We studied the time course of material categorization in natural images relative to superordinate and basic-level object categorization, using a backward-masking paradigm. We manipulated several low-level features of the images—including luminance, contrast, and color—to assess their potential contributions. The results showed that the speed of material categorization was roughly comparable to the speed of basic-level object categorization, but slower than that of superordinate object categorization. The performance seemed to be crucially mediated by low-level factors, with color leading to a solid increase in performance for material categorization. At longer presentation durations, material categorization was less accurate than both types of object categorization. Taken together, our results show that material categorization can be as fast as basic-level object categorization, but is less accurate. 相似文献

The aim of the present study was to contribute to the literature on the ability to recognize anger, happiness, fear, surprise, sadness, disgust, and neutral emotions from facial information (whole face, eye region, mouth region). More specifically, the aim was to investigate older adults' performance in emotions recognition using the same tool used in the previous studies on children and adults’ performance and verify if the pattern of emotions recognition show differences compared with the other two groups. Results showed that happiness is among the easiest emotions to recognize while the disgust is always among the most difficult emotions to recognize for older adults. The findings seem to indicate that is more easily recognizing emotions when pictures represent the whole face; compared with the specific region (eye and mouth regions), older participants seems to recognize more easily emotions when the mouth region is presented. In general, the results of the study did not detect a decay in the ability to recognize emotions from the face, eyes, or mouth. The performance of the old adults is statistically worse than the other two groups in only a few cases: in anger and disgust recognition from the whole face; in anger recognition from the eye region; and in disgust, fear, and neutral emotion recognition from mouth region. 相似文献

As a general rule, adolescents suffering from severe organic diseases experience more difficulty than adults and children in recognizing the illness and undergoing treatment, because there is a conflict between accepting the sick body and the sexual body. Dependence on medical treatment, moreover, clashes with the normal drive to autonomy. Long experience as a consultant psychiatrist in the haematology department of a hospital enables the author to propose a hypothesis as to the emotional significance of Hodgkin's disease and chemotherapy, concentrating particular attention on the refusal reaction to the chemotherapy itself. The psychoanalytical psychotherapy of a female adolescent suffering from Hodgkin's disease is presented and discussed to illustrate the theoretical and technical implications. 相似文献

Despite evidence that exists about the severity of impact of child sexual abuse (CSA), less has been published about treatment options. Much CSA is enshrouded in secrecy in the context of dysfunctional family dynamics, therefore group work is often recommended as a method of treatment. Although long- and short-term groups are seen as being equally effective, there are few published studies of long-term analytic groups for survivors of CSA. This study was designed to analyse the process of one long-term group. A case is made for using Core Conflictual Relationship Theme (CCRT), a method designed to analyse individual therapy, with reference to group theory. Shifts in self-perception and in relation to others are analysed from the beginning to the end of therapy. 相似文献

Subitizing, the rapid, effortless, and accurate enumeration of small numbers of items has been said to be carried out preattentively. If so, the preattentive processing could occur entirely in primary visual cortex, in which case it would be completed within about 50 ms, or during the feedforward sweep, in which case it would be completed within about 100 ms after the onset of an enumeration display which was followed by a mask. The stimulus–mask SOAs were 50 or 83 ms in Experiment 1, and 100 or 150 ms in Experiment 2. In both experiments subjects were more accurate and more sensitive to one-target than to two-target displays. These outcomes, in conjunction with the finding that accuracy and sensitivity were higher at the longer SOA, are inconsistent with the preattentive viewpoint and point to the necessity for attentional involvement in subitizing. 相似文献

In conflicts between social groups, the decision of competitors whether to attack/retreat should be based on the assessment
of the quantity of individuals in their own and the opposing group. Experimental studies on numerical cognition in animals
suggest that they may represent both large and small numbers as noisy mental magnitudes subject to scalar variability, and
small numbers (≤4) also as discrete object-files. Consequently, discriminating between large quantities, but not between smaller
ones, should become easier as the asymmetry between quantities increases. Here, we tested these hypotheses by recording naturally
occurring conflicts in a population of free-ranging dogs, Canis lupus familiaris, living in a suburban environment. The overall probability of at least one pack member approaching opponents aggressively
increased with a decreasing ratio of the number of rivals to that of companions. Moreover, the probability that more than
half of the pack members withdrew from a conflict increased when this ratio increased. The skill of dogs in correctly assessing
relative group size appeared to improve with increasing the asymmetry in size when at least one pack comprised more than four
individuals, and appeared affected to a lesser extent by group size asymmetries when dogs had to compare only small numbers.
These results provide the first indications that a representation of quantity based on noisy mental magnitudes may be involved
in the assessment of opponents in intergroup conflicts and leave open the possibility that an additional, more precise mechanism
may operate with small numbers. 相似文献

Individual differences in child temperament are associated with individual differences in language development. The present study examined the relationship between temperament and language ability in 109 twenty-four- to 30-month-old children. Parents and day-care teachers completed two questionnaires: the Primo Vocabolario del Bambino (Caselli & Casadio, 1995) and the Questionari Italiani del Temperamento (Axia, 2002). Researchers administered the First Language Test (Axia, 1993) to assess productive and receptive language in each child. Replicating previous research (Usai, Garello, & Viterbori, 2009), day-care teachers identified three temperamental profiles: most of the children fit into the first profile, typical of the Italian population; another profile was made up of easily distractible and not very persistent children, with a poor capacity to modulate motor activity; and the third profile of children were inhibited in new situations. A relationship was found between temperament assessed by day-care teachers and different levels of linguistic competence. In particular, the groups of "inattentive" and "inhibited" children showed poorer lexical and morphological abilities and a more immature vocabulary, characterised by the presence of more primitive components of the lexical repertory compared to the group of "typical" children. Unlike the results from day-care teachers, temperament questionnaires completed by parents revealed a 4-cluster-solution. Also, for parents, the "typical" profile is characterised by the largest vocabulary (productive and receptive) and the most mature semantic production. 相似文献

Conclusion In this paper, I have demonstrated that Føllesdal's famous interpretation of Husserl's concept of the noema is mistaken due to a fundamental misunderstanding of Husserlian terminology. I have given what I consider to be a correct explanation of the notion of the noema and of Husserlian terminology and have backed my claims with direct references to the text. I have then compared and contrasted these with Føllesdal's interpretation and, thereby, have explained the nature of his mistakes with regards to terminology. I have also shown that two of Føllesdal's faithful followers, Smith and McIntyre, have walked a similarly erroneous path with regards to their interpretation of Husserl's theory of meaning in theIdeas.I do not know where the key to the reconciliation of phenomenology and analytic philosophy lies. But, I do know that it does not lie in the claim that Husserl shared Frege's view on the nature of meaning as an abstract intensionalSinn nor does it lie in the related view that Husserl radically changed his conception of the relation of meanings to intending acts. Hopefully, this paper has shed light on this widely debated issue and has clarified the nature of the mistakes in recent interpretations of Husserl's concept of the noema. 相似文献

Using a self-paced moving window reading paradigm, we examine the degree to which structural commitments made while 60 Spanish-English L2 speakers read syntactically ambiguous sentences in their second language (L2) are constrained by the verb's lexical entry about its preferred structural environment (i.e., subcategorization bias). The ambiguity under investigation arises because a noun phrase immediately following a verb can be parsed as either the direct object of the verb 'The CIA director confirmed the rumor when he testified before Congress', or as the subject of an embedded complement 'The CIA director confirmed the rumor could mean a security leak'. In an experiment with 59 monolingual English participants, we replicate the findings reported in the previous literature demonstrating that native speakers are guided by subcategorization bias information during sentence interpretation. In a bilingual experiment, we then show that L2 subcategorization biases influence L2 sentence interpretation. The results indicate that L2 speakers keep track of the relative frequencies of verb-subcategorization alternatives and use this information when building structure in the L2. 相似文献

The phonological processing and memory skills of 12- and 13-year-old Italian children with difficulty in learning English as a foreign language (foreign language learning difficulty, FLLD) were examined and compared with those of a control group matched for age and nonverbal intelligence. Three experiments were conducted. A dissociation between verbal and visuo-spatial working memory was observed when compared to the control group; children with FLLD showed a poorer performance in a phonological working memory task but performed to a comparable level in a visuo-spatial working memory task (Experiment 1). In Experiment 2 the word length and the response modality of an auditory word span task were manipulated in order to examine the efficiency of the phonological loop and the relevance of the spoken output. The FLLD group did not show sensitivity to the word length effect and showed no advantage in the picture pointing recall condition. In Experiment 3 children with FLLD were shown to be sensitive to phonological similarity but again they showed neither a word length effect nor a slower articulation speed. Furthermore, in all three experiments children with FLLD were shown to be less efficient in phonological sensitivity tasks and this deficit appeared to be independent of the phonological memory problem. All three experiments consistently showed that children with FLLD have an impairment in phonological memory and phonological processing, which appear to be independent from one other but both contribute to the children's difficulty in learning a second language. 相似文献
