This study investigated intralimb coordination during walking in young and elderly women using the theoretical model of dynamical systems. 20 women, 10 Young (M age=24.6 yr., SD= 3.2 yr.) and 10 Elderly (M age=73.7 yr., SD=4.9 yr.), were videotaped during free speed gait and gait perturbed by an ankle weight. Two parameters, one describing the phasing relationship between segments (mean absolute relative phase) and the other the variability of this relationship (deviation in phase), were calculated from the kinematics. Two-way analysis of variance (age and weight) with repeated measures on weight indicated that during the braking period the weight increased the mean absolute relative phase between the shank and the thigh and decreased it between the foot and the shank. The Elderly women had significant smaller values for the mean absolute relative phase between the shank and the thigh during the braking period. For the same period, deviation in phase increased for the segmental 'relationship between the shank and the thigh. The findings suggest that changes in intralimb coordination take place with asymmetrical weighting and the aging process. These changes are most clearly present during the braking period.  相似文献

Traditionally, African Americans have registered lower rates of suicide than other ethnic groups. In the last 20 years this pattern has changed, particularly among young African Americans. To date, the research conducted regarding this phenomenon has been limited for a variety of reasons and previous research has been inconclusive in determining risk factors of African American suicide. The purpose of this paper is to identify risk and protective factors specific to African American suicide. To determine the factors, the 1993 National Mortality Follow-back Survey was analyzed. The risk factors identified include being under age 35, southern and northeastern residence, cocaine use, firearm presence in home, and threatening others with violence. Some of the protective factors associated with African American suicide include rural residence and educational attainment. These results provide valuable information about completed African American suicides in relation to Whites. Several of these factors are unique to African Americans.  相似文献

This article describes the results of a remedial program provided to a subject who had incurred aphasia and alexia as a result of a series of strokes. The subject was pretested individually on a battery of tests and provided a specific type of remediation by a trained tutor. Posttests were administered to determine the effects of the instructional methods. Substantial gains were noted in language and auditory comprehension with a lesser gain in word recognition. Scores on other tests remained unchanged and the subject continued to make errors indicative of alexia. The results suggest that further research of the remedial methods over a longer period of time is needed.  相似文献

Prior research has linked content analysis drawn from text narratives to psychopathology in trauma survivors. This study used a longitudinal design to determine whether linguistic elements of narrative memories of first hearing about the events of 11 September 2001 predict later post‐traumatic stress disorder (PTSD). Narratives and self‐report PTSD symptoms were collected within 1 week and again 5 months after 9/11 in 40 undergraduates. People who used more “we” words at Time 1 had fewer acute PTSD symptoms. Use of more cognitive mechanism words, more religion words, more first‐person singular pronouns, and fewer anxiety words at Time 1 were related to more chronic PTSD symptoms. Linguistic characteristics accounted for variance in chronic PTSD symptoms above and beyond acute PTSD symptoms. This study provides evidence that lasting PTSD symptoms can be predicted through language in the immediate aftermath of the trauma. Copyright © 2011 John Wiley & Sons, Ltd.  相似文献

The present study focused on the association between the particular sexual qualities midlife women desired in themselves and their husbands and the changes in sexual response they were experiencing. In a U.S. sample of 280 women participating in the ongoing Midlife Women's Health Survey, 40% reported a change in their sexual response, more often as decrements than increases, although desiring more nongenital touching was frequently noted. Respondents wanted more change in their own than in their partners' sexual qualities. In addition, the desire to change sexual qualities in oneself and in one's husband was significantly related to many changes in sexual responsivity. These findings are discussed in the context of a woman-defined sexuality at midlife.  相似文献

Dysfunctional attitudes can foreshadow depressive relapse/recurrence. Priming mood, through induction paradigms, is hypothesized to activate dysfunctional attitudes. Cognitive reactivity (CR) refers to mood-linked increases in dysfunctional attitudes after priming. Here we explored the extent to which CR as well as residual, unprimed, dysfunctional attitudes predicted depressive relapse/recurrence among depressed patients who responded to acute phase cognitive therapy (CT). Consenting adults, aged 18–70, with recurrent major depressive disorder (n = 523) participated in a two-site randomized controlled trial examining the durability of continuation phase treatments. Patients received 16–20 sessions of CT. Among the 245 incompletely remitted responders, 213 agreed to undergo a mood induction paradigm. After 8 months of continuation phase treatments, participants were followed an additional 24 months. Although the mood induction significantly lowered mood in 80% of responders, the expected CR was not evident. By contrast, higher unprimed dysfunctional attitudes following CT did predict relapse/recurrence over 20 and 32 months post-randomization. The findings of this large longitudinal study of incompletely remitted CT responders challenge the notion that it is necessary to prime mood in order to maximize dysfunctional attitudes’ prediction of relapse and/or recurrence. While findings cannot be generalized beyond CT responders, they emphasize the clinical importance of reducing dysfunctional attitudes in preventing depression.  相似文献
