Researcher Rupert Sheldrake and others have investigated people's ability to
sense whether they are being looked at.
Sheldrake's research in particular has shown a consistent
effect suggesting that people may indeed be able to detect whether or not someone
is looking at them even though they are unable to see the looking person.
This test uses a variation on the normal staring experiment in which you have to
guess, in advance, whether the computer screen will show a face staring
at you, or whether the screen will remain blank.
It is advisable to first try out the Practice trials in order to get
an idea of how the test works. When the screen shows the question mark, you should
try to anticipate whether the screen will next show staring or blank (these are equally
likely on every trial). Click the appropriate button and the screen will then be
shown. Repeat this for each trial (there will be a short delay between trials).
When you are familiar with the procedure, you can test your ability more formally
by selecting a larger number of trials.
Statistical Analysis
After all trials have been completed, you will be shown the statistical analysis
of your results. The total number (and percentage) of correct and incorrect guesses
is indicated and, if there are sufficient trials, these are analysed for statistical
significance using the z-test. Note that the Practice trials are insufficient to
permit this analysis.
The z-test shows the probability (p) of obtaining your results by chance.
If the probability is less than 1 in 20 (0.05) the results are said to be statistically
significant and may indicate some precognitive ability.
If you wish to statistically analyse the results from several tests, you should
record the number of correct and incorrect guesses on each test. You may then
analyse the combined data using our Hit-Miss Psi Test Statistical Calculator.
Choose the Open Deck procedure with a probability of hit = 1 in 2.
The total number of hits = total number of correct guesses. The total number of trials = number of correct and
incorrect guesses combined. For example if you scored 2500 correct guesses and
1800 incorrect guesses, then total trials = 4300 and total hits = 2500.
