Cognitive Psychology Quiz 9
- Which of the following provides the most serious obstacle to the use of introspection as a source of scientific evidence?
A. when facts are provided by introspection, we have no way to assess the facts thenmselves, independent of the reporter's particular perspective on the facts
- The philospher Immanuel Kant based many of his arguments on transcendental inferences. A commonplace example of such an inference is:
A. a physicist inferring what the atributes of the electron must be based on visible effects caused by the electron
- Commissures, including the corpus callosum, are:
D. thick bundles of fibers that allow communication between the brain's hemispheres
- The primary motor projection area is located:
C. toward the rear of the frontal lobe
- The lateral geniculate nucleus (LGN) is:
A. a way station between the eye and the occipital cortex, located in the thalamus
- A neuron's initial, internal response to an incoming signal can vary in size. The ultimate, external response of the cell, however, does not vary in size. If the signal is sent, it is always of the same magnitude. This effect is called:
B. the all-or-none law
- Patients who have suffered damage to the occipital-parietal pathway (the 'where' system) will have difficulties with which of the following tasks?
C. reaching in the correct direction to retrieve the toothbrush
- Which of the following is NOT true for feature-based models of pattern recognition?
D. While functional and computational models have made clear the advantages of a feature-based system, we have not yet located the mechanisms in the brain that might support sucha system.
- Participants' recognition thresholds are:
A. lower for frequently seen words
- In tachitoscopic recognition, participants often make over regularization errors. These are errors in which:
D. participants are shown pattern such as 'MJLK' but perceive it as 'MILK'
- In a feature-net model, knowledge of spelling patterns:
B. in distributed across the model, and therefore the knowledge is only detectable in the overall functioning of the network
- Speed reading:
C. employs the same mechanisms as normal reading, only with less actual perception and more interference
- If one interprets dichotic-listening results in terms of 'limited processing resources,' which of the following claims fits least well with the data?
A. the detection of a message's semantic content relies on well-practiced activities, and therefore the detection places a minimal demand on our processing resources
- Priming based on specific expectations about the identity of the upcoming stimulus produces:
B. a benefit for processing if the expectations are correct but slows processing if the expectations are incorrect
- Participants are asked to listen to a tape-recorded message and to shadow the message as they hear it. Which of the following task will be easiest to combine with this shadowing task?
D. viewing a series of pictures, followed by a test measuring memory for the pictures
- It has been hypothesized that some mental resources are unitary and therefore not divisible. If two tasks both require one of these unitary resources, divided attention between these two tasks:
B. will only be possible by means of time-sharing of the resource
- Participants are asked to search for a particular target amidst a set of stimuli. On some trials two stimuli are presented, and participants must determine if one of them is the target. On other trials, eight stimuli are presented, and participants again must search for the target within the set. If participants are able to use a parallel search in this task, we would predict that:
D. response times will be the same for searching through two stimuli and for searching through eight.
- Participants are given practice in a search task with varied mapping between stimuli and responses. Under these circumstances, we would expect that after practice:
D. participants must still use a serial search to locate the target on each trial.
- Crosstalk between two tasks is defined as:
A. leakage of information about one of the tasks into the processing of the other task.
- One difference between working memory and long-term memory is that:
D. the contents of working memory depend on the content of one's current thinking; the contents of long-term memory do not
- Participants read a series of letters and then, a moment later, are asked to write down the letters they have just seen. If the letter series contains 8 to 10 letters, some errors may occur. The errors are likely to involve:
A. letters that sound like the letters they have just seen (e.g., recalling S when F was shown)
- The strategy of maintenance rehearsal involves:
D. repetition of the items to be remembered with little attention paid to what the items mean.
- In a peg-word system, participants help themselves memorize a group of items by:
B. associating each item with some part o an already memorized framework, or skeleton
