The aim of this study is to fill a gap in intelligence research by presenting data for the average IQ in Morocco and for a comparable sample in Spain. Adult samples were administered the Raven Standard Progressive Matrices (SPM) (Raven, Court, & Raven, 2001) and scored for the total test and for the three sub-factors of gestalt continuation, verbal-analytical reasoning and visuospatial ability identified by Lynn, Allik, and Irwing (2004). The total test and the three factors have shown satisfactory reliability. Our results for the Moroccan sample show significant relationship between general intelligence factor, gestalt continuation and visuospatial ability with education level and income. Conversely, these variables have been shown to be independent for the Spanish sample. This sample obtained significantly higher scores for the four factors assessed than the Moroccan one. These differences have been found also comparing samples with the same education levels. Finally, the errors percentage for Moroccans has been higher than for Spaniards in all the items, suggesting that the level of difficulty was higher for the Moroccan sample.  相似文献

The purpose of this study was to assess whether understanding relational terminology (i.e., more, less, and fewer) mediates the effects of intervention on compare word problems. Second-grade classrooms (N=31) were randomly assigned to one of three conditions: researcher-designed word-problem intervention, researcher-designed calculation intervention, or business-as-usual (teacher-designed) control. Students in word-problem intervention classrooms received instruction on the compare problem type, which included a focus on understanding relational terminology within compare word problems. Analyses, which accounted for variance associated with classroom clustering, indicated that (a) compared with the calculation intervention and business-as-usual conditions, word-problem intervention significantly increased performance on all three subtypes of compare problems and on understanding relational terminology, and (b) the intervention effect was fully mediated by students' understanding of relational terminology for one subtype of compare problems and partially mediated by students' understanding of relational terminology for the other two subtypes.  相似文献

Using an experimental research design, 191 working adults were randomly assigned to two experimental conditions in order to test a theoretical model linking leader and follower positive psychological capital (PsyCap). Multiple methods were used to gather information from the participants. We found when leader PsyCap was manipulated experimentally, it was positively related to follower PsyCap. Subsequently, follower PsyCap was significantly related to employee's originality of ideas; one important component of creativity in the workplace. We discuss the theoretical contributions of linking leader and follower PsyCap in what emerges as a directional contagion effect, and the mediating role of follower PsyCap in enhancing follower creative task performance. Further, employee selection and development as well as leadership development practical implications are discussed. We conclude with a discussion of limitations and future research directions.  相似文献

Mexico has experienced dynamic changes in its religious landscape, but relatively little is known about the ways in which the affiliates of the diverse religious groups differ in their socioeconomic and family characteristics. This paper examines religious group differences in key demographic indicators of socioeconomic status and family structure using the 2000 Mexican Census. The changing patterns of religious affiliation in Mexico signal increasing religious, socioeconomic and familial diversity. Non-Christians and Mormons stand out for having higher scores on education and the wealth index relative to other religious groups. Most groups have lower rates of consensual unions and higher rates of marriage than do Catholics. These same groups also tend to have larger families and lower divorce/separation. These trends seem inconsistent with the Catholic teachings about marriage, divorce and contraception. Apparently, new groups are attracting adherents who have family orientations that differ from main-stream Mexican society.  相似文献

Using a speeded word fragment completion task, we assessed age differences in the automatic accessibility of emotional versus neutral words from semantic memory. Participants were instructed to complete a series of single-solution word fragments as quickly as possible. The results demonstrate that older adults are biased against accessing both positive and negative words relative to neutral words, whereas young adults are biased against accessing positive words only. These findings suggest an arousal-based accessibility bias favouring neutral stimuli in older adults coupled with a valence-based bias accessing negative and neutral stimuli for young adults.  相似文献

Power and organizational hierarchies are ubiquitous to social institutions that form the foundation of modern society. Power differentials may act to constrain or enhance people’s ability to make good ethical decisions. However, little scholarly work has examined perceptions of this important topic. The present effort seeks to address this issue by interviewing academics about hypothetical ethical problems that involve power differences among those involved. Academics discussed what they would do in these scenarios, often drawing on their own experiences. Using a think-aloud protocol, participants were prompted to discuss their reasoning and thinking behind their ethical decisions. These interview data were content analyzed using a semantic analysis program that identified a number of distinct ways that academics think about power differences and abuses in ethical situations. Implications of these findings are discussed.  相似文献

Studies on cognitive effects of positive emotions have associated positive emotions to broadened attention. Given the widely investigated relationship between self-focused attention and mood, it is important to investigate the effect of positive mood on visuospatial attention for self-related information. We used a performance-based measure to assess fluctuations in attentional broadening from self-related contrasted to not-self-related information. In Experiment 1, we checked that the self-related versus not-self-related stimuli did not evoke differential attention effects in general. In Experiment 2, we manipulated mood and found that an increase in positive mood was associated with a relative broadening of attention for self-related information. These results suggest that the meaning of the target of attention provides an interesting dimension for further investigation into the relation between positive emotions and attentional broadening.  相似文献

This study explored how four families who were in the midst of the process of a potential diagnosis of ‘Attention Deficit Hyperactivity Disorder’ (ADHD) for their child negotiated competing explanations of the problems. The research drew on a social constructionist, systemic and attachment lens to understand; (a) the constellations of meanings that are constructed by the families to explain the difficulties and (b) how families use strategies in their talk to account for or contest these constellations of meaning. A discursive analysis revealed that the families in this study, following initial explorations, adopted a sequential and cumulative dismissal of psychosocial explanations. Hence, the thrust of the conversation implicitly added up to the only possibility, the inevitable conclusion that it was ADHD. The malleability and flexibility in which the families explored these explanations varied and for some families the process of closure towards ‘illness’ as a dominant explanation sealed alternative conversations more than in others. The findings also revealed a complexity for the parents in balancing the need to offer discipline versus another response and this has clinical implications and highlights the need for further research in this area.  相似文献

Expertise in face recognition is characterized by high proficiency in distinguishing between individual faces. However, faces also enjoy an advantage at the early stage of basic-level detection, as demonstrated by efficient visual search for faces among nonface objects. In the present study, we asked (1) whether the face advantage in detection is a unique signature of face expertise, or whether it generalizes to other objects of expertise, and (2) whether expertise in face detection is intrinsically linked to expertise in face individuation. We compared how groups with varying degrees of object and face expertise (typical adults, developmental prosopagnosics [DP], and car experts) search for objects within and outside their domains of expertise (faces, cars, airplanes, and butterflies) among a variable set of object distractors. Across all three groups, search efficiency (indexed by reaction time slopes) was higher for faces and airplanes than for cars and butterflies. Notably, the search slope for car targets was considerably shallower in the car experts than in nonexperts. Although the mean face slope was slightly steeper among the DPs than in the other two groups, most of the DPs’ search slopes were well within the normative range. This pattern of results suggests that expertise in object detection is indeed associated with expertise at the subordinate level, that it is not specific to faces, and that the two types of expertise are distinct facilities. We discuss the potential role of experience in bridging between low-level discriminative features and high-level naturalistic categories.  相似文献
