Implications of measurement of eye fixations for a psychophysics of form perception

It was suggested that insights into feature analysis of processes involved in form identification might be gained from an analysis of eye movements made by Ss as they identified patterns. Fixations were measured during identifications of histoforms, polygons, and Vargus 10 figures. Eye fixations were measured, and Ss rated sections of the figures in terms of their importance. Eye fixations were measured in terms of number of changes and duration of fixations. The number of changes in fixation were found to reflect only individual differences. Duration of fixation was found to vary significantly with location within figures, with fixations being longest where changes of contour occurred. There was also a tendency to look longer at the top of polygons and Vargus 10 figures and at the center of histoforms. Ratings of importance were highest for sections of figures fixated for longer duration-generally areas in which changes of contour were present.     

The preventive and therapeutic effects of two school mental health programs

In 30 classrooms randomly assigned to experimental conditions, effects on mothers' reports of behavior symptoms were compared for (a) a parent education program; (b) an in-school program of consultation, counseling, training, and referral; and (c) control classrooms. A sample of 426 families were followed for 30 months from the child's entry into third grade. A simple unweighted count of the number of symptoms reported in a home interview had adequate validity, good reliability, low reactivity, and intrinsic significance. Both programs had significant preventive and therapeutic effects on boys but not on girls. Effects were immediate in the upper middle class families, delayed in the lower class families.The larger study on which this article is based was initiated some years ago by Professor Glidewell and his colleagues, and represents a pioneering research effort in the field of community psychology. The present article was prepared by the authors in response to an invitation from the Editor to report important and still timely aspects of the original study that were not previously published in archival sources. We are grateful to Professor Glidewell and his colleagues for giving us this opportunity to make their findings more generally available to community psychology researchers.This work was supported by research grant M-592 from the National Institute of Mental Health, U.S. Public Health Service, and the St. Louis County Health Department.     

Word frequency and age of acquisition as determiners of picture-naming latency

In multiple-regression analysis of picture-naming latencies from an experiment modelled on Oldfield and Wingfield's (1965), with 94 stimuli and 37 adult subjects, two word frequency measures had insignificant beta weights, while two measures estimating age at which the word was learned had highly significant weights. Objects whose names were learned early were named faster. This result may have important implications for the interpretation of studies using word frequency as a critical variable. It is suggested that word retrieval may be a one-stage process that depends upon the age at which a word was learned.     

TEACHING COIN SUMMATION TO THE MENTALLY RETARDED1

A procedure to teach four mild and moderately retarded persons to sum the value of coin combinations was tested. Subjects were first taught to count a single target coin, and then to sum that coin in combination with coins previously trained. Five American coins and various combinations were trained. Modelling, modelling with subject participation, and independent counting by the subject constituted the training sequence. The subjects improved from a mean pretest score of 29% to 92% correct at posttest. A four-week followup score showed a mean of 79% correct. A multiple-baseline design suggested that improvement in coin-counting performance occurred only after the coin was trained. The results indicate that this procedure has potential for teaching the retarded to sum combinations of coins in 5 to 6 hr of instruction.     

Motivation concepts and sexual identity

The association dimension of the Picture Identification Test (PIT) was used to investigate the motivation concepts of male and female university students classified as Declared Homosexual, Sexually Uncertain, Clinical Control, and Normal Control. The t test was used to identify Need Association Dyads which discriminated (p < .01) groups. Greater than chance numbers of variables discriminated each of the pairs of groups within each sex except the Sexually Uncertain versus Clinical Control Male groups, the Declared Homosexual versus Clinical Control Female groups, and the Declared Homosexual versus Normal Control Female groups. PIT Need Association Dyads were discussed as a type of implicit personality theory assessment with emphasis on the beliefs subjects hold about the simultaneous expression of needs.

A HULLIAN CONSTANT AS AN INDEX OF INTELLIGENCE: TWO EMPIRICAL INVESTIGATIONS

Following Clark Hull, it is widely considered that the asymptote of the learning curve represents motivational factors, but that rate of approach to asymptote ('i') represents associational factors. The suggestion that i may be a measure of intelligence was tested empirically in two studies. An initial exploratory study yielded a positive correlation between i and IQ. A more rigorous replication did not. The results are discussed briefly.     

Psychoanalytically oriented short-term groups for outpatients: Unsettled issues

The psychoanalytic approach to short-term group therapy for outpatients has been less prevalent than other approaches. Unsettled issues associated with this approach concern the feasibility of carrying out psychoanalytic work on an ongoing basis, patient selection, group composition, patient preparation, therapist technique, and cotherapy. Recent literature relevant to a conceptual consideration of these issues is reviewed. A vignette from a recent therapy group is presented as part of a clinical consideration of the issues. In addition, practical suggestions for conducting such groups are provided.This article was derived from a paper presented at the Seventh Annual Meeting of the Canadian Group Psychotherapy Association, October 16, 1986, Mont Tremblant, Canada.     

“Higher” and “lower”: Comparative and categorical interpretations by children

Three-, four-, and five-year-old children's categorical and comparative understanding of high and low were examined in two experiments. Categorical knowledge was assessed by presenting subjects with a single object at varying heights (from 0 to five feet above the ground), and asking if the object was high or low. Comparative understanding of the terms was assessed by showing children two objects at a time and asking which was higher or lower. We observed two patterns of performance in children's categorical treatments: younger children in particular defined disjoint categories for high and low such that they only labelled the extreme heights as high or low, and maintained that middle heights were neither high nor low. Older children defined either-or categories such that all heights were labelled either high or low. We also found that children who defined either-or categories made correct comparative judgments across the entire range of variation whereas children who defined disjoint categories could only judge which of two objects was higher if the objects were not low (at 0 and 1 feet) and which of the objects was lower if the objects were not high (at 4 and 5 feet). The results were interpreted as reflecting a lack of appreciation that the terms are interdefined as negations of each other, and were discussed in terms of the similar semantic-congruity effects found in adults.
