This paper describes an in-class activity to introduce random assignment, paired data, and learning effect. The activity requires minimal materials, can be completed in a single class period, and is suitable for those using technology to conduct data exploration but can also be adapted for use in a technology-free classroom. The activity consists…

Vector cross product transformations are essential components in general physics. The numerous mnemonic devices catered towards each potential transformation result in confusion, defeating their purpose of reducing learning barriers. Therefore, a general mnemonic device, subject-environment interaction or the subject, is proposed to help students…

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…

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…

The use of the hand is a physiological sequence. The prehensile nature of the human hand is an evolutionary feature as is the freeing of the hands due to bipedalism. Kay Baker outlines of the human hand's significance to the mind as found in chapter 14 of the "Absorbent Mind." In this article, she has created lists that break down the…

In response to the comment by Vuoksimaa and Kaprio (2010) on our previous article on sex differences in left-handedness (Papadatou-Pastou, Martin, Munafo, and Jones, 2008), we carried out an additional meta-analysis to explore whether the widely observed tendency for rates of left-handedness to be greater among male than female individuals is also…

Gottlieb used naturalistic observations of normally occurring events in the life history of individuals for the purpose of discovering the role of experience in the development of species-typical behaviors. His research revealed the impact of self-generated experiences (particularly those experiences that were self-stimulated) in the establishment…

This paper estimates the effects of handedness on earnings. Augmenting a conventional earnings equation with an indicator of left-handedness shows there is a positive effect on male earnings with manual workers enjoying a slightly larger premium. These results are inconsistent with the view that left-handers in general are handicapped either…

Previous research has revealed a lack of planum temporale (PT) asymmetry in adults with autism. This finding is now extended to children and adolescents with the disorder. MRI scans were obtained from 12 children with autism and 12 gender, handedness and age-matched comparison participants. The volume of gray matter in the PT and Heschl's gyrus…

This book is written to support parents and practitioners who wish to understand movement and how it contributes to all aspects of learning--intellectual, social and emotional, as well as the movement/motor aspect itself. Moreover, as there is a huge increase in the number of children with movement learning difficulties (Keen, 2001), that is…

This article reports on the development of a screening checklist for identifying children who might have developmental coordination disorder (DCD), use of the checklist to determine incidence rates in East Kent (United Kingdom), and possible relationships between DCD and left-handedness and between DCD and self-concept.
