Reminiscence Therapy and Music With Older Adults: A Descriptive Study Investigating the Current Views and Practices of Australian Aged Care Providers and Volunteers.

Reminiscence therapy and music are often used to improve the wellbeing of older people; however, we do not know how these interventions are used in practice. This study explored how those working with older people view and use verbal Reminiscence Therapy (VRT) and Music-assisted Reminiscence Therapy (MRT). A total of 110 participants who worked or volunteered with older people in Australia were surveyed in this descriptive, mixed-method study. VRT and MRT were frequently and spontaneously used to respond to the varied needs of older adults. VRT and MRT lead to reported positive outcomes including better care practices, positive affect and mood, and improved social connections. MRT was used as a compensatory strategy when traditional VRT was not possible. This study describes the current practices of VRT and MRT, and an overview of how reminiscence-based approaches are used in Australia to address the health and wellbeing of older people.

Planting the SEED: A model to describe the functions of music in reminiscence therapy.

Music-assisted reminiscence therapy involves the use of music, in any form, to prompt and augment the recollection of autobiographical memories and therapeutic reframing of the meaning of one's life and experiences. The functions of music in reminiscence therapy remains unclear. Drawing on interdisciplinary research in music therapy, psychology, sociology, gerontology, and neuroscience, this paper proposes a theoretical model for understanding the multiple functions of music when used in reminiscence therapy, and describes how music-assisted reminiscence therapy might be used to improve the wellbeing of older people. The SEED model proposes that music, when used together with reminiscence interventions, helps to: 1) summon autobiographical memories; 2) evoke strong emotional reactions; 3) elicit physiological responses; and 4) define identity. Evidence for the four proposed functions of music in reminiscence interventions is presented. The SEED model expands on previous research and theory on music and reminiscence, neural and cognitive processing, and the therapeutic use of music. The SEED model maps the benefits and indicators for the use of music in reminiscence therapy and provides a blueprint for research to test the purported benefits of using music to enhance reminiscence therapy.

A high-density EEG investigation into steady state binaural beat stimulation.

Binaural beats are an auditory phenomenon that has been suggested to alter physiological and cognitive processes including vigilance and brainwave entrainment. Some personality traits measured by the NEO Five Factor Model have been found to alter entrainment using pulsing light stimuli, but as yet no studies have examined if this occurs using steady state presentation of binaural beats for a relatively short presentation of two minutes. This study aimed to examine if binaural beat stimulation altered vigilance or cortical frequencies and if personality traits were involved. Thirty-one participants were played binaural beat stimuli designed to elicit a response at either the Theta (7 Hz) or Beta (16 Hz) frequency bands while undertaking a zero-back vigilance task. EEG was recorded from a high-density electrode cap. No significant differences were found in vigilance or cortical frequency power during binaural beat stimulation compared to a white noise control period. Furthermore, no significant relationships were detected between the above and the Big Five personality traits. This suggests a short presentation of steady state binaural beats are not sufficient to alter vigilance or entrain cortical frequencies at the two bands examined and that certain personality traits were not more susceptible than others.

Acute neurocognitive effects of epigallocatechin gallate (EGCG).

Green tea is reported to have wide ranging beneficial health outcomes across epidemiological studies, which have been attributed to its flavonoid content. We investigated whether the flavonoid epigallocatechin gallate (EGCG) modulates brain activity and self-reported mood in a double-blind, placebo controlled crossover study. Participants completed baseline assessments of cognitive and cardiovascular functioning, mood and a resting state electroencephalogram (EEG) before and then 120 min following administration of 300 mg EGCG or matched placebo. EGCG administration was associated with a significant overall increase in alpha, beta and theta activity, also reflected in overall EEG activity, more dominant in midline frontal and central regions, specifically in the frontal gyrus and medial frontal gyrus. In comparison to placebo the EGCG treatment also increased self-rated calmness and reduced self rated stress. This pattern of results suggests that participants in the EGCG condition may have been in a more relaxed and attentive state after consuming EGCG. This is in keeping with the widespread consumption of green tea for its purported relaxing/refreshing properties. The modulation of brain function due to EGCG is deserving of further controlled human studies.

EEG correlates of virtual reality hypnosis.

The study investigated hypnosis-related electroencephalographic (EEG) coherence and power spectra changes in high and low hypnotizables (Stanford Hypnotic Clinical Scale) induced by a virtual reality hypnosis (VRH) induction system. In this study, the EEG from 17 participants (Mean age = 21.35, SD = 1.58) were compared based on their hypnotizability score. The EEG recording associated with a 2-minute, eyes-closed baseline state was compared to the EEG during a hypnosis-related state. This novel induction system was able to produce EEG findings consistent with previous hypnosis literature. Interactions of significance were found with EEG beta coherence. The high susceptibility group (n = 7) showed decreased coherence, while the low susceptibility group (n = 10) demonstrated an increase in coherence between medial frontal and lateral left prefrontal sites. Methodological and efficacy issues are discussed.
