State-Dependent Learning As A Function Of The Temporal Relationship Between Noncontingent Footshock And Electroconvulsive Shock, T. Scott Shutt
State-Dependent Learning As A Function Of The Temporal Relationship Between Noncontingent Footshock And Electroconvulsive Shock, T. Scott Shutt
All Master's Theses
Rats were given a noncontingent footshock followed at various intervals by electroconvulsive shock. Twentyfour hours later they were trained on a non-shock passive avoidance task and tested for retention 72 hours later. When the interval between NCFS and ECS was short the animals showed an amnesia which reduced as the interval was lengthened. An interval of .5 seconds produced the most pronounced amnesia and intervals greater than 10 seconds produced virtually no amnesia. The results were consistent with a state dependent retrieval failure hypothesis.
Sub-Aversive Response Contingent Foot Shock As A Positive Reinforcer, Robert Lea Fulwiler
Sub-Aversive Response Contingent Foot Shock As A Positive Reinforcer, Robert Lea Fulwiler
All Master's Theses
Forty-eight rats were divided into 8 groups; four were maintained under normal conditions and the other four under sensory deprivation and tested at o, 3, 6, and 9 days after condition institution. The response was placing the head through a hole in the operant chamber and the stimulus (0, 1.2, 4, or 12 Vac) was contingent upon the response. Analysis ot variance disclosed significant differences (p<.01) between the deprived and the non-deprived groups at days 6 and 9; and a significant interaction between deprivation condition and time of test. No differences were shown between the stimulus intensities indicating that the stimulus did not have a reinforcing effect.
The Effects Of Cs Habituation And Duration Of The Directional Modification Of The Cardiac Response In The Guinea Pig (Cavia Procellus), Ray Charles Larson
The Effects Of Cs Habituation And Duration Of The Directional Modification Of The Cardiac Response In The Guinea Pig (Cavia Procellus), Ray Charles Larson
All Master's Theses
The present experiment examined the effects of CS habituation and two different levels of CS duration (60 versus 6 sec) on the directional modification of the conditioned cardiac response in the guinea pig. The results indicated that the only reaction to the CS, regardless of prior habituation or CS duration, was a decelerative conditioned HR response. However, habituation to a CS prior to classical aversive conditioning was found to attenuate the magnitude of the bradycardia CR that developed. The bradycardia CR was discussed in terms of being a cardiac component of the orienting response.
An Assessment Of The Role Of Information Inherent In Positive And Aversive Social Reinforcement Employing A Finger Maze Task With Male And Female Subjects And Experimenters, Brian Westley Strutt
An Assessment Of The Role Of Information Inherent In Positive And Aversive Social Reinforcement Employing A Finger Maze Task With Male And Female Subjects And Experimenters, Brian Westley Strutt
Theses and Dissertations (Comprehensive)
Forty-eight male and 48 female grade 12 high school students were assigned in groups of 8 to a 2 (sex of S X 3 (treatment) X 2 (sex of E) factorial design experiment. Each S was presented with a finger maze task under one of three experimental treatments: censure-nothing with S being told “WRONG” for an incorrect response, nothing for a correct response; reward-nothing, with S being told “CORRECT” for a correct response, nothing for an incorrect response; nothing-nothing, with Ss being told nothing for either a correct or incorrect response. The task required that a binary decision be made …
Modification Of Deviant Behavior By Parents, Jeanne M. Gabourie
Modification Of Deviant Behavior By Parents, Jeanne M. Gabourie
All Master's Theses
It is the purpose of this study (1) to determine if a child's deviant social behaviors can be effectively modified by his own parents; and (2) to determine if parents can be trained to use behavior modification techniques in the home.
Shock Intensity And Task Difficulty As Determiners Of Avoidance And Escape Learning In Rats, Arthur Louis
Shock Intensity And Task Difficulty As Determiners Of Avoidance And Escape Learning In Rats, Arthur Louis
Theses and Dissertations (Comprehensive)
Thirty-six naive female hooded rats were divided randomly into three groups and tested in an instrumental escape and avoidance learning situation involving three degrees of task difficulty. Each group was also randomly subdivided into four subgroups, each of which underwent a different shock intensity level. The purpose of this study was to test the Yorkes-Dodson law which states that (a) there is an optimal level of punishment intensity for any given task (or an inverted-U curve relating shock intensity and performance) and (b) this optimal intensity decreases as task difficulty increases. The results supported (a) but not (b).
