The ability to deal with sources of conflict, that is, interference control, was evaluated in a group of 11 children with first episode Major Depression and a peer control group. To this end, the Eriksen and Schultz (1979) task was used. Here, the participant is presented with a stimulus that simultaneously activates two conflicting response channels: One response is activated by the instructions, whereas the other response is activated by elements in the array that strongly invite an alternative — yet incorrect — response. Findings provided no evidence for an undisturbed interference control nor impaired overall processing speed in children with first episode Major Depression. 相似文献

In this article, we trace and elucidate Heidegger’s radical re-thinking on the relation between science and technology from about 1940 until 1976. A range of passages from the Gesamtausgabe seem to articulate a reversal of the primacy of science and technology in claiming that “Science is applied technology.” After delving into Heidegger’s reflection on the being of science and technology and their “coordination,” we show that such a claim is essentially grounded in Heidegger’s idea that “Science and technology are the Same [das Selbe].” In addition, we argue that, although different ontic epochs can be distinguished in the evolvement of science and/or technology, for Heidegger there is only one unique ontological Epoch of modernity that encompasses various ontic epochs. Therefore, the change from an “epoch of objectivity” to an “epoch of orderability [Bestellbarkeit]” cannot be considered to be an ontological shift. Furthermore, it is not right to ascribe to Heidegger the view that the development of quantum physics signals the beginning of a new ontological Epoch. 相似文献

Introduction
Humans experience touch as pleasant when this occurs with a certain velocity (1–10cm/s). Affective, pleasant touch is thought to be mediated by a distinct neural pathway consisting of un-myelinated tactile afferents (C tactile fibers) that respond to stroking with a low velocity on the hairy skin. As pleasant touch provides additional information on bodily signals we hypothesized that, compared to regular touch, pleasant touch would have a stronger effect on body ownership as measured through induction of the rubber hand illusion (RHI).Methods
Two experiments involving the RHI were conducted. In the first experiment, the effects of stroking velocity (3 cm/s and 30 cm/s) and stroking material (soft/rough) on the RHI were tested. In the second experiment, the effect of an additional stroking velocity (0.3 cm/s) and side of stimulation (hairy and glabrous) was examined.Results
The first experiment showed that low velocity stroking in combination with a soft material was not only regarded as most pleasant but also resulted in an enhanced RHI on proprioceptive drift and temperature measurements. In the second experiment, we confirmed that stroking with a velocity of 3 cm/s resulted in a larger RHI in terms of proprioceptive drift. In addition, compared to regular touch, pleasant touch of the hairy skin resulted in a larger proprioceptive drift, while similar stroking on the glabrous side of the skin did not induce a stronger effect of RHI on proprioceptive drift.Conclusion
Our data suggest that pleasant touch modulates the body representation which is consistently reflected in a larger proprioceptive drift. Our data also suggest that C tactile fibers are likely to be involved in the modulation of body ownership. 相似文献195.
It has frequently been claimed that learning performance improves with practice according to the so-called “Power Law of Learning.”
Similarly, forgetting may follow a power law. It has been shown on the basis of extensive simulations that such power laws
may emerge through averaging functions with other, nonpower function shapes. In the present article, we supplement these simulations
with a mathematical proof that power functions will indeed emerge as a result of averaging over exponential functions, if
the distribution of learning rates follows a gamma distribution, a uniform distribution, or a half-normal function. Through
a number of simulations, we further investigate to what extent these findings may affect empirical results in practice. 相似文献

The literature on how people solve moral dilemmas often focuses on situations in which individuals have to make a decision where different moral rules are in conflict. In some of these situations, such as in footbridge dilemmas, people have to choose between sacrificing a few people in order to save many. The present research focuses on how people decide what to do in dilemmas involving conflicting moral rules. We propose that the rule that is cognitively most accessible during the decision making process (e.g., “Save lives” or “Do not kill”) will influence how people solve these moral dilemmas. Three studies are reported that indeed demonstrate that the most accessible rule influences willingness to intervene within footbridge dilemmas. This effect is found even when the accessibility of the rule is induced subliminally. 相似文献

This study validates the Sensitivity to Punishment and Sensitivity to Reward Questionnaire for children (SPSRQ-C), using a
Dutch sample of 1234 children between 6–13 years old. Factor analysis determined that a 4-factor and a 5-factor solution were
best fitting, explaining 41% and 50% of the variance respectively. The 4-factor model was highly similar to the original SPSRQ
factors found in adults (Punishment Sensitivity, Reward Responsivity, Impulsivity/Fun-Seeking, and Drive). The 5-factor model
was similar to the 4-factor model, with the exception of a subdivision of the Punishment Sensitivity factor into a factor
with ‘social-fear’ items and a factor with ‘anxiety’ items. To determine external validity, scores of three groups of children
with attention deficit hyperactivity disorder (ADHD) were compared on the EFA models: ADHD-only (n = 34), ADHD and autism spectrum disorder (ADHD+ASD; n = 22), ADHD and oppositional defiant disorder (ADHD+ODD; n = 22). All ADHD groups scored higher than typical controls on Reward Responsivity and on the ‘anxiety’ factor (n = 75). The ADHD-only and ADHD+ODD group scored higher than other groups on Impulsivity/Fun-Seeking and Drive, while the ADHD+ASD
group scored higher on Punishment Sensitivity. The findings emphasize the value of the SPSRQ-C to quickly and reliably assess
a child’s sensitivity to reinforcement, with the aim to provide individually-tailored behavioral interventions that utilize
reward and reprimands. 相似文献

Abstract Emotions can be regarded as the manifestations of a system that realises multiple concerns and operates in an uncertain environment. Taking the concern realisation function as a starting point, it is argued that the major phenomena of emotion follow from considerations of what properties a subsystem implementing that function should have. The major phenomena are: the existence of the feelings of pleasure and pain, the importance of cognitive or appraisal variables, the presence of innate, pre-programmed behaviours as well as of complex constructed plans for achieving emotion goals, and the occurrence of behavioural interruption, disturbance and impulse-like priority of emotional goals. The system properties underlying these phenomena are facilities for relevance detection of events with regard to the multiple concerns, availability of relevance signals that can be recognised by the action system, and facilities for control precedence, or flexible goal priority ordering and shift. A computer program, ACRES, is described that is built upon the specifications provided by this emotion theory. It operates in an operator-machine interaction involving the task of executing a knowledge manipulation task (the knowledge domain happens to be about emotions). ACRES responds emotionally when one of his concerns (e.g. errorless input, being kept busy, receiving varied input, not being killed) is touched upon. Responses are social signals, shifts in resource allocations to the operator, interruption of current task-directed processing, and refusal to accept instructions. His flow of behaviour shows much of the preference-based predictability, response interference, goalshifts, and social signalling of human and animal emotional behaviour. 相似文献

Most financial–economic decisions are made consciously, with a clear and constant drive to ‘good’, ‘better’ or even ‘optimal’ decisions. Nevertheless, many decisions in practice do not earn these qualifications, despite the availability of financial economic theory, decision sciences and ample resources. We plea for the development of a multidimensional framework to support financial economic decision processes. Our aim is to achieve a better integration of available theory and decision technologies. We sketch (a) what the framework should look like, (b) what elements of the framework already exist and which not, and (c) how the MCDA community can co‐operate in its development.
