Multiple-object tracking (MOT) involves keeping track of the positions multiple independent target items as they move among distractors. According to Pylyshyn (Cognition, 80, 127–158, 2001), item individuation mechanism used in MOT is also visually guided touch. To test this, we compared single-task (MOT alone) with dual-task while touching that changed colour), looking for interference: cases ...

Attraction to opposite-sex pheromones during rodent courtship involves a pathway that includes inputs to the medial amygdala (Me) from the main and accessory olfactory bulbs, and projections from the Me to nuclei in the medial hypothalamus that control reproduction. However, the consideration of circuitry that attributes hedonic properties to opposite-sex odors has been lacking. The medial olfa...

Motilin is an intestinal peptide that stimulates contraction of gut smooth muscle. The motilin receptor has not been cloned yet, but motilin-receptor agonists appear to be potent prokinetic agents for the treatment of dysmotility disorders. The aim of this study was to determine neural or muscular localization of motilin receptors in human upper gastrointestinal tract and to investigate their p...

1 R esum e: Nous pr esentons une nouvelle caract erisation des mots de Sturm bas ee sur les mots de retour. Si l'on consid ere chaque occurrence d'un mot w dans un mot innni r ecurrent, on d eenit l'ensemble des mots de retour de w comme l'ensemble de tous les mots distincts commenn cant par une occurrence de w et nissant exactement avant l'occurrence suivante de w. Le r esultat principal montr...

Homyk, Rodriguez and Weil (1976) have described T4 mutants, called sip, that partially suppress the inability of T4rII mutants to grow in lambda lysogens. We have found that mutants sip1 and sip2 are resistant to folate analogs and overproduce FH2 reductase. The results of recombination and complementation studies indicate that sip mutations are in the mot gene. Like other mot mutations (Mattso...

In the present study, we investigated whether peripheral vision can be used to monitor multiple moving objects and to detect single-target changes. For this purpose, in Experiment 1, a modified multiple object tracking (MOT) setup with a large projection screen and a constant-position centroid phase had to be checked first. Classical findings regarding the use of a virtual centroid to track mul...

OBJECTIVES To relate the cognitive parameters of systemic lupus erythematosus (SLE) patients in remission to their profile of autoantibodies. MATERIAL AND METHODS The study included 32 patients with SLE in remission, with mild disease activity as indicated by SELENA-SLEDAI < 6. For neuropsychological assessment, the Cambridge Neuropsychological Test Automated Battery (CANTAB) was applied, usi...

In the multiple object tracking (MOT) task, observers can typically keep track of up to four moving objects. Little is known however about the extent to which object motion is used by observers during MOT. For example, direction and speed might be used to anticipate future positions. We here ask to what extent position reports lag behind targets or instead correspond to extrapolated positions. ...

We have previously developed LAOS, a 5-layer adaptive authoring model for adaptive hypermedia, and LAG, a 3-layer adaptation model. Our primary goal is to integrate these two models and to reflect this integration as an extension of MOT, an on-line tool for adaptive hypermedia design. This paper focuses on the integration of LAG and LAOS, and the implications this integration has on the UM and ...
