Imam, Abdulrazaq A.; Blanche, Justin V. – Psychological Record, 2013
In two experiments, we examined the disruptive effects of a "can't answer" response option (CARO) on equivalence formation. The first experiment was a systematic replication of Duarte, Eikeseth, Rosales-Ruiz, and Baer (1998), in which participants in a CARO group and a No-CARO group performed conditional discrimination tasks with…

Bernal-Gamboa, Rodolfo; Juarez, Yectivani; Gonzalez-Martin, Gabriela; Carranza, Rodrigo; Sanchez-Carrasco, Livia; Nieto, Javier – Psicologica: International Journal of Methodology and Experimental Psychology, 2012
Context renewal is identified when the conditioned response (CR) elicited by an extinguished conditioned stimulus (CS) reappears as a result of changing the contextual cues during the test. Two experiments were designed for testing contextual renewal in a conditioned taste aversion preparation. Experiment 1 assessed ABA and AAB context renewal,…

Holt-Hansen, Kristian – Percept Mot Skills, 1970
Presents experiments with a straight line seen for a short stimulus time in which the subjects perceived the line to lengthen from the point of fixation and then to shorten to the point of fixation immediately thereafter. (MB)

Leith, Charles R.; Maki, William S., Jr. – Journal of Experimental Psychology: Animal Behavior Processes, 1977
Whether a stimulus compound is separable or integral has predictable consequences for several human information processing tasks. The purpose of these experiments was to explore the implications of this distinction for research in animal learning and the development of learning theory. (Author/RK)

Kral, Paul A.; And Others – 1967
Investigates the effect of delay of reinforcement upon human discrimination learning with particular emphasis on the form of the gradient within the first few seconds of delay. In previous studies subjects are usually required to make an instrumental response to a stimulus, this is followed by the delay interval, and finally, the reinforcement…

Domjan, Michael; Gillan, Douglas J. – Journal of Experimental Psychology: Animal Behavior Processes, 1977
To complement investigations of the direct effects of lithium toxicosis on consummatory behavior, these experiments were designed to determine the aftereffects on drinking of exposure to a conditioned stimulus previously paired with lithium. (Author/RK)

Myers, Karyn M.; Davis, Michael – Learning & Memory, 2004
The neural mechanisms of fear suppression most commonly are studied through the use of extinction, a behavioral procedure in which a feared stimulus (i.e., one previously paired with shock) is nonreinforced repeatedly, leading to a reduction or elimination of the fear response. Although extinction is perhaps the most convenient index of fear…
