Empirical data indicate that when memory for subspan lists of taxonomically related material is tested immediately after study, prior experience with lists involving the same material has no effect upon recall or recognition. In six experiments, we explored the possibility that immunity to proactive interference (PI) is related to discriminative information that is provided by transient phonemic codes. In these experiments, we manipulated the strength of phonemic codes as well as their presence or absence. Immunity to PI was found only when it was presumed that a phonemic representation of the target items existed and that information provided discriminative information. In all other cases, PI was observed. The finding that PI effects correspond with the manipulation of phonemic information in a principled fashion provides strong evidence for the role of phonemic codes in producing short-term PI effects. 相似文献

The fundamental frequency (F0) of the voice is used to convey information about both linguistic and affective distinctions. However, no research has directly investigated how these two types of distinctions are simultaneously encoded in speech production. This study provides evidence thatF0 prominences intended to convey linguistic or affective distinctions can be differentiated by their influence on the amount of final-syllableF0 rise used to signal a question. Specifically, a trading relation obtains when theF0 prominence is used to convey emphatic stress. That is, the amount of finalsyllableF0 rise decreases as theF0 prominence increases. When theF0 prominence is used to convey affect, no trading relation is observed. 相似文献

Previous research has found that test takers can score above chance level on reading comprehension tests even when the passages are omitted. The present research investigated whether the effect would vary as a function of race. In Study 1, 386 participants completed a reading test with the passages omitted. General mental ability and race were significantly correlated with test performance. In Study 2, 827 job applicants completed the test as part of an entry-level selection battery. Eliminating items for which large race differences existed in Study 1 had no real effect on the size of the Black-White mean difference. 相似文献

Abstract— Dealing with the problems of substance abuse requires both an appreciation of clinical reality and an understanding of basic psychosocial principles. Each of the conference presentations of theory and research most of them nonapplied in nature, created a welcome and rare occasion for experimental and clinical psychologists (and hybrids) to reflect together on the applied implications of some basic research and on the research implications of some applied professional activities. Among the issues found especially noteworthy by this discussant. Here the following the return of cognition and rational decision making as legitimate and critical foci in behavior therapy, the role of exposure to aversive events in reducing their fearsomeness, the advantages of not working doggedly to achieve goals that are better approached with a nonachievement attitude the possibility that the difficulty in altering pathological behavior derives from the properties of human language, appreciation of individual differences in psychotherapy outcome research, the importance of considering the meaning that therapeutic ministrations can have for certain patients, and the need to reexamine the utility of patients expressing their concerns. 相似文献

887 respondents completed ipsative and normative versions of the PAL-TOPAS personality questionnaire. Data were analysed to test for (1) systematic bias in scores associated with the two response formats and (2) predictors of the magnitude of the discrepancy in the individual's ipsative and normative scores. Discrepancy was assessed for both item responses and scale scores. Sources of biases investigated included ipsative scaling artifact, extremeness of scores on the normative scales and response variability. Results showed that systematic bias in scale scores and magnitude of discrepancy were predicted by different factors. One source of systematic bias was associated with ipsative scaling artifact: the ipsative scales measure both the scale itself and rejection of other alternatives. A second source of systematic bias was acquiescence in response to normative items. A confirmatory factor analysis showed that a good but imperfect fit to the data may be obtained by constructing a structural model of the inter-relationship between normative and ipsative scores which accommodates both sources of bias. The strongest influence on discrepancy in scale scores was extremeness of normative scoring, associated with a bias towards either general acceptance or rejection of trait adjectives. It is concluded that both normative and ipsative response formats have limitations, and it may often be desirable to assess both. 相似文献

First through fourth graders from 22 suburban elementary schools were screened for cross-setting disruptive behavior as eligibility criteria for participation in a longitudinal secondary prevention study aimed at reducing the risk for serious externalizing behavioral disorders. Three hundred nine subjects participated in either a multicomponent competence enhancement intervention (MCEI) or an information/attention control (IAC) condition over a 2-year period. Following baseline measurements, initial intervention effects were assessed at the end of intervention Year 1, at the beginning of intervention Year 2 (fall of the next school year), and at the end of intervention Year 2. Multisource assessments were not supportive of the efficacy of the MCEI over the IAC condition. Children in both groups rated themselves as improved over time in terms of increased adaptive skills and decreased school problems and internalizing symptoms. Teacher and parent ratings of externalizing behavior did not yield evidence of positive change, but teachers noted improved problem solving and observers noted a decrease in behavioral interference in both groups over time, possibly as a result of maturation. 相似文献

A long-term follow-up of echolalia and correct question answering was conducted for 6 subjects from three previously published studies. The follow-up periods ranged from 26 to 57 months. In a training site follow-up, subjects were exposed to baseline/posttraining conditions in which the original trainer and/or a novel person(s) presented trained and untrained questions. Four subjects displayed echolalia below baseline levels, and another did so in some assessments. Overall, echolalia was lower than in baseline in 80.6% of the follow-ups. Five subjects displayed correct responding above baseline levels. No clear differences were noted in correct responding or echolalia between the trainer and novel-person presentations or between trained and untrained questions. In a follow-up in a natural environment conducted by a novel person, lower than baseline levels of echolalia were displayed by 3 subjects; 2 subjects displayed lower than baseline levels in some assessments. Two subjects consistently displayed correct responding above baseline, and 3 did so occasionally. Issues related to the study of maintenance are discussed. 相似文献

Semantic Holism is the claim that any semantic path from inferential semantics (the indeterminate semantics forced by the classical inference rules of PC) reaches all the way to classical semantics if it is even one step long. In our joint paper Semantic Holism, Belnap and I showed that some such semantic paths are two steps long, but we left open a number of questions about the lengths of semantic paths. Here I answer the most important of these questions by showing that there are infinitely long semantic paths that begin at inferential semantics but that do not even reach classical semantics. I do this by showing how to construct such an infinite semantic path from the members of the family of (n–1)-out-of-n-disjunction connectives. 相似文献

Of a consecutive series of 115 boys diagnosed in a university outpatient clinic as ADHD, 39% also demonstrated a specific reading disability. Pure ADHD patients were compared with mixed ADHD + RD and normal controls on a battery of cognitive and attentional measures. The aim was to determine whether a distinct pattern of deficits would distinguish the groups. Both ADHD subgroups performed significantly worse than controls on measures of sequential memory and attentional tasks involving impulse control andplanful organization. Only ADHD+RD boys differed from controls on measures or rapid word naming and vocabulary. The reuslts are discussed within the framework of an automatic versus effortful information-processing model. 相似文献
