The authors investigated the effects of changes in horizontal viewing angle on visual and audiovisual speech recognition in 4 experiments, using a talker's face viewed full face, three quarters, and in profile. When only experimental items were shown (Experiments 1 and 2), identification of unimodal visual speech and visual speech influences on congruent and incongruent auditory speech were unaffected by viewing angle changes. However, when experimental items were intermingled with distractor items (Experiments 3 and 4), identification of unimodal visual speech decreased with profile views, whereas visual speech influences on congruent and incongruent auditory speech remained unaffected by viewing angle changes. These findings indicate that audiovisual speech recognition withstands substantial changes in horizontal viewing angle, but explicit identification of visual speech is less robust. Implications of this distinction for understanding the processes underlying visual and audiovisual speech recognition are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved) 相似文献

The authors investigated whether a Simon effect could be observed in an accessory-stimulus Simon task when participants were unaware of the task-irrelevant accessory cue. In Experiment 1A a central visual target was accompanied by a suprathreshold visual lateral cue. A regular Simon effect (i.e., faster cue-response corresponding reaction times [RTs]) was found. Experiment 1B demonstrated that this effect cannot be attributed to perceptual grouping of the target and cue. Experiments 2A, 2B, and 2C showed a reverse Simon effect (i.e., faster noncorresponding RTs) when participants were not aware of the cue. In this condition, the Simon effect would occur relative to the reorientation of attention from the cue, which would initially capture attention, toward the target. This conclusion is supported by the results of Experiments 3A and 3B, in which the reorientation of attention was induced by having the target flash after its onset. With suprathreshold cues either a reverse or regular Simon effect was observed by using a 100-ms or ≥200-ms onset flashing interval, respectively, whereas with subthreshold cues a reverse Simon effect was found irrespective of the interval length.

According to one approach to speech perception, listeners perceive speech by applying general pattern matching mechanisms to the acoustic signal (e.g., Diehl, Lotto, & Holt, 2004). An alternative is that listeners perceive the phonetic gestures that structured the acoustic signal (e.g., Fowler, 1986). The two accounts have offered different explanations for the phenomenon of compensation for coarticulation (CfC). An example of CfC is that if a speaker produces a gesture with a front place of articulation, it may be pulled slightly backwards if it follows a back place of articulation, and listeners' category boundaries shift (compensate) accordingly. The gestural account appeals to direct attunement to coarticulation to explain CfC, whereas the auditory account explains it by spectral contrast. In previous studies, spectral contrast and gestural consequences of coarticulation have been correlated, such that both accounts made identical predictions. We identify a liquid context in Tamil that disentangles contrast and coarticulation, such that the two accounts make different predictions. In a standard CfC task in Experiment 1, gestural coarticulation rather than spectral contrast determined the direction of CfC. Experiments 2, 3, and 4 demonstrated that tone analogues of the speech precursors failed to produce the same effects observed in Experiment 1, suggesting that simple spectral contrast cannot account for the findings of Experiment 1.

In the present experiment, the authors tested Mandarin and English listeners on a range of auditory tasks to investigate whether long-term linguistic experience influences the cognitive processing of nonspeech sounds. As expected, Mandarin listeners identified Mandarin tones significantly more accurately than English listeners; however, performance did not differ across the listener groups on a pitch discrimination task requiring fine-grained discrimination of simple nonspeech sounds. The crucial finding was that cross-language differences emerged on a nonspeech pitch contour identification task: The Mandarin listeners more often misidentified flat and falling pitch contours than the English listeners in a manner that could be related to specific features of the sound structure of Mandarin, which suggests that the effect of linguistic experience extends to nonspeech processing under certain stimulus and task conditions.

The authors describe a new visual illusion first discovered in a natural setting. A cyclist riding beside a pair of sagging chains that connect fence posts appears to move up and down with the chains. In this illusion, a static shape (the chains) affects the perception of a moving shape (the bicycle), and this influence involves assimilation (averaging) rather than opposition (differentiation). These features distinguish the illusion from illusions of motion capture and induced motion. The authors take this bicycle illusion into the laboratory and report 4 findings: Na?ve viewers experience the illusion when discriminating horizontal from sinusoidal motion of a disc in the context of stationary curved lines; the illusion shifts from motion assimilation to motion opposition as the visual size of the display is increased; the assimilation and opposition illusions are dissociated by variations in luminance contrast of the stationary lines and the moving disc; and the illusion does not occur when simply comparing two stationary objects at different locations along the curved lines. The bicycle illusion provides a unique opportunity for studying the interactions between shape and motion perception. (PsycINFO Database Record (c) 2010 APA, all rights reserved) 相似文献

The authors examined the effects of preferred music, visual distraction, and silence on pain perception. Visual distraction was provided by participants' choice of painting from a selection of 15 popular artworks. Eighty participants (43 females) underwent 3 trials of cold pressor pain induction with measurement of tolerance, pain intensity, perceived control, and anxiety, and a music listening patterns questionnaire. Preferred music was found to significantly increase tolerance and perceived control over the painful stimulus and to decrease anxiety compared with both the visual distraction and silence conditions. Pain intensity rating was decreased by music listening when compared with silence. During the music condition, frequent listening to the chosen piece in everyday life was found to negatively correlate with anxiety level, and extent of knowledge of the lyrics further positively correlated with tolerance of the stimulus and perceived control. That general importance of music in everyday life also correlated with perceived control reiterates the importance of relationship and familiarity with favorite music as key to its therapeutic effect. There was no relationship between structural features of the selected music and any of the significant effects. It is suggested that preference may render music with different structural aspects functionally equivalent. (PsycINFO Database Record (c) 2010 APA, all rights reserved) 相似文献

Rodents are able to rely on self-motion (idiothetic) cues and navigate toward a reference place by path integration. The authors tested the effects of dorsal hippocampal and parietal lesions in a homing task to dissociate the respective roles of the hippocampus and the parietal cortex in path integration. Hippocampal rats exhibited a strong deficit in learning the basic task. Parietal rats displayed a performance impairment as a function of the complexity of their outward paths when the food was placed at varying locations. These results suggest that the parietal cortex plays a specific role in path integration and in the processing of idiothetic information, whereas the hippocampus is involved in the calibration of space used by the path integration system.

A number of computational models have been developed over the last 2 decades that are remarkably successful at explaining the process of translating print into sound. Nevertheless, 2 of the most successful computational accounts on the table fail to simulate the results from factorial experiments reported in this article in which university students read aloud letter strings that varied in terms of spelling–sound regularity and lexicality (regular words vs. exception words vs. nonwords) and stimulus quality (bright vs. dim). Skilled readers yielded additive effects of regularity and stimulus quality and additive effects of lexicality and stimulus quality on both RT and errors when nonwords were mixed with words. When only words appeared in the list, there was an interaction in which exception words were less affected by low stimulus quality than regular words were; no existing account anticipates or explains these results. We advance a hypothesis that assumes a novel module that accommodates these data and provide an existence proof in the form of a simulation.

The joint effects of stimulus quality and word frequency in lexical decision were examined in 4 experiments as a function of nonword type (legal nonwords, e.g., BRONE, vs. pseudohomophones, e.g., BRANE). When familiarity was a viable dimension for word-nonword discrimination, as when legal nonwords were used, additive effects of stimulus quality and word frequency were observed in both means and distributional characteristics of the response-time distributions. In contrast, when the utility of familiarity was undermined by using pseudohomophones, additivity was observed in the means but not in distributional characteristics. Specifically, opposing interactive effects in the underlying distribution were observed, producing apparent additivity in means. These findings are consistent with the suggestion that, when familiarity is deemphasized in lexical decision, cascaded processing between letter and word levels is in play, whereas, when familiarity is a viable dimension for word-nonword discrimination, processing is discrete.

The psychometric properties of the newest version of the Temperament and Character Inventory (the TCI-R) were evaluated in a large (n = 727) community sample, as was the TCI-140, a short inventory derivative. Facets-to-scale confirmatory and exploratory factor analyses of the TCI-R did not support the organization of temperament and character facet scales within their superordinate domains. Five of the 29 facet scales also displayed relatively low internal consistency (α 相似文献

This study examined the factor structure of the parent and teacher versions of the Strengths and Difficulties Questionnaire (SDQ; R. Goodman, 1997) with a sample of first-grade children at risk for educational failure. The 5-factor model previously found in studies using exploratory factor analysis was fit to the data for both parent and teacher questionnaires. Fit indices for both versions were marginally adequate. Model fit was comparable across gender and ethnic groups. Factor fit for the parent questionnaire was invariant across parent educational level. The examination of convergent and discriminant validity included peer evaluations of each SDQ construct. Thus, each of the five constructs was evaluated by three sources (parent, teacher, and child). On the basis of D. T. Campbell and D. W. Fiske's (1959) multitrait-multimethod approach as well as a confirmatory factor analysis using the correlated uniqueness model, the SDQ has good convergent validity but relatively poor discriminant validity.

A modified version of the Revised Memory and Behavior Problems Checklist (RMBPC; L. Ten et al, 1992) was administered across 6 different sites to 1,229 family caregivers of community-dwelling adults with dementia. The total sample was divided randomly into 2 subsamples. Principal components analyses on occurrence responses and reaction ratings from the first subsample resulted in a 3-factor solution that closely resembled the originally proposed dimensions (memory-related problems, disruptive behaviors, and depression). Confirmatory factor analyses on data from the second subsample indicated adequate fit for the 3-factor model. Correlations with other caregiver and care-recipient measures supported the convergent and discriminant validity of the RMBPC measures. In addition, female caregivers and White caregivers reported more problems, on average, than male caregivers and African American caregivers, respectively.

Reports an error in Factor structure of the BASC–2 Behavioral and Emotional Screening System Student Form by E. Dowdy, et al. (Psychological Assessment. np). There was an omission in the author note. The author note should have included a disclosure as follows, “Randy W. Kamphaus wishes to disclose a potential conflict of interest in that he receives a portion of royalties on net sales of BESS.” (The following abstract of the original article appeared in record 2011-04578-001.) The BASC–2 Behavioral and Emotional Screening System (BESS) Student Form (Kamphaus & Reynolds, 2007) is a recently developed youth self-report rating scale designed to identify students at risk for behavioral and emotional problems. The BESS Student Form was derived from the Behavior Assessment System for Children—Second Edition Self-Report of Personality (BASC–2 SRP; Reynolds & Kamphaus, 2004) using principal component analytic procedures and theoretical considerations. Using 3 samples, the authors conducted exploratory factor analyses (EFA) and confirmatory factor analyses (CFA) to understand the underlying factor structure of the BESS Student Form. The results of the EFA suggested that the SRP contained a 4-factor (i.e., Personal Adjustment, Inattention/Hyperactivity, Internalizing, School Problems) emergent structure, which was supported by CFA in 2 additional samples. Practical and research implications are discussed. (PsycINFO Database Record (c) 2011 APA, all rights reserved) 相似文献

Multiracial Americans represent a rapidly growing population (Shih & Sanchez, 2009); however, very little is known about the types of challenges and resilience experienced by these individuals. To date, few psychological measures have been created specifically to investigate the experiences of multiracial people. This article describes 2 studies focused on the development and psychometric properties of the Multiracial Challenges and Resilience Scale (MCRS). The MCRS was developed using a nationwide Internet sample of urban, multiracial adults. Exploratory factor analyses revealed 4 Challenge factors (Others' Surprise and Disbelief Regarding Racial Heritage, Lack of Family Acceptance, Multiracial Discrimination, and Challenges With Racial Identity) and 2 Resilience factors (Appreciation of Human Differences and Multiracial Pride). A confirmatory factor analysis with data from a second sample provided support for the stability of this factor structure. The reliability and validity of the measure, implications of these findings, and suggestions for future research are discussed. (PsycINFO Database Record (c) 2011 APA, all rights reserved) 相似文献

In this article, we examined the factorial validity of the Dutch translation of the Children's Behavior Questionnaire (CBQ) and the Very Short Form scores. In addition, we conducted cross-cultural comparisons of temperament structure. In total, 353 parents of 6- to 8-year-olds completed the instrument. The original higher order factor structure of the different CBQ forms was generally replicated and represented the three broad dimensions of temperament: Surgency/Extraversion, Negative Affectivity, and Effortful Control. For the Standard Form, results demonstrated a relatively high degree of factor similarity of the Dutch sample with other cultures (e.g., China and Japan). The findings provide evidence for applicability of the CBQ in Western Europe as a promising instrument to comprehensively assess reactive and self-regulative temperamental dimensions in young children.

The Brief Psychiatric Rating Scale (BPRS) is the most commonly used outcome measure for the severely and persistently mentally ill (SPMI) population, possessing good interrater reliability, concurrent validity, and a strong factor structure. However, psychometric study of the extended version of the BPRS (the BPRS-E) is limited when compared with earlier versions (BPRS and BPRS-A). This study examined the item, factor, and diagnosis-specific sensitivity to change of the BPRS-E, the most recent version of this popular scale. Assessments were conducted at 90-day intervals with 201 adult psychiatric inpatients at the Utah State Hospital, yielding 786 symptom ratings. Of note was that ratings were conducted by independent assessors who were unaware of patients' treatment status. All but 2 of the 24 BPRS-E items, all 4 factors, and the total score were found to be sensitive to change when comparing patients' admission and discharge scores. Patient diagnosis was not associated with item, factor, or total score sensitivity to change. These findings extend the psychometric support for the BPRS-E and have implications for assessing outcome with the SPMI population. (PsycINFO Database Record (c) 2010 APA, all rights reserved) 相似文献

The Self-Awareness and Management Strategies (SAMS) Scales were created to assess therapists' experiences of hindering self-awareness during counseling sessions. A sample of 301 therapists completed the SAMS, along with 2 other measures used to establish validity. In addition to asking about therapists' experiences with their self-awareness, the SAMS also assessed the strategies therapists use to manage hindering self-awareness. The results suggest that there is strong initial evidence for the reliability and validity of the SAMS Scales. A factor analysis of the SAMS Scales resulted in 2 subscales for hindering self-awareness (Anxious and Distracting) and 5 subscales of management strategies (Self-Care, Relaxation, Focusing on the Client, Suppression, and Use of Basic Techniques). Future research ideas and implications for counseling are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved) 相似文献
