PSYC 2700 Lecture Notes - Sensory Memory, Iconic Memory, Occipital Lobe

Lecture #2 outline: review multi-store model of memory. Sensory memory (chpt. #3 text: encoding, duration, capacity, type of code. Atkinson &amp; shiffrin (1968) (see p. 43 textbook ) Sensory memory (registers: between the environment and our other systems. How to differentiate the stores: encoding (how it gets put in the memory, duration (how long it stays in memory, capacity (how much can be put in?, type of code(s) (what kind of information) Basics of visual perception (see p. 75-81 textbook ) Perception: process of interpreting sensory information (how we interpret the information given to us) 120m rods, 7m cones, only 1m ganglion some cones have own bipolar but, many rods converge onto 1 bipolar convergence especially in 20+ degrees. How is information gathered: series of fixation-saccade cycles, saccades. Not smooth continuous variable: 25 ms 175 ms nothing seen during saccade: fixations. Eyes pause to foveate and take in information.

47. The short term memory span of 7 plus or minus 2 refers to A) the number of items that can be passed from iconic memory to STM B) the number of chunks that can be held in long term memory C) the length of time information can be held in memory D) the length of time to transfer information into long term memory E) the numbers of items lost in transfer from the sensory store to STM

Dr. Chan is interested in the study of basic processes in learning and memory. He conducts his research in a laboratory. Most likely, Dr. Chan is A) a clinical psychologist B) an educational psychologist C) a social psychologist D) a neuroscientist E) an experimental psychologist

Critics of the trichromatic theory of colour vision have indicated that this theory has a major limitation. Which of the following statements MOST accurately reflects this limitation? A) Young and von Helmholtz were incorrect in assuming that cone photoreceptors in our retina are maximally responsive to a specific wavelength of light B) The trichromatic theory cannot explain the phenomenon of visual after-effects C) Rod photoreceptors in our retina, not cones, are responsible for the neural coding of colour D) Research has determined that there are actually six types of cones in the retina, rather than three as proposed by Young and Helmholtz E) Trichromatic theory cannot explain sensory adaptation
