AIDS prevention for intravenous drug users in the community: Street-based education and risk behavior

Conducted a study of behavior change associated with a street-based AIDS education project targeted to intravenous (IV) drug users in San Francisco. Two cross-sections were sampled from drug detoxification clinics and street locations in 1986 (n = 438) and 1987 (n = 623). Significant increases were reported in the percentage of IV drug users who used bleach to decontaminate syringes, who did not share needles in past year, and in condom use. A significant reduction in an index of the number of needle-sharing partners was reported. Respondents ranked treatment program as most important source of AIDS information prior to implementation of the program, and ranked outreach workers as most important after implementation. Findings suggest that this community-based outreach program had at least some impact on knowledge about AIDS and may have led to reductions in behaviors known to transmit HIV.     

An MMPI-based empirical model of malingering and deception

The empirically-based model of malingering and deception described by Rogers (1984b) was operationalized using MMPI and clinical interview data. Subjects (N = 159) were patients committed to an inpatient forensic hospital as ‘Incompetent to Stand Trial’ or ‘Not Guilty by Reason of Insanity’. Inter-rater reliability was acceptable for the 11 criteria used to define response styles. Each subject was categorized into one of five response style groups: ‘Reliable’, ‘Malingering’, ‘Defensive’, ‘Irrelevant’, or ‘Unclassifiable’. Factor analysis of the rating criteria yielded four factors, three of which are comparable to the assigned groups, providing some validation for the constructs underlying these groups.     

The stroop effect and the myth of automaticity

A widespread view in cognition is that once acquired through extensive practice, mental skills such as reading are automatic. Lexical and semantic analyses of single words are said to be uncontrollable in the sense that they cannot be prevented. Over the past 60 years, apparently convincing support for this assumption has come from hundreds of experiments in which skilled readers have processed an irrelevant word in the Stroop task despite explicit instructions not to, even when so doing would hurt color identification performance. This basic effect was replicated in two experiments, which also showed that a considerable amount of semantic processing is locally controlled by elements of the task. For example, simply coloring a single letter instead of the whole word eliminated the Stroop effect. This outcome flies in the face of any automaticity account in which specified processes cannot be prevented from being set in motion, but it is consistent with the venerable idea that mental set is a powerful determinant of performance.     

Do worksite stress management programs attract the employees who need them and are they effective?

Employees who planned to attend a worksite stress management program (volunteers), those who planned not to attend (nonvolunteers), and those who had participated in worksite stress management training were assessed on the variables of work stressors, perceived stress, and organizational spontaneity (extrarole) behavior. Twelve hundred hospital employees were randomly selected from seven VA hospitals that had been offering a stress management program for at least 5 years. Participants received questionnaire packets in the mail and 461 (38%) of the employees responded. The results showed that volunteers reported significantly more perceived stress than the nonvolunteers. However, volunteers did not report greater frequency or intensity of work stressors. Also, respondents who had participated in past stress training reported less perceived stress than volunteers and significantly more organizational spontaneity behavior than respondents who had not participated in past stress training. These findings suggest that employees who plan to attend stress training have the greatest need and that the stress intervention reduces perceived stress levels and, possibly, affects work behavior.     

The McGurk effect in infants

In the McGurk effect, perceptual identification of auditory speech syllables is influenced by simultaneous presentation of discrepant visible speech syllables. This effect has been found in subjects of different ages and with various native language backgrounds. But no McGurk tests have been conducted with prelinguistic infants. In the present series of experiments, 5-month-old English-exposed infants were tested for the McGurk effect. Infants were first gaze-habituated to an audiovisual /va/. Two different dishabituation stimuli were then presented: audio /ba/-visual /va/ (perceived by adults as /va/), and audio /da/-visual /va/ (perceived by adults as /da/). The infants showed generalization from the audiovisual /va/ to the audio /ba/-visual /va/ stimulus but not to the audio /da/-visual /va/ stimulus. Follow-up experiments revealed that these generalization differences were not due to a general preference for the audio /da/-visual /va/ stimulus or to the auditory similarity of /ba/ to /va/ relative to /da/. These results suggest that the infants were visually influenced in the same way as Englishspeaking adults are visually influenced.     

Influences of Destructive Personality Information on Decision Making1

This study examined the effects of information about a landlord's personality on juror judgments for a landlord-tenant civil trial. The personality information manipulated was specifically relevant to destructive acts. Alternative versions of witness testimony were used to describe a landlord either high or low on need for power. treating people as objects, and negative life themes. This information strongly influenced aspects of the schema for this case constructed by the individual mock jurors. Destructive personality information caused dislike of the landlord and lowered the credibility of his story. If the landlord treated people as objects, the credibility of the tenant's story and positive evaluations of the tenant increased. Juror judgments about relative fault were strongly shifted by destructive personality information. An empirical model for juror decisions indicated a dynamic interplay of story components and fault judgments.     

Racial Attitudes and the Death Penalty1

This study investigated the relationship between overt and subtle forms of racism with Whites' recommendations for capital sentencing of Black and White offenders convicted of murder. White participants (n= 104) viewed 5 other “jurors” (all Whites or 4 Whites and 1 Black) on videotape individually presenting their decisions to vote for the death penalty in the case. It was hypothesized that the bias of high prejudice-scoring participants would be overt, but that the pattern for low prejudice-scoring participants would be more complex. As predicted, among high prejudice-scoring participants, Black defendants received stronger recommendations for the death penalty than did White defendants. Among low prejudice-scoring White participants, Black offenders received stronger recommendations for the death penalty only when a Black juror advocated the death penalty.     

Cerebral Anesthetization for Localization of Speech: The Contribution of W. James Gardner

In 1949, the neurologist Juhn Wada reported the first use of a new procedure for determining the localization of speech and language in neurological patients: examination of the effects on speech and language after injecting a barbiturate, sodium amytal, into the internal carotid artery of each hemisphere in succession. By the 1960s, Wada'sIntracarotid Amobarbital Procedure,orIAP,had become the method of choice for identifying the speech-dominant side in one kind of neurological patient, persons with epilepsy who are candidates for surgical resection, and it remains so today. In 1941, however, an American neurosurgeon, W. James Gardner, reported his use of a different anesthetization procedure for speech localization in neurological patients. Instead of injecting sodium amytal through the blood supply, as in the IAP, Gardner injected procaine hydrochloride directly into cortical tissue. In this paper, we provide a brief biography of Gardner. We then discuss his method of cortical anesthetization, the theoretical and empirical background guiding his use of this method and his choice of patients, and, finally, the fate of Gardner's method within the scientific community.     

The Unintended Negative Consequences of Sympathy for the Stigmatized1

Research on attitudes toward the stigmatized indicates that negative feelings and stereotypes toward the stigmatized are often mixed with positive feelings of sympathy and concern. Three studies investigate the hypothesis that positive outcomes for the stigmatized that are motivated by sympathy may have unintended negative consequences for self-esteem, affect, and motivation. Subjects were asked to imagine themselves in the position of a stigmatized person who received a job either because he or she was qualified, or out of sympathy for a stigmatizing condition. Results indicated that subjects reported lower state self-esteem, more negative affect, and lowered work motivation when the job was offered out of sympathy rather than on the basis of qualifications. Study 2 showed that the negative effects of sympathy occur whether the basis for the sympathy is prejudice and discrimination or mobility problems faced by the stigmatized individual. The third experiment showed that sympathy has negative effects when the sympathy is based either on individual or group-based problems imposed by the stigmatizing condition. The findings are discussed in terms of the attributional ambiguity surrounding positive outcomes faced by the stigmatized and applied to the effects of affirmative-action programs.
