(1966). "Generalized expectancies of internal versus external control of reinforcements". Psychological Monographs, 80, 1-18. ___________________________________________________________________________________________________________________ OVERVIEW ___________________________________________________________________________________________________________________ 23 2-FC questions regarding locus of control (external vs. internal) and 6 filler questions ___________________________________________________________________________________________________________________ DURATION ___________________________________________________________________________________________________________________ the default set-up of the script takes appr. 5 minutes to complete ___________________________________________________________________________________________________________________ DATA FILE INFORMATION ___________________________________________________________________________________________________________________ The default data stored in the data files are: (1) Raw data file: 'locusofcontrolscale.iqdat' date, time: date and time script was run with the current group/subjectnumber subject, group, session: with the current subject/groupnumber/session id build: the Inquisit build q*_response: response given (in assigned values) Scale: 0 (for internal choice) - 1 (for external choice) Note: external choice can be either a) or b) q*_latency: how much time (in ms) the participant spent on the surveypage with this particular question (the last time this particular surveypage was visited) (2) Summary data file: 'locusofcontrolscale_summary.iqdat' (Inquisit Lab: one data file per participant) inquisit.version: Inquisit version run computer.platform: the platform the script was run on (win/mac/ios/android) startdate: date script was run starttime: time script was started subjectid: assigned subject id number groupid: assigned group id number sessionid: assigned session id number elapsedtime: time it took to run script (in ms); measured from onset to offset of script completed: 0 = script was not completed (prematurely aborted); 1 = script was completed (all conditions run) textbox.age.response: contains the response to the age question (if answered) radiobuttons.gender.response: contains the response to the gender question (if answered) IEscore: contains the total IE score = number of EXTERNAL choices IEscore_percentile: contains the percentile (see Rotter, 1966, Appendix B, Table B1, percentiles calculated across male/female frequency) IEscore_percentile_gender: contains the percentile by gender (see Rotter, 1966, Appendix B, Table B1) if gender is known (otherwise => "not determined") ___________________________________________________________________________________________________________________ QUESTIONNAIRE SET-UP & SCORING ___________________________________________________________________________________________________________________ 23 2-FC questions regarding locus of control and 6 filler questions - the total score is the number of external choices - percentiles calculated based on data published by Rotter (1966) (gender-specific) ___________________________________________________________________________________________________________________ INSTRUCTIONS ___________________________________________________________________________________________________________________ main instructions were taken from Rotter (1966) and adapted to the computer; edit under section Editable Parameters ___________________________________________________________________________________________________________________ EDITABLE CODE ___________________________________________________________________________________________________________________ check below for (relatively) easily editable parameters, stimuli, instructions etc. Keep in mind that you can use this script as a template and therefore always "mess" with the entire code to further customize your experiment.
