    Study Notes

    Evolutionary Perspectives

    • Producing offspring is the single most important factor in natural selection.
    • Psychological adaptations are designed to accomplish particular adaptive goals.

    Sex Differences

    • Males and females have differences in parenting investment due to biological functions.
    • Males who are highly desirable can expect a high future reproductive rate, but females partially select males for their willingness to invest in parenting.

    Life History Theory

    • Life requires capturing (foraging/hunting/cultivating) and allocating (reproduction and survival-enhancing activities) energy.
    • The mating effort-parental effort trade-off is a key aspect of Life History Theory.
    • Knowledge of the environment and environmental pressures influence individuals' decision-making processes about the allocation of resources.
    • LHT describes the adaptive choices made by individuals to optimize reproduction and survival based on the environment.

    LH Strategies

    • There are different life strategies, such as slow and fast strategies, which are influenced by the environment.
    • Slow strategies are characterized by a stable, consistent environment, where resources are allocated preferentially to somatic effort over reproductive effort.
    • Fast strategies are characterized by an unstable, unpredictable, harsh environment, where resources are allocated to reproductive effort over somatic effort.
    • Examples of slow strategies include elephants, while examples of fast strategies include rabbits.

    Human Nature

    • Human nature is characterized by the need to belong, and we cannot survive on our own.
    • Helping and altruism are universal emotions that are essential for survival.
    • Bad emotions have more influence and importance than good emotions, as being aware of negatives facilitates survival.

    Environmental Triggers

    • Environmental triggers, such as father absence, can direct individuals towards short-term mating strategies.
    • Heritable individual differences are contingent on other traits, such as individuals who are muscular and large pursuing more aggressive strategies.

    Preparedness Hypothesis

    • The preparedness hypothesis suggests that certain things in our ancestral past posed a real threat to our survival or the survival of our offspring.
    • Examples of this include the development of fears of certain things, which led to increased survival and reproduction.

    Offspring

    • The quantity-quality trade-off of offspring refers to the decision between having a lot of offspring or investing strongly in the offspring you do have.
    • Energy allocated to growth now reduces fertility at younger ages, but increases at older ages.

    Disorders of Personality

    • A psychological disorder is a pattern of behavior or experience that is distressing and painful to the person, leading to disability or impairment in important life domains, and associated with increased risk for further suffering, loss of function, death, or confinement.
    • The concept of disorder is tentative and subject to change as society changes.
    • The field of psychopathology, or the study of mental disorders, combines statistical, social, and psychological approaches to abnormality.

    The Diagnostic and Statistical Manual of Mental Disorders (DSM-5)

    • The DSM-5 is the most widely used system for diagnosing mental disorders, including personality disorders.
    • The DSM-5 maintains a categorical model of personality disorders, with 10 specific disorders.
    • The DSM-5 includes a section (Section III) that describes areas needing further research.

    What Is a Personality Disorder?

    • A personality disorder is an enduring pattern of experience and behavior that differs greatly from the expectations of the individual's culture.

    Specific Personality Disorders

    The Erratic Cluster: Ways of Being Unpredictable, Violent, or Emotional

    • Disorders in this cluster include antisocial, borderline, histrionic, and narcissistic personality disorders.
    • People with these disorders tend to have trouble with emotional control and difficulties getting along with others.

    Antisocial Personality Disorder

    • The antisocial person shows a general disregard for others and cares little about the rights, feelings, or happiness of others.
    • Childhood behavioral problems, such as violating the rights of others or breaking age-related social norms, are common among individuals with antisocial personality disorder.
    • Adults with antisocial personality disorder typically had a childhood marked by behavioral problems, which worsened as they developed physically, cognitively, and sexually.
    • Key features of antisocial personality disorder include:
      • Lack of concern for social norms
      • Repeated lying
      • Impulsivity
      • Irritability and aggression
      • Recklessness
      • Irresponsibility
      • Lack of remorse and guilt feelings
      • Indifference to the suffering of others

    Borderline Personality Disorder

    • The lives of persons with borderline personality disorder are marked by instability in relationships, behavior, emotions, and self-image.
    • Key features of borderline personality disorder include:
      • Intense, emotional, and potentially violent relationships
      • Strong fears of abandonment
      • Marked difficulties in relationships
      • Shifting views of oneself
      • Self-harming acts
      • Strong emotions, such as panic, anger, and despair, often caused by interpersonal events.
