Psychology Hare Psychopathy Checklist-Revised (PCL-R) Instrument used by trained clinicians. Assesses 20 symptoms associated with psychopathy. Each symptom is scored from 0 – 2 (0 = definitely does not apply to the person, 2 = definitely does apply to the person). Consists of 2 factors: Affective/interpersonal features and behavioural features. Maximum score: 40. A score of 30 is indicative of the presence of psychopathy.

Each symptom is scored from 0 – 2 (0 = not present; 2 = item definitely applies). Consists of 2 factors: Affective/interpersonal features and behavioural features. Maximum score: 24. A score of 18 is indicative of the presence of psychopathy.

Psychology Questions That Will be Answered in Today’s Lecture Psychoanalytic Perspective on Personality 1. Who was Sigmund Freud and what events in his life influenced his thinking about personality? 2. According to psychoanalytic theory: (a) what are the major components of the mind?

Psychology Who was Sigmund Freud and what events in his life Born in Austria in 1856, at the end of the Romantic Period and the start of the Victorian Era. Romantic Period influenced his thinking about personality?  Characterized by rejection of reason, order, and concern for common good.  Emphasized “passionate living.”

Psychology Victorian Era  Characterized by a scientific and rational view.  Emphasized morality (in particular, repression of sexuality), duty, and a need for social reform. The ideals of both the Romantic Period and the Victorian Era appear to have had a substantial influence on Freud’s thinking.

Psychology Consistent with the ideals of the Romantic Period, Freud suggested that people experience emotional and irrational impulses—in particular, emotional and irrational impulses related to sex and aggression. Consistent with the ideals of the Victorian Era, Freud suggested that the emotional and irrational impulses that people experience must be restrained or expressed indirectly in order for society to function effectively.

Psychology Indeed, the 2 aspects of human experience that Freud emphasized in psychoanalytic theory are: (a) the emotional and irrational impulses that people experience. (b) the mechanisms that people use to restrain or redirect these impulses. There are 7 individuals who had a noteworthy impact on Freud’s thinking:

Psychology Amalie Freud  Freud’s mother.  Freud described his feelings for his mother as the purest and least ambivalent of all of his emotional experiences.

Psychology Jacob Freud  Freud’s father.  Freud described his feelings for his father as highly ambivalent, characterized by both love and hate.

Psychology  Freud’s unfettered love for his mother and ambivalence for his father are likely to be the source of his ideas regarding the Oedipus Complex (will discuss later in class).

Psychology Ernst Brucke  A physician and physiologist under whom Freud studied when he began university (1873).

Psychology  Brucke introduced Freud to the mechanist perspective. According to this perspective, biological systems are best represented by machine models (i.e., models that use energy).  Freud adopted this perspective: Freud theorized that the mind is a system that transforms raw psychic energy into work (i.e., thought and behaviour).

Psychology Josef Breuer and Jean-Martin Charcot BreuerCharcot

Psychology  Unconventional scientists who studied “hysteria.” This condition is characterized by symptoms such as paralysis, visual/speech/auditory disturbances, hallucinations, and multiple personalities.

Psychology  Charcot demonstrated that hysteria had psychological origins (e.g., demonstrated that the symptoms could be created or removed under hypnosis).  Breuer discovered that the symptoms could be removed by talking about their origins. Breuer referred to this remedy as the “talking cure.”  Freud adopted Charcot’s procedure for inducing hypnosis and Breuer’s talking cure in his own work with hysterical patients.

Psychology Emmy Von N.  A patient of Freud’s who suffered from hysteria.  Freud attempted to treat her symptoms using hypnosis and the talking cure but was unsuccessful.  During treatment, Emmy Von N. suggested that Freud allow her to speak freely, without interruption.

Psychology  On the basis of Emmy Von N.’s suggestion, Freud developed the therapeutic technique of free association, the “fundamental rule” of psychoanalysis.  Following from his work with patients such as Emmy Von N., Freud co-authored “Studies in Hysteria,” in which he argued that hysterical symptoms are caused by problems in memory associated with traumatic childhood events.  Many scholars believe that this book marks the birth of psychoanalytic theory.

Psychology Wilhelm Fleiss  Freud’s closest confidant in the early 1900s.  In early correspondence with Fleiss, Freud wrote extensively about seduction theory. In this theory, Freud argued that the symptoms associated with hysteria are the result of repressed memories of childhood sexual abuse.  Later, however, Freud abandoned seduction theory, arguing that the sexual abuse of children was not common enough to account for the high prevalence of hysteria.

Psychology  After abandoning seduction theory, Freud came to believe that, in many cases, hysterics fantasized that they had engaged in sexual relations as children.  Many scholars believe that this revelation marks the point at which Freud began to explore the dynamics of the unconscious mind.

Psychology According to psychoanalytic theory, what are the major components of the mind? Freud believed that the mind is comprised of 3 major components or regions. The 3 components reflect different levels of consciousness. The 3 components are represented in Freud’s Topographical Model of the Mind. According to this model, the 3 components are as follows:

Psychology The conscious component of the mind  Makes up the surface area of the brain.  Contains information that an individual is currently aware of.

Psychology The preconscious component of the mind  Below the conscious component of the mind.  Contains information that an individual is not currently aware of but can readily retrieve and bring into conscious awareness.

Psychology The unconscious component of the mind  Below the preconscious component of the mind.  Contains information that an individual cannot readily retrieve—information that has been actively repressed because it is too threatening to bring into conscious awareness.  This information is expressed largely in symbolic form (e.g., through dreams). Thus, the information continues to influence the individual.
