Something similar aside n the dual task condition might also happen when people are stressed or occupied by their (negative) thoughts. Block and Carr (2005), for example, showed that hen participants are tested under high-pressure conditions (for example, being told "you will be videotaped and need to do well to receive a cash payment"), performance decreases for difficult problems.
