The goal of this study was to compare children's and adults eyewitness identification accuracy when presented with an array of possible suspects (‘lineup’) versus one suspect (‘showup’). Kindergarten children and adults were shown a slide show of a staged theft and subsequently asked whether, of the photo or photos shown them, the perpetrator was present or not. Children were more likely than adults to identify the perpetrator correctly when that suspect was present in the lineup or showup. Children were also more likely than adults to make an incorrect identification of another person when the perpetrator's photo was not present in the lineup or showup. Because false positive identification errors are more difficult to detect with the showup than the lineup, use of the showup may be less appropriate with child witnesses than with adults due to children's greater tendency to make positive identifications.

The study focused on the relationship of English proficiency and math performance in a sample of high school students, including 47% English language learners (ELLs). Data sources included state math test scores, study-specific pre- and posttest scores, problem solving in an online math tutorial, and responses to a self-report assessment of mathematics self-concept. English conversational and reading proficiency data were available for the ELLs. Results indicated that math performance for the ELLs increased with English-reading proficiency in a nonlinear manner. ELLs’ English-reading proficiency predicted math test scores, progress in the online math tutorial, and math self-concept.

Previous research has shown that kindergarten children often appear uncertain or confused when they try to execute inadequate instructions, but then go on to indicate that they had succeeded in doing what the instructor intended and that the instructions had been adequate for this purpose. The present study confirmed this finding and demonstrated that the children's positive evaluations of inade-'quate messages did not result from their forgetting their initial uncertainty. Extra emphasis on the ambiguous nature of the instructions helped the children realize that they might not have succeeded in doing what the instructor intended them to, but it did not help them realize that the instructions had been inadequate. In contrast, emphasizing exactly what they were to achieve in their instructionfollowing role did not help them recognize either their possible failure in the task or the inadequacy of the instructions. Their performance seems to result from a poor understanding of message quality and the role it plays in determining the success or failure of a communication.Recent studies have identified some interesting limitations in young children's comprehension-monitoring skills and knowledge about communication (

Children's ability to distinguish the literal meaning of a message and the speaker's communicative intent was investigated in 2 experiments. First- and second-grade children evaluated brief referential communication messages for ambiguity under 2 conditions. In an informed condition, the children knew which referent the speaker had intended. In an uninformed condition, they did not know the intended referent. 2 communication systems were used. In Experiment 1, the messages were written on cards and read to the child; in Experiment 2, a novel communication system was used. The developmental pattern of results was similar for both studies. The results showed that the first graders in the informed condition often claimed that an ambiguous message could not refer to a referent the speaker had not meant, whereas children in the uninformed condition were able to detect the referential ambiguity of the message. There were no condition differences for the second graders. The results suggest that young children's ability to analyze the literal meaning of a message is affected by the accessibility of the speaker's communicative intent and that children may develop a general ability to analyze representations of communicative intention.
