Recent research on children's thinking about the future has taken multiple directions, many of which are illustrated in the contributions to this special issue. In this commentary the topic is discussed in the context of research on children's understanding of time, and some of the adaptive challenges of thinking about the future are considered.…

This study explored age differences in preschoolers' temporal and social discounting and the association of these abilities. Research indicates that 4-year-olds are sensitive to rewards of differing magnitude (Lemmon & Moore, 2007). However, it is unclear whether preschoolers are able to consider length of time when making a choice to delay…

A group of 108 children from nursery school, first grade, and third grade were given five problems measuring the concept of time, in which they were required to judge and explain which of two partially overlapping events started first, which ended first, and which lasted for a longer time.

Investigates relations between time estimation ability and reaction time performance. Time estimation and forewarned reaction time tasks were used. Significant age and interval related differences were found. Findings were thought to be significant for developmental research and clinical assesment. (RH)

This study examines the development of children's understanding of temporal cycles and the relationship between cyclic concepts and cognitive development. A sample of 62 children, ranging in age from 4 to 10 years, were administered Piagetian tests of classification and seriation and a variety of specially designed cyclic tasks. (Author/JMB)

This paper reports two experimental studies of the development of time, speed and distance concepts in children. In Experiment I subjects (12 in each of four age groups: 5-, 8-, 11-year-olds, and adults) were asked to judge which of two electric trains on parallel tracks went faster, for the longer distance, or for more time. Subject's knowledge…

Delay of gratification and temporal span were investigated in 58 girls, ages 4 to 9 years, by estimated story durations, delay of gratification in a direct choice money test, and reproduction of a 60-second interval. (BD)

Developmental influences on temporal perspective is investigated. Objectives of the study were to clarify whether temporal perspective develops in a continuous or discontinuous fashion and to determine sex differences in relation to temporal perspective during adolescence. The study included 20 boys and 20 girls in each of four age groups: 9 &…

THE MAJOR FOCUS OF THIS STUDY WAS THE RELATIONSHIP BETWEEN CONSTRICTION OF TIME PERSPECTIVE AND PREFERENCES FOR CERTAIN TYPES OF SOLUTIONS TO PROBLEMS OF INTERNATIONAL, NATIONAL, AND LOCAL AFFAIRS. THREE GROUPS WERE FORMED ACCORDING TO AGE--UNDER 40, 40-59, AND 60 AND OVER. TABLES SHOW, IN PERCENTAGES, THE RESPONSES TO SUCH QUESTIONS AS WHAT THE…
