A rejoinder to Pribram

Summary Contrary to Pribram's assertion, Köhler proposed a functional isomorphism between brain processes and phenomenal events; the sense organs are not implied in the isomorphism principle. With respect to the facts of the Köhler-Pribram collaboration reliance on the written record is recommended.     

Integration of melody and text in memory for songs

Two experiments examined whether the memory representation for songs consists of independent or integrated components (melody and text). Subjects heard a serial presentation of excerpts from largely unfamiliar folksongs, followed by a recognition test. The test required subjects to recognize songs, melodies, or texts and consisted of five types of items: (a) exact songs heard in the presentation; (b) new songs; (c) old tunes with new words; (d) new tunes with old words; and (e) old tunes with old words of a different song from the same presentation (‘mismatch songs’). Experiment 1 supported the integration hypothesis: Subjects' recognition of components was higher in exact songs (a) than in songs with familiar but mismatched components (e). Melody recognition, in particular, was near chance unless the original words were present. Experiment 2 showed that this integration of melody and text occurred also across different performance renditions of a song and that it could not be eliminated by voluntary attention to the melody.     

Emerging independence in nursing graduates: An analysis of traditional-nontraditional value patterns

The study sought to determine whether current nursing graduates value assertiveness, independence, and achievement to a greater degree than had past graduates, and whether selection or socialization might account for such a change. Scores on the Allport Vernon Lindsey Scale of Values for 55 1974 graduates of a private baccalaureate school of nursing were compared with 66 1980 graduates. Only scores on the political scale were significantly higher for the 1980 class. 1980 graduates displayed a traditional value pattern of high social and low political scores upon entering the educational program. Longitudinal comparison of scores for the 1980 class showed a significant rise in scores on the political scale; graduating scores did not differ significantly from college norms. The results suggest a rise in nontraditional values which is the result of the educational socialization process.     

Polydipsia's contribution to temporal discrimination of rats on a fixed interval schedule

This experiment concerned the contribution of polydipsia on the temporal discrimination of rats during a fixed-interval 60-sec. schedule. In this study, the timing accuracy of 12 rats which had access to water during training was compared to that of 12 rats which had no water during training. The rats were trained for 25 sessions on an FI 60-sec. schedule. In early sessions before polydipsia was fully developed, no differences existed between the timing accuracy of the water group and no-water group. As the amount of water drunk by the water group increased as the number of sessions increased, a parallel increase was noted in the timing accuracy of the water group. In the final sessions, a significant difference was found between the timing accuracy of rats in the water group and that of those in the no-water group. It was concluded that polydipsia facilitated the development of the temporal discrimination which is characteristic of a fixed-interval 60-sec. schedule.     

Taste sensitivity in infrahuman species: Use of a genetic model to test the validity of alternative measures

In a genetic analysis of PTC taste sensitivity of mice, Ss were presented tap water and a PTC solution in a two-choice situation. A preference index was used as a measure of taste sensitivity, assuming that ability to taste would lead to avoidance, i.e., negative preference. This assumption, however, lead to the rejection of seven Ss who preferred the test solution. Due to the undesirability of deleting Ss, the data were reanalyzed, using an alternative index of taste sensitivity that required no assumption concerning the hedonic quality of the test solution. Information regarding the inheritance of taste sensitivity to PTC provided the validating criterion for this measure.
