New fast mismatch negativity paradigm for determining the neural prerequisites for musical ability.
2011
Studies have consistently shown that the mismatch negativity (MMN) for different auditory features correlates with musical skills, and that this effect is more pronounced for stimuli integrated in complex musical contexts. Hence, the MMN can potentially be used for determining the development of auditory skills and musical expertise. MMN paradigms, however, are typically very long in duration, and far from sounding musical. Therefore, we developed a novel multi-feature MMN paradigm with 6 different deviant types integrated in a complex musical context of no more than 20 min in duration. We found significant MMNs for all 6 deviant types. Hence, this short objective measure can putatively be …
Informal musical activities are linked to auditory discrimination and attention in 2-3-year-old children: an event-related potential study
2012
The relation between informal musical activities at home and electrophysiological indices of neural auditory change detection was investigated in 2-3-year-old children. Auditory event-related potentials were recorded in a multi-feature paradigm that included frequency, duration, intensity, direction, gap deviants and attention-catching novel sounds. Correlations were calculated between these responses and the amount of musical activity at home (i.e. musical play by the child and parental singing) reported by the parents. A higher overall amount of informal musical activity was associated with larger P3as elicited by the gap and duration deviants, and smaller late discriminative negativity r…
Predictive error detection in pianists: A combined ERP and motion capture study
2013
Performing a piece of music involves the interplay of several cognitive and motor processes and requires extensive training to achieve a high skill level. However, even professional musicians commit errors occasionally. Previous event-related potential (ERP) studies have investigated the neurophysiological correlates of pitch errors during piano performance, and reported pre-error negativity already occurring approximately 70–100 ms before the error had been committed and audible. It was assumed that this pre-error negativity reflects predictive control processes that compare predicted consequences with actual consequences of one's own actions. However, in previous investigations, correct a…
Reading and math abilities of Finnish school beginners born very preterm or with very low birth weight
2017
Reading and math skills of preterm born (birth weight 1500 g or gestational age:532 weeks) children and full term (FT) children were compared during the first weeks of grade 1. The participants were 194 preterm born and 175 FT children born between 2001 and 2006. There were more precocious readers among FT than among preterm students, but even the latter performed close to the national norm. FT and preterm group differences among non-readers were minor with only rapid naming showing a robust difference. Math performance showed a stable difference in favor of FT students and the difference was sustained in the full-scale IQcontrol. Major brain pathology increased the likelihood of poor schol…
Polymorphisms in DCDC2 and S100B associate with developmental dyslexia
2015
Genetic studies of complex traits have become increasingly successful as progress is made in next-generation sequencing. We aimed at discovering single nucleotide variation present in known and new candidate genes for developmental dyslexia: CYP19A1, DCDC2, DIP2A, DYX1C1, GCFC2 (also known as C2orf3), KIAA0319, MRPL19, PCNT, PRMT2, ROBO1 and S100B. We used next-generation sequencing to identify single-nucleotide polymorphisms in the exons of these 11 genes in pools of 100 DNA samples of Finnish individuals with developmental dyslexia. Subsequent individual genotyping of those 100 individuals, and additional cases and controls from the Finnish and German populations, validated 92 out of 111 …
Paper vs. Pixel: Can We Use a Pen-and-Paper Method to Measure Athletes' Implicit Doping Attitude?
2017
Doping attitude is an individual’s subjective evaluation (e.g., good or bad, useful or useless) toward the use of prohibited performance-enhancing substances or methods in sports. Research on doping attitude has traditionally relied on self-report questionnaire methods to measure the construct (Ntoumanis et al., 2014; Chan et al., 2015). However, as doping in sport is illegal (World AntiDoping Agency, 2015) and perceived as socially unacceptable, athletes who hold positive attitudes toward doping are less likely to reveal them to others. As a result explicit measures of doping attitude are susceptible to potential bias as athletes may respond in a socially desirable fashion (Petróczi and Ai…
The buffering effect of coping strategies in the relationship between job insecurity and employee well-being
2012
The modern labour market features job insecurity (JI) as an unavoidable stressor. This study considers the influence of personal coping strategies by combining the conservation of resources with spillover theory. Do coping strategies buffer the negative effects of JI on well-being (work engagement, marital satisfaction and emotional energy at work and home)? A cybernetic coping scale distinguishes five coping strategies and a survey of 2764 Finnish employees reveals that changing the situation and symptom reduction buffer the negative effect of JI on emotional energy at work and home, respectively. Devaluation and accommodation have buffering tendencies in relation to work engagement and m…
The role of job resources in the relation between perceived employability and turnover intention: A prospective two-sample study
2011
Abstract We hypothesize that the relationship between perceived employability (PE) and turnover intention is stronger when job resources (job control, social support from the supervisor and colleagues) are low. Results from a prospective study one year apart were similar in samples of Finnish university ( N = 1314) and hospital workers ( N = 308). The interaction between PE and job control related significantly to turnover intention at Time 2 in both samples, and in the hospital sample also when controlling for turnover intention at Time 1: PE related positively to turnover intention when job control was low. Furthermore, PE at Time 1 was not significantly related and job resources at Tim…
Work characteristics in long-term temporary workers and temporary-to-permanent workers: A prospective study among Finnish health care personnel
2011
In this study, the authors seek to account for possible transitions from temporary to permanent employment in relation to perceived psychosocial work characteristics, i.e. job insecurity, workload, job control and organizational communication. The study compared three groups of Finnish hospital workers utilizing a two-wave design with a two-year time lag: (1) workers who were temporarily employed at Time 1 but permanently employed at Time 2 (temporary-to-permanent workers; n = 25); (2) workers who were temporarily employed at Time 1 and at Time 2 (long-term temporary workers; n = 45); and (3) a reference group of workers who were permanently employed at Time 1 and Time 2 (permanent workers…
Perceived employability: Investigating outcomes among involuntary and voluntary temporary employees compared to permanent employees
2011
PurposeThe purpose of the present study is to examine how perceived employability relates to job exhaustion, psychological symptoms and self‐rated job performance in involuntary and voluntary temporary employees compared to permanent employees.Design/methodology/approachThe study is based on a cross‐sectional design using a sample of university teachers and researchers (n=1,014) from two Finnish universities. Of the sample, 40 percent (n=408) are permanent employees, 49 percent (n=495) involuntary and 11 percent (n=111) voluntary temporary employees. Most respondents (54 percent) have education above a Master's degree, the average age is 43 years, and 58 percent are women.FindingsThe result…
