THE MODERATING EFFECT OF NEED FOR AFFECT AND COGNITION ON THE RELATION BETWEEN PERSUASIVE COMMUNICATION ABOUT LOCKDOWN AND ATTITUDES TOWARD IT

2022

2015

Mental imagery, seeing with the mind’s eyes, can induce stronger positive as well as negative affect compared to verbal processing. Given this emotion-amplifying effect, it appears likely that mental images play an important role in affective disorders. According to the subcomponents model of depression, depressed mood is maintained by both negative imagery (which amplifies negative mood) and less efficient positive imagery processes. Empirical research on the link between mental imagery and affect in clinical depression, however, is still sparse. This study aimed at testing the role of mental imagery in depression, using a modified version of the Affect Misattribution Procedure (AMP) and t…

Working memory performance is tied to stimulus complexity

2021

1. Summary Working memory is the cognitive capability to maintain and process information over short periods. Recent behavioral and computational studies have shown that increased visual information of the presented stimulus material is associated with enhanced working memory performance. However, the underlying neural correlates of this association are unknown. To identify how stimuli of different visual information levels affect working memory performance, we conducted behavioral experiments and single unit recordings in the avian analog of the prefrontal cortex, the nidopallium caudolaterale (NCL). On the behavioral level, we confirmed that feature-rich complex stimuli demonstrated highe…

FRN and P3 during the Iowa gambling task: The importance of gender.

2020

Previous research has shown gender-related psychobiological differences in risky and competitive strategies that affect win and loss outcomes. In addition, some studies have found differences in the decision-making process, with women taking longer to reach the same performance as men. However, the underlying neural mechanisms remain unclear. The present study aimed to investigate gender differences in behavioral performance and neural correlates during a decision-making task, the Iowa Gambling Task (IGT). Forty healthy young adults (23 men and 17 women) performed the IGT while the feedback-related negativity (FRN) and P3 were recorded as neural correlates of feedback processing. No gender …

Psychological models of development of idiopathic environmental intolerances: Evidence from longitudinal population-based data.

2021

Abstract The origin of idiopathic environmental intolerances (IEIs) is an open question. According to the psychological approaches, various top-down factors play a dominant role in the development of IEIs. The general psychopathology model assumes a propensity towards mental ill-health (negative affectivity) increases the probability of developing IEIs. The attribution model emphasizes the importance of mistaken attribution of experienced somatic symptoms; thus, more symptoms should lead to more IEIs. Finally, the nocebo model highlights the role of expectations in the development of IEIs. In this case, worries about the harmful effects of environmental factors are assumed to evoke IEIs. We…

The Creative Class Revisited: Does the Creative Class Affect the Birth Rate of High-tech Firms in Nordic Countries?

2015

In the new knowledge-based economy, the ability of both firms and regions to adapt to the changes in their external environment and to remain competitive is closely related to their capacity to innovate and continuously renew the existing structures and knowledge bases. With respect to this, dense concentrations of knowledge-intensive industries and related activities are usually considered to be propitious environments from which new innovations can emerge. In such environments, the ability to attract talented, highly skilled labor is crucial for the success of regions. Employees who possess and provide know-how and creativity play a leading role in knowledge-intensive production and inno…

Combining Inter-Subject Modeling with a Subject-Based Data Transformation to Improve Affect Recognition from EEG Signals

2019

Existing correlations between features extracted from Electroencephalography (EEG) signals and emotional aspects have motivated the development of a diversity of EEG-based affect detection methods. Both intra-subject and inter-subject approaches have been used in this context. Intra-subject approaches generally suffer from the small sample problem, and require the collection of exhaustive data for each new user before the detection system is usable. On the contrary, inter-subject models do not account for the personality and physiological influence of how the individual is feeling and expressing emotions. In this paper, we analyze both modeling approaches, using three public repositories. T…

Le temps du désir : ontologies de l'imaginaire et de l'affectivité chez Sartre, Merleau- Ponty et Grimaldi

2013

This study aims at confronting the ontologies of the imaginary of Sartre, Merleau-Ponty and Grimaldi. Following the path of a critical assessment of Bergsonism, each of these philosophies develops by granting ontological value to the negative, and through a reconsideration of the meaning of temporality. A new approach of negativity emerges from the reflection on the status of the image and further, upon the relationships between real and imaginary, past and present, conscious and subconscious. Merleau-Ponty and Grimaldi thus reject dialectics of being and nothingness in favour of the idea of a negativity thoroughly penetrating being itself; the first one opening the way for a phenomenologic…

In COVID-19 Health Messaging, Loss Framing Increases Anxiety with Little-to-No Concomitant Benefits: Experimental Evidence from 84 Countries

2022

Contains fulltext : 284232.pdf (Publisher’s version ) (Closed access) The COVID-19 pandemic (and its aftermath) highlights a critical need to communicate health information effectively to the global public. Given that subtle differences in information framing can have meaningful effects on behavior, behavioral science research highlights a pressing question: Is it more effective to frame COVID-19 health messages in terms of potential losses (e.g., "If you do not practice these steps, you can endanger yourself and others") or potential gains (e.g., "If you practice these steps, you can protect yourself and others")? Collecting data in 48 languages from 15,929 participants in 84 countries, we…

2018

Introduction Introduction: eating disorders (ED) such as anorexia nervosa (AN) or bulimia nervosa (BN), as well as obesity (OB), are related to emotional and neuropsychological impairments on measures of cognitive flexibility, central coherence or decision making. However, little is known about the association among emotional regulation, neuropsychological variables and affect. Objectives: to analyze whether neuropsychological and affect variables can predict emotional regulation in ED and in OB. Methods: thirty females with restricting ED (restricting AN) were assessed, 18 with purging ED (purging AN and BN), 33 with OB and 39 healthy controls matched for intelligence. The Wisconsin Card S…
