Sixty children, aged 6 to 26 months, were observed discovering their mirror image and a reflected object. Compared to a control group's reactions, their behavior suggests that self-recognition in mirrors is independent of familiarity with reflecting surfaces and that ability to relate mirror space to real space is influenced by previous…

Proposes the hypothesis that preschoolers have number concepts based on the numbers 1-5 rather than on the decimal structure. Results suggest that children understand numbers to 5 as a privileged anchor. Proposes a new model for a representational system of numbers. (Author/DR)

Two experiments assessed the extent of newborns' ability to discriminate color. Results imply that newborns have some, albeit limited, capacity to discriminate chromatic from achromatic stimuli, and hence, are at least dichromats. (Author/DR)

Investigates relationships between syntactic awareness and reading proficiency. Fourth- and fifth-grade children of varying decoding ability differed in syntactic awareness according to their ability to correct grammatically deviant sentences in an oral language task. Significant correlations were observed between task results and measures of…

Investigates effects of perceptual salience and specific orientation values on 16 kindergarten and fourth-grade children executing a speeded sorting task. Kindergarten results supported the cognitive processing prediction that orientation sorting times would vary as a function of condition, but no differences were obtained for the fourth-grade…

Presents a cross-linguistic investigation of the development of adult language and cue comprehension strategies in native speakers of English and Dutch. Adult level performance was achieved much earlier by young English speakers, reflecting the different syntactic and semantic comprehension cues in these two languages. (Author/DR)

Presents five experiments that examine the ability of first graders, fourth graders, and adults to make causal inferences that explain how an unexpected and inconsistent "outcome" follows from an initial premise in a story. Results indicate that referential and causal coherence are empirically separable and should be distinguished theoretically.…

Compares typicality effects in recall between good and poor junior high readers to determine the influence of knowledge base upon memory. Results suggest that poor readers have a different knowledge base for familiar categories than good readers and that cognitive differences between them are related to differences in their semantic memories.…

Tested 32 4-year-olds and 32 6-year-olds for free and cued recall following either play-and-remember or sort-and-remember instructions and assessed them for their metamemory of the efficacy of conceptual and perceptual sorting strategies. Younger children recalled more items under sort-and-remember, whereas no recall differences were found for the…

Examines development of event memory by determining how personally experienced events with two types of structure were reported by kindergartners and adults. Events in making and playing with clay were organized causally and temporally. Results show that adults and children used a goal-based hierarchical structure to remember events, although use…

Because young children have poorer auditory temporal resolution than older children, a study measured the auditory filters of two 6-year-olds, two 10-year-olds, and two adults by having them detect a 400-ms sinusoid centered in a spectral notch in a band of noise. (HOD)

Investigates developmental changes in the accuracy of aimed movements made to an illuminated target lamp by children between the ages of 1.5 and 8 years. Shows accuracy decreased with decreasing availability of visual information and improved with age under all conditions. (HOD)

Investigates the extent to which learning disabled readers' atypical encoding relates to their deficiencies in semantic memory by comparing learning disabled and nondisabled readers in two age groups on dichotic listening tasks that included orienting and nonorienting instructions. (HOD)

Describes three experiments that examined the processing of speech by dyslexic readers. Compares their performance with that of age-matched and reading-ability-matched controls. Shows that dyslexics have difficulty with the nonlexical procedures involved in verbal repetition. (HOD)

Describes four experiments that examined the ability of second- and fifth-grade children and college adults to use "extra-list" cues to retrieve episodic information from memory. Shows that effective cue use varied with both the "match" of cue and event classification, and with the associative structure of permanent memory. (HOD)
