Discrete task? Ex?

Short lasting/single exertion. Pressing a keyboard

Serial task? Ex?

Sequence of discrete tasks. Typing name on keyboard

Continuous task? Ex?

On going task. Walking/running

Which tasks are defined as having a distinct beginning and end? Which task does not?

Discrete, serial

Response programming? (parallel or serial?)

Preparation and initiation of movement


Response selection factors

# of stimulus response alternatives (choices), stimulus response compatability, effect of practice

Response programming factors

Response complexity, response duration

The information processing stages occur in:


Increased SR compatibility results in _________ reaction time. These changes are due to changes in _______ _______ stage.

Decreased, response selection

Increased complexity results in ________ reaction time. These changes are due to changes in the ________ ________ stage.

Increased, response programming

Decreased response duration results in _________ reaction times. These changes are due to changes in the ________ _______ stage.

Decreased, response programming

Hick's law states that reaction time will increase with increasing _________

Stimulus response alternatives

Type of reaction time for Hick's law is known as _________ reaction time


Lower limit for voluntary (simple) reaction time

100 ms

When two stimuli are presented in brief succession of each other with each stimulus requiring a separate response, one of the reaction times is affected. This is known as

Psychological refractory period

When the interval between two stimuli increases, the reaction time to the second stimulus ________.


Psychological refractory period is suggested to result from an information ___________ in the response selection/response programming stages of information processing.


Interference in information processing is taken to suggest the presence of ________ processes


Structural interference? ex?

2 physical structures required. Playing piano AND typing a letter

Capacity interference? Ex?

Limited central resources.

Juggling and riding a unicycle

Juggling and riding a unicycle (capacity interference) is produced because of limits on _________.


In the stroop task, the stimulus to respond to is the ___________ presented

Color of ink

Stroop interference is caused by _______ processes in the ________ stage of information processing

Serial, response selection

Technique that involves combining smaller units of information into larger units


Human information processing in "working memory" is known as _________ memory

Short term

Which of the following is FALSE in regard to attention?

A) non concious b) affected by arousal/anxiety/effort c) serial in nature d) limited capacity

A) non conscious

Capacity of short term memory

7 +- 2 bits

The relation between performance and arousal is best described as

Inverted u-relation

Zone of optimal functioning refers to level of arousal that ___________ performance

Maximizes performance

High levels of arousal benefits performance in ___________.

Well practiced tasks

Perceptual narrowing occurs when there is a _______ level of _______.

High, arousal

Cue utilization hypothesis suggests performance degrades at high levels of arousal due to ______.


Shifting attention cues and missing relevant information is referred to as


Costs and benefits of anticipation

Cost (incorrect anticipation): lead to increased reaction time

Benefit (correct anticipation): lead to decreased reaction time

If stimulus L is anticipated and stimulus R is presented and the incorrect response is produced. The reaction time would be predicted to

Increase variety, reduce visual precues

3 properties of a stimulus that may be predicted

Where, when, what
