Reducing fears and increasing assertiveness: The role of dissonance reduction

In the research paradigm known as effort justification, people engage in an effortful activity in order to attain a goal. As a result, the goal becomes more attractive. Two experiments were conducted to test the notion that the effort justification sequence can account for the positive changes that result from psychotherapy. In the first experiment, subjects who were afraid to approach a snake underwent one of two types of effortful therapy. One was a modified form of an anxiety-producing therapy known as “implosive therapy”; the other was merely a set of physical exercises. It was reasoned, on the basis of cognitive dissonance theory, that the expenditure of effort would lead to a positive change in the ability to approach the snake but only under conditions of high decision freedom. Half of the subjects in each of the therapy conditions participated with high choice; the other half with low choice. Subjects' improvement in their approach to snakes was assessed. A main effect for decision freedom was predicted and found independently of the type of effort that subjects expended. A second experiment conceptually replicated the findings of the first experiment. Subjects who wanted to become more assertive participated in an effortful, physical exercise therapy or in a modified form of the standard treatment for fear of assertiveness. The results of the 2 × 2 factorial experiment again showed a main effect for decision freedom such that high choice subjects became more assertive. The findings were discussed in terms of dissonance and attribution theories as well as for implications for future consideration of psychotherapy.     

Retardation of autoshaping following pretraining with unpredictable food: Effects of changing the context between pretraining and testing

In Experiment 1, pigeons exposed to US ONLY pretraining were observed to be retarded in the acquisition of autoshaping relative to naive controls; however, gross changes in contextual stimuli between pretraining and testing alleviated the retardation effect. In Experiment 2, groups of pigeons exposed to CS ONLY, US ONLY, or random CS-US presentations (TRC) were tested for the acquisition of autoshaping. The US ONLY and TRC groups were retarded relative to naive controls. The context change manipulation eliminated the US ONLY retardation effect and attenuated, but did not eliminate, the TRC retardation effect. Context blocking accounts for the US ONLY effect and contributes to the TRC effect; however, context-independent retardation following TRC pretraining suggests the operation of the learned irrelevance cognition.     

Cognitive dissonance and psychotherapy: The role of effort justification in inducing weight loss

The role of effort justification in psychotherapy was examined. It was hypothesized that the effort involved in therapy, plus the conscious decision to undergo that effort, leads to positive therapeutic changes through the reduction of cognitive dissonance. An experiment was conducted in which overweight subjects attempted to lose weight through one of two forms of “effort therapy”. These therapies were bogus in that they were based solely on the expenditure of effort on a series of cognitive tasks that were unrelated to any existing techniques or theory addressing weight loss. One of the therapies called for a high degree of effort while the degree of effort in the second therapy was low. A no-treatment control group was also included. It was predicted that greater weight loss would occur for high-effort than low-effort or control subjects, and that this weight loss would be maintained or increased over time. Results supported these predictions. Over an initial 3-week period, high-effort subjects lost slightly more weight than low-effort subjects or controls. A 6-month follow-up revealed that the effects of effort on weight loss had increased and were highly significant. Reliable differences remained even 1 year after the initial experimental sessions. Possible mechanisms mediating the dissonance effect were discussed, as were several alternative explanations.     

Children's selective attention with variation in amount of stimulus exposure

Selective attention in children was measured by means of a central-incidental learning paradigm. Children performed a central task requiring attention to one element in each of several stimuli, after which their incidental learning was assessed by a combination of two tests measuring: (a) recognition of the second, or incidental, element in each stimulus, and (b) association between the incidental and central elements. Principal independent variables were the age of the children (9 vs 12 years) and the amount of exposure time per trial in the central task (6 vs 12 sec). Douling the exposure time increased the incidental as well as the central scores for 9-year-olds, while it increased only the central scores for 12-year-olds. It would appear that younger children maintain a relatively nonselective orientation during an extended exposure period, distributing attention between both relevant and irrelevant stimulus elements, whereas adolescents adopt a more selective approach and concentrate exclusively on task-relevant information. The results are discussed in relation to hypotheses regarding development of selective attention.     

Selective self-disclosure with and without correspondent performance

If people are motivated to elicit attributions from others, are they capable of using attribution theory as a means to this end? To explore this question, subjects were asked to select information to disclose to hypothetical target persons in order to have those target persons make specific attributions about the subjects' traits and abilities. The disclosures conformed well to a model sensitive to the principles of augmentation and discounting. The model considers the causal relevance and value of personal information and whether the self-presenter is given the opportunity to engage in behavior that accomplishes some specific self-presentational objective. The results, in line with the model, showed that subjects having the opportunity to engage in such “correspondent” behavior, are subsequently eager to disclose impediments that highlight the likely presence of highly valued behavioral causes. Subjects without such an opportunity seek to disclose facilitating causal factors that would make an effective performance appear to be more likely should the opportunity later arise.     

An interpretation of research of feedback interruption in speech.

The controversial question of the scope of sensory control in the voluntary motor patterns involved in speech is examined by reviewing studies in which the auditory, tactile, and proprioceptive feedback channels have been distorted or interrupted. The author makes a case for open loop control of well-learned speech patterns under normal circumstances. The concept of internal feedback is introduced as a possible control system of skilled speech, whereas response feedback and external feedback are viewed as necessary for children developing speech or adults learning new speech patterns.     

Cognitive and linguistic factors affect visual feature integration

Five experiments investigated the influence of cognitive and linguistic factors on the integration of color and letter-shape information. Subjects were briefly presented strings of colored letters that varied in pronounceability and familiarity. Detection and search tasks required subjects to identify the color of predesignated target letters. It was proposed that errors in integrating color and shape would be less likely with items from different perceptual units than from items within the same perceptual unit. If words, at some level of perceptual analysis, are processed as units whereas nonwords are processed by individual letters, then there should be more letter-shape and color feature integration errors with words than with nonwords. The first two experiments tested this prediction by comparing feature integration errors with words and nonwords. The remaining experiments manipulated letter-string pronounceability, familiarity, and the presence of vowels to isolate the factors that may influence feature integration. The results demonstrate that cognitive and linguistic factors, such as familiarity and pronounceability, can influence the combination of colors and shapes in perception.     

A comparison of the work needs,attitudes, and preferences of professional accountants at different career stages

Although the concept of career stages has played an increasingly important role in vocational psychology, little research exists on career stage differences among professionals. In the present study, a sample of male professional accountants (N = 764) at different career stages were compared with respect to their work needs, work attitudes (intrinsic and extrinsic satisfaction, organizational and professional commitment), and vocational preferences. Accountants at different stages were found to differ significantly in their needs, work attitudes, and the extent to which they fit the Conventional type in Holland's model. In particular, accountants over the age of 60, in the preretirement stage of their career, when compared to their younger counterparts, reported significantly lower levels of job satisfaction but higher levels of organizational and professional commitment, and they demonstrate weaker higher-order needs but stronger security needs.     

The effects of books and gender constancy development on kindergarten children's sex-role attitudes

The effects of symbolic models and level of gender understanding on children's sex-role attitudes was investigated. Kindergarten boys and girls heard and discussed books whose characters depicted either traditional or nontraditional sex-role behaviors. Attitudes toward males and females were measured before and after the picture book treatment. When the study began, children were screened for gender understanding so that half were able to make other-gender constancy judgments, and half were not able to make other-gender constancy judgments. Prior to the treatment, boys and children who had attained gender constancy were slightly negative toward males and neutral toward females, whereas girls and children who had not attained gender constancy were very negative toward males and very positive toward females. Exposure to traditional books had the effect of enhancing attitudes toward males and decreasing attitudes toward females. Exposure to nontraditional books had the opposite effect of decreasing attitudes toward males and enhancing attitudes toward females. The effects of the picture book treatment on attitudes toward females were more pronounced for children who had attained other-gender constancy. Implications for social learning and cognitive-developmental theories of sex-role development are discussed.     

Form and function in early communication: language and pointing gestures

Pointing gestures of verbally advanced 2-year-olds were contrasted with those of less advanced peers, in order to examine the relationships of gesture to language during the acquisition of each. Hypotheses regarding the replacement of gestural functions by speech as verbal skills improve, regarding developmental correspondences between the two communicative domains, and regarding the independence of language acquisition from nonverbal developments were drawn from evolutionary, structuralist, and nativist viewpoints, respectively. Both formal and functional aspects of each communicative skill were measured, and were shown to be largely unrelated, particularly in the gestural domain. No evidence that language replaced gesture for communication in ontogeny was obtained. Correspondences between gesture and language occurred only between functional aspects of each, and the independence of developing language from gestural advances was suggested by the findings.
