100

Starting with the sensory input, the brain attempts to
understand/make sense.

bottom- up processing

100
Information processing guided by higher-level mental prcesses, as when we construct perceptions drawing on our experience and expections.
What is top-down processing?
100

Level of conscious awareness we are only one place at a time.

Selective inattention

100

Minimum stimulation needed to detect a particular stimulus

Absolute Threshold

100

Commercials that promote a message indirectly

Subliminal Stimuli

200
Our diminished sensitivity to constant or routine odors, sounds, and touches, to focus our attention on information changes in stimulation.
What is sensory adaptation?
200

To perceive a difference between two stimuli, they must differ by a constant proportion.

Weber's Law

200

Tendency to focus on just a particular stimulus

Selective attention

200

A hearing specialist exposes both of your ears to varying sound levels.

Audition

200

Focus on one stimulus at a time (often at the expense of others)

Selective Attention

300

Process by which our sensory receptors and nervous system recieve stimulus from our environment.

What is sensation?

300

A phenomenon where exposure to a stimulus influences a person's response to a subsequent stimulus

Priming?

300

study of the relationship between the physical characteristics of stimuli

Psychophysics

300
The minimum difference between 2 stimuli required for detection 50% of the time.
What is difference threshold?
300

Predicting how and when we detect the presence of a faint stimulus.

Signal Detection Theory

400

Mental predisposition to perceive one thing and not another.

Perceptual Set

400

A process of organizing and interpreting sensory information, enabling us to recognize meaningful objects and events

Perception

400

Diminished sensitivity to stimuli as a consequence of constant stimulation

Sensory adaptation

400

Each of your senses receives information from the environment, converts it into neural signals in a process called

Transduction

400

The two signals of Signal detection theory are?

1. Strength of the signal

2. Psychological state
