Avoidance behavior and perceived arousal

Previous investigations of the effects of bogus arousal feedback on approach toward an aversive stimulus have failed to separate two conceptual issues: (1) the influence of perceived anxiety on approach behavior, and (2) the degree to which perceptions of decreased anxiety are central to systematic desensitization. The present research deals with only the first of these issues. The procedure required each subject to attach a microphone to his or her chest and approach a snake. Bogus heartbeat feedback was presented concurrently with the subject's approach. In Experiments 1 and 2, self-reported snake phobics approached more with a constant than with an accelerating heartbeat. Nonphobics in Experiment 2 were not systematically influenced by the feedback. In Experiment 3, subjects with moderate fear, but who had stated that they could pick up a snake, behaved like the previously tested nonphobics; moderate fear subjects who had stated uncertainty about their ability to handle a snake behaved like previously tested phobics. In no case did postexperimental self-rated fear of snakes yield a difference between feedback conditions. The results are discussed in terms of the attributional analysis of emotional behavior.     

The attraction–similarity model and dating couples: Projection,perceived similarity,and psychological benefits

According to the attraction–similarity model, relationship quality leads to perceptions of partner–self similarity. Relationship quality and perceived similarity then provide psychological benefits for the perceiver. Across 3 studies, relationship quality positively predicted perceptions of similarity. Study 1 indicated that for moderate, but not low, relationship‐relevant traits, individuals projected the self onto the dating partner as a way of perceiving similarities. In Study 2, priming high, as opposed to low, relationship quality led to greater perceived similarity on the moderately relevant traits. Study 3 indicated greater perceived similarity between self and dating partner than between self and average same‐gender student on the moderately relevant traits. Relationship quality and perceived similarity with the dating partner on the moderately relevant traits also predicted psychological benefits.     

Gender-role's attitude, perceived similarity, and sexual prejudice against gay men

Two hundred and twenty-six heterosexual participants (115 women and 111 men) were asked to indicate their attitude toward gender-roles, their perceived similarities with gay men, and their attitude toward gay men (i.e., sexual prejudice). As expected, male participants showed more sexual prejudice than female participants, and perceived dissimilarities were related to a greater sexual prejudice. Support for gender-roles was related to sexual prejudice for male participants, but not for female participants. More interestingly, the three-way interaction suggested that perceived similarities moderated the link between gender-roles and sexual prejudice among heterosexual men, but not among heterosexual women. Attitude in favor of traditional gender-roles was related to sexual prejudice for male participants who perceived gay men as different, but not for those who perceived gay men as similar. These findings are discussed in terms of the defensive function of men's attitude toward homosexuality as a result of threat to masculinity.     

The relation of perceived situation similarity to perceived behavior similarity: Implications for social learning theory

A number of theories suggest that people behave similarly in similar situations. Social learning theory in particular suggests that people behave similarly in situations perceived to be similar in their pattern of reinforcement contingencies. This study used two measures of perception of behavior similarity and three measures of perception of situation similarity for 20 situations chosen by each of II female subjects as beingss characteristic of her current life. Measures of perceived behavior similarity included paired comparison judgments and analyses of similarity of ratings of behavior probabilities. Measures of perceived situation similarity included paired comparison judgments and analyses of similarity of ratings of outcome or reinforcement contingencies for the specified behaviors, including both internal and external reinforcers. In addition, reliability estimates were obtained on some tasks. Results indicated the following: (1) Generally there was a statistically significant relationship between measures of perceived situation similarity and measures of perceived behavior similarity. The magnitude of the relationship varied considerably from subject to subject. (2) Measures of the same variables did not show better agreement with one another than they did with measures of the different variables, despite evidence of adequate reliability. The data suggested general support for social learning theory but also evidence that factors other than perceived reinforcers in the situation influence how situations are perceived and how people behave in them.     

Relationships among attention, GSR activity, and perceived similarity of self and others

The present study was designed to test the hypothesis that autonomic change is part of the identification process in a non-stressful paradigm Simulated taped interviews were prepared varying the dimensions of amount of work and success in college Emotional expression by the interviewees was kept to a minimum. College subjects responded with a significantly larger number of nonspecific GSRs to a tape identified by them as being more like themselves than to a tape identified as being less like themselves The nonsignificant comparisons of tapes were discussed in terms of the importance of cognitive activity on autonomic responsivity     

A brief delay decreases perceived similarity and improves discrimination

A same-different discrimination between the colors of 2 halves of a circle was poorer when the halves were viewed simultaneously than when the delay between viewing them was 33 ms. The simultaneous discrimination also produced a poor performance on different stimuli relative to same stimuli in comparison to the successive discrimination. Poor-on-different performance should indicate high perceived similarity. The simultaneous colors were also judged as more similar. The delay did not alter the physical similarity of the colors. Thus, the delay may have decreased assimilation (perceived similarity) and thereby improved discrimination, in support of the hypothesis that perceived similarity frequently affects discrimination.     

Learning under your gaze: the mediating role of affective arousal between perceived direct gaze and memory performance

Previous studies have shown that cognitive performance can be affected by the presence of an observer and self-directed gaze. We investigated whether the effect of gaze direction (direct vs. downcast) on verbal memory is mediated by autonomic arousal. Male participants responded with enhanced affective arousal to both male and female storytellers’ direct gaze which, according to a path analysis, was negatively associated with the performance. On the other hand, parallel to this arousal-mediated effect, males’ performance was affected by another process impacting the performance positively and suggested to be related to effort allocation on the task. The effect of this process was observed only when the storyteller was a male. The participants remembered more details from a story told by a male with a direct vs. downcast gaze. The effect of gaze direction on performance was the opposite for female storytellers, which was explained by the arousal-mediated process. Surprisingly, these results were restricted to male participants only and no effects of gaze were observed among female participants. We also investigated whether the participants’ belief of being seen or not (through an electronic window) by the storyteller influenced the memory and arousal, but this manipulation had no effect on the results.     

Effects of perceived similarity on vicarious emotional conditioning

The present experiment tested the hypothesis that perceived similarity between observers and models enhances vicarious emotional conditioning. Subjects were led to believe that they were either similar to the model in beliefs and attitudes, different from him or were given no information about him. They then underwent a vicarious classical conditioning procedure by witnessing the model express pain reactions in conjunction with a neutral stimulus. Observers developed emotional reactions to the neutral stimulus alone after seeing it paired with modeled pain expressions. Preceived similarity, however, had no significant effect on either the level of vicarious conditioning or the rate of extinction. Subjects who had no information concerning the model displayed stronger autonomic responses to the model's pain expressions, and more frequent and intense autonomic responses to the conditioned stimulus during tests for acquisition and extinction. In correlational analyses, subjects in the latter condition also yielded a significant positive relationship between self-reported arousal and vicarious emotional conditioning. The obtained findings were interpreted in terms of the emotion arousing properties of unfamiliarity.     

Seeing structure: Shape skeletons modulate perceived similarity

An intrinsic part of seeing objects is seeing how similar or different they are relative to one another. This experience requires that objects be mentally represented in a common format over which such comparisons can be carried out. What is that representational format? Objects could be compared in terms of their superficial features (e.g., degree of pixel-by-pixel overlap), but a more intriguing possibility is that they are compared on the basis of a deeper structure. One especially promising candidate that has enjoyed success in the computer vision literature is the shape skeleton—a geometric transformation that represents objects according to their inferred underlying organization. Despite several hints that shape skeletons are computed in human vision, it remains unclear how much they actually matter for subsequent performance. Here, we explore the possibility that shape skeletons help mediate the ability to extract visual similarity. Observers completed a same/different task in which two shapes could vary either in their skeletal structure (without changing superficial features such as size, orientation, and internal angular separation) or in large surface-level ways (without changing overall skeletal organization). Discrimination was better for skeletally dissimilar shapes: observers had difficulty appreciating even surprisingly large differences when those differences did not reorganize the underlying skeletons. This pattern also generalized beyond line drawings to 3-D volumes whose skeletons were less readily inferable from the shapes’ visible contours. These results show how shape skeletons may influence the perception of similarity—and more generally, how they have important consequences for downstream visual processing.

     

Depression and interpersonal attraction: the role of perceived similarity

We hypothesized that depressed individuals are generally viewed as dissimilar and that this perceived dissimilarity contributes to negative reactions to the depressed. In addition, we hypothesized that if perceived similarity affects liking of depressed individuals, then nondepressed subjects should prefer nondepressed targets, but depressed subjects should not share this preference. To test these hypotheses, depressed and nondepressed subjects received information about two targets, both either depressed or nondepressed, one attitudinally dissimilar and one attitudinally similar. They were then asked to fill out an attraction measure and an interest in meeting measure for each target. The results clearly supported the primary hypotheses, demonstrating that nondepressed subjects preferred nondepressed targets and perceived them as more similar than depressed targets, and that this preference for nondepressed targets is not shared by depressed subjects. Tests of supplementary hypotheses also confirmed that depressed subjects perceive their best friends as being more depressed and more dissimilar than do nondepressed subjects. The implications of these findings for the social world of the depressed were discussed.     

The role of interdependence and perceived similarity in depressed affect contagion

This study hypothesized that perceived similarity significantly impacts depressed affect contagion only for individuals with highly interdependent self-construals. Baseline self-construal and affect were measured. Then, after reading a vignette about a depressed or nondepressed target, affect and perceived similarity were assessed. Participants reading the depressed vignette reported higher negative affect than participants reading the nondepressed vignette. Positive affect did not differ between the two conditions. For participants exposed to the depressed vignette, the hypothesized interaction between perceived similarity and interdependence significantly predicted positive affect. It appears that participants with more interdependent self-construals were more likely to "catch" the low positive affect displayed by the depressed target only if they perceived themselves as highly similar to the target.
