Two contradictory hypotheses regarding the effect of self-attention or self-awareness on task performance are considered. Recent research on test anxiety indicates that self-awareness interferes with task performance by decreasing the proportion of attention paid to the task. Wicklund and Duval's (1971) theory of objective self-awareness predicts the opposite: that self-awareness will induce a person to try harder and to perform at a higher level. Experimental evidence indicates that both hypotheses are correct, each at a different level of evaluation. The results are discussed in terms of their implications for a unified social-psychological theory of evaluative self-awareness which could account for findings now classed under separate headings such as test anxiety, self-awareness, and social facilitation.  相似文献

Two kinds of explanations have been offered for the process by which three-term series problems are solved, one in terms of linguistic principles and the other in terms of visual-spatial imagery. Two experiments are reported in which three different classes of operations are brought to bear on the problem: (1) Manipulation of stimulus attributes (characteristics of problems), (2) manipulation of variables that selectively encourage or inhibit the use of imagery (facilitating instructions; the suppression of visualization by reading), and (3) measurement of relevant individual differences (spatial-reasoning ability). All of the results indicate that imagery plays a functional but not a necessary role in the solution of three-term series problems; it is suggested that imaginal representation is functional because it reduces the load on memory. An adequate explanation of problem-solving will have to address certain general issues, such as the diversity of forms of cognitive representation and differences within and between individuals in the choice of problem-solving strategies.  相似文献

According to the theory of objective self-awareness (Duval & Wicklund, 1972), the concept of generalized drive is unnecessary, its explanatory function having been replaced by the concepts of self-evaluation and desire to be “correct”. An experiment was designed to compare alternative predictions from the drive and self-awarencess theories. Subjects listened to music in the presence of a mirror and, at another time, not in the presence of a mirror. The effect of self-consciousness on several habitual behaviors related to smoking was assessed. It was known that the subjects believed the number of cigarettes one should smoke “ideally” was significantly less than the number they actually smoked. Hence, the theory of objective self-awarencess predicts decreased smoking in the presence of the mirror, while a drive theory interpretation of self-consciousness predicts the opposite. Results generally supported the drive theory.  相似文献

By a Thurstone Case III representation for binary symmetric choice probabilities Px,y we mean that there exist functions F, μ, σ > 0 such that Px,y = F[(μ(x) ? μ(y))2(x) + σ2(y))12]. We show that the constraint σ = constant, or μ = ασ + β, α ≠ 0, is both necessary and sufficient for a Thurstone Case III representation to be Fechnerian, i.e., to be reexpressable as as Px,y = G(u(x) ? u(y)) for some suitably chosen functions G, u.  相似文献

Female right-handed subjects were presented with a memory set consisting of five unfamiliar female voices. They were then tested with a recognition procedure in which samples of voice, memory set or novel, 2 or 4 sec in duration, were heard in one ear and a competing noise stimulus was heard in the other ear. There was an overall left-ear advantage in accuracy of recognition. This advantage held particularly for identifications of memory-set voices in the second half of trials. Internal analyses indicated that the left-ear advantage could not be attributed to greater retroactive interference during right-ear presentation. Congruent with studies of recognition of unfamiliar faces, the findings suggested right-hemisphere superiority in the recognition of unfamiliar voices.  相似文献

When faced with the task of making a prediction or estimating a likelihood, it is argued that people often reason about the presence or absence and relative strength of possible causal mechanisms for the production of relevant outcomes. In so doing people rely on “causal cues” or properties of an inferential problem which indicate the nature of the particular causal processes which give rise to specific outcomes. It is hypothesized that causal cues, precisely because they focus attention and thought on specific causal mechanisms, can obscure the relevance of mathematical laws of probability and lead to statistically biased judgment. Two experiments were conducted. Their results support the hypothesis, showing that the incidence of the conjunction fallacy and the base rate fallacy depend on task-specific cues for causal reasoning.  相似文献

The majority of theories about the effects of schemata (or generic knowledge structures) on information processing share two fundamental assumptions. It is assumed, first, that schema-based inferences about unobserved features of an event are generated, and, second, that such inferences are stored in long-term memory and thereby confused with traces of observed features of that event. To test these assumptions, researchers rely heavily on recognition memory measures of hit and false alarm rates. In the present paper, it is observed that schema theoretic interpretations of recognition memory measures are inconsistent with an interpretation jointly derived from the theory of signal detection and Mandler's (1980, Psychological Review, 87, 252–271) subjective familiarity theory of recognition memory; from the latter's perspective, recognition memory measures are considerably more ambiguous than schema researchers realize and do not necessarily support the typical schema theoretic interpretations. Data from four experiments are analyzed from the perspective of the theory of signal detection/ subjective familiarity model and demonstrate the ambiguity of recognition memory measures for testing hypotheses about the function and consequences of schemata for information processing.  相似文献

Prompted by a concern with the effects of appearance on how individuals and their work are regarded and how rewards are allocated in work settings, an experiment was conducted to determine whether physical attractiveness differentially affects the performance evaluations and recommended personnel actions for men and women holding managerial and nonmanagerial jobs. As predicted, attractiveness proved to be advantageous for women in nonmanagerial positions and disadvantageous for women in managerial ones. Unexpectedly, however, appearance had no effects whatsoever on reactions to men. Additional results indicated that attractiveness enhanced the perceived femininity of our female stimulus people, but did not enhance the perceived masculinity of those who were male. These data were interpreted as supportive of the idea that the differential effects of appearance in work settings are mediated by gender characterizations, and that fluctuations in the perceived person-job fit are key to understanding the seemingly inconsistent reactions to attractive and unattractive women in employment situations. The theoretical and applied implications of these findings are discussed.  相似文献

In two experiments, 5-, 7-, 9-, and 11-year-old children and college students were presented on each trial with a sentence followed by a probe word. Their task was to indicate whether the probe was in the sentence or not. Of primary interest were the false recognitions and the correct latencies that occurred when the probe word was a synonym or antonym of one of the words in the sentence (Experiment I) or when the probe was a subordinate, superordinate, part, or whole (Experiment II). The younger children were more affected by synonymy than antonymy, although the older children and adults were not. At all ages, the categorical relationships caused more recognition confusion than the partwhole relationships. Subjects were more affected when the probe was a superordinate than when it was a subordinate, and somewhat more affected when the probe was the whole than when it was the part. These results suggest that children as young as 5 years of age have well-organized conceptual systems based on shared meaning components.  相似文献

In three experiments, deaf children in the age range of 6 years, 10 months to 15 years, 5 months were presented with continuous lists of items, and for each item they had to indicate whether it had appeared before on the list. Later items were related to preceding items either in surface form or in meaning or were unrelated. False-recognition errors (i.e., “yes” responses to new items) served as an index of memorial coding. In one experiment, the items presented to the subjects were printed words. The results of this experiment showed a false-recognition effect (i.e., more errors to related words than to unrelated words) for both semantically related words and orthographically similar words. In the other two experiments, the subjects viewed a series of manual signs on videotape. In these experiments, there was a false-recognition effect for signs related semantically and for signs related cherologically (i.e., similar in terms of their manual production). These results establish orthography and cherology as effective memorial codes for deaf children. The finding of a consistently strong semantic effect for young deaf children stands in contrast to findings of weak semantic effects in false-recognition studies with young hearing children. The ascendancy of semantic codes for deaf children was attributed to the absence of competition from the speech code which dominates the linguistic memory of hearing children.  相似文献

It has been suggested that asymmetries in the morphological properties of the face contribute to or produce asymmetries in facial emotional expression. Over 50 years of research on hard tissue, soft tissue, and facial surface asymmetries is reviewed here. Generally, it appears that if consistent asymmetry characterizes facial morphology, it is extremely small in magnitude or characterizes regions yet to be examined. In contrast, marked homology and asymmetry in regional size and area has been noted often. At present, it does not appear that asymmetry in facial morphology is associated with facial expressive asymmetry, with the latter more likely to be an outcome of functional brain asymmetry.  相似文献

This paper discusses a sufficient set of conditions for a structure to be ordered-ring isomorphic to a positive subinterval of the real numbers. It extends our previous results concerning bounded versions of Hölder's Theorem (Falmagne, 1971). The main result can serve as a basic lemma for establishing representation theorems in polynomial conjoint measurement when the empirical sets contain neither large elements nor ones close to the natural zero.  相似文献

On the development of color naming in young children: data and theory   总被引:2,自引:0,他引:2  
Among the semantics of different common attributes of the environment, consistent and correct color naming seems to develop paradoxically late in children, for even young infants discriminate and categorize colors well, color is a salient feature of the child's world, and children are aware of color as a separate domain, know color terms, and respond to color questions with color names. Several specific anomalies characterize early linguistic development in this domain: Errors in beginning color naming are perseverative or random, there seems to be a minimum age for correct and consistent color naming, developmental rate shows wide individual differences, and acquisition among girls is generally faster than among boys. This essay reviews data that support these observations, and evaluates three traditional explanations for them--including the perceptual salience of color for children, experience and learning in the child, and cognitive development--against a fourth new possibility. It is hypothesized that appropriate color naming may depend on the maturation and integration of specific cortical neurological structures; among several interpretations, the neurological one accounts best for diverse characteristics of early color naming.  相似文献

A cross-sectional comparison of school children in grades 6, 9, 10, and 12 and their parents was made to examine changes in work values and the relationship between children's and their parents' work values as a function of age and sex. Discriminant function analyses revealed support for hypothesized differences in children's values and for the convergence of sex differences in values at later ages. Results also confirmed that at earlier ages there is greater similarity in values between children and their like-sexed parent but older (grade 12) boys and girls are most similar to their fathers. These findings confirm and expand the results of earlier research.  相似文献

In this study, the effects of performance-contingent rewards on intrinsic motivation were examined in comparison to no-reward controls receiving identical performance feedback. A path analytic process analysis was conducted to examine the mediation of reward effects on subsequent task interest. It was hypothesized that competence valuation, or the personal importance of doing well, would be an important mediator of interest in situations where performance feedback was available. Rewards were predicted to affect interest by influencing an individual's valuation of competence, and by altering the competence valuation mediation process. In addition, achievement orientation was hypothesized to interact with reward in affecting importance and the mediation process. Prior to performing an interesting puzzle, high school students were offered a performance-contingent reward, and then indicated how personally important it was to do well. After doing three puzzles, all subjects received positive feedback regarding their performance. Multiple regression analyses indicated that importance was affected by the experimental variables, and had a positive causal impact on subsequent intrinsic motivation. It was found that the promise of performance-contingent reward positively affected importance for low achievers relative to high achievers, and that the mediation of subsequent intrinsic interest by importance differed according to reward by achievement combinations. Additionally, a direct effect revealed that performance-contingent rewards significantly enhanced interest, relative to no-reward controls receiving identical performance feedback.  相似文献

The purpose of this study was to clarify the meaning of the construct, career orientation. Fourteen presumed measures of career orientation as well as Super's Work Values Inventory were administered to college women. Analysis of the relationships among these variables identified two relatively independent clusters. The first cluster most closely approximated the usual definition of career orientation. Career-oriented women were found to be highly career motivated and perceived the career role as primary in their adult lives. The second cluster was called work orientation. This orientation characterized women with well-defined occupational aspirations who placed a high value on both the career role and marriage-family responsibilities in their future. Work-oriented women tended to choose traditionally feminine occupations in contrast to the career-oriented women whose aspirations included higher level and less traditional occupations.  相似文献
