Horowitz and Wolfe (1998, 2003) have challenged the view that serial visual search involves memory processes that keep track of already inspected locations. The present study used a search paradigm similar to Horowitz and Wolfe's (1998), comparing a standard static search condition with a dynamic condition in which display elements changed locations randomly every 111 ms. In addition to measuring search reaction times, observers' eye movements were recorded. For target-present trials, the search rates were near-identical in the two search conditions, replicating Horowitz and Wolfe's findings. However, the number of fixations and saccade amplitude were larger in the static than in the dynamic condition, whereas fixation duration and the latency of the first saccade were longer in the dynamic condition. These results indicate that an active, memory-guided search strategy was adopted in the static condition, and a passive “sit-and-wait” strategy in the dynamic condition. 相似文献

In this study, 158 parents (79 fathers and 79 mothers) with a mean age of 38.3 yrs (SD = 8.2), estimated their own, and their children's, overall intelligence as well as their children's score on the 12 intelligence scales from the Wechsler's Intelligence Scale for Children (WISC-III). The sample included English (n = 122) and Icelandic parents (n = 36), and a comparison between them showed few differences except that Icelandic parents' estimates were lower than English parents' estimates. The results showed fathers estimated their own overall intelligence higher than mothers estimated theirs and sons were estimated higher than daughters on overall intelligence. Two factors (verbal, performance) of intelligence were identified through factor analysis of the ratings of the 12 WISC subscale score estimates. A hierarchical regression showed that these two factors explained most of the variance in the estimation of the child's overall intelligence; however, gender of child and parents' self-estimated own overall intelligence added incremental variance. 相似文献

This study uses functional magnetic resonance imaging (fMRI) to address two important gaps in our knowledge of brain functioning and violence: (1) What are the brain correlates of adults in the community who have suffered severe physical abuse early in life and who go on to perpetrate serious violence in adulthood? (2) What characterizes those who experience severe physical abuse but who refrain from serious violence? Four groups of participants recruited from the community (controls, severe physical child abuse only, serious violence only, and severely abused, seriously violent offenders) underwent fMRI while performing a visual/verbal working memory task. Violent offenders who had suffered severe child abuse show reduced right hemisphere functioning, particularly in the right temporal cortex. Abused individuals who refrain from serious violence showed relatively lower left, but higher right, activation of the superior temporal gyrus. Abused individuals, irrespective of violence status, showed reduced cortical activation during the working memory task, especially in the left hemisphere. Brain deficits were independent of IQ, history of head injury, task performance, cognitive strategy, and mental activity during the control task. Findings constitute the first fMRI study of brain dysfunction in violent offenders, and indicate that initial right hemisphere dysfunction, when combined with the effects of severe early physical abuse, predisposes to serious violence but that relatively good right hemisphere functioning protects against violence in physically abused children.

This open trial investigated the transdiagnostic effects of metacognitive therapy (MCT) in patients with severe major depressive disorder and comorbid psychiatric disorder. Ten patients were treated with MCT over 10 sessions and were assessed with measures of depression, anxiety, rumination, and metacognitions at pre- and posttreatment and at 6 months follow-up. None of the patients were diagnosed as depressed at posttreatment, and of the initial 21 total diagnoses at pretreatment only 3 diagnoses remained at postintervention. The effect sizes were large for symptoms of depression, rumination, and worry. At 6 months follow-up standardized recovery criteria on the BDI showed that 70% were recovered, 20% improved, and 10% unchanged. The results indicate that MCT was associated with high rates of transdiagnostic improvement. 相似文献

The genetics of suicide is increasingly recognized and relevant for mental health literacy, but actual beliefs may lag behind current knowledge. We examined such beliefs in student samples (total N = 686) from Estonia, Malaysia, Romania, the United Kingdom, and the United States with the Beliefs in the Inheritance of Risk Factors for Suicide Scale. Cultural effects were small, those of key demographics nil. Several facets of construct validity were demonstrated. Marked differences in perceived plausibility of evidence about the genetics of suicide according to research design, observed in all samples, may be of general interest for investigating lay theories of abnormal behavior and communicating behavioral and psychiatric genetic research findings. 相似文献
