The Effect Of Priming, Christian Orthodox Beliefs, And Training On Critical Thinking, Cheryl Norry

Theses and Dissertations (Comprehensive)

This study investigated the extent to which pro and antireligious individuals responded objectively and critically to religious and nonreligious material. Proreligious (n=72) and antireligious (n=72) individuals, as determined by Fullerton and Hunsberger’s (1982) Christian Orthodoxy Scale, were selected from 507 introductory psychology students. They judged the logical soundness of 30 syllogisms (10 proreligious, 10 antireligious, and 10 neutral) following a priming task (critical, religious, or neutral). Prior to the analysis of the syllogisms, half of the subjects were given logic training, while the other half did not receive any instruction in logic. Dependent variables included critical ability (i.e., the number …

The Relationship Between Long-Term Psychiatric Clients’ Psychological Well-Being And Their Perceptions Of Housing And Social Support, Mary E. Earls

Theses and Dissertations (Comprehensive)

The present research examined whether quality of housing and quality/quantity of social support were related to long-term psychiatric clients’ perceptions of psychological well-being. The participants were 89 persons between the ages of 18 to 65, who had been hospitalized for psychiatric problems at least twice and who had been diagnosed as schizophrenic, chronic depressive, or manic-depressive. A structured interview schedule was used which incorporated measures of each of the variables. Results indicated that quality of housing was inversely correlated with Negative Affect, but unrelated to Positive Affect. Support satisfaction was negatively correlated with Negative Affect, and frequency of support was …

The Effects Of Training On The Quantification Of Uncertainty, Stephen P. Claxton-Oldfield

Theses and Dissertations (Comprehensive)

The use of intuitive heuristics has been put forward as an explanation for people’s assessment of probabilities (Kahneman & Tversky, 1972, 1973; Tversky & Kahneman, 1971, 1974). This phenomenon is seen as robust since “experts” (professional psychologists) make use of the same heuristics as “novices” (laypeople), despite having “had extensive training in statistics” (Tversky & Kahneman, 1974, p. 1130). However, replacing probability calculus with heuristics can lead to systematic errors and biases in probabilistic judgments. This study was designed to investigate the effects of statistical training on how people think about probabilistic judgments. Subjects’ knowledge base of probabilistic concepts, as …

Cerebral Asymmetries In Human Colour Perception, Zoe L. Hayes

Theses and Dissertations (Comprehensive)

Two experiments were designed in order to explore hemisphere asymmetries in both the identification and discrimination of colour. Extensive predictions were made based on the assumption that manual responses are controlled from the contralateral hemisphere and speech from the left hemisphere. The results of both experiments were inconclusive. Discussion centred around possible reasons for the limited effects and the design of future research.

Meaning Formation, Gail F. Czukar

Theses and Dissertations (Comprehensive)

An attempt was made to demonstrate laboratory conditions in which experiential components of meaning (i.e. perceptual and emotional correlates of observable stimuli and responses) pattern to form a gestalt. Semantic differential scales were used to measure the meaning of simple visual figures in two phases of the experiment. The first phase consisted of a pre- and post-exposure measurement of meaning with an intervening exposure to a compound visual display. In the second phase, subjects were exposed to an altered visual display and then rated the stimuli again.

Results do not support the predictions that (1) the meaning of the central …
