Recent Releases of @kurokida/jspsych-psychophysics

@kurokida/jspsych-psychophysics - V4.0.0 Compatible with jsPsych version 8

New Features

  • Added event handlers for screen touch (touchstart/end/move/cancel). Refer to touch_drawing.html.
  • Support for multi buttons which is same functionality as button grid of html-button-response.
  • Added upper_prompt and lower_prompt parameters.

Changes

  • Accessing the canvas, context, and center positions using jsPsych.getCurrentTrial() is no longer possible. Use the following method instead. Considering window.devicePixelRatio is probably unnecessary if you use the PIXI mode.

javascript const canvas = document.getElementById("myCanvas"); const context = canvas.getContext("2d"); const centerX = canvas.width / 2 / window.devicePixelRatio; const centerY = canvas.height / 2 / window.devicePixelRatio;

  • stim_array can not be used. Use jsPsych.getCurrentTrial().stimuli[n].instance instead. See changeimagesizebykeypress.html
  • The numeric has been discontinued. See https://jspsychophysics.hes.kyushu-u.ac.jp/gabor/

Issues

Following the demo programs have issues, but no solution has been found yet. Some of them are likely related to https://github.com/jspsych/jsPsych/discussions/3513.

@kurokida/jspsych-psychophysics - V3.7.0 verified accuracy

This version was used to verify accuracy. According to my observation, presentation times should be specified in terms of frames not milliseconds, and the use of Firefox should be avoided for experiments with brief presentation times of less than 50 ms/3 frames.

Changes

Add new properties "pixiangle" and "pixirotation" to the text object

New demo program

piximentalrotation.html This uses PixiJS library to rotate the stimulus charactor.

@kurokida/jspsych-psychophysics - NPM package

Thanks to @bjoluc, the jspsych-psychophysics plugin supports the NPM package from this version.

New demo

Changes

The default method to calculate the gaussian filter is the 'numeric' library, but you can select the 'ml-matrix' library instead. The 'math' library is no longer supported since this version. See the help of the method at https://jspsychophysics.hes.kyushu-u.ac.jp/objectProperties/#obj_type-gabor.

Compatible with jsPsych 7.3.1

New features related to Pixi.js

New features related to Canvas

  • The remain_canvas property. If this is true, the main canvas remains for the next trial. This is useful to present complex stimuli using multiple psychophysics objects. Note that this property doesn’t work in the Pixi mode.

@kurokida/jspsych-psychophysics - v1.4 is released

New Features

Button response

Participants’ responses can be captured using buttons in addition to the mouse and keyboard. Set the response_type property as 'button'.

Event handlers

You can specify the mouse/keyboard event handler. For example, you can make a program in which a participant change the luminance of a stimulus pressing the ArrowUp/ArrowDown key, and finish the trial pressing the space key.

clear_canvas property

If true (default), the canvas is cleared every frame. There are not many cases where this should be false, but if you want to draw the trajectory of the mouse, for example, you need to set it false.

@kurokida/jspsych-psychophysics - Bug is fixed.

The keyboard Listener is canceled properly.

jsPsych.pluginAPI.cancelKeyboardResponse(keyboardListener);

Below v1.0, it is not canceled properly due to the scope of the keyboardListener variable.

@kurokida/jspsych-psychophysics - v1.0 is released

To specify timing information in terms of frames not of milliseconds, the show_start(end)_frame property is added. To enable the properties, the is_frame property should be also specified as true.

Note that the display duration do not necessarily correspond to the intended value. For examples, see Bridges et al. (2020).

About how to use the show_start(end)_frame property, see the demonstration files. - movingCircles_frames.html - twoImagesWithSOAinFrames.html

@kurokida/jspsych-psychophysics - v0.4 is released

New demos

demos/drawpartof_image.html

This file demonstrates how to use the drawFunc with an image. The image is preloaded automatically. In this demo, the part of the image is presented, and moved from left to right.

demos/drawtwoimages_repeatedly.html

This file demonstrates how to present two images repeatedly until a participant responds to them. This demonstration can be applied to the study on like change blindness.

Changes

The drawFunc can be used in an image object.
