Although individual differences in fluid reasoning reliably mediate predictions of attention-deficit/hyperactivity disorder (ADHD) symptoms from birth weight in youth with typical cognitive development (TD), it is unknown if this indirect effect operates similarly in the development of ADHD symptoms secondary to intellectual disability (ID). Thus, we evaluated mediation by fluid reasoning in a longitudinal sample of 163 youth (45% female) with (n = 52) or without (n = 111) ID who were followed prospectively from age 5 to age 13. At age 9, youth completed the Arithmetic subtest of the Wechsler Intelligence Scale for Children, a measure of fluid reasoning. At ages 9 and 13, mothers and teachers separately rated youth ADHD symptoms and mothers completed a diagnostic interview. Mediation was tested via path analysis with bootstrapped confidence intervals, and moderated mediation estimated whether indirect effects differed between ID and TD youth or based on youth IQ. Controlling for demographic factors and age 9 ADHD symptoms, age 9 Arithmetic mediated birth weight and multi-method/informant age 13 ADHD symptoms, such that birth weight positively predicted Arithmetic, which negatively predicted ADHD symptoms. Neither ID status nor IQ moderated the observed indirect effect through Arithmetic, suggesting that it was similar for ID and TD youth as well as across the range of youth IQs. These findings support previous evidence that fluid reasoning, as measured by Arithmetic, may causally mediate birth weight and ADHD symptoms, and suggest that this pathway operates similarly with respect to the development of ADHD symptoms in youth with ID. 相似文献

Although information about individuals' exposure to highly stressful events such as traumatic stressors is often very useful for clinicians and researchers, available measures are too long and complex for use in many settings. The Trauma History Screen (THS) was developed to provide a very brief and easy-to-complete self-report measure of exposure to high magnitude stressor (HMS) events and of events associated with significant and persisting posttraumatic distress (PPD). The measure assesses the frequency of HMS and PPD events, and it provides detailed information about PPD events. Test-retest reliability was studied in four samples, and temporal stability was good to excellent for items and trauma types and excellent for overall HMS and PPD scores. Comprehensibility of items was supported by expert ratings of how well items appeared to be understood by participants with relatively low reading levels. In five samples, construct validity was supported by findings of strong convergent validity with a longer measure of trauma exposure and by correlations of HMS and PPD scores with posttraumatic stress disorder (PTSD) symptoms. The psychometric properties of the THS appear to be comparable or better than longer and more complex measures of trauma exposure. 相似文献

This paper outlines the moral contours of human relationships with companion animals. The paper details three sources of duties
to and regarding companion animals: (1) from the animal’s status as property, (2) from the animal’s position in relationships
of care, love, and dependency, and (3) from the animal’s status as a sentient being with a good of its own. These three sources
of duties supplement one another and not only differentiate relationships with companion animals from wild animals and other
categories of domestic animals such as livestock, but they also overlap to provide moral agents with additional reasons for
preventing and avoiding harm to companion animals. The paper concludes that not only do owners and bystanders have direct
and indirect duties to protect companion animals from harm, but also that these duties have the potential, in some circumstances,
to clash with duties owed to the state and fellow citizens. 相似文献

The reminiscence bump is the tendency to recall relatively many personal events from the period in which the individual was between 10 and 30 years
old. This effect has only been found in autobiographical memory studies that used participants who were older than 40 years
of age. The increased recall of recent events possibly obscures the reminiscence bump in the results of younger participants.
In this study, a model was proposed that removes the increase for recent events from the temporal distribution. The model
basically estimates a retention function based on the 10 most recent years from the observed distributions and divides the
observed distributions by predictions derived from the estimated retention function. The model was examined with three simulated
data sets and one experimental data set. The results of the experiment offered two practical examples of how the model could
be used to investigate the temporal distribution of autobiographical memories. 相似文献

Despite extensive research, the role of phonological short-term memory (STM) during oral sentence comprehension remains unclear. We tested the hypothesis that phonological STM is involved in phonological analysis stages of the incoming words, but not in sentence comprehension per se. We compared phonological STM capacity and processing times for natural sentences and sentences containing phonetically ambiguous words. The sentences were presented for an auditory sentence anomaly judgement task and processing times for each word were measured. STM was measured via nonword and word immediate serial recall tasks, indexing phonological and lexicosemantic STM capacity, respectively. Significantly increased processing times were observed for phonetically ambiguous words, relative to natural stimuli in same sentence positions. Phonological STM capacity correlated with the size of this phonetic ambiguity effect. However, phonological STM capacity did not correlate with measures of later semantic integration processes while lexicosemantic STM did. This study suggests that phonological STM is associated with phonological analysis processes during sentence processing. 相似文献
