Abstract:

Three experiments compared forgetting of the duration of a bar-like visual stimulus with forgetting of its length. The main aim of the experiments was to investigate whether subjective shortening (a decrease in the subjective magnitude of a stimulus as its retention interval increased) was observable in length judgements as well as in time judgements, where subjective shortening has been often observed previously. On all trials of the three experiments, humans received two briefly presented coloured bars, separated by adelay ranging from 1 to 10 s, and the bars could differ in length, duration

Abstract:

Due to the pandemic situation, it become complex to conduct subjective experiments in the anechoic chamber as a result of the lockdown. For this situation the procedure for the subjective experiments without accessing to the anechoic chamber needs to be considered for an alternative approach. The previous study has shown that there are good correlation between the laboratory and online listening test on impact sounds in residential buildings using ambisonic microphone recording with headphone. Hence, further subjective experiments were carried out with monaural and binaural microphone recordin

FOUR EXPERIMENTS INVESTIGATED whether metrical subdivision affects perceived beat tempo. In Experiment 1, musically trained participants tapped in synchrony with the beat of an isochronous pacing sequence and continued tapping the beat after the sequence stopped. Continuation tapping was slower when the pacing beat was subdivided than when it was not. Experiment 2 found the same effect when the subdivisions during synchronization were self-generated. The effect was neutralized, however, when subdivisions were tapped during continuation. In Experiment 3, an effect of subdivision was found in a

The authors report three email surveys that asked authors of articles published in leading journals in psychology, medicine, or statistics to estimate such intervals. Overall response rate (7%) was low, but responses from 360 researchers gave intervals with an average 40% to 50% chance of including replication p, rather than

Abstract:

Background: Recently there has been interest in using subjective ratings as a measure of perceived effort during speech recognition in noise. Perceived effort may be an indicator of cognitive load. Thus, subjective effort ratings during speech recognition in noise may covary both with signal-to-noise ratio (SNR) and individual cognitive capacity. Purpose: The present study investigated the relation between subjective ratings of the effort involved in listening to speech in noise, speech recognition performance, and individual working memory (WM) capacity in hearing impaired hearing aid users.

The authors show that participants' subjective perceptions of prospective duration are not sufficiently sensitive to changes in objective duration and are nonlinear and concave in objective time, consistent with psychophysical principles.

Abstract:

The media quality assessment research community has traditionally been focusing on developing objective algorithms to predict the result of a typical subjective experiment in terms of Mean Opinion Score (MOS) value. However, the MOS, being a single value, is insufficient to model the complexity and diversity of human opinions encountered in an actual subjective experiment. In this work we propose a complementary approach for objective media quality assessment that attempts to more closely model what happens in a subjective experiment in terms of single observers and, at the same time, we perfo

In the current study, we aimed to better understand how people come to make such judgments by introducing a novel distinction between explicit memories of off task thought and subjective feelings of inattention.

In this article, we present new empirical data to assess the status of this pair of connectives. In Experiment 1, we test French-speakers’ intuitions about ‘car’ and ‘parce que’ in a completion task, and compare these results with those of a similar experiment in Dutch. In Experi

Abstract:

Sound is an important, but often neglected, component for creating a self-motion illusion (vection) in Virtual Reality applications, for example, motion simulators. Apart from auditory motion cues, sound can provide contextual information representing self-motion in a virtual environment. In two experiments we investigated the benefits of hearing an engine sound when presenting auditory (Experiment 1) or auditory-vibrotactile (Experiment 2) virtual environments inducing linear vection. The addition of the engine sound to the auditory scene significantly enhanced subjective ratings of vection i

Abstract:

The impact of performance context on subjective mental workload ratings was assessed with the Subjective Workload Assessment Technique (SWAT) and the NASA Task Load Index (TLX). In Experiment 1, a strong context effect was demonstrated. A low range of task difficulty produced considerably higher ratings on a common set of difficulty levels than did a high range of task difficulty. In Experiment 2, increasing the participants′ range of experiences during practice eliminated the context effect. We recommend that methods for standardizing context, such as providing experience with the complete di

Abstract:

We present a haptic feedback technique that combines feedback from a portable force-feedback glove with feedback from direct contact with rigid passive objects. This approach is a haptic analogue of visual mixed reality, since it can be used to haptically combine real and virtual elements in a single display. We discuss device limitations that motivated this combined approach and summarize technological challenges encountered. We present three experiments to evaluate the approach for interactions with buttons and sliders on a virtual control panel. In our first experiment, this approach result

Abstract:

We need data sets of images and subjective scores to develop robust no reference (or blind) visual quality metrics for consumer applications. These applications have many uncontrolled variables because the camera creates the original media and the impairment simultaneously. We do not fully understand how this impacts the integrity of our subjective data. We put forward two new data sets of images from consumer cameras. The first data set, CCRIQ2, uses a strict experiment design, more suitable for camera performance evaluation. The second data set, VIME1, uses a loose experiment design that res

Abstract:

Two experiments were performed to test the effects of varying computer graphics realism cues (wireframe vs. solid figures, flat vs. smooth shading for solid figures, and one or two light sources for solid figures) on the performance of a standard cognitive task (mental rotation) and on the subjective perceived realism of the computer-generated images. In the mental rotation experiment, mean reaction times were slower for wireframe than for smooth and flat shaded images and significant effects for figure complexity and angle of rotation were shown. In the second experiment, subjective ratings o

Abstract:

Previous research showed that fearful faces produce longer temporal estimates than neutral faces. This study probed whether fearful mood enhances this effect. In two experiments, participants viewed neutral and threatening film excerpts and subsequently evaluated the duration of neutral and fearful faces in a bisection task. In Experiment 1, where neutral mood was induced before fearful mood, skin conductance levels (SCLs) and subjective emotion ratings indicated successful mood induction. Compared to neutral mood, fearful mood lengthened subjective duration estimates irrespective of stimulus

Abstract:

Multisensory stimulation is associated with behavioural benefits, including faster processing speed, higher detection accuracy, and increased subjective awareness. These effects are most likely explained by multisensory integration, alertness, or a combination of the two. To examine changes in subjective awareness under multisensory stimulation, we conducted three experiments in which we used Continuous Flash Suppression to mask subthreshold visual targets for healthy observers. Using the Perceptual Awareness Scale, participants reported their level of awareness of the visual target on a trial

Individuals throughout the world are being recruited into studies to examine the social impacts of coronavirus disease 2019 (COVID-19). While previous literature has illustrated how research participation can impact distress and wellbeing, to the authors’ best knowledge no study has examined this in the COVID-19 context. Using an innovative approach, this study analyses the impacts of participation in a COVID-19 survey in Australia on subjective wellbeing through a survey experiment. At a population level, we find no evidence that participation impacts subjective wellbeing. However, this may n

Abstract:

We test the empirical content of the assumption of preference dependent beliefs using a behavioral model of strategic decision making in which the rankings of individuals over final outcomes in simple games influence their beliefs over the opponent’s behavior. This approach— by analogy with Psychological Game Theory—allows for interdependence between preferences and beliefs but reverses the order of causality. We use existing evidence from a multi-stage experiment in which we first elicit distributional preferences in a Random Dictator Game, then estimate beliefs in a related 2×2 effort game c

Abstract Spaciousness is an important psychophysical value of space which has impacts on building occupants’ satisfaction and wellness. Previous research revealed through subjective experiments in spaces without windows that spaciousness is affected not only by the physical volume of space but also by lighting environment, and the effect can be estimated with a calculation model with average luminance and “dark-part-reduced visible volume”. The purpose of this study is to expand the scope of the calculation model to spaces with windows through subjective experiment, and for that, to improve th

The aim of the research was to analyse the process of evacuation from the point of view of the individual’s perception, behaviour and decision making. The study used a survey method that was conducted during two real-scale evacuation experiments in real road tunnels under smoky conditions. All experiments, with fire scenarios and procedures were very similar to real accident. Respondents’ observations and important aspects affecting the evacuation process were verified, including decision-making during evacuation, loss of bearing in smoky conditions and group evacuation.
