Computer-Assisted Consultation: Problem-Identification, David B. Lennox
Computer-Assisted Consultation: Problem-Identification, David B. Lennox
Dissertations
Three experiments were conducted to validate the effectiveness of Computer-Assisted Consultation (CAC)--a computer-based problem identification interviewing system for use in conducting school-based behavioral consultation. The specific goals of problem identification are to establish behavioral objectives and initial assessment characteristics. Experiment I functioned as a pilot which: (1) validated the need for problem identification, (2) demonstrated the general utility of CAC, and (3) provide a basis for program improvement. Experiment II provided a more rigorous analysis of CAC by comparing it with an actual problem identification interview. Two groups of three consultees each were exposed to one of two counter-balanced sequences …
The Delay-Reduction Hypothesis Of Evocative Effectiveness And Latency, James Bryant Nuzzo
The Delay-Reduction Hypothesis Of Evocative Effectiveness And Latency, James Bryant Nuzzo
Dissertations
Prior studies found that separations between latencies correlated with differential stimuli in a multiple discrete trial procedure were attenuated with increased intertrial interval durations. In this study six pigeons served as subjects in two groups. The procedure for one group was a multiple DRO-FR chain schedule (Ratio Delay group) while in the other group a multiple DRO - response-initiated delay interval chain schedule (Time Delay group) was used. Results of this study are consistent with the Delay-reduction hypothesis of evocative effectiveness which predicts that with increasing initial link durations relative terminal link evocative effectiveness would decrease. Specifically, relative terminal link …
Stimulus-Reinforcer And Response-Reinforcer Relationships In The Determination Of Response Latency, Bruce Edward Hesse
Stimulus-Reinforcer And Response-Reinforcer Relationships In The Determination Of Response Latency, Bruce Edward Hesse
Dissertations
Response latency is measured from the onset of a stimulus to the onset of a response and is relevant to both respondent and operant control procedures. Previous research has shown response latency to be a sensitive operant dependent variable but the contribution of respondent influences was not known. The present experiment used pigeons, a two-key procedure and a two component FR schedule to study the respondent (stimulus-reinforcer) contributions to the determination of an ostensibly operant response latency. Stimuli associated with each FR component were displayed on one key (stimulus key) while responding for reinforcement was required on a second key …
Effects Of Tripelennamine And Pentazocine Alone And In Combination On Schedule-Controlled Performance, Deborah Lou Grossett
Effects Of Tripelennamine And Pentazocine Alone And In Combination On Schedule-Controlled Performance, Deborah Lou Grossett
Dissertations
The effects of tripelennamine (3, 6, 12, 18, and 24 mg/kg) and pentazocine (5, 10, 20, 30, and 40 mg/kg), given alone and in selected combinations, were determined in rats performing under fixed-ratio 30 and interresponse-time-greater-than-15-second schedules of food delivery. When given alone, tripelennamine and pentazocine produced statistically significant decreases in responding under the fixed-ratio 30 schedule, but did not significantly affect responding under the interresponse-time-greater-than-15-second schedule. Each drug alone significantly decreased the number of reinforcers (food pellets) earned relative to control values under both schedules. The effects of the two drugs in combination were supra-additive. That is, the effects …
Effects Of Anticonvulsant Drugs On Learning And Memory, Mitchell Jon Picker
Effects Of Anticonvulsant Drugs On Learning And Memory, Mitchell Jon Picker
Dissertations
The effects of phenobarbital, clonazepam, valproic acid, phenytoin, and ethosuximide were examined in pigeons performing under repeated acquisition of response chains and delayed matching-to-sample procedures. In experiment I, clonazepam, valproic acid, ethosuximide, and phenytoin produced generally dose-dependent increases in rate of responding, while phenobarbital had little consistent effect on response rate across the dose range studied. Phenobarbital and clonazepam produced dose-dependent increases in error rates (i.e., learning impairment). Although valproic acid and phenytoin generally increased error rates relative to control values, this effect was not directly dose-dependent or consistent across subjects. In contrast to the other anticonvulsants examined, ethosuximide had …
