Question

question 25
(q008) todd put a tiny light on one spoke of each of his bike wheels. when todd rides at night, other people see the lights as circles, and not just as a single point, until todd comes to a stop. which memory system allows for this visual effect?
o a sensory storage
o b.change blindness
o c.chunking
o d.selective attention

question 26
(q008) while preparing for his first chemistry exam, jaden is studying the elements and trying to memorize their abbreviations. on test day, he is frustrated because he studied 30 elements but can only remember the abbreviation for the last 5. this tendency to remember items at the end of a list of data is called
o a. retroactive interference.
o b. the recency effect.
o c the primacy effect.
o d. proactive interference.

question 27
(q009) florian loves the boy band directionless. when anyone asks him facts about the songs, such as how many top-ten hits they have had, dorian can tell them the correct information by accessing it from his _ memory.
o a implicit
o b.semantic
o c prospective
o d episodic

question 28
(q009) while reading about george sperlings research investigating visual sensory storage, umar is surprised to find out that one particular factor caused a significant decline in participants ability to remember what was seen. what was this factor?
o a telling the participants which of three rows of letters they would be asked to remember before the experiment
o b. a decrease in the number of items participants had to report, from 12 to 4 letters
o c a longer delay between when participants saw the three rows and when they had to report one of them
o d an increase in the amount of time participants could initially see the three rows of four letters

Explanation:

• Question 25: Sensory storage (specifically iconic memory for visual) holds sensory information briefly. The light's after - image (seen as a circle) is due to this short - term visual sensory storage. Change blindness is about failing to notice changes, chunking is organizing information, and selective attention is focusing on one thing.
• Question 26: The recency effect is the tendency to remember the last items in a list. Retroactive interference is new info interfering with old, proactive is old interfering with new, and the primacy effect is remembering the first items.
• Question 27: Semantic memory is for general knowledge (like facts about songs). Implicit is non - conscious memory (e.g., skills), prospective is remembering to do something in the future, and episodic is memory of personal events.
• Question 28: In Sperling's research, a longer delay between seeing the stimuli (rows of letters) and reporting decreased memory. Telling participants which row before (a) actually helped (as in partial report), decreasing items (b) and increasing initial viewing time (d) would not cause a significant decline as described.

Answer:

• Question 25: a. sensory storage
• Question 26: b. the recency effect
• Question 27: b. semantic
• Question 28: c. a longer delay between when participants saw the three rows and when they had to report one of them
