Two studies are reported concerning performance differences and similarities across cultures. Pascual-Leone's tests of mental attention/energy (M-power) were administered to Zulu-speaking township children aged from 7 to 12 years. In study 1, the Compound Stimulus Visual Information task (CSVI) was used to determine whether children (N = 292) performed at theoretically predicted levels previously obtained with middle-class Canadian children. In study 2, the children (N = 252) were required to complete the Figural Intersection Test (FIT) four times. Unlike the CSVI, in which learning is controlled by training prior to testing, the FIT assumes basic familiarity with the general test requirements. The purpose of repeated testing was to assess the extent of learning across trials. The results for study 1 indicate that subjects do perform at the predicted levels on the CSVI and have the same M-power as Canadian children. The results for study 2 indicate that the subjects underperform on trial 1 of the FIT but overperform on trial 2 relative to Canadian children. Deux études sont rapportées concernant des différences et des similarités inter-culturelles de performance. Les tests de l'attention mentale/énergie (‘M-power’) de Pascual-Leone ont été administrés à des enfants âgés de 7 à 12 ans provenant de communautés d'expression Zulu. Dans la première étude, la tâche d'information visuelle du stimulus composé (CSVI) a été utilisée pour déterminer si les enfants (N = 292) pouvaient performer aux niveaux prédits théoriquement qui avaient été préalablement observés chez les enfants Canadiens de classe moyenne. Dans la seconde étude, les enfants (N = 252) devaient compléter quatre fois le test de l'intersection des figures (FIT). Contrairement au CSVI, dans lequel l'apprentissage est contrôlé par l'entraînement qui précède l'administration du test, le FIT assume une familiarité de base avec les prérequis généraux du test. Le but visé par la répétition du test était d'évaluer l'étendue de l'apprentissage en fonction des essais. Les résultats de la première étude indiquent que les sujets obtiennent les performances prévues au CSVI et possèdent le měme niveau de ‘M-Power’ que les enfants Canadiens. Les résultats de la seconde étude indiquent que, par comparaison avec les enfants Canadiens, les sujets livrent une performance inférieure au premier essai du FIT, alors qu'ils obtiennent une performance supérieure au second essai.  相似文献

This research explored the effect of teaching conditional discriminations with three procedures on the derivation of 36 stimuli relations (derived relations). The stimuli used consisted of three characteristics musical instruments, along with the corresponding picture. In the first experiment six university students were trained with simple stimuli and tested with compound auditory–visual samples; therefore, a one‐to‐many structure was used. In the second experiment, auditory stimuli were replaced by visual stimuli, for the samples used, for new students. A third experiment was implemented with an extra phase of training with compound stimuli for six new students. The structure of the experiments was: pretests (Xbcd–A; Xacd–B; Xabd–C; Xabc–D), training (A–B; A–C; A–D), and posttests (same as pretests). The difference between these conditions was the kind of stimuli used and a new phase of teaching used in condition 3: (Xbcd–A). The results indicate that training with simple stimuli on discriminations that include stimuli that are easy to discriminate from each other (words and sounds) is a sufficient condition for good posttest performance. However, when comparisons are made difficult (words only), participants show better performance on new tests if they have a learning history with compound stimuli.  相似文献

近似数量系统在个体数学能力的发展中起着重要的作用, 二者之间的关系受到年龄因素的影响。主要表现为, 随着年龄的增长, 相关程度逐渐减弱, 二者之间关系的作用机制可能由基数知识中介转变为多种中介变量的共同作用。未来可采用更严格的实验设计和多种研究方法考察各年龄段儿童近似数量系统与不同数学能力之间关系的发展趋势、因果方向、关键转折点和潜在机制, 以更好地理解近似数量系统在个体数学能力发展中所起的作用。  相似文献

轻度认知障碍(mild cognitive impairment, MCI)是介于正常认知老化和老年痴呆的中间状态, 目前尚无有效的药物治疗方案。重复经颅磁刺激(repetitive transcranial magnetic stimulation, rTMS)可通过诱导突触可塑性的改变来改善大脑的认知功能。对rTMS干预MCI认知功能的有效性及神经机制进行分析。未来研究应优化定位手段, 延长对干预效果的随访评估, 考察不同刺激参数和刺激靶区对干预有效性的影响, 以及结合脑成像技术来探索rTMS的干预机制。  相似文献

Background/Objective Brief transdiagnostic psychotherapies are a possible treatment for emotional disorders. We aimed to determine their efficacy on mild/moderate emotional disorders compared with treatment as usual (TAU) based on pharmacological interventions. Method: This study was a single-blinded randomized controlled trial with parallel design of three groups. Patients (N = 102) were assigned to brief individual psychotherapy (n = 34), brief group psychotherapy (n = 34) or TAU (n = 34). Participants were assessed before and after the interventions with the following measures: PHQ-15, PHQ-9, PHQ-PD, GAD-7, STAI, BDI-II, BSI-18, and SCID. We conducted per protocol and intention-to-treat analyses. Results: Brief psychotherapies were more effective than TAU for the reduction of emotional disorders symptoms and diagnoses with moderate/high effect sizes. TAU was only effective in reducing depressive symptoms. Conclusions: Brief transdiagnostic psychotherapies might be the treatment of choice for mild/moderate emotional disorders and they seem suitable to be implemented within health care systems.  相似文献

Background/Objective: Masturbation has historically been a sexual behaviour associated with negative connotations, as a consequence of traditional orthodox positions, despite its positive impact on health. The instruments developed to measure the attitude towards masturbation are scarce, and none of them have been validated in the Spanish adult population. This study aims to propose a short version of the Negative Attitudes Toward Masturbation Inventory (NATMI) and examine their psychometric properties (reliability and evidence of validity) in the Spanish adult population. Method: A total of 4,116 heterosexual adults aged 18-83 years (M = 40.58; SD = 12.24; 54.64% women) participated in the study. In addition to the NATMI, they answered other scales to assess sexual attitudes, sexual desire, propensity to become sexually excited/inhibited and sexual functioning. Results: Analysis of the construct validity of the NATMI resulted in a reduced version of ten items grouped into a single factor explaining 66% of the variance (ordinal alpha = .95). The evidence of validity is clear, as subjects with negative and positive attitude towards masturbation differed in religiousness, frequency of masturbation, erotophilia, positive attitude towards sexual fantasies, sexual inhibition and sexual functioning. Conclusions: The Spanish short version of NATMI provides reliable and valid measures in the Spanish adult population.  相似文献

Introduction: COVID-19 pandemic, declared on March 11, 2020, constitute an extraordinary health, social and economic global challenge. The impact on people's mental health is expected to be high. This paper sought to systematically review community-based studies on depression conducted during the COVID-19 and estimate the pooled prevalence of depression. Method: We searched for cross-sectional, community-based studies listed on PubMed or Web of Science from January 1, 2020 to May 8, 2020 that reported prevalence of depression. A random effect model was used to estimate the pooled proportion of depression. Results: A total of 12 studies were included in the meta-analysis, with prevalence rates of depression ranging from 7.45% to 48.30%. The pooled prevalence of depression was 25% (95% CI: 18% ? 33%), with significant heterogeneity between studies (I2 = 99.60%, p < .001). Conclusions: Compared with a global estimated prevalence of depression of 3.44% in 2017, our pooled prevalence of 25% appears to be 7 times higher, thus suggesting an important impact of the COVID-19 outbreak on people's mental health. Addressing mental health during and after this global health crisis should be placed into the international and national public health agenda to improve citizens’ wellbeing.  相似文献
