Early Impulse Control: Treatment of Potential Errors within Pre-Programming and Control

Abstract

Early aiming adjustments following an online perturbation are made possible by impulse control. This process may unfold even earlier when perturbations impose a greater risk of a costly overshoot error. Participants executed upward and downward aims to mediate the cost of potential errors—downward overshoots require more energy to correct against gravity. On 33% of the trials, texture elements on the aiming surface were shifted following onset to appear congruent or incongruent with the aiming direction, and consequently generate a misperception of the limb moving slower or faster, respectively. Thus, the risk of potential errors could be influenced by the online perturbation (e.g., increased perceived likelihood of overshooting following the incongruent background). Findings indicated greater undershooting for down compared to up, which reflects the principle of movement optimisation. There was also more undershooting for an incongruent compared to congruent background, which is consistent with early online adjustments counter-acting the misperceived limb velocity. However, there were no interactions throughout the movement trajectory. We suggest that while the initial pre-programme considers the cost of potential errors (target direction), early impulse control fails to discriminate the likelihood of these errors occurring following an online perturbation (moving background).     

Rethinking relationships in cyberspace

ABSTRACT

The ubiquity of the internet, which has been extensively theorised in the social sciences, provides, for some, a radically new context in which we must rethink both the significance and the performance of being human. For others, the internet is an extension rather than revision of our pre-existing practices, meaning that what it is to be human remains largely unchanged. This is a stimulating and pressing context for theological anthropological reflection: theological doctrines do not specifically address cyberspace, but they suggest idea(l)s of being human that are, on the one hand, enduring and yet can also be read as flexible for different contexts. What, then, are the challenges and promises that digital contexts pose for models of theological anthropology, specifically ones that highlight the significance of human relationships? Do digital contexts overstretch idea(l)s of human nature? On what grounds can we assess and reflect on our conduct in cyberspace?     

线上社交焦虑:社交媒体中的人际负性体验

线上社交焦虑指个体在社交媒体交往情境中感知到的紧张和恐惧等人际负性体验,包含隐私担忧、交往焦虑和负面评价恐惧三个方面。线上社交焦虑可以通过质性分析法、实验诱发法和问卷测量法进行研究。线上社交焦虑既会受到社交媒体自身特点、个体特征因素、网络欺凌和文化因素的影响,还会对个体的心理与行为产生后效。未来研究者需要开发有效的本土化测量工具、探索其形成和作用机制、关注线上社交焦虑悖论以及推动对其干预。     

Development of the Uni Virtual Clinic: an online programme for improving the mental health of university students

ABSTRACT

There is growing recognition of the importance of addressing the mental health needs of young people attending university. Anonymous, scalable, and evidence-based online interventions can help to reduce burden on university services and increase access to care for marginalised or disconnected students. This paper reports the participatory design methods used to develop the Uni Virtual Clinic (UVC), a comprehensive online programme that was designed to prevent and treat mental health problems and related issues in university students. Data evaluating the participatory design process is also presented. The potential for the implementation of the UVC within university-based counselling services is strong, and has potential to reduce the prevalence of mental disorders in a high-risk group of young people.     

Highs and Lows in Motor Control Development

Abstract

Motor control is classically described as relying on two components: anticipatory control (feedforward processing) and online control (feedback processing). Here we aimed to unveil the developmental steps of both feedback and feedforward control in 5–10 years old children, using a simple and ecological task. We manipulated object’s weight in a reach-to-displace paradigm. When the weight was known before lifting it, anticipatory processes were quantifiable during the reaching phase. Conversely, an unknown weight triggered online corrections during the displacing phase. Movement kinematics revealed that children anticipate this objet property as young as 5 y-o. This anticipation becomes adequate around 7 y-o and is paralleled by poor online corrections. This simple yet relevant paradigm should allow quantifying deviations from neurotypical patterns in disorders of motor control.     

Personnel selection in the digital age: a review of validity and applicant reactions,and future research challenges

ABSTRACT

We present a targeted review of recent developments and advances in digital selection procedures (DSPs) with particular attention to advances in internet-based techniques. By reviewing the emergence of DSPs in selection research and practice, we highlight five main categories of methods (online applications, online psychometric testing, digital interviews, gamified assessment and social media). We discuss the evidence base for each of these DSP groups, focusing on construct and criterion validity, and applicant reactions to their use in organizations. Based on the findings of our review, we present a critique of the evidence base for DSPs in industrial, work and organizational psychology and set out an agenda for advancing research. We identify pressing gaps in our understanding of DSPs, and ten key questions to be answered. Given that DSPs are likely to depart further from traditional non-digital selection procedures in the future, a theme in this agenda is the need to establish a distinct and specific literature on DSPs, and to do so at a pace that reflects the speed of the underlying technological advancement. In concluding, we, therefore, issue a call to action for selection researchers in work and organizational psychology to commence a new and rigorous multidisciplinary programme of scientific study of DSPs.     

Selfie posting behaviors are associated with narcissism among men

Although many studies have investigated individual differences in online social networking, few have examined the recent and rapidly popularized social phenomenon of the “selfie” (a selfportrait photograph of oneself). In two studies with a pooled sample of 1296 men and women, we tested the prediction that individuals who score high on four narcissism sub-scales (Self-sufficiency, Vanity, Leadership, and Admiration Demand) will be more likely to post selfies to social media sites than will individuals who exhibit low narcissism. We examined three categories of selfies: own selfies; selfies with a romantic partner; and group selfies, controlling for non-selfie photographs. Women posted more selfies of all types than did men. However, women’s selfie-posting behavior was generally unrelated to their narcissism scores. In contrast, men’s overall narcissism scores positively predicted posting own selfies, selfies with a partner, and group selfies. Moreover, men’s Vanity, Leadership, and Admiration Demand scores each independently predicted the posting of one or more types of selfies. Our findings provide the first evidence that the link between narcissism and selfie-posting behavior is comparatively weak among women than men, and provide novel insight into the social motivations and functions of online social networking.     

Living the eighth day online: liturgies,sacramental life,and building human relationships

ABSTRACT

Online human relationships can exacerbate some of the worst of our tendencies toward each other, including deception, selfishness, apathy and disembodiment, and sexual harassment. Yet Christians can also bring their prayer practices online, as ways of bringing God’s new creation (known in Christian tradition as the Eighth Day) to the forefront. Through examination of three distinctive online prayer practices, combined with discussion of liturgical and sacramental theologies, this article shows that prayer online also holds out possibilities of reconciliation and justice as potential responses to negative human relationship tendencies.     

社交网站中的自我呈现与青少年网络利他行为:网络社交效能和希望的作用

为考察社交网站中的积极自我呈现、真实自我呈现对青少年网络利他行为的影响以及网络社交效能和希望在其中的中介作用，采用社交网站中的积极自我呈现和真实自我呈现问卷、网络利他行为量表、网络社交效能问卷和希望量表对安徽、福建、河南、湖南、山西、天津、云南等省份八所中学的805名初中二年级学生（男生427名，女生378名；被试平均年龄为13.38岁，SD=0.63）进行问卷调查。研究显示：（1）社交网站中的积极自我呈现和真实自我呈现均能正向预测青少年网络利他行为；（2）网络社交效能在积极自我呈现与青少年的网络利他行为之间起中介作用，也在真实自我呈现与青少年的网络利他行为之间起中介作用；（3）希望在真实自我呈现与青少年的网络利他行为之间起中介作用。
