RESUMO

Journal editors have a large amount of power to advance open science in their respective fields by incentivising and mandating open policies and practices at their journals. The Data PASS Journal Editors Discussion Interface (JEDI, an online community for social science journal editors: www.dpjedi.org ) has collated several resources on embedding open science in journal editing ( www.dpjedi.org/resources ). However, it can be overwhelming as an editor new to open science practices to know where to start. For this reason, we created a guide for journal editors on how to get started with open science. The guide outlines steps that editors can take to implement open policies and practices within their journal, and goes through the what, why, how, and worries of each policy and practice. This manuscript introduces and summarizes the guide (full guide: https://doi.org/10.31219/osf.io/hstcx ).

RESUMO

Current research on emotion knowledge and competence emphasises the role of language. Emotion vocabulary is one of the indicators of emotion knowledge that can be objectively measured; however, the metric properties of the scores obtained in tests and tasks to measure it have seldom been adequate. In this study we designed and validated a Spanish emotion vocabulary test (MOVE) employing a corpus approach to construct cloze multiple-choice items, administered the test to a Spanish-speaking sample from two countries, Spain and Argentina, and analysed structural validity of the test items with the Rasch model measurement approach. Eighty-eight items showed adequate fit. Overall, a substantial percentage of variance was explained by a latent variable. Reliability indexes at the test, item, and person level were also adequate. As a vocabulary test, the MOVE can be used in psychological and neurological investigation, as well as in language learning research.

RESUMO

The study examined how readers integrate information from and about multiple information sources into a memory representation. In two experiments, college students read brief news reports containing two critical statements, each attributed to a source character. In half of the texts, the statements were consistent with each other, in the other half they were discrepant. Each story also featured a non-source character (who made no statement). The hypothesis was that discrepant statements, as compared to consistent statements, would promote distinct attention and memory only for the source characters. Experiment 1 used short interviews to assess participants' ability to recognize the source of one of the statements after reading. Experiment 2 used eye-tracking to collect data during reading and during a source-content recognition task after reading. As predicted, discrepancies only enhanced memory of, and attention to source-related segments of the texts. Discrepancies also enhanced the link between the two source characters in memory as opposed to the non-source character, as indicated by the participants' justifications (Experiment 1) and their visual inspection of the recognition items (Experiment 2). The results are interpreted within current theories of text comprehension and document literacy.

RESUMO

Various traditions have investigated the relationship between emotion and language. For the basic emotions view, emotional prototypes are lexically sedimented in language, evidenced in cultural convergence in emotional recognition and expression tasks. For constructionist theories, conceptual knowledge supported by language is at the core of emotions. Understanding emotion words is embedded in various interrelated constructs such as emotional intelligence, emotion knowledge or emotion differentiation, and is related to, but different from, general vocabulary. A clear advantage of Emotion Vocabulary over most emotion-related constructs is that it can be measured objectively. In two successive corpus-based studies, we tested the predictions of concordance and absolute agreement on the frequency of use of a total of 100 Spanish emotion labels in the eight main Spanish-speaking areas: Spain, Mexico-Central America, River Plate, Continental Caribbean, Andean, Antilles, Chilean, and the United States. In both studies, the intraclass correlation coefficient was statistically different from the null and very large, over .95, as was the Kendall's concordance coefficient, indicating broad consensus among the Spanish linguistic areas. From an applied perspective, our results provide supporting evidence for the similarity in frequency, and therefore cross-cultural generalizability regarding familiarity of the 100 emotion labels as item stems or as experimental stimuli without going through a process of additional adaptation. On a broader scope, these results add evidence on the role of language for emotion theories. In this regard, countries and regions compared here share the same Spanish language, but differ in several aspects in history, culture, and socio-economic structure.

RESUMO

Differential item functioning (DIF) is of the utmost importance in order to corroborate the generalized validity of test scores in different groups. DIF indicates that an item does not function equally in different groups such as age, gender or cultural ones. Our objective was to contrast the generalized validity of the Emotion Knowledge (EK) test scores in a heterogeneous Argentinian sample composed of 100 females and 100 males (age range: 18-65). Data from the original validation sample (200 Spanish participants, half of them males) were conjointly analyzed (total n = 400). Results of the Rasch Model (RM) analysis indicated that both fit to the RM and reliability (ISR = .97, PSR = .80) were adequate. Item logit measures ranged from -3.89 to 3.68, and person logit measures ranged from -1.12 to 5.09, with a mean value of 2.36. DIF was tested for gender, age, educational level and country, with a few item contrasts found to be statistically significant. Even though small significant differences in EK scores were associated with educational level (d = .25) and country (d = -.25), they became non-significant after removing the seven country-related DIF affected items. We can conclude that there is enough evidence for the generalized validity of EK test scores in Argentina. Given that recent theories of human emotion consider conceptual knowledge supported by language as constitutive of emotions, the EK test can be used in academic or applied settings where individual differences in emotional competence might be relevant.

RESUMO

Abstract Working memory is an active memory system serving the realization of complex cognitive tasks. Over the last decades' research has centered on studying the relationship of this memory system or any of its components with different cognitive functions, such as intelligence. The aim of this study is to analyze the relation between visuospatial working memory, processing speed and general intelligence, and the possible mediation role of some of these variables. To carry out this work, two studies were conducted. On Study 1 participated212 Spanish speaking college students, and a Spanish visuospatial working memory battery was designed and validated -the visuospatial Computerized Working Memory Battery (Batería Informatizada de Memoria de Trabajo Viso-Espacial; BIMeT-VE)-. On Study 2 participated 114 Spanish speaking college students, and the relationship among visuospatial working memory, processing speed and general intelligence was analyzed. The results showed that general intelligence is directly supported by the processing speed and to maintain visuospatial information for short periods of time, and indirectly by the ability to concurrently process visuospatial information.


Resumo A memória de trabalho é um sistema de memória ativo ao serviço da realização de tarefas cognitivas complexas. Nas últimas décadas as pesquisas têm-se centrado em estudar a relação entre a memória de trabalho ou seus subsistemas e outras funções cognitivas, como a inteligência. O objetivo deste estudo é analisar a relação entre a memória de trabalho visuoespacial, a velocidade de processamento e a inteligência geral, e o possível papel mediador destas variáveis. Por esta razão, foram feitos dois estudos. No primeiro desenhou-se e validou-se a Bateria Computorizada de Memória de Trabalho Visual e Espacial (BIMeT-VE) numa amostra de 212 estudantes universitários. No segundo estudo que envolveu 114 estudantes universitários analisou-se a relação entre a memória de trabalho visual e espacial, a velocidade de processamento e a inteligência geral. Os resultados mostraram que a inteligência geral está diretamente associada com a velocidade de processamento e com a habilidade de manter a informação visual e espacial a curto prazo, e indiretamente pela habilidade de processar informação visual e espacial de maneira simultânea.

RESUMO

BACKGROUND: Psychological constructionist models like the Conceptual Act Theory (CAT) postulate that complex states such as emotions are composed of basic psychological ingredients that are more clearly respected by the brain than basic emotions. The objective of this study was the construction and initial validation of Emotion Knowledge measures from the CAT frame by means of an invariant measurement approach, the Rasch Model (RM). Psychological distance theory was used to inform item generation. METHODS: Three EK tests-emotion vocabulary (EV), close emotional situations (CES) and far emotional situations (FES)-were constructed and tested with the RM in a community sample of 100 females and 100 males (age range: 18-65), both separately and conjointly. RESULTS: It was corroborated that data-RM fit was sufficient. Then, the effect of type of test and emotion on Rasch-modelled item difficulty was tested. Significant effects of emotion on EK item difficulty were found, but the only statistically significant difference was that between "happiness" and the remaining emotions; neither type of test, nor interaction effects on EK item difficulty were statistically significant. The testing of gender differences was carried out after corroborating that differential item functioning (DIF) would not be a plausible alternative hypothesis for the results. No statistically significant sex-related differences were found out in EV, CES, FES, or total EK. However, the sign of d indicate that female participants were consistently better than male ones, a result that will be of interest for future meta-analyses. DISCUSSION: The three EK tests are ready to be used as components of a higher-level measurement process.

RESUMO

RESUMEN El propósito de este trabajo consistió en estudiar la relación entre la memoria de trabajo, el conocimiento previo y la generación de inferencias en la comprensión de textos. Con este propósito, 167 estudiantes universitarios completaron pruebas de memoria de trabajo y cuestionarios sobre su conocimiento acerca del cambio climático y de astronomía; luego de la lectura de dos textos expositivos referidos a ambos temas, completaron un cuestionario sobre inferencias. Los resultados del análisis de correlaciones y del análisis de senderos muestran que si bien la memoria de trabajo y el conocimiento previo específico de dominio tienen una relación con la generación de inferencias explicativas-repositivas, hay una relación de interacción de mediación entre estas variables que explica el rol de ellas sobre la generación de inferencias.


ABSTRACT The aim of this research is to study the relationship between working memory, previous knowledge, and explanation-based inferences in expository text reading. To this effect, 167 undergraduates completed three working memory tasks, and two climate change and astronomy questionnaires, after reading two expository texts on these subjects. The results of the correlations and paths analyses show that, while working memory and specific previous domain knowledge are related to the generation of explanatory and reinstatement inferences, there is a mediation interaction relationship between these variables that explains their role in the generation of inferences.

RESUMO

IMPORTANCE: Prevention is more effective than treatment to decrease the burden of significant medical conditions such as depressive disorders, a major cause of disability worldwide. Traumatic brain injury (TBI) is a candidate for selective strategies to prevent depression given the incidence, prevalence, and functional effect of depression that occurs after TBI. OBJECTIVE: To assess the efficacy of sertraline treatment in preventing depressive disorders following TBI. DESIGN, SETTING, AND PARTICIPANTS: A double-blind, placebo-controlled, parallel-group randomized clinical trial was conducted at a university hospital from July 3, 2008, to September 17, 2012, with 24 weeks of follow-up. A consecutive sample of 534 patients aged 18 to 85 years, hospitalized for mild, moderate, or severe TBI, was eligible for the study. Ninety-four patients consented to participate and were randomized (46 to placebo and 48 to sertraline), of whom 79 (84%) completed the study. Intention-to-treat data analysis was conducted from July 1, 2014, to December 31, 2015. INTERVENTIONS: Placebo or sertraline, 100 mg/d, for 24 weeks or until development of a mood disorder. MAIN OUTCOMES AND MEASURES: Time to onset of depressive disorders, as defined by the DSM-IV, associated with TBI. RESULTS: Of the 94 patients in the study (38 female and 56 male; 92 white), the number needed to treat to prevent depression after TBI at 24 weeks was 5.9 (95% CI, 3.1-71.1; χ2 = 4.6; P = .03) for sertraline treatment vs placebo. The influence of sertraline in the course of neuropsychological variables was not detected. The intervention was well tolerated, and adverse effects were mild in both the sertraline and placebo groups. CONCLUSIONS AND RELEVANCE: Sertraline appears to be efficacious to prevent the onset of depressive disorders following TBI. Future studies should replicate these findings in a large sample of patients with TBI and depict their long-term physical, cognitive, behavioral, and functional outcomes. TRIAL REGISTRATION: clinicaltrials.gov Identifier: NCT00704379.

RESUMO

Two hypotheses about the role of the ventromedial prefrontal cortex (vmPFC) in narrative comprehension inferences, global semantic coherence versus socio-emotional perspective, were tested. Seven patients with vmPFC lesions and seven demographically matched healthy comparison participants read short narratives. Using the consistency paradigm, narratives required participants to make either an emotional or visuo-spatial inference, in which a target sentence provided consistent or inconsistent information with a previous emotional state of a character or a visuo-spatial location of an object. Healthy comparison participants made the inferences both for spatial and emotional stories, as shown by longer reading times for inconsistent critical sentences. For patients with vmPFC lesions, inconsistent sentences were read slower in the spatial stories, but not in the emotional ones. This pattern of results is compatible with the hypothesis that vmPFC contributes to narrative comprehension by supporting inferences about socio-emotional aspects of verbally described situations.

RESUMO

INTRODUCTION: Multiple sclerosis is a demyelinating neurological disease that usually gives rise to motor, perceptive, affective and cognitive disorders in patients. These symptoms can lead the person to lose his or her job and lower the quality of life of both patients and their relatives. AIM: To review the literature on demographic, clinical, cognitive, psychiatric, occupational and social variables associated with the work situation. DEVELOPMENT: Cross-sectional and longitudinal studies have detected variables related with unemployment. Empirical research has shown how physical disability, fatigue and the progression of the disease exert a clear influence on the patient's work situation. Yet, the same degree of evidence is not true for gender, depression, age, duration of the disease and cognitive variables. Little attention has been given to work characteristics such as job discrimination, employer's attitude, labour laws, colleagues' attitudes and transport problems. CONCLUSIONS: Many of the factors that determine job loss in a patient with multiple sclerosis can be identified in time to allow them to be modified or offset. The knowledge provided by the studies mentioned above makes it possible to detect patients who are at risk of losing their job so that interventions can be carried out with the aim of preventing such a situation from occurring. More particularly, the vulnerability profile includes high physical disability and fatigue, progressive development of the disease and the presence of cognitive impairment, among others.

RESUMO

La memoria de trabajo se refiere a todos aquellos mecanismos o procesos implicados en el control, regulación y mantenimiento activo de información relevante para la ejecución de tareas cognitivas complejas (Miyake & Shah, 1999); es uno de los principales factores limitantes de las capacidades de alto nivel jerárquico, como el razonamiento o la comprensión lectora. En este trabajo se informa un estudio en el que se analizaron las propiedades psicométricas de una de las tareas más conocidas para la evaluación de la capacidad de la memoria de trabajo, la Tarea de Amplitud de Lectura de Daneman y Carpenter (1980). La tarea consiste en leer un conjunto de oraciones no relacionadas entre sí, mientras se retienen sus palabras finales, y determina el máximo número de palabras finales que un participante puede recordar, que se identifica con su amplitud o span. La prueba se adaptó al español rioplatense partiendo de versiones españolas (Elosúa, Gutiérrez, García Madruga, Luque & Gárate, 1996; Gutiérrez, Jiménez & Castillo, 1996) y se administró en sesión individual a 132 voluntarios, conjuntamente con pruebas estandarizadas de memoria de corto plazo y de trabajo, tales como Amplitud de Dígitos y Amplitud Viso-Espacial de la Wechsler Memory Scale - Revised (WMS - R, Wechsler & Stone, 1987) y Ordenamiento Dígito-Letra de la Wechsler Adult Intelligence Scale III (WAIS III - Wechsler, 1987). La tarea de Amplitud de Lectura mostró una alta fiabilidad. Con respecto a su validez, se obtuvieron correlaciones significativas con tareas de memoria verbal, pero no así con tareas de memoria viso-espacial.


In the study of human behavior, working memory has been seen as a central construct (Conway, Kane, Bunting, Hambrick, Wilhelm, & Engle, 2005) since the cognitive revolution took place. Working memory refers to those mechanisms or processes that are involved in the control, regulation, and active maintenance of task-relevant information in the service of complex cognition (Miyake & Shah, 1999), and is considered one of the main limiting factors for complex abilities such as reasoning or reading comprehension. Methodologically, the Reading Span Task (Daneman & Carpenter, 1980) has proven to be both a reliable and valid measure of working memory capacity, and is a widely used measure. The purpose of this study was to develop a local adaptation of the Reading Span Task, based on two previous Spanish versions (Gutiérrez, Jiménez, & Castillo, 1996; Elo súa, Gutiérrez, García Madruga, Luque, & Gárate, 1996), whose psychometric properties were not known. In both cases, the Reading Span capacity was significantly correlated with measures of reading comprehension. However, the psychometric properties of the Reading Span Task were not analyzed. The task requires participants to read a set of unrelated sentences, each of which is between 12 and 14 words long, one sentence at a time, at their own pace. Sentences are arranged in 4 sets of 2, 3, 4, and 5 sentences. There are three different trials at each set-size (number of sentences) level. After having read all the sentences in each set, participants try to recall the final word of each sentence. Working memory capacity is both the maximum number of sentences for which the participant can recall the final word (Span) and the total number of sentence-final words recalled (Conway et al., 2005). The task was administered in one session to 132 undergraduates at the University of Buenos Aires (UBA), along with other standardized short-term and working memory tests, Digit Span and Visuo-Spatial Span from the Wechsler Memory Scale - Revised (Wechsler & Stone, 1987), and Letter- Number Sequencing from the Wechsler Adult Intelligence Scale III (Wechsler, 2003). The Reading Span Task showed high reliability (α = .95). The percentile analysis shows that those participants that obtained a Span of 2 or recalled 6 words fall in the 25th percentile, while those that obtained scores above a Span of 3.5 and recalled more than 24 words fall above the 75th percentile. The correlation analysis shows that the Reading Span Task has positive and significant correlations with verbal memory tasks (measured by Span, Forward Digit Span r = .408; p < .01; Backward Digit Span r = .502; p < .01; Letter-Number Sequencing r = .504; p < .01; measure by Number of sentencefinal words recalled, Forward Digit Span r = .416; p < .01; Backward Digit Span r = .496; p < .01; Letter-Number Sequencing r = .489; p < .01) , but not with visuo-spatial memory tasks (measure by Span, Forward Visuo-Spatial Span r = .169; p = n.s.; Backward Visuo-Spatial Span r = .018; p = n.s.; measure by Number of sentence-final words recalled, Forward Visuo-Spatial Span r = .189; p < .05; Backward Viso- Spatial Span r = .032; p = n.s.). A factor analysis showed the separation of the two factors involved in the tasks: a verbal factor whose capacity is affected by the Reading Span Task, Digit Span and Letter - Number Sequencing tasks, and a visuo-spatial factor whose capacity is affected by the visuo-spatial amplitude tasks. Results indicate that the Reading Span Task can be considered an appropriate, valid and reliable measure of the capacity of verbal working memory, useful for doing research on cognitive processes and for neuropsychological assessment.
