several different labs around the world attempted to replicate a classic study on the facial feedback hypothesis (strack et al., 1988). the idea is that people would find cartoons funnier when holding a pen between their teeth, mimicking a smile, than when holding a pen between their mouth, mimicking a pout. the results across the 17 labs revealed that the 95% ci included zero. which of the following statements are possible explanations for these results?

The idea is that people would find cartoons funnier when holding a pen between their teeth, mimicking a smile, than when holding a pen between their mouth, mimicking a pout. The results across the 17 labs revealed that the 95% CI included zero.

Which of the following statements are possible explanations for these results?

- the replication studies were conducted in a different setting that affected the results
- the sample size in the original study was too large, which affected the replicability of results
- the replication studies were direct replications rather than conceptual replications
- the original study may have engaged in practices that led to fluke results

The correct explanation is

- the replication studies were conducted in a different setting that affected the results

- the original study may have engaged in practices that led to fluke results
