Media multitasking is associated with distractibility and increased prefrontal activity in adolescents and young adults.
2016
The current generation of young people indulges in more media multitasking behavior (e.g., instant messaging while watching videos) in their everyday lives than older generations. Concerns have been raised about how this might affect their attentional functioning, as previous studies have indicated that extensive mediamultitasking in everyday life may be associated with decreased attentional control. In the current study, 149 adolescents and young adults (aged 13-24 years) performed speech-listening and reading tasks that required maintaining attention in the presence of distractor stimuli in the othermodality or dividing attention between two concurrent tasks. Brain activity during task pe…
Gaming is related to enhanced working memory performance and task-related cortical activity
2017
Gaming experience has been suggested to lead to performance enhancements in a wide variety of working memory tasks. Previous studies have, however, mostly focused on adult expert gamers and have not included measurements of both behavioral performance and brain activity. In the current study, 167 adolescents and young adults (aged 13–24 years) with different amounts of gaming experience performed an n-back working memory task with vowels, with the sensory modality of the vowel stream switching between audition and vision at random intervals. We studied the relationship between self-reported daily gaming activity, working memory (n-back) task performance and related brain activity measured u…
Reading skill and neural processing accuracy improvement after a 3-hour intervention in preschoolers with difficulties in reading-related skills
2012
This study aimed at determining whether an intervention game developed for strengthening phonological awareness has a remediating effect on reading skills and central auditory processing in 6-year-old preschool children with difficulties in reading-related skills. After a 3-hour training only, these children made a greater progress in reading-related skills than did their matched controls who did mathematical exercises following comparable training format. Furthermore, the results suggest that this brief intervention might be beneficial in modulating the neural basis of phonetic discrimination as an enhanced speech-elicited mismatch negativity (MMN) was seen in the intervention group, indic…
Children's disclosures of sexual abuse in a population-based sample
2018
Most previous studies on disclosing child sexual abuse (CSA) have either been retrospective or focused on children who already have disclosed. The present study aimed to explore the overall CSA disclosure rate and factors associated with disclosing to adults in a large population-based sample. A representative sample of 11,364 sixth and ninth graders participated in the Finnish Child Victim Survey concerning experiences of violence, including CSA. CSA was defined as having sexual experiences with a person at least five years older at the time of the experience. Within this sample, the CSA prevalence was 2.4%. Children reporting CSA experiences also answered questions regarding disclosure, t…
Memory-Based Mismatch Response to Frequency Changes in Rats
2011
Any occasional changes in the acoustic environment are of potential importance for survival. In humans, the preattentive detection of such changes generates the mismatch negativity (MMN) component of event-related brain potentials. MMN is elicited to rare changes (‘deviants’) in a series of otherwise regularly repeating stimuli (‘standards’). Deviant stimuli are detected on the basis of a neural comparison process between the input from the current stimulus and the sensory memory trace of the standard stimuli. It is, however, unclear to what extent animals show a similar comparison process in response to auditory changes. To resolve this issue, epidural potentials were recorded above the pr…
Group Music Therapy as a Preventive Intervention for Young People at Risk : Cluster-Randomized Trial
2017
Background Music forms an important part of the lives and identities of adolescents and may have positive or negative mental health implications. Music therapy can be effective for mental disorders such as depression, but its preventive potential is unknown. Objective The aim of this study was to examine whether group music therapy (GMT) is an effective intervention for young people who may be at risk of developing mental health problems, as indicated via unhealthy music use. The main question was whether GMT can reduce unhealthy uses of music and increase potentials for healthy uses of music, compared to self-directed music listening (SDML). We were also interested in effects of GMT on dep…
Processing of word stress related acoustic information : A multi-feature MMN study
2016
In the present study, we investigated the processing of word stress related acoustic features in a word context. In a passive oddball multi-feature MMN experiment, we presented a disyllabic pseudo-word with two acoustically similar syllables as standard stimulus, and five contrasting deviants that differed from the standard in that they were either stressed on the first syllable or contained a vowel change. Stress was realized by an increase of f0, intensity, vowel duration or consonant duration. The vowel change was used to investigate if phonemic and prosodic changes elicit different MMN components. As a control condition, we presented non-speech counterparts of the speech stimuli. Result…
Effects of medication, treatment, and behavioral beliefs on intentions to take medication in patients with familial hypercholesterolemia
2018
Although familial hypercholesterolemia (FH) can be effectively managed using cholesterol-lowering medication, patients often fall short of complete treatment adherence. Identifying the psychological factors associated with self-regulation of FH medication is important to inform interventions to maximize adherence. The aim of the present study was to test an integrated psychological model in predicting FH patients' intentions to take medication.FH patients attending clinics in seven countries were invited to participate in a cross-sectional survey study. Consenting patients (N = 551) completed self-report measures of generalized beliefs about medication overuse and harms, beliefs in treatmen…
Emotional labour and work engagement among nurses: examining perceived compassion, leadership and work ethic as stress buffers
2015
Aim The study examined whether three resources, that is, compassion, transformational leadership and work ethic feasibility, buffer against the negative effects of emotional labour on work engagement. Background Emotional labour is a common job stressor among nurses, but little is known about whether certain personal and work resources buffer against it in relation to work engagement. Revealing buffers of emotional labour would help organizations to design tailored interventions. Design Cross-sectional online survey conducted in 2014. Methods Participants were 3466 Finnish nurses. Hypotheses were tested via hierarchical moderated regression analyses. Results Higher emotional labour related …
Semantic anomaly detection in school-aged children during natural sentence reading : A study of fixation-related brain potentials
2018
In this study, we investigated the effects of context-related semantic anomalies on the fixation-related brain potentials of 12–13-year-old Finnish children in grade 6 during sentence reading. The detection of such anomalies is typically reflected in the N400 event-related potential. We also examined whether the representation invoked by the sentence context extends to the orthographic representation level by replacing the final words of the sentence with an anomalous word neighbour of a plausible word. The eye-movement results show that the anomalous word neighbours of plausible words cause similar first-fixation and gaze duration reactions, as do other anomalous words. Similarly, we obser…
