Exam 1 (Ch.1,3,4) Flashcards
Behavioral Perspective
an approach that focuses on external, environmental influences on behavior
Behaviorism
a psychological perspective that emphasizes the study of observable stimuli, responses, and consequences
Biological Perspective
an approach that focuses on physical causes of behavior
Case study
an in-depth observation of one or a few participants or settings
Casual hypothesis
an educated guess about how one variable will influence another variable
Cognition
mental processes such as reasoning and problem solving
Cognitive Perspective
an approach that focuses on how mental processes influence behavior
Confidentiality
the ethical principle that researchers do not reveal which data were collected from which participant
Confirmation Bias
a tendency to interpret people’s behavior in a way that supports our expectations
Cofounding Variables
factors other than the independent variable that affect the dependent measure
Control Group
the group of participants who do not receive the manipulation that is being tested
Correlation
the relationship between two or more variables
Critical Thinking
thought processes used to evaluate and analyze information and apply it to other situations
Debriefing
the ethical principle that participants be fully informed of the nature of the study after participating in research involving deception
Dependent Variable
the variable in an experiment that measures any effect of the manipulation
Double-Blind Studies
experiments in which neither the experimenters nor the participants know to which group (experimental or control) participants have been assigned
Eclectic approach
an approach that integrates and combines several perspectives when explaining behavior
Evolutionary perspective
an approach that focuses on how evolution and natural selection influence behavior
Experiment
a research method that is used to test causal hypotheses
Experimental Group
the group of participants who receive the manipulation that is being tested
Functionalism
an early psychological perspective concerned with how behavior helps people adapt to their environment
Generalizability
how well a researcher’s findings apply to other individuals and situations
Humanism
a psychological perspective that emphasizes the personal growth and potential of humans
Humanistic Perspective
an approach that focuses on how peoples’ view of themselves and the world influence behavior
Hypothesis
Educated guess
Independent variable
the variable in an experiment that is manipulated
Informed Consent
the ethical principle that research participants be told about various aspects of the study, including any risks, before agreeing to participate
Institutional Review Board (IRB)
a committee that reviews research proposals to ensure that ethical standards have been met
Introspection
observing one’s own thoughts, feelings, or sensations
Meta-analyses
research procedures that combine the findings from a number of scientific studies on the same question or topic to establish the reliability of the findings, observe any overall trends, and to resolve any discrepancies among the research studies
Naturalistic Observations
research studies conducted in an environment in which the behavior typically occurs
Negative Correlation
a relationship in which increases in one variable correspond to decreases in the other variable
Neuroscience
a field of science that investigates the relationships between the nervous system and behavior/mental processes
Placebo Effect
a measurable change in participants’ behavior due to the expectation or belief that a treatment will have certain effects
Population of Interest
the entire universe of animals or people that could be studied
Positive Correlation
a relationship in which increases in one variable correspond to increases in the other variable
Positive Psychology
the study of factors that contribute to happiness, positive emotions, and well-being
Prediction
an expected outcome of how variables will relate
Predictive Hypothesis
an educated guess about the relationships among variables
Pseudo-psychology
psychological information or conclusions that sound scientific but have not been systematically tested using the scientific method
Psychoanalytic Theory
Sigmund Freud’s view that emphasizes the influence of unconscious desires and conflicts on behavior
Psychodynamic Perspective
an approach that focuses on internal unconscious mental processes, motives, and desires that may explain behavior
Psychology
the scientific study of behavior and mental processes
Quasi-experiment
a research study that is not a true experiment because participants are not randomly assigned to the different conditions
Random Assignment
a method of assigning participants in which they have an equal chance of being placed in any group or condition of the study
Response
an organism’s reaction to a stimulus
Sample
the portion of the population of interest that is selected for a study
Scientific Method
a systematic process used by psychologists for testing hypotheses about behavior
Sociocultural Perspective
an approach that focuses on societal and cultural factors that may influence behavior
Stimulus
any object or event that is perceived by our senses
Structuralism
an early psychological perspective concerned with identifying the basic elements of experience
Surveys
research methods that ask a large group of people about their attitudes, beliefs, and/or behaviors
Theory
an explanation of why and how a behavior occurs
Absolute Threshold
the minimum intensity of a stimulus at which participants can identify its presence 50% of the time
Accommodation
the process through which the lens is stretched or squeezed to focus light on the retina
Amplitude
a physical property of some energies that corresponds to the height of wave peaks
Attention
conscious awareness; can be focused on events that are taking place in the environment or inside our minds
Auditory Nerve
the nerve that carries information from the inner ear to the brain
Basilar Membrane
the structure in the cochlear duct that contains the hair cells, which convert sound waves into neural impulses
Binocular Depth Cues
depth cues that utilize information from both eyes
Blindspot
the point where the optic nerve leaves the retina (the optic disk), where there are no rods or cones
Bottom-up processing
perception that is not guided by prior knowledge or expectations
Brightness
the intensity of light; it corresponds to the amplitude of the light waves
Closure
a Gestalt principle of perception that states that when we look at a stimulus, we tend to see it as a closed shape rather than lines
Cochlea
the curled, fluid-filled tube in the inner ear that contains the basilar membrane
