4 points…
POINT #1 traditional models for understanding children’s behavior are inadequate to the current task
Traditionally, focused on measurement— of a child’s abilities
Measuring children’s abilities Psychometric paradigm Skill based Factor analysis of cognitive constructs underlying skills Emphasis on inter-child ranking…
In 2011…. Neuro Neuropsychology: biology Emphasis on biology
Biological organism behaving in environment
Emphasis on whole child as unit of analysis intra-child Analysis is intra-child
Clinical goal …increase success of organism’s behaving in environment [ecological validity defined in terms of organism acting in niche]
Assessment Evaluation data collection clinical analysis diagnosis Management education intervention [Rx & Tx]
POINT #2 Neuro = brain
What “drives” brains….?
INSERT CLASSROOM IMAGE
NOPE!! NOPE !!
What “drives” brains….?
Perpetuation of the species
What “drives” brains….? Food Fight Flight Friends
What “drives” brains….? Food Fight Flight Friends Preservation of self
What “drives” brains….? survival …. …. survival …. of the individual…. of the species….
“What drives brains?” Evolutionary context of ‘brain ’
What are brains for?
Thinking….
What are brains for? Doing! Motor action…….
POINT #3
How do brains work……
Digression… You are part of an intellectual tradition….
A bit of history…… For >500 years: For >500 years: The person has been at the center of how we think about ourselves The person has been at the center of how we think about ourselves
Fundamental assumption…. “..autonomous individual is center of knowledge and cognition..” (Dumont, 1965) “..the boundaries of the individual provide the proper framework within which psychological processes can be adequately analyzed..” (Wertsch et al., 1985)
Cognition: = set of processes that are internal and accessible only to the person to whom they belong
Fits with our experience of the world Fits with our experience of the world Important for our psychological health Important for our psychological health
Fine….. BUT….. BUT….. It’s wrong!!!!! And we have NEUROSCIENCE to thank…..
Why is this important? This long-held belief shapes learninglearners. how we understand learning and learners. psychologicaleducational research It shapes psychological and educational research…. education system It thus shapes our education system. …and,
More recent times…. Emphasis has shifted from child-as-learner Tochild-as-owner-of-the-learning-organ
Brain….
Brain… get built Doesn’t develop in a vacuum function
[BRAIN CONTEXT]
Can you have dyslexia if no-one ever asks you to read?
No ! Biological vulnerability versus Manifest symptom
Brain-Context interaction Physical Brain systems Neurochemical bath Physical world [space, light, sound..] Psychological Social Emotional Beliefs, goals, values
Context Tendency to think SPATIAL context But, not just spatial (here-and-now);
Context Not just spatial (here-and-now); but TEMPORAL is critical to the analysis but TEMPORAL context is critical to the analysis how-did-it-get-this-way? (history: how-did-it-get-this-way?)
Context Temporal Temporal context: evolution of THE brain evolution of THE brain construction of the current social setting construction of the current social setting developmental experience of THIS brain developmental experience of THIS brain

PARADIGM [monkey] Recording of MT neurons Analysis noise correlations simultaneous recording identical visual stimulus Behavioral context cooperative interactions & competitive interactions.
MT neurons receive inputs of central origin whose strength changes with the task structure Cohen & Newsome, Neuron 2008
Context… MEANING to the organism.. at the time..
How do brains work…… Importance of the brain context [ brain context ] interaction Brain as both independent and dependent variable
POINT #4
Cardinal feature of child ? Developing…………
Theoretical Matrix….. BRAIN BRAIN: substrate for behavior CONTEXT CONTEXT: brains do not operate in isolation DEVELOPMENT DEVELOPMENT: dynamic change
Developmental models…. Change – and continuity………… (Obligatory) transactions with context Non-linear; successive re-organization
Why?
Implications for assessment ? For design/methodology For selection/collection of data For interpretation of observations For management/intervention planning
And also…… For research questions ? For theories of neurobehavioral development ? For research design/methodology ?
Remind you….. Research investigations : seek universals are variable- centered maximize internal validity
Remind you….. Research investigations Research investigations.. seek universals are variable- centered maximize internal validity Clinical investigations.. deal with individuals are person-centered maximize external validity
Remind you….. Research investigations Research investigations.. seek universals are variable- centered maximize internal validity Clinical investigations.. deal with individuals are person-centered maximize external validity How do you resolve this tension? How do you apply research-obtained knowledge to the individual case?
