Study Notes
Psychology Professions
- Clinical Psychologists: Diagnose and treat mental illnesses; conduct psychological assessments.
- Social Workers: Provide mental health diagnosis and treatment.
- Psychiatrists: Medically treat mental health conditions with medications; focus on disorders like schizophrenia, bipolar disorder, depression, and anxiety.
- Industrial Psychologists: Specialize in hiring processes, employee feedback, and workplace structure for improved productivity.
- Forensic Psychologists: Collaborate with legal professionals, serve as expert witnesses, assess defendants for mental state in legal contexts.
Historical Figures in Psychology
- Wilhelm Wundt: Established the first psychology lab in 1879; focused on sensations and feelings; introduced introspection to understand conscious experience.
- Edward Titchener: A student of Wundt; developed structuralism, exploring the components of the mind and sensory experiences' basic elements.
- Charles Darwin: His theory of evolution influenced psychology; evolutionary psychologists consider how behaviors like attachment and emotions contribute to survival.
- Sigmund Freud: Neurologist who introduced concepts of the unconscious mind and defense mechanisms; highlighted the influence of unconscious processes on behavior and therapy.
Research Methods
- Hypothesis: A testable prediction about the relationship between variables; must be possible to disprove.
- Operationalization: Process of defining variable measures; essential for turning abstract concepts into quantifiable factors.
- Experimental Study: Involves manipulation of variables to establish causation; includes experimental and control groups; identifies independent and dependent variables.
- Correlational Study: Measures relationships between variables; important to note that correlation does not imply causation; can suffer from illusory correlation.
- Case Study: In-depth analysis of a single subject to gain detailed insights.
- Observational Study: Researchers observe subjects without interference to gather data over time.
- Survey: Collects data on beliefs or behaviors through structured questions; quality influenced by sample randomness and question phrasing.
- Confounding Variable: Extraneous factors that can skew study results; necessitates careful control in experiments.
Neurobiology
- Synapse: Junction between neurons for communication; neurotransmitters facilitate message transmission.
- Action Potential: Electrical impulse that travels down the axon, leading to neurotransmitter release at synapses; integral for neuron communication.
- Membrane Potential: Neurons at rest have a negative charge (-70 mV); ion channels regulate ion flow, maintaining this potential.
Neurotransmitters
- Serotonin: Associated with mood regulation and happiness; enhanced by exposure to light and physical exercise; SSRIs block serotonin reuptake to elevate mood.
- GABA: Main inhibitory neurotransmitter; alcohol can mimic GABA's calming effects; withdrawal from alcohol reduces GABA production, leading to stress and anxiety.
- Dopamine: Associated with pleasure and reward-seeking behavior.
- Endorphins: Act as natural painkillers and mood enhancers; opioids mimetically bind to their receptors, causing heightened euphoria and dependence.
Addiction Concepts
- Physical Dependence: Body's adaptation leading to increased tolerance and withdrawal symptoms upon cessation of drug use.
- Psychological Dependence: Emotional reliance on drugs to alleviate distressing feelings.
Brain Structure and Functions
- Brainstem: Manages vital involuntary functions like breathing and heart rate; considered the oldest brain structure.
- Cerebellum: Coordinates voluntary movement and balance; resembles a smaller brain.
- Cerebral Cortex: Responsible for higher-order functions such as sensory processing, cognition, and planning; divided into four lobes.
- Occipital Lobe: Processes visual stimuli including color and motion.
- Parietal Lobe: Integrates sensory information and spatial awareness; involved in proprioception.
- Temporal Lobe: Processes auditory signals, language, and memory.
- Frontal Lobe: Engages in executive functions: planning, problem solving, impulse control, and emotional regulation.
