1. Intermanual Transfer of Learning in a Fine Manual Skill Task
Abstract Intermanual Transfer of Learning (IMTL) is the ability to learn a certain skill in an easier way with one hand after that skill has been learnt by the opposite hand(1). This research aimed to investigate IMTL in a Fine Manual Dexterity (FMD) task in subjects presenting different Hand Preference (HP). The sample comprised 882 right and left-handers,

2. Dyslexia and hand preference in secondary school students
Research results with regard to handedness and dyslexia have been ambiguous. The present study investigated the relationship between handedness and dyslexia in secondary school students based on genetic (Right-Shift) and hormonal-developmental theories of handedness. A total of 135 students (45 dyslexics and 70 age- and sex-matched controls) participated in

3. Priming effect of figures that represent external objects or human body parts
A visual stimulus (e.g., a letter, word, or object) may have a lasting effect on the processing of subsequent stimuli. The present study verified the priming effect of a figure (i.e., five-petal daisy) on manual reaction time (MRT) to another equal or different five-petal daisy. Two distinct groups were tested. One group was instructed that the five-petal da

4. Relative growth in the fiddler crab Uca uruguayensis Nobili, 1901 (Brachyura, Ocypodidae) from Garças River mangrove, Guaratuba Bay, southern Brazil
A study on the relative growth was carried out in a population of the fiddler crab Uca uruguayensis from the mangrove of Garças River, Guaratuba Bay, Paraná State, southern Brazil. The dimensions analyzed were the length of the major chela (LMC) of males and width of the abdomen (AW) of females, because they are related to reproductive activities of waving

5. The correlation between lateralization of intracerebral hemorrhage in basal ganglia and handedness
PURPOSE: To investigate the correlation between lateralization of cerebral basal ganglia hemorrhage and handedness. METHODS: Medical records and computed tomography (CT) scans for 84 patients with primary hypertensive intracerebral hemorrhage (ICH) in basal ganglia were reviewed. Data of gender, age, handedness, and location of basal ganglia hematoma were st

6. Correlação entre atrofia hipocampal e déficit de memória em pacientes com epilepsia de lobo temporal mesial / Correlation between hippocampal atrophy and memory deficits in patients with mesial temporal lobe epilepsy
Mesial Temporal Lobe Epilepsy (MTLE) is the most common focal epilepsy in adults and is usually associated with hippocampal atrophy (HA) which is recognized by highresolution magnetic resonance imaging (MRI). It consists of a syndrome that is often refractory to clinical treatment and patients may have memory deficits due to hippocampal system damage, howeve

7. Left-right judgment of haptic stimuli representing the human hand
The handedness recognition of visually perceived body parts engages motor representations that are constrained by the same biomechanical factors that limit the execution of real movements. In the present study, we used small plastic cutouts that represented the human hand to investigate the properties of mental images generated during their haptic exploratio

8. Preferência manual e assimetrias intermanuais de desempenho na ação de alcançar em bebês / Manual preference and intermanual performance asymmetries in infants reaching
Manual preference has been regarded as derived from innate performance advantage of one hand over the other. The main purpose of this work was to investigate the relationship between manual preference and intermanual performance asymmetry on a task of reaching for static targets in five-month-old infants. Secondary purposes were to assess the effects of spat

9. Handedness of children determines preferential facial and eye movements related to hemispheric specialization
BACKGROUND: Despite repeated demonstrations of asymmetries in several brain functions, the biological bases of such asymmetries have remained obscure. OBJECTIVE: To investigate development of lateralized facial and eye movements evoked by hemispheric stimulation in right-handed and left-handed children. METHOD: Fifty children were tested according to handedn

10. Os Eeitos da idade sobre o padrão de assimetrias táteis, visuais e hemiespaciais em destros e canhotos / The Effects of age on patterns of tactile, visual, and hemispatial asymmetries in right- and left-handers
Em testes de bisecção de linhas horizontais, os indivíduos normais tendem a partilhá-las à esquerda do verdadeiro ponto zero, fenômeno este denominado de pseudonegligência. As investigações clínicas revelaram que os mecanismos de controle sobre a alocação de atenção ao lado esquerdo do corpo foram profundamente afetados quando houve lesão loca

11. Pseudonegligence, handedness and motor abilities in art and non-art students / Pseudonegligência, dominância manual e habilidades motoras em alunos das artes em comparação com alunos de outros cursos
Uma linha de pesquisa freqüente sobre a lateralização cerebral em artistas tem investigado o comportamento daqueles que sofrem de diversos síndromes neuropatológicas, afetando o hemisfério esquerdo ou direito. Em contraste, Bertrand (2001), observando que alguns poucos estudos reportaram um aumento na prevalência de canhotismo e ambidestrismo entre ar

12. Mental rotation of anthropoid hands: a chronometric study
It has been shown that mental rotation of objects and human body parts is processed differently in the human brain. But what about body parts belonging to other primates? Does our brain process this information like any other object or does it instead maximize the structural similarities with our homologous body parts? We tried to answer this question by mea
