CHILD DEVELOPMENT PEDAGOGY

Detailed explanation-1: -The Decay theory is a theory that proposes that memory fades due to the mere passage of time. Information is therefore less available for later retrieval as time passes and memory, as well as memory strength, wears away. When an individual learns something new, a neurochemical “memory trace” is created.

Detailed explanation-2: -Trace decay theory focuses on time and the limited duration of short term memory. This theory suggests short term memory can only hold information for between 15 and 30 seconds unless it is rehearsed. After this time the information / trace decays and fades away.

Detailed explanation-3: -Rehearsal, or mentally going over a memory, can slow this process. But disuse of a trace will lead to memory decay, which will ultimately cause retrieval failure. This process begins almost immediately if the information is not used: for example, sometimes we forget a person’s name even though we have just met them.

Detailed explanation-4: -Because as we get older our synapses begin to falter and weaken, affecting the ease in which we can retrieve memories.

Detailed explanation-5: -Decay theory is a theory of forgetting. Also called trace-decay theory.
