Early findings from Broca and Wernicke led to the classical view of hemispheric specialization, where the main idea relates to left-hemisphere language capabilities compared to right-hemisphere visual capabilities. Federmeier and Benjamin (2005) have suggested that semantic encoding for verbal information in the right hemisphere can be more effective when memory demands are higher. In light of this, our main goal was to study the effect of retention level of verbal information on hemispheric processes. However, regarding the cross-linguistic differences in orthography and their subsequent effects on word recognition (Frost, Katz, & Bentin, 1987), our intent was also to test prior predictions of Federmeier and Benjamin (2005) for a "shallow" orthography language, where words have a clear correspondence between graphemes and phonemes, as opposed to English, which is a "deep" orthography language. Portuguese concrete nouns were selected. The participants were submitted to a visual half-field word presentation using a continuous recognition memory paradigm. The retention level included 1, 2, 4, 8, 20 or 40 words. Results showed that recognition accuracy was higher for words studied in the right visual field, compared to those studied in the left visual field, when the retention interval included 2, 4, or 20 words. No significant differences were found for the remaining intervals. Further analysis on accuracy data for intermediate retention levels showed that recognition accuracy was higher for the 2 words retention level than for the levels including 4, 8, or 20 words; it was higher for left-hemisphere encoding as well. Our results also indicated that reaction times were slower for left-hemisphere encoding and for the 40 words retention level when compared to that of 20 words. In summary, the current results are in partial agreement with those of Federmeier and Benjamin (2005) and suggest different hemispheric memory strategies for the semantic encoding of verbal information. 相似文献

Alexithymia has been described as an important dimension in several medical and psychiatric diseases. Chronic urticaria (CU) is a chronic condition, in which treatment is difficult. Our aim is to determine the prevalence of alexithymia traits in patients with CU, and to identify the relationships between alexithymia and psychological variables and quality-of-life dimensions. Fifty-five sequential CU patients in a faculty ambulatory specialized consultation, with an average age of 44.92, were compared with 31 healthy volunteers. Both groups were studied by means of validated scales for alexithymia (Toronto Alexithymia Scale [TAS-20]), attachment (Adult Attachment Scale-R [AAS-R]), psychopathology (Brief Symptom Inventory [BSI]), personality dimensions (The NEO Five-Factor inventory [NEO-FFI]) and quality of life (Short Form-36 [SF-36]). The classification of CU reactions was obtained from the patient's history, physical examination, laboratory assessment and histopathologic findings. All the patients were under treatment with sedating H1-antihistamines, non-sedating H1-antihistamines combination of H1 and H2 blocker, 2 H1-antihistamines and 3 H1-antihistamines. High traits of alexithymia were found on CU patients (56.9%) as well as high symptom rates of anxiety. Alexithymia traits were significantly positively correlated with insecure attachment styles, with psychopathological symptoms, and with the defense mechanism turn against self. We also reported a significant negative correlation between alexithymia traits and the dimensions of quality of life. Insecure attachment styles were positively correlated with psychopathological symptoms and negatively correlated with quality of life. We did not find significant statistical correlations between alexithymia and clinical variables. CU patients present serious difficulty in dealing with emotion arousal. There is strong evidence of a psychosomatic specificity in CU, with marked alexithymic traits. 相似文献

Terror Management Theory posits that when individuals are faced with their own mortality, they use several defense mechanisms to reduce the existential anxiety caused by the thought of their own death. In this paper, we examined one such mechanism: Control attributions. To do so, we ran an experiment (n = 140) in which we manipulated mortality salience and type of failure (relevant vs. irrelevant consequences) with which participants were faced. Participants were then instructed to evaluate the possible causes of their failure. The results indicated that participants assigned to the mortality salience condition, compared to those assigned to the control group, were more prone to making controllable attributions. That is, even in situations in which individuals are motivated to avoid responsibility (i.e., a relevant failure), mortality salience increased perceived controllability. These results suggest that attributions might serve as a control mechanism to compensate for the sheer uncontrollability of death. 相似文献

While the most commonly employed burnout measure has been the Maslach Burnout Inventory (MBI), researchers have been troubled by some of the psychometric limitations of this instrument. The aim of this study was to analyze the psychometric properties of the "Spanish Burnout Inventory" (SBI). The psychometric properties were analysed with data from a sample of 277 Chilean professionals working to physical disabled people. The psychometric properties of the SBI were examined through the following analyses: confirmatory factor analysis, reliability Cronbach's alpha, and concurrent validity with the MBI. The hypothesized four factor model obtained an adequate data fit for the sample (chi2(164) = 285.32, p < .001, GFI = .96, RMSEA = .052, NNFI .93, CFI = .94). Results confirmed the hypothesis formulated. The Cronbach's alpha coefficient was higher than .70 for the four scales of the instruments. Results supported the concurrent validity with the MBI. As a whole, the results of these study provided evidence on the adequate psychometric properties of the SBI for the study of burnout in the Chilean cultural context. 相似文献

This paper presents a new corpus of 140 high quality colour images belonging to 14 subcategories and covering a range of naming difficulty. One hundred and six Spanish speakers named the items and provided data for several psycholinguistic variables: age of acquisition, familiarity, manipulability, name agreement, typicality and visual complexity. Furthermore, we also present lexical frequency data derived internet search hits. Apart from the large number of variables evaluated, these stimuli present an important advantage with respect to other comparable image corpora in so far as naming performance in healthy individuals is less prone to ceiling effect problems. Reliability and validity indexes showed that our items display similar psycholinguistic characteristics to those of other corpora. In sum, this set of ecologically valid stimuli provides a useful tool for scientists engaged in cognitive and neuroscience-based research. 相似文献

Vertebrates use geometric and featural information for spatial navigation. When both geometric and featural cues are available,
animals can use a variety of spatial strategies based on this information. To examine the nature of these strategies, we manipulated
the spatial relationship between a conspicuous cue and the position of the goal when goldfish (Carassius auratus) were searching
for the exit of a rectangular environment with one distinctive wall. Two groups of fish were used, one with the distinctive
wall close to the goal and the other with the distinctive wall on the other end of the enclosure. Results showed that fish
encoded featural and geometric information in both conditions but the spatial relationship between the goal and the distinctive
wall influences the characteristics of the encoding of the spatial cues and the strategy used to locate the goal. These results
suggest that fish in both procedures use the local featural cues associated with the goal instead of the whole set of spatial
cues as previous studies propose. 相似文献

The use of a visual analogue scale (VAS) for the assessment of stress during occupational health examination could be an useful tool. However, psychometrics features of the VAS have to be assessed. The aim of this study is to test the inter judge reliability of the VAS in a psychological dimension assessment. Two occupational physician have used the VAS in a worker group. There is no significant difference in the distribution of VAS values. This result supports the hypothesis of a satisfactory inter judge reliability of the VAS in stress measurement. 相似文献

The present study conducted a preliminary examination of the psychometric properties of a recently developed Portuguese translation of the Acceptance of Cosmetic Surgery Scale (ACSS; Henderson-King & Henderson-King, 2005). A total of 311 Brazilian adults completed the ACSS along with Portuguese translations of measures of actual-ideal body weight discrepancy, body appreciation, sociocultural attitudes toward appearance, and demographics. Results showed that the Portuguese ACSS reduced to a three-factor solution consisting of the Intrapersonal, Social, and Consider factors uncovered in the original work using the ACSS. Moreover, there were only small sex differences on these subscales. In addition, the Portuguese ACSS showed a good pattern of convergent validity. The availability of the Portuguese ACSS is expected to stimulate more in-depth, quantitative research on attitudes toward cosmetic surgery within the Brazilian context. 相似文献

Illusory conjunctions in the time domain are binding errors for features from stimuli presented sequentially but in the same spatial position. A similar experimental paradigm is employed for the attentional blink (AB), an impairment of performance for the second of two targets when it is presented 200–500 msec after the first target. The analysis of errors along the time course of the AB allows the testing of models of illusory conjunctions. In an experiment, observers identified one (control condition) or two (experimental condition) letters in a specified color, so that illusory conjunctions in each response could be linked to specific positions in the series. Two items in the target colors (red and white, embedded in distractors of different colors) were employed in four conditions defined according to whether both targets were in the same or different colors. Besides the U-shaped function for hits, the errors were analyzed by calculating several response parameters reflecting characteristics such as the average position of the responses or the attentional suppression during the blink. The several error parameters cluster in two time courses, as would be expected from prevailing models of the AB. Furthermore, the results match the predictions from Botella, Barriopedro, and Suero’s (Journal of Experimental Psychology: Human Perception and Performance, 27, 1452–1467, 2001) model for illusory conjunctions. 相似文献
