Drawings of depressed inpatients: Intentional and unintentional expression of emotional states
1998
Twenty-six patients, aged 21 to 63, hospitalized for depression, and 26 control individuals were asked to make a "funny" and a "sad" drawing, which were scored on 22 variables describing their formal aspects and contents. Results show that drawings of individuals with depression differ from those of control participants on a wide range of variables, sometimes very significantly. Prediction of participants' groups based on eight variables obtained by discriminant analysis was correct in 98% of cases. Results support the usefulness of asking for the two kinds of drawings and suggest that depression is better detected through formal aspects of drawings than through their contents.
Facial Expressions to Evaluate Advertising: A Laboratory versus Living Room Study
2017
In recent years researchers have shown growing interest in the impact of emotions in television commercials and in advertising in general (Park and Thorson, 1990). Emotions also influence the attitude towards the brand and to the ad (Batney and Ray, 1986; Edell and Burke, 1987; Derbaix, 1995), increase the attention of the advertisement (Olney, Hobrook and Bartra, 1991), and brand recall (Stayman and Batra, 1991).
La Comprensión Asíncrona de las Emociones Básicas: un Estudio Longitudinal con Niños de 3 a 5 Años
2021
El presente estudio tiene como finalidad explorar la trayectoria evolutiva de la comprensión de cuatro emociones en niños de tres a cinco años. Sabemos que los niños identifican las expresiones faciales y después entienden la causa de las emociones, pero ¿las emociones se comprenden a la vez, en el mismo momento evolutivo? Para llevar a cabo este estudio se evaluó de forma longitudinal a un grupo de 103 niños y niñas entre los 3 y los 5 años. A través del Test de Comprensión Emocional se midieron los componentes de identificación de la expresión emocional y el conocimiento de la causa de cuatro emociones –tristeza, alegría, enfado y miedo– a lo largo de los tres años. Los resultados confirm…
Can sad music really make you sad? Indirect measures of affective states induced by music and autobiographical memories
2012
The present study addressed music’s disputed ability to induce genuine sadness in listeners by investigating whether listening to sad music can induce sadness-related effects on memory and judgment. Related aims were to explore how the different mechanisms of music-induced emotions are involved in sadness induced by familiar, self-selected music and unfamiliar, experimenter-selected music, and whether the susceptibility to music-induced sadness is associated with trait empathy. One hundred twenty participants were randomly assigned into four conditions with different tasks: listening to unfamiliar sad or neutral music, or to self-selected sad music, or recalling a sad autobiographical event…
Coarse scales are sufficient for efficient categorization of emotional facial expressions: Evidence from neural computation
2010
The human perceptual system performs rapid processing within the early visual system: low spatial frequency information is processed rapidly through magnocellular layers, whereas the parvocellular layers process all the spatial frequencies more slowly. The purpose of the present paper is to test the usefulness of low spatial frequency (LSF) information compared to high spatial frequency (HSF) and broad spatial frequency (BSF) visual stimuli in a classification task of emotional facial expressions (EFE) by artificial neural networks. The connectionist modeling results show that an LSF information provided by the frequency domain is sufficient for a distributed neural network to correctly cla…
Video-based Pain Level Assessment: Feature Selection and Inter-Subject Variability Modeling
2018
Automatic pain level assessment, based on video features, may provide clinically-relevant, objective measures of pain intensity. In various clinical contexts accurate pain level estimation by health care personnel is challenging. This problem is compounded by considerable inter- and intra-individual variability of both perceived pain levels and of the associated facial expressions, especially at low pain levels. Thus, providing objective video-based indices for pain level assessment is a rather computationally challenging problem. In the present work both geometric and color-based features were extracted. The most informative features were identified with lasso regression, and subject varia…
Towards Psychologically based Personalised Modelling of Emotions Using Associative Classifiers
2016
Learning environments, among other user-centred applications, are excellent candidates to trial Computational Emotions and their algorithms to enhance user experience and to expand the system usability. However, this was not feasible because of the paucity in affordable consumer technologies that support the requirements of systems with advanced cognitive capabilities. Microsoft Kinect provides an accessible and affordable technology that can enable cognitive features such as facial expressions extraction and emotions detection. However, it comes with its own additional challenges, such as the limited number of extracted Animation Units (AUs). This paper presents a new approach that attempt…
QUALITATIVE FACTORS OF FACIAL EXPRESSION
1964
Using the semantic differential technique as scaling method, the basic factors of qualitative variation of facial expression were investigated with 30 Frois-Wittman pictures. Three factors were obtained; these were interpreted with the aid of a separate naming experiment. The factors correspond to the facial expressions associated with the emotional states of hate (anger), pleasure and contempt. The results are in fairly good agreement with those previously obtained by Schlosberg and by Nummenmaa & Kauranne.
The Power of Smiling. How Politicians’ Displays of Happiness Affect Viewers’ Gaze Behavior and Political Judgments
2019
It is a common assumption that facial expressions of politicians, such as a smile, are powerful tools to draw attention and evoke positive impressions. However, previous research has not fully linked politicians’ nonverbal behavior, viewers’ visual attention and their political impression formation. To address this gap, the research presented in this chapter uses a multi-method design to explore the role of a politician’s smiling for viewers’ judgments about him. More precisely, a laboratory study examined the visual attention (eye-tracking; n = 122) and spontaneous judgments of viewers (continuous response measurement; n = 125) while the participants were exposed to an excerpt of a German …
The Emotional Modulation of Facial Mimicry: A Kinematic Study
2018
It is well-established that the observation of emotional facial expression induces facial mimicry responses in the observers. However, how the interaction between emotional and motor components of facial expressions can modulate the motor behavior of the perceiver is still unknown. We have developed a kinematic experiment to evaluate the effect of different oro-facial expressions on perceiver's face movements. Participants were asked to perform two movements, i.e., lip stretching and lip protrusion, in response to the observation of four meaningful (i.e., smile, angry-mouth, kiss, and spit) and two meaningless mouth gestures. All the stimuli were characterized by different motor patterns (m…
