Cognitive Psych. Chapter 3: Attention

Front 1

Attention

Back 1

A concentration of mental activity that allows you to take in a limited portion of the cast stream of information available from both you sensory world and your memory

Front 2

Divided-Attention

Back 2

paying attention to two or more simultaneous messages, responding to each as needed.

Usually accuracy decreases.

Front 3

Selective-Attention

Back 3

Your mind selects stimuli based on importance and blocks the rest out.

Front 4

Dichotic Listening

Back 4

The process of listening to one thing in one ear and another completely different thing in the other.
EX. The shadowing exercise we did in class.

Front 5

Cocktail Party Effect

Back 5

Paying attention to one conversation yet you will notice your name being called somewhere above the noise of everything else.

Front 6

The Stroop Effect

Back 6

It takes longer to say the color of the text of a word then it does saying the word.

Front 7

Isolated-feature/combined feature effect

Back 7

When looking for one feature that is different from the array of irrelevant items is faster to find than finding an item with two or more features.
EX. looking for a blue X in a field of red X's and O's is easier and faster than finding a blue X in a field of blue and red X's and O's.

Front 8

Feature-present/feature-absent effect

Back 8

You can find a feature that is present in a field of objects faster than finding a object that is missing one of its features in a field of similar objects.
EX. you can find the circle with the line faster if the others don't have a line rather than looking for a circle without a line in a group that all do have lines.

Front 9

Saccadic Eye Movements

Back 9

The eye movements when we read, it brings the center of the retina into position over the words you want to read.

Front 10

Posterior Attention Network

Back 10

Located in the parietal lobe. The attention required for visual searches. Also for shifting attention and focused attention.

Front 11

Neglect

Back 11

Damage in your partial lobe where you don't notice half of your field of vision

Front 12

Anterior Attention Network

Back 12

Handles the kind of attention we use when a task features conflict. The Stroop task is an example of this attention. Inhibitory selection.

Front 13

Perceptual Selection

Back 13

decide what to attend to and what to ignore
part of the posterior

Front 14

Inhibitory selection

Back 14

Stops yourself from performing an automatic action.
Anterior part of attention

Front 15

Bottleneck Theory

Back 15

Our attention is restricted to how much can come in and out like a bottle neck.

Front 16

Feature Integration Theory

Back 16

We sometimes use distributed attention to look at all parts of the scene and process them at the same time, other times we used focused attention to process things in a scene one at a time.

Front 17

Distributed Attention

Back 17

allow you to register all the features simultaneously

Front 18

Focused Attention

Back 18

requires serial processing, and you identify one object at a time.
