Pysch Mid-term Exam Flashcards
Philosophers
Plato, Socrates, Aristotle
Functionalism
focused on the functions and purposes of the mind and behavior - William James
Structuralism
Wilhelm Wundt - aimed to analyze the structure of the mind through introspection
Wilhelm Wundt
considered the father of psychology, established the first psych lab and is associated with structuralism
Descartes and Locke
Descartes - proposed mind-body dualism, Locke’s ideas contributed to empiricism and the concept of tabula rasa (“blank slate”)
Biopsychosocial Approach
An integrated perspective emphasizing the biological, psychological, and social factors influencing behavior and mental processes
7 Perspectives
Biological, Cognitive, Behavioral, Humanistic, Psychodynamic, Evolutionary, and Sociocultural
Circadian Rhythm
the internal body clock regulating the sleep-wake cycle over roughly 24 hours
Sleep Cycle
the recurring patterns of sleep stages, including REM (rapid eye movement) and NREM (non rapid eye movement) sleep
REM Sleep
a sleep stage characterized by rapid eye movements, vivid dreams, and heightened brain activity
NREM Sleep Stages 1-4
Different stages of non-REM sleep, each with distinct brain wave patterns and characterisitcs
Amphetamines, Barbiturates, Opiates
types of drugs affecting the central nervous system with varying effects on mood, perception, and consciousness
Stimulants, Depressants, Hallucinogens
types of drugs with distinct effects on the nervous system and behavior
Manifest Content vs. Latent Content
Freud Theory: manifest content refers to the apparent storyline of a dream - latent content represents its underlying, often symbolic, meaning
Scientific Method
a systematic approach to inquiry involving observation, hypothesis formation, experimentation, data analysis, and conclusion drawing
Parts of the Scientific Method
Observation, Question, Hypothesis, Prediction, Experimentation, Analysis, Conclusion
Independent Variable
the variable manipulated or controlled by the researcher in an experiment
Dependent Variable
the variable being measured or observed; its changes are influenced by the independent variable
Experimental Condition
The group in an experiment exposed to the independent variable
Control Condition
The group is an experiment that is not exposed to the independent variable; used as comparison to assess the impact of the independent variable
Overconfidence
The tendency to be overly confident in one’s beliefs or judgements
Hindsight Bias
the tendency to believe, after learning an outcome, that one would have foreseen it
Correlation
a statistical measure indicating the extent of the relationship between two variables
Correlation Coefficient
a number between -1 and +1 that represents the strength and directions of the relationship between variables
Standard Deviation
A measure of the amount of variation or dispersion in a set of data
Naturalistic Observation
A research method involving the observation of subjects in their natural environment without any manipulation
Survey-Wording Effect
The impact of subtle changes in wording or phrasing of survey questions on respondents’ answers
Case Study
an in-depth analysis of a single individual or a small group over an extended period to gain insights into a particular phenomenon
Double-Blind Procedure
An experimental technique where both the participants and the researchers interacting with them are unaware of the treatment or condition to eliminate bias
Placebo Effect
a phenomenon where a participant’s expectation or belief in a treatment’s effectiveness causes them to experience improvement, even if they’ve received a placebo or inert substance
Biological Psychology
The branch of psych that focuses on the relationship between behavior and physiological processes
Parts of a Neuron
Neurons are comprised of the cell body, dendrites, and axons
Threshold
the level of stimulation needed to trigger a neural impulse or action potential
Synapse
the junction between two neurons where communication occurs via neurotransmitters
Neurotransmitters
chemical messengers that transmit signals across synapses
Acetylcholine, Dopamine, Serotonin
neurotransmitters associated with various functions like movement, mood regulation, and pleasure
Endorphins
neurotransmitters acting as natural painkillers or mood elevators
Nervous System
the body’s communication network, consisting of the central nervous system (brain and spinal cord) and peripheral nervous system (nerves and ganglia)
Automatic Nervous System
controls involuntary functions; the parasympathetic division conserves energy, while the sympathetic division mobilizes energy
Endocrine System
the system of glands that secrete hormones directly into the bloodstream to regulate various bodily functions
Pituitary Gland
often term the “master gland,” it controls the release of hormones from other glands and regulates growth
Lesions
areas of damage or abnormal tissue in the body, often studied to understand specific functions
Different Scans
EEG, PET, MRI, fMRI - all used to study brain structure and activity
Brain Regions
Brainstem, Medulla, Thalamus, Cerebellum, Amygdala, Hypothalamus, Cerebral Cortex, Four Lobes (Frontal, Parietal, Temporal, Occipital)
Motor Cortex vs. Sensory Cortex
areas of the cerebral cortex responsible for motor functions and sensory processing
Plasticity
The brains ability to reorganize itself by forming new neural connections throughout life
Corpus Callosum
a structure connecting the two hemispheres of the brain, facilitating communication
Aphasia
language impairment typically resulting from brain damage
Secure Attachment vs. Insecure Attachment
refers to the bond between and child and caregiver; secure attachment involves trust and comfort, while insecure attachment may manifest as avoidance or anxiety
