The authors present a multicomponent dynamic developmental theory of human autobiographical memory that emerges gradually across the preschool years. The components that contribute to the process of emergence include basic memory abilities, language and narrative, adult memory talk, temporal understanding, and understanding of self and others. The…

This article brings together two independent lines of research on numerally quantified expressions, e.g. two girls. One stems from work in linguistic theory and asks what truth conditional contributions such expressions make to the utterances in which they are used--in other words, what do numerals mean? The other comes from the study of language…

Switching between tasks produces decreases in performance as compared to repeating the same task. Asymmetrical switch costs occur when switching between two tasks of unequal difficulty. This asymmetry occurs because the cost is greater when switching to the less difficult task than when switching to the more difficult task. Various theories about…

The present study tests a model of category effects upon stimulus estimation in children. Prior work with adults suggests that people inductively generalize distributional information about a category of stimuli and use this information to adjust their estimates of individual stimuli in a way that maximizes average accuracy in estimation (see…

The ability to understand references to the absent enables conversation to move beyond the here-and-now to matters distant in both space and time. Such understanding requires appreciating the relation between language and communicative intent: one must recognize speakers' intentions to use language to converge on a shared conversational focus that…

This paper discusses the beginnings of post-natal psychic life, what constitutes the ordinary state of unintegration in the neonate, the nature of the baby's ego, and the clinical relevance of these questions. It is argued that an infant's state of passive unintegration in which the object functions as a "skin" to bind together the parts of the…

Background: It was proposed by Rogers & Pennington (1991) that an early deficit in imitation, together with a cascade of developmental disorders in emotion sharing and Theory of Mind, could be important in understanding autism. Having already found that imitation appeared not to be specifically or universally impaired in autism, the present study…

Elements and components of crisis situations are identified. Strategies and sequences of crisis intervention are described. Cultural implications of crisis intervention are discussed.

This paper presents the findings of a study exploring the self-regulated use of mathematical metalanguage in the early years. Young children were filmed on two occasions in the naturalistic context of their eight foundation stage settings, including both nursery and reception classes. The children were engaged in mathematical activities designed…

Aggressive behaviors in children and adolescents have undergone important conceptual and definitional modifications in the past two decades. In particular, subtypes of aggression have been proposed that separate the form and the function of the aggressive behaviors (i.e., social vs. physical aggression; reactive vs. proactive aggression).…

Most research into interactions between mothers and their infants with hearing impairments focuses on mothers' and infants' behaviors separately, speculating about the interplay among these behaviors and their effects on child development. In the present article, an intersubjective developmental theory focusing on the development of the…

Although there is a general agreement about the need for limits, structure, and guidance in a child's life, there is a strong difference of opinion among many professionals about the best ways to meet these needs. Some believe in more educational approaches, explaining to children the "why" of it, while others favor very firm disciplinary…

Mentoring develops resilience in youth. The author reflects on the power of mentoring, drawing on resilience science and school-based mentors in her own troubled young life.

The technological developments of the late 20th century opened up a whole vista of possibilities, both social and professional, that transformed millions of lives around the world. However, for the Millennial Generation, or people born in or after 1980, it also had a profound effect on shaping how they view and interact with their world: their…

Gilbert Gottlieb's formative role in establishing a science of experimental behavioral embryology is described. His experimental program on the development of species identification served as a model for developmental psychobiologists seeking alternatives to the nature-nurture dichotomies prevalent in the 20th century. Two of the major concepts…
