Q

Possible benefits of identifying earliest signs of ASD

A
  • Careful study of processes that may be affected by atypical developmental trajectory
  • Insights into biological mechanisms of typical social development
  • Earlier identification, screening, and intervention
  • Possible prevention of full syndrome

16
Q

Retrospective studies

A

Conducted after the events of interest have occurred (parent report, home videos)

17
Q

Prospective studies

A

Conducted by starting with two groups at the current point, and following up in the future for occurrence

18
Q

Symptoms seen in infant sibs of children with ASD

A
  • Less likely to respond to their name
  • Initiated fewer behavioral requests
  • Displayed fewer gazes to faces
  • Less likely to initiate or respond to acts of joint attention
  • Fixation on objects
  • More severe reactions to distress
  • More time spent looking at non-social objects
19
Q

Other notable symptoms

A
  • Smaller vocabulary
  • Limited concern for others’ distress
  • Rotate and spin objects
  • Difficulty with transitions
  • Poor motor imitation skills
20
Q

Limitations of HR infant sib studies

A
  • Variability in data
  • Stressors (such as growing up with a sibling with autism) may affect development
  • HR sibs with a greater genetic probability of developing ASD may be different than those who do not have this genetic loading
21
Q

Which appears first, social deficits or communication deficits

A

Social deficits

22
Q

Asperger syndrome

A

ASD symptoms occur without a clinically significant delay in language or in the development of cognitive ability or adaptive behaviors/self-help skills

23
Q

Diagnostic substitution

A

one label for a condition (autistic disorder) becomes replaced with another (ASDs), causing an apparent decrease in the rate of the first condition and increase in the rate of the second

24
Q

Reasons for detected “increase” in prevalence of ASD

A
  • Increased awareness
  • Diagnostic substitution
  • Changes in diagnostic criteria
  • Access to services
  • Improved quality & quantity of records
25
Q

Who first discovered autism

A

Leo Kanner, 1940s

26
Q

Adaptive behaviors

A

the collection of conceptual, social, and practical skills that people learn in order to function in their daily lives

27
Q

ASD diagnoses are made based on

A

Behavioral observations and developmental/family history
