APPROACH AND WITHDRAWAL IN YOUNG OF TILAPIA MOSSAMBICA (CICHLIDAE, PISCES) AS A FUNCTION OF AGE AND SOCIAL EXPERIENCE

G oude G., E dlund B., E ngqvist -E dlund U. & A nderson M. Approach and withdrawal in young of Tilapia mossambica (Cichlidae, Pisces) as a function of age and Social experience. Scand. J. Psychol ., 1972, 13 , 89–97.—In an experiment with eight groups of young of Tilapia mossambica , approach and withdrawal behavior was registered during brief (5 min) periods of stimulation with a moving dummy; the experiment lasted twelwe days (towards the end and immediately after the sensitive period). Four of the groups comprised young which had been isolated from each other until the first stimulation period; in the other four groups the young had been kept together in the experimental tanks. The age of the young when first stimulated was varied experimentally. Changes in approach and withdrawal behavior over time were studied along with e.g. changes in group strength. Age at first stimulation was found to be of some consequence but no clear differences were obtained between groups with different environmental experiences.     

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.     

Stimulus selection and the number of stimulus components

The number of word components in the compound stimuli of paired-associate lists were varied, and the words within a compound were presented either in a constant or in a variable order from trial to trial. The number of components, above one, had no appreciable effect on the difficulty of learning, and the variable order lists were more difficult than the constant order. Recall with the word components as cues showed that the amount of selection decreased with the variable order lists as the number of components increased. With the constant order lists, selection tended to remain constant as number of components increased. This was interpreted as the result of the availability of a rule for selection in the constant order conditions.     

Spiritual healing in the light of history

Pastoral Psychology - To summarize: we must accept the importance of spontaneous healings for religion. We can distinguish “charismatic” from “sacramental” cures. We should...     

Personality correlates of creativity among a sample of Jamaican adolescents

This exploratory research was designed to investigate personality correlates of creativity among a sample of 275 Jamaican adolescents, selected randomly from the fifth forms of eight high schools. A battery of 19 measures—8 tapping creativity and 11 tapping personality—was administered to this sample. Correlational analysis showed a number of significant relationships between the creativity and personality variables for the entire sample and few differences in the pattern of relationships when comparisons were made between the sexes. The outcomes of the investigation were in many ways supportive of international trends in creativity research.     

I—Alan W. Richardson

ABSTRACT This essay explores the uses that Michael Friedman and Bas van Fraassen have recently made of the work of Hans Reichenbach. It uses Friedman's work to complicate van Fraassen's invocation of Reichenbach's voluntarism in support of empiricism. It uses van Fraassen's work to motivate a concern with Friedman's neo-Kantian reading of Reichenbach. We are, finally, left with questions about the status and content of the account of the epistemic subject available to an epistemological voluntarist.
