A loading matrix has perfect simple structure if each row has at most one nonzero element. It is shown that if there is an orthogonal rotation of an initial loading matrix that has perfect simple structure, then orthomax rotation with 0 1 of the initial loading matrix will produce the perfect simple structure. In particular, varimax and quartimax will produce rotations with perfect simple structure whenever they exist. 相似文献

In this article we describe a child affected by right parieto-occipital lesion due to head injury. The patient showed left hemianopia, but not unilateral spatial neglect on traditional paper-and-pencil tests and on "ecological" tests. However, his parents reported frequent collisions with obstacles on the left side. A specific test was set up: The patient had to kick down skittles put on both sides of a route traced on the floor. He kicked down 89% of skittles on the right, but only 38% on the left side. These findings are discussed in light of recent theories on unilateral neglect. 相似文献

The use of a factorial survey to measure the clinical judgments of professionals is described. This design allows the researcher to partial out the effects of variables on clinical decision making while using probability sampling. Methods frequently used to study judgments are reviewed and a study of nurses' judgments about patients' confusional episodes are used to illustrate the application of the factorial survey. Acute confusion in patients is a common clinical problem for nurses working in medical-surgical units in acute care hospitals. Using the factorial survey to study a real-life problem such as confusion demonstrates how this design can be used to test judgments in complex clinical situations, to aid in concept development, and to identify consensus among professionals. 相似文献

In this study we investigated the correlation between individual linguistic ability based on performance levels and their engagement of typical and atypical language areas in the brain. Eighteen healthy subjects between 21 and 64 years participated in language ability tests, and subsequent functional MRI scans measuring brain activity in response to a sentence completion and a word fluency task. Performance in both reading and high-level language tests correlated positively with increased right-hemispheric activation in the inferior frontal gyrus (specifically Brodmann area 47), the dorsolateral prefrontal cortex (DLPFC), and the medial temporal gyrus (Brodmann area 21). In contrast, we found a negative correlation between performance and left-hemispheric DLPFC activation.Our findings indicate that the right lateral frontal and right temporal regions positively modulate aspects of language ability. 相似文献

Recent evidence suggests that decision makers in criminal procedures are susceptible to biases. We previously found support for the presence of a feature positive effect (FPE, i.e., people attach more meaning to present than to absent information) in legal-decision making. In this study, we tried to uncover the mechanisms behind the FPE. Taking a cue from the literature on situation models in language comprehension, we investigated whether a FPE manifests itself in the memorization and use of forensic evidence. Students read a case file about a fistfight as well as additional evidence. The forensic evidence was manipulated such that a FPE on guilt estimation and conviction rate could be assessed. While subjects read additional forensic evidence, their eye movements were recorded to explore the presence of FPE in online processing. Afterwards, subjects were asked to decide on the suspect's guilt. They had to recall all information they remembered from the case file and indicate which parts of information they considered relevant to this decision. The results provided evidence for the occurrence of FPE in memorization and use of information and can be explained by the theoretical construct of situation models. 相似文献

Children with early developmental delays are at heightened risk for behavior problems and comorbid psychopathology. This study
examined the trajectories of regulatory capabilities and their potentially mediating role in the development of behavior problems
for children with and without early developmental delays. A sample of 231 children comprised of 137 typically developing children
and 94 children with developmental delays were examined during mildly frustrating laboratory tasks across the preschool period
(ages 3–5). Results indicated that children with delays had greater use of maladaptive strategies (distraction, distress venting)
and lower use of adaptive strategies (constructive coping) than typically developing children. For both groups, strategies
had similar rates of growth across time; maladaptive strategies decreased and adaptive strategies increased. The intercept
of strategy use, but not the slope, was found to mediate the relation between developmental risk and externalizing behaviors.
Findings support that dysregulation, rather than the developmental risk, may be responsible for the high levels of comorbid
psychopathology. 相似文献

Shame, embarrassment, compassion, and contempt have been considered candidates for the status of basic emotions on the grounds that each has a recognisable facial expression. In two studies (N=88, N=60) on recognition of these four facial expressions, observers showed moderate agreement on the predicted emotion when assessed with forced choice (58%; 42%), but low agreement when assessed with free labelling (18%; 16%). Thus, even though some observers endorsed the predicted emotion when it was presented in a list, over 80% spontaneously interpreted these faces in a way other than the predicted emotion. 相似文献

University psychology and sociology researchers rated the likelihood they would engage in misconduct as described in 9 research scenarios, while also making moral judgments and rating the likelihood of discovery and sanctions. Multiple regression revealed significant effects across various scenarios for moral judgment as well as shame and embarrassment on reducing misconduct. The effects on misconduct of the perceived probability of sanctions were conditioned on moral judgments in some scenarios. The results have implications for how universities address the prevention, detection, and sanctioning of research misconduct. 相似文献

The current investigation sought to determine whether a standard outpatient dose of dialectical behavior therapy (DBT) skills training (2 h per week) coupled with standard CBT treatment would be sufficient to produce changes in affect regulation over the course of day hospitalization treatment. In an uncontrolled pre-post treatment design, 65 women diagnosed with anorexia nervosa or bulimia nervosa were assessed at the beginning of treatment and at the end of treatment on affect regulation. Findings indicated that participants demonstrated a significant improvement in their ability to regulate affect, suggesting that weekly DBT treatment may play an important role in producing changes in affect regulation. Secondary analyses on eating disorder outcomes revealed a significant increase in weight gain as well as a significant reduction in restriction, bingeing, purging and eating disordered cognitions. Findings are discussed in the context of clinical and treatment implications for those with severe eating disorders. 相似文献
