Brothers and sisters sharing in the care of a parent with dementia.

Brothers' and sisters' experiences providing care to a parent with dementia differ, but little is known about how mixed-gender siblings share their caregiving responsibilities or how sharing affects their relationship. This study aimed to explore mixed-gender siblings processes for distributing caregiving tasks when caring for a parent with dementia and the impact of sharing care on their relationship. This descriptive qualitative study recruited fourteen English-speaking mixed-gender sibling pairs caring for a parent with dementia. Online open-ended surveys and individual semi-structured interviews were completed. Interviews and surveys explored division of caregiving responsibilities, conflict resolution, and the effects of sharing care on sibling relationships. Thematic analysis was used to analyze the qualitative data. Five themes were identified: goal of shared caregiving is to meet parents' needs, sisters often take the lead, practical issues affect sharing of caregiving activities, personal resources or skills affect division of responsibilities, and shared caregiving influences relationship quality. Understanding how siblings share caregiving responsibilities can inform the practices of healthcare professionals who care for people with dementia and their family caregivers.

Temporal masking of multidimensional tactual stimuli.

Experiments were performed to examine the temporal masking properties of multidimensional tactual stimulation patterns delivered to the left index finger. The stimuli consisted of fixed-frequency sinusoidal motions in the kinesthetic (2 or 4 Hz), midfrequency (30 Hz), and cutaneous (300 Hz) frequency ranges. Seven stimuli composed of one, two, or three spectral components were constructed at each of two signal durations (125 or 250 ms). Subjects identified target signals under three different masking paradigms: forward masking, backward masking, and sandwiched masking (in which the target is presented between two maskers). Target identification was studied as a function of interstimulus interval (ISI) in the range 0 to 640 ms. For both signal durations, percent-correct scores increased with ISI for each of the three masking paradigms. Scores with forward and backward masking were similar and significantly higher than scores obtained with sandwiched masking. Analyses of error trials revealed that subjects showed a tendency to respond, more often than chance, with the masker, the composite of the masker and target, or the combination of the target and a component of the masker. The current results are compared to those obtained in previous studies of tactual recognition masking with brief cutaneous spatial patterns. The results are also discussed in terms of estimates of information transfer (IT) and IT rate, are compared to previous studies with multidimensional tactual signals, and are related to research on the development of tactual aids for the deaf.
