Models of memory and theories

One may also think to the original Ebbinghaus memory experiments showing that forgetting increases for items which are studied fewer times.

Cognitive psychology 2 nd ed. Recalling a fruit from a list of other fruit, on the other hand, will prove a far more difficult task. Since a distracting task after the presentation of word pairs or large interpresentation intervals filled with distractors would be expected to displace the last few studied items from the short-term store, recency effects are still observed.

Multi Store Model of Memory

Working memory is generally used synonymously with short term memorybut this depends on how the two forms of memory are defined. Long-term memory The long-term store also long-term memory is a more or less permanent store. Advances in research and theory Vol. Another study which involved six patients who had bilateral hippocampal damage resulted in an equal impairment of recall and familiarity Because of the multiple loop theory, Working Memory has a more difficult time explaining how short term memory gets consolidated into long term memory, whereas the Unitary Theories generally explain long term memory using the same single principle that they use to explain short term memory.

Impaired familiarity with preserved recollection after anterior temporal-lobe resection that spares the hippocampus. Indeed different types of long-term memory have been identified, namely episodic memories of eventsprocedural knowledge of how to do things and semantic general knowledge. Finally, information in the short-term store does not have to be of the same modality as its sensory input.

Following its first publication, multiple extensions of the model have been put forth such as a precategorical acoustic store, [3] the search of associative memory model, [4] [5] the perturbation model, [6] [7] and permastore.

Rather than using the theory of decay for explaining how memories get forgotten, the feature model focuses on item based interference instead.

Unitary theories of memory

Because of the multiple loop theory, Working Memory has a more difficult time explaining how short term memory gets consolidated into long term memory, whereas the Unitary Theories generally explain long term memory using the same single principle that they use to explain short term memory.

Recognition memory and the medial temporal lobe: This evidence supports the theory that recollection and familiarity are two separate processes occurring in different regions of the MTL structures.

The patterns of the activations that occur give rise to cognitive representations such as memory and knowledge. Recollection and familiarity in dense hippocampal amnesia: This reliance on recollection for normal rats was most likely due to the fact that the rats were exposed to the same odors and mediums for multiple pairings, providing a more concrete association with the stimulus.

Memory Retrieval This refers to getting information out storage. For example, why are we able to recall information which we did not rehearse e.

Unitary theories of memory

Shallow processing results in a fragile memory trace can be compared with the short term memory of the Atkinson-Shiffrin Model and deeper processing results in a more durable memory trace long term memory. Asymmetrical curves reflect strong memories and curvilinearity reflects weak memories.

The Duplex model of memory integrates these three models whereby the basic assumption is that memory can be understood in terms of Short Term and Long Term functions. This eclectic approach is seen in a framework of long-term memory proposed by Lefrancois (). Memory Psychology Memory Psychology.

10 Influential Memory Theories and Studies in Psychology. Baddeley and Hitch developed another model of short-term memory which is called working memory. The distinction between short-term memory and working memory is that short-term memory is frequently used interchangeably with working memory however the two of them should be used separately.

1. Multi-Store Model (Atkinson & Shiffrin, ) An influential theory of memory known as the multi-store model was proposed by Richard Atkinson and Richard Shiffrin in This model suggested that information exists in one of 3 states of memory: the sensory, short-term and long-term stores.

Two Theories for Memory: The Multi-Store Memory Model: Sensory Stores Information directly received from sensory input, i.e. sight/hearing. Attention determines which parts are transferred to Short Term Storage Short Term Stores (STS) Memory with highly limited capacity (10 seconds) Information is forgotten if not rehearsed/ encoded into long term memory.
