Thinking
about upgrading to DirectRT v2004? If so, here are some of the new
features to help you decide. For an overview of
DirectRT and a summary of all
features (old and new), return to the main
DirectRT
page. If
you are ready to order or upgrade, see our
order page for
details.
There are many enhancements that come with the 2004 version of
DirectRT. For the most part all of these are optional. If you
have become accustomed to using DirectRT v2000
or v2002, you should be able
to continue without having to learn anything new.
v2004
is fully backwards compatible so that DirectRT experiments from
all previous versions should run the same as they always have
without requiring modification.
- New utility that reduces
the individual DirectRT data files (or *ANY* vertical data
files) into a single, one row per subject data file for
immediate analysis. Extremely flexible and easy to use, allowing
options to block, recode and make new variables. No more manual
data reduction!!
-
New
random number function allows for random SOAs and display
times--use it anywhere you want bounded random values in your
input file.
- Accept input from a
greater array of input devices (e.g., touch screens, light guns)
-
Option to write trial
information to the data file even when RTs are not measured.
-
Enhanced Voice RT
capability--works great now on most machines with a basic
soundcard.
- GNAT/Go-NoGo
capability--define "no response" as the correct
response--includes a new GNAT sample
-
Play video files with
extremely high precision just like any other stimulus--support
for MPEG, AVI and other video types supported by the Windows
Media Player.
-
Display animation files
with high precision start up time and screen location
- Optionally clear stimuli
from the screen while still waiting for an RT
- Optionally maintain a
fixed response time window regardless of response latency
- Assess simultaneous vocal
and manual responses
- Increased protection
against overwriting existing data
-
Data protected if session
ends early
-
Support for a greater
array of screen resolutions
-
Greater capacity, e.g.,
stimuli per trial
- Many other general tweaks
and fixes
