My main research interests are long-term memory retrieval and forgetting. Key questions in my research are:
- What factors facilitate and hinder memory retrieval?
- Why do we forget?
- How is involuntary retrieval different from voluntary retrieval?
- Is it possible to suppress retrieval of unwanted memories?
- What cognitive processes enable us to selectively retrieve a specific memory among all memories that are stored in the long-term memory?
I am investigating these research questions with electrophysiological (EEG/ERP) methods, behavioural measures and neuropsychological studies of patients with neurodegenerative diseases.
Students that want to be involved in any of my projects (as part of their thesis project) are encouraged to contact me.
From Cue to Recall: The Temporal Dynamics of Long-Term Memory Retrieval
What cognitive processes are involved in long-term memory retrieval and when are these processes recruited? These research questions are investigated in my dissertation project. I am especially interested in interference and interference resolution during long-term memory retrieval. Retrieval cues are typically related to several memories and in order to retrieve the memory that currently is relevant it is necessary to resolve interference from competing irrelevant memories. My research investigates the cognitive mechanisms underlying retrieval competition and the processes that enable us to select the currently relevant memory among competing irrelevant memories. I am also interested in the neural mechanisms underlying involuntary memory retrieval. Involuntary retrieval of unwanted memories is a core symptom in many clinical disorders including post-traumatic stress disorder, obsessive compulsive disorder and depression. This part of the dissertation project has clear relevance for clinical psychology, since involuntary retrieval of unwanted memories is common in several psychiatric disorders including post-traumatic stress disorder, depression and obsessive compulsive disorders.
I am teaching cognitive psychology, cognitive neuroscience and clinical neuropsychology both at the stand alone courses and at the program in clinical psychology.
