    Este trabajo proporciona los valores normativos españoles de las 358 imágenes que forman los conjuntos 15 a 20 del International Affective Picture System (IAPS). En este estudio participaron 811 estudiantes universitarios (521 mujeres) que evaluaron las imágenes en las dimensiones emocionales de valencia, activación y dominancia. Las correlaciones entre las evaluaciones estadounidenses y las españolas en todas las dimensiones fueron altamente significativas y, como en Estados Unidos, la distribución de las imágenes en el espacio bidimensional afectivo definido por las dimensiones de valencia y activación adoptó la típica forma de boomerang. Los resultados confirmaron, asimismo, las diferencias de género encontradas en Estados Unidos en las evaluaciones de las imágenes aversivas. Estos resultados son totalmente consistentes con los obtenidos en la primera y segunda parte de la adaptación española, y demuestran que la estandarización del IAPS en nuestro país ha sido adecuada. Por último, se ratificaron las pequeñas diferencias transculturales encontradas en las evaluaciones de activación y dominancia: los españoles tendieron a asignar a las imágenes mayores puntuaciones en activación y menores en dominancia que los estadounidenses. Estos datos apoyan los estereotipos culturales de estos países y sugieren que el IAPS podría ser un indicador fiable de diferencias transculturales en la disposición emocional.

    Identification of emotions and physiological response in individuals with moderate intellectual disability
    (Taylor & Francis, 2019-08-27) Agustín Ernesto Martínez-González; Veas Iniesta, Alejandro; Psicología Evolutiva y de la Educación; Facultades de la UMU::Facultad de Psicología y Logopedia
    According to Ekman’s model, the basic emotions are anger, disgust, fear, happiness, sadness, and surprise. These emotions are universal and have an adaptative function. However, studies on these emotions among individuals with moderate intellectual disability (MID) are limited, mainly owing to issues in sample size and sample homogeneity. The present study aimed to explore differences between a MID group (n = 10) and a non-MID control group (n = 10) in 1) the identification of basic emotions; and 2) the physiological response with images related to fear, happiness, sadness, anger, and disgust, as well as images with neutral and sexual content. A total of 29 images from The International Affective Picture System and a biofeedback measurement system were used. The results showed no statistically significant differences in the identification of the basic emotions of fear, sadness, and disgust. However, statistically significant differences were found for happiness (p = .008), anger (p = .02), and neutral images (p = .02), and minor statistically significant differences were found for images with sexual content (p < .01) in MID individuals with respect to the control group. The MID group’s physiological response was lower compared with the control group, with statistically significant differences for all emotional visual stimuli. This preliminary study showed important and interesting results for the study of emotions and sexuality in MID. Future studies should consider the sample size, sex and age comparisons, and the different levels of intellectual disability.

    Negative bias in the perception and memory of Emotional Information in Alzheimer Disease
    (SAGE Publications, 2017-05) Gómez García, Juan; Gómez Gallego, María; Atención Sociosanitaria
    Abstract Background: There is some controversy about the ability of patients with Alzheimer disease (AD) to experience and remember emotional stimuli. This study aims to assess the emotional experience of patients with AD and the existence of emotional enhancement of memory. We also investigated the influence of affective state on these processes. Methods: Sixty pictures from the International Affective Picture System were administered to 106 participants (72 patients with AD and 54 controls). Participants performed immediate free recall and recognition tasks. Positive and Negative Affect Schedule was used to assess the participants’ current affect. Results: Patients identified the valence of unpleasant pictures better than of others pictures and experienced them as more arousing. Patients and controls recalled and recognized higher number of emotional pictures than of neutral ones. Patients discriminated better the unpleasant pictures. A mood congruent effect was observed on emotional experience but not on memory. Positive affect was associated with better immediate recall and with a more liberal response bias. Conclusion: Patients with AD can identify the emotional content of the stimuli, especially of the unpleasant ones, and the emotional enhancement of memory is preserved. Affective state does not explain the differences in the processing and memory of emotional items between patients and controls.
