Positron emission tomography was used to investigate two competing hypotheses about the role of the left inferior frontal gyrus (IFG) in word generation. One proposes a domain-specific organization, with neural activation dependent on the type of information being processed, i.e., surface sound structure or semantic. The other proposes a process-specific organization, with activation dependent on processing demands, such as the amount of selection needed to decide between competing lexical alternatives. In a novel word retrieval task, word reconstruction (WR), subjects generated real words from heard non-words by the substitution of either a vowel or consonant. Both types of lexical retrieval, informed by sound structure alone, produced activation within anterior and posterior left IFG regions. Within these regions there was greater activity for consonant WR, which is more difficult and imposes greater processing demands. These results support a process-specific organization of the anterior left IFG.  相似文献

The efficacy of the dyadic psychoanalytic method cannot be verified empirically, due to the impossibility of counterfactuals, controls, or double-blind experiments, although inventive psychoanalytic researchers have established validation methodologies for analyzing groups of case studies, outcomes, and even theoretical precepts. The unavailability of complete empirical validation for the most basic method of the discipline of psychoanalysis, or of its fundamental "report of findings"--the case study--means that the field's scientific rationale must be supplemented with public reasoning of another sort. Fortunately, the very conditions of uncertainty that make it impossible to falsify the findings of dyadic psychoanalysis lend it its ethical force by compelling its participants to confront the basic human dilemmas of freedom, meaning, and judgment, the ethical horizon of human affairs. One substantial value of psychoanalysis, then, is its capacity for generating "ethical knowledge" of the sort adumbrated by Aristotle's conception of practical knowledge (phronesis). Case studies written for a lay audience to highlight these basic dilemmas can demonstrate that psychoanalysis produces crucial knowledge, specific to individuals, for living a healthy and satisfying life.  相似文献

Feelings of positive or negative affect are not restricted to temporary states. They can also determine future affective experiences, by influencing the building of an individual’s personal resources. The present study was designed to understand the daily fluctuations in positive and negative affect more fully. To this end, we examined the involvement of a variety of affect regulation strategies in these fluctuations. The affect regulation strategies we explored included positive reappraisal, problem-focused coping, appreciation and rumination. We adopted an experience sampling method, consisting of five daily assessments over a 2-week period. As expected, within a few hours of experiencing more positive affect, participants engaged in greater positive reappraisal, problem-focused coping and appreciation. In turn, greater use of each of these three strategies was followed by more intense experiences of positive affect. We observed analogous reciprocal influences between rumination and the experience of negative affect, within the same time interval. Changes in affective experience over several hours were also directly influenced by concurrent use of these strategies. More specifically, greater positive reappraisal, problem-focused coping and appreciation accelerated the rise in positive affect that follows low feelings of positive affect, and slowed the decline in positive affect that follows high feelings. Rumination had an analogous influence on change in negative affect. The clinical implications of these findings are discussed.  相似文献

Research suggests that a feature-matching process underlies cue familiarity-detection when cued recall with graphemic cues fails. When a test cue (e.g., potchbork) overlaps in graphemic features with multiple unrecalled studied items (e.g., patchwork, pitchfork, pocketbook, pullcork), higher cue familiarity ratings are given during recall failure of all of the targets than when the cue overlaps in graphemic features with only one studied target and that target fails to be recalled (e.g., patchwork). The present study used semantic feature production norms (McRae et al., Behavior Research Methods, Instruments, & Computers, 37, 547–559, 2005) to examine whether the same holds true when the cues are semantic in nature (e.g., jaguar is used to cue cheetah). Indeed, test cues (e.g., cedar) that overlapped in semantic features (e.g., a_tree, has_bark, etc.) with four unretrieved studied items (e.g., birch, oak, pine, willow) received higher cue familiarity ratings during recall failure than test cues that overlapped in semantic features with only two (also unretrieved) studied items (e.g., birch, oak), which in turn received higher familiarity ratings during recall failure than cues that did not overlap in semantic features with any studied items. These findings suggest that the feature-matching theory of recognition during recall failure can accommodate recognition of semantic cues during recall failure, providing a potential mechanism for conceptually-based forms of cue recognition during target retrieval failure. They also provide converging evidence for the existence of the semantic features envisaged in feature-based models of semantic knowledge representation and for those more concretely specified by the production norms of McRae et al. (Behavior Research Methods, Instruments, & Computers, 37, 547–559, 2005).  相似文献

Recent studies have explored ways to increase cognitive load in liars to identify cues to deception. This study used a driving simulator as a load‐inducing technique to explore differences between truth‐tellers and liars during an investigative interview scenario and also investigated the effect of rehearsing lies in this context. Deception affected driving performance. Truth‐tellers drove more slowly compared with their own baseline, whereas unrehearsed liars sped up. There was no difference in speed between truth‐tellers and rehearsed liars. In addition, truth‐tellers had significantly faster reaction times compared with their own baseline, than both rehearsed and unrehearsed liars. During the interviews, truth‐tellers provided significantly more visual and auditory details and mentioned significantly fewer cognitive operations than liars. The findings add to the body of literature exploring the optimal relationship between cognitive load and secondary task performance to identify cues to deception.Copyright © 2015 John Wiley & Sons, Ltd.  相似文献

Few studies have isolated the preventive efficacy of common behavioral strategies like noncontingent reinforcement (NCR) and differential reinforcement of alternative behavior (DRA). The purpose of the current study was to develop and evaluate a laboratory model of these two problem behavior prevention strategies. Undergraduate students participated in a computer simulation, in which clicks to a designated area of the computer screen were analogous to the emergence of problem behavior. The responding of participants in a control group, who experienced a percentile schedule used to mimic the shaping of problem behavior, was compared to that of participants in two experimental groups, each with a history of either DRA or NCR. Between‐subjects group comparisons showed that both intervention strategies were equally effective in the prevention of our analog to problem behavior when compared to the control group. The strengths and limitations of a laboratory model for prevention are discussed in light of recent applied work in this area.  相似文献

The effectiveness of a behavioral skills training (BST) package to teach the implementation of the first three phases of the picture exchange communication system (PECS) was evaluated with 3 adults who had no history teaching any functional communication system. A multiple baseline design across participants was used to evaluate the effectiveness of the training package, which consisted of a video, written and verbal instructions, modeling, rehearsal, and feedback. Results showed significant improvements relative to baseline in a short amount of training time and that skills generalized to a learner with a severe developmental disability. Skills were maintained at 1 month follow‐up for 1 participant.  相似文献

Taking its cue from Ekstein's analysis of the history of supervision (1960), this article proposes that there is a new historical era emerging in Britain, a phase that could be characterised as the ‘regulatory phase’. It is argued that in the future the clinical supervisor of psychoanalytic work will be positioned as ‘overseer’, with the consequence that what might be overlooked/not seen in the new regulatory climate is the notion of a psychoanalytically informed practice as a practice of the questioning of knowledge and its effects. Further, it considers how the effect of the proposed regulatory framework for psy-practice in the UK elides the current distinction between ‘practitioner/analyst’ and ‘trainee/candidate’. Thus psychoanalytically informed practitioners are re-positioned as candidates for authorisation as state licensed psy-practitioners. A clinical example, based loosely on Freud's account of his analysis of the young female homosexual, draws attention to the specifics and problematics of the competencies for analytic work and its supervision proposed by the Health Professions Council, Skills for Health and research for University College London, which envisages a future role of supervisors as the overseers of standardised interventions.  相似文献
