In this short monograph, John Horty explores the difficulties presented for Gottlob Frege's semantic theory, as well as its modern descendents, by the treatment of defined expressions.

The book begins by focusing on the psychological constraints governing Frege's notion of sense, or meaning, and argues that, given these constraints, even the treatment of simple stipulative definitions led Frege to important difficulties. Horty is able to suggest ways out of these difficulties that are both philosophically and logically plausible and Fregean in spirit. This discussion is then connected to a number of more familiar topics, such as indexicality and the discussion of concepts in recent theories of mind and language.

Coordination problems often make everyday activities a challenge for children with learning disabilities. This accessible manual offers practical strategies and advice for helping children with coordination difficulties. The author explains how to recognize normal and abnormal motor development, when and how to seek help and includes specific teaching strategies to help children with coordination difficulties succeed in the classroom, playground and home. She describes a wide range of therapeutic methods and provides a comprehensive list of resources.

This book examines the mathematical difficulties in typical and atypical populations. These discuss the behavioural, educational and neuropsychological characteristics of people with mathematical difficulties, and educational interventions to prevent, diagnose, treat or ameliorate such difficulties. The book brings together studies from different disciplines, including developmental psychology, neuroscience and education, and includes perspectives from practicing teachers.

"Learning Difficulties" draws on international research about learning difficulties to present a clear picture of the issues involved. It focuses on early identification, so that intervention can prevent or minimise the negative outcomes of persistent failure and explains how teachers can address problems effectively. Problems of socialisation and behaviour are discussed and brief coverage given to students' specific difficulties with reading and mathematics.

Literacy skills are fundamental to all areas of learning in the school curriculum but also have a profound impact on an individual's chances of finding satisfying work in the years beyond school. "Reading and Writing Difficulties" draws on the latest research from around the world to explain some of the causes of literacy problems and gives practical advice on methods to support students with their own difficulties.
