Age-related changes in word retrieval vary by self-reported anxiety but not depression symptoms

Tip-of-the-tongue states (TOTs) are known to increase in frequency across adulthood, but there is wide variability in older adults’ TOT rates, suggesting that individual difference factors contribute to TOT incidence. We investigated the role of affect by examining the relationship between self-reported anxiety and depression symptoms and the frequency of TOTs during a laboratory task. Participants were young, middle-aged and older adults in a population-based sample of adults aged 18–87. Increased anxiety was associated with fewer TOTs for the middle-aged group but more TOTs for the older adult group. There was no relationship between anxiety and TOTs for younger adults and no relationships between depression symptoms and TOT incidence for any age group. We discuss our results in terms of attentional control theory, which provides an explanation of how age may affect the relationship between anxiety and TOTs.     

Specific effects of the Trier Social Stress Test on speech fluency in young and older adults

The notion that speech becomes less fluent during stressful speaking conditions has received little empirical test, and no research has tested this relationship in older adult participants. We analyzed speeches produced during the Trier Social Stress Test (TSST) or during a less stressful placebo (pTSST) version of the task. We measured young and older adults’ speech fillers (e.g., um), unfilled pauses (at least 1 s in duration), and other disfluencies (e.g., repetitions, repairs). Neither young nor older adult participants rated themselves as having greater stress in the TSST than pTSST condition, but behavioral effects were obtained. Participants in the TSST condition produced more mid-phrase speech fillers and unfilled pauses than participants in the pTSST condition. Young adults produced more unfilled pauses than older adults overall, and older adults produced more mid-phrase fillers than young adults. Critically, age group interacted with experimental condition, such that older speakers produced disproportionately more mid-phrase fillers than young adults in the TSST compared to the pTSST condition. In sum, the negative effects of the TSST on fluency were generally similar across age, but this specific age-related increase in mid-phrase fillers indicates that older adults’ word retrieval may have been particularly negatively affected. Findings are generally consistent with previous research and add to understanding of how factors internal to the speaker (i.e., demographic, personality, and cognitive variables) and factors external to the speaker (i.e., variables regarding the situation, context, or content of speech) combine to affect speech fluency.     

Positive aspects of voice-hearing: a qualitative metasynthesis

Voice-hearing occurs in clinical and non-clinical samples, and the role of spiritual and cultural frameworks of understanding for percipients has received increased attention. This review aimed to identify and synthesise the existing qualitative literature relating to positive aspects of voice-hearing experiences, and to make recommendations based on these findings for clinical practice and future research. Qualitative papers that included positive aspects of voice-hearing were identified by undertaking a systematic search of six electronic databases, resulting in 22 papers. The quality of each paper was assessed and the meta-ethnographic approach was used to extract and synthesise the data. Six themes were identified relating to voices providing safety and protection, guidance, creating psychological and emotional well-being, providing companionship, facilitating personal growth and development, and connecting hearers to religious or spiritual belief systems. The findings suggest positive aspects of voice-hearing that may have clinical and research implications.     

Improving visual spatial working memory in younger and older adults: effects of cross-modal cues

Spatially informative auditory and vibrotactile (cross-modal) cues can facilitate attention but little is known about how similar cues influence visual spatial working memory (WM) across the adult lifespan. We investigated the effects of cues (spatially informative or alerting pre-cues vs. no cues), cue modality (auditory vs. vibrotactile vs. visual), memory array size (four vs. six items), and maintenance delay (900 vs. 1800 ms) on visual spatial location WM recognition accuracy in younger adults (YA) and older adults (OA). We observed a significant interaction between spatially informative pre-cue type, array size, and delay. OA and YA benefitted equally from spatially informative pre-cues, suggesting that attentional orienting prior to WM encoding, regardless of cue modality, is preserved with age. Contrary to predictions, alerting pre-cues generally impaired performance in both age groups, suggesting that maintaining a vigilant state of arousal by facilitating the alerting attention system does not help visual spatial location WM.     

Interactions between stereotype threat,subjective aging,and memory in older adults

This study examined whether the effects of stereotype threat on memory and subjective age were moderated by positive age stereotypes and self-perceptions of aging among older adults. Perceived threat as a mechanism underlying these effects was also explored. Results showed that stereotype threat (high vs. low threat) did not affect the dependent variables. Moreover, self-perceptions of aging did not moderate the effect of stereotype threat on the dependent variables. However, for people with more positive age stereotypes, older people under highthreat perceived more threat than people under low threat. This could be explained by an effect of age stereotypes in the high-threat group: the more positive age stereotypes held by participants, the more they perceived threat, which in turn decreased their memory performance and made them feel mentally older. We hypothesized that age group identity is stronger in people with more positive age stereotypes, which increase perceived threat.     

More expertise for a better perspective: Task and strategy-driven adaptive neurofunctional reorganization for word production in high-performing older adults

The suggestion that neurofunctional reorganization may contribute to preserved language abilities is still emerging in aging studies. Some of these abilities, such as verbal fluency (VF), are not unitary but instead rely on different strategic processes that are differentially changed with age. Younger (n = 13) and older adults (n = 13) carried out an overt self-paced semantic and orthographic VF tasks within mixed fMRI design. Our results suggest that patterns of brain activation sustaining equivalent performances could be underpinned by different strategies facing brain changes during healthy aging. These main findings suggest that temporally mediated semantic clustering and frontally mediated orthographic switching were driven by evolutive neurofunctional resources in high-performing older adults. These age-related activation changes can appear to be compatible with the idea that unique neural patterns expressing distinctive cognitive strategies are necessary to support older adults’ performance on VF tasks.     

When I grow down – music,spirituality and memory loss: A performative lecture on aging

This article uses a postmodern methodology to set out a model of life which consists of a time of growing up and learning to speak, and of growing down when the power of speech and cognition gradually disintegrates. It describes how this was presented at a conference partly by means of drama (including movement and music) at the beginning and ending of a lecture which was designed to show the important role of music at the beginning and end of life. The centre of the presentation sets out the research into the role of music in personhood, wellbeing and health. It examines the role of music in connectedness, community and identity. There is much evidence for the relationship between music and health which is leading to the possibility of doctors prescribing music. The growth of community choirs has seen the growth of a musical aesthetic which values wellbeing highly. A phenomenography of the musical experience clarifies the relationship between music and wellbeing and the potentially transformative effects of the liminal space created by the four domains of musicking – Materials, Expression, Construction and Values. It also sets out a way of presenting research that engages the mind, body, emotions and spirituality of the audience.

奏响长者的“生命质量”凯歌

“健康老龄化”的探索中, 指标的定义至关重要。“生命质量”综合了生理、心理、社会、环境等多维度指标, 优于“预期寿命”、“健康预期寿命”等传统概念, 其定义在发展中被广为接受, 强调个体自评的主观性、可塑性和多维度。促进积极心理因素的干预是改善老年生命质量的有效路径。老龄化过程虽必然伴随生理系统衰退, 但心理系统积极参与, 仍能为年长者奏响生命质量的凯歌。     

Psychiatrists and community partners examine religion and spirituality

ABSTRACT

The commentary reflects on the definition of spirituality and religion and further implications for the practice of psychiatry. These include the possibilities to partner with spiritual and religious practitioners to support education and research, provide access to care for people with or at risk of mental ill health, and also consider how to the reduce the risks to the well-being of vulnerable people and families from some practices and settings. The World Psychiatric Association sees the possibilities for collaborating with its member societies and community partners including service users and family carers to develop resources on working with faith groups and spiritual healers in high- and low-income countries.
