We evaluate the predictions of two theories of syntactic processing complexity, dependency locality theory (DLT) and surprisal, against the Dundee Corpus, which contains the eye-tracking record of 10 participants reading 51,000 words of newspaper text. Our results show that DLT integration cost is not a significant predictor of reading times for arbitrary words in the corpus. However, DLT successfully predicts reading times for nouns. We also find evidence for integration cost effects at auxiliaries, not predicted by DLT. For surprisal, we demonstrate that an unlexicalized formulation of surprisal can predict reading times for arbitrary words in the corpus. Comparing DLT integration cost and surprisal, we find that the two measures are uncorrelated, which suggests that a complete theory will need to incorporate both aspects of processing complexity. We conclude that eye-tracking corpora, which provide reading time data for naturally occurring, contextualized sentences, can complement experimental evidence as a basis for theories of processing complexity. 相似文献

The present research examined the interplay of self-construal (independent vs. interdependent), gender group identification, and performance standards (positive vs. negative) on women’s math performance. Female participants were given a subtle self-prime prior to completing a math test under conditions where either a positive or negative group-based performance standard was rendered accessible. We report an interactive effect of self-construal, gender identification, and performance standard such that a negative (compared to a positive) standard decreased performance under interdependent self-prime (“we”) conditions, whereas the reverse pattern emerged under independent self-prime (“I”) conditions. Importantly, we observed this interplay of performance standards and self-construal only in individuals who self-identify with their gender group whereas performance outcomes of low identifiers were not affected by the experimental manipulations. 相似文献

To determine if children under 5 years were able to intercept a moving object while stepping, the authors had 9 3-year-olds hit a ball that the authors dropped from a ramp from 5 heights (1.5, 2.0, 2.5, 3.0, and 3.5 m). The statistical analysis showed that the hand movement times were similar regardless of ball rolling heights and that the hand initiation times were dependent on the ball rolling times. Children under 5 years were able to hit a moving ball, and they performed this hitting according to a temporal coupling between ball displacements and the hand contact with it. The participants' behavior of hitting while stepping supports the idea that the motor system implicitly knows what the cognitive system ignores. 相似文献

Musical ensemble performance requires the synchronization of multiple performers, resulting in sequences of chords containing multiple tones with multiple onsets. Experiments 1 and 2 investigate whether sensorimotor synchronization with chord sequences containing tone-onset asynchronies is affected by (1) the magnitude of these asynchronies (25, 30, or 50 msec) and (2) the pitch of the leading tone (high vs. low). Participants tapped a finger in synchrony with different types of chord sequences created by crossing these variables, as well as with sequences of chords containing simultaneous onsets. Results indicate that taps were drawn toward the second onset, when present, especially when it was lower in pitch than the first. Additionally, chords with nonsimultaneous onsets increased tapping variability for nonmusicians, but decreased variability for musicians. Experiment 3 measured the perceptual centers of the chords from Experiment 2, and yielded results suggesting that subjective onsets determine the temporal placement of taps during synchronization. 相似文献

The effects of torture-related injuries on long-term psychological distress in a Punjabi Sikh sample
Torture survivors often report chronic debilitating physical and psychological distress. Prior research on the relationship between physical and psychological trauma suggests that the 2 are not independent. Injury sustained during torture may increase the likelihood of subsequent distress as either a moderator or mediator. For long-term psychopathology in a sample of Punjabi Sikh survivors of human rights violations (N = 116), chronic injuries mediated the path between torture and posttraumatic stress disorder, specifically the severity of numbing symptoms. Although injuries were associated with major depression, torture was not, and injuries did not moderate the relationship between major depression and torture. Chronic injuries may represent trauma severity or persistent traumatic cues. These findings emphasize connections between physical and psychological trauma and the importance of an interdisciplinary approach to torture treatment. 相似文献

In this longitudinal study, the authors addressed intracultural variation on fathers' interactions with their 3-month-old infants, their ideas about parental care, and the timing of their children's self-recognition at the age of 18-20 months. Participants were 24 middle-class German fathers and their firstborn children. Two behavioral clusters emerged: a more proximal parenting style with extensive body contact and a more distal parenting style with extensive object stimulation. Fathers in the distal cluster had significantly more education than did fathers in the proximal cluster. Children who had experienced more distal parenting were more likely to recognize themselves in a mirror than were children with more proximal parenting. The authors discuss the results with respect to fathers' influence on child development and patterns of intracultural variation. 相似文献

We examined the vertical jump performance of each leg among 10 right-footed female ballet dancers with 1 yr. of international professional experience (quadrilles: Opera ballerinas). Their mean age was 17.5 yr. (SD=0.3). The maximal height of the unilateral jump was recorded, and muscle mass was evaluated by biphotonic absorptiometry method. Muscle mass and maximal jump height were similar for the two legs. A strong inverse relation was found between the muscle mass of the right leg (67%) and maximal jump height (r=-.81, p<.01) but not for the left leg. These results highlight a functional asymmetry and the effect of motor laterality in dance. 相似文献

We explored the functionality of interference on a forehand tennis shot among 145 6- to 10-yr.-old children using the retroactive interference procedure. First, the children were asked to execute 10 forehand drives with a small tennis racquet (prime test). They were then asked to execute 10 frontal returns (interference test). The final probe test was similar to the first test, but children executed only 3 forehand drives. Children were assessed using a developmental category for the forehand drive skill. Each developmental step reflected a common sequence of body configurations exhibited by all individuals and was evaluated point-by-point. Multivariate analysis showed that boys had higher ratings of developmental steps of coordination than girls and that the rated developmental step initially increased with age before stabilizing. The developmental steps of coordination decreased after the interference task. We also showed that interference mechanisms are operative for this gross motor skill in childhood, but no interaction was found with age and sex. Post hoc analysis showed that developmental steps were not significantly different after the interference task for the oldest children, suggesting the onset of the inhibitory process. 相似文献

The nosology of chronic depression in Diagnostic and Statistical Manual of Mental Disorders (4th ed.; DSM-IV, American Psychiatric Association, 1994) is highly complex and requires clinicians to differentiate among several chronic course subtypes. This study replicates an earlier investigation (J. McCullough et al., 2000; see record 2000-05424-007) that found few differences among Diagnostic and Statistical Manual of Mental Disorders (3rd ed. rev.; DSM-III-R; American Psychiatric Association, 1987) categories of chronic depression. In the present study, 681 outpatients with chronic major depression, double depression, recurrent major depression without full interepisode recovery, and chronic major depression superimposed on antecedent dysthymia were compared. Few differences were observed on a broad range of demographic, clinical, psychosocial, family history, and treatment response variables. The authors suggest that chronic depression should be viewed as a single, broad condition that can assume a variety of clinical course configurations. 相似文献
