- Verbal fluency patterns in amnestic mild cognitive impairment are characteristic of Alzheimer's type dementiaKelly J Murphy
Psychology Department, Baycrest Centre for Geriatric Care, Toronto, Ontario, Canada
J Int Neuropsychol Soc 12:570-4. 2006..This aMCI fluency pattern reflects degradation of semantic networks demonstrating that initial neuropathology may extend beyond known early changes in hippocampal regions...
- Episodic, but not semantic, autobiographical memory is reduced in amnestic mild cognitive impairmentKelly J Murphy
Department of Psychology, Baycrest, 3560 Bathurst Street, Toronto, Ontario, Canada, M6A 2E1
Neuropsychologia 46:3116-23. 2008..In contrast, the preservation of autobiographical semantic memories in aMCI suggests neural systems, such as lateral temporal cortex, that support these memories, may remain relatively intact...
- Word-list-learning performance in younger and older adults: intra-individual performance variability and false memoryKelly J Murphy
The Rotman Research Institute of Baycrest Centre, Toronto, Ontario, Canada
Neuropsychol Dev Cogn B Aging Neuropsychol Cogn 14:70-94. 2007..The findings presented here are consistent with the notion that changes in cognition with aging in part reflect age-related decline in frontal lobe function...
- Item and associative memory in amnestic mild cognitive impairment: performance on standardized memory testsAngela K Troyer
Department of Psychology, Baycrest Centre for Geriatric Care, Toronto, Ontario, Canada
Neuropsychology 22:10-6. 2008..Incorporating measures of associative recall into clinical evaluations of individuals with memory change may be useful for detecting aMCI...
- Does lateral parietal cortex support episodic memory? Evidence from focal lesion patientsPatrick S R Davidson
Rotman Research Institute, Baycrest Centre, Toronto, Canada
Neuropsychologia 46:1743-55. 2008..Although the exact mechanisms remain to be elucidated, lateral parietal damage appears to impair some aspects of episodic memory...
- Staying on the job: the frontal lobes control individual performance variabilityDonald T Stuss
Rotman Research Institute, Baycrest Centre for Geriatric Care and University of Toronto, Ontario, Canada
Brain 126:2363-80. 2003..Damage to different frontal regions causes different profiles of abnormal variability. Fluctuations in performance of a task may underlie some of the reported difficulties in daily tasks reported by patients with frontal injuries...

- Age-related elevations in intraindividual variability on associative memory tasksSusan Vandermorris
a Neuropsychology and Cognitive Health, Baycrest, Toronto, ON, Canada
Neuropsychol Dev Cogn B Aging Neuropsychol Cogn 20:722-34. 2013..Findings suggest that IIV may reflect age-related decline in distributed neural networks, including medial temporal regions, in addition to frontal systems dysfunction...
- Age-related differences in associative memory depend on the types of associations that are formedAngela K Troyer
Psychology, Baycrest Centre, Toronto, Ontario, Canada
Neuropsychol Dev Cogn B Aging Neuropsychol Cogn 18:340-52. 2011..The discussion focuses on the roles of recollection and familiarity in supporting associative memory as well as implications for the remediation of age-related memory decline...
- Changing everyday memory behaviour in amnestic mild cognitive impairment: a randomised controlled trialAngela K Troyer
Department of Psychology, Baycrest Centre for Geriatric Care, Toronto, Canada
Neuropsychol Rehabil 18:65-88. 2008..This incorporation of practical memory strategies into daily routines could potentially provide the means for maintaining functional independence by individuals with MCI, an issue to be addressed in future research...
- Lapses of intention and performance variability reveal age-related increases in fluctuations of executive controlRobert West
Rotman Research Institute of Baycrest Centre, Toronto, Ontario, Canada
Brain Cogn 49:402-19. 2002..These and other data are consistent with the proposal that aging is associated with a decrease in the stability of executive control over time...

- Dissociations within the anterior attentional system: effects of task complexity and irrelevant information on reaction time speed and accuracyDonald T Stuss
The Rotman Research Institute, Baycrest Centre for Geriatric Care, Toronto, Ontario, Canada
Neuropsychology 16:500-13. 2002..The frontal lobes, particularly right dorsolateral, were required to inhibit an incorrect response. There are at least 3 functionally and anatomically separable anterior attentional processes...

Vision Research Laboratories, School of Psychology, University of Aberdeen, Aberdeen AB24 2UB, Scotland, UK
Neuropsychologia 44:1584-94. 2006..It is possible that D.F.'s degraded performance reflects a relative (though not complete) preservation of categorical coding within the ventral stream, despite a loss of coordinate coding there...
