Inattention and Uncertainty in the Predictive Brain
2021
Negative effects of inattention on task performance can be seen in many contexts of society and human behavior, such as traffic, work, and sports. In traffic, inattention is one of the most frequently cited causal factors in accidents. In order to identify inattention and mitigate its negative effects, there is a need for quantifying attentional demands of dynamic tasks, with a credible basis in cognitive modeling and neuroscience. Recent developments in cognitive science have led to theories of cognition suggesting that brains are an advanced prediction engine. The function of this prediction engine is to support perception and action by continuously matching incoming sensory input with to…
Hand‐related action words impair action anticipation in expert table tennis players : Behavioral and neural evidence
2021
Athletes extract kinematic information to anticipate action outcomes. Here, we examined the influence of linguistic information (experiment 1, 2) and its underlying neural correlates (experiment 2) on anticipatory judgment. Table tennis experts and novices remembered a hand- or leg-related verb or a spatial location while predicting the trajectory of a ball in a video occluded at the moment of the serve. Experiment 1 showed that predictions by experts were more accurate than novices, but experts’ accuracy significantly decreased when hand-related words versus spatial locations were memorized. For nonoccluded videos with ball trajectories congruent or incongruent with server actions in exper…
Acute Effects of High-intensity Resistance Exercise on Cognitive Function
2021
The purpose of the present study was to examine the influence of an acute bout of high-intensity resistance exercise on measures of cognitive function. Ten men (Mean ± SD: age = 24.4 ± 3.2 yrs; body mass = 85.7 ± 11.8 kg; height = 1.78 ± 0.08 m; 1 repetition maximum (1RM) = 139.0 ± 24.1 kg) gave informed consent and performed a high-intensity 6 sets of 10 repetitions of barbell back squat exercise at 80% 1RM with 2 minutes rest between sets. The Automated Neuropsychological Assessment Metrics (ANAM) was completed to assess various cognitive domains during the familiarization period, immediately before, and immediately after the high-intensity resistance exercise bout. The repeated measures …
Task-Modulated Corticocortical Synchrony in the Cognitive-Motor Network Supporting Handwriting
2019
Abstract Both motor and cognitive aspects of behavior depend on dynamic, accurately timed neural processes in large-scale brain networks. Here, we studied synchronous interplay between cortical regions during production of cognitive-motor sequences in humans. Specifically, variants of handwriting that differed in motor variability, linguistic content, and memorization of movement cues were contrasted to unveil functional sensitivity of corticocortical connections. Data-driven magnetoencephalography mapping (n = 10) uncovered modulation of mostly left-hemispheric corticocortical interactions, as quantified by relative changes in phase synchronization. At low frequencies (~2–13 Hz), enhanced …
Multitasking in Driving as Optimal Adaptation Under Uncertainty
2021
Objective The objective was to better understand how people adapt multitasking behavior when circumstances in driving change and how safe versus unsafe behaviors emerge. Background Multitasking strategies in driving adapt to changes in the task environment, but the cognitive mechanisms of this adaptation are not well known. Missing is a unifying account to explain the joint contribution of task constraints, goals, cognitive capabilities, and beliefs about the driving environment. Method We model the driver’s decision to deploy visual attention as a stochastic sequential decision-making problem and propose hierarchical reinforcement learning as a computationally tractable solution to it. The…
The Appraisal Theory of Emotion in Human–Computer Interaction
2020
This chapter reviews the appraisal theory of emotion and how it has been employed in human–computer interaction (HCI) research. This theory views emotion as a process that evaluates the subjective significance of an event. We demonstrate the usefulness of the perspective for HCI, as emotion is defined in terms of the events of the task environment and the goals and knowledge of the subject. Importantly, the appraisal theory ties these factors together in a cognitive appraisal process order to explain the variety of subjective emotional experiences. This is important for two reasons. First, a strong theoretical commitment allows researchers and designers to derive testable hypotheses from th…
Falls, Cognitive Function, and Balance Profiles of Singapore Community-Dwelling Elderly Individuals : Key Risk Factors
2017
Objective: This study compared occurrence of falls, cognitive function, and balance profiles across participants in elderly age categories, investigating associations between the 3 aspects in a sample of Singapore’s elderly population. Method: Community-dwelling elderly individuals (N = 385) were randomly recruited and grouped into “young-old (65-74 years),” “medium-old (75-84 years),” and “oldest-old (above 85 years)” groups. The Fallproof Health and Activity questionnaire, adapted Mini-Mental State Examination (MMSE), and Berg Balance Scale (BBS) tests were used to survey information related to falls, cognition, and balance profiles. Results: Findings revealed significant differences in M…
Building Worlds Together with Sound and Music : Imagination as an Active Engagement between Ourselves
2019
By conforming to the enactive approach to human cognition, and by adopting the Tia DeNora’s concept of human–music interaction as an “in-action” perspective, Kai Tuuri and Henna-Riikka Peltola explore socially extended imagining with sounds and music. This is done through a question of how “shared places” of imagining with sound are established and maintained. Defining the activity of imagining as an essentially dynamic and generative process that takes place in a social reality, the authors propose that the processes of imagining are not only individual but also become exhibited and jointly engaged in social dialogues as well. By first discussing the theoretical foundations of this shared …
Interactionist Approach to Visual Aesthetics in HCI
2021
Visual Aesthetics has gathered interest among scholars in HCI research. The growing interest stems from examinations of the aesthetic-usability effect (“what is beautiful is usable”), and possibly vice versa. Thus, numerous studies focus on understanding how we make sense and experience visual entities in interacting with technology. However, theoretical, and methodological stances vary, which impact conclusions of the studies conducted, and thus, affect design implications. Visual experience research in HCI lacks detailed conceptualizations of the constituents of visual experience and understanding of how these conceptualizations affect the overall research results through implicit methodo…
Neural correlates of morphological processing and its development from pre-school to the first grade in children with and without familial risk for d…
2022
Previous studies have shown that the development of morphological awareness and reading skills are interlinked. However, most have focused on phonological awareness as a risk factor for dyslexia, although there is considerable diversity in the underlying causes of this reading difficulty. Specifically, the relationship between phonology, derivational morphology, and dyslexia in the Finnish language remains unclear. In the present study, we used magnetoencephalography (MEG) to measure the brain responses to correctly and incorrectly derived Finnish nouns in 34 first grade Finnish children (21 typically developing and 13 with familial risk for dyslexia). In addition, we compared longitudinall…
