Experiment investigating the effect of training order on
category learning performance reported in
Edmunds, Wills, Milton (2017), Experiment 2.
This DAU contains stimulus image files, raw data, and analysis
scripts, all in open cross-platform formats (see the
file format notes).
PLY12longData.csv (1.1
MB) - Trial-level raw data. Column headings are as follows:
DAU: Experiment name
Participant: Participant ID (unique across entire
experiment)
Condition: Experimental condition (either EasyMed,
HardMed, or MedMed. MedMed is an incomplete condition
, N=10, not reported in the paper).)
Block: Block number
SubBlock: Values from 1 to 5 that change every 30
trials to aid with learning curve graphs
Trial: Trial number
StimulusNo: Unique ID for each stimulus (number
corresponds to numbered PNG files in PLY22stimuli.zip)
Length: The value of each stimulus on the line length
dimension (in arbitrary units)
Orientation: The value of each stimulus on the
orientation dimension (in arbitrary units)
Category: The category assignment for each stimulus
(Category A=0 and Category B=1)
Difficulty: The difficulty of that stimulus (Easy,
Med, Hard)
Response: The response the participant gave (Category
A=68, Category B=76; numbers refer to ASCII code of
response letters on keyboard i.e. 68 = key 'D', 76 = key
'K')
Correct: Whether the participant was correct or not
(0 = incorrect, 1 = correct)
RT: Reaction time in seconds
R scripts for analysis of PLY12. You will
need R, plus the
following packages that are available on
CRAN:
effsize, ggplot2, irr, rmisc
PLY12 Functions.R (6
KB) - functions required by the other scripts, below.
