Playing with delayed auditory feedback

2009

This paper presents a study where the effect of a delayed acoustic feedback is researched with 10 professional musicians performing four different pieces of piano music. The influence of a delayed auditory feedback on the performance is quantified using both MIDI information and the measurement of the movement of the upper body of the pianists. Four conditions were examined namely: a normal piano performance, a performance without acoustic feedback and two conditions with a delayed acoustic feedback of 300ms and 200ms respectively. The analysis of the MIDI data shows a significant increase in both the velocity of the keystrokes and the duration of the performance in the delayed conditions. …

Sociolinguistic upsets and people of color in social media performances

2022

Abstract Particularly since the refugee “reception crisis” in 2015, Finland has started transforming into a more diverse and multicultural society. These societal changes have also been accompanied by sociolinguistic change, as well as language ideological debates and tensions, often manifesting in explicitly racist and xenophobic bursts of upset. In this article, our focus is on social media as a space where such societal and sociolinguistic upsets are articulated and re-worked. Drawing on recent sociolinguistic and discourse analytic work on transformative and critical popular cultural practices in social media, and studies on rap and belonging, we discuss how, in a mediatized society suc…

Automatic auditory and somatosensory brain responses in relation to cognitive abilities and physical fitness in older adults

2017

AbstractIn normal ageing, structural and functional changes in the brain lead to an altered processing of sensory stimuli and to changes in cognitive functions. The link between changes in sensory processing and cognition is not well understood, but physical fitness is suggested to be beneficial for both. We recorded event-related potentials to somatosensory and auditory stimuli in a passive change detection paradigm from 81 older and 38 young women and investigated their associations with cognitive performance. In older adults also associations to physical fitness were studied. The somatosensory mismatch response was attenuated in older adults and it associated with executive functions. So…

How physical activity, fitness, and motor skills contribute to math performance: Working memory as a mediating factor

2021

Purpose The purpose of this study was to examine whether physical activity, fitness and motor skills have indirect association with math performance via cognitive outcomes and if so, through which aspects of cognition? Methods This study comprised 311 6th–9th grade adolescents (12–17y [M age=14.0y], 59% girls) from seven schools throughout Finland in 2015. Math performance was measured via a teacher-rated math achievement and the Basic Arithmetic test. Cognitive functions were measured by broad cognitive test battery. Physical activity was assessed with a self-reported questionnaire and a hip-worn accelerometer. Aerobic fitness was estimated using a maximal 20-m shuttle run test, muscular f…

Relationship between cognitive performance and mobility over the life course

2018

We studied cross-sectional, longitudinal and temporal associations between executive function and life-space mobility in old age. We assessed the association between intellectual ability in early adulthood and physical functioning in old age, and the association between early life motor development and cognitive performance in early old age. The participants of the first dataset were 157 persons aged 76-91 y who were followed up for two years as part of the Life-Space Mobility in Old Age study, and who took part in measurements on executive function (EF) implemented with the Trail Making Test and Life-Space Assessment. The second dataset comprised persons from the Helsinki Birth Cohort Stud…

Returning to Work after Stroke: Associations with Cognitive Performance, Motivation, Perceived Working Ability and Barriers.

2022

Objective: To investigate post-stroke return-to-work and its associations with cognitive performance, motivation, perceived working ability, and self-perceived barriers to returning to work.Design: Prospective cohort study of a clinical sample.Subjects and methods: Participants were 77 stroke patients younger than age 69 years. Assessment included a cognitive screening method for stroke patients (CoMet), a questionnaire regarding work-related matters, and a question regarding motivation to return to work. A predictive model of return-to-work was built, and how participants managed in their working life was examined.Results: Cognitive performance was significantly connected with returning to…

Secular rise in economically valuable personality traits

2017

Although trends in many physical characteristics and cognitive capabilities of modern humans are well-documented, less is known about how personality traits have evolved over time. We analyze data from a standardized personality test administered to 79% of Finnish men born between 1962 and 1976 (n = 419,523) and find steady increases in personality traits that predict higher income in later life. The magnitudes of these trends are similar to the simultaneous increase in cognitive abilities, at 0.2-0.6 SD during the 15-y window. When anchored to earnings, the change in personality traits amounts to a 12% increase. Both personality and cognitive ability have consistent associations with famil…

Physical activity and sedentary time in relation to academic achievement in children

2017

Objectives To investigate the independent and combined associations of objectively measured moderate-to-vigorous physical activity (MVPA) and sedentary time (ST) with reading and arithmetic skills. Design Cross-sectional/prospective. Methods Participants were 89 boys and 69 girls aged 6–8 years. MVPA and ST were measured using a combined heart rate and movement sensor and body fat percentage by dual-energy X-ray absorptiometry in Grade 1. Reading fluency, reading comprehension, and arithmetic skills were assessed using standardized tests in Grades 1–3. The data were analyzed using linear regression analyses and analyses of covariance with repeated measures. Results In boys, MVPA was directl…

The combined effect of lower extremity function and cognitive performance on perceived walking ability among older people : a 2-year follow-up study

2018

Background We studied the combined effects of cognitive performance and lower extremity function on self-reported walking modifications and walking difficulty and on self-reported walking difficulty incidence over a 2-year follow-up. Methods A total of 848 community-dwelling older people aged 75-90 years participated at baseline, 816 at the 1-year follow-up, and 761 at the 2-year follow-up. Baseline lower extremity function was measured with the Short Physical Performance Battery (<10 vs. ≥10) and cognitive performance with the Mini-Mental State Examination (<24 vs. ≥24). Difficulty in walking 2 km was self-reported and categorized into no difficulties, no difficulties but walking modificat…
