    Study Notes

    Psychology Perspectives

    • Biological Perspective focuses on how brain chemistry influences behavior.
    • Cognitive Perspective focuses on how we think and reason.
    • Sociocultural Perspective focuses on external factors influencing behavior.

    Brain and Nervous System

    • The brain consumes around 25% of the body's oxygen.
    • The brain has an estimated 100 billion nerve cells (neurons).
    • Frontal Lobe: Contains the motor cortex.
    • Parietal Lobe: Contains the somatosensory cortex.
    • Hypothalamus: Associated with sex.
    • Hippocampus: Associated with memory.
    • Dopamine is a neurotransmitter associated with Parkinson's disease.

    Research Methods

    • Double-Blind Procedure: Neither the experimenter nor participants know which treatment is being administered.
    • Case Studies: In-depth investigations of a specific case or situation.
    • Naturalistic Observation: Observing behavior in its natural setting without intervention.
    • Participatory Observation: Observers actively engage with the group being studied.
    • Experimental Techniques: Used to determine cause-and-effect relationships.
    • Correlational Techniques: Used to predict events.

    Neurotransmitters

    • Agonists: Increase the activity of neurotransmitters.
    • Antagonists: Decrease the activity of neurotransmitters.
    • Acetylcholine (ACh): Agonistic to Black Widow spider venom.
    • Gamma-Aminobutyric Acid (GABA): Agonistic to antianxiety drugs.

    Imaging Techniques

    • fMRI (functional magnetic resonance imaging): Less invasive, produces sharper images than PET scans.

    Learning and Conditioning

    • Classical Conditioning is also known as Pavlovian conditioning.
    • Unconditioned Stimulus (UCS): Automatically triggers an unconditioned response (UCR).
    • Unconditioned Response (UCR): An automatic response to an unconditioned stimulus.
    • Conditioned Stimulus (CS): Previously neutral stimulus that becomes associated with an unconditioned stimulus.
    • Conditioned Response (CR): Learned response to a conditioned stimulus.
    • Generalization: Responding similarly to stimuli similar to the conditioned stimulus.
    • Extinction: Gradual disappearance of a conditioned response.
    • Spontaneous Recovery: Reappearance of a conditioned response after extinction.

    Reinforcement and Punishment

    • Positive Reinforcement: Increases behavior by adding a positive stimulus.
    • Negative Reinforcement: Increases behavior by removing an aversive stimulus.
    • Positive Punishment: Decreases behavior by adding an aversive stimulus.
    • Negative Punishment: Decreases behavior by removing a positive stimulus.
    • Fixed-Ratio Schedule of Reinforcement: Reinforcement is delivered after a fixed number of responses.
    • Primary Reinforcers: Inherently rewarding (food, water).
    • Secondary Reinforcers: Learned to be rewarding (money, praise).

    Theories of Motivation

    • Arousal Theory: Motivation is related to maintaining an optimal level of arousal.
    • Yerkes-Dodson Law: Performance increases with arousal up to a certain point, then decreases with further increases in arousal.

    Observational Learning

    • Modeling: Learning by observing and imitating others.
    • Albert Bandura: Famous for his Bobo doll experiment, demonstrating observational learning.
    • Instinctual Drift: Tendency for learned behaviors to revert to instinctive behaviors.

    Social Psychology

    • Media violence increases the likelihood of aggressive behavior, especially in children and adolescents.

    Important Terms

    • Neuron: Nerve cell.
    • Axon: Long, singular fiber extending from the cell body of a neuron.
    • Reflex: Automatic, involuntary response to a stimulus.
    • Latent Learning: Learning that occurs without immediate reinforcement and is not apparent until there is a need to use it.

    Psychology Perspectives

    • Biological Perspective: Focuses on how brain chemistry influences behavior.
    • Sociocultural Perspective: Explains behavior based on external factors like social norms and cultural influences.
    • Cognitive Perspective: Studies how we think and reason.

    Brain Anatomy and Function

    • Frontal Lobe: Associated with motor cortex, voluntary movement, and higher-order thinking.
    • Parietal Lobe: Houses the somatosensory cortex, which processes sensory information like touch and temperature.
    • Hypothalamus: Regulates basic drives like hunger, thirst, and sex.
    • Hippocampus: Plays a crucial role in memory formation.

    Neurotransmitters

    • Dopamine: Low levels are linked to Parkinson's disease.
    • Acetylcholine (ACh): Black widow spider venom acts as an agonist to ACh.
    • GABA: Antianxiety drugs act as agonists to GABA.

    Research Methods

    • Case Study: An in-depth study of a single individual or group to understand a phenomenon.
    • Naturalistic Observation: Observing behavior in its natural setting without manipulation.
    • Participatory Observation: The observer becomes part of the group they are studying.
    • Experimental Research: Used to establish cause-and-effect relationships.
    • Correlational Research: Used to predict events, but doesn't prove causation.

    Brain Imaging Techniques

    • fMRI (functional magnetic resonance imaging): Provides sharper images and is less invasive than PET scans.
    • PET (positron emission tomography): Less common due to higher cost and procedural requirements.

    Communication Within and Between Neurons

    • Within neurons: Communication is electrical.
    • Between neurons: Communication is chemical, using neurotransmitters.

    Learning Theories

    • Classical Conditioning (Pavlovian Conditioning): Learning through association of stimuli.
    • Operant Conditioning: Learning based on consequences of behavior.
    • Latent Learning: Learning that occurs without immediate reinforcement but is demonstrated later.
    • Observational Learning (Modeling): Learning by watching and imitating others.
    • Instinctual Drift: The tendency for learned behavior to revert to instinctive behaviors.

    Reinforcement and Punishment

    • Positive Reinforcement: Increases behavior by adding a desirable stimulus.
    • Negative Reinforcement: Increases behavior by removing an aversive stimulus.
    • Positive Punishment: Decreases behavior by adding an aversive stimulus.
    • Negative Punishment: Decreases behavior by removing a desirable stimulus.

    Types of Reinforcers

    • Primary Reinforcers: Basic biological needs like food and water.
    • Secondary Reinforcers: Learned reinforcers through association with primary reinforcers (e.g., money, praise).

    Schedules of Reinforcement

    • Fixed-Ratio: Reinforcement after a specific number of responses (e.g., commission for every 10 boxes sold).

    Generalization and Discrimination in Conditioning

    • Generalization: Responding similarly to stimuli that are similar to the conditioned stimulus.
    • Discrimination: Responding differently to stimuli that are different from the conditioned stimulus.

    Media Violence and Aggression

    • Research suggests that exposure to media violence increases the likelihood of aggressive behavior.

    Yerkes-Dodson Law

    • Relates to the arousal theory of motivation: optimal performance occurs at moderate levels of arousal.
