Study Notes

Attention

Attention is the cognitive process of actively processing a limited amount of information from a vast amount of information available through senses and mental processes
Attention involves both conscious and unconscious processes
Attention is used to focus on relevant information and ignore irrelevant information, maximizing efficiency of mental resources
Heightened attention increases speed and accuracy of responses to interesting stimuli

Types of Attention

Attention can be categorized into various types
- Selective attention: focusing on one stimulus while ignoring others
- Divided attention: processing multiple tasks simultaneously
- Sustained attention: maintaining focus over a prolonged period
- Alternating attention: shifting focus between different tasks

Attention Theories

Feature integration theory: first stage of preattentive processing automatically gathers information about basic features of a stimulus. The next stage is focused attention, where the features are combined to perceive the whole stimulus. The master map of locations contains locations in which features have been detected
Similarity theory: attention is not drawn to locations but to objects. Search efficiency depends on similarities between objects in the scene
Guided search theory: ranked items based on top-down and bottom-up processing of the stimulus, prioritizing higher-priority items for attention

Signal Detection and Vigilance

Signal detection theory (SDT): a framework to explain stimulus detection based on criteria. There are four possible outcomes (hits, false alarms, misses, and rejections)
Vigilance: the ability to detect stimuli over a prolonged period, influenced by time, expectations, and performance. If a stimulus outside the field of focus is detected, it takes longer.

Relevant Terminology

Orienting response: a response to a change in the environment
Channels of information: sources of information we focus on
Filtering: excluding irrelevant information to focus on something specific

Search

Search: scanning the environment for specific features; when searching, distracters can create false alarms- diverting attention away from target stimuli
Feature search: focusing on easily identifiable features
Conjunction search: more difficult, looking for a combination of features, needing focused attention

Dichotic Presentation Paradigm

Dichotic listening: a research method examining selective attention, with different messages played to each ear.
Shadowing: repeating one message from either ear back to the researcher
Participants successfully shadowed the attended channel (primary focus)
Cherry's participants could detect physical changes in the unattended channel, like the tone of the voice or a change in words
Participants are not able to process the meaningful content of unattended information

Cocktail Party Phenomenon (Effect)

Ability to focus on one channel of information amidst a noisy environment or multiple competing information sources.
Recognizing one’s name among unattended information sources.
