Correspondence analysis, multiple correspondence analysis and their discriminant counterparts (i.e., discriminant simple correspondence analysis and discriminant multiple correspondence analysis) are methods of choice for analyzing multivariate categorical data. In these methods, variables are integrated into optimal components computed as linear c...
In practical visual search fields, observers often encounter errors that result from an unknown number of targets, which may induce reduced accuracy and speed. Our current study addresses the potential enhancement of collaborative search efficiency as a dyad to mitigate such incurred search costs. Utilizing the capacity coefficient, we evaluated se...
Two intriguing papers of the late 1990’s and early 2000s by J. Tanaka and colleagues put forth the hypothesis that a repository of face memories can be viewed as a vector space where points in the space represent faces and each of these is surrounded by an attractor field. This hypothesis broadens the thesis of T. Valentine that face space is const...
This study delves into expressing primary emotions anger, happiness, sadness, and fear through drawings. Moving beyond the well-researched color-emotion link, it explores under-examined aspects like spatial concepts and drawing styles. Employing Python and OpenCV for objective analysis, we make a breakthrough by converting subjective perceptions in...
Associations among cognitive ability, depressive symptoms, and psychological resilience have been found, but the interaction among these variables remains unclear, especially for young adults. The current study aimed to investigate how these variables interact in young adults. A total of 192 participants (97 female) with a mean age of 21.84 years (...
How the brain maintains stability in its internal states is fundamental to understanding human resilience of psychological states against external perturbations. Here, we evaluated the neurocomputational stability of the default mode network (DMN) using indices of its functional transitions based on multi-voxel states and conventional regional mean...
Background
Encountering challenges and stress heightens the vulnerability to mental disorders and diminishes well-being. This study explores the impact of psychological resilience in the context of adverse events, considering age-related variations in its influence on well-being.
Methods
A total of 442 participants (male vs. female =48% vs. 52%) w...
Physical activity has been viewed as a potential non-pharmacological therapeutic strategy to improve the clinical symptoms and neurocognitive deficits in patients with schizophrenia. However, there are various types of physical activities, and different exercise prescriptions might produce inconsistent benefits. Thus, this study aimed to conduct a...
Managing contradictions and building resilience help us overcome life's challenges. Here, we explored the link between attitudes towards contradictions and psychological resilience, examining the role of cortical conflict resolution networks. We enlisted 173 healthy young adults and used questionnaires to evaluate their cognitive thinking styles an...
Prior research has highlighted the potential impact of aerobic exercise on cognitive functioning, particularly in situations demanding heightened cognitive control. However, the mechanism underlying this cognitive enhancement has remained unknown. To address this issue, this study examined the impact of a 4-week aerobic exercise program on cognitiv...
Introduction
Pulse harmonic analysis is a quantitative and objective methodology within traditional Chinese medicine (TCM) used to evaluate pulse characteristics. However, interpreting pulse wave data is challenging due to its inherent complexity. This study aims to provide a comprehensive review and comparison of existing human pulse wave harmonic...
Previous research has presented conflicting evidence regarding whether Chinese characters are processed holistically. In past work, we applied Systems Factorial Technology (SFT) and discovered that native Chinese speakers exhibited limited capacity when processing characters and words. To pinpoint the source of this limitation, our current research...
The Word Superiority Effect (WSE) refers to the phenomenon where a single letter is recognized more accurately when presented within a word, compared to when it is presented alone or in a random string. However, previous research has produced conflicting findings regarding whether this effect also occurs in the processing of Chinese characters. The...
The mental health of adolescent athletes is important for their performance and career growth as they experience both physical and psychological development. Research has shown that stable psychological state helps athletes maintain mental health during stressful situations. The Peace of Mind (PoM) Index is a measure of psychological well-being in...
Previous studies have demonstrated a positive relationship between aerobic fitness and cognitive control, the ability to inhibit distractions (conflict control) or impulsive actions (response inhibition). However, it is unknown whether these sub-processes and their underlying information processing capacity are differentially related to aerobic fit...
Peace of mind (PoM) is an index of mental health in Asian culture and emphasizes low arousal, happiness, harmony, and an internal state of peacefulness. While previous studies have found that mindful self-awareness can contribute to PoM, regular physical activity (PA) is also an important factor contributing to one’s PoM due to its function in prom...
Sport expertise has been shown to modulate the cognitive advantage in open-skill athletes, with evidence for a greater advantage for athletes practicing interceptive sports relative to strategic sports. However, this conclusion is solely based on central tendency measures such as accuracy or mean reaction time (RT), dismissing important information...
We employed the Riemannian Face Manifold (RFM) as an alternative approach to the conventional linear Euclidean space for explaining the atypicality bias in face likeliness judgments. The RFM posits that the mental representation of faces is better captured as a manifold of stable states, accounting for the nonlinearity in the physical properties of...
Psychosocial factors, including life satisfaction, resilience, and social support, have been proposed to influence depressive symptom severity in adults because the age of onset of depressive disorders, i.e. adolescence to early adulthood, is associated with various impairments in psychosocial functioning. In this study, a psychosocial model was co...
Researchers in the field of face perception have long debated the extent to which we process faces holistically (as a whole) versus analytically (focusing on individual features). While some evidence suggests that faces are perceived holistically, research on the neural organization of the visual system and people's subjective experiences indicate...
In high demand contexts, uni- or multi-modal signals are used to convey redundant information and improve performance. This is especially the case with improving the detection of discrete peripheral signals. However, how one processes peripheral signals may change depending on the greater environmental context. The underlying cognitive processing o...
Resilience is a process associated with the ability to recover from stress and adversity. We aimed to explore the resilience-associated DNA methylation signatures and evaluate the abilities of methylation risk scores to discriminate low resilience (LR) individuals. The study recruited 78 young adults and used Connor-Davidson Resilience Scale (CD-RI...
Despite numerous investigations of the prevalence effect on medical image perception, little research has been done to examine the effect of expertise, and its possible interaction with prevalence. In this study, medical practitioners were instructed to detect the presence of hip fracture in 50 X-ray images with either high prevalence ( N signal =...
Associations among cognitive ability, depressive symptoms, and psychological resilience have been found, but the interaction among these variables remains unclear, especially for young adults. The current study aimed to investigate how these variables interact in young adults in Taiwan. A total of 192 participants (97 female) with a mean age of 21....
The use of information technologies for the public interest, such as COVID-19 tracking apps that aim to reduce the spread of COVID-19 during the pandemic, involve a dilemma between public interest benefits and privacy concerns. Critical in resolving this conflict of interest are citizens’ trust in the government and the risks posed by COVID-19. How...
Although aerobic fitness has been thought to protect against the detrimental cognitive effects following exhaustive exercise, available evidence from studies using traditional mean behavioral measures remain somewhat equivocal.
Purpose
This study aimed to reconcile this discrepancy by using a novel theory-driven diagnostic tool, the Systems Factor...
Adaptability is a key competency for career success. Previous studies have demonstrated that proactive personality is identified as a strong predictor of career adaptability. Proactive individuals are more likely to adopt positive coping strategies in the face of external environmental stress, rather than passively being constrained by the environm...

Surgical removal is the treatment of choice for second branchial cleft cysts (SBCCs), which are congenital anomalies. The conventional procedure is performed through a transcervical approach, which would lead to a visible scar in the anterior neck. Conversely, the postauricular approach could keep the scar in the hairline or retroauricular sulcus,...
Background
The Connor–Davidson Resilience Scale (CD-RISC) and the Brief Resilience Scale (BRS) are two scales widely used to measure resilience. Although both scales seek to assess an individual's ability to recover from and adapt to disruptions or stressful events, they can capture different aspects of resilience. While the CD-RISC focuses on reso...
COVID-19 is a thorny challenge of global public health. To curb the rapid spread of the epidemic, the World Health Organization recommends a series of public health measures including “social distance” and “different levels of lockdown”. However, these restrictive measures have completely changed people’s lifestyles. Although these measures are con...

Taiwan has been a world leader in controlling the spread of SARS-CoV-2 during the COVID-19 pandemic. Recently, the Taiwan Government launched its COVID-19 tracing app, ‘Taiwan Social Distancing App’; however, the effectiveness of this tracing app depends on its acceptance and uptake among the general population. We measured the acceptance of three...
Aerobic exercise has been identified as an effective strategy for transiently enhancing inhibitory control, an ability to suppress irrelevant distractors while focusing on relevant information in facilitating the implementation of goal-directed behavior. The purpose of this study was to employ a go/no-go version of the redundant-target task and eve...
Numerals are part of our everyday lives and are regularly viewed in less-than ideal conditions. Mistaking one numeral for another is almost an inevitability, and the cost of these confusions could be insignificant or hugely expensive! Numeral confusions can be explained by distances between our mental representations — how we internally represent t...

Although great progress has been made in our understanding of perceptual-cognitive expertise in team sports, the neurocognitive mechanisms underlying such cognitive advantage in the face of multiple, sometimes conflicting, channels of information are not well understood. Two electroencephalographic indices associated with perceptual decisions, the...
It has widely been accepted that aggregating group-level decisions is superior to individual decisions. As compared to individuals, groups tend to show a decision advantage in their response accuracy. However, there has been a lack of research exploring whether group decisions are more efficient than individual decisions with a faster information-p...
People may differ in their ways of processing tasks or situations, which may be explained by cognitive styles that define individual differences in information processing strategies. The cognitive style ranges between two extremes: analytic and holistic processing style. The concept of cognitive style has been widely investigated in the literature,...
This editorial introduces the special issue dedicated to sampling models.
People express quantities using a remarkably small set of units and digits. Confusing digits could be costly, and not all confusions are the same; confusing a price tag of 2 dollars with 9 dollars is naturally more costly than confusing 2 with 3. Confusion patterns are intimately related to the distances between our mental representations and hypot...
This study aimed to determine whether individual differences in analytic-holistic cognitive style are associated with flanker task performance and, furthermore, to pinpoint at what stage(s) of information processing this association occurs, as indexed by event-related potential (ERP) components. The first experiment demonstrated that age-related di...
Systems factorial technology (SFT; Townsend & Nozawa, 1995) is regarded as a useful tool to diagnose if features (or dimensions) of the investigated stimulus are processed in a parallel or serial fashion. In order to use SFT, one has to assume the speed to process each feature is influenced by that feature only, termed as selective influence (Stern...

Although recent evidence has demonstrated the potent effect of physical exercise to increase the efficacy of cognitive training, the neural mechanisms underlying this causal relationship remain unclear. Here, we used multiscale entropy (MSE) of electroencephalography (EEG)—a measure of brain signal complexity—to address this issue. Young males were...
We examined performance in a cued detection task when a peripheral cue was either 50% or 100% valid, tested in separate experiments. We combined a Posner cueing task with a double factorial manipulation of stimulus salience. Unlike previous investigations in which participants responded to either target, we employed an AND decision task in which a...
Objective:
Extensive evidence has demonstrated the relationship between aerobic fitness and cognitive function in early adulthood. Little is known, however, about whether the cognitive benefits of aerobic fitness are related to the modulation of top-down or bottom-up mechanisms in the control of executive attention. The present study aimed to shed...
The segregated representations pertinent to childhood relational trauma have long been posited as a key pathogenic mechanism for dissociation. Yet, the weak to moderate correlation of child maltreatment with dissociation proneness leads to the question about which factors may moderate the impact of adverse childhood interpersonal experiences and wo...

In this chapter, we explore the foundations of a major analytical foundation of Systems Factorial Technology (SFT) - the Double Factorial Paradigm (DFP). The experimental methodology of the DFP was developed by Townsend and colleagues for the purposes of examining the architecture and efficiency of an information processing system. The experimenter...
Selective attention has a direct influence on perceptual decision making. This chapter reviews how attention biases or facilitates judgments of sensory stimuli by examining decision-theoretic models, such as the signal detection model and sequential sampling models. These models assume that the processing order of multiple signals is invariant to a...
We ask whether auditory and visual signals are processed using a consistent mental architecture across variable experimental designs. It is well-known that in an auditory-visual task requiring divided attention, responses are often faster for redundant audiovisual targets compared to unisensory targets. Importantly, these redundant-target effects c...
