Periodic Response-Reinforcer Contiguity: Temporal Control But Not As We Know It!, Michael Keenan
Periodic Response-Reinforcer Contiguity: Temporal Control But Not As We Know It!, Michael Keenan
The Psychological Record
Two experiments using rats show the effects of introducing response-reinforcer contiguity on a modified recycling conjunctive fixed-time 30 s fixed-ratio 1 schedule of food reinforcement. In Experiment 1, the frequency of programmed contiguity was varied across conditions. The general finding was an increase in overall rate of responding for all rats when the incidence of obtained contiguity was relatively high. This increase in responding was accompanied by unusual response patterns for some rats. These patterns persisted when the rats were subsequently exposed to a fixed-interval schedule. Other rats produced fixed-interval-like performance when the incidence of obtained contiguity increased. Similar findings …

Decrease Of Precurrent Behavior As Training Increases: Effects Of Task Complexity, Jorge M. Oliveira-Castro, Domingos S. Coelho, Gardênia A. Oliveira-Castro
The Psychological Record
When someone is described as memorizing a phone number, part of what is being asserted is that the person is capable of dialing the number without looking it up in the directory. Such responses, which may decrease and stop occurring as training increases, can be interpreted as nonrequired precurrent behavior. In different experiments, participants could look up an auxiliary screen to see the numbers (Experiment 1) or arbitrary characters (Experiment 3) corresponding to different shapes. In Experiment 2, a typing task with a covered keyboard was used, in which participants could look up an auxiliary screen to see key positions. …
