Recognition of static and dynamic facial expressions: Influences of sex, type and intensity of emotion

Ecological validity of static and intense facial expressions in emotional recognition has been questioned. Recent studies have recommended the use of facial stimuli more compatible to the natural conditions of social interaction, which involves motion and variations in emotional intensity. In this study, we compared the recognition of static and dynamic facial expressions of happiness, fear, anger and sadness, presented in four emotional intensities (25 %, 50 %, 75 % and 100 %). Twenty volunteers (9 women and 11 men), aged between 19 and 31 years, took part in the study. The experiment consisted of two sessions in which participants had to identify the emotion of static (photographs) and dynamic (videos) displays of facial expressions on the computer screen. The mean accuracy was submitted to an Anova for repeated measures of model: 2 sexes x [2 conditions x 4 expressions x 4 intensities]. We observed an advantage for the recognition of dynamic expressions of happiness and fear compared to the static stimuli (p < .05). Analysis of interactions showed that expressions with intensity of 25 % were better recognized in the dynamic condition (p < .05). The addition of motion contributes to improve recognition especially in male participants (p < .05). We concluded that the effect of the motion varies as a function of the type of emotion, intensity of the expression and sex of the participant. These results support the hypothesis that dynamic stimuli have more ecological validity and are more appropriate to the research with emotions.

Assessment of social cognition in schizophrenia through the “Reading the Mind in the Eyes” test. Implications for rehabilitation

Introduction: Schizophrenia is a serious and chronic mental illness that has effect on cognitive and social functioning of a person who suffers it. Recent research points out that social cognition subprocesses, such as Theory of Mind, social perception or emotional processing, have to do with some problems that patients show in their social adjustment. Aim: Assessing ability of recognizing mental states from facial expressions in schizophrenia patients compared to a control group. Subjects and methods: 17 stable schizophrenia patients who are aware of the illness and 17 healthy people, with the same age and sociocultural level, took the “Reading the Mind in the Eyes” Test Revised Version of Baron- Cohen. Results: Compared with the control group, subjects with schizophrenia showed much lower scores. Conclusions: It is confirmed that schizophrenia patients have impairments to understand facial expressions, especially from the eyes. That is typical of this illness, so it is necessary to do interventions at that point. Furthermore, inability to recognize emotions, as a domain of social cognition, contributes to deficit in functional outcome in schizophrenia. Finally, some treatment programs are put forward.

Gender differences among undergraduates in the recognition of emotional facial expressions

The perceptive accuracy of university students was compared between men and women, from sciences and humanities courses, to recognize emotional facial expressions. emotional expressions have had increased interest in several areas involved with human interaction, reflecting the importance of perceptive skills in human expression of emotions for the effectiveness of communication. Two tests were taken: one was a quick exposure (0.5 s) of 12 faces with an emotional expression, followed by a neutral face. subjects had to tell if happiness, sadness, anger, fear, disgust or surprise was flashed, and each emotion was shown twice, at random. on the second test 15 faces with the combination of two emotional expressions were shown without a time limit, and the subject had to name one of the emotions of the previous list. in this study, women perceived sad expressions better while men realized more happy faces. there was no significant difference in other emotions detection like anger, fear, surprise, disgust. Students of humanities and sciences areas of both sexes, when compared, had similar capacities to perceive emotional expressions

Review about neuropsychological processing of tonal attributes of music in the Western context

Many discussions about the music processing have occurred over the years. It is stated, on one hand, the existence of a single joint for grasping the music or any of its attributes by the Central Nervous System. Furthermore, it is claimed also the existence of multiple and diverse systems to understand each aspect of music. In general, model-independent set, studies focusing on the processing of sound components, specifically the musical tones, can significantly clarify the basic functioning of the auditory system and other higher brain functions. In this sense, one of the most prominent approaches in the study of sensory and perceptual processes of hearing, or changed unharmed, has been Neuroscience, which is interested in the interaction between the brain areas corresponding to different cognitive processes. Thus, the purpose of this study was to review the studies that dealt processing models of the attributes of tonal Western music, based on the conception that neuropsychological neural structures are interdependent sensory pathways.

Narración, emociones e identidad. Una lectura epistemológica y hermenéutica

El propósito de este artículo es presentar tres argumentos en torno al papel que las emociones y los procesos de narración tienen en la construcción de la identidad moral. En primer lugar, se sugiere que la comprensión cartesiana de la identidad moderna rechaza el valor que las emociones y los sentimientos tienen en la formulación de juicios normativos. En este sentido, se argumentará que necesitamos una perspectiva epistemológica distinta. En segundo lugar, se revisará la relación existente entre la identidad narrativa y las tres formas de la mímesis en Tiempo y narración. Nuestro análisis tiene el propósito de mostrar la importancia que porque se argumentará que el punto de vista hermenéutico abre la puerta a un horizonte distinto de la acción humana que incluye las emociones y los sentimientos. Finalmente, se expondrá el concepto de frameworks en el pensamiento de Charles Taylor, por la siguiente razón: la noción frameworks nos proporciona un punto de articulación entre la cuestión de la identidad y la teoría hermenéutica sobre los conceptos mencionados y el sentido de la vida.---Narrative, emotions and identity. An epistemological and hermeneutical readingThe purpose of this article is to explain three arguments about the role that emotions and the process of narration have in the construction of moral identity. First, I suggest that Cartesian comprehension of modern identity rejects the value that emotions and feelings have in formulations of normative judgments. In this sense I will argue that we need a different epistemological perspective. Second, I will review the relation between narrative identity and the three forms of mimesis in Time and Narrative. Our inquiry into them has the purpose of showing the importance that they have in many basic fields of application in social science, because I consider that the hermeneutical point of view opens the gate to a comprehensive perspective of human action, and it includes emotions and feelings. Finally, I will expose the concept of “Frameworks” in Charles Taylor´s thought for the following reason: “Frameworks” provides a point of articulation between question of identity and hermeneutical theory about the emotions, feelings and meaning of live.Key words: narrative identity, hermeneutical theory, emotions, feelings, normative judgments---Narração, emoções e identidade.

La marimba sí paga en Cali: Apropiaciones de las músicas de marimba como estrategia cultural en escenarios de industria cultural

El texto es el resultado del trabajo de investigación con dos agrupaciones musicales de la ciudad de Cali, durante el 2013 y el 2015. Hace una reflexión sociológica sobre la relación entre economía y cultura, a través de las apropiaciones que hacen estos músicos de las músicas de marimba del Pacífico del sur de Colombia, para posicionarse en escenarios de industria cultural. Con una metodología cualitativa basada en la interacción, estudia las trayectorias, prácticas y discursos de estos grupos que se consolidan en las estrategias que utilizan para ingresar en estos escenarios construidos como producto de fenómenos macrosociales globales y locales que permiten la transformación de la música como una herramienta mediadora para contar la cotidianidad que estas bandas viven en su ciudad.
