Self‐image motives and “sacrosanct beliefs” are powerful motivators of consumer judgment and decision making. The sacrosanct belief that one is rational, for instance, can cause consumers to justify seemingly unwise economic decisions. This article outlines some of the occasions when self‐image motives appear to fail. For instance, although consumers occasionally pat themselves on the back for making questionable purchase decisions, at other times they find fault in perfectly reasonable ones. These and other recent findings provide an exception to the more general rule outlined by Dunning (2007). 相似文献

The roles of serine proteases and protease activated receptors have been extensively studied in coagulation, wound healing, inflammation, and neurodegeneration. More recently, serine proteases have been suggested to influence synaptic plasticity. In this context, we examined the role of protease activated receptor 1 (PAR1), which is activated following proteolytic cleavage by thrombin and plasmin, in emotionally motivated learning. We were particularly interested in PAR1 because its activation enhances the function of NMDA receptors, which are required for some forms of synaptic plasticity. We examined several baseline behavioral measures, including locomotor activity, expression of anxiety-like behavior, motor task acquisition, nociceptive responses, and startle responses in C57Bl/6 mice in which the PAR1 receptor has been genetically deleted. In addition, we evaluated learning and memory in these mice using two memory tasks, passive avoidance and cued fear-conditioning. Whereas locomotion, pain response, startle, and measures of baseline anxiety were largely unaffected by PAR1 removal, PAR1-/- animals showed significant deficits in a passive avoidance task and in cued fear conditioning. These data suggest that PAR1 may play an important role in emotionally motivated learning. 相似文献

The capacity for non-linguistic, numerical discrimination has been well characterized in non-human animals, with recent studies
providing careful controls for non-numerical confounds such as continuous extent, density, and quantity. More poorly understood
are the conditions under which animals use numerical versus non-numerical quantification, and the nature of the relation between
these two systems. Here we test whether cotton-top tamarins and common marmosets can discriminate between two quantities on
the basis of the amount of food rather than on number. In three experiments, we show that when choosing between arrays containing
different numbers and sizes of food objects, both species based their decisions on the amount of food with only minor influences
of numerical information. Further, we find that subjects successfully discriminated between two quantities differing by a
2:3 or greater ratio, which is consistent with the ratio limits found for numerical discrimination with this species. These
studies demonstrate that non-human primates possess mechanisms that enable quantification of total amount, in addition to
the numerical representations demonstrated in previous studies, with both types of quantification subject to similar processing
limits. 相似文献

The persistence of a conditioned flavor preference was examined in 3 experiments. All contained an initial acquisition phase in which half the rats were given almond odor mixed with sucrose (AS) in some sessions and water (W) only in other sessions, whereas the other half (controls) were given explicitly unpaired exposures to almond (A) and sucrose (S) in separate sessions. Subsequent 2-bottle choice tests revealed a persistent preference for A, despite extinction exposure to A or S, but this depended on the choice offered on test: Exposure to A did not extinguish the preference for A over W but did reduce the preference for AS over S; conversely, exposure to S did not extinguish the preference for AS over S but did reduce the preference for A over W. These results indicate that flavor preferences can be resistant to extinction procedures but suggest that the expression of such preferences in choice tests depends on an adaptation-level process. 相似文献

The current study investigated the interpersonal coordination that occurred between two people when sitting side-by-side in rocking chairs. In two experiments participant pairs rocked in chairs that had the same or different natural periods. By instructing pairs to coordinate their movements inphase or antiphase, Experiment 1 investigated whether the stable patterns of intentional interpersonal coordination were consistent with the dynamics of within person interlimb coordination. By instructing the participants to rock at their own preferred tempo, Experiment 2 investigated whether the rocking chair movements of visually coupled individuals would become unintentionally coordinated. The degree to which the participants fixated on the movements of their co-actor was also manipulated to examine whether visual focus modulates the strength of interpersonal coordination. As expected, the patterns of coordination observed in both experiments demonstrated that the intentional and unintentional interpersonal coordination of rocking chair movements is constrained by the self-organizing dynamics of a coupled oscillator system. The results of the visual focus manipulations indicate that the stability of a visual interpersonal coupling is mediated by attention and the degree to which an individual is able to detect information about a co-actor's movements. 相似文献

On the interdependence of cognition and emotion 总被引:1,自引:0,他引:1
Affect and cognition have long been treated as independent entities, but in the current review we suggest that affect and cognition are in fact highly interdependent. We open the article by discussing three classic views for the independence of affect. These are (i) the affective independence hypothesis, that emotion is processed independently from cognition, (ii) the affective primacy hypothesis, that evaluative processing precedes semantic processing, and (iii) the affective automaticity hypothesis, that affectively potent stimuli commandeer attention and evaluation is automatic. We argue that affect is not independent from cognition, that affect is not primary to cognition, nor is affect automatically elicited. The second half of the paper discusses several instances of how affect influences cognition. We review experiments showing affective involvement in perception, semantic activation, and attitude activation. We conclude that one function of affect is to regulate cognitive processing. 相似文献

A total of 779 article-embedded photographs from six popular US magazines during 2004 (Newsweek, Time, Fortune, Money, People, and Sports Illustrated) were examined assessing the relationship between occupational status and gender and the depiction of men and women in print
media. Results show individuals depicted in intellectually focused occupations had higher face-to-body ratios than individuals
depicted in physically focused occupations. Gender differences in facial prominence did not reach significance. A gender by
occupation interaction indicated men in intellectually focused occupations had higher face-to-body ratios than women in similar
professions, whereas women in physical occupations had higher face-to-body ratios than men in similar occupations. This suggests
a disparity in the media with regard to displaying men and women equally in similar occupational roles. 相似文献

Richard Rorty challenges Jurgen Habermas's belief that validity-claims raised within context-bound discussions contain a moment of universality validity. Rorty argues that immersion within contingent languages prohibits any neutral, context-independent ground, that one cannot predict the defense of one's assertions before any audience, and that philosophy can no more escape its contextual limitations than strategic counterparts. Alfred Schutz's phenomenological account of motivation, the reciprocity of perspectives, and the theoretical province of meaning can articulate Habermas's intuitions.Since any claim can be analyzed from an observer's perspective for its because-motives, it can always be shown to be context-related; but to the participant involved in the in-order-to project of establishing a claim's validity, the claim appears objectively valid until counter-evidence surfaces. Rorty, even when explaining what it is to make a truth claim, resorts to the observer perspective and omits reference to the in-order-to perspective, within which alone unconditional validity becomes visible. Furthermore, the expectation that one's claim is universally valid depends not on an empirical prediction that one's claim can survive hypothesized future possible audiences. Rather, because of the reciprocity of perspectives, making possible communication and a common life, theoreticians assume that others will recognize what they take to be objective or valid, independently of diverse biographical circumstances. Finally, within the theoretical province requiring relevances different from those of everyday life, philosophy articulates claims with a greater potential to arrive at universal validity than projects that aim less universally, in spite of the fact that its theoretical context is always susceptible to because motive analysis. 相似文献

The authors systematically compared semantic and affective priming in five studies involving words and pictures. In Studies 1 (lexical decision task) and 2 (evaluation task), irrelevant short duration (200 ms) primes were briefly flashed before relevant targets. The authors orthogonally varied both the semantic and affective relations between primes and targets. In both studies, semantic priming but not affective priming was found. Study 3 revealed that the same stimuli can produce affective priming, but only when words come from a single semantic category. Studies 4 and 5 used pictures rather than words to examine automatic encoding tendencies. The results conceptually replicated those from Studies 1 and 2. In sum, the findings suggest that affective priming may be a relatively fragile phenomenon, particularly when the semantic properties of objects vary in a salient manner. 相似文献

Actions, intentions, and self-assessment: the road to self-enhancement is paved with good intentions
Actions and intentions do not always align. Individuals often have good intentions that they fail to fulfill. The studies presented here suggest that actors and observers differ in the weight they assign to intentions when deciding whether an individual possesses a desirable trait. Participants were more likely to give themselves credit for their intentions than they were to give others credit for theirs (Studies 1 and 2). This caused individuals to evaluate themselves more favorably than they evaluated others (Studies 3-5). Discussion focuses on the motivational and information-processing roots of this actor-observer difference in the weight assigned to intentions as well as the implications of this tendency for everyday judgment and decision making. 相似文献
