The perception of simultaneity between auditory and visual information is of crucial importance for maintaining a coordinated representation of a multisensory event. Here we show that the perceptual system is able to adaptively recalibrate itself to audio-visual temporal asynchronies. Participants were exposed to a train of sounds and light flashes with a constant time lag ranging from -200 (so...

This study examined the use of elicited imitation in investigating lexical development within a semantic domain. For this purpose the acquisition of reference to sequence and simultaneity by 3-5 year old children was examined. Three factors were proposed to account for the older in which lexical items within a semantic field are acquired: restrictedness of a lexical item, congruence with percep...

This paper presents a formal game-theoretic model to explain the simultaneity problem that has made it di cult to obtain unbiased estimates of the e ects of both incumbent and challenger spending in U.S. House elections. The model predicts a particular form of correlation between the expected closeness of the race and the level of spending by both candidates, which implies that the simultaneity...

Sign languages have two primary articulation tracts: the two hands. They also have secondary articulation tracts that can be partitioned: the nonmanuals. Thus multiple propositions can be conveyed simultaneously. We have attested at most four simultaneously articulated independent propositions in sign languages, and suggest that this limit follows at least partly from limitations on visual shor...

We present a bipartite partial function c̃Eq-negT , whose communication complexity is O ( (logn) ) in the model of quantum simultaneous message passing (Q‖,pub) and Ω̃(√n) in the model of randomised simultaneous message passing (R‖,pub). In fact, our function has a poly-logarithmic protocol even in the (restricted) model of quantum simultaneous message passing without shared randomness (Q‖), thus...

The simultaneity matrix is an × matrix of numbers. It is constructed according to a set of -bit solutions. The matrix element mij is the degree of linkage between bit positions i and j. To exploit the matrix, we partition {0, . . . , − 1} by putting i and j in the same partition subset if mij is significantly high. The partition represents the bit positions of building blocks (BBs). The partiti...

Membrane system computations proceed in a synchronous fashion: at each step all the applicable rules are actually applied. Hence each step depends on the previous one. This coarse view can be refined by looking at the dependencies among rule occurrences, by recording, for an object, which was the a rule that produced it and subsequently (in a later step), which was the a rule that consumed it. ...

BACKGROUND The timing at which sensory input reaches the level of conscious perception is an intriguing question still awaiting an answer. It is often assumed that both visual and auditory percepts have a modality specific processing delay and their difference determines perceptual temporal offset. METHODOLOGY/PRINCIPAL FINDINGS Here, we show that the perception of audiovisual simultaneity ca...

Recent studies have shown that the audio-visual synchrony is recalibrated after adaptation to a constant timing difference between auditory and visual signals (i.e. temporal recalibration). Here we investigated whether the temporal recalibration occurs for audio-visual speech using an off-line adaptation method. After 3 minutes of lag observation, the audio-visual synchrony is recalibrated towa...
