Earlier studies addressed the effects of feedback frequency on movement accuracy and consistency. The authors additionally addressed the effects on motor automatization. High error feedback frequencies may induce attentional control processes and impede motor automatization. In a pre-post design, 42 participants were assigned to 2 groups with different feedback frequencies and practiced an arm movement sequence with 760 trials in 5 sessions. The 100% group practiced with feedback on 3 movement reversals of the sequence after each trial. The 14% group practiced with 14% frequency according to a fading schedule. Only the 14% group showed a decrease in dual-task costs indicating an increase in automaticity. Group differences in movement accuracy and consistency were not evident. 相似文献

The trait-impulsivity etiological model assumes that a general factor (trait-impulsivity) underlies attention-deficit/hyperactivity disorder (ADHD), oppositional defiant disorder (ODD), and other externalizing disorders. We investigated the plausibility of this assumption by testing the factor structure of ADHD and ODD in a bifactor framework for a clinical sample of 1420 children between 6 and 18 years of age (M = 9.99, SD = 3.34; 85% male). Further, the trait-impulsivity etiological model assumes that ODD emerges only if environmental risk factors are present. Our results support the validity of the trait-impulsivity etiological model, as they confirm that ADHD and ODD share a strong general factor of disruptive behavior (DB) in this clinical sample. Furthermore, unlike the subdimensions of ADHD, we found that the specific ODD factor explained as much true score variance as the general DB factor. This suggests that a common scale of ADHD and ODD may prove to be as important as a separate ODD subscale to assess externalizing problems in school-age children. However, all other subscales of ADHD may not explain sufficient true score variance once the impact of the general DB factor has been taken into consideration. In accordance with the trait-impulsivity model, we also showed that all factors, but predominantly the general factor and specific inattention factor, predicted parent-rated impairment, and that predominantly ODD and impulsivity are predicted by environmental risk factors. 相似文献

A systemic phenomenological model that assumes the movability of the Cartesian cut is proposed and elucidated by means of
a single exploratory case study. The model assumes that a continuum from purely psychosomatic disorders to RSPK cases exists.
The degree of externalization (locus of control) of the affected person serves as an ordering parameter for the location of
the Cartesian cut. It turns out that the dynamics of the disorder develops in four phases, like in the RSPK-model of the MPI.
However, in contrast to the decline phase of the RSPK cases (because of the NT-axiom), CER cases lead to petrification of
the complaints. 相似文献

The present research reports the results of three studies showing that individuals with a fragile self‐concept in the domain of performance are particularly vulnerable to stereotype threat effects. Specifically, women who explicitly described themselves as rather mathematical but whose implicit self‐concepts contradicted these claims were vulnerable to stereotype threat effects on mathematical performance. This effect was robust across three studies, independent of the subtleness or content of the stereotype threat manipulation. Additionally, it was shown that the effect was mediated by anxious worrying (Study 3). Copyright © 2012 John Wiley & Sons, Ltd. 相似文献

In the context of the discussion about a reform of psychotherapeutic training in Germany the question arises, which factors influence the decision of psychologists and physicians for a particular training. 343 candidates in psychodynamic, behavioural or psychoanalytic training were asked about their motives for the training, their professional objectives in general and their satisfaction with their choice of training. The candidates' decision for a particular training was associated with personal attitudes and professional goals, with the given information about psychotherapeutic treatment within their studies and with their field of study. For the most part, the respondents are not satisfied with the quality and quantity of information on psychotherapeutic treatment within their studies. Candidates in analytic training are altogether more satisfied with their choice of training and do not plan to start an additional psychotherapeutic training as often as candidates in behavioral training. The consequences of these results in particular for the medical and psychological curricula (a more balanced representation of psychotherapeutic methods) are discussed. 相似文献

Flanker effects with faces may depend on perceptual as well as emotional differences 总被引:1,自引:0,他引:1
Do threatening or negative faces capture attention? The authors argue that evidence from visual search, spatial cuing, and flanker tasks is equivocal and that perceptual differences may account for effects attributed to emotional categories. Empirically, the authors examine the flanker task. Although they replicate previous results in which a positive face flanked by negative faces suffers more interference than a negative face flanked by positive faces, further results indicate that face perception is not necessary for the flanker-effect asymmetry and that the asymmetry also occurs with nonemotional stimuli. The authors conclude that the flanker-effect asymmetry with affective faces cannot be unambiguously attributed to emotional differences and may well be due to purely perceptual differences between the stimuli. 相似文献

The authors explored the effects of the components of a harm-doer's account of her transgression on the victims' emotional reactions to the transgression and to the character traits that she attributes to the harm-doer. Participants were 480 people whom the authors asked to imagine an incident in which they were harmed by the careless behavior of a friend. Subsequently, the authors offered participants an account of the harm-doer. In a 2 x 2 x 2 x 2 x 2 between-subjects design, the authors manipulated 5 account components: Admitting Fault, Admitting Damage, Expressing Remorse, Asking for Pardon, and Offering Compensation. The authors measured the participants' perceptions of these components. Results indicated that (a) the subjective perception of account components occurs schematically so that components are implicitly perceived without being objectively present, (b) objective components affect victims' reactions via subjective perceptions of these components, (c) personality factors (Irreconcilability, Interpersonal Trust, and Trait Anger) affect victims' reactions directly. Finally, certain configurations of account components are more effective than others. Specifically, asking for pardon had an effect on forgiving only when it was combined with an acknowledgment of the damage and a compensation offer. This result suggests that in this situation, the victim perceives a harm-doer's asking for pardon without the other components as an insincere apology. 相似文献

In three experiments, the authors investigated the impression formation process resulting from the perception of familiar or unfamiliar social category combinations. In Experiment 1, participants were asked to generate attributes associated with either a familiar or unfamiliar social category conjunction. Compared to familiar combinations, the authors found that when the conjunction was unfamiliar, participants formed their impression less from the individual constituent categories and relatively more from novel emergent attributes. In Experiment 2, the authors replicated this effect using alternative experimental materials. In Experiment 3, the effect generalized to additional (orthogonally combined) gender and occupation categories. The implications of these findings for understanding the processes involved in the conjunction of social categories, and the formation of new stereotypes, are discussed. 相似文献

Inductive probabilistic reasoning is understood as the application of inference patterns that use statistical background information
to assign (subjective) probabilities to single events. The simplest such inference pattern is direct inference: from “70%
of As are Bs” and “a is an A” infer that a is a B with probability 0.7. Direct inference is generalized by Jeffrey’s rule and the principle of cross-entropy minimization.
To adequately formalize inductive probabilistic reasoning is an interesting topic for artificial intelligence, as an autonomous
system acting in a complex environment may have to base its actions on a probabilistic model of its environment, and the probabilities
needed to form this model can often be obtained by combining statistical background information with particular observations
made, i.e., by inductive probabilistic reasoning. In this paper a formal framework for inductive probabilistic reasoning is
developed: syntactically it consists of an extension of the language of first-order predicate logic that allows to express
statements about both statistical and subjective probabilities. Semantics for this representation language are developed that
give rise to two distinct entailment relations: a relation ⊨ that models strict, probabilistically valid, inferences, and
a relation that models inductive probabilistic inferences. The inductive entailment relation is obtained by implementing cross-entropy
minimization in a preferred model semantics. A main objective of our approach is to ensure that for both entailment relations
complete proof systems exist. This is achieved by allowing probability distributions in our semantic models that use non-standard
probability values. A number of results are presented that show that in several important aspects the resulting logic behaves
just like a logic based on real-valued probabilities alone. 相似文献
