The current study employed a Pavlovian conditioning paradigm to investigate the influence of pre-stimulus unconscious threat anticipation on subsequent fear responses in associative learning. Additionally, we explored the differences in pre-stimulus anticipation among individuals with varying levels of anxiety. Electrodermal response (EDA) was chosen as a primary measure due to its robustness in fear conditioning paradigms. Moreover, the State-Trait Anxiety Inventory (STAI) was utilized to assess anxiety levels in participants. Twenty-seven subjects were recruited to determine if pre-stimulus skin conductance responses (SCR) would exhibit stimulus-specific patterns influenced by implicit cues (L-shaped configurations) that indicated an upcoming face or a house …
Threat-Related Attentional Bias In Relation To Anxiety And Depressive Symptoms In The General Population: The Potential Role Of Sex Effects, Beril Yaffe
Dissertations, Theses, and Capstone Projects
Heightened sensitivity to relevant environmental stimuli (attentional bias) has been observed in relation to clinical and non-clinical anxiety and depression symptoms. While depression symptoms are associated with sensitivity to disorder and self-relevant words, hypervigilance to threatening stimuli is observed in relation to anxiety symptoms. Furthermore, attentional bias has been shown to play an important role in the development and maintenance of depressive and anxiety disorders. Accordingly, a large body of literature has examined threat-related attentional bias in relation to symptoms of anxiety and depression. However, several methodological inconsistencies exist across studies, including variability in definitions of threat, lack of consideration …
