Schools of Psychology
-
Structuralism: A school of psychology whose goal was to identify the basic elements or structures of the mind.
- Founded by William Wundt.
- Breaks downs mental processes into their smallest possible components and analyses them.
- Rigorous and scientific.
- Utilizes introspection, asking research participants to describe what they experience as they work on mental tasks.
- Limitations: Participants' inability to report experiences due to their unconscious mind.
-
Functionalism: Focused on the purpose and function of human thoughts and subsequent behaviors.
- Focused on the higher purpose of consciousness and behavior.
- The core idea of mental states (beliefs, pain, desire) are only present for their functional role.
- Limitations: No longer in use now, we can’t determine which psychological characteristics our ancestors had.
-
Structuralism vs. Functionalism:
- Structuralism: Structure of the mind.
- Functionalism: Function of the mind.
- Structuralism: Primary method: Introspection.
- Functionalism: Focused on application.
Psychodynamic Psychology
- An approach to understanding human behavior that focuses on the role of unconscious thoughts, feelings, and memories.
- Founded by Freud.
- Early childhood experiences are the most important factor in human development.
- Conscious: Thoughts, perceptions.
- Preconscious: Memories, stored knowledge.
- Unconscious: Instincts, fears, trauma, violence.
-
Freud states that personality is composed of three elements:
- Id: Part of the mind that wants instant gratification and acts upon basic desires.
- Ego: Balances id desires with reality by making rational desires.
- Superego: A conscience, reminds us of societal roles and morals.
- Psychoanalysis: A deep exploration of the person’s early experiences stored in the unconscious mind, revealed through talk therapy and dream analysis.
- Limitations: Tests of those theories don't always support their proposals.
Behaviorism
- A school of psychology that states that it’s not possible to accurately study the mind, studies behaviors instead.
- Founded by John B Watson.
- Learning can explain all behaviors.
- Believed that stimuli could produce specific responses.
- Pavlov's classical conditioning theory: A form of learning in which a neutral stimulus comes to elicit a response after being paired with a stimulus that naturally elicits that response.
- Skinner used the ideas of stimulus and response along with the application of rewards or reinforcement.
- Behaviorists agree with the nurture approach.
The Cognitive Approach
- A field of psychology that studies mental processes including perception, thinking, memory, and judgment.
- The cognitive approach was given more life because of our ability to see the brain in action using neuroimaging techniques.
- The processing causes the involved areas of the brain to increase blood flow.
- States that our brain is playing tricks on us; we have difficulty with contradicting stimuli.
- Cognitive Approach vs. Behaviorism: The cognitive approach provided a distinct alternative to behaviorism.
Socio-cultural Psychology
- The study of how social situations and cultures influence thinking and behavior.
- Conformity: Change of beliefs and behaviors to fit in.
- The most crucial part is social norms: The ways of thinking, feeling, or behaving being perceived as appropriate due to customs, traditions, and values.
Research Psychology
- Important because it helps us understand human behavior and mental processes.
- The scientific method: A step-by-step process used to explore questions, test ideas, and find answers.
Scientific Method Components
-
Theory: A well-supported idea that explains something based on evidence.
- Existing theories are modified on the basis of collected data.
- When a better theory is found, it replaces the old one.
-
Hypothesis: A specific, testable prediction about the relationship between two or more variables.
-
A good hypothesis should be:
- Testable: Tested through experiments or observations.
- Specific: Clearly defines the variables involved and their expected relationship.
- Falsifiable: Can be proven wrong, there must be evidence that contradicts it.
- Based on existing knowledge: Should be grounded in previous research or theories.
- Clear and concise: Stated in straightforward language.
-
A good hypothesis should be:
Types of Research Design
- Descriptive Research: Used to describe characteristics of a population.
- Correlational Research: Designed to discover relationships among variables.
- Experimental Research: A change of variable and a measurement of the effect of this change.
- Independent Variable (IV): Variable that is manipulated by the researcher.
- Dependent Variable (DV): Variable measured to assess the effect of the IV.
- Control Group: A group that doesn’t receive the experimental treatment used for comparison.
Research Ethics
- Research in psychology may cause stress, harm, or inconvenience for the people who participate in that research.
- Psychologists sometimes intentionally create lesions in animals to study the effects on their behavior.
Consciousness
- Refers to the state of being aware of and able to think and perceive one's own existence, thoughts, and environment.
- Awareness of surroundings.
- Attention to thoughts and feelings.
- The subjective experience of life.
Levels of Consciousness
- Full Consciousness: Being fully aware and engaged with the present moment and surroundings.
- Subconscious: Thoughts and memories that are not currently in the conscious mind but can be accessed.
- Unconscious: Concepts and feelings that are not accessible to awareness and can influence behavior.
Theories of Consciousness
- Biological perspective: Focuses on the brain’s role in consciousness, brain activity correlates with conscious experiences.
- Psychological perspective: Examines how consciousness relates to mental processes, including perception, thoughts, and emotions.
- Philosophical perspective: Explores the nature of consciousness, the “mind-body problem” and subjective experience.
Altered States of Consciousness
- Any mental state that differs from normal waking consciousness.
Sleep and Dreaming
-
Sleep: A natural, recurring state of rest characterized by altered consciousness, decreased sensory activity, and inhibition of bodily movements.
- Importance: Essential for physical health, cognitive function, emotional well-being, and overall quality of life.
- The patterns of sleep are recorded by monitors, such as an EEG.
Stages of Sleep
-
Non-REM Sleep:
- Stage 1: Light sleep; transition between wakefulness and sleep.
- Stage 2: Moderate sleep; heart rate slows, and body temperature decreases.
- Stage 3: Deep sleep; crucial for physical restoration and recovery.
-
REM Sleep:
- Characterized by rapid eye movement, increased brain activity, and vivid dreaming. Important for emotional regulation and memory consolidation.
-
Sleep Cycle:
- A full sleep cycle typically lasts about 90 minutes and includes multiple cycles throughout the night.
- Most deep sleep occurs in the first half of the night.
- REM sleep becomes longer in the second half of the night.
Stages of Sleep Breakdown
-
Stage 1 (N1) - Light Sleep
- Duration: Lasts for a few minutes (typically 1-7 minutes).
- Characteristics:
- Transition between wakefulness and sleep.
- Easily awakened; may not even realize they were asleep.
- Muscle activity slows, and the eyes move slowly.
- Brain waves begin to slow down from their daytime wakefulness patterns (alpha waves).
-
Stage 2 (N2) - Moderate Sleep
- Duration: Lasts about 10-25 minutes during the first cycle and increases with each cycle.
- Characteristics:
- Accounts for about 45-55% of total sleep in adults.
- No eye movement; heart rate, and body temperature decrease.
- Sleep spindles (brief bursts of brain activity) and K-complexes (sudden large waves) occur, which play a role in memory consolidation and protecting sleep from disturbances.
-
Stage 3 (N3) - Deep Sleep (Slow-Wave Sleep)
- Duration: Lasts about 20-40 minutes during the first cycle and typically decreases in duration with each subsequent cycle.
- Characteristics:
- Represents the deepest and most restorative sleep stage.
- Difficult to awaken; if awakened, individuals may feel groggy and disoriented (sleep inertia).
- Characterized by delta waves (slow brain waves) and minimal muscle activity.
- Essential for physical restoration, growth, and immune function; plays a vital role in repairing and rebuilding bodily tissues.
-
REM Sleep (Rapid Eye Movement)
- Duration: Lasts about 10-20 minutes in the initial cycle and increases with each subsequent cycle, making up about 20-25% of total sleep.
- Characteristics:
- Eyes move rapidly beneath closed eyelids; breathing becomes irregular.
- Brain activity is similar to wakefulness (beta waves), leading to vivid dreaming.
- The body experiences temporary muscle paralysis (atonia) to prevent acting out dreams.
- Important for emotional regulation, memory consolidation, learning, and creativity.
Sleep Disorders
-
Insomnia: Persistent difficulty falling or staying asleep.
- Insomnia can be caused by:
- Physical disorders.
- Psychological problems.
- Changes in sleep patterns.
- Insomnia can be caused by:
- Sleep apnea: A sleep disorder characterized by pauses in breathing that last at least 10 seconds during sleep.
-
Narcolepsy: A disorder characterized by extreme daytime sleepiness with frequent episodes of “nodding off.”
- Narcolepsy sufferers move directly into REM.
- Sleep paralysis: A phenomenon in which a person, either falling asleep or awakening, temporarily experiences an inability to move, speak, or react. It is often accompanied by terrifying hallucinations.
- Somnambulism (sleepwalking): In which the person leaves the bed and moves around while still asleep. Sleepwalking is more common in childhood.
- Sleep terrors: A disruptive sleep disorder, most frequently experienced in childhood, that may involve loud screams and intense panic. The sufferer cannot wake from sleep even though they’re trying to.
- REM sleep behavior disorder: A condition in which people engage in vigorous and bizarre physical activities during REM sleep in response to intense, violent dreams.
- Studies suggest that adults should get between 7 and 9 hours of sleep per night.
Dreams
- The succession of images, thoughts, sounds, and emotions that passes through our minds while sleeping.
- The content of dreams generally relates to everyday experiences and concerns, and frequently fears and failures.
Dream Theories
- We dream primarily to help with consolidation, or moving information into long-term memory.
- The activation-synthesis theory: Dreams are the brain’s interpretation of the random firing of neurons in the brain stem.
