Cognitive Final
When presented with a list of words along a theme (e.g., "bed," "rest," "slumber," "dream," "tired"), participants often (mis)recall the theme word as part of the list (e.g., "sleep"). This procedure is commonly referred to as the
Deese-Roediger-McDermott procedure.

immediately repeating, word for word, the contents of a message.
Intrusion errors in memory are errors
in which other knowledge intrudes into the remembered event.

It has been suggested that a rigid definition for a category is not possible and that resemblance (much like a family resemblance) may be more appropriate. Why is this the case
Categorization is very often a matter of degree, not an all-or-none process.
We cannot prevent memory errors, but can they be detected?
Correctc. Currently there is no reliable detector.
Dmitri witnessed a bank robbery but now seems unable to remember what he saw. To improve Dmitri's recall, a friend hypnotizes him and asks him, while he is hypnotized, to recall the crime. Research indicates that if questioned while under hypnosis
Dmitri will not give a more accurate account of the crime than he has on other occasions.
In each trial of an experiment, participants see a warning signal and then, a half second later, see a pair of letters. The participants press one button if the letters are the same (e.g., W W ) and a different button if the letters are different (e.g., P X ). In 80% of the trials, the warning signal is identical to the letters that will be shown on that trial. The following are the warning signals and the test stimuli presented on Trial 97 of the procedure: Group 1: warning signal = L; test pair = L L Group 2: warning signal = U; test pair = L L Group 3: warning signal = +; test pair = L L In this setup we should expect the fastest responses from
Group 1 and the slowest responses from Group 2

A participant is asked to look within himself or herself and report on his or her own mental processes. This method is called
introspection
Liz is trying to remember what she read in a text chapter, but she inadvertently mixes into her recall her own assumptions about the material covered in the chapter. This is an example of
intrusion errors.
Introspection is considered the first step toward a science of cognitive psychology because
it was the first systematic attempt to observe and record the content of mental processes.
An important theme emerging from memory research is that memory connections
make memories easier to locate but can lead to intrusion errors.
The term "basic-level category" refers to the
most natural level of categorization, which is neither too specific nor too general.
A patient has suffered brain damage and, as a result, now seems to ignore all information on the left side of her world. If shown words, she reads only the right half of the word; if asked to copy a picture, she copies only the right half. This patient seems to be suffering from

A feature net is a
network of cognitive "detectors" organized in hierarchical layers.
A number of techniques have been developed that allow us to examine the moment-by-moment activity levels of specifically defined brain areas. These techniques are called
neuroimaging techniques.

only exemplar-based knowledge for the concept of octopus.
The phrase "Betsy wants to bring Jacob a present. She shook her piggy bank" is easily understood by most people because
our previous knowledge fills in the necessary details.
A participant is asked, "In the list of words I showed you earlier, was there a word that rhymed with 'lake'?" The participant is likely to be well prepared for this sort of memory test if he or she
paid attention to the sounds of the words when trying to memorize them.
Participants viewed a series of slides depicting an automobile accident. Immediately afterward, half of the participants were asked, "How fast were the cars going when they hit each other?" The other participants were asked, "How fast were the cars going when they smashed into each other?" One week later, all participants were asked more questions about the slides, including whether they had seen any broken glass in the slides. A comparison of the two groups of participants is likely to show that
participants who were asked the "smashed" question gave higher estimates of speed and were more likely to remember seeing broken glass.
An experimenter reads a list of 30 words to a group of participants at the rate of one word per second. This is immediately followed by a free-recall test. A second group of participants hears the same 30 words presented at the faster rate of two words per second. We should expect that the group hearing the slower presentation will show improved memory performance for the
pre-recency portion of the list, but there will be no impact on the recency effect.
The term "introspection" refers to the
process of each person looking within, to observe his or her own thoughts and ideas.
Top-down mechanisms suggest that
processing can be driven by knowledge and expectations.
Transcranial magnetic stimulation (TMS) uses a strong magnetic pulse to
produce a temporary disruption to the brain area, and thus brain function, where it is applied.
Capgras syndrome and other cognitive disorders are useful because they
provide information about normal cognitive functioning
Within working memory, "helpers" like the visuospatial sketchpad and phonological loop
provide short-term storage of items likely to be needed soon by the central executive.

recall
The form of brain damage identified as prosopagnosia is primarily characterized by an inability to
recognize faces.
A participant reads a list of words in which the word "elephant" appears several times. Later, the participant tachistoscopically views another list of words. When the word "elephant" appears in the second list, the participant's response rate is faster than for other words not found on the previous list. This effect is called
repetition priming.
Cognitive psychology often relies on the transcendental method, in which
researchers seek to infer the properties of unseen events on the basis of the observable effects of those events.
Memory schemas, or schemata, serve as representations of our _____ knowledge.
semantic
Which of these is LEAST important for memory acquisition?
shallow processing
You should be skeptical of "recovered" memories that were repressed because
some recovered memories turn out to be false memories suggested by therapists.
In many circumstances, participants correctly recognize that a stimulus is familiar but they are mistaken in their beliefs about where and when they encountered the stimulus. This error is referred to
source confusion
One difference between working memory and long-term memory is that
the contents of working memory depend on the content of one's current thinking, but the contents of long-term memory do not.
The "cognitive revolution" is named as such because:
the focus changed from behaviors to the processes underlying those behaviors.
Repression refers to
the removal of memories.
The strategy of maintenance rehearsal involves
the repetition of the items to be remembered, with little attention paid to what the items mean.
We can often recognize an object even if some of the object's parts are hidden from view. Evidence indicates that this recognition from partial viewing will be easiest if
we can see enough of the object to identify some of its geons.
Cognitive psychology relies on evidence from multiple domains (behavioral, neuroscience, trauma, etc.) because
we cannot see the cognitive processes directly.
You give your friend a series of lists of letters to remember. With each perfectly recalled list, you increase the list length by one or two items, until he begins to make errors. This sort of test examines
working-memory span.
