Abnormalities in the processing of emotional prosody from single words in schizophrenia

Background: Abnormalities in emotional prosody processing have been consistently reported in schizophrenia and are related to poor social outcomes. However, the role of stimulus complexity in abnormal emotional prosody processing is still unclear. Method: We recorded event-related potentials in 16 patients with chronic schizophrenia and 16 healthy controls to investigate: 1) the temporal course of emotional prosody processing; and 2) the relative contribution of prosodic and semantic cues in emotional prosody processing. Stimuli were prosodic single words presented in two conditions: with intelligible (semantic content condition—SCC) and unintelligible semantic content (pure prosody condition—PPC). Results: Relative to healthy controls, schizophrenia patients showed reduced P50 for happy PPC words, and reduced N100 for both neutral and emotional SCC words and for neutral PPC stimuli. Also, increased P200 was observed in schizophrenia for happy prosody in SCC only. Behavioral results revealed higher error rates in schizophrenia for angry prosody in SCC and for happy prosody in PPC. Conclusions: Together, these data further demonstrate the interactions between abnormal sensory processes and higher-order processes in bringing about emotional prosody processing dysfunction in schizophrenia. They further suggest that impaired emotional prosody processing is dependent on stimulus complexity.

The music of language: an ERP investigation of the effects of musical training on emotional prosody processing

Recent studies have demonstrated the positive effects of musical training on the perception of vocally expressed emotion. This study investigated the effects of musical training on event-related potential (ERP) correlates of emotional prosody processing. Fourteen musicians and fourteen control subjects listened to 228 sentences with neutral semantic content, differing in prosody (one third with neutral, one third with happy and one third with angry intonation), with intelligible semantic content (semantic content condition--SCC) and unintelligible semantic content (pure prosody condition--PPC). Reduced P50 amplitude was found in musicians. A difference between SCC and PPC conditions was found in P50 and N100 amplitude in non-musicians only, and in P200 amplitude in musicians only. Furthermore, musicians were more accurate in recognizing angry prosody in PPC sentences. These findings suggest that auditory expertise characterizing extensive musical training may impact different stages of vocal emotional processing.

Fathers’ emotional involvement with the neonate: impact of the umbilical cord cutting experience

Aims. This paper is a report on a study analysing the effect of the umbilical cord cutting experience on fathers’ emotional involvement with their infants. Background. Participation in childbirth offers an opportunity for father and mother to share the childbirth experience, so it is vital that midwives improve the fathers’ participation in this event. Design. A quasi-experimental study with a quantitative methodology was implemented. Methods. One hundred and five fathers were recruited as part of a convenience sample in a Maternity Public Hospital in a Metropolitan City in Portugal, between January and May of 2008. The Bonding Scale, the Portuguese version of the ‘Mother-to-Infant Bonding Scale’ was used to evaluate the fathers’ emotional involvement with the neonate at different moments: before childbirth, first day after childbirth and first month after childbirth. After childbirth, the fathers were divided into three separate groups depending on their umbilical cord cutting experience. Results. The results demonstrate that the emotional involvement between father and child tends to increase during the first days after childbirth and to decrease when evaluated 1 month after birth, for fathers who did not cut the umbilical cord. However, fathers who cut the umbilical cord demonstrate an improvement in emotional involvement 1 month later. Conclusion. Results suggest that the umbilical cord cutting experience benefits the father’s emotional involvement with the neonate, supporting the benefits of his participation and empowerment in childbirth.

Mother's stress, mood and emotional involvement with the infant: 3 months before and 3 months after childbirth

Adverse effects of maternal anxiety and depression are well documented, namely on the foetus/child behaviour and development, but not as much attention has been given to the mother's emotional involvement with the offspring. To study mother's prenatal and postpartum stress, mood and emotional involvement with the infant, the State-Trait Anxiety Inventory, the Edinburgh Postnatal Depression Scale and the Mother-to-Infant Bonding Scale were filled in and cortisol levels were measured, 3 months before and 3 months after childbirth, in a sample of 91 Portuguese women. From pregnancy to the postpartum period, mother's cortisol levels, anxiety and emotional involvement toward the child decrease. No significant change was observed regarding mother's depression. Mother's depression predicted a worse emotional involvement before childbirth, while mother's anxiety predicted a worse emotional involvement with the infant after childbirth. Additionally, pregnant women with a worse emotional involvement with the offspring are at risk of poorer emotional involvement with the infant and higher anxiety and depression at 3 months postpartum. It should be given more attention to mother's poor emotional involvement with the offspring during pregnancy, as it interferes with her emotional involvement with the infant and her psychological adjustment 3 months after childbirth.

Mother-to-infant emotional involvement at birth

Objectives. To study mother-to-infant emotional involvement at birth, namely factors (socio-demographics, previous life events, type of delivery, pain at childbirth, support from partner, infant characteristics, early experiences with the newborn, and mother’s mood) that interfere with the mother’s positive, negative and not clear emotions toward the newborn. Methods. The Bonding Scale (an extended Portuguese version of the ‘New Mother-to-Infant Bonding Scale’) and the Edinburgh Postnatal Depression Scale were administrated during the first after delivery days to 315 mothers recruited at Ju´lio Dinis Maternity Hospital (MJD, Porto, Portugal). Results. A worse emotional involvement with the newborn was observed when the mother was unemployed, unmarried, had less than grade 9, previous obstetrical/psychological problems or was depressed, as well as when the infant was female, had neonatal problems or was admitted in the intensive care unit. Lower total bonding results were significantly predicted when the mother was depressed and had a lower educational level; being depressed, unemployed and single predicted more negative emotions toward the infant as well. No significant differences in the mother-to-infant emotional involvement were obtained for events related to childbirth, such as type of delivery, pain and partner support, or early experiences with the newborn; these events do not predict mother’s bonding results either. Conclusion. The study results support the need for screening and supporting depressed, unemployed and single mothers, in order to prevent bonding difficulties with the newborn at birth.

Children's play and leisure : connections with emotional competence

O jogo e o lazer são elementos importantes para o desenvolvimento das crianças. O objetivo geral desta tese foi o de investigar o modo como o jogo e o lazer estão relacionados com diferentes aspetos das competências emocional e social das crianças e jovens. Nesta tese foram investigados três aspetos do jogo: o tempo, a forma e o nível social, diferentes formas de lazer, e vários elementos chave do funcionamento sócio-emocional, através da combinação de observações naturalistas, tarefas, questionários e de um método inovador de mensuração, baseado em Identificação por Rádio-Frequência. O panorama que surge dos estudos incluídos nesta tese é que o jogo e o lazer estão relacionados com o funcionamento sócio-emocional, embora de formas distintas, e por vezes inesperadas. Os estudos no recreio revelaram que as crianças envolvem-se predominantemente no jogo de atividade física. Contudo, enquanto que uma forma de jogo de atividade física, o jogo de exercício, foi associado a melhor competência social, a outra forma, o jogo de luta-e-perseguição, foi associado à agressividade. O facto de o jogo de faz-de-conta, em estudos anteriores, ter sido maioritariamente estudado em espaços interiores, pode explicar o porquê das associações negativas encontradas entre o jogo de faz-de-conta, quer em grupo, quer solitário (nas raparigas) e a competência sócio-emocional, que contrastam com a literatura. De facto, as crianças que não conseguem juntar-se aos seus pares no jogo de exercício podem optar por esta alternativa, o que sugere que crianças socialmente competentes poderão retirar maior vantagem das oportunidades existentes, adaptando melhor os seus comportamentos de jogo. As crianças mais velhas têm geralmente mais liberdade de decisão sobre o seu tempo de lazer. Quando perguntámos às crianças mais velhas e aos adolescentes como passavam a sua semana, as atividades de ecrã destacaram-se. Contudo, as atividades de ecrã e as atividades intelectuais foram relacionadas a mais problemas de saúde mental, enquanto que as atividades desportivas foram associadas a melhor saúde mental. Concluindo, diferentes formas de jogo e de lazer podem ter diferentes funções, de uma forma positiva ou negativa, dependendo da situação em que a criança se encontra.

El impacto de las normas y de la ideología sobre el procesamiento emocional, motivacional y cognitivo del comportamiento político de las elites de poder y la ciudadanía de Córdoba. Norms and ideologies impact on the emotional, motivational and cognitive processesing of power elite and citizen political behavior in Cordoba.

El presente estudio pretende arribar a la construcción de un modelo explicativo del comportamiento político a partir de la contribución que los marcos sociales (norma sociales, normas de ciudadanía, ideología, confianza política) y sociocognitivos (inteligencia afectiva, interés político, eficacia política, conocimiento político, sentimiento de comunidad) mostraron, en términos de relaciones entre las variables, sobre el mismo. Nuestra atención se centra no sólo al comportamiento político de la ciudadanía -que es donde se desarrollaron la mayor parte de los estudios-, sino a las elites de poder constitutivas del sistema político (jueces, legisladores provinciales y representantes de instituciones del gobierno y de organismos no gubernamentales). Asimismo, pretende establecer las diferencias que puedan evidenciarse en torno a la relación de estas variables con el comportamiento político entre los distintos colectivos estudiados en el ámbito de la ciudad de Córdoba. Para ello se realizara una primera etapa de estudio instrumental, con el objeto de analizar las propiedades psicométricas de los instrumentos a utilizar en la operacionalización de las variables. Para ello se tomara una muestra accidental de 250 personas entre 18 y 65 años de edad. Posteriormente, se realizarán dos etapas de estudio ex post facto, con la finalidad de construir los modelos planteados. En la primera de ellas, se trabajará con una muestra accidental de 100 representantes de los grupos de poder estudiados y en la segunda con una muestra probabilística de 500 ciudadanos cordobeses entre 18 y 65 años de edad.

Mecanismos neurobiologicos involucrados en la sensibilizacion emocional inducida por abstinencia a drogas de abuso y estrés. Neurobiological mechanisms involved in emotional sensitization induced by withdrawal from drugs of abuse and stress.

El objetivo principal de este proyecto es estudiar los mecanismos neurobiológicos involucrados en el proceso de sensibilización emocional inducido por la abstinencia a drogas de abuso o por la exposición a un estímulo estresante de caracteristicas incontrolables. El modelo animal de sensibilización a utilizar en este proyecto es la facilitación en la formación de memoria de miedo producida por dichos tratamientos. Nuestra hipótesis sugiere que este proceso es el resultado de un mecanismo desinhibitorio de las interneuronas GABAérgicas del complejo basolateral de la amigdala. Por lo tanto se proponen los siguientes experimentos: 1) El estudio del curso temporal del efecto facilitador sobre la formación de una nueva memoria de miedo luego de la abstinencia a drogas o la exposición a un estímulo estresante (inmovilización). 2) La evaluación de la liberación"in vivo" de dopamina del complejo basolateral de la amigdala durante la adquisición y la expresión de la memoria de miedo en animales previamente expuestos a la abstinencia o al estres. 3) El estudio de la infusión local de antagonistas de receptores dopaminérgicos en el complejo basolateral de la amígdala (BLA) o en el nucleo central de la amígdala (CeA) antes del estrés sobre la adquisición y la expresión de una memoria de miedo. 4) La determinación de la actividad de ERK 1/2 y CREB en el complejo basolateral de la amigdala o en el nucleo central de la amígdala durante la adquisición y la expresión de una memoria de miedo en animales abstinentes o estresados. 5)El estudio de la infusión local de inhibidores de la MEK 1/2 en el complejo basolateral de la amigdala o en el nucleo central de la amígdala antes del estrés sobre la adquisición y la expresión de una memoria de miedo. La facilitación para generar memorias de miedo podría ser un componente crítico del síndrome de abstinencia al etanol responsable de las altas tasas de recurrencia asociadas con el alcoholismo. Por lo tanto se investigará el efecto de la evocación de la memoria de miedo sobre la autoadministración de etanol utilizando un paradigma de libre elección entre agua y soluciones de concentración creciente de etanol en animales en abstinencia al etanol. Con el objeto de investigar si las propiedades reforzantes del etanol están involucradas en el potencial aumento de la ingesta de etanol inducido por la evocación de una memoria de miedo, se evaluará el efecto reforzante de etanol utilizando el paradigma de preferencia por un contexto asociado al etanol.

Emotional and user-specific cues for improved analysis of naturalistic interactions

... ist es nicht möglich, die in dieser Arbeit identifizierten offenen Fragen restlos zu klären. Die Erweiterung der puren akustischen Emotionserkennung durch Berücksichtigung von anderen Modalitäten, Sprechercharakteristiken, Feedbacksignalen und Persönlichkeitsmerkmalen erlaubt es jedoch, länger andauernde natürliche Interaktionen zu untersuchen und dialogkritische Situationen zu erkennen. Technische Systeme, die diese erweiterte Emotionserkennung nutzen, passen sich an ihren Nutzer an und werden so zu seinem Begleiter und letztendlich zu seinem Companion.
