Reversing characters (digits and letters) when writing, and complete mirror writing, raise one of the oldest and most mysterious questions in developmental and educational psychology: Why do five-year-old children write symbols (e.g., [reversed E] for E) they have neither learnt nor seen? Attempts to draw up a complete explanatory theory of…

This study investigated the influence of phonological word representations from both first language (L1) and second language (L2) on third language (L3) lexical learning in L1-dominant Spanish-English bilinguals. More specifically, we used event-related potentials (ERPs) to determine whether L1 Spanish and L2 English phonology modulates…

Because sign languages have two main articulators, signers simultaneously experience both possibilities and constraints in the articulation and perception of linguistic messages. Sign languages commonly convey different linguistic units with each hand, and additional information is conveyed in nonmanual signals. Meaningful perseverations (or sign…

Previous research has linked the concept of number and other ordinal series to space via a spatially oriented mental number line. In addition, it has been shown that in visual scene recognition and production, speakers of a language with a left-to-right orthography respond faster to and tend to draw images in which the agent of an action is…

The purpose of this study was to examine the experiences of left-handed school leaders during their elementary and secondary school years. Further, this study examined the impact of these experiences on leadership practices exhibited by left-handed school leaders. The researcher used a mixed methods approach to conduct this study. For the…

Previous research suggests that block adding, subtracting and counting direction are early forms of number-space mapping. In this study, an embodiment perspective on these skills was taken. Embodiment theory assumes that cognition emerges through sensory-motor interaction with the environment. In line with this assumption, it was investigated if…

Background: Every language has certain specific idiosyncrasies in its writing system. Cross-linguistic analyses of alexias and agraphias are fundamental to understand commonalities and differences in the brain organization of written language. Few reports of alexias and agraphias in the Spanish language are currently available. Aims: To analyse…

The brain asymmetry and contralateral control of the body by the left and right brain hemispheres is known (Crystal, 1997; Fromkin, 1998). It is widely accepted that language lateralization, damage to the left brain, Magnetic Resonance Imaging (MRI) Positron Emission Tomography (PET) and results show that the left brain is regarded as the language…

This study examines the development of hammering within an ontogenetic and evolutionary framework using motion-capture technology. Twenty-four right-handed toddlers (19-35 months) wore reflective markers while hammering a peg into a peg-board. The study focuses on the motor characteristics that make tool use uniquely human: wrist involvement,…

Writing, as a skill of correct graphic design, represents an activity which is very important in each individual's life and work, and the period of elementary school, when writing skills are mastered, is the period when special attention must be devoted to determinants that can affect the process of writing. Gender, literacy phase and writing…

Lateralization, which is also known as hand preference, and 2D:4D finger ratio is a sign of prenatal testosterone and known to be associated with strength. The aim of this study is to investigate the relationship between 2D:4D, lateralization and hand grip strength in relation to hand and forearm that are thought to be effective in handball in…

Several theoretical proposals tried to account for the meaning open-endedness of metaphors in literature and for the effortful process they trigger in readers. However, very few experiments have tackled the neurophysiological underpinnings of literary metaphor. Here we used Event-Related brain Potentials (ERPs) to explore the temporal dynamics of…

In this study, it's aimed to evaluate the relation between dominant and non-dominant hand perimeters and handgrip strength of basketball, volleyball, badminton and handball athletes. Totally 101 active athletes (49 females, 52 male), of the average age in female 20±1.42 years, in male 21±1.99 years, joined to this study. Height, body weight, BMI…

User interface (UI) design patterns for mobile applications provide a solution to design problems and can improve the usage experience for users. However, there is a lack of research categorizing the uses of design patterns according to users' hand dominance in a learning-based mobile UI. We classified the main design patterns for mobile…

Within-individual variability is such an apparent characteristic of infant handedness that handedness is believed to consolidate only in childhood. Research showed that manifest handedness is influenced by emerging postural skills (sitting, crawling, and walking). In this investigation, it was proposed that symmetric hand-use (tendency to acquire…
