Auditory cortical and hippocampal-system mismatch responses to duration deviants in urethane-anesthetized rats.
2013
Any change in the invariant aspects of the auditory environment is of potential importance. The human brain preattentively or automatically detects such changes. The mismatch negativity (MMN) of event-related potentials (ERPs) reflects this initial stage of auditory change detection. The origin of MMN is held to be cortical. The hippocampus is associated with a later generated P3a of ERPs reflecting involuntarily attention switches towards auditory changes that are high in magnitude. The evidence for this cortico-hippocampal dichotomy is scarce, however. To shed further light on this issue, auditory cortical and hippocampal-system (CA1, dentate gyrus, subiculum) local-field potentials were …
Smart Phone, Smart Science: How the Use of Smartphones Can Revolutionize Research in Cognitive Science
2011
WOS:000295936900019; International audience; Investigating human cognitive faculties such as language, attention, and memory most often relies on testing small and homogeneous groups of volunteers coming to research facilities where they are asked to participate in behavioral experiments. We show that this limitation and sampling bias can be overcome by using smartphone technology to collect data in cognitive science experiments from thousands of subjects from all over the world. This mass coordinated use of smartphones creates a novel and powerful scientific "instrument" that yields the data necessary to test universal theories of cognition. This increase in power represents a potential re…
How Journalists Think about Media Effects—And Why We Should Care
2019
Research suggests that journalists’ beliefs about media effects are influenced by unsystematically gathered knowledge and subjective-intuitive judgments. However, it has also been shown that these presumptions must be considered important factors for the formation of journalistic coverage. Against this background, this article synthesizes existing research on dimensions, determinants, and consequences of journalists’ presumptions of media effects. The resulting framework offers researchers in the field of journalistic content production a comprehensive overview of the possible role that presumptions of media effects could play for journalistic content creation. In a second step, we summariz…
Tracking the Emergence of the Consonant Bias in Visual-Word Recognition: Evidence with Developing Readers
2014
Recent research with skilled adult readers has consistently revealed an advantage of consonants over vowels in visual-word recognition (i.e., the so-called "consonant bias"). Nevertheless, little is known about how early in development the consonant bias emerges. This work aims to address this issue by studying the relative contribution of consonants and vowels at the early stages of visual-word recognition in developing readers (2(nd) and 4(th) Grade children) and skilled adult readers (college students) using a masked priming lexical decision task. Target words starting either with a consonant or a vowel were preceded by a briefly presented masked prime (50 ms) that could be the same as t…
How and when do mobile media demands impact well-being? Explicating the integrative model of mobile media use and need experiences (IM3UNE)
2021
Using mobile media can be both detrimental and beneficial for well-being. Thus, explaining how and when they elicit such effects is of crucial importance. To explicate boundary conditions and processes for digital well-being, this article introduces the Integrative Model of Mobile Media Use and Need Experiences (IM³UNE). Instead of assuming mobile media to be pathogenic, the IM³UNE offers a salutogenic perspective—it focuses on how we can stay healthy when using mobile media ubiquitously in daily life. More specifically, the model assumes that both the satisfaction and the frustration of basic psychological needs are key underlying mechanisms linking demanding mobile media use to well-being…
Testosterone and cortisol release among Spanish soccer fans watching the 2010 World Cup Final
2012
This field study investigated the release of testosterone and cortisol of a vicarious winning experience in Spanish fans watching the finals between Spain and the Netherlands in the 2010 FIFA World Cup Soccer. Spanish fans (n = 50) watched the match with friends or family in a public place or at home and also participated in a control condition. Consistent with hypotheses, results revealed that testosterone and cortisol levels were higher when watching the match than on a control day. However, neither testosterone nor cortisol levels increased after the victory of the Spanish team. Moreover, the increase in testosterone secretion was not related to participants' sex, age or soccer fandom, b…
Lifestyle counseling to reduce body weight and cardiometabolic risk factors among truck and bus drivers – a randomized controlled trial
2015
Objectives We conducted a randomized trial among overweight long-distance drivers to study the effects of structured lifestyle counseling on body weight and cardiometabolic risk factors. Methods Men with waist circumference > 100 cm were randomized into a lifestyle counseling (LIFE, N=55) and a reference (REF, N=58) group. The LIFE group participated in monthly counseling on nutrition, physical activity, and sleep for 12 months aiming at 10% weight loss. After 12 months, the REF group participated in 3-month counseling. Assessments took place at 0, 12, and 24 months. Between-group differences in changes were analyzed by generalized linear modeling. Metabolic risk (Z score) was calculated fr…
The Challenges Underlying Firm Revival and Resilience in the Post-COVID-19 Phase
2022
Covid-19 is an exogenous shock that has deeply modified the basic building blocks and the micro-mechanisms on which socio-economic systems and organizations rest. The vast majority of both factor markets and final markets have been significantly disrupted on a worldwide scale. As all factors that determine severe crises, the Covid-19 pandemic is a low probability and high impact shock which has significantly changed the environment in which firms operate (Grewal and Tansuhaj 2001, Hudecheck et al. 2020). Such changes have nonetheless been asymmetric, whilst they have menaced the survival of a huge number of firms and have brought to their knees many key industries, it has also ignited rapid…
SOCIOLOGIA DELLA DEVIANZA E DEL CRIMINE. Prospettive, ambiti e sviluppi contemporanei
2021
Il manuale che presentiamo nasce con l’intento di aggiornare e ravvivare il dibattito critico sul discorso socio-criminologico, cercando di colmare un vuoto esistente nel mercato editoriale italiano riguardo alle prospettive e agli sviluppi contemporanei delle teorie sociologiche della devianza e del crimine. Uno dei pregi del volume è l’essere il frutto di un lavoro corale che ha coinvolto studiose e studiosi italiani intenti a elaborare, ciascuno in base alle proprie specializzazioni, riflessioni e analisi su temi e teorie socio-criminologiche alla luce dei più recenti sviluppi contemporanei. L’impostazione pluralista consente una visione polifonica senza perdere di vista il filo condutto…
