Holistic facial composite systems: are they compatible with witness recall?

Facial composite systems offer a particular challenge to human-computer interaction as they must facilitate several cognitively complex tasks and also aid communication between the operator and the witness. This paper presents the findings from a survey conducted with UK police composite operators that explored some of the issues involved in composite construction. A particular emphasis was placed on the information that witnesses report and its compatibility with both the composite system interface and the underlying construction method used by the system

Creating fair lineups for suspects with distinctive features

In their descriptions, eyewitnesses often refer to a culprit's distinctive facial features. However, in a police lineup, selecting the only member with the described distinctive feature is unfair to the suspect and provides the police with little further information. For fair and informative lineups, the distinctive feature should be either replicated across foils or concealed on the target. In the present experiments, replication produced more correct identifications in target-present lineups—without increasing the incorrect identification of foils in target-absent lineups—than did concealment. This pattern, and only this pattern, is predicted by the hybrid-similarity model of recognition

Disgust trumps lust:women’s disgust and attraction towards men is unaffected by sexual arousal

Mating is a double-edged sword. It can have great adaptive benefits, but also high costs, depending on the mate. Disgust is an avoidance reaction that serves the function of discouraging costly mating decisions, for example if the risk of pathogen transmission is high. It should, however, be temporarily inhibited in order to enable potentially adaptive mating. We therefore tested the hypothesis that sexual arousal inhibits disgust if a partner is attractive, but not if he is unattractive or shows signs of disease. In an online experiment, women rated their disgust towards anticipated behaviors with men depicted on photographs. Participants did so in a sexually aroused state and in a control state. The faces varied in attractiveness and the presence of disease cues (blemishes). We found that disease cues and attractiveness, but not sexual arousal, influenced disgust. The results suggest that women feel disgust at sexual contact with unattractive or diseased men independently of their sexual arousal

Do prosopagnosics have impaired spatial coding within or between objects?

Barton and Cherkasova (2005) tested within-object and between-object spatial abilities of patients with prosopagnosia and concluded that prosopagnosia is the result of within-object spatial impairment. The interpretation of these findings is difficult as Barton and Cherkasova\u27s (2005) experimental design involved a major confound of using smaller distances in the within-object task and larger distances in the between-object task. The present study used the same distances on between-object and within-object spatial discrimination tasks in an attempt to replicate the findings of Barton and Cherkasova (2005). Experiments 1 and 2 were designed to test within-object and between-object spatial processing of faces and objects, respectively, in prosopagnosia using the between-object spatial distances from Barton and Cherkasova (2005) while Experiments 3 and 4 tested these impairments using the within-object spatial distances from the original study. The experiments failed to find a difference in between-object and within-object spatial processing in a prosopagnosic

The use of photographic caricatures to examine the development of a perception of facial attractiveness

Throughout the human population, there is remarkable agreement as to what constitutes an attractive face. The consistency of attractiveness ratings across age, gender and culture has led to a search for an underlying construct that determines facial attractiveness. Langlois and Roggman (1990) proposed the average is attractive hypothesis arguing that facial attractiveness is determined by the level of averageness of facial features. Langlois and Roggman (1990) created composite faces to examine this hypothesis but their methodology was criticised, particularly because the technique used to create the composites tended to remove facial flaws and blemishes. This led to the argument that the increased attractiveness of the composite faces was the result of the smoothing of the faces rather than from their increased averageness. This study used photographic quality caricatures, which retain facial texture, to further examine the average is attractive hypothesis. From a digitised photograph, faces shifted away from the average by +18% and +36% (caricatures), and faces shifted closer to the average by -18% and -36% (anticaricatures) were produced. Along with the original photograph this provided five different versions of the same face varying only on averageness. Forty-eight of these face sets were created: six male and six female sets for the ages 6-, 8-, 10-year-olds and adults. Twenty participants in each of the age groups 6-, 8-, 1 0-year-olds and adults were asked to select the most and the least attractive face from each set. Examination of the mean caricature level chosen by each group found an overall preference for average faces providing support for the average is attractive hypothesis. The preference for average faces was present in the youngest age groups but the strength of the effect increased with age. There is, however, a suggestion that absolute averageness is not preferred, with some support for the idea of an optimum level of averageness

The Effect of Real-World Personal Familiarity on the Speed of Face Information Processing

Background. Previous studies have explored the effects of familiarity on various kinds of visual face judgments, yet the role of familiarity in face processing is not fully understood. Across different face judgments and stimulus sets, the data is equivocal as to whether or not familiarity impacts recognition processes. Methodology/Principal Findings. Here, we examine the effect of real-world personal familiarity in three simple delayed-match-to-sample tasks in which subjects were required to match faces on the basis of orientation (upright v. inverted), gender and identity. We find that subjects had a significant speed advantage with familiar faces in all three tasks, with large effects for the gender and identity matching tasks. Conclusion/Significance. Our data indicates that real-world experience with a face exerts a powerful influence on face processing in tasks where identity information is irrelevant, even in tasks that could in principle be solved via low-level cues. These results underscore the importance of experience in shaping visual recognition processes

Coloration in different areas of facial skin is a cue to health: The role of cheek redness and periorbital luminance in health perception

Looking healthy is a desirable trait, and facial skin color is a predictor of perceived health. However, skin conditions that cause dissatisfaction with appearance are specific to particular facial areas. We investigated whether color variation in facial skin is related to perceived health. Study 1 defined three areas based on color differences between faces perceived as healthy or unhealthy: the forehead, periorbital areas, and the cheeks. Periorbital luminance and cheek redness predicted perceived health, as did global skin yellowness. In Study 2, increased luminance and redness caused faces to be perceived as healthier, but only when the increase was in the periorbital and cheek areas, respectively. Manipulating each area separately in Study 3 revealed cheek redness and periorbital luminance equally increased perceived health, with low periorbital luminance more negatively affecting perceptions. These findings show that color variation in facial skin is a cue for health perception in female faces

Law's Looking Glass: Expert Identification Evidence Derived from Photographic and Video Images

This article offers a critical overview of expert identification evidence based on images. It reviews the Australian case law and then, in an interdisciplinary manner, endeavours to explain methodological, technical and theoretical problems with facial mapping evidence. It suggests that extant admissibility jurisprudence and traditional safeguards associated with expert opinion evidence and the adversarial trial might not adequately protect those accused of committing criminal acts when they are confronted with incriminating expert identification evidence

보정어플을 통한 SNS 사용자들의 자기 표현

학위논문(석사) -- 서울대학교대학원 : 생활과학대학 의류학과, 2023. 2. 하지수.오늘날의 사회에서 기술의 발전은 문화와 생활 방식에 대한 접근 방식을 변화시켰고, 결과적으로 새로운 자기 표현 방식을 탄생시켰다. 이러한 변화의 중심에 소셜 네트워킹 플랫폼이 있는데 사람들이 오프라인보다 온라인에서 더 많은 활동을 하고 시간을 투자함으로써 전통적인 사회 구조와 상호 작용 방식이 달라졌다는 것을 쉽게 볼 수가 있다. 이러한 새롭게 변화된 온라인 환경에서, 보정과정을 거친 개인의 셀카는 다른 사람들과의 시각적 의사소통과 참여의 주요 매개체이다. 따라서 본 연구의 목적은 소셜 미디어에서 자신의 프레젠테이션을 지원하는 도구인 셀카와 사진 보정 앱 내의 표현 특성을 조사하는 데 있다. 연구는 총 세개의 연구문제로 이루어져 있으며 첫째, 소셜 미디어의 온라인 특성과 다른 사람과의 상호작용에 미치는 영향에 대한 조사는 온라인 미디어와의 개인적인 자기표현이 어떻게 작동하는지 이해하는 바탕으로, 앱을 사용하여 셀카를 편집하는 소셜 미디어 사용자의 근본적인 동기를 파악한다. 둘째, 소셜 미디어 사용자의 욕구에 특정 방식으로 영향을 미치는 다양한 요소들이 이러한 요소들이 사용자의 자아 이미지 표현에 대한 접근 방식을 어떻게 형성하는지 탐구한다. 마지막으로, 이상적인 '자기'에 대한 묘사에서 서로 다른 소셜 미디어 사용자의 다양한 욕구에 대한 더 깊은 이해를 얻기 위해 자기 개념 및 이미지와 관련된 특정 앱 기능과 자기 표현 방식 간의 상관관계를 조사한다. 방법론적 측면에서 질적 접근법을 선택하였으며, 위에 열거된 목적에 대한 자료를 수집하기 위해 총 20명의 한국 참가자를 대상으로 개별 심층 인터뷰를 실시하였다. 본 연구는 면접참여자 자신의 주관적 경험을 통해 이해하고자 하는 의미현상을 효과적으로 보존하고 있기 때문에 Giorgi의 서술적 현상학적 방법을 자료분석의 틀로 활용하였다. 분석된 자료의 결과는 사진편집 앱 사용동기 내 3개 범주(소셜미디어의 영향, 외모 가꾸기, 온라인 문화의 적응), 자기표현의 영향요인 내 5개 범주(자기결정 자율성 요인, 소셜미디어 매체 성격 요인, 개인적인 관점 요인, 소셜미디어 사용자 요인, 사회적 요인), 소셜 미디어 사용자의 자기 프레젠테이션 및 편집 셀카에 대한 접근 방식에서 공유된 일반 규칙 내의 네 가지 범주(진정성 있는 자기표션, '가짜'로 보일 것을 두려워하여 극단적인 편집을 피하는 행동, 일반적인 편집 관련 보정 규칙, 셀카 편집 도구의 자연스러운 활용방법), 추구하는 온라인 자기 이미지 내의 여섯 가지 범주(자연스러운 이미지, 내가 원하는 대로 삶을 사는 이미지, 다양하고 제한되지 않는 이미지, 호불호가 없어 다양한 사람들에게 호감을 사는 이미지, 상냥하고 다가가기 쉬운 이미지, 도시적이고 세련된 이미지)로 분류 된다. 본 연구의 결과는 전반적으로 사진편집 앱을 통해 매개되는 자신의 자기표현에 대한 시각지향적 소셜미디어 플랫폼의 역동성의 중요성뿐만 아니라 소셜미디어 사용자의 개별적인 자기 이미지 욕구가 어떻게 반영되는지에 대한 철저한 이해를 제공하기 부분에서 연구 의의가 있다.In today's society, advances in technology have transformed approaches to culture and lifestyles, resulting in a different mode of self presentation as well. Traditional social structures and modes of interactions have shifted, as individuals spend more time online than offline, with social networking platforms at the center of this change. Here, the used of edited selfies are the main mediums of visual communication and engagement with others. This studys objectives lie in the investigation of expressive characteristics within selfies and especially photo-editing apps, as tools to assist ones self presentation on social media. First, an inspection of the online nature of social media and its influence on interactions with others is used as a foundation to understand how personal self presentation with online mediums work, and also identify social media users underlying motivations for using apps to edit selfies. Second various factors that influence social media users desires be viewed in a certain way are explored, along with how these factors shape the users approaches to their expression of self-image. Lastly, the correlations between specific app features and ways of self-presentation in relation to self-concept and image are examined to gain a deeper comprehension on the diverse desires of different social media users in their portrayal of the ideal self. A qualitative approach in terms of methodology was chosen, in which individual in-depth interviews of a total of twenty participants from South Korea was conducted to gather data concerning the aims listed above. Giorgis descriptive phenomenological method was used as the frame for data analysis as it effectively preserves the meaning phenomena this study wishes to understand through interview participants own subjective experience. Results of analyzed data revealed three categories within photo-editing app usage motivations (influence of social media, polishing ones appearance, online acculturation), five categories within influencing factors of self presentation (self autonomy factors, nature of social media medium factors, personal perspective factors, social media user factors, socio-cultural factors), four categories within shared general rules of social media users in their approach to self presentation and editing selfies (authentic style of self presentation, avoiding extreme edits in fear of looking 'fake', general rules of edits, natural methods of selfie editing tool), and six categories in desired online self-image (natural image, living life as I want image, diverse and unrestricted image, crowd-pleaser image, amiable and easy-going image, urban and refined image) Overall, the findings of this study are of value as it provides a thorough understanding of not only the significance of the dynamics of a visual-oriented social media platform on ones self presentation mediated through photo-editing apps, but also how the distinct editing processes of social media users reflect of their individual self-image desires.Chapter I.

Review of Health Hazards and Toxicological Effects of Constituents of Cosmetics

Cosmetic products are designed for use on human body for beautifying and promoting attractiveness and appearance; for these reasons, cosmetics are in high demand especially among women of all ages in every country. Despite many vulnerabilities associated with cosmetic usage, the cosmetic and ‘makeup’ continues to enjoy wide acceptability irrespective of age and sex. This is made possible by massive advertising employed by producers and marketers of cosmetics. Advertising is the link between manufactured products and would-be consumers; it plays a crucial role in determining the product that is mostly patronised and vice versa. Therefore, ethical advertising that promotes utilitarian benefits of cosmetics should be encouraged over and above emotional advertisement that lowers self-esteem of consumers and offers such products as solution to their low self-esteem. Despite the ban in many countries of poisonous substances in cosmetic products, inexhaustive list of substances, such as lead, chromium, nickel, mercury, arsenic, cadmium, hydroquinone, steroids, nitrosamine, etc. are still present in many cosmetic products. In most cases, above regulatory values, cancers, renal disorders, thinning and easy brushing of the skin, dermatophyte infection with lesions, macular hyper pigmentation, pityriasis vesicular, diabetes mellitus, micropapular eruption, hypertension, etc. are possible toxicological and health hazards that may be associated with continuous cosmetic application
