Implementation of the official protocol --------------------------------------- > We have read the the new documents of the protocol (Protocol_49TQVF), the step-by-step procedure (Step-by-step_KCWW2005) and the running eprime tasks. **Experimenters** *Please describe the qualifications/training of those who will be conducting the testing, and how they were trained on the protocol. Note any expertise with the topic area or methods used in this study.* > Two trained female research assistants will serve as experimenters. The > experimenters have experience in collecting experimental psychology > data. Due to conducting previous experiments, the experimenters have > extensive experience in interacting with participants. For training, > the experimenters have read the step-by-step procedure. During > experimentation, each experimenter has the step-by-step procedure > provided on a handsheet. Prior to data collection, the experimenters > have been trained in the proposed methods by testing the procedure > together with the investigator, by testing the procedure alone, and by > testing the procedure with pseudo participants. The experimenters will > be naive to the meaning of the experimental conditions. They do not know the topic of the study or any hypotheses about it. After data-collection, experimenters will fill out a questionnaire on what the experimenter thought the hypothesis was and the meaning of the experimental conditions. Responses will be included in the lab log. **Piloting / training** *Piloting should be done prior to registration of this plan -only after registration of this plan will participants' data be included in the final dataset. Please indicate here who in your lab has piloted the experiment and what they did - ran a pilot participant, ran another lab member as if they were a participant, etc.* > Piloting has been conducted on April 14th. The two experimenters were instructed by two members of the lab (i.e., Katrin Rentzsch and Dario Nalis) on how to follow the step-by-step procedure. Both experimenters first piloted the experiment for themselves. Then, the experimenters ran each other as pseudo participants. Later, each of the experimenters tested the procedure by running an(-other) undergraduate student assistant who has not been involved in the study at all. **Recruiting** *Explain how and from where the participants will be recruited. The study should be described as being on “word and number recognition and reaction time”* > Participants will be contacted via mailing lists and announcements in undergraduate lectures in psychology, business, and information technology including information on the study (described as being on “word and number recognition and reaction time”) as well as requirements for participation. Incentives for participation include monetary reimbursement of 7 Euros per participant or partial course credit. Participants will be given the choice of receiving partial course credit or receiving monetary reimbursement. Usually, psychology students receive partial course credit, whereas students from different subjects receive monetary reimbursement. We will code the incentive for each participant and include it into the data file. We expect that about 70 participants will receive monetary reimbursement and about 50 participants will receive partial course credit. **Sample, subjects, and randomization** *Please add details about the planned number of subjects (must be more than 50 in each of the two conditions) in terms of the stopping rule for the data collection, including how you will ensure that they meet the demographic requirements of the protocol (e.g. you will keep running participants who self-register from your subject pool, in blocks of 10, until you have more than 50 in each condition that are 18 to 30 yrs old and until between 30% and 70% are female), how you assess whether the subject had English as their native language, etc.* > When announcing the study, potential participants will be informed about the requirements for taking part at the study, i.e. only participants with German as their native language and participants between 18 to 30 years old may participate at the study. When registering for the study on a website, participants will be asked whether they meet the requirements. Only participants who meet the requirements will be selected for the study. 150 participants are intended to register on the website. Due to the fact that business and information technology include more than 50% of male students whereas psychology includes less than 50% male students, we are certain that the percentage of female participants in the final sample will be about 50%. Additionally, at the beginning of each session, the experimenter fills out a short questionnaire recording only the participant's age, gender, and native language. Participants who do not meet requirements will be excluded from the final data set. Participants will be tested in blocks of 10, in order to reach a sample size of 60 participants in each of the two conditions (Based on previous experience with conducting experiments in university settings, we expect a dropout of 20% of all registered participants). Participants will be debriefed via email after the entire experiment has been completed, and not as each participant finishes, to prevent contamination by word-of-mouth. *Will you use truly random assignment (flip a coin for each subject that comes in) or, e.g. generate a sequence containing 50 of each condition in random order and assign subjects based on the sequence until you run all 100? Give details. How will you collect additional data if some Ss have to be excluded? e.g. running blocks of 10 additional participants (with 5 assigned to each condition) until both conditions have at least the minimum sample size* > We generated 20 sequences of random numbers that assign participants to one of the two conditions in a block of 10 (with 5 in each condition), using pseudo-random assignment based on a computer program that generates random numbers (http://rechneronline.de/zufallszahlen/). We expect that out of the 20 sequences, only 12 will be used (i.e., 12x10 => 60 participants in each condition). However, if some subjects have to be excluded, we will run blocks of 10 additional participants until both conditions have at least the minimum sample size. **Setting/Lab/Equipment** *Please add a detailed description of the testing environment. Include details of any equipment/computers you will use. Please indicate the version of the EPRIME software are your machine(s).* > Participants will be tested in isolation, one participant per room per experimenter. All participants will work on the same type of desktop-computer (laptop, Intel core I5 2.6 GHz, 8 GB RAM, Windows 7 Professional) which is connected to a wide-screen monitor (acer V243PH, 23.6") and keyboard (Logitech K200). E-Prime runtime license will be used. Participants ring a bell in order to call the experimenter who will be sitting outside, but in front of the room.
