1. Description -------------- This archive contains the program packages of the English CROWN game for Singaporean children. The CROWN game is a categorical perception task for phonemes. In this English version, we use the phoneme pair /b/ and /p/. The task was narrated as a game for the child to help a little monkey to pick up flowers to make a flower crown, by finishing the task block by block. This archive includes 4 versions: **CROWN_EN_full_offline.zip** : offline version of the CROWN game with 16 tokens x 10 blocks, estimated completing time 10-12mins. **CROWN_EN_full_online.zip** : online version of the CROWN game with 16 tokens x 10 blocks, estimated completing time 10-12mins. **CROWN_EN_half_offline.zip** : offline version of the CROWN game with 8 tokens x 10 blocks, estimated completing time 5-6mins. **CROWN_EN_half_online.zip** : online version of the CROWN game with 8 tokens x 10 blocks, estimated completing time 5-6mins. All the packages archived here include the task program and all the image and audio files. The task was programmed in Opensesame. The audio stimuli includes 16 tokens(8 tokens in half versions) cut from a VOT continuum from -60ms to +90ms. The audio stimuli was recorded by local Singaporean. 2. Installation and running The offline versions of the program were developed on Opensesame 3.2 (python version 2.7). You can run them on both Opensesame 3.2 and 3.3 wit pythone 2.7. Other version of python with Opensesame has not been tested. The online versions of the program were developed with the OSWEB extention on opensesame 3.2 (python version 2.7). The packages were exported JATOS studies. See here for runnning opensesame on JATOS online: https://osdoc.cogsci.nl/3.2/manual/osweb/#jatos 3. Data A csv file will be generated automatically after the experiment. Data includes the choice made by the participant and their reaction time. R scripts is also included in the archive for extracting and generating useful variables from the raw data for further analysis. 4.
