Social and medical influences on attributions and evaluations of chronic pain

Abstract

Previous research suggests that judgments of pain are subject to social influences, including characteristics of the person in pain, the judge, and the social context in which the judgment occurs. In this experiment, eight vignettes describing a person with chronic low back pain were varied as a function of patient ethnicity (Caucasian vs African-American), litigation status (litigant vs non-litigant), and medical evidence (strong vs weak). Participants (N= 116) read vignettes, made attributions of causality for the person's pain and disability, and evaluated the severity of the pain syndrome. Pain and disability were perceived as more legitimate when the person in pain was a non-litigant and when medical evidence was strong. Evaluations of syndrome severity were more extreme when evidence was strong. A three-way interaction indicated that judgments may have been influenced by ethnic stereotypes. These findings substantiate the influence of social variables in judgments of persons with pain.     

Voice pitch preferences of adolescents: Do changes across time indicate a shift towards potentially adaptive adult-like preferences?

An evolutionary approach to attractiveness judgments emphasises that many human trait preferences exist in order to assist adaptive mate choice. Here we test an adaptive development hypothesis, whereby voice pitch preferences indicating potential mate quality might arise or strengthen significantly during adolescence (when mate choice becomes adaptive). We used a longitudinal study of 250 adolescents to investigate changes in preference for voice pitch, a proposed marker of mate quality. We found significantly stronger preferences for lower-pitched opposite-sex voices in the older age group compared with the younger age group (using different sets of age-matched stimuli), and marginally increased preferences for lower-pitched opposite-sex voices comparing within-participant preferences for the same set of stimuli over the course of 1 year. We also found stability in individual differences in preferences across adolescence: controlling for age, the raters who had stronger preferences than their peers for lower-pitched voices when first tested, retained stronger preferences for lower-pitched voices relative to their peers about 1 year later. Adolescence provides a useful arena for evaluating adaptive hypotheses and testing the cues that might give rise to adaptive behaviour.     

Interpersonal Judgments: Moral Responsibility and Blame

A deterministic perspective, believing choices are a function of hereditary and environmental factors, could theoretically impact perceived moral responsibility and lead to decreased blame in judging others. However, little consistent support has been found relating individual differences in deterministic attitudes to blame/tolerance for others. Perhaps, though, providing information regarding past background hardships affecting an individual's current lifestyle could potentially mediate harsh moralistic judgments of that individual. In the two studies reported here, we further explored the relation of free will/determinism scales to attitudes toward others as well as the effect of manipulating background information on the assignment of blame. As in previous research, little support was found for the relation of deterministic attitudes to tolerance toward others. However, judgments following manipulated information about hypothetical target persons supported the conclusion that target individuals are blamed less and given more sympathy if more information related to previous hardships is provided. In addition, in the second study perceived similarity to a target individual was associated with decreased blame/greater sympathy for a target with alcohol abuse problems.     

Children's Trait and Emotion Attributions in Socially Ambiguous and Unambiguous Situations

Children's attributions about story characters in ambiguous and unambiguous social situations were assessed. One hundred and forty-four 6–7-year-olds and 10–11-year-olds heard about actors who slighted a recipient intentionally or for an undetermined reason and then made causal attributions about the events, an emotion attribution about the recipient, and global personality attributions about the actors and recipient. Relations between perceived self-competence and attribution style were also assessed. Participants were more likely to make negative causal attributions in the unambiguous condition and with increasing age. Older girls and younger boys were more likely than other groups to attribute negative emotions to the recipient. Overall, participants perceived recipients positively and actors negatively. Perceived self-competence was positively correlated with actor attributions, although these differed by age and gender. Implications for children's psychosocial adjustment are discussed.     

Alternative Lens Model Equations for Dichotomous Judgments about Dichotomous Criteria

The Brunswik lens model typically represents a judge's accuracy using parameters derived from linear regression. This is not optimal if the judgment or the ecological criterion is dichotomous. Alternative approaches, modeling dichotomies using logistic regression, or linearizing judgments with confidence ratings, have not been compared with the same data. Four techniques for deriving lens model equation parameters were compared: (i) linear and (ii) logistic regression applied to dichotomous patient outcomes and judgments; (iii) linear regression with confidence‐adjusted judgments but dichotomous patient outcomes; and (iv) a hybrid with a linear model of the confidence‐adjusted judgments and a logistic model of the patient outcomes. Judgment accuracy (r_a) was slightly higher with confidence adjustment of the categorical judgments. The logistic lens model accounted for a higher proportion of r_a than the linear lens model; the confident‐linear and hybrid lens models were intermediate. For up to a quarter of participants, different methods identified different cues as most important. Display condition differences in achievement r_a and in lens model components are similar with all lens model methods. Each of the three alternative lens model equation methods improves on the linear lens model equation's decomposition of the accuracy of dichotomous judgments. Confidence adjustment improves achievement although it requires additional work from the subjects. The logistic lens model equation explains the highest proportion of achievement, but with a small stimulus set, it is more vulnerable to cue intercorrelations than either the linear or the confident linear lens model equation.

The influence of visual mental imagery size on metamemory accuracy in judgment of learning

Many studies have found the font size of to-be-remembered words has a significant influence on judgments of learning (JOLs). However, few studies have investigated whether JOLs are affected by the mental imagery size of to-be-remembered words, even when the font sizes themselves are kept identical in study materials. This study investigated whether the visual mental imagery size influences the participants’ JOLs and what the underlying mechanisms are. In Experiments 1 and 2, participants learned words with identical font sizes, mentally generated large or small imageries and then made JOLs. We found that JOLs under the large imagery condition were significantly higher than those under the small imagery condition, but actual recall performance exhibited no significant difference. In Experiment 3, participants pressed a button immediately after mental imagery generation and showed that it took significantly longer to generate large imageries than to generate small imageries, and the difference in JOLs between two conditions was no longer significant. In Experiment 4, we used a questionnaire to investigate the contribution of beliefs and found that participants believed large imageries were easier to remember. These findings indicate that imagery size has a significant impact on JOLs, in which beliefs may play a leading role.     

Getting at the source of distinctive encoding effects in the DRM paradigm: evidence from signal-detection measures and source judgments

Studying Deese–Roediger–McDermott (DRM) lists using a distinctive encoding task can reduce the DRM false memory illusion. Reductions for both distinctively encoded lists and non-distinctively encoded lists in a within-group design have been ascribed to use of a distinctiveness heuristic by which participants monitor their memories at test for distinctive-task details. Alternatively, participants might simply set a more conservative response criterion, which would be exceeded by distinctive list items more often than all other test items, including the critical non-studied items. To evaluate these alternatives, we compared a within-group who studied 5 lists by reading, 5 by anagram generation, and 5 by imagery, relative to a control group who studied all 15 lists by reading. Generation and imagery improved recognition accuracy by impairing relational encoding, but the within group did not show greater memory monitoring at test relative to the read control group. Critically, the within group’s pattern of list-based source judgments provided new evidence that participants successfully monitored for distinctive-task details at test. Thus, source judgments revealed evidence of qualitative, recollection-based monitoring in the within group, to which our quantitative signal-detection measure of monitoring was blind.     

Reconsidering research on self-humanizing: The importance of mean comparative judgments

Self-humanization is defined as the tendency to view oneself as more essentially human than others. Researchers have claimed that people attribute human nature traits more strongly to themselves than to others, but not uniquely human traits. In this article we suggest that such claims are based on the misinterpretation of results. Most studies have not presented mean comparative judgments, making it impossible to determine whether people thought they possessed characteristics less strongly or more strongly than the average person. We found that people (N = 256) in Poland, Italy, and Korea perceived themselves as possessing desirable human nature and uniquely human characteristics more than others, as possessing undesirable uniquely human traits less than others, and as similar to others in terms of undesirable human nature characteristics. It seems that being more human than others means possessing some traits more than others and possessing some traits less than others.
