The Influence of Cognition on Affect

190
Cognition plays a pivotal role in shaping emotional experiences, as demonstrated by Schachter and Singer’s two-factor theory of emotion. According to this model, emotion arises from a combination of physiological arousal and cognitive interpretation. The body’s physiological response to stimuli is ambiguous and only gains emotional significance through cognitive labeling. For instance, an increased heart rate and adrenaline surge while standing near an attractive person may be...

Area of Science:

  • Psychology
  • Psychiatry
  • Clinical Psychology

Background:

  • Schizotypy is a framework for psychosis proneness, mirroring schizophrenia symptoms.
  • Alexithymia, characterized by difficulties identifying/describing feelings and external thinking, is linked to schizophrenia.
  • The relationship between alexithymia and schizotypy, and the role of negative affect, requires further investigation.

Purpose of the Study:

  • To examine the associations among alexithymia dimensions, negative affect, and schizotypy.
  • To explore the network structure of these psychological constructs.
  • To investigate potential confounds like negative affect.

Main Methods:

  • Cross-sectional study in a non-clinical sample (N=420).
  • Network models estimated using Spearman correlations and EBICglasso.
  • Examined associations between alexithymia (DIF, DDF, EOT), negative affect, and schizotypy dimensions.

Main Results:

  • Difficulties in identifying feelings (DIF) linked positive/disorganized schizotypy to anxiety/stress.
  • Negative schizotypy bridged difficulties describing feelings (DDF) and external thinking (EOT) to depression.
  • Network structures were psychometrically stable.

Conclusions:

  • Difficulties in identifying feelings (DIF) and negative schizotypy are potential mechanisms for improving emotional attunement.
  • These traits may enhance resilience against distress associated with unusual self-experiences.
  • Findings suggest targets for therapeutic interventions in psychosis proneness.
