Although work represents an important achievement setting, research on the perceived motivational climate, as defined by the achievement goal theory (AGT), remains limited. Calls have been made for research on the salience of such situational influences based on traditional AGT. Therefore, the aim of this research was to develop a scale to measure the motivational climate at work. In a pilot study, participants completed a developed questionnaire and the findings supported psychometric properties of the questionnaire. Two further studies were conducted and the findings provided evidence of content validity, criterion‐related validity, construct validity, and internal consistency. The findings suggest the questionnaire might be used to determine the perception of the extant motivational climate in the workplace.  相似文献

The purpose of this study was to examine the journalist-athlete relationship at a major competitive event to better understand how the media may be perceived as a source of strain and how elite athletes cope with the media demands. Ten participants were interviewed after the 2010 Vancouver Olympic Winter Games. Intrusive questioning may negatively affect and influence the athlete's preparation for events. The use of coping strategies to deal with the media demands and reporting becomes important. In addition, the team support personnel should employ mastery motivational strategies to keep the athlete task involved.  相似文献

Using a cued conjunction search task, Anderson, Heinke, and Humphreys (2010) demonstrated larger effects from cueing target colour than from cueing target orientation. In this study, we separated the implicit (nonexpectation-dependent) and explicit (expectation-dependent) effects of orientation and colour visual cues. In Experiment 1, we replicated the original findings for short cue durations (100–200 ms), demonstrating that cues matching the physical property of the target on 80% of trials exert a rapid effect on search. These early cueing effects on reaction times were supported by evidence of guidance from cues on early eye movements. Experiment 2 introduced a feature to the cue that randomly matched the colour or orientation of the target. When cue orientation was predictive, there were strong implicit effects based on whether the colour of the cue and target matched. When cue colour was predictive, there were only weak effects from the cue's orientation. Implicit effects from cue colour remained when orientation-predictive cues were used and colour was unlikely to predict the target (Experiment 3). The data suggest that strong effects of colour cueing result from a combination of implicit and explicit processes, whereas effects from orientation cues are largely limited to the explicit guidance of visual search.  相似文献

We used a change blindness paradigm to examine the “other race” effect in perception. White Caucasian and Indian Asian participants viewed scenes in which White Caucasian and Indian Asian students were present. Changes were made either to the faces of the students, to their bodies or to an independent object in the background. Changes in faces were detected faster than changes in the bodies, which were in turn detected faster than changes in the background. For face detection there was a crossover interaction, with changes in White Caucasian faces detected faster than changes in Indian Asian faces by White Caucasian participants, whilst the opposite result occurred for changes in Indian Asian faces. In contrast, there was no effect of race on the detection of body-part changes or on the detection of changes to background objects. The results suggest that participants of both races attended equally well to subjects from the other race in the scene, but despite this they remained less sensitive to “other race” faces. Change blindness can provide a useful way of analysing attentional and memorial processes in social contexts.  相似文献

The tendency of GPs to cap the number of counselling sessions offered to their patients in primary care has led to an ongoing debate about the effectiveness of time-limited counselling and brief therapy models. the advantages and disadvantages of brief as opposed to open-ended models of counselling in primary care need to be considered from the point of view of the client, the counsellor and the GP. Given that outcome research shows no difference between the two methods, a cost-benefit analysis would indicate that, for the majority of cases, time-limited counselling works very well. But there is still a minority of clients who do need open-ended therapy, and their needs are not being served by the present NHS system. Counsellors should therefore not be debating for either brief or open-ended style in primary care, but should be organizing themselves into expanding the service to give GPs the choice of both approaches.  相似文献

Brain oscillations in various frequency bands have been shown to be an important means of enabling interarea communication for high-level cognitive performance. Interestingly, perturbation to such oscillations in the form of weak noise has been shown to benefit perception in tasks such as the attentional blink (AB). Here, we investigated perturbation intrinsic to the AB task in two conditions in which noise arose from either temporal or spatial discontinuity. Consistent with theoretical predictions, temporal discontinuity resulted in a reduced AB, whereas spatial discontinuity resulted in an increased AB. The results are discussed in the framework of both stochastic resonance theory and pretarget alpha oscillations, two neurally based accounts of perceptual processing.  相似文献

We present the case for a role of biologically plausible neural network modeling in bridging the gap between physiology and behavior. We argue that spiking-level networks can allow "vertical" translation between physiological properties of neural systems and emergent "whole-system" performance-enabling psychological results to be simulated from implemented networks and also inferences to be made from simulations concerning processing at a neural level. These models also emphasize particular factors (e.g., the dynamics of performance in relation to real-time neuronal processing) that are not highlighted in other approaches and that can be tested empirically. We illustrate our argument from neural-level models that select stimuli by biased competition. We show that a model with biased competition dynamics can simulate data ranging from physiological studies of single-cell activity (Study 1) to whole-system behavior in human visual search (Study 2), while also capturing effects at an intermediate level, including performance breakdown after neural lesion (Study 3) and data from brain imaging (Study 4). We also show that, at each level of analysis, novel predictions can be derived from the biologically plausible parameters adopted, which we proceed to test (Study 5). We argue that, at least for studying the dynamics of visual attention, the approach productively links single-cell to psychological data.  相似文献

We investigated the impact of ingroup/outgroup categorization on the encoding of same-race and other-race faces presented in inter-racial and intra-racial contexts (Experiments 1 and 2, respectively). White participants performed a same/different matching task on pairs of upright and inverted faces that were either same-race (White) or other-race (Black), and labeled as being from the same university or a different university. In Experiment 1, the same- and other-race faces were intermixed. For other-race faces, participants demonstrated greater configural processing following same- than other-university labeling. Same-race faces showed strong configural coding irrespective of the university labeling. In Experiment 2, faces were blocked by race. Participants demonstrated greater configural processing of same- than other-university faces, but now for both same- and other-race faces. These results demonstrate that other-race face processing is sensitive to non-racial ingroup/outgroup status regardless of racial context, but that the sensitivity of same-race face processing to the same cues depends on the racial context in which targets are encountered.  相似文献

Previous studies have shown that attention is drawn to the location of manipulable objects and is distributed across pairs of objects that are positioned for action. Here, we investigate whether central, action-related objects can cue attention to peripheral targets. Experiment 1 compared the effect of uninformative arrow and object cues on a letter discrimination task. Arrow cues led to spatial-cueing benefits across a range of stimulus onset asynchronies (SOAs: 0?ms, 120?ms, 400?ms), but object-cueing benefits were slow to build and were only significant at the 400-ms SOA. Similar results were found in Experiment 2, in which the targets were objects that could be either congruent or incongruent with the cue (e.g., screwdriver and screw versus screwdriver and glass). Cueing benefits were not influenced by the congruence between the cue and target, suggesting that the cueing effects reflected the action implied by the central object, not the interaction between the objects. For Experiment 3 participants decided whether the cue and target objects were related. Here, the interaction between congruent (but not incongruent) targets led to significant cueing/positioning benefits at all three SOAs. Reduced cueing benefits were obtained in all three experiments when the object cue did not portray a legitimate action (e.g., a bottle pointing towards an upper location, since a bottle cannot pour upwards), suggesting that it is the perceived action that is critical, rather than the structural properties of individual objects. The data suggest that affordance for action modulates the allocation of visual attention.  相似文献
