New genetic tests reveal risks for multiple conditions simultaneously, although little is understood about the psychological factors that affect testing uptake. We assessed a conceptual model called the multiplex genetic testing model (MGTM) using structural equation modelling. The MGTM delineates worry, perceived severity, perceived risk, response efficacy and attitudes towards testing as predictors of intentions and behaviour. Participants were 270 healthy insured adults aged 25–40 from the Multiplex Initiative conducted within a health care system in Detroit, MI, USA. Participants were offered a genetic test that assessed risk for eight common health conditions. Confirmatory factor analysis revealed that worry, perceived risk and severity clustered into two disease domains: cancer or metabolic conditions. Only perceived severity of metabolic conditions was correlated with general response efficacy (β?=?0.13, p<0.05), which predicted general attitudes towards testing (β?=?0.24, p<0.01). Consistent with our hypothesised model, attitudes towards testing were the strongest predictors of intentions to undergo testing (β?=?0.49, p<0.01), which in turn predicted testing uptake (OR 17.7, β?=?0.97, p<0.01). The MGTM explained a striking 48% of the variance in intentions and 94% of the variation in uptake. These findings support use of the MGTM to explain psychological predictors of testing for multiple health conditions.  相似文献

Quiet eye training—teaching task-specific gaze control—has been consistently shown to optimize the acquisition of motor skills. The present study aimed to examine the potential benefits of a quiet eye training intervention in a simulated maritime marksmanship task that involved shooting fast approaching moving targets with a decommissioned general-purpose machine gun. Twenty participants were randomly assigned to a quiet eye trained (QET) or technical trained (TT) group and completed 2 baseline, 20 training, and 2 retention trials on the moving-target task. Compared to their TT counterparts, the QET group displayed more effective gaze control (longer quiet eye durations and greater target locking) and more accurate performance (smaller radial error of both the initial shot and average of all shots) at retention. These findings highlight the potential for quiet eye training to be used to support the training of marksmanship skills in military settings.  相似文献

Across three experiments we sought to determine whether extrafoveally presented emotional faces are processed sufficiently rapidly to influence saccade programming. Two rectangular targets containing a neutral and an emotional face were presented either side of a central fixation cross. Participants made prosaccades towards an abrupt luminosity change to the border of one of the rectangles. The faces appeared 150 ms before or simultaneously with the cue. Saccades were faster towards cued rectangles containing emotional compared to neutral faces even when the rectangles were positioned 12 degrees from the fixation cross. When faces were inverted, the facilitative effect of emotion only emerged in the ?150 ms SOA condition, possibly reflecting a shift from configural to featural face processing. Together the results suggest that the human brain is highly specialized for processing emotional information and responds very rapidly to the brief presentation of expressive faces, even when these are located outside foveal vision.  相似文献

The present study uses relative weight analysis to garner support for the incremental validity of political skill over more traditional managerial skills for predicting managerial effectiveness and to help identify the underlying theoretical mechanisms driving this relationship. In addition, we explore boundary conditions, in terms of gender and organizational level, where political skill may be more or less critical. Using 199 middle- and upper-level managers enrolled in leadership development programmes and multisource data, the findings supported political skill’s incremental validity over more traditional measures of managerial skills for predicting managerial effectiveness. In addition, two of five political skill dimensions—image management and interpersonal influence—were significantly important predictors of managerial effectiveness, providing support for social influence theory as perhaps the best theoretical model for understanding the political skill-effectiveness relationship. Also, an individual’s gender and level in the organizational hierarchy had significant moderating effects on the relationship between three political skill dimensions and managerial effectiveness.  相似文献

When in the progression of Alzheimer’s disease (AD) a decline in detection sensitivity and recognition memory for odors begins, and whether a fast progression in dementia is related to a fast loss in odor sensitivity, was determined by studying 78 patients with probable AD, categorized as very mild, mild, or moderate in degree of dementia, and 78 controls. Taste and vision were studied for comparison. Whereas the earliest decline in odor sensitivity and visual memory was found in mild patients, a decline in odor memory was found in the very mild patients. Similar taste thresholds in the four groups suggest that the poor odor detectability in AD was not related to task demands in threshold testing. A fast progression in dementia was also found to be related to a fast loss in odor sensitivity. The findings imply that memory-based olfactory tests may contribute to early diagnosis of AD.  相似文献

Social learning is taxonomically widespread and can provide distinct behavioural advantages, such as in finding food or avoiding predators more efficiently. Although extensively studied in bony fishes, no such empirical evidence exists for cartilaginous fishes. Our aim in this study was to experimentally investigate the social learning capabilities of juvenile lemon sharks, Negaprion brevirostris. We designed a novel food task, where sharks were required to enter a start zone and subsequently make physical contact with a target in order to receive a food reward. Naive sharks were then able to interact with and observe (a) pre-trained sharks, that is, ‘demonstrators’, or (b) sharks with no previous experience, that is, ‘sham demonstrators’. On completion, observer sharks were then isolated and tested individually in a similar task. During the exposure phase observers paired with ‘demonstrator’ sharks performed a greater number of task-related behaviours and made significantly more transitions from the start zone to the target, than observers paired with ‘sham demonstrators’. When tested in isolation, observers previously paired with ‘demonstrator’ sharks completed a greater number of trials and made contact with the target significantly more often than observers previously paired with ‘sham demonstrators’. Such experience also tended to result in faster overall task performance. These results indicate that juvenile lemon sharks, like numerous other animals, are capable of using socially derived information to learn about novel features in their environment. The results likely have important implications for behavioural processes, ecotourism and fisheries.  相似文献

Many studies have shown that heavy TV viewers make social reality judgments more in line with televised reality. Shrum's (2001) heuristic model of cultivation effects predicted and found that biases in first-order cultivation judgments resemble heuristic processing. Systematic processing eliminated the effect. This study presents a series of computational simulations to examine whether a simple feed-forward neural network model exhibits learning behavior in accordance with Shrum's model. The data from the model are tested in contrast to data from human participants. Results closely fit human data. Simulations show that increased television exposure increases construct accessibility; television exemplars are not discounted when exhibiting the cultivation effect; and systematic processing reduces or eliminates the cultivation effect.  相似文献

Spirituality has been an influential force for many people. Although often ignored in business settings, it has recently been a topic of heightened interest to managers and scholars worldwide. In Bahia, Brazil, the fundamentals of spirituality for some have existed through Candomblé and have been an integral part of the community including the workplace. Candomblé encompasses a variety of African religious traditions established in Brazil during the nineteenth century. This study examines the positive influences of the Brazilian Candomblé on workers and business life in Bahia. Through qualitative analysis, it offers organisational insights and managerial reflections that can be adapted and used in workplaces worldwide.  相似文献

Abstract

The healing power of psychodynamically oriented therapy and training groups rests, to a large degree, upon the quality of the here and now interactions. For the work to be effective, the basic principles of analytic group work need to be followed, including the observance of no extra–group contact. Simply said, nothing leaves the room. This principle has both ethical and clinical implications. It is my premise that while some forms of outside contact between members are relatively benign, other types are not. Outside contact that is built into the fabric and context of the group may pose a risk, as may be the case where dual relationships exist between members. The impact of dual relationships between group members in the particular instance of analytic training institutes is the focus of this article. What happens to the transference in this context when members reveal too much of their personal lives to each other through dual relationships is explored. It is suggested that extra–group contact can disrupt the balance between reality and transference distortion in group interactions in at least three ways: (a) “The Emperor’s New Clothes” effect, (b) looping, and (c) gaslighting. Vignettes are presented to illustrate these phenomena and suggestions for reform are offered.  相似文献
