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.
