Exam #3 Flashcards
(160 cards)
Cognition and Psychiatric Disabilities:
- Cognitive impairment is common and may be a core feature of the disorder.
- Normal aging also potentially impairs cognition.
*Some conditions affect executive function, such as ADHD, schizophrenia, or bipolar disorder. - Depression: decision making and concentration; often only during acute phase of illness.
- ADHD: attention, executive functioning, inhibitory control deficit
- Schizophrenia: attention, memory, learning, problem solving
- OCD: difficulty switching attention, perseverating
Components of Cognition:
- Attention: effective allocation of resources; involves taking in information, interpreting, act, reassess effects
- Memory: includes basic, complex, automatic…
- Executive Function: requires a level of awareness and conscious effort, higher order skills
efficiently using cognitive resources to take in the information needed to complete a task
Attention
Automatic (auto pilot) versus Controlled Processing:
(more complex or novel tasks requiring more focused attention)
ability to sort out and focus on certain stimuli
Selective Attention
ability for multi tasking; avoid if the client has attention issues vs doing one task at a time well
Divided Attention
sustained attention; may lead to fatigue
Vigilance
Cognitive Interventions:
- Automatic Processing: simple tasks and provide opportunities for repeated practice
Selective Attention: remove irrelevant stimuli; enhance important information; use visual cues - Divided Attention: try to separate tasks; try to make 1 automatic; practice multi tasking
- Vigilance: incorporate breaks; schedule difficulty tasks during preferred time of day
- Memory: chunk relevant bits of information; create mnemonics and memory aids
- Concept Formation/Categorization: provide a cue sheet; provide real world experiences
- Problem Solving: provide and practice strategies; try to eliminate common problems
- Decision Making: limit options; teach strategies
8: Metacognition: create questions for client to ask themselves before a task; self evaluate
one of the most basic cognitive functions and used for most functioning
Memory
Types of memory:
Somatic
Episodic
Procedural
Short-term
Long-term
Working
memory for facts; tends to be created and forgotten rather easily; strategies may be used to improve retention; Deep Processing (finding meaning in facts) = improved memory
Somatic memory
memory for events that have happened to you; organized temporally
Episodic Memory
memory about how to do something; takes longer to create; more implicit (unconscious); OT often assists clients in gaining new procedural memories; repeated practice
Procedural Memory
memory that is held for only seconds or minutes; if not rehearsed, these memories are lost in 20 seconds; Miller (1956) - humans have capacity for about 7 items (plus or minus 2)
Short-term memory
memory that is the accumulation of information throughout a lifetime
Long- term memory
memory that involves “working with” short term memory while processing to complete a task
Working Memory
Executive Function: higher order cognitive skills-
- Concept Formation & Categorization
- Schemas:
- Scripts:
- Problem Solving:
- Decision Making:
- Metacognition:
concepts are the basic units of knowledge; they establish order to one’s knowledge base; may be concrete or abstract; concepts are grouped into categories; this knowledge is important for much of daily functioning; most is implicit
Concept Formation & Categorization
mental representations of concepts
Schemas
type of schema that describes a sequence of events; OT can help client create scripts to complete complex tasks
Scripts
mental process to accomplish goals; follows a predicted series of steps
Problem-solving
research shows that people use certain strategies to make decisions quickly, but these can be prone to errors (eg: it worked last time; I know a person who did that)
Decision - making
cognition about cognition; awareness of what you do and do not know; an important regulatory function to match your abilities with the task at hand
Metacognition
Assessment of Performance skills: Cognition
Test of Everyday Attention: includes 8 everyday tasks
Multiple Errands Test: measure of executive functioning that takes place in a mall
Dynamic Lowenstein OT Cognitive Assessment (LOTCA): 20 tasks to assess various cognitive functions
Executive Function Performance Test (EFPT): performance based and standardized; evolved from the Kitchen Task Assessment
Toglia’s Dynamic Interactional Approach: includes a Contextual Memory Test and Toglia Category Assessment
Allen Cognitive Level Screen (ACLS-5): leather lacing task standardized to predict functioning in DLS
Continuous Performance Test: for individuals with dementia; involves 7 everyday activities
Do-Eat: performance-based assessment for children aged 5-8; intended to administer in natural environment like a kitchen or at school, but can be adapted for the clinic
