This study examined developmental trends in object and spatial working memory (WM) using heart rate (HR) to provide an index of covert cognitive processes. Participants in 4 age groups (6-7, 9-10, 11-12, 18-26, n=20 each) performed object and spatial WM tasks, in which each trial was followed by feedback. Spatial WM task performance reached adult levels before object WM task performance. The differential developmental trends for object and spatial WM found in this study are taken to suggest that these WM components are separable. Negative performance feedback elicited HR slowing that was more pronounced for adults than for children. The development of performance monitoring as indexed by covert HR slowing following performance feedback contributes to WM performance.  相似文献

Comparisons of the WISC-R and PPVT-R were made with 37 students (25 boys, 12 girls). Pearson product moments (r) and two-tail f-tests were employed in the data analysis. The sample ranged in age from 6-2 to 14-6, with a mean age of 10-1, and SD=2.6. There were no significant differences between the WISC-R IQs and PPVT-R standard scores. The PPVT-R did not correlate significantly with the WISC-R IQ scales.  相似文献

Vitamin B12 deficiency can present with neurologic and psychiatric symptoms without macrocytic anaemia. We describe a case of late-onset cobalamin C deficiency which typically presents with normal serum vitamin B12 concentrations, posing an additional diagnostic challenge. A 23-year-old woman with decreased muscle strength and hallucinations was diagnosed with ‘catatonic depression’ and admitted to a residential mental health facility. She was referred to our hospital for further investigation 3 months later. Heteroanamnesis revealed that the symptoms had been evolving progressively over several months. Magnetic resonance imaging (MRI) of the brain showed diffuse symmetrical white matter lesions in both hemispheres. Routine laboratory tests including vitamin B12 and folic acid were normal except for a slight normocytic, normochromic anaemia. Over the next 6 weeks her symptoms deteriorated, and she became unresponsive to stimuli. A new MRI scan showed progression of the white matter lesions. The neurologist requested plasma homocysteine (Hcys) which was more than 8 times the upper limit of normal. Further testing revealed increased methylmalonic acid and the patient was diagnosed with adult-onset cobalamin C deficiency. This case illustrates that Hcys and/or methylmalonic acid should be determined in patients presenting with neuropsychiatric symptoms suggestive of vitamin B12 deficiency with a normal serum vitamin B12 to rule out a late-onset cobalamin C deficiency.  相似文献

In June 2015, Melissa Harris-Perry infamously analogized the possibility of trans-Black identity to the reality of transgender identity. Such analogies happen often and are used mostly for the benefit of learning about a less familiar form of identity. Building from a recent article by Suthakaranm, Filsinger, and White (2013 Suthakaran, V., Filsinger, K., &; White, B. (2013). Using analogies as an experiential learning technique in multicultural education. Multicultural Perspectives, 15(2), 9297.[Taylor &; Francis Online] [Google Scholar]) that presented a compelling argument for the use of analogies as an experiential learning tool in multicultural education, we advance the conversation by distinguishing a particular form of analogies: identity analogies. We explore the benefits and challenges of utilizing identity analogies as a tool for multicultural educators within U.S. higher education.  相似文献
