This study addresses a central question in perception of novel figurative language: whether it is interpreted intelligently and figuratively immediately, or only after a literal interpretation fails. Eighty sentence frames that could plausibly end with a literal, truly anomalous, or figurative word were created. After validation for meaningfulness and figurativeness, the 240 sentences were presented to 11 subjects for event related potential (ERP) recording. ERP's first 200 ms is believed to reflect the structuring of the input; the prominence of a dip at around 400 ms (N400) is said to relate inversely to how expected a word is. Results showed no difference between anomalous and metaphoric ERPs in the early window, metaphoric and literal ERPs converging 300-500 ms after the ending, and significant N400s only for anomalous endings. A follow-up study showed that the metaphoric endings were less frequent (in standardized word norms) than were the anomalous and literal endings and that there were significant differences in cloze probabilities (determined from 24 new subjects) among the three ending types: literal > metaphoric > anomalous. It is possible that the low frequency of the metaphoric element and lower cloze probability of the anomalous one contributed to the processes reflected in the early window, while the incongruity and near-zero cloze probability of the anomalous endings produced an N400 effect in them alone. The structure or parse derived for metaphor during the early window appears to yield a preliminary interpretation suggesting anomaly, while semantic analysis reflected in the later window renders a plausible figurative interpretation. 相似文献

The N170 is an event-related potential component associated with extrastriate visual mechanisms involved in detecting human faces and leading to their characteristic structural encoding. Consequently the N170 discriminates the processing of stimuli providing physiognomic information from the processing of other, similarly complex, visual patterns. We have used this effect to explore the top-down influence of newly acquired experience on the initial visual categorization of physiognomic stimuli. Schematic faces having the inner components mislocated did not elicit an N170 effect in naive participants. However, after normally configured versions of the schematic faces were exposed, suggesting what the ambiguous patterns represented, the same patterns elicited an N170 effect as conspicuous as that elicited by regular schematic faces. This priming effect, which changed the visual processing of distorted faces in extrastriate regions, could not be explained by post-perceptual decisions. Although accounts based on changes in focal attention, or within-vision constraints could not be categorically rejected, this outcome might suggest cognitive penetrability of early visual categorization. 相似文献

Helping Israeli bereaved parents work through losses and anger poses great emotional challenges for group therapists. Separation-individuation becomes an issue for both mourners and conductors alike. Supervision groups composed of such co-therapists often go through unique stages in the course of their development. The conflict between a defensive belonging to a dyadic subgroup with their co-therapist on the one hand, and involvement with the supervision group and its leader on the other, are the main reasons for this uniqueness. In these stages, special difficulties in the co-therapist's separation/individuation may be observed and furthered. An important emotional function we call reverse parallel process can be activated in supervision groups, and can eventually influence the therapy. It is achieved in the supervision through the containment and working through of difficult emotions disowned by the therapy group. What seemed to be an obstacle to the group's development, if processed by the co-therapists, can enable patients to work through their difficulties and improve their functioning. If, on the other hand, the co-therapists' separation/individuation development is faulty, containment dysfunction may burden the receptiveness and working through of dreadful projections, and result in massive acting-out. The rich Israeli experience in this field could contribute to cope with similar group situations. 相似文献

Post-choice information processing by pigeons 总被引:2,自引:2,他引:0
In a conditional discrimination (matching-to-sample), a sample is followed by two comparison stimuli, one of which is correct, depending on the sample. Evidence from previous research suggests that if the stimulus display is maintained following an incorrect response (the so-called penalty-time procedure), acquisition by pigeons is facilitated. The present research tested the hypothesis that the penalty-time procedure allows the pigeons to review and learn from the maintained stimulus display following an incorrect choice. It did so by including a penalty-time group for which, following an incorrect choice, the sample changed to match the incorrect comparison, thus providing the pigeons with post-choice misinformation. This misinformation group acquired the matching task significantly slower than the standard penalty-time group (that had no change in the sample following an error). Furthermore, acquisition of matching by a control group that received no penalty time fell midway between the other two groups, suggesting that the pigeons did not merely take more care in making choices because of the aversiveness of penalty-time. Thus, it appears that in the acquisition of matching-to-sample, when the stimulus display is maintained following an incorrect choice, the pigeons can review or acquire information from the display. This is the first time that such an effect has been reported for a nonhuman species. 相似文献

Group choice refers to the distribution of group members between two choice alternatives over time. The ideal free distribution (IFD), an optimal foraging model from behavioral ecology, predicts that the ratio of foragers at two resource sites should equal the ratio of obtained resources, a prediction that is formally analogous to the matching law of individual choice, except that group choice is a social phenomenon. Two experiments investigated the usefulness of IFD analyses of human group choice and individual-based explanations that might account for the group-level events. Instead of nonhuman animals foraging at two sites for resources, a group of humans chose blue and red cards to receive points that could earn cash prizes. The groups chose blue and red cards in ratios in positive relation to the ratios of points associated with the cards. When group choice ratios and point ratios were plotted on logarithmic coordinates and fitted with regression lines, the slopes (i.e., sensitivity measures) approached 1.0 but tended to fall short of it (i.e., undermatching), with little bias and little unaccounted for variance. These experiments demonstrate that an IFD analysis of group choice is possible and useful, and suggest that group choice may be explained by the individual members' tendency to optimize reinforcement. 相似文献

What's different in second-language processing? Evidence from event-related brain potentials 总被引:1,自引:0,他引:1

German sentences which were either correct, contained a selectional restriction violation, or a word category violation were presented auditorily to 16 native speakers of German (L1 group) and to 16 native speakers of Russian, who had learned German after the age of 10 (L2 group). Semantic violations elicited an N400 effect for both groups, but with a reduced amplitude and a longer peak latency in the L2 group. Compared to correct sentences, sentences with a phrase structure violation elicited an early anterior negativity followed by a broad centro-parietal positivity in native speakers. By contrast, there was no differential modulation of the early anterior negativity in the L2 group. A late positivity was also elicited in the second language learners, but it was slightly delayed compared to that shown by native speakers. This pattern is discussed in terms of different degrees of automaticity with respect to the subprocesses involved in sentence comprehension. 相似文献

Locally ambiguous NP1 NP2 V clauses in Dutch are preferably assigned a subject-object rather than an object-subject interpretation, presumably on the basis of structurally based principles such as the Active-Filler Strategy. The present study investigates whether this preference can be affected by a nonconfigurational factor, namely the nature of NP2. The type of an NP (indefinite NPs, full definite NPs, pronouns) conveys information about the discourse status of the NP referent, which, in turn, is associated with a specific syntactic position. More specifically, pronouns are used to refer to given, salient entities in the discourse (topics); and NPs with such referents are generally encoded in subject position. A self-paced reading experiment shows that NP1 NP2 V relative clauses are preferably interpreted as subject-object when NP2 is a full definite NP (e.g., de vrouwen the women), but not when NP2 is the second person pronoun jullie (you-PL). This suggests that the structural bias for a subject-first order is not as strong as has been previously assumed, but is influenced by discourse information encoded in the NPs. Implications for parsing models are discussed. 相似文献

In this study we examined the factor structure of the Child Behavior Checklist (CBCL) filled out by group care workers. Group care workers' judgements were collected on 846 children and adolescents treated in various residential settings in The Netherlands. Using confirmatory factor analysis, we were able to show that the original CBCL factor model based on parental judgments of child behavior also fits for the judgments of group care workers. This means that the well known 8 narrow-band syndromes (Withdrawn, Somatic Complaints, etc.) as well as the 2 broad-band syndromes (Internalizing and Externalizing) can be used to interpret the CBCL scores of group care workers. This confirmation of the CBCL factor structure is a first step to add a group care worker version to the CBCL family. However, as a second step, normative data need to be gathered to further enhance the use of the CBCL for group care workers. 相似文献

The link between automatic and effortful processing and nonanalytic and analytic category learning was evaluated in a sample of 29 college undergraduates using declarative memory, semantic category search, and pseudoword categorization tasks. Automatic and effortful processing measures were hypothesized to be associated with nonanalytic and analytic categorization, respectively. Results suggested that contrary to prediction strong criterion-attribute (analytic) responding on the pseudoword categorization task was associated with strong automatic, implicit memory encoding of frequency-of-occurrence information. Data are discussed in terms of the possibility that criterion-attribute category knowledge, once established, may be expressed with few attentional resources. The data indicate that attention resource requirements, even for the same stimuli and task, vary depending on the category rule system utilized. Also, the automaticity emerging from familiarity with analytic category exemplars is very different from the automaticity arising from extensive practice on a semantic category search task. The data do not support any simple mapping of analytic and nonanalytic forms of category learning onto the automatic and effortful processing dichotomy and challenge simple models of brain asymmetries for such procedures. 相似文献

The group therapist often and perhaps necessarily personifies Incohesion and displays its predominant defenses of contact-shunning Aggregation, and merger-hungry Massification. Hence, I am I:A/M. In Hopper's group example, and in each of three of this author's groups, the therapist displayed aggregative and massified defenses, countertansferential duals of basic assumptive transferences. In any therapeutic interaction, it is possible to find elements of incohesion, dependency, pairing, and fight/flight. The incohesion concept has significant clinical utility. A theoretical question remains, whether Hopper's proposed axis of experience and defense merits the special status, basic assumption, or whether incohesion may be collapsed into the existing triad of basic assumptions. 相似文献
