Gender Differences in Perceptions of Household Crowding: Stress,Affiliation, and Role Obligations in Rural India1

Male and female researchers separately interviewed the male and female heads of household in each of 159 homes in three villages in northern India. Analyses revealed consistent gender differences, such that women, compared to men, rated their homes more negatively, experienced more physical symptoms, and thought the supply of resources was insufficient. Surprisingly, women also believed that their homes could house more people and were significantly more likely to want more children. In other words, women reacted negatively to crowding but also appeared to like having many people in the household. Possible reasons for this apparent contradiction are discussed.

Extraversion and electrodermal activity: arousability and the inverted-U

The Eysenck hypothesis that extraverts are less aroused or more inhibited than introverts has been subjected to a number of tests in the psychophysiological literature. Research to date suggests the need to clearly differentiate between tests of overall group differences in arousal or inhibition and studies of the differential reactions of the two groups to arousal manipulations. Psychophysiological studies of overall arousal differences in our laboratories and elsewhere have yielded somewhat inconsistent results for SCL, nonspecific response frequency, trials-to-criterion habituation and initial response amplitude, though dishabituation results are consistent with the expectation of higher amplitudes in introverts. Far more consistent are findings testing the inverted-U hypothesis, which suggests that introverts reach a point of optimal arousal at lower levels of stimulus input than do extraverts and hence should show earlier asymptotes and decrements in arousal measures. Using stimulus intensity and caffeine to manipulate arousal, we have found supportive results for SCL and several phasic measures, including the initial, test, and dishabituation responses. Overall, findings suggest that the two personality groups differ more clearly in arousability than in overall arousal level and that this difference is most consistent when conditions induce a rapid breakdown of inhibition and increase in arousal. Further research is needed to better understand the conditional relationship of extraversion to arousability, and arousal-manipulation paradigms would appear to be a fruitful initial approach to carrying out the needed research.     

PUNISHMENT OF SELF-INJURIOUS BEHAVIOR USING AROMATIC AMMONIA AS THE AVERSIVE STIMULUS

Punishment with aromatic ammonia was used to eliminate self-injurious behavior of an autistic woman during experimental sessions. The effects were reversible but were limited to experimental sessions until staff used the ammonia on the ward at all times.     

Effects of two levels of stimulus complexity upon hypothesis sampling systems among second and sixth grade children

Groups of second and sixth grade children each solved a series of discrimination-learning problems involving four and eight dimensions that contained blanktrial probes for the S′s hypothesis (H). There were significant effects of grade level on three dependent measures (learning, generating consistent H patterns, sampling locally consistent Hs). Main effects of stimulus complexity were significant on five measures (the three above, rejecting disconfirmed Hs, maintaining confirmed Hs). There were no interactions involving any of these measures. The hypothesis sampling system (Sy) observed in each problem was also determined. Among sixth grade Ss this measure was unaffected by stimulus complexity level. Second grade Ss generated logically structured Sys in 65% of four-dimensional, but only 30% of eight-dimensional problems. They generated stereotyped behaviors or unsystematic sequences of Hs in 70% of eight-dimensional, but only about 35% of four-dimensional problems. Detailed analyses revealed that among second grade Ss good information processors (in terms of four component processes above) usually imposed a logical structure on four-dimensional, but generated unsystematic sequences of Hs in many of eight-dimensional problems. Poor processors generated stereotyped behaviors in both four- and eight-dimensional problems.     

The treatment of homosexuality by ‘assisted’ covert sensitization

Covert sensitization is a procedure which pairs imagined scenes of an unwanted behavior, such as homosexuality, with scenes aversive to the patient, in an effort to diminish the strength of a given response. It has been employed in the treatment of a host of maladaptive approach behavior (Cautela, 1967). However, only anecdotal or single-case reports (Barlow et al., 1969; Cautela, 1966, 1967; Gold and Neufeld, 1965) have appeared regarding the treatment of homosexuality, and these have been unanimously positive. It was disappointing, therefore, in applying this technique to homosexuals, to find it ineffective. One patient complained that the stimuli ‘were not strong enough’. Another could not adequately visualize noxious scenes. This report describes our development of a bolstered from of covert sensitization, demonstrates its application to the treatment of homosexuals and provides follow-up data to evaluate the adequacy of such treatment.     

Speed-accuracy tradeoff in double stimulation: II. Effects on the second response

In the double-stimulation paradigm subjects respond to two successive stimuli. Previous research (Knight & Kantowitz, 1974) showed that a subject's speed-accuracy tradeoff (SAT) strategy interacted with the interval between the two stimuli to determine response performance to the first stimulus. The present experiment examined the influence of SAT strategy on response performance to the second stimulus. Interest focused on effects of SAT strategy upon the psychological refractory period (PRP) effect. If a single mechanism underlies beth first-and second-response performance (e.g., the PRP effect) in double stimulation, effects of SAT upon the second response should be similar to effects upon the first response. Results showed that the PRP effect appeared only when second-response accuracy was stressed. Under speed emphasis double-stimulation second-response latency never exceeded a single-stimulation baseline. This was analogous to first-response latency effects found by Knight and Kantowitz (1974). Response grouping was strongly influenced by SAT strategy and two response-grouping mechanisms were distinguished. Implications of these and interresponse time data for models of double-stimulation performance are discussed.     

CLASSICAL CONDITIONING OF DECREASES IN HUMAN SYSTOLIC BLOOD PRESSURE1

Decrease in human systolic blood pressure of 4.35 mm Hg (range: 0 to 12 mm Hg) were classically conditioned in normal and hypertensive subjects using a delayed conditioning paradigm in which a 30-sec auditory stimulus (the conditioned stimulus) was followed immediately by tilting the subject 15° head-down to elicit small decreases in blood pressure. Conditioning occurred within five trials. A control group demonstrated that sensitization of the reflex by repeated tilting could not account for the blood-pressure decreases associated with the conditioned stimulus in experimental subjects.
