Comprehensive Psychology Study Guide: Research Methods, Clinical Assessment, and Psychopathology

Comprehensive vocabulary flashcards covering key concepts from research methods, clinical assessment, diagnosis, multidimensional etiology, and treatment modalities in psychopathology.

Independent Variable

The variable in an experiment that is manipulated by the researcher to observe if it affects another variable, acting as the cause in a cause-and-effect relationship.

Dependent Variable

The variable in an experiment that is expected to change in response to the manipulation of the independent variable, representing the effect in a cause-and-effect relationship.

Experimental Group

The group of participants in research that receives the treatment or intervention being tested.

Control Group

The group of participants in research who do not receive the treatment or intervention, serving as a baseline to isolate the effect of the independent variable.

Random Assignment

The procedure of placing participants into experimental or control groups by chance to ensure groups are comparable on average prior to variable manipulation, reducing bias.

Observational Studies

A descriptive research method that involves systematically observing and recording behavior in natural settings without variable manipulation.

Case Studies

In-depth examinations of a single individual, group, or event, often focusing on unique or unusual cases.

Quantitative Data

Numerical and measurable data, such as test scores, sales figures, age, and income, that can be analyzed using statistical tools.

Qualitative Data

Descriptive and non-numerical data—such as words, images, observations, and open-ended responses—focused on subjective understanding and contextual meaning.

Correlational Research

A research design in psychology that examines the relationships between two or more variables to determine if they are associated, without manipulating or controlling them.

Correlation Coefficient

A statistic ranging from $-1.00$ to $+1.00$ that quantifies the strength and direction of a linear relationship between two variables.

Clinical Assessment

A systematic evaluation and measurement of psychological, biological, and social factors in an individual presenting with a possible psychological disorder.

Reliability

The degree to which a measurement instrument consistently yields dependable outcomes when repeated under the same conditions.

Validity

The extent to which an assessment tool or experiment measures exactly what it is designed to measure.

Standardization

The application of consistent standards across administration, scoring, and evaluation procedures to ensure comparability across measurements and provide population benchmarks.

Mental Status Examination (MSE)

A structured assessment tool used by clinicians to observe and evaluate a patient's current mental functioning across domains such as appearance, mood, thought process, and cognition.

ABCs of Observation

A framework in behavioral assessment focused on identifying Antecedents (what happens prior to behavior), Behaviors, and Consequences (what happens after).

Projective Tests

Unstructured psychological assessment tools rooted in psychoanalytic tradition where individuals project aspects of their personality onto ambiguous stimuli.

Objective Tests

Psychological tests using direct, unambiguous stimuli with structured response options requiring minimal clinical inference, such as the MMPI.

Deviation IQ

An intelligence score determined by comparing an individual's performance to same-age peers, historically calculated as $\text{Mental Age} / \text{Physical Age} \times 100$.

Neuropsychological Testing

Assessment methods (such as Luria-Nebraska and Halstead-Reitan batteries) designed to evaluate cognitive skills, brain health, and brain-behavior relationships.

DSM-5-TR

The Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition, Text Revision, published in $2022$ to provide updated diagnostic criteria and codes for mental health disorders.

Epigenetics

The study of how environmental and social influences alter gene activity and expression without changing the underlying DNA sequence.

Biopsychosocial Model

A holistic framework that attributes psychopathology to the complex interaction of biological, psychological, and social or cultural factors.

Diathesis-Stress Model

A theory proposing that a psychological disorder develops when an underlying biological or genetic vulnerability (diathesis) combined with environmental stress exceeds an individual's threshold.

Polygenic Inheritance

A genetic principle stating that multiple genes interact together to contribute to the development of complex traits and mental disorders.

Heritability

A statistical estimate measuring the proportion of phenotypic trait variation within a population that is attributable to genetic differences among individuals.

Serotonin

A key neurotransmitter and neuromodulator that regulates mood, sleep, appetite, digestion, pain, and emotional stability.

Dopamine

A neurotransmitter involved in movement, memory, motivation, focus, and the brain's reward and pleasure systems.

GABA

The primary inhibitory neurotransmitter in the central nervous system that slows down overactive neural firing to promote relaxation and calm.

Somatic Nervous System

The subdivision of the peripheral nervous system responsible for transmitting sensory and motor signals to execute voluntary muscle movements.

Autonomic Nervous System

The subdivision of the peripheral nervous system that regulates involuntary bodily functions, including heart rate, respiration, and digestion.

Sympathetic Nervous System

The branch of the autonomic nervous system that mobilizes bodily energy to prepare an organism for emergencies or threats via the fight-or-flight response.

Parasympathetic Nervous System

The branch of the autonomic nervous system associated with energy conservation and normal body maintenance during relaxed conditions.

Frontal Lobe

The forward brain structure involved in reasoning, planning, creativity, motor control, emotion, language production (Broca's area), and executive functions.

Agonist

A psychotropic chemical that binds to a neurotransmitter receptor site and mimics or strengthens the effects of that neurotransmitter.

Antagonist

A psychotropic drug that blocks or impedes the normal biological activity of a neurotransmitter at its postsynaptic receptor site.

Freud's Unconscious

The vast portion of the mind containing mental activity, emotional drives, and motivations of which an individual is unaware and unable to access consciously.

Id

The primitive, unconscious component of personality present at birth that operates on instinctual drives for hunger, thirst, aggression, and sex.

Superego

The component of personality that develops through social interaction to embody moral standards, conscience, and rules for right and wrong.

The rational part of personality that seeks to satisfy id impulses in realistic ways while mediating conflicts with the superego.

Denial

A psychoanalytic defense mechanism characterized by refusing to acknowledge or accept unpleasant real-world events or facts.

Displacement

A defense mechanism involving the transfer of inappropriate or aggressive urges onto a safer, less threatening target.

Projection

A defense mechanism where an individual attributes their own unacceptable desires, thoughts, or motives onto other people.

Rationalization

A defense mechanism in which an individual justifies unacceptable behaviors by substituting plausible, acceptable reasons for the true motives.

Reaction Formation

A defense mechanism where a person reduces anxiety by expressing beliefs and behaviors that are directly opposite to their true underlying feelings.

Regression

A defense mechanism in which an individual reverts to coping strategies and behaviors characteristic of an earlier developmental stage.

Repression

A defense mechanism involving the involuntary suppression and exclusion of painful thoughts and traumatic memories from conscious awareness.

Sublimation

A defense mechanism where unacceptable instinctual desires or aggressive drives are redirected into constructive, socially acceptable activities.

Free Association

A core psychoanalytic treatment method where the client speaks aloud whatever thoughts come to mind without censoring or organizing them.
