Cards

Term

something to see what happens next.

naturally; collect information about what’s out there with NO manipulation or change.

person/event/phenomena.

Allows us to make specific
predictions about what will happen.

Definition
Variables you
select or manipulate.

Term
Double-blind study
Definition
Neither the
participant nor the experimenter in the room
knows the group/condition the participant is in
or the correct answer to the question the
participant is asked.
Term
Confounds
Definition
Uncontrolled factors that could
influence the comparison between the
experimental and control conditions.
Term
Internal Validity
Definition
Experiment measures what it
is supposed to measure (no confounds).
Term
Random Sampling
Definition
Every member of the
population has an equal chance of being picked
for the study.

Problems with Template Theory
Definition
1. Position, orientation, size.
2. Variability of patterns/styles.
3. Doesn't describe pattern differences.
4. Doesn't allow alternate descriptions.
Term

Definition
Describe a pattern by listing its parts or features.

Distinctive Features
Definition
Features that distinguish one pattern from another.

Definition
Data driven process, gather information from environment.
Term
Top Down Processing
Definition
Conceptually driven process, generates by knowledge and experience.
Term

Accuracy in recognizing a letter is higher when the letter is in a word than when it appears alone or in a nonword. Using both top/down and bottom/up processing.
Term
Sperling
Definition
Constructed the initial information processing model.
Term
Sensory Store
Definition
Brief storage for information in its original sensory form. Separate store for each sense.
Term
Filter
Definition
Attention limits the amount of information that can be recognized at one time.
Term
Selection
Definition
Attention limits the amount of recognized information that can be entered into memory.
Term

Definition
Word Superiority Effect Demo Accuracy
Term
35 Geons

Term
Selectivity
Definition
The ability to focus mental effort on a specific stimulus while excluding other stimuli.
Term
Shiftable
Definition
You can change the focus of mental effort from one stimulus to another.
Term
Divisible
Definition
Memory can be divided into parts - you can pay attention to more than one thing at the same time.
Term
Dichoctic Listening
Definition
Listening to two things at the same time.
Term
Broadbent's Filter Model
Definition
Bottleneck at recognition stage. Limited capacity perceptual channels. Hinged flap swings back and forth.
Term
Treisman's Attenuation Model
Definition
Bottleneck at recognition stage. Dials for each channel, filtering out information.
Term
Deutsch-Norman Memory Selection Model
Definition
Bottleneck after recognition. Used the shadowing experiment to demonstrate this model.
Term
Multimode Theory of Attention
Definition
Bottleneck can be moved. Experiment with shadowing and light switch demonstrated this.
Term
Capacity Model
Definition
Model of limited cognition resources.
Term
Bottleneck models
Definition
Stimuli funneled along limit capacity channels.
Term
Capacity Models
Definition
Set of cognitive processes for categorizing and recognizing stimuli.
Term
Kahneman's Model
Definition
Allocation of resources. Limited capacity is distributed to various tasks. Flexible under control. Represented as a pie.
Term
Allocation Policy of Enduring Dispositions
Definition
Reflects the rules of involuntary/automatic attention.
Term
Allocation Policy of Momentary Intentions
Definition
Reflects specific goals or objectives at a particular time.
Term
Arousal
Definition
Alertness of physiological traits.
Term
Yerkes-Dodson Curve
Definition
Arousal curve.
Term
Stroop Effect
Definition
It takes longer to name the color of the ink than the word.
Term
Automatic Skill
Definition
Occurs without intention, no conscious awareness, does not interfere with any other processes.
Term

Term
Retroactive Interference
Definition
Forgetting that occurs because of interference from material encountered after the key information was learned.
Term
Interference Theory
Definition
Forgetting occurs because other material interferes with key information.
Term
Decay Theory
Definition
Information is spontaneously lost over time, even when there is no interference.
