with different cues (AX, BX). The trials are arranged so that the correlation of cues A and B with the outcome is either perfect (e.g., AX+/BX-) or imperfect (AX+/AX-/BX+/ BX-), while the relationship of X with the outcome is the same in each condition. The animals are subsequently tested with X. Cue X elicits greater conditioned responding in. Also, pigeons can make relative numerosity judgments even when the arrays consist of entirely novel numbers of dots, as Emmerton et al. () showed in the study of serial ordering effects. In that case, the birds had no opportunity to learn about the patterns that 3, 4 or 5 dots can form. After responding to each element in varying, successive numerosity displays, pigeons (Columba livia) had to choose, out of an array of symbols, the symbol designated to correspond to the preceding. One potential cue that might be particularly salient in the present study is control by stimulus change. In the present study (as well as Bruce et al., , and Prichard et al., ), the sample.
Homing pigeons are able to use time as a discriminative cue, either at short intervals (i.e., seconds, minutes) or long intervals (i.e., hours, days) in operant chambers (Wilkie & Willson Across three experiments, we examined the cuing properties of metric (distance and direction) and nonmetric (lighting) cues in different tasks. In Experiment 1, rats were trained on a response problem in a T-maze, followed by four reversals. Rats that experienced a change in maze orientation (Direction group) or a change in the length of the start arm (Distance group) across reversals showed.

A rat is trained to press a lever for a small amount of food. While pressing the lever at a steady rate, the rat is presented with a tone stimulus that had been previously paired with foot-shock. When the tone stimulus is presented by itself, the rat decreases its rate of lever pressing. This decrease is an example of.
Rats appear to time and sum the duration of successive events rather than use an event switch to “count” them. A number of previous studies have also noted the importance of temporal cues in the discrimination of event sequences (Breukelaar and Dalrymple-Alford, , Davis, , Davis and Memmott, , Fetterman, , Santi and Van. Ginsburg () found pigeons made sig- nificantly fewer errors on 0ddit.y than on similarity. He suggests that his use of observing response and correction techniques, avoided here, could differentially facilit,ate oddity compared to similarity. Wodinsky and Bitterman ()) in a st,udy with the rat. A rat is placed in a straight-alley runway and learns to rapidly traverse the alley to obtain a food reinforcer. This task a. uses a discrete trials procedure. b. uses a free-operant procedure. c. does not involve operant conditioning because the rat does not have to do anything to obtain the reinforcer. d. can be used to study the rate of.
