A retrospective cohort study, also called a historic cohort study, is a longitudinal cohort study used in medical and psychological research. A cohort of individuals that share a common exposure factor is compared with another group of equivalent individuals not exposed to that factor, to determine the factor's influence on the incidence of a ...
An example of Retroactive Interference would be if one was to memorize a phone number and then after a few moments memorize another phone number, practicing the second phone number more. When the recall of the first phone number is needed, the recollection will be poor because the last phone number was the item practiced the most.
Qualitative psychological research findings are not arrived at by statistical or other quantitative procedures. Quantitative psychological research findings result from mathematical modeling and statistical estimation or statistical inference. The two types of research differ in the methods employed, rather than the topics they focus on.
Some research suggests a 'blue retrospective' which also exaggerates negative emotions. Though it is a cognitive bias which distorts one's view of reality, it is suggested that rosy retrospection serves a useful purpose in increasing self-esteem and sense of well-being. [2] [3]
A retrospective study, on the other hand, looks backwards and examines exposures to suspected risk or protection factors in relation to an outcome that is established at the start of the study. Many valuable case–control studies, such as Lane and Claypon's 1926 investigation of risk factors for breast cancer, were retrospective investigations.
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 ...
Briggs's (1954) study modeled McGeoch's work on interference by setting the stage for a classic design of retroactive interference. In his study, participants were asked to learn 12 paired associates to a criterion of 100%. To ensure parsimony, these pairs can be labeled as A 1-B 1-, A 2-B 2-...A I -B I (also called AB/AC paradigm).
Longitudinal studies are often used in social-personality and clinical psychology, to study rapid fluctuations in behaviors, thoughts, and emotions from moment to moment or day to day; in developmental psychology, to study developmental trends across the life span; and in sociology, to study life events throughout lifetimes or generations; and ...
