Platform for trajectory tracking experiments & data analysis
TrajTracker Paradigms
TrajTracker includes two off-the-shelf paradigms, which require only minimal configuration for running an experiment. Each of the paradigms supports a wide array of functionality. Some configuration parameters (e.g., how fast you must move) are set via simple and short python code, and other parameters (e.g., the list of stimuli to show) are set via CSV text files.
​
Each paradigm is created as a set of function and includes documentation; so you can easily add features to the off-the-shelf paradigm.
Number-to-position mapping
On each trial, one or more stimuli (text/pictures) are presented, and the participants drag their finger from a "start" point to the corresponding position on a number line. The number line is constantly displayed on screen and marked only with min/max values at its ends.
A trial is initiated by touching the "start" point in mid-bottom of screen. The target onset can be triggered either by the software (in which case the finger is expected to start moving at that time) or by voluntary finger movement.
Discrete choice
This is a dual-choice task: on each trial, one or more stimuli (text/pictures) are presented, and the participants drag their finger from the starting point to one of two response buttons.
A trial is initiated by touching the "start" point in mid-bottom of screen. The target onset can be triggered either by the software (in which case the finger is expected to start moving at that time) or by voluntary finger movement.
