Two experiments examined developmental changes in accuracy of judgments about physical abilities in primary school children and college students. Subjects were asked to complete four physical tasks with and without benefit of practice. Found that children overestimated their physical abilities, individual differences in overestimation related to…

Contends that child and adolescent clinicians should consider the contributions of a constructivist developmental framework. Reviews a constructivist developmental model for counseling adolescents. Highlights developmental theory and therapy within the context of the mental health needs of adolescents experiencing aberrant behaviors and/or…

Attempts to determine whether children can use social-pragmatic cues to determine "what kind" of referent, object, or action an adult intends to indicate with a novel word. Doubts that children assume that a novel word refers to whatever nameless object is present. Suggests that lexical acquisition rests fundamentally on children's…

Examines whether knowledge of functional properties of a referent for a new name influences children's first guesses about whether that name refers to an object or a substance. Suggests that children do not rely on a single source of information, but rather draw on various kind of information, including perceptual characteristics of the entities…

Examined children's ability to accurately monitor sources of suggested information. Age differences were found in the degree to which a misleading suggestion led subjects to believe they actually remembered seeing events that had in fact only been suggested to them. Proposes that these age differences reflect developmental differences in the…

This research attempted to identify categories of cognitive development existing in creative writing samples (written by over 5000 gifted children ages 9-18) that provide a basis for developmental analysis. Four categories with three levels of development in each were identified: (1) self, (2) others, (3) problem solving, and (4) abstractness of…

This paper formulates guidelines for the design of children's play environments to optimize children's creativity during play. The paper defines "play," discusses Jean Piaget's work on cognitive adaptation, discusses creativity in the context of cognitive adaptation, and proposes designs for play environments to produce behavioral adaptation that…

This article discusses (1) assessment of discourse through listening and reading to evaluate comprehension problems; (2) developmental aspects of the relationship between listening and reading comprehension skills; (3) problems with selecting text passages and methods of testing comprehension; and (4) the development of a set of passages and a…

Provides the instructions to build a homemade calculator that can be used as a reinforcement device to assist primary students in memorizing their addition facts. (MDH)

This paper assesses the psychometric features of instruments used in assessing outcomes for survivors of traumatic brain injury, and describes a test development framework based on the principles of construct validity. This approach is seen to avoid common measurement difficulties. Emphasis is on cognitive and social dimensions of recovery.…

Younger preschoolers had significantly more difficulty than older ones in making an appearance-reality distinction between a person's apparent character, as indicated by his or her facial expression, and the person's real character, as evidenced by his or her behavior. (BB)

Rejects the neuronal fatigue, or selective adaptation, hypothesis of young infant habituation. Holds that studies cited by Dannemiller and Banks do not support the inferences of selective adaptation. Rejects the hypothetical neurophysiological mechanism of neuronal fatigue. Proposes that studies do not indicate that young infants' visual cortical…

A study documented 10 college students' understanding of the limit concept and the factors affecting changes in that understanding. Encouragement by the researchers for the students to change their common informal models of limit to more formal conceptions were met with extreme resistance. (Author/JJK)

Focuses on a single rule of grammar to produce evidence of a memory system for language acquisition and processing that is modular; independent of real-world meaning; unaffected by frequency and similarity; sensitive to formal distinctions; more sophisticated than the explicitly-taught rules it subsumes; developed independently of ambient input;…

Discusses the rationale and a method for the instructional use of graphing calculators as an intermediary step between the intuitive notion of the concept of a limit and its formal epsilon-delta definition. (JJK)
