Abstract
In clinical neuropsychology, source monitoring deficits have been classically attributed to executive dysfunction. Nevertheless, in this review we identified only 16 papers that provided statistical data about the relationships between source monitoring and executive processes. Surprisingly, they reported either a total, partial or non-existent relationship between source monitoring and executive tasks. In order to understand and explain these contradictions, we classified the source and executive tasks of the 16 papers according to two well-accepted definitions. Source tasks were classified using the Source Monitoring Framework (Johnson, Hashtroudi, & Lindsay, 1993) which specifies reality and external and internal source monitoring. Executive tasks were classified according to the model of Miyake Friedman, Emerson, Witzki, and Howerter (2000) which specifies complex, shifting, updating and inhibition tasks. We found that evaluation of reality and internal source monitoring was limited. Regarding executive functions, there was no assessment of updating and only a limited assessment of shifting and inhibition. Therefore, the relationship between source monitoring and executive functions remains an open question. Our findings point to the need for the simultaneous assessment of source monitoring and executive functions as defined by multidimensional theoretical frameworks. Such investigations would help in understanding the relationship between specific source monitoring deficits and specific executive decline in clinical populations.
