The driving performance of individuals with mild cognitive impairment (MCI) is suboptimal when compared to healthy older adults. It is expected that the driving will worsen with the progression of the cognitive decline and thus, whether or not these individuals should continue to drive is a matter of debate. The aim of the study was to provide support to the claim that individuals with MCI can ...

The current project examined the impact of differential motivation on baseline versus post-mild traumatic brain injury (MTBI) neuropsychological measures in athletes. Collegiate athletes were administered a neuropsychological battery prior to and post-MTBI. High Motivation at Baseline (HMB) and Suspect Motivation at Baseline (SMB) groups were established for each measure based on whether baseli...

We conducted three experiments to reproduce and extend Perone and Courtney's (1992) study of pausing at the beginning of fixed-ratio schedules. In a multiple schedule with unequal amounts of food across two components, they found that pigeons paused longest in the component associated with the smaller amount of food (the lean component), but only when it was preceded by the rich component. In o...

Here, we present evidence that the alleged correction of the typification of Tradescantia crassula recently proposed by Pellegrini, Forzza and Sakuragui is erroneous. Furthermore, we clarify misconceptions concerning the epitype of T. crassula, the specimen B-100521014, which was collected by Friedrich Sello in southern Brazil, and is not original material for T. crassula.

Policies that include children with developmental disabilities in community life increase their opportunities but also create new challenges and introduce certain risks. When high school classmates of a teenaged girl with mild mental retardation were convicted of sexually abusing her, a prominent advocate for people with disabilities noted, “The need to be loved can be a trap for the most capab...

Deficits in semantic memory in individuals with amnestic mild cognitive impairment (aMCI) have been previously reported, but the underlying neurobiological mechanisms remain to be clarified. We examined event-related potentials (ERPs) associated with semantic memory retrieval in 16 individuals with aMCI as compared to 17 normal controls using the Semantic Object Retrieval Task (EEG SORT). In th...

OBJECTIVES The present study examined the role of enactment in source memory in a cognitively impaired population. As seen in healthy older adults, it was predicted that source memory in people with mild cognitive impairment due to Alzheimer's disease (MCI-AD) would benefit from the self-reference aspect of enactment. METHOD Seventeen participants with MCI-AD and 18 controls worked in small g...

OBJECTIVE The current study sought to determine if the Kaplan-Baycrest Neurocognitive Assessment (KBNA) was capable of discriminating individuals with subjective memory complaints associated with depression from individuals with mild cognitive impairment (MCI). METHODS Scores on 12 subtests of the KBNA were compared for 27 participants with MCI and 28 participants being treated for depression...

This paper presents the French NSF project ”The Impact of a Domestic Robot on the Psychological and Cognitive State of the Elderly with Mild Cognitive Impairment” (ROBADOM). This project aims at conceiving a robot with emotions and language in order to support at home the elderly with Mild Cognitive Impairment (MCI), living alone at home, and suffering or not from depression. The objective of t...

OBJECTIVES Little information is available regarding the extent of strategy use and factors that affect strategy use in amnestic mild cognitive impairment (aMCI). This study aimed to compare spontaneous strategy use and beliefs about the controllability of memory between aMCI and healthy older adult (HOA) samples and to explore the relationships between beliefs, strategy use, and memory perform...
