Self-monitoring and self-protective biases in use of consensus information to predict one's own behavior.

It is often important and useful for people to predict their own behavior in novel situations. Although theory suggests that such predictions should be based at least in part on consensus information, some past research in this area suggests that people ignore it. Previous investigators have argued that, instead of using cosensus information, people predict their own behavior on the basis of their personal histories. Two studies reported in this article demonstrate that people are willing to make use of consensus information in predicting their own behavior. However, self-monitoring is found to regulate consensus information use. High self-monitors are more responsive to complimentary consensus information than are low self-monitors, and low self-monitors are more responsive to threatening consensus information than are high self-monitors.

Real and perceived attitude agreement in social networks.

It is often asserted that friends and acquaintances have more similar beliefs and attitudes than do strangers; yet empirical studies disagree over exactly how much diversity of opinion exists within local social networks and, relatedly, how much awareness individuals have of their neighbors' views. This article reports results from a network survey, conducted on the Facebook social networking platform, in which participants were asked about their own political attitudes, as well as their beliefs about their friends' attitudes. Although considerable attitude similarity exists among friends, the results show that friends disagree more than they think they do. In particular, friends are typically unaware of their disagreements, even when they say they discuss the topic, suggesting that discussion is not the primary means by which friends infer each other's views on particular issues. Rather, it appears that respondents infer opinions in part by relying on stereotypes of their friends and in part by projecting their own views. The resulting gap between real and perceived agreement may have implications for the dynamics of political polarization and theories of social influence in general.

Generalizing the illusory correlation effect.

We used two experiments to examine the influence of one's own attitude on the perception of group attitudes. In the first experiment, subjects viewed opinion statements, supposedly made by residents of two towns, on the issue of building a local nuclear power station. One town was large and had frequently occurring statements and the other was small with infrequently occurring statements; there was an equal proportion of pro and anti statements in both towns. The prediction that subjects would perceive an illusory correlation between attitude positions similar to their own (self-relevance) and the infrequently cited (distinctive) town was supported for anti subjects only. Subsequent investigation indicated that this was due to the confounding effect of a prior expectation associating small towns with more antinuclear attitudes. Experiment 2 eliminated the variable of town size by informing subjects that towns of equal size had been more heavily or lightly sampled. Consistent with the hypotheses, both pro and anti subjects perceived an illusory correlation between their own attitude and the town providing the smaller sample, this effect increasing with attitude extremity. The consequences of these findings for the generalizability of illusory correlation explanations of stereotyping are discussed.

Contribution of stereotyped and individualized information to predictive accuracy.

The study investigated the effect of 7 types of information upon predictive accuracy. 4 of them were simple steretoypes, 3 consisted of more individualized input data. Clinicians and nursing students made predictions about 4 different Ss on selected MMPI items and bipolar traits. Predictive accuracy was found to depend little on the type and amount of information provided, stereotypes doing as well as or better than most individualized inputs. Global response sets of "Social Desirability," "Normality," and "Assumed Similarity" appeared to account for most of predictive accuracy. The judges would have significantly increased their over-all predictive accuracy, even for manifestly abnormal Ss, had they depended more heavily upon the mentioned response tendencies instead of relying on their discriminatory powers.

Correcting memory improves accuracy of predicted task duration.

People are often inaccurate in predicting task duration. The memory bias explanation holds that this error is due to people having incorrect memories of how long previous tasks have taken, and these biased memories cause biased predictions. Therefore, the authors examined the effect on increasing predictive accuracy of correcting memory through supplying feedback for actual task duration. For Experiments 1 (paper-counting task) and 2 (essay-writing task), college students were supplied with duration information about their previous performance on a similar task before predicting task duration. For Experiment 3, participants were recruited at various locations, such as fast food restaurants and video arcades, and supplied with average task duration for others before predicting how long the task would take. In all 3 experiments, supplying feedback increased predictive accuracy. Overall, results indicate that, when predicting duration, people do well when they rely not on memory of past task duration but instead on measures of actual duration, whether their own or that of others.

Knowledge-based information acquisition: Norms and the functions of consensus information.

Mill's (1872/1973) method of difference prescribes that the lay scientist should use consensus information as a control condition for the person and distinctiveness information as a control condition for the stimulus when analyzing their causal effects on the occurrence of the target event. However, in studies of information acquisition, subjects have shown a consistent preference for distinctiveness information when answering causal questions about the person, and for consensus information when answering causal questions about the stimulus. To explain this discrepancy, we distinguish between the evaluative, contrastive, and corroborative functions of consensus and distinctiveness information. In addition, we suggest that Ss seek consensus information only if it is relevant to the question posed to them, and if they cannot supply it from their own presupposed knowledge of behavioral norms. We report 4 information acquisition experiments that provide support for our analysis. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Group Cohesion, Attitude Projection, and Opinion Certainty: Beyond Interaction.

This experiment investigated the effects of group cohesiveness and estimations of consensus on opinion certainty. Members of high- or low-cohesive groups indicated their own attitude positions on 6 civic issues in a context removed from the task-oriented situation in which the groups were developed. Each person then estimated the positions of in-group or out-group members or participated in a no-projection control condition. As expected, estimation of the attitudes of either target group conferred opinion certainty onto cohesive members compared with levels found in the no-projection condition or among low-cohesive participants. Furthermore, perceptions that coworker input was facilitated and encouraged during group development mediated the effect of the experimental manipulation of cohesion on opinion certainty following attitude projection.

Pluralistic ignorance and alcohol use on campus: Some consequences of misperceiving the social norm.

Four studies examined the relation between college students' own attitudes toward alcohol use and their estimates of the attitudes of their peers. All studies found widespread evidence of pluralistic ignorance: Students believed that they were more uncomfortable with campus alcohol practices than was the average student. Study 2 demonstrated this perceived self–other difference also with respect to one's friends. Study 3 tracked attitudes toward drinking over the course of a semester and found gender differences in response to perceived deviance: Male students shifted their attitudes over time in the direction of what they mistakenly believed to be the norm, whereas female students showed no such attitude changes. Study 4 found that students' perceived deviance correlated with various measures of campus alienation, even though that deviance was illusory. The implications of these results for general issues of norm estimation and responses to perceived deviance are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Impact of Perceived Consensus on Stereotypes About Obese People: A New Approach for Reducing Bias.

In 3 experiments, the authors tested the effect of perceived social consensus on attitudes toward obese people. Participants completed self-report measures of attitudes toward obese people prior to and after manipulated consensus feedback depicting attitudes of others. In Study 1 (N=60), participants decreased negative and increased positive stereotypes after learning that others held more favorable attitudes toward obese people. In Study 2 (N=55), participants improved attitudes when they learned about favorable attitudes of obese people from an in-group versus an out-group source. In Study 3 (N=200), a consensus approach was compared with other stigma reduction methods. Social consensus feedback influenced participants' attitudes and beliefs about causes of obesity. Providing information about the uncontrollable causes of obesity and supposed scientific prevalence of traits also improved attitudes.

Mental health service utilization among African American and Caucasian mothers and fathers.

Mental health services have been routinely underutilized. This study investigated the influence of parents' gender, race, and psychopathology on perceived barriers and attitudes toward mental health utilization for themselves and for their children. A unique contribution of this study is the examination of father, mother, and child factors influencing service utilization from the parents' perspective. A total of 194 African American and Caucasian parents were recruited from the community to participate. Parents completed measures on barriers and attitudes toward treatment for themselves and for their children, history of mental health service utilization for themselves and for their children, and their own current psychological symptoms. Results indicated that 36.3% and 19.4% of parents and children, respectively, had used mental health services during their lifetime. Parents perceived fewer barriers and had more positive attitudes toward seeking services for their children than for themselves. Race and gender differences were found in parents' perceptions of barriers and attitudes toward treatment. Furthermore, barriers, attitudes, and psychopathology predicted parents' plans for future utilization of mental health services. The clinical implications of this study and directions for future research are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Fibronectin matrix regulates activation of RHO and CDC42 GTPases and cell cycle progression

This research concerned the use of mental rotation in recognizing rotated objects. Instead of the classic Shepard's paradigm in which subjects were still while observing rotated objects, here subjects had to move (or imagine moving) around stationary three-dimensional objects put in the middle of the trajectory. Thus, depending on the viewing positions, such objects were seen under six different perspectives (from 30 degrees to 180 degrees). The latter task has been thought to be closer to everyday life in which we obtain information regarding objects from their spatial properties. The results do not follow the classic rules of mental rotation of an object predicting a linear increase of the time needed to recognize distorted objects as a function of their angular displacement. They also differ from data in the literature about spatial imagery showing that access to spatial information is facilitated more when people actually move through a path than when they imagine moving. A probable explanation of this difference from the literature is discussed in relation to the particular involvement of the body in the experimental task.     

Affective and cognitive meta-bases of attitudes: Unique effects on information interest and persuasion.

The authors investigated the predictive utility of people's subjective assessments of whether their evaluations are affect- or cognition driven (i.e., meta-cognitive bases) as separate from whether people's attitudes are actually affect- or cognition based (i.e., structural bases). Study 1 demonstrated that meta-bases uniquely predict interest in affective versus cognitive information above and beyond structural bases and other related variables (i.e., need for cognition and need for affect). In Study 2, meta-bases were shown to account for unique variance in attitude change as a function of appeal type. Finally, Study 3 showed that as people became more deliberative in their judgments, meta-bases increased in predictive utility, and structural bases decreased in predictive utility. These findings support the existence of meta-bases of attitudes and demonstrate that meta-bases are distinguishable from structural bases in their predictive utility.

Intention, perceived control, and weight loss: An application of the theory of planned behavior.

Predicted success at attempted weight reduction among college women on the basis of a theory of planned behavior. 83 Ss expressed their attitudes, subjective norms, perceived control, and intentions with respect to losing weight. In addition, the extent to which they had made detailed weight reduction plans was assessed, as were a number of general attitudes and personality factors. 76 Ss were reassessed 6 wks later. In support of the theory, intentions to lose weight were accurately predicted on the basis of attitudes, subjective norms, and perceived control; perceived control and intentions were together moderately successful in predicting the amount of weight that Ss actually lost over the 6-wk period. Actual weight loss was also found to increase with the development of a plan and with ego strength, factors that were assumed to increase control over goal attainment. Other factors, such as health locus of control, perceived competence, and action control, were found to be unrelated to weight reduction.

Perception of predictive testing for Huntington's disease by young women: preferring uncertainty to certainty?

Opinions on the implications of predictive testing for Huntington's disease were evaluated in a group of 169 women (aged 21-35 years) with interest in psychosocial issues, but with no special pre-existing knowledge or training in genetics. Predictive testing for Huntington's disease (HD) is considered to be a test case for predictive testing for other late onset diseases, monogenic as well as multifactorial disorders. In the hypothetical situation of having a 50% risk for developing HD, about half of the group expressed interest in a predictive test. As to the question of giving results of predictive tests to third parties, the group would be very reluctant to inform the employer or the insurer, but not their own family. Prenatal testing for late onset diseases was considered acceptable by half of the women; only one quarter of the total group would terminate a pregnancy of a child that might develop a late onset disease. The assessment of attitudes towards predictive testing was carried out within the context of a global evaluation of perceived advantages and disadvantages of genetic counselling. The attitudes towards predictive testing were systematically associated with perceiving 'having more certainty about the future' as an advantage of genetic counselling and with rejecting 'knowing everything in advance' as a disadvantage.     

Knowledge, views, and experience of 25 women with myotonic dystrophy

Twenty-five affected women of reproductive age known to the North West Regional Genetics Family Register (NWRGFR) were interviewed. A semistructured questionnaire, completed by the interviewer, was used to assess understanding and experience of the clinical and genetic aspects of myotonic dystrophy (MD) and attitudes to prenatal diagnosis (PND). Characteristic features of MD (muscle weakness and wasting and myotonia) were well known. Knowledge of other features and complications reflected experience. All subjects were aware that MD is inherited, but only 56% (14/25) knew the risk to their own children and subjects tended to overestimate this risk. Anticipation and maternal transmission of congenital myotonic dystrophy (CMD) were often misunderstood. Almost half of the subjects (12/25) perceived themselves to be moderately or severely affected and 40% (10/25) felt that their symptoms restricted daily life. Feelings of devastation, depression, worry about the future, and guilt at the risk of transmission to their children were described. Many subjects (10/25) said that the worst aspect of MD is the risk of transmission to their children. Over half (14/25) said that the risk of transmitting MD had influenced or would influence their own reproduction. Three-quarters of subjects who felt that MD had influenced their reproductive decisions (9/12) chose to limit their family or have no children; only 25% (3/12) requested PND. Subjects felt that the lack of information concerning clinical severity made PND for MD difficult to consider.     

Attitudes, polarization, and diagnosticity: Exploring the effect of affect.

Examines the various judgmental effects of attitude intensity or commitment. 28 feminist and 26 nonfeminist undergraduates estimated the prevalence of both pro- and antifeminist attitudes in various segments of the population. They then estimated the prevalence of various personality traits and demographic characteristics among others with either pro- or antifeminist attitudes. In accord with a "false consensus" hypothesis, both S groups perceived profeminist attitudes to be more common among all population groups. In addition, however, committed Ss viewed the population as significantly more polarized on the women's rights issue. Relative to the remaining Ss, committed feminists overestimated the prevalence of both pro- and antifeminist attitudes. Although both S groups found information concerning others' position on women's rights to be highly diagnostic of personality traits and attitudes, committed feminists saw this information as significantly more diagnostic for both pro and anti others. Implications for both attribution and attitude theories are discussed. (20 ref) (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Awareness of influences on one's own judgments: The roles of covariation detection and attention to the judgment process.

Forty-eight actor participants examined profiles of target persons and judged how much they would like each target. Initial-attention actors were instructed before judging any of the profiles to attend to how target factors influenced their liking judgments. Delayed-attention actors received these instructions after judging the first block of profiles and before judging the second. No-attention actors did not receive these instructions at all. After judging the target profiles, actors estimated how each of several target factors had influenced their liking judgments. Access to covariation information greatly increased the accuracy of observers' causal reports. Covariation detection appeared to make less of a contribution, however, to actors' own causal reports, which displayed a substantial level of accuracy even after we controlled statistically for the possible contributions of covariation detection and shared theories. Contrary to expectations, the attention instructions actually decreased the accuracy of actors' self-reports for the first block of judgments but had no effect on accuracy for the second block of judgments. Results show that some form of privileged self-knowledge contributed to the accuracy of actors' causal reports. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Studying intergenerational transmission of eating attitudes and behaviors: Methodological and conceptual questions.

Associations between parent and child attitudes and behaviors related to eating and weight were examined among college-age men and women and their mothers and fathers (ns?=?44, 47, 87, and 66, respectively). Parent attitudes and behaviors were assessed from the perspective of the parent and the student, and 2 pathways of influence were examined: modeling and direct criticism. In general, students' attitudes and behaviors were more strongly related to perceptions of their parents rather than to parents' own self-reports. There was more support for perceived direct criticism as a pathway of influence, particularly for daughters. Perceived criticism about eating and appearance had large associations with student attitudes and behaviors. Weight loss behavior was related to perceived criticism among daughters and to perceived paternal eating attitudes among sons. Results highlight important methodological and conceptual questions for intergenerational research. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Student/instructor attitude similarity, student ratings, and course performance.

Investigated the validity of student ratings of instructional effectiveness by exploring the relations among student ratings, course performance, and the perceived attitude similarity of students and their instructors. 349 college students enrolled in 22 classes first rated instructor effectiveness on a 28-item rating form and then rated their own attitudes plus instructor attitudes on an attitude scale adapted from D. Byrne (1971). Another 296 college students enrolled in 19 classes rated instructor effectiveness and then their own attitudes plus instructor attitudes on an attitude scale adapted from F. E. Hofman and L. Kremer (see record 1980-33352-001). For both S groups, official end-of-term grades were also collected. Consistent with prior research, modest correlations were found between student ratings and perceived attitude similarity. There was also a modest relation between similarity and course grades. These relations were greatly reduced (56.2 and 44.5%, respectively) when the large influence of instructors on ratings and achievement was removed. Findings fail to support the claim that perceived attitude similarity is a substantial source of bias in student ratings. (13 ref) (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Clinical teachers as humanistic caregivers and educators: perceptions of senior clerks and second-year residents

BACKGROUND: The acquisition and nurturing of humanistic skills and attitudes constitute an important aim of medical education. In order to assess how conducive the physician-learning environment is to the acquisition of these skills, the authors determined the extent to which clinical teachers are perceived by their trainees as humanistic with patients and students, and they explored whether undergraduate and graduate students share the same perceptions. METHODS: A mail survey was conducted in 1994/95 of all senior clerks and second-year residents at Laval University, University of Montreal and University of Sherbrooke medical schools. Of 774 trainees, 259 senior clerks and 238 second-year residents returned the questionnaire, for an overall response rate of 64%. Students' perceptions of their teachers were measured on a 6-point Likert scale applied to statements about teachers' attitudes toward the patient (5 items) and toward the student (5 items). RESULTS: On average, only 46% of the senior clerks agreed that their teachers displayed the humanistic characteristics of interest. They were especially critical of their teachers' apparent lack of sensitivity, with as many as 3 out of 4 declaring that their teachers seemed to be unconcerned about how patients adapt psychologically to their illnesses (75% of clerks) and that their teachers did not try to understand students' difficulties (78%) or to support students who have difficulties (77%). Compared with the clerks, the second-year residents were significantly less critical, those with negative perceptions varying from 27% to 58%, 40% on average. Except for this difference, their pattern of responses from one item to another was similar. INTERPRETATION: This study suggests the existence of a substantial gap between what medical trainees are expected to learn and what they actually experience over the course of their training. Because such a gap could represent a significant barrier to the acquisition of important skills, more and urgent research is needed to understand better the factors influencing students' perceptions.
