front 1 Why rigorous research methods are necessary in psychology, Aspects of research that are easier and harder in psychology than in other fields | back 1 - Theory of mind: It’s easy to make assumptions about why - Situational behaviors - Placebos are harder - Realism: more challenging to create psychologically realistic scenarios Ex: couple's behavior - Ethics: some things cannot be ethically manipulated to show cause and effect - Culture: plays a profound role in social rules, interpersonal relationships and method of learning |
front 2 Construct, operationalization/operational definition, and the relationship between them Ability to apply these definitions Ability to generate your own operational definitions and discuss pro’s and con’s of that definition | back 2 Construct: A hypothetical process or characteristic Ex: self-esteem Operational definition: A procedure for defining and measuring a construct Ex: Rosenberg's self-esteem scale |
front 3 Pro’s/con’s of using previously established measures/instruments as your operational definition of a construct | back 3 Pro's: Ability to compare your results to other studies in the field, known strengths & weaknesses (including reliability & validity), can take decades to develop a single measure & the work is already done for you Con's: Maybe expensive, known weaknesses |
front 4 Find, identify, and explain the purpose of information about operational definitions/measurement in the introduction/method sections of an empirical article; definition of an empirical article | back 4 An empirical article is a scholarly report of a research project (observation, description, and/or manipulation) The most valuable empirical articles are those that come from peer-reviewed journals |
front 5 Read a news report about empirical research and identify important questions about operational definitions and measurement procedures that would be important for interpreting the research results | back 5 no data |
front 6 Factors that affect reliability of a measure: most common sources of error | back 6 - Observer error: problems with the recorder of the data - Environmental changes: something in the environment that affects performance - Participant changes: something in the participant that affects performance |
front 7 Scales of measurement (nominal, ordinal, interval, ratio), examples of each, and implications/properties/uses of each | back 7 - Nominal: categories with different names but are not related to each other in any way Ex: psychologist, psychiatrist, social worker - Ordinal: categories that have some relationship and are usually sequential, Likert scale Ex: tall, grande, venti - Interval: sequential categories of the same size, but with an arbitrary 0 point, most common in psychology Ex: IQ Scores, fahrenheit scale - Ratio: sequential categories of the same size, but with a meaningful 0 point expressing lack Ex: height, weight, age, kelvin scale |
front 8 How the operationalization of a large measure or instrument usually works (use of multiple-item scales, use of averages, subscales, etc.) and why it would be used How/why citing a scale is an operational definition | back 8 When your construct is something like “intelligence,” then, you are usually operationalizing that construct through a summary or total score on a particular instrument, or the score on a particular subscale therefore, the measure you use is the operational definition |

front 13 Floor and ceiling effects | back 13 Floor Effect: When the range of possible responses on your measure do not go low enough, for example, if you are giving an IQ test, but the “easiest” items are too hard for the clients you are testing, all clients may get a score of 0 on the measure, which may disguise significant differences between them Ceiling Effect: When the range of possible responses on your measure do not go high enough, for example, if you are giving test in PSYC 311, but the “hardest” items are too easy for the students you are testing, all students may get 100% on the test, which may disguise significant differences in understanding of the material |
