Self‐efficacy (SE) is a modifiable psychosocial factor related to individuals’ beliefs in their capabilities to successfully complete courses of action and has been shown to be positively associated with task performance. The authors hypothesized that one means through which SE is related with improved performance is through enhanced task‐relevant attentional control during task execution. To assess this hypothesis, we examined the relationships between SE and behavioural and neural indices of task performance and task‐relevant attentional control for 76 young adults during the completion of a flanker task. Results showed that greater SE was associated with greater response accuracy and P3b amplitude across task conditions, and faster RT under more difficult task conditions. Additionally, P3b amplitude was found to mediate the relationship between SE and task performance in the difficult condition. These findings suggest that greater attentional allocation to task‐relevant processes, including monitoring stimulus‐response relationships and focusing attention on working memory operations, may help explain the association between SE and improved task performance.  相似文献

A land use many‐objective optimization problem for a 1500‐ha farm with 315 paddocks was formulated with 14 objectives (maximizing sawlog production, pulpwood production, milksolids, beef, sheep meat, wool, carbon sequestration, water production, income and Earnings Before Interest and Tax; and minimizing costs, nitrate leaching, phosphorus loss and sedimentation). This was solved using a modified Reference‐point‐based Non‐dominated Sorting Genetic Algorithm II augmented by simulated epigenetic operations. The search space had complex variable interactions and was based on economic data and several interoperating simulation models. The solution was an approximation of a Hyperspace Pareto Frontier (HPF), where each non‐dominated trade‐off point represented a set of land‐use management actions taken within a 10‐year period and their related management options, spanning a planning period of 50 years. A trade‐off analysis was achieved using Hyper‐Radial Visualization (HRV) by collapsing the HPF into a 2‐D visualization capability through an interactive virtual reality (VR)‐based method, thereby facilitating intuitive selection of a sound compromise solution dictated by the decision makers' preferences under uncertainty conditions. Four scenarios of the HRV were considered emphasizing economic, sedimentation and nitrate leaching aspects—giving rise to a triple bottomline (i.e. the economic, environmental and social complex, where the social aspect is represented by the preferences of the various stakeholders). Highlights of the proposed approach are the development of an innovative epigenetics‐based multi‐objective optimizer, uncertainty incorporation in the search space data and decision making on a multi‐dimensional space through a VR‐simulation‐based visual steering process controlled at its core by a multi‐criterion decision making‐based process. This approach has widespread applicability to many other ‘wicked’ societal problem‐solving tasks. Copyright © 2014 John Wiley & Sons, Ltd.  相似文献

In the pursuit of well‐being at work, work stress is always an inescapable challenge. However, existing research shows that the relationships between work stress and employee outcomes are inconsistent, which indicates that the concept of work stress needs further investigation. Moreover, Zhong‐Yong serves as a cognitive strategy to coping with stress as well as being a pivotal life wisdom and practical rationality. Using a questionnaire survey, this study explores the relationship between work stress, employee well‐being, and Zhong‐Yong beliefs. The work stress was classified into challenge‐ and hindrance‐related stress while emotional exhaustion and job satisfaction were used as well‐being indicators. Using a sample of 394 employees from private enterprises in Taiwan as subjects, the results show that (1) hindrance‐related stress is destructive to employee well‐being; (2) challenge‐related stress is positively associated with emotional exhaustion but has no significant relation with job satisfaction; (3) Zhong‐Yong beliefs mitigate the harm from hindrance‐related stress on employee well‐being; and (4) Zhong‐Yong beliefs weaken the negative effects of challenge‐related stress on emotional exhaustion, and transform challenge‐related stress into eustress for job satisfaction.  相似文献

Outsourcing is an increasingly significant topic pursued via corporations seeking enhanced efficiency. Third‐party reverse logistics involves the employ of external firms to carry out some or all of the firm's logistics activities. Output‐oriented super slacks‐based measure (SBM) model is one of the models in data envelopment analysis (DEA). In many real‐world applications, data are often stochastic. A successful approach to address uncertainty in data is to replace deterministic data via random variables, leading to chance‐constrained DEA. In this paper, a chance‐constrained output‐oriented super SBM model is developed and also its deterministic equivalent, which is a nonlinear program, is derived. Furthermore, it is shown that the deterministic equivalent of the stochastic output‐oriented super SBM model can be converted into a quadratic program. In addition, sensitivity analysis of the stochastic output‐oriented super SBM model is discussed with respect to changes on parameters. Finally, a numerical example demonstrates the application of the proposed model. Copyright © 2011 John Wiley & Sons, Ltd.  相似文献

We examined how a friend's presence affects a performer's prefrontal activation in daily‐life activities using two wireless portable near‐infrared spectroscopy (NIRS) devices. Participants played a driving video game either solely in the single group or with a friend in the paired group. The two groups (single and paired) were subdivided according to their game proficiency (low and high). The NIRS data demonstrated a significant interaction of group by proficiency. Low‐proficiency players in the paired group showed lower activation than those in the single group, but high‐proficiency players did not. In the paired group, high‐proficiency players showed higher activation than low‐proficiency players, but not in the single group. These results suggest that NIRS detects social presence effects in everyday situations: decreasing prefrontal activation in low‐proficiency performers due to tension reduction and increasing prefrontal activation in high‐proficiency performers due to increased arousal.  相似文献

The Social Problem Solving Inventory‐Revised Short‐Form (SPSI‐R:SF) has been used in several countries to identify problem‐solving deficits among clinical and general populations in order to guide cognitive‐behavioural interventions. Yet, very few studies have evaluated its psychometric properties. Three language versions of the questionnaire were administered to a general population sample comprising 1000 participants (771 English‐, 178 Afrikaans‐ and 101 Xhosa‐speakers). Of these participants, 210 were randomly selected to establish test–retest reliability (70 in each language). Principal component analysis was performed to examine the applicability of the factor structure of the original questionnaire to the South African data. Supplementary psychometric analyses were performed, including internal consistency and test–retest reliability. Collectively, results provide initial evidence of the reliability and validity of the SPSI‐R:SF for the assessment of problem solving deficits in South Africa. Further studies that explore how the Afrikaans language version of the SPSI‐R:SF can be improved and that establish the predictive validity of scores on the SPSI‐R:SF are needed.  相似文献

Sociobiology is a grand narrative of evolutionary biology on which to build unified knowledge. Consilience is a metaphorical representation of that narrative. I take up the same metaphor but apply it differently. I evoke the image of jumping together, not on solid ground but on the strong, flexible canvas sheet of a trampoline, on which natural sciences, social sciences, and the humanities jump together. This image overlaps with the traditional East Asian way of understanding—that is, the “Heaven‐Earth‐Person Triad.” Using recent insights from cognitive science—metaphor, embodiment, and conceptual blending—I propose the alternative way of “bio‐socio‐humanities” to understand and experience the world.  相似文献

Simple and conditional discrimination training may produce various types of controlling relations. Responses may be controlled primarily by the positive stimulus (select–control relation) or by the negative stimulus (reject–control relation; the subject excludes the negative stimulus and chooses the positive). Bees learn to respond in simple and conditional discriminations. However, no study has searched for reject–control responding in Melipona bees. We trained Melipona quadrifasciata on a simple discrimination task (S+ vs. S‐; e.g., blue vs. yellow) and then probed for stimulus control with two types of probe trials, S+ versus a new stimulus (Select–control probes) and S‐ versus a new stimulus (Reject–control probes). For Group Different, a new‐stimulus color (e.g., white) was used in one type of probe and another color (e.g., black) was used in the other type. For Group Same, a single new‐stimulus color was used in both types of probes. On Select probes, the bees always preferred S+ to the new stimulus. On Reject probes, results were mixed. Depending on the colors used in training and probing, bees responded to both stimuli, and even preferred the S‐. The data suggest no control by the negative function of the S‐ and support the select‐stimulus control hypothesis of responding.  相似文献

An intermediate step is introduced to the dialogue decision process for decision analysis. Alternatives are refined after they have been generated within a strategy table but before they are subject to more detailed evaluation. Two or more judges create a subjective mapping from alternatives to attributes that will later be mapped to criteria. In strategy tables, each of the alternative strategies consists of a coherent set of choices made across several decisions that are to be coordinated. These strategic alternatives are modified so as to increase their differentiation in the attribute space, rather than in the decision space alone. When criteria weights are unknown, the best alternative from the modified set may be superior to the best alternative from the original set. Furthermore, analysis of the resulting alternatives may yield a better mapping of the value response surface for the action space, in the sense that this mapping leads to eventual construction of a higher value alternative. Results are reported for a consulting engagement incorporating the proposed step. Copyright © 2003 John Wiley & Sons, Ltd.  相似文献

Infants change their behaviours in accordance with the objects they are exploring. They also tailor their exploratory actions to the physical context. This selectivity of exploratory actions represents a foundational cognitive skill that underlies higher‐level cognitive processes. The present study compared the development of selective exploratory behaviours in high and low socio‐economic status (SES) infants. Sixty‐one 6–8‐ and 10–12‐month‐old infants were presented with rigid and flexible cubes on a tray that was half rigid and half flexible. There were SES effects for each category of exploratory behaviours: object only, surface only and object–surface interactions. Low‐SES infants engaged in comparable amounts of exploratory behaviours with high‐SES infants, but they exhibited behaviours less conducive to information uptake, compared with high‐SES infants. The results suggest difficulty for low‐SES infants in transitioning to more mature exploration strategies. Copyright © 2015 John Wiley & Sons, Ltd.  相似文献

The goal of this study was to propose a new functional magnetic resonance imaging (fMRI) paradigm using a language‐free adaptation of a 2‐back working memory task to avoid cultural and educational bias. We additionally provide an index of the validity of the proposed paradigm and test whether the experimental task discriminates the behavioural performances of healthy participants from those of individuals with working memory deficits. Ten healthy participants and nine patients presenting working memory (WM) deficits due to acquired brain injury (ABI) performed the developed task. To inspect whether the paradigm activates brain areas typically involved in visual working memory (VWM), brain activation of the healthy participants was assessed with fMRIs. To examine the task's capacity to discriminate behavioural data, performances of the healthy participants in the task were compared with those of ABI patients. Data were analysed with GLM‐based random effects procedures and t‐tests. We found an increase of the BOLD signal in the specialized areas of VWM. Concerning behavioural performances, healthy participants showed the predicted pattern of more hits, less omissions and a tendency for fewer false alarms, more self‐corrected responses, and faster reaction times, when compared with subjects presenting WM impairments. The results suggest that this task activates brain areas involved in VWM and discriminates behavioural performances of clinical and non‐clinical groups. It can thus be used as a research methodology for behavioural and neuroimaging studies of VWM in block‐design paradigms.  相似文献

Samuel Langhorne Clemens (Mark Twain; 1835–1910), American humorist and writer, followed scientific and medical developments, and relished exposing questionable practices and ideas. In his youth, he pondered how phrenologists were assessing character, and in 1855 he copied sections of a phrenology book and a skull diagram into a notebook. Later, in London, he had two phrenological examinations by Lorenzo Fowler—one without and the other after identifying himself. Following his “test,” which produced contrasting results, he began to ridicule phrenologists and phrenology in Tom Sawyer, Huckleberry Finn, and other works. He underwent at least two more head readings in the United States, and in Eddypus, an unfinished work from 1901 to 1902, he maintained that phrenologists base their insights primarily on how people dress and answer questions. Although now lampooning the craniological tenets of phrenology, Twain never seemed to reject the idea of distinct faculties of mind associated with specialized brain organs.  相似文献

As an academic discipline as well as in practice, decision support is one of the most important functions of management accounting and control (MAC). Owing to decision settings' increasing complexity, suitable multiple criteria methods are becoming increasingly important for MAC. We, therefore, examine the extent to which certain multiple criteria decision‐making (MCDM) methods are used in the MAC context. In order to do so, we undertook an extensive bibliometric analysis of the management accounting field during the last three decades. The results indicate an increase in the importance of MCDM. Furthermore, recent research activities were classified into different areas of decision‐making within MAC since the majority of publications deal with the areas of strategic management, budgeting and performance management. More specifically, strategy and performance evaluation, strategic planning and the selection of alternatives are the most prominent MCDM applications. Our analysis reveals that the analytic hierarchy process (AHP) is the most popular analytical tool with which to support management in complex decision‐making situations. The results of the study prove that technical MAC literature does not cover a desirable range of MCDM applications and that the AHP, as well as the analytic network process (ANP) are of increasing importance in respect of the international scope of MAC. Therefore, the area of MCDM continues to be an active part of management science research and application, specifically of MAC. Copyright © 2011 John Wiley & Sons, Ltd.  相似文献

Research indicates that patients with Obsessive Compulsive Disorder (OCD) frequently suffer from comorbid sleep difficulties, and that these difficulties often are not clinically recognized and diagnosed. There has been limited research investigating if comorbid sleep difficulties impair treatment outcome for OCD and if the sleep difficulties change following OCD‐treatment. Thirty‐six patients with obsessive compulsive disorder underwent concentrated exposure treatment delivered in a group over four consecutive days and were assessed with measures of OCD, depressive symptoms and sleep disturbance at three different time points (pre, post and 6 months follow‐up). The sample was characterized by a high degree of comorbidity with other psychiatric disorders. At pre‐treatment nearly 70% of the patients reported sleep difficulties indicative of primary insomnia. The results showed that patients had large reductions of OCD‐symptoms as well as significant improvements in sleep disturbance assessed after treatment, and that these improvements were maintained at follow‐up. Sleep disturbance did not impair treatment outcome, on the contrary patients with higher degree of sleep disturbance at pre‐treatment had better outcome on OCD‐symptoms after treatment. The results indicated that the majority of the OCD sample suffered from sleep disturbances and that these sleep disturbances were significantly reduced following adequate treatment of OCD without specific sleep interventions. However, a proportion of the patients suffered from residual symptoms of insomnia after treatment.  相似文献

The Pairwise Comparison‐based Preference Measurement (PCPM) approach has been proposed for products featuring a large number of attributes. In the PCPM framework, a static two‐cyclic design is used to reduce the number of pairwise comparisons. However, adaptive questioning routines that maximize the information gained from pairwise comparisons promise to further increase the efficiency of this approach. This paper introduces a new adaptive algorithm for PCPM, which accounts for several response errors. The suggested approach is compared with an adaptive algorithm that was proposed for the Analytic Hierarchy Process as well as a random selection of pairwise comparisons. By means of Monte Carlo simulations, we quantify the extent to which the adaptive selection of pairwise comparisons increases the efficiency of the respective approach.

Belief bias is the tendency to accept conclusions that are compatible with existing beliefs more frequently than those that contradict beliefs. It is one of the most replicated behavioral findings in the reasoning literature. Recently, neuroimaging studies using functional magnetic resonance imaging (fMRI) and event‐related potentials (ERPs) have provided a new perspective and have demonstrated neural correlates of belief bias that have been viewed as supportive of dual‐process theories of belief bias. However, fMRI studies have tended to focus on conclusion processing, while ERPs studies have been concerned with the processing of premises. In the present research, the electrophysiological correlates of cognitive control were studied among 12 subjects using high‐density ERPs. The analysis was focused on the conclusion presentation phase and was limited to normatively sanctioned responses to valid–believable and valid–unbelievable problems. Results showed that when participants gave normatively sanctioned responses to problems where belief and logic conflicted, a more positive ERP deflection was elicited than for normatively sanctioned responses to nonconflict problems. This was observed from ?400 to ?200 ms prior to the correct response being given. The positive component is argued to be analogous to the late positive component (LPC) involved in cognitive control processes. This is consistent with the inhibition of empirically anomalous information when conclusions are unbelievable. These data are important in elucidating the neural correlates of belief bias by providing evidence for electrophysiological correlates of conflict resolution during conclusion processing. Moreover, they are supportive of dual‐process theories of belief bias that propose conflict detection and resolution processes as central to the explanation of belief bias.  相似文献

McGinn (2015) and Fernández‐Álvarez, Castañeiras, and Wyss (2015) make valuable suggestions in their commentaries on the three self‐practice/self‐reflection (SP/SR) articles in this issue of the Australian Psychologist. In our response, we use their commentaries as a springboard to highlight contextual influences and challenges for future SP/SR research, and suggest potential ways forward.  相似文献

Time‐of‐day variation of visuo‐spatial attention in relation to body temperature and subjective arousal was assessed. At five different times of day, alertness, covert, and overt orienting of attention were assessed in fifteen healthy subjects. Based on previous studies reporting a tight coupling of alerting and orienting the present study investigates potential attentional asymmetries induced by diurnal variations of arousal. Both covert and overt orienting of attention improved in the course of the day. However, no asymmetries between left and right visual hemifields could be detected. Covert orienting additionally covaried with body temperature, indicating a quite close relation between the attentional arousal and orienting system. Conversely, overt orienting only improved due to repeated testing but did not correlate with body temperature suggesting a partial independence of both modes of attentional orienting. It can be assumed that due to limited diurnal variations of arousal in the participants and practice effects caused by repeated testing, no attentional asymmetries could be provoked.  相似文献
