Summary
Feature-based attention (FBA) interferes with visual working memory (VWM) regardless of whether attention is overt or covert. Spatial attention, however, only interferes with spatial working memory, supporting distinct FBA and VWM systems.
Area of Science:
- Cognitive Psychology
- Neuroscience
- Visual Perception
Background:
- The relationship between feature-based attention (FBA) and visual working memory (VWM) is debated.
- One theory unifies FBA and VWM as attention to internal representations competing for limited resources.
- Previous research suggested only overt attention shifts, not covert shifts, interfere with VWM.
Purpose of the Study:
- To investigate the interference effects of feature versus spatial attention on VWM.
- To differentiate the impact of overt versus covert attention shifts on VWM performance.
- To test the unified theory of FBA and VWM.
Main Methods:
- A change detection paradigm was used to measure VWM performance.
- Experiments manipulated whether participants attended to object features or spatial locations.
- Attention was directed overtly (saccades) or covertly (without eye movements).
Main Results:
- Memory interference occurred when object features were attended, irrespective of overt or covert attention.
- Attending to spatial information interfered with spatial working memory, but not feature-based working memory.
- Attending to feature information did not interfere with spatial working memory.
Conclusions:
- A dissociation exists between spatial attention and VWM.
- Findings support distinct mechanisms for spatial attention and feature-based attention in relation to VWM.
- The results leave unified concepts of FBA and VWM intact, challenging a single, unified resource model.

Interference is a characteristic phenomenon exhibited by waves. When two electromagnetic waves interact with their peaks and troughs coinciding, a resulting wave with enhanced amplitude is produced. This is known as constructive interference. In this case, the two waves interacting are in phase with each other.

27.9K
RNA interference (RNAi) is a process in which a small non-coding RNA molecule blocks the post-transcriptional expression of a gene by binding to its messenger RNA (mRNA) and preventing the protein from being translated.
This process occurs naturally in cells, often through the activity of genomically-encoded microRNAs. Researchers can take advantage of this mechanism by introducing synthetic RNAs to deactivate specific genes for research or therapeutic purposes. For example, RNAi could be used...

Forgetting is a complex cognitive phenomenon influenced by several factors, among which interference and decay are particularly prominent. These processes explain why individuals often struggle to retrieve specific information from memory, leading to lapses in recall that can be observed in everyday situations.
Interference occurs when competing memories hinder the retrieval of particular information. It can be classified into two types: proactive and retroactive interference. Proactive...

01:23System of Memory
7.3K
Memory is categorized into three major systems: sensory memory, short-term memory (STM), and long-term memory (LTM). These systems differ in their capacity and the duration for which they can hold information. Sensory memory captures raw sensory input from the environment, holding it for just a few seconds or less. For example, on hearing a brief, loud sound, like a car horn honking, the sound seems to linger in the mind for a moment even after it stops. This is an instance of sensory memory...

01:24Working Memory

Working memory refers to a combination of components, including short-term memory and attention, that allow an individual to hold information temporarily as we perform cognitive tasks. It is an essential cognitive function that enables the execution of complex tasks such as problem-solving, comprehension, and reasoning. Unlike short-term memory, which simply involves the storage of information for a brief period, working memory involves the active manipulation and processing of this...

Anatomical movements refer to the various actions or motions that can be performed by the body's joints and muscles. These movements are described using specific terms to provide a standardized way of discussing and understanding the range of motion at different joints.
Here are some common anatomical movements:
Flexion and extension motions are in the sagittal (anterior–posterior) plane of motion. These movements take place at the shoulder, hip, elbow, knee, wrist,...
