PS260 Lecture 2: PS260 September 26, 2017 Visual (Iconic) Sensory Memory Lesson 2
Document Summary
Characteristics of iconic memory: capacity (whole vs partial report, representation of information, duration (converging operations, forgetting/loss of information. Quote of the day (cid:862)each sense organ of the body may be said to have its own memory; and these (cid:373)e(cid:373)ories are i(cid:374) a (cid:373)easure i(cid:374)depe(cid:374)de(cid:374)t of each other. (cid:863) (burnham, 1888) Iconic memory was first documented by segner (1740) a swedish scientist. Attached a glowing coal to the freely spinning wheel of a cart. Gradually increased the rate of revolution until people reported seeing a continuous circle. After calculating the time needed for a single revolution at this speed, he determined that the duration of iconic memory must be 100ms.
