Men's and women's ratings of life satisfaction by age of respondent and age interval judged

A total of 432 people in six age groups rated the satisfaction of their current, past, and projected future lives. Average ratings for men and women did not differ. However, the triple interaction of sex × age of respondent × age interval judged indicated an optimism toward the future on the part of women. Compared with men of the same age, women judged the age interval prior to their own, as well as their present age interval, as being less satisfying than did the men. But women expected levels of satisfaction in the future to be higher than men expected. This optimism is attributed to socialization differences as well as the hope engendered by the current feminist movement.     

Interfacing the PET/CBM with Coulbourn’s DynaPort for experimental control and data acquisition

Component changes to Coulbourn’s DynaPort that are necessary to ensure reliable data exchange with laboratory computers are discussed. Also provided and explained is a data communications package of BASIC and assembly language routines that will permit the PET/CBM to retrieve data from the DynaPort.     

Gender identity,interactionism, and politics: A reply to Rogers and Walsh

This article is a reply to a recent article by Rogers and Walsh (Sex Roles, 1982, 8, 269–281). We disagree with some of their interpretations and criticisms of the psychomedical research on the development of sex differences. Thus, there is a discussion of the reasoning and strategies of the biological approach in this research area. However, we also support and extend some of their suggestions relevant to gender and sex.     

Personality correlates of occupational status according to Holland types

The present investigation sought to identify personality correlates of occupational status. Because occupational status is a direct function of occupation, the relationship between personality and status was examined both within and across occupational groups using Holland's 1973 typology. Four two-way analyses of covariance of 16PF (Sixteen Personality Factor Questionnaire, Form A) second-order personality factors were performed using data from 175 employed adult males. No single personality factor was associated with status across occupational types. Among Social occupations, the low-status group had higher Extraversion and lower Anxiety scores than the high-status group. In general, the relationship between personality factors and occupational types provided additional confirmation of Holland's theory using an employed adult sample.     

Probabilistic multidimensional scaling: Complete and incomplete data

Simple procedures are described for obtaining maximum likelihood estimates of the location and uncertainty parameters of the Hefner model. This model is a probabilistic, multidimensional scaling model, which assigns a multivariate normal distribution to each stimulus point. It is shown that for such a model, standard nonmetric and metric algorithms are not appropriate. A procedure is also described for constructing incomplete data sets, by taking into consideration the degree of familiarity the subject has for each stimulus. Maximum likelihood estimates are developed both for complete and incomplete data sets. This research was supported by National Science Grant No. SOC76-20517. The first author would especially like to express his gratitude to the Netherlands Institute for Advanced Study for its very substantial help with this research.     

SOME EFFECTS OF REINFORCEMENT SCHEDULES IN TEACHING PICTURE NAMES TO RETARDED CHILDREN1

The effects of several different schedules of primary reinforcement were compared in a picture-naming task with retarded children. In Experiment I, number of correct responses and learning rate were higher under fixed-ratio schedules than under continuous reinforcement. In Experiment II, number of correct responses and learning rate tended to be greater under intermediate than under low or high fixed-ratio schedules. In Experiment III, number of correct responses was higher under interlocking schedules, in which the response requirement increased with time following the previous reinforcement, than under comparable fixed-ratio schedules. Learning rates were generally low and, perhaps because of this, not very different under the two types of schedules in this experiment. Accuracy (i.e., proportion of trials on which correct responses occurred) was typically high and insensitive to variations in schedule and schedule parameter throughout each experiment.     

Persistence of response prevention effects following retraining of escape behavior

This study evaluated the effects of response prevention procedures on the extinction of escape behavior following the reinstatement of shock-escape training prior to the start of extinction. Female hooded rats were assigned to four groups (N = 10) in a factorial design which orthogonally combined response prevention or pseudo-prevention procedures with escape retraining or no retraining procedures. Results showed that prevention reliably impaired shock-escape behavior on early retraining trials; but this effect dissipated completely by the end of retraining. In extinction, prevention reliably facilitated the extinction of escape behavior relative to that of pseudo-prevention controls; but the degree of facilitation was reliably attenuated by retraining procedures. These findings were related to the competing response interpretation of prevention effects.     

Sensory features and the reduction of imaginal interference

Interference generated among the sensory features of PA stimulus words is not eliminated by processing at the imaginal level. This experiment was planned to test the reverse possibility. Will interference generated by similar imaginal referents be eliminated by sensory overlap between the stimuli and their responses? Thus, stimulus words did or did not evoke similar images, pairs did or did not share initial letters, and lists were acquired either under an instructional set t o form interacting images or to repeat the items aloud. The results indicated that the imagery strategy was superior to the repetition strategy in all conditions, and that stimulus interference was statistically eliminated when pairs shared the same initial letters. The findings were interpreted as consistent with a levels of processing conceptualization.     

Spatial localization of warmth

This study explored the ability to localize warmth sensations produced by radiant stimulation of the forearm. The subject’s task was to state on which side of a tactile reference line warmth was perceived. Percentage correct improved with increasing intensity of the radiation, as well as with increasing distance from the reference line. There appears to be an inverse relation between the ability to make spatial judgments and the degree of spatial summation. At low levels of stimulation, intensity and area both contribute heavily to the magnitude of a warmth sensation and spatial localization is poor; but with increasing level, area contributes less and less to sensation and localization is better.
