Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Participants are randomly assigned to the cold or warm water condition of the socially evaluated cold pressor test (SECPT; Schwabe et al., 2008). Thereafter, participants of both conditions receive 45 minutes of in-vivo exposure to spiders. The effects of stress on exposure-based anxiety reductions toward spiders (treated fear stimulus) and cockroaches (untreated fear stimulus to assess generalization of treatment outcome) are assessed on the behavioral, subjective and physiological level at pretreatment, posttreatment (24 hours after exposure) and follow-up (4 weeks after exposure).

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Stress + Exposure
Stress Condition: Cold water condition of the socially evaluated cold pressor test (SECPT; Schwabe et al, 2008).
Cold water condition
Cold water condition of the SECPT. Participants immerse their hand into ice-cold water (0-3°C). During the SECPT, participants are videotyped and monitored. After the SECPT, participants will receive 45 minutes of in-vivo exposure to spiders
Control + Exposure
Control condition: Warm water condition of the SECPT.
Warm water condition
Warm water condition of the SECPT. Participants immerse their hand into warm water (36-37°C). Participants are neither videotyped nor monitored during the whole procedure. After the SECPT, participants will receive 45 minutes of in-vivo exposure to spiders.
