36
List the 4 developmental theories
1) Neuromaturational
2) Psychosocial/Psychoanalytical
3) Ecological, Contextual
4) Dynamic Systems
37
What are the basic concepts of Neuromaturational theory?
1) Development follows a set, invariant sequence.
2) Development is tightly tied to central nervous system development.
3) Motor development is cephalocaudal and proximal to distal.
4) Recent modifications acknowledge variations in the sequence and input from all systems.
38
What are the basic concepts of Ecological, Contextual theory?
The environment has a very strong influence on child development
39
What are the basic concepts of Psychosocial/Psychoanalytical theory?
1) There are biologically determined drives and unconscious conflicts.
2) The core of these conflicts is sexual.
3) Initial drives are for survival; when basic needs are met, we seek self-actualization.
40
What are the basic concepts of Dynamic Systems theory?
1) Movement emerges based on the internal enviroment, the external environment, and task.
2) Movement is not directed by one system, but by many dynamic, interacting systems.
41
What are the types of play and associated actions in infants (6-12 mo)
Types of play:
1) exploratory (sensorimotor becomes functional play)
2) functional (begins to use toys based on their functional purpose)
3) social (attachment to parents/caregivers)
42
What are the types of play and associated actions in infants (0-6 mo)
Type of play:
1) exploratory (sensorimotor play predominates)
2) social (focused on attachment and bonding)
43
What are the types of play and associated actions in infants (12-18 mo)
Types of play:
1) relational and functional (simple pretend play toward self, links 2-3 schemes in simple combinations, exhibits imitative play from an immediate model)
2) social (beginning of peer interactions during play, parallel play next to a peer)
3) gross motor (explores all aspects of a room, rolls and crawls in play)
44
What are the types of play and associated actions in toddlers (19-24 mo)
Types of play:
1) functional (performs multiple related actions together)
2) gross motor (might enjoy the sensory input, makes inanimate objects real “feed and dress,” pretends objects are real or symbolize another object)
3) social (parallel play, imitates others in play, watches other children, participates with several children, begins to take turns)
45
What are the types of play and associated actions in preschoolers (2-3 years)
Types of play:
1) symbolic (plays house, plays out drama with toys or imaginary friends, uses objects for multiple pretend ideas, multiple scheme combinations into meaningful sequence of pretend play)
2) constructive (imitates adults using toys, participates in drawing and puzzles)
3) gross motor (likes jumping, tumbling)
4) social (associative, parallel play dominates)
46
What are the types of play and associated actions in preschoolers (3-4 years)
1) complex imaginary (creates scripts for play where pretend objects have actions reflecting real or imaginary roles)
2) constructive (creates art product with supervision, completes puzzles and blocks)
3) rough and tumble (enjoys physical play, swinging, jumping, running)
4) social (singing and dancing in groups, participates in circle time and games at preschool, associative play with other children, sharing and talking)
47
What are the types of play and associated actions in preschoolers (4-5 years)
1) games with rules (group games with single rules, organized play with prescribed rules, organized gross motor games)
2) constructive (interested in the goal of the art activity, constructs complex structures, takes pride in products)

4) social play (participates in organized play in groups)
49
What are Piaget’s stages of play (0-2 years old)
Practice:
1) unoccupied play: play with objects, no purpose, banging rattles, mouthing
2) onlooker play: watches someone else play
3) solitary play: ignores others but plays with purpose
50
What are Piaget’s stages of play (3-5 years old)
Symbolic Play:
1) parallel play: independent play but shows awareness and interest in others (same activity next to each other but not together)
2) associative/interactive play: initiate contact with other children, play house, superheroes and other make believe games (sharing, taking turns and make believe are a big part of this stage)
51

Rule Play:
1) cooperative play: simple organized games, shared toys, all participating
2) competitive play: complex regulated team sports, self competition
52
What happens to vestibular sensitivity from 2.5 years old to puberty?
Increases
53
How does the integration of sensory information affect the child?
Improves practice as well as motor planning and execution
54
Describe flexibility and specificity in development action
Karen Adolph:
1) flexibility: adapting ongoing movement to novel changes in local conditions (allows child to problem solve in the moment, “learning set” to deal with a novel situation)
2) specificity: simple association learning (relatively fast “1 day,” not as good in coping with a novel situation)
55
What are some key points for learning specificity?
1) Accomplished via simple association (less flexible strategy)
2) Cannot adapt to novel change
3) Always fall on 1st trial (in the paper)
4) Speed of learning depends on age & # exposures
56
What are some key points for learning flexibility?
1) must “look, touch, test alternatives, explore, visually explore space”
2) Not age or #exposures to surface dependent
3) But is experience dependent, i.e. active exploration
57
What is Taxonomy of tasks?
The practice and science of classification
Gentile’s 2 dimensions:
1) environmental (open or closed)
2) functional role
58
Explain the environment aspect of taxonomy
1) stationary environment (closed): objects, terrain and other people are stationary or fixed. Timing does not have to be specified, the performer has a choice as to when to start and end the task
Ex: putting on a shirt or walking down an empty hallway
2) moving environment (open): objects, other people, or supporting surfaces are in motion. Performers must match their movements to do both spatial and temporal features of the environment and predict future events. The timing is determined by the environment, meaning the movement is externally paced
59
Explain task variability
(Absent/present)
1) Intertrial Variability absent: requires the least amount of attention, it is very predictable, and motor memory is in the reproductive mode allowing the performer to simply reproduce the motion (after the initial learning phase is completed)
2) Intertrial Variability present: requires increased attention to detect the changes in the environment. The performer must constantly scan and attend to the environment to anticipate and compensate for changes. Motor memory is in the generative mode, meaning movement patterns are constantly being generated and refined to keep up with the changes
60
List movement analysis body constraints
1) stability
2) transport
3) manipulation absent
4) manipulation present
61
Explain the stability component of the body constraints movement analysis
1) Desired outcome is to keep the performer's Center of Mass (COM) over the Base of Support (BOS)
2) information processing is low and any conditions outside the immediate area (within reach) are irrelevant
3) activities requiring stabilization of the body within a limited environment or posture, such as sitting on a chair or standing on a bosu ball
62
Explain the transport component of the body constraints movement analysis
1) desired outcome is to move the body from one place to another
2) boundaries are constantly expanding in accordance with rate of motion. Information processing is high. As speed increases, the person must scan ahead to get use-able information
Ex: walking or running
63
Explain the manipulation absent component of the body constraints movement analysis
1) Activity performed without a second task involving manipulation by the extremities. The task involves control of body orientation and not manipulation of an object
Ex: Standing with empty hands, walking with empty hands
64
Explain the manipulation present component of the body constraints movement analysis
1) Two tasks are being performed simultaneously, postural stability is maintained as the extremities are doing something
2) Demand dual attention, the need to do 2 things at once (more difficult)
Ex: drink while standing or walking, LE dressing while seated or standing
65
If an individual is in an empty gym, standing in a specific spot, practicing shooting a basketball. What is the movement analysis?
1) closed environment
2) no intertrial variability
3) manipulation in body stability
4) no body transport
66
If an individual is in a full gym with people, standing in multiple spots across the gym, practicing shooting a basketball. What is the movement analysis?
1) open environment
2) intertrial variability
3) manipulation in body transport
4) no body stability
67
Explain malformation
A structural defect of an organ or body part due to an intrinsically abnormal developmental process (cleft lip/palate; polydactyly)
1) Major malformations are those that have medical, surgical, or cosmetic significance; these occur in 2-3% of liveborn infants.
2) Minor malformations are those that are insignificant except that they are important clues to diagnosis; if there are 3 or more minor malformations, you should suspect a genetic condition/major malformation is present.
68
Explain disruption
an abnormal breakdown of tissue in the normal fetus resulting in a defect of an organ or body part
(may be due to infectious, vascular, or mechanical origins)
Ex. Amniotic banding
69
How common are malformations?
anywhere from 5 - 40% of otherwise healthy individuals have one or more minor malformations (i.e. does the earlobe dangles or is it attached at the base?; ability to 'roll the tongue’, “tongue tie”)
1) Half of these minor malformations are in the head and neck region; 71% are in the upper torso if the hands are included)
2) 19% of infants who have 3 or more minor malformations also have a major malformation.
70
Explain deformation
An alteration in form, shape, or position of an organ or body part by mechanical forces
(Intrinsic or extrinsic)
Ex. Plagiocephaly
71
Explain dysplasia
an abnormal organization of cells in tissues that has structural consequences
(Skeletal dysplasia, renal dysplasia, singular palmer crease in individuals with Down Syndrome)
72
Define syndrome
A recognizable pattern of anomalies which have a common cause, either genetic or environmental.
(Chromosomal Syndromes, Contiguous Gene Deletion Syndromes, Single Gene Syndromes)
73
Describe sequence
A pattern of anomalies that are the secondary effects of an initial defect.
Ex: Spina bifida-the neural tube fails to close, resulting in interrupted spinal cord/paralysis, then hydrocephalus, neurogenic bladder, and club feet.
74
Describe association
A non-random occurrence of multiple anomalies
75
Describe chromosomal syndromes and list some examples
When there is an addition or deletion of a whole or part of a chromosome
1) Trisomy 21 Down syndrome: (most common 1/700 live births, 20% of all people with ID, short stature, low muscle tone, flat nasal bridge)
2) Monosomy X “Turner syndrome”: (females, sex abnormality, weblike neck, small stature)
3) Klinefelter syndrome: (males, not inherited extra X chromosome, infertility, long limbs, hypogonadism)
76
Describe contiguous gene deletion syndromes and give some examples
When there is a deletion of a set of genes that are close together on one chromosome
1) Prader-Willi syndrome: (mild intellectual impairment, short stature)
2) Angelman syndrome: (severe cognitive impairment, seizures, frequent laughter)
3) Williams syndrome: (autosomal dominant, heart defects, mild-moderate intellectual impairment)
77
Describe single gene syndromes and give some examples
When there is an abnormality of one gene
1) Sickle cell anemia (misshapen RBC affecting hemoglobin)
2) Marfan syndrome (inherited disorder affecting connective tissue, longer limbs)
3) Cystic fibrosis (autosomal recessive, hyperplasia of mucus producing cells in lungs, disorder of exocrine glands)
4) Duchenne muscular dystrophy (males, x-linked deletion of dystrophin gene, intrinsic muscle disease and weakness)
78
What are two common associations that have predictable defects/problems affecting multiple systems/structures?
1) CHARGE (autosomal dominant)
2) VACTERL
79

procedure used to obtain fetal cells for prenatal diagnosis; involves biopsy of the placental membranes
81
Define Consanguinity
relationship of 2 individuals through a common ancestor; mating in which the mates are related, i.e. first cousins
82
Define Fragile site
gap or defect in the continuity of a chromosome when strained, i.e. fragile X site; many are apparent only when cells are cultured under special conditions
83
Define gamete
