Unit 1.2: Biological Bases of Behavior ( Sensation)

Front

Sensation

Back

The process of detecting physical energy from the environment and converting it into neural signals.

Front

Transduction

Back

The conversion of physical energy (like light or sound) into electrical signals by sensory receptors.

Front

Perception

Back

The process of organizing and interpreting sensory information.

Front

Absolute Threshold

Back

The minimum level of stimulus intensity needed to detect a stimulus 50% of the time.

Front

Just-noticeable Difference

Back

The smallest change in a stimulus that can be detected.

Front

Sensory Adaptation

Back

Diminished sensitivity to a constant stimulus over time.

Front

Weber’s Law

Back

The principle that the just-noticeable difference of a stimulus is a constant proportion of the original stimulus.

Front

Synesthesia

Back

A condition in which one sense is simultaneously perceived as if by one or more additional senses.

Front

Retina

Back

The light-sensitive layer at the back of the eye where transduction occurs.

Front

Blind Spot

Back

The area of the retina without photoreceptors where the optic nerve exits the eye.
