Self-controlling practice implies a process of decision making, which suggests that the options in a self-controlled practice condition could affect learners. The number of task components with no fixed position in a movement sequence may affect the way learners self-control their practice. A 200-cm coincident timing track with 90 light-emitting diodes (LEDs)--the first and the last LEDs being the warning and the target lights, respectively--was set so that the apparent speed of the light along the track was 1.33 m/sec. Participants were required to touch six sensors sequentially, the last one coincidently with the lighting of the target light (timing task). Group 1 (n = 55) had only one constraint, and were instructed to touch the sensors in any order, except for the last sensor which had to be the one positioned close to the target light. Group 2 (n = 53) had three constraints: the first two and the last sensor to be touched. Both groups practiced the task until timing error was less than 30 msec. on three consecutive trials. There were no statistically significant differences between groups in the number of trials needed to reach the performance criterion, but (a) participants in Group 2 created fewer sequences compared to Group 1, and (b) were more likely to use the same sequence throughout the learning process. The number of options for a movement sequence affected the way learners self-controlled their practice, but had no effect on the amount of practice to reach criterion performance. 相似文献

Inter- and intra-judge reliabilities of skinfold measures were investigated in a sample of 27 men and 11 women ultramarathon runners. Two physicians had agreement higher than 90% in field measurements before an ultramarathon race. 相似文献

The current project investigated why people with high levels of Openness/Intellect tend to have higher levels of cognitive functioning than people with lower levels of Openness/Intellect. We hypothesized that the positive relationship between Openness/Intellect and cognition might be attributable to more open people being more likely to engage in cognitively stimulating activities that are beneficial for cognitive functioning. Three conceptualizations of activity engagement based on: (a) self ratings of duration and intensity of engagement; (b) perceived routineness of one's activities; and (c) disposition to engage in cognitively stimulating activities, were investigated as possible mediators of the Openness/Intellect-cognition relations. Although several of the relevant simple correlations were of moderate size and statistically significant, we found little evidence that activity engagement mediated the relations between Openness/Intellect and cognition. 相似文献

We show that human observers using monocular viewing treat the pencil of 'visual rays' that diverges from the vantage point as experientally parallel. This oddity becomes very noticeable in the case of wide-angle presentations, where the angle subtended by a pair of visual rays may be as large as the angular size of the display. In our presentations such angles subtended over 100 deg. There are various ways to demonstrate the effect; in this study we measure the attitudes of pictorial objects that appear to be situated in mutually parallel attitudes in pictorial space. Our finding is that such objects appear parallel if they are similarly oriented with respect to the local visual rays. This leads to 'errors' in the judgment of mutual orientations of up to 100 deg. Although this appears to be the first quantitative study of the effect, we trace it to qualitative reports by Helmholtz (late 19th century) and Kepler (early 17th century) as well as speculation by early authors (AD 500). The effect has apparently been noticed by visual artists from the late middle ages to the present day. 相似文献

The present study examined cross-modal selective attention using a task-switching paradigm. In a series of experiments, we
presented lateralized visual and auditory stimuli simultaneously and asked participants to make a spatial decision according
to either the visual or the auditory stimulus. We observed consistent cross-modal interference in the form of a spatial congruence
effect. This effect was asymmetrical, with higher costs when responding to auditory than to visual stimuli. Furthermore, we
found stimulus-modality-shift costs, indicating a persisting attentional bias towards the attended stimulus modality. We discuss
our findings with respect to visual dominance, directed-attention accounts, and the modality-appropriateness hypothesis. 相似文献

Purpose
The objective of this study is to investigate the extent to which generational differences exist among skilled workers within a single construction trade. Although Millennials have been the focus of attention in media reports and popular management literature, little attention has been paid to empirical examinations of skilled trade workers. 相似文献999.

In masked priming tasks responses are usually faster when prime and target require identical rather than different responses. Previous research has extensively manipulated the nature and number of response-affording stimuli. However, little is known about the constraints of masked priming regarding the nature and number of response alternatives. The present study explored the limits of masked priming in a six-choice reaction time task, where responses from different fingers of both hands were required. We studied participants that were either experts for the type of response (skilled typists) or novices. Masked primes facilitated responding to targets that required the same response, responses with a different finger of the same hand, and with a homologous finger of the other hand. These effects were modulated by expertise. The results show that masked primes facilitate responding especially for experts in the S–R mapping and with increasing similarity of primed and required response. 相似文献

Memory for objects declines when people move from one location to another (the location updating effect). However, it is unclear whether this is attributable to event model updating or to task demands. The focus here was on the
degree of integration for probed-for information with the experienced environment. In prior research, the probes were verbal
labels of visual objects. Experiment 1 assessed whether this was a consequence of an item-probe mismatch, as with transfer-appropriate
processing. Visual probes were used to better coordinate what was seen with the nature of the memory probe. In Experiment
2, people received additional word pairs to remember, which were less well integrated with the environment, to assess whether
the probed-for information needed to be well integrated. The results showed location updating effects in both cases. These
data are consistent with an event cognition view that mental updating of a dynamic event disrupts memory. 相似文献
