Mexican-American Children In The Process In Acculturation, Elizabeth Ford Stone O'Neill

University of the Pacific Theses and Dissertations

The web of Mexican-American life is complex in its origins, its manifestations, and its degree of identification with or alienation from the dominant culture. A thesis of the length of this one can deal with all this complexity only in a superficial way. However, by a rather narrowly defined examination of a few children certain insights may be gained which could be used as a basis for generalization about other children of similar background, and perhaps even for some tentative generalizations about the problems of the Mexican-American community as a whole.

Affective Responses To Environmental Influences In Immature Rats, William Rudolf Brunner

University of the Pacific Theses and Dissertations

The purpose of the present investigation is to add to the growing body of knowledge about the behavioral development of rats. It is an enlargement of a study by Roberts (1966) who investigated the effects of quantitative reward shifts on the behavior of immature rats. Roberts' experiment was in turn founded on earlier experiments by Crespi (1942). These experiments tested the effect of different quantitative reward levels on the behavior of adult rats. These studies of Crespi are fundamental to the understanding of the present investigation and so are discussed below in some detail.

Crespi trained adult rats, one trail …

The Effects Of Positive And Negative Reinforcement On A Learning Task In Hospitalized Patients, Gary Robert Lancaster

University of the Pacific Theses and Dissertations

A number of writers have suggested that in comparison to normals, schizophrenics are less responsive to positive records or reinforcers (e.g., Hunt & Cofor, 1944) and overly sensitive to punishment or social censure as compared to normals (Fromm-Reichman 1954). Garmezy & Rodnick (1957) have proposed that schizophrenics are highly sensitive to any censure or disapproval, arising from their interpersonal contacts. They further say that such intolerable levels of anxiety are aroused that schizophrenics are held to be much more strongly motivated than normals to reduce the anxiety by acting to avoid or escape the censorious aspects of the situation.
