Conducted 3 experiments, using the same 8 White King pigeons in each. Ss matched to samples of red or green disks or vertical or horizontal lines. After 10 pecks (observing responses: ORs) at red or vertical samples on the center key, a peck on the red side was reinforced. A peck on the green...
Eight male albino Norway rats were trained to make one response if a signal was shorter than a criterion duration and a different response if the signal was longer than the criterion. When exposed to intermediate durations, Ss bisected the interval at the geometric mean, and the difference limen...
Exp I used 6 adult Silver King pigeons, 2 of which were experienced; Exp II employed 28 Ss, 11 of which were experienced. Ss were trained to discriminate between 2 colors and 2 line orientations, then were transferred to a compound-stimulus discrimination in which elements from 1 dimension were...
Two experiments used a total of 100 male albino Sprague-Dawley rats. In Exp I, Ss that had wheel-turn escape training prior to inescapable shock in a restraining tube showed enhanced FR-2 shuttlebox acquisition relative to Ss not given wheel training. This "immunization" effect was not found to...
Acquisition and maintenance of autoshaped keypecking by pigeons were studied as a function of the duration of trial and intertrial intervals (ITIs). A total of 200 White Carneaux Ss were used in 2 experiments. In Exp I, trial durations were fixed and intertrial durations were variable. 25 groups...
Three experiments used a total of 122 male Sprague-Dawley rats. Ss receiving 2 exposures to a casein hydrolysate flavor, the 1st either 45 min, 2 hrs, or 4 hrs before and the 2nd 30 min before lithium-induced toxicosis, learned a lesser aversion than those receiving only the latter of the 2...
Three experiments carried out 2nd-order Pavlovian conditioning using either similar or dissimilar 1st- and 2nd-order stimuli. Exps I and II (32 Ss in each) used male Sprague-Dawley rats in a conditioned suppression and an appetitive conditioning preparation, respectively. Exp III used 16 White...
