visigoth.Experiment

class visigoth.Experiment(arglist=None)

Main object for controlling experiment execution.

__init__(arglist=None)

Initialize self. See help(type(self)) for accurate signature.

Methods

__init__([arglist])	Initialize self.
check_abort()	Check whether the quit key has been pressed and exit if so.
check_fixation([allow_blinks, fix_pos])	Enforce fixation but possibly allow blinks.
compute_performance()	Extract performance metrics from trial data log.
create_stimuli()	Initialize study-specific stimulus objects.
define_cmdline_params(parser)	Augment the command line parser to set params at runtime.
demo_mode()	Show stimuli and other aspects of the task prior to training.
draw(stims[, flip])	Draw each named stimulus in the order provided.
flicker(stim[, duration, rate, other_stims])	Repeatedly turn a stimulus off and on.
frame_range([seconds, frames, round_func, …])	Generator function for timing events based on screen flips.
generate_trials()	Generator that yields data for each trial.
initialize_data_output()	Define stem for output filenames and ensure directory exists.
initialize_display([gamma_correct, debug, …])	Open the PsychoPy window to begin the experiment.
initialize_eyetracker()	Connect to and calibrate eyetracker.
initialize_params()	Determine parameters for this run of the experiment.
initialize_server()	Start a server in an independent thread for experiment control.
initialize_sounds()	Create PsychoPy Sound objects for auditory feedback.
initialize_stimuli()	Setup stimulus objects.
iti_end(iti_duration[, check_abort])	Return True if current time is within a flip of the ITI end.
run()	Outer loop for executing the experiment.
run_trial(trial_info)	Execute an individual trial of the experiment.
save_data()	Write out data files at the end of the run.
serialize_trial_info(trial_info)	Serialize the trial results so they can be be sent to the remote.
show_feedback(stim, result[, idx])	Change the color of a stimulus to show feedback.
show_performance(mean_acc, mean_rt)	Show end-of-run feedback to the subject about performance.
shutdown_display()	Cleanly exit out of the psychopy window.
shutdown_eyetracker()	End Eyetracker recording and save eyetracker log files.
shutdown_server()	Cleanly close down the experiment server process.
sync_remote_params()	Update eyetracking params using values from the remote client.
sync_remote_screen(stims)	Send information about what’s on the screen to the client.
sync_remote_trials(trial_info)	Send trial information to the remote client for plotting.
trial_count([max])	Generator of trial index.
trial_info(**kwargs)	Generate a Series with trial information.
wait_for_exit()	Wait until the experimenter quits.
wait_for_trigger()	Wait for a trigger key (or an abort).
wait_until([end, timeout, sleep, draw, …])	Wait limited by callback and timeout, possibly drawing stimuli.
