Classical conditioning and extinction of human systolic blood pressure

Fifty-five male and female undergraduates underwent 3 sessions of conditioning and one of extinction. Shock (UCS) occurred intermittently during light-on (CS+) and never in light-off (CS-). Results showed that (1) pressure in CS+ was significantly higher than CS-throughout all sessions; (2) within session adaptation was significantly retarded while incoming pressure levels did not adapt across sessions; (3) conditioned effects persisted 6 months after the last shock session; (4) verbal information as to non-appearance of shock significantly dropped pressure levels and reduced the discriminative light effect; (5) the post-shock unconditioned pressure response was a peak rise at 52 seconds, then a decrease which stabilized to the pre-shock level at 2 minutes. Pavlovian control of blood pressure was demonstrated and the present methodology offers an explicit procedure for further laboratory exploration.     

Group therapy for Catholic nuns

Summary The results of one year's experience of group therapy for an entire convent (Mother Superior and eight nuns) of Catholic nuns indicate that the benefits derived were extremely important. In the early phase, significant problems had to be met and worked through. It was my impression that in one year's time all of the nuns had grown, were more aware of themselves, were more confident and more accepting of themselves and others.He has been chief clinical psychologist at the Eastern Oregon State Hospital and consulting psychologist at the Oregon State Board of Health.     

Cross-domain semantic priming in normal subjects and a prosopagnosic patient

Cross-domain semantic priming of person recognition (from face primes to name targets at 500msecs SOA) is investigated in normal subjects and a brain-injured patient (PH) with a very severe impairment of overt face recognition ability. Experiment 1 demonstrates equivalent semantic priming effects for normal subjects from face primes to name targets (cross-domain priming) and from name primes to name targets (within-domain priming). Experiment 2 demonstrates cross-domain semantic priming effects from face primes that PH cannot recognize overtly. Experiment 3 shows that cross-domain semantic priming effects can be found for normal subjects when target names are repeated across all conditions. This (repeated targets) method is then used in Experiment 4 to establish that PH shows equivalent semantic priming to normal subjects from face primes which he is very poor at identifying overtly and from name primes which he can identify overtly. These findings demonstrate that automatic aspects of face recognition can remain intact even when all sense of overt recognition has been lost.     

Ratings of emotion in faces are influenced by the visual field to which stimuli are presented

This experiment was designed to assess the differential impact of initially presenting affective information to the left versus right hemisphere on both the perception of and response to the input. Nineteen right-handed subjects were presented with faces expressing happiness and sadness. Each face was presented twice to each visual field for an 8-sec duration. The electro-oculogram (EOG) was monitored and fed back to subjects to train them to keep their eyes focused on the central fixation point as well as to eliminate trials confounded by eye movement artifact. Following each slide presentation, subjects rated the intensity of the emotional expression depicted in the face and their emotional reaction to the face on a series of 7-point rating scales. Subjects reported perceiving more happiness in response to stimuli initially presented to the left hemisphere (right visual field) compared to presentations of the identical faces to the right hemisphere (left visual field). This effect was predominantly a function of ratings on sad faces. A similar, albeit less robust, effect was found on self-ratings of happiness (the degree to which the face elicited the emotion in the viewer). These data challenge the view that the right hemisphere is uniquely involved in all emotional behavior. The implications of these findings for theories concerning the lateralization of emotional behavior are discussed.     

SEX ROLES AND PERCEPTIONS OF FEMININITY AND MASCULINITY OF HISPANIC WOMEN

This article evaluates the research conducted on sex roles and perceptions of femininity and masculinity of Hispanic women. It begins with a critical review of early social and anthropological studies in which the roles of Hispanic women before the advent of the women's movement in the 1960s are described. The paper continues with more recent psychosocial studies that question the traditional portrayal of male–female roles and allocation of power in Hispanic families. Finally, the studies on Hispanics that measure the psychological dimension of femininity and masculinity are reviewed and summarized in a table including authors, sample, methodology and results.     

The role of causal connections in the retrieval of text

In two experiments, subjects read a series of passages, each containing two target concepts that appeared in widely separated positions within the passage. Following each passage, the time to retrieve each of these concepts was recorded. Several measures from both the Kintsch and van Dijk (1978) model and Trabasso and Sperry’s (1985) causal analysis were derived to predict retrieval time. Regression analyses showed that substantial proportions of variance were accounted for by measures derived from a causal analysis. Neither physical position nor measures based on the Kintsch and van Dijk model accounted for significant proportions of variance. Following Experiment 2, a reanalysis of O’Brien’s (1987) results revealed that the number of causal connections to an antecedent was a significant predictor of antecedent search time. Results are discussed in terms of a spread of activation through an integrated text representation in which causal connections play a major role.
