Attachment theorists assume that maternal mental representations influence responsivity, which influences infant attachment security. However, primary studies do not support this mediation model. The authors tested mediation using 2 mother-infant samples and found no evidence of mediation. Therefore, the authors explored sensitivity as a moderator, studying the (a) interaction of mental representation and sensitivity as it predicts infant attachment security and (b) level of sensitivity in mothers whose infants' attachment security is either concordant or discordant with their own. The interactional analyses were not significant. But the match-mismatch data showed that when mother-infant attachment strategies were discordant, maternal sensitivity was more consistent with infant than maternal attachment strategy. These findings are congruent with an interpretation of sensitivity as a moderator that can block transmission of attachment strategy.  相似文献

The authors sought to gain further knowledge about activation of target muscles during imagery engagement in a motor task. Six hemiparetic patients and 9 healthy participants performed 3 real rises on tiptoes and then, after pausing, 3 imagery rises on tiptoes. Metronome beats guided the rate of rises and descents. Electromyographic (EMG) activity from the medial gastrocnemius and the rectus femoris muscles were monitored bilaterally throughout the performance of both tasks. In 3 healthy participants and 3 individuals with hemiparesis, EMG activity was related to the imagery task in at least 1 of the target muscles. Conversely, in the other participants, motor imagery practice was not accompanied by task-related EMG activity in the monitored muscles. In all cases, the increment in activation level during motor imagery practice was very low in comparison with that of real performance. The findings were not unequivocal; therefore, EMG activity may sometimes, but not always, be recorded during motor imagery practice both in healthy individuals and in poststroke hemiparetic participants. Further research is needed to align motor imagery practice with the objectives of motor rehabilitation.  相似文献

We examined associations between self-reported attachment anxiety and avoidance and responses to the Rorschach test. Seventy-two, nonpatient Israeli adults participated in a 2-session study. In the first session, they completed a self-report scale tapping the dimensions of attachment anxiety and attachment avoidance. In the second session, they completed the Rorschach test. The Rorschach was administered and coded according to Exner's (2001) Comprehensive System scoring. We found that self-reports of attachment anxiety were associated with Rorschach scores thought to indicate difficulties in regulating and controlling emotions and self-perceptions of being relatively helpless and unworthy. Self-reports of attachment avoidance were associated with Rorschach scores thought to reflect lack of acknowledgment of need states and maintenance of a grandiose self. We discuss the findings in terms of implicit psychodynamic processes inherent in attachment-system functioning.  相似文献

Our study examined whether perception of novel emotions, as with perception of novel objects, elicits a cardiac orientation reaction. Using a habituation-dishabituation paradigm, data from 11 adult subjects showed that orientation to both novel emotions and novel objects elicited a heart-rate deceleration. Results suggest that the orientation reaction may be an integral part of perception of emotion. Perception of emotions, therefore, is a complex, multistep process that includes an early orientation reaction.  相似文献

According to the Indian Health Service, substance abuse and Type 2 diabetes are serious problems among Native Americans. To assess substance use in a medical setting, valid screening tests are needed so the Alcohol Use Disorders Identification Test (AUDIT), a simple brief screen for excessive drinking, and the CAGE-adapted to Include Drugs (CAGE-AID) for identifying primary care patients with alcohol and drug disorders were given 50 Northern Plains American Indians with diabetes. Both are short, easy to administer, have good sensitivity and specificity, and can be easily incorporated into a medical history protocol or intake procedure. Reliability coefficients were above .90 and appeared to have sufficient concurrent and divergent validity indicated by moderate correlations with the General Well-being Schedule (rs=-.39 and -.36), the Family-Adaptation, Partnership, Growth, Affection, & Resolve (r =-.47 and -.36), and the Beck Depression Inventory-IT (r = .36 and .29).  相似文献

From 313 individuals who sustained spinal cord injuries self-reported responses were examined on their psychosocial adaptation to disability and perceived quality of life. A multidimensional scaling analysis yielded a 2-dimensional structure of adaptation. The first dimension indicated adaptive versus nonadaptive reactions. The second dimension was suggestive of denial versus realization of the affect related to the medical impairment.  相似文献
