Forensic Psychology: Study Notes

AQA A-Level Psychology - Essay Plans

Overview of Essay Plans
  • One essay plan per topic allows students to answer every possible question.
  • Creating multiple essay plans for each possible question would lead to information overload.
  • Proposed essay plans simplify this by being generalizable to different questions related to each subtopic.
Example: Caregiver-Infant Interactions

  1. AO1 Points (6 total)

    • Reciprocity
    • Interactional synchrony
    • Meltzoff and Moore’s research
    • Isabella et al’s research

  2. AO3 Points (4 total)

    • Emphasis on the importance of evaluating evidence supporting or contradicting these concepts.

  3. Application of Essay Plans:

    • For questions that require outlining and evaluating specific interactions, select AO1 and AO3 points from the plan.
    • If research studies are necessary to achieve full marks, they should be included in the AO1 section.
    • Reiterate specific definitions when asked for brief definitions of key terms.
Approach to Questions
  • Prepare by identifying relevant points from the essay plans based on the specific question prompt stated in the exam.

Offender Profiling: The Top-Down Approach

Definition of Offender Profiling
  • A behavioral and analytical tool used to narrow down a list of suspects.
  • Involves analyzing crime scenes and other evidence (witness reports, etc.) to hypothesize offender characteristics.
Top-Down Approach
  1. Origin and Development
    • American method developed by the FBI through interviews with 36 sexually motivated murderers.
    • Introduced categories: organized and disorganized offenders.
Characteristics of Offenders
  • Organized Offender:
    • Planned crime, targeted victim.
    • High control during crime, above-average IQ, often married.
  • Disorganized Offender:
    • Spontaneous crime, impulsive.
    • Below average IQ, may live alone.
Constructing an FBI Profile
  1. Data assimilation: Review evidence (photos, pathology reports).
  2. Crime scene classification: Identify if crime is organized or disorganized.
  3. Crime reconstruction: Develop behavioral hypotheses.
  4. Generation of the offender profile: Background and physical characteristics.
AO3 Evaluation of Top-Down Approach
  • Strength:
    • Evidence from Canter's analysis showed distinct organized offenders.
    • Found behaviors matched typologies of organized offenders.
  • Limitation:
    • More applicable to severe crimes (like murder) than common crimes (like burglary).
    • Simplistic classification does not account for mixed behaviors.

Offender Profiling: The Bottom-Up Approach

Definition of the Bottom-Up Approach
  • A British approach focusing on constructing profiles based on crime scene evidence.
Key Components

  1. Investigative Psychology:

    • Statistical analysis to detect behavioral patterns.
    • Interpersonal coherence suggests that offender behavior might reflect everyday interactions.

  2. Geographical Profiling:

    • Crime mapping to infer offender's home base or operational areas.
    • Circle theory suggests crime locations form a circle around offender’s home base.
AO3 Evaluation of Bottom-Up Approach
  • Strength:
    • Scientific credibility through quantitative data analysis.
  • Limitation:
    • Reliance on solved cases; restrictions can limit understanding non-typical crimes.

Historical Biological Explanations

Lombroso’s Theory of Atavistic Form
  • Offenders seen as genetic throwbacks with identifiable atavistic characteristics.
  • Key physical traits include:
    • Narrow brow, strong jaw, high cheekbones.
    • Other traits: Insensitivity to pain, tattoos, etc.
  • Lombroso's findings indicated that 40% of criminal acts were associated with physical atavistic traits.
AO3 Evaluation of Lombroso's Theory
  • Strength:
    • Pioneered scientific approach to criminology.
  • Limitation:
    • Socially sensitive implications leading to prejudice; findings challenged by later research.

Genetic and Neural Explanations

Genetic Factors in Criminality
  1. Twin Studies: Concordance rates (35% MZ twins, 13% DZ twins) indicate a genetic component.
  2. Candidate Genes: Genes MAOA and CDH13 associated with violent behavior.
Neural Explanations
  • Evidence suggests structural differences in the brains of offenders, showing links between brain activity and criminal behavior.
AO3 Evaluation of Genetic and Neural Explanations
  • Strength: Supports the biological basis of certain criminal behaviors.
  • Limitation: Reductionist; does not account for environmental influences.

Psychological Explanations

Eysenck’s Theory of Personality
  • Personality dimensions: Extraversion-Introversion, Neuroticism-Stability, Psychoticism-Sociability.
  • Criminal Personality: A combination of high extraversion and neuroticism leads to impulsive criminal behavior.
AO3 Evaluation of Eysenck’s Theory
  • Strength: Validity due to empirical research.
  • Limitation: Overemphasizes biological determinism and cultural bias.

Cognitive Explanations of Offending Behavior

Levels of Moral Reasoning (Kohlberg)
  • Outlines developmental stages and their correlation to offenses.
  • Offenders typically display lower levels of moral reasoning.
Cognitive Distortions
  • Focused on faulty thinking patterns like hostile attribution bias and minimalization, justifying criminal behaviors.
AO3 Evaluation of Cognitive Explanations
  • Strength: Positive applications in therapy (CBT).
  • Limitation: Descriptive rather than explanatory.

Dealing with Offending Behavior

Custodial Sentencing
  • Aims: deterrence, incapacitation, retribution, rehabilitation.
  • Psychological effects: stress, depression, institutionalization.
  • Recidivism rates illustrate effectiveness in reducing reoffending.
Behavior Modification Techniques
  • Based on operant conditioning; token economies reward positive behavior.
Anger Management Programs
  • Utilize cognitive-behavioral techniques to manage anger triggering situations.
Restorative Justice
  • Focus on healing and reparation rather than punishment.

Evaluation Tips for Writing Essays

  • PEEL structure for evaluations (Point, Evidence, Explain, Link).
  • Address the application's implications and reflect on the strengths and weaknesses of theories and methods.

Conclusion

  • Solid understanding of diverse theories and practical applications is essential for essays in forensic psychology.
