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

Patients with schizophrenia (SZ) show cognitive impairments on a wide range of tasks, with clear deficiencies in tasks reliant on prefrontal cortex function and less consistently observed impairments in tasks recruiting the striatum. This study leverages tasks hypothesized to differentially recruit these neural structures to assess relative deficiencies of each. Forty-eight patients and 38 controls completed two reinforcement learning tasks hypothesized to interrogate prefrontal and striatal functions and their interaction. In each task, participants learned reward discriminations by trial and error and were tested on novel stimulus combinations to assess learned values. In the task putatively assessing fronto-striatal interaction, participants were (inaccurately) instructed that one of the stimuli was valuable. Consistent with prior reports and a model of confirmation bias, this manipulation resulted in overvaluation of the instructed stimulus after its true value had been experienced. Patients showed less susceptibility to this confirmation bias effect than did controls. In the choice bias task hypothesized to more purely assess striatal function, biases in endogenously and exogenously chosen actions were assessed. No group differences were observed. In the subset of participants who showed learning in both tasks, larger group differences were observed in the confirmation bias task than in the choice bias task. In the confirmation bias task, patients also showed impairment in the task conditions with no prior instruction. This deficit was most readily observed on the most deterministic discriminations. Taken together, these results suggest impairments in fronto-striatal interaction in SZ, rather than in striatal function per se. 相似文献

Disasters and terrorism present significant and often overwhelming challenges for children and families worldwide. Individual, family, and social factors influence disaster reactions and the diverse ways in which children cope. This article links conceptualizations of stress and coping to empirical knowledge of children's disaster reactions, identifies limitations in our current understanding, and suggests areas for future study of disaster coping. Coping strategies, developmental trajectories influencing coping, and the interplay between parent and child coping represent critical areas for advancing the field and for informing programs and services that benefit children's preparedness and foster resilience in the face of mass trauma. 相似文献

This article considers the potential contribution of critical social psychology to the study of the relationship between humans and nature, particularly in terms of the role of human activities in ecological degradation. That human behaviour is having a profound impact on global climate and related phenomena has garnered broad scientific consensus and is communicated to the public in increasingly sophisticated ways. Psychology has been increasingly drawn upon by policy makers, pressure groups and related institutions in this context, in the hope of understanding, predicting and shaping behaviour and lifestyles towards more sustainable ends. In the past few decades, cognitive behaviourist models have dominated research and policy agendas concerned with identifying barriers to, and/or promoting ‘environmentally sustainable’ or ‘pro‐environmental’ behaviour. Yet despite the emergence of critical work, to date, there has been very little work in this field explicitly under the banner of critical social psychology. In this article, a brief outline of some of the tenets of critical social psychology is followed by a consideration of how these principles have been taken up in existing cross‐disciplinary critical approaches to the interrelated issues of environment, sustainability and human behaviour and the potential contribution of critical social psychology in these areas. 相似文献

Three cross-modal priming experiments examined the influence of preexposure to pictures and printed words on the speed of spoken word recognition. Targets for auditory lexical decision were spoken Dutch words and nonwords, presented in isolation (Experiments 1 and 2) or after a short phrase (Experiment 3). Auditory stimuli were preceded by primes, which were pictures (Experiments 1 and 3) or those pictures’ printed names (Experiment 2). Prime–target pairs were phonologically onset related (e.g., pijl–pijn, arrow–pain), were from the same semantic category (e.g., pijl–zwaard, arrow–sword), or were unrelated on both dimensions. Phonological interference and semantic facilitation were observed in all experiments. Priming magnitude was similar for pictures and printed words and did not vary with picture viewing time or number of pictures in the display (either one or four). These effects arose even though participants were not explicitly instructed to name the pictures and where strategic naming would interfere with lexical decision making. This suggests that, by default, processing of related pictures and printed words influences how quickly we recognize spoken words. 相似文献

Children diagnosed with reactive attachment disorder (RAD) have been reported to exhibit a multitude of symptoms and behaviors that are not captured by the Diagnostic and Statistical Manual of Mental Disorders criteria. One behavior in particular that has been the source of much argument and controversy is aggression. Although limited research on this topic does support an association between aggression and RAD behaviors, the exact nature of this link remains unclear. This study aims to fill this gap by reporting data from a study that examined the behavioral processes that occur in adopted children with RAD. Guided by the principles of grounded theory, this study employed a multi-stage semi-structured interview design. The sample consisted of 5 adoptive families, and included both adult and child participants, including the adopted children with RAD. The findings revealed 5 prominent themes: The adopted children are reported to engage in extreme and prolonged tantrums, known as rages; children were often inconsolable during these rages; these rages are perceived as uncontrollable by children with RAD; these rages are directed toward a discriminate caregiver; and the impetus for these rages appears to be associated with difficulties in adapting to environmental demands. An in-depth discussion that draws a theoretical connection between these rages and possible deficits in brain-based processes responsible for emotional regulation is presented. 相似文献

The rapid growth of employee assistance Programmes (EAPs) has not been matched by the accompanying research base of their efficacy. Given the inconsistent information relating to the effectiveness of EAPs in enhancing employee and organizational outcomes, the present review systematically appraised available evidence from organizational psychology and business databases and grey literature sources. A total of 17 studies examining the impact of EAPs, met the inclusion criteria. These were mostly from North America and utilized quantitative methodology and pre- and post-intervention designs. The majority of studies focused on EAPs offered by external providers and the counselling service, with the most common limitations being discrepancies in variable definitions and an absent comparable control group. Overall, this review found that utilizing EAPs enhanced employee outcomes, specifically improving levels of presenteeism and functioning. Absenteeism was most commonly investigated but produced mixed results. Presenteeism demonstrated a stronger effect size and greater improvement than absenteeism, suggesting presenteeism as a better variable for assessing EAP effectiveness. This review clarified parameters of existing evidence and highlighted the narrow range of measures used to date, omitting important constructs such as health and well-being and productivity. A broader evaluation capturing a wider range of variables is urgently needed. 相似文献
