This study investigated the development of prospective memory using tasks based on the prefrontal-lobe model. Three groups each of 30 children, adolescents, and young adults were compared on prospective-memory performance using ongoing tasks with two levels of cognitive demand (low and high), and two levels of importance (unstressed and stressed) of remembering prospective cues. The Self-Ordered Pointing Task (SOPT), Stroop Color Word Interference Test, and Tower of London were also used to assess relationships between prospective memory and prefrontal-lobe functions. The children remembered fewer prospective cues than either the adolescents or adults, but the adolescents and adults remembered equally well. This trend increased significantly as the cognitive demand of the ongoing tasks increased. However, stressing or not stressing the importance of remembering made no difference to prospective-memory performance. Performance on the SOPT and Stroop Colour Word Interference predicted performance on the high- but not on the low-demand condition. These findings implicate the maturation of the brain's prefrontal region in the development of prospective memory. 相似文献

In human‐computer interaction people often interpret the interaction with the computer as interactions with humans. The social agency theory suggests that social cues like the face and voice of the agent motivate this interpretation. In two off‐line experiments in which comprehension scores and liking ratings were collected, we found that participants preferred natural agents with natural voices, as predicted by the social‐cue hypothesis. Although female agents with male voices formed an exception, this was explained by a stereotype effect. These findings support the social‐cue hypothesis and the social agency theory that human characteristics are applied in the perception of computational animated conversational agents.

Elder abuse and neglect are prevalent throughout the U.S. and are often unrecognized and untreated. It is projected that by the year 2030, the number of older adults (age 60 and older) will double, thereby increasing the likelihood that mental health practitioners will encounter instances of elder abuse and neglect. The authors address the symptoms, risk factors, consequences, current laws, interventions, and relevant prevention strategies related to these issues. 相似文献

Increasingly, the Internet is proving to be an important research tool. Today, cyberspace affords researchers easy access
to traditionally difficult to reach populations, a host of virtual communities, and a wealth of data created through computer-mediated-communication.
This newfound research frontier brings with it, however, a multiplicity of ethical concerns, including: (1) whether the Internet
constitutes a private or public space; (2) whether the human subject paradigm is appropriate when considering the ethics of
Internet research; and (3) whether cyber participants/‘speakers-as-writers’ and communities should be guaranteed confidentiality
and anonymity when researchers contain or consider them in research. This paper examines these specific ethical concerns as
they relate to Canada's Tri-Council Policy Statement: Ethical Conduct for Research Involving Humans, which, as yet, does not explicitly address ethics involved in Internet research. I propose that in large part the Internet
is by definition a public site of activity, and as such, many posters cannot expect their texts to remain confidential, nor
their names anonymous, and that the human subject paradigm is highly problematic in terms of regulating ethics involved in
some research generated through new information technologies. This is most expressly the case with computer-mediated-communication,
which, in light of the Tri-Council Policy Statement, can be viewed as theoretically akin to public entertainment and performance.

The purpose of this study was to investigate gender differences in problem-solving and conflict-resolution skills in preschool children. Children between 4 and 5 years of age completed 3 problem-solving tasks with either a same-sex or a different-sex peer. Children's verbal and nonverbal interactions were analyzed. Girls used mitigation more often than did boys. Mixed-sex dyads engaged in controlling verbal interactions more often than same-sex dyads. There were relationships between verbal and nonverbal behaviors and task success; these relationships also differed across pair types. The results of the study demonstrate that the gender differences in types of verbal interactions previously observed in preschool children's free play are also present in their problem-solving interactions and that children are able to alter the types of behaviors they use depending upon both partner gender and the type of task involved. 相似文献

It has recently been argued that the new B-theory of time argues invalidly from the claim that tensed sentences have tenseless truth-conditions to the conclusion that temporal reality is tenseless. But while early B-theorists may have relied on some such inference, new B-theorists do not. Giving tenseless truth-conditions for tensed sentences is not intended to prove that temporal reality is tenseless. Rather it is intended to undermine the A-theorist's move from claims about the irreducibility of tensed language to the conclusion that temporal reality must be tensed. I examine how A-theorists have used facts about language in attempting to establish their conclusions about the nature of temporal reality. I take the recent work of William Lane Craig, and argue that he moves illicitly from facts about temporal language to his conclusion that temporal reality is tensed. 相似文献

This study investigated associated-systems theory's prediction that interference with the visual or verbal mental systems should alter person impressions by removing or reducing the impact of the information represented within those systems, while accentuating the influence of other information. In Experiment 1, interference with the verbal system decreased the influence of verbal information on trait judgments and increased the influence of visual information on attractiveness and liking judgments. In Experiment 2, visual interference decreased the impact of visual information on attractiveness judgments and, at least for attractive targets, increased the impact of verbal information on trait and liking judgments. These results support the premise that impressions consist of representations allied with separate processing systems and that those impressions can be affected by other activities involving those systems. 相似文献

This article describes the process of theological reflection and the necessity of its practice in the formation of pastoral identity and development of ministry. Drawing upon the philosophy of C.S. Peirce, pastoral theology of the past twenty-five years, and the authors' clinical and classroom experiences, the essay illuminates the distinctive work of pastoral care givers that makes them unique in health care settings. 相似文献

There are two extant versions of the new tenseless theory of time: the date versionand the token-reflexive version. I ask whether they are equivalent, and if not, whichof them is to be preferred. I argue that they are not equivalent, that the date version isunsatisfactory, and that the token-reflexive version is correct. I defend the token-reflexive version against a string of objections from Quentin Smith. My defence involves a discussion of the ontological and semantic significance of truth conditions, and of the connection between truth and reality on the one hand, and that between truth and meaning on the other. I argue that Smith's objections to the token-reflexive theory stem from his confusing these two aspects of the notion of truth. 相似文献

The purpose of this research was to compare pay expectations of women and men. Participants were 371 college students (261 women, 110 men; 94% White) from a variety of majors. Most students at this university are middle class. Consistent with prior research, women estimated significantly lower salaries at career entry and peak and rated family considerations and pleasant working conditions as significantly more important than did men. Men and women differed on salary estimates for others, influence of salary on decision to enter a field, time off for childrearing, career certainty, and weekly work hours. Controlling for average salaries in the listed job, job characteristic importance, career path, and job input differences eliminated the gender differences at entry and reduced the difference at peak. 相似文献
