We consider human performance on an optimal stopping problem where people are presented with a list of numbers independently chosen from a uniform distribution. People are told how many numbers are in the list, and how they were chosen. People are then shown the numbers one at a time, and are instructed to choose the maximum, subject to the…

A core area of phonology is the study of phonotactics, or how sounds are linearly combined. Recent cross-linguistic analyses have shown that the phonology determines not only phonotactics but also the articulatory coordination or timing of adjacent sounds. In this article, I explore how the relation between coordination and phonotactics affects…

Lip movements were examined across several repetitive speaking conditions (speech alone and speaking concurrently with a linguistic, cognitive, or visuomotor challenge task) in 20 young adults. Performance in these nonspeech activities was also compared between isolated tasks and concurrent speech conditions. Linguistic challenges resulted in…

The experimental results of a collaborative problem solving and program development model that takes into consideration the cognitive and social activities that occur during software development is presented in this paper. This collaborative model is based on the Dual Common Model that focuses on individual cognitive aspects of problem solving and…

The treatment of body image has to be multifaceted and should be directed toward the treatment of the whole individual - body, mind, and spirit - with an ultimate culmination of acceptance and compassion for the self. This article presents information on a mindful approach to the treatment of body image as it pertains to concerns with body size…

Changes in 70 teachers' confidence, attitudes and science understanding were tested before and after a major in-service programme. Attitudes were assessed using a 49-item Likert-scale test that probed attitudes to practical science teaching and in-service training. Multi-choice and open-ended questions measured understanding of electricity;…

The purpose of this research was to discover whether the children (aged 9 to 11) were thinking while taking part in practical science activities. One method the author used was to video the activity and then watch the replay with each child in turn. She was then able to ask them what they had been thinking about at each stage. The majority of the…

Interest in U-shaped development has itself undergone a U-shaped progression. Twenty-five years ago, interest in U-shaped development was high. This interest was evident at a 1978 conference in Tel Aviv on "U-shaped Behavioral Growth" that resulted in the publication of a book of the same title 4 years later (Strauss, 1982). The breadth…

This article reviews didactical and psychologically based research on teachers' work and teacher thinking, narrative educational inquiry and studies of change in teachers' work and places them in the context of sociological theory about expert work and symbolic capital. The work of Abbott on the structure of expert work and knowledge, and Bourdieu…

Background: The Towers of London (TOL) and Hanoi (TOH) have been viewed as equivalent measures of planning and/or problem solving, although recent evidence in adults suggests that the underlying measurement characteristics of these two tasks may differ. As tower tasks are one of the few instruments that can be used to assess executive functioning…

There is considerable interest in the role of mental state language in theory of mind development. This study examines cognitive and desire state discourse of 43 mothers during play interactions with their two-year-old children and theory of mind as indicated by a battery of false belief tasks around the age of five. Desire state comments of…

We explore how the external social structure influences internal self-processes by examining whether one's status in the social structure influences one's ability to self-verify across multiple identities. We also examine whether greater verification is related to positive self-feelings (higher self-esteem and mastery) in a stable manner, across…

The number of children and adolescents accessing the Internet as well as the amount of time online are steadily increasing. The most common online activities include playing video games, accessing web sites, and communicating via chat rooms, email, and instant messaging. A theoretical framework for understanding the effects of Internet use on…

These are findings of theoretical interest from: (i) follow-up of a case study of a precocious reader; and (ii) normally developing readers who served as comparison groups. The precocious reader was first reported when 2-3 years of age (Cognition 74 (2000) 177). From 3 to 7 years of age her precocious reading development continued, her word…

Visual recognition memory is a robust form of memory that is evident from early infancy, shows pronounced developmental change, and is influenced by many of the same factors that affect adult memory; it is surprisingly resistant to decay and interference. Infant visual recognition memory shows (a) modest reliability, (b) good discriminant…
