Psychological Explanations of Crime Learning Criminal Behaviour Psychodynamic Theories Humans are engaged in pleasure seeking behaviors and destructive impulses  Impulses are not regulated due to traumatic childhood experiences  Inner drives, traumatic situations, defenses  5 levels of personality development (oral, anal, phallic, latent, genital  Psychodynamic theories Id = present at birth; unconscious, primitive, instinctual drives PLEASURE PRINCIPLE, no consideration of consequences  Ego = developed to mediate primal needs with society’s demands, REALITY, represses primal needs until a suitable time arises to express it  Superego = internalization of group standards, morality, overseeing our choices CONSCIENCE  Psychodynamic theories Crime is explained by inner impulses  impulses are not adequately controlled harsh, weak or deviant superego Learned Behaviour  Assumptions: people are not born criminal n it is not due to brain injury n neurochemistry or hormonal imbalances are not major factors n mental health problems not a result of biological factors n Learned Behavior  Behaviorism is a scientific process, a scientific strategy as much as a theoretical orientation Classical Conditioning Definition: Type of learning in which an organism develops associations among different events. STIMULUS  RESPONSE Classical Conditioning Ivan Pavlov The Salivary Conditioning of Dogs  Dog   Food Dog Food (Unconditioned Stimulus; UCS) Salivation (Unconditioned Response; UCR)  Dog Food + Tone  Tone   Salivation Salivation Salivation Tone (Conditioned Stimulus; CS) Salivation (Conditioned Response; CR) Classical Conditioning UCS UCR Punished by Parent Discomfort CS UCS UCR Steal a Cookie Punished by Parent Discomfort CS CR Thought of Stealing Cookie Discomfort  So… according to this theory if you have associated a bad feeling to acts of theft, future acts of theft are decreased Behaviorism - Skinner (1904-1990) Operant conditioning Criminal behavior is learned and strengthened because of the reinforcements it brings (we notice the consequence of what happens). People are ultimately determined by the consequences of their environment. Definition of Operant Conditioning Learning in which behaviour is strengthened by reinforcement, or diminished if followed by punishment. Stimuli can be added or subtracted from learner’s environment. Reinforcement is a contingency between response(s) and consequences. 1. Positive Reinforcement 2. Negative Reinforcement 3. Positive Punishment 4. Negative Punishment Extinction – no reinforcement or punishment (most effective way to eliminate behavior according to Skinner). Reinforcement and Punishment REMEMBER: Any event that increases responding is called reinforcement. Any event that decreases responding is called punishment. Any event that is presented is called positive. Any event that is removed is called negative. Comparison of Positive and Negative Reinforcement Positive Negative Follows a behavior Follows a behavior Increases behavior Increases behavior Involves the presentation of a desirable stimulus Involves the removal or avoidance of an unpleasant stimulus Comparison of Positive and Negative Punishment Positive Negative Follows a behavior Follows a behavior Decreases behavior Decreases behavior Involves the presentation of a nondesirable stimulus Involves the removal or avoidance of a pleasant stimulus Process in operant conditioning Behaviour Reinforced Positively Punished Negatively Behaviour occurs more frequently Positively Negatively Behaviour occurs less frequently Types of Operant Conditioning (humans) Positive Negative Pleasant Stimulus Produced Aversive Stimulus Removed Reinforcement Student Receives a Put on Buzzer (increases completes good grade seatbelt stops responding) assignment Aversive Stimulus Produced Pleasant Stimulus Removed Punishment Motorist Receives Teenager Privileges (decreases speed a ticket stays out removed responding) too late (grounded) Operant Conditioning Two basic schedules of reinforcement Continuous Behaviour is reinforced each time it occurs. Intermittent Based on either the passage of time or the number of responses. Intermittent conditioning is the hardest to extinguish (e.g. gambling is based on this principle) Operant Conditioning  Antisocial Behaviour and Reinforcement Prisoners and behavior  Positive Reinforcement  Following the rules to gain access to spousal visits  Negative Reinforcement  Breaking out to escape the aversiveness of being locked up.  Bullying  Positive Reinforcement  Attention from peer onlookers  Tangible reward from victim (e.g., toy)  Negative Reinforcement  A provocative victim withdrawing or ceasing verbal taunts  Behaviorism…plus the adoption of cognition = social learning theory  Cognitive learning   formation of concepts, schemas, theories, attitudes, beliefs, and other mental or abstract versions of the world. Social learning theory  Behaviorism is too simple.  Must examine perceptions, thoughts, expectancies, competencies and values to understand criminality. we learn from observing environment  reinforcement maintains behavior  place greater emphasis on cognitive variables than behaviorists  social learning theory emphasizes cognition!  Social Cognition  Defining social cognition  Social cognition concerns how people make sense of other people and themselves  Processing, interpreting, and communicating information  Thoughts and Attitudes  Moral Reasoning  Attributional Processes Moral Development Kohlberg’s Theory of Moral Development  Cognitive growth  reasoning versus behaviour  We actively construct moral judgments through experiences of social interaction. Moral Development The Case of Heinz and the Druggist: Mr. Heinz's wife is dying. There is one drug that will save her life but it is very expensive. The druggist will not lower the price so that Mr. Heinz can buy it to save his wife's life. What should he do? More importantly, why? Kohlberg’s Stages Level I Stage Orientation 1 Punishment Orientation Pre-Conventional  Right & wrong is determined by what is punished. 2  Instrumental Hedonism Right & wrong is determined by what is rewarded. Kohlberg’s Stages Level II Stage Orientation 3 “Good Boy/Good Girl” Conventional  Right & wrong is determined by close others’ approval or disapproval. 4  “Law & Order” Orientation Right and wrong is determined by society’s rules and law, which should be obeyed rigidly. Kohlberg’s Stages Level III Stage Orientation 5 Social Contract Orientation Post-Conventional  Right and wrong is determined by society’s rules, which are viewed as fallible rather than absolute. 6  Universal Ethical Principle Right and wrong is determined by abstract ethical principles that emphasize equity and justice.

Observational Learning  Observational/Imitational Learning or Vicarious learning (Bandura)  People learn from observing the behaviour of others, and observing the outcomes of that behaviour.  Modeling:  This is where viewers learn behaviours from watching others and may imitate them.  the more respected the model, the greater the impact on our behaviour  It’s not what they say but what they do that is important and the consequences of those actions  the behaviour of model is more likely to be imitated if observer sees model get a reward DON ANDREWS –  Risk, Needs, Responsivity, Treatment Model Developed the Personal, Interpersonal and CommunityReinforcement Model (PIC-R) (Andrews and Bonta) Belief that to truly understand criminal behaviors, we must look at: Antecedents: EVENTS that PRECEDE behaviors AND Consequences: EVENTS that FOLLOW behaviors  Both elements signal rewards and costs for different behaviors  You must look at the big picture!      Media Violence & Aggression  Violence in the media    Friday the 13th film franchise (Body Count = 179) First-person shooter games (Doom, Halo) Case Studies:     14yr old shoots three classmates, inspired by The Basketball Diaries Seven yr old boy accidentally kills his 3 yr old sister by mimicking professional wrestling move seen on TV John Hinckley attempted to assassinate President Ronald Reagan after he watched the movie "Taxi Driver" fifteen times. A gang in Manchester, England, tortured a 16-year-old girl, set her afire and left her dying, while one of the attackers repeated a line from Child’s Play 3: "I’m Chucky– wanna play?" (The New York Times, July 10, 1994) Media Violence & Aggression  The Catharsis Hypothesis   Viewing violence reduces acting out on aggressive impulses Aristotle - - katharsis—    Thought drama allows viewers to identify with the aggression on stage, releasing their own impulses, reducing pressure Freud—good to have an outlet for aggressive drives “blowing off steam”; “getting it out of your system.”  Notion of “blowing off steam” by performing an aggressive act, watching others engage in aggression, or engaging in a fantasy of aggression.  Is this true? Media Violence & Aggression  Correlational Evidence  Meta-analytic Reviews  Average effect sizes ranging from r = .11 to r = .31.  All reviews have found a positive relationship  Greater exposure linked to increases in aggression.  The relationship equivalent to the relationship between smoking and lung cancer  Small to moderate relationship Media Violence & Aggression  Correlational Evidence  Effects of media violence are especially strong in those who:  Are dispositionally aggressive, hostile or irritable  Lack empathy  Younger viewers  Can identify strongly with the aggressive character  Violent scenes are realistic  Violence is portrayed as being justified  Viewers parents do not intervene Media Violence & Aggression  Longitudinal Studies:  Johnson (2002) tracked 700 families for 17 years.  Significant relationship between time spent watching television during adolescence and criminal behavior and interpersonal violence  Independent of parental education, family income, or neighborhood violence Media Violence & Aggression  How does exposure influence aggression?  Influence values and attitudes toward aggression Legitimize aggression  Make aggression seem necessary to solve problems   Habituation or Desensitization Physiological and psychological responses reduced  Desensitizes viewers to pain and discomfort of victims    In the short term, media violence increases aggressive thoughts, physiological arousal, and mimicking In the long term, media violence leads to stable aggression-supporting beliefs, and an aggressive bias when interpreting stimuli/events/interpersonal interactions (Anderson et al., 2004) Social Information Processing  Human behaviour and Social Context  Competent performance in social contexts is a function of the skilful processing of social cues  Encoding and interpreting of cues;  Script retrieval and evaluation; and  Response enactment.  A cue is   A stimulus that provides information about what to do in a particular social situation. WHAT SHOULD I DO? Social Information Processing  Attribution Theory  How individuals use information to arrive at causal explanations for events.  Hostile Attributional Bias (Kenneth Dodge)  The tendency to perceive hostile intent in others even when it is totally lacking.  Some individuals     Define social problems in hostile ways, Adopt hostile goals, Seek few additional facts and generate fewer alternatives Anticipate few consequences for aggression. Social Information Processing  Cognitive Scripts Model (L. Rowell Huesmann)  What are scripts?  Cognitive scripts are mental images or blueprints of how one feels he or she should act in a variety of situations.  Role of Cues and Scripts in Aggression  Observation of aggression  We encode   Aggressiveness of the act and Any relevant pieces of information in the surrounding environment. Social Information Processing  Cognitive Scripts Model (L. Rowell Huesmann)  Can violent media “cue” aggressiveness?  Violent media provides us with scripts that outline - acceptable motives, targets, etc.  An aggressive idea suggested by a violent movie can “prime” other semantically-related thoughts.  Priming is an increase in the speed or accuracy of a decision that occurs as a consequence of a prior exposure to some of the information in the decision context, without any intention or task related motivation Following Authority Figures Moral Disengagement    Through social learning, people internalize moral principles. But, people act against these moral principles to commit crime    Why do people do immoral acts against their own moral judgment when ordered to do so by higher authority or under high social pressures? They do this by “disengaging” from these morals e.g., justifying their behaviour, dehumanizing victims Considering the situation AND the personal attributes of the person in understanding why people do what they do. Deindividuation      Deindividuation (Zimbardo) process of losing ones identity and becoming part of a group, as a situational variable person loses self-awareness lowers restraints regarding antisocial behaviour can be achieved through crowds, masks, uniform, darkness because people more abusive/aggressive when their identity is hidden Situational Determinants  Groups and Aggressive Behaviour  Deindividuation  Social psychology of individual in the crowd  Diminished sense of self and individuality  Zimbardo Prison Study  Prisoners and Guards  Uniforms, Prisoner numbers, Batons Stanford Prison Experiment   The Stanford prison experiment was a study of the psychological effects of becoming a prisoner or prison guard. The experiment was conducted in 1971 by a team of researchers led by psychologist Philip Zimbardo at Stanford University. Twenty-four undergraduates were selected out of 70 to play the roles of both guards and prisoners and live in a mock prison in the basement of the Stanford psychology building. Prisoners and guards rapidly adapted to their roles, stepping beyond the boundaries of what had been predicted and leading to dangerous and psychologically damaging situations. One-third of the guards were judged to have exhibited "genuine" sadistic tendencies, while many prisoners were emotionally traumatized and two had to be removed from the experiment early. After sensing that everyone had been too absorbed in their roles, including himself, Zimbardo terminated the experiment after six days. It was supposed to last 2 weeks. Authority As An Instigator of Criminal Behaviour “Crimes of Obedience” (Kelman & Hamilton) – behaving in certain way b/c someone with power told them they must  An act performed in response to orders from authority that is illegal/immoral by larger community (i.e. – Watergate)  Stanley Milgram - electric shock experiment  Situational Determinants Obedience to Authority  Stanley Milgram   Teacher-Learner Scenario • Experimenter asks participant (“Teacher”) to administer punishment in the form of electric shocks to confederate (“Learner”). • Level of shocks increased at each mistake by 15 volts, from 15 to 450 volts. Situational Determinants  Stanley Milgram  Teacher-Learner Scenario  Learner protests more and more as shock increases  Experimenter continues to request obedience even if teacher balks 120 “Ugh! Hey this really hurts.” 150 “Ugh! Experimenter! That’s all. get me out of here. I told you I had heart trouble. My heart’s starting to bother me now.” 300 (agonized scream) “I absolutely refuse to answer any more. get me out of here You can’t hold me here. Get me out.” 330 “(intense & prolonged agonized scream) “Let me out of here. Let me out of here. My heart’s bothering me. Let me out, I tell you…” Situational Determinants  Experimenter’s Schedule of Prods  Prod 1: “Please continue” or “Please go on”  Prod 2: “The experiment requires that you continue”  Prod 3: “It is absolutely essential that you continue”  Prod 4: “You have no other choice, you must go on” Situational Determinants Percentage of subjects who obeyed experimenter 110 100 90 80 70 60 50 40 30 20 10 0 Slight Moderate Strong (15-60) (75-120) (135-180) Very XXX Intense Extreme Danger: strong (255-300) intensity severe (435-450) (195-240) (315-360) (375-420) Shock levels in works People will follow authority figures and commit acts that go against their moral compass Social factors are very important How do we apply this to gangs, wars, etc… Differential Association Theory It depends on the norms present in the particular groups to which a person belongs. These norms come from the group of friends or families The difference between prosocial attitudes learnt and antisocial attitudes learnt Impact depends on -how often the person interacts with the antisocial attitudes (frequency) -how long the person interacts with the antisocial attitudes (duration) -how early in life the person encounters the antisocial attitudes (priority) -the prestige of the persons who hold the antisocial attitudes (intensity) Peers  The influence of peers on antisocial behaviour with respect to three aspects of peer adaptation:  Seeking acceptance from the peer group  Friendship selection  Friendship interaction Peers  Peer interaction  Modeling and reinforcement of antisocial behavior; Discouraging prosocial attitudes and behavior.  Longitudinal research: associating with delinquent peers was one of strongest predictors of delinquency.
