Do children use different forms of verbal rehearsal in serial picture recall tasks? A multi-method study

Use of verbal rehearsal is a key issue in memory development. However, we still lack detailed and triangulated information about the early development and the circumstances in which different forms of rehearsal are used. To further understand significant factors that affect children’s use of various forms of rehearsal, the present study involving 108 primary school children adopted a multi-method approach. It combined a carefully chosen word length effect method with a self-paced presentation time method to obtain behavioural indicators of verbal rehearsal. In addition, subsequent trial-by-trial self-reports were gathered. Word length effects in recall suggested that phonological recoding (converting images to names - a necessary precursor for rehearsal) took place, with evidence of more rehearsal among children with higher performance levels. According to self-paced presentation times, cumulative rehearsal was the dominant form of rehearsal only for children with higher spans on difficult trials. The combined results of self-paced times and word length effects in recall suggest that ‘naming’ as simple form of rehearsal was dominant for most children. Self-reports were in line with these conclusions. Additionally, children used a mixture of strategies with considerable intra-individual variability, yet strategy use was nevertheless linked to age as well as performance levels

Sun-Protective Clothing Worn Regularly during Early Childhood Reduces the Number of New Melanocytic Nevi: The North Queensland Sun-Safe Clothing Cluster Randomized Controlled Trial

Numerous pigmented moles are associated with sun exposure and melanoma risk. This cluster randomized controlled trial aimed to determine if sun-protective clothing could prevent a significant proportion of the moles developing in young children (ACTRN12617000621314; Australian New Zealand Clinical Trials Registry). Twenty-five childcare centers in Townsville (19.25◦S), Australia, were matched on shade provision and socioeconomic status. One center from each pair was randomized to the intervention arm and the other to the control arm. Children at 13 intervention centers wore study garments and legionnaire hats at childcare and received sun-protective swimwear and hats for home use, while children at the 12 control centers did not. The 1–35-month-old children (334 intervention; 210 control) were examined for moles at baseline (1999–2002) and were re-examined annually for up to 4 years. Both groups were similar at baseline. Children at intervention centers acquired fewer new moles overall (median 12.5 versus 16, p = 0.02; 0.46 versus 0.68 moles/month, p = 0.001) and fewer new moles on clothing-protected skin (6 vs. 8; p = 0.021 adjusted for confounding and cluster sampling) than controls. Intervention children had 24.3% fewer new moles overall (26.5 versus 35) and 31.6% (13 versus 19) fewer moles on clothing-protected skin than controls after 3.5 years. Sunlight’s influence on nevogenesis is mitigated when children regularly wear UPF 30-50+ clothing covering half their body, implying that increased clothing cover reduces melanoma risk. Sun-protective clothing standards should mandate reporting of the percentage of garment coverage for childrenswear

Cognitive Training for Early-Stage Alzheimer’s Disease and Dementia

The purpose of this article is to critically review and synthesize the literature on the effects of nonpharmacological cognitive training on dementia symptoms in early-stage Alzheimer’s disease (AD) and related dementia. Electronic databases MEDLINE (PubMed), CINAHL, PsycInfo, and the Cochrane Library were searched using the keywords cognition, reality orientation, Alzheimer’s disease, psychosocial factors, cognitive therapy, brain plasticity, enriched environments, and memory training. The findings support that cognitive training improves cognition, activities of daily living, and decision making. Interventions are more effective if they are structured and focus on specific known losses related to the AD pathological process and a person’s residual ability, or are combined with cognitive- enhancing medications. Nursing implications are also discussed

Practice Guidelines for Recreation Therapy in the Care of People with Dementia (CE)

Activity is a basic human need expressed in work and leisure pursuits. Unfortunately, people with dementia have a low rate of activity participation because of associated physical and cognitive constraints. Recently, the American Therapeutic Recreation Association (ATRA) held a consensus meeting to address this issue and formulate practice guidelines for recreation therapy in the care of people with dementia. The consensus document presents an evidence-based intervention theory that draws on the science of two disciplines: nursing and recreation therapy. This article reports on the ATRA guidelines and illustrates their applicability in a case study of a resident with severe aggression associated with dementia

Therapeutic recreation as an intervention for persons with dementia and agitation: An efficacy study

Thirty-six long term care residents with dementia and agitation were selected for participation in this eight week study. During the eight week period, the participants received two different four week therapeutic recreation interventions in a clinical crossover design. These interventions included a sensorimotor program and a traditional activity program. The effects of these two programs were evaluated in terms of the effect on strength, flexibility, overall functioning, and agitation. The analysis showed that there was a significant improvement of grip strength, flexibility, and a reduction in agitation during the sensorimotor segment of the treatment. The results of this study indicate a new direction for therapeutic recreation specialists working with older adults with dementia and agitation

Frailty and dementia: How activities professionals can help through water-based activities

The medical literature defines frailty as older persons experiencing low physical activity levels, muscle weakness, slowed physical and cognitive performance, fatigue, and unlntentional weight loss.1 A person with three or more of these characteristics is considered frail. Older persons who have dementia are more likely to become disabled, to be admitted to the hospital, and to have health problems that lead to frailty. These individuals are often resistant to exercise classes and need motivation

Predicting Outcomes of Therapeutic Recreation Interventions for Older Adults with Dementia and Behavioral Symptoms

The purpose of this study was to examine the ability to predict outcomes of prescribed therapeutic recreation interventions (TRIs) for the treatment of the two major categories of disturbing behaviors in institutionalized older adults with dementia. Interventions were selected based on the participant's current level of functioning, past leisure interests, and the target behavior problem identified during baseline assessment. TRIs were then prescribed to calm individuals with agitated behaviors and (or) to alert individuals with passive behaviors. Each participant received two weeks of individually prescribed therapeutic recreation and biofeedback readings were randomly taken three times during the two-week intervention period to measure physiological change. The predicted outcome was found between 79-91% of the time when treating passivity, and between 92-100% of the time for agitation. Therapeutic recreation interventions were found to be predictable and efficacious for disturbing behaviors of dementia

Culture change and activities: Learning the lingo and making yourself invaluable

Cultures, by their very nature, can either embrace or resist change. Culture change can arise from an improved environment, due to inventions and other influences like regulations, or as a result of contact with other cultures. In its attempt to break away from traditional long-term care models culture change movement has created its own lingo
