“…This is compatible with two hypotheses concerning the lateralization of emotion processing [42]: the right hemisphere hypothesis [43] and the valence hypothesis [44]. The right hemisphere hypothesis suggests that all emotional processing is lateralized to the right hemisphere, whereas the valence hypothesis suggests that positive emotion is processed in the left hemisphere, whereas negative emotions are processed in the right hemisphere.…”

Previous neuroimaging studies have suggested a role of amygdala in trait anxiety level, in which amygdala was typically treated as a whole. To date, it remains unknown whether the morphology of specific subregions of amygdala are associated with trait anxiety. Here, we employed a shape analysis approach to locate the association between its morphology and trait anxiety on the surface of amygdala. 24 healthy young participants were included. The boundary of amygdala for each subject was first manually outlined using high-resolution magnetic resonance (MR) image, followed by 3D surface reconstruction and parameterization using spherical harmonic description. Two point-wise metrics, direct displacement between the individual surface and atlas surface and its normal projection, were used to quantify the surface morphology of amygdala. Statistical analysis revealed significant correlations between the two surface metrics and trait anxiety levels, which were located around the lateral and central nucleus of right amygdala. Our results provided localized information for the association between amygdala and trait anxiety, and suggested a central role of the lateral and central nucleus of right amygdala on trait anxiety.

“…One interpretation of these findings is that state and trait anxiety have differential effects on emotional processing, and therefore, we should not expect state manipulations to necessarily produce findings consistent with trait comparisons. In support, Bourne & Vladeanu [56] report different patterns of neural activation in response to emotional faces among individuals who were either high trait anxious or had high self-reported state anxiety in response to a social stressor.…”

State anxiety and emotional face recognition in healthy volunteers

et al. 2017

High trait anxiety has been associated with detriments in emotional face processing. By contrast, relatively little is known about the effects of state anxiety on emotional face processing. We investigated the effects of state anxiety on recognition of emotional expressions (anger, sadness, surprise, disgust, fear and happiness) experimentally, using the 7.5% carbon dioxide (CO2) model to induce state anxiety, and in a large observational study. The experimental studies indicated reduced global (rather than emotion-specific) emotion recognition accuracy and increased interpretation bias (a tendency to perceive anger over happiness) when state anxiety was heightened. The observational study confirmed that higher state anxiety is associated with poorer emotion recognition, and indicated that negative effects of trait anxiety are negated when controlling for state anxiety, suggesting a mediating effect of state anxiety. These findings may have implications for anxiety disorders, which are characterized by increased frequency, intensity or duration of state anxious episodes.

“…Additionally, we examined sex differences in the present study. This is important as males have been found to be more strongly lateralised than females (e.g., Bourne, 2005;Bourne & Maxwell, 2010) and sex differences have been found in the relationship between lateralisation and schizophrenia (Mucci et al, 2005), schizotypy (Mason & Claridge, 1999) and social anxiety (Bourne & Vladeanu, 2011). As such, we predicted a negative relationship between paranoia and strength of lateralisation, and further that there would be a sex difference in this relationship.…”

“…First, previous research has shown that males are more strongly lateralised than females (e.g., Bourne, 2005;Bourne & Maxwell, 2010). More importantly, relationships between lateralisation and various individual differences have been reported for males, but not for females (e.g., Bourne & Vladeanu, 2011;Mason & Claridge, 1999;Mucci et al, 2005). Such converging evidence lends confidence to the possibility that there is a sex difference in the relationship between lateralisation and traits such as paranoia, schizotypy, and anxiety.…”

“…When asked to decide which of the two faces looks more emotive, viewers display a bias towards choosing the face with the emotional expression in their left visual field, reflecting right hemispheric superiority for processing facial emotion. However, the chimeric faces test has been found to be sensitive to individual differences, such as sex (Bourne, 2005;Rahman & Anchassi, 2012), gender identity (Bourne & Maxwell, 2010), depression (Kucharska-Pietura & David, 2003), anxiety (Bourne & Vladeanu, 2011), and emotional intelligence (Castro-Schilo & Kee, 2010).…”

Reduced strength of lateralisation in patients with schizophrenia has been reported in a number of studies. However the exact nature of this relationship remains unclear. In this study, lateralisation for processing emotional faces was measured using the chimeric faces test and examined in relation to paranoia in a non-clinical sample. For males only, those with higher scores on a paranoia questionnaire had reduced lateralisation for processing negative facial emotion. For females there were no significant relationships. These findings suggest that atypical patterns of lateralisation for processing emotional stimuli may be implicated in, or associated with, increased levels of paranoia.
