Resistance To Weakening Influences As A Function Of The Similarity Between Aquisition And Weakening Phases, Harry F. Desroches

Doctoral Dissertations

In general there are three reasons for the study: (1) to test a specific hypothesis as deduced from a particular theoretical position, the generalization hypothesis, that resistance to weakening influences is a function of the similarity between acquisition and weakening phases, (2) to compare and to contrast the influences of various experimental operations in weakening a learned response, (3) to compare two groups of people who are believed to respond different to traditional methods of strengthening and weakening behaviors.

There is general agreement that much, if not most, of human behavior is learned. As the infant matures he meets new …

An Appraisal Of Psychologic Deficit In Children With Cerebral Palsy, Garret H. Yanagi

Doctoral Dissertations

It is the purpose of this study to investigate the relationship between Psychologic Deficit and the effects of brain damage and environmental experiences. It is an exploratory study, therefore concerned with descriptive, testable data which may yield hypotheses concerning cerebral palsied children.

Thus, an attempt has been made to point out various viewpoints and corresponding contradictory experimental evidence with regard to the cerebral palsied. One criticism which is inherent in many of these studies lies in the difficulty encountered in replicating them. This difficulty was seen in the lack of definition of terms, as well as of well defined groups, …

A Study Of Important Stimuli In The Lives Of Men With Lung Cancer, Landon Crocker Peoples

Doctoral Dissertations

(From the Introduction)

Except in specified instances where the etiology is known, the growth of cancerous tissue in humans is an unsolved problem (Cutler 1954). Most of the investigations in this area have been medical, physiological, or biochemical. There are, however, enough studies of a psychological nature (to be cited in a later section), with sufficiently intriguing results, to warrant further research into the possibility of a relationship between psychological variables and the incidence of human cancer. The present study is concerned with this relationship.

Extinction Following Qualitative Change In The Reinforcing Stimulus, Robert E. Taylor
