• Closure

• Common fate

• Proximity

Focusing of conscious awareness on a particular stimulus and blocking out all other stimuli.

• Parallel Processing

• Absolute Threshold

• Weber's Law

• Selective attention

The process by which our sensory receptors and nervous system receive and represent stimulus energies from our environment.

• Sensation

• Perception

• Transduction

• Adaptation

The minimum difference between two stimuli required for detection 50% of the time.

• Absolute Threshold

• Difference Threshold

• Weber's Law

• Signal Detection Theory

The principle that, to be perceived as different, two stimuli must differ by a constant minimum percentage.

• Difference Threshold

• Absolute Threshold

The process of converting one form of energy into another that your brain can use.

• Adaptation

The theory predicting how and when we detect the presence of a faint stimulus amid background noise.
