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

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

Treatment Fidelity Plan for an Activity Intervention Designed for Persons with Dementia

The testing of psychosocial interventions in a clinical trial poses many challenges to maintaining a rigorous experimental protocol and to delivering the interventions uniformly throughout the project. These challenges directly affect the reported effectiveness of psychosocial interventions. In this article, the authors describe the treatment fidelity plan developed by an interdisciplinary research team from recreational therapy and nursing for implementing recreational activities during a clinical trial funded by the National Institute of Nursing Research. The trial tests the efficacy of activities for responding to the behavioral symptoms of dementia. The authors report treatment fidelity strategies to allow comparison of their intervention with that of other studies, to improve effect size in similar studies, and to facilitate replication and translation of this work into clinical practice

Get your ACTivities together: New CMS regulations in long-term care.

Revised surveyor guidelines for ac- activities requirements in long-term care facilities became effective in June 2006. These guidelines have important programmatic, clinical, staff, and cost implications for gerontological nurses, administrators, and other facility staff. The investigative protocol used by surveyors is designed to determine whether a facility has provided a sufficient ongoing activities program that accommodates individual residents’ interests and enhances their physical, mental, and psychosocial well-being, according to each individual’s comprehensive assessment. The protocol details procedures that should be used for each resident in the sample to determine the facility’s compliance with the regulation
