Review Questions

1. An experimenter gives each of three participants a list of words to study. Participant A is given an hour to study the list, participant B is given 10 minutes to study the list, and participant C is only given 1 minute to study. A day later the participants are called back to the lab to restudy the list until they are able to recall it fully. Participant A doesn’t show up and the experimenter gives them an unexcused no-show on Sona while crying. Between participants B and C, who would need more time to re-study the list? Who would spend more time studying total? What concepts are associated with this experiment?

2. Oh no! It’s time for the PSYCH20A final and you haven’t had time to study the book chapters! You read them when they were assigned but haven’t looked back at them since. You should: a) Re-read the chapters until they seem familiar b) Use the study guide and your friends to quiz yourself

MAFIA EXPERIMENT

MAFIA EXPERIMENT You are all participants and experimenters in an experiment. I am the PI. In this experiment the experimenters are hiding amongst the participants and kick them out of the study one by one. The participants all have a type of amnesia. Each round consists of a lab meeting and a trial. Lab meetings are when the experimenters choose which participant to kick out, and on some rounds a participant can ask the PI if someone is an experimenter. A trial is where the whole group discusses who they think an experimenter is and can vote to eliminate one person from the study. The goal of the experimenters is to kick out all participants, thus showing that patients with amnesia perform less well on party games. The goal of the participants is to out all the experimenters as fast as possible to collect their compensation. 1 Tap = Experimenter -You have perfect memory for all events. Try to blend in amongst the participants. 2 Taps = Anterograde Amnesia -You can remember the past, but cannot encode new memories. During each lab meeting there will be an opportunity to remember when you signed the consent form and as a group can point to one person and ask if they are an experimenter. As omniscient PI, I will tell you. During trials, you may only accuse individuals and cannot reference past trials. 3 Taps = Retrograde Amnesia -You can encode new memories, but cannot remember the past. You must keep your eyes closed during lab meeting, but can remember events from past trials and bring them up during discussion.
