Deception Detection and Truth Detection Are Dependent on Different Cognitive and Emotional Traits: An Investigation of Emotional Intelligence, Theory of Mind, and AttentionDespite evidence that variation exists between individuals in high-stakes truth and deception detection accuracy rates, little work has investigated what differences in individuals’ cognitive and emotional abilities contribute to this variation. Our study addressed this question by examining the role played by cognitive and affective theory of mind (ToM), emotional intelligence (EI), and various aspects of attention (alerting, orienting, executive control) in explaining variation in accuracy rates among 115 individuals [87 women; mean age = 27.04 years (SD = 11.32)] who responded to video clips of truth-tellers and liars in real-world, high-stakes contexts. Faster attentional alerting supported truth detection, and better cognitive ToM and perception of emotion (an aspect of EI) supported deception detection. This evidence indicates that truth and deception detection are distinct constructs supported by different abilities. Future research may address whether interventions targeting these cognitive and emotional traits can also contribute to improving detection skill.
Enhanced threat detection in experienced riot police officers: Cognitive evidence from the face-in-the-crowd effectWe explored how varying levels of professional expertise in hostile crowd management could enhance threat detection capabilities as assessed by the face in the crowd paradigm. Trainee police officers and more experienced police officers specialized in, and having extensive experience with, riot control, were compared with participants with no experience in hostile crowd management on their search times and accuracy levels in detecting angry and happy face targets against a display of emotional and neutral dis- tractor faces. The experienced officers relative to their trainee counterparts and nonpolice controls showed enhanced detection for threatening faces in both types of display along with a greater degree of inhibitory control over angry face distractors. These findings help to reinforce the ecological validity of the face in the crowd paradigm and provide a new theoretical link for the role of individual differences on the attentional processing of socially relevant stimuli.
Right-lateralized unconscious, but not conscious, processing of affective environmental soundsMuch research on the laterality of affective auditory stimuli features emotional speech. However, environmental sounds can also carry affective information, but their lateralized processing for affect has been studied much less. We studied this in 2 experiments. In Experiment 1 we explored whether the detection of affective environmental sounds (from International Affective Digital Sounds) that appeared in auditory scenes was lateralized. While we found that negative targets were detected more rapidly, detection latencies were the same on the left and right. In Experiment 2 we examined whether conscious appraisal of the stimulus was needed for lateralization patterns to emerge, and asked participants to rate the stimuli's pleasantness in a dichotic listening test. This showed that when positive/negative environmental sounds were in the attended to-be-rated channel, ratings were the same regardless of laterality. However, when participants rated neutral stimuli and the unattended channel was positive/negative, the valence of the unattended channel affected the neutral ratings more strongly with left ear (right hemisphere, RH) processing of the affective sound. We link our findings to previous work that suggests that the RH may specialize in the unconscious processing of emotion via subcortical routes.
