The presence of a confounding variable should be of most concern to the researcher. The hot temperature in the lab may affect the participants' perspiration levels and could be a confounding variable that influences the results. The researcher should control for this variable by ensuring that the temperature in the lab is consistent across all sessions or by randomly assigning participants to hot and cool temperature conditions. It is possible that other confounding variables may also be present and should be identified and controlled for in order to accurately determine the relationship between telling embarrassing stories and perspiration levels.
