This study investigated developmental differences in story recall in children with attention-deficit/hyperactivity disorder
(ADHD), N = 57 (77.2% male) and their comparison peers, N = 98 (61.2% male). Children at the ages of 4–6 or 7–9 completed a free recall immediately after viewing each of two televised
stories, once in the presence of toys during viewing and once in their absence. This procedure was repeated with new stories
21 months later. Comparison children recalled more story events and showed a greater sensitivity to the thematic importance
of the story events than did children with ADHD, a pattern that remained stable over time. Older comparison children showed
a dramatic increase over time in the global coherence of their narrations, whereas the older children with ADHD showed limited
improvement over time. The implications of these findings for academic performance and the possible need for remediation are
discussed. 相似文献

Over the years, people have searched for deception cues in the liar's behavior. However, the sender's incentives to lie might be more revealing than behavior. In Experiment 1, an incentive was developed that was predictive of lying. Judges with access to incentive information in addition to behavior achieved almost perfect lie/truth detection. This was not a result of the speakers' behavior being transparent (Experiment 2) but because incentive information was useful to separate lies from truths (Experiments 2 and 3). Experiment 3 revealed that people may forego perfectly diagnostic contextual cues to base their judgments on illusory behavioral cues. 相似文献

Research examined construct meaning and validity for two new measures of receptive and expressive vocabulary for Spanish-speaking kindergarteners learning English. Substantive validity and generalizability of score meaning was assessed by examining correlations between an established measure (Peabody Picture Vocabulary Test–PPVT) and new measures (Stanford English Language Proficiency Test–SELP; Dynamic Indicators of Basic Early Literacy Skills, Word Use Fluency, DIBELS–WUF). Positive correlations between the SELP and PPVT supported validity of the SELP as a measure of receptive and expressive vocabulary for these children. DIBELS–WUF results were less clear with lower correlations between the PPVT raising questions about appropriateness. 相似文献

The learning abilities of planarian worms (Dugesia tigrina) were assessed by using a number of Pavlovian conditioning paradigms. Experiment 1 showed that planaria were susceptible to basic conditioning in that they readily developed a conditioned response to a change in ambient luminance when it was consistently paired with an electric shock over a number of trials. In Experiment 2, the change in luminance was presented in a compound with a vibration stimulus during conditioning. Subsequent tests revealed poor conditioning of the elements compared with control groups in which the animals were conditioned in the presence of the elements alone, an instance of overshadowing. In Experiment 3, pre-training of one of the elements before compound conditioning resulted in blocking of learning about the other element. These results add to other studies that have reported cue competition effects in animal species belonging to different phyla (chordate, mollusk, arthropod), suggesting that learning in these phyla could be ruled by similar principles. The results are discussed adopting an evolutionary-comparative approach. 相似文献

The present research investigated memory vulnerability to distortions. Different
encoding strategies were used when categorized lists were studied. The authors
assumed that an imagery strategy would be responsible for decreasing false
memories more than a word-whispering strategy, which is consistent with the
model of semantic access and previous research in the Deese-Roediger-McDermott
paradigm (the DRM paradigm; Deese, 1959;
Roediger & McDermott, 1995). A
normative study of category lists and 4 experiments were conducted to verify the
memory vulnerability to different encoding strategies (imagery, word-whispering,
control). Half of subjects recalled and half recognized previously studied
words. The results revealed a marked reduction in false recognition and recall
after imagery encoding, relative to after word-whispering encoding. 相似文献

Words whose spellings represent regular phonemic patterns, such asmint, show advantages in naming and lexical decision tasks over words, such aspint, that have exceptional relations between orthographic and phonemic patterns. We have extended such phenomena to the domain of lexical stress, by showing that disyllabic words whose spellings are consistent with their stress are easier to process than words whose spellings are misleading about stress. Such words are named more quickly and are pronounced with incorrect stress less often (Experiment 1). They are also classified more quickly and accurately in lexical decision tasks (Experiments 2 and 3). These results indicate that literate speakers have learned orthographic correlates to lexical stress in English. In addition, the similarities between results in the phonemic and prosodic domains indicate that models of reading developed for the former could be extended to the latter area. 相似文献

Junior kindergarten children, third-grade children, and college students were given a simultaneous pattern discrimination task, with simple and complex patterns, under either unlimited or limited (150 msec) viewing time. Under unlimited viewing, RTs to same patterns were faster than to different patterns for younger children and older males. Under limited viewing, same and different RTs were equivalent, but more errors were made in judging different patterns by all age groups. The RTs were longer to complex than to simple patterns, but the increase was differentially less for the youngest Ss, especially on same pairs. Since this age difference was found under both limited and unlimited viewing, it was not attributable to age differences in perceptual scanning strategies. The same-different asymmetry in RT under unlimited viewing and in error rate under limited viewing confirms across a wide age range previous findings with adults using codable stimuli. A two-process model for same and different judgments appears to be required, although young children may have had a response bias for same in Expt II. 相似文献
