Background: In this study several aspects of attention were studied in 237 nearly 6-year-old twin pairs. Specifically, the ability to sustain attention and inhibition were investigated using a computerized test battery (Amsterdam Neuropsychological Tasks). Furthermore, the Teacher’s Report Form (TRF) was filled out by the teacher of the child and the attention subscale of this questionnaire was...

Attention is what allows one stream of information from the internal or external environment to be selected over others and therefore pervades almost any thought or action we take in our daily lives. It is little wonder then that defi cient attention, a common feature of many disorders of the brain (see Manohar, Bonnelle and Hunter (chapter 34), this volume; Vallar and Bolognini (chapter 33), t...

Introduction. The symptoms that comprise inattentive behaviour in ADHD include problems with focusing on a task and sustaining attention over a long period, even in advantageous external conditions. There is also a characteristic excessive distractibility under the influence of other, unimportant stimuli. Thus attention processes are one of the main variables which form the clinical picture of ...

The relational processes and practices that create sustain grassroots associations have received limited attention from researchers. This article addresses this gap, exploring collective leadership of through a ‘leadership-as-practice’ lens (Raelin, 2016a; 2016b). It adopts the concept ‘bundles’ practice (Schatzki, 2005) to analyse data single ethnographic case study. Adopting conceptual lens, ...

Of all tRNAs, initiator tRNA is unique in its ability to start protein synthesis by directly binding the ribosomal P-site. This ability is believed to derive from the almost universal presence of three consecutive G-C base (3G-C) pairs in the anticodon stem of initiator tRNA. Consistent with the hypothesis, a plasmid-borne initiator tRNA with one, two, or all 3G-C pairs mutated displays negligi...

Unhealthy behavior is responsible for much human disease, and a common goal of contemporary preventive medicine is therefore to encourage behavior change. However, while behavior change often seems easy in the short run, it can be difficult to sustain. This article provides a selective review of research from the basic learning and behavior laboratory that provides some insight into why. The re...
