Determining how we use our body to support cognition represents an important part of understanding the embodied and embedded nature of cognition. In the present investigation, we pursue this question in the context of a common perceptual task. Specifically, we report a series of experiments investigating head tilt (i.e., external normalization) as a strategy in letter naming and reading stimuli that are upright or rotated. We demonstrate that the frequency of this natural behavior is modulated by the cost of stimulus rotation on performance. In addition, we demonstrate that external normalization can benefit performance. All of the results are consistent with the notion that external normalization represents a form of cognitive offloading and that effort is an important factor in the decision to adopt an internal or external strategy.  相似文献

Using a hierarchical personality model approach, the trait of competitiveness was investigated in 3 studies. The results revealed that competitiveness may be positively associated with consumer behaviors occurring in three contexts: (a) besting others directly in contests (e.g., playing sports), (b) besting others indirectly through vicarious experiences (e.g., observing sports as a fan or watching drama‐based movies), and (c) besting others via the conspicuous consumption of material goods (e.g., purchasing innovative electronic products).  相似文献

This paper presents a noncompensatory latent trait model, the multicomponent latent trait model for diagnosis (MLTM-D), for cognitive diagnosis. In MLTM-D, a hierarchical relationship between components and attributes is specified to be applicable to permit diagnosis at two levels. MLTM-D is a generalization of the multicomponent latent trait model (MLTM; Whitely in Psychometrika, 45:479–494, 1980; Embretson in Psychometrika, 49:175–186, 1984) to be applicable to measures of broad traits, such as achievement tests, in which component structure varies between items. Conditions for model identification are described and marginal maximum likelihood estimators are presented, along with simulation data to demonstrate parameter recovery. To illustrate how MLTM-D can be used for diagnosis, an application to a large-scale test of mathematics achievement is presented. An advantage of MLTM-D for diagnosis is that it may be more applicable to large-scale assessments with more heterogeneous items than are latent class models.  相似文献

Abstract

This paper supports the contention that the brain stores memories in the form of a central representation that is accessed by both physical preparation and execution and, more importantly, by motor imagery associated with this preparation and execution. Considerable evidence in support of shared central and vegetative structures suggests that sport psychologists should consider more closely aspects of the performer's responses to the physical skill when providing imagery interventions and not rely on “traditional,” more clinically orientated, methods of delivery. Many texts provide a schedule of factors and techniques for psychologists, athletes, and coaches to consider but with a limited theoretical explanation of why these factors are the crucial concerns. We, therefore, propose an evidence-based, 7-point checklist that includes: physical, environmental, task, timing, learning, emotional, and perspective elements of imagery delivery highlighting the minimum requirement areas in which sport psychologists should monitor the equivalence to the physical task in order to enhance the efficacy of their practice.  相似文献

ABSTRACT

The current study aims to further investigate earlier established advantages of an error mastery approach over an error aversion approach. The two main purposes of the study relate to (1) self-regulatory traits (i.e., goal orientation and action-state orientation) that may predict which error approach (mastery or aversion) is adopted, and (2) proximal, psychological processes (i.e., self-focused attention and failure attribution) that relate to adopted error approach. In the current study participants' goal orientation and action-state orientation were assessed, after which they worked on an error-prone task. Results show that learning goal orientation related to error mastery, while state orientation related to error aversion. Under a mastery approach, error occurrence did not result in cognitive resources “wasted” on self-consciousness. Rather, attention went to internal-unstable, thus controllable, improvement oriented causes of error. Participants that had adopted an aversion approach, in contrast, experienced heightened self-consciousness and attributed failure to internal-stable or external causes. These results imply that when working on an error-prone task, people should be stimulated to take on a mastery rather than an aversion approach towards errors.  相似文献

The diversity of sexual behaviors is driven by multiple determinants, including physiological, cultural, educational, and sociological factors. However, the definition of sexual behavior profiles has been barely addressed from a comprehensive point of view. We aimed to develop a multidisciplinary questionnaire for defining individual sexual behavior profiles. The questionnaire was developed by a panel of experts with research experience in the fields of urology, gynecology, psychology, anthropology, and sexology. The list of items was defined in a focus group session and was based on four categories—family-oriented, loving, recreational, and functional—resulting from the combination of two axes: traditional versus non-traditional and sexual benefit versus extra-sexual benefit. Real-time Delphi dynamics was used to assign a weight to each question and a bias to the corresponding responses. The final questionnaire included 50 items considered relevant for describing sexual profiles; the final questionnaire was named SEX360. Of the 50 items included in SEX360, 14 were considered essential for computing the final score; 9 of them were associated with 2 categories, 4 of them with 4 categories, and 1 of them with 3. Nine items referred to the category “family-oriented”, 10 to “loving”, 8 to “recreational”, and 9 to “functional”. The weights assigned to each question ranged from 3.00 to 4.33, and the centers of gravity ranged from 1 to 4. The questionnaire proposed shows the existence of a vast diversity of sexual behavior profiles and may serve as a tool for sexual behavior research.  相似文献

A developmental framework emphasizing the combined impact of correlated constraints within and without the individual was applied to a prospective longitudinal study of early parenthood. The purpose was to use a person-approach to the analysis of longitudinal data to clarify risk for early parenthood and to generate hypotheses about potentially useful intervention strategies. Respondents were 475 youth who were assessed annually from seventh grade through the end of high school and, again, at ages 20 and 24. The risk patterns associated with parenthood were the same for both sexes. Individuals with a middle-school configuration of low socioeconomic status, high aggression, low academic skills, low popularity, and prior grade failure were most likely to become parents by early adulthood. Risk for early parenthood increased substantially for respondents who dropped out of school early, regardless of their initial risk status.  相似文献

Research studies in psychology and education often seek to detect changes or growth in an outcome over a duration of time. This research provides a solution to those interested in estimating latent traits from psychological measures that rely on human raters. Rater effects potentially degrade the quality of scores in constructed response and performance assessments. We develop an extension of the hierarchical rater model (HRM), which yields estimates of latent traits that have been corrected for individual rater bias and variability, for ratings that come from longitudinal designs. The parameterization, called the longitudinal HRM (L-HRM), includes an autoregressive time series process to permit serial dependence between latent traits at adjacent timepoints, as well as a parameter for overall growth. We evaluate and demonstrate the feasibility and performance of the L-HRM using simulation studies. Parameter recovery results reveal predictable amounts and patterns of bias and error for most parameters across conditions. An application to ratings from a study of character strength demonstrates the model. We discuss limitations and future research directions to improve the L-HRM.  相似文献

Multinomial processing tree models are widely used in many areas of psychology. Their application relies on the assumption of parameter homogeneity, that is, on the assumption that participants do not differ in their parameter values. Tests for parameter homogeneity are proposed that can be routinely used as part of multinomial model analyses to defend the assumption. If parameter homogeneity is found to be violated, a new family of models, termed latent-class multinomial processing tree models, can be applied that accommodates parameter heterogeneity and correlated parameters, yet preserves most of the advantages of the traditional multinomial method. Estimation, goodness-of-fit tests, and tests of other hypotheses of interest are considered for the new family of models. The author thanks Bill Batchelder, Edgar Erdfelder, Thorsten Meiser, and Christoph Stahl for helpful comments on a previous version of this paper. The author is also grateful to Edgar Erdfelder for making available the data set analyzed in this paper.  相似文献

Multinomial processing tree models are widely used in many areas of psychology. A hierarchical extension of the model class is proposed, using a multivariate normal distribution of person-level parameters with the mean and covariance matrix to be estimated from the data. The hierarchical model allows one to take variability between persons into account and to assess parameter correlations. The model is estimated using Bayesian methods with weakly informative hyperprior distribution and a Gibbs sampler based on two steps of data augmentation. Estimation, model checks, and hypotheses tests are discussed. The new method is illustrated using a real data set, and its performance is evaluated in a simulation study.  相似文献

A general linear latent trait model for continuous item responses is described. The special unidimensional case for continuous item responses is Joreskog's (1971) model of congeneric item responses. In the context of the unidimensional case model for continuous item responses the concepts of item and test information functions, specific objectivity, item bias, and reliability are discussed; also the application of the model to test construction is shown. Finally, the correspondence with latent trait theory for dichotomous item responses is discussed.  相似文献

While positive emotion can be conceptualized broadly as a response to the potential for reward, the environment offers different kinds of rewards, and these are best approached in somewhat different ways. A functional approach to positive emotion differentiation distinguishes among several different types of rewards with strong implications for adaptive fitness and posits the existence of “discrete” positive emotions that promote an adaptive response to each reward. A taxonomy of eight positive emotions, dubbed the “PANACEAS” taxonomy based on an acronym of the first letter of each of the eight constructs, is presented as an example of this approach. Positive emotion constructs defined through functional analyses are useful for guiding empirical research, especially for identifying prototypical eliciting stimuli, and generating hypotheses about the implications of different positive emotions for a variety of outcomes. Research findings are reviewed that support the importance of positive emotion differentiation in understanding the effects of positive emotions on cognition, physiology, and behavior. Advantages of the functional approach are discussed, as well as implications of the approach for evaluating major theories of the structure of emotion.  相似文献

This paper presents a qualitative and quantitative review of the antecedents of counterproductive behaviors (CPB). The qualitative review organizes antecedents identified in past research into four broad categories: personal, organizational, work, and contextual factors. The quantitative review includes metaanalyses of 40 published studies with a combined sample size of 42,359. The results indicate that employees who are young or dissatisfied engage in more CPBs. In addition, absenteeism is more prevalent among employees who are young, female, have lower income, have lower job satisfaction, and who perceive a stronger absence norm, or a stronger ability to be on time.  相似文献
