Hydration status in a representative UK sample
No full textIn this cross-sectional survey we aim to collect consumption and hydration measures from a representative UK sample to more closely assess the association between beverage intake and hydration status. In addition, research has identified socioeconomic gradients in beverage consumption patterns and hydration status but, to our knowledge, this association has not yet been explored in a representative UK sample. Therefore, a second aim of this survey will be to assess socioeconomic gradients in beverage consumption
Can neuronal excitation/inhibition predict the effects of HD-tDCS on the executive vigilance decrement?
No full textThis study aims to test whether the aperiodic exponent change (post- minus pre-stimulation EEG measurement) reflects the mechanistic effects of HD-tDCS, and whether the baseline aperiodic exponent can predict HD-tDCS efficacy in mitigating the executive vigilance decrement
Is the mitigation of the executive vigilance decrement by HD-tDCS dependent on cognitive load?
No full textIn the current study, we want to compare the effects of either anodal or sham HD-tDCS over the rPPC, combined with different versions of a vigilance task, manipulating cognitive load. Namely, participants will either perform a single task, measuring executive vigilance, or a dual task, where executive and arousal vigilance are measured. Further comparisons will also be made with data from a triple task (standard ANTI-Vea, of a previously collected sample; Hemmerich et al., in preparation), in line with the approach taken by Luna et al. (2022) in order to accumulate large sample sizes. Given the specificity of HD-tDCS effects and the effect of task load manipulations on EV; we expect to find neuromodulatory effects, specifically in those conditions that have proven to produce a steeper vigilance decrement, namely the single and triple conditions
Examining cross-cultural similarities and differences in people’s attitudes toward political apologies.
No full textAs part of a larger five-year project (1 September 2016 – 1 March 2022), funded by the European Research Council (reference: 682077-APOLOGY), we investigate how political apologies are viewed across cultures.
Past research suggests that people may support their country apologizing for past wrongdoings, when they feel guilt, and possibly, shame, for their country’s actions. Much of this research, however, has been conducted using predominantly Western and student-based samples. As a result, it is unclear how political apologies are perceived and valued across the world, and whether they have a universal potential to redress past wrongdoings.
In this study, we examine how people across the world think about political apologies for past wrongdoings by their country, and how this is related to notions about collective responsibility and reputational concerns, and to feelings of group-based guilt and shame. We are particularly interested in whether or not any variation in this regard can be explained by the cultural context (controlling for potential confounds at the individual and country level)
What do we know about nursing practice in relation to functional ability limitations, frailty and models of care among older people in home- and facility-based care: a scoping review
No full textThis is a registration for a scoping review with the aim to map published literature on how functional ability limitations and frailty among older people (65 and above) in home-and facility-based care (i.e. long-term care) were described by key stakeholders, and to identify models of care (MoCs) targeting these conditions
Tuberculosis in india: a scoping review
No full textTuberculosis is still a leading cause of death in India. This study is aimed at scoping all related dat
Experiment S3
No full textIn this study, we present participants with image sequences depicting either individuals or dyads building block towers. Individual actors build the tower by alternating between using their left and right hands to place blocks atop it. Dyads distribute this task such that they take turns placing blocks on the tower. Occasionally, an alternation violation occurs in which the same hand (individual condition) or the same actor (joint/dyad condition) places two blocks atop the tower in a row. This ends the image sequence.
Upon seeing a block placed on the tower, participants will be asked to make rapid keypress responses to indicate either the colour of the block or the side of the screen from which it came.
We aim to test whether social contexts modulate observers predicted actions by comparing participants' response times and error rates (combined as inverse efficiency scores) across individual and joint image sets
Exploration of Asymmetry between conditions in Stroop Task
No full textThe purpose of this paper is to present a case for creating a Non-Linear Diffusion Model of Conflict Tasks. The paper aims to find a systematic difference between the mean difference in reaction time between incongruent and neutral trials versus congruent and neutral trials. The experiment we are running is a base Stroop Task with a word stimuli block and a shape stimuli block to check for possible asymmetry in reaction time differences between conditions
Examining the Discriminant/Convergent Validity of Personality Dimensions of Interactive Agents
No full textOur research examines social perceptions regarding adaptive and personalized “interactive agent” technologies. We have proposed a personality model containing two primary factors (“friendly” and “reliable”) and seven underlying facets. This research aims to assess the discriminant and convergent validity of the IA Personality scale by examining its relationship with other related existing constructs
