What were you expecting? Observer expectation effects on data recording as a result of training history

There are many biases that affect the collection of data on human behavior. One such bias is expectations. Research has shown that this bias can be reduced sometimes with training. The current study looked at how two different amounts of training time and an expectation statement affected data collection accuracy. In congruence with some previous research the current study found that those with more training were more accurate than those who had less training before the expectation statement was given, U = 1612, p = .043, r = .18. After the expectation statement was given the group that received more training was significantly more accurate than those who received less training, U = 1640, p =.058, r = .17. However, this may or may not be the result solely of the expectations effect on data collection. Reasons for these findings were discussed.
