Cognitive & Motor DomainsEvolution of domains
Categorizing human behavior into domains evolved because it is useful in organizing and simplifying the study of human development
Cognitive and motor development interact continually throughout the lifespan as they reciprocally inhibit or facilitate each other

Cognitive & Motor DomainsHow does our gradually changing motor ability affect our cognitive development?
How does our evolving cognitive development affect our motor development?
What are some significant areas of integration?

Psychomotor or Motor?Psychomotor: interaction between mind (psycho) and movement (motor)
Stimulus comes from higher brain centers
Motor Any human movmentInitiated from lower brainIncludes reflexive movement

Jean Piaget and Cognitive Development
1896-1980
Cornell University, 1964
Swiss psychologistinterested in the process
of thinking
Established the clinical
method of research
Collected data in question-and-answer
sessions

Cognitive DevelopmentPiaget’s Theory
Four major stages of cognitive developmentSensorimotor Prepoperational Concrete operational Formal operational
All children follow the sequence in orderRate and degree of completion may differ

Piaget’s Cognitive DevelopmentStage Age/Period of
Occurrence
Sensorimotor Birth to 2 years
Preoperational 2 to 7 years
Concrete operational 7 to 11 years

Piaget’s Cognitive TheoryAdaptation
Cognitive development occurs through adaptationA way of adjusting to the demands of the envirnomentTwo facets of adaptation
AssimilationAccommodation

2-10
Adaptation
Assimilation Accommodation
Process by which children attempt to interpret new experiences based upon their present interpretaiton of the world
Adjustments or modifications in the thinking process which will become a part of a child’s new cognitive repetoire
![Page 11: Cognitive and Motor Development Chapter 2 McGraw-Hill/Irwin © 2012 McGraw-Hill Companies. All Rights Reserved.](https://reader038.fdocuments.in/reader038/viewer/2022103100/56649f325503460f94c4db40/html5/thumbnails/11.jpg)
2-11
Components of the Process of Adaptation
Component Process
Assimilation Children try to interpret new experiences based on their present interpretation of the world
Accommodation Children try to adjust existing through structures to account for (accommodate) new experiences
![Page 12: Cognitive and Motor Development Chapter 2 McGraw-Hill/Irwin © 2012 McGraw-Hill Companies. All Rights Reserved.](https://reader038.fdocuments.in/reader038/viewer/2022103100/56649f325503460f94c4db40/html5/thumbnails/12.jpg)
2-12
Components of the Process of Adaptation
Assimilation Child tries to grabs a large ball with one handHis experiences of the past tell him that he can use one hand to grab hold of an object because it worked with rattles and smaller objectsThe child assimilates his past experiences
![Page 13: Cognitive and Motor Development Chapter 2 McGraw-Hill/Irwin © 2012 McGraw-Hill Companies. All Rights Reserved.](https://reader038.fdocuments.in/reader038/viewer/2022103100/56649f325503460f94c4db40/html5/thumbnails/13.jpg)
2-13
Components of the Process of Adaptation
AccommodationUsing the same example, when the child is unable to grasp the football, he may try to adjust or accommodate by using two hands or even adapting the one-handed grasp

2-14
Criticisms of Piaget’s Theory
Theory lacks scientific controlPiaget used his own children to studySubject’s were not studied across the lifespanPiaget may have underestimated a child’s capabilities
Theory does not discern between competency and performanceTheory does not account for the influence of motivation and emotionStages of developoment were too broadDevelopoment is described, but never explained
![Page 15: Cognitive and Motor Development Chapter 2 McGraw-Hill/Irwin © 2012 McGraw-Hill Companies. All Rights Reserved.](https://reader038.fdocuments.in/reader038/viewer/2022103100/56649f325503460f94c4db40/html5/thumbnails/15.jpg)
2-15
Criticisms of Piaget’s TheoryMost criticized aspect of the theory is that formal operational thought can be achieved as early as 11 years of age
No account for adult development in his theoryCognitive development continues throughout adulthood
Child may have been completely competent, but due to motivational or emotional circumstances could not perform the task well

2-17
Infancy ~ Sensorimotor StageSubstage Age of Occurrence
Exercise of reflexes Birth to 1 month
Primary circular reactions 1 to 4 months
Secondary circular reactions 4 to 8 months
Secondary schemata 8 to 12 months
Tertiary circular reactions 12 to 18 months
Invention of new means through mental combinations

2-18
Infancy ~ Sensorimotor Substage 1-Reflexes
Exercise of reflexesBirth through 1 monthRepetition of reflexes helps child to form the foundation for cognitive understanding
Reflexive movements do not need higher brain centers to be initiatedReflexive movements lead to new behaviors

2-19
Infancy ~ Sensorimotor Substage 2-Primary Circular Reactions
Primary circular reactionsOnset of increased voluntary movement1-4 months
Consciously create movementCalled circular and primary because movements always occur in close proximity to the infant

Infancy ~ Sensorimotor Substage 3-Secondary Circular Reactions
Secondary circular reactions
4-8 monthsContinuation of primary circular reactions

2-21
Infancy ~ Sensorimotor Substage 3-Secondary Circular Reactions
The infant’s interaction with the environment expandsChild begins to integrate vision, hearing, grasping and movement behaviorsCan imitate behaviorsNo permanence – remove object – object is gone
![Page 22: Cognitive and Motor Development Chapter 2 McGraw-Hill/Irwin © 2012 McGraw-Hill Companies. All Rights Reserved.](https://reader038.fdocuments.in/reader038/viewer/2022103100/56649f325503460f94c4db40/html5/thumbnails/22.jpg)
2-22
Infancy ~ Sensorimotor Substage 4-Secondary SchemataSecondary schemata
8 months to 1 yearPast movement actions applied to new situations New behaviors emerge

2-23
Infancy ~ Sensorimotor Substage 4-Secondary SchemataNew behaviors are facilitated by increasing movement capabilities such as crawling and creeping which allow exploration of the environment
Repetition of experimentation and trial-and-error exploration continue
![Page 24: Cognitive and Motor Development Chapter 2 McGraw-Hill/Irwin © 2012 McGraw-Hill Companies. All Rights Reserved.](https://reader038.fdocuments.in/reader038/viewer/2022103100/56649f325503460f94c4db40/html5/thumbnails/24.jpg)
2-24
Infancy ~ Sensorimotor Substage 4-Secondary SchemataChild can predict some actions and situations
Roll ball to child – he crudely roles it back – he anticipates you rolling the ball to him again
The ability to predict (Piaget) is the onset of intellectual reasoning

WAIS – Wechsler Adult Intelligence Scale
Found declines in intellectBut, this test is not designed to measure intellect – it is designed to ascertain psychopathological behaviors clinically
