    Study Notes

    Emotions and Physical Reactions

    • Emotions influence physiological functions such as blood pressure, heart rate, muscle tension, and hormonal secretions.
    • Operational definitions in research require clarity on sample size, demographics, and causal claims.

    Understanding Personality

    • Personality consists of consistent and distinct characteristics, emotional responses, thoughts, and behaviors.
    • It is a habitual way of responding, independent of social pressures.
    • Self-awareness and others' perceptions of an individual can differ.

    Approaches to Personality

    • Various theories provide differing views on the nature of personality—some positive, others negative.
    • Some theories focus on categorizing behaviors, while others highlight the role of individual agency in personality construction.

    Trait Approach to Personality

    • Focuses on descriptive labels to understand and predict behaviors.
    • Traits are stable dimensions reflecting individual differences, identified through factor analysis of adjectives.
    • Traits like "moody" can be categorized under broader traits, such as neuroticism.

    The Big Five Personality Traits

    • Extraversion: Orientation toward social interactions; high traits are sociable, low are reserved.
    • Neuroticism: Stability of emotions; high traits are anxious, low are calm.
    • Conscientiousness: Dependability and discipline; high traits are organized, low are careless.
    • Agreeableness: Cooperativeness and kindness; high traits are trusting, low are suspicious.
    • Openness: Creativity and variety-seeking; high traits are imaginative, low are conventional.
    • The Big Five traits are consistent across cultures and age groups.

    Social-Cognitive Approach

    • Emphasizes self-perception and expectations about social interactions.
    • Pessimistic explanatory styles view failures as pervasive and permanent, while grit involves persistence for long-term goals.

    Freudian Perspective on Personality

    • Freud's theory posits that early childhood experiences shape personality in a deterministic manner.
    • Personality development involves navigating psychosexual stages that influence adult behavior.
    • Freud emphasized the unconscious, where repressed desires and conflicts reside, impacting behavior through defense mechanisms.

    Genetic Influences on Personality

    • About 40% of personality trait variability is attributed to genetics.
    • Personality traits exhibit stability over time, with changes possible through focused efforts.

    Brain Functions and Structure

    • The brain is a specialized organ with distinct areas responsible for specific psychological functions.
    • Research methods include studying individuals with brain damage, brain scans, and animal models.

    Major Brain Structures

    • Hindbrain: Oversees basic life functions like breathing and heart rate through structures like the medulla and cerebellum.
    • Limbic System: Associated with emotion, motivation, and memory; includes the thalamus, hypothalamus, hippocampus, and amygdala.
    • Cerebral Cortex: Responsible for complex functions like perception and thought, with four lobes—occipital, parietal, temporal, and frontal.

    Specific Brain Lobes

    • Occipital Lobe: Primarily involved in vision processing.
    • Parietal Lobe: Processes touch and spatial orientation; damage can lead to hemineglect.
    • Temporal Lobe: Key for hearing, language, and object memory, including face recognition (prosopagnosia).
    • Frontal Lobe: Essential for planning, decision-making, emotions, and behavior regulation.

    Nervous System Overview

    • The nervous system consists of neurons that process and relay information throughout the body.
    • Neurons communicate via electrical impulses (action potentials) and chemical signals across synapses.

    Neuron Communication

    • Dendrites receive signals that influence neurons' electrical state, leading to depolarization (triggering action potentials) or hyperpolarization.
    • The myelin sheath enhances the speed of electrical impulses along the axon.
    • Action potentials involve a rapid change in electrical charge across the neuron, influencing neighboring sections in a domino-like effect.
