Experiment 12-follow-up.

In the Experiment 12-Follow- up the author modified the LDSR-UNIT to make the task more sensitive for short term memory fluctuations.

A second light was added above the first.

This second light is called the task reversal light.

When the task reversal light is illuminated, subject has to reverse his responses.

Instead of pressing the right button when the (bottom) light is bright, he now has to press the left button.

This way the task can not become a simple repetitive one in a relatively short time.

Turning on the task reversal light was shown on a line just above the subjects performance trace like this __—__—__

When the reversal light goes on the line goes up.

GRAPH 1 SHOWS BCG PERFORMANCE AVERAGES WITH STANDARD ERROR :
˝ HR AFTER OXYGEN INTERRUPTION  -  BEFORE OXYGEN INTERRUPTION AND  -  DURING OXYGEN INTERRUPTION  -

RIHC (see note*1)  = CORRECTED RESPONSES MINUS (INCORRECT RESPONSES) X 2   (see note*2)    CONVERTED TO "PER MINUTE" VALUES.

TRACE EXPLANATION

REGISTRATION DURING OXYGEN INTERRUPTION WAS TERMINATED WHEN SUBJECT SHOWED SUBJECTIVE SIGNS OF BECOMING
TOTALLY UNCOORDINATED .

NOTES :
*1) RIHC STANDS FOR RESERVE INFORMATION HANDLING CAPACITY (PLS. CHECK WITH YAHOO SEARCH ENGINE IF YOU
WANT ADDITIONAL INFORMATION ABOUT THIS CONSTRUCT) .
*2) THIS FORMULA WAS DEDUCTED FROM A PREVIOUS STUDY WHERE IT WAS STATISCALLY PROVEN THAT COMPARABLE PROCESSING
GAVE THE BEST RELEVANT PREDICTIONS OF DIFFERENT LEVELS OF COMPARABLE CRITERION .
