Intranasal Oxytocin and Response Inhibition in Young and Older Adults
- 2017
-
Konferensbidrag (refereegranskat)abstract
- In normal aging, people are confronted with impairment in both socioemotional and cognitive abilities. Specifically, there are age-related declines in inhibitory processes that regulate attention towards irrelevant material. In last years, the intranasal administration of the neuropeptide oxytocin has mainly been related to improvements in several domains such as emotion recognition and memory, but to date the effects of oxytocin in aging remain largely unknown. In a randomized, double blind, placebo controlled, within-subjects study design, we investigated whether oxytocin facilitates inhibitory processing in older adults compared to younger adults. In total, 41 older adults (51% women; age range 65-75 years) and 37 younger adults (49% women; age range 20-30 years) participated in this study two times, receiving a single intranasal dose of 40 IU of placebo and oxytocin in randomized order 45 minutes before engaging in the task. Participants were tested approximately a month apart and mostly at the same hour during both occasions. Inhibition was measured with a Go/NoGo task which included happy and neutral faces as targets (Go stimuli) and distractors (NoGo stimuli) shown on a computer screen. Participants were instructed to press a button any time they saw a target and remain passive when encountering a distractor. Preliminary results indicate effects for happy and neutral faces, but only in the distractor condition. For happy distractors, women rejected correctly happy faces more accurately than men did, both in the placebo and oxytocin conditions. A main effect of age was observed for the neutral distractors, where older adults were more successful in inhibiting responses than younger adults during oxytocin and placebo treatments. We did not observe effects of oxytocin in the different tasks. The role of oxytocin was not clear distinguished in the tasks. In sum, our findings showed that age and gender can influence inhibition but their effects depend on the displayed emotions. This suggests that the ability to inhibit interfering distractors may remain intact despite of age and that deficits in inhibition may be selective. The role of oxytocin in inhibition needs to be further investigated since it is possible that it is context dependent.

Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- Background: Computerized trainings for emotion recognition accuracy (ERA) have shown to be successful, however, are often lacking external validity. The use of still pictures, the focus on the face, and limited response sets limit generalizability of findings. Further, trainings often use between-subjectsdesigns and short time intervals between, or same items for ERA training and outcome measure. In response, we developed and evaluated a multi-modal ERA training in a randomized controlled trial.Method: Seventy-two undergraduate students (M=24.7, SD=7.69, 75% women) signed up for the study; 68 completed all measurements. They were randomly assigned to the multimodal ERA training or one of two control conditions. The ERA outcome measure (ERAM; Laukka et al., 2015) assesses 12 emotions separately in three modalities (audio, video, audio-video) using 72 dynamic stimuli. The multimodal training consisted and immediate and extensive feedback using different items. The last training session and the ERA outcome measurement lay approximately one week apart.Results and Conclusions: A repeated-measures ANOVA with baseline as covariate showed a main effect of training on the ERAM, F(2/63) = 8.04, p < .001, ηp2 = .20. Bonferroni-corrected posthoc tests revealed the change for the multimodal training was significantly superior to the control conditions (p=.001; p=.003). Detailed results per modality and descriptive statistics will be presented. Due to its multimodal and dynamic nature, delay between training and outcome measure and use of different items, the multimodal training is a promising tool for training ERA in different contexts, like clinical settings, assessment procedures or law enforcement training.

Tidskriftsartikel (refereegranskat)abstract
- The ability to recognize and work with patients’ emotions is considered an important part of most psychotherapy approaches. Surprisingly, there is little systematic research on psychotherapists' ability to recognize other people’s emotional expressions. In this study, we compared trainee psychotherapists’ non-verbal emotion recognition accuracy to a control group of undergraduate students at two time points: at the beginning and at the end of one and a half years of theoretical and practical psychotherapy training. Emotion recognition accuracy (ERA) was assessed using two standardized computer tasks, one for recognition of dynamic multimodal (facial, bodily, vocal) expressions and one for recognition of facial micro expressions. Initially, 154 participants enrolled in the study, 72 also took part in the follow-up. The trainee psychotherapists were moderately better at recognizing multimodal expressions, and slightly better at recognizing facial micro expressions, than the control group at the first test occasion. However, mixed multilevel modeling indicated that the ERA change trajectories for the two groups differed significantly. While the control group improved in their ability to recognize multimodal emotional expressions from pretest to follow-up, the trainee psychotherapists did not. Both groups improved their micro expression recognition accuracy, but the slope for the control group was significantly steeper than the trainee psychotherapists’. These results suggest that psychotherapy education and clinical training do not always contribute to improved emotion recognition accuracy beyond what could be expected due to time or other factors. Possible reasons for that finding as well as implications for the psychotherapy education are discussed.

- Introduction: Psychotherapists’ emotional and empathic competencies have a positive influence on psychotherapy outcome and alliance. However, it is doubtful whether psychotherapy education in itself leads to improvements in trainee psychotherapists’ emotion recognition accuracy (ERA), which is an essential part of these competencies.Methods: In a randomized, controlled, double-blind study (N = 68), we trained trainee psychotherapists (57% psychodynamic therapy and 43% cognitive behavioral therapy) to detect non-verbal emotional expressions in others using standardized computerized trainings – one for multimodal emotion recognition accuracy and one for micro expression recognition accuracy – and compared their results to an active control group one week after the training (n = 60) and at the one-year follow up (n = 55). The participants trained once weekly during a three-week period. As outcome measures, we used a multimodal emotion recognition accuracy task, a micro expression recognition accuracy task and an emotion recognition accuracy task for verbal and non-verbal (combined) emotional expressions in medical settings.Results: The results of mixed multilevel analyses suggest that the multimodal emotion recognition accuracy training led to significantly steeper increases than the other two conditions from pretest to the posttest one week after the last training session. When comparing the pretest to follow-up differences in slopes, the superiority of the multimodal training group was still detectable in the unimodal audio modality and the unimodal video modality (in comparison to the control training group), but not when considering the multimodal audio-video modality or the total score of the multimodal emotion recognition accuracy measure. The micro expression training group showed a significantly steeper change trajectory from pretest to posttest compared to the control training group, but not compared to the multimodal training group. However, the effect vanished again until the one-year follow-up. There were no differences in change trajectories for the outcome measure about emotion recognition accuracy in medical settings.Discussion: We conclude that trainee psychotherapists’ emotion recognition accuracy can be effectively trained, especially multimodal emotion recognition accuracy, and suggest that the changes in unimodal emotion recognition accuracy (audio-only and video-only) are long-lasting. Implications of these findings for the psychotherapy education are discussed.

Tidskriftsartikel (refereegranskat)abstract
- Nonverbal emotion recognition accuracy (ERA) is a central feature of successful communication and interaction, and is of importance for many professions. We developed and evaluated two ERA training programs—one focusing on dynamic multimodal expressions (audio, video, audio-video) and one focusing on facial micro expressions. Sixty-seven subjects were randomized to one of two experimental groups (multimodal, micro expression) or an active control group (emotional working memory task). Participants trained once weekly with a brief computerized training program for three consecutive weeks. Pre-post outcome measures consisted of a multimodal ERA task, a micro expression recognition task, and a task about patients' emotional cues. Post measurement took place approximately a week after the last training session. Non-parametric mixed analyses of variance using the Aligned Rank Transform were used to evaluate the effectiveness of the training programs. Results showed that multimodal training was significantly more effective in improving multimodal ERA compared to micro expression training or the control training; and the micro expression training was significantly more effective in improving micro expression ERA compared to the other two training conditions. Both pre-post effects can be interpreted as large. No group differences were found for the outcome measure about recognizing patients' emotion cues. There were no transfer effects of the training programs, meaning that participants only improved significantly for the specific facet of ERA that they had trained on. Further, low baseline ERA was associated with larger ERA improvements. Results are discussed with regard to methodological and conceptual aspects, and practical implications and future directions are explored.

Viewing distance matter to perceived intensity of facial expressions
- 2015

Ingår i: Frontiers in Psychology. - : Frontiers Media SA. - 1664-1078. ; 6

Tidskriftsartikel (refereegranskat)abstract
- In our daily perception of facial expressions, we depend on an ability to generalize across the varied distances at which they may appear. This is important to how we interpret the quality and the intensity of the expression. Previous research has not investigated whether this so called perceptual constancy also applies to the experienced intensity of facial expressions. Using a psychophysical measure (Borg CR100 scale) the present study aimed to further investigate perceptual constancy of happy and angry facial expressions at varied sizes, which is a proxy for varying viewing distances. Seventy-one (42 females) participants rated the intensity and valence of facial expressions varying in distance and intensity. The results demonstrated that the perceived intensity (PI) of the emotional facial expression was dependent on the distance of the face and the person perceiving it. An interaction effect was noted, indicating that close-up faces are perceived as more intense than faces at a distance and that this effect is stronger the more intense the facial expression truly is. The present study raises considerations regarding constancy of the PI of happy and angry facial expressions at varied distances.

- Flow is the subjective experience of effortless attention, reduced self-awareness, and enjoyment that typically occurs during optimal task performance. Previous studies have suggested that flow may be associated with a non-reciprocal coactivation of the sympathetic and parasympathetic systems and, on a cortical level, with a state of hypofrontality and implicit processing. Here, we test these hypotheses, using the computer game TETRIS as model task. The participants (n = 77) played TETRIS under three conditions that differed in difficulty (Easy < Optimal < Difficult). Cardiac and respiratory activities, and the average oxygenation changes of the prefrontal cortex were measured continuously with functional near infrared spectroscopy (INIRS) during performance. The Optimal condition was characterized by the highest levels of state flow, positive affect, and effortless attention. The associations between self-reported psychological flow and physiological measures were investigated using a series of repeated measures linear mixed model analyses. The results showed that higher flow was associated with larger respiratory depth and lower LF. The higher respiratory depth during high flow is indicative of a more relaxed state with an increased parasympathetic activity, and thus provides partial support for the main hypotheses. There was no association between frontal cortical oxygenation and flow, even at liberal thresholds; i.e. we found no support that flow is related to a state of hypofrontality.

Cognition, prior aggression, and psychopathic traits in relation to impaired multimodal emotion recognition in psychotic spectrum disorders
- 2023

Tidskriftsartikel (refereegranskat)abstract
- Background: Psychopathic traits have been associated with impaired emotion recognition in criminal, clinical and community samples. A recent study however, suggested that cognitive impairment reduced the relationship between psychopathy and emotion recognition. We therefore investigated if reasoning ability and psychomotor speed were impacting emotion recognition in individuals with psychotic spectrum disorders (PSD) with and without a history of aggression, as well as in healthy individuals, more than self-rated psychopathy ratings on the Triarchic Psychopathy Measure (TriPM). Methods: Eighty individuals with PSD (schizophrenia, schizoaffective disorder, delusional disorder, other psychoses, psychotic bipolar disorder) and documented history of aggression (PSD+Agg) were compared with 54 individuals with PSD without prior aggression (PSD-Agg) and with 86 healthy individuals on the Emotion Recognition Assessment in Multiple Modalities (ERAM test). Individuals were psychiatrically stable and in remission from possible substance use disorders. Scaled scores on matrix reasoning, averages of dominant hand psychomotor speed and self-rated TriPM scores were obtained. Results: Associations existed between low reasoning ability, low psychomotor speed, patient status and prior aggression with total accuracy on the ERAM test. PSD groups performed worse than the healthy group. Whole group correlations between total and subscale scores of TriPM to ERAM were found, but no associations with TriPM scores within each group or in general linear models when accounting for reasoning ability, psychomotor speed, understanding of emotion words and prior aggression. Conclusion: Self-rated psychopathy was not independently linked to emotion recognition in PSD groups when considering prior aggression, patient status, reasoning ability, psychomotor speed and emotion word understanding.
