F211. Finding and fixing attentional dysfunction in schizophrenia [PDF]
, 2018 BACKGROUND Schizophrenia is the most debilitating health problem that exists, and its cognitive impairments are the greatest predictor of disability. Since the earliest clinical descriptions of the illness, abnormalities of attention have been at the ...

Visual working memory performance in aphantasia [PDF]
Cortex, 2018 Aphantasia, i.e., the congenital inability to experience voluntary mental imagery, offers a new model for studying the functional role of mental imagery in (visual) cognition. However, until now, there have been no studies investigating whether aphantasia can be linked to specific impairments in cognitive functioning.

Stochastic sampling provides a unifying account of visual working memory limits
Proceedings of the National Academy of Sciences of the United States of America, 2020 Significance We demonstrate that three of the most prominent accounts of visual working memory in the psychology and neuroscience literature—the slots+averaging model, the variable precision model, and the population coding model—can all be expressed in ...

Similarity effects in visual working memory [PDF]
Psychonomic Bulletin & Review, 2015 Perceptual similarity is an important property of multiple stimuli. Its computation supports a wide range of cognitive functions, including reasoning, categorization, and memory recognition. It is important, therefore, to determine why previous research has found conflicting effects of inter-item similarity on visual working memory. Studies reporting a

Visual search within working memory.
Journal of Experimental Psychology: General, 2018 Attention and working memory are 2 key pillars of cognition. Despite much research, there are important aspects about the relationship between the 2 constructs that are not well understood. Here we explore the similarity in the mechanisms that select and update working memory to those that guide attention during perception, such as in visual search. We

Perceptual organization influences visual working memory [PDF]
Psychonomic Bulletin & Review, 2003 Previous studies have demonstrated that top-down factors can bias the storage of information in visual working memory. However, relatively little is known about the role that bottom-up stimulus characteristics play in visual working memory storage. In the present study, subjects performed a change detection task in which the to-be-remembered objects ...

The cognitive neuroscience of visual working memory [PDF]
, 2017 Visual working memory allows us to temporarily maintain and manipulate visual information in order to solve a task. The study of the brain mechanisms underlying this function began more than half a century ago, with Scoville and Milner’s (1957) seminal ...

Frontiers in Psychology, 2015 Previous findings suggest that visual working memory preferentially remembers angry looking faces. However, the meaning of facial actions is construed in relation to context. To date, there are no studies investigating the role of perceiver-based context

Different states of priority recruit different neural representations in visual working memory
PLoS Biology, 2020 We used functional magnetic resonance imaging (fMRI) to investigate the neural codes for representing stimulus information held in different states of priority in working memory.

Temporal dynamics of visual working memory
NeuroImage, 2016 The involvement of the human cerebellum in working memory has been well established in the last decade. However, the cerebro-cerebellar network for visual working memory is not as well defined. Our previous fMRI study showed superior and inferior cerebellar activations during a block design visual working memory task, but specific cerebellar ...
