Metric Options: Counts1 Year3 YearSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
Objective There have, as yet, been few experimental studies of explicit facial affect recognition in patients with dissociative seizures (DS). The aim of the study was to examine explicit recognition and physiological responses to facial expressions in this group, relative to healthy controls. Methods Forty patients with DS and 43 controls completed a computerized test of facial affect recognition, including five basic expressions (happiness, anger, disgust, fear, neutral). Recognition accuracy, emotional intensity judgements, and skin conductance levels and responses were dependent measures. Analyses controlled for a range of potentially confounding variables, including anxiety, depression, and medication effects. Results The DS group was less accurate at identifying facial expressions than controls (p =.005, η 2 p = 0.10). No group difference emerged for intensity judgements (p =.72, η 2 p = 0.002). Mean skin conductance levels were higher in the DS group relative to controls (p =.046, η 2 p = 0.053). However, a subgroup of DS patients showed attenuated skin conductance responses to the facial stimuli, compared with controls (p =.015, η 2 p = 0.18). These differences could not be accounted for by possible confounding variables. Recognition accuracy for neutral faces correlated negatively with trauma scores (r = -0.486, p =.002) and abandonment concerns (r = -0.493, p =.002) in the DS group. Conclusions Patients with DS showed reduced recognition accuracy for facial affect, despite accurately perceiving its intensity. Elevated autonomic arousal may characterize patients with DS in general, alongside reduced phasic autonomic responses to facial expressions in some patients with the disorder.
