Identifying Atypical Development

What is developmental regression?

Loses in milestones

What is atypical development?

Extremes of individual differences in development

Which domains does development occur over?

Adaptive behaviour, social, cognitive, physical, motor skills

What is the adaptive behaviour domain?

Skills used to navigate daily life

What is the social domain?

Social skills

What is the cognitive domain?

Mental Skills

What is part of the experimental process when measuring atypical development?

Control group

Why cant we build a full profile of a child's abilities?

Need to identify strengths & weaknesses

How can we measure multiple domains of development?

Specific experimental designs

What is a standardised test?

Fixed format with specific instructions, questions & scoring procedures

What happens to participants scores so that they can be compared to other individuals?

They are assigned a value to indicate performance (Standardised)

What is an example of a standardised test?

Weschler Intelligence Scales for children (WISC)

What is the difference between standardised & specific tests?

Standardised measure broader factors

What does the WISC measure?

Different forms of intelligence

How can adaptive behaviour be measured in development?

Semi-structured interview

How can we test non-verbal participants?

Visual stimuli

How can we test younger participants?

Observations

How can we interpret the scores of task performance?

Use standardised scores

How can we create standardised scores?

Compare raw score to the mean

What are the benefits of standardised scores?

Standandises performance
