The subjective-objective deficit paradox in schizotypy extends to emotion regulation and awareness.

There is an emerging subjective-objective deficit paradox in schizotypy. Individuals with schizotypy report severe subjective complaints in several key functional domains commensurate with that of individuals with schizophrenia. However, objective assessments of the same domains show relatively intact performance. We examined whether this subjective-objective deficit paradox extends to two closely linked affective processes: emotion regulation and awareness. Individuals with elevated social anhedonia (SocAnh; n = 61) and elevated perceptual aberration/magical ideation (PerMag; n = 73) were compared to control participants (n = 81) on subjective and objective measures of emotion regulation and awareness. Subjective measures included self-report questionnaires assessing regulatory ability, attention to emotion, and emotional clarity. Implicit emotion regulation was assessed by the Emotion Regulation-Implicit Association Test (ER-IAT) while objective emotional awareness was assessed by the Levels of Emotional Awareness Scale (LEAS), a performance-based test. Results showed that both SocAnh and PerMag groups reported notable deficits in almost all subjective measures relative to controls (composite ds > 0.55). In contrast, performance on ER-IAT and LEAS was very similar to controls (composite ds < 0.11). The current study suggests that the subjective-objective deficit paradox extends to emotion regulation and awareness, highlighting the importance of higher-order cognitive bias in understanding emotional abnormalities in schizotypy.

Differential emotional abnormalities among schizotypy clusters.

Schizotypy, a multidimensional personality organization that reflects liability to develop schizophrenia-spectrum disorders, has been associated with a number of emotional abnormalities. Yet, the exact nature of any emotional abnormalities in schizotypy is relatively unclear. Using an ethnically diverse nonclinical sample (N = 2637), the present study identified homogenous clusters of individuals based on positive and negative schizotypy dimensions and explored three interrelated domains of emotion traits closely tied to functional outcomes and quality of life: affective experience, emotional awareness, and meta-level emotions. Consistent with prior research, four schizotypy clusters were obtained: low ("nonschizotypic"), high positive, high negative, and mixed (high positive and high negative). Regarding emotion correlates of schizotypy clusters, the mixed cluster was found to be the most deviant on almost all emotion traits (e.g., heightened trait negative affect, diminished emotional clarity), suggesting that the effects of positive and negative schizotypy are additive. In addition, positive and negative schizotypy clusters were associated with differential abnormalities, with the negative cluster presenting a wider range of, and more severe, impairments compared to the low cluster (e.g., reduced trait positive affect and reduced attention to positive emotion). The current study highlights the heterogeneity in emotional traits among schizotypy dimensions and the importance of studying the mixed schizotypy in terms of emotional dysfunction.

Emotional word usage in groups at risk for schizophrenia-spectrum disorders: An objective investigation of attention to emotion.

Both extreme levels of social anhedonia (SocAnh) and extreme levels of perceptual aberration/magical ideation (PerMag) indicate increased risk for schizophrenia-spectrum disorders and are associated with emotional deficits. For SocAnh, there is evidence of self-reported decreased trait positive affect and abnormalities in emotional attention. For PerMag, there is evidence of increased trait negative affect and increased attention to negative emotion. Yet, the nature of more objective emotional abnormalities in these groups is unclear. The goal of this study was to assess attention to emotions more objectively in a SocAnh, PerMag, and control group by using a positive (vs. neutral) mood induction procedure followed by a free writing period. Linguistic analyses revealed that the SocAnh group used fewer positive emotion words than the control group, with the PerMag group falling in between the others. In addition, both at-risk groups used more negative emotion words than the control group. Also, for the control group only, those in the positive mood induction used more positive emotion words, suggesting their emotions influenced their linguistic expression. Overall, SocAnh is associated with decreased positive emotional expression and at-risk groups are associated with increased negative emotional expression and a decreased influence of emotions on linguistic expression.
