This research investigated two competing explanations of the similarity effect: Byrne’s (1971) reinforcement model and the information processing perspective. A meta-analysis of 240 laboratory-based similarity studies explored moderators important to the similarity effect, including set size, proportion of similarity, centrality of attitudes, and information salience. Results indicated effects for proportion of similarity, centrality of attitudes, and information salience, and were largely…

We describe a model for understanding interpersonal attraction in which attraction can be understood as a product of the initial evaluations we make about others. The model posits that targets are

The effect of actual and inferred value similarity on interpersonal liking

This research examined whether value similarity between a person and another individual elicits more positive attitudes towards the individual. Chapter 1 provides a review of the interpersonal

The Similarity and Liking Effects on Interpersonal Attraction: A Test of the Two-Dimensional Cognitive Model

In the two-dimensional model of interpersonal attraction, cognitively evaluated respect for capacity of and trust in willingness to facilitate goals/needs of each other have been postulated to be

Effectance Motivation and Self-Validation in Interpersonal Attraction from Attitude Similarity

Effectance motivation -- a will for certainty and a feeling of being able to know and predict -- was proposed in the 1960s as the mechanism underlying the well-known attitude similarity effects on

The Similarity-Attraction Link: Sequential Versus Parallel Multiple-Mediator Models Involving Inferred Attraction, Respect, and Positive Affect

We tested the hypothesis that the attitude similarity effect spreads sequentially through positive affect, respect, and inferred attraction to attraction. In Experiment 1, participants received

Causal role of trust in interpersonal attraction from attitude similarity

The most popular method for investigating the mediation of the similarity-attraction link by trust involved first the manipulation of attitude similarity between the partner and the participant and

On the importance of trust in interpersonal attraction from attitude similarity

Trust has been identified as a key factor in relationship development and appreciation of group members. However, trust has not been previously considered as a reason for attitude similarity to

Attitude similarity and attraction: Validation, positive affect, and trust as sequential mediators

Effectance motivation—an urge for certainty and a feeling of being able to know, predict, and control one's environment—was initially proposed as the mechanism underlying attitude similarity effects

Positive Affect Moderates Partner's Liking Effects on Trust and Attraction

Attitude similarity effects on attraction seem to be mediated sequentially by positive affect, inferred attraction, and trust. That is, the first two mediators influence each other in building trust,



Attitudes and Attraction: A Developmental Study of the Similarity-Attraction and Dissimilarity-Repulsion Hypotheses

Contrasting predictions ofByrne's similarity-attraction hypothesis and Rosenbaum's dissimilarity-repulsion hypothesis were tested with 7-, 11-, 15-, and 21-year-olds in Singapore. The study included

On the importance of cognitive evaluation as a determinant of interpersonal attraction.

Three studies examined a model of attraction in which the cognitive evaluation of the target individual was the primary determinant of interpersonal attraction and provided empirical and theoretical support for the uniqueness of interpersonal attractions from cognitive evaluation.

Effects of Affective Value and Similarity on Attraction.

Empirical test results showed significant main effects for both affective value and similarity indicating that similarity can have direct effects on attraction.

Is actual similarity necessary for attraction? A meta-analysis of actual and perceived similarity

To evaluate the impact of actual and perceived similarity on interpersonal attraction, we meta-analyzed 460 effect sizes from 313 laboratory and field investigations. Results indicated that the

The similarity–attraction relationship revisited: divergence between the affective and behavioral facets of attraction

In contemporary attitudes-and-attraction research, attraction has been viewed as a multidimensional construct. Moreover, the effects of dissimilar and similar attitudes have been shown to vary with

Evaluations, Attitude Similarity, and Interpersonal Attraction: Testing the Hypothesis of Weighting Interference Across Responses

The greater effect of negative than positive stimuli on judgments—the positive-negative asymmetry (PNA)—is rather pervasive. However, the effects of the valence of evaluations of the participant by

Salience of similarity awareness and attraction: A comparison of balance vs reinforcement predictions

Factor analyses of the rating data showed that attraction and similarity ratings loaded on different factors, indicating that perceived similarity does not necessarily mediate attraction, and suggests that a restricted balance model may be viable.

Similarity and Attraction: A Longitudinal Study

Although it is generally acknowledged that psychological similarity influences the development of same-sex friendship, empirical studies often fail to delineate the differential impact of attitude,

The impact of discussion on interpersonal attraction

The effects of similarity, format of presentation, and choice of topics for attitude exchange on interpersonal-attraction ratings was investigated in this study. Subjects met and exchanged views on
