Below are 5 hypothetical factorial studies. To complete this Lab assignment: 1. I want you to open up an excel spreadsheet. 2. Enter the cell means like I showed on the previous pages you just read 3. Create a graph 4. For each effect (2 main effects and the interaction) you must do two things: 1. State whether the effect is significant:yes or no 2. Describe the nature of the effect (see my example on the previous page) 5. You can put all 5 tables, graphs, and descriptions on one spreadsheet. 2 Cin the film na Anto Lo Vauramall and cushmit it Study #1 A researcher is interested in the effects of gender and intelligence on Conversational style. Half of the participants were male and half were female. Within each ender, half had high IQ scores and half had low IQ scores. The dependent variable was the number of times the participant interrupted a confederate during a 10 minute conversation. These are the finding Gender Low IQ High 10 Male 8 8 Female 5 Study #2 A researcher was interested in the relation of gender and assertiveness to perceived "conventionality. Participants in an experiment watched videotapes of actors interacting with a job supervisor, then rated the actor's conventionality on a scale of 1 to 10, where 10 indicates very conventional and 1 indicates very unconventional. The Independent variables in the study were (a) gender of the actor and (b) behavior toward the supervisor (assertive or submissive). Here are the results: Assertive Submissive Male Actor 7.5 Female Actor 6.0 7.5 Study #3 A psychologist was interested in the effects of meaningfulness and amount of material on memory Participants took part in an experiment in which they learned lists of meaningful or meaningless words. The independent variables were (a) list length (short or long) and (b) type of material (meaningful or meaningless). The dependent variable was the percentage of words recalled after one week. (Note possible floor effect) These are the findings: Short List Long List Meaningful 60 Meaningless 35 Study #4 An experimenter examined the effects of familiarity and display clarity on the ability to recognize words. Participants viewed 100 words, presented on a slide projector, and read them aloud as quickly as possible. The first 25 words were familiar words and were presented in focus. The second 25 were unfamiliar and presented in focus. The third 25 were familiar and out of focus. The final 25 were unfamiliar and out of focus. The dependent variable was reaction time in milliseconds. Here are the findings: Familiar UnFamiliar Clear|500 560 Fuzzy 620 1950 Study #5 A researcher wanted to study the influence of various breakfast foods on participants ability to concentrate. Half of the participants were given regular coffee, and half were given decaf coffee. In addition to this "caffeine IV" the researcher randomly assigned each participant to one of three levels of a "breakfast food IV". One third of the participants ate no breakfast, one third ate a small breakfast (a donut), and one third ate a large breakfast (bowl of cereal, some fruit, and toast). The dependent variable was the score on a concentration test that ranged from 1 to 100 (with 100 being a perfect score). Here are the findings: None Small Large No Caffeine 20 20 30 Caffeine 145 55 80
