The Role of Affect and Worldviews as Orienting Dispositions in the Perception and Acceptance of Nuclear Power1

Recent research in risk perception has examined the role of affect and worldviews as orienting dispositions that guide people's decisions about complex and risky topics such as nuclear energy. This study tests and supports the hypothesis that worldviews and affect-laden imagery are highly predictive of perceptions of risk from nuclear power and support for that technology. Furthermore, affect and worldviews each contribute independently to the prediction of nuclear support. We find also that a person's affective imagery associated with nuclear power is systematically related to their worldviews. We conclude that affect and worldviews appear to play similar roles as orienting mechanisms, helping people navigate in a complex, uncertain, and sometimes dangerous world. The implication of this view for the practice of risk communication is briefly discussed.     

Conditioned Inhibition Produced by Extinction of a Conditioned Stimulus

Four experiments used a conditioned taste aversion procedure to examine the potential for CS-alone extinction treatment to produce a conditioned stimulus that possesses inhibitory properties. In Experiment 1, saccharin was paired with LiCl, and then saccharin was presented alone for several trials to produce extensive behavioral extinction. Animals receiving this treatment were retarded in reacquiring conditioned responding to saccharin relative to control subjects receiving conditioning to the flavor for the first time. In Experiment 2, the extinguished saccharin stimulus was shown to decrease conditioned responding to a known excitor when the two stimuli were presented in compound as a summation test. Experiments 3A and 3B replicated the findings of Experiments 1 and 2 while providing evidence that the effects were not due to the differential effects of neophobia during testing. These three experiments revealed that an extinguished conditioned excitor passes retardation and summation tests for conditioned inhibition. Experiment 4 found that extinction of a known excitor was slowed when the excitor was extinguished in compound with a previously extinguished conditioned stimulus. That is, an extinguished CS provided protection from extinction to another CS, a finding also consistent with the view that extinction produces conditioned inhibition.     

Prosodic influences on the resolution of temporary ambiguity during on-line sentence processing

We present three experiments designed to investigate the role of prosody during sentence processing. The first investigated the question of whether an utterance's prosodic contour influences its comprehension on-line. We spliced the beginning and end portions of direct object and embedded clause sentences and observed the consequent effects on comprehension using a dual-task procedure to measure processing load. Our second experiment sought to determine-whether the constituent structure of these sentences could be reliably predicted using prosodic information. We found that the duration and F₀ contour associated with the main-clause verb and the following NP reliably distinguished between the direct object and embedded clause constructions. In the final experiment, we manipulated the duration of the main-clause verb and found that subjects used this information to guide their initial parse during on-line sentence comprehension. The need for a model of sentence processing that addresses the use of prosodic information is discussed.The work reported in this paper was supported in part by NTH grant DC00494.     

Reinventing Ethnicity in Yucatan

The contributors to this issue examine variousinterconnections among gender, class, ethnicity, region,and nation through a focus upon Yucatecan women. Somecommon themes that link the papers relate to rural social and economic transformation,migration, and the redefinition of indigenous ethnicity.We are given glimpses of the emergence of new andpreviously unthinkable configurations of class andethnicity in Yucatan, a process that has taken placethroughout Latin America in recent decades. A number ofpapers describe situations of partial proletarianizationin which men migrate from rural areas to cities, while women remain in the countryside. Theauthors stress the often-overlooked contributions madeby indigenous women to household economy, and also tendto stress continuity, complementarity, and the mediating or brokerage position of women. Contradictionswithin the household and between rural and urban areasshould also be considered. The assertion that Mayawomen's role in social transformations is primarily that of guardians and defenders of tradition isproblematic. Tradition andmodernity are not fixed categories, norare they qualities of people or collectivities, but waysof talking about the relationship between the present andthe past, about social and spatial distance from centersof polity and economy. Staking a claim to being theguardians of tradition or of an ethnic essence may be a wayof defining a social position inthe present, in the context of contemporaryrelationships within the community. This collectionprovides compelling evidence of the reinvention ofethnicity in contemporary Yucatan, but our assumptionsabout ethnicity and tradition should be approached withthe same critical attitude these authors bring to thestudy of gender.     

FEMALE PARTNERS OF BISEXUAL MEN What They Don't Know Might Hurt Them

Individual interviews with 350 behaviorally bisexual men aged 18–30 revealed that 71% of their female sexual partners and 59% of their steady female sexual partners in the past 6 months had not been aware of their homosexual activity. Rates of nondisclosure were higher for African-American than White men. Compared to nondisclosers, men who disclosed to all their female partners were less self-homophobic and perceived their friends, families, and neighbors as more accepting of their homosexual behavior. Compared to men who had disclosed, the nondisclosers had more female partners and used condoms less consistently with women.     

Gaze avoidance: Personality and social judgments of people who avoid direct face-to-face contact

Some people maintain direct, face-to-face contact during interaction, whereas others avert their gaze or turn their face while interacting. Research on individual differences in gaze avoidance, while sparse, falls into two areas. One concerns the personality and psychopathology correlates of gaze aversion, and the other concerns social judgments made of people who avert their gaze during interaction. The findings generally show that gaze aversion is associated with unfavorable traits (shyness, social anxiety, risk for schizophrenia) and negative social evaluations (gaze averse people are rated as more deceptive and less sincere). The present study took advantage of an archival data set that contained facial photographs from which gaze avoidance could be scored. The correlates of gaze avoidance were different for men and women. Gaze avoidant men tended to be emotionally inhibited and overcontrolled, and reported a high incidence of various psychosomatic and physical symptoms. Gaze avoidant women, on the other hand, were high on measures of psychopathy, hysteria, and traditional femininity, they tended to have fewer physical symptoms. Gaze avoidant women were also viewed by others in a negative light (as being disagreeable, unconscientious, unattractive, and even somewhat lower on intelligence). In males, none of the social judgment variables correlated significantly with gaze avoidance. Results are discussed in terms of sex differences in the meaning and communicative function of this non-verbal social behavior.     

The psychologist's role in assessing and facilitating patients' knowledge of advance directives in medical settings: A preliminary investigation

In a time of budgetary shortfalls in the medical industry, an aging population, and an increased emphasis on health care choices, psychologists are being called upon to administer advance medical directive programs to patients. This study reports preliminary findings from a program to assess and facilitate patients' knowledge of advance directives (ADs) by the Psychology Service at the Ann Arbor VA Medical Center. The participant pool included 243 male veteran patients admitted to medical and surgical wards at the hospital. The intervention included the use of a computer-generated prompt for consultation, which was sent to the psychology staff in response to a patient inquiry regarding ADs. It also involved an increased emphasis on the delivery of written material on ADs by the admissions clerks. The intervention appeared to result in a modest increase in patients' knowledge of advance directives. Suggestions are offered for areas that should be emphasized in future attempts to increase patients' knowledge and utilization of advance directives.     

The visual perception of rigid motion from constant flow fields

Four experiments investigated observers’ judgments of rigidity for different types of optical motion. The depicted structural deformations were of two types: (1) those with nonparallel image trajectories that are detectable from the first-order spatiotemporal relations between pairs of views; and (2) those with parallel image trajectories that can only be detected from higher order relations among three or more views. Patterns were composed of smooth flow fields in Experiments 1 and 3, and of wire frame figures in Experiments 2 and 4. For both types of display, the nonrigidity detectable from the first-order spatiotemporal structure of the motion sequence was much more salient than the deformation detectable only from the higher order spatiotemporal structure. These results indicate that observers’ judgments of rigidity are based primarily on a two-view analysis, but that some useful information can be obtained under appropriate circumstances from higher order spatiotemporal relations among three or more views.
