Oxytocin Effects on Self and Other Processing

November 9, 2016 updated by: University of Electronic Science and Technology of China
To determine whether the neuropeptide oxytocin (OXT) influences self-processing by investigating whether it increases the endowment effect in relation to both self and others.

Detailed Description

In a double-blind, between- subject placebo (PLC) controlled design, investigator aimed to measure the effect of intranasal OXT on the endowment effect. All subjects completed a range of questionnaires measuring personality and affective traits and levels of anxiety before self-administration: Positive and Negative Affect Schedule (PANAS) , State-Trait Anxiety Inventory (STAI) , Beck Depression Inventory (BDI), self-esteem scale (SES). Subjects were asked to decide whether to buy or sell their own or others' (their mothers'/ fathers'/ classmate'/ strangers') possessions at various prices. Indifference point and brain activation were inluded into analysis as dependent variables.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Compared the indifference point between buy and sell conditions during the price phase and the specific brain region activation between oxytocin and placebo groups
Time Frame: 1 hour
Indifference point is the gap between willingness to accept and willingness to pay ;focus on the specfic brain region relasted to self-processing, such as medial prefrontal cortex, precuneus, posterior cingulate cortex, ventral striatum.
