pqraov / creates a file that determines what and how stimuli are to be presented
presents the stimuli and records responses
creates a format for coding data (data from which items go under what condition)
transfers .dtp files to drive a & save a .rdb (raw data backup) file on drive c. (the data are added to the existing .dtp file on drive a , but the previous .rdb file on drive c will be rewritten.)
incorporates the data in a .dtp file into a .dat file and computes subject and item mean RTs and error rates in each condition.
[update output>name.out, then type filename, y, y, y]
collapses data from several .dat files into one ascii data file to be used by pqraov.
analyzes data / item file, .itm

Steps involved in Using DMASTR for psycholinguistic experimentation

dm/dmtgdmdx

use cl or any text editor use a word processor

to create a text file, .itm construct an item filesuch as Word to create

a rich text format file, .rtf

run dm for text only and run the experiment run dmdx

dmtg for graphics and save data

create a dat file for coding prepare the data1. convert .azk into .dtp

data for analysisfile and follow the dm/dmtg

procedures on the left, or

use unload, update, concat

to prepare data for statistic 2. use Excel to prepare data

analysis sets for a statistic software

use pqraov to do ANOVA analyze the datause a statistic software to
analyze the data, e.g. SPSS
