Effects of harmonics on relative pitch discrimination in a musical context

The contribution of different harmonics to pitch salience in a musical context was examined by requiring subjects to discriminate a small (1/4 semitone) pitch change in one note of a melody that repeated in transposition. In Experiment 1, performance was superior when more harmonics were present (first five vs. fundamental alone) and when the second harmonic (of tones consisting of the first two harmonics) was in tune compared with when it was out of tune. In Experiment 2, the effects of harmonics 6 and 8, which stand in octave-equivalent simple ratios to the fundamental (2∶3 and 1∶2, respectively) were compared with harmonics 5 and 7, which stand in more complex ratios (4:5 and 4:7, respectively). When the harmonics fused into a single percept (tones consisting of harmonics 1, 2, and one of 5, 6, 7, or 8), performance was higher when harmonics 6 or 8 were present than when harmonics 5 or 7 were present. When the harmonics did not fuse into a single percept (tones consisting of the fundamental and one of 5, 6, 7, or 8), there was no effect of ratio simplicity.     

Word recognition under spatial transformation in retarded and normal readers

The recognition of words in normal, reversed, and inverted orientation was compared in a group of 9- to 11-year-old retarded readers and a matched group of normal readers. Using the ratio of reading times as an index of reading difficulty under spatial transformation, the results confirmed those of earlier studies which have shown that retarded readers' performance is less affected by spatial transformation than is normal readers'. However, an analysis in terms of the ratio of numbers of words read correctly pointed to just the opposite conclusion. The two sets of findings were reconciled by showing that they follow from the form of the function relating reading time to number correct, and by demonstrating that when word lists are equated for orthographic familiarity the performances of retarded and normal readers are equally affected by spatial transformation, whether the time or number ratio is used as an index.     

Achievement and affiliation motivation in career-oriented and homemaking-oriented college women

The purpose of this research was to investigate the possibility of an interaction between need for achievement and need for affiliation in career-oriented and homemaking-oriented college women. In the first study, scores on the appropriate scales (Achievement and Affiliation) of the Adjective Check List were obtained for 250 female college students, who were also classified as career or homemaking oriented on the basis of their responses to a questionnaire concerning postcollege plans. No significant differences were found between the career- and homemaking-oriented groups on Achievement and Affiliation; but, as predicted, a significant interaction occurred between the two variables. A second study, involving 257 college women and employing the same procedures and analysis, replicated the results of the original study: no main effects, but a significant interaction between Achievement and Affiliation. Implications of the findings for female career development and the counseling of women are discussed.     

The effect of verbal reinforcement on career choice realism

Twenty-four male undergraduates viewed 102 slides containing occupational titles and stated whether or not each represented a realistic career choice. Each subject was given three trials, with the experimental subjects receiving positive verbal reinforcement on the second trial for realistic responses. (If the choice was congruous with the individual's occupational type, as determined by the Vocational Preference Inventory, it was scored as realistic.) The results of the research revealed a tendency for all subjects to increase in career choice realism as a function of participation in the experiment, with significantly (p < .05) more experimental subjects than control subjects demonstrating an operant pattern of responses. Implications of the findings for counselors were discussed.     

A longitudinal study of an adult with aphasia: Considerations for research and therapy

This paper described investigation and therapy carried out over a one year period with an adult aphasic patient characterized by severe impairment of auditory comprehension. A deblocking technique was used to reintegrate the mechanisms for correlating sound and meaning. The visual mode of presentation of linguistic material was used both to provide a stable representation of speech units and to allow reinforcement of auditory representations. The patient was given tasks of repetition, reading aloud, and sequencing, using progressively more complex material. The behavior of the patient gives support to the viability of the theoretical constructs of linguistics: this can be seen in the differential processing of function words vs. content words, and in the orderly progression of improvement through stages explicable as the recovery of well-defined and hierarchically dependent subcomponents of linguistic organization.
