Recent years have seen a rejuvenation of interest in studies of motivation–cognition interactions arising from many different areas of psychology and neuroscience. The present issue of Cognitive, Affective, & Behavioral Neuroscience provides a sampling of some of the latest research from a number of these different areas. In this introductory article, we provide an overview of the current state of the field, in terms of key research developments and candidate neural mechanisms receiving focused investigation as potential sources of motivation–cognition interaction. However, our primary goal is conceptual: to highlight the distinct perspectives taken by different research areas, in terms of how motivation is defined, the relevant dimensions and dissociations that are emphasized, and the theoretical questions being targeted. Together, these distinctions present both challenges and opportunities for efforts aiming toward a more unified and cross-disciplinary approach. We identify a set of pressing research questions calling for this sort of cross-disciplinary approach, with the explicit goal of encouraging integrative and collaborative investigations directed toward them. 相似文献

The current research demonstrates that retailer size moderates the positive effect of corporate social responsibility (CSR) initiatives on consumer outcomes such as increased purchase intentions and perceptions of CSR. Retailer size is introduced as a factor that leads consumers to respond more positively to small retailers' CSR activities, relative to CSR from large retailers. We also provide support for the ability of consistency/commitment to CSR to serve as a means by which larger retailers can counter their size liability. We replicate and generalize these results across multiple CSR forms. Implications for retail management and future research are discussed. 相似文献

Excessive alcohol consumption has a vast, negative impact on society. Rodent models have been successful in furthering our understanding of the biological underpinnings that drive alcohol consumption. Rodents emit ultrasonic vocalizations (USVs) that are each composed of several acoustic characteristics (e.g., frequency, duration, bandwidth, power). USVs reflect neurotransmitter activity in the ascending limb of the mesolimbic dopaminergic and cholinergic neurotransmitter systems and serve as noninvasive, real-time biomarkers of dopaminergic and cholinergic neurotransmission in the limbic system. In the present study, we recorded spontaneously emitted USVs from alcohol-naïve Long-Evans (LE) rats and then measured their alcohol intake. We compared the USV acoustic characteristics and alcohol consumption data from these LE rats with previously published data from selectively bred high-alcohol (P and HAD-1) and low-alcohol (NP and LAD-1) drinking lines from studies with the same experimental method. Predictive analytic techniques were applied simultaneously to this combined data set and revealed that (a) USVs emitted by alcohol-naïve rats accurately discriminated among high-alcohol consuming, LE, and low-alcohol consuming rat lines, and (b) future alcohol consumption in these same rat lines was reliably predicted from the USV data collected in an alcohol-naïve state. To our knowledge, this is the first study to show that alcohol consumption is predicted directly from USV profiles of alcohol-naïve rats. Because USV acoustic characteristics are sensitive to underlying neural activity, these findings suggest that baseline differences in mesolimbic cholinergic and dopaminergic tone could determine the propensity for future alcohol consumption in rodents. 相似文献

Theory and research indicates that individuals with more frequent positive emotions are better at attaining goals at work and in everyday life. In the current study we examined whether the expression of genuine positive emotions by scientists was positively correlated with work-related accomplishments, defined by bibliometric (e.g. number of citations) and sociometric (number of followers for scholarly updates) indices. Using a sample of 440 scientists from a social networking site for researchers, multiple raters coded smile intensity (full smile, partial smile, or no smile) in publicly available photographs. We found that scientists who presented a full smile had the same quantity of publications yet of higher quality (e.g. citations per paper) and attracted more followers to their updates compared to less positive emotionally expressive peers; results remained after controlling for age and sex. Thin-slicing approaches to the beneficial effects of positive emotionality offer an ecologically valid approach to complement experimental and longitudinal evidence. Evidence linking positive emotional expressions to scientific impact and social influence provides further support for broaden and build models of positive emotions. 相似文献

Many competitions, such as political campaigns, innovative endeavors, sports, or courting rituals, require investment of nonrefundable resources: One contestant wins the prize for the invested amount, whereas all others lose their investments without receiving compensation. Frequently, contests are asymmetric, because of differing resources or prize valuations. Does asymmetry discourage the weaker contestants from investing? Do stronger contestants take this into account and also invest less? Or does the desire to win abolish these differences? Two experiments explored the effects of asymmetry between the contestants—arising from their resources or prizes—on nonrefundable investments. Subjects repeatedly competed in both symmetric and asymmetric contests, enabling within‐subject comparisons. We observed an effect of asymmetry only when it concerned resources: Subjects overall invested less when their resources were unequal, whereas inequality in the prizes did not influence investments. This pattern suggests that winning itself is motivating. The changes between consecutive investments can be explained by reactions to the previous outcome (win or loss): Across all contests, investment decreased following a win and increased following a loss.

Previous research has described an apparent shift in perceived interpersonal power towards equality between men and women later in life. This study investigated (a) whether the shift in power with age would appear in the Israeli kibbutz, (b) the role of the parental emergency in the shift, and (c) whether changes in behaviors or attitudes best account for the shift. One hundred twenty younger and older Israeli women and men, half from the city and half from the kibbutz, wrote TAT stories, which were then rated for overall power of the female and male characters, their power strategies, and their motives. A shift in perceived power with age was found in both the city and the kibbutz. Parental status reduced the power of the woman and increased the power of the man only in the city, whereas the reverse was true in the kibbutz. These results counter the parental emergency explanation for the shift in power with age. Furthermore, older women used traditionally feminine power strategies, but their behavior was evaluated as more powerful than the same behavior in younger women. Thus, it is not the behaviors but rather people's evaluation of the behaviors that changes across the life span of the individual. 相似文献

In two experiments hungry rats showed enhanced preference for a flavour as a result of a procedure whereby the flavour followed presentation of 10% glucose—i.e. the reverse of the usual sequence. This provides the first example of excitatory conditioning resulting from reversed pairing involving an appetitive reinforcer. Experiment 1 compared a Cinnamon group, for which ingestion of glucose was followed after 3 min by cinnamon and on other days water was followed by wintergreen, with a Wintergreen group in which wintergreen followed glucose and cinnamon followed water. In a final 2-bottle test relative preference for cinnamon was greater in the Cinnamon than in the Wintergreen group. This effect was replicated in Experiment 2, which compared an Immediate group, for which, as above, drinking glucose was followed 3 min later by access to cinnamon, with a Delay group, for which there was a delay of 1 hr between glucose and subsequent access to cinnamon. Enhanced preference for cinnamon was found only in the Immediate group and appeared after only four glucose-cinnamon pairings. An important finding came from a choice test between glucose and saccharin in which the Immediate group showed a weaker preference for glucose than the Delay group. This indicated that a novel flavour may overshadow the association between the flavour of glucose and its consequences, which normally serves to enhance preference for glucose. 相似文献

Treatment and rehabilitation of the cognitive, psychological, and motor sequelae of central nervous system dysfunction often relies on assessment instruments to inform diagnosis and to track changes in clinical status. Typically, these assessments employ paper-and-pencil psychometrics, hands-on analog/computer tests, and rating of behavior within the context of real-world functional environments. Virtual reality offers the option to produce and distribute identical "standard" simulation environments in which performance can be measured and rehabilitated. Within such digital scenarios, normative data can be accumulated for performance comparisons needed for assessment/diagnosis and for treatment/rehabilitation purposes. In this manner, reusable archetypic virtual environments constructed for one purpose can also be applied for applications addressing other clinical targets. This article will provide a review of such a retooling approach using a virtual classroom simulation that was originally developed as a controlled stimulus environment in which attention processes could be systematically assessed in children with attention-deficit/hyperactivity disorder. This system is now being applied to other clinical targets including the development of tests that address other cognitive functions, eye movement under distraction conditions, social anxiety disorder, and the creation of an earthquake safety training application for children with developmental and learning disabilities. 相似文献

Experiential avoidance as a generalized psychological vulnerability: comparisons with coping and emotion regulation strategies 总被引:1,自引:0,他引:1
Extending previous work, we conducted two studies concerning the toxic influences of experiential avoidance (EA) as a core mechanism in the development and maintenance of psychological distress, and disruption of pleasant, engaging, and spontaneous activity. Of particular interest was whether EA accounted for relationships between coping and emotion regulation strategies on anxiety-related pathology (Study 1) and psychological distress and hedonic functioning over the course of a 21-day monitoring period (Study 2). In Study 1, EA mediated the effects of maladaptive coping, emotional responses styles, and uncontrollability on anxiety-related distress (e.g., anxiety sensitivity, trait anxiety, suffocation fears, and body sensation fears). In Study 2, EA completely mediated the effects of two emotion regulation strategies (i.e., suppression and reappraisal) on daily negative and positive experiences and was associated with diminished daily positive affective experiences and healthy life appraisals, diminished frequency of positive events and more frequent negative life events, and greater negative affective experiences. The present data show that cognitive reappraisal, a primary process of traditional cognitive-behavior therapy, was much less predictive of the quality of psychological experiences and events in everyday life compared with EA. Further consideration of experiential avoidance as a generalized diathesis and toxic process will be useful in improving our understanding of the etiology, phenomenology, and treatment of anxiety conditions, general human suffering, and disruptions in hedonic capacity. 相似文献
