Study Notes
Discovering Psychology
- The field of psychology focuses on understanding human behavior and mental processes through a systematic and scientific approach.
- Four primary goals of psychology are:
- Describe: Observing and documenting behaviors.
- Explain: Identifying the causes of behavior.
- Predict: Forecasting how individuals will behave in specific situations.
- Control: Influencing behavior in desired ways.
Modern Approaches
- Biological Approach: Investigates the interplay between genetics, hormones, the nervous system, and the environment. This interplay shapes various aspects of human behavior, including learning, personality, memory, motivation, emotions, and coping mechanisms.
- Cognitive Approach: Explores the processing, storage, and utilization of information, and how this information influences our perceptions and feelings. Cognitive neuroscience employs imaging techniques to identify the brain structures and functions involved in cognitive processes, such as thinking, planning, and object recognition.
Neurobiological Basis of Psychology
- Genes: Serve as the blueprints for development, containing chemical instructions that guide the formation of a complex body and brain. There are approximately 20,000 to 25,000 genes in the human body.
- Brain Development: The brain undergoes significant development during early stages, starting with three major divisions in the six-week-old brain and culminating in a mature brain with approximately 1 trillion cells and weighing almost 3 pounds.
Structure and Function of Neurons
- Neurons: Are the fundamental brain cells, each possessing two specialized extensions: one for receiving electrical signals (dendrite) and a longer extension for transmitting these signals (axon).
- Glial Cells: Support neurons by providing structural support, insulation, and chemical regulation. These cells play crucial roles in neural growth and function.
- Neuron Types and Function: There are various types of neurons, each responsible for specific functions, including sensory processing, motor control, and information processing.
Lobes of the Brain
- Frontal Lobe: Responsible for functions like planning, decision making, voluntary movement, and language production.
- Parietal Lobe: Processes sensory information related to touch, location of limbs, pain, and temperature.
- Temporal Lobe: Handles auditory information (hearing, recognizing sounds), language comprehension, and memory.
- Occipital Lobe: Processes visual information, including color perception, object recognition, and spatial awareness.
Limbic System
- Limbic System: A group of interconnected brain structures responsible for regulating motivation, emotions, and memory.
- Hypothalamus: Controls basic drives like hunger, thirst, and sexual behavior. It also influences emotional responses and hormone secretion.
- Adrenal Glands: Produce hormones that regulate sugar and salt balance, help cope with stress, and contribute to secondary sexual characteristics.
- Autonomic Nervous System: The hypothalamus regulates the autonomic nervous system, which controls involuntary bodily functions like heartbeat, breathing, and digestion.
Classical Conditioning
- Classical Conditioning: A learning process where a neutral stimulus acquires the ability to trigger a conditioned response due to its pairing with a specific stimulus that naturally elicits a response.
- Pavlov's Experiment: Demonstrated classical conditioning using dogs. He paired a neutral stimulus (bell) with an unconditioned stimulus (food) to elicit a conditioned response (salivation) after repeated pairings.
- Unconditioned Stimulus (UCS): A stimulus that naturally elicits a specific response. In Pavlov's experiment, food was the UCS.
- Unconditioned Response (UCR): The natural response elicited by the UCS without prior conditioning. In Pavlov's experiment, salivation was the UCR.
- Neutral Stimulus (NS): A stimulus that initially does not elicit the response of interest. In Pavlov's experiment, the bell was the NS.
- Conditioned Stimulus (CS): The previously neutral stimulus that now elicits a response after conditioning. In Pavlov's experiment, the bell became the CS after multiple pairings with the food.
- Conditioned Response (CR): The learned response to the previously neutral stimulus. In Pavlov's experiment, salivation to the bell became the CR.
