The Effects Of Cs Habituation And Duration Of The Directional Modification Of The Cardiac Response In The Guinea Pig (Cavia Procellus), Ray Charles Larson May 1971

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.


Conservatism In A Bayesian Probability Situation As A Function Of The Sex Of The Subject, Paul Frederick Miller Aug 1967

Conservatism In A Bayesian Probability Situation As A Function Of The Sex Of The Subject, Paul Frederick Miller

All Master's Theses

The present study was designed to examine whether the conservatism present in a Bayesian probability situation could be partially attributable to the sex of the subjects performing the task. The experimental design required that the subjects estimate the probabilities of occurrence of two independent events. They were then given an opportunity to revise their estimates as additional information was experimentally introduced into the situation. These estimates were compared to estimates calculated from Bayes’ theorem.
