A hallmark of both visual attention and working memory is their severe capacity limit: People can attentively track only about four objects in a multiple object tracking (MOT) task and can hold only up to four objects in visual working memory (VWM). It has been proposed that attention underlies the capacity limit of VWM. We tested this hypothesis by determining the effect of varying the load of...
Verbal working memory (VWM), the ability to maintain and manipulate representations of speech sounds over short periods, is held by some influential models to be independent from the systems responsible for language production and comprehension [e.g., Baddeley, A. D. Working memory, thought, and action. New York, NY: Oxford University Press, 2007]. We explore the alternative hypothesis that mai...
Research has demonstrated navigational aids impair spatial memory, but has not considered important spatial cognitive concepts. For example, impairment may stem from spatial perspective switches between route-based aids and survey-based memory assessments. Further, the verbal format of aid instructions may selectively interfere with verbal working memory (VWM). To address these potential explan...
Neuroimaging studies of normal subjects and studies of patients with focal lesions implicate regions of parietal cortex in verbal working memory (VWM), yet the precise role of parietal cortex in VWM remains unclear. Some evidence (; ) suggests that the parietal cortex mediates the storage of verbal information, but these studies and most previous ones included encoding and retrieval processes a...
Typing Chinese words on a computer can be carried out with a phonology-based or an orthography-based method. Phonological typing constantly engages typists’ verbal working memory (VWM), while orthographic typing engages their visual-spatial working memory (VSWM). Accordingly, habitual phonological typists would develop a better VWM capacity, while habitual orthographic typists would have a bett...
This article reviews research that has investigated the role of verbal working memory (VWM) in sentence comprehension in both typical and atypical developmental populations. Two theoretical approaches that specify different roles for VWM in sentence comprehension are considered: (i) capacity-limit approaches, which treat VWM as a theoretical primitive that causally constrains language processin...
Poor sleep quality negatively affects memory performance, and working memory in particular. We investigated sleep habits related to sleep quality including sleep duration, daytime nap duration, nap frequency, and dream content recall frequency (DCRF). Declarative working memory can be subdivided into verbal working memory (VWM) and visuospatial working memory (VSWM). We hypothesized that sleep ...
The impact of monetary reward on verbal working memory (vWM) and verbal long-term memory (vLTM) was evaluated in 50 patients with schizophrenia spectrum disorders and 52 matched healthy participants. This research was motivated by the observations that negative symptoms in schizophrenia are associated with reduced drive and that patients with these symptoms exhibit greater mnemonic impairments....
UNLABELLED BACKGROUND/STUDY CONTEXT: Visual working memory (VWM) has been shown to be particularly age sensitive. Determining which measures share variance with this cognitive ability in older adults may help to elucidate the key factors underlying the effects of aging. METHODS Predictors of VWM (measured by a modified Visual Patterns Test) were investigated in a subsample (N = 44, mean age =...
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 patients refe...
