Lie Detection

  • Polygraph
      - Measures physiological arousal (e.g., heart rate, sweat).
      - Cannot directly detect lying; only indicates physiological responses that may correlate with deception.
  • fMRI (Functional Magnetic Resonance Imaging)
      - Tracks brain activity, providing a more scientific method of investigation.
      - Still debated regarding reliability and ethical concerns.
  • Microexpressions
      - Quick, involuntary facial expressions that might reveal underlying emotions.
      - Can indicate deceit but are not foolproof and often require training to interpret.
  • Key Idea
      - No lie detection method is perfectly reliable, highlighting the complexity of human behavior and communication.

Intelligence

  • Definition
      - Intelligence defined as the ability to adapt, think critically, and solve problems effectively.
  • g Factor
      - Refers to general intelligence that applies across multiple tasks and domains.
  • Gardner's Theory of Multiple Intelligences
      - Proposed multiple forms of intelligence including:
        - Linguistic
        - Logical-Mathematical
        - Musical
        - Intrapersonal
        - Interpersonal
        - Naturalistic
        - Bodily-Kinesthetic
        - Spatial
  • IQ (Intelligence Quotient)
      - Average score set at 100.
      - Follows a bell curve distribution in the population.
  • Nature vs. Nurture
      - Intelligence shaped by both genetic (nature) and environmental (nurture) factors, with ongoing debates about their respective influences.

Ambiguity in Language

  • Definition of Ambiguity
      - Occurs when language presents multiple meanings, leading to confusion or misinterpretation.
  • Types of Ambiguity
      - Lexical Ambiguity
        - Occurs when a word has multiple meanings (e.g., "bat" as in the animal or sports equipment).
      - Syntactic Ambiguity
        - Arises from sentence structure leading to different interpretations (e.g., "I saw the man with the telescope" can imply different subjects).
      - Phonological Ambiguity
        - When words sound alike but have different meanings (e.g., "to, two, and too").

Social Psychology

  • Definitions
      - Stereotypes: General beliefs about a group.
      - Prejudice: Emotional responses or attitudes toward a group.
      - Discrimination: Actions or behaviors based on prejudices.
  • Implicit Association Test (IAT)
      - Measures unconscious bias by assessing reaction times to paired concepts, revealing implicit attitudes toward different social groups.
  • Bandura's Bobo Doll Study
      - Demonstrated that aggression can be learned through observation and imitation of others, highlighting the role of social learning in behavior.
  • Bystander Effect
      - Phenomenon where individuals are less likely to help a victim in the presence of others.
  • Diffusion of Responsibility
      - The assumption that others will take action, leading to inaction among witnesses in emergency situations.

Development

  • Attachment
      - Defined as the emotional bond between a child and their caregiver, crucial for emotional development.
  • Harlow's Experiments
      - Showed that comfort and emotional security are often more important than basic needs such as food in fostering attachment.
  • Strange Situation
      - A method developed by Mary Ainsworth to identify different styles of attachment in children:
        - Secure
        - Avoidant
        - Ambivalent

Personality

  • Freud's Theory of Personality
      - Emphasized the role of unconscious drives in shaping behavior.
      - Components:
        - Id: Represents impulses and desires.
        - Ego: Mediates reality, balancing the Id and Superego.
        - Superego: Represents morality and societal rules.
  • Defense Mechanisms
      - Psychological strategies used by the ego to protect itself from anxiety, including:
        - Denial
        - Repression

Motivation

  • Drives
      - Biological needs that motivate behavior, such as hunger and thirst.
  • Maslow’s Hierarchy of Needs
      - Organizes human motivations into a five-level hierarchy, progressing from basic physiological needs to self-actualization:
        1. Physiological Needs
        2. Safety Needs
        3. Love/Belonging Needs
        4. Esteem Needs
        5. Self-Actualization

Abnormal Psychology

  • Classification
      - Disorders classified using the DSM (Diagnostic and Statistical Manual of Mental Disorders).
  • Causes of Disorders
      - Can include a combination of biological, psychological, and social factors.
  • Common Disorders
      - Anxiety Disorders
      - Mood Disorders
      - Schizophrenia
  • Treatment Approaches
      - Often involves a combination of therapy and medication for effective management.

Key Exam Themes

  • Behavioral Insight
      - Behavior is influenced more by situational factors than inherent personality traits.
  • Implicit Biases
      - Exist in individuals, but strategies can be derived to control or mitigate these biases.
  • Nature and Nurture Interaction
      - Always interacts; both components are essential in shaping various psychological traits and behaviors.
  • Statistical Significance
      - Small statistical effects can still have significant implications over time, particularly in large populations.
