A group of 172 mild cognitive impairment (MCI) patients and 79 healthy control participants (HC) were tested on simple reaction time (SRT). There was a significant difference between MCI and HC in mean SRT. The test could be partitioned into five segments of 16 trials each, but RT's were not always available for each partition. However, scores from each segment for 166 MCI and 41 of the HC's were available. These data showed that a significant interaction between RT‐partition and diagnostic category was the main source of the difference between groups. The interaction indicated that MCI patients performed at about the same level as HC in the initial three of the five segments of the test, but were significantly impaired during the last two segments of the 80 trials. The results were interpreted as impaired sustained attention among a large part of the MCI group, and the study shows the importance of taking into account all avaliable data resulting from this type of test.  相似文献

Across species, kin bond together to promote survival. We sought to understand the dyadic effect of exclusion by kin (as opposed to non‐kin strangers) on brain activity of the mother and her child and their subjective distress. To this end, we probed mother–child relationships with a computerized ball‐toss game Cyberball. When excluded by one another, rather than by a stranger, both mothers and children exhibited a significantly pronounced frontal P2. Moreover, upon kin rejection versus stranger rejection, both mothers and children showed incremented left frontal positive slow waves for rejection events. Children reported more distress upon exclusion than their own mothers. Similar to past work, relatively augmented negative frontal slow wave activity predicted greater self‐reported ostracism distress. This effect, generalized to the P2, was limited to mother‐ or child‐rejection by kin, with comparable magnitude of effect across kin identity (mothers vs. children). For both mothers and children, the frontal P2 peak was significantly pronounced for kin rejection versus stranger rejection. Taken together, our results document the rapid categorization of social signals as kin relevant and the specificity of early and late neural markers for predicting felt ostracism.  相似文献

We assessed the ability of the Dyadic Parent-Child Coding System to discriminate between Norwegian children with Oppositional Defiant Disorder and/or Conduct Disorder (n = 36) and community controls with no diagnosis (n = 122). All children were diagnosed by the Preschool Age Psychiatric Assessment. Results showed that a composite score of three negative parent codes—Negative Talk, Indirect Commands with No Opportunity for Compliance, and Direct Command with Compliance—as well as one child code, Command, evidenced excellent screening efficiency. Results are discussed in light of possible cultural differences in parent-child interaction and revisions of the coding system.  相似文献

International guidelines for emergency response note the importance of cultural adaptions and facilitation of local spiritual and religious healing practices when appropriate. Deciding whether traditional medicine is safe, effective and appropriate is a complex matter. This study explores the therapeutic factors of a local cleansing ritual in Northern Uganda aimed at healing former child soldiers. The components of the ritual are analysed and compared with research-based therapy for post-traumatic stress disorder. Participant observation was used during the ritual, followed by qualitative in-depth interviews and follow-up interviews over three years. The key informant is a former child soldier participating in the ritual. He was abducted and forced to commit several killings during a three-year period. The collective mobilisation of social support, the collective forgiveness and the strength of the psycho-education appear central for the effect of the ritual. In addition, the ritual draws on common therapeutic factors. The findings indicate that such a ritual involves elements that safely and effectively deal with symptoms in accordance with modern research on trauma therapy, perhaps more powerfully than Western-style therapy. Implications for collaboration with local healers in emergency settings are indicated.  相似文献

To date, only little is known about the self-directed perception and processing of subtle gaze cues in social anxiety that might however contribute to excessive feelings of being looked at by others. Using a web-based approach, participants (n=174) were asked whether or not briefly (300 ms) presented facial expressions modulated in gaze direction (0°, 2°, 4°, 6°, 8°) and valence (angry, fearful, happy, neutral) were directed at them. The results demonstrate a positive, linear relationship between self-reported social anxiety and stronger self-directed perception of others' gaze directions, particularly for negative (angry, fearful) and neutral expressions. Furthermore, faster responding was found for gaze more clearly directed at socially anxious individuals (0°, 2°, and 4°) suggesting a tendency to avoid direct gaze. In sum, the results illustrate an altered self-directed perception of subtle gaze cues. The possibly amplifying effects of social stress on biased self-directed perception of eye gaze are discussed.  相似文献

Patients with schizophrenia are at high risk of suicide. Cognitive behavior therapy (CBT) has been shown to reduce symptoms in schizophrenia. This study examines whether CBT also changes the level of suicidal ideation in patients with schizophrenia compared to a control group. Ninety ambulatory patients with symptoms of schizophrenia resistant to conventional antipsychotic medication were randomized to CBT or befriending. They were assessed using the Comprehensive Psychopathological Rating Scale, including a rating of suicidal ideation at baseline, post intervention, and after 9 months. Post-hoc analysis revealed that CBT provided significant reductions in suicidal ideation at the end of therapy, and sustained at the follow-up. Further research is required to substantiate these findings and determine the process and mechanisms through which this reduction is achieved.  相似文献

Employment of women while their children are infants has increased in the UK in the last decade. This study of 57 employed mothers of infants less than seven months old examined their retrospective reports of planning child care and their contemporaneous feelings about the child care they were using, based on qualitative interviews. Issues addressed included mothers' reasons for returning to employment at that time, their theoretical preferences among a range of child care types and providers and the process of making actual choices, including the range and types of advice received and the involvement of fathers. Mothers were also encouraged to discuss their feelings about how child care was working out once the infant was settled. Continuing concerns expressed by mothers included the importance of open communication with caregivers, their desire to keep control over infants' daily lives and upbringing, worries about infants' safety and concerns about the levels of cognitive stimulation they received.

The two evolutionary psychological hypotheses that men react more jealous than women to sexual infidelity and women react more jealous than men to emotional infidelity are currently controversial because of apparently inconsistent results. We suggest that these inconsistencies can be resolved when the two hypotheses are evaluated separately and when the underlying cognitive processes are considered. We studied jealousy with forced‐choice decisions and emotion ratings in a general population sample of 284 adults aged 20–30 years using six infidelity dilemmas and recordings of reaction times. The sex difference for emotional jealousy existed for decisions under cognitive constraint, was also evident in the decision speed, increased for faster decisions, and was stronger for participants with lower education. No evidence for a sex difference in sexual jealousy was found. Our results support the view of a specific female sensitivity to emotional infidelity that canalizes the development of an adaptive sex difference in emotional jealousy conditional to the sociocultural environment.
