5 (SAT). d) inhibiting automatized responses. 11 In one experiment, participants were shown a stimulus preceded by a neutral cue, a or a misleading prime. For some participants, the primes were usually correct (high for others they were usually misleading (low validity). Which of the following was N this experiment? 32. a) Participants in the high-validity condition showed no difference between mislead trials, demonstrating that there is no cost of priming. 33. b) Participants responded faster in the primed low-validity condition than in condition, demonstrating repetition priming. 34. c) Participants responded faster in the primed high-validity condition than low-validity condition, demonstrating that expectation influences priming. 35. d) Performance in the misled condition differed between high- and low-val demonstrating that the expectation-based priming, but not repetition primin 12 Reading simple words is an example of a(n) task, and saying the color of the ink in which that word is printed is an example of a(n) task. 36. a) automatic; controlled 37. b) automatic; interference 38. c) controlled; automatic d) controlled; interference

6 13 Which of the following is a failure of selective attention? 39. a) You are in the basement ironing and you hear the phone unexpectedly ringing upstairs. 40. b) You are able to talk on the cell phone while driving. 41. c) While you are working on your problem set in the living room, you are thrown off track when your sister changes the TV channel. d) While upstairs talking to your best friend, you pretend not to hear your mother calling you to dinner. 14 In a study of spatial attention, participants were given a neutral, correct, or misleading cue about where on the screen a stimulus would appear. What is the BEST explanation for what happened on trials with misleading cues? 42. a) There were no costs because spatial attention is not a limited-capacity system. 43. b) There were no costs because although spatial attention is limited, the resources required for the task did not push its limits. 44. c) There were costs because the spotlight of attention had moved to the misled location and had to move back. d) There were costs because the eyes had moved to the misled location and had to move back.

7 15 Which of the following drivers is MOST likely to get into an accident? 45. a) a novice driver engaged in an important phone interview 46. b) an experienced driver talking on her cell phone with a good friend 47. c) a novice driver talking on her cell phone with a good friend d) an experienced driver on her cell phone engaged in an important phone interview 16 Most participants in a dichotic listening task are 48. a) unable to describe physical features like the pitch of the stimulus in the unattended channel. 49. b) unable to report the semantic content of the stimulus in the attended channel. 50. c) usually able to tell whether their native language is being spoken in the unattended channel. d) often able to notice personally relevant words like their names in the unattended channel. 17 What is the main reason why both late and early selection models can be true? 51. a) It has to do with visuospatial helper systems. 52. b) It involves neglect-like behavior in unimpaired adults.

8 53. c) The cocktail party effect no longer appears in modern life. d) It depends on how many resources are consumed by a task. 18 In the absence of attention 54. a) there is no perception. 55. b) participants still consciously perceive stimuli if the stimuli are simple enough. 56. c) participants can perceive most aspects of the world but are not influenced by what they perceive. d) stimuli may not be consciously perceived but can still have an influence on the perceiver. 19 According to most current thinking, what process is impaired (in the affected half of space) in patients with unilateral neglect syndrome? 57. a) disengaging attention from its current focus 58. b) moving attention to a new focus 59. c) locking attention on to a new focus d) holding attention on its current focus 20 Which of the following is NOT a reason why performance might improve with practice? 60. a) Practice allows us to find the best choice among competing responses.

9 61. b) With practice, individual elements of a task draw more on our resources. 62. c) Memorization is facilitated by repeated exposure. d) As each aspect of a response is automatized, more resources become available for the next aspect. 21 How does attention help solve the binding problem? 63. a) It allows the perceiver to focus on just one dimension of the input, rather than all the dimensions of that input. 64. b) It narrows the possible sources from which perceptual cues could be arriving at a given moment. 65. c) It helps the systems hold on to the goal of binding the different perceptual cues. d) It primes the different perceptual cues, so that they are easier to recognize. 22 Divided attention requires enough mental resources to attend to both tasks. These limited mental resources include all of the following EXCEPT 66. a) task-specific resources. 67. b) task-general resources that act like a bank account. 68. c) task-general tools like the response selector. d) task-general storage space like long-term memory. 23 Which of the following claims is true of the response selector? 69. a) It can select up to two responses at a time, running two

10 tasks in parallel. 70. b) It detects situations in which two conflicting responses are called for. 71. c) It inhibits habitual responses so they can be replaced with new responses. d) It can time-share between multiple tasks, launching responses as needed. 24 When listening intently to one message, you are likely to detect your name if it is spoken in a different message. This is likely to be because your name 72. a) conforms to common English phoneme patterns. 73. b) is a stimulus for which you are well primed. 74. c) is not filtered in any way by attention. d) is said loudly enough to be clearly perceived. 25 Which statement about visual attention is MOST accurate? 75. a) Stimuli that are entirely unexpected are very likely to catch our attention. 76. b) By pointing our eyes to an area, we automatically point our attention there. 77. c) By priming our detectors, we make expected stimuli more likely to be noticed and remembered. d) Attention can be directed toward specific areas of space but not specific objects.

11 26 In one experiment, participants were repeatedly shown two lines and asked to judge which line was longer. Meanwhile, black dots appeared randomly on the other parts of the screen during each trial. For some trials, the dots moved to create fins, as shown in Figure 4.3 in the textbook. Which of the following results were found? 78. a) Participants noticed immediately when the dots formed a coherent pattern. 79. b) When told after the fins trials that the dot configuration had formed a pattern and asked to select the pattern out of four choices, most participants were able to select the correct configuration change. 80. c) Most of the participants reported the top line as longer, even though the lines are equal in length. d) Only participants who were able to correctly select the pattern they had just seen reported the top line as longer.
