This paper proposes a new typology for understanding common research errors that expands on the four types of error commonly discussed in the research literature. Examples are presented to illustrate Type I and Type II errors, errors related to the interpretation of statistically significant and nonsignificant results respectively, with attention…

Three experiments are presented which examine the ability of 10-month-old infants to search in a new hiding place. (Author)

Reports that the New York "Times" and the Washington "Post" correct relatively few mistakes and that most corrections are of objective mistakes. (FL)

Results of analysis of 1,377 spelling error forms including three categories of spelling errors (consonantal, vowel, and sequential) demonstrate that majority of spelling errors are highly predictable when set of predefined rules based on phonological and sequential considerations are followed algorithmically. Eleven references and equivalent…

Reasons for college students making reversal errors translating a sentence to an equation were explored in six studies. The principal sources were haste, failure to check, failure to base the equation on the sentence meaning, and use of nonalgebraic symbols. Students could successfully check when prompted. (MNS)

In morphological processing in adult speech, irregular forms are subject to several types of errors, including overgeneralization and overtensing. A morphonaming task found that probability of these errors is affected by a phonological factor that derives from vowel phoneme frequencies in a complex fashion: whether the vowel in the past tense form…

Gender agreement elicitation was used with Russian children to examine how diminutives common in Russian child-directed speech affect gender learning. Children were shown pictures of familiar and novel animals and asked to describe them after hearing their names, which contained regular morphophonological cues to masculine or feminine gender.…

Three experiments examined limitations in 5-year-olds' understanding of mental and linguistic representations. Findings indicated relatively poor performance on task involving two labels for one object, requiring children to treat another's knowledge as representing only some feature of its real referent: dice but not eraser. There were parallel…

Investigates the differences in spelling error features among learning disabled and normal students across four grade levels of spelling achievement. Finds support for the theory of developmental word knowledge and for the position that learning disabled and normally achieving children acquire aspects of orthography in similar progressions. (RS)

Uses an error detection paradigm to examine the use of different standards of evaluation in younger and older adults who are skilled or less skilled at evaluating their understanding. Finds that skilled readers more often detect falsehoods and inconsistencies than nonsense words, whereas less skilled readers more often detect nonsense words and…

We report evidence for dissociation between explicit and implicit access to word representations in a deep dyslexic patient (JO). JO read aloud a series of ambiguous (e.g., bank) and unambiguous (e.g., food) words and performed a lexical decision task using these same items. When required to explicitly access the items (i.e., naming), JO showed…
