FASD/ Cognition/ Perception
Term | Definition |
---|---|
prevalence of FASD | 4% of Canadians 1.4-4.4% of Albertans Higher in special populations like northern communities, correctional systems Leading preventable birth defect |
diagnosis of FASD | No biological test Diagnosis of exclusion: 1. Prove pervasive brain dysfunction (2SD+ below mean in 3+ brain areas) 2. Rule out any other causes for dysfunction |
neurodevelopmental domains of FASD | Motor Neuro-anatomy Memory Academic achievement Language Cognition Attention Executive function Affect regulation Social skills |
motor domain testing in FASD | BOT-2 MABC-2 Beery-6 McMaster-3 ADL questionnaire |
diagnosis in Canada for FASD | FASD: A guideline for diagnosis across the lifespan Can happen at any age, but most common at 8-12 years |
common features of FASD | Impulsive Difficulty w/ cause & effect Difficulty w/ time & money Literal Do better with younger people Invisible disability Need "external" brain |
3 common facial features of FASD | Small eyes Flat philtrum Thin upper lip Only 10% have this |
prevalence of impaired motor skills | 51% fine motor 37% gross motor 30% total motor Functional motor skills (shoelaces, dressing, bike riding) |
sensory processing & FASD | High rates in people with FASD 73% had SSP scores in definite difference range Become overwhelmed in busy env, sensitive to textures, picky eating, attention difficulties |
FASD ADL difficulties | Hygiene Disorganization- losing things Sleep- falling asleep No concept of time Money management Friends- immature interests & social skills Independence- rely on caregiver |
FASD interventions | Routine/ structure/ repetition Visual cues Being external brain Adaptive aids for motor difficulties Regulation strategies |
strengths of FASD | Friendly Likeable Affectionate Determined Hard working Forgiving Non-judgmental Caring |
visual perception vs. multisensory learning | Total process responsible for reception & cognition of visual stimuli vs. Get info in through more than 1 sense. Effective learning strategy for all learning types |
perceptual development | First get tactile, kinesthetic, vestibular perception Visual & auditory become more dominant w/ age Identify forms/ shapes years before copying them Boys prefer kinesthetic longer |
perceptual development 1. learning at school for 6-7yo 2. grade 3 3. grade 5 | 1. Kinesthetic-> tactile -> visual -> auditory 2. Preference for visual input 3. Learn through auditory input |
types of learning styles | Visual Auditory Verbal Physical/ kinesthetic Logical Social Solitary |
visual receptive | Acuity, fixation, scanning, tracking How we receive the information from the world |
visual receptive development 1. Newborns 2. 2 weeks 3. 6-8 weeks | 1. Focus best ~1ft from face 2. Recognize mother's face 3. Fix gaze & follow moving object |
visual receptive development 1. 3 months 2. 4 months 3. 6 months | 1. Shifts glance between 2 objects 2. Sees detail & color 3. Eyes move independent from head, some depth perception developing, accurate tracking, easily shifting gaze |
visual receptive function in children | 5yo can control tracking in all directions, reach max accommodation 90deg field until age 9, implications of street safety Problems for those w/ epilepsy, down syndrome, intellectual disability, CP, TBI, illness |
warning signs of visual receptive function | Poor reading comp Hard to copy info from 1 place to next Loss of place, omission, repetition while reading Hard to change from far to near Poor posture & handwriting Word reversal Diff judging size & shape |
strabismus | Muscle imbalance, eyes don't line up & cross eyed ~4% of children, increased with DS & CP Brain learns to ignore 1 eye (CIMT like tx) Corrected when you catch it early |
nystagmus | Fast involuntary movements of eye, makes fixating difficult Reduced distance vision In developmental disabilities, 50-66% have ocular motor disorders |
cortical vision impairments | Mild to lack of light perception Damage to visual cortex, pathways Improves over time, tx helps |
intervention for cortical vision impairments | Positioning Breaks Uncluttered environment Contrast (dark & light) Bright colors Familiarity of objects/ toys Pair w/ other sensory system Place in periphery |
visual cognitive | Making sense of the light coming in Includes attention, memory, discrimination |
components of visual discrimination | Recognition Matching Categorization |
object vs. spatial perception | Form constancy Visual closure Figure ground discrimination vs. Position in space |
form constancy vs. visual closure | Present in newborn, big improvement around 6-7 yo Objects same in diff environments, positions, sizes More refined over time vs. Can tell what something is, even when partially blocked |
figure ground vs. position in space | Differentiate foreground & background. Improves btwn 3-5yo, stable at age 7 vs. Relative oneself to others, needed for understanding directional language. Continues to develop until age 4 |
visual discrimination impairments | Impairments in object perception w/o impaired spatial perception Unusual to have impairments in just 1 aspect of object perception |
how young kids look at pictures | Fixate on portion Ignore outer portion Unable to focus on relevant details/ focus too long |
visuomotor integration | Integrating visual image w/ appropriate motor response Not well understood Performance component |
visuomotor integration & child occupations | Related to handwriting readiness, kindergarten kids use visual feedback Kids rely less and less on visual feedback due to need for speed Use when concerned about integration of visual & motor skills Motor planning is good predictor of legibility |
who might you see with visual problems | Has average/ above average cognitive skills Diagnosed with learning disability Handwriting has letter reversals, problems w/ spacing, problems w/ legibility |
specific learning disorder | Diff learning & using academic skills Skills measured on standardized test and below expectations, interferes w/ occupational performance Begins during school age years Not explained by other conditions |
universal design for learning | Options that support kids w/ learning disabilities but all kids can benefit from strategies Ex. visual schedules, keyboard options, flexible seating, audio recordings, written copies, classroom design |
ax visual function | Is there a problem? What is the problem? How severe is the problem? |
observation for visual function | Task analysis is key How is it affecting functional performance & engagement |
developmental intervention vs. compensatory for visual function | Warren's model (bottom up), foundational skills such as attention, scanning, pattern recognition vs. Top down, reduce clutter & distractions (less material, contracts, masking, whiteboard/slant, lighting) |
cognition components | Thinking Memory Attention Intelligence |
why is cognition important | Performance component that's interconnected w/ other areas |
cognitive intervention strategies | Compensatory strategies Use of cognitive strengths to address other impairments (strength based approach) Match task to child (development level) |
cognition | Thinking, remembering, reasoning & making sense of world around us Includes ability to perceive, organize, assimilate & manipulate info Enables person to process info, learn, generalize |
vygotsky | Development occurs through interaction with environment Cognitive processing requires influence of another person (social before internal, internalization of social interactions) |
vygotsky 3 main stages of development | 1. Thought & speech not related 2. ~2yo, thought & speech connected. Speech follows action, self talk 3. ~7yo, thought & language connected, complex thoughts are possible. Inner speech particularly important in planning cognitive operations to plan |
zone of proximal development | Learner can do with guidance Very dynamic Support from adult has been internalized More knowledgeable other, educational tech, scaffolds/ prompt/ modelling |
scaffolding | Bridge between what they can do & cannot do yet Match amount of assistance to needs. Helps perform task within their zone of proximal development |
scaffolding strategies | Procedural Coaching Cuing Guided questioning Modeling/ gestures |
1. procedural 2. coaching 3. cuing | 1. Adult pauses, child fills word in 2. Help recognize when to use skill, provide feedback, encourage 3. Physical, visual, verbal prompt |
guided questioning vs. modeling | Open-ended questions to help talk through steps vs. Example to copy |
executive functioning | Complex neuropsych concept referring to coordinated ability to plan, initiate, organize, connect info, transition, shift mindset, set goals, prioritize, remember, self monitor |
executive skills patterns | Can be strengths and weaknesses Normal developmental variations In times of stress, executive skills decrease and impacts performance Weakest skill is first to go |
1. working memory 2. inhibitory control/ response inhibition 3. cognitive/ mental flexibility | 1. Recall past event, put it in present situation, manipulate info in mind 2. Keeps us from doing whatever comes to mind 3. Switch gears, adjust to changes |
development of executive functioning skills | Born w/ potential to develop skills, but environments will impact the development Chaotic & stressful environments will often lead to poor regulation. Emotional brain is bigger and more dominant. Strengthened through practice & experience |
executive functioning development 1. age 3 2. age 5 3. age 7 | 1. Able to follow 2 step direction, needs to be related though 2. Understand application of simple rules 3. Refinement & efficient use of executive functioning skills |
executive functioning skills linked to | School achievement Social development Moral development Emotional development |
executive functioning & OT | We use terms like self-regulation, awareness, monitoring, socio-emotional learning Use programs like zones of regulation and alert program On you to eval & educate |
zones of regulation | Zone scans Giving kids vocab & name the state they are in can help understand what they are feeling Can pick appropriate solutions |
assessing executive functioning | Add EF into clinical reasoning to align with top down approach Gain insight into occupation & what is needed for environment Child develops advocacy, adapt stuff |
EF in school environment | Support learning processes Give skills to master content Recall steps in daily routines Participate in discussions Play w/ peers Skills positively correlates w/ academic outcomes |
teachers say | Transition to school requires self control and sustained attention Unregulated children can't learn |
children with reduced EF struggle with | Maintaining friendships Studying skills Holding down a job Managing different crisis |
developmental coordination disorder | Performance with coordination is below expected level for age and that they were given opportunities to learn Often called clumsy Interferes w/ ADL Early onset Higher in boys, unknown cause Less diagnosed |
developmental coordination disorder poor postural control vs. difficulty in motor learning | Muscle tone, static & dynamic balance, distal control vs. Learning new skills, adapting to change, planning movement, automatization |
developmental coordination disorder poor sensorimotor coordination | Coordination Use of feedback Determining force & speed Sequencing of movement Timing Strategic planning |
related conditions to developmental coordination disorder | ADHD- 10% Speech & language- 30-70% Autism Executive functioning Anxiety & depression Sleep disturbances Visual deficits |
intervention for developmental coordination disorder grounded in | Person & family centered care Motor learning Dynamic systems Top down is better |
developmental coordination disorder intervention 1. early childhood 2. middle childhood 3. later childhood | 1. Motor skills, play 2. Self-care, academic, issues w/ peers 3. Self concept, emotional health |
education & advocacy for developmental coordination disorder | Child & parents Partners: teachers, EAs, counselors, family workers Community supports |
measures of cognition | Screen for cognitive challenges- ASQ, DAYC-2 Assess selected aspects- school function, BRIEF Use results of others testing- perceptual reasoning, processing speed |
intellectual developmental disorder | Impairments of general mental abilities that impact adaptive functioning in 3 areas Domains determine how well an individual copes with everyday tasks Conceptual, social, practical domain |
intellectual developmental disorder 1. conceptual domain 2. social domain 3. practical domain | 1. Language, reading, writing, math, reasoning, knowledge, memory 2. Empathy, social judgement, interpersonal communication, making friendships, similar capacities 3. Personal care, job responsibilities, money management, rec, school & work |
intellectual developmental disorder 1. mild 2. moderate 3. severe 4. profound | 1. IQ of 55-70, more concrete, emotional challenges 2. IQ of 40-55 3. IQ of 25-40, needs lots of support 4. IQ under 25, may be non verbal |
intellectual developmental disorder intervention | Define task Anticipate difficulties Set up environment to explore & select strategies Encourage applying strategy Assist child to evaluate & modify |
intellectual developmental disorder setting up framework | Establish routines at home & school Modeling & cueing Task analysis Fwd & bwd chaining Capitalize on strengths while addressing weaknesses |
CO-OP | Tx approach for those w/ difficulty doing tasks Performance based Helps people talk to themselves through a task Need active engagement of client |
7 key CO-OP features | Client chosen goals Dynamic performance analysis Cognitive strategy use Guided discovery Enabling principles Parent involvement Intervention format |
dynamic performance analysis | Client want to do occupation? Know what to do? Performance breakdowns? Specify intervention strategy What are occupational demands? Environmental demands? |
goal-plan-do-check | What do I want to do?- Self interrogation How am I gonna do it?- Self-monitoring Carry out plan- self-observation How well did my plan work?- Self eval, reinforcement |
BATSFVV | Body positioning Attention to doing Task modification Supplementing task knowledge Feel the movement Verbal motor mnemonic Verbal rote script |
supplementing task knowledge vs. feel movement | Tell child things they may not know & how to get task specific info vs. Attend to feeling of a movement |
verbal motor mnemonic vs. verbal rote script | Name a task or part of a task, create mental image vs. Pattern of words to guide movements that are meaningful of child. Give verbal guidance & modeling, then have verbal self guidance |
guided discovery | One thing at a time Ask, don't tell- client gets info without being told to them, reflexive questions Coach, don't adjust- collaborative problem solving after failure Make it obvious- obvious cues |
enabling principles | Make it fun Prompting, fading, chaining, modeling, reinforcement, direct teaching, shaping Work towards independence Promote transfer & generalization |
