What does redirected attention persistence refer to?

Which study showed a span of apprehension and partial report accuracy?

What allows the brain to use higher level knowledge to interpret ambiguous stimuli?

What is the technique used to study auditory sensory memory?

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).

Explore the major topics covered in Lecture 3 of the Basics of Perception course, including visual perception, pattern recognition, object recognition, agnosia, auditory perception, and the veridical nature of perception. Understand the distinction between sensation and perception and how they relate to our interaction with the physical world.
