We proposed that intermittent evaluations of performance could be used to promote the acquisition of a complex skill. We also hypothesized that trainees low in need for cognition (NFC) would benefit more from intermittent evaluations compared to trainees high in NFC. Accordingly, 106 young adult males participated in 5 h of training in order to learn a complex computer task that simulated the demands of a dynamic aviation environment. Trainees’ performance was assessed either intermittently during training or at the end of training. Results indicated that intermittent performance evaluations enhanced the skill-based learning of trainees low in NFC, whereas intermittent skill evaluations tended to undermine the skill-based learning of trainees high in NFC. The findings are discussed in relation to Deci’s (1975) theory of intrinsic motivation and the need for more research examining attribute–treatment interactions with respect to training and skill acquisition. 相似文献

We have developed a process model that learns in multiple ways while finding faults in a simple control panel device. The model predicts human participants' learning through its own learning. The model's performance was systematically compared to human learning data, including the time course and specific sequence of learned behaviors. These comparisons show that the model accounts very well for measures such as problem-solving strategy, the relative difficulty of faults, and average fault-finding time. More important, because the model learns and transfers its learning across problems, it also accounts for the faster problem-solving times due to learning when examined across participants, across faults, and across the series of 20 trials on an individual participant basis. The model shows how learning while problem solving can lead to more recognition-based performance, and helps explain how the shape of the learning curve can arise through learning and be modified by differential transfer. Overall, the quality of the correspondence appears to have arisen from procedural, declarative, and episodic learning all taking place within individual problem-solving episodes. 相似文献

How does the knowledge of experts affect their behaviour in situations that require unusual methods of dealing? One possibility, loosely originating in research on creativity and skill acquisition, is that an increase in expertise can lead to inflexibility of thought due to automation of procedures. Yet another possibility, based on expertise research, is that experts' knowledge leads to flexibility of thought. We tested these two possibilities in a series of experiments using the Einstellung (set) effect paradigm. Chess players tried to solve problems that had both a familiar but non-optimal solution and a better but less familiar one. The more familiar solution induced the Einstellung (set) effect even in experts, preventing them from finding the optimal solution. The presence of the non-optimal solution reduced experts' problem solving ability was reduced to about that of players three standard deviations lower in skill level by the presence of the non-optimal solution. Inflexibility of thought induced by prior knowledge (i.e., the blocking effect of the familiar solution) was shown by experts but the more expert they were, the less prone they were to the effect. Inflexibility of experts is both reality and myth. But the greater the level of expertise, the more of a myth it becomes. 相似文献

This was an exploratory study examining the relationship between the therapist characteristics of age, experience, gender, and profession and the medical utilization of clients. Marriage and family therapists, clinical social workers, and psychologists participated in the study along with 197 clients as identified by archival research methods. The results of logistic regression analysis suggested that psychotherapy in general, rather than professional training or therapist characteristics is responsible for reductions in healthcare utilization. 相似文献

Practice not only affects how information is processed, but also which information is processed. The Information-Reduction
Hypothesis (i.e. Haider & Frensch, 1996) holds that — with practice — irrelevant task information (i.e. information that is
not logically needed to correctly perform the task) is discarded from processing. Recently, Gaschler and Frensch (2007) have
demonstrated that Information Reduction is not affected by the frequency with which individual task configurations are presented:
well-practiced and little-practiced irrelevant task configurations are discarded at the same point in time during practice;
Information Reduction is thus an item-general phenomenon. These findings suggest that Information Reduction is at least in
part a consequence of top-down, voluntary control. In the present research, we ask how tasks can be constructed such that
Information Reduction is avoided. Our results show that item-general Information Reduction is observed even when it leads
to severe processing costs (i.e. errors). On the whole, the present results are in line with models of skill acquisition incorporating
top-down modulation (e.g. Haider & Frensch, 2002) and are incompatible with purely data-driven accounts of skill acquisition
(e.g. Logan, 1988; Nosofski & Palmeri, 1997; Palmeri, 1997; Rickard, 2004). 相似文献

The purpose of this study was to determine the rate of utilization of Tay Sachs disease screening by the Ashkenazi Jewish population. Pregnant women who were referred to one of three genetic centers in New Jersey for amniocentesis unrelated to Tay Sachs screening were the study population. 4490 charts were reviewed retrospectively to determine the at risk population for Tay Sachs disease (Ashkenazi Jews) and whether or not patients and their spouses had elected Tay Sachs screening prior to referral. A group of 25 patients who did not elect screening were questioned as to their specific reason for declining Tay Sachs screening. Overall community utilization was 90%. Of the couples who did not elect screening, 64% felt that their risk to have an affected child was too small, 16% could not recall Tay Sachs screening being offered to them, 8% felt that screening was inconvenient. Tay Sachs screening as a voluntary preventive health care program has a high utilization rate in our study group. 相似文献

A theory of imitation is proposed, string parsing, which separates the copying of behavioural organization by observation from an understanding of the cause of its effectiveness. In string parsing, recurring patterns in the visible stream of behaviour are detected
and used to build a statistical sketch of the underlying hierarchical structure. This statistical sketch may in turn aid the
subsequent comprehension of cause and effect. Three cases of social learning of relatively complex skills are examined, as
potential cases of imitation by string parsing. Understanding the basic requirements for successful string parsing helps to
resolve the conflict between mainly negative reports of imitation in experiments and more positive evidence from natural conditions.
Since string parsing does not depend on comprehension of the intentions of other agents or the everyday physics of objects,
separate tests of these abilities are needed even in animals shown to learn by imitation.

Research shows that a large number of medical presentations do not result in a medical diagnosis but rather are related to behavioral health problems. Factors such as age, lower education and economic status, health beliefs, and medical and psychological factors are linked to high medical service utilization. Research consistently shows that patients with psychological problems use more services than those without diagnosable psychological problems. The purpose of this paper is to provide a more detailed analysis of the roles of psychological factors in medical presentations. We present three kinds of pathways by which psychological factors lead to medical presentations. These include the (1) primary or direct medical presentation of a clinical problem, (2) secondary presentation or the impact of the clinical problem on patients general physical, psychological, or psychosocial health, and (3) the complex presentation or the impact of multiple diagnoses on the presentation of the clinical problem. Examples of each of these pathways are presented for each axis of the DSM-IV. 相似文献

Animal expertise, conscious or not 总被引:1,自引:1,他引:0
Helton WS 《Animal cognition》2005,8(2):67-74
Rossano (Cognition 89:207, 2003) proposes expertise as an indicator of consciousness in humans and other animals. Since there is strong evidence that the development of expertise requires deliberate practice (Ericsson in The road to excellence: the acquisition of expert performance in the arts and sciences, sports and games 1996), and deliberate practice appears to be outside of the bounds of unconscious processing, then any signs of expertise development in an animal are indicators of consciousness. Rossanos argument may lead to an unsolvable debate about animal consciousness while causing researchers to overlook the underlying reality of animal expertise. This article provides evidence indicative of animals meeting each of the three definitions of expertise established in the scientific literature: expertise as a social construction, expertise as exceptional performance, and expertise as knowledge. In addition, cases of deliberate practice by non-human animals are offered. Acknowledging some animals as experts, regardless of consciousness, is warranted by the research findings and would prove useful in solving many issues remaining in the human expertise literature. 相似文献
