Computers,information and ethics: A review of issues and literature

Editorial note:The following bibliographic survey of computer ethics is intended as a general introduction useful to guide both preliminary research and course development. It is the first of a series that Carl Mitcham will be doing on a number of specific discussions of ethics in science and technology. Future installments are projected on nuclear ethics, engineering ethics, ethics in scientific research, and biomedical ethics. With this [book] I issue “a call to arms.” The world needs much more discussion and writing on the social and ethical issues surrounding computing. I hope readers .... will take up the challenge.     

NONCONTINGENT PRESENTATION OF ATTENTION AND ALTERNATIVE STIMULI IN THE TREATMENT OF ATTENTION-MAINTAINED DESTRUCTIVE BEHAVIOR

Previous research has demonstrated that destructive behavior may be reduced through noncontingent presentation of attention when attention is identified as the stimulus responsible for behavioral maintenance. Because it may not always be possible to deliver attention in all situations, we examined the extent to which alternative stimuli that have been identified through a choice assessment would substitute for attention (the functional analysis—based reinforcer) in a noncontingent reinforcement procedure. Prior to treatment, functional analyses demonstrated that the destructive behavior of 2 clients with mental retardation was maintained by adult attention. Next, a stimulus choice assessment identified highly preferred tangible items for the 2 clients. Finally, we compared the effectiveness of two noncontingent reinforcement procedures: continuous noncontingent access to attention and continuous noncontingent access to the tangible item identified in the choice assessment. For both clients, these noncontingent reinforcement procedures reduced destructive behavior. The results are discussed in terms of the clinical implications for the treatment of destructive behavior using functional and alternative stimuli.     

Effect of conducting behavioral observations and ratings on staff implementation of a paired-stimulus preference assessment

We assessed the effects of trainees observing and rating the accuracy of others implementing a paired-stimulus preference assessment from video on the trainees' subsequent implementation accuracy. These observational experiences increased implementation accuracy with both a confederate and an actual consumer. These results suggest conducting observations and accuracy ratings may prepare staff to implement behavioral procedures without need of a dedicated trainer.     

Immersion and the illusion of presence in virtual reality

This commentary briefly reviews the history of virtual reality and its use for psychology research, and clarifies the concepts of immersion and the illusion of presence.     

Computerized cognitive training during physical inactivity improves executive functioning in older adults

The hippocampus is closely tied to spatial navigation, a central component in cognitive functioning, and critically involved in age-associated cognitive decline and dementia. This study evaluated a novel, cognitive computerized spatial navigation training (CSNT) program targeting the hippocampus, with expectation of mitigating possible cognitive decline with bed rest (BR). During a 14-day BR study with 16 healthy, older men (mean age = 60 ± 3, range = 55–65 years), half received CSNT for 12 days in 50-min sessions and half were controls (watching documentaries). This design uniquely controlled diet, sleep, and other personal and environmental activities. Although there were no cognitive declines in controls post-BR, CSNT participants demonstrated significant increases in executive/attention ability and processing speed, and continued spatial navigation testing showed improvement to 400 days post-BR. This intervention may prove useful to mitigate cognitive declines known to occur in long periods of immobilization and could have broader implications in protecting against age-related cognitive decline.     

Spirit and truth: Reckoning with the crises of Covid-19 for the Church

The Covid-19 pandemic forces North American churches to reckon with long-standing crises and questions surrounding online community, access to worship, decline in membership, the struggle of small congregations, and the reality of our global communion. This article describes a response grounded in faith defined as confidence in our liberation from pride and despair through Jesus Christ. There is need for clarity of doctrine and spiritual courage to fulfill the church's twofold mission to sustain and grow the body of Christ; both these tasks require courage to approach and speak from the Gospel in ever-new contexts and ages.     

虚拟现实技术在心理学领域的应用与展望

虚拟现实(VR)技术因其能够提高实验研究的生态效度、条件控制水平、可重复性以及避免实地操作带来的危险,被众多研究者引入心理学领域。VR技术除了被用于改良实验程序外,也广泛应用于注意、记忆和执行能力等神经心理测验评估,在恐惧症、焦虑症、创伤后应激障碍和精神分裂症等精神障碍的临床治疗中亦取得丰硕成果。未来研究可致力于改进VR技术本身存在的问题、扩大样本量并扩展研究方法和范围,为VR应用提供更可靠的信效度证据。     

视频游戏虚拟化身对自我概念的影响

虚拟化身(virtual avatar)是玩家在视频游戏中的虚拟自我呈现方式, 通过操控虚拟化身, 玩家可扮演不同的角色, 并拥有新的身份。作为现实自我的投射和展示, 虚拟化身会影响个体的自我认同, 并带来自我的变化。近年来, 越来越多的研究开始关注虚拟化身对个体自我的影响。大量研究表明, 在视频游戏中操纵虚拟化身进行行为和身份模拟会影响个体的自我概念。相关理论从不同视角解释了虚拟化身影响自我概念的原因。另外, 已有研究表明虚拟化身与自我概念的关系受到化身线索、视频游戏特征及个体因素的影响; 自我临场感和化身认同是虚拟化身影响自我概念的内在心理机制。未来研究应关注虚拟化身对自我概念的深层次影响和长期影响, 化身形象和行为两种线索的交互影响, 以及虚拟化身带来的自我概念改变对现实行为的影响, 并加强该领域的应用研究。     

The accuracy of lay integrity assessments in simulated employment interviews

Two studies were conducted to determine if lay judges could accurately assess another individual’s integrity level when using overt and covert integrity inventories. In Study 1, participants took part in simulated employment interviews and then both the participants and lay interviewers completed an overt integrity test comparable to the Reid Report integrity survey [Reid London House. (2004). Abbreviated Reid Report. Minneapolis, MN: NCS Pearson]. Self-lay judge agreement and peer-lay judge agreement were used as the criteria for accuracy. In Study 2, participants took part in either a simulated structured, unstructured or informal employment interview format and completed both overt and covert integrity inventories. The results suggest that lay judges (as well as acquaintances) are fairly accurate in assessing others’ integrity levels based upon a very brief 10-min interaction with an individual, when using either an overt or covert integrity inventory. The findings also suggest that the informal interview format can significantly enhance the accuracy of a lay-judge’s assessment of the participant’s integrity level when a covert measure of integrity is used.
