quiz 2

Clive Wearing, the ex-choral director, experienced what memory problem? 

• Poor short-term memory

• Defective sensory memory

• An inability to form new long-term memories

• Both a and b are correct

The three structural components of the modal model of memory are 

• receptors, occipital lobe, temporal lobe.

• receptors, temporal lobe, frontal lobe.

• sensory memory, short-term memory, long-term memory.

• sensory memory, iconic memory, rehearsal

A property of control processes in the modal model of memory is that they 

• do not require attention.

• may differ from one task to another.

• are performed without conscious awareness.

• are difficult to modify

Information remains in sensory memory for 

• seconds or a fraction of a second.

• 15-30 seconds.

• 1-3 minutes.

• as long as it is rehearsed.

Imagine you are driving to a friend's new house. In your mind, you say the address repeatedly until you arrive. Once you arrive, you stop thinking about the address and start to think about buying a housewarming gift for your friend. To remember the address, you used a(n) _______ process in STM. 

• control

• automatic

• coding

• iconic

When light from a flashlight is moved quickly back and forth on a wall in a darkened room, it can appear to observers that there is a trail of light moving across the wall, even though physically the light is only in one place at any given time. This experience is an effect of memory that occurs because of 

• visual delay effect.

• echoic memory.

• persistence of vision.

• top-down processing.

When a sparkler is twirled rapidly, people perceive a circle of light. This occurs because 

• the trail you see is caused by sparks left behind from the sparkler.

• due to its high intensity, we see the light from the sparkler for about a second after it goes out.

• the length of iconic memory (the persistence of vision) is about one-third of a second.

• Gestalt principles work to complete the circle in our minds.

Compared to the whole-report technique, the partial-report procedure involves 

• a smaller stimulus set.

• a smaller response set.

• a smaller stimulus set and a smaller response set.

• a shorter rehearsal period.

10. Using the partial report procedure in his "letter array" experiment, Sperling was able to infer that participants initially saw ____ of the 12 letters in the display. 

• 12

• 10

• 6

• 3

11. Brief sensory memory for sound is known as 
A. iconic memory.
B. primary auditory memory.
C. echoic memory.
D. pre-perceptual auditory memory.

• iconic memory.

• primary auditory memory.

• echoic memory.

• pre-perceptual auditory memory.
