Global/local scoring modifications for the Rey-Osterrieth Complex Figure: Relation to unilateral temporal lobe epilepsy patients

Abstract

Observation of figural reproductions of right temporal lobe epilepsy (RTLE) patients have revealed overall configuration errors, whereas in left temporal lobe epilepsy (LTLE) patients, the global aspect of performance is generally preserved. This study compared performance of individuals with temporal lobe epilepsy (LTLE, n 5 83; RTLE, n 5 63) on a global0local modification of the Rey-Osterrieth Complex Figure Test (RCFT). In Phase I, neuropsychologists (n 5 6) and neuropsychology fellows (n 5 3) completed a survey identifying the global and local aspects of the RCFT. Questionnaire responses were used to categorize a list of global and local items (five global, five local) for re-scoring the protocols of TLE patients during study Phase II. Results showed that the RTLE and LTLE groups were not differentiated according to the global or local indices F(1,141) 5 .385; p 5 not significant. There were lower local scores for both groups in the copy F(1,142) 5 5.23; p 5 .024, immediate F(1,142) 5 445.26; p , .001, and delay trials F(1,142) 5 427.82; p , .001, indicating less retention of local information over time. Results suggest general declines in figural memory for local stimulus properties in both unilateral TLE groups. However, this relationship was weakened after controlling for global and local item verbalizability.

The Neural Substrates of Drawing: A Voxel-based Morphometry Analysis of Constructional, Hierarchical, and Spatial Representation Deficits

“…Our findings support the notion that visual processing errors are one of the potential mechanisms underlying drawing and copying deficits and subserved by cortical regions outside PPC. This is in agreement with earlier studies (Kuschner et al, 2009;McConley et al, 2006;Poreh & Shye, 1998) showing that global/local processing deficits are detrimental to drawing abilities in different patient groups.…”

“…A further spatial deficit that can impact on copying performance is the ability to process local and global aspects of form (Kuschner, Bodner, & Minshew, 2009;McConley, Martin, Banos, Blanton, & Faught, 2006;Poreh & Shye, 1998). Neuropsychological data from brain-damaged patients, using both complex figure copying and the identification of hierarchical figures as well as functional neuroimaging and TMS studies in healthy controls, suggest some degree of functional lateralization of local and global form processing.…”

Association between cerebral metabolism and Rey–Osterrieth Complex Figure Test performance in Alzheimer's disease

“…We observed trends suggesting that the global features were associated with posterior frontal, temporal, and some occipital regions of the right hemisphere, while the details had a more bilateral representation, and included regions of right prefrontal cortex. Some investigators have found support for a global/local dissociation in the ROCF (Kleinman & Gupta, 2008), while others have not (McConley, Martin, Banos, Blanton & Faught, 2006). It may be that the detailed elements as defined did not adequately represent local processing.…”

Asymmetrical white matter networks for attending to global versus local features

“…As visual objects fundamentally consist of hierarchically organized elements, drawing requires attention and representation of multiple levels of object arrangements, including both the overall (global) and local aspects of the scene ( Chechlacz et al., 2014 , Navon, 1977 ). Not surprisingly, deficits in the ability to process local and global aspects of form profoundly impact on figure copying performance ( Kuschner et al., 2009 , McConley et al., 2006 , Poreh and Shye, 1998 ).…”
