This study tested the psychometric characteristics of the Body Morph Assessment version 2.0 (BMA 2.0). A sample of 563 adults composed of four groups classified by gender and ethnicity (Caucasian men and women and African-American men and women) were studied. Support for the internal consistency and test–retest reliability of the BMA 2.0 was found for both men and women. A study of convergent validity was conducted. The BMA 2.0 was found to have adequate reliability and validity. Norms were established for the BMA 2.0 estimates of current body size (CBS), ideal body size (IBS), and acceptable body size (ABS) for Caucasian and African-American men and women. In summary, the BMA 2.0 is a reliable and valid computerized measure of CBS, IBS, ABS, the CBS–IBS discrepancy (body dissatisfaction), and provides an estimate of over/underestimation of body size as compared to individuals of the same sex and body mass index.  相似文献

A widely agreed-upon feature of spoken word recognition is that multiple lexical candidates in memory are simultaneously activated in parallel when a listener hears a word, and that those candidates compete for recognition (Luce, Goldinger, Auer, & Vitevitch, Perception 62:615–625, 2000; Luce & Pisoni, Ear and Hearing 19:1–36, 1998; McClelland & Elman, Cognitive Psychology 18:1–86, 1986). Because the presence of those competitors influences word recognition, much research has sought to quantify the processes of lexical competition. Metrics that quantify lexical competition continuously are more effective predictors of auditory and visual (lipread) spoken word recognition than are the categorical metrics traditionally used (Feld & Sommers, Speech Communication 53:220–228, 2011; Strand & Sommers, Journal of the Acoustical Society of America 130:1663–1672, 2011). A limitation of the continuous metrics is that they are somewhat computationally cumbersome and require access to existing speech databases. This article describes the Phi-square Lexical Competition Database (Phi-Lex): an online, searchable database that provides access to multiple metrics of auditory and visual (lipread) lexical competition for English words, available at www.juliastrand.com/phi-lex.  相似文献

This study addresses the issue of cognitive slowing in the elderly by examining the time course of automatic lexical access. College-aged subjects typically show a brief rise time (300-500 msec) for lexical access. In the present study, we examine whether there are changes in rapid, automatized access routines with age. Elderly and college-aged subjects performed a lexical decision task wherein semantically related words embedded in a continuous list were presented one at a time with a varying (300-1500 msec) inter-word interval. The use of a continuous list, a repeated word, and a very short inter-stimulus interval allowed automatic lexical access to be straightforwardly examined. The elderly subjects showed an onset of automatic lexical access that was similar in time frame to that for college-age subjects. These findings suggest that wherever the locus of age-related slowing may be, it is not in the early, language-specific processing devices that mediate lexical access.  相似文献

This study introduces the Sentiment Analysis and Cognition Engine (SEANCE), a freely available text analysis tool that is easy to use, works on most operating systems (Windows, Mac, Linux), is housed on a user’s hard drive (as compared to being accessed via an Internet interface), allows for batch processing of text files, includes negation and part-of-speech (POS) features, and reports on thousands of lexical categories and 20 component scores related to sentiment, social cognition, and social order. In the study, we validated SEANCE by investigating whether its indices and related component scores can be used to classify positive and negative reviews in two well-known sentiment analysis test corpora. We contrasted the results of SEANCE with those from Linguistic Inquiry and Word Count (LIWC), a similar tool that is popular in sentiment analysis, but is pay-to-use and does not include negation or POS features. The results demonstrated that both the SEANCE indices and component scores outperformed LIWC on the categorization tasks.  相似文献

Understanding the feasibility of using KEYS to assess the organizational climate for creativity in non‐Western societies is essential for researchers studying cultural influences on workers' perceptions of workplace climates. This study reports on the effectiveness of translating KEYS, using data from 401 employees of 13 different companies in Taiwan. A confirmatory factor analysis was performed and its results indicated a satisfactory fit for a 10‐factor model. However, six items tackling environmental obstacles had low factor loadings (<0.3) and should either be eliminated or amended. The results raise questions regarding the role of cultural influences in international studies that assess creativity climates. Further research into the conceptualization of organizational creativity in Chinese societies is warranted.  相似文献

Identification and discrimination of lexical tones in Cantonese were compared in the context of a traditional categorical perception paradigm. Three lexical tone continua were used: one ranging from low level to high level, one from high rising to high level, and one from low falling to high rising. Identification data showed steep slopes at category boundaries, suggesting that lexical tones are perceived categorically. In contrast, discrimination curves generally showed much weaker evidence for categorical perception. Subsequent investigation showed that the presence of a tonal context played a strong role in the identification of target tones and less of a role in discrimination. The results are consistent with the hypothesis that tonal category boundaries are determined by a combination of regions of natural auditory sensitivity and the influence of linguistic experience.  相似文献

This study investigated the reliability and validity of the Norwegian version of the Automatic Thoughts Questionnaire. Three samples were used: (a) 344 male military recruits; (b) 142 psychiatric outpatients; and (c) 41 healthy controls. The Automatic Thoughts Questionnaire was found to have high internal consistency and satisfactory temporal stability. It correlated positively with the Beck Depression Inventory and was found to discriminate significantly between clinically depressed and non-depressed psychiatric patients and healthy controls. In general the results are satisfactory, suggesting that the Norwegian version of the Automatic Thoughts Questionnaire has adequate reliability and validity properties. The Automatic Thoughts Questionnaire was shown to be a useful measure of frequency of automatic negative thoughts in both clinical and non-clinical populations.  相似文献

This paper explores the psychometric properties of the Bulgarian version of the OSI. It was found that most of the OSI scales were applicable in a Bulgarian context. In addition, the validity of the OSI Type A scale was confirmed using Jenkin’s Type A questionaire. Further work is needed however if the OSI is to be an appropriate instrument in other Eastern countries.  相似文献

A new computer software tool for coding and analyzing verbal report data is described. Combining and extending the capabilities of earlier verbal report coding software tools, CAPAS 2.0 enables researchers to code two different types of verbal report data: (1) verbal reports already transcribed and stored in text files and (2) verbal reports in their original digitally recorded audio format. For both types of data, individual verbal report segments are presented in random order and coded independently of other segments in accordance with a localized encoding principle. Once all reports are coded, CAPAS 2.0 converts the coded reports to a formatted file suitable for analysis by statistical packages such as SPSS. R. J. Crutcher, crutcher@udayton.edu  相似文献

Electric Vehicles (EVs) are propagated as an essential solution for reducing the carbon footprint of traffic activities. One essential barrier to the adoption of electromobility strategies in everyday life is the very limited driving range of typical EVs. A dense and reliable network of electric charging stations would enable safer and longer ranges. Modern fast-charging technologies provide additional possibilities to tactically and quickly re-charge EVs, but high implementation costs make it necessary to establish a mixed infrastructure consisting of cheap-but-slow and expensive-but-fast charging stations. We utilized the so-called Safe-Range-Inventory (SRI), a multidimensional assessment tool for capturing multi-facets of subjective range safety assessments. Using scenarios with different infrastructure settings, we revealed that the addition of just one fast-charging option drastically lowers range anxiety even under relatively short emergency range conditions. Additional fast-charging options did not have strong positive effects on the assessments but would amass very high costs. The SRI can assist in the planning of electric charging infrastructures in order to find the right balance between range safety and installation and maintenance costs.  相似文献

ObjectivesThe purpose of this research was to develop the Sport Commitment Questionnaire-2 (SCQ-2) and establish its psychometric properties. The SCQ-2 measures the updated Sport Commitment Model (SCM: Scanlan, Russell, Scanlan, Klunchoo, & Chow, 2013) and replaces the outdated Sport Commitment Questionnaire (SCQ) that assessed the original SCM (Scanlan, Simons, Carpenter, Schmidt, & Keeler, 1993).DesignBased on prior commitment research, items were generated to refine and expand the original SCQ subscales and to measure new candidate constructs to the SCM. A multiphase study was then conducted.MethodsPhase 1 participants were 753 male/female adolescent athletes (ages 13–19 years) from six sports representing varying levels of task interdependence. Using similar methodology as Phase 1, Phase 2 assessed 982 male/female adolescent athletes.ResultsExploratory factor analysis of Phase 1 data revealed 13 factors: two types of commitment (Enthusiastic and Constrained) and 11 sources. Confirmatory factor analysis of Phase 2 data supported a 58-item, 12-factor structure. In addition, all subscales were internally consistent. Structural equation modeling revealed that the sources explained 81.8% of the variance in Enthusiastic Commitment and 63.9% in Constrained Commitment.ConclusionsThe SCQ-2 assesses the sources and types of commitment in the updated SCM. Based on several indices of fit and the composite reliabilities, psychometric support for the SCQ-2 was established.  相似文献

In this study, we introduce pause detection (PD) as a new tool for studying the on-line integration of lexical and semantic information during speech comprehension. When listeners were asked to detect 200-ms pauses inserted into the last words of spoken sentences, their detection latencies were influenced by the lexical-semantic information provided by the sentences. Listeners took longer to detect a pause when it was inserted within a word that had multiple potential endings, rather than a unique ending, in the context of the sentence. An event-related potential (ERP) variant of the PD procedure revealed brain correlates of pauses as early as 101 to 125 ms following pause onset and patterns of lexical-semantic integration that mirrored those obtained with PD within 160 ms of pause onset. Thus, both the behavioral and the electrophysiological responses to pauses suggest that lexical and semantic processes are highly interactive and that their integration occurs rapidly during speech comprehension.  相似文献

Based on Lazarus and Folkman's 1984 Stress-Coping Model, a self-report measure for children between 8 and 12 years of age was constructed. It is called the Stress and Coping Questionnaire for Children (School version and Asthma version) and measures children's emotional responses and coping strategies when they confront school-related and asthma-related stressors. The factor structure of this questionnaire was assessed and cross-validated in two samples, one of 392 primary school children without a chronic disease and one of 119 children with asthma. Five scales of coping strategies with regard to two school-related stressors and one asthma-related stressor were distinguished in a reliable way, Approach, Avoidance, Seeking Social Support, Aggression, and Crying.  相似文献

In this article, we present Procura-PALavras (P-PAL), a Web-based interface for a new European Portuguese (EP) lexical database. Based on a contemporary printed corpus of over 227 million words, P-PAL provides a broad range of word attributes and statistics, including several measures of word frequency (e.g., raw counts, per-million word frequency, logarithmic Zipf scale), morpho-syntactic information (e.g., parts of speech [PoSs], grammatical gender and number, dominant PoS, and frequency and relative frequency of the dominant PoS), as well as several lexical and sublexical orthographic (e.g., number of letters; consonant–vowel orthographic structure; density and frequency of orthographic neighbors; orthographic Levenshtein distance; orthographic uniqueness point; orthographic syllabification; and trigram, bigram, and letter type and token frequencies), and phonological measures (e.g., pronunciation, number of phonemes, stress, density and frequency of phonological neighbors, transposed and phonographic neighbors, syllabification, and biphone and phone type and token frequencies) for ~53,000 lemmatized and ~208,000 nonlemmatized EP word forms. To obtain these metrics, researchers can choose between two word queries in the application: (i) analyze words previously selected for specific attributes and/or lexical and sublexical characteristics, or (ii) generate word lists that meet word requirements defined by the user in the menu of analyses. For the measures it provides and the flexibility it allows, P-PAL will be a key resource to support research in all cognitive areas that use EP verbal stimuli. P-PAL is freely available at http://p-pal.di.uminho.pt/tools.  相似文献

The need to study the positive aspects of body image led to the design of the Body Appreciation Scale (BAS). The aim of the present study was to develop a Spanish adaptation of the BAS for adolescents, testing its factor structure, construct validity and any differences between girls and boys. Participants were 312 adolescents aged between 12 and 20; there were 148 females and 164 males. The validation analysis of the BAS revealed a one-factor structure with adequate internal consistency (Cronbach's alpha = .908) and construct validity (correlations with body mass index, influence of the body shape model, perceived stress, coping strategies, self-esteem and variables from the Eating Disorders Inventory-2), as well as significant differences between boys and girls (p < .01). The BAS is suitable for administration in a Spanish adolescent population as a way of analysing the positive aspects of body image.  相似文献

Several studies show that parental knowledge about child development and education is relevant to parenting actions. Considering that the lack of assessment instruments specific to this domain in Portugal is an obstacle to cross-cultural research and programme evaluation, the objective of this study was to make available a Portuguese version of the Knowledge of Infant Development Inventory-P (KIDI-P). This inventory (58 items) allows for the calculation of three summary scores (Attempted, Accuracy and Total) that reflect correctness and confidence in one's knowledge. The Portuguese version of the KIDI-P confirmed a unidimensional structure and revealed good internal consistency (α = .89). In a sample of 252 mothers and fathers, educational level showed to be related to KIDI-P scores, unlike parents’ sex and age.  相似文献

In two lexical decision experiments, the present study was designed to examine emotional valence effects on visual lexical decision (standard and go/no-go) performance, using traditional analyses of means and distributional analyses of response times. Consistent with an earlier study by Kousta, Vinson, and Vigliocco (Cognition 112:473–481, 2009), we found that emotional words (both negative and positive) were responded to faster than neutral words. Finer-grained distributional analyses further revealed that the facilitation afforded by valence was reflected by a combination of distributional shifting and an increase in the slow tail of the distribution. This suggests that emotional valence effects in lexical decision are unlikely to be entirely mediated by early, preconscious processes, which are associated with pure distributional shifting. Instead, our results suggest a dissociation between early preconscious processes and a later, more task-specific effect that is driven by feedback from semantically rich representations.  相似文献

J. S. Adelman and G. D. A. Brown (2008) provided an extensive analysis of the form of word frequency and contextual diversity effects on lexical decision time. In this reply, the current authors suggest that their analysis provides a valuable tool for the evaluation of models of lexical access and that the results they report are broadly supportive of the rank hypothesis suggested by W. S. Murray and K. I. Forster (2004)--more supportive, in fact, than the originally reported data. However, Adelman and Brown's conclusion that the results of these analyses can be taken as evidence against rank (and thereby serial models of lexical access) and for instance models is rejected. It is shown that at least one instance model makes the wrong predictions and that Adelman and Brown's conclusions rest on the assumption that lexical decision time presents a pure measure of the time involved in lexical access. Results from eye tracking are reported, which also support a rank account, as do results from analyses that show that a log frequency account is clearly inadequate. Finally, it is demonstrated that, unlike other models, the rank account continues to make accurate predictions regarding the form of both reaction time and error rate effects.  相似文献

This study reports the validation of the Hong Kong version of Oxford Cognitive Screen (HK-OCS). Seventy Cantonese-speaking healthy individuals participated to establish normative data and 46 chronic stroke survivors were assessed using the HK-OCS, Albert’s Test of Visual Neglect, short test of gestural production, and Hong Kong version of the following assessments: Western Aphasia Battery, MMSE, MoCA, Modified Barthel Index, and Lawton Instrumental Activities of Daily Living scale. The validity of the HK-OCS was appraised by the difference between the two participant groups. Neurologically unimpaired individuals performed significantly better than stroke survivors on the HK-OCS. Positive and significant correlations found between cognitive subtests in the HK-OCS and related assessments indicated good concurrent validity. Excellent intra-rater and inter-rater reliabilities, fair test–retest reliability, and acceptable internal consistency suggested that the HK-OCS had good reliability. Specific HK-OCS subtests including semantics, episodic memory, number writing, and orientation were the best predictors of functional outcomes.  相似文献
