Humanistic and Biological Perspectives in Psychology

Introduction to Humanistic Psychology

• Conceptual Shift: Humanism arose as a reaction against perspectives suggesting that human behavior is determined solely by previous experiences or internal forces, which imply a lack of free will. Humanists argue that individuals possess free will.

• Criticism of Earlier Models: Humanists took offense at figures like Freud who focused primarily on neurotic individuals. They argued that to understand human potential, it is necessary to study the very best examples of humanity.

• Optimistic View of Human Nature: Humanism posits that people are by nature good. Unlike earlier philosophies that suggest humans are inherently bad and require socialization to be controlled, humanism suggests a natural tendency to:

  • Better and enhance oneself.

  • Flourish.

  • Develop a concern for others that goes beyond personal needs.

The Analogy of the Flower and Environment

• Growth and Flourishing: A flower will grow and flourish as long as its basic needs are met. If it is deprived of essential elements like food, water, or sunlight, it will fail to thrive.

• Human Application: Humanists believe the same principle applies to people. Given the right conditions, people will flourish. Bad behavior is perceived as a result of being deprived of important needs or living in a negative environment.

• Major Theorists: The two primary figures behind the humanist movement are Abraham Maslow and Carl Rogers.

Subjective Reality and Perspective

• Perception of Reality: Humanism emphasizes that everyone perceives and interprets the world differently. Because of this subjective experience, it is not useful to compare a person's perspective to an "objective" reality.

• Clinical Application: In therapy, particularly the approach used by Carl Rogers, it is essential for the therapist to understand the patient’s specific point of view rather than applying an objective external lens.

Abraham Maslow’s Hierarchy of Needs

• Multidisciplinary Impact: Maslow's theories are studied in psychology, education, business, and sports.

• Hierarchy Structure: Maslow believed people are motivated by a hierarchy of needs where lower-level needs must be satisfied before an individual can be motivated by higher-level needs.

• Five Levels of Needs:

  1. Physiological Needs: The lowest level, includes basic survival necessities like food and water. If an individual is starving, they cannot focus on higher motivations.

  2. Security Needs: Once physiological needs are met, the focus shifts to security, which in modern society includes having a job, income, and a roof over one’s head.

  3. Social Needs: This involves a sense of belonging and acceptance. It is fulfilled through connections with loved ones, friends, family, churches, and community organizations.

  4. Esteem Needs: This includes both the respect and acknowledgment of others and self-respect (self-esteem). Individuals seek fulfillment, purpose, and a sense of being "good" at something.

  5. Self-Actualization: The highest level, representing being the very best version of oneself. At this stage, having met personal needs and resolved psychological discomfort, the individual focuses on the needs of society, such as fighting injustices or improving the world.

Self-Actualization Specifics

• Prevalence: Only about $1\%$ of the population is believed to reach self-actualization.

• Named Examples: Maslow identified individuals like Albert Einstein and Thomas Jefferson as self-actualizers. Others often cited include Mother Teresa, Martin Luther King Jr., and Mahatma Gandhi.

• Obstacles: Most people do not reach this stage because societal obstacles prevent lower-level needs from being consistently met.

• The Power of Lower Needs: Lower needs have more power over motivation. If someone loses their job (security need), they will stop worrying about higher-level aesthetics or philosophy and focus on finding new employment.

Case Study: Abraham Maslow

• Genius IQ: Maslow was a genius with an IQ score described as occurring only in one in millions.

• Early Academic Struggles: Despite his intelligence, he initially dropped out of college. He came from a horrific, abusive household and lacked love and belonging.

• The Turning Point: His motivation to succeed only emerged after he got married. The fulfillment of his social needs (love/acceptance) allowed him to pursue esteem needs (academic success and peer respect).

• Achievement: He eventually became the president of the American Psychological Association (APA).

Characteristics of Self-Actualizers

• Self-Acceptance: They are transparent, non-defensive, and do not hide their limitations.

• Present Focus: They live in the moment rather than worrying about the past or future.

• Spontaneity and Compassion: They are spontaneous and have deep concern for others.

• Open-Mindedness: They are not limited by prejudice or discrimination; they are creative and able to see fresh perspectives on unique insights.

• Antisocial Behavior: Maslow argued that antisocial behavior (e.g., joining a gang) results from unmet social needs; the gang provides the sense of belonging that the individual was deprived of elsewhere.

Carl Rogers and Person-Centered Therapy

• Revolutionary Approach: Rogers changed therapy by making it "client-led" rather than having the therapist act as an authority figure.

• The Three Selves:

  • Ideal Self: The version of one’s self they would like to be.

  • Real Self: The sense of who the person actually is.

• Incongruence: This is the gap or disparity between the real self and the ideal self. Rogers observed that the wider this gap, the greater the anxiety and mental distress experienced by the patient.

• Congruence: This occurs when there is consistency and the two selves match.

Development of Incongruence

• Need for Positive Regard: Children have an innate need for love and acceptance from parents.

• Unconditional Positive Regard: Children are made to feel they are loved no matter what, even when they make mistakes. This separates their behavior from their identity.

• Conditional Positive Regard (Conditions of Worth): Love is only given if the child behaves in a certain way or achieves specific goals (e.g., straight A's). This creates "conditions of worth."

• Adult Outcomes: Adults raised with conditions of worth carry that mentality into adulthood. They may become:

  • Defensive.

  • Distorted in their reality to maintain a fictional narrative of never failing.

  • Risk-averse due to fear of failure or rejection.

Alfred Adler’s Individual Psychology

• Neo-Freudian Background: Adler was part of Freud’s inner circle but was eventually cast out over disagreements. He rejected Freud's universal principles (e.g., dream symbols having fixed meanings) and focused on the uniqueness of the individual.

• Superiority and Inferiority: Adler believed it is a normal human experience to feel inferior as we grow up.

• Compensation: The healthy way to deal with inferiority is to compensate by finding something one is good at or working to improve the area of inferiority.

• Inferiority Complex: This occurs when an individual fails to compensate healthily and becomes permanently fixated on their flaws, leading to a persistent feeling of being unequal to others.

• Social Interest: A vital part of a healthy personality involving concern for others and empathy.

  • Low Social Interest: Individuals with an inferiority complex are internally focused on personal success to prove they aren't failures.

  • High Social Interest: Healthy individuals collaborate with others and view success through their positive impact on the community.

• Birth Order: Adler famously proposed that birth order (firstborn, middle, youngest, only child) significantly impacts personality and life outcomes.

Karen Horney’s Neurotic Behaviors

Note: While the speaker describes these behaviors as "the three main behaviors of neurotics," these specifically refer to Karen Horney's theory regarding safety needs in childhood.

• Moving Toward People: The individual becomes super compliant and submissive. They have a desperate need for acceptance and cannot bear rejection or being alone.

• Moving Against People: The individual is aggressive and seeks to prove their worth by tearing others down, pointing out the flaws of others to make themselves look superior.

• Moving Away From People: The individual believes they are unworthy of love and decides they do not need anyone. They become detached, super independent, and live a solitary life within narrow boundaries.

Biological Perspectives on Personality

• Nature vs. Nurture: While the early part of the lecture focuses on nurture, there is a significant biological component to personality.

• Temperament: These are early-appearing behavioral tendencies observable shortly after birth. Dimensions include:

  • Reactivity: How an infant responds to the environment (curiosity vs. withdrawal).

  • Self-Regulation: The ability to control emotional responses and impulses.

• Brain Mechanisms:

  • Neuroticism: Linked to larger and more active brain regions associated with negative emotion and anxiety.

  • Extroversion: Linked to a higher density of dopamine receptors, explaining their enthusiasm and social behavior.

Heritability and Twin Studies

• Heritability Definition: A statistical measure between $0$ and $1$ that indicates how much of the variance in a trait is due to genetics. Personality typically scores around $0.5$ ($50\%$).

• Twin Study Findings:

  • Identical twins (share $100\%$ genes) are much more similar in personality than fraternal twins (share $50\%$ genes), even when raised in the same house.

  • Minnesota Twin Study: Conducted on identical twins separated at birth. They showed high similarity (heritability above $0.5$) in traits like traditionalism, obedience to authority, and fearfulness.

• Environment Types:

  • Shared Environment: Factors shared with siblings (e.g., parenting style). Psychology research suggests this is less influential than people assume.

  • Non-Shared Environment: Unique personal experiences and peer groups. This is far more important in shaping personality.

• Epigenetics: The study of how environment triggers or activates certain genes.

  • Depression/Schizophrenia: Two people may have the same genetic vulnerability, but it may only be triggered by specific stressors or neurotoxins (e.g., a toxin in cat litter linked to schizophrenia).

  • Aggression: A genetic vulnerability for aggression may only be activated if the individual experiences childhood abuse.

Mathematics of Intelligence (IQ) and Heritability

• Nature's Role in IQ: Research shows a strong genetic component to intelligence.

  • Identical twins raised together: Similarity of $0.85$.

  • Identical twins raised apart: Similarity of $0.72$ to $0.75$.

  • Fraternal twins raised together: Similarity of $0.60$.

  • Siblings raised together: Similarity of $0.44$ to $0.46$.

  • Unrelated (adopted) children raised together: Similarity of $0.20$ to $0.32$.

• Global Estimate: The heritability of IQ is thought to be at least $60\%$.

• Environmental Impact on IQ:

  • Severe malnourishment, sensory deprivation, and social isolation negatively affect brain development and IQ.

  • Romanian Orphanage Study (1980s): Children in overrun orphanages who were malnourished and socially deprived suffered long-term consequences in cognitive and social development, including lower IQ and attachment issues.
