“…The surface of the building prevents the object from being perceived, yet the object still exists, so that the observer expects to see it reappear. Despite the interruption in spatio-temporal continuity, the object continues to exist, pre-existing the moment of its apparition (permanence of anteriority), and persisting in time after its disappearance (permanence of posteriority; Becchio & Bertone, 2003).…”

Temporality enters our immediate experience as passage and becoming: the role time plays in the construction of a world of enduring entities tends to go unnoticed. This paper examines the relation between time and ontology in the context of unilateral neglect, a neuropsychological syndrome in which patients fail to perceive or respond to stimuli in the contralateral hemifield, behaving as if that half of space does not exist. Traditional models characterize neglect exclusively in spatial terms. Based on recent investigations suggesting abnormal temporal dynamics, here we highlight the impact of time factors on the presentation of the disorder. Neglect patients do not simply miss the presence of stimuli on the left: they also ignore the past as well as the future of neglected stimuli. We claim that, if this occurs, it is because time, and not only space, is impaired. Torino, 05/05/2006Dear Editor, We modified the manuscript in an attempt to achieve the top standard required for publication in Neuropsychologia. Reviewer 1The reviewers have answered most of my concerns to my satisfaction. However, there is still a onesentence paragraph on page 3, and the formatting appears to need revision on page 17.We would like to thank the reviewer for her/his careful review of our manuscript. We have now integrated the one-sentence paragraph on page 3. Formatting on page 17 has been revised.On page 10, there is a typing mistake: the word "that" should be replaces by "than" in the second to last paragraph.We apologize for the typing mistake. As requested we have now replaced "that". These bewildering behavioural manifestations clearly exhibit a spatial gradient: the patient behaves as if half of the space does not exist, failing to report, react or search for stimuli located in the space contralateral to the lesion. The spatial nature of neglect is manifest and, understandably, interest in research has focused on spatial mechanisms (Halligan, Fink, Marshall, & Vallar, 2003).Here, we intend to focus on a dimension that, although less evident, is nevertheless no less important in the presentation of the disorder: time.Compared with spatial cognition, little is known about the neuropsychology of time. In this paper we first summarize the results of recent investigations suggesting abnormal temporal dynamics in neglect. Next, we consider some of the empirical and theoretical issues raised by this evidence: do the temporal abnormalities observed in neglect reflect the impairment of a unique mechanism or do they arise in relation to different timing systems? Do temporal deficits in neglect relate to spatial distortions? A final concern relates to the contribution of temporal deficits to neglect per se, i.e. to the loss of awareness for contralateral stimuli and events characteristically observed in neglect patients. It is impossible for us -wrote Kant in the Critique of Pure Reason (1787) -to represent things outside space and time and this is because things appear to us as spatiotemporally connoted. Whereas previous work f...

“…When we think of time, we think of how events follow on from one another, we rarely consider that time enters in the constitution of a world of enduring entities (Becchio and Bertone, 2003). Neglect implies an impairment of temporal mechanisms, thus dramatically disclosing the link between time and ontology.…”

“…For example, spatial cues can be used to individuate objects since observing two objects next to each other indicates that the two objects are not the same [12]. Humans also use temporal cues, e.g., they assume that an object would remain the same object over the course of contiguous manipulation or observation [13]. Most importantly, such spatial and temporal cues can inform the observer that the featural differences between the objects are not due to noisy observations, but due to the two objects being different [2], [12].…”

Abstract-This paper proposes a theoretical model that enables a robot to partition its unlabeled sensorimotor experience with different objects into discrete clusters, each corresponding to a specific object. To solve this object individuation problem, the robot was trained to detect whether two perceptual stimuli were produced by the same object or by two different objects. The model was tested using a large-scale experiment in which a humanoid robot explored 100 different objects by performing a variety of exploratory behaviors on them and detecting the resulting sensory feedback from several sensory modalities. The results show that with a small amount of prior training, the robot's model was able to successfully individuate the objects with a high degree of accuracy.

O controle motor de deficientes mentais é alterado pela insuficiência de informações entre os comandos aferente e eferente. Este estudo teve como objetivo avaliar o perfil motor de crianças portadoras de deficiência mental de grau moderado. O grupo de estudo foi constituído por 20 crianças, ambos os sexos, entre 7 e 15 anos, alunos das APAEs dos municípios de Biguaçu e Palhoça/SC, em 2005. Para a coleta de dados foi utilizada a Escala de Desenvolvimento Motor "EDM". O tratamento estatístico foi realizado com o programa Epi Info 6.0. A todas as habilidades motoras avaliadas foi atribuído nível "muito inferior". O quociente da motricidade fina obteve o menor déficit, sendo que ao quociente da organização temporal atribuiu-se o maior déficit. Tais resultados mostraram a estreita relação entre o potencial cognitivo e a conduta motora de deficientes mentais de grau moderado. Os déficits funcionais observados entre deficientes mentais podem ser conseqüentes à inadequação de suas habilidades psicomotoras, interferindo no desenvolvimento cognitivo, afetivo e social.
