Pseudocontingencies in Consumer Choice: Preference for Prevalent Product Categories Decreases with Decreasing Set Quality 下载免费PDF全文
Building on theorizing about contingency inferences, the present research deals with the impact of product category prevalence on consumer choice. We argue that a category's prevalence in the choice set can signal high quality, but the validity depends on the aggregate quality of the choice set. With ever more low‐quality products in the set, high prevalence should increasingly signal poor rather than high quality. When choosing from a poor‐quality set, choices should thus favor products from the rare category. In four experiments, we show that poor‐quality sets increase the proportion of consumers choosing products from a rare category. Furthermore, we show that these effects increase when base rates of a category and quality become more extreme. Finally, Experiment 4 shows that contingency inferences partly mediate the effect of set quality on choice. The results extend previous research on contingency inferences, indicating the adaptive use of base‐rate information in consumer decision making. Copyright © 2017 John Wiley & Sons, Ltd. 相似文献

In this study hemispheric asymmetries for categorizing objects at the basic versus subordinate level of abstraction were investigated. As predictions derived from different theoretical approaches are contradictory and experimental evidence is inconclusive in this regard, we conducted two categorization experiments, where we contrasted two experimental paradigms. In the first experiment, subjects had to verify whether a word and a laterally presented picture matched or not. In the second experiment, subjects had to identify laterally presented pictures of animals either at the basic or subordinate level by pressing a corresponding response key. Whereas the first experiment revealed an advantage of the left hemisphere (LH) for categorizing objects at the basic level and of the right hemisphere (RH) for categorizing at the subordinate level, just the opposite brain asymmetry was found in the second experiment. As the stimuli were identical in both experiments, hemispheric asymmetries seem to be strongly task dependent. 相似文献

Previous research (Greitemeyer & Weiner, 2003 ) has demonstrated that compliance, because of an anticipated reward is attributed more to the person than compliance because of an anticipated punishment. The present research extended these findings to an educational context. Three studies revealed that parents who ask their children to change inappropriate behaviors are more likely to ascribe their children's improvement to the child, if the child was promised a reward, rather than threatened, to receive a punishment if the child did not improve. Moreover, because a child's improved behavior is more likely to be ascribed to the child given a reward as compared to a punishment, parents expect that rewards (as opposed to punishments) are more likely to sustain improved behavior, when the incentive is no longer offered. Finally, participants report to be more likely to induce behavioral change through reward rather than punishment. Copyright © 2007 John Wiley & Sons, Ltd. 相似文献

The nature of episodic associations has been subject to a long standing debate, where the two opposing positions postulate associations as either a holistic representation of the constituent elements or as independently modifiable pointers between them. In spite of a history of inconsistent findings, evidence in favour of the theory of symmetric associations has accumulated, yet only for verbal memory [Caplan, J. B., Glaholt, M. G., & McIntosh, A. R. (2006). Linking associative and serial list memory: Pairs versus triples. Journal of Experimental Psychology: Learning, Memory, and Cognition, 32(6), 1244-1265; Kahana, M. J. (2002). Associative symmetry and memory theory. Memory and Cognition, 30(6), 823-840]. Although object-location associations differ in several fundamental characteristics from verbal paired-associates, we recently found associative symmetry in the memory for this class of associations as well [Sommer, T., Rose, M., & Büchel, C. (2007). Associative symmetry vs. independent associations in the memory for object-location associations. Journal of Experimental Psychology: Learning, Memory, and Cognition, 33(1), 90-106]. Due to the inconsistencies in the verbal literature, we felt it to be pertinent to confirm this finding using another experimental approach. Based on recent advances in understanding the effects of successive testing, we were able to make use of this knowledge and introduce this effect as an experimental manipulation in the study of associative symmetry. In particular, we investigated whether the influence of a prior memory test on a subsequent memory test differs when the same or opposite constituent element of an object-location paired-associate cues the retrieval on each test. We observed an identical testing effect for both conditions, which was exclusively driven by reminiscence, the recovery of previously inaccessible information. This finding lends strong support in favour of holistically or symmetrically represented object-location associations and suggests, given the verbal memory literature, a general principle of associative symmetry [Asch, S. E., & Ebenholtz, S. M. (1962). The principle of associative symmetry. Proceedings of the American Philosophical Society, 106, 135-163]. 相似文献

The authors found that 3 experiments revealed that compliance with a pro-social request for an anticipated reward as opposed to a threatened punishment resulted in greater inferences of personal morality. In Experiment 1, participants received information about a teaching assistant (TA) who was either promised a reward or threatened with a punishment when asked for compliance. The participants perceived the TA as more moral for complying given the positive incentive as opposed to the negative incentive. Experiment 2 replicated this finding in a different culture, using different vignettes and incentives. Last, in Experiment 3, the results revealed that a perceived actor's real intentions mediated the effect of incentive valence on dispositional causation. That is, given a reward relative to a punishment, participants were more likely to assume that the agent would have helped even if no incentive had been offered. 相似文献

This paper argues that ‘that’-clauses are not singular terms (without denying that their semantical values are propositions).
In its first part, three arguments are presented to support the thesis, two of which are defended against recent criticism.
The two good arguments are based on the observation that substitution of ‘the proposition that p’ for ‘that p’ may result
in ungrammaticality. The second part of the paper is devoted to a refutation of the main argument for the claim that ‘that’-clauses
are singular terms, namely that this claim is needed in order to account for the possibility of quantification into ‘that’-clause
position. It is shown that not all quantification in natural languages is quantification into the position of singular terms,
but that there is also so-called ‘non-nominal quantification’. A formal analysis of non-nominal quantification is given, and
it is argued that quantification into ‘that’-clause position can be treated as another kind non-nominal quantification. 相似文献

Epidemiological studies have shown that chronic work stress or unfavourable psychosocial work conditions are prospectively associated with different adverse health outcomes. The aim of the present cross-sectional study was to investigate the relationship between work-related chronic stress as well as exhaustion and a cumulative measure of physiological wear-and-tear called allostastic load (AL). AL could be a possible biological pathway for how chronic work stress and exhaustion lead to health impairments in the long run. As the teaching profession has been proposed to be a potentially high stressful occupation, chronic work stress (effort-reward-imbalance) and exhaustion were assessed in 104 female school teachers. AL was first analyzed according to McEwen's classical model comprised of ten parameters including cortisol, epinephrine and norepinephrine, dehydroepiandrosterone-sulphate (DHEA-S), waist/hip-ratio (WHR), glycosylated haemoglobin (HbA1c), high-density lipoprotein (HDL), total cholesterol/HDL-ratio, and systolic and diastolic blood pressure. Additionally it was extended to include tumor-necrosis-factor-alpha (TNF-alpha), C-reactive protein (CRP), fibrinogen, D-dimer, percent-body-fat, triglycerides, and glucose levels. A substantial proportion of our sample was highly exhausted whereas relatively few teachers showed high effort-reward-imbalance. AL scores were significantly higher in women high on effort-reward-imbalance or suffering from exhaustion. Although all teachers had been in a good health status, chronic work stress as well as exhaustion appears to be associated with changes in a multi-system summary indicator of physiological risk. 相似文献
