Examining the hierarchical nature of scene representations in memory.

Summary of "Examining the hierarchical nature of scene representations in memory."

How are scene representations stored in memory? Researchers have often posited that scene representations have a hierarchical structure with background elements providing a scaffold for more detailed foreground elements. To further investigate scene representation and the role of background and foreground information, we introduced a new stimulus set: chimera scenes, which have the central block of objects belonging to one scene category (foreground), and the surrounding structure belonging to another (background). We used a contextual cueing paradigm and emphasized the relative importance of each by having the target placed on either the background or foreground. In a transfer block, we found that though changes to the background were highly detrimental to search performance for background targets, search performance was only slightly affected by changes to either the foreground or the background for foreground targets. These results indicate that rather than a fixed hierarchy, the structure of scene representations are more aptly captured by a parallel model that stores information flexibly.

A two-level hierarchical framework of visual short-term memory.

Over the last couple of decades, a vast amount of research has been dedicated to understanding the nature and the architecture of visual short-term memory (VSTM), the mechanism by which currently rele...

Spatial representations in the primate hippocampus, and their functions in memory and navigation.

Hippocampal spatial view neurons in primates respond to the place where a monkey is looking, with some modulation by place. In contrast, hippocampal neurons in rodents respond mainly to the place wher...

Spatial frequency supports the emergence of categorical representations in visual cortex during natural scene perception.

In navigating our environment, we rapidly process and extract meaning from visual cues. However, the relationship between visual features and categorical representations in natural scene perception is...

Understanding perirhinal contributions to perception and memory: Evidence through the lens of selective perirhinal damage.

Although a memory systems view of the medial temporal lobe (MTL) has been widely influential in understanding how memory processes are implemented, a large body of work across humans and animals has c...

How can transcranial magnetic stimulation be used to causally manipulate memory representations in the human brain?

We present a focused review on the utility of transcranial magnetic stimulation (TMS) for modulating memory, with a particular focus on multimodal approaches in which TMS is paired with neuroimaging m...

Medical and Biotech [MESH] Definitions

Works consisting of graphic representations, especially of the face, of real persons, usually posed, living or dead. They are pictures whose purpose is the portrayal of an individual or group of individuals, not pictures which merely include people as part of an event or scene. (From Thesaurus for Graphic Materials II, p540, 1995)

Type of declarative memory, consisting of personal memory in contrast to general knowledge.

A neuropsychological test designed to assess different memory functions. It may incorporate an optional cognitive exam (Brief Cognitive Status Exam) that helps to assess memory related cognitive function.

Neurological process involving the conversion of learned information into long-term memory.

Complex mental function having four distinct phases: (1) memorizing or learning, (2) retention, (3) recall, and (4) recognition. Clinically, it is usually subdivided into immediate, recent, and remote memory.
