The purpose of the study was to evaluate the relation between Sluggish Cognitive Tempo (SCT) and academic functioning in a sample of 52 adolescents (40 males, 12 females) with Attention-Deficit/Hyperactivity Disorder (ADHD; M age?=?13.75). This study builds on prior work by utilizing an empirically-based and psychometrically validated measure of SCT, collecting ratings of SCT from both parents and teachers, and examining associations with multiple domains of academic functioning from both the parent and teacher perspective as well as grade point average (GPA). Both SCT and DSM-IV symptoms of inattention were significantly correlated with domains of academic functioning. Multiple regression analyses demonstrated that the parent-rated SCT Slow subscale predicted overall academic functioning, organizational skills impairment, and homework problems above and beyond ADHD symptoms and child and demographic characteristics known to be associated with academics, including intelligence, academic achievement, and family income. The teacher-rated SCT Low Initiation/Persistence subscale also predicted homework problems and was the only SCT variable to predict school grades above and beyond ADHD symptoms and relevant covariates. Both the SCT Slow and Low Initiation/Persistence subscales include items related to youth seeming apathetic, unmotivated, and lacking initiative, behaviors that are strongly related to ADHD symptoms of inattention but not currently captured by the DSM-IV. Implications of these findings towards supporting the external validity of the SCT construct are discussed along with potential implications for intervention.  相似文献

A surge of research has been conducted to examine memory editing mechanisms that help distinguish accurate from inaccurate memories. In the present experiment, the authors examined the ability of participants to use novelty detection, recollection rejection, and plausibility judgments to reject lures presented on a recognition memory test. Participants studied a list of word pairs that were arranged in a category relationship (both words from the same category) or an unrelated relationship (both words from different categories) under full or divided attention. At test, participants were given a yes/no recognition test in which they were to respond after seeing the test items for 400 ms or 2,800 ms. Some of the test items were rearranged word pairs that were consistent with the study relationship, whereas others were inconsistent with the study relationship. The results demonstrate that the participants required full attention at study to use novelty detection, recollection rejection, and plausibility judgments to reject lures. Moreover, the results indicate that a long response deadline at test was needed for participants to use both recollection rejection and plausibility judgments to reject lures.  相似文献

Past research has identified a number of asymmetries based on moral judgments. Beliefs about (a) what a person values, (b) whether a person is happy, (c) whether a person has shown weakness of will, and (d) whether a person deserves praise or blame seem to depend critically on whether participants themselves find the agent's behavior to be morally good or bad. To date, however, the origins of these asymmetries remain unknown. The present studies examine whether beliefs about an agent's “true self” explain these observed asymmetries based on moral judgment. Using the identical materials from previous studies in this area, a series of five experiments indicate that people show a general tendency to conclude that deep inside every individual there is a “true self” calling him or her to behave in ways that are morally virtuous. In turn, this belief causes people to hold different intuitions about what the agent values, whether the agent is happy, whether he or she has shown weakness of will, and whether he or she deserves praise or blame. These results not only help to answer important questions about how people attribute various mental states to others; they also contribute to important theoretical debates regarding how moral values may shape our beliefs about phenomena that, on the surface, appear to be decidedly non‐moral in nature.  相似文献

Prior studies have indicated that post-encoding stress can protect memories from the effects of forgetting, and this has been taken as evidence that stress facilitates memory consolidation. However, it is not known whether stress acts by directly influencing the strength of the underlying memories or whether it influences the generation process that plays a critical role in tests such as free recall. To address this issue, we examined the effects of stress produced by skydiving on recognition memory for negative and neutral pictures. Relative to a non-stress control condition, post-encoding stress in males was found to increase recognition memory for neutral pictures. However, stress was not found to improve recognition for emotional pictures, nor was it found to influence recognition memory in female participants. Additional analysis of recognition performance suggested that stress increased familiarity-based recognition rather than recollection. This study indicates that stress can improve familiarity-based recognition, thus showing that stress directly increases the strength of the underlying memories.  相似文献

Do philosophy professors specializing in ethics behave, on average, any morally better than do other professors? If not, do they at least behave more consistently with their expressed values? These questions have never been systematically studied. We examine the self-reported moral attitudes and moral behavior of 198 ethics professors, 208 non-ethicist philosophers, and 167 professors in departments other than philosophy on eight moral issues: academic society membership, voting, staying in touch with one's mother, vegetarianism, organ and blood donation, responsiveness to student emails, charitable giving, and honesty in responding to survey questionnaires. On some issues, we also had direct behavioral measures that we could compare with the self-reports. Ethicists expressed somewhat more stringent normative attitudes on some issues, such as vegetarianism and charitable donation. However, on no issue did ethicists show unequivocally better behavior than the two comparison groups. Our findings on attitude-behavior consistency were mixed: ethicists showed the strongest relationship between behavior and expressed moral attitude regarding voting but the weakest regarding charitable donation. We discuss implications for several models of the relationship between philosophical reflection and real-world moral behavior.  相似文献

A central feature of meaning in life is a consideration of more than oneself. We extend this logic to suggest that altruistically motivated prosociality – acting in ways that benefit others – is a self-transcending action that may provide meaning in life. Study 1 provided evidence of a relationship between self-reported prosocial behavior and meaning in life, even after statistically controlling for personality traits and self-esteem. Study 2 provided evidence that engaging in a prosocial action, via writing notes of gratitude, increased meaning in life. Study 3 provided evidence that individuals bolster perceptions of prosociality following threats to meaning. Study 4 suggested relationship satisfaction partially mediates the link between prosocial actions and meaning in life. These studies provide initial evidence that prosociality enhances meaning in life.  相似文献

Preeminent theories of attention-deficit/hyperactivity disorder (ADHD) suggest that motivation deficits are core underlying features of the disorder. However, it is currently unclear whether empirical evidence supports the assertion that significant group (ADHD v. comparison) differences in motivation exist or that problems with motivation contribute to the functional impairments that youth with ADHD experience. Accordingly, this review focused on evaluating and summarizing the empirical literature on the presence of motivation deficits and their association with functional outcomes in samples of youth with ADHD. Twenty studies met the review inclusion criteria. Results support the assertion that youth with ADHD have lower academic-related motivation in comparison to their peers and that motivation plays an important role in academic outcomes, with the strongest evidence to date for reading achievement. However, the available evidence is limited, and few existing studies are aligned with the much larger theoretical and empirical motivation literature in typically developing youth. Given preliminary evidence that motivation plays a role in the academic impairments of youth with ADHD, the review concludes with a discussion of whether current ADHD interventions adequately target motivation and highlights important future directions.  相似文献

Recent research suggests that emerging adulthood—the stage between adolescence and maturity marked by a lengthy process of identity development—constitutes a window of opportunity for museums to influence adults' lifelong science learning trajectories. The current study sought to explore the impact of a single museum visit on emerging adults' science self-efficacy, beliefs about their own abilities to learn or do science. A repeated measures design assessed the science self-efficacy of 244 emerging adults before, immediately after, and three months after a science museum visit. Results from surveys and interviews indicate that self-efficacy increased after the visit, but only females maintained their elevated self-efficacy three months after the visit. Increases were associated with the visit and with self-reports citing mastery at exhibits, vicariously watching others at exhibits, and positive emotional experiences within the museum. The article discusses the study's limitations as well as implications for research and museum practice.  相似文献

Honor crimes are violent acts that are experienced among different religions and ethnicities. This type of offense can be justified, either before or after the crime, by the offender’s perceived need to protect honor-based values. This study used Sykes and Matza’s neutralization theory to explain the offender’s justification of honor crimes. We used data from the United States Extremist Crime Database, which has incident, victim, and perpetrator level indicators for the population of honor crimes in the United States (N = 16). Using open source search files for the cases, neutralizations and justifications provided by the offenders are presented.  相似文献
