The detection efficiency of the clover Ge-detectors array at the RITU-GREAT facility
2015
Absolute detection efficiency depending upon its position along the beam line is determined for three germanium detectors, that are part of the GREAT spectrometer at the RITU separator focal plane. The efficiency is determined for an energy range from 80 keV to 1400 keV for all three detectors as an array and also individually using digital electronics. The optimal position for the detector array has been defined for two configurations of the GREAT spectrometer: with planar detector and without it. The obtained results have been compared with three references: a simulation prepared especially for this setup by another student, a previous study that was carried out by applying analogue elect…
Affective, Social, and Cognitive Outcomes During a 1-Year Wintering in Concordia
2016
International audience; This study investigated time patterns and the relationships between perceived stress, recovery, control, attention lapses, and defense mechanisms (DM) during a 12-month wintering in Concordia polar station with an international crew of 14 volunteers. This ICE (Isolated, Confined, Extreme) environment induced some stress, mainly in the social dimension and showed relationships (a) between DM and both stress and recovery and (b) between recovery and perceived control, highlighting the roles of DM and control in psychological adaptation. These results offer additional insights into the affective, social, and cognitive processes involved in adaptation. The findings sugge…
Voluntary Imitation in Alzheimer’s Disease Patients
2016
International audience; Although Alzheimer's disease (AD) primarily manifests as cognitive deficits, the implicit sensorimotor processes that underlie social interactions, such as automatic imitation, seem to be preserved in mild and moderate stages of the disease, as is the ability to communicate with other persons. Nevertheless, when AD patients face more challenging tasks, which do not rely on automatic processes but on explicit voluntary mechanisms and require the patient to pay attention to external events, the cognitive deficits resulting from the disease might negatively affect patients' behavior. The aim of the present study was to investigate whether voluntary motor imitation, i.e.…
Global Cognitive Functioning versus Controlled Functioning throughout the Stages of Development
2020
According to the All or None Hypothesis (Diamond, 2009), the cognitive system can operate in a global manner that is not very discriminate or in a more discriminate mode that demands greater precision, control, and cognitive effort. There are five corollaries to this hypothesis that describe, in an operative way, the conditions under which the controlled mode of functioning in the cognitive domain can be activated and thus tested. Given the impact this theory has generated and the absence of studies analyzing the corollaries in a collective and systematic way at different stages of development, this study was proposed, first of all, to test three of these corollaries in children, adolescent…
From Associations to Rules: Connectionist Models of Behavior and Cognition
2008
International audience; This book introduces a host of connectionist models of cognition and behavior. The major areas covered are high-level cognition, language, categorization and visual perception, and sensory and attentional processing. All of the articles cover unpublished research work. The key contribution of this book is that it focuses exclusively on the advances in connectionist modeling in psychology. The papers are relatively short, and were explicitly written to be accessible to both connectionist modelers and experimental psychologists.
Behavioral Restriction Determines Left Attentional Bias: Preliminary Evidences From COVID-19 Lockdown
2021
International audience; During the COVID-19 lockdown, individuals were forced to remain at home, hence severely limiting the interaction within environmental stimuli, reducing the cognitive load placed on spatial competences. The effects of the behavioral restriction on cognition have been little examined. The present study is aimed at analyzing the effects of lockdown on executive function prominently involved in adapting behavior to new environmental demands. We analyze non-verbal fluency abilities, as indirectly providing a measure of cognitive flexibility to react to spatial changes. Sixteen students (mean age 20.75; SD 1.34), evaluated before the start of the lockdown (T1) in a battery…
Correlation between Cognition and Balance among Middle-Aged and Older Adults Observed through a Tai Chi Intervention program
2020
Background: Age-associated decline in cognition and balance may cause severe ability loss for daily living activities among middle-aged and older adults. The relationship between cognition and balance in this aging population remains to be explored. Objective: The present study Is exploratory in nature and aimed to examine the relationship between balance (both static and dynamic components) and global cognitive function among middle-aged and older adults through Tai Chi (TC) practice as a research avenue. Methods: A short-term (12 weeks) intervention of TC was conducted among middle-aged and older adults in the community setting. Global cognitive function (using the Chinese version of the …
