Online data collection within social and behavioral research is burgeoning. For surveying individuals online, researchers
are increasingly relying on online panels and similar subject pools. phpPanelAdmin is a Web-based platform that is intended
to assist researchers in quickly setting up and managing an online panel. phpPanelAdmin solves many problems that can arise
when one is collecting data in online panels. As an open-source program placed under GNU General Public License, phpPanelAdmin
(www.goeritz.net/panelware) is not only free of charge but free of restrictions on its use, modification, and distribution.
Building a new online panel—which before required weeks and special skills—is now possible within minutes and at no cost.
Furthermore, phpPanelAdmin can be connected to an existing online panel or even be used for managing offline subject pools.
Functions include creating a panel sign-up form; automatically unfolding the panel database; searching for panelists; viewing,
modifying, and deleting panelists’ data; deleting and cloning variables; drawing samples; sending e-mail to panelists; exporting
data; displaying panel statistics at a glance; identifying duplicates; creating and managing e-mail templates; executing user-defined
SQL statements; and obtaining help. 相似文献

In the present article, functions written in the freeware R are presented that calculate several measures from traditional
signal detection theory for each individual in a sample, along with summary statistics for the sample. Bias-corrected and
accelerated bootstrap confidence intervals are also produced. Arguments are made for using an alternative approach—multilevel
generalized linear models—and a function is presented for it. These functions are part of the R package sdtalt, which is available
on the Comprehensive R Archive Network. Recent data from memory recognition studies are used to illustrate these functions. 相似文献

In the present study, we investigated three factors that were assumed to have a significant influence on the success of learning from multiple hypertexts, and on the construction of a documents model in particular. These factors were task (argumentative vs. narrative), available text material (with vs. without primary sources), and presentation format (active vs. static). The study was conducted with the help of the combination of three tools (DEWEX, Chemnitz LogAnalyzer, and SummTool) developed for Web-based experimenting. The results show that the task is the most important factor for successful learning from multiple hypertexts. Depending on the task, the participants were either able or unable to apply adequate strategies, such as considering the source information. It was also observed that argumentative tasks were supported by an active hypertext presentation format, whereas performance on narrative tasks increased with a passive presentation format. No effect was shown for the type of texts available. 相似文献

ABSTRACT— Although psychologists frequently use statistical procedures, they are often unaware of the statisticians most associated with these procedures. Learning more about the people will aid understanding of the techniques. In this article, I present a list of 10 prominent statisticians: David Cox, Bradley Efron, Ronald Fisher, Leo Goodman, John Nelder, Jerzy Neyman, Karl Pearson, Donald Rubin, Robert Tibshirani, and John Tukey. I then discuss their key contributions and impact for psychology, as well as some aspects of their nonacademic lives. 相似文献

Automatic stereotypes and emotional state can affect cognitive processes such as attention, perception, and memory. Two experiments were carried out to investigate whether anxiety and stereotypes of Middle Easterners influence attention and recognition memory in White participants. A dot‐probe procedure was used, with White and Middle Eastern faces as stimuli. The results showed that anxious participants who were exposed to terrorism‐related words showed a visual bias toward Middle Eastern faces, and were more accurate at recognizing both White and Middle Eastern faces. Non‐anxious participants, after exposure to the same primes, showed an attentional bias toward the White faces. Overall, participants were more accurate at recognizing the White faces than the Middle Eastern faces. Copyright © 2008 John Wiley & Sons, Ltd. 相似文献

How much a person is affected by postidentification feedback is dependent on the credibility of the person giving the feedback. Seven hundred and ninety participants across three experiments viewed a crime video, made judgments from a line‐up, were provided with co‐witness and/or outcome feedback (from police officers [high credibility] or children [low credibility]), and answered testimony‐relevant questions (e.g. How good a view did you get of the person in the video?). The aim was to find out how high versus low credibility co‐witness feedback affects a witness' retrospective judgments (Experiment 1) as well as estimations of these co‐witnesses' judgments (Experiment 2). Experiment 1 showed that the feedback effect was only observed when the co‐witness responses were attributed to a high credibility source. Experiment 2 showed that high credibility co‐witnesses were estimated to score higher on the testimony‐relevant questions as compared to low credibility co‐witnesses. Experiment 3 showed that outcome feedback (e.g. ‘you identified the suspect’) produces stronger effects on testimony‐relevant questions than co‐witness feedback. The implications of these findings are that when postidentification feedback is present, it is important to determine the source of this feedback. Copyright © 2008 John Wiley & Sons, Ltd. 相似文献

ABSTRACT— When two people witness an event, they often discuss it. Because memory is not perfect, sometimes this discussion includes errors. One person's errors can become part of another person's account, and this proliferation of error can lead to miscarriages of justice. In this article, we describe the social and cognitive processes involved. Research shows how people combine information about their own memory with other people's memories based on factors such as confidence, perceived expertise, and the social cost of disagreeing with other people. We describe the implications of this research for eyewitness testimony. 相似文献

If we adopt a virtue approach to epistemology, what form should the intellectual virtues take? In this paper, I argue that the proper structure of the intellectual virtues should be one that follows the tradition of internalism in epistemology. I begin by giving a general characterization of virtue epistemology and then define internalism within that framework. Arguing for internalism, I first consider the thought experiment of the new evil demon and show how externalist accounts of intellectual virtue, though constructed to accommodate our intuitions in such cases, cannot fully do so. I further argue that only adopting an internalist structure of the virtues will provide intellectual virtues that appropriately mirror the structure of the classical moral virtues. Finally, I argue that only an internalist structure of the virtues can explain why the intellectual virtues are valuable in themselves. 相似文献

The current study describes the development and validation of a new subscale to be used with the BIS/BAS scales (Carver & White, 1994). This subscale measures lowered approach motivation following nonreward. Factor analysis of the new subscale was carried out within a sample of 308 University students, test–retest reliability was established within a sample of 62 individuals, and construct validity was explored in a sample of 86 individuals by comparing scores on the new subscale with those on an existing self-report measure of apathy and on a behavioural measure of persistence. Reliability and validity of the new frustrative nonreward responsiveness subscale was found to be adequate within the populations studied. The findings are discussed in relation to theoretical accounts of BAS and BIS sensitivity. 相似文献

Many patients experience aspects of treatment and care as dehumanizing because the body is considered separate from the self and its life context. An attempt to transcend viewing persons in dualistic terms is posed by phenomenologists who focus not on "the body" as such but on what it means to be "embodied." In this paper, we review the relevance of the phenomenology of the body for health care and report the results of comparing Sally Gadow's phenomenological insights about body-self unity with a qualitative analysis of patients' accounts of satisfaction with the outcome of hand surgery. We illustrate the ways in which our findings were and were not congruent with Gadow's conceptualization of embodiment and highlight aspects that are ambiguous. We conclude that the body-self dialectical relationship should be recast as a body-self-society trialectic and discuss the implications of this new conceptualization for clinical practices. 相似文献
