Remediation of facial emotion perception in schizophrenia: concomitant changes in visual attention.
ABSTRACT The study examined changes in visual attention in schizophrenia following training with a social-cognitive remediation package designed to improve facial emotion recognition (the Micro-Expression Training Tool; METT). Forty out-patients with schizophrenia were randomly allocated to active training (METT; n=26), or repeated exposure (RE; n=14); all completed an emotion recognition task with concurrent eye movement recording. Emotion recognition accuracy was significantly improved in the METT group, and this effect was maintained after one week. Immediately following training, the METT group directed more eye movements within feature areas of faces (i.e., eyes, nose, mouth) compared to the RE group. The number of fixations directed to feature areas of faces was positively associated with emotion recognition accuracy prior to training. After one week, the differences between METT and RE groups in viewing feature areas of faces were reduced to trends. However, within group analyses of the METT group revealed significantly increased number of fixations to, and dwell time within, feature areas following training which were maintained after one week. These results provide the first evidence that improvements in emotion recognition following METT training are associated with changes in visual attention to the feature areas of emotional faces. These findings support the contribution of visual attention abnormalities to emotion recognition impairment in schizophrenia, and suggest that one mechanism for improving emotion recognition involves re-directing visual attention to relevant features of emotional faces.

ABSTRACT: The purpose of this article was to conduct a review of the types of training offered to people with schizophrenia in order to help them develop strategies to cope with or compensate for neurocognitive or sociocognitive deficits.BMC Psychiatry 05/2014; 14(1):139. · 2.23 Impact Factor

ABSTRACT: The ability to detect micro expressions is an important skill for understanding a person’s true emotional state, however, these quick expressions are often difficult to detect. This is the first study to examine the effects of boundary factors such as training format, exposure, motivation, and reinforcement on the detection of micro expressions of emotion. A 3 (training type) by 3 (reinforcement) fixed factor design with three control groups was conducted, in which 306 participants were trained and evaluated immediately after exposure and at 3 and 6 weeks post-training. Training improved the recognition of micro expressions and the greatest success was found when a knowledgeable instructor facilitated the training and employed diverse training techniques such as description, practice and feedback (d’s[.30). Recommendations are offered for future training of micro expressions, which can be used in security, health, business, and intercultural contexts.Motivation and Emotion 01/2012; 36:371-381. · 1.55 Impact Factor

ABSTRACT: We sought to investigate the altered brain responses to emotional stimuli in patients with schizophrenia. We analyzed data from 14 patients with schizophrenia and 14 healthy controls who performed an emotional face matching task. We evaluated brain activity and connectivity in the amygdala and cortical regions during the initial (first 21 seconds of each stimulation block) and sustained (last 21 seconds) stages of an emotional processing task, and we determined changes in amygdala activity across the emotional processing task. The patients with schizophrenia showed similar amygdala activation to the controls during the initial stage of processing, but their activation decreased during the sustained stage. The controls showed increasing amygdala activity across the emotional blocks, whereas activity progressively decreased in the schizophrenia group. The patients with schizophrenia showed increased cortical activity and interconnectivity in the medial frontal and inferior parietal cortex in the initial stage of emotional processing.There was increased activity in the superior temporal cortex and greater connectivity with the inferior parietal cortex in the sustained stage. Performance accuracy was lower in the schizophrenia group in the first part of the block, while their reaction time was longer in the latter part of the block. It was not possible to specify the moment at which the switch in amygdala response occurred. Our findings suggest that patients with schizophrenia have an initial automatic emotional response but that they need to switch to a compensatory cognitive strategy to solve the task.Journal of psychiatry & neuroscience: JPN 01/2010; 35(1):41-8. · 6.24 Impact Factor
