An experimental study of the feasibility of phase‐based video magnification for damage detection and localisation in operational deflection shapes

M. Civera, L. Zanotti Fragonara, C. Surace

Strain > 56 > 1 > n/a - n/a

Optical measurements from high‐speed, high‐definition video recordings can be used to define the full‐field dynamics of a structure. By comparing the dynamic responses resulting from both damaged and undamaged elements, structural health monitoring can be carried out, similarly as with mounted transducers. Unlike the physical sensors, which provide point‐wise measurements and a limited number of output...

Analysis of the accuracy on computing nominal stress in a biaxial test for arteries

M. Cilla, A. V. Corral, J. A. Peña, E. Peña

Strain > 56 > 1 > n/a - n/a

Biaxial tests are commonly used to investigate the mechanical behaviour of anisotropic soft biological tissues such as cardiovascular tissues. However, there is still no clear understanding of the influence that the biaxial test set‐up conditions may have on the computing material stress of the experimental results. The aim of the present study is to further investigate the accuracy of calculated...

Cognitive resources are distributed among the entire auditory landscape in auditory scene analysis

Renee M. Symonds, Juin W. Zhou, Sally L. Cole, Kelin M. Brace, more

Psychophysiology > 57 > 2 > n/a - n/a

Although attention has been shown to enhance neural representations of selected inputs, the fate of unselected background sounds is still debated. The goal of the current study was to understand how processing resources are distributed among attended and unattended sounds during auditory scene analysis. We used a three‐stream paradigm with four acoustic features uniquely defining each sound stream...

N400/frontal negativity reveals the controlled processes of taxonomic and thematic relationships in semantic priming for artifacts

Xiuling Liang, Feng Xiao, Yi Lei, Hong Li, more

Psychophysiology > 57 > 2 > n/a - n/a

Recent studies show that taxonomic and thematic relationships are functionally and neurologically dissociated; however, there remain some discrepancies due to inconsistencies in definitions, task properties, and concept domains. This issue was further explored via the semantic priming paradigm with a long SOA of 600 ms while controlling for perceptual or functional features of artifacts involved across...

article

Emotional and feature‐based modulation of the early posterior negativity

Andrew H. Farkas, Katelyn I. Oliver, Dean Sabatinelli

Psychophysiology > 57 > 2 > n/a - n/a

The early posterior negativity (EPN) has been shown to be enhanced by emotional relative to neutral scene perception. A subset of studies has also reported a bias in the EPN toward pleasant relative to unpleasant scenes. Functional MRI research has also identified a region in lateral occipital cortex that shows a sensitivity to the visual perception of body parts, which may contribute to the EPN....

Circadian misalignment impairs ability to suppress visual distractions

Andrea N. Smit, Mateusz Michalik, Ashley C. Livingstone, Ralph E. Mistlberger, more

Psychophysiology > 57 > 2 > n/a - n/a

Evening‐type individuals often perform poorly in the morning because of a mismatch between internal circadian time and external social time, a condition recognized as social jet lag. Performance impairments near the morning circadian (~24 hr) trough have been attributed to deficits in attention, but the nature of the impairment is unknown. Using electrophysiological indices of attentional selection...

Frontal theta and posterior alpha in resting EEG: A critical examination of convergent and discriminant validity

Ezra E. Smith, Craig E. Tenke, Patricia J. Deldin, Madhukar H. Trivedi, more

Psychophysiology > 57 > 2 > n/a - n/a

Prior research has identified two resting EEG biomarkers with potential for predicting functional outcomes in depression: theta current density in frontal brain regions (especially rostral anterior cingulate cortex) and alpha power over posterior scalp regions. As little is known about the discriminant and convergent validity of these putative biomarkers, a thorough evaluation of these psychometric...

Influence of cognitive‐motor expertise on brain dynamics of anticipatory‐based outcome processing

Yingzhi Lu, Tiantian Yang, Bradley D. Hatfield, Fengyu Cong, more

Psychophysiology > 57 > 2 > n/a - n/a

Motor experience plays an important role in the ability to anticipate action outcomes, but little is known about the brain processes through which it modulates the preparation for unexpected events. To address this issue, EEG was employed while table tennis players and novices observed videos of serves in order to predict the expected ball direction based on the kinematics of a model’s movement. Furthermore,...

Individual alpha frequency increases during a task but is unchanged by alpha‐band flicker

Michael J. Gray, Tatiana A. Emmanouil

Psychophysiology > 57 > 2 > n/a - n/a

Visual perception fluctuates in sync with ongoing neural oscillations in the delta, theta, and alpha frequency bands of the human EEG. Supporting the relationship between alpha and perceptual sampling, recent work has demonstrated that variations in individual alpha frequency (IAF) correlate with the ability to discriminate one from two stimuli presented briefly in the same location. Other studies...

Stress effects on learning and feedback‐related neural activity depend on feedback delay

Marcus Paul, Christian Bellebaum, Marta Ghio, Boris Suchan, more

Psychophysiology > 57 > 2 > n/a - n/a

Depending on feedback timing, the neural structures involved in learning differ, with the dopamine system including the dorsal striatum and anterior cingulate cortex (ACC) being more important for learning from immediate than delayed feedback. As stress has been shown to promote striatum‐dependent learning, the current study aimed to explore if stress differentially affects learning from and processing...

Dissociable effects of reward magnitude on fronto‐medial theta and FRN during performance monitoring

Katharina Paul, Eliana Vassena, Mario Carlo Severo, Gilles Pourtois

Psychophysiology > 57 > 2 > n/a - n/a

Reward processing is influenced by reward magnitude, as previous EEG studies showed changes in amplitude of the feedback‐related negativity (FRN) and reward positivity (RewP), or power of fronto‐medial theta (FMθ). However, it remains unclear whether these changes are driven by increased reward sensitivity, altered reward predictions, enhanced cognitive control, or a combination of these effects....

Estimating statistical power for event‐related potential studies using the late positive potential

Kyla D. Gibney, George Kypriotakis, Paul M. Cinciripini, Jason D. Robinson, more

Psychophysiology > 57 > 2 > n/a - n/a

The late positive potential (LPP) is a common measurement used to study emotional processes of subjects in ERP paradigms. Despite its extensive use in affective neuroscience, there is presently no gold standard for how to appropriately power ERP studies using the LPP. The present study investigates how the number of trials, number of subjects, and magnitude of the effect size affect statistical power...

The practice of meditation is not associated with improved interoceptive awareness of the heartbeat

Sahib S. Khalsa, David Rudrauf, Mahlega S. Hassanpour, Richard J. Davidson, more

Psychophysiology > 57 > 2 > n/a - n/a

Meditation is commonly assumed to be associated with enhanced interoceptive accuracy. We previously found that experienced meditators did not exhibit a greater ability than nonmeditators to detect heartbeat sensations at rest, despite the meditators' reported subjective ratings of higher accuracy and lower difficulty. Here, attempting to overcome previous methodological limitations, we assessed interoceptive...

Dissonant endings of chord progressions elicit a larger ERAN than ambiguous endings in musicians

Carlota Pagès‐Portabella, Juan M. Toro

Psychophysiology > 57 > 2 > n/a - n/a

In major‐minor tonal music, the hierarchical relationships and patterns of tension/release are essential for its composition and experience. For most listeners, tension leads to an expectation of resolution. Thus, when musical expectations are broken, they are usually perceived as erroneous and elicit specific neural responses such as the early right anterior negativity (ERAN). In the present study,...

Developmental trajectory of the late positive potential: Using temporal‐spatial PCA to characterize within‐subject developmental changes in emotional processing

Elizabeth M. Mulligan, Zachary P. Infantolino, Daniel N. Klein, Greg Hajcak

Psychophysiology > 57 > 2 > n/a - n/a

The late positive potential (LPP) is characterized by temporal and spatial changes across development—though existing work has primarily relied on visual or statistical comparisons of relatively few electrodes and averaged activity over time. The current study used an empirically based approach to characterize temporal and spatial changes in ERPs over time. Data were utilized from a large longitudinal...

Optimizing assessments of post‐error slowing: A neurobehavioral investigation of a flanker task

Hans S. Schroder, Stefanie Nickels, Emilia Cardenas, Micah Breiger, more

Psychophysiology > 57 > 2 > n/a - n/a

Appropriately adjusting to errors is essential for adaptive behavior. Post‐error slowing (PES) refers to the increased reaction times on trials following incorrect relative to correct responses. PES has been used as a metric of cognitive control in basic cognitive neuroscience research as well as clinical contexts. However, calculation of PES varies widely among studies and has not yet been standardized,...

Experimental comparison of energy landscape features of ubiquitin family proteins

Tathagata Nandi, Anju Yadav, Sri Rama Koti Ainavarapu

Proteins: Structure, Function, and Bioinformatics > 88 > 3 > 449 - 461

Small ubiquitin‐related modifiers (SUMO1 and SUMO2) are ubiquitin family proteins, structurally similar to ubiquitin, differing in terms of their amino acid sequence and functions. Therefore, they provide a great platform for investigating sequence‐structure‐stability‐function relationship. Here, we used chemical denaturation in comparing the folding‐unfolding pathways of the SUMO proteins with their...

Geometrical characterization of T cell receptor binding modes reveals class‐specific binding to maximize access to antigen

Nishant K. Singh, Esam T. Abualrous, Cory M. Ayres, Frank Noé, more

Proteins: Structure, Function, and Bioinformatics > 88 > 3 > 503 - 513

Recognition of antigenic peptides bound to major histocompatibility complex (MHC) proteins by αβ T cell receptors (TCRs) is a hallmark of T cell mediated immunity. Recent data suggest that variations in TCR binding geometry may influence T cell signaling, which could help explain outliers in relationships between physical parameters such as TCR‐pMHC binding affinity and T cell function. Traditionally,...
