Scientific LogAnalyzer: A Web-based tool for analyses of server log files in psychological research

Scientific LogAnalyzer is a platform-independent interactive Web service for the analysis of log files. Scientific LogAnalyzer offers several features not available in other log file analysis tools—for example, organizational criteria and computational algorithms suited to aid behavioral and social scientists. Scientific LogAnalyzer is highly flexible on the input side (unlimited types of log file formats), while strictly keeping a scientific output format. Features include (1) free definition of log file format, (2) searching and marking dependent on any combination of strings (necessary for identifying conditions in experiment data), (3) computation of response times, (4) detection of multiple sessions, (5) speedy analysis of large log files, (6) output in HTML and/or tab-delimited form, suitable for import into statistics software, and (7) a module for analyzing and visualizing drop-out. Several methodological features specifically needed in the analysis of data collected in Internet-based experiments have been implemented in the Web-based tool and are described in this article. A regression analysis with data from 44 log file analyses shows that the size of the log file and the domain name lookup are the two main factors determining the duration of an analysis. It is less than a minute for a standard experimental study with a 2 × 2 design, a dozen Web pages, and 48 participants (ca. 800 lines, including data from drop-outs). The current version of Scientific LogAnalyzer is freely available for small log files. Its Web address ishttp://genpsylab-logcrunsh.unizh.ch/.

Quiz-o-Matic: A free Web-based tool for construction of self-scoring on-line quizzes

Increasingly, educators are using the World-Wide Web (the Web) and related technology to supplement their traditional teaching materials. In this paper, we present a free tool that has been placed on the Web to enable educators to create Web pages that present self-scoring quizzes. Such Web-based practice quizzes provide students with an opportunity for interactive assessment and review of course material. The tool, Quiz-o-Matic, uses active server pages to build the HTML and JavaScript code for each quiz, without requiring the user to edit any code. We present evidence that students judge the self-scoring quizzes to be useful and worthwhile additions to a course.     

位置和内容对网页广告效果影响的眼动评估

使用TobiiT120型眼动仪,以16名大学生为被试,记录他们阅读嵌有网页广告新闻网页时的眼动注视过程,以探讨广告呈现位置、新闻内容与网页广告的相关性是否影响人们对网页广告的注视。实验采用3（广告位置：上方、中间、下方）×2（相关性：相关、不相关）两因素被试内设计。结果发现：（1）新闻内容和网页广告的相关性不影响人们对网页广告的加工;（2）对位于新闻上方和新闻中间的网页广告,被试的注视次数较多,且注视时间较长;（3）对位于新闻中间的网页广告,其再认效果优于位于新闻上方和新闻下方的广告。表明只有网页广告呈现位置这一因素影响被试对网页广告的注视。     

The Dragonfly’s Web: Courseware for children created by college students on the World-Wide Web

We describe a successful approach to teaching first-year undergraduates to produce World-Wide Web courseware. Students were responsible for coding, writing, graphics, research, and theory. We taught that courseware should elicit higher order cognitive processes such as problem solving, application, synthesis, and critical thinking in children. It appears that the exercise facilitated experiential learning, the application of theories of learning, and courseware and hypertext design, as well as promoting critical thinking in our undergraduates. We argue that psychology students can and should develop useful Web pages as a learning experience and service to the field.     

Lexique 2 : A new French lexical database

In this article, we present a new lexical database for French:Lexique. In addition to classical word information such as gender, number, and grammatical category,Lexique includes a series of interesting new characteristics. First, word frequencies are based on two cues: a contemporary corpus of texts and the number of Web pages containing the word. Second, the database is split into a graphemic table with all the relevant frequencies, a table structured around lemmas (particularly interesting for the study of the inflectional family), and a table about surface frequency cues. Third,Lexique is distributed under a GNU-like license, allowing people to contribute to it. Finally, a metasearch engine,Open Lexique, has been developed so that new databases can be added very easily to the existing ones.Lexique can either be downloaded or interrogated freely fromhttp://www.lexique.org.     

Tools for remote usability evaluation of Web applications through browser logs and task models

The dissemination of Web applications is extensive and still growing. The great penetration of Web sites raises a number of challenges for usability evaluators. Video-based analysis can be rather expensive and may provide limited results. In this article, we discuss what information can be provided by automatic tools able to process the information contained in browser logs and task models. To this end, we present a tool that can be used to compare log files of user behavior with the task model representing the actual Web site design, in order to identify where users’ interactions deviate from those envisioned by the system design.     

Experiential Learning and Social Justice Action: An Experiment in the Scholarship of Teaching and Learning

Abstract. This essay discusses the process and findings of an experiment on the scholarship of teaching and learning conducted in a religious ethics classroom that utilized an experiential approach to teaching and learning about social justice. The first part lays out the focus of the investigation and the pedagogical principles drawn from experiential learning theory that provided the foundation for the experiment. The second part describes all of the components of the pedagogical strategy used in the experiment, the social justice action project. The third part discusses the qualitative methodology used to gather evidence and the findings drawn from that evidence. What the evidence shows is that an experiential approach to teaching and learning about social justice can be quite effective. The essay concludes with discussions of areas for further study and the implications for the practice of others. (The survey described in this article can be found on the Wabash Center Web site〈 http://www.wabashcenter.wabash.edu/journal/glennon.html 〉).     

Equivalence of the statistics for replicability and area under the ROC curve

Two statistics, one recent and one well known, are shown to be equivalent. The recent statistic, p_rep, gives the probability that the sign of an experimental effect is replicable by an experiment of equal power. That statistic is equivalent to the well‐known measure for the area under a receiver operating characteristic (ROC) curve for statistical power against significance level. Both statistics can be seen as exemplifying the area theorem of psychophysics.     

Narcissism and social networking Web sites

The present research examined how narcissism is manifested on a social networking Web site (i.e., Facebook.com). Narcissistic personality self-reports were collected from social networking Web page owners. Then their Web pages were coded for both objective and subjective content features. Finally, strangers viewed the Web pages and rated their impression of the owner on agentic traits, communal traits, and narcissism. Narcissism predicted (a) higher levels of social activity in the online community and (b) more self-promoting content in several aspects of the social networking Web pages. Strangers who viewed the Web pages judged more narcissistic Web page owners to be more narcissistic. Finally, mediational analyses revealed several Web page content features that were influential in raters' narcissistic impressions of the owners, including quantity of social interaction, main photo self-promotion, and main photo attractiveness. Implications of the expression of narcissism in social networking communities are discussed.     

The shared online whiteboard: An assistance tool to synchronous collaborative design

IntroductionThe work presented in this paper comes from an industrial need for the development of new support tools for remote collaborative design. Within this framework, we present a literature review on this concept and propose the development of an online collaborative whiteboard.ObjectiveThis study aims to determine whether or not shared whiteboards can be used for remote design task collaboration, in conjunction with online chat interactions. It additionally seeks to discover if the organization of relationships and interactions within groups alter the structure of task completion.MethodThis tool was evaluated through the remote design task of a data structure diagram with data collected from 42 computer science students. This approach was carried out through students in triads, separated into different rooms who communicated via online chat and/or whiteboard. There were two variables in this experimental design, the presence or absence of a project leader and the sequencing of exchanges (each member asked permission to use the tool). This experiment aimed to determine whether the task requested could be performed and if similarities to a natural situation could be observed. Data was collected from actions performed on the whiteboard and chat interactions. The observations were conducted using a verbal interactions observation grid that was taken from a natural synchronous collaborative design situation. It included different dimensions such as cognitive synchronization, the proposal and evaluation of solutions and non-task oriented interactions.ResultsThe results show that the tool allows students to collaborate. A variety of behaviors can be observed in terms of whiteboard usage and chat interactions that depend on the experimental conditions. This study shows that the tool may be used in a natural situation and that group consciousness and coordination are very important factors in this type of task. It is clear that the nature of the chat interaction depends on the role of the subject within the group. We also observed a high level of non-task oriented communication, which was more than we expected.ConclusionThe shared online whiteboard designed in this study allows for the completion of a collaborative design task with different groups structures.

The adaptation of the Affective Norms for English Words (ANEW) for European Portuguese

This study presents the adaptation of the Affective Norms for English Words (ANEW; Bradley & Lang, 1999a) for European Portuguese (EP). The EP adaptation of the ANEW was based on the affective ratings made by 958 college students who were EP native speakers. Subjects assessed about 60 words by considering the affective dimensions of valence, arousal, and dominance, using the Self-Assessment Manikin (SAM) in either a paper-and-pencil or a Web survey procedure. Results of the adaptation of the ANEW for EP are presented. Furthermore, the differences between EP, American (Bradley & Lang, 1999a), and Spanish (Redondo, Fraga, Padrón, & Comesa?a, Behavior Research Methods, 39, 600–605, 2007) standardizations were explored. Results showed that the ANEW words were understood in a similar way by EP, American, and Spanish subjects, although some sex and cross-cultural differences were observed. The EP adaptation of the ANEW is shown to be a valid and useful tool that will allow researchers to control and/or manipulate the affective properties of stimuli, as well as to develop cross-linguistic studies. The normative values of EP adaptation of the ANEW can be downloaded at .     

Web-based experiment control software for research and teaching on human learning

In this article we describe some of the experimental software we have developed for the study of associative human learning and memory. All these programs have the appearance of very simple video games. Some of them use the participants' behavioral responses to certain stimuli during the game as a dependent variable for measuring their learning of the target cue-outcome associations. Some others explicitly ask participants to rate the degree of relationship they perceive between the cues and the outcomes. These programs are implemented in Web pages using JavaScript, which allows their use both in traditional laboratory experiments as well as in Internet-based experiments.
