EXPEPSY lesson 3 Flashcards
techniques that don’t manipulate antecedent conditions
NONEXPERIMENTAL STUDIES
events, circumstances, or actions that occur immediately before a behavior or event
Antecedent conditions
conditions that are needed prior to an experiment
Antecedent conditions
needed prior to the condition; alternatives; exp: randomization
Antecedent conditions
do not create levels of an independent variable nor randomly assign subjects to these levels
NONEXPERIMENTAL APPROACHES
used when experiments are not ethical or possible, or we want to test hypotheses in realistic conditions
NONEXPERIMENTAL APPROACHES
the degree to which a researcher can establish a causal relationship between the independent and dependent variables.
INTERNAL VALIDITY
_ has high internal validity if it can demonstrate that only the antecedent conditions are responsible for group differences in behavior
Experiment
only the required conditions
Antecedent conditions
_ experiment allows us to draw cause-and-effect conclusions
Internally Valid Experiment
often achieve higher internal validity than nonexperimental studies
Experiments
often higher in internal validity because they control extraneous variables
Laboratory experiments
Researchers create levels of the IV and use procedures like matching and random assignment to conditions
INTERNAL VALIDITY
Degree to which research findings can be generalized to other settings and individuals.
EXTERNAL VALIDITY
achieve higher external validity than laboratory experiments
Nonexperimental studies
More frequently conducted in real-world settings with a more diverse sample of participants than experiments
Nonexperimental studies
setting is controlled = internal validity is established
EXPERIMENT
Can be good at showing one thing causes another
INTERNAL VALIDITY
Might not represent what happens in the real world
EXTERNAL VALIDITY
increasing the internal validity
Randomization
research methods where the researchers do not intentionally change or manipulate the situations, events, or conditions being studied
NONEXPERIMENTAL STUDIES
Correlation and Description
Observation
No manipulation
Natural settings
NONEXPERIMENTAL STUDIES
degree of _ concerns the assignment of subjects to antecedent conditions created for the experiment
degree manipulation of antecedent conditions
How much do researchers intentionally change, alter or modify the things they’re studying
EX. tracking children’s regular diet to placing children on a strict diet
Degree of Manipulation of Antecedent Conditions
are usually high in the degree of manipulation
Experiments
usually low in the degree of manipulation
Nonexperiments
how much you limit a subject’s responses on the DV
Degree of imposition of units
How much control do researchers have over the participants or subjects involved (direct, influence, dictate) in the study.
Ex. household income, time spent on social media, number of siblings
Degree of imposition of units
Phenomenology
Case Studies
Field Studies
Archival Study
Qualitative Research
Nonexperimental Designs
involves a subject’s description of personal subjective experience
Phenomenology
low in manipulating antecedent conditions and low in the imposition of units (low-low)
Phenomenology
might rely on an experimenter’s private experiences or other experiential data:
Empirical phenomenology
The researcher’s self-reflection on relevant experiences.
Participants’ oral or written descriptions of their experiences.
Accounts from literature, poetry, visual art, television, theatre, and previous phenomenological (and other) research.
experiential data
The researcher’s self-reflection on relevant experiences.
experiential data
Participants’ oral or written descriptions of their experiences.
experiential data
Accounts from literature, poetry, visual art, television, theatre, and previous phenomenological (and other) research.
experiential data
a researcher compiles a descriptive study of a subject’s experiences, observable behaviors, and archival records kept by an outside observer
Case Studies
range from low-low to low-high
Case Studies
source of inferences, hypotheses, and theories
Case studies have several advantages:
source of therapy techniques allow study of rare phenomena
Case studies have several advantages:
provide exceptions to accepted ideas, theories, and practices
Case studies have several advantages:
persuasive and motivational value (advertising)
Case studies have several advantages:
Representativeness of sample (can be 1 participant)
Case studies have several limitations
Completeness of data
Case studies have several limitations
Reliance on retrospective data”
Case studies have several limitations
are recollections of past events that are collected in the present
Historical data or archival data, school records etc.
Retrospective Data
This information may be compromised by faulty memory, current mood, and the retrieval cues that are present when you are asked to recall an event.
Risks of using retrospective data
examines differences between deviant and normal individuals to identify etiological factors
Deviant Case Analysis
approach may also be applied to nonclinical issues such as social trends and adult morale
Deviant Case Analysis
are nonexperimental studies conducted in the field (real- life settings)
Field studies
range from low-low to low-high
Field studies
The experimenter does not manipulate antecedent conditions
Field studies
This method can achieve high levels of external validity because it’s conducted in a natural setting
Field studies
Naturalistic Observation
Participant-observer study
2 Types of Field Study
examines subjects’ spontaneous behavior in their actual environments and may obtain more representative behavior than experiments
Naturalistic observation
subjects alter their behavior when they know they are being observed
ex. PBB Bahay ni Kuya
Reactivity
way to collect or observe people without necessary observing them directly
unobtrusive methods
Involves field observation in which the researcher is part of the studied group
Participant-observer study
This approach contrasts with naturalistic observation, where the researcher does not interact with research subjects to avoid reactivity.
Participant-observer study
the invasion of privacy
not telling people that you are studying their behavior
pretending to be a group member.
Main problems of the Participant-observer study
is a serious problem that requires careful planning.
Pretending to be a group member
conducted in real-life settings; done in laboratory settings
Field experiments
Conducted in lab or controlled settings
Field experiments
nonexperimental designs
Field Studies
Used in real-life settings and include naturalistic observation, unobtrusive measures, participant-observer studies and surveys
Field Studies
Descriptive method where researchers reexamine data that were collected for other purposes
Archival Study
Obtains data consisting of words instead of numbers
QUALITATIVE RESEARCH
Information is obtained through self-reports, personal narratives and, expressing ideas, memories, feelings and thoughts
QUALITATIVE RESEARCH
Increased use of qualitative research may represent a paradigm shift
QUALITATIVE RESEARCH
a change in attitudes, values, beliefs, methods, and procedures accepted during a specific period
PARADIGM SHIFT
is invaluable in studying contextual phenomena and behavior that can only be understood within its context
QUALITATIVE RESEARCH
