Children perform better on left than right targets in an ordinal task

Asymmetric number–space association leads to more efficient processing of congruent information in domestic chicks

“…Such an association in humans was previously attributed to formal instruction and culture (i.e., acquisition of reading and writing conventions). However, recent literature suggests that it is rather a shared and predisposed biological phenomenon, and this hypothesis is further supported by our study (Rugani and de Hevia, 2017;Aulet and Lourenco, 2018;McCrink et al, 2020;de Hevia, 2021;Rugani et al, 2022c). The valence hypothesis presented in the introduction could represent an example of hemispheric specializations at the basis of the SNA.…”

Magnitude shifts spatial attention from left to right in rhesus monkeys as in the human mental number line

“…This finding parallels data from children who showed better memory for left than right target positions (the cup under which a toy was hidden, in an array of ten horizontally arranged cups). 63 Left targets were likely associated with a left-to-right searching and right ones with a right-to-left searching. Higher accuracy on the left was explained by a more efficient left-to-right searching strategy in conditions that favored initial anchoring of attention to the most leftward cup, from which children initiated searching for the target.…”

“…Higher accuracy on the left was explained by a more efficient left-to-right searching strategy in conditions that favored initial anchoring of attention to the most leftward cup, from which children initiated searching for the target. 63 A visual processing advantage for the left space, supported by right hemispheric dominance, has been posited for processing global spatial-attentional 64 and quantity processing in infants 65 and newborns. 66 A left-to-right oriented attentional bias is especially pronounced when adults were asked to name the midpoint of numerical intervals without calculating, 49 , 50 , 57 , 67 , 68 and in ordinal tasks, in which Clark’s nutcrackers, domestic chicks, 19 monkeys, 20 and children 21 were required to identify always a specific position, e.g., the 4 th .…”

M²BRTPC: A Novel Modified Multimodal Biometric Recognition for Toddlers and Pre-School Children Approach

“…There has been research into child ngerprint recognition since 1899, when Galton published his rst paper [7]. Galton captured ngerprints of a single child using ink-on-paper from birth to the age of 4.5 years.…”

“…Most commonly used biometric traits for recognition systems such as ngerprint [7], iris [8], face [9], palmprint [10,11], and footprint [11,12] are often focused on adults. Aside from the fact that infants and young children's biometrics have a low rate of accuracy, another thing is that their physical features change as they grow.…”
