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 ...
The interference theory is a theory regarding human memory. Interference occurs in learning. Interference occurs in learning. The notion is that memories encoded in long-term memory (LTM) are forgotten and cannot be retrieved into short-term memory (STM) because either memory could interfere with the other. [ 1 ]
These two were subsequently known as the interference theory. Therefore, associative interference is a fundamental theory which the interference theory draws upon. The essential difference between these two is time. Both retroactive and proactive interference are concerned with when the interfering elements, or memories were obtained. [4]
Another theory is that the misleading information overwrites the original information. [3] Scientists suggest that because the misleading information is the most recent, it is more easily retrieved. [4] Visual display of retroactive memory interference [further explanation needed]
The role of retrospective memory in prospective memory is suggested to be minimal, and takes the form of the information required to make plans. According to Einstein & McDaniel (1990) the retrospective memory component of the prospective remembering task refers to the ability to retain the basic information about action and context.
The difference between these two proportions is a statistic measuring one's ability to discriminate between studied and non-studied items, and has been used to represent RIF. [ 18 ] [ 19 ] Reaction time is also used to represent RIF, where slower reaction times are thought to represent more RIF due to difficulty in recognizing the studied item.
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]
Retrocausality, or backwards causation, is a concept of cause and effect in which an effect precedes its cause in time and so a later event affects an earlier one. [1] [2] In quantum physics, the distinction between cause and effect is not made at the most fundamental level and so time-symmetric systems can be viewed as causal or retrocausal.
