  • many updated dependencies in the Standalone apps
  • many bug fixes (including several memory errors)

New in PsychoPy 1.84.0 RC 5 (Jul 8, 2016)

  • ADDED: Projects menu, which can sync files with Open Science Framework
  • ADDED: new Builder experiment setting to specify the version of PsychoPy to be used when running the experiment #1137
  • ADDED: Movies in Builder can now avoid loading audio (i.e. mute). As well as meaning your movie is genuinely silent this saves pocessing for the computer, so do it unless you need the sound!
  • ADDED: menu item to create a .csv (data) file from a .psydat file; see Coder > Tools menu (also: Coder > Demo menu)
  • ADDED: Builder experiments force a save before the end of the study so pressing the red stop button is less likely to lose data for you
  • CHANGED: setting ShapeStim vertices dynamically now requires an explicit assignment of the new vertex list to shape.vertices; this can be slow for filled shapes with many vertices. See shapes.py, selfx example.
  • FIXED: window viewScale and viewPos combine correctly; viewScale handles negative values, mirror-image flips the window correctly (except for Text)
  • CHANGED: Some file names and locations have changed. To update, replace OLD form in your scripts with NEW form: OLD form –> NEW form Deprecated since 2012, must now update: from psychopy import calib –> from psychopy import monitors as calib (or just use monitors) from psychopy import bits –> from psychopy.hardware.crs import bits from psychopy import log –> from psychopy import logging Newly deprecated (the old way still works but logs a warning): from psychopy import _shadersPyglet –> from psychopy.visual import shaders from psychopy import gamma –> from psychopy.visual import gamma from psychopy import filters –> from psychopy.visual import filters API change (only affects people who write their own Builder components): from psychopy.app.builder.components._visual import VisualComponent –> from psychopy.app.builder.components._base import BaseVisualComponent
  • CHANGED: PyQt is now default over wx for dialog boxes (if either PyQt4 or PyQt5 are installed). Also fixed bug to support PyQt5
  • IMPROVED: ShapeStim can properly fill arbitrary shapes (using tesselation); see new shapes.py Coder demo for examples.
  • FIXED: Builder experiments will always add their extension (to stop people overwriting them with the python script of the same experiment)
  • FIXED: faster writing of multiple lines (bits) to the LabJack
  • FIXED: sampling rate when using binocular mode in eyelink 1000 #1146
  • FIXED: Aperture now supports infinite durations in Builder #1122
  • MAJOR REFACTOR: A lot of code has been refactored to be more in line with a thing called PEP8. If that doesn’t mean anything to you don’t worry, it shouldn’t affect you. If you like that sort of thing, sorry we didn’t got further and get rid of camelCase.
  • FIXED: ColorCal II now supports newer pyserial version #1138

New in PsychoPy 1.84.0 RC 4 (Jun 17, 2016)

  • CHANGED: setting ShapeStim vertices dynamically now requires an explicit assignment of the new vertex list to shape.vertices; this can be slow for filled shapes with many vertices. See shapes.py, selfx example.
  • CHANGED: minor: Aperture, Polygon, and Rect now depend on BaseShapeStim (i.e., their base class has a new name, no change in function)
  • FIXED: window viewScale and viewPos combine correctly; viewScale handles negative values, mirror-image flips the window correctly (except for Text)
  • CHANGED: Some file names and locations have changed. To update, replace OLD form in your scripts with NEW form: OLD form –> NEW form Deprecated since 2012, must now update: from psychopy import calib –> from psychopy import monitors as calib (or just use monitors) from psychopy import bits –> from psychopy.hardware.crs import bits from psychopy import log –> from psychopy import logging Newly deprecated (the old way still works but logs a warning): from psychopy import _shadersPyglet –> from psychopy.visual import shaders from psychopy import gamma –> from psychopy.visual import gamma from psychopy import filters –> from psychopy.visual import filters API change (only affects people who write their own Builder components): from psychopy.app.builder.components._visual import VisualComponent –> from psychopy.app.builder.components._base import BaseVisualComponent

  • CHANGED: remove support for google’s speech to text (the new google API is for chrome / chromium developers only)
  • CHANGED: deprecate psychopy.web.upload(); use the requests package instead: requests.post()

New in PsychoPy 1.83.00 (Oct 23, 2015)

  • ADDED: MovieStim3 using an alternative backend that doesn’t require avbin, vlc or streamer. It just uses a couple of python libs and FFMPEG, which are relatively easy to package. Seems to have good performance too but this needs more testing
  • IMPROVED: speed to load psychopy.visual (“lazy loading” only the stimuli you use are loaded)
  • ADDED: RatingScale precision=60 allows display of time-based values (min:sec or hours:min). Values from .getRating() are decimal proportions (1 min: 59 seconds -> 1.9833 minutes).
  • ADDED: Coder view can now be set to read-only mode to prevent subjects accidentally altering study #945
  • ADDED: TextStim now has property boundingBox telling you the maximum area of the letters (defined by the font, not by the actual rendered letters) #35c168f1
  • ADDED: Aperture can now be created using images (anything that worked with ImageStim) #923 and can also be inverted so that opaque becomes transparent and vice versa #922 Thanks Thomas Emerling for both
  • ADDED: New visual stimulus EnvelopeGrating for contrast-modulated gratings. Thanks Andrew Schofield
  • ADDED: option to set mouse_exclusive mode (mouse locked to the window boundary and invisible) Thanks Suddha Sourav #898
  • FIXED: DotStim can now change field size on the fly
  • FIXED: several (but probably not all) annoying error messages that were unimportant
  • FIXED: Condition file in Builder no longer abbreviated. Thanks Mike #913

New in PsychoPy 1.82.02 (Oct 23, 2015)

  • FIXED: TrialHandler wasn’t saving extraInfo (was overwritten during trials) #815

  • FIXED: problem with microphone saving files that end with w, a or v #875
  • FIXED: MonitorCenter failing to create new monitor #887
  • FIXED: universal line endings in csv outputs files #889
  • FIXED: unicode in conditions files #892
  • FIXED: iohub not detecting Linux mouse events #894
  • FIXED: if output file is set to be stdout this should then be closed #902
  • FIXED: don’t abbreviate the path name of conditions files #913
  • FIXED: minor error in logging for rush() under win32 #914
  • FIXED: unicode issues in user preferences panel #930 #932
  • FIXED: MonitorCenter won’t lock you out if given an invalid screen number #937
  • FIXED: mono++ mode in CRS Bits++/#/Display++ is now using full dynamic range (previously 8bit blue gun overlay was overriding the 16bit screen buffer)

New in PsychoPy 1.82.01 (Mar 14, 2015)

  • FIXED: problem with MovieStim2 showing black box instead of movie on certain systems
  • FIXED: problem with Tobii eye tracker not closing calibration window (Sol)
  • FIXED: better timing for non-slip routines that follow dynamic routines (Jeremy) #822
  • FIXED: problem with stimuli (e.g. shapes) not appearing if a texture had just been created and not yet drawn
  • FIXED: pygame sound engine complained about “global variable loops not defined”
  • ENHANCED: Filename collision handling for ExperimentHandler (Richard Höchenberger)
  • CHANGED: for text data outputs that give delim=’t’ the file extension ‘.tsv’ is added instead of ‘.dlm’ (Richard Höchenberger)

New in PsychoPy 1.78.01 (Aug 23, 2013)

  • FIXED: Image Components were showing up a pastel versions when no actual image was provided
  • FIXED: MultiStairHandler wasn’t working on Builder, and had insufficient data outputs when using wide-text csv files
  • FIXED: loops couldn’t be deleted from the Flow if their conditions file couldn’t be found (e.g. had been moved)
  • FIXED: setting of color values was not honouring the autolog setting (was always logging)
  • FIXED: gui choice boxes now handle unicode in their options as well as ASCII strings (thanks Anne Peschel)
  • FIXED: Scaling bug for SMI eye-tracker in binocular mode (thanks Sol)
  • FIXED: Builder Code Components that were showing up in unreadable, single-line boxes
  • IMPROVED: All Builder Dialogs now appear close to the top of the screen (so they don’t shoot off the bottom in most screens)

New in PsychoPy 1.77.02 (Jul 15, 2013)

  • FIXED: problem with Builder Images appearing grey unless they were ‘constant’. This is a bug that was introduced in 1.77.00 with the faster loading of images.
  • FIXED: having a monitors folder with a unicode character in the path doesn’t break the app (thanks Sebastiaan Mathot)

New in PsychoPy 1.77.01 (Jun 21, 2013)

  • FIXED: The recent files list in Builder now contains recent files! (Thanks Piotr Iwaniuk)
  • FIXED: Timing issue with LC Tech eye-tracker in iohub
  • Standalone package changes:
  • pytables downgraded to 2.3.5 on Win32 (to be compatible with WinXP)
  • pyo upgraded to 0.6.6 on OSX and Win32

New in PsychoPy 1.77.00 (Jun 13, 2013)

  • ADDED: preview of Sol Simpson’s ioHub for faster (asynchronous) polling of hardware including mouse, keyboard, eyetrackers and other devices. See iohub demos for example usage. This provides many advantages over previous event polling:
  • asynchronous process allows constant polling (not tied to refresh rates) in a way that won’t impact the rendering of your stimuli. It even runs on a separate CPU core if possible.
  • provides up/down/duration for key presses
  • provides unicode character (rather than simply key name for keyboard)
  • provides a unified API for eyetracker classes
  • provides async access to the parallel port
  • provides an alternative data output format (using hdf5) particularly useful for high-output streaming data (e.g. eye-trackers)
  • DEPRECATED: opensslwrap will soon be replaced by pyFileSec, a much-improved version of the same package (= file-oriented encryption)
  • IMPROVED: substantially (~40%) faster loading of RGB images from disk (by using byte format rather than float). May also allow storing of more images on graphics card than previously
  • ADDED: AdvancedMicrophone class to add and retrieve a high-frequency tone to indicate the start of recording (e.g., to allow accurate vocal RT estimation), with demo (Jeremy Gray)
  • REFACTORED: parallel port support. Support for Windows via inpout32/inpout64 and Linux via pyparallel added. Existing API maintained for single port usage, but new PParallel classes added to provide more flexibility when dealing with multiple ports. see psychopy.parallel - functions for interacting with the parallel port (Thanks Mark Hymers)
  • ADDED: MovieStim now updates its status attribute to FINISHED, in line with other stimuli
  • CHANGED: microphone default file names include milliseconds (to avoid two files with the same name)
  • ADDED: color-word speech-recognition demo (coder > input > speech_recognition.py)
  • ADDED: in Builder components dialog boxes, text that will be interpreted as code is displayed in monospace font
  • ADDED: remove and warn about trailing whitespace in Builder component values (but not Text fields)
  • ADDED: support for pyglet version 1.2 alpha (but 1.1.4 is still recommended - it appears to render faster)
  • ADDED: more sound.SoundPyo methods (get & set duration, volume, looping)
  • FIXED: event.Mouse() can obtain a default visual.Window(), if one has already been created
  • ADDED: Builder components generate a compile-time warning if a field’s value looks dynamic but its updating is constant (Jeremy Gray)
  • ADDED: better simulated scanner-noise in launchScan (just for fun)
  • ADDED: RatingScale.getHistory() returns intermediate time-stamped ratings; allows “continuous” ratings
  • CHANGED: RatingScale.getRating() no longer returns False prior to an accepted rating (now returns the currently selected value)

New in PsychoPy 1.76.00 (Feb 21, 2013)

  • ADDED: Window.callOnFlip() function to allow arbitrary functions to be called, timed precisely to the point where the frame flip has occurred (see Coder Demos>Timing>callOnFlip)
  • FIXED: a scaling bug in RatingScale descriptions (Giuseppe Pagnoni)
  • ADDED: support for mirror-image text, and mirror-image BufferImageStim (Jeremy Gray)
  • ADDED: support for lower latency sound with the pyo library. For now pygame remains the default but this can be changed by setting the order in preferences>general>audio
  • CHANGED: PsychoPy Standalone is now being built using python 2.7.3 (rather than 2.6). Under OSX psignifit has been removed from this distribution, as have the libraries to create .mov files using Window.saveMovieFrames(). If you need those features then install the 1.75 Standalone and then update to 1.76 using the auto-update system.
  • ADDED: sound objects (either pygame or pyo) now support autologging
  • FIXED: a bug in the generation of the LMS color space conversion matrix. It seems nobody was actually using this for real, but if you were contact Jon for details!
  • FIXED: problem with unset exp.name (was causing wx.Dialog error “TypeError: String or Unicode type required” on new experiments)
  • CHANGED: exp.name is no longer available from Builder scripts (use exp.getExpName() instead)
  • FIXED: problem with tiling of depth values for ElementArrayStim (thanks Yuri Spitsyn)
  • FIXED: Fix to setContrast for certain visual stimuli (Jonas Lindeløv)
  • FIXED: inability to launch scripts/experiments if the Mac Standalone was in a folder with a space in it
  • FIXED: Aperture Component now honours the ‘units’ (Hiroyuki Sogo)
  • FIXED: stimulus contains/overlaps functions now use stimulus ‘units’ and take stimulus orientation into account (Hiroyuki Sogo) NB if you had code in place to perform these corrections yourself you should now remove it!
  • FIXED: some data outputs were not honouring the ‘matrixOnly’ option (Mike MacAskill)
  • FIXED: when loading a psydat file of an ExperimentHandler the file automatically saved new copies of its csv/excel outputs. This no longer occurs (if loaded using misc.fromFile)
  • ADDED: timestamp option to event.waitKeys() (Jonas Lindeløv)
  • ADDED: a first-run wizard to check the system, report as html (somewhat experimental) (Jeremy Gray)
  • ADDED: a benchmark wizard (Tools menu) to test hardware & software, option to share on psychopy.org (Jeremy Gray)
  • ADDED: info.getRAM() (Jeremy Gray)
  • FIXED: Fall back to primary display if a secondary one is specified but unavailable. (Erik Kastman)
  • CHANGED: various changes to RatingScale (thanks Henrik Singman):
  • CHANGED: choices are now displayed at the tick marks by default (instead of above the line). To restore the old behavior set labels=False. This does not affect experiments created in older versions of the builder.
  • ADDED: check box “choiceLabelsAboveLines” to the RatingScale component of the builder (advanced tab) to still have the choice labels above the line.
  • ADDED: arguments tickMarks and labels to RatingScale class to control where tick marks (for quantitative rating scales) should be placed at the line and how these should be labeled.
  • ADDED: argument ticksAboveLine to RatingScale class. Controls where the tick marks should be plotted (above or below the line).

New in PsychoPy 1.75.01 (Oct 2, 2012)

  • FIXED: Bug with not being able to play sounds of blank (infinite) duration from Builder

New in PsychoPy 1.74.03 (Aug 14, 2012)

  • FIXED: the multiline text entry box in the Builder Text Component was broken (thanks Piotr Iwaniuk)
  • IMPROVED: serial (RS232) interface to fORP button box to avoid recording repeated presses (thanks Nate Vack). Does not affect use of fORP box from USB interface.

New in PsychoPy 1.74.02 (Aug 6, 2012)

  • FIXED: bug leading to message: IndexError: string index out of range. This was caused by problem saving excel files
  • FIXED: bug leading to message: AttributeError: ImageStim instance has no attribute ‘rgbPedestal’. Was only occurring on non-shaders machines using the new ImageStim.
  • FIXED: problem loading old ExperimentHandlers that contained MultiStairHandlers
  • FIXED: Builder Text Components gave an error if letter height was a variable
  • ADDED: Window.flip() now returns the timestamp for the flip if possible (thanks (Sol Simpson)
  • ADDED: misc.sph2cart (Becky Sharman)
  • ADDED: warning when user presents SimpleImageStim that seems to extend beyond screen (James McMurray)

New in PsychoPy 1.74.00 (Jul 11, 2012)

  • Highlights (and compatibility changes):
  • CHANGED: Builder experiments saved from this version will NOT open in older versions
  • ADDED: ‘non-slip’ timing methods to the Builder interface (improved timing for imaging experiments) See Non-slip timing for imaging for further info
  • ADDED: Long-wide data file outputs, which are now the default for all new Builder experiments. See Long-wide data file outputs
  • ADDED: basic audio capture (and speech recognition via google!). Builder now has a Microphone Component to record inputs, but does not yet use the speech recognition facility. See psychopy.microphone library, Coder demo “input/say_rgb.py” and Builder demo “voiceCapture”. (Jeremy)
  • ADDED: HSV color space for all stimuli
  • CHANGED: in Builder the default dotstim has signal dots=’same’ (once a signal dot, always a signal dot). Only affects new experiments.
  • CHANGED: The summarised excel/csv outputs now have an additional column for the order of the stimulus as presented. This may affect any automated analysis you perform on your spreadsheet outputs.
  • CHANGED: data.FitCumNormal now uses a slightly different equation that has a slightly different equation, which alters the interpretation of the parameters (but not the quality of fit). Parameters from this function before version 1.74 cannot to be compared with new values.
  • CHANGED: pygame is no longer being formally supported/tested although it will probably continue to work for some time.
  • RESTRUCTURED: the generation of ‘summarised’ data outputs (text and excel) were also rewritten in this versino, so make sure that your data files still contain all the data you were expecting
  • Additional changes:
  • FIXED: missing parameter name in conditions file is detected, triggers more informative error message
  • ADDED: fORP: option asKeys to handle button presses as pyglet keyboard events (when using a serial port); faster getUniqueEvents()
  • ADDED: basic file encryption (beta) using RSA + AES-256; see API encryption for usage and caveats
  • ADDED: upload a file to a remote server over http (libs: web.upload) with coder demo, php scripts for server (contrib/http/*)
  • ADDED: Builder demo (dualRatingScales): show a stim, get two different ratings side by side [unpack the demos again]
  • ADDED: rating scale options: ‘maxTime’ to time-out, ‘disappear’ to hide after a rating; see new Builder demo
  • FIXED: rating scale bug: skipKeys was not handling ‘tab’ properly (no skip for tab-key, do skip for ‘t’, ‘a’, or ‘b’)
  • ADDED: new locale pref for explicitly setting locale, used in date format and passed to builder scripts (Jeremy, Hiroku Sogo)
  • ADDED: ‘enable escape’ option in experiment settings, default is ‘enabled’
  • ADDED: support for ElementArrayStim to use the same set of color spaces as other stimuli
  • CHANGED: removed python 2.4’s version of sha1 digest from RunTimeInfo
  • CHANGED: removed any need for PyOpenGL (pyglet.gl now used throughout even for pygame windows)
  • FIXED: Builder was ignoring changes to DotStim FieldPos (thanks Mike MacAskill)
  • FIXED: Builder Flow is smarter about Loops and now stops you creating ‘broken’ ones (e.g. Loops around nothing)
  • FIXED: MovieStim used from Builder was not working very well. Sounds continued when it was told to stop and the seek(0.0001) line was causing some file formats not to work from Builder only (those that don’t support seeking)
  • FIXED: Mouse component was not saving clicks in Builder experiments if forceEndOnClick was set to be False
  • FIXED: DotStim.setFieldCoherence was having no effect if noise dots were updating by ‘position’
  • FIXED: TextStim.setColor() was not updating stimulus properly when haveShaders=False
  • FIXED: In Builder, sound duration was not being used in creating new sounds
  • CHANGED: Under linux, although you will be warned if a new version is available, it will not be auto-installed by PsychoPy (that should be done by your package manager)
  • FIXED: csv/dlm data outputs no longer have a trailing delimitter at end of line
  • FIXED: all test suite tests should now pass :-)

New in PsychoPy 1.70.00 (Aug 24, 2011)

  • CHANGED use of allowedKeys in Keyboard Component. You used to be able to type ynq to get those keys, but this was confusing when you then needed ‘space’ or ‘left’ etc. Now you must type ‘y’,’n’,’q’, which makes it more obvious how to include ‘space’,’left’,’right’...
  • CHANGED dot algorithm in DotStim. Previously the signalDots=same/different was using the opposite to Scase et al’s terminology, now they match. Also the default method for noiseDots was ‘position’ and this has been changed to ‘direction’. The documentation explaining the algorithms has been clarified. (see Dots (RDK) Component)
  • CHANGED MovieStim.playing property to be called MovisStim.status (in keeping with other stimuli)
  • CHANGED names:
  • data.importTrialTypes is now data.importConditions
  • forceEndTrial in Keyboard Component is now forceEndRoutine
  • forceEndTrialOnPress in Mouse Component is now forceEndRoutineOnPress
  • trialList and trialListFile in Builder are now conditions and conditionsFile, respectively
  • ‘window units’ to set Component units is now ‘from exp settings’ for less confusion
  • CHANGED numpy imports in Builder scripts:
  • only a subset of numpy features are now imported by default: numpy: sin, cos, tan, log, log10, pi, average, sqrt, std, deg2rad, rad2deg, linspace, asarray, random, randint, normal, shuffle
  • all items in the numpy namespace are available as np.*
  • if a pre-v1.70 script breaks due to this change, try prepending ‘np.’ or ‘np.random.’
  • CHANGED Builder use of $. $ can now appear anywhere in the field (previously only the start). To display a ‘$’ character now requires ‘\$’ in a text field (to prevent interpretation of normal text as being code).
  • ADDED flexibility for start/stop in Builder Components. Can now specify stimuli according to:
  • variable values (using $ symbol). You can also specify an ‘expected’ time/duration so that something is still drawn on the timeline
  • number of frames, rather than time (s), for greater precision
  • an arbitrary condition (e.g. otherStim.status==STOPPED )
  • ADDED the option to use a raised cosine as a PatchStim mask (thanks Ariel Rokem)
  • ADDED a preference setting for adding custom path locations to Standalone PsychoPy
  • ADDED Dots Component to Builder interface for random dot kinematograms
  • ADDED wide-format data files (saveAsWideText()) (thanks Michael MacAskill)
  • ADDED option for full randomization of repeated lists (loop type ‘fullRandom’) (Jeremy)
  • ADDED builder icons can now be small or large (in prefs)
  • ADDED checking of conditions files for parameter name conflicts (thanks Jeremy)
  • ADDED emulate sync pulses and user key presses for fMRI or other scanners (for testing); see hardware/launchScan in the API reference, and Coder demos > experimental control > fMRI_launchScan.py (Jeremy)
  • ADDED right-clicking the expInfo in Experiment Settings tests & previews the dialog box (Jeremy)
  • ADDED syntax checking in code component dialog, right-click (Jeremy)
  • IMPROVED documentation (thanks Becky Sharman)
  • IMPROVED syntax for using $ in code snippets (e.g., “[$xPos, $yPos]” works) (Jeremy)
  • IMPROVED Flow and Routine displays in the Builder, with zooming; see the View menu for key-board shortcuts (Jeremy)
  • IMPROVED Neater (and slightly faster) changing of Builder Routines on file open/close
  • FIXED demos now unpack to an empty folder (Jeremy)
  • FIXED deleting an empty loop from the flow now works (Jeremy)
  • FIXED further issue in QUEST (the addition in 1.65.01 was being used too widely)
  • FIXED bug with updating of gamma grid values in Monitor Center

New in PsychoPy 1.65.00 (Jul 4, 2011)

  • ADDED improved gamma correction using L=a+(b+kI)**G formula (in addition to industry-standard form). Existing gamma calibrations will continue to use old equation but new calibrations will take the new extended formula by default.
  • ADDED MultiStairHandler to run multiple interleaved staircases (also from the Builder)
  • ADDED createFactorialTrialList, a convenience function for full factorial conditions (thanks Marco Bertamini)
  • CHANGED Builder keyboard components now have the option to discard previous keys (on by default)
  • CHANGED RatingScale:
  • ADDED: argument to set lineColor independently (thanks Jeff Bye)
  • CHANGED default marker is triangle (affects windows only)
  • ADDED single-click option, custom-marker support
  • FIXED: bug with precision=1 plus auto-rescaling going in steps of 10 (not 1)
  • FIXED errors with importing from ‘ext’ and ‘contrib’
  • FIXED error in joystick demos
  • FIXED bug in ElementArrayStim depth
  • FIXED bug in misc.maskMatrix. Was not using correct scale (0:1) for the mask stage
  • FIXED buglet in StairHandler, which was only terminating during a reversal
  • FIXED bug when loading movies - they should implicitly pause until first draw() (thanks Giovanni Ottoboni)
  • IMPROVED handling of non-responses in Builder experiments, and this can now be the correct answer too (corrAns=None). ie. can now do go/no-go experiments. (Non-responses are now empty cells in excel file, not “–” as before.)

New in PsychoPy 1.63.00 (Dec 27, 2010)

  • FIXED bug in color calibration for LMS color space (anyone using this space should recalibrate immediately) Thanks Christian Garber for picking up on this one.

  • FIXED bug with ShapeStim initialisation (since 1.62.02)
  • UPDATED: Builder demos
  • ADDED autoLog mechanism:
  • many more messages sent, but only written when log.flush() is called
  • rewritten backend to logging functions to remove file-writing performance hit
  • added autoLog and name attributes to visual stimuli
  • added setAutoDraw() method to visual stimuli (draws on every win.flip() until set to False)
  • added logNextFlip() method to visual.Window to send a log message time-stamped to flip
  • UPDATED: Standalone distribution now uses Python2.6 and adds/upgrades;
  • parallel python (pp)
  • pyserial
  • ioLabs toolbox
  • ipython (for future ipython shell view in coder)
  • numpy=1.5.1, scipy=0.8.0, matplotlib=1.0
  • labjack toolbox

New in PsychoPy 1.61.02 (Jun 21, 2010)

  • ADDED: Code Component to Builder (to insert arbitrary python code into experiments)
  • ADDED: visual.RatingScale ‘stimulus’ (thanks to JG). See ratingScale demo in Coder view
  • FIXED: TrialHandler can now have dataTypes that contain underscores (thanks fuchs for the fix)
  • FIXED: loading of scripts by coder on windows assumed ASCII so broke with unicode characters. Now assumes unicode (as was case with other platforms)

  • FIXED: broken link for >Help>Api (reference) menuitem

New in PsychoPy 1.61.00 (May 15, 2010)

  • CHANGED: color handling substantially. Now supply color and colorSpace arguments and use setColor rather than setRGB etc. Previous methods still work but give deprecation warning.
  • ADDED: Colors can now also be specified by name (one of the X11 or web colors, e.g. ‘DarkSalmon’) or hex color spec (e.g. ‘#E9967A’)
