Study Notes

Sensation and Perception

Sensation detects stimuli from the body or environment.
Perception organizes sensations into meaningful patterns and interpretations.
Sensations include basic experiences like hearing sounds or seeing colors.
Perceptions involve complex interpretations such as recognizing melodies or shapes.
It is difficult to completely separate sensation from perception in daily life.
Sensory processes occur simultaneously with perceptual processes as the brain receives stimuli.

Examples of Sensation vs. Perception

Visual sensation identifies black marks on a page.
Visual perception organizes these marks into readable letters and words.
Case study of Oliver Sacks: a patient with prosopagnosia could see faces but could not recognize them, illustrating the distinction between sensation (seeing) and perception (recognizing).

Sensory Laws: Thresholds and Adaptation

Sensory thresholds refer to the minimum intensity of a stimulus that can be detected.
Absolute Threshold: the minimum stimulation detectable 50% of the time for repeated stimuli.
Factors affecting absolute threshold include stimulus intensity and the individual’s physical and psychological state.
Response bias significantly influences stimulus detection readiness.

Key Definitions

Sensation: The process involving stimulation of receptor cells leading to nerve impulse transmission to the brain.
Perception: The interpretation and organization of sensory information into meaningful experiences.
Stimulus: A form of energy (light, sound) that affects sensory organs (eyes, ears).

Learning Outcomes

Understanding the meanings and differences between sensation and perception.
Recognizing factors that affect individual sensory and perceptual experiences.
Identifying principles governing sensation and perception.
