Normative values for word characteristics were obtained from a sample of 12 college-educated, totally congenitally blind subjects on the basis of their ratings of 161 nouns on scales of familiarity, concreteness, meaningfulness, and imageability. The dominant modality of imagery for each image-evoking word and the strongest word associate for each item also were recorded. The same data were collected for a group of sighted subjects, both to provide a comparison group for the blind subjects and to test the comparability of sighted subjects’ ratings with existing norms. Ratings for sighted subjects correlated strongly with those norms, although the coefficients were slightly higher for ratings of concreteness and imageability than for ratings of familiarity and meaningfulness. Ratings of blind subjects correlated only slightly lower with existing norms for imagery and concreteness, but considerably lower for familiarity and meaningfulness.  相似文献

Biological factors and psychometric intelligence: a review.   总被引:2,自引:0,他引:2  
Results from a synthesis of correlations between psychometric intelligence and two physical traits, head size and body size, are reported. Within-family studies are reviewed for evidence of pleiotropy, the effect of a single genetic factor on two traits. Studies are also reviewed to determine whether prenatal effects bias twin studies, leading to underestimates of genetic influence. An N-weighted mean partial correlation (controlling height) of .10 between intelligence and head size was found. Using a method developed by Van Valen (1974), the correlation of intelligence and brain size was estimated as .29 based on all the intelligence/head-size studies of adults and adolescents, and .44 based on studies measuring intelligence with IQ tests. The N-weighted mean partial correlations (controlling age) of intelligence and height were .18 for children and .22 for adults. The within-family studies indicated that pleiotropy may contribute to the correlation of intelligence with head size and to the correlation of intelligence with body size. Prenatal effects are not an important source of bias in twin studies or for heritability estimates based on them.  相似文献

Marriage is embedded in the web of spouses' broader social ties, and relationship quality with parents and parents-in-law is associated with marital quality. Guided by Family Systems theory and using three waves of dyadic data from 268 Chinese different-sex couples across the first several years of marriage, we first conducted a Random-Intercept Actor-Partner Interdependence Cross-lagged Panel Model (RI-APIM-CLPM) to examine the within-family longitudinal associations among husbands' and wives' relationship quality with parents, parents-in-law, and spouse. Then, husbands' and wives' filial obligations were added as predictors of between-family differences in their own and their partner's relationship quality in the three social ties. Among husbands, increased relationship quality in one social tie (e.g., with parents) predicted reductions in relationship quality in the other social ties (e.g., relationships with parents-in-law and marital quality). Our examination of between-family differences demonstrated that high levels of filial obligations predicted higher intergenerational relationship quality and marital quality. By simultaneously considering the within-family associations of multiple social ties and how filial obligations account for between-family differences in relationship quality, we contribute to a nuanced understanding of how Chinese couples' romantic partnerships are embedded in their broader family system.  相似文献

Research suggests a U.S. political ideology gap for taking COVID-19 precautions, but we do not know the role of cognitive risk (assessed here as perceived risk) and affective risk (assessed here as worry) in explaining why conservative Americans participated in fewer recommended precautions (e.g., mask wearing) and whether governmental trust attenuates the effect. We predicted that conservatives (compared with liberals) would take fewer precautions because they thought they were less at risk and were less worried about COVID-19, but that this would be more pronounced for those with low governmental trust. In this study, U.S. adults (representative sample: N = 738; Mage = 46.8; 52% women; 78% white) who had not had COVID-19 took two online surveys 2 weeks apart during the first wave of the pandemic (April 2020). Participants reported ideology, perceived risk of getting or dying of COVID-19, worry about COVID-19, and trust in the CDC and state officials at baseline. At follow-up, participants reported on COVID-19 precautions: (1) prevention behavior participation (e.g., mask wearing) and (2) behavioral willingness for future behaviors (e.g., vaccination). Results showed that, politically conservative Americans took fewer precautions due to lower worry (but unexpectedly not due to lower perceived risk). As predicted, when trust was high, the ideology gap was muted for predicting precautions as well as for predicting perceived risk and worry. In sum, conservatives worried less about COVID-19 which predicted fewer precautions, but trust in governmental institutions reduced this ideological gap. Improving governmental trust could be one fruitful path to increasing COVID-19 precautions.  相似文献

A substantial body of research indicates that higher education students from lower social class backgrounds tend to have poorer health than those from higher social class backgrounds. To investigate sleep as a potential mediator of this relationship, online survey responses of students from five large Australian universities, one Irish university and one large Australian technical college were analysed in three studies (Study 1 N = 628; Study 2 N = 376; Study 3 N = 446). The results revealed that sleep quality, sleep duration, sleep disturbances, pre-sleep worries and sleep schedule variability mediated the relationship between social class and physical and mental health. Sleep remained a significant mediator when controlling for related variables and other mediators. Thus, the findings suggest that sleep partly explains social class differences in health. We discuss the importance of addressing sleep issues among students from lower social class backgrounds.  相似文献

The nature and generality of the developmental association between phonological short‐term memory and vocabulary knowledge was explored in two studies. Study 1 investigated whether the link between vocabulary and verbal memory arises from the requirement to articulate memory items at recall or from earlier processes involved in the encoding and storage of the verbal material. Four‐year‐old children were tested on immediate memory measures which required either spoken recall (nonword repetition and digit span) or recognition of a sequence of nonwords. The phonological memory–vocabulary association was found to be as strong for the serial recognition as recall‐based measures, favouring the view that it is phonological short‐term memory capacity rather than speech output skills which constrain word learning. In Study 2, the association between phonological memory skills and vocabulary knowledge was found to be strong in teenaged as well as younger children, indicating that phonological memory constraints on word learning remain significant throughout childhood.

In these experiments a memory‐monitoring decision is made, whereby subjects must decide not only whether or not to‐be‐learned stimuli will be remembered—the focus of all of the past research into the Judgement of Learning (JOL)—but also whether they will be able to assess the source of those stimuli, as assessed by a new measure, Judgement of Source (JOS). In Experiment 1 subjects had to judge whether they would remember the occurrence and the source of items that were either seen or imagined. Although seen items were better remembered and sourced than imagined, subjects were unable to predict this outcome: they underestimated their ability to recall seen items and overestimated their ability to recall imagined items. In Experiment 2 subjects had to discriminate between self‐performed or other‐performed enacted or imagined events. We expected that the motor cues associated with overt performance should provide more sensory information than had the visual input in Experiment 1, and this should help subjects to discriminate between real and imagined items. As predicted, JOL magnitude showed that subjects were now able to predict accurately that they would recall more enacted events than imagined events. JOS magnitude showed that subjects incorrectly predicted that self‐enactment would assist source memory compared to imagination. However, it was the source of other‐focused events which was more accurately remembered. The results are discussed in terms of Koriat's (1997) view about cue utility in making JOLs.

According to Wollack and Schoenig (2018, The Sage encyclopedia of educational research, measurement, and evaluation. Thousand Oaks, CA: Sage, 260), benefiting from item preknowledge is one of the three broad types of test fraud that occur in educational assessments. We use tools from constrained statistical inference to suggest a new statistic that is based on item scores and response times and can be used to detect examinees who may have benefited from item preknowledge for the case when the set of compromised items is known. The asymptotic distribution of the new statistic under no preknowledge is proved to be a simple mixture of two χ2 distributions. We perform a detailed simulation study to show that the Type I error rate of the new statistic is very close to the nominal level and that the power of the new statistic is satisfactory in comparison to that of the existing statistics for detecting item preknowledge based on both item scores and response times. We also include a real data example to demonstrate the usefulness of the suggested statistic.  相似文献

Ethics has emerged as one of the most critical issues facing organizations. Given its importance, an extensive literature has evolved to understand the causes and consequences of (un)ethical decision making and behaviors in organizations. To date, much of this research has relied on research methods (e.g., experiments) that emphasize internal validity and control over external validity and generalizability. Although very informative, such studies frequently utilize samples that are not representative of working adults and their designs often fail to capture the contextual complexity that defines the day-to-day realities of organizational life. In this light, this special issue of Personnel Psychology encouraged scholars to investigate ethics within organizations and to offer rich theoretical explanations for why ethical failures and successes occur. The articles in this special issue address this important research agenda and make significant contributions to our understanding of ethics in organizations. Our introduction synthesizes these works, provides an overview of issues facing the broader behavioral ethics literature, and discusses areas for future research.  相似文献
