In a project supported by an NH&MRC Development grant and the Telstra Broadband fund I am creating a computerized memory test for the early detection of Alzheimer’s disease. The test has several novel features including the use of voice recognition technology and the ability to generate an unlimited number of alternative forms.
In a current ARC grant several collaborators and I are working on memories for words/concepts when they are embedded in an extended associative network. This work has allowed us to refute two widely held theories about human memory. This work has already been applied to memories for companies/brands sponsoring events and it is likely that there will be important implications for education and for disordered thought processes, such as those in Schizophrenia.
I have also been looking at memory errors (“false memories”). This work has provided support for the Dennis and Humphreys (2001) theory. It may also provide a foundation, which could lead to an enhanced understanding of false memories for real world events, such as memories for sexual abuse.
I am also working on the control processes in memory access. Here I am trying to undersand the role of context, the difficulties involved in maintaining or reinstating context and the different kind of memory retreival operations.
