Background: Research into specific illnesses and the development of new treatments may only become possible as new technologies become available. When used for research, such technologies may best be described as "intrusive", in that they require a considerable willingness and commitment on the part of the participants. This has…

Stage theories are prominent and controversial in science. One possible reason for their appeal is that they provide order and predictability. Participants in Experiment 1 rated stage theories as more orderly and predictable (but less credible) than continuum theories. In Experiments 2-5, we showed that order threats increase the appeal of stage…

Studies of incidental category learning support the hypothesis of an implicit prototype-extraction system that is distinct from explicit memory (Smith, 2008). In those studies, patients with explicit-memory impairments due to damage to the medial-temporal lobe performed normally in implicit categorization tasks (Bozoki, Grossman, & Smith, 2006;…

This review article examines current knowledge about the efficacy of art therapy based on the findings of 8 randomized controlled trials (RCTs) conducted with adult populations from 2008-2013 that met a high standard of rigor. Of these studies, all but one reported beneficial effects of art therapy. Review findings suggest that art therapy may…

Purpose: The stigma experienced by the family members of an individual with a stigmatized illness is defined by 3 dimensions: caregiver stigma, lay public stigma, and structural stigma. Research in the area of mental illness suggests that caregivers' perception of stigma is associated with increased burden. However, the effect of stigma on…

Dementia may be more common in older adults with intellectual disability (ID) than in the general population. The increased risk for Alzheimer's disease in people with Down syndrome (DS) is well established, but much less is known about dementia in adults with ID who do not have DS. We estimated incidence rates from a longitudinal study of…

The high prevalence of sleep disorders, particularly obstructive sleep apnea, is well established in children with Down syndrome. However, only a few studies have focused on older children and young adults in this population. Given the presence of sleep disorders and the early emergence of Alzheimer's disease, more work is needed to examine the…

Advances in dual-retrieval models of recall make it possible to use clinical data to test theoretical hypotheses about mild cognitive impairment (MCI) and Alzheimer's dementia (AD), the most common forms of neurocognitive impairment. Hypotheses about the nature of the episodic memory declines in these diseases, about decline versus sparing of…

This study assessed whether four patients with a diagnosis of Alzheimer's disease could make independent phone calls via a computer-aided telephone system. The study was carried out according to a non-concurrent multiple baseline design across participants. All participants started with baseline during which the telephone system was not available,…

We conducted 2 studies on reinforcer preference in patients with dementia. Results of preference assessments yielded differential selections by 14 participants. Unlike prior studies with individuals with intellectual disabilities, all participants showed a noticeable preference for leisure items over edible items. Results of a subsequent analysis…

Purpose: An increasing number of elderly individuals are diagnosed with Alzheimer's disease and related disorders (ADRD), many of whom receive daily caregiving from spouse or adult child. Caregiving is a "cultural activity," and as such it is strongly influenced by sociocultural beliefs about caregiving and how it should be enacted.…

This study assessed whether three patients with Alzheimer's disease could learn to use urine alarms and caregivers' prompts to eliminate large urinary accidents. As soon as the patient began to release urine, the alarm system presented auditory and vibratory signals. In relation to those signals, the caregiver would prompt/encourage the patient to…

The present study (a) extended the assessment of an orientation program involving auditory cues (i.e., verbal messages automatically presented from the destinations) with five patients with Alzheimer's disease, (b) compared the effects of this program with those of a program with light cues (i.e., a program in which strobe lights were used instead…

Over the next 20 years the number of Americans diagnosed with dementia is expected to more than double (CDC, 2007). It is, therefore, an important public health initiative to understand what factors contribute to the longevity of a healthy mind. Both default mode network (DMN) function and increased aerobic fitness have been associated with better…

A randomized controlled trial examined whether the diagnostic process for Alzheimer's disease and other dementias may be influenced by knowledge of the patient's education and/or self-reported race. Four conditions were implemented: diagnostic team knows (a) race and education, (b) education only, (c) race only, or (d) neither. Diagnosis and…
