Forensic Psychology: Applications, Types of Offenders, and Psychological Assessment

Forensic Psychology: An Overview

Approaches to Criminological Knowledge

  1. Criminal Personality
  2. Criminogenic Society
  3. Interactionist Perspective (Justice System as a potential source of violence)
  4. Victimological Approach
  5. Preventive Approach

Victimology

Defined in 1973 as the scientific study of victims, particularly victims of crime.

Understanding Obsessions

Obsessions are intrusive, repetitive thoughts that a person recognizes as irrational but cannot control. Types of obsessions include:

  • Obsessive thoughts: Intrusive words or phrases.
  • Obsessive doubts: Uncertainty about previous actions.
  • Obsessive impulses: Urges to perform actions that are often aggressive, dangerous, or embarrassing.

Classification of Mental Disorders (DSM-IV)

The DSM-IV uses a multiaxial system to diagnose mental illness across five axes:

  • Axis I: Clinical disorders (excluding personality disorders and mental retardation).
  • Axis II: Personality disorders and mental retardation.
  • Axis III: Relevant medical conditions.
  • Axis IV: Psychosocial and environmental problems.
  • Axis V: Global Assessment of Functioning (GAF).

Psychopathy vs. Sociopathy

Psychopathy

Psychopaths have difficulty controlling antisocial impulses due to a possible biological basis. Socialization processes have little effect on their behavior.

Sociopathy

Sociopaths develop antisocial behavior due to inadequate socialization and parenting, rather than inherent biological factors.

Antisocial Personalities

Characterized by a persistent pattern of antisocial behavior. Sociopaths, the largest group, often lack empathy and have experienced incompetent parenting. Some exhibit aggression, fearlessness, sensation-seeking, or manipulative tendencies.

Subtypes of Sociopathic Personality

  1. Common Sociopath: Resulting from poor parenting and negative social environments.
  2. Alignment Sociopath: Characterized by a failure of empathy and difficulty forming attachments.
    • Unaffiliated: Lack of affective fitness due to neglectful parenting.
    • Disempathic: Restricted circle of empathy, treating most people as objects.
    • Hostile: Repudiate society and exhibit hostility due to alienation or inability to achieve goals.
    • Swindled: Rationalize antisocial behavior by believing societal rules don’t apply to them.
  3. Aggressive Sociopath: Derive satisfaction from dominating and harming others.
  4. Sociopathic Conduct: Normal individuals who adopt the predatory subculture of gangs or terrorist groups.

Psychopathy in Detail

Psychopathy is a nonspecific term indicating a psychological source of conduct disorder. Popularly, it’s associated with heinous crimes, but the technical definition differs.

Subtypes of Psychopathy

  1. Temperamental Psychopaths (Organic Episodes): Well-socialized individuals experiencing episodic organic disorders that affect emotional and mental stability.
  2. Choleric Temperament Psychopaths: Prone to anger and aggression.
  3. Hypersexual Psychopaths: Exhibit an excessive preoccupation with sexual urges.
  4. Anxious Psychopaths: Find reinforcement in criminal activity to alleviate anxiety.
  5. Hysterical Psychopaths: Display psychopathic tendencies intermittently, lacking consistent feelings of apprehension or remorse.

Primary vs. Secondary Psychopathy

  • Primary Psychopaths: Choose crime as an occupation, lacking empathy and remorse. They often come from stable backgrounds and resist socialization efforts.
  • Secondary Psychopaths: Similar to primary psychopaths but experience guilt and introversion.
