Two Treatments for Fear of Flying Compared: Cognitive Behavioral Therapy Combined with Systematic Desensitization or Eye Movement Desensitization and…
2011
This study aimed to test a combined treatment with eye movement desensitization and reprocessing (EMDR) and cognitive behavioral therapy (CBT), compared with CBT integrated with systematic desensitization, in reducing fear of flying. Participants were patients with aerophobia, who were randomly assigned to two experimental groups in a before- and after-treatment research design. The Flight Anxiety Situations Questionnaire (FAS) and the Flight Anxiety Modality Questionnaire (FAM) were used. The efficacy of each program was evaluated comparing the pre- and post-treatment levels of fear of flying within subjects. A comparison of the post-treatment scores between subjects was also conducted. R…
Contrasting neurochemical and behavioral profiles reflects stress coping styles but not stress responsiveness in farmed gilthead seabream (Sparus aur…
2020
In fish, as well as in other vertebrates, contrasting suites of physiological and behavioral traits, or coping styles, are often shown in response to stressors. However, the magnitude of the response (i.e. stress responsiveness) has been suggested to be independent of stress coping style. One central neurotransmitter that has been associated with both stress responsiveness and differences in stress coping styles is serotonin (5-hydroxytryptamine, 5-HT). In this study, we investigated to what extent stress responsiveness reflects differences in stress coping, and the potential involvement of the 5-HT system in mediating such differences in farmed Gilthead seabream. Initially, fish were class…
Origin and Diet of the Prehistoric Hunter-Gatherers on the Mediterranean Island of Favignana (Ègadi Islands, Sicily)
2012
Hunter-gatherers living in Europe during the transition from the late Pleistocene to the Holocene intensified food acquisition by broadening the range of resources exploited to include marine taxa. However, little is known on the nature of this dietary change in the Mediterranean Basin. A key area to investigate this issue is the archipelago of the Ègadi Islands, most of which were connected to Sicily until the early Holocene. The site of Grotta d'Oriente, on the present-day island of Favignana, was occupied by hunter-gatherers when Postglacial environmental changes were taking place (14,000-7,500 cal BP). Here we present the results of AMS radiocarbon dating, palaeogenetic and isotopic ana…
Worker Personality and Its Association with Spatially Structured Division of Labor
2014
Division of labor is a defining characteristic of social insects and fundamental to their ecological success. Many of the numerous tasks essential for the survival of the colony must be performed at a specific location. Consequently, spatial organization is an integral aspect of division of labor. The mechanisms organizing the spatial distribution of workers, separating inside and outside workers without central control, is an essential, but so far neglected aspect of division of labor. In this study, we investigate the behavioral mechanisms governing the spatial distribution of individual workers and its physiological underpinning in the ant Myrmica rubra. By investigating worker personali…
Importance des récentes variations pluviométriques à Djibouti et besoins de quantification de leurs impacts
2014
Ces dernières décennies, l’Afrique de l’Est souffre d’une longue et lente détérioration pluviométrique. De 2007 à 2011, la ville de Djibouti a enregistré un déficit de 73% des précipitations moyennes annuelles par rapport à la moyenne de 30 ans (1981-2010). Pour caractériser la sécheresse actuelle, nous analysons une série pluviométrique reconstruite pour Djibouti-Ville de 1901 à 2013, les données de terrain permettant d’illustrer les impacts de ces variations pluviométriques. Les précipitations enregistrées à Djibouti ne présentent aucune tendance sur le long terme (1901-2013). Par contre, ces dernières années montrent une très grande variabilité: le suivi de la moyenne pluviométrique sur …
Interpersonal Circumplex Profiles Of Persistent Depression: Goals, Self-Efficacy, Problems, And Effects Of Group Therapy
2016
Objectives We assessed severely and persistently depressed patients’ interpersonal self-efficacy, problems, and goals, plus changes in interpersonal functioning and depression during 20 weeks of group therapy. Method Outpatients (32 female, 26 male, mean age = 45 years) completed interpersonal circumplex measures of goals, efficacy, and problems before completing 20 weeks of manualized group therapy, during which we regularly assessed depression and interpersonal style. Results Compared to normative samples, patients lacked interpersonal agency, including less self-efficacy for expressive/assertive actions; stronger motives to avoid conflict, scorn, and humiliation; and more problems with b…
Sensory preconditioning in newborn rabbits: from common to distinct odor memories.
2013
Brief Communication; International audience; This study evaluated whether olfactory preconditioning is functional in newborn rabbits and based on joined or independent memory of odorants. First, after exposure to odorants A+B, the conditioning of A led to high responsiveness to odorant B. Second, responsiveness to B persisted after amnesia of A. Third, preconditioning was also functional with two overlapping pairs of odorants (A+B and B+C) and amnesia of one odorant did not affect memory of the others. Thus, incidental pairing of odorants allows reinforcement of one odorant to implicitly reinforce the others, the bond then vanishes, and the memory of each element becomes independent.
HOW CBT (COGNITIVE BEHAVIORAL THERAPY) CAN MODULATE NEGATIVE EMOTIONAL FACTORS AS ANXIETY OR DEPRESSION IN OBESE PATIENTS
2013
Emotional factors have great influence on eating habits and increase the risk of obesity (1). Few studies demonstrate that patients affected by binge eating disorder felt negative emotions before overeatings; the main emotions reported were anxiety, then sadness and tiredness. Emotional eating is related to the stress (2,3), so when subjects feel anxiety and depression, is more probable that they use food as modulator of their emotions, in this way the weight develops fast with all risks of obesity. The obesity is often attended by a specific syndrome called metabolic syndrome; the main symptoms are insulin resistence, hyperinsulinemia, not-insulin-dependent diabetes mellitus, dyslipidemia,…
Does Attentional Style Moderate the Relationship between Time Perspective and Social Network Addiction? A Cross-Sectional Study on a Sample of Social…
2021
The present study investigates the role of attentional style as a moderator variable between temporal perspective and social network addiction, since little is known about users’ cognitive variables involved in this kind of addictive behavior. To achieve this goal, a sample of 186 volunteers and anonymous social networking sites users (M = 34%; F = 66%; Mage = 22.54 years; SD = 3.94; range: 18 ÷ 45 years) participated in a cross-sectional study. All participants filled out self-report instruments measuring temporal perspective, internal vs. external attentional style, and social network addiction. The results align with the previous literature and show that present fatalistic and past negat…
Cognitive rehabilitation of schizophrenia through NeuroVr training.
2013
Cognitive difficulties are prevalent in people with diagnosis of schizophrenia and are associated with poor long-term functioning. In particular, memory, selective, divided and sustained attention and executive functions are altered by this disease. We used a Virtual Reality environment (developed via the NeuroVr2.0 software) for the rehabilitation of shifting, sustained attention and action planning functions using tasks reminiscent of daily life tasks. Test and retest showed significant differences in the assessed cognitive dimensions.
