Biological explanations and stigmatizing attitudes: using essentialism and perceived dangerousness to predict antistigma intervention effectiveness

The theory of essentialism suggests that biological explanations of stigmatized behavior may not be effective at decreasing stigmatizing attitudes. The effects of biological explanations on stigmatizing attitudes were the topic of two experiments. In the first experiment, participants (N = 243) perceived a biological explanation as a less effective in relation to dangerousness and social distancing attitudes about mental illness than about homosexuality. The second experiment (N = 113) compared the effect of biological and free choice explanations on stigmatizing attitudes about abnormal sexual and eating behaviors. The results indicated that a biological explanation increased belief in essentialism and was most effective for attitudes related to anger and blame. These results suggest that the effectiveness of biological explanations as an antistigma tool varies according to the attitude and stigmatized group.     

Many stimuli are frightening,but some are more frightening than others: The contributions of preparedness,dangerousness, and unpredictability to making a stimulus fearful

The nonrandom distribution of situational fears has been explained by evolutionary survival relevance of specific fears. Thirty-eight stimuli were taken from the literature on preparedness and were scored on fearfulness, objective dangerousness, and spatiotemporal unpredictability by three separate groups of students. The same items were scored on survival relevance by 15 biologists. Fearfulness of cues significantly correlated not only with survival relevance but also, and even more strongly, with dangerousness and unpredictability. While the fear/survival relevance association virtually disappeared when the unpredictability contribution was partialed out, the fear/unpredictability correlation was only marginally affected when controlling for survival relevance. This suggests that nonrandomness of feared stimuli may result from the spatiotemporal unpredictability that is attributed to these stimuli. The current practice of using snakes and spiders as phobia-relevant, and flowers and mushrooms as neutral, cues was not justified by the ratings of the 15 independent experts.This study was supported in part by a grant from the Dutch Organization for Fundamental Research (ZWO/Psychon, 560-268-001).     

Interpreting claims in offender profiles: the role of probability phrases,base‐rates and perceived dangerousness

Offender profilers use verbal and numerical probability expressions to convey uncertainty surrounding claims made about offender's characteristics. No previous research has examined how these expressions might affect the recipient's interpretation of the information. Seventy participants completed an online questionnaire and results showed a diverse range of interpretations of these uncertainty expressions. Moreover, characteristic base‐rates and dangerousness affected the perceived likelihood of the profiling claim, such that increased base‐rates and perceived dangerousness resulted in an increased perception of the claim being likely. Perceived likelihoods also depended on the framing of characteristics as well as the framing of the claim itself. Finally, where claims involved presenting a characteristic qualified by a low probability these claims were interpreted as more likely than not to be present. These findings have practical implications for profilers and more general theoretical implications for the study of risk perception. Copyright © 2008 John Wiley & Sons, Ltd.     

Uncontrollability and unpredictability in post-traumatic stress disorder: an animal model.

The disturbances observed in animals subjected to unpredictable and uncontrollable aversive events resemble post-traumatic stress disorder (PTSD) symptoms and thus may constitute an animal model of this disorder. It is argued that the similarity between animals' symptoms and those of trauma victims may reflect common etiological factors. Relevant experiments in which animals exhibit generalized fear and arousal, discrete fear of a conditioned stimulus (CS), analgesia, and avoidance are reviewed with the view that these manifestations may be analogous to the PTSD symptom clusters of persistent arousal, reexperiencing, numbing, and avoidance, respectively. Finally, animal paradigms are suggested to test the validity of the model and specific hypotheses are derived from the animal literature regarding trauma variables that are predictive of particular PTSD symptom clusters.     

Coin value and perceived size: a longitudinal study.

Decimalization of the Irish currency presented an opportunity to study the perceived size of coins as they were introduced or withdrawn and to examine the accentuation of differences between coins. Estimates were obtained of the sizes of 4 coins from 478 subjects in 3 groups tested at different times: just after decimalization, 2, or 3 yr. later. A newly introduced coin was significantly underestimated in size at first but came to be significantly overestimated later, while all familiar coins were always significantly overestimated. The amount of overestimation of a coin depended on its value, not its size, leading to an accentuation of the difference between any two coins if the larger coin was also the more valuable but sometimes to the opposite if the smaller coin were of higher value than the larger member of the pair.     

生命早期环境不可预测性对过度进食的影响:基于生命史理论

在生命史理论的视角下,本研究通过两个研究揭示了生命早期环境不可预测性对过度进食的影响及其作用机制。研究1招募处于生命早期阶段的91名初中生(年龄12～14岁),采用饱食进食(Eating in the absence of hunger,EAH)范式,结果发现生命早期环境不可预测性能够显著正向预测个体饱食状态下的高热量食物选择(即过度进食);研究2招募新冠病毒疾病(COVID-19)爆发背景下301名武汉市居民(高死亡威胁组)和179名其他省市居民(控制组)(年龄18～60岁)为被试,通过问卷法回溯性地测量生命早期环境不可预测性并探究其影响当前过度进食的机制,结果发现生命早期环境不可预测性通过生命史策略的中介作用间接影响过度进食。同时,死亡威胁(新冠病毒疫情)扩大了环境不可预测性通过生命史策略间接影响过度进食的效应,而社会支持则能缓冲这一效应。研究结果为COVID-19背景下和灾后居民的健康进食干预提供了依据。     

Race and brain weight: a note on J.P. Rushton's conclusions

Rushton's (1988) reinterpretation of recent research on brain weight one-sidedly emphasizes the findings of heavier brain weight in whites than in blacks and neglects to comment on a larger difference found between men and women. Rushton explicitly used brain size as indicator of intelligence. His implicit conclusion that women are less intelligent than men is not supported by empirical research.

Autokinetic movement in geometric illusions: a note.

Four static geometrical illusions were presented in an autokinetic movement situation. 50 Ss saw each form four times. Of the total responses, 36% were no-movement responses while 37% of the time the total figure was seen as moving. The meaning 27% of the responses involved apparent movement in only a part of the figure. In general, the elements seen as moving are the parts misperceived in the static geometrical illusion.     

A note on notes: note taking and containment

In extreme situations of massive projective identification, both the analyst and the patient may come to share a fantasy or belief that his or her own psychic reality will be annihilated if the psychic reality of the other is accepted or adopted (Britton 1998). In the example of' Dr. M and his patient, the paradoxical dilemma around note taking had highly specific transference meanings; it was not simply an instance of the generalized human response of distracted attention that Freud (1912) had spoken of, nor was it the destabilization of analytic functioning that I tried to describe in my work with Mr. L. Whether such meanings will always exist in these situations remains a matter to be determined by further clinical experience. In reopening a dialogue about note taking during sessions, I have attempted to move the discussion away from categorical injunctions about what analysis should or should not do, and instead to foster a more nuanced, dynamic, and pair-specific consideration of the analyst's functioning in the immediate context of the analytic relationship. There is, of course, a wide variety of listening styles among analysts, and each analyst's mental functioning may be affected differently by each patient whom the analyst sees. I have raised many questions in the hopes of stimulating an expanded discussion that will allow us to share our experiences and perhaps reach additional conclusions. Further consideration may lead us to decide whether note taking may have very different meanings for other analysts and analyst-patient pairs, and whether it may serve useful functions in addition to the one that I have described.     

Conscientiousness, perceived risk, and risk-reduction behaviors: a preliminary study.

Participants (N = 343) from an Oregon community completed surveys at baseline, 3 months, and 12 months to assess personality, the perceived health risk of radon in combination with smoking, and changes in smoking behavior. Conscientiousness predicted instituting a more restrictive household smoking rule (p < .01), and perceived risk predicted reduction in cigarettes smoked per day for men (p < .001). Perceived risk predicted a reduction in the proportion of cigarettes smoked in the home for those who had high (p < .05) but not low or moderate levels of Conscientiousness, a dimension in one personality model. The results demonstrate the importance of Conscientiousness in the prediction of health behavior, particularly behavior that affects others as well as oneself.     

The measurement of criminal dangerousness as a personality construct: further validation of a research index

The validity of an index measuring criminal dangerousness was further evaluated by determining whether it could discriminate among prisoners committing violent crimes at three levels of severity. The index score was a multiplicative product of an antisocially score and an IQ score, with high antisocially and low IQ reflecting greater dangerousness. Comparison of index scores for men committing murder (most severe); robbery and rape (intermediate severity); and assault, child molestation, and manslaughter (least severe) revealed a significant monotonic increase in dangerousness scores as increasingly severe crimes were considered. Several recommendations for the measurement of criminal dangerousness were offered.
