Lecture 14: Clinical Implications Of Memory And Forgetting Flashcards
What can infants remember?
Some implicit memories present from birth:
Relationship between movement and consequences
Infants rely on Non verbal memory techniques (visual images and motor actions)
Retention is greater and faster response with increased training, and repeated exposure to stimuli
What are the three memory systems?
Sensory memory: information goes in via sensory input, information is lost with information loss, or information can be transferred to short term memory
Short term memory: information goes in from sensory memory,
Info can also be retrieved from long term memory.
information can be rehearsed (and go back into short term memory),
information is lost via forgetting,
information is transferred to long term memory.
Long term memory: information is transferred here from short term memory
Info can be retrieved from here back to short term memory
Info can also be lost by forgetting
What is infantile amnesia?
The lack of explicit memory for events before the age of 3 years
What is the mobile conjugate reinforcement task?
This is a procedural and long term memory task based on the operant conditioning paradigm
It includes:
Baseline measure
Aqcuistion, i.e. A rapid increase in kicks
Retention i.e. Recognition and faster response
What is memory like in infancy from 0-3years?
Recognition develops first, and is better than recall at this stage
Context is important for remembering
Infant will experience neurological change with social interactions:
- due to neural connections in the cerebral cortex developing
- infant will foster self awareness, language, improved memory
- there will be a decline in infantile amnesia
What is memory like in childhood? (3-6 years)
There is a big influence on childrens episodic memory at this stage.
Children remember things they did better than things they saw
Drawing helps childrens memory
How parents talk during shared experience influences this memory
What are the significant improvement in children aged 3-6 years memories due to?
Attention
Speed and efficiency of information processing
Language and development
What is the recognition and recall like in children aged 3-6 years?
Recognition is still better than recall
Both recognition and recall improve with age
What is implict and explicit memory like in children aged 3-6 years?
Implicit memory develops first:
Children can produce behavioural changes without conscious awareness e.g. How to throw a ball
Explicit memory continues to improve: these include memories people know they have,
Facts, names and events
What is memory like in middle childhood? (Aged 6-10years)
There is a gradual increase in the understanding of memory Children can learn and use memories Learn to use external aids Rehearsal occurs Organisation Elaboration
What are some examples of emotional trauma and memory?
Recovered memories
Reporting abuse in childhood
Post traumatic stress disorder
What are some changes in memory and info processing across adult hood?
Crystallised intelligence is the knowledge and skills that are accumulated over a lifetime. This improves through adulthood
Fluid intelligence is ability to reason quickly and to think abstractly. This declines after 20s
What is memory like in adulthood? (Aged 20-60)
Information in working memory decreases
Use of memory strategies decreases
More difficulty retrieving info from long term memory
Irrelevant stimuli take up space in working memory
Compensation- need to allow more time for processing
What is attention like in adulthood?
Sustaining two complex tasks becomes harder
Focussing on relevant info becomes harder
Ability to combine pieces of visual info into a pattern declines with age
What other gains or losses in memory are experienced in adult jood
Memory skills used daily will decrease less
General, procedural and occupational knowledge are either unchanged, or may increase
There is a great increase in cognitive competence in midlife - can apply vast knowledge and life experience to problem solving
