The Role of Sensation and Perception in Everyday Life

Perception is the process of receiving and interpreting sensory information.

Balance is not a sensory modality, it is a sense that helps us maintain our equilibrium.

The absolute threshold is the minimum amount of stimulus energy that can be detected by a sensory receptor.

The difference threshold is the smallest difference between two stimuli that can be detected.

Weber's law states that the difference threshold is a constant proportion of the original stimulus.

Fechner's law states that the perceived magnitude of a stimulus is proportional to the logarithm of the stimulus intensity.

Perception is the process of organizing and interpreting sensory information.

Genetics is not a factor that influences perception.

Closure is the tendency to perceive objects as being whole and complete, even when they are incomplete.

Proximity is the tendency to perceive objects that are close together as being related.

Similarity is the tendency to perceive objects that are similar to each other as being related.

Continuity is the tendency to perceive objects that are connected by a continuous line or shape as being related.

Figure-ground is the tendency to perceive an object as being distinct from its background.

Multisensory integration is the process of combining information from different sensory modalities.

Sensation and perception help us interact with our environment by allowing us to detect and respond to changes in our environment, learn and remember information, and communicate with others.
