“…However, those participants who did not receive advanced information (unknown condition) appeared to initiate each response in anticipation of a moderate stimulus velocity and made adjustments within the response to achieve coincident timing. It could be argued that the constant stimulus velocity employed by Hart and Reeve simulated the known condition of Shea, et al (1981), while the random presentation of three stimulus velocities employed in this study corresponded to the unknown condition.…”

“…was employed in this study. According to Shea, Krampitz, Tolson, Ashby, Howard, and Husak (1981), the provision of information regarding the upcoming stimulus velocity in a coincident timing task influences the spatialtemporal structure of the response. Their data suggest that, when respondents were provided advanced information regarding the upcoming stimulus (known condition), they did not attempt to track the stimulus visually but merely adjusted the temporal duration of each response based on the reported timing errors.…”

This study examined the influence of two stimulus-presentation methods on coincident timing performance. 50 participants performed a button press and striking task in coincidence with a target stimulus. Participants were randomly divided into either the Terminating Group, whose target light was the last in the series, or the Apparent Motion Group, whose target was not the final light in the series and allowed the apparent motion of the stimulus to continue. 20 trials at each of three velocities, 4, 8, and 12 mph, were randomly performed for each task. The analysis yielded no significant differences between groups, indicating that coincident timing performance was not dependent on the method of stimulus presentation.

“…Authors concluded that participants were using the movement time of the target, as opposed to its velocity, to produce an appropriate aiming trajectory. Shea et al (1981) aimed at determining the relative impact of stimulus velocity and duration on the spatial-temporal structure and timing accuracy of simple coincident-timing responses (the “ballistic” and synchronized passing of the hand along photocells). They concluded that the stimulus velocity plays little or no role in determining the spatial-temporal structure on the timing accuracy of a simple coincident timing response, whereas our results (kinematic and temporal) showed exactly the opposite, stressing the definite priority of speed over exposure duration.…”

When intercepting a mobile object or an apparent movement, participants show a temporal bias. They are in advance when dealing with a slow-moving stimulus and late with a fast-moving one. We studied participants intercepting an apparent movement by sliding a disk on a table. Using a fast and a slow stimulus speed, we varied three factors: duration of presentation of the stimulus, distance covered by the stimulus, and speed context (constant or varied) of stimulus presentation. In addition to the temporal bus, spatial accuracy and kinematic measures were collected. The temporal bias created by speed was evident across all three factors. Speed, in addition to strongly determining the temporal bias, significantly affected the throwing strategy adopted by the participants, as revealed by latency, movement time, and disk trajectory duration.

“…Troisièmement, des facteurs contextuels peuvent interagir avec la vitesse et ainsi expliquer la controverse que retrouvée dans les écrits. La durée du stimulus est un facteur important à considérer lors de l’analyse des données de vitesse (Adams & Creamer, 1962; Adams & Xhignesse, 1960; Ball & Glencross, 1985; Shea et al, 1982). De plus, l’ordre dans lequel les conditions de vitesse sont présentées peut créer un biais systématique dans les résultats (Haywood; 1983, Haywood, Grennold, & Lewis, 1981).…”

“…L'apprentissage et la performance de taches d'AC peuvent etre influences par d'autres facteurs que la CR et la caracteristique de la reponse, et souvent ces facteurs sont en interaction. Ainsi, generalement, il est reconnu que la performance en AC s'ameliore avec l'age (Bard, Fleury, Carriere, & Bellec, 1981;Dorfman, 1977;Fleury & Bard, 1985;Haywood, 1977Haywood, , 1980Hoffman, Inwold, & Keller, 1983;Moujane, 1984;Shea, Krampit, Tolson, Ashby, & Howard, 1982), mais, il semble que cette amelioration soit monotonique. D'autres facteurs sont a clarifier au plan de la recherche en developpement.…”

RESUME Le but de cette etude est d'analyser les effets de la connaissance des resultats (CR), soit spatiale ou temporelle, sur la performance d'une tache d'anticipationcoincidence (AC) chez des enfants de 6, 8, et 10 ans. Trois groupes experimentaux ont ete formes pour chaque groupe d'age et les enfants ont ete repartis aleatoirement dans l'un ou l'autre de ces trois groupes. Durant des seances d'exercice, un groupe a recu une CR spatiale, un groupe une CR temporelle, et le troisieme groupe a realise la tache d'anticipation-coincidence sans aucune connaissance de resultats. En general, les enfants de 6 ans executent la tache moins efficacement que les enfants de 10 ans alors que les enfants de 8 ans constituent un groupe intermediaire. Dans l'ensemble, la CR spatiale ameliore la performance spatiale alors que la CR temporelle amene une deterioration de la performance spatiale sans avoir d'effet sur la performance temporelle. De plus, les enfants a qui est fournie une CR spatiale sont moins infuences par les effets perturbateurs de la vitesse du stimulus dans leur precision temporelle.
