Encephalon Mri in 4-12 Years Old Children: How Pain, Fear and Sadness Regulation Affect MRI Image Quality.

Magnetic Resonance Imaging is often difficult to conduct, especially in children, because of restricted space, forced immobility, and loud noises. Providing children with adequate and age-appropriate information about the procedurecould reduce the use of anesthesia, the time and cost necessary . This research investigated the emotional regulation skills of children when provided with an information and orientation task before the examination. Analogical scales were used to measure the levels of fear, pleasure, and pain felt by 60 children who were waiting for a brain magnetic Resonance in two hospitals in Milan . Data collection took place at three different junctures; upon children's arrival at the hospital, following their preparation for this experience, and after the examination. Results showed that preparing children for the procedure helped to reduce anxiety and provided a space for them to externalize and self-regulate their emotional experiences. To combine the information strategy with the lived experiences allows the patient to anticipate the examination and to experience it in a simulation context, thus coming to the real examination more prepared and less emotionally activated. Preparation has a positive effect on children of all ages, particularly 4- to 7-year-old's. Moreover, fear regulation is associated with improved Magnetic resonance quality.

The Editing Density of Moving Images Influences Viewers' Time Perception: The Mediating Role of Eye Movements.

The present study examined whether cinematographic editing density affects viewers' perception of time. As a second aim, based on embodied models that conceive time perception as strictly connected to the movement, we tested the hypothesis that the editing density of moving images also affects viewers' eye movements and that these later mediate the effect of editing density on viewers' temporal judgments. Seventy participants watched nine video clips edited by manipulating the number of cuts (slow- and fast-paced editing against a master shot, unedited condition). For each editing density, multiple video clips were created, representing three different kinds of routine actions. The participants' eye movements were recorded while watching the video, and the participants were asked to report duration judgments and subjective passage of time judgments after watching each clip. The results showed that participants subjectively perceived that time flew more while watching fast-paced edited videos than slow-paced or unedited videos; by contrast, concerning duration judgments, participants overestimated the duration of fast-paced videos compared to the master-shot videos. Both the slow- and the fast-paced editing generated shorter fixations than the master shot, and the fast-paced editing led to shorter fixations than the slow-paced editing. Finally, compared to the unedited condition, editing led to an overestimation of durations through increased eye mobility. These findings suggest that the editing density of moving images by increasing the number of cuts effectively altered viewers' experience of time and add further evidence to prior research showing that performed eye movement is associated with temporal judgments.

Cognitive Reserve and Driving-Related Cognitive Abilities in a Sample of Oldest Old Drivers Undergoing Assessment of Fitness to Drive.

This study examines the relationship between age, cognitive reserve (CR), and driving-related cognitive abilities in a sample of oldest old drivers undergoing evaluation of fitness to drive. Structural equation modeling was used to investigate the associations between age, CR, and performances to a standardized set of cognitive tests assessing fitness to drive. Education and work complexity were used as proxy measures of CR. The results showed both measures of CR, but not age, were significantly associated with higher general intelligence. Education also predicted higher decision speed, and decision speed partly mediated the effect of education on general intelligence. These findings suggest that over age of 80 years old, CR was a better predictor of driving-related cognitive abilities than age. Education was associated with better performance across different cognitive domains including processing speed.

The role of the dorsal striatum in the recognition of emotions expressed by voice in Parkinson's disease.

BACKGROUND AND PURPOSE: Non-motor impairment such as emotion recognition deficit in both facial and vocal expressions has been previously reported in Parkinson's disease (PD). We investigated whether the decoding of emotional prosody is impaired in PD and whether this deficit is related to striatal damage. METHODS: Fifteen PD patients and 15 healthy controls (HCs) were requested to listen to six audio tracks and to recognize the emotions expressed by a professional actor while reading a meaning-neutral sentence. All subjects also received a structural MRI examination. Volumetric measurements were extracted for the striatum, a key region involved in emotional processing and typically impaired in PD. RESULTS: Decoding sadness conveyed by voice was impaired in PD compared with HC and was related to the volume of the dorsal striatum bilaterally. CONCLUSIONS: The dorsal striatum is involved in the decoding of vocal negative emotions in PD.

Expressive Suppression Within Task-Oriented Dyads: The Moderating Role of Power.

Although research has so far consistently revealed that using suppression to regulate emotions has adverse personal and social effects, it has been argued that suppression may be less detrimental within non-close relationships. In the present work, we examined the effects of experimentally induced suppression on expressive behavior, emotional experience, and social outcomes within task-oriented interactions between individuals randomly assigned to high/low vs. equal power positions. Eighty-eight participants were randomly paired with a partner of the same gender (forty-four dyads). After being randomly assigned to one of four experimental conditions created to manipulate suppression use and power, each dyad was asked to complete two problem-solving tasks. The results showed that the participants who were assigned to the subordinate (low-power) role and who used suppression to regulate their emotions reported more negative emotional experience than did individuals assigned to equal-power roles, as well as more inauthenticity and diminished feelings of rapport compared to subordinates who freely expressed their feelings. Moreover, we found that the use of suppression also influenced participants assigned to the manager (high-power) role, as they exhibited less positive behavior, reported less positive experience and lower feelings of rapport when interacting with a partner asked to suppress. When individuals were assigned to equal power roles, the participants instructed to use suppression reported lower levels of positive emotions than did their partners as well as higher feelings of inauthenticity compared to uninstructed participants. Overall, these findings seem to suggest that suppression may impair task-oriented interactions between high/low power individuals more than interactions between individuals sharing equal power.

Effects of combined spinal-epidural analgesia on first stage of labor: a cohort study.

Background: Neuraxial anesthesia is considered as the gold standard in the control labor of pain. Its variants are epidural analgesia and combined spinal-epidural analgesia. Few studies, as yet, have investigated the duration of labor as a primary outcome. Some authors have suggested that combined spinal-epidural analgesia may reduce labor duration but at the moment the benefit of shortening labor is uncertain. The main aim of this study was to compare combined spinal-epidural with epidural analgesia in terms of their effect on duration of stage I labor, maternal, and neonatal outcomes. Methods: A prospective cohort study was conducted. Parturients who requested analgesia at cervical dilatation <6 cm were included. Analgesia was either epidural with low concentration levobupivacaine or combined spinal epidural with subarachnoid sufentanil. The primary outcome was the length of stage I labor. Onset and quality of analgesia, mode of delivery, effects on uterine activity and use of oxytocin, fetal heart rate abnormalities and uterine hyperkinesia, maternal, and neonatal complications were also considered. Results: We enrolled 400 patients: 176 in the combined spinal-epidural group and 224 in the epidural group. Patients in the two treatment groups were similar with regard to demographic characteristics, parity, and incidence of obstetric comorbidities, labor induction, oxytocin infusion, Bishop score, and Visual Analogue Score (VAS) at analgesia request. Duration of stage I labor did not differ, at 195 (120-300) minutes for both the groups (p = .7). Combined spinal-epidural was associated with less reduction in uterine contractility after initial administration: 15.34 versus 39.73%, (p < .001) and with delayed need for oxytocin, at dilations of 7 ± 2.5 cm versus 6. ± 2.7, (p = .002). Onset of analgesia was quicker for combined spinal-epidural analgesia: 31 versus 20%, with VAS <4 after 5 minutes, (p < .001); and lower VAS scores after initial analgesia administration. No differences were found in the other outcomes. Conclusions: Combined spinal-epidural with subarachnoid sufentanil may not reduce the duration of stage I labor, but in our study it appeared to affect uterine contractility less. It also had a more rapid onset and was more effective, without any concomitant increase in maternal or neonatal complications.

The coconstruction of interpersonal recognition in the clinical dialogue of the diagnostic process: A multilevel analysis of the verbal content and vocal nonverbal dimension.

The present study is an empirical evaluation of a clinical setting from a particular point of view, able to integrate the vocal dimension-used in different fields of psychology as an indicator of rational phenomena-with the linguistic dimension of contents. Starting from the "interpersonal recognition" extracted from the contents of the verbatim transcripts of some diagnostic processes using the Strumento di Valutazione del Riconoscimento Interpersonale (Evaluation Tool for Interpersonal Recognition), the variation of vocal parameters both in the clinician and in the patient were analyzed. The goal consists in identifying possible nonverbal vocal micro indicators used in the dyadic process of interpersonal recognition. Specific and bidimensional nonverbal vocal patterns and strategies are hypothetically matched with different efficacy levels of recognition, both for the clinician and the patient.

Outcomes of induced versus spontaneous labor.

PURPOSE: Induced labor is associated with a higher request for analgesia than spontaneous labor. This study compared duration of labor, mode of delivery, quantity of blood loss, type of perineal outcome and neonatal outcomes between women in induced labor and women in spontaneous labor, both on epidural analgesia (administered at cervical dilation ≤ 4 cm). METHODS: In a two-year longitudinal cohort study, data were gathered from nulliparous women with a single cephalic pregnancy of at least 37 weeks attending the labor and delivery ward in Policlinico San Matteo Fundation-Pavia. Data were compared for women with early labor analgesia in (1) spontaneous labor (Robson group 1) and (2) induced labor (dinoprostone - vaginal insert or gel, Robson group 2a). RESULTS: Of the 1104 women who underwent epidural analgesia in the study period, 531 were included: 326 in spontaneous labor and 205 in induced labor. The only significant difference found was duration of the first stage, which lasted 305 (200-390) min in spontaneous labor compared to 205 min (120-345) in induced labor (p <0.001). CONCLUSIONS: In women on early epidural analgesia, induction is associated with a shorter duration of the first stage of labor and does not affect other outcomes.

More Than Defense in Daily Experience of Privacy: The Functions of Privacy in Digital and Physical Environments.

The purpose of the current study was to investigate the experience of privacy, focusing on its functional role in personal well-being. A sample (N = 180) comprised subjects between 18 and 50 years of age were asked to spontaneously provide accounts of their experiences with privacy and answer close-ended questions to acquire a description of a daily experience of privacy. The results showed the importance attributed to the function of privacy related to the "defense from social threats", and the twofold function of privacy related to an "achieved state of privacy", in the terms of both "system maintenance" and "system development". The results also shed light on the role of the environment in shaping one's experience of privacy. Specifically, the participants recognized more easily the function of defense from threats related to seeking privacy while interacting in digital environments, whereas they seemed to benefit from positive functions related to an achieved state of privacy in physical environments. The findings sustain the notion of privacy as a supportive condition for some psychological processes involved in the positive human functioning and confirm previous studies conducted on the role of privacy in human well-being.

How does a collision warning system shape driver's brake response time? The influence of expectancy and automation complacency on real-life emergency braking.

Brake Reaction Time (BRT) is an important parameter for road safety. Previous research has shown that drivers' expectations can impact RT when facing hazardous situations, but driving with advanced driver assistance systems, can change the way BRT are considered. The interaction with a collision warning system can help faster more efficient responses, but at the same time can require a monitoring task and evaluation process that may lead to automation complacency. The aims of the present study are to test in a real-life setting whether automation compliancy can be generated by a collision warning system and what component of expectancy can impact the different tasks involved in an assisted BRT process. More specifically four component of expectancy were investigated: presence/absence of anticipatory information, previous direct experience, reliability of the device, and predictability of the hazard determined by repeated use of the warning system. Results supply indication on perception time and mental elaboration of the collision warning system alerts. In particular reliable warning quickened the decision making process, misleading warnings generated automation complacency slowing visual search for hazard detection, lack of directed experienced slowed the overall response while unexpected failure of the device lead to inattentional blindness and potential pseudo-accidents with surprise obstacle intrusion.
