Book Description
Attentional biases (ABs) play a prominent role in the development and maintenance of clinically relevant symptoms of, for example, anxiety and depression. In particular, increased attentional orienting and preoccupation with biologically relevant and mood-congruent stimuli has been observed, suggesting that the visual-attentional system is overly sensitive towards threat cues and avoidant of cues of reward in these disorders. First, several experimental paradigms have been used to assess ABs, e.g., the dot probe task, the emotional stroop task, and the spatial cueing task amongst others. Yet, these paradigms are based on different theoretical backgrounds and target different stages of the attentional process. Thus, different paradigms provided converging as well as diverging evidence with regard to ABs. However, it is often not entirely clear to what extent this reflects real differences and commonalities, or is caused by differences in methodology. For example, behavioral reaction time data can only provide a snapshot of selective attention. Measuring event-related potentials, eye movements, or functional brain imaging data enables exploring the exact temporal and spatial dynamics of attentional processes. Moreover, neuroimaging data reveal specific cortical networks involved in directing attention toward a stimulus or disengaging from it. Second, ABs have been mainly discussed as symptoms of psychopathology, while results in healthy participants are still scarce; previous studies mostly compared extreme groups. However, a comprehensive theoretical and empirical account of ABs in psychopathology also requires a thorough account of ABs in the general healthy population. Moreover, the effect of gender, as an important contributing factor in processing of emotional stimuli, has also not been considered systematically in previous research. Third, a variety of stimuli has been used in the assessment of ABs. So far, mostly facial or word stimuli have been applied. However, in everyday life not only facial emotion recognition but also a fast evaluation of complex social situations is important to be effective in social interactions. Recent research started using more complex stimuli to raise ecological validity. However, the use of ecologically valid stimuli poses some methodological challenges and needs to be applied more systematically. The aim of this research topic is to integrate different paradigms and stimuli, addressing individuals from the whole range of the population continuum, and to apply different methodological approaches. It is intended to bring together expertise in stimulus selection, timing and implementing issues, advancing and broadening the overall understanding of ABs.

Book Description
4C’s; Communication, Commerce, Connectivity and Culture are the building blocks of an economy. How well an economy will grow or perform will depend on how strong these four pillars are. Communication leads to sharing of information among individuals. It is important for any business to have the right kind of communication channel. Commerce, provides goods and services for the society and its people. Connectivity provides the right infrastructure and system for those goods and services to reach the market. Lastly, culture helps to retain the indigenous value in those. SIMSARC 2018, organised by Symbiosis Institute of Management Studies, focussed on the aforementioned idea and invited eminent speakers from academia and industry, all over the world, to share their views on the importance of the 4Cs; Communication, Commerce, Connectivity and Culture for businesses and society. The conference had 4 sub-themes viz. Communication, Commerce, Connectivity and Culture which were the plenary sessions for the conference. The highlight of the “communication: Role of AI, Big Data and IoT in Business” track was the papers which were from broad range of Internet of things (IoT), big data, role of technology, Artificial Intelligence among other aspects of communication. The panel speakers gave insight as to how communication is important for business not only for across boundaries but within a country as well. Another session was on “Culture: An indigenous way” where speakers deliberated on the cultures prevailing in different organisations, countries and societies. From a ‘we together’ attitude in some country to a ‘me first’ attitude in the other, cultural similarities and dissimilarities across nations were discussed in this track. The session witnessed some relevant questions from the audience on issues of language barriers and its effect on businesses. Language and cultural barriers are something which are inevitable but one needs to be adoptive and should learn languages to mitigate these barriers. “Connectivity: Backbone for development” was another plenary discussion where increase in connectivity through various social media platforms such as Facebook, Twitter, WhatsApp was discussed and deliberated where the focus was whether human beings are still emotionally connected or not. The critical role of technology was emphasized along with importance of human to human interaction. No matter how much technology comes in play, human connections will never die as this was concluded by speakers as Technolgoy may not be able to take away the emotional connect. Another track, “Commerce: Fuel for economy” where the panellist spoke about growth, price discrimination, financial markets, inequality etc. Investor’s education is one of the most important aspect to take the investors to level where they understand financial market and this will help in investment activity in the market. Sustainability was another concern highlighted by the speakers and they pointed that policies should work towards attaining sustainability in the market and try to bridge the gap between skills and jobs available in the country. Researchers from all over the country, belonging to academic institutes and industry, presented their research ideas on the 4C’s. These research works ranged from digital transformation, IOT, team dynamics and organisation culture to infrastructural issues, e-commerce, banking and corporate governance, the research works presented covered a plethora of policy issues where each one of them is the need of the hour. The deliberations from renowned academicians who came from different parts of the world along with top industrialist, bureaucrats, entrepreneurs, NGOs immensely contributed to the existing bodies of work. They emphasized on the importance of right policies to promote communication, connectivity, facilitating commerce and preserving culture among societies. Overall, the conference witnessed a brainstorming session with scholars and experts and it surely did pave the way for future research.

Book Description
During the last three decades, there have been enormous advances in our understanding of the neural mechanisms of selective attention at the network as well as the cellular level. The Oxford Handbook of Attention brings together the different research areas that constitute contemporary attention research into one comprehensive and authoritative volume. In 40 chapters, it covers the most important aspects of attention research from the areas of cognitive psychology, neuropsychology, human and animal neuroscience, computational modelling, and philosophy. The book is divided into 4 main sections. Following an introduction from Michael Posner, the books starts by looking at theoretical models of attention. The next two sections are dedicated to spatial attention and non-spatial attention respectively. Within section 4, the authors consider the interactions between attention and other psychological domains. The last two sections focus on attention-related disorders, and finally, on computational models of attention. Aimed at both scholars and students, the Oxford Handbook of Attention provides a concise and state-of-the-art review of the current literature in this field.

Book Description
The emotional and behavioral symptoms associated with PTSD have been widely studied, but until recently, much less was known about neuropsychological aspects of the disorder. This volume brings together leading experts to synthesize current knowledge on how trauma affects the brain. Integrating compelling insights from neurobiology with clinical and cognitive perspectives, the book presents cutting-edge theoretical advances with major implications for assessment and treatment. Clearly written and well documented, the volume explores the emergence of neuropsychological dysfunction in specific trauma populations: children, adults, older adults, and victims of closed-head injury. Coverage encompasses a range of chronic problems with memory, attention, and information processing, including biases in the ways that PTSD sufferers attend to and remember emotionally relevant information, as well as how they encode and retrieve trauma-related memories. Throughout, authors back up their arguments with salient empirical research, highlighting key findings from functional neuroimaging and electrophysiology. Methodological dilemmas and controversies are also addressed, such as the challenges of studying a disorder with frequent psychiatric and medical comorbidities. Timely and authoritative, this comprehensive work provides vital knowledge for trauma specialists and other researchers and clinicians, including neuropsychologists, clinical psychologists, and psychiatrists. It will also be of interest to advanced students in these areas.

Book Description
This Handbook surveys existing descriptive and experimental approaches to the study of anxiety and related disorders, emphasizing the provision of empirically-guided suggestions for treatment. Based upon the findings from the Diagnostic and Statistical Manual of Mental Disorders (DSM-5), the chapters collected here highlight contemporary approaches to the classification, presentation, etiology, assessment, and treatment of anxiety and related disorders. The collection also considers a biologically-informed framework for the understanding of mental disorders proposed by the National Institute of Mental Health's Research Domain Criteria (RDoC). The RDoC has begun to create a new kind of taxonomy for mental disorders by bringing the power of modern research approaches in genetics, neuroscience, and behavioral science to the problem of mental illness. The framework is a key focus for this book as an authoritative reference for researchers and clinicians.

Book Description
The Cambridge Handbook of Applied Perception Research covers core areas of research in perception with an emphasis on its application to real-world environments. Topics include multisensory processing of information, time perception, sustained attention, and signal detection, as well as pedagogical issues surrounding the training of applied perception researchers. In addition to familiar topics, such as perceptual learning, the Handbook focuses on emerging areas of importance, such as human-robot coordination, haptic interfaces, and issues facing societies in the twenty-first century (such as terrorism and threat detection, medical errors, and the broader implications of automation). Organized into sections representing major areas of theoretical and practical importance for the application of perception psychology to human performance and the design and operation of human-technology interdependence, it also addresses the challenges to basic research, including the problem of quantifying information, defining cognitive resources, and theoretical advances in the nature of attention and perceptual processes.

Book Description
It is argued in this book that there are three major approaches to anxiety. First, there is anxiety as an emotional state. Second, there is trait anxiety as a dimension of personality. Third, there is anxiety as a set of anxiety disorders. What is attempted is to produce a unified theory of anxiety which integrates all these major approaches. According to this unified theory, there are four sources of information which influence the level of experienced anxiety: (1) experimental stimulation; (2) internal physiological activity; (3) internal cognitions, (e.g., worries); and (4) one's own behaviour. The unified theory is essentially based on a cognitive approach. More specifically, it is assumed that individual differences in experienced anxiety between those high and low in trait anxiety depend largely on cognitive biases. It is also assumed that the various anxiety disorders depend on cognitive biases, and that the main anxiety disorders differ in terms of the source of information most affected by such biases (e.g., social phobics have biased interpretation of their own behaviour). In sum, this book presents a general theory of anxiety from the cognitive perspective. It is intended that this theory will influence theory and research on emotion, personality, and the anxiety disorders. Correction notice: Christos Halkiopoulos should have been credited for his role as the inventor of the Dot Probe Paradigm and for the design and execution of the experiment discussed in C. D. Spielberger, I. G. Sarason, Z. Kulczar, and J. Van Heck (Eds.), Stress and Emotion, Vol. 14. London: Hemisphere.
