Successful women and women's colleges: Is there an intervening variable in the reported relationship?

This study examined the relationship between career success and the baccalaureate degree origin of women. Analyses of data collected on the educational backgrounds of 126 successful women confirmed previous findings that graduates of women's colleges were more likely to attain career success than graduates of coeducational institutions. Results also identify graduate education as a possible intervening variable in the relationship.The authors wish to thank Dr. Elizabeth Tidball for providing us invaluable data she accumulated for previous studies.     

Novelty assessment in the brain and long-term memory encoding

Recent positron emission tomography (PET) studies have identified neuronal components of widespread novelty-assessment networks in the brain. We propose that the efficacy of encoding on-line information into long-term memory depends on the novelty of the information as determined by these networks, and report a test of this “novelty/encoding” hypothesis. Subjects studied a list of words. Half of the words were “familiar” by virtue of their repeated presentation to the subjects before the study of the critical list; the other half were novel, in that they had not previously been encountered in the experiment. The results conformed to the prediction of the novelty/encoding hypothesis: accuracy of explicit (episodic) recognition was higher for novel than for familiar words.     

BEHAVIORAL ASSESSMENT AND TREATMENT OF CHRONIC FOOD REFUSAL IN HANDICAPPED CHILDREN

In this study, we examined the eating behavior of four handicapped children, none of whom exhibited self-feeding skills. All children had a history of food refusal and were nutritionally at risk; one child received all nourishment by way of a gastrostomy tube. Baseline data taken during mealtimes indicated that all children accepted very little food, expelled food frequently, and engaged in a number of disruptive behaviors. Treatments consisted of one or more of the following contingent events: social praise, access to preferred foods, brief periods of toy play, and forced feeding. Results of multiple-baseline and reversal designs showed marked behavioral improvement for each child and increases in the amount of food consumed. Further improvements were noted at follow-up, which ranged from 7 to 30 months posttreatment.     

Perceived punishment and reward values of supervisor actions

The study investigated employee perceptions about the reward or punishment values inherent in a variety of supervisor actions. Actions viewed as most rewarding were generally actions that possessed (a) public visibility, (b) tangibility, (c) implied esteem, and (d) long-term implications. Actions viewed as punishing or aversive involved similar characteristics. Visibility appeared to be most strongly related to perceived severity. In contrast with suggestions in the literature (cf. León, 1981), substantial levels of agreement among raters were found for aversive as well as rewarding actions. Also reviewed are characteristics of leader actions that received mixed ratings from respondents.     

When item recognition and visual search functions are similar

The effect of prolonged practice upon item recognition performance was investigated under conditions of nested positive sets and complete response consistency. Nesting is defined by each positive set containing all the items contained in smaller positive sets. Response consistency is defined by each item in the stimulus set consistently requiring only a positive or only a negative response. A low error level was maintained. Twelve Ss worked with three positive set sizes in each of 36 sessions. Half the Ss worked with digit stimuli and half with pictures. The item recognition function (that function relating response latency and positive set size) was found to be negatively accelerated throughout the course of practice. The effect of positive set size decreased significantly (p < .001) with practice, and set size effects were significantly (p < .03) greater for positive response trials than for negative response trials. Kind of item had no effect on the set size effect. A theoretical framework consistent with these results is suggested. Results from the present study are compared with findings obtained previously from visual search studies. It is concluded that when the procedures in both tasks include response consistency, nested positive sets, and low error levels, the effects of prolonged practice upon the set size from item recognition and visual search are qualitatively very similar.     

The effect of repetition on iconic memory

The present experiment examined the influence of repetition on iconic memory using the Sperling (1960) procedure. It was assumed that the whole-report procedure would estimate only information available from a somewhat more permanent memory system than the icon, while the partial report would estimate both that information and the information available in the icon. The difference between the whole and partial report was assumed to measure information available only in the icon. Across a series of 160 displays one particular display occurred half the time (80 repetitions). The results indicated that the repetition influenced recall from the more permanent memory system assessed by whole report, but had no influence on the information available from the icon (partial report minus whole report).     

TEMPORAL INTEGRATION OF PERCEPTUAL RESPONSE TO SUPRALIMINAL ELECTRICAL STIMULATION

E kman , G., F röberg , J. & F rankenhaeuser , M. Temporal integration of perceptual response to supraliminal electrical stimulation. Scand. J. Psychol ., 1968, 9, 83–88.—The effect of duration of electrical stimulation on perceived unpleasantness was investigated in 10 subjects. Duration of stimulation ranged from 0.05 to 3.00 sec. Three levels of intensity were investigated representing 2, 3, and 4 times the individual sensation threshold. For all stimulus intensities perceived unpleasantness was a simple logarithmic function of stimulus duration over the whole temporal range. This relation describes the trend of both the group data and the data from most individual subjects. The results support previous findings over a narrower temporal range and agree with results recently obtained in several additional sense modalities.     

The High School Dropout Goes to College

662 former secondary school leavers of academic potential were identified for a program designed to give selected dropouts a chance to enter the University of Toledo. Following responses to questionnaires, 94 students were selected for further screening, which resulted in the final selection of 50 candidates. 34 members of the experimental group attended pre-school workshops in reading, writing, and study habit skills. 31 enrolled as regularly admitted students in academic programs of the university for the academic year. 11 completed their freshman year, although only 4 were making satisfactory academic progress.     

Effects of prolonged gravitational stress on performance

Effects of prolonged radial acceleration on performance were studied in eight series of experiments: (I) Visual choice reaction time, (II) Visual acuity, (III) Accuracy of movement, (IV) Perceptual speed, (V) The Stroop test, (VI) The 100 - 3 test, (VII) Multiplication and (VIII) Time perception.
