    Abstract
    People with schizophrenia (SCZ) have been shown to have prospective memory (PM) deficits. PM refers to the ability to remember to perform delayed intentions in the future and plays an important role in everyday independent functioning in SCZ. To date, few studies have investigated methods to improve PM in SCZ. This study aimed to examine whether implementation intention can improve PM performance and to explore its underlying mechanisms. Fifty people with SCZ and 50 demographically matched healthy controls (HC) participated in this study. Participants were randomly assigned to an implementation intention condition or a control ...

    People with schizophrenia (SCZ) have been shown to have prospective memory (PM) deficits. PM refers to the ability to remember to perform delayed intentions in the future and plays an important role in everyday independent functioning in SCZ. To date, few studies have investigated methods to improve PM in SCZ. This study aimed to examine whether implementation intention can improve PM performance and to explore its underlying mechanisms. Fifty people with SCZ and 50 demographically matched healthy controls (HC) participated in this study. Participants were randomly assigned to an implementation intention condition or a control instruction condition. Participants were required to make PM responses when PM cue words appeared while they were undertaking an ongoing task with two levels of cognitive load (1-back or 2-back). Results showed that people with SCZ were impaired in PM, and implementation intention improved PM performances for both SCZ and HC. Implementation intention improved PM performance in SCZ in both the low and the high cognitive load conditions without ongoing task cost, suggesting that implementation intention improved PM remembering in an automatic way. These results indicate that implementation intention may be a beneficial technique for improving PM performances in people with SCZ.
