![]() ![]() PsychoPy has Unicode support, so translating the task into other languages (Spanish, Polish, Japanese, etc.) only requires changes to these excel files. Block 5 (categories reversed) 40 TrialsĪll stimuli and instructions within the task are set via the stimuli.xlsx and task.xlsx files.However, the Inquisit IAT uses the older block layout of 20 trials in block 5. The contents of each screen follows the standard Inquisit IAT distribution very closely. The current version follows the block layout described in Nosek et al. ITI is set to 250 ms (see Nosek et al., 2007: the IAT at age 7).Indeed, all strings presented within the task are variables, so translating the task into other languages only requires changes to the stimuli and instructions files. All stimuli and instructions can be altered by editing the excel files.R script in the analysis folder produces D1 scores (and D1 scores for each stimulus category parcel), as well as accuracy and latency summary data.csv file is sufficient to most analyses (e.g., calculation of D scores). csv files are produced for each participant. However, it must be identical across categories. The number of exemplars can vary freely it's currently 6 but can be more or less without this affecting the block length.Block length is fixed by the code and the block_layout.xlsx file, and is independent of the number of stimuli exemplars.If you don't enter a participant number the task will crash and refuse to run!.Be careful that this counterbalancing does not covary with your counterbalancing of other experimental conditions. Odd numbered participants get the former, even numbered participants get the latter. The order of presentation of blocks within the task (e.g., whether participants get flowers-positive/insects-negative or flowers-negative/insects-positive first) is determined by the participant code.The escape key quits the task at any time.If using image stimuli, put a single space character in the appropriate column, as empty cells will cause the task to crash and Psychopy will throw an undefined variable error. To do this, edit the highlighted rows in the excel files: if using text stimuli, put "blank.png" in the appropriate image exemplar column in the stimuli.xlsx file. However, this implimentation can display any combination of words and/or images for both categories and attributes. The included stimulus file employs pictures as category stimuli and words as attribute stimuli.The task was written in version 1.82.01 but has been tested to run in later versions. ![]() py file that will run in the current PsychoPy version. psyexp file in either version and then compiling a. py file, you must use the Python 2 version of PsychoPy and not the Python 3 version.
