The existence and importance of psychosocial needs experienced by spouses of cancer patients have been demonstrated repeatedly. In order to reduce these needs, our study assesses the efficacy of the combination of two psychotherapeutic methods: psychosocial needs' organisation into a hierarchy and problem solving. Our longitudinal and randomized study comprises three assessment times, separated from three weeks, (T0, T1 and T2) and two groups (experimental and control). At T0, both groups realize the hierarchy of needs. Between T0 and T1, only the experimental group practices problem solving. Then, between T1 and T2, the control group practices this method too. Questionnaires administered at each assessment time are: sociodemographic questionnaire, Hospital Anxiety and Depression Scale (HADS), Psychosocial Needs Inventory (PNI), self-efficacy questionnaire (GSES). Between T0 and T1, a general improvement in scores is expected in both groups: it is expected to be higher in the experimental group who completed the problem solving. Between T1 and T2, scores in the control group should improve to join those obtained by theexperimental group at T1. Thirty-seven people participated: experimental group (N=19, male=12, female=7) and control group (N=18, male=11, female=7). The results confirm our initial hypotheses and emphasize the importance of taking care of cancer patients' spouses. [less ▲]

Perceptual and motor inhibition were examined using conflict resolution tasks for 12 children with traumatic brain injury and 24 matched controls. Direct comparisons of inhibition performances between the two groups showed a specific and disproportionate impairment of motor inhibition (compared with perceptual inhibition) for the children with traumatic brain injury, which suggests that inhibition processes might be differentially impaired in children after traumatic brain injury.

Patients with Alzheimer's disease (AD) relying predominantly on familiarity for recognition, research has suggested that they may be particularly susceptible to memory illusions driven by conceptual fluency. Using the Jacoby and Whitehouse [Jacoby, L.L., & Whitehouse, K. (1989). An illusion of memory: False recognition influenced by unconscious perception. Journal of Experimental Psychology: General, 118, 126-135] illusion paradigm, we extended these findings and found that AD patients were also sensitive to perceptually driven false recognition. However, AD patients were equally able to disregard perceptual fluency when there was a shift in the sensory modality of the study and test stages. Overall, these findings support the notion that patients with AD can be susceptible to fluency-based memory illusions but these patients can strategically control the fluency attribution following their metamemory expectation in exactly the same way as elderly adults and young adults.

Alzheimer's disease is characterized by a progressive deterioration of various cognitive and behavioral abilities and it also has a health impact on the patients’ caregiver. Our aim was to determine the patient (and to a lesser extent the caregiver’s) characteristics that contribute most to the caregiver burden. We used the baseline data from the ICTUS study, a European longitudinal cohort of patients with mild to moderate AD. Data from 1091 patients and their caregivers has been used for analysis. Three principal components analyses were performed on variables from the domains of cognition, neuropsychiatric symptoms and daily function using MMSE plus ADAS-Cog, NPI and IADL subscores respectively. These were followed by a stepwise logistic regression to identify patient characteristics which best predict caregiver burden. The regression model (R2 = 0.35, p < .001) shows that the best explanatory variables are (1) neuropsychiatric symptoms (NPI), (2) difficulties in the IADL, (3) time taken by caregiving, (4) demographic variables such as caregiver’s age and patient sex and (5) severity of cognitive impairment. In conclusion, our results demonstrate that although the strongest determinant of the caregiver burden is behavioral disturbance, the impact of the degree of cognitive impairment on burden is also significant.

The aim of this study was to compare the performance of elderly and young participants on a series of memory tasks involving either intentional or unintentional inhibitory control of memory content. Intentional inhibition processes in working and episodic memory were explored with directed forgetting tasks and in semantic memory with the Hayling task. Unintentional inhibitory processes in working memory, long-term memory, and semantic memory were explored with an interference resolution task, the retrieval practice paradigm, and the flanker task, respectively. The results indicate that elderly participants' performance on the two directed forgetting tasks and the Hayling task is lower than that of young ones, and that this impairment is not related to their initial memory capacity. This suggests that there is a specific dysfunction affecting intentional inhibitory control of memory contents in normal ageing. [less ▲]

Deficits in inhibitory abilities are frequently observed in normal aging. However, few studies have explored the generality of these deficits in a single group of participants. Here, we used an adaptation of the Simon task to differentially assess perceptual and motor inhibition using the same stimuli and task design and to determine whether these processes use separate or shared cognitive resources. We were interested in determining whether (1) normal aging is associated with the use of separate (as previously evidenced in young participants) or similar cognitive resources to perform perceptual and motor inhibition tasks; (2) older participants present a specific impairment in one of these two processes. Analyses of reaction times indicated that motor and perceptual inhibitory processes share some cognitive resources and both are impaired in normal aging. These results can be interpreted by considering that a dedifferentiation process is responsible for the inhibitory deficits presented by older participants. [less ▲]

This paper proposes the use of the stochastic frontier approach to analyse the relationship between cognitive performance, retirement and non-professional activities of the 50+ individuals using data from three surveys conducted in Europe (the Survey on Health, Ageing and Retirement in Europe and the English Longitudinal Survey on Ageing) and United States (the Health and Retirement Study). Next to the strong relationship between cognitive performance, age and education, this study highlights the negative effect of retirement and the positive impact of non-professional activities and social contacts.

The aim of this paper was to use a parametric stochastic frontier approach (coming from the economic literature) to explore the impact of the concept of activity (taken in a broad sense: i.e., including both professional and non-professional activities) on the constitution and the care of cognitive reserve among the European population aged 50 and up. For this purpose, we use individual data collected during the first wave of SHARE (Survey on Health, Ageing and Retirement in Europe) performed in 2004. The advantages of this survey were (1) it included a large population (n = 18,623) geographically distributed throughout Europe; and (2) it simultaneously analyzed several dimensions (physical and mental health, mobility, occupational activities, socioeconomic status, etc.). Our results confirm the positive impact of occupational activities on the cognitive functioning of elderly people. These results are discussed in terms of the prevention of cognitive aging and Alzheimer’s disease, and more particularly of retirement policy issues. [less ▲]
