Assumed similarity measures as predictors of team effectiveness.

"The present investigations test the hypothesis that group effectiveness is related to the interpersonal perceptions which members of the group have toward one another. Interpersonal perceptions were measured by correlating identical questionnaires which subjects were instructed to fill out (a) describing themselves, (b) predicting the responses of their preferred co-worker, and (c) predicting the responses of their rejected co-worker." The assumed similarity score of the team's most preferred work companion was found to be negatively correlated with a criterion of team effectiveness.

Positive and negative opinion modeling: The influence of another's similarity and dissimilarity.

Modeling research that has focused on the effects of observing similar others appears to have underestimated the influence of observing dissimilar others. Two experiments demonstrated that observing a model express liking for a piece of music induced more favorable opinions of the music (positive modeling) when the model was similar to the participant observer in relevant opinions, and more negative opinions (negative modeling) when the model was dissimilar to the participant in relevant opinions. Of note, this pattern was more pronounced when participants also believed their general backgrounds were dissimilar rather than similar to that of the model. Underlying social comparison processes and the mediational role of participants' liking of the model are considered. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Subjective certainty and resistance to change.

"Ss were led to believe that they were exchanging numbered counters with one another, through a messenger, to the end that all six members could achieve simultaneous solutions to a problem… . The crucial determination was whether or not S would break his own solution to yield to a simulated request from another group member for one of the numbers he was using… . evidence is used to support an interpretation of yielding to group pressure which takes account of Ss' perceptual modes of organizing complex, ambiguous situations."

Group similarity, public self-awareness, and opinion extremity: A social projection explanation of deindividuation effects.

Suggests that when a person reacts to an opinion, he/she will project an identical reaction onto similar others—in effect, self-generating a consensus that serves to polarize the opinion. Public self-awareness is assumed to individuate and to moderate opinions only when projection is disrupted. Two experiments, with 169 undergraduates, tested derivations from this theory. Exp I varied self-confidence induced by ability feedback (positive vs negative) and self-awareness induced by being or not being observed by camera. Results show that heightened self-awareness moderated opinions regardless of the S's initial level of self-confidence. Exp II varied group similarity (similar, dissimilar, or no information) and level of self-awareness (heightened vs low) using a 3?×?2 design in which opinion extremity was measured. Results confirm the prediction that opinions fluctuate systematically (polarize and moderate) with level of self-awareness only when the person is in a similar group. Low self-awareness tended to polarize opinions, whereas heightened self-awareness moderated them. The assumed direct relation between opinion intensity and behavioral extremity is discussed within the context of projection-predicted intensification effects of prosocial behavior.

On doubting and certainty

Eggs from four species of aquatic birds inhabiting waterways of the Lake St. Clair region were collected in 1973 and analyzed for mercury. Species analyzed were mallard ducks (Anas platyrhynchos), common terns (Sterna hirundo), black-crowned night herons (Nycticorax nycticorax), and great egrets (Casmerodius albus). Mallard eggs contained relatively low residue levels, less than 0.05-0.26 ppm, and common tern eggs contained the highest residues, ranging up to 1.31 ppm. Mercury levels in the eggs were appreciably lower than those in the same species in 1970. The declines are attributed to the 1970 restrictions placed on industrial discharges of mercury into the St. Clair and Detroit Rivers.     

Individual and situational differences in desire for certainty.

The correlation was determined between Ss' extremity of response on several attitude and judgment instruments and scores on a test of desire for certainty. "Significant correlations were obtained between response extremity and test scores, suggesting that individual differences in desire for certainty are consistent from one measure to another." In another study it was shown that the strength of the desire for certainty can be increased and decreased by situational influences. 24 references.

Communicator attractiveness and opinion change.

Presented a tape recorded persuasive communication to 120 college and high school students while a photograph of a man identified as the speaker was projected onto a screen. 3 groups of ss listened to the communication in the presence of either (a) a photograph of an attractive communicator, (b) a photograph of an unattractive communicator, or (c) no photograph at all. 2 additional groups of ss did not listen to the communications, but filled out the postcommunication questionnaire only in the presence of (a) the photograph of the attractive speaker, or (b) the photograph of the unattractive speaker. Attractive male communicators were more persuasive that unattractive male or unpictured communicators. This effect was independent of differences in perceived expertness or trustworthiness of the communicator. Explanations in terms of distraction, contiguous pleasure, and liking are discussed.

Public opinion and nuclear war.

Notes that public opinion research shows that a majority of respondents in the US and several European countries favor a reduction in nuclear armaments and a nuclear freeze as a 1st step in that direction and that there has been a marked increase in involvement by psychologists and psychological organizations toward this end. It is argued that the present situation is propitious for the active participation of psychologists. Possible contributions appropriate for psychologists, ways of making these contributions effective, and the desirability of associating such activities, whenever possible, with those of colleagues in other parts of the world are discussed.

Unpacking attitude certainty: Attitude clarity and attitude correctness.

Attitude certainty has been the subject of considerable attention in the attitudes and persuasion literature. The present research identifies 2 aspects of attitude certainty and provides evidence for the distinctness of the constructs. Specifically, it is proposed that attitude certainty can be conceptualized, and empirically separated, in terms of attitude clarity (the subjective sense that one knows what one's attitude is) and attitude correctness (the subjective sense that one's attitude is correct or valid). Experiment 1 uses factor analysis and correlational data to provide evidence for viewing attitude clarity and attitude correctness as separate constructs. Experiments 2 and 3 demonstrate that attitude clarity and attitude correctness can have distinct antecedents (repeated expression and consensus feedback, respectively). Experiment 4 reveals that these constructs each play an independent role in persuasion and resistance situations. As clarity and correctness increase, attitudes become more resistant to counterattitudinal persuasive messages. These findings are discussed in relation to the existing attitude strength literature.

Personality similarity and friendship.

Using the Edwards Personal Preference Schedule, "personality similarity or similarity of affect needs and of ways of expressing and receiving affect" was found to be a significant factor in interpersonal attraction. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Effects of commitment and certainty upon interest in supporting information.

A field experiment was conducted to test hypotheses derived from a theory concerning interest in information about the relative merits of alternative actions. After college men stated a position on an issue, they indicated their interest in reading articles favoring each side of the issue and also rated how certain they were their position was best. Some were told their position would be publicized, others that it would be kept completely private. In accordance with the hypotheses, when they were publicly committed to a position, the less certain they were it was the best position the more they preferred information supporting the position; when they were not committed, the more certain they were the more they preferred supporting information (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Interpersonal attraction and attitude similarity.

It "was hypothesized that (a) a stranger who is known to have attitudes similar to those of the subject is better liked than a stranger with attitudes dissimilar to those of the subject, (b)… is judged to be more intelligent, better informed, more moral, and better adjusted… and (c)… is evaluated more positively on… four [other] variables." The first 2 hypotheses were confirmed. From Psyc Abstracts 36:04:4GE13B. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Understanding and similarity in marriage.

The following conclusions appear to be justified: (1) There is no evidence that happiness in marriage is a function of understanding the mate or is related to the similarity of selves of the mates. (2) Evidence indicates that marital happiness is associated with similarity of self perceptions of the mates. (3) Husbands and wives are no more similar in self perceptions than randomly paired men and women. (4) Marital happiness is related to the conformity of men to self perceptions of their sex.

Models of similarity and intensity.

Reviews the development of content models of similarity and their foundations in work on unidimensional similarity and multidimensional ratio estimation. The content and the distance models are discussed from several points of view, noting that with few exceptions, the distance model has a clear theoretical advantage. It is concluded that at present the content models may have a limited applicability in cases with only qualitative variations and cluster structures or dimensional variation of a nonradex kind.

Respects for similarity.

Reviews the status of similarity as an explanatory construct with a focus on similarity judgments. For similarity to be a useful construct, one must be able to specify the ways or respects in which 2 things are similar. One solution to this problem is to restrict the notion of similarity to hard-wired perceptual processes. It is argued that this view is too narrow and limiting. Instead, it is proposed that an important source of constraints derives from the similarity comparison process itself. Both new experiments and other evidence are described that support the idea that respects are determined by processes internal to comparisons.

Sexual preference similarity, attitude similarity, and perceived counseling credibility and attractiveness.

84 17–66 yr old homosexual men identified as holding either an activist or a nonactivist stance on gay advocacy rated the counselor's credibility and attractiveness on the Counselor Rating Form after listening to an audiotape-recorded segment of a counseling interview between a male counselor and a male client expressing sexual preference concerns. Ss heard the same counseling interaction except for counselor responses to 2 client questions, one related to counselor sexual preference and one related to counselor stance on gay advocacy. The counselor was rated more Expert, Trustworthy, and Attractive when he stated a sexual preference for men than when he stated a sexual preference for women or refrained from stating a sexual preference. Attractiveness ratings were a function of attitude similarity between the counselor portrayed on the tape recording and Ss in the study.

Perceived similarity and the projection of similarity: The influence of valence.

Some of the implications of Heider's concept of balance were investigated using 104 students as Ss. Based upon their responses to the Revised Allport-Vernon Scale of Values, partially completed test booklets were prepared incorporating different degrees of similarity to each Ss' original answers. The Ss were required to complete them in the way the hypothetical person had. The results confirmed the hypotheses. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Attitude intensity, importance, and certainty and susceptibility to response effects.

Changes in attitude question form, wording, and context have repeatedly been shown to produce change in responses. It is often assumed that such response effects are less pronounced among individuals whose attitudes are intense, personally important, or held with great certainty. We report the results of 27 experiments conducted in national surveys designed to evaluate this hypothesis. Measures of attitude intensity, importance, and certainty were found not to differentiate individuals who show response effects from those who do not. We discuss possible explanations for these counterintuitive findings. (PsycINFO Database Record (c) 2010 APA, all rights reserved)
