Development of a child may be influenced by intrinsic or extrinsic factors. What are some extrinsic factors that may affect development?
True or false? Attainment of a particular developmental milestone or skill depends on the achievement of earlier skills.
almost always true, rarely are skills skipped
Give two ways in which a delay or deficit in one developmental domain may affect another domain.
- a deficit in one developmental domain may compromise the assessment of skills in another domain
How might motor deficits affect a child’s cognitive development?
neuromuscular disorders affecting the child’s ability to explore the environment may compromise cognitive development
True or false? A normal developmental screening test should outweigh parental concern.
often false; because many developmental screening tests lack sensitivity, parental concern should not be disregarded
What is a developmental quotient and how is it calculated?
DQ = (developmental age/chronological age) x 100
Gross motor development evaluation includes assessment of what two sets of actions?
- neuromaturational markers (i.e. primitive reflexes and postural reactions)
What are neuromaturational markers?
a term used to describe primitive reflexes and postural reactions
What is the difference between a primitive reflex and a postural reaction?
How will CNS injury affect primitive reflexes and postural reactions?
Describe the moro reflex, when it appears, and when it should disappear.
Describe the hand grasp reflex, when it appears, and when it should disappear.
Describe the atonic neck reflex, when it appears, and when it should disappear.
Describe the rooting reflex, when it appears, and when it should disappear.
Describe the head righting postural reaction, when it appears, and when it should disappear.
Describe the parachute postural reaction, when it appears, and when it should disappear.
What general change occurs in the second year of life with regards to fine motor skills?
infants learn to use objects as tools
Give four red flags with regards to delayed motor development.
What is usually the earliest sign of neuromotor problems through the course of infant development?
persistent fisting beyond 3 months of age
Early rolling over, early pulling to a stand instead of sitting, and persistent toe walking could all be indicators of what?
spasticity
When should hand dominance first arise in children? What is early hand dominance often a sign of?
- early dominance may be a sign of weakness of the opposite upper extremity associated with hemiparesis
Delays in which developmental domain are most common?
delays in language
How does the development of receptive language compare to expressive language?
receptive language is always more advanced; children usually understand 10 times more words than they speak
What is the difference between speech and language?
- speech is the vocal expression of language
