This study investigated what effect a 30% oxygen administration had on visuospatial cognitive performance and cerebral activation
and lateralization using fMRI. Eight college students were selected as the subjects for this study. An oxygen dispenser that
provided 21% and 30% oxygen at a constant rate of 8L/min was developed. In order to measure the performance level of visuospatial
cognition, two psychological tests were also developed. The experiment consisted of two runs, one for a visuospatial cognition
task with normal air (21% oxygen) and the other for a visuospatial cognition task with hyperoxic air (30% oxygen). Functional
brain images were taken with a 3T MRI using the single-shot EPI method. The results of the visuospatial behavioral analysis
reveal that accuracy rates were enhanced with 30% oxygen administration when compared to 21% oxygen. There were more activations
observed at the bilateral occipital, parietal, and frontal lobes with 30% oxygen administration. However, decreased cerebrum
lateralization was observed with 30% oxygen administration in the same regions compared with 21% oxygen administration. Thus,
it is concluded that the positive effect on the visuospatial cognitive performance level by the highly concentrated oxygen
administration resulted from an increase of cerebrum activation and a decrease of cerebrum lateralization. 相似文献

To investigate the relationships among the nursing home work environment, emotional strain, and depression in Nursing Assistants in Ohio and West Virginia, this cross-sectional study was conducted with 395 Nurse Assistants in 49 nursing homes in Ohio and West Virginia. Organizational attributes were measured independently at the individual and organizational levels. Multilevel modeling techniques were used to analyze the data. Our methods examined nursing home organizational structure (ownership type, managerial style), and work organization (emotional strain) was examined in relation to the prevalence of depression among nursing assistants. Our findings suggest workplace emotional strain and age are associated with increased odds of depression. Implications of our work include that work in nursing homes for the environment it fosters has a strong effect on emotional strain and depression among Nursing Assistants. 相似文献

Basic research has shown that behavioral persistence is often positively related to rate of reinforcement. This relation, expressed in the metaphor of behavioral momentum, has potentially important implications for clinical application. The current study examined one prediction of the momentum metaphor for automatically reinforced behavior. Participants were 3 children who had been diagnosed with an autism spectrum disorder and who engaged in stereotypic behavior maintained by automatic reinforcement. Results suggested that stereotypic behavior was more resistant to disruption following periods of access to preferred stimuli delivered on a variable-time schedule than following periods without access to preferred stimuli. The implications of these findings for the treatment of automatically reinforced behavior are discussed. 相似文献

The authors examined the relationship of authoritarian, authoritative, and permissive parenting styles and the number of years in the United States with self-perception (academic competence, morality, and self-reliance) as recalled by Korean American college students (N = 144). Authoritative parenting behaviors were most common in Korean American families, followed by authoritarian behaviors, with permissive behaviors a distant 3rd. Authoritative parenting styles and the number of years lived in the United States were predictive of higher academic competence. Authoritarian and permissive parenting styles were predictive of lower self-reliance, whereas number of years lived in the United States was related to higher self-reliance. Those findings provide partial support for generalizing D. Baumrind's (1971) model of parenting styles to Korean American families, and the findings demonstrate the importance of considering acculturation issues in parenting studies. 相似文献

This paper examines Greenwood's (2000) evidence for incompatibility between the early and later American social psychologists on the social conception of cognition, emotion, and behavior. The notion of the autonomy of the individual may offer the key to finding a degree of compatibility between them. Both generations, I argue, fundamentally accept the notion of individual persons as autonomous agents who are able to decide and choose to act and, hence, be responsible for their actions. Philosophical analysis can perhaps inform historians of social psychology on how carefully and critically to reexamine evidence for traditional claims of generational, paradigmatic, and/or foundational splits. 相似文献

The purpose of this study was to extend the validity and clinical application of the Level of Care Index (LOCI) from the Personality Assessment Inventory (PAI) in 2 independent psychiatric samples. In Study 1 (N = 201), the LOCI effectively differentiated level of care (inpatients from outpatients), and was also meaningfully associated with risk factors for psychiatric admission (e.g., suicidal ideation, self-harming behavior, previous psychiatric admission, etc.), even after controlling for other demographic variables (range of Cohen's ds = 0.57–1.00). Likewise, the LOCI also incremented other risk indicators (suicide and violence history) and relevant PAI indexes (i.e., Mean Clinical Elevation, and Suicide and Violence Potential) in predicting level of care, and explained an additional 6% to 12% of variance in the target variable. Diagnostic efficiency analyses indicated LOCI scores in the range of 15 to 18 optimize positive and negative predictive power, and classification rate. In Study 2 (N = 96), the LOCI was found to be significantly higher in those with a recent psychiatric admission within the past 6 months (d = 0.64), as compared to those without an admission. Similarly, those who were admitted for suicide risk had significantly higher mean LOCI scores as compared to those who did not (d = 0.70). The clinical implications of these findings and potential application of the LOCI are discussed. 相似文献

The purpose of the study is to investigate Parkinson disease (PD) patients’ and caregivers’ knowledge of and interest in genetic testing. Gaucher disease (GD) results from recessive mutations in glucocerebrosidase (GBA). Both heterozygote GBA carriers and GD patients are at greater risk for PD. Studies regarding knowledge of and interest in genetic testing have been limited and have not offered genetic results to participants. In this study, 353 PD patients and 180 caregivers were recruited to a PD genetic study. The association between GD, GBA mutations and PD was described to participants who reported their familiarity with genetic terms, answered questions on genetic concepts, and indicated their interest in knowing if they may have GD (two GBA mutations) and other genetic information that could impact their health. Ninety-three-percent of participants were interested in receiving GBA results; however, only 51.6 % of PD participants and 55.6 % of caregivers knew that “scientists have identified genes associated with a higher risk of developing PD.” PD patients may benefit from education and genetic counseling on the implications of genetic testing. 相似文献
