Article
A growing collection of observations has demonstrated the presence of multiple neural oscillations participating in human temporal cognition and psychiatric pathologies such as depression and anxiety. However, there remains a gap in the literature regarding the specific roles of these neural oscillations during interval timing, and how these oscill...

Poor eating habits often lead to health concerns. While mental health conditions such as stress and anxiety have been linked as predictors for eating behaviors, cognitive factors may also contribute to eating practices during the early stages of the mandatory COVID-19 lockdown. In the current study, participants responded to a survey that asked the...
Article
The reported time of intent (W) and the reported time of action (M) have been used as indices of consciousness during simple voluntary actions. However, it is unclear whether W is exclusively inferred from M. Past studies have suggested that W is inferred from M by demonstrating that W varies when judged in conjunction with M. The current study off...
Preprint
The Striatal Beat Frequency model (Matell & Meck, 2004) suggests that multiple cortical oscillators contribute to human temporal cognition. Based on the theory, the current study examined the interactions between interval timing and neural oscillations, as predicted by timing deficits found in neuropsychiatric conditions. The interaction is predict...
Article
Mitigation plans during the early stages of COVID-19 provided a unique, antagonistic environment in which drastic changes occurred quickly and did so with minimal freedom of choice (e.g., involuntary transition from in-person to online classroom). As such, individuals of different beliefs and perspectives would respond differently to these mitigati...
Article
Full-text available
When we remember a city that we have visited, we retrieve places related to finding our goal but also non-target locations within this environment. Yet, understanding how the human brain implements the neural computations underlying holistic retrieval remains unsolved, particularly for shared aspects of environments. Here, human participants learne...
Article
Judging how far something is and how long it takes to get there is critical to memory and navigation. Yet, the neural codes for spatial and temporal information remain unclear, particularly the involvement of neural oscillations in maintaining such codes. To address these issues, we designed an immersive virtual reality environment containing telep...
Article
Full-text available
Past studies have employed the subjective experience of decision time (Libet’s W) as an index of consciousness, marking the moment at which the agent first becomes aware of a decision. In the current study, we examined whether the temporal experience of W affects subsequent experience related to the action. Specifically, we tested whether W influen...

Judging how far something is and how long it takes to get there are critical to memory and navigation. Yet, the neural codes for spatial and temporal information remain unclear, particularly how and whether neural oscillations might be important for such codes. To address these issues, participants traveled through teleporters in a virtual town whi...

Article
Hoerl & McCormack's dual systems framework provides a new avenue toward the scientific investigation of temporal cognition. However, some shortcomings of the model should be considered. These issues include their reliance on a somewhat vague consideration of “systems” rather than specific computational processes. Moreover, the model does not consid...
Article
The basis for how we represent temporal intervals in memory remains unclear. One proposal, the mental time line theory (MTL), posits that our representation of temporal duration depends on a horizontal mental time line, thus suggesting that the representation of time has an underlying spatial component. Recent work suggests that the MTL is a learne...
Article
Full-text available
Whether consciousness plays a causal role in cognitive processing remains debated. According to Benjamin Libet, consciousness is needed to deliberate and veto an action that is initiated unconsciously. Libet offered that the deliberation window takes place between the time of conscious intent (W) and action (MR). We further examined this deliberati...
Article
Full-text available
Although visual fixations are commonly used to index stimulus-driven or internally-determined preference, recent evidence suggests that visual fixations can also be a source of decisional bias that moves selection toward the fixated object. These contrasting results raise the question of whether visual fixations always index comparative processes d...

Although visual fixations are commonly used to index stimulus-driven or internally-determined preference, recent evidence suggests that visual fixations can also be a source of decisional bias that moves selection toward the fixated object (Krajbich et al, 2010). These contrasting results raise the question of whether visual fixations always index...
Article
The ability to limit distracter interference is an essential aspect of attentional control. However, the mechanisms by which we actively reject non-target objects that have already captured our attention (e.g., a tomato when looking for an apple) are unknown. We hypothesize that the ability to reactively reject non-targets depends upon the ability...
Article
Past studies have shown that the perceived time of actions is retrospectively influenced by post-action events. The current study examined whether rewarding performance feedback (even when false) altered the reported time of action. In Experiment 1, participants performed a speeded button press task and received monetary reward for a presumed "fast...
Article

Previous work suggested the association between intentionality and the reported time of action was exclusive, with intentionality as the primary facilitator to the mental time compression between the reported time of action and its effect (Haggard, Clark, & Kalogeras, 2002). In three experiments, we examined whether mental time compression could al...
Chapter
Is the moment of conscious decision (known as W), as timed by Benjamin Libet and colleagues, a measure of volition? This chapter discusses a new experiment showing that the perceived time of response (known as M) is also shifted by the same auditory cue that shifts W. The experiment showed that the strength of the tactile sensation of pressing the...

Authorship of a painting affects the evaluation of the artwork. In particular, prestigious authorship predicts an evaluation bias in favor of eminent artists. In the recent years, however, the art appreciation movement has focused attention on youth art. This reverse prestige bias effect raises a number of concerns about the virtue of art and the a...

A seminal experiment found that the reported time of a decision to perform a simple action was at least 300 ms after the onset of brain activity that normally preceded the action. In Experiment 1, we presented deceptive feedback (an auditory beep) 5 to 60 ms after the action to signify a movement time later than the actual movement. The reported ti...

We studied the responses of single neurons in the human medial temporal lobe while subjects viewed familiar faces, animals, and landmarks. By progressively shortening the duration of stimulus presentation, coupled with backward masking, we show two striking properties of these neurons. (i) Their responses are not statistically different for the 33-...

Place cells of the rodent hippocampus constitute one of the most striking examples of a correlation between neuronal activity and complex behaviour in mammals. These cells increase their firing rates when the animal traverses specific regions of its surroundings, providing a context-dependent map of the environment. Neuroimaging studies implicate t...
