Limits Of Sensitivity To Delayed Timeout From Avoidance, Chad Michael Galuska
Limits Of Sensitivity To Delayed Timeout From Avoidance, Chad Michael Galuska
Graduate Theses, Dissertations, and Problem Reports
Session-reduction procedures have been employed to assess molar control of avoidance responding. By conceptualizing session reduction as a delayed timeout from avoidance, the present study investigated the limits of molar control while minimizing several methodological limitations inherent in such procedures. Six times during each session, a two-link chain schedule was superimposed on a baseline schedule of variable-cycle shock avoidance. Completion of the initial link (fixed-ratio 10 schedule) produced a timeout following a signaled delay during which the avoidance schedule remained operative. For most rats, the delay was manipulated across conditions from 0 s to 60 s. Control by the delayed …
Effects Of Reinforcement History For Following Rules On Sensitivity To Contingencies Of Reinforcement, Carolina Aguilera
Effects Of Reinforcement History For Following Rules On Sensitivity To Contingencies Of Reinforcement, Carolina Aguilera
Graduate Theses, Dissertations, and Problem Reports
The present experiment manipulated subjects' experimental history of reinforcement for following rules in order to assess sensitivity to contingency changes. Ten undergraduate students were presented with four training tasks. Half the subjects were presented with instructions that corresponded with the reinforcement contingencies for these tasks (Accurate Instructions group), while the other half was presented with instructions that did not correspond with the reinforcement contingencies (Inaccurate Instructions group). After meeting stability criteria, unsignaled changes in the contingencies of one of the tasks were made to test for sensitivity. Although the behavior of all the subjects eventually changed after contacting the changed …

Limits Of Behavioral Control By Temporally Extended Response -Reinforcer Relations, Todd Matthew Myers
Graduate Theses, Dissertations, and Problem Reports
Three experiments were performed to determine the extent to which the behavior of rats can be controlled by response-reinforcer relations that are extended in time. In Experiment 1, bonus pellets delivered at the end of the session were contingent upon a shift in choice responding within the session. Experiment 2 examined control of aggregated responses by a delayed consequence over a much shorter time period than an entire session. The reinforcing efficacy of bonus pellets was assessed using a chained-schedule procedure. The relation between aggregated responses and a delayed reinforcing consequence was assessed several times per session and with shorter …
Investigating Spelling Through Generative Instruction, Linda Ross
Investigating Spelling Through Generative Instruction, Linda Ross
Graduate Theses, Dissertations, and Problem Reports
The present study examined the components of generative instruction through the teaching of spelling rules. In Experiment 1, the effects of direct versus passive instruction and rate building versus equal-time practice were examined. Forty undergraduate students with below average spelling skills participated. Although there were better performances under passive instruction on some aspects of the posttests, and improved performance with rate-building practice on others, these results were not systematic and were contradicted by other results. The effects of rate building versus an equal amount of practice on the training and posttest application of spelling rules were examined in Experiment 2. …
