Evidence for general cognitive ability (g ) in heterogeneous stock mice and an analysis of potential confounds
2002
The heterogeneous stock (HS) is a genetically outbred line of mice established more than 30 years ago from an 8-way cross of C57BL/6, BALB/c, RIII, AKR, DBA/2, I, A/J and C3H inbred mouse strains. The present study compared the performance of 40 HS mice across a battery of diverse cognitive tasks under a variety of motivations. Indices of emotionality were also included in order to assess their influence on performance. All measures of ability loaded positively on an unrotated first principal component that accounted for 31% of the variance, suggesting the presence of a common factor of general cognitive ability (g) underlying all tasks. A first factor derived from anxiety indices correlate…
On Incorporating Affective Support to an Intelligent Tutoring System: an Empirical Study
2018
Previous research studies have reported strong evidence that the emotional state of students may have a considerable impact on their learning. In this paper, we present an empirical study that evidences that it is possible to influence the user’s affective state in a controlled way, by adapting the system’s response. As part of this paper, we have analyzed the affective impact of varying the level of help provided in an existing Intelligent Tutoring System. Results show that it is possible to use classification approaches to predict positive and negative variations in dominance, valence, arousal, and performance to a reasonable level of accuracy.
Emotional arousal modulates the encoding of crime-related details and corresponding physiological responses in the Concealed Information Test
2011
Previous studies demonstrated that concealed crime-related memories can be validly identified using the Concealed Information Test (CIT). However, its field applicability is still debated, and it is specifically unknown how emotional arousal during a crime would influence CIT results. In the current study, emotional arousal during a mock crime and the time delay between mock crime and CIT examination were manipulated. At the immediate and the delayed CIT occasion, central crime details were better remembered than peripheral ones and enhanced emotional arousal further reduced memory for peripheral information. Electrodermal, respiratory, and cardiovascular responses to central crime details …
Domestic tourists’ experience in protected natural parks: A new trend in pandemic crisis?
2021
International audience; Since December 2019, the Covid-19 pandemic crisis has led to profound changes around the world with a lot of interdictions or constraints to travel outside one's own country. One of the major consequences has been the development of proximity tourism in outdoor spaces less conducive to the spread of the virus. From a study preceding this pandemic, this article seeks to better understand the experiences lived by domestic tourists when they visited protected natural parks in their country. Beyond the health risks, it analyses the dimensions and the influences of experiences lived in these parks by French domestic tourists (n = 500) using Pine and Gilmore's 4Es model (1…
An artistic approach to neurofeedback for emotion regulation
2019
AbstractNeurofeedback has been shown to be a promising tool for learning to regulate one’s own emotions in healthy populations and in neuropsychiatric disorders. While it has been suggested that neurofeedback performance improves when sensory feedback is related to the pathology under consideration, it is still difficult to represent in real time a proper feedback representative of our emotional state. Since emotion is a central part of people’s dealings with artworks, we have initiated a collaboration between neuroscientists and artists to develop a visual representation of emotions that can be used in neurofeedback experiences. As a result of this collaboration, emotions were represented …
LEVEL OF ACTIVATION AND GOAL-DIRECTED BEHAVIOUR: The effect of chlorpromazine on aggressive, achievement oriented, and affiliation oriented verbal re…
1963
The purpose was to investigate the effect of chlorpromazine on verbal response contents in sentence completion tests. 30 male subjects participated in two chlorpromazine and one placebo session. It was found that the amount of aggressive, achievement and affiliation oriented responses was significantly reduced as an effect of drug intake. The results are discussed on the basis of the theories of conflict motivation and of arousal.
Inventory record inaccuracy in supply chains: the role of workers' behavior
2014
Purpose – The purpose of this paper is to explore the effect of inventory record inaccuracy due to behavioral aspects of workers on the order and inventory variance amplification. Design/methodology/approach – The authors adopt a continuous-time analytical approach to describe the effect of inbound throughput on the inventory and order variance amplification due to the workload pressure and arousal of workers. The model is numerically solved through simulation and results are analyzed with statistical general linear model. Findings – Inventory management policies that usually dampen variance amplification are not effective when inaccuracy is generated due to workers’ behavioral aspects. Sp…

Arousal Styles during Public Speaking
2002
The nature of the public-speaking context as a physiologically arousing communication context is well-known. During public speaking, a significant increase in heart rate level above the baseline has been found in various studies. In these studies, arousal styles during speaking have generally been described on the basis of mean heart rates among a group of participants. Individual variation in HR responses has not received much attention. The purpose of the present study was to examine individual differences in heart rate responses during public speaking and to account for these differences in terms of particular explanatory variables. The heart rate curves of 47 speakers were examined one …
Verzögerte Identitätsentwicklung, Familienbeziehungen und Psychopathologie: Zusammenhänge bei gesunden und klinisch auffälligen Heranwachsenden
2018
Zusammenfassung. In einer vergleichenden Studie an gesunden Jugendlichen und jungen Erwachsenen sowie einer Gruppe von Patienten (gesamt N = 732) wurde die Identitätsentwicklung im Kontext von Identitätsstress, elterlichen dysfunktionalen Erziehungsstilen und Symptombelastung untersucht. Erwartungsgemäß fand sich in der Gruppe der Patienten eine arretierte Identitätsentwicklung mit hohen Werten in ruminativer Exploration, besonders viel Identitätsstress und eine hohe externalisierende und internalisierende Symptombelastung; die elterlichen Erziehungsstile waren durch viel mütterliche psychologische Kontrolle bei fehlender Unterstützung zusammen mit einer ängstlichen väterlichen Erziehung g…
