The present report by Wood et al. (2006, this issue) invites us to reconsider what we should believe about the cognitive representation of numbers. Researchers interested in numerical cognition have quickly embraced the idea that systematic spatial performance biases in number-related tasks must reflect an inherent spatial attribute of the underlying cognitive representation of numbers. The association...
We investigated interhemispheric communication and hemispheric style differences (analytic vs. holistic) in two-digit Arabic number comparison by employing the divided visual field paradigm. Interhemispheric communication modulated two-digit number comparison in a very specific way. While no advantage of interhemispheric communication was found with unit-decade compatible trials (e.g., 52 and 67,...
Episodic memory was evaluated in patients with unilateral, frontal lobe damage and matched controls using a list- method directed forgetting paradigm. Directed forgetting instructions (forget vs. remember the word), encoding instructions (learn vs. judge the word) and test format (recall vs. recognition) were manipulated in order to explore how variations in encoding and retrieval affect verbal memory...
Dehaene et al. (1993, Experiment 6) presented evidence that the mental number line is left-to-right oriented with respect to representational associations and not with respect to left and right hands. Here we tried to replicate the study of Dehaene et al. (1993) in a larger sample (n = 32) using four different stimulus notations (Arabic numbers, number words, auditory number words, and dice patterns)...
Lexical morphology involves two types of suffixes: inflectional suffixes, which have a grammatical function, and derivational suffixes with a word formation function. In this study, functional magnetic resonance imaging (fMRI) was used during processing of Italian derived and inflected words. In the derivational task, subjects were asked to produce nouns derived from verbs and from adjectives (e.g...
Number processing can evoke spatial representations and cause lateralized attention shifts. The article by Wood et al. suggests interesting considerations about the mental space of numbers by pointing to a difference between physical and numerical space processing. We read Wood et al.'s findings in a perspective that takes into consideration a currently debated issue, that is the relation between...
Behavioral research suggests that individuals with dyslexia may have exceptional skills in nonverbal cognitive processes, while genetic studies have noted that giftedness, high IQ and/or special talents tend to run in families. Taken together, these results suggest that persons within families (particularly offspring) may share similar cortical systems supporting those functions. Postmortem and in...
Neuropsychological dysfunction in multiple sclerosis (MS) patients is now a well-established clinical finding. We examined the entity of visual spatial neglect in demyelinating disease and its correlation to the functional and neuroradiological parameters. The phenomenon of visual spatial neglect was examined in 20 (5 male and 15 female) MS patients. Two different examination methods were used – the...
