A study is reported in which the relations among normal aging, source amnesia, and frontal lobe functioning were explored. Twenty-four older adults (aged 60-84 years) were tested on their ability to remember where they had acquired new factual information; they were also given the Wisconsin Card Sorting Test (WCST), a test of verbal fluency, and other psychometric tests. The degree of source amnesia in this normal sample correlated with age, verbal fluency, and some measures from the WCST. Source amnesia was not related to Performance IQ, however, or to a measure of fact recall. The implications for the relations among aging, memory, and frontal lobe functions are discussed.

Recent research on the factors that mediate the emotional wellbeing of the caregivers of dementia sufferers is reviewed. The roles of such factors as the caregiver's attributional style and coping strategies, the caregiver's relationship with the dementia sufferer, and levels of formal and informal support are discussed with reference to identifying those caregivers who are particularly vulnerable to emotional disorder or strain.

This study explored the quality of marital relationship between dementia sufferers and their spouse caregivers. It assessed the quality of the relationship (level of intimacy) prior to the onset of dementia and also at the time of the study. Caregivers who experienced lower levels of marital intimacy, both currently and before the onset of dementia, were found to have higher levels of perceived strain and depression. The decline in intimacy following the onset of dementia was estimated from the difference between the levels of past and present intimacy. Caregivers who experienced a greater loss of intimacy had a higher level of depression, but did not show evidence of increased perceived strain. It is speculated that a poor premorbid relationship makes caregiving more stressful because of a greater difficulty in performing the caregiving role. In addition, it is suggested that a poor premorbid relationship or high loss of intimacy acts as a vulnerability factor, predisposing the caregiver to depression.

The paper explores a distinction between different kinds of lapse of concentration in depressed patients. The strategy is to begin with the phenomenological distinction between the mind (a) 'wandering' on to something else or (b) going 'blank'. Blanking, but not mind-wandering, is associated with longer planning times on the 'Tower of London' task. In contrast, mind-wandering but not blanking, is associated with poor memory for prose, at least under ordinary processing conditions. Different phenomenal forms of concentration problem thus have different task performance correlates. A tentative formulation is offered in terms of Shallice's model of the regulation of attention. Mind-wandering is seen as a problem of 'contention scheduling', and blanking as the result of generalized inhibition by the Supervisory Attentional System. It is evident that not all performance deficits in depression can be attributed to the cognitive capacity taken up by competing thoughts.

Recent research shows that the demands of the caregiving role are experienced differently by men and women. Both the subjective and the objective strain and burden appear to be greater in female carers of dementia sufferers, and factors that influence this include differences in role expectations and coping strategies. These findings have implications for the provision of services for dementia sufferers and their carers.
