Executive subprocesses in working memory: relationship to catechol-O-methyltransferase Val158Met genotype and schizophrenia.
BACKGROUND Cognitive dysfunction in the working memory domain seems to be under genetic control and is a candidate intermediate phenotype in schizophrenia. Genes that affect working memory processing may contribute to risk for schizophrenia. METHODS Working memory and attentional processing were assessed in a large and unselected sample of schizophrenic patients, their healthy siblings, and c...
متن کاملSeparable neural bases for subprocesses of recognition in working memory.
Working memory supports the recognition of objects in the environment. Memory models have postulated that recognition relies on 2 processes: assessing the degree of similarity between an external stimulus and memory representations and testing the resulting summed-similarity value against a critical level for recognition. Here, we varied the similarity between samples held in working memory and...
متن کاملWorking Memory and Executive Attention: A Revisit.
In this follow-up to my 2002 article on working memory capacity, fluid intelligence, and executive attention in Current Directions in Psychological Science, I review even more evidence supporting the idea that the ability to control one's attention (i.e., executive attention) is important to working memory and fluid intelligence. I now argue that working memory tasks reflect primarily the maint...
متن کاملWorking Memory Capacity as Executive Attention
Performance on measures of working memory (WM) capacity predicts performance on a wide range of real-world cognitive tasks. I review the idea that WM capacity (a) is separable from short-term memory, (b) is an important component of general fluid intelligence, and (c) represents a domainfree limitation in ability to control attention. Studies show that individual differences in WM capacity are ...
متن کاملFluid intelligence, working memory and executive functioning.
The causes underlying the correlation between working memory and fluid intelligence remain unknown. There are some researchers who argue that the answer can be found on the presumed executive component of working memory. However, the available empirical evidence is far from conclusive. The present study tested a sample of 229 participants. Intelligence, working memory, and executive functioning...
