The NA62 experiment at CERN, configured in beam-dump mode, has searched for dark photon decays in flight to electron-positron pairs using a sample of 1.4×10^{17} protons on dump collected in 2021. No evidence for a dark photon signal is observed.

Feeling Younger on Active Summer Days? On the Interplay of Behavioral and Environmental Factors With Day-to-Day Variability in Subjective Age.

Background And Objectives: Subjective age, that is, how old people feel in relation to their chronological age, has mostly been investigated from a macro-longitudinal, lifespan point of view and in relation to major developmental outcomes. Recent evidence also shows considerable intraindividual variations in micro-longitudinal studies as well as relations to everyday psychological correlates such as stress or affect, but findings on the interplay with physical activity or sleep as behavioral factors and environmental factors such as weather conditions are scarce.

Research Design And Methods: We examined data from 80 recently retired individuals aged 59-76 years ( = 67.

Do early midlife work characteristics predict 20-year change in control beliefs?

Previous research showed the importance of control beliefs for many life outcomes. The present study examines associations between subjectively perceived work environment and objectively measured work activities at the beginning of midlife as a central developmental phase in the context of work, with control beliefs across the subsequent 20 years. We analyzed four-wave longitudinal data from = 374 participants (born 1950-1952; baseline = 44 years, = 1; 44% women) from the Interdisciplinary Longitudinal Study of Adult Development and Aging within a structural equation modeling framework.

Assessing students with dyslexia and other reading difficulties through multiple diagnostic assessments.

This article aims to assist practitioners in understanding dyslexia and other reading difficulties and assessing students' learning needs. We describe the essential components of language and literacy, universal screening, diagnostic assessments, curriculum-based measurement and eligibility determination. We then introduce four diagnostic assessments as examples, including norm-referenced assessments (i.

Psychometric Properties and Measurement Invariance of the Awareness of Age-Related Change Short Form in Older Adult Samples From Taiwan and Germany.

Background And Objectives: This study examined the psychometric properties and measurement invariance of the 10-item Awareness of Age-Related Change Short Form (AARC-SF) questionnaire in a Chinese-speaking sample of older adults in Taiwan.

Research Design And Methods: Data from 292 participants (Mage = 77.64 years) in the Healthy Aging Longitudinal Study in Taiwan cohort were used for Study 1, whereas data from young-old adult samples in Germany were used for Study 2.

Successful Aging and Subjective Aging: Toward a Framework to Research a Neglected Connection.

Research related to subjective aging, which describes how individuals perceive, interpret and evaluate their own aging, has substantially grown in the past two decades. Evidence from longitudinal studies shows that subjective aging predicts health, quality of life, and functioning in later life. However, the existing literature on successful aging has mostly neglected the role of subjective aging.

Altered neural anticipation of reward and loss but not receipt in adolescents with obsessive-compulsive disorder.

Background: Obsessive-compulsive disorder (OCD) is characterized by persistent, unwanted thoughts and repetitive actions. Such repetitive thoughts and/or behaviors may be reinforced either by reducing anxiety or by avoiding a potential threat or harm, and thus may be rewarding to the individual. The possible involvement of the reward system in the symptomatology of OCD is supported by studies showing altered reward processing in reward-related regions, such as the ventral striatum (VS) and the orbitofrontal cortex (OFC), in adults with OCD.

Differential Item Functioning Along the Old Age Continuum: Contrasting Chronological Age With Contextual Variables in the Assessment of Gains and Losses Across Advanced Old Age.

Objectives: The fourth age is considered a life stage with a high likelihood of age-related losses. However, very old age extends over decades, and little is known about how transitions that may happen during this age period (e.g.

Self-perceptions of aging: A conceptual and empirical overview.

This article defines self-perceptions of aging (SPA) as individuals' perceptions, expectations, and experiences regarding their own process of growing old(er). As such, SPA are considered a critically important element of the aging self. Furthermore, the authors present a heuristic model that positions adults' SPA within a lifespan developmental and cultural-societal context and elaborates distal and proximal antecedents, process modes, and developmental outcomes.

"If this is what it means to be old…": a mixed methods study on the effects of age simulation on views on aging and perceptions of age-related impairments.

Age simulation suits are a promising tool to increase empathy and to promote positive attitudes toward older adults. However, studies have largely focused on (young) healthcare professionals, are probably biased by social desirability, and have not addressed participants' views of the aging process triggered by the simulation. The current work combines two studies addressing effects of aging suits on both general and personal views on aging among heterogeneous samples, and exploring spontaneous associations during the simulation.

Improved Visualization and Quantification of Net Water Uptake in Recent Small Subcortical Infarcts in the Thalamus Using Computed Tomography.

Diagnosing recent small subcortical infarcts (RSSIs) via early computed tomography (CT) remains challenging. This study aimed to assess CT attenuation values (Hounsfield Units (HU)) and net water uptake (NWU) in RSSI and explore a postprocessing algorithm's potential to enhance thalamic RSSI detection. We examined non-contrast CT (NCCT) data from patients with confirmed thalamic RSSI on diffusion-weighted magnetic resonance imaging (DW-MRI) between January 2010 and October 2017.

Differences in self-perceptions of aging across the adult lifespan: The sample case of awareness of age-related gains and losses.

Rooted in the premises of lifespan developmental theory, the concept of awareness of age-related change (AARC) posits that growing older comes with both experiences of gains and losses across different behavioral domains. However, little is known about how age-related change is perceived across the entire adult lifespan, provided that respective measures can be validly compared. Further, few studies have adopted an approach that examines gains and losses simultaneously to study a potential shift in the ratio of perceived age-related gains and losses from adolescence to advanced old age.

Levels of awareness of age-related gains and losses throughout adulthood and their developmental correlates.

Views of aging predict key developmental outcomes. Less is known, however, about the consequences of constellations of domain-specific perceived gains and losses across the full adult lifespan. First, we explored levels of awareness of age-related gains (AARC-gains) and losses (AARC-losses) in five behavioral domains across adulthood.

Consequences of contact restrictions for long-term care residents during the first months of COVID-19 pandemic: a scoping review.

During the early stages of the COVID-19 pandemic, stringent measures were implemented in most countries to limit social contact between residents of long-term care facilities (LTCF) and visitors. The objective of this scoping review was to identify and map evidence of direct and indirect consequences of contact restrictions, guided by three conceptual perspectives: (1) stress and learned helplessness (i.e.

Long-term aging trajectories of the accumulation of disease burden as predictors of daily affect dynamics and stressor reactivity.

Multiple-timescale studies provide new opportunities to examine how developmental processes that evolve at different cadences are intertwined. Developmental theories of emotion regulation suggest that the long-term, slowly evolving age-related accumulation of disease burden should shape short-term, faster evolving (daily) affective experiences. To empirically examine this proposition, we combined data from 123 old adults (65-69 years, 47% women) and 32 very old adults (85-88 years, 59% women) who provided 20 + year within-person longitudinal data on physician-rated morbidity and subsequently also completed repeated daily-life assessments of stress and affect six times a day over 7 consecutive days as they were going about their daily-life routines.

Testing Bidirectionality in Associations of Awareness of Age-Related Gains and Losses With Physical, Mental, and Cognitive Functioning Across 1 Year: The Role of Age.

Objectives: The bidirectionality between self-perceptions of aging and health-related outcomes may depend on age group. Therefore, we tested such bidirectionality among individuals in late midlife (50-64 years), young-old age (65-74 years), and old-old age (75+ years), taking advantage of the construct of Awareness of Age-Related Change (AARC) and its 2-dimensionality in terms of AARC-gains and AARC-losses. Various conceptualizations of physical, mental, and cognitive functioning were used as outcomes.

Aging in 10 Minutes: Do Age Simulation Suits Mimic Physical Decline in Old Age? Comparing Experimental Data with Established Reference Data.

Introduction: Age simulation suits are increasingly used in health care education. However, empirical evidence that quantifies the simulated performance losses in established geriatric tests and compares those declines with reference data of older adults is scarce.

Methods: In a standardized lab setting, we compared performance of  = 61 participants (46 middle-aged, 15 young adults) with and without age simulation suit, for example in the Timed Up and Go Test (+dual task), Short Physical Performance Battery, grip strength, and 30-Second-Chair- Standing Test.

Triangulating brain alterations in anorexia nervosa: a multimodal investigation of magnetic resonance spectroscopy, morphometry and blood-based biomarkers.

The acute state of anorexia nervosa (AN) is associated with widespread reductions in cortical gray matter (GM) thickness and white matter (WM) volume, suspected changes in myelin content and elevated levels of the neuronal damage marker neurofilament light (NF-L), but the underlying mechanisms remain largely unclear. To gain a deeper understanding of brain changes in AN, we applied a multimodal approach combining advanced neuroimaging methods with analysis of blood-derived biomarkers. In addition to standard measures of cortical GM thickness and WM volume, we analyzed tissue-specific profiles of brain metabolites using multivoxel proton magnetic resonance spectroscopy, T1 relaxation time as a proxy of myelin content leveraging advanced quantitative MRI methods and serum NF-L concentrations in a sample of 30 female, predominately adolescent patients with AN and 30 age-matched female healthy control participants.

Three facets of emotion regulation in old and very old age: Strategy use, effectiveness, and variability.

The ability to regulate emotions in stressful situations is an important building block for high well-being across the lifespan. Yet, very little is known about how old and very old adults regulate their emotions. In this study, 123 young old adults ( = 67.
