Codes of online sexuality: Celebrity,gender and marketing on the web

Marketers use the combination of sex and celebrity to sell movies, music, and more. this qualitative project uses content analysis to track sexualized images on the official Web sites and fan sites of 41 celebrities. An official Web site may construct a celebrity’s sexuality as part of overall marketing, with all images as tightly controlled as trademarked images. Over time, these celebrity images become a public sexual iconography. While such images have been studied in other mass media, few studies have scrutinized sexuality on mainstream Web sites. This analysis finds that female musicians are more likely than other celebrities to be represented by sexualized images, and that all types of female celebrities are sexualized more than males. In general, a female celebrity who uses sexuality to promote her public image wears this sexuality like a uniform on both official and fan Web sites.     

A film set for the elicitation of emotion in research: A comprehensive catalog derived from four decades of investigation

Emotions are highly influential to many psychological processes. Indeed, research employing emotional stimuli is rapidly escalating across the field of psychology. However, challenges remain regarding discrete evocation of frequently co-elicited emotions such as amusement and happiness, or anger and disgust. Further, as much contemporary work in emotion employs college students, we sought to additionally evaluate the efficacy of film clips to discretely elicit these more challenging emotions in a young adult population using an online medium. The internet is an important tool for investigating responses to emotional stimuli, but validations of emotionally evocative film clips across laboratory and web-based settings are limited in the literature. An additional obstacle is identifying stimuli amidst the numerous film clip validation studies. During our investigation, we recognized the lack of a categorical database to facilitate rapid identification of useful film clips for individual researchers’ unique investigations. Consequently, here we also sought to produce the first compilation of such stimuli into an accessible and comprehensive catalog. We based our catalog upon prior work as well as our own, and identified 24 articles and 295 film clips from four decades of research. We present information on the validation of these clips in addition to our own research validating six clips using online administration settings. The results of our search in the literature and our own study are presented in tables designed to facilitate and improve a selection of highly valid film stimuli for future research.     

The Christian Reformed Church Periodical Index

Abstract

This article describes the creation of a web-based database that indexes less well-known periodical titles of importance to scholars in the Christian Reformed Church, and generally not covered by other indexing services. The author explains how the data from the index, originally stored in a card catalog, was moved online to a text-based system, and eventually into its present form in a web-based system. Highlighting some of the challenges that were overcome in creating this resource, brief details are provided on how the data are stored and retrieved in the web environment, on how the data are searched and presented to the researcher, and on the methods used to keep the database current.     

The effect of Twitter exposure on false memory formation

Social media sites such as Facebook and Twitter have increased drastically in popularity. However, information on these sites is not verified and may contain inaccuracies. It is well-established that false information encountered after an event can lead to memory distortion. Therefore, social media may be particularly harmful for autobiographical memory. Here, we tested the effect of Twitter on false memory. We presented participants with a series of images that depicted a story and then presented false information about the images in a scrolling feed that bore either a low or high resemblance to a Twitter feed. Confidence for correct information was similar across the groups, but confidence for suggested information was significantly lower when false information was presented in a Twitter format. We propose that individuals take into account the medium of the message when integrating information into memory.     

Presentation and validation of the Radboud Faces Database

Many research fields concerned with the processing of information contained in human faces would benefit from face stimulus sets in which specific facial characteristics are systematically varied while other important picture characteristics are kept constant. Specifically, a face database in which displayed expressions, gaze direction, and head orientation are parametrically varied in a complete factorial design would be highly useful in many research domains. Furthermore, these stimuli should be standardised in several important, technical aspects. The present article presents the freely available Radboud Faces Database offering such a stimulus set, containing both Caucasian adult and children images. This face database is described both procedurally and in terms of content, and a validation study concerning its most important characteristics is presented. In the validation study, all frontal images were rated with respect to the shown facial expression, intensity of expression, clarity of expression, genuineness of expression, attractiveness, and valence. The results show very high recognition of the intended facial expressions.     

The perception of tactile distance: influences of body site, space, and time

Vibrotactile prostheses for deaf or blind persons have been applied to any number of different locations on the body, including the finger, wrist, forearm, abdomen, back, and nape of the neck. The discriminability of patterns presented by such devices can be affected by the acuity of the site of application and the resolution of the display. In addition, the mutual influences among stimuli close together in both space and time can affect percepts within a broad range of parameters. For example, consideration must be given to a variety of tactile illusions often associated with the spatial separations and the range of temporal intervals typically used in cutaneous communication displays. Experiments are reported in which magnitude estimates and cross-modality matches of perceived extent produced by pairs of vibrotactile taps presented to separate loci were obtained on three different body sites. Perceived distance was directly related both to the timing between the taps and to their physical separation. The findings show a consistent relationship to cortical magnification across body sites.     

Development of a facial-expression database of Chinese Han,Hui and Tibetan people

Recently, cross-cultural facial-expression recognition has become a research hotspot, and a standardised facial-expression material system can significantly help researchers compare and demonstrate the results of other studies. We developed a facial-expression database of Chinese Han, Hui and Tibetan ethnicities. In this study, six basic human facial expressions (and one neutral expression) were collected from 200 Han, 220 Hui and 210 Tibetan participants who lived in these regions. Four experts on each ethnicity evaluated the facial-expression images according to the expressions, and only those achieving inter-rater agreement were retained. Subsequently, 240 raters evaluated these images according to the seven emotions and rated the intensity of the expressions. Consequently, 2980 images were included in the database, including 930 images of Han individuals, 962 images of Hui individuals and 1088 images of Tibetan individuals. In conclusion, the facial-expression database of Chinese Han, Hui and Tibetan people was representative and reliable with a recognition rate of over 60%, making it well-suited for cross-cultural research on emotions.     

Safer road users: Investigating the influence of PRIME road markings on motorcycle rider behaviour

Innovative road markings for motorcyclists, designed as Perceptual Rider Information for Maximising Expertise and Enjoyment (PRIMEs) were installed on the approach to demanding left-hand bends at six trial sites and a comparison site across the West Highlands of Scotland. These road markings were presented as a series of ‘gateways’ to encourage safer riding. Video data were collected to measure motorcycle speed, lateral position, braking and use of the road markings, before and after the PRIMEs were installed. A total of 9,594 motorcyclists were observed. Across the six trial sites, statistically significant reductions in speed were observed (at three sites). Significant changes in lateral position were observed at the final PRIME gateway marking (at one site), and at the apex of the bend (at three sites). Reduced braking was observed at three sites and there was a statistically significant increase in the use of PRIME road markings across four of the sites. No statistically significant effects were observed at the comparison site. These findings are discussed in relation to sustained effects and aspects of the ‘Safe System’ approach that are relevant to reducing motorcycle casualties.     

A Web-accessible database of characteristics of the 1,945 basic Japanese kanji

In 1981, the Japanese government published a list of the 1,945 basic Japanese kanji (Jooyoo Kanjihyo), including specifications of pronunciation. This list was established as the standard for kanji usage in print. The database for 1,945 basic Japanese kanji provides 30 cells that explain in detail the various characteristics of kanji. Means, standard deviations, distributions, and information related to previous research concerning these kanji are provided in this paper. The database is saved as a Microsoft Excel 2000 file for Windows. This kanji database is accessible on the Web site of the Oxford Text Archive, Oxford University (http://ota.ahds.ac.uk). Using this database, researchers and educators will be able to conduct planned experiments and organize classroom instruction on the basis of the known characteristics of selected kanji.     

Diminishing incidence of Internet child pornographic images

Indecent images of children posted to web sites and newsgroups over a 4-yr. period were sampled. A significant decline in the number of such images posted was observed, probably accounted for by the pressure of groups opposed to the distribution of such exploitive material.     

Confronting Chaos: Migration Law Responds to Images of Disorder

This paper argues that in liberal nations migration law orders chaotic images and is an important site for the construction of national identities. Empirical illustrations are drawn primarily from Australia, but the thesis is applicable to all immigrant nations and also provides insights for the “Old World”. The argument proceeds by first examining the role of migration laws in liberal democratic societies. Building on this framework, it then looks at how Australian migration law responds to images of disorder outside the nation. Finally, it considers how migration law addresses disorder within the nation by reflecting a coherent picture of Australian national identity. This revised version was published online in June 2006 with corrections to the Cover Date.     

Detecting nonlinearity in psychological data: Techniques and applications

Modern graphical and computational techniques for detecting nonlinearity in psychological data sets are presented. These procedures allow researchers to determine the information complexity of temporal data, using physiological and psychological measurements, and to provide evidence for chaos in time series contaminated by measurement noise. Problems with noise reduction and appropriate experimental control, using surrogate time series, are discussed, and applications of the technology are illustrated, using response time, handwriting, and typing data sets. In an experimental application of appropriate nonlinear analysis procedures, the results of a time series prediction experiment confirm that some subjects are sensitive to chaos. In contrast to previous attempts demonstrating sensitivity to chaos, the experiment reported here employs surrogate series to control for linear stochastic aspects of the stimulus sequences, such as autocorrelation. Recommendations for the selection of appropriate software for performing nonlinear analyses are presented, including a comprehensive list of World-Wide Web sites offering such software.     

The use of digital video recorders (DVRs) for capturing digital video files for use in both The Observer and Ethovision

Before switching a laboratory from analog to digital, for the recording of video files for use in Noldus software such as Ethovision and The Observer, researchers need to proceed with caution. There are obvious advantages in moving to digital recording for behavioral work, including increased storage capacity; no requirement to purchase video tapes; immediate search by date, time, or event; digital images are of higher quality; ability to view study sites remotely by Internet connection; and “smart” features, such as motion detection. But before you throw away your time-lapse video recorders, time code generators, and video multiplexors, there are some important cautions to take account of. Some research groups have bought digital surveillance systems on the assumption that they work with Ethovision and The Observer, only to be disappointed. The vast majority of systems depend on proprietary compression software that must then be converted to work properly in Ethovision or The Observer.     

Consequences of brain tumour resection on emotion recognition

Emotion processing impairments are common in patients undergoing brain surgery for fronto-temporal tumour resection, with potential consequences on social interactions. However, evidence is controversial concerning side and site of lesions causing such deficits. This study investigates visual and auditory emotion recognition in brain tumour patients with the aim of clarifying which lesion sites are related to impairments in emotion processing from different modalities. Thirty-four patients were evaluated, before and after surgery, on facial expression and emotional prosody recognition; voxel-based lesion–symptom mapping (VLSM) analyses were performed on patients’ post-surgery MRI images. Results showed that patients’ performance decreased after surgery in both visual and auditory modalities, but, in general, recovered 3 months after surgery. In facial expression recognition, left brain-damaged patients showed greater post-surgery deterioration than right brain-damaged ones, whose performance specifically decreased for sadness and fear. VLSM analysis revealed two segregated areas in the left hemisphere accounting for post-surgery scores for happy (fronto-temporo-insular region) and surprised (middle frontal gyrus and inferior fronto-occipital fasciculus) facial expressions. Our findings demonstrate that surgical removal of tumours in the fronto-temporal region produces impairment in facial emotion recognition with an overall recovery at 3 months, suggesting a partially different representation of positive and negative emotions in the left and right hemispheres for visually – but not auditory – presented emotions; moreover, we show that deficits in specific expression recognition are associated with discrete lesion locations.     

Do visual images have gestalt properties?

Recent research has demonstrated that percepts and images share processing resources. A natural consequence of this evidence is to ask what kind of properties are shared by the two representational systems, i.e. images and percepts. To what degree, for example, do images share the complex organization of visual percepts?

This paper investigates whether percepts and images share Gestalt properties. Four experiments were conducted to study this hypothesis. In all experiments subjects were presented with an auditory message in which approximately 15 locations in a matrix were defined by giving the co-ordinates of the cells. Half of the stimuli presented some “good” form, whereas in the other half the locations of the pieces were scattered. Subjects were systematically less able to recall the locations of the random forms. Therefore, it could be argued that the “good” forms help in image construction, even though the elements were auditorily presented. Effects of varying presentation speed, order, and of requiring a mental rotation before recall support this conclusion.

Some future directions for global justice

The fields of global ethics and global justice have expanded considerably over the last two decades and they now cover a wide variety of topics. Given this huge range there are many areas that are ripe for important developments. In this commentary I identify some useful directions for promising exploration in the field of global justice. I argue that expanded dialogue networks would considerably enhance work in philosophy and be beneficial to other disciplines as well. I indicate also how we could develop work on allocating responsibilities for reducing global injustices in useful ways, by considering a wider range of considerations that give rise to responsibilities and expanding the scope of, and audience for, these discussions. I catalog some under-theorized topics that should get more philosophical attention (including the notions of complicity, exploitation, and corruption). In addition, I draw attention to the ways in which a journal such as this one could facilitate a number of important dialogue networks.     

Chess databases as a research vehicle in psychology: Modeling large data

The game of chess has often been used for psychological investigations, particularly in cognitive science. The clear-cut rules and well-defined environment of chess provide a model for investigations of basic cognitive processes, such as perception, memory, and problem solving, while the precise rating system for the measurement of skill has enabled investigations of individual differences and expertise-related effects. In the present study, we focus on another appealing feature of chess—namely, the large archive databases associated with the game. The German national chess database presented in this study represents a fruitful ground for the investigation of multiple longitudinal research questions, since it collects the data of over 130,000 players and spans over 25 years. The German chess database collects the data of all players, including hobby players, and all tournaments played. This results in a rich and complete collection of the skill, age, and activity of the whole population of chess players in Germany. The database therefore complements the commonly used expertise approach in cognitive science by opening up new possibilities for the investigation of multiple factors that underlie expertise and skill acquisition. Since large datasets are not common in psychology, their introduction also raises the question of optimal and efficient statistical analysis. We offer the database for download and illustrate how it can be used by providing concrete examples and a step-by-step tutorial using different statistical analyses on a range of topics, including skill development over the lifetime, birth cohort effects, effects of activity and inactivity on skill, and gender differences.     

Microcomputer graphics in psychological research

This paper discusses a methodology for psychological instrumentation in which requirements common to a spectrum of experiments are defined and implemented in a microcomputer system. The microcomputer may either stand alone or be used as an intelligent front end to a larger computer. In either case, experiments are described in a high-level implementation language. The advantages of this approach include reduced hardware and maintenance costs, increased reliability, and smoother operation by research personnel. A tutorial example is given of the design and construction of one such system used to present visual stimuli, including text, graphics, and simple animation, on a movable array of video monitors. Displays are produced by a Z80 microcomputer in response to commands from a larger host computer, in this case a PDP Lab/8e. Illustrations are given of three studies in progress; comparisons are made with special-purpose equipment built earlier. The microcomputer system is preferable from both a cost and management point of view.
