Eligibility

Age

18 Years to 99 Years

Inclusion criteria

Inclusion criteria: All subjects will be female healthy adults (age 18-50) with self-reported normal or corrected-to-normal vision and normal hearing.

Exclusion criteria

Exclusion criteria: Individuals with a history of neurological or psychiatric disease or current medication affecting the central nervous system (CNS) will be excluded from the experiment. Individuals having ferromagnetic objects in the body will not be allowed to participate. Individuals wearing jewellery, metal objects, external prostheses, cards, keys, etc. will be asked to leave these in a locker outside the MRI scanner room. People who refuse to comply with the safety requirements will be excluded. Participants will be asked to fill in safety instruction and screening forms. Individuals who refuse to fill in this form or do not fully comply with the safety rules for MRI exams will not be allowed to do the experiment.

Design outcomes

Primary

Measure	Time frame
Behavioural The main behavioural parameter is the observers* inferring accuracy, which we will calculate as the percentage of items correctly identified as preferred versus not preferred choice. As a second measure of inferring accuracy, we will calculate Pearsons correlation between observers and consumers* ratings on preference (pictures) and emotional experience (commercials). Self-assessment manikin (SAM) scale will be used to measure consumers* emotional experience (valance and arousal) in relation to visual stimuli (pictures and commercials). The observer will assess consumers* emotional expressiveness and choice preferences using a 7-point Likert scale. Neuroimaging The neural activity of the participant performing the observer role will be measured with functional magnetic resonance imaging (fMRI) which will be derived from blood-oxygenation-level-dependent (BOLD) signals in regions of interest (ROI). The main study parameter is the level of inter-subject correlation (ISC) between observers* neural activity. We will compare the level of ISC across conditions (social versus alone) and in relation to inferring performance (successful versus non-successful).	—
