The present study examined the impact of working memory capacity (WMC) on college students' ability to solve probability problems while using a self‐explanation strategy. Participants learned to solve probability problems in one of three conditions: a backward‐faded self‐explanation condition, an example problem pairs self‐explanation condition, or a control (no self‐explanation) condition. Even when accounting for the impact of WMC, learning to problem‐solve using self‐explanation led to superior problem‐solving performance. Conditions that prompted self‐explanation during problem‐solving resulted in significantly better problem‐solving performance than the control condition. These findings provide insight into the influence of individual differences on problem‐solving when strategies are provided, as well as information about the effectiveness of the self‐explanation strategy during mathematical problem‐solving.

Many have argued that moral judgment is driven by one of two types of processes. Rationalists argue that reasoned processes are the source of moral judgments, whereas sentimentalists argue that emotional processes are. We provide evidence that both positions are mistaken; there are multiple mental processes involved in moral judgment, and it is possible to manipulate which process is engaged when considering moral dilemmas by presenting them in a non-native language. The Foreign-Language Effect (FLE) is the activation of systematic reasoning processes by thinking in a foreign language. We demonstrate that the FLE extends to moral judgment. This indicates that different types of processes can lead to the formation of differing moral judgments. One implication of the FLE is that it raises the possibility that moral judgments can be made more systematic, and that the type of processing used to form them might be relevant to normative and applied ethics.  相似文献

The purpose of the present study was to understand the reciprocal, bidirectional longitudinal relation between joint book reading and English receptive vocabulary. To address the research goals, a nationally representative sample of Head Start children, the Head Start Family and Child Experiences Survey (2003 cohort), was used for analysis. The children were aged 3–4 years at programme entry. The mothers' average age at programme entry was 39 years old. A parallel process model was utilized to examine the growth factors of joint book reading and receptive vocabulary in parallel. Three significant findings emerged: (1) initial levels of English receptive vocabulary and joint book reading positively covaried; (2) English receptive vocabulary and joint book reading were positively and reciprocally related to each other; and (3) slopes for joint book reading and English receptive vocabulary negatively covaried. Results suggest that joint book reading can support and scaffold Head Start children's English receptive vocabulary. Reciprocally, Head Start children's English receptive vocabulary appears to predict the extent to which they engage in joint book reading at home. Moreover, the frequency of joint book reading decreases as the children demonstrate higher levels of English receptive vocabulary. Copyright © 2015 John Wiley & Sons, Ltd.  相似文献

On the traditional view, moral distress arises only in cases where an individual believes she knows the morally right thing to do but fails to perform that action due to various constraints. We seek to motivate a broader understanding of moral distress. We begin by presenting six types of distress that fall outside the bounds of the traditional definition and explaining why they should be recognized as forms of moral distress. We then propose and defend a new and more expansive definition of moral distress and examine how it can enable the development of a taxonomy of moral distress.  相似文献

Although several different reading fluency intervention approaches appear promising for adolescents who are struggling readers, few studies have directly compared various approaches. The purpose of this study was twofold: 1) to determine the relative effects of word-oriented, fluency-oriented, comprehension-oriented, and multi-component interventions on the reading fluency performance of fifth and sixth grade struggling readers; and 2) to examine the concomitant effects of each intervention approach on comprehension. A within participant design, where all 29 participants received all interventions, was used. Outcomes were measured using instructional and transfer materials. The results provide support for a fluency-oriented and multi-component approach.  相似文献

Distress tolerance (DT), the perceived or actual ability to tolerate negative emotional or physical states, is inversely related to posttraumatic stress disorder (PTSD) symptoms in civilian, community samples. No studies to date have examined the relationship between DT and PTSD in clinical samples of veterans with a comorbid diagnosis of PTSD and a substance use disorder (SUD). Thus, the present study examined the relationship between DT and PTSD in a sample of predominately African American, male veterans (n = 75) diagnosed with comorbid PTSD and SUD (according to a structured clinical interview). Results of hierarchical linear regression models indicated that DT was inversely related to total PTSD symptom severity score, above and beyond depressive symptoms and SUD severity. Of the 4 symptom clusters, DT was inversely associated with intrusions and hyperarousal. These findings are discussed in light of previous work with civilian samples. Determining whether treatment incorporating DT skills would be useful for veterans undergoing PTSD treatment should be evaluated.  相似文献

Cultural learning is an adaptive mechanism which can lead to changes in behavior and cognition much faster than naturally selected genetic change. Although social learning is prevalent in many species, the capacity for significant cumulative culture remains restricted to humans. This capacity has been a driving force behind the evolution of complexity in our technologies and societies, and has allowed us to become the most widespread mammal on earth. The comparative study of cultural cognition assesses where important differences lie between species. A combination of observational studies in the wild, experimental studies in captivity, and field experiments together provide the most comprehensive methods with which to tackle the question.

Mentally placing the self in the physical position of another person might engage social perspective taking because participants have to match their own position with that of another. We investigated the influence of personal (sex), interpersonal (siblings, parental marital status), and cultural (individualistic, collectivistic) factors on individuals' abilities to mentally take the position of front‐facing and back‐facing figures in an online study (369 participants). Replicating findings from laboratory studies responses were slower for front‐facing than back‐facing figures. Having siblings, parents' marital status, and cultural background influenced task performance in theoretically predictable ways. The present perspective‐taking task is a promising experimental paradigm to assess social perspective taking and one that is free from the response biases inherent in self‐report.  相似文献

The authors studied the development of postural adjustments associated with the initiation of gait in children by using kinematic and electromyographic (EMG) analysis. Participants (N = 28) included infants with 1-4 and 9-17 months of walking experience, children 4-5 years of age, and adults. Anticipatory postural adjustments (APA) were present in the youngest age groups, including a clear anticipatory lateral tilt of the pelvis and the stance leg, which enabled the child to unload the opposite leg shortly before its swing phase. An anticipatory activation of the hip abductor of the leg in stance phase prior to heel-off was found, suggesting pelvis stabilization. APA did not appear consistently until 4-5 years of age. A decrease in segmental oscillations occurred across the ages, indicating better control of intersegmental coordination in the frontal and sagittal planes during the postural phase of gait initiation. Young walkers presented APA involving movements of both the upper and the lower parts of the body, whereas, like adults, 4- to 5-year-olds were able to laterally shift only the pelvis and the stance leg. The oldest children and the adults also showed lower activation levels of hip and knee muscles but higher activation at the ankle level. Those kinematic and EMG results taken together suggest a clear developmental sequence from an en bloc operation of the body through an articulated operation with maturation, walking experience, or both.  相似文献

A highly cited article by Vohs, Mead, and Goode (2006) reported several experiments in which an incidental reminder of money produced large effects on subsequent behaviors unrelated to money. We attempted 2 high-powered direct replications of the first experiment, which found that money-primed subjects worked on a puzzle nearly twice as long as controls before quitting. The replication studies showed no evidence of money priming. Moreover, 25% of the subjects in our studies solved the puzzle correctly or incorrectly, whereas none reportedly did so in the original study. We also list anomalies in the reported results of the original study.  相似文献
