Bisection tasks are used in research on normal space and time perception and to assess the perceptual distortions accompanying neurological disorders. Several variants of the bisection task are used, which often yield inconsistent results, prompting the question of which variant is most dependable and which results are to be trusted. We addressed this question using theoretical and experimental approaches. Theoretical performance in bisection tasks is derived from a general model of psychophysical performance that includes sensory components and decisional processes. The model predicts how performance should differ across variants of the task, even when the sensory component is fixed. To test these predictions, data were collected in a within-subjects study with several variants of a spatial bisection task, including a two-response variant in which observers indicated whether a line was transected to the right or left of the midpoint, a three-response variant (which included the additional option to respond “midpoint”), and a paired-comparison variant of the three-response format. The data supported the model predictions, revealing that estimated bisection points were least dependable with the two-response variant, because this format confounds perceptual and decisional influences. Only the three-response paired-comparison format can separate out these influences. Implications for research in basic and clinical fields are discussed.  相似文献

Despite positing a multiplicative model of performance, 3 recent studies failed to find support for a theoretically meaningful interaction between cognitive ability and trait motivation in predicting performance. We suggest that it is important to consider that these studies used trait–motivation constructs that are general in nature, rather than context–specific. Yet, existing theory and research suggests that it may be beneficial to use trait–motivation constructs that are expressly contextual, especially when investigating a multiplicative performance model. This study, therefore, compared general versus context–specific achievement motivation as moderators of the relationship between cognitive ability and performance. The proposition that only context–specific achievement motivation should interact with cognitive ability in predicting performance was supported. Implications are discussed.  相似文献

A review of literatures thought to be relevant for understanding situational contributions to ability-performance relationships was conducted. The review suggested that only three sets of variables, incentive systems, job characteristics, and leadership style/management philosophy ("climates") have recieved research attention from an ability/situation vantage point. It was also shown that in both experimental and survey research these three factors can moderate ability-performance relationships. Because these same three sets of variables are also known to have main effects on average performance levels, an hypothesis is presented that when organizations establish work conditions which facilitate the display of task-relevant individual ability, then validity for ability measures, average performance levels, and general levels of satisfaction will all be high.  相似文献

Semi-sparse PCA     
Eldén  Lars  Trendafilov  Nickolay 《Psychometrika》2019,84(1):164-185

It is well known that the classical exploratory factor analysis (EFA) of data with more observations than variables has several types of indeterminacy. We study the factor indeterminacy and show some new aspects of this problem by considering EFA as a specific data matrix decomposition. We adopt a new approach to the EFA estimation and achieve a new characterization of the factor indeterminacy problem. A new alternative model is proposed, which gives determinate factors and can be seen as a semi-sparse principal component analysis (PCA). An alternating algorithm is developed, where in each step a Procrustes problem is solved. It is demonstrated that the new model/algorithm can act as a specific sparse PCA and as a low-rank-plus-sparse matrix decomposition. Numerical examples with several large data sets illustrate the versatility of the new model, and the performance and behaviour of its algorithmic implementation.

The present study examined the content and structure of self–reported motivation for Jewish religious behavior. Initial items were generated from comprehensive and detailed responses to a semi–structured interview and an open–ended questionnaire. Principal component factor analysis with orthogonal rotation was carried out on the responses of a sample of 323 research participants to two parallel sets of the 111 items produced by the above process. The factor structures for each of these sets of items were highly similar to each other and consisted of the following five reliable factors: belief in a divine order, ethnic identity, social activity, family activity, and upbringing. These factors appear to reflect the way religious behavior can contribute to the satisfaction of a number of general human motives. Persons with different religious identities were found to attribute their performance of religious ritual to different motives, providing a partial explanation for the apparent anomaly of the performance of religious ritual by persons who identify themselves as secular.  相似文献

It is held that specific ingredients are responsible for the effectiveness of various psychotherapies and it is supposed that for this reason particular therapeutic approaches are more efficient than others. First, this article presents Bruce E. Wampold’s research on psychotherapeutic efficacy, which gives evidence that psychotherapies efficiency is due to general, not to specific factors. It is shown that in the end the common factors like alliance, compliance, empathy and the fact, that therapists generally make best use of their personality, are interpersonal factors. The impact of these empirical results on psychotherapy, on theory and practice is described in the light of two metatheories, the “medical modell”and the “contextual model”. The author delineates some consequences, for instance that in psychotherapeutic practice the diagnosis-based indication for therapy has to be replaced by fitting-indication. Regarding outcome research, the randomized goldstandard research design has to be replaced by a fitting indication concerning therapist /patient and patient/paticular treatment. Further it is shown that although specific ingredients in a strict sense are not active, therapists have to realize that they are nessessary even if active only as a component of the healing context. How specific ingredients might be realized within a healing context is shown with regard to the adaptive approach to psychoanalysis.  相似文献

Quantitative research about academic cheating among Chinese college students is minimal. This paper discusses a large survey conducted in Chinese colleges and universities which examined the prevalence of different kinds of student cheating and explored factors that influence cheating behavior. A structural equation model was used to analyze the data. Results indicate that organizational deterrence and individual performance have a negative impact on cheating while individual perceived pressure, peers’ cheating, and extracurricular activities have a positive impact. Recommendations are proposed to reduce the level of academic cheating in China. Many of these are universal in nature and applicable outside of China as well.  相似文献

Many research fields concerned with the processing of information contained in human faces would benefit from face stimulus sets in which specific facial characteristics are systematically varied while other important picture characteristics are kept constant. Specifically, a face database in which displayed expressions, gaze direction, and head orientation are parametrically varied in a complete factorial design would be highly useful in many research domains. Furthermore, these stimuli should be standardised in several important, technical aspects. The present article presents the freely available Radboud Faces Database offering such a stimulus set, containing both Caucasian adult and children images. This face database is described both procedurally and in terms of content, and a validation study concerning its most important characteristics is presented. In the validation study, all frontal images were rated with respect to the shown facial expression, intensity of expression, clarity of expression, genuineness of expression, attractiveness, and valence. The results show very high recognition of the intended facial expressions.  相似文献

Interpersonal risk and resilience factors are prominent in current conceptual models of suicide. A growing body of empirical evidence links suicidal thoughts and behaviors to a range of interpersonal phenomenon adding further support to the value of this line of inquiry. At present, research on interpersonal phenomenon focuses on assessing individuals' perceptions of interpersonal phenomenon, such as appraisals of burdensomeness, experienced loneliness, and thwarted belongingness. As this line of research continues to develop, we argue that it would be valuable to consider incorporating conceptual models of interpersonal phenomenon and corresponding methodological approaches from closely allied fields. After providing a brief overview of interpersonal models of suicide, we present an introduction to conceptual models of interpersonal phenomenon developed in relationship science, describe how these models can be applied to the study of interpersonal phenomenon in suicide research, and close with a guided tutorial on data collection and statistical analysis methods for testing hypotheses derived from these conceptual approaches. References for additional reading are provided, and the Appendix S1 provides simulated data sets and statistical code for the analyses in the tutorial section.  相似文献

Community psychology (CP) research on the natural environment lacks a theoretical framework for analyzing the complex relationship between human systems and the natural world. We introduce other academic fields concerned with the interactions between humans and the natural environment, including environmental sociology and coupled human and natural systems. To demonstrate how the natural environment can be included within CP’s ecological framework, we propose an ecological model of urban forest stewardship action. Although ecological models of behavior in CP have previously modeled health behaviors, we argue that these frameworks are also applicable to actions that positively influence the natural environment. We chose the environmental action of urban forest stewardship because cities across the United States are planting millions of trees and increased citizen participation in urban tree planting and stewardship will be needed to sustain the benefits provided by urban trees. We used the framework of an ecological model of behavior to illustrate multiple levels of factors that may promote or hinder involvement in urban forest stewardship actions. The implications of our model for the development of multi-level ecological interventions to foster stewardship actions are discussed, as well as directions for future research to further test and refine the model.  相似文献

Although the connection between attention deficit hyperactivity disorder (ADHD) and developmental coordination disorder (DCD) has been recognized for several decades, little research has examined the relationship between these two disorders. This paper draws attention to the contribution the cognitive-energetic model (CEM) can make in determining the specific nature of these two disorders. An information processing approach such as the CEM is a useful model to identify specific and overlapping mechanisms that are disrupted in these two disorders. This paper describes the CEM and reviews the research so-far in relation to the model. The CEM has several advantages over other models: First, it predicts which task variables will be independent or may interact, thus enabling the investigator to determine the success/failure of the task manipulation(s) and identify spurious findings. Second, the CEM links energetic factors to task variables and predicts both additive and interactive effects. Third, the CEM enables executive processes such as selective attention, working memory and inhibition to be related to both energetic and lower level processes. Fourth, by employing the CEM in clinical research, taxonomy of deficits can be derived enabling further insight into the nature of the disorders and their specific neuropsychological dysfunction. Suggestions are made for future research into the neuropsychological deficits associated with ADHD and DCD.  相似文献

Individuals high in psychopathy are often portrayed as more likely to display antisocial behaviour in the workplace and to demonstrate lower job performance. Current research on the impact of trait psychopathy in the workplace is characterized by divergent findings of moderate versus weak effects. We aim to address two potential causes for these discrepant results: mono-source bias and the failure to consider the situational factors that can activate psychopathy. In addition, we used the triarchic model of psychopathy, which incorporates the meanness dimension, a conceptualization of predatory orientation. Our multi-source design disconfirmed concerns that the effects of psychopathy are merely based on mono-source bias. More specifically, we found that the predatory orientation of managers high in psychopathy and especially high in the trait of meanness was behaviourally activated by high levels of ascendency prospects and prospects for income increases. High psychopathy, mediated by consideration towards subordinates and moderated by high ascendency prospects and high prospects for income increases, was associated with low supervisory job performance ratings. Implications and limitations of our findings and directions for future research are discussed.  相似文献

Personality tests are often used in selection and have demonstrated predictive validity across a variety of occupational groups and performance criteria. Although different selection decision methods can be used to make selection decisions (e.g., compensatory top down, compensatory with sliding bands, noncompensatory) from personality test results, there is a paucity of research addressing the influence of these different selection decision methods on issues such as, adverse impact and differential hiring rates. This gap in the literature is redressed in the current study. Results from 398 bus operator candidates indicated that there may be adverse impact and differential hiring rate issues depending on the selection decision method used and the designated group being assessed. Implications and future research directions are discussed.  相似文献
