Visuospatial attention lateralization in volleyball players and in rowers.

2011

In the present study, differences in visuospatial attention lateralization were evaluated in athletes engaged in open- compared to closed-skill sports and sedentary nonathletes. 23 volleyball players (open skill; Italian national level and regional level), 10 rowers (closed skill, Italian national level), and 23 sedentary participants responded to a computerized line-length judgment task. Five lines, differing in the length of their right and left segments, were randomly presented; the respondent made a forced-choice decision about the respective length of the two segments. Volleyball players responded significantly faster; those at the higher competitive level were also more accurate, mak…

Comparison of Foot and Hand Reaction Times among Men: A Methodologic Study Using Simple and Multiple-Choice Repeated Measurements

1995

The primary study goal was to compare visual simple and choice reaction times of the hand and foot to assess validity of measurements for evaluating subjects' ability to perform rapid, controlled movements. First, we examined the repeatability ( N = 34) for four different data-sampling methods from a series of 12 trials within sessions and between two test sessions. Simple and choice reaction times with the preferred hand and both feet were then compared among 153 healthy male volunteers aged 35 to 67 years. Pearson correlations for hand and ipsilateral and contralateral foot reaction times on simple and choice tasks (.53 to .80, p<.001) showed that psychomotor foot reaction time is a v…

Influence of Delay Period Duration on Inhibitory Processes for Response Preparation.

2015

In this study, we examined the dynamics of inhibitory preparatory processes, using a delayed response task in which a cue signaled a left or right index finger (Experiment 1) or hand (Experiment 2) movement in advance of an imperative signal. In Experiment 1, we varied the duration of the delay period (200, 500, and 900 ms). When transcranial magnetic stimulation (TMS) was applied 100 ms before the imperative, motor evoked potentials (MEPs) elicited in the first dorsal interosseous were strongly inhibited. For delays of 500 ms or longer, this inhibition was greater when the targeted muscle was selected compared with when it was not selected. In contrast, the magnitude of inhibition just aft…

Anticipatory effects of food exposure in women diagnosed with bulimia nervosa.

2002

Objective. To investigate cephalic phase responses (CPRs) in women diagnosed with bulimia nervosa and to test the assumption that eating disordered individuals respond with more marked CPRs and higher increases in psychophysiological arousal to the presentation of food cues. Method. Thirteen female inpatients diagnosed with bulimia nervosa were compared to 15 non-eating disordered female volunteers. Participants were exposed to their preferred binge food in a single laboratory session with the possibility to eat immediately after the exposure trial. Results. The results show greater salivation responses to food exposure and lower sympathetic arousal in patients diagnosed with bulimia nervos…

Breastfeeding initiation and duration in France: The importance of intergenerational and previous maternal breastfeeding experiences — results from t…

2019

International audience; OBJECTIVE: To assess the role of the mother's mother and mothers' previous personal experiences with breastfeeding and childcare in breastfeeding practices. DESIGN AND SETTING: The analysis included 13,774 mother-infant dyads from the French national birth cohort ELFE. Feeding practices were assessed by face-to-face interview in maternity wards in 2011, by phone interviews at months 2 and 12 post-partum and by Internet/paper questionnaires monthly from months 3-10. Sociodemographic, maternal and newborn-related factors were collected in the maternity unit and by postnatal phone interview at month 2. Multivariable logistic and linear regression was used to assess the …

An odor timer in milk? Synchrony in the odor of milk effluvium and neonatal chemosensation in the mouse.

2012

International audience; Mammalian newborns exhibit avid responsiveness to odor compounds emanating from conspecific milk. Milk is however developmentally heterogeneous in composition as a function of both evolved constraints and offspring demand. The present study aimed to verify whether milk odor attractivity for neonates is equally distributed along lactation in Mus musculus (Balb-c strain). Therefore, we exposed pups varying in age to milk samples collected from females in different lactational stages. The pups were assayed at postnatal days 2 (P2), 6 (P6) and 15 (P15) in a series of paired-choice tests opposing either murine milk and a blank (water), or two samples of milk collected in …

Color choice behavior in cats and the effect of changes in the color of the illuminant.

Personality and music preferences: the influence of personality traits on preferences regarding musical elements.

2005

The purpose of this scientific study was to determine how personality traits, as classified by Cattell, influence preferences regarding musical elements. The subject group consisted of 145 students, male and female, chosen at random from different Polish universities. For the purpose of determining their personality traits the participants completed the 16PF Questionnaire (Cattell, Saunders, & Stice, 1957; Russel & Karol, 1993), in its Polish adaptation by Choynowski (Nowakowska, 1970). The participants' musical preferences were determined by their completing a Questionnaire of Musical Preferences (specifically created for the purposes of this research), in which respondents indicated their…

Patients' readiness for dietary change at the beginning of counselling: a transtheoretical model-based assessment.

2003

Background  The purpose of this study was to explore patients' readiness for dietary change within a theoretical framework of the transtheoretical model. The patients were recently diagnosed to have type 2 diabetes or impaired glucose tolerance. We discuss the theoretical aspects of appropriate dietary counselling strategies from a standpoint of patient-specific stages of change. Methods  The data included 32 audiotaped diabetes counselling sessions with 16 patients conducted by two nurses. The transcribed data was analysed by using deductive content analysis. Results  The patients were at different stages of change of diabetes-affected dietary behaviour. Their stages of change varied in di…

Influence of substrate oxidation on the reward system, no role of dietary fibre.

2011

International audience; It has been suggested that a high intake of dietary fibre helps regulate energy intake and satiety. The present study aimed to examine whether dietary fibre influenced the liking and wanting components of the food reward system, the metabolic state or subsequent intake. Five sessions involving 32 normal-weight subjects (16 men and 16 women, 30.6 ± 7.6 year) were held. The sessions differed in the composition of the bread eaten during breakfasts (dietary fibre content varied from 2.4 to 12.8 g/100 g). Several factors such as the palatability, weight, volume, energy content and macronutrient composition of the breakfasts were adjusted. Energy expenditure, the respirato…
