Flashcards in Ch.7 Deck (29):
H.M.'s strange condition with being unable to learn new things taught psychology that memories are stored ??? in the brain.
normally and abnormally
Memory is the Nervous System's capacity to ? and ? skills and knowledge
The processing of information so that it can be stored
the retention of encoded representations over time
the neural process by which encoded information becomes stored in memory
the act of recalling or remembering stored info when it is needed
The multiple processes of memory can be thought of as operating over time in three phases
Strengthening of a synaptic connection, making the postsynaptic neurons more easily activated by presynaptic neurons
Long term potentiation LTP
? is distributed throughout the brain rather than confined to any specific location which is known as ?
HDAC an epigenetic mechanism involves a class of enzymes which in inhibit gene expression. Also known as a "break pad". Drugs that block HDAC increase LTP.
? happens happens each time a memory is activated and placed back in storage. It may explain why our memories for events can change over time.
? is distributed across the many brain areas, including the hippocampus, medial temporal lobes, and cortical sensory areas.
Consolidation is which phase of memory.
Long-term potentiation provides evidence for Hebb's concept that "cells that fire together wire together" T/F
The hippocampus is the only area of the brain required for memory T/F
Damage to the hippocampus results in amnesia for some but not all events
Reconsolidation offers one model for understanding why memories are not always accurate
Areas of the cortex such as the temporal lobes and sensory areas are not involved in memory
Once information is consolidated and stored, the memory will last for the animal's lifetime
Is a temporary memory system closely tied to the sensory systems
When we pay attention to something, the information passes from sensory stores to ?? ?. It briefly holds a limited amount of information in awareness.
An active processing system that keeps different types of information avail for current use
Sensory memory persists for about ? of a second and then progressively ?
The process of breaking down info into meaningful units is known as ?
When people talk about memory they are usually referring to the relatively permanent storage of information : ?? ?
The idea that the ability to recall items from a list depends on the order of presentation, with items presented early or late in the list remembered better than those in the middle
Serial position effect
?? stores info from each of the 5 senses for less than on e second enabling the brain to perceive the word as a continuous stream. Iconic memory is visual sensory memory. Echoic memory is auditory ??
Information can be held in working memory for ? to ? seconds. Working memory span is approximately seven items (plus or minus two).
