In the last few decades, several works on cognitive processing during sleep have emerged. The study of cognitive processing with event related potentials (ERPs) during sleep is a topic of great interest, since ERPs allow the study of stimulation with passive paradigms (without conscious response or behavioural response), opening multiple research possibilities during different sleep phases. We review ERPs modulated by cognitive processes during sleep: N1, Mismatch Negativity (MMN), P2, P3, N400-like, N300-N550, among others. The review shows that there are different cognitive discriminations during sleep related to the frequency, intensity, duration, saliency, novelty, proportion of appearance, meaning, and even sentential integration of stimuli. The fascinating results of cognitive processing during sleep imply serious challenges for cognitive models. The studies of ERPs, together with techniques of neuroimaging, have demonstrated the existence of cognitive processing during sleep. A fundamental question to be considered is if these cognitive phenomena are similar to processing that occurs during wakefulness. Based on this question we discussed the existence of possible mechanisms associated with sleep, as well as the specific cognitive and neurophysiologic differences of wakefulness and sleep. Much knowledge is still required to even understand the conjunction of dramatic changes in cerebral dynamics and the occurrence of cognitive processes. We propose some insights based on ERPs research for further construction of theoretical models for integrating both cognitive processing and specific brain sleep dynamics. 相似文献

Annually, thousands of infant deaths are classified as sudden unexpected infant deaths (SUIDs). In an effort to reduce the risk of SUIDs, the American Academy of Pediatrics has made a number of recommendations to educate caregivers, childcare providers, and healthcare professionals on safe infant sleep practices. The purpose of the current study was to extend the literature on safe infant sleep practices by teaching caregivers to arrange safe infant sleep environments using a mannequin and common infant items. We partnered with community-based agencies to evaluate the effectiveness of behavioral skills training delivered in a single training session as part of the ongoing pre- or postnatal care these agencies provided. Following training, all participants demonstrated a substantial change in responding and returned favorable social validity ratings. We discuss these outcomes in light of previous studies, limitations, and future directions. 相似文献

This study aimed to understand how different mother-infant sleeping arrangements impact infants’ self-regulation, particularly their calming response. Thus this study investigated the effect of three prevalent mother-infant sleeping arrangements, co-sleeping (CS), sleeping beyond arm’s length from their mother (BAL), and solitary sleeping (SS), on infants’ physiological calming through self-regulation during a nap session in 24 infants (50% female, M = 1.85 months SD = 0.93 months), who were identified as either regular co-sleepers with their mothers, infants who slept in the BAL sleeping arrangement from their mother, and infants who are solitary sleepers (SS). The effect of all three sleeping conditions amongst all the three types of infants with different habitual sleeping arrangements was assessed. All infants spent 10 min (2 × 5 min sessions) in each sleeping condition (CS, BAL, SS) during which electrocardiographic recordings were collected to obtain interbeat intervals (IBI) and rMSSD, a measure of heart rate variability (HRV) an index of physiological calming, maintained by the parasympathetic pathway involved in self-regulation. Infants who regularly co-slept with their mothers had the highest IBI, indicating greater physiological calming and self-regulation across all sleeping arrangement conditions (CS, BAL, SS), followed by infants who regularly slept in the BAL sleeping arrangement from their mothers. IBI was lowest amongst regular solitary sleepers, potentially indicating physiological stress due to mother-infant separation. However, HRV indices during the sleeping arrangements (especially across regular solitary sleepers) were inconclusive as to whether the lack of change in HRV across all sleeping conditions was due to physiological stress responses or greater physiological regulation. This study is the first to investigate the effect of manipulated and habitual mother-infant sleeping arrangements on infant physiological calming. 相似文献

Background/ObjectiveCollaboRATE is a 3-item self-report measure of the patient experience of shared decision-making (SDM) process. The objective of this study is to assess the psychometric properties of CollaboRATE in community mental health care.MethodA cross-sectional study was conducted at a Community Mental Health Center of the Canary Islands Health Service. Two hundred and fifty consecutive psychiatric outpatients were invited to participate. Of those, 191 accepted (76.40% of response rate) and completed the CollaboRATE, the Control Preferences Scale (CPS), and a form with sociodemographic and clinical variables.ResultsExploratory factor analysis ratified the unidimensionality of the measure. High internal consistency was found (α Cronbach = .95, Guttman's λ = .93, and ω = .95). Strong positive correlations (p < .0001) were found between the CollaboRATE and the CPS. Only 39.80% of respondents gave the best possible score on CollaboRATE.ConclusionsThis study provides evidence for the reliability and validity of the Spanish version of the CollaboRATE as a measure of SDM. The measure is quick to complete and feasible for use in outpatient mental health care. At present, a significative number of psychiatric outpatients are not involved in SDM. The use of this measure in psychiatric routine care can be a key tool in assessing and implementing SDM. 相似文献
