In their comment on D. Trafimow, M. D. Lee and E. Wagenmakers argued that the requisite probabilities to use in Bayes's theorem can always be found. In the present reply, the author asserts that M. D. Lee and E. Wagenmakers use a problematic assumption and that finding the requisite probabilities is not straightforward. After describing the…

A performance assessment consisting of 10 separate exercises was scored with a randomized scoring procedure. All responses to each exercise were rated once; in addition, a randomly selected subset of the responses to each exercise received an independent second rating. Each second rating was averaged with the corresponding first rating before the…

This article presents the findings of the first linguistic analysis of sign language interpreting carried out in Australia. A study was conducted on 10 Australian Sign Language/English interpreters to determine the rate and occurrence of interpreting omissions and the interpreters' level of metalinguistic awareness in relation to their production…

This paper investigates the processes that predict reading acquisition. Associations between (a) scaffolding errors (e.g., "torn" misread as "town" or "tarn"), other reading errors, and later reading and (b) vowel and rime inferences and later reading were explored. To assess both of these issues, 50 6-year-old children were shown a number of CVC…

The writing teacher's foremost job is leading students to see the valuable ideas they have to express. Writing is a way to share those ideas with the world rather than a way to be wrong, Anderson asserts. Teachers and parents too often focus on errors in student writing. This focus gives students the impression that writing well is about avoiding…

We explored how relational complexity and featural distraction, as varied in scene analogy problems, affect children's analogical reasoning performance. Results with 3- and 4-year-olds, 6- and 7-year-olds, 9- to 11-year-olds, and 13- and 14-year-olds indicate that when children can identify the critical structural relations in a scene analogy…

Many of the currently available statistical indexes to detect answer copying lack sufficient power at small [alpha] levels or when the amount of copying is relatively small. Furthermore, there is no one index that is uniformly best. Depending on the type or amount of copying, certain indexes are better than others. The purpose of this article was…

Errors involving universal quantification are common in contexts depicting sets of individuals in partial, one-to-one correspondence. In this article, we explore whether quantifier-spreading errors are more common with distributive quantifiers each and every than with all. In Experiments 1 and 2, 96 children (5- to 9-year-olds) viewed pairs of…

Morphological errors in reading aloud (e.g., "sexist" [right arrow] "sexy") are a central feature of the symptom-complex known as deep dyslexia, and have historically been viewed as evidence that representations at some level of the reading system are morphologically structured. However, it has been proposed (Funnell, 1987) that morphological…

Forty-eight college students, 24 of them dyslexic, were presented with four sentences of increasing complexity. Participants were asked to repeat each sentence and a record was kept of the number of repetitions required before 100% correct accuracy was achieved. None of the 24 control participants required a total of more than eight repetitions…

Do 9-month-old infants motorically simulate actions they perceive others perform? Two experiments tested whether action observation, like overt reaching, is sufficient to elicit the Piagetian A-not-B error. Infants recovered a toy hidden at location A or observed an experimenter recover the toy. After the toy was hidden at location B, infants in…

This study investigated the development of the understanding of class inclusion in children age 5, 7, and 9 years, whose performance on a qualitative class-inference task assessing their appreciation of the transitive and asymmetrical nature of inclusive relations within the animal domain was compared with their ability to make quantitative…

The hypothesis is introduced that 1 source of shift costs is the strengthening of task-related associations occurring whenever an overt response is produced. The authors tested this account by examining shift effects following errors and error compensation processes. The authors predicted that following a specific type of error, called task…

We compared the effects of guided lecture notes versus completed lecture notes on pre- to postlecture improvements in quiz performance across two sections of a college course. The results of a counterbalanced multielement design did not reveal consistent differences between the two note formats on students' mean quiz scores. However, fewer errors…

Previous research (e.g., Woodward & Baxter, 1997) found that Standards-based mathematics teaching provides marginal or no benefits for low achievers, in contrast with positive effects for middle and high ability students. A randomized quasi-experiment in 52 Canadian schools found that low achieving grade 7 and 8 students who received support…
