Cognitive Approach
BaronCohen --
Cognitive
approach
Background BC's own research with children (SallyAnne test) other tests with
adults (Happe)
sample Autistic/Asperger Syndrome (ASD) 13 m 3 f Tourettes Normal 25f+25M
(nonuniversity, matched for age range)
Sample method ASD: Self selecting (advert in autistic magazine) + some known to BC
Tourettes: self selecting invited via clinic
Normal: "random" from Cambridge University pool of volunteers
Method Lab experiment Quasi
IV Autism / Normal / Tourette's (control)
DV score when `reading' eyes
Technique Selfreport
results ASD Ps lower mean scores in eyes test + strange stories task cf.
Tourette's & normal Ps. All Ps = comparable scores on 2x control tasks
Conclusion Eyes task is useful alternative test for ASD (concurrent validity cf.
qualitative Happe's strange stories + quantitative) Reading emotion in
eyes requires Theory of Mind

approach
Background Claim that only humans can learn language (LAD theory) previous
research with chimps and language
Sample Two pygmy chimpanzees (Bonobos), Kanzi ands his sister Mulika.
Two common chimpanzees Sherman and Austin.
Sample method Opportunity (Kanzi's learning found "serendipitously" before study)
Method Lab/quasi experiment
Method Case study
Techniques Observation (including `blind' trial) and testing (verbal and nonverbal)
Results Kanzi learnt like a human child because he copied things from his mum at
first and then started learning for himself like a child Bonobos responded
well to speech, common chimps angry and confused common chimps
overgeneralised Bonobos requested items for each other, common
chimps only for themselves

Weaknesses often relies on Selfreport technique = demand characteristics
Usually studied through laboratory experiments [SR = case studies
in lab conditions] so lack ecological validity
often reductionist ignores the complexity of human functioning e.g.
biological / social / psychodynamic factors

Approach

Strengths Explanations:
why differing ages demonstrate different intellectual abilities, social skills
and emotional responses
Adding knowledge to the continuing nature versus nurture debate
Applications: Controlling violence on children's TV (Bandura) Helping
teachers understand learning processes (Samuel and Bryant)
Methodology: use of variety of approaches = match method to issue
under investigation (considering all 3 studies)
Weaknesses Determinism: Many proposals about agerelated development have been
