ABSTRACT: Time perception and timing are typically understood and studied independently. I will discuss a proposal to integrate time perception and timing to understand temporal aspects of consciousness. This proposal postulates a hierarchy in which time is handled differently at different levels. In line with this, we have performed a study to understand the effect of a single perceptual change on perceived time. I will present the results from this study done using Necker cube, I will also discuss how different factors like intentions, attention, and social context influence our perception of time.

ABSTRACT: This talk begins by noting an unusual twinning that has occurred in the last decade or so within the social semantics of global space. The words ‘narrative’ and ‘toolkit’ have both firmly established their presence in public consciousness over the past few years. Why is this so? My talk suggests that there may in fact be hidden connections between the two apparently unrelated concepts of technology (emblematized by the ‘toolkit’) and language (displayed in one of its most powerful and flamboyant aspects as ‘narrative’ rather than simply as story). By way of sharpening a couple of conceptual differences between ‘story’ and ‘narrative’, I argue for certain fundamental linkages between tool-use and language-use that date back to prehistory and the way our mind/brains have evolved to conceptually process, thematically organise and emotionally absorb the world around us. These whispers from our ‘deep history’ could help explain our present addiction both to technology and to ‘post-truth’ narratives. In this sense, the talk returns us to a basic cognitive conundrum. Narratives are not, prima facie, the most efficient ways of transmitting information. Indeed, they often flaunt their fictive ‘lying’ nature. Yet narratives are discourse universals found in every known culture; they are persistently displayed in material art forms extending from Madhubani paintings to Louis Malle films to Internet memes. Again, why is this so? I postulate in this talk that the ‘toolbox’ of language in the early 21st century now contains a sophisticated range of tools (including syntactic embedding and repetition, auditory rhyming, metaphor, metonymy, hyperbole, irony and sarcasm etc. all the way up to pragmatic units of conversation such as speech acts) that are, for the most part, narratively embedded. These language devices have all been dizzyingly amplified by the technological revolution of which we are currently in the midst. In short, narrative, an ancient species-tool for cooperative communication and displays of efficacious causal reasoning has evolved into a powerful
interdisciplinary tool for virtually every sort of contemporary inquiry into ‘what makes us human’ from anthropology to zoology.

ABSTRACT: A large literature has documented violations of expected utility consistent with a preference for certainty (the “certainty effect”). We design a laboratory experiment to investigate the role of the certainty effect in explaining violations of the independence axiom. We use lotteries spanning over the entire probability simplex to detect violations systematically. We find that violations of independence consistent with the reverse certainty effect are much more common than violations consistent with the certainty effect. Results hold as we test robustness along two dimensions: varying the mixing lottery and moving slightly away from certainty.

ABSTRACT: Empirical evidence has affirmed that memory is an essential attribute of human cognition. Memory helps an individual in the storage and recollection of the relevant information. It was believed that memory is an accurate depiction of past scenarios; they are fixed entities like digital harddrive. Several studies have shown that the initial trace of memory is malleable, and with time, it gets robust and solidified. Once incoming information is encoded and stored, they are resistant to change or modification. Nevertheless, targeting the memory process after initial learning or upon reactivation is susceptible to modifications. Furthermore, memory is susceptible to modification because it needs maintenance and updating from time to time. In recent years, researchers have developed an interest in the alteration of memory. Updation of memory might help us in the development of therapeutic procedures towards pathological memories. Several paradigms have been used to date in memory modifications such as memory reconsolidation, pharmacological, neurostimulation, etc. In this talk, we will share the novel drug-free methodologies (i.e., memory reconsolidation and neurostimulation) in the treatment of pathological memories. In detail, memory reconsolidation mechanism, a process in which memory upon reactivation with a single cue becomes labile and malleable in nature. Moreover, in this talk, we will learn about the malleable nature of the reactivated memory and boundary conditions of memory reconsolidation. It is noteworthy here that not all memories undergo reconsolidation upon reactivation. Here, we will discuss the boundary conditions of memory.
ABOUT THE SPEAKER: Dr. Manish Kumar Asthana is an Assistant Professor at the Department of Humanities & Social Sciences, Indian Institute of Technology (IIT) Roorkee. Before joining IIT-Roorkee in 2019, Dr. Asthana was an associate professor at the Department of Psychology, Southwest University, Chongqing, China. He obtained his doctoral degree in 2013 at the University of Wuerzburg, Germany and post-doctoralship in social cognitive neuroscience at the Mackenzie Presbyterian University (Brazil) and Indian Institute of Technology Kanpur (India). His line of research has aimed to study pathological learning and memory mechanisms. The investigation of such processes has a highly significant biological impact. These processes represent a basic mechanism in an individual's adaptation to environmental changes and, consequently, the organism's homeostatic balance. He has conducted research mainly in the area of associative fear learning and its modulation. The development and introduction of novel methods such as behavioral, transcranial direct current stimulation, and genetics were the particular focus of his work. Other exciting research fields were investigations of early biomarkers for anxiety and related disorders, e.g., startle, skin conductance response (SCR), heart-rate variability, blood pressure, etc., for the assessment of early detection of anxiety or related disorders.

ABSTRACT: Since the Prague School linguists set out to define the distinctive features to describe speech sounds, phonological theory has been a rule-based system of mapping the input to the output through a series of rules. Optimality Theory proposed by Alan Prince and Paul Smolensky in 1993 was a radical shift away from this step-by-step mechanism. Merging together the concepts of harmonic grammar with the theoretical insight that phonological changes reduce markedness, their constraint- based evaluative mechanism, has four salient points:
1. The two kinds of universal constraints; markedness and faithfulness.
2. Constraint interactivity is through mutual ranking.
3. The generative mechanism, GEN, produces unrestricted output candidates.
4. The evaluative mechanism, EVAL, delivers the form that matches the actual surface representation as the optimal output in one step by evaluating it in parallel with all other potential outputs.
In this talk, I will describe some of the challenges and recent progress associated with the second and third points. While doing so I will touch upon two of my recent theoretical works using Malayalam and Punjabi to discuss a) the difference between using weighted constraints and ranked constraints, and b) the difference between unrestricted GEN and harmonically bound GEN.

Abstract Action on global warming (climate change) is an exercise in cost-benefit analysis (CBA) where the costs of reducing heat trapping greenhouse gases (GHGs) reflect in the present but the benefits will appear in future. This talk will present a tool for CBA of climate policies, namely, integrated assessment models (IAMs). In particular it will analyse the Dynamic Integrated Climate Economy (DICE) model for which William Nordhaus received the 2018 Nobel Prize in Economics. The lecture will apply DICE to answer policy questions such as how GHGs should be reduced and at what rate. About the speaker: Shreekant Gupta is Professor, Department of Economics, Delhi School of Economics, University of Delhi and Adjunct Professor, LKY School of Public Policy, National University of Singapore. He has worked extensively on the economics of climate change and is co-author of several reports of the UN Intergovernmental Panel on Climate Change (IPCC). He also serves as Vice-President, Indian Society for Ecological Economics.
