The purpose of this project was to evaluate from the student point of view the feasibility and desirability of self-awareness testing for first year School of Social Work students. Originally, the authors had hoped to arrange and evaluate mental well-being interviews for a significant sampling of students, using as a model the voluntary, private, completely confidential interviews that were conducted at McGill University's School of Social Work during 1961-1963. However, the task of funding offcampus professional interviews proved insurmountable. Therefore, the authors turned to objective personality testing with individual interpretive interviews conducted by counselors at Portland State University's Counseling Center.

The purpose of this study was to investigate the effects of increased intensity on the bone conducted speech discrimination ability of normal listeners utilizing standard audiological equipment. The NU-6 word lists were utilized to test the bone conducted speech discrimination skills of ten normal hearing subjects, 21 to 30 years of age, on standard clinical equipment. Both the hearing levels (dB HL) and the sensation levels (dB SL) of the test administration were considered. In general, it was recommended that 100 dB Hl is the most appropriate dial setting for the administration of bone conducted speech discrimination tests even though comparable speech discrimination scores may be obtained with a 95 dB HL dial setting. This study indicates that the most appropriate sensation levels for the administration of bone conducted speech discrimination tests are 55 and 60 dB SL. Most normal listeners can be expected to achieve a 55 dB sensation level at the limits of the speech audiometer (100 dB HL). Additionally, it was found that when bone conducted speech discrimination tests are administered at levels of less than 55 dB SL, the results may be compromised by variances that occurred in this normal hearing sample. Therefore, the clinical audiologist should accept bone conducted speech discrimination results as valid only when the scores obtained at 40, 45 and 50 dB sensation levels are within the limits of clinical normality (90% or better). Recommendations for further research are discussed.

This research proposed to determine, in the context of preliminary data analysis, whether one can generate more--and more complex--"insights" (meaningful or possibly relevant relationships suggested by the data) by looking at a graphic (multiple bar chart) representation--as opposed to numeric table--of a large, multivariate quantitative dataset (twenty variables with twenty four observations each), displayed and manipulated h interactively in a personal computer-based system. If the more complex observations made possible by graphic representations can be explored in more detail--with further help from statistical and mathematical techniques-then the probability of achieving truly novel and useful solutions can be increased. The major issue involved is not how to communicate more effectively information to a large audience; it is rather what would stimulate deeper, sharper, and more expeditious analysis of a problem. An experiment--of a "posttest only control group" design--was conducted, with eighty Subjects. Half of those Subjects were randomly assigned to a treatment group (graphic representation of a quantitative dataset) and the other half, to a control group (multivariate representation of same dataset). Individual experimental sessions took approximately two hours, with an interactive tutorial--designed to give both groups the same level of basic skills for handling the computer program--followed by sixty minutes (maximum) for problem analysis. The null hypothesis was there would be no differences between the scores of Subjects looking at a graphic versus a numeric representation of data for each of four classes of "insight" generation: 1 "Insights" ignoring complexity levels 2 Multiple-field "insights", exclusive of single-field "insights" 3 Multiple "field-group" (such as age groups) "insights" 4 Number of different complexity levels A methodology was developed for objective scoring of the raw data (written notes with requested observations and inferences). Observations were eliminated on the basis of repetition, incompleteness, and lack of validation from underlying dataset. The differences between "insights" produced by the "graphic" and “numeric" groups were statistically significant. The major differences corresponded to the higher levels of "insight" complexity-—those observations relative to a large number of problem variables or to the whole dataset. The "graphic“ group produced a significantly larger number of such observations. / Ph. D. / incomplete_metadata

Family functioning has been an important part of adolescent self-image formation, according to many family therapy theorists. The aspects of family functioning that are the most positive in influencing self-image formation have not been specifically diagnosed, particularly as they apply to adoptive and foster families. The present research tied together family adaptability, cohesion, and communication from the Circumplex Model with self-image and analyzed the effect these aspects of family functioning had on a subjective measure of self-image as reported by the adolescent. The sense of family satisfaction that the adolescent had was also measured, and it was compared with the self-image of the adolescent as was the number of previous foster care placements for those adolescents who had been in foster care prior to adoption or who were presently in foster care. Fifty-five adolescents (12 adoptees, 18 in foster care, and 25 living with their biological families) were administered the Offer Self-Image Questionnaire, FACES III and the Parent-Adolescent Communication Scale. Hypotheses included: (a) adolescents across the three family types who were rated as extreme or mid-range on the cohesion and adaptability aspects of the Circumplex Model would have lower self-image scores than those who were rated as balanced; (b) adolescents who achieved a higher family satisfaction score (distance from the center of the Circumplex Model) would have a higher self-image score than those with a lower family satisfaction score; (c) adolescents who report higher levels of mother and father communication will have higher self-image scores than those with lower levels of communication; (d) adolescents with two or fewer foster care placements would have higher self-image scores than those with three or more placements. Statistical significance was found when the mother communication was divided into high and low categories and compared in an analysis of variance across the three family groupings. Perceived family cohesion was also found to be statistically significant in an analysis of variance across the three family groupings, and the interaction of family type by family cohesion (balanced, mid-range, or extrane) across the groupings was also statistically significant. The other variables related to family functioning did not prove to be statistically significant. / Ph. D.

Eight-letter upper case arrays containing vertically symmetrical (VS), e.g., A-T-U-W, horizontally symmetrical (HS), e.g., B-D-C-E, doubly symmetrical (DS), e.g., H-I-O-X, and non-symmetrical (NS), e.g., F-G-L-R, were tachistoscopically exposed bilaterally for 50 ms. to fifteen male and fifteen female undergraduates. The number of letters correctly recognized for each classification condition was used as the criterion measure. A fixed, two-factor design with the second factor being repeated was analyzed using a repeated measures analysis of variance. Consequent to testing Null Hypothesis 1 (that there is no difference between the classification conditions), a check was made for the presence of a significant interaction between gender and classification condition (Null Hypothesis 2). Because Null Hypothesis 1 was rejected and there was no interaction present, the classification group means were tested using a post hoc multiple comparison procedure identified as Tukey's Honestly Significant Difference (HSD) test. Test statistics for the Tukey HSD contrasts found that significantly more VS letters were reported than DS, HS, and NS letters. Significantly more DS letters were reported than HS and NS letters. No difference in report accuracy was found between HS and NS letters. This is in sharp contrast to studies that count only responses reported in the same left-to-right order as the tachistoscopic presentation, i.e., order of report. Previous studies using an order of report method found vertically asymmetrical letters to be reported more accurately than vertically symmetrical ones. The present study disregarded order of from an order of report. It was emphasized that the subject maintain focus on the fixation dot and not attempt to scan the letter-array pattern in a left-to-right direction, as the lettersdid not have to be reported in their respective positions. A different explanation for the Harcum (1964) directionality and Bryden (1968) masking interpretations follows from an order of report method activating additional processing mechanisms such as working memory that are ordinarily not needed to process letter features.Results obtained by the present study are discussed in terms of a reversal of spatial information for touch, kinesthesis, and sound to match the brain’s reversed retino-cortical projection. / Department of Educational Psychology
