Difficulties in understanding evolution are often rooted in early childhood, arising from naïve assumptions and cognitive biases. However, literature reviews mainly focus on school and university students' understanding of evolution, with only limited comprehensive reviews on children in early childhood aged up to 7 years. This systematic review…

Explored early-developing predictions of object motion through 6-month-old infants' head tracking and reaching for moving objects. Found evidence for infants' extrapolation of object motion on linear paths, in accord with principle of inertia. This tendency was remarkably resistant to counter-evidence, observed even after repeated presentations of…

Examined infants' use of configural and physical knowledge in segregating three-dimensional adjacent displays. Found that infants do use configural knowledge: they expect similar parts to belong to same unit and dissimilar parts to belong to distinct units. Also found that physical knowledge, such as impenetrability and support, influences their…

Investigates numerical competence in five-month-old infants using a violation-of-expectation paradigm. Supports previous findings that young children possess not only the competence for limited numerical abstraction, but also the ability to carry out addition and subtraction operations. An alternative explanation, that infants' responses are based…

Summarizes recent research which attempted to discover what children of different ages know about the appearance-reality distinction and related phenomena. Findings show that what helps children grasp the distinction is an increased cognizance of the fact that people are sentient subjects who have mental representations of objects and events. (PS)

Human infants are predisposed to organize their experience in terms of certain concepts (natural) and not others (unnatural). Three formal, necessary conditions on the naturalness of concepts are offered. The conditions attempt to link the problem of naturalness to principled distinctions between sense vs nonsense, simplicity vs complexity, and…

The concepts of front, back, and side may be easily understood in relation to an intrinsically fronted item, but with a nonfronted object they depend on situational or psychological cues. A study investigated a child's awareness of the front, back, and side of his own body and of fronted and nonfronted objects. Researchers hypothesized that a…

A social studies concept assessment instrument was developed and used to assess the concept development level of 24 kindergarten and 28 first grade subjects on n social concepts. Significant differences were found in scores for kindergarten and first grade; no significant differences were found in scores for race or sex. (Author/RM)

Participants aged 17-26, 39-51 and 59-76 solved concept problems to investigate intellectual correlates of concept identification as a function of stage of learning in adulthood. Differential ability-performance relations as a function of stage of learning were considerably less potent in the elderly v the young and middle aged. (Author)

This paper examines research studies that have concluded that elementary school children can learn more difficult and abstract social studies concepts than are taught in the traditional social studies curriculum. Research studies that focus on constraints on cognition, the use of embedded concepts, and understanding knowledge restructuring and…

Kindergarten, first and second grade children participated in a study of the development of conservation of equality and inequality. (BD)

Proposals for teaching concepts have been dominated by traditional paradigms. A review of research on concept structure and formation reveals evidence for alternative paradigms, e.g., exemplar, probabilistic, and schematic models. The research also indicates problems regarding the traditional models. Implications for relating alternative models to…

Five reader and nonreader male students (ages 6 to 10) were tested using the procedures developed by J. Downing and P. Oliver to investigate the development of the concept of the word. Results indicate significant effects for reading levels, age, stimuli, and a significant interaction between reading level and stimulus class. (Author/PN)

Discusses recent studies related to conceptual understanding in the domain of history, comparing the nature of understanding as found in history to that of other domains. Considers the role of sources in historical knowledge, the role of the historian, causation and explanation, and narrative exposition. (MJP)
