Considerable evidence suggests that episodic memory and foresight rely on the same underlying cognitive processes. Some theorists have suggested that the key role of episodic foresight is to allow an individual to disengage from current states to plan for future needs. However, the contribution of episodic cognition to this type of planning has not been investigated. We present two experiments exploring future-state planning in 3-6 year old children and healthy young adults, finding that both groups were consistently biased towards current states. We further found that there were few relationships between episodic memory ability and future-state planning. Where there was a relationship, the degree of bias was positively related to episodic memory ability, such that those with better episodic were more biased by their current motivational state. These findings are consistent with previous research suggesting that episodic cognition is particularly vulnerable to bias from current feelings. We propose an account in which episodic cognition allows for cross-talk between current and future motivational states, and that while this can aid prospective decision making in some scenarios, it may hinder it in others.
