Effects of verbal tasks with varying difficulty on real-time respiratory airflow during speech generation in healthy young adults
Gullsvåg, Malin; Rodríguez-Aranda, Claudia (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-06-15)Objective: Respiratory function is linked to sensory, affective, and cognitive processes and it is affected by environmental constraints such as cognitive demands. It is suggested that specific cognitive processes, such as working memory or executive functioning, may impact breathing. In turn, various lines of research have suggested a link between peak expiratory airflow (PEF) and cognitive function. ... -
Evaluation of error production in animal fluency and its relationship to frontal tracts in normal aging and mild Alzheimer's disease: A combined LDA and time-course analysis investigation
Itaguchi, Yoshihiro; Castro Chavira, Susana Angelica; Waterloo, Knut; Johnsen, Stein Harald; Rodríguez-Aranda, Claudia (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-01-12)Semantic verbal fluency (VF), assessed by animal category, is a task widely used for early detection of dementia. A feature not regularly assessed is the occurrence of errors such as perseverations and intrusions. So far, no investigation has analyzed the how and when of error occurrence during semantic VF in aging populations, together with their possible neural correlates. The present study aims ... -
Reduction in manual asymmetry and decline in fine manual dexterity in right-handed older adults with mild cognitive impairment
Vasylenko, Olena; Gorecka, Marta Maria; Waterloo, Knut; Rodríguez-Aranda, Claudia (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-08-16)Research in Parkinson’s or Alzheimer’s disease suggests that hand function is affected by neurodegenerative diseases. However, little is known about the relationship between hand function and mild cognitive impairment (MCI). Therefore, we conducted a kinematic analysis of unimanual hand movements in MCI patients to answer whether manual asymmetries and manual dexterity are affected or preserved ...
