To start the program make certain that the file crash.exe is in
your current directory and type : crash [ENTER].
The second display page gives a brief description of the
experiment. For each run you will see a trace curving around a
row of obstacles, reminiscent of a skier slaloming around a row
of trees. When the skier hits a tree the run ends and the score
gives the number of safely negotiated trees.
From run to run, the task changes, and you are asked
to use correspondingly changing mental approaches.
In one case the program sets the goal of a high score. Here you
try to avoid crashes for as long as possible. You use a positive,
optimistic mental approach. Take a moment before the start until
you feel relaxed and confident and then press the ENTER key to
start the run. In the other case, the program asks you for a low
score, trying to hit a tree as soon as possible. In this case,
get yourself into a physically and mentally tense state and make
a "desperate" attempt to hit a tree as fast as possible. See what
happens. With many people this "negative" mental attitude leads
to the opposite of the desired outcome: particularly long rather
than short runs. Try to approach this in a somewhat detached
manner: Simply follow the instructions with regard to the
attitudes and see what happens.
In this game "Crash" the scoring is done differently from the
other games. Here the score (number of passed trees) is always
positive. The average chance value of the scores is 20, but you
will see the actual scores fluctuate widely. From the score
display table (see above) you can see your average score for the
past runs (separate for the high-aim and low-aim cases) and check
if it lies above or below 20.
If, after a larger number of completed runs, you want to
calculate the "Standard Score" as defined in the README text, you
can do it as follows:
Assume that you have completed M runs under a particular
condition (high or low aim) with the resulting scores:
Sc(1), Sc(2),...Sc(M). Then (see README file)
Standard Score =
[Sc(1)+Sc(2)+...+Sc(M)- 20 x M]/Sqr(16 x M),
where Sqr() means the square root.
