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

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

Three theoretical perspectives on cultural universals and differences in the content of self-concepts were tested in individualistic (United States, n = 178; Australia, n = 112) and collectivistic (Mexico, n = 157; Philippines, n = 138) cultures, using three methods of self-concept assessment. Support was found for both trait perspectives and the individual–self-primacy hypothesis. In contrast, support for cultural psychology hypotheses was limited because traits and other personal attributes were not more salient, or social attributes less salient, in individualistic cultures than collectivistic cultures. The salience of some aspects of self-concept depended on the method of assessment, calling into question conclusions based on monomethod studies. 相似文献

The author studies the intersubjective links which the pervert maintains with analyst or partner, attempting to indicate the differences between the investments in each case. Rather than accepting that empathy towards these patients is impossible to achieve and disturbs the countertransference profoundly, it attempts to show that these difficulties may be overcome if they are reinterpreted in the light of the theory of the intersubjective link. The author examines the theories and the practice of intersubjectivity and gives a definition of his approach to the link between two subjects. He applies these ideas to the case of a sexually masochistic female patient. The countertransference is marked successively by indifference, rejection and smothering. The analysis of the analyst's dream allows the situation to evolve. Failures in primary identification can result in domination over others and utilitarianism. The author examines the place of the challenge to the ‘Law’ and the father (in the attempt by the patient to put a theory to the test) in order to identify the figure of the witness in the pervert's intersubjective links. The desire of the transference would be marked by the figure of the witness rather than by that of the analyst as accomplice. 相似文献

Contemporary research on interpersonal influence has shown that individuals scoring high in Need for Cognition (NC) are able to generate a large number of arguments in order to convince other people. However, research has also shown that such an effort does not necessarily lead them to be more persuasive or more efficient in their group performance. The present research analysed this state of affairs, replicating and extending previous research by showing that appropriate training in socio-emotional group dimensions can increase group performance for individuals high in NC. Potential underlying mechanisms for such an effect are discussed. 相似文献

During the last decade, a considerable amount of evidence has accumulated to show that oxytocin (OT) is involved with functions other than its classical roles in reproduction-associated processes, such as social recognition, maternal behavior and neuroendocrine regulation of the stress response. It has been shown, for instance, that post-training systemic administration of oxytocin in mice produces an amnestic effect on the step-through inhibitory avoidance. Since it is still unclear how systemic levels of OT may affect CNS memory processes, our aim here was to investigate the hypothesis that systemic OT effects on memory retrieval might be mediated through an oxytocin-induced decrease in glucocorticoid release. In our first experiment, we have found an amnestic effect of i.p. pre-test 0.4 microg/kg of OT upon memory retrieval in the inhibitory avoidance task (IA); this OT dose was shown to (a) significantly decrease plasma corticosterone levels when compared to the saline group, and (b) not to cause any anxiety effects by itself in a plus-maze task. At last, an ineffective-by-itself dose of dexamethasone was able to reverse the amnestic effect of this OT dose. Our results suggest that the amnestic effect of systemically administered oxytocin upon memory retrieval in the inhibitory avoidance task was probably caused by an oxytocin-induced decrease in glucocorticoid release from the adrenal gland. 相似文献

Shannon entropy is being increasingly used in biomedical research as an index of complexity and information content in sequences of symbols, e.g. languages, amino acid sequences, DNA methylation patterns and animal vocalizations. Yet, distributional properties of information entropy as a random variable have seldom been the object of study, leading to researchers mainly using linear models or simulation-based analytical approach to assess differences in information content, when entropy is measured repeatedly in different experimental conditions. Here a method to perform inference on entropy in such conditions is proposed. Building on results coming from studies in the field of Bayesian entropy estimation, a symmetric Dirichlet-multinomial regression model, able to deal efficiently with the issue of mean entropy estimation, is formulated. Through a simulation study the model is shown to outperform linear modeling in a vast range of scenarios and to have promising statistical properties. As a practical example, the method is applied to a data set coming from a real experiment on animal communication. 相似文献

Cognitive behavioral therapy (CBT) has a strong evidence base for several psychiatric disorders, however, it may be argued that currently there is no overall agreement on what counts as ‘CBT’. One reason is that CBT is commonly perceived as encompassing a broad range of treatments, from purely cognitive to purely behavioral, making it difficult to arrive at a clear definition. The purpose of the present study was to explore practicing therapists’ perceptions of CBT. Three hundred fifty members of two multi-disciplinary interest groups for CBT in Sweden participated. Mean age was 46 years, 68% were females, 63% psychologists and mean number of years of professional experience was 12 years. Participants completed a web-based survey including items covering various aspects of CBT practice. Overall, therapist perceptions of the extent to which different treatment techniques and procedures were consistent with CBT were in line with current evidence-based CBT protocols and practice guidelines, as were therapists’ application of the techniques and procedures in their own practice. A majority of participants (78%) agreed that quality of life or level of functioning were the most important outcome measures for evaluating treatment success. Eighty percent of therapists believed that training in CBT at a basic level was a requirement for practicing CBT. There was a medium size Spearman correlation of rs=.46 between the perceived importance of research to practice and the extent to which participants kept themselves updated on research. Implications for training, quality assurance, and the effectiveness of CBT in clinical practice are discussed. 相似文献

Shift of the cortical mechanisms of language from the usually dominant left to the non-dominant right hemisphere has been demonstrated in the presence of large brain lesions. Here, we report a similar phenomenon in a patient with a cavernoma over the anterolateral superior temporal gyrus associated with epilepsy. Language mapping was performed by two complementary procedures, magnetoencephalography, and electrocorticography. The maps, indicated right temporal lobe dominance for receptive language and left frontal lobe dominance for expressive language. These results indicate that a small lesion, associated with epilepsy, may produce selective shifting of receptive language mechanisms as large lesions have been known to produce. 相似文献
