Event Abstract Back to Event Distributed and overlapping neural bases for object individuation and identification Claire Naughtin1*, Paul Dux1 and Jason Mattingley1 1 The University of Queensland, School of Psychology, Australia To gain a sense of what, where and when visual information appears in our environment, we rely on two key processes known as object individuation and identification. In object individuation, spatial and temporal cues are used to register an object as a distinct perceptual event relative to other objects. In object identification, featural and related conceptual properties of a stimulus are extracted. It is currently unclear how these two processes are represented in the brain. We explored whether individuation and identification processes are underpinned by distinct neural substrates, and the extent to which brain regions involved in these two operations are consistent across encoding, maintenance and retrieval stages of visual short-term memory. Using functional magnetic resonance imaging we tested for brain regions that were sensitive to the number of physical objects (individuation) or the number of distinct object identities (identification) presented in a display. Across both univariate and multi-voxel pattern analyses, we found a large degree of overlap between these two processes in the brain. In addition, the brain regions recruited for each process varied across each stage of visual short-term memory. Our findings challenge influential models of multiple object encoding in VSTM which argue that individuation and identification are underpinned by a limited set of non-overlapping brain regions.

Worldwide, around 50 million people have dementia with symptoms including loss of memory, difficulty in thinking ability, issues with problem-solving and usage of language. About 1.2 million people provide specialised care for dementia patients throughout the world, but the number of trained dementia caretakers are low in India. Traditionally, the focus of medical research has been to find a plausible cure for dementia, while solutions to ease the lives of dementia patients, their caretakers, and their families are often neglected. This paper aims to design and develop a bio-engineering based assistive device- Memhans for patients suffering from the mild and moderate stage of dementia through the help of a case study, intensive design methodologies and prototyping skills. The prototype is an RFID based module integrating a GPS chip (for location tracking) with Bluetooth and a smartwatch app which has the function of relaxing the patient with music. It also provides notifications to the patient, their family, and their caretaker via respective smartphone apps and provides for a contextual understanding by `object and person identification'. This device provides the patient with assistance in daily activities, safety, person and object identification, and most importantly helps them live a dignified life. It also gives a sense of security and eases the minds of the caretaker and the patient's family. This device is cost-effective and is developed for a large number of impoverished patients who reside in developing countries like India.

Superior voice recognition in a patient with acquired prosopagnosia and object agnosia

Author's Introduction Our article outlines the need to bring together the literatures on personal and cultural identity – which have thus far been disconnected from one another. As one develops a sense of personal identity (e.g., goals, values, and beliefs), does one also develop a sense of cultural identity (e.g., how the individual and the group are prioritized, as well as attachment to and affiliation with one's ethnic, cultural, and national group)? This question is becoming increasingly important as Western countries become more and more diverse and multicultural, and as the world becomes more and more international and global. Individuals of European descent in the United States, Canada, Western Europe, Australia, and New Zealand, for example, are no longer insulated from other cultural streams. A generation ago, White Americans, for example, held dominion over the United States and over what ‘American culture’ was. With the advent of mass immigration of ethnic and cultural minorities, as well as globalizing technologies such as email, video conferencing, instant messaging, and virtual chatrooms, we are no longer insulated by our borders. Each of us is a citizen of the world, and this is becoming truer and truer over time. Thus, cultural identity and personal identity are increasingly likely to be related – and the ways in which they influence one another needs to be studied. How does my cultural position in my society (and in the world) influence who I am as a person? How do my cultural beliefs and worldviews influence my personal goals, values, and beliefs? Author Recommends Côté, James E., and Levine, Charles G. (2002). Identity formation, agency and culture: A social psychological synthesis . Mahwah, NJ: Lawrence Erlbaum Associates. This book discusses personal identity within the context of culture, and it clearly sets the stage for a discussion of how personal identity is affected by cultural processes. Arnett, Jeffrey Jensen. (2002). The psychology of globalization. American Psychologist , 57 , 774–783. This article discusses the ways in which globalization affects the personal and cultural identities of people around the world. In particular, the article stresses that individuals will be exposed to various cultural streams even if they never leave their countries of origin and do not come into direct contact with people from other parts of the world. The mass exportation of Western television programs, music, dress styles, fashion, and beliefs is leading people to ‘acculturate’ to Western values and behaviors. Bosma, Harke A., and Kunnen, E. Saskia. (2001). Determinants and mechanisms in ego identity development: A review and synthesis. Developmental Review , 21 , 39–66. This article reviews the ways in which personal identity is developed in ‘individualist’ and ‘collectivist’ contexts. In more individualistic contexts, personal identity is developed through active exploration of different alternatives, commitment to one or more of these, and an in‐depth evaluation of the commitment that has been made. In more collectivistic contexts, personal identity is developed through identification with the goals, values, and beliefs of significant others. This article was one of the first to address personal identity more broadly than through a Western lens. Matsumoto, David. (2003). The discrepancy between consensual‐level culture and individual‐level culture. Culture and Psychology , 9 , 89–95. This article argues that individualism and collectivism (and related constructs such as independence and interdependence) operate differently at the between‐individual level than at the between‐culture level. When studying the interface between personal identity and cultural identity, only individual‐level conceptions of cultural identity should be used. National‐level differences in cultural identity constructs tend to be fairly small – suggesting that most of the differences are between individual people.

This forthcoming handbook will consist of state‐of‐the‐art summaries and reviews from some of the leading identity scholars in the world. Chapters will focus on many different domains of identity, including personal and cultural identity but also including national, religious/spiritual, sexual, gender, social, and vocational identity. The book will be an important resource both for students and for professors interested in the field of identity.

Personal and national identities can play a pivotal role in understanding youth well-being in increasingly diverse societies. However, previous research has predominantly focused on Western contexts, overlooking youth from non-Western societies. Furthermore, there is a scarcity of research that simultaneously examined both personal and national identities in relation to well-being. To address this gap, this study focused on youth belonging to a majority group in Japan, confronting augmented cultural variations, and addressed relationships between personal and national identities and their links to well-being. This cross-sectional study included 968 university students in Japan aged 18-29 years (Mage = 20.06, SD = 1.17; 51.34% women) who identified their nationality as Japanese. Participants completed in 2016 self-report questionnaires, including measures of personal and national identity processes and well-being. Personal identity commitment and in-depth exploration were positively associated with national identity exploration and commitment, whereas personal identity reconsideration of commitment was positively associated with national identity exploration. Personal identity commitment and national identity exploration were positively related to well-being, and personal identity reconsideration of commitment was negatively related to well-being. This study contributes to understanding the interplay between personal and national identity processes and their relations with well-being among youth in a majority group outside Western countries. Given the importance of identity for young people's adjustment and for fostering their sense of social responsibility, this study may have significant practical implications for promoting both individual well-being and social cohesion.

This paper presents the iris recognition system for biometric personal identification using neural network. Personal identification consists of localization of the iris region and generation of a data set of iris images followed by iris pattern recognition. In this paper, a fast algorithm is proposed for the localization of the inner and outer boundaries of the iris region. Located iris is extracted from an eye image, and, after normalization and enhancement, it is represented by a data set. Using this data set a Neural Network (NN) is used for the classification of iris patterns. The adaptive learning strategy is applied for training of the NN. The results of simulations illustrate the effectiveness of the neural system in personal identification.

In this contribution, we review research that uses a cross-fertilisation approach to integrate developmental and social-psychological perspectives on how identities are formed and changed over time and how identity processes are genuinely social, being embedded in social contexts and fed by social contents. First, we outline the three-factor identity model as a parsimonious approach to understanding the dynamics of identity development. Second, we review empirical studies with longitudinal approaches to shed light on how identity processes are embedded in key contexts such as family, friendships and society at large through behaviours such as civic engagement. Third, we discuss the interplay between personal and social identities. We conclude by highlighting how adopting a cross-fertilisation approach that combines social-psychological and developmental perspective can significantly advance the theoretical understanding of identity dynamics. Finally, we address similarities and differences between personal identity and social identity approaches, and we provide an agenda for future research.

In this paper an improved face detection method based on our previous Information-Based Maximum Discrimination approach is presented that maximizes the discrimination between face and non-face examples in a training set without even using color or motion information. A short review of our previous method is given together with the description of the intuition behind and our recent improvement on its detection speed. A person identification system has been developed that performs multi-modal person identification in real-time video based on this newly improved face detection method together with speaker identification.

Many models of object identification are bottom-up and serial in nature; processing at a first stage needs to be complete before it is passed on to a subsequent stage, and there is no top-down feedback from the later to the earlier stages. However, data on picture identification in normal observers contradict a strict serial account of processing, since effects of variables on early and late stages of object identification combine in an interactive rather than an additive manner. Recent neuropsychological and functional anatomical data also indicate that object identification involves top-down activation of earlier stages of visual processing. In neuropsychological patients, subtle perceptual deficits can produce naming problems, even when there is good access to associated semantic knowledge; in functional activation studies, there is increased activity in visual processing areas when conditions require object naming relative to object recognition. These studies provide evidence that increased visual processing occurs in identification tasks, suggesting that there is re-current feedback during the identification process.

The notion of personal identity was originally a useful one in trying to make sense of the work the author do as a psycho-analyst. Of course there must be some individual variation between people, but the striking quality is the identicalness of their behaviour and their internal reactions. The distinction between personal identity and the process of identification, and the relations between these two distinct entities, are refined especially within the field of abnormal psychology. The effects of the institutions became obvious in the 1950s. Personal identity has been taken out of its glass case, as a specimen in museum-like isolation. In the network of relationships, an emotional state commenced with Dr A and flowed through a winding course, changing character and interacting with other anxieties, until it ended up as an activity of the institution. Personal identity is therefore problematic, and the author assertions have a lot of implications for philosophical and also everyday interests.

The increasing average human age and a growing number of old age population over the globe have emerged the need for automation in the health care domain. Eventually, health care robots will contribute to manage the workload of the care providers in the future health care domain. Elderly people face a major challenge to identify and pronounce names of daily use objects and different family and friends due to dementia-related issues. One of the many tasks by AI-Enabled elderly care humanoid robots will be communication with such patients. They will aid them to remember objects and persons they find difficult to identify and recognize due to dementia. This study has investigated the potential of the JD humanoid robot for object identification in such a scenario. The study has presented a prototype AI-Enabled elderly care robot that can aid elder persons to identify different objects. The robot is trained on ImageNet data set for object identification. Further, a personalized data set comprising of faces of different persons labeled by names of family and friends are also used to train robots for family recognition aid. The JD Humanoid robot captures an image of an object/person and also tracks it as the object/face moves. It identifies input images and outputs in audio format the name of the object/person to guide the elderly person. The third feature of the robot is the notifications of daily routine tasks for elder people like reminders for prayer, exercise walk, and medicine intake. Testing results have shown an object and person identification with 95% accuracy.

Tactile books for blind children generally contain tactile illustrations referring to a visual world that can be difficult to understand. This study investigates an innovative way to present content to be explored by touch. Following embodied approaches and evidence about the advantages of manipulations in tactile processing, we examined 3D miniatures that children explored using their middle and index fingers to simulate leg movements. This "Action simulations by finger gestures-ASFG" procedure has a symbolic relevance in the context of blindness. The aim of the present study was to show how the ASFG procedure facilitates the identification of objects by blind and sighted children. Experiment 1 examined the identification of 3D miniatures of action objects (e.g. the toboggan, trampoline) by 8 early blind and 15 sighted children, aged 7 to 12, who explored with the ASFG procedure. Results revealed that objects were very well identified by the two groups of children. Results confirmed hypotheses that ASFG procedures are relevant in the identification process regardless of the visual status of subjects. Experiment (control) 2 studied identification of tactile pictures of same action objects by 8 different early blind and 15 sighted children, aged 7 to 12. Results confirmed that almost all objects obtained lower recognition scores in tactile pictures than in 3D miniatures by both groups and showed surprisingly higher scores in blind children than in sighted children. Taken together, our study provides evidence of the contribution of sensorimotor simulation in the identification of objects by touch and brings innovative solutions in book design for blind people. Moreover, it means that only the ASFG procedure has a very inclusive potential to be relevant for a larger number of subjects, regardless of their visual skills.

The advanced systems of control and traffic management, which are part of the contemporary Intelligent Transportation Systems, are utilizing sophisticated technology enabling automatic license plate recognition. Systems of Automatic License Plate Recognition (ALPR) are used in the process of search for stolen vehicles, recording the time of entry of the vehicle, identification of users who violate road traffic regulations, etc. In each of these applications extremely important issue is the reliability and quality of data identification which are the basis for the detection of mentioned events. The basis of ALPR systems operation is the acquisition of data from the monitoring systems, which provide detection and identification of objects. Achieving the full functionality of the ALPR system requires consideration of factors that affect the efficiency of the image analysis as well as objects detection and identification processes. The main research problem considered in this paper is to analyse the impact of mentioned factors on the quality and reliability of the license plate recognition process.

Three experiments were conducted to determine whether encoding processes that support episodic memory for object location are distinct from those that support memory for object identity. Guided by transfer-appropriate processing notions, we examined with an incidental learning paradigm whether an attentional focus on object location at encoding promotes subsequent recovery of object location, whereas a focus on object identity promotes recovery of object identity. We found that judging spatial relationships at encoding selectively supports recovery of object location, provided the test assesses memory for these relationships (rather than absolute location); our results also showed that judging physical and semantic object attributes promotes recovery of object identity preferentially. Contrasting with these domain-specific effects was evidence that identification processes involved in object naming boost memory for object identity as well as for absolute object location. Object identification at encoding may support memory performance in both domains by triggering the binding of identity and location information through a mechanism of object-based attentional selection.
