Abstract The goal of this study was to investigate if the selection of external information for storage in visual working memory requires control by the central executive when the categorization of targets is guided by instructions. The design was experimental 3 (concurrent task) x 2 (instruction). Forty-eight university students saw eight colored shapes, four of them surrounded by square outlines. Memory was assessed using a recognition task. Targets varied with instructions: targets were presented within squares in the first block and outside squares in the second block. There were three concurrent tasks: no task, articulatory suppression, and backward counting. Performance was measured by hits, false alarms, corrected recognition, and sensitivity (A’), compared using within-subject ANOVAs. Results showed a main effect only for concurrent task, with lower performance in the backward counting condition for all measures. These results suggest that the central executive does not control the perceptual filter, corroborating earlier results.
摘要本研究的目的是探讨在指令引导下对目标进行分类时,视觉工作记忆中外部信息的选择是否需要中央执行控制。设计为实验3(并发任务)x 2(指令)。48名大学生看到了8个彩色的形状,其中4个被方形轮廓包围。记忆力通过识别任务进行评估。目标随着指令的不同而变化:目标在第一个区域被呈现在方块内,在第二个区域被呈现在方块外。有三个并发任务:无任务、发音抑制和反向计数。性能通过命中、误报、纠正识别和灵敏度(A ')来衡量,并使用受试者内方差分析进行比较。结果表明,仅对并发任务有主要影响,在所有测量条件下,反向计数条件的性能都较低。这些结果表明,中央执行器并不控制感知过滤器,证实了之前的结果。

Resumo Trata-se de um estudo brasileiro, transversal, mediado pela Internet com o objetivo de descrever como diferenças temperamentais associam-se ao uso de oito práticas de medicina alternativa e complementar (MAC): ioga, meditação, reiki, acupuntura, massagem, tai chi chuan, homeopatia e floral. A amostra foi composta por 22.415 indivíduos, sendo 69,5% mulheres, com idade média de 28,8 anos (DP = 9,1). As práticas mais utilizadas foram massagem e ioga e as variáveis sexo, idade, renda e diagnóstico psicopatológico ao longo da vida associaram-se a todas as práticas, exceto com tai chi chuan. Análise inferencial se baseou em modelo de regressão logística e os resultados foram calculados com base na razão de chances com intervalo de confiança de 95%. Observou-se que manifestações adaptativas de traços e de tipos psicológicos, associaram-se a maiores chances de praticar MAC. Resultados sugerem que perfis com maior regulação emocional tendem a utilizar mais frequentemente MAC e, possivelmente, obter benefícios.
这是一项巴西横断面研究,通过互联网进行,目的是描述情绪差异如何与八种替代和补充医学实践(MAC)的使用相关:瑜伽、冥想、灵气、针灸、按摩、太极拳、顺势疗法和花卉。样本包括22.415名受试者,其中69.5%为女性,平均年龄28.8岁(sd = 9.1)。最常用的练习是按摩和瑜伽,性别、年龄、收入和终身精神病理诊断变量与所有练习相关,除了太极拳。推理分析基于logistic回归模型,结果基于概率比计算,置信区间为95%。我们观察到,心理特征和类型的适应性表现与更高的练习MAC的机会有关。结果表明,情绪调节较高的人倾向于更频繁地使用MAC,并可能获得好处。

Abstract Self-monitoring regulates the expression of behavior, which can facilitate relationships in different contexts. The aim of this study was to confirm the factorial structure of the exploratory analysis of the Self-monitoring Scale (SMS) and investigate the effect of the independent variable Self-monitoring on the dependent variable Social Problem Solving. Participants were 400 university students of different degrees, both sexes, aged between 18 and 58 years (M=31.3 and SD=9.4) and with data collected on the spot. Confirmatory Factor Analysis found fit indexes that support the two-factor model, corroborated by the literature. The regression analysis demonstrated that Self-monitoring predicted the Resolution of Social Problems regarding the Problem Orientation (PO) factor, suggesting that students with a higher PO would be less aware of the context to regulate behavior. The study showed the functioning of the instruments that measure concepts that are still little explored in Higher Education studies.
自我监控调节行为的表达,可以促进不同情境下的人际关系。本研究旨在确认自我监控量表(SMS)探索性分析的因子结构,并探讨自变量自我监控对因变量社会问题解决的影响。参与者是400名不同学位的大学生,男女皆有,年龄在18到58岁之间(M=31.3, SD=9.4),数据收集于现场。验证性因子分析发现,拟合指标支持双因素模型,证实了文献。回归分析表明,自我监控在问题取向(Problem Orientation, PO)因子上对社会问题的解决具有预测作用,说明问题取向高的学生对环境的认知能力较弱。这项研究显示了测量概念的工具的功能,这些概念在高等教育研究中仍然很少被探索。

Resumo Objetivou-se investigar as crenças de professores acerca da violência sexual contra crianças e adolescentes. Uma amostra de 164 professores de ensino fundamental e médio, de escolas públicas e privadas, respondeu a um questionário sociodemográfico e a Escala de Crenças sobre Abuso Sexual (ECAS). Análises descritivas, de frequência, testes U de Mann-Whitney e teste de Kruskall-Wallis foram realizados. O escore médio da ECAS, nessa amostra, foi de 25,74 (DP = 6,83), indicando uma tendência à discordância e neutralidade à tolerância/legitimação. Ao se comparar grupos, as variáveis gênero, faixa etária e presença de filhos mostraram ter influência sob as crenças. A experiência com casos de suspeita, participação em cursos ou palestras e conhecimento do Estatuto da Criança e do Adolescente não apresentaram diferenças estatisticamente significativas em relação às crenças. Tais resultados foram discutidos a partir de considerações sobre gênero, sexualidade, capacitação profissional e características de crenças. É necessário investimento em estratégias de formação continuada, sendo que devem ser sensíveis às características dos participantes e às suas crenças.
摘要本研究旨在探讨教师对儿童青少年性暴力的看法。164名公立和私立学校的小学和中学教师回答了一份社会人口学问卷和性虐待信念量表(ECAS)。进行描述性分析、频率分析、Mann-Whitney U检验和kruskal -Wallis检验。该样本的平均ECAS评分为25.74 (sd = 6.83),表明有不一致的倾向和容忍/合法化的中立。在比较群体时,性别、年龄和孩子的存在对信念有影响。疑似案件的经验、参加课程或讲座的经验以及对儿童和青少年地位的了解在信仰方面没有统计学上的显著差异。这些结果从性别、性、职业培训和信仰特征等方面进行了讨论。需要对继续教育战略进行投资,这些战略必须对参与者的特点和他们的信仰敏感。

Resumo Este estudo teve como objetivo propor um modelo explicativo de não adesão ao paradigma psicossocial da saúde mental a partir dos estereótipos, das crenças sobre a etiologia da doença mental, da percepção de ameaça e do preconceito. Para tanto, contou-se com a participação de 400 universitários, com média de idade de 24,64 anos (DP = 6, 64), sendo a maioria do sexo feminino (75,6%). Para a proposição do modelo, foi realizada uma path analysis. O modelo proposto demonstrou que quanto maior a percepção de ameaça e a concordância com o estereótipo de incapacidade, menor o apoio ao paradigma psicossocial. Ademais, verificou-se que as crenças acerca da etiologia da doença mental e os estereótipos estão na base da percepção de ameaça e todas essas variáveis juntas predizem maior preconceito. Os achados desta pesquisa fornecem subsídios científicos para a realização de intervenções eficazes e consistentes que fortaleçam o paradigma psicossocial no cenário nacional.
摘要本研究旨在从对精神疾病病因的刻板印象、对威胁和偏见的感知等方面,提出一种不坚持心理社会心理健康范式的解释模型。为此,我们统计了400名大学生的参与,平均年龄24.64岁(sd = 6.64),其中大多数是女性(75.6%)。为了提出模型,进行了路径分析。提出的模型表明,威胁感知和残疾刻板印象的一致性越高,对社会心理范式的支持就越低。此外,对精神疾病病因学的信念和刻板印象是威胁感知的基础,所有这些变量共同预测更大的偏见。这项研究的结果为实施有效和一致的干预措施提供了科学支持,以加强国家情景下的社会心理范式。

Abstract Cognitive deficits are common among post-stroke patients. Cognitive impairments of this sort are mediated by age and education. In Brazil, the only specific cognitive screening tool designed for post-stroke patients is the Cognitive Screening Test (Triagem Cognitiva - TRIACOG). The goal of this study was to investigate validity evidence related to external variables for the TRIACOG. Our sample included 153 adults and elderly people (M = 60.08, SD = 9.61) from Porto Alegre and metropolitan area, comprising 87 post-stroke patients and 66 healthy individuals. Three-way ANOVAs were used to assess main effects and interactions between the variables group (clinical/control), age and education. An influence of group and age on scores in the TRIACOG was found. We emphasize the relevance of these results to the selection of cut-off points for the tasks and cognitive functions assessed by the instrument, considering education and age, so as to allow more accurate identification of deficits in post-stroke patients.
脑卒中后患者普遍存在认知障碍。这类认知障碍受年龄和教育程度的影响。在巴西,唯一专门为脑卒中后患者设计的认知筛查工具是认知筛查测试(Triagem Cognitiva - TRIACOG)。本研究的目的是调查与TRIACOG外部变量相关的效度证据。我们的样本包括来自阿雷格里港和大都市地区的153名成人和老年人(M = 60.08, SD = 9.61),其中卒中后患者87名,健康人66名。采用三向方差分析(Three-way anova)评估各组(临床/对照)、年龄和教育程度之间的主要效应和相互作用。实验组和年龄对TRIACOG评分有影响。我们强调这些结果与仪器评估任务和认知功能的分界点选择的相关性,考虑教育程度和年龄,以便更准确地识别卒中后患者的缺陷。

Abstract The present study aimed to develop and validate the Scale of Attitudes towards Lynching (Escala de Atitudes frente ao Linchamento - EAL). For this purpose, 2 studies were conducted. Study 1 aimed to test the measure’s structure-based validity and internal consistency and included 428 undergraduate and graduate students from the 5 Brazilian regions, with a mean age of 26.86 (SD =7.92). The results of the first study showed adequate psychometric indexes, indicating the bifactorial structure of the construct: crimes against property (α = 0.97) and heinous crimes (α = 0.97). Study 2 aimed to test the replicability of the bifactorial structure obtained in study 1 and included 481 college students from all Brazilian regions with an average age of 27.47 (SD = 9.23). The results supported the adequacy of the bifactorial solution (GFI = 92, CFI = 97, TLI = 97, RMSEA = 0.08). Overall, the EAL presented satisfactory psychometric characteristics that can support future studies.
摘要本研究旨在编制并验证私刑态度量表(Escala de Atitudes frente ao Linchamento - EAL)。为此,我们进行了2项研究。研究1旨在检验该量表的结构效度和内部一致性,研究对象为来自巴西5个地区的428名本科生和研究生,平均年龄26.86岁(SD =7.92)。第一项研究结果显示心理测量指标充足,表明该建构具有双因子结构:财产犯罪(α = 0.97)和十恶不赦的犯罪(α = 0.97)。研究2旨在检验研究1中获得的双因子结构的可重复性,研究纳入了来自巴西各地区的481名大学生,平均年龄为27.47岁(SD = 9.23)。结果支持双因子解决方案的充分性(GFI = 92, CFI = 97, TLI = 97, RMSEA = 0.08)。总体而言,EAL表现出令人满意的心理测量特征,可以支持未来的研究。

Abstract We evaluated the effect of prematurity and the infant’s temperament on the mother-infant behaviors in the Face-to-Face Still-Face Paradigm (FFSF). The study included 75 mothers and their infants (37 preterm and 38 term) between three and four months of age (corrected age for preterm infants). The mothers responded to a perception scale of the infants’ temperament and the dyads were observed in a structured condition (FFSF). The FFSF Paradigm, divided into three episodes, made it possible to analyze the behaviors of: Positive Social Orientation, Negative Social Orientation and Self-comfort. The averages recorded for these categories were analyzed in a Multivariate ANOVA (factors: prematurity and temperament). Temperament had more effect on maternal and infant behaviors, suggesting that this factor may influence mother-infant interaction. The results can guide possible interventions with families.
摘要本研究探讨了在“面对面-静止-面对”范式(FFSF)中,早产儿和婴儿气质对母婴行为的影响。这项研究包括75名母亲和她们的婴儿(37名早产儿和38名足月婴儿),年龄在3到4个月之间(早产儿的校正年龄)。母亲对婴儿气质的感知量表做出反应,二人组在结构化条件(FFSF)中观察。FFSF范式分为三集,可以分析积极社会取向、消极社会取向和自我安慰的行为。这些类别记录的平均值用多变量方差分析(因素:早产和气质)进行分析。气质对母亲和婴儿行为的影响更大,表明这一因素可能影响母婴互动。结果可以指导可能的家庭干预措施。

Resumo Esta pesquisa objetivou adaptar e validar para o contexto brasileiro a Suicide Helpfulness Scale - SHS (Escala de Apoio à pessoa em Risco de Suicídio - EARS), por meio de dois estudos. Do Estudo 1, participaram 206 estudantes, com idade média de 16,73 anos. Estes responderam à EARS e a questões sociodemográficas. Os resultados obtidos apoiaram o modelo original de quatro fatores e verificou-se um alfa de Cronbach de 0,86 e Confiabilidade Composta de 0,90. Do Estudo 2, de caráter confirmatório, participaram 212 estudantes, predominantemente do sexo feminino (58%) e com idade média de 16,67 anos. Foram testados três modelos e os resultados corroboraram a adequação da estrutura tetrafatorial, observando-se indicadores de ajuste meritórios. Assim, conclui-se que a EARS apresenta características psicométricas adequadas para o contexto brasileiro e pode ser utilizada em pesquisas que investiguem o quanto os jovens estão dispostos a ajudar uma pessoa em risco de suicídio.
摘要本研究旨在通过两项研究,对巴西的自杀帮助量表(SHS)进行调整和验证。在研究1中,206名学生参与,平均年龄16.73岁。他们回答了耳朵和社会人口学问题。结果支持原四因素模型,Cronbach alpha为0.86,复合信度为0.90。在验证性研究2中,212名学生参与,主要是女性(58%),平均年龄16.67岁。对三个模型进行了测试,结果证实了四元结构的充分性,观察到有价值的调整指标。因此,我们得出结论,耳朵具有适合巴西环境的心理测量特征,并可用于调查年轻人愿意帮助有自杀风险的人的程度的研究。

Abstract This study aimed to adapt the Motivation to Cheat Scale (MCS) to the Brazilian student context, gathering evidence of validity based on its internal structure. Two studies were carried out. In Study 1, the 20 items of the MCS were translated into Portuguese and evaluated semantically by ten students, who consider them sufficiently understandable. Subsequently, seeking to know the internal structure of the measure, there was the participation of 212 high school students (M = 16.10 years; SD = 1.02). An exploratory factor analysis indicated the existence of two factors (search for success and moral initiation), which were saturated 18 items. O Study 2 aimed to verify this factorial structure. Logo, the 18 items answered by 229 high school students (M = 16.20 years; SD = 1.23). A confirmatory factorial analysis confirmed bifactorial adjustment. MCS has evidence of validity based on internal structure, which can be used in research outside of Brazil.
摘要本研究旨在使作弊动机量表(MCS)适应巴西学生的情境,根据其内部结构收集效度证据。进行了两项研究。在研究1中,将MCS的20个项目翻译成葡萄牙语,并由10名学生进行语义评价,他们认为这些项目是可以理解的。随后,为了了解该措施的内部结构,有212名高中生(M = 16.10年;Sd = 1.02)。探索性因素分析表明,成功追求和道德启蒙两个因素的存在,饱和了18个项目。研究2旨在验证这一析因结构。229名高中生回答的18个问题(M = 16.20岁;Sd = 1.23)。确证性因子分析证实了双因子调整。MCS具有基于内部结构的有效性证据,可用于巴西以外的研究。
