Transcript of Dissertation Presentation

Introduction Results Discussion Discussion Extreme Male Brain Extreme Female Brain ASD Psychosis Deliberative Intuitive Method Do intuitive and deliberative thinking styles map onto the extreme male, extreme female brain continuum? Melissa Hollinworth ASD Psychosis Baron-Cohen (2003) Empathising -Systemising theory
- ASD - Male - Female - ?

Crespi and Badcock (2008) ASD
Psychosis continuum

Kahneman (2011) & Evans (2007) - two systems
Hammond (1996,2000) - Cognitive Continuum Theory Study 1: ASD and Junior school
Design: between participants
Participants:
- ASD unit: 21 males, 5 females 11-14 years (clinical sample)
- Junior school: 22 males, 24 females 10-11 years (control)
Procedure:
- Cognitive Reflection Test (CRT)
- Rational-Experimental Inventory (REI) Study 1
Strengths
- Attempts to control for ability
- Attempts to investigate thinking styles
Limitations
- Measure may not capture thinking styles
Implications
- ASD and Extreme Male Brain?
- Further research is necessary to establish if differences in thinking styles exist Introduction Study 1:
Aim: Identify difference in thinking styles between ASD and Junior school
Hypothesis: ASD = deliberative
Junior school = intuitive
Study 2:
Aim: Map thinking styles onto Autism-Psychosis continuum
Hypothesis:
- High autistic traits = deliberative thinking
- High psychotic traits = intuitive thinking Method Study 2: Students
Design: within participants
Participants: Students: 40 males, 40 females 18-21 years (non-clinical)
Procedure:
- Cognitive Reflection Test (CRT)
- Rational-Experimental Inventory (REI) Study 1: ASD and Junior school

Cognitive Reflection Test (CRT)
- Difference between groups
- Not related to thinking styles?

Rational-Experimental Inventory (REI)
- No difference in self reported thinking styles

Study 2: Students
- data not fully analysed Extreme Male Brain Extreme Female Brain Any Questions? Negative symptoms of Schizophrenia and ASD in children
Low comorbidity between disorders
Some misinterpretation of symptoms in childhood?
Distinguished using genome impriting Crespi & Badcock
(2009) Interventions Deliberative thinking and interventions in ASD
Intuitive thinking and interventions in psychosis
Aid improving or reducing level of social cogntion - if possible
Future research to test interventions Study 2:
Strengths
- Continuum allows for individual differences
- Accounts for psychosis end of spectrum
Limitations
- Student sample (not generalisable)
- Non clinical sample
Implications
- Aid understanding and conceptualisation of disorders
- Enhance interventions in the future - Self-report measures of psychotic traits and autistic traits
