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

Participants often respond more quickly and more accurately to a repeated stimulus compared to a non-repeated one, a phenomenon known as repetition priming. In semantic classification tasks priming appears to be largely attributable to the learning of stimulus-decision and stimulus-response associations, which allow participants to bypass many of the processes engaged during initial stimulus analysis. The current study tested whether stimulus-response learning plays a similarly dominant role in priming that occurs in perceptual classification tasks. Unfamiliar objects were used as stimuli to reduce the influence of semantic processes on priming and the task switched for all test trials to eliminate stimulus-decision learning. The results showed across-task priming as measured by reaction time facilitation and improved accuracy when the response remained the same during the encoding and test phases. When the response switched, similar levels of reaction time facilitation were observed, but priming as measured by accuracy was significantly reduced and no longer significant. These findings indicate that stimulus-response learning contributes to priming in perceptual classification tasks, but does not play a dominant role. Significant stimulus-level learning that is independent of the task and response also occurs and likely indexes facilitated perceptual processing of the objects. 相似文献

A large body of research has focused on how people exchange and use information during the negotiation process. This work tends to treat information as if it all were readily available upon request. The current research investigated how delays in the pursuit of missing information can influence people’s ex-ante priorities and the final settlements they reach. Study 1 found that negotiators achieved more value on an issue after seeking missing information about that issue compared to when the same information was readily accessible. Study 2 found that the effect of searching for information on outcomes was mediated by changes in how important negotiators perceived the issue to be. Theoretical and practical implications are discussed. 相似文献

Efforts to find missing or wanted individuals have been characterized as an example of event‐based prospective memory called prospective person memory. We examined prospective person memory in the context of missing children. Participants studied 4 or 12 mock missing child posters. In Experiment 1, we equated total time per poster and found no difference between conditions in prospective person memory accuracy. In Experiment 2, we equated total time for all posters and found evidence of a decrease in prospective person memory accuracy in the 12‐poster condition. In Experiment 3, we allowed free study and also found a decrease in prospective person memory accuracy. Across all three experiments, we also found evidence of a more liberal response bias in the 12‐poster condition. Results are discussed in terms of both practical and theoretical implications.

Personal reputation has been argued to demonstrate important influences on work outcomes. However, substantive research on personal reputation is relatively scarce. This two‐study investigation empirically supports and extends existing theory regarding the temporal development of personal reputation (i.e., antecedents and consequences), and thus contributes to a more informed understanding of both the construct and criterion‐related validity of this important construct. Study 1 is conducted longitudinally, in order to assess the development of personal reputation over time, which is undertaken to demonstrate the effects of human capital and social effectiveness as antecedents of reputation. Study 2 complements and extends the first study by conducting a field investigation examining the effects of time, human capital, and social effectiveness as antecedents of personal reputation, while also exploring the reputation consequences of autonomy, power, and career success. Our findings suggest that human capital, time, and social effectiveness play a part in the development of a reputation. Furthermore, career success, power, and autonomy were shown to be outcomes of the reputation construct. Contributions and strengths of this investigation, limitations, and directions for future research are discussed. 相似文献

The pipeline toward careers in science, technology, engineering, and mathematics (STEM) begins to leak in high school, when some students choose not to take advanced mathematics and science courses. We conducted a field experiment testing whether a theory-based intervention that was designed to help parents convey the importance of mathematics and science courses to their high school-aged children would lead them to take more mathematics and science courses in high school. The three-part intervention consisted of two brochures mailed to parents and a Web site, all highlighting the usefulness of STEM courses. This relatively simple intervention led students whose parents were in the experimental group to take, on average, nearly one semester more of science and mathematics in the last 2 years of high school, compared with the control group. Parents are an untapped resource for increasing STEM motivation in adolescents, and the results demonstrate that motivational theory can be applied to this important pipeline problem. 相似文献

Change blindness is the inability to detect changes that occur in a scene, when the scene is briefly obscured while the change happens. It has been found to occur during driving simulations and computer use for example. Scene-Complexity, stimulus On-Time and time for which a scene is obscured can all affect our ability to detect changes (or change blindness). In most studies parameters have been selected to induce change blindness with little consideration of the extent to which change blindness might be induced. There is however evidence that variables that describe the visual scene can affect likelihood of detecting changes (Rensink Visual Cognition 7:345?C376, 2000). These effects have in this paper been explored in combination. Increasing Scene-Complexity, decreasing stimulus On-Time and increasing the duration for which a scene is obscured all increase change blindness but they all interact to further increase the likelihood of changes being missed. In order to reduce change blindness in a changing scene, all the variables need to be considered. 相似文献

It is known that properties of words such as their imageability can influence our ability to remember those words. However, it is not known if other object-related properties can also influence our memory. In this study we asked whether a word representing a concrete object that can be functionally interacted with (i.e., high-manipulability word) would enhance the memory representations for that item compared to a word representing a less manipulable object (i.e., low-manipulability word). Here participants incidentally encoded high-manipulability (e.g., CAMERA) and low-manipulability words (e.g., TABLE) while making word judgments. Using a between-subjects design, we varied the depth-of-processing involved in the word judgment task: participants judged the words based on personal experience (deep/elaborative processing), word length (shallow), or functionality (intermediate). Participants were able to remember high-manipulability words better than low-manipulability words in both the personal experience and word length groups; thus presenting the first evidence that manipulability can influence memory. However, we observed better memory for low- than high-manipulability words in the functionality group. We explain this surprising interaction between manipulability and memory as being mediated by automatic vs. controlled motor-related cognition. 相似文献

Despite some principal similarities, there is no systematic comparison between the different types of synesthesia (genuine, acquired and drug-induced). This comprehensive review compares the three principal types of synesthesia and focuses on their phenomenological features and their relation to different etiological models. Implications of this comparison for the validity of the different etiological models are discussed. Comparison of the three forms of synesthesia show many more differences than similarities. This is in contrast to their representation in the literature, where they are discussed in many respects as being virtually similar. Noteworthy is the much broader spectrum and intensity with the typical drug-induced synesthesias compared to genuine and acquired synesthesias. A major implication of the phenomenological comparison in regard to the etiological models is that genuine and acquired synesthesias point to morphological substrates, while drug-induced synesthesia appears to be based on functional changes of brain activity. 相似文献

We are constantly exposed to our own face and voice, and we identify our own faces and voices as familiar. However, the influence
of self-identity upon self-speech perception is still uncertain. Speech perception is a synthesis of both auditory and visual
inputs; although we hear our own voice when we speak, we rarely see the dynamic movements of our own face. If visual speech
and identity are processed independently, no processing advantage would obtain in viewing one’s own highly familiar face.
In the present experiment, the relative contributions of facial and vocal inputs to speech perception were evaluated with
an audiovisual illusion. Our results indicate that auditory self-speech conveys a processing advantage, whereas visual self-speech
does not. The data thereby support a model of visual speech as dynamic movement processed separately from speaker recognition. 相似文献
