This pilot study concerned the intelligibility of accented speech for listeners of different ages. 72 native speakers of English, representing three age groups (20-39, 40-59, 60 and older) listened to words and sentences produced by native speakers of English, Taiwanese, and Spanish. Listeners transcribed words and sentences. Listeners also rated speakers' comprehensibility, i.e., listeners' perceptions of difficulty in understanding utterances, and accentedness, i.e., how strong a speaker's foreign accent is perceived to be. On intelligibility measures, older adults had significantly greater difficulty in understanding individuals with accented speech than the other two age groups. Listeners, regardless of age, were more likely to provide correct responses if they perceived the speaker easier to understand. Ratings of comprehensibility were highly correlated with ratings of accentedness. 相似文献

The first goal of this study was to investigate sociometric status, aggression, and gender differences in children's verbalizations and cheating behavior during game playing using a fine-grained observational coding system. The second goal was to control for the effects of differential peer treatment and bias on children's behavior by observing children in a standardized procedure with unfamiliar peer confederates. Participants were 111 second-grade African American children, half average and half rejected sociometric status, half aggressive and half nonaggressive based on peer nominations, and half boys and half girls. Rejected children engaged in more cheating behavior and made more negative and argumentative verbalizations than average status children. Boys made more negative and argumentative verbalizations than girls. Aggressive children did not differ from nonaggressive children, in terms of either verbalizations or cheating behavior. 相似文献

This study compared the relative contribution of perceived family and friend support to psychological well-being and distress and examined whether family or friend support moderated the effects of stress on psychological adjustment in 338 Latino (228 Mexican American, 110 Central American) college students from a predominantly Latino university. Two multiple regressions, controlling for gender, socioeconomic level, acculturation level, and stresses (generic college, acculturative, and minority status), showed that friend support made a slightly greater contribution to well-being than family support, and friend support and not family support protected against psychological distress. Neither family nor friend support moderated the effects of stress on psychological adjustment. Further examination of these variables that assess common-specific stresses within a culture-specific theoretical framework is recommended. 相似文献

The objective of this exploratory one-group pretest-posttest study was to evaluate the nature of psychological change in inward depressed psychiatric patients attending multi-disciplinary treatment, including physical activity, designed to improve mental well-being. Female depressed psychiatric patients (n?=?51) were examined before and after this programme over a period of 3 months. The following psychological parameters were assessed: depression, anxiety, global self-esteem, and physical self-perceptions. Depressed patients demonstrated statistically significant improvements in depression, anxiety, global self-esteem and physical self-worth (t(50) ranging from -3.76 to 4.65, all p?0.007; ES ranging from 0.53 to -0.65). Changes in depression and anxiety displayed a strong negative correlation with changes in global self-esteem, and those changes are independent of the initial severity of the depressive symptoms (?F(2,48) ranging from 0.03 to 0.70, n.s.). Patients with greater improvement in physical self-perceptions reported greater improvement anxious symptoms then patients who did not improve. Consequently, within the limitations of the research design it can be concluded that the programme appeared successful in improving psychological well-being in female depressed patients. Results also provide preliminary insight into the potential role of the physical self in recovery. 相似文献

Cotton top tamarins were tested in visible and invisible displacement tasks in a method similar to that used elsewhere to
test squirrel monkeys and orangutans. All subjects performed at levels significantly above chance on visible (n=8) and invisible (n=7) displacements, wherein the tasks included tests of the perseverance error, tests of memory in double and triple displacements,
and "catch" trials that tested for the use of the experimenter's hand as a cue for the correct cup. Performance on all nine
tasks was significantly higher than chance level selection of cups, and tasks using visible displacements generated more accurate
performance than tasks using invisible displacements. Performance was not accounted for by a practice effect based on exposure
to successive tasks. Results suggest that tamarins possess stage 6 object permanence capabilities, and that in a situation
involving brief exposure to tasks and foraging opportunities, tracking objects' movements and responding more flexibly are
abilities expressed readily by the tamarins.

E. M. Elliott, Cowan, and Valle-Inclan (1998) reported a cross-modal Stroop-like interference effect in adults when an auditory distractor (a color or noncolor word) occurred simultaneously with a color patch to be named. Response times were slower with color as opposed to noncolor distractors. To distinguish two accounts of this phenomenon, we tested 4- to 11-year-olds and adults. The suppression hypothesis posits that the irrelevant word enters a phonological buffer and is injurious to color naming if the participant is unable to suppress its representation in time. The concurrent processing hypothesis states that interference occurs when the distractor and the color name are lexically accessed at the same time. Our finding that the cross-modal Stroop effect occurred in young children even with a distractor presented 500 msec in advance of the color patch favors the suppression account. Development in executive functioning may also contribute to the interference effect's becoming progressively weaker with age. 相似文献

Relations between brain electrical activity and performance on two cognitive tasks were examined in a normal population selected to be high on self-reported measures of Positive or Negative Affectivity. Twenty-five right-handed women, from an original pool of 308 college undergraduates, were the participants. EEG was recorded during baseline and during psychometrically matched spatial and verbal tasks. As predicted, participants who were high in Positive Affectivity performed equally well on the verbal and spatial tasks, while participants who were high in Negative Affectivity had spatial scores that were lower than their verbal scores. There were no group differences in baseline EEG. Both groups exhibited left central activation (i.e., alpha suppression) during the verbal and spatial tasks. When EEG data were analyzed separately for the group high in Positive Affectivity, there was evidence of parietal activation for the spatial task relative to the verbal task. The EEG data for the group high in Negative Affectivity had comparable EEG power values during verbal and spatial tasks at parietal scalp locations. These data suggest that, within a selected normal population, differences in affective style may interact with cognitive performance and with the brain electrical activity associated with that performance. 相似文献

Not letting the left leg know what the right leg is doing: limb-specific locomotor adaptation to sensory-cue conflict 总被引:1,自引:0,他引:1
We investigated the phenomenon of limb-specific locomotor adaptation in order to adjudicate between sensory-cue-conflict theory and motor-adaptation theory. The results were consistent with cue-conflict theory in demonstrating that two different leg-specific hopping aftereffects are modulated by the presence of conflicting estimates of self-motion from visual and nonvisual sources. Experiment 1 shows that leg-specific increases in forward drift during attempts to hop in place on one leg while blindfolded vary according to the relationship between visual information and motor activity during an adaptation to outdoor forward hopping. Experiment 2 shows that leg-specific changes in performance on a blindfolded hopping-to-target task are similarly modulated by the presence of cue conflict during adaptation to hopping on a treadmill. Experiment 3 shows that leg-specific aftereffects from hopping additionally produce inadvertent turning during running in place while blindfolded. The results of these experiments suggest that these leg-specific locomotor aftereffects are produced by sensory-cue conflict rather than simple motor adaptation. 相似文献
