Pack 2 definitions Flashcards
Outline the flow diagram of memory
Memory Short term (Sensory >1sec + working >1min) + Long term (Explicit + implicit)
Processes of memory
Encoding storage and retrieval
Define encoding
Transforming external events or internal thoughts into memory
How are long term memories encoded
PEECLS
Perception, encoding, engram, consolidation, long term potentiation, storage
Depths of encoding
Semantic (meaning) phonemic (sounds like) and structural (letters/physical)
Define storage
Retaining information in memory
STM
Short term memory
Sensory and working
Types of short term memory
Iconic (0.5sec) eyes
Echoic (3-4sec) ears
Haptic (<1 sec) hands
Working memory definition
temporary capacity to hold information, i.e. chunking (instead of 0275059117, 027-505-9117)
Types of working memory
Auditory rehearsal, visual spatial sketchpad, central executive
LTM
Long term memory
Types of long term memory
Explicit (semantic and episodic)
Implicit (procedural, priming, conditioning, habituation)
Difference between explicit and implicit
Explicit, facts events beliefs, we recall intentionally
Implicit, knowing how, unconscious
Procedural
How to do things i.e. motor skills
Priming
Identify stimulus easier 2nd time
Conditioning/habituation
Forms of unconscious learning
How does long term memory oocur?
Neural pathway change, engram
Where are memories about emotions stored
Amygdala
Where are habits formed
Striatum
Where are semantic memories/ consolidation of memories
Hippocampus
Where are procedural memories stored
Cerebellum
Define retrieval
Bringing to mind from memory
Recall
Generate a mental representation of information that is absent
Recognition
Noticing stimuli is like a prior one
Reconstruction
Piecing together memories based on information that is recalled
Factors that effect LTM retrieval
Stress/memory
Flashbulb memories
Serial position
Context
Stress & memory
Too stressed won’t remember, not stressed enough, won’t remember
Flashbulb memories & retrieval
Detailed memories of dramatic events, emotionally charged, learn about events after they happen
Serial position and retrieval
Primary effect - First items recalled better
Recency effect - last items recalled better
Context and retrieval
Environment & state cues to recall memories
Causes of forgetting
Failure to encode Decay Interference Retrieval failure Motivated forgetting
Failure to encode
Does not get enough attention/rehearsal to go into LTM
Decay
Memory fades over time
Interference
Confusion with similar memories, competing information etc
Retrieval failure
Inability to find necessary retrieval cue
Motivated forgetting
Forgot what don’t want to think about
trauma etc
Infantile amnesia
Lack of explicit memory for first 3 years of life
Memory at birth
Developments in perception, neurology and cognitive processes, including memory
Memory in infancy (0-1yrs)
Implicit memory
Object permanence
Recognition not recall
Memory in toddlers (2-3yrs)
Implicit Semantic and episodic memory forming
Recall names objects and places
Language
Mainly recognition over recall
Memory in early childhood (3-6yrs)
Significant improvement due to attention, language, information processing etc
Remember things they did better than things they saw
Memory in middle childhood (6-10yrs)
Own understanding of memory
Mnemonics
External aids
Rehearsal
Define mnemonics
Devices to assist memory
Causes of memory issues in childhood
ADHD Epilepsy Trauma FASD Cerebrovascular events
Misinformation effect
Misleading information incorporated after the event
False memory
Recollections that feel real but are not
Crystallized intelligence
Skills depending on knowledge, judgment and social skills, semantic and procedural memories
Fluid intelligence
Information processing skills
Speed of info analysis
Working memory capacity
Memory in adults (20-60)
Peaks in 20s Working memory diminishes Retrieval difficulty Multitasking is difficult Focusing is difficult Need more time for processing
