Delay Discounting - hypothetical

A child is given a series of option between a variable immediate monetary reward and 10 Euros after a certain delay. The delay of the 10 Euro reward varies between 2, 30, 180, or 365 days.

Each trail starts with the question if the child would rather have a specific immediate reward now, or 10 Euros after a specific delay. Based on the choices of the child, the task determines an indifference point per delay. That is, when the immediate reward has the same subjective value as the 10 Euros at that delay.
