Resting heart rate: A physiological predicator of lie detection ability
Geoffrey Duran, Isabelle Tapiero & George Michael
Physiology & Behavior, 15 March 2018, Pages 10-15
Abstract:
This study explored a psychophysiological measure, Resting Heart Rate (RHR), as a predicator of the ability to detect lies. RHR was recorded for 1 min and followed by a deception detection task in which participants were required to judge 24 videos of people describing a real-life event (50% truthful, 50% deceptive). Multiple regression analyses showed that, among other individual characteristics, only RHR predicted the ability to distinguish truth from lies. Importantly, the prediction was negative. This result suggests that the higher the RHR, the worse the detection of lies. Since the RHR is considered to be a physiological trait indexing autonomous arousal, and since high-arousal states can lead to restricted attentional resources, we suggest that limited selection and utilization of cues due to restricted attention is the reason why higher RHR leads to poor deception detection.
Pupillometry reveals the physiological underpinnings of the aversion to holes

PeerJ, January 2018
Abstract:
An unusual, but common, aversion to images with clusters of holes is known as trypophobia. Recent research suggests that trypophobic reactions are caused by visual spectral properties also present in aversive images of evolutionary threatening animals (e.g., snakes and spiders). However, despite similar spectral properties, it remains unknown whether there is a shared emotional response to holes and threatening animals. Whereas snakes and spiders are known to elicit a fear reaction, associated with the sympathetic nervous system, anecdotal reports from self-described trypophobes suggest reactions more consistent with disgust, which is associated with activation of the parasympathetic nervous system. Here we used pupillometry in a novel attempt to uncover the distinct emotional response associated with a trypophobic response to holes. Across two experiments, images of holes elicited greater constriction compared to images of threatening animals and neutral images. Moreover, this effect held when controlling for level of arousal and accounting for the pupil grating response. This pattern of pupillary response is consistent with involvement of the parasympathetic nervous system and suggests a disgust, not a fear, response to images of holes. Although general aversion may be rooted in shared visual-spectral properties, we propose that the specific emotion is determined by cognitive appraisal of the distinct image content.
Transfer of Training from Virtual to Real Baseball Batting

Frontiers in Psychology, December 2017
Abstract:
The use of virtual environments (VE) for training perceptual-motors skills in sports continues to be a rapidly growing area. However, there is a dearth of research that has examined whether training in sports simulation transfers to the real task. In this study, the transfer of perceptual-motor skills trained in an adaptive baseball batting VE to real baseball performance was investigated. Eighty participants were assigned equally to groups undertaking adaptive hitting training in the VE, extra sessions of batting practice in the VE, extra sessions of real batting practice, and a control condition involving no additional training to the players' regular practice. Training involved two 45 min sessions per week for 6 weeks. Performance on a batting test in the VE, in an on-field test of batting, and on a pitch recognition test was measured pre- and post-training. League batting statistics in the season following training and the highest level of competition reached in the following 5 years were also analyzed. For the majority of performance measures, the adaptive VE training group showed a significantly greater improvement from pre-post training as compared to the other groups. In addition, players in this group had superior batting statistics in league play and reached higher levels of competition. Training in a VE can be used to improve real, on-field performance especially when designers take advantage of simulation to provide training methods (e.g., adaptive training) that do not simply recreate the real training situation.
Fly on the right: Lateral preferences when choosing aircraft seats

Laterality: Asymmetries of Body, Brain and Cognition, forthcoming
Abstract:
A small preference has been observed for people to choose seats on the left of aircraft when booking via an online system. Although this is consistent with pseudoneglect - the known leftward bias in perception and representation - rightward preferences have been commonly observed in seating selection tasks in other environments. Additionally, the previous research in aircraft seating was unable to dissociate a bias to one side of the screen from a bias to one side of the cabin of the aircraft. Here, we present a study in which participants were asked to select seats for a range of fictional flights. They demonstrated a preference for seats on the right of the cabin, irrespective of whether the right of the cabin appeared to either the right or the left of the screen, a preference for seats towards the front of the aircraft and a preference to favour window and aisle seats. This suggests, in contrast to previous research, that participants demonstrated a rightward lateral bias to representations of an aircraft. These results may have implications for our understanding of asymmetries in cognition as well as having potentially important practical implications for airlines.
Preference for Curvilinear Contour in Interior Architectural Spaces: Evidence From Experts and Nonexperts
Oshin Vartanian et al.
Psychology of Aesthetics, Creativity, and the Arts, forthcoming
Abstract:
Much evidence suggests that preference for curvilinear visual contour is robust. We collected data from experts (i.e., self-identified architects and designers) and nonexperts to test the hypothesis that expertise moderates one's sensitivity to curvilinear contour within architectural spaces. When assessing beauty, experts found rectilinear spaces less beautiful than curvilinear spaces, whereas contour had no effect on beauty judgments among nonexperts. In contrast, when making approach-avoidance decisions, nonexperts were more likely to opt to enter curvilinear than rectilinear spaces, whereas contour had no effect on approach-avoidance decisions among experts. These results bolster the case for the importance of contour as an important and potentially adaptive feature in architecture and design, but stress the impact of expertise on its aesthetic and motivational relevance.
Control Changes the Way We Look at the World
Wen Wen & Patrick Haggard
Journal of Cognitive Neuroscience, forthcoming
Abstract:
The feeling of control is a fundamental aspect of human experience and accompanies our voluntary actions all the time. However, it remains poorly understood how the sense of control interacts with wider perception, cognition, and behavior. This study focused on how controlling an external object influences the allocation of attention. Experiment 1 examined attention to an object that is under a different level of control from the others. Participants searched for a target among multiple distractors on screen. All the distractors were partially under the participant's control (50% control level), and the search target was either under more or less control than the distractors. The results showed that, against this background of partial control, visual attention was attracted to an object only if it was more controlled than other available objects and not if it was less controlled. Experiment 2 examined attention allocation in contexts of either perfect control or no control over most of the objects. Specifically, the distractors were under either perfect (100%) control or no (0%) control, and the search target had one of six levels of control varying from 0% to 100%. When differences in control between the distractors and the target were small, visual attention was now more strongly drawn to search targets that were less controlled than distractors, rather than more controlled, suggesting attention to objects over which one might be losing control. Experiment 3 studied the events of losing or gaining control as opposed to the states of having or not having control. ERP measures showed that P300 amplitude proportionally encoded the magnitude of both increases and decreases in degree of control. However, losing control had more marked effects on P170 and P300 than gaining an equivalent degree of control, indicating high priority for efficiently detecting failures of control. Overall, our results suggest that controlled objects preferentially attract attention in uncontrolled environments. However, once control has been registered, the brain becomes highly sensitive to subsequent loss of control. Our findings point toward careful perceptual monitoring of degree of one's own agentic control over external objects. We suggest that control has intrinsic cognitive value because perceptual systems are organized to detect it and, once it has been acquired, to maintain it.
