Equal-hue discriminability steps for the pigeon are shown as tabular entries that can be summed or interpolated to produce sequences of equal discriminability steps of various step size. Equal-hue discriminability sequences can be constructed where the number of stimuli and spectral range are specified, or where an interval in one spectral region is to be equated to an interval in another spectral region. 相似文献

The spoken durations of rare and common words were compared in three experiments. Depending upon the task and the amount of practice, rare words (with frequencies less than 3 per million) were spoken as much as 24% slower than common words (with frequencies greater than 100 per million), when the words were equated for number of letters. This difference was observed even when the memory and lexical access demands of the task were minimized, and it can be explained by differences in the phonetic constituents of the two classes of words. The existence of these phonetic differences has been previously reported by Landauer and Streeter (1973) and by Zipf (1935). These findings argue against the view that all effects on the processing of accurately perceived words that are correlated with frequency may be unambiguously ascribed to operations that involve secondary memory (although this may be true of frequency effects per se). One recent experiment (Watkins, 1.977) is examined in light of these findings. 相似文献

A model for response latency in recognition memory is described which is a strength model incorporating the notion of multiple observations and with the additional assumptions that the variance of the strength distributions increase with set size and that the observer attempts to keep his error rate at a constant level over set size. It is shown that the model can, without recourse to particular parameter values, predict a near linear RT set-size function and, since it is a (TSD) model in its decision aspects, can account for errors and hence error latencies in the recognition task. After the model is described, two experiments are performed which test the prediction that correct mean latency is generally shorter than incorrect mean latency. The prediction is confirmed and this feature is discussed in general, the model being compared with that of Juola, Fischler, Wood, and Atkinson (1971) in this respect. Some possible modifications to the latter model are also considered. 相似文献

It is the purpose of this article to explicate the logical implications of a television analogy for perception, first suggested by John R. Smythies (1956). It aims to show not only that one cannot escape the postulation of qualia that have an evolutionary purpose not accounted for within a strong functionalist theory, but also that it undermines other anti-representationalist arguments as well as some representationalist ones.I should like to thank John R. Smythies for his helpful comments and advice. This article was written at the Swedish Collegium for Advanced Study in the Social Sciences, in Uppsala, Sweden. 相似文献

Subjects were presented with an easy or moderately difficult memorization task and told they could earn either a very low or very high chance of obtaining a modest prize if they did well. A measure of goal attractiveness was taken during an interval immediately preceding the task performance period. As expected, anticipatory goal attractiveness ratings were higher in the moderately difficult condition than in the easy condition when the probability of goal attainment (given success) was high, but were low in both task conditions when the probability of goal attainment (given success) was low. Results are discussed in terms of Brehm's recent theory of motivation. 相似文献

The following article examines creation-centered spirituality and leisure approaches to a way of life which gives healing and wholeness to individuals. Rather than limiting spirituality to mystics and saints, a wholistic spirituality based on the goodness of creation affirms the creativity in every person. Creative leisure is viewed as a necessary component of a spirituality which provides the basis for wholeness in humans. Not only the necessity of creative leisure for a vital Christian life for both laity and clergy but also its importance, particularly for those called to be ministers, is emphasized in the following essay.Gwen Laurie Wright, Ed.D. is a consultant in Spiritual Development. 相似文献

Tourette syndrome (TS) and chronic tic disorder (CTD) are neurological disorders of childhood onset characterized by the occurrence of tics; repetitive, purposeless, movements or vocalizations of short duration which can occur many times throughout a day. Currently, effective treatment for tic disorders is an area of considerable unmet clinical need. We aimed to evaluate the efficacy of a home-administered neuromodulation treatment for tics involving the delivery of rhythmic pulse trains of median nerve stimulation (MNS) delivered via a wearable ‘watch-like’ device worn at the wrist. We conducted a UK-wide parallel double-blind sham-controlled trial for the reduction of tics in individuals with tic disorder. The device was programmed to deliver rhythmic (10 Hz) trains of low-intensity (1–19 mA) electrical stimulation to the median nerve for a pre-determined duration each day, and was intended to be used by each participant in their home once each day, 5 days each week, for a period of 4 weeks. Between 18th March 2022 and 26th September 2022, 135 participants (45 per group) were initially allocated, using stratified randomization, to one of the following groups; active stimulation; sham stimulation or to a waitlist (i.e. treatment as usual) control group. Recruited participants were individuals with confirmed or suspected TS/CTD aged 12 years of age or upward with moderate to severe tics. Researchers involved in the collection or processing of measurement outcomes and assessing the outcomes, as well as participants in the active and sham groups and their legal guardians were all blind to the group allocation. The primary outcome measure used to assess the ‘offline’ or treatment effect of stimulation was the Yale Global Tic Severity Scale–Total Tic Severity Score (YGTSS–TTSS) assessed at the conclusion of 4 weeks of stimulation. The primary outcome measure used to assess the ‘online’ effects of stimulation was tic frequency, measured as the number of tics per minute (TPM) observed, based upon blind analysis of daily video recordings obtained while stimulation was delivered. The results demonstrated that after 4-week stimulation, tic severity (YGTSS-TTSS) had reduced by 7.1 points (35 percentile reduction) for the active stimulation group compared to 2.13/2.11 points for the sham stimulation and waitlist control groups. The reduction in YGTSS–TTSS for the active stimulation group was substantially larger, clinically meaningful (effect size = .5) and statistically significant (p = .02) compared to both the sham stimulation and waitlist control groups, which did not differ from one another (effect size = −.03). Furthermore, blind analyses of video recordings demonstrated that tic frequency (tics per minute) reduced substantially (−15.6 TPM) during active stimulation compared to sham stimulation (−7.7 TPM). This difference represents a statistically significant (p < .03) and clinically meaningful reduction in tic frequency (>25 percentile reduction: effect size = .3). These findings indicate that home-administered rhythmic MNS delivered through a wearable wrist-worn device has the potential to be an effective community-based treatment for tic disorders. 相似文献
