Previous research indicates that individuals employ various cognitive heuristics and decision modes in making decisions and judgmental tasks that do not follow an expected value model. It further indicates that several cognitive faculties are affected by stress. The purpose of this study was twofold: first, to examine whether individual differences exist in the use of cognitive heuristics and risk-assessment decision modes; second, to examine whether stress would affect the use of these cognitive strategies. Three versions of a questionnaire measuring the representativeness and availability heuristics, and risk-seeking and risk-aversion decision modes were administered to three different groups of subjects. Consistent individual differences were only observed in the subscales measuring risk-seeking and risk-aversion modes, but not in the use of the heuristics. In a different group of subjects, exposure to noise and task overload stress increased the use of the representativeness heuristic, but did not alter the use of risk-seeking and risk-aversion decision modes. These results indicate that the existence of individual differences in cognitive strategies may determine, in part, whether stress will modify judgmental processes.  相似文献

Pastors' children have been thought to have more behavioral problems than other children since they face high expectations and are part of families that are often under public scrutiny. The purpose of this study was to describe the social competencies and behavioral problems of a national sample of pastors' children, aged 4–16, and to compare them to age and sex standardized norms. Data were obtained on 98 children from a random sample of 62 families, using the Child Behavior Checklist. Results indicate that scores for both boys and girls at each age grouping fell within the acceptable norms for both social competencies and behavioral problems.  相似文献

While advertising products with reflections is a common industry practice, this research is the first to investigate their impact on product aesthetics. Reflections are endowed with an inherent shine since they are naturally formed by the interaction of light with an object and a reflecting surface. We draw upon this property along with Evolutionary Psychology (EP) research documenting an intrinsic human attraction towards gloss to predict their positive effect on product aesthetics. Further in line with the EP principles, we propose that this effect is mediated by enhanced pristineness perceptions about the product in the presence of its reflection in the ad. Finally, we draw upon the Elaboration Likelihood Model (ELM) to identify product design complexity as a boundary condition for the positive effect of reflection on product attractiveness perceptions. For a product with relatively high (vs. low) design complexity, with design being the focal aspect that is elaborated via a central route, we predict the effect of a peripheral stylistic cue like product reflection to attenuate. Three experimentally designed studies employing different product types offer empirical support to these predictions. Our work extends prior marketing research studying the effects of executional elements in advertising on consumers' product reactions, particularly the aesthetic impact of product reflections as creative stylistic cues. The managerial implications of this work span both traditional and digital marketing channels. Incorporating a product reflection in advertising can work as an easy-to-implement option that can help practitioners elevate product pristineness and aesthetics. On the other hand, avoiding their use when advertising products with relatively complex designs can save both ad space and money.  相似文献

This paper endeavors to find an optimal solution to alleviate the harmful consequences of choice overload using assortment categorization. Past research on assortment categorization has primarily studied the type of category labels. Only a few studies focused on the number of category labels, and the extant research is inconclusive on the right number of labels. This paper argues that the number of options under each label is more important in reducing choice overload than the number of labels. We call the number of options under each label “category ratio”. We integrate the research from four streams to recommend an optimal range of category ratio. In a field and a lab experiment, we tested the optimal category ratio as an intervention in the reduction of choice overload. The results of both experiments found a significant reduction in choice overload for the optimal category ratio. In experiment 3, we manipulated the category ratio to test whether the optimal category ratio is better than the non-optimal category ratio. The results of experiment 3 found that consumers experienced more satisfaction for the optimal category ratio than both uncategorized assortment and non-optimal category ratio. Past research has found that fewer labels and uninformative categorization are not helpful in the choice process. This paper finds that a few labels are beneficial only when the category ratio is within the proposed optimal range. Uninformative labels also reduced choice overload when categorized using the optimal category ratio.  相似文献

The direct methods of ratio estimation and magnitude estimation and the indirect method of pair comparison were used to construct scales of liberalism and conservatism. It was found ( a ) that the scales of conservatism are linearly related to each other and ( b ) those of liberalism are also linearly related to each other but with a discontinuity in the middle of the range; one linear function for the conservative statements and another for the liberal statements, with the discontinuity occurring in the middle of the subjective scale. Liberalism vs. conservatism was found to be reverse. The linear function between all kinds of scales as well as the reverse relation between liberalism vs. conservatism suggest that the continuum of political preferences is metathetic.  相似文献

The belief that men are taller than women is an accurate gender stereotype that is presumably learned through everyday encounters with men and women. It is unlike most gender beliefs that are difficult to quantify and verify, and that may be learned through means other than direct experience. This research makes use of several advantages available when studying an accurate stereotype (e.g., the ability to know the “truth” about judged targets). Subjects from five different age/grade levels (kindergarten, third grade, seventh grade, tenth grade, and college, N=491, 92.26% Caucasian, 7.54% Arabic, 0.2% African American) made judgments of “who is taller” among photographed male—female pairs that had actually been matched in height. Judgments were made of kindergarten, seventh grade, and college photo pairs. In a developmental context, height judgments are particularly interesting because the gender difference in height changes at different ages—specifically, girls are taller than boys around seventh grade. The data indicated that subjects were sensitive to the changing height stereotype—i.e., they judged adult males taller than adult females, but seventh grade females taller than seventh-grade males. However this was most strikingly true among subjects directly faced with this reality in their peer context—seventh graders—and among college students. Height judgments were also sensitive to an ingroup (gender) bias. The data are discussed in reference to the broader literature on stereotyping and base rate influences on judgment.  相似文献

In two studies, subjects' stereotypes of various campus groups were assessed using a content-free, cognitive methodology in which stereotypes are defined as "generalizations about a class of people that distinguish that class from others" (McCauley, Stitt, & Segal, 1980, p. 197). In an effort to predict strength of stereotypes, four main findings emerged: (a) contact with a group's members was associated with increased liking of the group; (b) contact predicted increased stereotype strength; (c) liking a group was associated with decreased stereotype strength; and (d) over time, the strength of stereotypes tended to decrease. These data are discussed in regard to the contact hypothesis (Airport, 1954; Amir, 1969; Cook, 1978,1984), the role of positive affect in altering cognitive organization, and more generally, to the issue of stereotype development.  相似文献

The essay examines the argument advanced by E.D. Hirsch, Jr., for instituting ‘cultural literacy’ as a fundamental priority of schools. A number of confusions and equivocations in Hirsch's reasoning are identified, and the propensity of his project to indoctrinate is exposed. Among the features of Hirsch's argument shown to be troubling are his shifting construal of ‘language’, his inconsistency about the requirements of cultural literacy, and his uncritical relation to traditional images of the American past and present. The upshot is to raise the question why Hirsch's project has elicited wide support and praise.  相似文献

Self-reported parental stress was investigated in three samples of mothers with small children, using a Swedish version of the Parenting Stress Index (PSI). Dimensionality in experienced stress using items from six PSI Parent Domain subscales and eight new items was examined in factor analyses of data from a nationwide representative sample. Cross-validation proved the chosen factor pattern to be stable. Based on an oblique 5-factor solution new subscales were constructed. A second order factor analysis indicated influence from a higher order factor, seen as a general parental stress construct. High alpha coefficients revealed that homogeneous subscales had been formed. Test-retest correlations indicated good stability over a mean time period of 30 days. Influences from maternal background variables were found, but no relation to child age or gender. Global estimates of parental stress, reported child problems, mothers' scoring on the Edinburgh Postnatal Depression Scale and two measures of social support all correlated significantly with overall parental stress, and with some subscales. The justification of the subscale approach to parental stress was discussed. It was concluded that the PSI in its present form could be used as a reliable and valid instrument for measuring experienced parental stress in mothers of young children.  相似文献
