5Statistical prediction alone cannot identify good models of behaviorBehavioral and Brain Sciences 46. 2023.The dissociation between statistical prediction and scientific explanation advanced by Bowers et al. for studies of vision using deep neural networks is also observed in several other domains of behavior research, and is in fact unavoidable when fitting large models such as deep nets and other supervised learners, with weak theoretical commitments, to restricted samples of highly stochastic behavioral phenomena.

18In search of lost time: Integrated information theory needs constraints from temporal phenomenologyPhilosophy and the Mind Sciences 3. 2022.Integrated information theory of consciousness proposes an identity between its causal structure and phenomenology. Through this assertion, IIT aims to explain consciousness by prioritizing first-person experience. However, despite its phenomenology-first stance, developments in IIT have overlooked temporality. As such, we argue that at present IIT’s phenomenological analysis is incomplete. In this critique, we show how IIT takes a non-identical illusionist stance towards the experiences of cont…Read more

5A wrinkle in and of time: Contraction of felt duration with a single perceptual switchCognition 225 (C): 105151. 2022.The way we represent and perceive time has crucial implications for studying temporality in conscious experience. Contrasting positions posit that temporal information is separately abstracted out like any other perceptual property through specialized mechanisms or that time is represented through the temporality of experiences themselves. To add to this debate, we investigate alterations in felt time in conditions where only conscious visual experience is altered through perceptual switches whi…Read more

15Hedonic impacts of gains versus losses of time: are we loss averse?Cognition and Emotion 35 (5): 1049-1055. 2021.A large part of our daily activities involves judging the psychological value of time. This study tested a previously less explored aspect about whether people are loss averse for time – i.e. do losses of time loom larger than corresponding gains? Using comparative hedonic judgments, the impact of prospective gains versus losses of time was examined for common contexts like waiting and local travel based on suggestions by typical navigation apps. The magnitude of time was varied without an expli…Read more

We employed a rapid serial visual paradigm in three experiments to investigate the...

29Proactive and reactive control depends on emotional valence: a Stroop study with emotional expressions and wordsCognition and Emotion 32 (2): 325-340. 2017.We examined proactive and reactive control effects in the context of task-relevant happy, sad, and angry facial expressions on a face-word Stroop task. Participants identified the emotion expressed by a face that contained a congruent or incongruent emotional word. Proactive control effects were measured in terms of the reduction in Stroop interference as a function of previous trial emotion and previous trial congruence. Reactive control effects were measured in terms of the reduction in Stroop…Read more

23Interdependence of attention and consciousnessIn Rahul Banerjee & Bikas K. Chakrabarti (eds.), Models of Brain and Mind: Physical, Computational, and Psychological Approaches, Elsevier. pp. 65-75. 2008.Research on attention has been closely linked with possible advances in the study of consciousness. Various theories and models have been proposed for attention in the past 50 years. Behavioural, computational, and neuroscientfic approaches have been successful in improving our understanding of attentional processes. Given the current status of attention research, what can we say about the relationship between attention and consciousness? This paper discusses the possible relationships between a…Read more

39Types of attention matter for awareness: a study with color afterimagesConsciousness and Cognition 18 (4): 1039-1048. 2009.It has been argued that attention and awareness might oppose each other given that attending to an adapting stimulus weakens its afterimage. We argue instead that the type of attention guided by the spread of attention and the level of processing is critical and might result in differences in awareness using afterimages. Participants performed a central task with small, large, local or global letters and a blue square as an adapting stimulus in two experiments and indicated the onset and offset …Read more

51Attribute preference and selection in multi-attribute decision making: Implications for unconscious and conscious thoughtConsciousness and Cognition 19 (2): 644-652. 2010.Unconscious thought theory (UTT) states that all information is taken into account and the attributes are weighted optimally resulting in better decisions in complex decision problems during unconscious thought. Very few studies have investigated the actual amount of information processed in the unconscious thought condition. We hypothesized that only a small subset of information might be considered during unconscious thought (like conscious thought). To test this possibility and to explore the…Read more

22Emotions help memory for faces: Role of whole and partsCognition and Emotion 23 (4): 807-816. 2009.The role of holistic or parts-based processing in face identification has been explored mostly with neutral faces. In the current study, we investigated the nature of processing (holistic vs. parts) in recognition memory for faces with emotional expressions. There were two phases in this experiment: learning phase and test phase. In the learning phase participants learned face–name associations of happy, neutral, and sad faces. The test phase consisted of a two-choice recognition test (whole fac…Read more

64Concentrative meditation enhances pre-attentive processing: A MMN studyNeuroreport 18 (16): 1709-1712. 2007.The mismatch negativity (MMN) paradigm which is an indicator of pre-attentive processing was used to study the effects of concentrative meditation. Sudarshan Kriya Yoga meditation is a yogic exercise practiced in an ordered sequence beginning with breathing exercises and ending with concentrative (Sahaj Samadhi) meditation. Auditory MMN waveforms were recorded at the beginning and after each of these practices for meditators and equivalently after relaxation sessions for the non-meditators. Over…Read more

204Mindfulness and the cognitive neuroscience of attention and awarenessZygon 45 (3): 627-646. 2010.Mindfulness can be understood as the mental ability to focus on the direct and immediate perception or monitoring of the present moment with a state of open and nonjudgmental awareness. Descriptions of mindfulness and methods for cultivating it originated in eastern spiritual traditions. These suggest that mindfulness can be developed through meditation practice to increase positive qualities such as awareness, insight, wisdom, and compassion. In this article we focus on the relationships betwee…Read more
