This study developed and validated the contents of an inventory of global lateral preference (IPLAG) that can be applied as self-assessment which included representing everyday tasks and different dimensions of laterality, such as (a) hand preference, (b) foot preference, (c) trunk preference, (d) eye preference, and (e) ear preference. To validate the IPLAG, it was referred for evaluation of content by professional doctors in the area of Motor Behavior in Brazil. It was analyzed the coherence of the task with the lateral dimension proposed, the understanding of the statement in the proposed task, suggestions for modification in the description of the proposed tasks, also allowing the reviewers to suggest other tasks for the inventory, and other suggestions for the inventory improvement. The analysis of the suggestions from the reviewers was held in a quantitative manner, using absolute and relative frequency of the notes supplied by the evaluators, and qualitatively by a Likert scale established in the instrument provided to reviewers. Evaluators’ analyses pointed to the quality of IPLAG as a feature for assessing global lateral preference. Therefore, the IPLAG may be an interesting feature for research and practical diagnostic applications related to the different manifestations of human laterality.

Dyslexia may be a development disturbance in which there are alterations in visual-spatial and visual-motor processing, while obsessive-compulsive disorder (OCD) is a psychiatric disease in which there are alterations in memory, executive function, and visual-spatial processing. Our hypothesis is that these disturbances may be, at least partially, the result of a crossed eye and hand preference. In the present study 16 controls, 20 OCD (DSM-IV criteria) and 13 dyslexic adults (Brazilian Dyslexia Association criteria) were included. All had a neurological examination, the Yale-Brown scale for obsessive-compulsive symptoms application and the Zazzó evaluation for laterality, abridged by Granjon. Results showed a right hand preference for 100% of controls, 84.6% of dyslexics, and 75% of OCD patients and a right eye preference for 73.3% of controls, 69.2% of dyslexics, and 35% of OCD patients. The left eye preference was significantly higher in OCD when compared with the two other groups (p = 0.01) and the left hand preference of OCD patients (25%) was also significant when compared to Brazilian population (4%) or British population (4.5%). It is possible that this crossed preference may be partially the reason for visual-spatial and constructive disturbances observed in OCD.

179 8- to 12-yr.-old children received hand-preference, eye-preference, dichotic (digits and nonverbal sounds) tests, and the Wide Range Achievement Test. These data and those from previous studies suggest that brain organization for receptive language laterality can be predicted by familial handedness in conjunction with assessed hand-eye preference. A model of optimum functional ear laterality patterns within a given brain organization is advanced. For example, the “typical” pattern of a right-ear (left-hemisphere) advantage for verbal stimuli was associated with high achievement scores only for right-handed individuals with a family history of dextrality.

Abstract: This study developed and validated the contents of an inventory of global lateral preference (IPLAG) that can be applied as self-assessment which included representing everyday tasks and different dimensions of laterality, such as (a) hand preference, (b) foot preference, (c) trunk preference, (d) eye preference, and (e) ear preference. To validate the IPLAG, it was referred for evaluation of content by professional doctors in the area of Motor Behavior in Brazil. It was analyzed the coherence of the task with the lateral dimension proposed, the understanding of the statement in the proposed task, suggestions for modification in the description of the proposed tasks, also allowing the reviewers to suggest other tasks for the inventory, and other suggestions for the inventory improvement.

AbstractThe heritability of handedness, the most commonly investigated lateralised phenotype, has been consistently estimated to be ~25%. Handedness is linked to brain asymmetries such as hemispheric dominance for language and it has been associated to psychiatric and neurodevelopmental disorders. Here, we investigated the genetics of handedness as well as foot and eye preference and their relationship with neurodevelopmental phenotypes. Parental left-side preference increased the chance of an individual to be left-sided for the same trait, with stronger maternal than paternal effects (n ≤ 4,042 family trios from the Avon Longitudinal Study of Parents and Children (ALSPAC)). By regressing out effects of sex, age, and the first two ancestry-informative principal components, we transformed categorical phenotypes (right, mixed, left) into quantitative measures for single nucleotide polymorphism (SNP) based heritability (SNP-h2). We found moderate SNP-h2 for transformed measures of hand (.21) and foot (.28) but negligible SNP-h2 for eye preference (.02) or the untransformed categorical measures (n ≤ 5,931). Genomic and behavioural structural equation modelling (SEM) in ALSPAC and a twin cohort from Hong Kong (n = 366) identified a shared genetic factor contributing to hand, foot, and eye preference, but no independent effects on individual phenotypes. Higher polygenic risk scores (PRS) for ADHD and genetic predisposition towards lower IQ and educational attainment (EA) were associated with left hand preference. This finding supports the idea of a right-handedness advantage on neurodevelopmental outcomes. This is the largest study conducted to date for multiple lateralised measures in the same individuals. Our analysis demonstrates how quantitative multidimensional laterality phenotypes are better suited to capture the underlying genetic component than simple left/right binary traits.

The purpose of this study was to investigate informal phonological awareness measures as predictors of first-grade broad reading ability. Subjects were 91 former Head Start students who were administered standardized assessments of cognitive ability and receptive vocabulary, and informal phonological awareness measures during kindergarten and early first grade. Regression analyses indicated that three phonological awareness tasks, Invented Spelling, Categorization, and Blending, were the most predictive of standardized reading measures obtained at the end of first grade. Discriminant analyses indicated that these three phonological awareness tasks correctly identified at-risk students with 92% accuracy. Clinical use of a cutoff score for these measures is suggested, along with general intervention guidelines for practicing clinicians.

Summary: Marsh (1996) produced evidence that method effects associated with negatively worded items might be responsible for the results of earlier factor analytic studies that reported finding positive and negative self-esteem factors in the Rosenberg Global self-esteem scale ( Rosenberg, 1965 ). He analyzed data collected from children using a 7-item self-esteem measure. This report details attempts to replicate Marsh 's analysis in data collected from two samples of adults who completed the full 10-item Global Self-Esteem (GSE) scale. The results reported here are similar to those given by Marsh in so much as a correlated uniquenesses model produced a superior fit to the data than the simple one factor model (without correlated uniquenesses) or the often reported two factor (positive and negative self-esteem) model. However, whilst Marsh reported that the best fit was produced by allowing negative item uniquenesses to correlate with each other, the model that produced the best fit to these data was one that contained correlated positive item uniquenesses. Supporting his claim that differential responding to negative and positive self-esteem items reflects a method effect associated with reading ability, Marsh also showed that factors associated with negative and positive items were most distinct among children who had poor reading scores. We report a similar effect among a sample of older adults where the correlation between these factors was compared across two groups who were selected according to their scores on a test of verbal reasoning.
