Individuals high in self-reported Intolerance of Uncertainty (IU) tend to view uncertainty as unbearable and stressful. Notably, IU is transdiagnostic, levels are observed across many different emotional disorders (e.g., anxiety, depression). Research has primarily focused on how evokes modulates states such fear anxiety. However, recent research suggests that may have relevance for a broader range states. Here, an online survey was conducted examine whether negative fear/anxiety, sadness/upset, anger/frustration, disgust) positive happiness/joy, excitement/enthusiasm, surprise/interest) Findings within community sample (n = 231) revealed individuals with higher report: (1) general under ambiguity more likely evoke less states, (2) risk (3) heightens existing dampens Importantly, these IU-related findings remained when controlling current experiences distress, anxious arousal, anhedonic depression. Taken together, suggest involved evoking modulating wide array phenomena, which transdiagnostic models treatment plans disorders.

Exposure-based therapy for anxiety disorders involves confrontations with feared but innocuous stimuli to promote inhibitory safety learning and fear extinction. Little is known about factors that may impede generalization of extinction memory from used during exposure similar later encountered. Trait a vulnerability factor developing anxiety-related associated deficient learning. In this preregistered study, we tested whether high-trait compared low-trait anxious individuals would show less Intolerance uncertainty worry were also measured as closely related dimensions dispositional negativity. Participants completed conditioning paradigm three phases: acquisition, extinction, generalization. Dependent measures online threat expectancy distress ratings. Fear acquisition successful in both groups, there no group differences These results suggest high trait does not memory.

Previous research has demonstrated that individuals with high levels of Intolerance Uncertainty (IU) have difficulty updating threat associations to safety associations. Notably, prior focused on measuring IU-related differences in and learning using arousal-based measures such as skin conductance response. Here we assessed whether could be captured eye-tracking metrics linked gaze behaviours dwelling scanning. Participants (N = 144) completed self-report questionnaires assessing IU trait anxiety. Eye movements were then recorded during each conditioning phase: acquisition, extinction learning, retention. Fixation count fixation duration served indices conditioned responding. Patterns typically reported for physiology observed the acquisition some extent but not There was little evidence specific between disrupted (e.g., greater differential responses vs. safe cues retention). While there tentative associated shorter durations scanning) retention, this effect did remain after controlling anxiety similarly predicted overall further However, only IU-based remained significant learning. Our results inform models anxiety, particularly relation how individual modulate behaviour conditioning.

Uncertainty is a core component of threat and associated learning processes. One methodological factor impacting uncertainty in paradigms the reinforcement rate, which refers to proportion times cue reinforced with an aversive stimulus. This study tested effect partial vs continuous on / safety discrimination learning, as indexed by skin conductance response (SCR). Using within-participants design, fifty-nine participants completed task three colored shapes were paired electric shock at schedules 100% (CS+), 50% (CS+) 0% (CS-). In addition, examined relationship between Intolerance scale (IU) two subscales – inhibitory prospective IU learning. The data show heightened SCR condition all stimuli, but limited evidence enhanced Furthermore, no association was observed total score threat-safety discrimination. However, using two-factor model IU, findings showed higher diminished discrimination, respectively. These results contribute fast-growing literature exploring how inherent predictors threat, individual differences sensitivity uncertainty, interactions these factors, can shape acquisition memory.
