Recall bias is of particular concern in retrospective studies that use a case-control design to investigate the etiology of a disease or psychiatric condition. [ 3 ] [ 4 ] [ 5 ] For example, in studies of risk factors for breast cancer , women who have had the disease may search their memories more thoroughly than members of the unaffected ...
In psychology and cognitive science, a memory bias is a cognitive bias that either enhances or impairs the recall of a memory (either the chances that the memory will be recalled at all, or the amount of time it takes for it to be recalled, or both), or that alters the content of a reported memory. There are many types of memory bias, including:
Many researchers have attempted to identify the psychological process which creates the availability heuristic. Tversky and Kahneman argue that the number of examples recalled from memory is used to infer the frequency with which such instances occur. In an experiment to test this explanation, participants listened to lists of names containing ei
Confirmation bias (also confirmatory bias, myside bias, [a] or congeniality bias [2]) is the tendency to search for, interpret, favor, and recall information in a way that confirms or supports one's prior beliefs or values. [3]
For example, recall bias is likely to occur in cross-sectional or case-control studies where subjects are asked to recall exposure to risk factors. Subjects with the relevant condition (e.g. breast cancer) may be more likely to recall the relevant exposures that they had undergone (e.g. hormone replacement therapy) than subjects who don't have ...
The availability heuristic suggests that the likelihood of events is estimated based on how many examples of such events come to mind. Thus the familiarity heuristic shows how "bias of availability is related to the ease of recall." [1] Tversky and Kahneman created an experiment in order to test this heuristic. They devised four lists of 39 names.
Note they were asked only about the preceding week: the 15-year-olds were not asked to recall their emotions at age 12. It found evidence of a ‘rosy’ positive bias for the 12-year-olds. But this was the opposite for the 15-year-olds, who showed a 'blue' negative bias instead. [12]
Recall bias arises due to differences in the accuracy or completeness of participant recollections of past events; for example, patients cannot recall how many cigarettes they smoked last week exactly, leading to over-estimation or under-estimation.
