Non-game like training benefits spoken foreign-language processing in children with dyslexia

Publisher Copyright: Copyright © 2023 Junttila, Smolander, Karhila, Kurimo and Ylinen.Children with dyslexia often face difficulties in learning foreign languages, which is reflected as weaker neural activation. However, digital language-learning applications could support learning-induced plastic changes in the brain. Here we aimed to investigate whether plastic changes occur in children with dyslexia more readily after targeted training with a digital language-learning game or similar training without game-like elements. We used auditory event-related potentials (ERPs), specifically, the mismatch negativity (MMN), to study learning-induced changes in the brain responses. Participants were 24 school-aged Finnish-speaking children with dyslexia and 24 age-matched typically reading control children. They trained English speech sounds and words with “Say it again, kid!” (SIAK) language-learning game for 5 weeks between ERP measurements. During the game, the players explored game boards and produced English words aloud to score stars as feedback from an automatic speech recognizer. To compare the effectiveness of the training type (game vs. non-game), we embedded in the game some non-game levels stripped of all game-like elements. In the dyslexia group, the non-game training increased the MMN amplitude more than the game training, whereas in the control group the game training increased the MMN response more than the non-game training. In the dyslexia group, the MMN increase with the non-game training correlated with phonological awareness: the children with poorer phonological awareness showed a larger increase in the MMN response. Improved neural processing of foreign speech sounds as indicated by the MMN increase suggests that targeted training with a simple application could alleviate some spoken foreign-language learning difficulties that are related to phonological processing in children with dyslexia.Peer reviewe

Breed differences in social cognition, inhibitory control, and spatial problem-solving ability in the domestic dog (Canis familiaris)

Publisher Copyright: © 2022, The Author(s).The extraordinary genetic and behavioural diversity of dog breeds provides a unique opportunity for investigating the heritability of cognitive traits, such as problem-solving ability, social cognition, inhibitory control, and memory. Previous studies have mainly investigated cognitive differences between breed groups, and information on individual dog breeds is scarce. As a result, findings are often contradictory and inconsistent. The aim of this study was to provide more clarity on between-breed differences of cognitive traits in dogs. We examined the performance of 13 dog breeds (N = 1002 dogs) in a standardized test battery. Significant breed differences were found for understanding of human communicative gestures, following a human’s misleading gesture, spatial problem-solving ability in a V-detour task, inhibitory control in a cylinder test, and persistence and human-directed behaviour during an unsolvable task. Breeds also differed significantly in their behaviour towards an unfamiliar person, activity level, and exploration of a novel environment. No significant differences were identified in tasks measuring memory or logical reasoning. Breed differences thus emerged mainly in tasks measuring social cognition, problem-solving, and inhibitory control. Our results suggest that these traits may have come under diversifying artificial selection in different breeds. These results provide a deeper understanding on breed-specific traits in dogs.Peer reviewe

User Experiences from L2 Children Using a Speech Learning Application : Implications for Developing Speech Training Applications for Children

We investigated user experiences from 117 Finnish children aged between 8 and 12 years in a trial of an English language learning programme that used automatic speech recognition (ASR). We used measures that encompassed both affective reactions and questions tapping into the children' sense of pedagogical utility. We also tested their perception of sound quality and compared reactions of game and nongame-based versions of the application. Results showed that children expressed higher affective ratings for the game compared to nongame version of the application. Children also expressed a preference to play with a friend compared to playing alone or playing within a group. They found that assessment of their speech is useful although they did not necessarily enjoy hearing their own voices. The results are discussed in terms of the implications for user interface (UI) design in speech learning applications for children.Peer reviewe

Implementation of Multimodality Therapy and Minimally Invasive Surgery: Short- and Long-term Outcomes of Gastric Cancer Surgery in Medium-Volume Center

Background Multimodal treatment of gastric cancer includes careful preoperative staging, perioperative oncological treatment, and selective minimally invasive approach. The aim was to evaluate whether this approach improves short- and long-term outcomes in operable gastric cancer. Methods This study included 181 gastric cancer patients who underwent curative intent surgery in Central Finland Central Hospital between years 2005 and 2021 for gastric or esophagogastric junction adenocarcinoma. Those 65 patients in group 1 operated between years 2005-2010 had open surgery with possible adjuvant therapy. During the second period including 58 patients (2011-2015), perioperative chemotherapy and minimally invasive surgery were implemented. The period, when these treatments were standard practise, was years 2016-2021 including 58 patients (group 3). Outcomes were lymph node yield, major complications and 1- and 3-year survival rates. Results Median lymph node yield increased from 17 in group 1 and 20 in group 2 to 23 in group 3 (p p = 0.007; group 2 vs. group 3, p = 0.018), respectively. Overall 1-year survival rates between study groups 1-3 were 78.5% vs. 69.0% vs. 90.2% (p = 0.018) and 3-year rates 44.6% vs. 44.8% vs. 68.1% (p = 0.016), respectively. For overall 3-year mortality, adjusted hazard ratio (HR) was 1.02 (95%CI 0.63-1.66) in group 2 and HR 0.37 (95%CI 0.20-0.68) in group 3 compared to group 1. Conclusions In medium-volume center, modern multimodal therapy in operable gastric cancer combined with minimally invasive surgery increased lymph node yield and improved long-term survival without increasing postoperative morbidity.</p

Social functioning questionnaires of adolescents born preterm show average profiles and attenuated sex differences

Aim Prematurity has been shown to affect social competence in children and adults. Our aim was to evaluate profiles of self-reported social behaviours and loneliness in preterm- and term-born adolescents. Methods Preterm ( Results A total of 172 preterm-born and 134 term-born adolescents returned the questionnaires. Most frequently, preterm adolescents reported a profile of average social competence and average levels of loneliness. Preterm-born boys reported a profile of low social functioning less often (preterm-born 36% vs. term-born 54%), and preterm-born girls reported a profile of high social functioning less frequently (preterm-born 26% vs. term-born 37%) than same-sex controls. Sex differences in social functioning profiles were smaller in preterm than term-born adolescents. Conclusion The majority of young adolescents born preterm reported a high or average social functioning profile irrespective of sex. Prematurity seems to level out differences between the sexes.Peer reviewe
