Predicting Individual Differences from Brain Responses to Music using Functional Network Centrality

2022

Individual differences are known to modulate brain responses to music. Recent neuroscience research suggests that each individual has unique and fundamentally stable functional brain connections irrespective of the task they perform. 77 participants’ functional Magnetic Resonance Imaging (fMRI) responses were measured while continuously listening to music. Using a graph-theory-based approach, we modeled whole-brain functional connectivity. We then calculate voxel-wise eigenvector centrality and subsequently use it to classify gender and musical expertise using binary Support Vector Machine (SVM). We achieved a cross-validated classification accuracy of 97% and 96% for gender and musical exp…

Contributions of Nonverbal Cues to the Accurate Judgment of Personality Traits

2019

In this chapter, we summarize research on nonverbal expressions of behavior (nonverbal cues) and how they contribute to the accuracy of personality judgments. First, we present a conceptual overview of relevant nonverbal cues in the domains of facial expressions, body language, paralanguage, and appearance as well as approaches to assess these cues on different levels of aggregation. We then summarize research on the validity of nonverbal cues (what kind of nonverbal cues are good indicators of personality?) as well as the utilization of nonverbal cues (what kind of nonverbal cues lead to personality impressions?), resulting in a catalogue of those cues that drive judgment accuracy for diff…

Effects of conversation content on viewing dyadic conversations

2016

People typically follow conversations closely with their gaze. We asked whether this viewing is influenced by what is actually said in the conversation and by the viewer’s psychological condition. We recorded the eye movements of healthy (N = 16) and depressed (N = 25) participants while they were viewing video clips. Each video showed two people, each speaking one line of dialogue about socio-emotionally important (i.e., personal) or unimportant topics (matter-of-fact). Between the spoken lines, the viewers made more saccadic shifts between the discussants, and looked more at the second speaker, in personal vs. matter-of-fact conversations. Higher depression scores were correlated with les…

The perception of food products in adolescents, lay adults, and experts:A psychometric approach

2022

Almost 40% of global mortality is attributable to an unhealthy diet, and adolescents and young adults are particularly affected by growing obesity rates. How do (young) people conceptualize and judge the healthiness of foods and how are the judgments embedded in people’s mental representations of the food ecology? We asked respondents to rate a large range of common food products on a diverse set of characteristics and then applied the psychometric paradigm to identify the dimensions structuring people’s mental representations of the foods. Respondents were also asked to rate each food in terms of its healthiness, and we used the foods’ scores on the extracted dimensions to predict the heal…

Emotional user experience: Traits, events, and states☆

2015

Emotional experience has become an important topic in human-technology interaction research and design. Nevertheless, such research and design often lacks a proper explanatory basis and methodologically robust operationalisation. In this article, a conceptualisation of emotional user experience is formulated based on the appraisal theory of emotion, where the goal congruence of the interaction events and the task-independent individual traits are thought to underlie the user's emotional response. A laboratory study with N=50 participants conducting ordinary computer tasks is reported. The results suggest that subjective emotional experience depends on a number of factors relating to individ…

Individual differences in affective and cognitive processing of musical pitch

2012

Musical pitch processing has been studied extensively, but rarely in the context of affective pitch processing, or of individual differences in pitch processing. In this study, participants answered surveys measuring personality and empathy dimensions. They then listened to tonal chord sequences to determine whether they sounded correct or incorrect, and whether they sounded happy or sad, while electroencephalogram (EEG) was recorded. The last chord of each sequence could be either incorrect (containing one note which is out of tune) or correct (containing no such mistuning), and affective content was varied by having sequences resolve in major and minor modes. Personality dimension agreeab…

Discovering prominence and its role in language processing: an individual (differences) approach

2015

Abstract It has been suggested that, during real time language comprehension, the human language processing system attempts to identify the argument primarily responsible for the state of affairs (the “actor”) as quickly and unambiguously as possible. However, previous work on a prominence (e.g. animacy, definiteness, case marking) based heuristic for actor identification has suffered from underspecification of the relationship between different cue hierarchies. Qualitative work has yielded a partial ordering of many features (e.g. MacWhinney et al. 1984), but a precise quantification has remained elusive due to difficulties in exploring the full feature space in a particular language. Feat…

Bridging Skill and Task-Oriented Reading

2015

Some individual difference factors are more strongly correlated with performance on postreading questions when the text is not available than when it is. The present study explores if similar interactions occur with bridging skill, which refers to a reader's propensity to establish connections between explicit text during reading. Undergraduates read science texts using two research tools. The Reading Strategy-Assessment Tool provided a measure of bridging skill. Texts and postreading questions were presented in Read&Answer, and the availability of the text while answering was manipulated. Contrary to prior research, bridging skill was comparably correlated with performance in both availabi…

Psychophysiological stress response and coping styles to an acute laboratory stressor in healthy adults

2015

Para ahondar en la respuesta de estrés en humanos, tenemos que tener en cuenta la gran complejidad que nos caracteriza en comparación a otras especies. En humanos, los mecanismos fisiológicos involucrados en la respuesta de estrés están continuamente interactuando con las demandas del entorno, pero los factores que contribuyen a largo plazo en la adaptación de los desafíos del ambiente que nos rodea, son los factores sociales, conductuales y cognitivos. Además, deben ser consideradas las diferencias en la respuesta afectiva, cognitiva y en personalidad, así como, la edad, el sexo/género, o las hormonas sexuales. Teniendo en cuenta la literatura previa, el objetivo central de esta tesis es c…
