Abstract [en]

In appetitive conditioning, a neutral stimulus (CS) is conditioned to elicit a positive emotional response by pairing it with a positive/appetitive unconditioned stimulus (US). This method is useful for studying emotional disorders and emotion in general. Studying appetitive conditioning in humans has been hampered by the lack of adequate positive unconditioned stimuli. This study investigated multimodal social stimuli as potential unconditioned stimuli in an appetitive conditioning paradigm. Neutral faces (CS+’giggle’ and CS+’woohoo’) were paired with two multimodal unconditioned stimuli consisting of the same smiling face and two different sound stimuli (US‘giggle’ and US‘woohoo’). The dependent variable was participant skin conductance response (SCR) alongside participant emotional ratings of the stimuli, that together indexes the conditioned response. CS+’giggle’ was hypothesized to be rated as happier, and less fearful than CS+’woohoo’. Successful conditioning was evidenced by higher happiness ratings for both stimuli after acquisition compared to habituation. However, no effect of acquisition was found on SCR.  US’woohoo’ was also rated as more fearful and arousing and less happy and pleasant than the US’giggle’. In sum, this thesis presents a paradigm that can be used in future studies on appetitive conditioning.
