signal.
Previous research suggests that when a fixed interval is interrupted (known as the gap procedure), pigeons tend to reset memory and start timing from 0 after the gap. However, because the ambient conditions of the gap typically have been the same as during the intertrial interval (ITI), ambiguity may have resulted. In the present experiment, the authors found that when ambient conditions during...
متن کاملThe effect of intertrial interval food presentions on pigeons' delayed matching to sample accuracy.
Parallel effects of temporal variables on autoshaping and on delayed matching to sample performance suggest that delayed matching, like autoshaping, might depend upon the within-trial expectancy of reinforcement relative to the overall expectancy of reinforcement in the session. This possibility was assessed by presenting free food at different times during a 30-sec intertrial interval (ITI) in...
متن کاملSupport for a theory of memory for event duration must distinguish between test-trial ambiguity and actual memory loss.
Staddon and Higa's (1999) trace-strength theory of timing and memory for event duration can account for pigeons' bias to "choose short" when retention intervals are introduced and to "choose long" when, following training with a fixed retention interval, retention intervals are shortened. However, it does not account for the failure of pigeons to choose short when the intertrial interval is dis...
متن کاملProcedural Determinants of Coding Processes in Pigeons' Memory for Duration
Pigeon’s retention functions for duration samples differ qualitatively in choice and successive delayed-matching-to-sample tasks. This research tested procedures designed to be hybrids of these tasks. In Experiment 1, adding a fixed-interval component to the test phase of the choice procedure did not eliminate the ‘‘respond-short’’ effect that is characteristic of retention functions for durati...
