“…The rationale for our use of the procedure was based on the link between attention and the degree to which change blindness is induced (e.g., Rensink, O'Regan, & Clark, 1997;Smith & Schenk, 2008). If a stimulus has attentional priority, one should expect it to be less susceptible to change blindness than a stimulus that does not receive attentional priority (Cole, Kentridge, & Heywood, 2004;Pisella, Berberovic, & Mattingley, 2004;Ro, Russell, & Lavie, 2001;Scholl, 2000;Smith & Schenk, 2008. In Experiment 2, we used the one-shot variant of the procedure, in which the changed item occurred once only.…”

Theory of mind is said to be possessed by an individual if he or she is able to impute mental states to others. Recently, some authors have demonstrated that such mental state attributions can mediate the Bgaze cueing^effect, in which observation of another individual shifts an observer's attention. One question that follows from this work is whether such mental state attributions produce mandatory modulations of gaze cueing. Employing the basic gaze cueing paradigm, together with a technique commonly used to assess mentalstate attribution in nonhuman animals, we manipulated whether the gazing agent could see the same thing as the participant (i.e., the target) or had this view obstructed by a physical barrier. We found robust gaze cueing effects, even when the observed agent in the display could not see the same thing as the participant. These results suggest that the attribution of Bseeing^does not necessarily modulate the gaze cueing effect.

“…For example, social drug users are more likely to detect changes to drug paraphernalia in photographs than are non-drug users [22] and American football experts are better able to spot meaningful changes to football scenes than are novices [23]. Change blindness can also help determine the mechanisms and strategies used by patients with various visual deficits [24,25]. Work on change blindness has also helped at an operational level, refining concepts which were not previously well articulated.…”

Change blindness is the striking failure to see large changes that normally would be noticed easily. Over the past decade this phenomenon has greatly contributed to our understanding of attention, perception, and even consciousness. The surprising extent of change blindness explains its broad appeal, but its counterintuitive nature has also engendered confusions about the kinds of inferences that legitimately follow from it. Here we discuss the legitimate and the erroneous inferences that have been drawn, and offer a set of requirements to help separate them. In doing so, we clarify the genuine contributions of change blindness research to our understanding of visual perception and awareness, and provide a glimpse of some ways in which change blindness might shape future research.

“…Temporal abnormalities in neglect are revealed in temporal integration (Duhamel, Goldberg, Fitzgibbon, Sirigu, & Grafman, 1992;Heide, Blankenburg, Zimmermann, & Kömpf, 1995), as well as in temporal processing (Husain, Shapiro, Martin, & Kennard, 1997;Hillstrom, Husain, Shapiro, & Rorden, 2004) and in retaining information over time (Husain, Mannan, Hodgson, Wojciulik, Driver, & Kennard, 2001;Pisella, Berberovic, & Mattingley, 2004). One source of ambiguity is that these abnormalities are measured over a wide range of timescales, from milliseconds to seconds and minutes.…”

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...
