Forensic Psychology

View mindmap
    • profiling
      • bottom up approach (the sciency one)
        • + evidence supporting investigative psychology, evidence supporting geographical profiling
          • - database is only made up of solved crimes, mixed results, geographical profiling is not efficient on its own
        • statistical analysis of crime scene evidence detect patterns of behaviour likely to coexist over time
          • interpersonal coherence - the way in which an offender behaves at the crime scene
          • geographical profiling - aims to generate accurate location of offender's base and home
        • data driven approach - aims to generate picture of offenders' characteristics through analysis of evidence
      • top down approach (American one)
        • aims to narrow the list of likely suspects of an offender
        • organised type, e.g. above average IQ
          • disorganised type, e.g. impulsive nature displayed in crime scene
        • + evidence for organised category, adaptable
          • - flawed, organised typology = continuum
    • explanations
      • atavism (the racist one)
        • offenders lack evolutionary development
        • facial features & other physical/emotional features, e.g. high cheekbones
        • + lombroso = father of criminology
          • - racist, lack of evidence, poor methodology
      • genetic and neural
        • twin and adoption studies
        • candidate genes - genes --> criminality
        • diathesis stress model - genes are there, external factors trigger it
        • APD - neural differences in offenders' brains
        • less activity in pre-frontal cortex
        • mirror neurons may not be turned on
        • - twin studies = not equal environments, nature vs nurture, bio determinism, link between neural differences and APD = complex
          • + support for diathesis stress model, link between crime & frontal lobe
