The authors examine how political ideology impacts consumer preferences for hedonic and utilitarian choices and the underlying reasons for these differences. Five studies indicate that conservatives are less tolerant of ambiguity than liberals, leading to a preference for utilitarian options, whereas liberals are more tolerant of ambiguity leading to a preference for hedonic options. However, these preferences were reversed when utilitarian options were framed as ambiguous and hedonic options were framed as explicit and clear.  相似文献

The primary goal of this study was to examine the relations between limb control and handedness in adults. Participants were categorized as left or right handed for analyses using the Edinburgh Handedness Inventory. Three-dimensional recordings were made of each arm on two reach-to-place tasks: adults reached to a ball and placed it into the opening of a toy (fitting task), or reached to a Cheerio inside a cup, which they placed on a designated mark after each trial (cup task). We hypothesized that limb control and handedness were related, and we predicted that we would observe side differences favoring the dominant limb based on the dynamic dominance hypothesis of motor lateralization. Specifically, we predicted that the dominant limb would be straighter and smoother on both tasks compared with the nondominant limb (i.e., right arm in right-handers and left arm in left-handers). Our results only partially supported these predictions for right-handers, but not for left-handers. When differences between hands were observed, the right hand was favored regardless of handedness group. Our findings suggest that left-handers are not reversed right-handers when compared on interlimb kinematics for reach-to-place tasks, and reaffirm that task selection is critical when evaluating manual asymmetries.  相似文献

Some marketers use game settings to offer deals. Though research has studied the conditions under which consumers engage in such games, we know little about how they respond to deal offers won through the gaming process. We hypothesize that when faced with deal offers from games, such as scratch cards or trivia quizzes, consumers who are high (vs. low) in choice freedom needs often feel reactance and reject the offer. We find converging evidence for this prediction in both controlled experiments (studies 1 and 3) and in a field study (study 2), when using ethnic backgrounds as a proxy for participants’ choice freedom needs (study 1), when directly measuring these needs (study 2), and when manipulating beliefs about the importance of free choice (study 3).  相似文献

Current research on the nature of attentional deficits in attention-deficit hyperactivity disorder (ADHD) is reviewed with a focus on studies using event-related potentials (ERPs). A robust effect is the smaller amplitude of the P3 wave to both auditory and visual stimuli for individuals with ADHD than for normal controls. This effect is indicative of deficits in the allocation of attentional resources to task-relevant information. The Nd wave is also smaller for individuals with ADHD, an effect that suggests impairments in the discrimination and preferential processing of task-relevant information, rather than distractibility by irrelevant stimuli. Studies of the effects of methylphenidate on ERPs in ADHD indicate that this stimulant enhances the quality of stimulus evaluation and speeds response time. These specific effects support the view that ADHD involves deficits in energetic processes that are required for processing task-relevant stimuli.  相似文献

The present study investigates the role of dispositional need for closure (NFC) in how individuals within a particular culture perceive and appreciate choice. Data sets from the US (283 adults), Europe (263 adults and 427 students), China (218 adults and 309 students) and Singapore (258 students) were collected. The results showed that in Western cultures, people perceived choice in a linear way as either a burden or a blessing, whereas in Chinese culture, such opposition between perspectives did not appear, and individuals generally saw choice as both burden and blessing simultaneously. In Western cultures, high dispositional NFC was strongly associated with viewing choice‐as‐a‐burden, whereas Chinese respondents with a high NFC perceived choice as a blessing and a burden simultaneously. The Singaporean results were similar to the Western pattern. These findings are discussed in terms of the NFC literature and cultural differences in dialectic versus differentiation thinking styles.  相似文献

The “exchange paradox”—also referred to in the literature by a variety of other names, notably the “two-envelopes problem”—is notoriously difficult, and experts are not all agreed as to its resolution. Some of the various expressions of the problem are open to more than one interpretation; some are stated in such a way that assumptions are required in order to fill in missing information that is essential to any resolution. In three experiments several versions of the problem were used, in each of which the information given was sufficient to determine an optimal choice strategy when it exists or to justify indifference regarding keeping or trading when such a strategy does not exist. College students who were presented with the various versions of the problem tended to base their choices on simple heuristics and to give little evidence of understanding the probabilistic implications of the differences in the problem statements.  相似文献

Our target article proposed an alternative perspective for studying consumer judgment and decision making, focusing on the types and weights of comparisons consumers select. In this response we consider the major points made by each of the commentators and examine their implications for future work addressing our comparison-focused approach.  相似文献

This paper reviews progress over the past 20 years in four areas of research on infant perception and cognition. Work on perception of dynamic events has identified perceptual constraints on perception of object unity and object trajectory continuity that have led to a perceptual account of early development that supplements Nativist accounts. Work on face processing has charted developmental changes that clarify the way innate systems are modified by experience. Research on perception of goal‐directed action and animacy has made significant progress in uncovering the roots of social cognition from 6 months onwards. New methods such as eye tracking and measures of brain activity have done much to confirm and clarify conclusions arising from more conventional looking preference methods. It is likely that future progress in theory and understanding will be made increasingly as a result of triangulation between data arising from conventional and newer methods.

A 2‐year longitudinal study of 33 children aged 4–6 years was conducted to clarify the developmental relationship between calculation skill and finger dexterity, as well as the selectivity of the predictive power of finger dexterity on later calculation skill. We examined individual developmental change in the relationship between addition performance and finger dexterity and observed whether children fit a linear developmental pattern. Multiple regression analysis showed that participants' performance on addition tests was strongly predicted by their finger dexterity. However, their performance on vocabulary tests was not strongly influenced by finger dexterity. These findings suggest that calculation skill in children aged 4–6 years is strongly related to finger dexterity.  相似文献
