Two types of representations can be used to specify spatial relations: Coordinate spatial relations representations specify the precise distance between two objects, whereas categorical spatial relations representations assign a category (such as above or below) to specify a spatial relation between two objects. Computer simulation models suggest that coordinate spatial relations representation...

We present a case (SE) with integrative visual agnosia following ischemic stroke affecting the right dorsal and the left ventral pathways of the visual system. Despite his inability to identify global hierarchical letters [Navon, D. (1977). Forest before trees: The precedence of global features in visual perception. Cognitive Psychology, 9, 353-383], and his dense object agnosia, SE showed norm...

We argue that a lineup is diagnostic to the extent that it reveals information from recognition memory that was not available from the eyewitness^ recall memory Accordingly, lineup diagnosticity is denned as the probability that an innocent suspect is identified by the witness when lineup members resemble the eyewitness's prelineup description. Navon (1990) argued that this definition underesti...

Holistic processing has been shown with both faces and words, but it is unclear how similar their underlying mechanisms are. In this study attention to global local features was manipulated the consequences for holistic word face were examined. On each trial participants presented two Navon figures told focus on either or level. Then they performed a composite task in which indicated whether ta...

This study was aimed to identify impaired attentional components in mild CHI patients. The CHI features taken into account were age (< or = 30 vs. > 30 years), loss of consciousness (yes vs. no), and time after injury (few days vs. some months). The groups tested were composed of 26 patients and 26 controls (matched for age, sex and education). Experiment 1 used a dual-task paradigm (Umiltà et ...

According to GLOMOsys (the GLObal versus LOcal processing MOdel, a systems account), an important distinction is that between a local and a global processing system: The former processes information in parts, the latter processes it globally. These systems can be activated by perceptual processing and carry over to subsequent conceptual processing, in particular to analytical and creative thoug...

Previous work has demonstrated that providing a verbal description of a wine impairs its recognition (Melcher and Schooler, 1996 Journal of Memory and Language 35 231 ^ 245). It was proposed that the effect was due to disruption of the perceptual memory by the verbalisation process as seen in face recognition. A similar impairment can be observed in face recognition after reading the small (loc...

In young adults, having a relatively long time perspective has been associated with a more abstract, holistic approach to cognitive tasks, as opposed to the more concrete, detailed approach associated with having a more limited or near-future focus ( Trope & Liberman, 2003). Here we studied the impact of age differences in temporal perspective on performance on a classic visual attention task (...

The purpose of the present study was to determine whether individuals with Asperger's disorder exhibit difficulty in switching attention from a local level to a global level. Eleven participants with Asperger's disorder and 11 age- and gender-matched healthy controls performed a level-repetition switching task using Navon-type hierarchical stimuli. In both groups, level-repetition was beneficia...

Navon letter tasks have been shown to affect subsequent face recognition performance. As such tasks are not likely to by carried out prior to a witness attending an identity parade this is unlikely to have much applied relevance. Here, however, it is explored how a range of puzzles that witnesses might engage in affect face recognition. Cryptic crosswords were found to have a detrimental effect...
