  1. The Sense of Time.Gerardo Viera - 2020 - British Journal for the Philosophy of Science 71 (2):443-469.
    It’s often claimed in the philosophical and scientific literature on temporal representation that there is no such thing as a genuine sensory system for time. In this paper, I argue for the opposite—many animals, including all mammals, possess a genuine sensory system for time based in the circadian system. In arguing for this conclusion, I develop a semantics and meta-semantics for explaining how the endogenous rhythms of the circadian system provide organisms with a direct information link to the temporal structure (...)

  2. The Fragmentary Model of Temporal Experience and the Mirroring Constraint.Gerardo Viera - 2019 - Philosophical Studies 176 (1):21-44.
    A central debate in the current philosophical literature on temporal experience is over the following question: do temporal experiences themselves have a temporal structure that mirrors their temporal contents? Extensionalists argue that experiences do have a temporal structure that mirrors their temporal contents. Atomists insist that experiences don’t have a temporal structure that mirrors their contents. In this paper, I argue that this debate is misguided. Both atomism and extensionalism, considered as general theories of temporal experience, are false, since temporal (...)

    How Do Attention and Adaptation Affect Contrast Sensitivity?Franco Pestilli, Gerardo Viera & Marisa Carrasco - 2007 - Journal of Vision 7 (9).
    Attention and adaptation are both mechanisms that optimize visual performance. Attention optimizes performance by increasing contrast sensitivity for and neural response to attended stimuli while decreasing them for unattended stimuli; adaptation optimizes performance by increasing contrast sensitivity for and neural response to changing stimuli while decreasing them for unchanging stimuli. We investigated whether and how the adaptation state and the attentional effect on contrast sensitivity interact. We measured contrast sensitivity with an orientation-discrimination task, in two adaptation conditions—adapt to 0% or (...)

    Animals Are Not Cognitively Stuck in Time.Gerardo Viera & Eric Margolis - 2019 - Behavioral and Brain Sciences 42.
    We argue that animals are not cognitively stuck in time. Evidence pertaining to multisensory temporal order perception strongly suggests that animals can represent at least some temporal relations of perceived events.

  5. Temporal Mental Imagery.Gerardo Viera & Bence Nanay - 2020 - In Anna Abraham (ed.), The Cambridge Handbook of the Imagination. Cambridge, UK: pp. 227-240.
    Mental imagery is perceptual processing that is not triggered by corresponding sensory stimulation in the relevant sense modality. Temporal mental imagery is perceptual processing that is not triggered by temporally corresponding sensory stimulation in the relevant sense modality. We aim to show that temporal mental imagery plays an important role in explaining a number of diverse mental phenomena, from the thickness of temporal experience and the specious present to episodic memory and postdictive perception.

    The Perceived Unity of Time.Gerardo Viera - forthcoming - Mind and Language.
    While we perceive events in our environment through multiple sensory systems, we nevertheless perceive all of these events as occupying a single unified timeline. Time, as we perceive it, is unified. I argue that existing accounts of the perceived unity of time fail. Instead, the perceived unity of time must be constructed by integrating our initially fragmented timekeeping capacities. However, existing accounts of multimodal integration do not tell us how this might occur. Something new is needed. I finish the paper (...)
