Implementation of the official protocol --------------------------------------- **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.* The principal experimenter (Tracy Cheung, PhD candidate) leading the research project has experience programming psychological studies and collecting data with the E-prime software. Tracy has employed similar dual-task paradigm examining the ego-depletion effect (i.e., pencil & paper based E-cross task, & Stroop Task programmed in E-prime). Tracy as the principal experimenter will personally train the research assistants to conduct the replication study according to the official protocol. The research assistants will be trained to follow experimental protocol (Protocol_49TQVF), and will abide to the procedures as outlined by the Dutch translated version of Step-by-Step Procedure (Step-by-step_KY1792_NL). The Dutch-translated version of the Step-by-Step Procedure is based on the original English version (Step-by-step_KCWW2005). There will be one research assistant involved. The research assistant is a first year master's student in Psychology. When a participant arrives at the laboratory reception, a receptionist will direct him/her to the cubicle where the experiment is taking place. Once the participant is seated, the research assistant will then begin the experiment according to the procedures outlined by the Dutch translated version of the Step-by-step procedure (Step-by-step_KY1792_NL). **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.* To ensure the E-prime scripts run smoothly and that the research assistant is familiar with the experimental procedures, the research assistant will rehearse both conditions (control vs. depletion) once respectively with two individual lab members as if they were participants. During the pilot, the principal investigator (Tracy Cheung) will be present to ensure that all the experimental procedures are taken in line with the protocol and step-by-step procedure. **Experimenter knowledge of expected outcomes** *The person running a participant ("experimenter") is required to explain the tasks to the participant, so the experimenters won't be blind to the condition. Thus the only way demand characteristics might be entirely avoided is if the experimenter doesn't know about the ego depletion phenomenon. Please note whether this is the case for your experimenters, and in the Results component you can later note how you verified this, or whether the experimenter learned during the course of the experiment what the meaning of the conditions was* As the experimenter (research assistant) is a first year Psychology master's student, it is possible that she may have knowledge of the ego depletion phenomenon from her studies. Nonetheless, she has not been informed about the true purpose of this study, and in this sense unaware of the hypotheses in the current study. After data collection has been collected, the research assistent will be asked whether she is aware of the true purpose of the study. **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 recruited from the undergraduate participant pool made up of psychology students volunteering to participate for course credit or other undergraduate students participating for monetary compensation. Upon arrival at the laboratory, participants will be asked whether they are native Dutch speakers and their age. Only Native speakers and those who meet the age requirement of 18-30 years of age will be eligible to participate. **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.* *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 aim to collect data from 200 participants (i.e., ~100 participants per condition, which fulfills the sample size of the protocol). Upon arrival to the laboratory, potential participants will be asked whether they satisfy the demographic requirements of the protocol - that they are native Dutch speakers and that their age is within the range of 18-30 years. Those who do not satisfy these requirements will not be allowed to participate. On the other hand, in order to maintain a gender ratio of 30% to 70% female in the sample, we will aim to recruit 5 males and 5 females; or make sure at least there is a minimum of 3 females to a maximimum of 7 females for every block of 10 participants. The assignment of participants into the control vs. depletion condition will be based on pseudo-random assignment. This will be done using *Research Randomizer* to generate a list of condition assignments (100 participants to the control condition and 100 participants to the depletion condition), and randomzing the order of that list schedule. Participants will be recruited in blocks of 10, with 5 assigned to each condition and the order randomized, until both conditions meet the minimum required sample size. The anticipated sample size of 200 should compensate for having to exclude participants due to the exclusion criteria. If this does not suffice, then we will run blocks of 10 additional participants (with 5 participant assigned to each condition) 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).* Testing will be conducted at the laboratory of the Psychology department. Participants will be physically present at the laboratory to complete the experiment. Each participant will be assigned to a private cubicle, and complete the experiment on a Windows-7 PC desktop (equipped with 15-inch monitors, mouse, & keyboard) in isolation. E-prime (v.2) are installed on all PC’s
