Contrasting visual working memory for verbal and non-verbal material with multivariate analysis of fMRI.
We performed a Delayed-Item-Recognition task to investigate the neural substrates of non-verbal visual working memory with event-related fMRI ('Shape task'). 25 young subjects (mean age: 24.0 years; STD=3.8 years) were instructed to study a list of either 1, 2 or 3 unnamable nonsense line drawings for 3s ('stimulus phase' or STIM). Subsequently, the screen went blank for 7s ('retention phase' o...
متن کاملVerbal and visual subsystems of working memory.
Two recent PET scanning studies have revealed the anatomical basis of the verbal and visual subsystems of working memory. The term 'working memory' refers to the system responsible for the temporary maintenance of information~nec-essary for performing such cognitive tasks as reasoning, understanding and learning. Evidence from a range of studies based on the functioning of working memory in nor...
متن کاملMotor system contributions to verbal and non-verbal working memory
Working memory (WM) involves the ability to maintain and manipulate information held in mind. Neuroimaging studies have shown that secondary motor areas activate during WM for verbal content (e.g., words or letters), in the absence of primary motor area activation. This activation pattern may reflect an inner speech mechanism supporting online phonological rehearsal. Here, we examined the causa...
متن کاملHemispheric differences in the visual analysis of the verbal and non-verbal material in children.
Five years old children, who could not read, and the same children at the aged of 7, who already knew letters, were used as subjects. A visual procedure involved presentation of single letters or a pair of letters randomly to the left or right of a central fixation point. Reaction time and number of correct identifications, showed by pressing a key, were indicators of the perception of letters....
متن کاملVerbal Memory and Working Memory Impairment in Healthy Siblings of Patients with Schizophrenia
Objective: This study aimed to investigate the verbal memory and working memory impairment in healthy siblings of patients with schizophrenia. Methods: The purpose of this study was to compare cognitive deficits in siblings of the patients with schizophrenia and control group. A total of 35 unaffected siblings of patients with schizophrenia were selected from the relatives of the pat...
