The goal of this study was to test the effect of mental workload on handwriting behavior and to identify characteristics of low versus high mental workload in handwriting. We hypothesized differences between handwriting under three different load conditions and tried to establish a profile that integrated these indicators. Fifty-six participants wrote three numerical progressions of varying difficulty on a digitizer attached to a computer so that we could evaluate their handwriting behavior. Differences were found in temporal, spatial, and angular velocity handwriting measures, but no significant differences were found for pressure measures. Using data reduction, we identified three clusters of handwriting, two of which differentiated well according to the three mental workload conditions. We concluded that handwriting behavior is affected by mental workload and that each measure provides distinct information, so that they present a comprehensive indicator of mental workload. 相似文献

We investigated the interaction between morphological structure and transposed-letter priming using the same-different task with Hebrew, a Semitic language in which morphology has been shown to play a key role in visual word recognition. In contrast to the results observed with lexical decision (e.g., Velan & Frost, 2009, 2011), a transposed-letter priming effect was observed irrespective of the morphological structure of the words. We take these results to suggest that morphological decomposition occurs only in the service of lexical access. We discuss further a unique feature of written Arabic, another Semitic language, to explain the apparent conflict between our findings and those reported by Perea, Abu Mallouh, García-Orza, and Carreiras (2010). 相似文献

Postoperative patients received one of the three, alternative pain-management treatments: patient-controlled analgesia (PCA); perceived PCA (PPCA without actual control) and continuous intravenous infusion of analgesics (CII). Pain reports, morphine consumption and satisfaction of the groups were compared, and influences of individual differences in preferences for control and trait anxiety were tested. The main findings were: (1) PCA patients consumed less morphine and reported more pain and somewhat higher satisfaction; (2) PPCA patients were intermediate between the other two groups in pain reports and morphine consumption and lowest in satisfaction and (3) individual differences did not moderate the effects of PCA. The findings were interpreted as indicating that the main effect of PCA is increased pain tolerance, and that a bio-psycho-social framework is most appropriate to explain these effects. 相似文献

ResumenEn este trabajo, tras una breve introducción en la que se considera la naturaleza e importancia de la escritura, se exponen las ideas generales sobre el estudio de su desarrollo, tanto desde un punto de vista histórico como ontogenético. Seguidamente, se propone una clasificación de los campos de estudio psicológico de la escritura. Por último, se expone un posible marco integrador del área de estudio de la escritura desde un punto de vista cognitivo. 相似文献

An emotion-based lengthening effect on the perception of durations of emotional pictures has been assumed to result from an arousal-based mechanism, involving the activation of an internal clock system. The aim of this study was to systematically examine the arousal effect on time perception when different discrete emotions were considered. The participants were asked to verbally estimate the duration of emotional pictures from the International Affective Picture System (IAPS). The pictures varied either in arousal level, i.e., high/low-arousal, for the same discrete emotion (disgust or sadness) or in the depicted emotion, e.g., disgust/fear for pictures matched for arousal (high-arousal). The results systematically revealed a lengthening effect on the perception of the duration of the emotional compared to the neutral pictures and indicated that the magnitude of this effect increased with arousal level. Nevertheless, variations in time perception were observed for one and the same arousal level, with the duration of disgust-inducing pictures (e.g., body mutilation) being judged longer than that of fear-inducing pictures (e.g., snake). These results suggest that arousal is a fundamental mechanism mediating the effect of emotion on time perception. However, the effect cannot be reduced to arousal, since the impact of the content of pictures also plays a critical role. 相似文献

Abstract Two possible motives for sensation seeking behavior, escape from self-awareness and compensatory self-regulation, were investigated in two studies. In Study I a questionnaire was developed to identify the putative escape and compensation motives suspected to contribute to sensation seeking behaviors. In Study II the factor structure of this new measure, called the Risk and Excitement Inventory (REI), was cross-validated using confirmatory factor analysis, and construct validity was examined. Together these studies suggest that the REI comprises two reliable factors, compensation and escape from self-awareness. Study II showed that these factors have a reasonable degree of construct validity. Limits of the measure and the model are discussed, and suggestions are offered for future research. 相似文献

During emerging adulthood, one’s sense of well-being undergoes many rapid changes. Although emerging adults often present considerable energy, creativity, and hopefulness, both in higher education classrooms and workplaces, they often experience a decrease in well-being due to experience confusion, stress encounters, and difficulties in transitioning to adulthood. The authors examined four noteworthy key socioemotional factors that may be linked to emerging adults' sense of well-being: career aspiration, self-esteem, body esteem, and gender. Three hundred 20- to 29-year-old university students participated in the study. Results showed that well-being was correlated positively with self-esteem and body esteem, and body esteem was correlated negatively with gender (men scored higher). Regression analyses revealed that for both men and women, self-esteem and body esteem predicted well-being. Nevertheless, when the gender was analyzed separately, career aspiration predicted well-being only for men, whereas body esteem predicted well-being only for women. The study findings illuminates the importance of generating preventive measures in childhood and adolescence, through reinforcing skills such as resilience and self-esteem with the aim of passing through emerging adulthood with as little harm as possible to the sense of well-being. 相似文献

The heterogeneity of schizophrenia remains an obstacle for understanding its pathophysiology. Studies using a tone discrimination screening test to classify patients have found evidence for 2 subgroups having either a specific deficit in verbal working memory (WM) or deficits in both verbal and nonverbal memory. This study aimed to (a) replicate in larger samples differences between these subgroups in auditory verbal WM; (b) evaluate their performance on tests of explicit memory and sustained attention; (c) determine the relation of verbal WM deficits to auditory hallucinations and other symptoms; and (d) examine medication effects. The verbal WM and tone discrimination performance did not differ between medicated (n = 45) and unmedicated (n = 38) patients. Patients with schizophrenia who passed the tone screening test (discriminators; n = 60) were compared with those who did not (nondiscriminators; n = 23) and healthy controls (n = 47). The discriminator subgroup showed poorer verbal WM than did controls and a deficit in verbal but not visual memory on the Wechsler Memory Scale-Revised (Wechsler, 1987), whereas the nondiscriminator subgroup showed overall poorer performance on both verbal and nonverbal tests and a marked deficit in sustained attention. Verbal WM deficits in discriminators were correlated with auditory hallucinations but not with negative symptoms. The results are consistent with a verbal memory deficit in a subgroup of schizophrenia having intact auditory perception, which may stem from dysfunction of language-related cortical regions, and a more generalized cognitive deficit in a subgroup having auditory perceptual and attentional dysfunction. 相似文献

The goals of this study were to examine the development of affective and behavioral changes following exposure to traumatic events among Israeli students studying under a high level of terror event exposure and to assess the effects of religiosity on those changes development. A questionnaire was administered to 770 students in the Ariel University Center in Judea and Samaria. Higher levels of terror exposure were associated with higher levels of avoidance behavior, subjective feelings of insecurity, and emotional distress. Higher religiosity moderated avoidance behavior, even when controlling for the level of objective exposure to terror events exposure, but had no influence on subjective sense of insecurity, or the level of emotional distress. These findings suggest that religiosity moderates behavioral changes development after traumatic event exposure mainly by reducing avoidance behavior. 相似文献

A central goal of modern generative grammar has been to discover invariant properties of human languages that reflect "the innate schematism of mind that is applied to the data of experience" and that "might reasonably be attributed to the organism itself as its contribution to the task of the acquisition of knowledge" (Chomsky, 1971). Candidates for such invariances include the structure dependence of grammatical rules, and in particular, certain constraints on question formation. Various "poverty of stimulus" (POS) arguments suggest that these invariances reflect an innate human endowment, as opposed to common experience: Such experience warrants selection of the grammars acquired only if humans assume, a priori, that selectable grammars respect substantive constraints. Recently, several researchers have tried to rebut these POS arguments. In response, we illustrate why POS arguments remain an important source of support for appeal to a priori structure-dependent constraints on the grammars that humans naturally acquire. 相似文献
