I need help figuring out which analysis's work best for these there scenarios. For study one should I use an Independent sample approach. For study 2 an one way or two way ANOVA and for study 3 should I use ANOVA or Pierson correlation?
7:35 4 Scenario_1_Descript... Q . . . Scenario 1 Description Scenario 1: Response Inhibition & Alcoholism Field: Experimental Psychology You are an experimental psychologist interested in behavioral phenotypes related to alcoholism. You've been studying factors that affect how well people are able to suppress inappropriate actions (i.e., response inhibition). You suspect alcoholics may have impaired response inhibition based on their inability to refrain from drinking to excess and in inappropriate situations. The first study you conducted used a random sample of 30 alcoholics compared to 30 control participants. Both groups completed a goo-go task (Interactive task example; Informational Resource). In your version of the task, participants focus on the white dot in the center of a computer screen. Then a green square (go signal) or red square (stop signal) appears. If the green square appears, they have to press the spacebar as fast as possible, but if the red square appears, they have to not press the spacebar. You repeat this sequence 50 times (i.e., 50 trials) with the red square occurring on 20 randomly selected trials and the green square on 30. Then you measured the number of times they press the spacebar when the red square appears (i.e., failed response inhibition). You hypothesized that the alcoholics will have worse response inhibition represented by more errors. The results for each individual participant are in S1S1Data.csv. This .csv file has three columns identified by the first row in each column. ID is a nominal identifier for each unique participant. Group is whether said participant is in the alcoholic or control group, and IF is the number of inhibition failures. Screen 1 60% of Trials 40% of Trials Screen 2 Must press spacebar Must NOT press as fast as possible spacebar Figure 1: Screens seen by participants in first experiment's goo-go study on an individual trial. You followed up with a second study where a group of 30 randomly sampled alcoholics completed a modified version of the task. Each participant was exposed to two conditions in a counterbalanced order. In the first condition, the task was exactly the same as it was in the first experiment. In the second condition, the task's stop signal was modified. Instead of a red rectangle telling participants not to press the spacebar, a picture of a glass of beer was shown. You have hypothesized that an alcohol cue may disrupt the alcoholics' ability to successfully inhibit the response, and in that condition more inhibition failures should occur. You gave each participant 50 trials under each condition and measured the number of failed response inhibitions. The data from this study is in S152Data.csv. This .csv file has four columns identified by the first row in each column. ID is a nominal identifier for which subject the data came from. Order is the order of the counterbalancing (Order 1=Alcohol cue condition first; Order 2=Neutral Cue condition first). Condition is the condition the data in that row are from (Neutral = red rectangle no go cue; Alcohol = beer glass no go cue). is study source was downloaded by 100000846561265 from CourseHero.com on 05-03-2022 07:35:30 GMT -05:00 ps://www.coursehero.com/file/9681 1790/Scenario-1-Description-Final-2docx/ Scenario 1 Description OThis study source was downloaded by 100000846561265 from CourseHero.com on 05-03-2022 07:35:30 GMT -05:00 https://www.coursehero.com/file/9681 1790/Scenario-1-Description-Final-2docx/ Scenario 1 Description Screen 1 60% of Trials 40% of Trials Condition 1 Screen 2 Must press spacebar Must NOT press spacebar Screen 1 60% of Trials 40% of Trials Condition 2 Screen 2 Must press spacebar Must NOT press spacebar Figure 2: Screens seen by participants in second experiment's goo-go study on an individual trial. After you completed the second experiment, you wanted to replicate it while also improving on the design. You decided to add a third condition to control for if a reward cue, as opposed to specifically an alcohol cue, disrupts response inhibition. In the third condition, the stop signal is now a picture of candy bars. However, you were worried about participant fatigue. To solve this problem, you used three different groups of participants. Each participant is only involved in a single condition and had 50 total trials. You hypothesized that while using a reward cue as a stop signal will increase the number of errors, it will not result in as many errors as the alcohol stop signal. The data for this study is in S153Data.csv. This .csv file has three columns identified by the first row in each column. ID is a nominal identifier for each subject. Condition identifies which condition the data in that row come from (Neutral = Red rectangle no go cue; Alcohol = Beer glass no go cue; Candy = Candy bars no go cue).
