The most interesting finding was the success of training older adults on emotion recognition, with significant improvements in accuracy. Results showed that although the training was effective at improving the recognition of valid cues to deception, the facial group’s performance was worse after training on facial cues, but the control group’s accuracy increased from pre-test to post-test. This study involved the training of two groups of older adults on valid cues to deception: one group on valid verbal cues and one group on valid facial cues. In addition, older adults are less able than young adults to accurately identify emotional facial expressions, and this hampers their ability to detect deception (e.g., shame, fear, and “duping delight”). One reason for poor deceit detection abilities is that lay theories of cues to deception are not valid. Older adults are worse than young adults at detecting deception, which may a play a role in the increasing occurrence of financial exploitation of the elderly. Older adults showed the most benefit from sheer practice at detecting deception (in the control condition), perhaps because this condition encouraged implicit rather than explicit judgments of deception. Older adults’ facial and verbal cue recognition can be improved with training, but these improvements did not translate into more accurate deceit detection, and actually hampered performance in the facial condition. These results are consistent with the body of literature on deception suggesting people hover around chance accuracy, even after training.

However, the facial cue training group were less accurate at detecting deception post-test compared to pre-test and the control group exhibited improved accuracy of deceit detection from pre-test to post-test. Resultsīoth training groups significantly improved at recognizing their respectively trained cues after training. Participants completed a pre-test deceit detection task, their assigned training, and a post-test deceit detection task. Approximately 150 older adults were randomly assigned to facial training, verbal training, or a control condition. This study compared the effectiveness of two training methods to improve deceit detection among older adults: valid facial cues versus valid verbal cues to deception. Older adults are even worse than young adults at detecting deceit, which might make them uniquely vulnerable to certain types of financial fraud. In general, people are poor at detecting deception.
