Research Methods
THE SCIENTIFIC METHOD
Gain knowledge about human and animal behavior. It is an abstract concept, and an investigative approach to knowledge, distinguished from "general" (everyday) knowledge
RECORDING BEHAVIOR
What should be recorded? Optimal ideas, concepts, theory, and hypotheses determine what should be recorded.
spurious
When a relationship between two variables can be explained by a third variable
· Minimal Risk =
When a research study involves procedures or activities that are similar to those experienced by participants in their everyday life, the study is described as having "minimal risk." Your research projects will involve minimal risk (only).
· A HYPOTHESIS
a statement or question that functions as a tentative explanation for a phenomenon
A hypothesis
a tentative explanation for a phenomenon; testable hypotheses have clearly defined concepts (operational definitions), are not circular, and refer to concepts that can be observed.
nonprobability sampling techniques
accidental sampling and purposive sampling, there is no guarantee that every element in the population has an equal chance of being included in the sample.
· Scientific instruments
accurate and precise; physical and psychological measurement should be valid and reliable.
indirect observations
archival information, examination of evidence
· Operational Definitions
are crucial in conducting any research. Concepts are things and/or events loosely discussed in terms of their relationships to one another. Operational definitions explain the concepts in terms of the specific operations they will perform or portray (utility).
Dependent variables
are measures of behavior used to assess the effects of independent variables
the news media popular press
include a wealth of variables associated with what is "found" in the media.
running records
include data that are generally updated on a regular or semi-regular basis
measures of effect size
indicate the strength of the relationship between the independent and dependent variables, but are not affected by sample size.
Construct validity
represents the extent to which a measure assesses the theoretical construct it is designed to assess; construct validity is determined by assessing convergent validity and discriminant validity
TheF-test is a statistic that
represents the ratio of between-group variation to within-group variation in the data. (Parallel with the t-test.)
Field Experiments
researchers manipulate one or more independent variables in a natural setting to determine the effect on behavior.
High interobserver reliability increases
researchers' confidence that observations about behavior are valid - that they have MEANING, and are related to the hypothetical goals and theory
· Description =
the procedures by which relationships are defined, cataloged, classified, and categorized (some would say operationalized)
· Selection bias occurs when
the procedures used to select a sample result in the overrepresentation or underrepresentation of some segment(s) of the population.
Observational data are summarized through
the process of data reduction
Physical Traces
walking speed (direct observation) is highly correlated with the accuracy of a country's clocks (unobtrusive measure - examination of physical evidence). The more accurate the clocks, the faster people generally walk!
· General versus Empirical Approaches:
we normally use general and every day cognitive processes to investigate and deal with knowledge. This is the intuitive approach, perfectly acceptable, and very adaptive (the feeling that...). The Empirical emphasizes acquiring knowledge through direct observation and experimentation.
Expectancy effects can occur
when observers are aware of hypotheses for the outcome of the study or the outcome of previous studies.
· Internal Validity =
when the "controllable" confounds are identified and dealt with, when the study or assessment is functioning at a "truth" level in relation to the hypothesis (es)
· Confounding =
when two or more potentially effective (measurable) variables covary and no separation is made
3 Steps for a Content Analysis:
· 1. Identify archival data source 2. Sample data from the records 3. Code contents of the records
RESEARCH WITH ANIMALS
· Animals are used in research to gain knowledge that will benefit humans, for example, by helping to cure diseases. cost/benefit ratio
Rationale - Archival data
· Test hypotheses as part of multivariate research approaches (and often are) · · To establish external validity of experimental (especially lab) experiments and studies (compare results) · · Assess the effects of natural treatments (home field advantage, treatment outcome assessed by a review of re-admission/relapse figures). .Archival data are often used (and mis-used) in all social sciences (especially demography, political science, and sociology).
· What is Methodology 3 parts
· What is Methodology
Path analysis
· statistical technique used to help researchers understand potential causes of correlational relationships.
Mediators
· variables that help to explain the relationship between two variables-
Observation without intervention
The goals of naturalistic observation are to describe behavior as it normally occurs and to examine relationships among variables. There is no manipulation or intervention.
· Are the correlations significant?
The magnitude of a correlation coefficient ranges from -1.0 (a perfect negative relationship) to +1.0 (a perfect positive relationship); a correlation coefficient of 0.00 indicates no relationship.
Assessing effects of natural treatments
(car accidents, injuries, and enactment of seatbelt laws)
Placebo control groups are used to control for
the problem of demand characteristics, and double-blind experiments control both demand characteristics and experimenter effects.
what is Logic
(deductive {general-to-specific/theory-to-data}, inductive {specific-to-general/data-to-theory}, mixed, active, passive, reciprocal)
Analysis of Trend
(female representation in the workforce, students admitted to graduate programs)
Analysis of communication
(language use changes, fake versus real threats and suicide notes, presidential candidates and various audiences)
what is Epistemology
(relationship between knower and what is known; subjective versus objective {dualism})
what is Axiology
(relationship of values to the knower, what is known, and the nature of the inquiry)
whats ontology
(the realism versus relativism debate - Is reality global, or unique to each individual?)
· Instruments and Measurement
What "tools" are being used and how are measurements being made (operationally) are also vital to the scientific method.
STEPS FOR ETHICAL DECISION MAKING
1. Get the facts. What is involved regarding procedure, participants, methodology, etc. (incl. cost/benefit ratio related to research design.)? 2. Identify the important and related ethical issues. Consult the APA and other guidelines (incl. testing bias and fairness issues), groups and organizations, and be aware of state, local, and federal regulations (do not simply rely on word-of-mouth). 3. Formally analyze the cost/benefit ratio related to all parties. What is the overall gain compared to the overall loss? Is anyone being hurt and is it worth it compared with those who may be benefiting. 4. Be aware of alternative procedure and methodology (incl. protocol). Normally, there is at least one alternative methodology available. 5. Decide on the final steps to take. Have all of the questions been asked? Have all of the alternatives been explored?
OBSERVATION WITH INTERVENTION 3 methods
1. participant observation 2. structured observation 3. the field experiment
· An experiment has internal validity when it fulfills the three conditions required for causal inference:
1.Covariation 2. Time-order relationship 3. Elimination of plausible causes
What is variability
A measure of dispersion around the mean, equal to the sum of squared deviations from the mean divided by one less than the number of cases. The variance is measured in units that are the square of those of the variable itself
what is standard deviation
A measure of dispersion around the mean.
· THE RISK/BENEFIT RATIO =
A subjective evaluation of the risks and benefits of a research project is used to determine whether the research should be conducted. The RESEARCHER makes the subjective evaluation. The IRB "weighs" the argument - then makes their decision.

CONSISTENCY AMONG RATERS:
Interobserver reliability refers to the extent to which independent observers agree in their observations.
· IV
Is that which is controlled or manipulated
DV
Is that which is measured. Asking dependent upon what is a trick
· What are 6 Issues in Scientific Inquiry:
Methodology, logic, epistemology, axiology, ontology, cause and effect laws
· Determination of Risk =
Potential risks in psychological research include risk of physical injury, social injury, and mental or emotional stress. Risks must be evaluated in terms of potential participants' everyday activities, their physical and mental health, and capabilities. Do the benefits OUTWEIGH ALL of the risks?
· Reliability and Validity:
Properties that measurements, instruments, definitions, results, etc. MUST have in order to carry any logical, implied, and "meaningful" weight
· SCIENTIFIC INTEGRITY -
Psychologists are obligated to conduct research of the highest integrity.
what is r squared
R-squared is the effect size, it represents the strength of the relationships between variables. It is used to express the correlation between variables and whether the correlation is significant. The r- squared is the coefficient of determination, value of the multiple correlation coefficient
Random Assignment
Random assignment to conditions is used to form comparable groups by balancing or averaging subject characteristics across the conditions of the independent variable manipulation.
· Obtaining Informed Consent =
Researchers and participants enter into a social contract, often using an informed consent procedure. Researchers are ethically obligated to describe the research procedures clearly, identify any potential risks that might influence individuals' willingness to participate, and answer any questions participants have about the research.
· Deception=
Researchers must carefully weigh the costs of deception against the potential benefits of the research when considering the use of deception. See risk/benefit ratio.
Situation Sampling
Situation sampling involves studying behavior in different circumstances, locations, and conditions and often with different participants example: assess the aggressive behavior of first grade boys in a variety of settings - school, home, stores, bus, etc
· Goals of the Scientific Method
The scientific method is intended to meet three goals: description, prediction, and understanding/creating change.
Participant Observation
Undisguised participant observation is often used to understand the culture and behavior of groups of individuals. Participants KNOW they are being observed Disguised participant observation is often used when researchers believe individuals would change their behavior if they knew it was being recorded.
· Dealing with Risk =
Whether "at risk" or "at minimal risk," research participants must be protected. More safeguards are needed as risks become greater.
an experiment has external validity when...
[ When findings from an experiment can be applied to other individuals, settings, and conditions
Interobserver reliability is assessed by
calculating percentage 8 agreement or correlations, depending on how the behaviors were measured and recorded.
Nominal
categories (brown/blue eyed; women/men
An ethogram is a....
complete catalog of behavior (Grooming behavior in chimps, rearing behavior in mice).
the groups (known as factors) of data involved in observational data
components, dimensions, clusters, and latent or composite variables (in some cases).
· Reliability
consistency
A matched group design may be used to
create comparable groups when there are too few subjects available for random assignment to work effectively. Often used with "specialized" participants (infants, the elderly, athletes, etc.).
analysis of variance can be used to
decide whether an independent variable has had a statistically significant effect, researchers examine the descriptive statistics to interpret the meaning of the experiment outcome.
· Prediction =
description of a relationship, usually directional
Analysis of variance (ANOVA) is an inferential statistics test used to
determine whether an independent variable has had a statistically significant effect on a dependent variable. (Does giving one group various levels of strategy and another group no strategy result in differences in the number of words recalled?)
Null-hypothesis testing is used to
determine whether mean differences among groups in an experiment are greater than the differences that are expected simply because of error variation
Naturalistic observation helps to...
establish the external validity of research findings by verifying relationships found in the lab in naturalistic settings.
Narrative (written, spoken) records
form of written descriptions of behavior, audiotapes, and videotapes are comprehensive records of observed behavior. The goal is to study, organize, and/or classify records depending on need (and context).
· External Validity =
generalizability of the research results SCIENTIFIC THEORY CONSTRUCTION AND TESTING
adaption
habituation-overstimulation, desensitization-graduated overstimulation
· Causal Inference =
he ability to make inferences by eliminating possible alternative explanations
measurement
hidden recording devices a "cache" in the wild
· Understanding/Creating Change =
identification of the causes or causal factors OR, an understanding of the relations at a deeper level than prediction
analysis of variance is based on
identifying sources of error variation and systematic variation in the data.
· Correlation research
in a survey does not involve variables, rational research is also a term used
product types
involve the assessment of the products owned or produced by a person/group/culture (skinheads and thrash metal, sports fans and memorabilia, caffeine consumption and beverage production).
use/non-use types
involve the use or non-use of something - a gain or loss in terms of natural or controlled use or non- use (cigarette butts, marks in textbooks).
A confederate...
is a research assistant who behaves in specified was to create an experimental condition.
· Scientific reporting
is unbiased and objective; clear communication of concepts occurs when operational definitions are used.
Ratio =
like interval, but with a true zero (time; want multiplicative properties for ratio purposes, temperature and time - depending on context)
Interval =
like ordinal, but with equal distance ("assumed" Likert Scales, 6"/12"/18"/24" - not including "0 inches")
· A THEORY
logically organized set of propositions that defines events, describes event relationships, and explains event occurrences. Theories guide research and research guides theories. Theories organize empirical knowledge. Theories vary in their scope and their level of explanation.
Field notes are records
made by trained observers that describe particular events and behaviors of interest rather than comprehensive accounts of behavior.
SURVEY METHODS Three methods for obtaining survey data
mail surveys, personal interviews, and telephone interviews.
The mean is A
measure of central tendency. The arithmetic average, the sum divided by the number of cases.
What are skewness
measure of the asymmetry of a distribution. The normal distribution is symmetric and has a skewness value of 0. positive skewness has a long right tail. negative skewness has a long-left tail. a skewness value more than twice its standard error is taken to indicate a departure from symmetry
what is kurtosis
measure of the extent to which there are outliers. normal distribution, the value of the kurtosis statistic is zero. Positive kurtosis indicates that the data exhibit more extreme outliers than a normal distribution. Negative kurtosis indicates that the data exhibit less extreme outliers than a normal distribution.
Meta-analysis uses
measures of effect size to summarize the results of many experiments investigating the same independent variable or dependent variable.
Indepdenent group t-test
measures the difference between the population means of 2 independent groups such as control and variable group
Quantitative measures of behavior use one of the four levels of measurement scales
nominal, ordinal, interval, and ratio.
unobtrusive
nonreactive
observer bias occurs when...
observers' expectations (expectancy effects) about behavior lead to systematic errors in identifying and recording behavior, and when
A biased sample
one in which the characteristics of the sample are systematically different from the characteristics of the population.
Ordinal
rank, order, unequal distance (1st/2nd/3rd place; "real" Likert Scales; temperature)
Rationale -
reactivity and subject response bias are reduced or eliminated. Researcher bias can be reduced and eliminated as well. Physical evidence adds to the multivariate structure of a research design.
Structured Observation
record behaviors that may be difficult to observe using naturalistic observation. observation of relations via 2-way mirror to assess behavioral patterns, assessing children's reasoning/developmental process interacting with nature (Piaget - how the "stage theory" evolved), using multiple observations of the same "subject phenomenon" (behavioral changes with different observers and/or confederates.)
three types of archival data
running records, other records include of many different types of public and private doc.and the news media/ popular press
· An IDEA
something imagined in the mind; with or without a purpose or a plan A CONCEPT is a thought or an idea, usually more well-defined than an idea
Problems and Limitations with Physical Traces
sources of bias must be investigated before concluding that a physical trace measure is valid. Validity can be enhanced by looking at convergent (similarities) and divergent (differences) evidence.
what is dispersion
statistics that measure the amount of variation or spread in the data include the standard deviation, variance, range, minimum, maximum, and standard error of the mean
The Hawthorne Effect
that when participants know they are being observed, they will behave according to their perceptions of how they "think" their behavior should match the goals of the observer(s).
· Control =
the extent to which the variables, at any level, can or are under the control of the study and results within the context of the nature of interest
· A correlation assesses
the extent to which two variables covary; the correlation coefficient is a quantitative index of the direction and magnitude of this relationship.
A moderator variable affects
the strength and direction of the relationship between two variables. In the case of the above example, moderators would be stress management and sleep. (Think about this with your own research ideas).
goal of correlational research
to assess "naturally" occurring relationships, usually with some sort of predictive purpose.
The first step in null-hypothesis testing is
to assume that the groups do not differ - that is, that the independent variable did not have an effect (the null hypothesis).
Why is important to run the min./max. statistics?
to identify any possible typos.
goal of observational data
to make "sense" of the data by constructing "groups" of data.
Validity
truthfulness
methods to control reactivity include...
unobtrusive, measurement, adaptation, indirect observations of behaviors
Ethologists
use naturalistic observation to describe innate patterns of behavior in animals and humans.
what are the two types of physical traces
use/non-use types and product types
paired t-test
used to describe whether the mean of the difference between the two variables is different from zero in the population.
analytical comparisons can then be
used to identify specific sources of systematic variation in an experiment.
· Unobtrusive measures
usually involve the indirect study of behavior. Often, participants are not present. Unobtrusive measures (physical traces, archival data) are often used to supplement and bolster existing direct observation and survey methods.
