I respond to Vladas Griskevicius and Douglas T. Kendrick (G&;K) and Gad Saad's (S) defenses of the view that Consumer Studies would benefit from the appeal to evolution in all work aimed at understanding consumer behavior. I argue that G&;K and S's reliance on one theoretical perspective, that of evolutionary psychology, limits their options. Further, I point out some specific problems with the theoretical perspective of evolutionary psychology. Finally, I introduce some alternative evolutionary approaches to studying human behavior that could profitably be adopted in consumer research. 相似文献

We show that time priming leads consumers to adopt an alternative-based evaluation strategy, whereas money priming elicits the use of an attribute-based evaluation strategy. In Experiment 1, we used process tracing in Mouselab to test this proposition, and the results suggested that the effect of time versus money priming on the choice of product-evaluation strategy was mediated by a holistic versus piecemeal information-processing. The results of Experiments 2A and 2B showed that the use of time versus money priming to trigger the choice of an alternative-based versus attribute-based evaluation strategy may result in systematic preference reversals. Specifically, when time (versus money) was primed, the participants were found to be more likely to choose a product dominating on a verbally described (versus numerically described) attribute (Experiment 2A), and one dominating on a non-alignable (versus alignable) attribute (Experiment 2B). 相似文献

The commentaries raise questions about modularity, and about the evidence required to establish evolutionary influences on behavior. We briefly discuss evidence leading evolutionary psychologists to assume that human choices reflect evolutionary influences, and to assume some degree of modularity in human information processing. An evolutionary perspective is based on a multidisciplinary nomological network of evidence, and results of particular experiments are only one part of that network. The precise nature of, and number of, information processing systems, is an empirical question. Consumer psychologists need not retrain as biologists to profit from using insights and findings from evolutionary biology to generate new hypotheses, and to contribute novel insights and findings to the emerging nomological network of modern evolutionary science. 相似文献

We conduct three experiments in which participants in dyads choose between two restaurants, each of which is preferred by only one participant, and one participant has the power to decide which restaurant both will patronize. We find that the power to make a joint decision increases satisfaction with the choice only when those involved have a competitive decision orientation, a weak or anonymous relationship, and the outcome they choose is subsequently available. Participants who have a cooperative orientation are satisfied whether or not they have power and whether or not the resulting choice is consistent with their initial preferences. 相似文献

Making the right choice depends crucially on the accurate valuation of the available options in the light of current needs and goals of an individual. Thus, the valuation of identical options can vary considerably with motivational context. The present study investigated the neural structures underlying context dependent evaluation. We instructed participants to choose from food menu items based on different criteria: on their anticipated taste or on ease of preparation. The aim of the manipulation was to assess which neural sites were activated during choice guided by incentive value, and which during choice based on a value-irrelevant criterion. To assess the impact of increased motivation, affect-guided choice and cognition-guided choice was compared during the sated and hungry states. During affective choice, we identified increased activity in structures representing primarily valuation and taste (medial prefrontal cortex, insula). During cognitive choice, structures showing increased activity included those implicated in suppression and conflict monitoring (lateral orbitofrontal cortex, anterior cingulate). Hunger influenced choice-related activity in the ventrolateral prefrontal cortex. Our results show that choice is associated with the use of distinct neural structures for the pursuit of different goals. 相似文献

The present analysis reveals the social comparison bias – a bias that emerges from the social comparison process and taints recommendations. We hypothesize that people who have high standing on a relevant dimension (e.g., quantity of publications) begin to protect their social comparison context by making recommendations that prevent others, who might surpass them on the relevant dimension, from entering their comparison context. Studies 1 and 2 instantiate this effect in both hypothetical and real decision situations, showing that people tend not to recommend individuals who surpass them on the relevant dimension on which they have high standing. Finally, Study 3, in a sample of real employees, links the effect to one’s concern for protecting self-esteem. Theoretical and organizational implications are discussed. 相似文献

Although recent economic models of human decision making have recognised the role of emotion as an important biasing factor, the impact of incidental emotion on decisions has remained poorly explored. To address this question, we jointly explored the role of emotional valence (i.e., positive vs. negative) and motivational direction (i.e., approach vs. avoidance) on performance in a well-known economic task, the Ultimatum Game. Participants had to either accept or reject monetary offers from other players, offers that vary in their degree of unfairness. A main effect of motivational direction, but not valence, was observed, with withdrawal-based emotion (disgust and serenity) prompting more rejections relative to approach-based emotion (anger and amusement) and a neutral state. These results further confirm that subtle incidental moods can bias decision making, and suggest that motivational state may be a useful framework to study such decisions. Implications with regard to emotion, cognitive neuroscience, and clinical psychology are discussed. 相似文献

Motor vehicle crashes (MVCs) are a major contributor to adolescent mortality. Adolescent drivers are more likely to make risky decisions in the presence of peers. However, rewards have also been shown to improve decision making in adolescence. Our goal was to determine if peer observation and reward effects on decision-making were dependent upon adolescent driving styles.Twenty-four healthy adolescents played a driving game in a 2 (no peer; peer) × 2 (no rewards; rewards) within-subjects experiment. Driving styles were measured by self-report.Rewards favoring safe choices reduced risky decision making, but this effect was especially robust for adolescents with driving styles that increase risk of MVCs (i.e., dangerous, fast, angry, or distracted styles). Findings suggest that rewards for safe driving can be an effective mechanism for reducing MVCs, especially for the most at-risk drivers, if they can be made appetizing to adolescents. 相似文献

Five studies show that gift recipients are more appreciative of gifts they explicitly request than those they do not. In contrast, gift givers assume that both solicited and unsolicited gifts will be equally appreciated. At the root of this dilemma is a difference of opinion about what purchasing an unsolicited gift signals: gift givers expect unsolicited gifts will be considered more thoughtful and considerate by their intended recipients than is actually the case (, and ). In our final two studies, we highlight two boundary conditions for this effect: identifying a specific gift and using money as a gift. When gift recipients request one specific gift, rather than providing a list of possible gifts, givers become more willing to purchase the requested gift (Study 4). Further, although givers believe that recipients do not appreciate receiving money as much as receiving a solicited gift, recipients feel the opposite about these two gift options (Study 5). 相似文献

The MARS (Masking Action Relevant Stimuli) method assesses information demand for dynamic stimuli while driving. An action relevant stimulus is masked and the driver presses a button to unmask the stimulus for a limited period. We interpreted button presses as information demand. Following our previous research (Rittger, Kiesel, Schmidt, & Maag, 2014), the current study further evaluates the method. We applied the MARS method to a dynamic in-vehicle display containing recommendations from a traffic light assistant. In a driving simulator, drivers approached intersections with different traffic light phasing. The display either presented simple or complex information. In half of the drives, the participants used the MARS method. The study had a full within subjects design and fixations were recorded in all conditions. The results showed that the information demand varied according to the information in the display and the traffic light phase. A comparison of button presses with fixations showed that one unmasking interval came along with one fixation on the display. As a conclusion, the MARS method can distinguish between conditions with high and low information demand for the display. Button presses relate to fixations on the display. Hence, the MARS method is a promising tool to assess the information demand in dynamic environments and can be applied as an extension or alternative for eye tracking. 相似文献

A portfolio forecasting model based on particle swarm optimization (PSO) algorithm with automatic factor scaling is proposed in this Article to effectively improve the accuracy of related analysis model in portfolio application. Firstly, the portfolio problem is analyzed and a hybrid constraint portfolio model is obtained by improving portfolio model with consideration of general portfolio model and combination of market value constraint and upper bound constraint according to Markowitz's theory. Secondly, PSO algorithm is introduced during analysis on portfolio model and solution is found with the hybrid constraint portfolio model of PSO on portfolio. In addition, in order to further improve the performance of PSO in model solution, automatic factor scaling is used for adaptive learning on parameters associated with PSO, to improve convergence of the algorithm. At last, simulation experiments show that the algorithm proposed can obtain a more ideal investment portfolio scheme, thereby reducing investment risks and obtaining greater investment returns. 相似文献

Posture-related affordances guide attacks in basketball 总被引:1,自引:0,他引:1

Objectives
The purpose of this study was to investigate the decision made by the attacker to drive to the left or right of the defender.Method
Participants were 32 novice and intermediate basketball players who were assigned the role of attacker or defender in a one-on-one subphase. We manipulated the defender’s posture and measured both the postures of defenders and attackers and the ensuing decision on drive direction.Results
As hypothesized, the posture of defenders guided the decision behavior of the attacker. Both novice and intermediate attackers made the same affordance-based decision by driving to the side of the defender’s most advanced foot, but only when the distance between attacker and defender was small. Moreover, novice attackers conveyed postural information regarding their upcoming drive direction while intermediate attackers were better able to conceal this information.Conclusions
These results lend further support to the notion of information-based control of interpersonal actions in sport contexts. 相似文献13.

An unsolved fundamental problem in decision science concerns the extent to which the nature of the perceived relationships among items in a set of alternatives influences how they are chosen. More specifically, given a choice set with n items, how does human choice behavior differ as a function of the perceived relationships between the items of the set? In what follows, we study this problem empirically and theoretically from the standpoint of the dimensional structure of the choice set. In particular, we use generalized invariance structure theory (GIST; Vigo, 2013, 2014) to propose an inverse relationship between the degree of concept learning difficulty of a choice set (as determined by its degree of invariance or internal coherence) and choice response times on its members. To our knowledge, this is the first model that precisely unifies these two fundamental constructs. On average, the model, without free parameters, accounts for nearly 90% of the variance in the data from our two response-time experiments. 相似文献

Research suggests that attention is attracted to evolutionary threats (e.g., snakes) due to an evolved “fear-module” that automatically detects biological threats to survival. However, recent evidence indicates that non-evolutionary threats (e.g., guns) capture and hold attention as well, suggesting a more general “threat-relevance” mechanism that directs attentional resources toward any potential danger in the environment. The current research measured how selective attentional resources were influenced both by the type of threat (e.g., snake vs. gun) and by the context in which the threat was encountered. Participants were primed with either natural or human-made environments to assess how these contexts influence attention to evolutionary and non-evolutionary threats, as measured by a spatial-cueing task. The results indicate that whether biological or non-biological threats receive greater attentional processing is determined by the context in which they are encountered. 相似文献

Recycling, evolution and the structure of human personality 总被引:1,自引:0,他引:1
Concomitant with the recent surge in environmental awareness of the industrialized world, social scientists have begun searching for the determinants of recycling behavior. Although the efforts of these scientists – most notably, environmental psychologists – are commendable, they have as yet not isolated the strategies by which long-term recycling can be effectively encouraged. In this article, I comment that by giving proper attention to the evolved structure of human personality, the emerging paradigm of evolutionary psychology may have something to offer those wishing to encourage durable and generalizable recycling behavior. 相似文献

Poulton and Menzies have articulated a nonassociative alternative to traditional conditioning theories of phobia emergence. Prompted by their essay, I address several issues including controversies about what counts as a conditioning event, difficulties establishing whether a fear functioned as an adaptation throughout evolutionary history, hazards of attempting to recover conditioning events in the histories of patients, and problems with the contingency view of associative learning. 相似文献

Recent developments in evolutionary psychology suggest that living among others of the same ethnicity might make individuals happier and further that such an effect of the ethnic composition on life satisfaction may be stronger among less intelligent individuals. Data from the National Longitudinal Study of Adolescent Health showed that White Americans had significantly greater life satisfaction than all other ethnic groups in the US and this was largely due to the fact that they were the majority ethnic group; minority Americans who lived in counties where they were the numerical majority had just as much life satisfaction as White Americans did. Further, the association between ethnic composition and life satisfaction was significantly stronger among less intelligent individuals. The results suggest two important factors underlying life satisfaction and highlight the utility of integrating happiness research and evolutionary psychology. 相似文献
