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 "pixi_angle" and "pixi_rotation" to the text object

New demo program

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

NPM package

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

New demo

change_image_size_by_keypress2.html

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.

Version 3.5.0

Compatible with jsPsych 7.3.1

New features related to Pixi.js

• Image rotation See demos/pixi_scale_rotate.html
• Masks and Filters See pixi_image_mask_filters.html

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.

Compatible with jsPsych 7.3.0

This release is compatible with jsPsych 7.3.0, and includes the jsPsych library.

Simulation modes are supported

New features

The plugin supports simulation modes

See the following demos

• simulation-data-only-mode.html
• simulation-visual-mode.html

Changes

The response property has a proper value when a button is clicked as a response.
See help on data generated.

Compatibility with jsPsych

The plugin includes jsPsych version 7.2.1.

PixiJS is supported

New features

Starting with version 3.2.0, the psychophysics plugin can present visual stimuli using PixiJS functionality. See this page in detail.

Bug fixes

Visual stimuli are properly presented on very large resolution displays.

Version 3.1.0

New properties

The image width/height can be specified in pixels.
See https://jspsychophysics.hes.kyushu-u.ac.jp/objectProperties/#obj_type-image

The contrastPreMultiplicator property is added.
See https://jspsychophysics.hes.kyushu-u.ac.jp/objectProperties/#obj_type-gabor and CreateProceduralGabor.

Compatible with jsPsych V7.

This release is now compatible with jsPsych V7.

This release includes jsPsych 7.1.2.

Note for users of previous versions.

At first, please see Migrating an experiment to v7.x

• Write const jsPsych = initJsPsych({}) at the begging of the script.
• Write type: jsPsychPsychophysics in a trial object.
• Pass the trial object as an argument as follows jsPsych.run([instruction, trial])

Support for retina display

In higher resolution displays, such as retina displays, stimuli are now presented more clearly.
See jspsych/jsPsych#2097

Bug fix concerning the compatibility with the fullscreen plugin.

Fixed the canvas to be fullscreen when using the fullscreen plugin.
With this change, the canvas_offsetX and canvas_offsetY properties have been added.
