Frank Jackson has a new objectivist and representationalist account of the content of colour-experience. I raise several objections
both against the account itself and, primarily, against how he tries to support it. He argues that the new account enables
us to see what is wrong with the so-called Opacity Puzzle. This alleged puzzle is an argument in which a seemingly implausible
conclusion is derived from three premises of which seem plausible to an representationalist. Jackson’s diagnosis of the puzzle
as a fallacy of equivocation is mistaken. The term “the property of being red” is not ambiguous in the way he claims it to
be, and the puzzling argument is valid. Moreover, its conclusion is not implausible, so after all there is no real puzzle.
I try to show how Jackson’s wrong diagnosis results from neglecting the difference between properties proper and properties
as conceived in the light of a given property-concept. 相似文献

Nanotechnology seems to be a new “key-discipline”, which should lead to basic changes in many areas of living and producing.
This estimation is questioned by a comparison with established technologies, which reach from heat engines to biotechnology.
In this line it is possible to come to a more realistically assessment of nanotechnology. “Technologies” in the narrower sense
are understood as techniques based scientifically and integrated systematically into a network. The development of these technologies
starts first in the early modern times. Before this background the established technologies are characterised looking at relevant
questions and problems, the role of researchers and inventors, the importance of theoretical foundations, important applications
and innovations, as well as the relevance of visions and then confronted with nanotechnology in its present state. It is accentuated
that there are no explicit theories and no specific applications of nanotechnology and it seems to be only a kind of chemical
technology.

Gamma oscillations distinguish true from false memories 总被引:1,自引:0,他引:1

ABSTRACT— To test whether distinct patterns of electrophysiological activity prior to a response can distinguish true from false memories, we analyzed intracranial electroencephalographic recordings while 52 patients undergoing treatment for epilepsy performed a verbal free-recall task. These analyses revealed that the same pattern of gamma-band (28–100 Hz) oscillatory activity that predicts successful memory formation at item encoding—increased gamma power in the hippocampus, prefrontal cortex, and left temporal lobe—reemerges at retrieval to distinguish correct from incorrect responses. The timing of these oscillatory effects suggests that self-cued memory retrieval begins in the hippocampus and then spreads to the cortex. Thus, retrieval of true, as compared with false, memories induces a distinct pattern of gamma oscillations, possibly reflecting recollection of contextual information associated with past experience. 相似文献

Adolescent participation in structured activities, meaning those with adult leaders, regular meetings, and skill-building activities, is related to good adjustment. Participation in unstructured, unsupervised, peer-oriented activities is related to poor adjustment. Structured activity participation is high in early adolescence and then declines, raising the question of why youths leave structured activities. The authors examined explanations involving parents and peers. They used longitudinal data from 861 youths (ages 13-17 years). Results showed that, compared with youths who stayed in structured activities, those who switched to hanging out on the streets were less likely to have peers in structured activities and had less positive feelings about the home context and more negative interactions with parents. In addition, delinquency predicted switching to hanging out in the streets and never joining structured activities in the first place. The results concerning parents support a theoretical explanation of how parents might unintentionally affect youths' leisure choices. Furthermore, the authors found some indications that positive feelings at home might protect youths who switch from structured activities to hanging out on the streets from increases in delinquency. 相似文献

Recently, it has been shown that the perceived times of voluntary movements and their effects are perceived as shifted towards each other. This temporal binding phenomenon was explained by an integrated representation of movement and effect, facilitating operant learning and the experience of intentionality. Here, we investigated whether temporal binding depends on explicit intentional attributions. In Experiment 1, participants intended to either produce or avoid producing an effect (a tone) by the timing of their movements, with the ratio of success being fixed at 2:1. In Experiments 2 and 3, the influence of the action-effect contingency ratio on temporal binding was controlled for by removing the intentional attribution of the effect. The results indicate that temporal binding is a general associative mechanism that facilitates the learning of movement-effect contingencies. Beyond that, temporal binding is sensitive to explicit intentional attributions, which selectively enhance the link between an intentional movement and the effect a moving agent intends to produce. 相似文献

Four experiments demonstrate category congruency priming by subliminal prime words that were never seen as targets in a valence-classification task (Experiments 1, 2, and 4) and a gender-classification task (Experiment 3). In Experiment 1, overlap in terms of word fragments of one or more letters between primes and targets of different valences was larger than between primes and targets of the same valence. In Experiments 2 and 3, the sets of prime words and target words were completely disjoint in terms of used letters. In Experiment 4, pictures served as targets. The observed subliminal priming effects for novel primes cannot be driven by partial analysis of primes at the word-fragment level; they suggest instead that primes were processed semantically as whole words contingent upon prime duration. 相似文献

In the workplace, people can experience various types of failure and frustrations resulting in spontaneous social comparisons with other colleagues who are more (upward comparison) or less (downward comparison) successful. Upward comparisons especially have been shown to increase envy toward the outperforming benchmark colleague, which could negatively affect social interaction with this colleague. In line with this, our results consistently show that upward comparisons are associated with higher levels of experienced envy, as well as with a lower transmission rate of high-quality information. By contrast, type of social comparison had no impact on the amount of transmitted low-quality, work-relevant information. Theoretical and practical implications are discussed. 相似文献

ObjectivesAccording to regulatory focus theory, goal pursuit can be achieved by either keeping a promotion or a prevention focus [Higgins, E. T. (1997). Beyond pleasure and pain. American Psychologist, 52, 1280–1300; Higgins, E. T. (2000). Making a good decision: value from fit. American Psychologist, 55, 1217–1230]. Moreover, it has been assumed that people experience fit when they pursue a goal in a manner that sustains their chronic orientation and that fit has a positive impact on performance. In two studies, we investigated the significance of regulatory focus and fit in the realm of sports performance, such as the success rate in a soccer penalty-shooting task.Methods and ResultsIn a pilot study, we assessed the chronic regulatory orientation of 211 athletes from different sports. Among others, we found more promotion focus with attackers than with defenders. In the main study, we assessed the chronic regulatory orientation of 20 soccer players who took part in a penalty-shooting task. For half of them, the task was described in terms of promotion, for the others in terms of prevention. We found a positive impact of regulatory fit on scoring performance.ConclusionsOur findings demonstrate a great potential of regulatory focus theory for the understanding and enhancement of sport performance. The assessment of athletes' chronic regulatory orientation could be of importance for the selection of athletes, the adjustment of tactics and strategies, and coaches' framing of instructions. 相似文献

Psychological research is based in large parts on response latencies, which are often registered by keypresses on a standard computer keyboard. Recording response latencies with a standard keyboard is problematic because keypresses are buffered within the keyboard hardware before they are signaled to the computer, adding error variance to the recorded latencies. This can be circumvented by using external response pads connected to the computer's parallel port. In this article, we describe how to build inexpensive, reliable, and easy-to-use response pads with six keys from two standard computer mice that can be connected to the PC's parallel port. We also address the problem of recording data from the parallel port with different software packages under Microsoft's Windows XP. 相似文献

Standardized sets of films have been shown to be effective for eliciting emotional states in adults, but no comparable validated stimuli are available for children. We therefore examined the effects of three pre-selected film clips each of 3-min duration in eliciting a pleasant, neutral and unpleasant emotional state in 297 children aged between 6 and 12 years. After the films were presented on a video projector, affective ratings were obtained with the Self-Assessment-Manikin on the emotional dimensions of valence and arousal. Increasing pleasure ratings were observed from the unpleasant to the neutral to the pleasant film. Associated arousal ratings were stronger for the unpleasant and pleasant films compared to the neutral film. Overall, results showed successful elicitation of targeted emotional states only marginally influenced by age, gender or prior experience with the films. The use of these films is therefore suggested for future studies on emotions in children. 相似文献
