What is the main difference between sensation and perception?
What is the main difference between sensation and perception?
- Sensation and perception are interchangeable terms for the same process.
- Sensation involves encoding energy from the environment, while perception involves interpreting sensory information. (correct)
- Sensation and perception both involve interpreting sensory information, but in different ways.
- Sensation is the process of interpreting sensory information, while perception involves receiving energy from the environment.

Study Notes
- The eye takes in visual information during fixations.
- Measuring eye movements: Huey (1908) used a plaster of Paris cup on the cornea with cocaine to record eye movements.
- Infrared cameras are used in modern eye-tracking methods by locking onto infrared "sinks," particularly the pupil.
- Visual sensory memory, also known as Iconic Memory, is the brief memory of visual information when the stimulus is no longer present.
- Sperling's tachistoscopic study presented a grid of letters, and subjects had better recall with cued conditions (1960s).
- Iconic memory has a very brief duration and is not intuitively understood.
- A classical study on iconic memory showed a span of apprehension and partial report accuracy (Sperling's Experiment).
- Backward masking refers to a later visual stimulus affecting perception of an earlier one (Averbach and Coriell, 1961).
- The icon is not relevant to real-world perception but can be useful under certain conditions (Haber, 1983).
- Pandemonium, a model for pattern recognition, uses bottom-up and top-down processing, and its weakness is context effects (Selfridge, 1959).
- Auditory sensory memory, also known as Echoic memory, preserves auditory stimuli for a short time.
- The three-eared man procedure is a technique used to study auditory sensory memory (Darwin, Turvey, and Crowder, 1972).
- Redirected attention persistence refers to the influence of attention on memory duration, as shown in a study by Crowder and Morton (1969).
- Conceptually driven processing allows the brain to use higher level knowledge to interpret ambiguous stimuli (Warren and Warren, 1970).
