Using behavioral and neuroimaging methods, we investigate the cognitive and neural mechanisms of memory and emotion and how they change across the lifespan.

Studies of cognitive and neural aging have recently provided evidence of a shift from an early- to late-onset cognitive control strategy, linked with temporally extended activity in the prefrontal cortex (PFC). It has been uncertain, however, whether this age-related shift is unique to PFC and executive control tasks, or whether the functional location might vary […]

Aging is associated with both decreases and increases in brain activity. Whereas age-related decreases usually reflect neural decline, some age-related increases have been linked to functional compensation. Compensatory activations in older adults (OAs) are typically found in the prefrontal cortex (PFC) but in the memory domain we have also found them in the temporal lobes […]

Episodic Retrieval Processes

November 28, 2011

We investigate the neural mechanisms of various episodic retrieval processes, including recovery processes associated with MTL, control processes associated with PFC, and support processes associated with PFC and posterior parietal cortices (PPC). Recovery refers to the access of stored memory traces, in the form of specific contextual details (recollection) or in the form of a […]

Aging is associated with significant decline in the integrity of white matter (WM), and this decline contributes to age-related deficits in cognitive functions such as memory. WM integrity can be measured in vivo using diffusion tensor imaging (DTI). DTI assesses MR changes due to the movement of water molecules, which are more parallel in intact […]

Episodic memory shows substantial decline as a function of aging, and fMRI studies have linked age effects on episodic memory to changes in prefrontal cortex (PFC) and medial temporal lobe (MTL) activity (for a review, see Daselaar & Cabeza, in press). Some age-related PFC and MTL changes could be compensatory (see Compensatory Brain Activity in […]

Despite substantial age-related deficits in most cognitive abilities, emotional processing is well preserved in healthy aging, possibly due to a greater emphasis on emotion regulation. According to socioemotional selective theory (SST), aging is associated with motivational differences in allocating attention to emotional information that lead to an increase in the ratio of processing positive vs. […]

Dew and Cabeza (2011) review behavioral and neuroimaging evidence showing that, under certain circumstances, there may be an important and influential relationship between conscious and nonconscious forms of memory. Here, we offer a model predicting that the brain regions associated with explicit or implicit memory are not differentiated based on consciousness, but rather vary along […]

  Emotion processing has been shown to vary with age: relative to young adults (YAs), older adults (OAs) exhibit increased frontal activations to emotional materials as well as cognitive biases toward positive versus negative stimuli. This latter effect is hypothesized to depend on OAs’ capacity for controlled elaboration. To test this hypothesis, YAs and OAs […]

“The International Conference on Memory 5 is to be held at the University of York from the 31st July to 5th August 2011. The conference has taken place every 5 years since 1991, and has previously been held in Lancaster, Padua, Valencia, and Sydney. The programme for 2011 will include over 500 spoken presentations and […]
