Implementation of the official protocol Protocol_49TQVF; Step-by-step_KY1792 --------------------------------------- **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.* Training of the research protocol, including ethics, will be provided to experimenters who will be conducting the testing by all authors. Experimenters are chosen based on the following criteria: GPA more than 3.0, familiarity with psychology experiments and research methods, statistics, and good communication skills. **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.* At the moment, the authors have completed the adaptation (translation and back translation) of research materials and protocol. Piloting has been conducted twice, on Feb 13 (10 participants, using lab members) and Feb 20 (10 participants, using undergraduate students). Piloting was conducted by the experimenters, supervised by all authors. **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* Although the researchers cannot ensure that the experimenters do not have prior knowledge in ego-depletion and self-control, to minimise bias, these variables will not be mentioned during the recruitment and training of experimenters. **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”* Undergraduate participants will be invited through leaflets and posters on campus to participate in a study investigating “word and number recognition and reaction time”. **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 plan to recruit a number of 168 participants. Subject criteria based on the protocol will be strictly followed: undergraduate, age range 18-30 y.o., native Indonesian. Equal numbers of participants will be allocated to each condition using a random order generator (84 in each of the two conditions, crossed with participants’ sex). In case some participants have to be excluded, additional data will be collected by running 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).* Individual participant will be tested in isolation in a laboratory cubicle. Each cubicle is provided with a PC of 23 inch monitor running on Windows 8.1. For data collection, we will require a ‘Run Time’ license for E-Prime 2.0.
