Risk perceptions: assessment and relationship to influenza vaccination.

OBJECTIVE: Accurate measurement of beliefs about risk probability is essential to determine what role these beliefs have in health behavior. This study investigated the ability of several types of risk perception measures and of other constructs from health behavior theories to predict influenza vaccination. DESIGN: Prospective study in which students, faculty, and staff at 3 universities (N = 428) were interviewed in the fall, before influenza vaccine was available, and again early in the next calendar year. MAIN OUTCOME MEASURE: Self-reported influenza vaccination. RESULTS: Two interview questions that asked about feeling at risk and feeling vulnerable predicted subsequent behavior better (r = .44, p = .001) than 2 questions that asked for agreement or disagreement with statements about risk probability (r = .25, p = .001) or 4 questions that asked respondents to estimate the magnitude of the risk probability (r = .30, p = .001). Of the 4 perceived risk magnitude scales, a 7-point verbal scale was the best predictor of behavior. Anticipated regret was the strongest predictor of vaccination (r = .45, p = .001) of all constructs studied, including risk perceptions, worry, and perceived vaccine effectiveness. CONCLUSION: Risk perceptions predicted subsequent vaccination. However, perceived risk phrased in terms of feelings rather than as a purely cognitive probability judgment predicted better. Because neither feeling at risk nor anticipated regret is represented in the most commonly used theories of health behavior, the data suggest that these theories are missing important constructs.     

Physicalism,Qualia Inversion,And Affective States

I argue that the inverted spectrum hypothesis is nota possibility we should take seriously. The principlereason is that if someone's qualia were inverted inthe specified manner there is reason to believe thephenomenal difference would manifest itself inbehaviour. This is so for two reasons. First, Isuggest that qualia, including phenomenal colours, arepartly constituted by an affective component whichwould be inverted along with the connected qualia. Theresulting affective inversions will, given theintimate connections that exist between emotions andbehaviour, likely manifest themselves in behaviour, inwhich case the underlying phenomenal differences canbe functionally captured. Second, I argue that othersense modalities lack the structural featuresnecessary for undetectable inversion which, because oftheir analogy with colour qualia, weakens theplausibility of such an inversion in the original caseof vision.     

Noticing and commenting on what’s new: differences and similarities among 22‐month‐old typically developing children,children with Down syndrome and children with autism

Twenty 22‐month‐old typically developing children (TD), 11 children with Down syndrome (DS) and 10 children with autism (A), all functioning at a one‐ or two‐word linguistic level, were given eight series of four toys to explore. In each series, the first three toys (i.e. Trials 1–3) were identical, but the fourth toy (i.e. Trial 4) differed on a property or in identity. The children sat beside their mother and the experimenter while exploring the toys. Of interest was whether (1) the TD children would show more exploratory and communicative behavior related to the toys on Trials 1 and 4 than 2 and 3, and (2) how the response patterns of nontypically developing children would compare. The DS group showed a pattern of responding similar to that of the TD group with respect to their attention and interest in the toys, although a much lower rate of communicating with their mother. In contrast, the A group differed significantly from both other groups with respect to both the toys they found of interest and the timing of their topic initiations. Implications for observing declarative communication among children with Down syndrome and children with autism are discussed.     

Repeated exposure to violent and nonviolent pornography: Likelihood of raping ratings and laboratory aggression against women

This study examined the relatively long-term effects of repeated exposure to violent and nonviolent pornography on male' laboratory aggression against women. Self-reported likelihood of raping was also assessed as an individual differences variable that might mediate susceptibility to the effects of pornography and to ascertain whether it predicted actual aggressive behavior. Subjects were randomly assigned to the sexually violent, sexually nonviolent, or control exposure conditions. Those assigned to the sexually violent or sexually nonviolent conditions were exposed over a four-week period to ten stimuli including feature-length films and written and pictorial depictions, whereas control subjects were not exposed to any stimuli. About a week following the end of the exposure phase, subjects participated in what they believed to be a totally unrelated experiment in which aggression was assessed within a Buss paradigm. Exposure to the violent or nonviolent pornographic stimuli was not found to affect laboratory aggression. These data are discussed in terms of a recent analysis of media effects emphasizing the temporary activation of ideas in audience' minds. Likelihood of raping ratings was found to predict laboratory aggression.     

‘A good odour to breathe?’ The effect of pleasant ambient odour on human visual vigilance

The present study examined the effect of an alerting and a relaxing odour on human visual vigilance. Three groups of undergraduates (N = 54) completed a sustained visual vigilance task which required them to respond whenever a target stimulus appeared on a computer monitor. One group completed the task in the presence of an alerting odour (peppermint), another did so in the presence of a relaxing odour (bergamot) and a third group completed the task in an unscented environment. A 2×3×2 (sex×odour×diurnal preference) MANOVA was performed in order to determine group differences in response times and number of correct detections. Participants in the bergamot condition detected fewer targets correctly within 1.25 seconds of the target appearing than did those in the peppermint or no‐odour groups. Exposure to bergamot was also associated with significantly fewer correct detections in the second than in the first half of the task, when compared with the other two conditions. The results suggest that sustained exposure to a relaxing odour can impair visual vigilance. Copyright © 2001 John Wiley & Sons, Ltd.     

Why do schools of thought fail? Neo-Freudianism as a case study in the sociology of knowledge

A full account of the social production of knowledge requires an understanding of how schools of thought fail, as well as succeed. This paper offers a sociology of knowledge analysis of the collapse of neo-Freudianism as a separate school of psychoanalysis and influential intellectual current. While the existing literature stresses personal conflicts between Karen Horney, Erich Fromm and Harry Stack Sullivan as a major cause of the failure of cultural psychoanalysis, my analysis highlights the sect-like nature of Freudian institutes, the professionalizing dynamics of American psychoanalysis, the contribution of the celebrity-dominated book market and culture, and the highly controversial nature of Erich Fromm's writings and intellectual activity. Neo-Freudianism is conceptualized as a hybrid system that is a combination of a literary phenomena, intellectual movement, faction of a sect, theoretical innovation and therapy. This analysis of hybrid intellectual systems raises larger sociology of knowledge questions about schools of thought and intellectual movements. © 1998 John Wiley & Sons, Inc.     

Influence of contextual information on observers' perceptions of actors' intentions to harm others

Previous examinations of perceptions of aggressive behaviors have used static stimulus presentations (e.g., photographs or slides). This investigation examined the impact of varying amounts of geographical and temporal contextual information on observers' perceptions of actors' intentions to physically and psychologically (intimidate) harm others. Participants (51 elite ice hockey players) were randomly assigned to view one of three video-taped presentations showing eight ice hockey behaviors in either a) a dynamic mode with contextual information, b) a dynamic mode with no context, or c) a static, “freeze-frame” mode. MANOVA results showed that non-aggressive stimuli were perceived as less aggressive, and aggressive stimuli were perceived as more aggressive in dynamic presentations with context than in static presentations. Based on these findings, it is suggested that future research focussing on perceptions of aggressive behavior utilize a dynamic stimulus presentation containing context material. © 1996 Wiley-Liss, Inc.
