Study Notes
Psychology Fundamentals
- Psychology is defined as the scientific study of behavior and mental processes.
- Founded as a discipline in 1879, marking its formal establishment.
- Wilhelm Wundt is recognized as the founder of psychology.
Historical Foundations
- Psychology emerged from two main fields: physiology and philosophy.
- Key early schools included structuralism, which utilized introspection, and functionalism, focusing on how mental processes help organisms adapt.
Major Psychological Perspectives
- Psychoanalysis, developed by Sigmund Freud, explores underlying motives and treat mental disorders.
- Biological Psychology examines connections between biology (genes) and behavior.
- Humanism emphasizes human interests and values, influenced by Carl Rogers and Abraham Maslow.
- Behaviorism, championed by John B. Watson and B.F. Skinner, focuses solely on observable behaviors without referencing mental processes.
- Cognitive Psychology studies mental processes like perception and memory.
- Evolutionary Psychology investigates behavior and mind evolution through natural selection.
Professional Specializations
- Clinical Psychologists address serious mental illness through testing, psychotherapy, and research.
- Counseling Psychologists help with general life problems.
- Psychiatrists are medical doctors with the ability to diagnose and treat mental disorders, including prescribing medication.
Research Themes and Methodology
- Seven key themes in psychology include empirical evidence, theoretical diversity, sociohistorical evolution, and the influence of culture and environment on behavior.
- Major goals of psychology comprise description, explanation, prediction, and control of behavior.
- Steps in the scientific method involve observation, background research, hypothesis formation, study design, data collection, analysis, and reporting of findings.
Understanding Behavior and Research
- A theory integrates principles to explain observations and predict behaviors.
- A hypothesis is a testable prediction based on a theory.
- Correlational studies explore relationships between variables, with positive correlation indicating moving in the same direction and negative correlation indicating opposite directions.
Neuroanatomy and Brain Function
- The human brain has four main lobes: frontal (thought processes), parietal (touch), temporal (auditory processing), and occipital (visual processing).
- Neurons, the basic units of the nervous system, include sensory, motor, and interneurons for communication.
- The central nervous system consists of the brain, spinal cord, and cerebrospinal fluid, while the peripheral nervous system encompasses all other nerves.
Neural Processes
- Myelin sheath insulates axons to increase signal transmission speed, with nodes of Ranvier providing gaps for conduction.
- Neurotransmitters like acetylcholine, serotonin, and dopamine facilitate communication between neurons, influencing various functions such as mood, movement, and arousal.
- Synaptic gaps are where neurotransmission occurs, with reuptake being the process of neurotransmitter reabsorption.
Nervous System Divisions
- The somatic nervous system controls voluntary muscle movements; the autonomic nervous system regulates involuntary actions.
- The endocrine system comprises glands like the adrenal and pituitary that secrete hormones influencing bodily functions.
Brain Structures and Functions
- The hindbrain includes the cerebellum (balance and coordination) and the medulla (breathing and heart rate).
- The midbrain integrates sensory processes, with significant structures such as the superior and inferior colliculus.
- The forebrain, the largest brain region, houses important structures like the thalamus (sensory relay), hypothalamus (homeostasis), limbic system (emotion and memory), and cerebrum (higher functions).
Sensation and Perception
- Sensation involves the stimulation of sense organs, while perception is the interpretation and organization of sensory input.
- Signal detection theory explains how and when we detect faint stimuli amidst background noise, influenced by expectations and experience.
Vision and Eye Anatomy
- The eye's pupil adjusts to control light entry, while the iris regulates pupil size.
- The cornea is the eye's outer transparent layer, with rods and cones located in the retina's periphery and center, respectively, for low-light sensitivity and color vision.
