Summary:
For this study 4 pairs of monozygotic twins (all female and between 25 and 65 years old) where tested for synchronous responses when one of the twins was exposed to shock stimuli while the second twin's body response was measured while both were in different locations.
Each test session lasted 25 minutes which were split into five 5-minute blocks. Each 5-minute block was again split into eight 30-second long trial periods with two extra 30-second pauses at the beginning and the end. Only one out of these eight slots was randomly selected for a shock stimulus application.
The five applied stimuli included placing the twins arm in a bucket with ice water, crashing porcelain plates onto the floor, the sound of bursting balloons, heat exposure and a knee reflex.
Both twins where located in 2 different rooms separated by 32,5 meters and the roles of the twins (sender/receiver) was switched after the 25-minute long experiment. The entire experiment was additionally videotaped by multiple cameras.
After the data from all twins was collected a total of 24 testing periods fulfilled the validity criteria for further analysis. An independant analyst was given the task to evaluate each of the 8 30-second periods and to select one of them as a match for showing a reaction. Due to the 1 in 8 chance 3 (24*1/8) out of the 24 periods were expected if it was a random event.
The actual results showed that 6 periods showed a match and that one of the twin pairs actually had 4 matches within their 6 periods (a highly significant result). This particular pair of twins was the youngest (25 years old), one of the twins was pregnant and they had reported previous experiences of twin telepathy in their lives - especially since one of them had become pregnant.
Conclusion (excerpt only):
The result of this experiment corresponds with a similar experiment conducted in Copenhagen where also one pair of twins showed extraordinary good results. So some identical twins show significant signs of connectedness.
