A retrospective longitudinal study of cognitive and language skills in poor reading comprehension 下载免费PDF全文

Fifty‐six specific poor reading comprehenders (SPRC) were selected in Grade 4 and retrospectively compared to good comprehenders at preschool (age 5) and at the end of kindergarten, Grade 1, and Grade 2. The results revealed deficits in vocabulary, grammar, verbal memory and early deficits in phonological awareness in most of the SPRC sample, beginning in preschool. The reading comprehension deficits in children with SPRC were not as marked in earlier assessments in Grade 1 and 2, probably because of the greater dependence on word decoding in reading comprehension in the early grades. 相似文献

We report two new phenomena of deontic reasoning: (1) For conditionals with deontic content such as, “If the nurse cleaned up the blood then she must have worn rubber gloves”, reasoners make more modus tollens inferences (from “she did not wear rubber gloves” to “she did not clean up the blood”) compared to conditionals with epistemic content. (2) For conditionals in the subjunctive mood with deontic content, such as, “If the nurse had cleaned up the blood then she must have had to wear rubber gloves”, reasoners make the same frequency of all inferences as they do for conditionals in the indicative mood with deontic content. In this regard, subjunctive deontics are different from subjunctive epistemic conditionals: reasoners interpret subjunctive epistemic conditionals as counterfactual and they make more negative inferences such as modus tollens from them. The experiments show these two phenomena occur for deontic conditionals that contain the modal auxiliary “must” and ones that do not. We discuss the results in terms of the mental representations of deontic conditionals and of counterfactual conditionals. 相似文献

We report two Experiments to compare counterfactual thoughts about how an outcome could have been different and causal explanations about why the outcome occurred. Experiment 1 showed that people generate counterfactual thoughts more often about controllable than uncontrollable events, whereas they generate causal explanations more often about unexpected than expected events. Counterfactual thoughts focus on specific factors, whereas causal explanations focus on both general and specific factors. Experiment 2 showed that in their spontaneous counterfactual thoughts, people focus on normal events just as often as exceptional events, unlike in directed counterfactual thoughts. The findings are consistent with the suggestion that counterfactual thoughts tend to focus on how a specific unwanted outcome could have been prevented, whereas causal explanations tend to provide more general causal information that enables future understanding, prediction, and intervention in a wide range of situations. 相似文献

We investigated whether narcissism affected dynamic decision-making performance in the presence and absence of misleading information. Performance was examined in a two-choice dynamic decision-making task where the optimal strategy was to forego an option providing larger immediate rewards in favor of an option that led to larger delayed rewards. Information regarding foregone rewards from the alternate option was presented or withheld to bias participants toward the sub-optimal choice. The results demonstrated that individuals high in narcissistic traits performed comparably to low narcissism individuals when foregone reward information was absent, but high narcissism individuals outperformed individuals low in narcissistic traits when misleading information was presented. The advantage for participants high in narcissistic traits was strongest within males, and, overall, males outperformed females when foregone rewards were present. While prior research emphasizes narcissists’ decision-making deficits, our findings provide evidence that individuals high in narcissistic traits excel at decision-making tasks that involve disregarding ambiguous information and focusing on the long-term utility of each option. Their superior ability at filtering out misleading information may reflect an effort to maintain their self-view or avoid ego threat. 相似文献

For more than 60 years it has been known that profiles from the Minnesota Multiphasic Personality Inventory (MMPI), obtained
from medical patients, are elevated when scores are plotted using general population norms. These elevations have been most
apparent on the neurotic triad (NTd), the first 3 clinical scales on the MMPI profile. More than 45 years have passed since
a nonreferred, normative sample of MMPIs was established from 50,000 consecutive medical outpatients. We present comparable
but contemporary normative data for the revised MMPI (MMPI-2) based on a nonreferred sample of 1,243 family medicine outpatients
(590 women; 653 men). As true for the original MMPI, contemporary medical outpatients have profiles that are significantly
different, clinically and statistically, from the general population norms for the MMPI-2. This is particularly evident in
elevations on the NTd. New normative tables of uniform medical T (UMT) scores were developed following the procedures used
to create the uniform T scores for the MMPI-2. Measures of internal consistency are reported; test-retest reliability was
established over a mean of 3.7 weeks, and results characterizing the stability of the validity and clinical scales are presented. 相似文献

Latent growth curve (LGC) modeling within the framework of structural equation modeling (SEM) is now highly regarded as one of the most powerful and informative approaches to the analysis of longitudinal data (see, e.g., Curran & Hussong, 2003). Whereas LGC modeling enables researchers to test for differences in developmental trajectories across time, conventional repeated measures analyses do not provide this opportunity. Nonetheless, a review of studies reported in most psychology journals reveals scant application of this methodological approach. One possible explanation for this limited use of LGC modeling is a lack of knowledge related to its application. The intent of this article, then, is to address this deficiency by presenting an annotated application of LGC modeling to health psychology data. Based on a sample of 405 Hong Kong Chinese women who recently underwent breast cancer surgery, we walk the readers through SEM modeling procedures that test for differences in both the initial status and rate of change in Psychological Morbidity and Social Adjustment at 1, 4, and 8 months postsurgery. We interpret findings from both a methodological and a substantive perspective. 相似文献

We report three experiments on semifactual conditionals such as 'even if he had worn his seatbelt he would have been injured'. Semifactuals contain a counterfactual antecedent (the presupposed fact is, he did not wear a seatbelt) and a true consequent (the fact is, he was injured). The experiments show that from the denial of the antecedent, 'he did not wear his seatbelt', reasoners do not infer the standard conclusion 'he was not injured' but instead they infer the asymmetric conclusion, 'he was injured'. From the affirmation of the consequent, 'he was injured', they do not infer the standard conclusion 'he wore his seatbelt' but instead they infer that there is no valid conclusion. The first experiment shows this pattern for 'even if' subjunctive conditionals compared to 'if' indicative conditionals, the second extends it to 'even if' subjunctive conditionals compared to 'even though' indicative concessives, and the third extends it to 'if...also/still' subjunctive conditionals. The results suggest that people think about two possibilities to understand a semifactual: the conjecture, he wore his seatbelt and he was injured, and the presupposed facts, he did not wear his seatbelt and he was injured. 相似文献

Antidepressants, in particular newer agents, are among the most widely prescribed medications worldwide with annual sales
of billions of dollars. The introduction of these agents in the market has passed through seemingly strict regulatory control.
Over a thousand randomized trials have been conducted with antidepressants. Statistically significant benefits have been repeatedly
demonstrated and the medical literature is flooded with several hundreds of "positive" trials (both pre-approval and post-approval).
However, two recent meta-analyses question this picture. The first meta-analysis used data that were submitted to FDA for
the approval of 12 antidepressant drugs. While only half of these trials had formally significant effectiveness, published
reports almost ubiquitously claimed significant results. "Negative" trials were either left unpublished or were distorted
to present "positive" results. The average benefit of these drugs based on the FDA data was of small magnitude, while the
published literature suggested larger benefits. A second meta-analysis using also FDA-submitted data examined the relationship
between treatment effect and baseline severity of depression. Drug-placebo differences increased with increasing baseline
severity and the difference became large enough to be clinically important only in the very small minority of patient populations
with severe major depression. In severe major depression, antidepressants did not become more effective, simply placebo lost
effectiveness. These data suggest that antidepressants may be less effective than their wide marketing suggests. Short-term
benefits are small and long-term balance of benefits and harms is understudied. I discuss how the use of many small randomized
trials with clinically non-relevant outcomes, improper interpretation of statistical significance, manipulated study design,
biased selection of study populations, short follow-up, and selective and distorted reporting of results has built and nourished
a seemingly evidence-based myth on antidepressant effectiveness and how higher evidence standards, with very large long-term
trials and careful prospective meta-analyses of individual-level data may reach closer to the truth and clinically useful
evidence. 相似文献
