Variables and Confoundings

A social psychologist wants to test the implications of a theory of personal space. He thinks that people will differ in their reaction to others who intrude in their personal space depending on the perceived status of the intruder. Specifically, he predicts that people who are viewed as having higher status in some way will be permitted to move closer than those who are not viewed as having higher status. Thus, the investigator arranges to conduct an experiment in which he uses undergraduate students as participants and manipulates status by controlling the manner in which individuals are introduced to a participant. Confederates of the researcher (all male graduate student research assistants) are introduced as observers in one of three ways, as: “an undergraduate student working for the psychology department”; “an undergraduate honors student working for me” (i.e., the faculty member); or “a graduate student working for me.” Prior to testing any participants, three different confederates are randomly assigned one of the three roles to play and subsequently keep that same role throughout the experiment. Students are scheduled in groups of three and are assigned randomly to one of the three introduction conditions when they appear for the experiment. Each participant is taken to a different small room with two chairs, supposedly to work on an experimental task. The psychologist introduces the confederates to participants while they are working on their tasks. After being introduced to each participant, the confederate-observer takes the second chair and places it within 6 inches of a participant, makes what looks like observations for 5 minutes, and then leaves. The confederate-observer actually measured how many participants moved their chairs away, even slightly, when he moved next to them. After many individuals are tested in this manner, the psychologist finds that significantly fewer people adjusted their seating position when the observer was introduced as a graduate student than when the observer was introduced as an undergraduate. There is no difference in the number of moves made by participants in the two conditions in which the observers were introduced as undergraduates. The investigator concludes that his hypothesis was supported.

Threats and Eliminating Them

A psychologist believes that people are either “auditory learners” or “visual learners.” Specifically, she thinks some people remember information better when it is presented auditorily and others remember information better when it is presented visually. She tests her theory by asking undergraduate students to study and remember a list of words presented on a tape recorder (auditory) or on a sheet of paper (visual). To find out whether people are primarily auditory or visual learners, one week prior to the experiment a colleague asks students in a large introductory psychology class to fill out a long, involved questionnaire about attitudes, beliefs, etc. Buried in the questionnaire is a question about the student’s most preferred mode of learning, that is, visual or auditory. When students come later for the memory experiment, two different lists of 20 words are presented for study. Unknown to the students, the psychologist uses the information from the questionnaire to identify which mode of presentation is preferred by each student. Each student is tested first under his or her preferred mode of study and then under his or her non-preferred mode. Although the manner in which the words are presented changes for each student, everything else is held constant. That is, the same 20 words are always used for the preferred mode of presentation and for the non-preferred mode of presentation, the length of time the words are presented is the same, as is the retention interval, and so forth. The psychologist finds that the average recall in the preferred mode is significantly better than the average recall under the non-preferred mode. She believes the results support her hypothesis.

PSY/410 Programmatic Assessment Abby is a 20-year-old female college student. For at least the last 3 months Answer

 

1.Abby is a 20-year-old female college student. For at least the last 3 months, Abby has experienced ongoing anxiety and worry without a specific cause for these feelings. She has been restless and has noticed that her muscles feel tense and that these symptoms are beginning to affect her behavior in a way that is causing her to become distressed and that it was normal to feel a little anxious sometimes; however, as the semester has progressed, she has not begun to fell significantly more comfortable. On the recommendation of a friend, Abby visited the university’s counseling center and talked to Dr. Smith. Dr. Smith was warm and welcoming and, after discussing her concerns. Dr. Smith listened attentively and asked Abby a few questions. They both agreed on an appointment date and time for the next week. Dr. Smith gave Abby a homework assignment to keep a written log of the negative thoughts or assumptions she has during the week and the circumstances under which those thoughts occurred. Abby was asked to bring the log with her to her next appointment.
