The purposes of this study were to examine the effects of different distances and the inclusion and exclusion of acceleration and deceleration distances on the measurement of self-paced and fastest gait speeds in younger and older adults. The self-paced and fastest gait speeds of younger and older adults were measured over 4-m and 10-m walkways with the acceleration and deceleration distances included and excluded in the measuring distance. The results indicated gait speeds (both self-paced and fastest) measured over different distances were comparable only if a distance for acceleration and deceleration was excluded from the measuring distance to obtain stable and comparable gait speeds. Similar results were found for younger and older groups.  相似文献

The present study investigated whether the neural correlates for auditory feedback control of vocal pitch can be shaped by tone language experience. Event-related potentials (P2/N1) were recorded from adult native speakers of Mandarin and Cantonese who heard their voice auditory feedback shifted in pitch by −50, −100, −200, or −500 cents when they sustained the vowel sound /u/. Cantonese speakers produced larger P2 amplitudes to −200 or −500 cents stimuli than Mandarin speakers, but this language effect failed to reach significance in the case of −50 or −100 cents. Moreover, Mandarin speakers produced shorter N1 latencies over the left hemisphere than the right hemisphere, whereas Cantonese speakers did not. These findings demonstrate that neural processing of auditory pitch feedback in vocal motor control is subject to language-dependent neural plasticity, suggesting that cortical mechanisms of auditory-vocal integration can be shaped by tone language experience.  相似文献

This article presents a randomized clinical trial examining the effectiveness of a unique model of integrated care for the treatment of infant colic. Families seeking help for infant colic were randomized to either the family‐centered treatment (TX; n = 31) or standard pediatric care (SC; n = 31). All parents completed 3 days of Infant Behavior Diaries (Barr et al., 1998) and the Colic Symptom Checklist (Lester, 1997 ), Beck Depression Inventory (Beck & Steer, 1984 ), and Parenting Stress Index 3rd ed.‐SF (Abidin, 1995 ). TX families were seen three times by a pediatrician and a mental health clinician within 1, 2, and 6 weeks of baseline data. TX families received individualized treatment plans addressing problem areas of sleep, feeding, routine, and family mental health. SC families were seen only by their own healthcare provider. All families were visited at home by a research assistant to retrieve data at 2, 6, and 10 weeks after baseline. Family‐based treatment accelerated the rate of reduction of infant crying faster than did standard pediatric care. Infants in the TX group had more hours of sleep at 2 weeks posttreatment and spent less time feeding at 2, 6, and 10 weeks posttreatment than did SC infants. Results indicate that individualized family‐based treatment reduces infant colic more rapidly than does standard pediatric care.  相似文献

This study examined whether "melodic contour deafness" (insensitivity to the direction of pitch movement) in congenital amusia is associated with specific types of pitch patterns (discrete versus gliding pitches) or stimulus types (speech syllables versus complex tones). Thresholds for identification of pitch direction were obtained using discrete or gliding pitches in the syllable /ma/ or its complex tone analog, from nineteen amusics and nineteen controls, all healthy university students with Mandarin Chinese as their native language. Amusics, unlike controls, had more difficulty recognizing pitch direction in discrete than in gliding pitches, for both speech and non-speech stimuli. Also, amusic thresholds were not significantly affected by stimulus types (speech versus non-speech), whereas controls showed lower thresholds for tones than for speech. These findings help explain why amusics have greater difficulty with discrete musical pitch perception than with speech perception, in which continuously changing pitch movements are prevalent.  相似文献

已有关于信任修复的研究主要集中在正直和/或能力违背方面,关注特定信任修复策略的修复效果。本研究以修复机制划分修复策略,考察不信任的约束策略及信任的展示策略对于正直违背和善心违背的修复效果差异。以408名企业员工为被试,通过情景模拟法操作违背类型和修复策略,结果显示:组织信任的正直违背比善心违背破坏性更大,更难修复;约束策略对善心违背的修复效果显著高于对正直违背的修复效果;对正直违背来说,展示策略相对更有效。  相似文献

Source memory refers to mental processes of encoding and making attributions to the origin of information. We investigated schematic effects on source attributions of younger and older adults for different schema-based types of items, and their schema-utilization of judgments of learning (JOLs) in estimating source memory. Participants studied statements presented by two speakers either as a doctor or a lawyer: those in the schema-after-encoding condition were informed their occupation only before retrieving, while those of schema-before-encoding were presented the schematic information prior to study. Immediately after learning every item, they made judgments of the likelihood for it to be correctly attributed to the original source later. In the test, they fulfilled a task of source attributing. The results showed a two-edged effect of schemas: schema reliance improved source memory for schema-consistent items while impaired that for schema-inconsistent items, even with schematic information presented prior to encoding. Compared with younger adults, older adults benefited more from schema-based compensatory mechanisms. Both younger and older adults could make JOLs based on before-encoding schematic information, and the schema-based JOLs were more accurate in predicting source memory than JOLs made without schema support. However, even in the schema-after-encoding condition, older adults were able to make metacognitive judgments as accurately as younger adults did, though they did have great impairments in source memory itself.  相似文献
