This note points out that using the finger as a test probe in a Fitts task may lead to misleading results, because of the increased target tolerance resulting from the width of the finger pad. An experiment demonstrates the need to use a corrected target width when calculating the index of difficulty; without this correction, information processing rates are overestimated. An example is given of a developmental study in which the finger pad size changes with age. The resulting changes in the calculated rates of information processing are shown to be markedly different for the different age groups. 相似文献

The spiral of distrust: (Non‐)cooperation in a repeated trust game is predicted by anger and individual differences in negative reciprocity orientation 下载免费PDF全文
This study investigated state anger and individual differences in negative reciprocity orientation as predictors of individuals' willingness to cooperate with strangers. In order to observe real behaviour, we used a trust game that was played over six periods. In the trust game, a first player (sender) determines how much of a certain endowment she/he wants to share with a second player (trustee), who then can give something back. We varied whether participants received feedback [feedback (yes, no)] about the trustee's behavioural decision (amount sent back). Supporting our hypotheses, the results suggest that feedback compared with no feedback about the trustee's behaviour increased anger. Specifically, information about low back transfers triggered anger and non‐cooperation in return. Importantly, participants with a strong negative reciprocity orientation reported higher levels of anger and were less willing to cooperate with the trustee compared with those with low negative reciprocity orientation. Moreover, even when anger was low, individuals with a strong negative reciprocity orientation were less willing to cooperate compared with those with a low negative reciprocity orientation. Thus, negative reciprocity orientation seems to arouse a spiral of distrust. Theoretical and practical implications of these findings are discussed. 相似文献

Five experiments are reported related to control of arm movement in the sagittal and transverse planes when making paced and unpaced movements. A single group of 12 participants and the same equipment were used in the main experiments to allow comparisons across conditions. As well as the 2 different directions of movement, there were movements that were time-constrained (as in the W. D. A. Beggs &; C. I. Howarth, 1971, 1972a,b paradigm) and movements that were constrained by the ending tolerance (as in Fitts' paradigm). Results showed that, for movement times as high as 900 ms, the Schmidt and Beggs and Howarth models appeared to describe the time for movements that had time constraint. Fitts' law (P. M. Fitts, 1954; P. M. Fitts &; J. R. Peterson, 1964) applied to movements that were constrained by final accuracy. These results were independent of whether the target was in the aiming or stopping movement direction. A new interpretation of data for movements with time constraint is presented, based on the possible number of accuracy submovements available when near the target. This model suggests that the standard deviation of hits at the target is not dependent on the time spent in reaching the target region, but largely on the time remaining in order to produce final accuracy at the target. 相似文献

Mortality salience effects on reckless driving intentions in a motorcyclist sample: The moderating role of group riding 下载免费PDF全文
Campaigns against reckless driving often mention the risk of dying. Research on terror management theory indicates that death claims may backfire and foster reckless driving. Here, we studied such mortality salience effects in a motorcyclist sample. Two moderating variables, particularly interesting regarding the sample of motorcyclists, were considered: group riding (vs. riding alone) and driving‐related self‐esteem. Motorcyclists were exposed to a campaign, either highlighting mortality or not. Orthogonally, cyclists were primed with riding in a group (vs. riding alone). Driving‐related self‐esteem was assessed via a questionnaire. We predicted that reminders of riding in a group would buffer against ironic mortality effects. Supporting this hypothesis, mortality salience effects interacted with the group prime. The results indicate that death appeals are likely to backfire with cyclists riding alone rather than cyclists riding in a group, especially if motorcycling is relevant to the self. 相似文献

Psychological inflexibility and experiential avoidance are equivalent (with somewhat different connotations) concepts and refer to an unwillingness to remain in contact with particular private events. This concept is most often measured by the Acceptance and Action Questionnaire (AAQ-II) and is strongly related to psychopathology and behavioral effectiveness. In this study, the preliminary psychometric properties of the Swedish version of the AAQ-II (Swedish Acceptance and Action Questionnaire—SAAQ) are presented. The study is done in two steps. In the first step, the 10-item version of the AAQ-II is investigated through principal component analysis (n = 147). Secondly, due to problems with the component structure, the instrument is reduced to a six-item version and its validity and internal consistency are investigated (n = 154). The six-item version shows good concurrent and convergent validity as well as satisfying internal consistency (α = .85). Furthermore, the Swedish six-item version of the AAQ-II showed one strong component. Test–retest reliability was satisfactory (r = .80; n = 228). In future research, predictive and external validity would be important to investigate in order to further ensure that the SAAQ is a useful measure for clinical research. In conclusion, the SAAQ has satisfactory psychometric properties, but more data need to be gathered to further explore the possibilities for the instruments in Swedish contexts. 相似文献

To what extent can individuals gain insight into their own or another person's implicit dispositions' We investigated whether self‐perceivers versus neutral observers can detect implicit dispositions from nonverbal behavioural cues contained in video feedback (cue validity) and whether these cues are in turn used as a valid basis for explicit dispositional inferences (cue utilization). Across three studies in the domains of extraversion and anxiety we consistently obtained reliable cue validity and cue utilization for neutral observers but not for self‐perceivers. An additional measure of state inferences in Study 3 showed that one reason for the lack of mediation in self‐perceivers is their reluctance to use their state inferences as a basis for more general trait inferences. We conclude that people have a ‘blind spot’ with respect to the nonverbal behavioural manifestations of their unconscious selves, even though neutral observers may readily detect and utilize this information for dispositional inferences.

It is argued that philosophers who adopt the perdurance theory of persistence and who subscribe to the principle of Unrestricted
Mereological Composition (UMC) are in a position to regard “Phosphorus is Hesperus” as false. 相似文献

Collett and Lizardo (2009) offer a model of gender differences that revisits and expands earlier research, in particular nascent ideas used by Miller and Hoffmann (1995) that were borrowed, in part, from a power-control theory of delinquency and crime. However, I am skeptical of their attempt to apply power-control theory as a general explanation of gender differences in religiousness. In this response piece, I first set the context by describing how Alan Miller and I initially approached our risk and religion work. I then point out where I think the research stream went awry and why recent studies of risk preferences and religion have failed to provide convincing evidence one way or the other. Finally, I offer an appraisal of Collett and Lizardo's work, with particular attention to why adopting power-control theory should be viewed with caution. I conclude with suggestions for future research on gender and religiousness. 相似文献

Up to now functional hemispheric asymmetries for global/local processing have mainly been investigated with hierarchical letters as stimuli. In the present study, three experiments were conducted to examine whether corresponding visual-field (VF) effects can also be obtained with more naturalistic stimuli. To this end, images of animals with a pattern placed on their body were displayed as stimuli. The task for the global level and for the local level was to categorize the animals and the patterns, respectively. As a result, VF-effects were also found for these stimuli and tasks. It is concluded that the hemispheric differences observed for hierarchical letters also hold for naturalistic stimuli. 相似文献
