“…6c). This preference for targets located on the left hemispace could be ascribed to a bias in the allocation of attention, somewhat similar to that shown by humans and dubbed as "pseudoneglect" (Jewell & McCourt, 2000;Albert, 1973). Nevertheless, chicks' performance is also undeniably reminiscent of the human mental number line (Dehaene, 1993).…”

Studies on human infants, focused on the ontogenetic origins of knowledge, have provided evidence for a small set of separable systems of core knowledge dealing with the representation of objects, number, and space. We investigated core knowledge systems from a comparative perspective, making use of the domestic chick as a model system, and filial imprinting as a key to animal mind. Here, we discuss evidence showing precocious abilities in the chick for representing: (i) the cardinal and ordinal/sequential aspects of numerical cognition, and (ii) the distance, angle, and sense relations among extended surfaces in the surrounding layout. Some of the abilities associated with core knowledge systems of number and space were observed in the absence of (or with very reduced) visual experience, supporting a nativistic account of the origins of knowledge.

“…The meta-analysis of Jewell and McCourt (2000) found much larger effect sizes for pseudoneglect measured using landmark than manual (overt) bisection. One possible interpretation of this pattern is that the motoric component required on manual bisection tasks produces activations in the left hemisphere (particularly in right handed individuals) which has the effect of shifting attention rightward compared to the more perceptual landmark task.…”

“…However, the magnitude of these two biases may vary independently across individuals, which the baseline rightward bias being stronger in some individuals, perhaps related to known factors such as arm length (Longo & Lourenco, 2007) or characteristic activation asymmetries between the hemispheres (Levy, Heller, Banich, & Burton, 1983). This may contribute to the notorious person-to-person (and study-to-study) variability seen in bisection and landmark tasks (Jewell & McCourt, 2000).…”

“…To ascertain that the bisection bias observed in manual line bisection was not caused by the use of her left hand (for a review see Jewell & McCourt, 2000), GG was also subjected to a bisection verification task. For this purpose, the bisected lines of the manual bisection task were re-administered for verification.…”

“…To quantify the magnitude, the distance from the left side of the line to the subjective mark was measured for each line separately (with 0.5mm accuracy) and converted into a deviation score using the following formula (Schenkenberg, Bradford, & Ajax, 1980): In this way, a negative value is obtained when the subjective midpoint was located on the left of the objective midpoint, which (for long lines) is assumed to reflect inattention towards the right part of the line. GG"s average deviation score for the 2cm lines was 5% (SD=4%), for the 10cm lines -9% (SD=3%), and for the 20cm lines -6% (SD=2%).Subsequent testing showed that for all line lengths the deviations (marginally) differed from the results of the control subjects (2cm, ST:p=.039; 10cm, ST:p=.007; 20cm, ST:p=.067).To ascertain that the bisection bias observed in manual line bisection was not caused by the use of her left hand (for a review see Jewell & McCourt, 2000), GG was also subjected to a bisection verification task. For this purpose, the bisected lines of the manual bisection task were re-administered for verification.…”

This observation supported the intuitive idea that the processing of number and space are tightly linked. It is only in the last two decades, however, that the relation between numbers and space has become the subject of systematic investigation and now, about 100 years after Galton"s classical observation, it is widely accepted that the processing of numbers is intimately related to the processing of spatial information at both functional and anatomical levels (e.g. Dehaene, Piazza, Pinel, & Cohen, 2003;Fias & Fischer, 2005;Hubbard, Piazza, Pinel, & Dehaene, 2005; Umilta, Priftis, & Zorzi, 2007).One of the most convincing and robust phenomena that demonstrate the interaction between numbers and space is the SNARC-effect. When asked to indicate whether a number is odd or even with a left or right key press, participants tend to react faster to relatively small numbers (e.g. 1) with their left hand than with their right hand side, while they are faster to relatively large numbers (e.g. 9) when the responses are executed with the right hand side. Dehaene et al. (1993) called this finding the spatial-numerical association of response codes (SNARC) effect and postulated that it was attributable to the mental organization of numbers, taking the form of a horizontally oriented mental number line (MNL) with small numbers located on the left and large numbers on the right. Since then, this effect has been replicated in a wide variety of experimental tasks, for example, magnitude comparison (Brysbaert, 1995) or phoneme monitoring (Fias, Brysbaert, Geypens, & d'Ydewalle, 1996), for a re...
