This research developed a multimodal picture-word task for assessing the influence of visual speech on phonological processing by 100 children between 4 and 14 years of age. We assessed how manipulation of seemingly to-be-ignored auditory (A) and audiovisual (AV) phonological distractors affected picture naming without participants consciously…

Three experiments examined whether and how the strength of original information and strength of misleading information influenced 3- to 5-year olds' memory for an event. Findings indicated that children exposed to the event once reported more misled details than those seeing the event multiple times, and were just as susceptible to misleading…

Explored how 5.5- to 9-year-olds generalize to novel items a new phoneme spelling. Found they were more likely to use novel grapheme when the vowel appeared in the middle of a target; they were not more likely to use novel grapheme when it shared vowel and final consonant of the target than when it shared initial consonant and vowel.

Reports three experiments conducted to investigate factors controlling performance of nonreinforced verbal imitation. (WY)

Argues that dual-task performance is currently not interpretable because several compatible hypotheses have been offered to account for dual-task interference. Demonstrates inability to discriminate among alternative hypotheses by constructing a model which includes limited resources and response competition and requires running at least eight…

Three studies examined how reducing the executive function demands of a measure of strategic deception, the windows task, would affect 3-year-olds' performance. Findings demonstrated that providing an artificial response medium, even in the presence of an opponent, and having children play in partnership enabled them to adopt a successful…

Results obtained from adults and 8-, 10-, 12- and 14-year-olds indicate that children's advantage for repeated stimuli in reaction-time tasks and the decrease in magnitude of the repetition effect as age increases can be attributed to repetition of the same stimulus, rather than repetition of the same response. (MP)

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…

Examined the effects of drawing true and false reminders about a previously experienced magic show on 3- to 6-year-olds' suggestibility and source monitoring ability. Found that children who had drawn the reminders had better recall of reminders and better source memory than children who had only answered questions about them. Both groups reported…

Examined effects of age and degree of learning on children's susceptibility to retroactive interference. Found that children who participated repeatedly in target game recognized more information from that game than children who participated once. Both 4- and 7-year-olds were susceptible to retroactive interference; susceptibility was not affected…

Conducted with fourth, eighth, and twelfth graders, this study was designed to extend investigation of the contradictory training paradigm of the O'Brien and Overton study (1980) to include performances with conditional syllogisms and to bring this effect to bear on the controversies of false positive and negative assessments at different ages.…

Three studies investigated how experiencing nearby locations together in time influenced memory for location in 7-, 9-, and 11- year-olds and adults. Findings suggested that experiencing nearby locations together in time increased the weight children assigned to categorical information in their later estimates of location. Results were similar…

Examined how developmental differences in perceptual and conceptual priming between 8 and 19 years coincide with differences between familiarity and recollective responses on explicit memory tests employing the Remember/Know paradigm. Found few age-group differences in perceptual priming following a levels-of-processing encoding manipulation. In…

Investigated the role of an external clock in two temporal conditioning situations involving three-year olds. One situation required the spacing of responses to visual stimuli; the other, producing a response for a set duration. Found that the presence of the clock increased the efficiency of performance. (SW)

Two experiments investigated the contribution of automatic and intentional memory processes to 5- and 8-year-olds' acceptance of misinformation either read to them or self-generated from semantic and perceptual hints. Results from recognition tests conducted under two instructional conditions suggested that both automaticity and recollection…
