Unitary theories of memory. Unitary theories of memory are hypotheses that attempt to unify mechanisms of short-term and long-term memory. One can find early contributions to unitary memory theories in the works of John McGeoch in the 1930s and Benton Underwood, Geoffrey Keppel, and Arthur Melton in the 1950s and 1960s.
Memory consolidation is a category of processes that stabilize a memory trace after its initial acquisition. [1] A memory trace is a change in the nervous system caused by memorizing something. Consolidation is distinguished into two specific processes. The first, synaptic consolidation, which is thought to correspond to late-phase long-term ...
In psychology, a dual process theory provides an account of how thought can arise in two different ways, or as a result of two different processes. Often, the two processes consist of an implicit (automatic), unconscious process and an explicit (controlled), conscious process. Verbalized explicit processes or attitudes and actions may change ...
There is evidence that emotion enhances memory but is more specific towards arousal and valence factors. [59] To test this theory, arousal and valence were assessed for over 2,820 words. Both negative and positive stimuli were remembered higher than neutral stimuli. Arousal also did not predict recognition memory.
Organic memory. Organic memory is a discredited biological theory, held in the late nineteenth century before the rediscovery of Mendelian genetics. The theory held the controversial notion that all organic matter contains memory. [1] [2]
Recognition memory, a subcategory of explicit memory, is the ability to recognize previously encountered events, objects, or people. [1] When the previously experienced event is reexperienced, this environmental content is matched to stored memory representations, eliciting matching signals. [2] As first established by psychology experiments in ...
This theory of hierarchies has also been applied to episodic memory, as in the case of work by William Brewer on the concept of autobiographical memory. Network models. Networks of various sorts play an integral part in many theories of semantic memory. Generally speaking, a network is composed of a set of nodes connected by links.
Baddeley and Hitch's model of working memory. Baddeley's model of working memory is a model of human memory proposed by Alan Baddeley and Graham Hitch in 1974, in an attempt to present a more accurate model of primary memory (often referred to as short-term memory ). Working memory splits primary memory into multiple components, rather than ...
