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….

Neuropsychology:

Emphasis on biology

Biological organism behaving in

environment

Emphasis on whole child as unit of analysis

Analysis is intra-child

Clinical goal

…increase success of organism’s behaving in environment

[ecological validity defined in terms of organism acting in niche]

“What drives brains?”

Evolutionary context of ‘brain’

What are brains for?

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:

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

Important for our psychological health

Fine….. BUT…..

It’s wrong!!!!!And we have NEUROSCIENCE to

thank…..

Why is this important?

This long-held belief shapes how we understand learning and

learners.

It shapes psychological and educational research….

It thus shapes our education system.

…and,

More recent times…. Emphasis has shifted from child-as-

learner To

child-as-owner-of-the-learning-organ

Brain….

How do brains work……

Importance of the [brain context] interaction

Brain as both independent and dependent variable

POINT #4

Cardinal feature of child ?

Developing…………

Theoretical Matrix….. BRAIN: substrate for behavior

CONTEXT: brains do not operate in isolation

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

centered maximize

How do you apply research-obtained knowledge to the individual

case?
