The Emerging Neuroscience of Intrinsic Motivation: A New Frontier in Self-Determination Research.

Abstract: Intrinsic motivation refers to people's spontaneous tendencies to be curious and interested, to seek out challenges and to exercise and develop their skills and knowledge, even in the absence of operationally separable rewards. Over the past four decades, experimental and field research guided by self-determination theory (SDT; Ryan and Deci, 2017) has found intrinsic motivation to predict enhanced learning, performance, creativity, optimal development and psychological wellness. Only recently, however, have studies begun to examine the neurobiological substrates of intrinsic motivation. In the present article, we trace the history of intrinsic motivation research, compare and contrast intrinsic motivation to closely related topics (flow, curiosity, trait plasticity), link intrinsic motivation to key findings in the comparative affective neurosciences, and review burgeoning neuroscience research on intrinsic motivation. We review converging evidence suggesting that intrinsically motivated exploratory and mastery behaviors are phylogenetically ancient tendencies that are subserved by dopaminergic systems. Studies also suggest that intrinsic motivation is associated with patterns of activity across large-scale neural networks, namely, those that support salience detection, attentional control and self-referential cognition. We suggest novel research directions and offer recommendations for the application of neuroscience methods in the study of intrinsic motivation.

Hearing Their Voice: A Systematic Review of Dementia Family Caregivers’ Needs

Abstract: Purpose The number of Australians living with dementia is expected to increase from currently 332,000 to 900,000 by 2050. Around 200,000 unpaid caregivers are caring for community-dwelling people living with dementia, and therefore, supporting the caregivers' needs is of paramount importance. The aim of this systematic review was to understand the perceived needs of immediate family caregivers of community-dwelling older adults with dementia. Design and methods We examined qualitative studies that reported on the self-perceived needs of partner and/or offspring caregivers who were caring for community-dwelling older adults with dementia. Results Two themes were developed from 12 studies: caregiver needs related to the management of older people with dementia and caregivers' personal needs. The first theme further included four subthemes: information and knowledge needs; activities of daily living, instrumental activities of daily living and Behavioural and Psychological Symptoms of Dementia support needs; formal care support needs; and informal care support needs. The second theme consisted of two subthemes: the need to address caregivers' physical and psychological health and the need to manage caregivers' own lives. Implications The findings have important implications for the development of interventions that comprehensively address caregivers' individual needs. Caregivers' unmet needs highlight key areas for improvement in policy and service provision. The findings demonstrate the need for more rigorous qualitative studies exploring the perceived needs of partner and offspring caregivers respectively. Furthermore, examining the underlying relationships between different caregiver needs is warranted.

Nursing and aggression in the workplace: a systematic review

Abstract: Personal experiences of aggression or violence in the workplace lead to serious consequences for nurses, their patients, patient care and the organisation as a whole. While there is a plethora of research on this topic, no review is available that identifies types of aggression encountered, individuals perceived to be most at risk and coping strategies for victims. The aim of this systematic review was to examine occupational anxiety related to actual aggression in the workplace for nurses. Databases (MEDLINE, CINAHL and PsycINFO) were searched, resulting in 1543 titles and abstracts. After removal of duplicates and non-relevant titles, 137 papers were read in full. Physical aggression was found to be most frequent in mental health, nursing homes and emergency departments while verbal aggression was more commonly experienced by general nurses. Nurses exposed to verbal or physical abuse often experienced a negative psychological impact post incident.
