Previous research has shown that, in a task requiring the detection of local deviations from mechanically precise timing
in music, the relative detectability of deviations in different positions is closely related to the typical expressive timing
pattern musicians produce when playing the music. This result suggests that listeners expect to hear music expressively timed
and compensate for the absence of expressive timing. Three new detection experiments shed additional light on the nature of
these timing expectations in musically trained listeners. Experiment 1 shows that repeated exposure to an atypically (but
not unmusically) timed performance leaves listeners' timing expectations unaffected. Experiment 2 demonstrates that the expectations
do not manifest themselves when listeners merely imagine the music in synchrony with a click track. Experiment 3, however,
shows that the timing expectations are fully operational when the click track is superimposed on the music. These results
reveal timing “expectations” to be an obligatory consequence of the ongoing auditory perception of musical structure.

Patients with Parkinson's disease (PD) exhibit deficits in perceptual and motor timing as well as impairments in memory and attentional processes that are related to dysfunction of dopaminergic systems in the basal ganglia. The aim of the present study was to assess the relationships existing between impaired duration judgments and defective memory and attention in PD patients. We compared time performance of medicated PD patients and control subjects on a duration reproduction task that is highly memory-dependent, and on a duration production task that could reveal effects of changes in the speed of internal time-keeping mechanisms. Each task was performed in a control counting condition and in a condition requiring divided attention between the temporal task and a concurrent reading task. Moreover, PD patients and control subjects were assessed on memory and attention using a battery of neuropsychological tests. The results revealed that in the concurrent reading condition of the reproduction task, duration judgments tended to be more variable in PD patients than in control subjects. Moreover, variability of duration reproductions was correlated with both measures of memory and of disease severity. In the concurrent reading condition of the production task, duration judgments were significantly shorter in PD patients than in control subjects, and accuracy of duration productions was correlated with scores on sub-tests of short-term memory. The findings suggest that the administration of dopamine did not entirely remove the memory deficits in PD patients. Moreover, DA treatment would have abnormally accelerated the rate of the internal clock leading to shorter duration productions in PD patients. The whole results indicate that dopamine administration in patients might have overshadowed the slowing rate of the internal clock usually reported in non medicated PD patients, without entirely restoring all of the memory functions. 相似文献

We explored the phenomenon of the transition to adulthood, focusing on how young people cope with various developmental tasks in relation to their expectations, future projects, fears and indecision in two Italian regional areas characterized by different trends in youth employability, higher educational attainment and family formation process. We measured self-perceived adulthood, self-reported satisfaction, independence, perceived support regarding personal relationships and practical and economical issues, personal projections and future life’s choices. We also explored the perception of self-fulfillment for the future concerning personal goals in life, such as in the spheres of work, studies and economic autonomy together with expectations for the quality of personal relationships. One hundred and sixty nonworking university students (M age = 22.6; SD = 2.77; range = 19–35) from the Universities of Turin and Palermo took part in this study. Sub-groups differed on self-perceived adulthood, self-reported satisfaction, independence, perceived support and self-fulfillment. Psychological and economic independence from the family of origin was most perceived by the participants from Turin who reported a higher degree of satisfaction regarding their choice of studies and their future perspective of self-fulfillment at work. Young people from Palermo highlighted personal relationships as an important source of perceived support. 相似文献

It is sometimes assumed that limits of temporal discrimination established in psychophysical tasks constrain the timing information
available for the control of action. Results from the five perceptual-motor synchronization experiments presented here argue
against this assumption. Experiment 1 demonstrates that subliminal (0.8–2%) local changes in interval duration in an otherwise
isochronous auditory sequence are rapidly compensated for in the timing of synchronized finger tapping. If this compensation
is based on perception of the highly variable synchronization error (SE) rather than of the local change in stimulus period,
then it could be based solely on SEs that exceed the temporal order threshold. However, that hypothesis is ruled out by additional
analyses of Exp. 1 and the results of Exp. 2, a combined synchronization and temporal order judgment task. Experiments 3–5
further show that three factors that affect the detectability of local deviations from stimulus isochrony do not inhibit effective
compensation for such deviations in synchronized tapping. Experiment 5, a combined synchronization and detection task, shows
directly that compensation for timing perturbations does not depend on explicit detection. Overall, the results suggest that
the automatic processes involved in the temporal control of action have access to more accurate timing information than do
the conscious decision processes of auditory temporal judgment.

In three experiments, we tested the hypothesis that activation of multiplication operand nodes (e.g., 3 and 8) can occur through presentation of their product (e.g., 24). In Experiments 1 and 2 we found activation of the operands when the product was presented as a cue in a number-matching task. In Experiment 3, activation also occurred in a parity-matching task, where the product (24) was not relevant to the parity matching on its operands (3 and 8). We concluded that bidirectional links exist among the operands and their product for multiplication problems and these links can be activated in a purely stimulus-driven manner. We suggest this may constitute the basis for the solution of simple divisions by mediation through the complementary multiplication facts. 相似文献

Neuropsychological investigation of the development of the mnesic function in mental retardation has primarily focused on evaluating short-term memory (STM). Studies have often documented a reduced verbal short-term memory span in individuals with mental retardation and with Down syndrome in particular, compared to groups of mental age-matched controls. However, recent evidence suggests that verbal short-term memory is not equally impaired in all individuals with mental retardation. Findings in children with Williams syndrome are particularly relevant in this regard. Also, data concerning STM for visual information suggest that visual-object and visual-spatial working memory may be differently compromised in people with mental retardation. In particular, individuals with Williams syndrome exhibit specific difficulties in visual-spatial but not in visual-object working memory tasks compared to typically-developing children matched for mental age. Instead, people with Down syndrome show reduced performance in both visual-spatial and visual-object tests. Taken together, these results reinforce the view that intellectual disability is not a unitary condition characterized by homogeneous slowness of cognitive development but a variety of conditions in which some cognitive functions may be more disrupted than others. The finding that the working memory deficit in individuals with Williams and Down syndrome may be qualitatively differentiated also supports the hypothesis that it is not simply a manifestation of general cognitive impairment but, rather, the expression of a specific deficit of a discrete cognitive ability. 相似文献

Recent evidence has shown that uninformative numbers can trigger attention shifts congruent with the spatial representation
of number magnitude (Fischer, Castel, Dodd, & Pratt, 2003). In the present study, three spatial-cuing experiments whose aim
was to qualify the automaticity of this numbermediated orienting are described. Experiment 1 replicated the phenomenon, showing
that uninformative numbers can evoke orienting in a simple detection task. In Experiment 2, target location was random, but
the participants were encouraged to shift attention to the left in response to large numbers and to the right in response
to small numbers. No evidence for strong automaticity was observed, since the participants’ performance was better when left-side
targets were preceded by large numbers than when they were preceded by small numbers and vice versa. Experiment 3 corroborated
this pattern by comparing gaze- and number-mediated cuing under conditions of real counterpredictiveness. The results indicate
that unlike gaze-driven orienting, number-mediated orienting is not obligatory. 相似文献
