Duet playing in dementia care: a new therapeutic music technology.

PURPOSE: Supporting the relational worlds of people living with dementia, especially the spousal dyad, is a growing focus in dementia care as is advancing the therapeutic use of music in dementia care. This paper describes a mixed-methods, multi-phase, iterative research study designed to develop the Music Memory Makers (MMM) Duet System, a novel therapeutic music technology, that allows non-musicians to play a personalized repertoire of songs arranged as duets. METHODS: Following a pilot phase to iteratively assess and refine the MMM Duet System for recreational and therapeutic purposes, multiple sources of data were used to investigate five older spousal dyads' experiences with the system, two couples living with dementia and three who were not. We assessed perceptions of task difficulty, joint agency, and enjoyment as well as therapeutic benefits associated with enhancing the spousal relationship and sense of couplehood. RESULTS: Findings suggest playing meaningful songs together is an enjoyable interactive activity that prompts musical reminiscence, involves joint agency, and supports relationship continuity within a relational, positive approach to dementia care. All couples mastered the task, none evaluated it as "very challenging," and positive couple interactions were evoked, commonly before and after playing the duets. CONCLUSIONS: The MMM Duet System is recommended for further research and development as an innovative way to support couples living with dementia with commercial implications, and as a new music technology suitable for use as a research tool.

Implications For RehabilitationMusic making is an engaging, rewarding activity promoting social bonding and wellbeing that with technology innovation, can be extended to non-musicians and people with differing skills, abilities, and preferences.The MMM Duet System is a promising new music technology that supports the relationship of people living with dementia and their spousal caregivers by encouraging relationship continuity and sense of couplehood. Supporting caregivers enables people with dementia to remain longer in their homes and communities.Practical suggestions are offered to develop music technology suitable for use by older adults and people living with dementia, e.g., involving participants who live with dementia, assembling interdisciplinary research teams, adopting iterative, participant-focused approach.

Digital adaptations to arts programme delivery for people living with dementia in response to the COVID-19 pandemic.

BACKGROUND: Learning from the challenges and successes of online arts delivery during the pandemic is crucially important for considering long-term sustainable solutions that enable people living with dementia to remotely participate in meaningful activities. METHODS: Twenty-eight arts workers responded to an online survey exploring i) the meaning of face-to-face arts activities that were replicated online, ii) perceived motivations to attend, iii) successes and challenges in adapting arts for online/socially distanced setting. RESULTS: Responses described arts giving structure and purpose to people living with dementia and their carers, a sense of community, and a way to reduce physical isolation. Success on digital delivery of arts depended on how inclusive practices were in relation to different abilities, technology experience and support levels. CONCLUSIONS: Despite challenges, the range of interactions across activities demonstrated various ways for people living with dementia to make a contribution, feeding into the feelings of purpose and belonging in the online/digital community.

Not just in sync: Relations between partners' actions influence the sense of joint agency during joint action.

When people perform joint actions together, they often experience a sense of joint agency ("we did that together"). The current study investigated whether relations between partners' actions within joint actions that require precise interpersonal synchrony influence joint agency, above and beyond the degree of synchrony partners achieve. We employed a mixed-methods approach that combined a quantitative experiment with a qualitative analysis of post-experiment interviews. Partners produced synchronized tone sequences that comprised either constant pitch sequences (simple temporal alignment between partners' actions) or musical duets (complex metrical and harmonic relations between partners' actions). Participants reported stronger joint agency for duets than constant pitches, when comparing trials with equally good synchronization. Post-experiment interviews revealed that joint agency was also influenced by participants' knowledge of the music and their perceptions of task performance, difficulty, and enjoyability. These findings further our understanding of joint agency for joint actions that require precise interpersonal synchrony.

Alpha oscillations related to self-other integration and distinction during live orchestral performance: A naturalistic case study.

Ensemble music performance requires musicians to achieve precise interpersonal coordination while maintaining autonomous control over their own actions. To do so, musicians dynamically shift between integrating other performers' actions into their own action plans and maintaining a distinction between their own and others' actions. Research in laboratory settings has shown that this dynamic process of self-other integration and distinction is indexed by sensorimotor alpha oscillations. The purpose of the current descriptive case study was to examine oscillations related to self-other integration and distinction in a naturalistic performance context. We measured alpha activity from four violinists during a concert hall performance of a 60-musician orchestra. We selected a musical piece from the orchestra's repertoire and, before analyzing alpha activity, performed a score analysis to divide the piece into sections that were expected to strongly promote self-other integration and distinction. In line with previous laboratory findings, performers showed suppressed and enhanced alpha activity during musical sections that promoted self-other integration and distinction, respectively. The current study thus provides preliminary evidence that findings from carefully controlled laboratory experiments generalize to complex real-world performance. Its findings also suggest directions for future research and potential applications of interest to musicians, music educators, and music therapists.

The use of technology for arts-based activities in older adults living with mild cognitive impairment or dementia: A scoping review.

For older adults living with mild cognitive impairment or dementia, creative arts-based activities can offer many benefits from enjoyment as leisure/recreation to an avenue to maintain cognitive, social and emotional wellbeing. With growing interest and recognition that technology could have potential to assist in delivering these activities in more accessible and personalised ways, a scoping review was undertaken to systematically examine the scientific literature for technology-assisted creative arts activities for older adults living with dementia. We searched PubMed, PsychINFO, Web of Science, Scopus and ACM Digital Library databases using keywords centering on population with dementia, an intervention using technology, and a context of creative arts, with no restrictions on the type of outcome measured. We retrieved 3739 records, with an additional 22 from hand-searching. 51 full-text articles met the inclusion and exclusion criteria. Findings of the review indicate technologies principally being designed for music activities (listening, and music-making), as well as storytelling and visual arts. The majority of devices were custom-made, with studies mainly reporting on validating the success of the device/intervention. This suggests most work in the field is currently at prototyping stage, although a few devices are now commercially available. Recommendations for future research includes involvement of participants reporting on their previous experiences in the arts and how this influences co-design choices, and inclusion of different severities of dementia in the participant/co-design group. Furthering device development past prototyping stage as well as collaboration between teams would enable comparisons to be made across different types of devices used for the same activity, and comparisons across arts-based activities that could lead to cross-disciplinary outcomes for the design of creative arts-based assistive technologies.

A compact cold-atom interferometer with a high data-rate grating magneto-optical trap and a photonic-integrated-circuit-compatible laser system.

The extreme miniaturization of a cold-atom interferometer accelerometer requires the development of novel technologies and architectures for the interferometer subsystems. Here, we describe several component technologies and a laser system architecture to enable a path to such miniaturization. We developed a custom, compact titanium vacuum package containing a microfabricated grating chip for a tetrahedral grating magneto-optical trap (GMOT) using a single cooling beam. In addition, we designed a multi-channel photonic-integrated-circuit-compatible laser system implemented with a single seed laser and single sideband modulators in a time-multiplexed manner, reducing the number of optical channels connected to the sensor head. In a compact sensor head containing the vacuum package, sub-Doppler cooling in the GMOT produces 15 µK temperatures, and the GMOT can operate at a 20 Hz data rate. We validated the atomic coherence with Ramsey interferometry using microwave spectroscopy, then demonstrated a light-pulse atom interferometer in a gravimeter configuration for a 10 Hz measurement data rate and T = 0-4.5 ms interrogation time, resulting in Δg/g = 2.0 × 10-6. This work represents a significant step towards deployable cold-atom inertial sensors under large amplitude motional dynamics.

Application of a self-injection locked cyan laser for Barium ion cooling and spectroscopy.

Compact, high power lasers with narrow linewidth are important tools for the manipulation of quantum systems. We demonstrate a compact, self-injection locked, Fabry-Perot semiconductor laser diode with high output power at 493 nm. A high quality factor magnesium fluoride whispering gallery mode resonator enables both high passive stability and 1 kHz instantaneous linewidth. We use this laser for laser-cooling, in-situ isotope purifcation, and probing barium atomic ions confined in a radio-frequency ion trap. The results here demonstrate the suitability of these lasers in trapped ion quantum information processing and for probing weak coherent optical transitions.

Hardware and software improvements to a low-cost horizontal parallax holographic video monitor.

Displays capable of true holographic video have been prohibitively expensive and difficult to build. With this paper, we present a suite of modularized hardware components and software tools needed to build a HoloMonitor with basic "hacker-space" equipment, highlighting improvements that have enabled the total materials cost to fall to $820, well below that of other holographic displays. It is our hope that the current level of simplicity, development, design flexibility, and documentation will enable the lay engineer, programmer, and scientist to relatively easily replicate, modify, and build upon our designs, bringing true holographic video to the masses.

Spectroscopy of a Synthetic Trapped Ion Qubit.

^{133}Ba^{+} has been identified as an attractive ion for quantum information processing due to the unique combination of its spin-1/2 nucleus and visible wavelength electronic transitions. Using a microgram source of radioactive material, we trap and laser cool the synthetic A=133 radioisotope of barium II in a radio-frequency ion trap. Using the same, single trapped atom, we measure the isotope shifts and hyperfine structure of the 6^{2}P_{1/2}↔6^{2}S_{1/2} and 6^{2}P_{1/2}↔5^{2}D_{3/2} electronic transitions that are needed for laser cooling, state preparation, and state detection of the clock-state hyperfine and optical qubits. We also report the 6^{2}P_{1/2}↔5^{2}D_{3/2} electronic transition isotope shift for the rare A=130 and 132 barium nuclides, completing the spectroscopic characterization necessary for laser cooling all long-lived barium II isotopes.

Adolescent Motivations to Engage in Pro-Social Behaviors and Abstain From Health-Risk Behaviors: A Self-Determination Theory Approach.

The present study used self-determination theory to examine adolescents' motivations to engage in charitable donating and community volunteering and to abstain from sexual intercourse and marijuana use. The sample consisted of 419 late adolescents recruited from across the country through an online survey panel. Participants completed online measures of motivations to engage in donating and volunteering, motivations to abstain from sex and marijuana, and single-item indexes of the four behaviors. Variable-centered analyses (correlation and regression) found evidence for a general motivational factor, motivational specificity by behavioral domain (positive and negative behaviors), motivational specificity by particular behavior (charitable donating, volunteering, sexual risk-taking, and marijuana use), and a stronger relative role for autonomous motivations than controlled motivations. Person-centered analyses (cluster analysis) found four motivation profiles (low motivation, medium motivation, high motivation, and mixed motivation) for all four behaviors and suggested that level of autonomous motivation was a key factor differentiating the groups on levels of behavior. The findings suggest different levels of motivational specificity and highlight the importance of autonomous motivations in predicting behaviors as compared to controlled motivations. Further, similar patterns were found for motivations to engage and to abstain.
