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

Pacific peoples represent one of the fastest growing population subgroups in New Zealand and suffer disproportionately from diabetes, obesity, and other diseases. There is little research on the predictors of behavioral problems in Pacific children or the role that cultural variables play in shaping the unique environments in which child development occurs This study aims to examine the: (1) prevalence of behavior problems at 2, 4, and 6 years-of-age among Pacific children, and (2) relationships between maternal, cultural, and socio-demographic factors and behavioral problems. Data were gathered from the Pacific Islands Families Study. Maternal reports of child behavior were obtained using the Child Behavior Checklist for over 1000 Pacific children. The prevalence of clinical internalizing problems at ages 2, 4, and 6 years was 16.8, 22 and 8.5%, and clinical externalizing was 6.7, 10.7, and 14.6% respectively. Significant risk factors associated with clinical internalizing were maternal depression, maternal smoking, intimate partner violence, and having a single mother. Significant risk factors for clinical externalizing were harsh parenting, maternal depression, having a New Zealand born mother, and low household income. Across dimensions, a protective factor was found for children with mothers who described themselves as strongly aligned with Pacific traditions. These findings contribute to the limited longitudinal data specific to children from different ethnic groups and demonstrate the importance of cultural factors in developmental outcomes. 相似文献

In English and other alphabetic systems read from left to right, the useful information acquired during each fixational pause is generally reported to extend 14–15 character spaces to the right of each fixation, but only 3–4 character spaces to the left, and certainly no farther than the beginning of the fixated word. However, this leftward extent is remarkably small and seems inconsistent with the general bilateral symmetry of vision. Accordingly, in the present study we investigated the influence of a fundamental component of text to the left of fixation—interword spaces—using a well-established eyetracking paradigm in which invisible boundaries were set up along individual sentence displays that were then read. Each boundary corresponded to the leftmost edge of a word in a sentence, so that as the eyes crossed a boundary, interword spaces in the text to the left of that word were obscured (by inserting a letter x). The proximity of the obscured text during each fixational pause was maintained at one, two, three, or four interword spaces from the left boundary of each fixated word. Normal fixations, regressions, and progressive saccades were disrupted when the obscured text was up to three interword spaces (an average of over 12 character spaces) away from the fixated word, while four interword spaces away produced no disruption. These findings suggest that influential information from text is acquired during each fixational pause from much farther leftward than is generally realized and that this information contributes to normal reading performance. Implications of these findings for reading are discussed. 相似文献

Elucidating the neural basis of joint attention in infancy promises to yield important insights into the development of language and social cognition, and directly informs developmental models of autism. We describe a new method for evaluating responding to joint attention performance in infancy that highlights the 9‐ to 10‐month period as a time interval of maximal individual differences. We then demonstrate that fractional anisotropy in the right uncinate fasciculus, a white matter fiber bundle connecting the amygdala to the ventral‐medial prefrontal cortex and anterior temporal pole, measured in 6‐month‐olds predicts individual differences in responding to joint attention at 9 months of age. The white matter microstructure of the right uncinate was not related to receptive language ability at 9 months. These findings suggest that the development of core nonverbal social communication skills in infancy is largely supported by preceding developments within right lateralized frontotemporal brain systems. 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
