41) You ask your friend Drew what she had for dinner last night, and she responds that she can’t remember because her “short-term memory isn’t working.†Based on the information you have learned in your psychology course, what might you say to Drew about her short-term memory? a. You should really get your short-term memory checked out as that is not normal. b. The duration of your short-term memory is really only about 20 seconds so that is not related to your forgetting. c. Your sensory memory is likely the cause of forgetting dinner because there were too many things to encoding while eating. d. Short-term memories are often faulty and we have difficulty retaining information in this type of memory for longer than a day. 42) Results from a variety of different studies have found that ______________ is the prime culprit in forgetting information from short-term memory. a. interference b. memory span c. decay d. memory duration 43) The system of memory that can hold approximately 7 “chunks†of information for approximately 15 seconds is called a. short-term memory. b. permastore memory. c. long-term memory. d. sensory memory. 44) ______________ interference occurs when learning something new hampers earlier learning, and ______________ interference occurs when earlier learning gets in the way of new learning. a. Maintenance; elaborative b. Elaborative; maintenance c. Retroactive; proactive d. Proactive; retroactive 45) Leslie is working as a dispatcher for the police and is trying to learn the codes used to indicate various crimes in progress (e.g., 10-71 indicates shooting in progress). However, Leslie used to be a member of the RCMP and previously learned a different set of ten-codes for the same crimes (e.g., 10-53 indicates shooting in progress). Leslie finds that he is having trouble remembering the new codes for dispatching and sometimes mixes them up with his RCMP codes. Which one of the following sources of interference is most likely in this example? a. Retroactive interference b. Proactive interference c. Associative interference d. Decay interference 46) In high school, Deanna took three years of Spanish. Upon enrolling in college ten years later, she registered for a remedial French course. When required to speak in French during class discussion with her teacher and classmates, Deanna frequently responds with Spanish words instead of French words. This is one example of a. retroactive interference. b. blocking. c. proactive interference. d. decay. 47) When asked to recall single-digit numbers presented in various digit span sizes, the typical adult starts to encounter difficulty once they get past approximately ________ digits. a. 7 b. 5 c. 3 d. 4 48) Telephone numbers are exactly seven digits long likely due to recognition of a. the limited duration and span of sensory memory. b. the capacity of both echoic and iconic memory being restricted to about 7 digits. c. our short-term memory capacity being restrained to the magic number. d. serial transfer of information from short-term to long-term memory. 49) Tiffany is involved in a memory study, and is given the following list of letters to remember: APANHLNFLDCBCAB. The researcher notices that she can remember the whole series of letters, contrary to the standard seven pieces of information expected. Which of the following processes most likely explains Tiffany’s ability to remember all the letters? a. Maintenance rehearsal b. Eidetic memory c. Elaborative rehearsal d. Chunking 50) If the capacity of short-term memory is so limited, how is it that we are able to remember as much information as we do and transfer information into long-term memory? a. Long-term memory is unlimited so we can transfer information very quickly to avoid decay. b. We use processes such as chunking and rehearsal to expand the capacity of working memory. c. Visual processing of information in short-term memory allows for deep processing and transfer. d. The duration of short-term memory is unlimited so despite limited capacity, we remember this information for a long time.
