More recently, dissociative amnesia has been defined as a dissociative disorder characterized by gaps in memory of personal information, especially of traumatic events. These gaps involve an inability to recall personal information, usually of a traumatic or stressful nature.

Which of the following is TRUE regarding sensory memory? Sensory memory is very perishable and lasts only a very short time.

The Atkinson-Shiffrin’s classic three-stage processing model of memory suggests that we (1) register fleeting sensory memories, some of which are (2) processed into on-screen and short-term memories, a tiny fraction of which are (3) encoded for long term memory and , possibly, later retrieval.

The three main stores are the sensory memory, short-term memory (STM) and long-term memory (LTM).

Two models that attempt to describe how memory works are the Multi-Store Model of Memory, developed by Atkinson & Shiffrin (1968), and the Working Memory Model of Memory, developed by Baddeley & Hitch (1974).

Atkinson-Shiffrin model

An influential theory of memory known as the multi-store model was proposed by Richard Atkinson and Richard Shiffrin in 1968. This model suggested that information exists in one of 3 states of memory: the sensory, short-term and long-term stores.

1. Theory of General Memory Process: This theory explains that the memory consists of the three cognitive processes. These are— An encoding process, a storage process and a retrieval process. Encoding is the process of receiving a sensory input and transforming it into a form, or a code which can be stored.

Tulving focused on the nature of the material that is stored in memory and distinguished between two different kinds of memory: Episodic and Semantic. Tulving believes that procedural knowledge is the first system to develop during infancy, followed by semantic knowledge and last of all – episodic memory.

Tulving’s influential theory (Tulving, 1972, 1983, 2001) proposes that human memory can be divided into at least two subtypes. Semantic memory consists of a “mental thesaurus” that provides “the memory necessary for the use of language” (Tulving, 1972 , p.
