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.
