Two divided visual field lexical decision experiments were conducted to examine the role of the cerebral hemispheres in orthographic neighborhood effects. In Experiment 1, we employed two types of words: words with many substitution neighbors (high-N) and words with few substitution neighbors (low-N). Results showed a facilitative effect of N in the left visual field (i.e., right hemisphere) and an inhibitory effect of N in the right visual field (left hemisphere). In Experiment 2, we examined whether the inhibitory effect of the higher frequency neighbors increases in the left hemisphere as compared to the right hemisphere. To go beyond the usual N-metrics, we selected words with (or without) higher frequency neighbors (addition, deletion, or transposition neighbors). Results showed that the inhibitory effect of neighborhood frequency is enhanced in the right visual field. We examine the implications of these findings for the orthographic coding schemes employed by the models of visual word recognition. 相似文献

Letter identities and number identities are usually thought to imply different cortical mechanisms. Specifically, the left fusiform gyrus responds more to letters than to digits (T. A. Polk et al., 2002). However, a widely circulated statement on the internet illustrates that it is possible to use numbers (leet digits) as parts of words, 4ND TH3 R35ULT1NG S3NT3NC3 C4N B3 R34D W1TH0UT GR34T 3FF0RT. Two masked priming lexical decision experiments were conducted to determine whether leet digits produce (automatic) lexical activation. Results showed that words are identified substantially faster when they are preceded by a masked leet word (M4T3R14L-MATERIAL) than when they are preceded by a control condition with other letters or digits. In addition, there was only a negligible advantage of the identity condition over the related leet condition. This leet-priming effect is not specific to numbers: A prime in which leet digits are replaced by letter-like symbols (M(Delta symbol)T(euro symbol)R!(Delta symbol)L - MATERIAL) facilitates word processing to the same degree as an identity prime. Therefore, the cognitive system regularizes the shape of the leet digits and letter-like symbols embedded in words with very little cost. 相似文献

Although a lot of research has been developed during the last century in the field of human work design, the results seem to be unsatisfactory. Nowadays, there is renewed interest in this field but it is not producing any new results. This is the main reason why, in our investigation, we have tried to determine the real variables that truly affect the human work design. We have carried out two empirical researches involving 660 and 310 companies, obtaining from both exactly the same results, four factors that confirm the conclusions reached in previous research: demand-adaptation, flexibility-polyvalence, improvement-autonomy and conciliation-participation. We can add that these factors are independent from the environment and the type of technology used by the companies, which does not occur if the size of the enterprise is taken into account. 相似文献

The cross cultural equivalence of child (n = 217) and parent (n = 283) versions of the revised children’s manifest anxiety scale (RCMAS), multidimensional anxiety scale for children (MASC),
and the fear survey schedule for children—revised (FSSC-R) was examined in Mexican youth in Mexico, and Hispanic and white
European American youth in the USA. The RCMAS, MASC, and FSSC-R showed cross ethnic measurement equivalence. The Mexican and
Hispanic youth reported more worries, and the Mexican youth reported more somatic symptoms than the European American youth.
Per mother report, Mexican and Hispanic youth express more somatic symptoms than European American youth who also show the
least number of fears of the unknown and fears of danger and death. The results support the validity of commonly used child
anxiety measures with these populations and accrue evidence for greater anxiety and fear expression by Hispanic and Mexican
youth in certain domains.

The development of language indicating the emergence of thinking about the thoughts of self and others has been scarcely studied in Spanish-speaking children. For this reason, we studied the development of mental state language and various indicators of language development in 25 Spanish-speaking children assessed at 3, 3 1/2, 4, 4 1/2, and 5 years of age. We coded and categorized the 40,250 utterances children produced during the five time points, 1202 (3.01%) of which had mental terms. In this sample, mental state language in Spanish children developed with a similar timeline and patterns as described in English-speaking children. However, several findings were novel for studies of mental state language. The general indexes of syntactic development did not correlate with the production of mental terms. The Index of Lexical Diversity was associated with the frequency of references to verbs of desire. The results of regression analyses suggest that not only the development of subordinate sentences with complement is associated with genuine mental references to desires and beliefs, but the development of lexical skills as well. 相似文献

The main aim of this study was to explore the extent to which the number of associates of a word (NoA) influences lexical access, in four tasks that focus on different processes of visual word recognition: lexical decision, reading aloud, progressive demasking, and online sentence reading. Results consistently showed that words with a dense associative neighborhood (high-NoA words) were processed faster than words with a sparse neighborhood (low-NoA words), extending previous findings from English lexical decision and categorization experiments. These results are interpreted in terms of the higher degree of semantic richness of high-NoA words as compared with low-NoA words. 2008 Psychonomic Society, Inc. Author Note 相似文献

OBJECTIVE: To experimentally test the hypothesis that people who repeatedly participate in forms of non-violent crime exhibit an executive deficit detected in tests of high ecological validity, having changes in prefrontal functioning as neurophysiologic basis. PARTICIPANTS AND METHODS: A batteiy to assess executive dysfunction was administered--the Behavioural Assessment of the Dysexecutive Syndrome (BADS)--to an experimental group of 30 inmates convicted of crimes against property (mean age = 39.3, SD = 9.98), and a control group of 30 (mean age = 32.7, SD = 11.8), all male. RESULTS: The group of recurrent inmates performed significantly worse than the control group in their global scores on the battery, as well as in the majority of subscales. CONCLUSION: Without removing from consideration the fact that sample size was not very large and, primarily, alerting ourselves to the dangerous hypothesis of a "frontal criminogenesis," the authors interpret criminal recurrence and resistance to penal measures in terms of the scarcity of control that individuals from the experimental group have over their behavior and its respective consequences. 相似文献

This study investigated whether stimulus affective content can be extracted from visual scenes when these appear in parafoveal
locations of the visual field and are foveally masked, and whether there is lateralization involved. Parafoveal prime pleasant
or unpleasant scenes were presented for 150 msec 2.5° away from fixation and were followed by a foveal probe scene that was
either congruent or incongruent in emotional valence with the prime. Participants responded whether the probe was emotionally
positive or negative. Affective priming was demonstrated by shorter response latencies for congruent than for incongruent
prime-probe pairs. This effect occurred when the prime was presented in the left visual field at a 300-msec prime-probe stimulus
onset asynchrony, even when the prime and the probe were different in physical appearance and semantic category. This result
reveals that the affective significance of emotional stimuli can be assessed early through covert attention mechanisms, in
the absence of overt eye fixations on the stimuli, and suggests that right-hemisphere dominance is involved. 相似文献

Personality and behavioural assessment are common practice in research and applications throughout the world. Most of this research has been in English-speaking countries. Relatively little work has been done in cross-cultural settings to study the nature of response scale. Familiarity with an 11-point response scale in European countries may affect the reliability of questionnaire responses. In Spain, with mainly European MBA students, results show that an 11-point scale provides composites with greater reliability, validity and less invalidity, than the commonly used 5-point scale. 相似文献
