  1. Auditory priming of frequency and temporal information: effects of lateralised presentation.

    Laterality 12(6):507 (2007) PMID 17852702 PMCID PMC2582062

    Asymmetric distribution of function between the cerebral hemispheres has been widely investigated in the auditory modality. The current approach borrows heavily from visual local-global research in an attempt to determine whether, as in vision, local-global auditory processing is lateralised. In...
  2. Laterality in coiling behaviour of snakes: another interpretation.

    Laterality 12(6):536 (2007) PMID 17852698

    The direction of coiling was periodically recorded for two species of viperid snakes--copperheads (Agkistrodon contortrix) and cottonmouths (Agkistrodon piscivorus). Overall, neither species showed a significant preference for coiling in a particular direction. Only 1 of 22 snakes exhibited an i...
  3. Hippocampal asymmetry in serotonergic modulation of learning and memory in rats.

    Laterality 12(6):475 (2007) PMID 17852699

    The modulation of learning and memory after left or right microinjections of the selective 5-HT1A receptor agonist 8-OH-DPAT and of the 5-HT1A receptor antagonist NAN190 into the hippocampal CA1 area of male Wistar rats was studied. Microinjections of 8-OH-DPAT (1 microg) into the right or left ...
  4. Hemispheric asymmetries in feature integration during visual word recognition.

    Laterality 12(6):543 (2007) PMID 17852697

    Although the definitive source of the left hemisphere's superiority for visual word recognition remains illusive, some argue that the left (LH) and right (RH) hemispheres engage different strategies during early perceptual processes involved in stimulus encoding. In particular, it is proposed th...
  5. The influence of musical experience on lateralisation of auditory processing.

    Laterality 12(6):487 (2007) PMID 17852700

    The influence of musical experience on free-recall dichotic listening to environmental sounds, two-tone sequences, and consonant-vowel (CV) syllables was investigated. A total of 60 healthy right-handed participants were divided into two groups according to their active musical competence ("musi...
  6. Handedness in Great Britain.

    Laterality 12(6):559 (2007) PMID 17852703

    Two large British databases of handedness assessed by writing hand at 10-11 years of age were analysed by geographical region. Left-handedness was found to vary significantly across regions according to one survey but not the other. In both data sets, left-handed writing was significantly more f...
  7. Does Irish-dance training influence lower-limb asymmetry?

    Laterality 12(6):500 (2007) PMID 17852704

    Irish-dance is a dance form where asymmetry is required. This study investigated the influence of Irish-dance training on four lower-limb asymmetries by comparing 100 Irish-dancers and 100 non-dancers. All four asymmetries showed significant differences between the dancers and the non-dancers: t...
  8. A note on asymmetric use of the forelimbs during feeding in the European green toad (Bufo viridis).

    Laterality 12(5):458 (2007) PMID 17712715

    European green toads (Bufo viridis) were tested for one-sided forelimb lateralisation during prey ingestion, i.e., when pushing food into the mouth. Results showed that toads preferentially used their left forelimb to help themselves in the ingestion of living larvae. It is argued that previous ...
  9. Asymmetry of flight and escape turning responses in horses.

    Laterality 12(5):464 (2007) PMID 17712716

    We investigated whether horses display greater reactivity to a novel stimulus presented in the left compared to the right monocular visual field, and whether a population bias exists for escape turning when the same stimulus was presented binocularly. Domestic horses (N=30) were tested on three ...
  10. Evolution of hemispheric specialisation of antagonistic systems of management of the body's energy resources.

    Laterality 12(5):397 (2007) PMID 17712712

    Excellent and rich reviews of lateralised behaviour in animals have recently been published indexing renewed interest in biological theorising about hemispheric specialisation and yielding rich theory. The present review proposes a new account of the evolution of hemispheric specialisation, a pr...
  11. A note on motor laterality in plains zebras (Equus burchellii) and impalas (Aepyceros melampus).

    Laterality 12(5):449 (2007) PMID 17712714

    This observational field study used intermittent still photography to examine the distribution of motor laterality in images of two African grazing quadruped species: plains zebras (Equus burchellii) and impalas (Aepyceros melampus). Zebra images (n=708) had a laterality index of -6.21 and a Z-s...
  12. Linking children's neuropsychological processing of emotion with their knowledge of emotion expression regulation.

    Laterality 12(5):381 (2007) PMID 17712711

    Understanding of emotions has been shown to develop between the ages of 4 and 10 years; however, individual differences exist in this development. While previous research has typically examined these differences in terms of developmental and/or social factors, little research has considered the ...
  13. Fixation and attention control in lateralised target detection and free recall with words.

    Laterality 12(5):428 (2007) PMID 17712713

    The purpose of the present study was to test the hypothesis that lateralised target detection in the visual modality would produce results similar in magnitude, reliability, and validity to those obtained in the auditory modality with an analogue task. Thus, it was expected that it would produce...
  14. Lifespan trends of side bias in India.

    Laterality 12(4):302 (2007) PMID 17558813

    This study examines the (a) lifespan trends, (b) theoretical propositions, (c) factor structure, and (d) congruency among different forms of side bias in an Indian sample (N=3474) using the preference measure of handedness, footedness, eyedness, and earedness. An increase in dextral preference w...
  15. Task demands affect manual asymmetries in pegboard performance.

    Laterality 12(4):364 (2007) PMID 17558818

    Previous work by Bryden and Roy (1999) showed a larger performance difference between the hands for placing pegs into holes on the Grooved Pegboard test than for removing pegs from the holes. The authors argued that these data provided evidence of the importance of task demands in manual asymmet...
  16. Visual bisection of freely-viewed asymmetrical stimuli.

    Laterality 12(4):347 (2007) PMID 17558816

    When performing line bisection tasks, neurologically normal individuals exhibit leftward biases. Similarly, normals also exhibit leftward biases during judgements of brightness, numerosity, and size. However, when these same judgement stimuli are visually bisected, this results in rightward bise...
  17. Asymmetry of visually guided sexual behaviour in adult Japanese quail (Coturnix japonica).

    Laterality 12(4):321 (2007) PMID 17558814

    Sexually active adult Japanese quail (Coturnix coturnix japonica) were trained to run across either a left- or a right-turning runway to obtain sexual access to a conspecific of the opposite sex. The birds tested with only their right eye in use showed significantly higher latencies to complete ...
  18. Phonological and semantic processing of words: laterality changes according to gender in right- and left-handers.

    Laterality 12(4):332 (2007) PMID 17558815

    The ability of cerebral hemispheres to process language is influenced by multiple factors. The well-known right visual field advantage in word recognition in divided visual field tasks is affected by both intra- and inter-individual variables. For example, hemispheric linguistic abilities may va...
  19. A longitudinal study on hand use while building a tower.

    Laterality 12(4):356 (2007) PMID 17558817

    The aim of the study was to describe a developmental trend of hand use for picking up and stacking blocks from the age of 18 months to 7 years. A second aim was to determine whether there is a relationship between right-hand use while building a tower and manual laterality at school age. A total...
  20. Direction of hair whorl and handedness.

    Laterality 12(4):295 (2007) PMID 17558812

    We recorded the direction of hair whorl rotation in samples of male right- and non-right-handers. The data corroborate those of Klar (2003) in showing equal numbers of clockwise and anti-clockwise whorls in non-right-handers but an excess of clockwise whorls in right-handers. The findings suppor...
