Objective

To describe an immobility reaction (IR) that was not previously reported at or immediately after birth in human newborns.

Method

We analyzed 31 videos of normal term vaginal deliveries recorded from Time 0 of birth defined as the as the moment that lies between the birth of the thorax and the pelvis of the infant. We searched for perinatal factors associated with newborn's IR.

Results

IR at birth was observed in 8 of the 31 newborns. The main features of their behavior were immobilization, frozen face, shallow breathing and bradycardia. One of the 8 newborns had sudden collapse 2 h after birth. We found significant relationships between maternal prenatal stress (PS) and IR (p = .037), and a close to significant one between infants’ lividness at Time 0 and IR (p = .053). The first breath of the 31 newborns occurred before and was not associated with the first cry (p < .001).

Discussion

The main features of IR at birth are similar to those of the universal most severe response to severe stress or danger. The relationship with PS suggests that children who had IR at birth might be at risk for similar disorders as those associated with PS. Sudden neonatal collapse of one of the IR newborns needs further research to determine if they are at risk for sudden infant death syndrome.

Conclusion

This first report of an IR reaction at birth in human infants could open up new paths for improving early neonatal care. Further research is needed for maternal PS, stress hormones, umbilical cord blood pH measurements in IR newborns. The challenge of education and support for parents of IR newborns is outlined.  相似文献

Two experiments were conducted to study effects of modality, temporal position, and their interaction on comparisons of successive stimuli. In Experiment 1, intramodal (tone–tone and line–line) and crossmodal (tone–line and line–tone) stimulus pairs, with two interstimulus intervals (ISIs), 400 and 2,000 ms, were presented. Participants indicated which stimulus was the “stronger.” Time-order errors (TOEs) were assessed using the D% measure and were found in all types of pairs. Variation in TOEs across conditions was well accounted for by changes in parameters (stimulus weights, reference levels) in an extended version of Hellström’s sensation weighting (SW) model. With an ISI of 2,000 ms, the first stimulus had a lower weight (less impact on the response) than did the second stimulus. More negative TOEs were found with the longer ISI in all pair types except tone–line. In Experiment 2, participants indicated which of two lines was the longer or which of two tones was the louder. An intra- or crossmodal anchor, or no anchor, was interpolated between the stimuli. Anchoring tended to reduce the weight of the first stimulus, suggesting interference with memory, and to yield negative TOEs. Intramodal anchors yielded reduced weights of both stimuli, most dramatically for tones, suggesting an additional effect of stimulus interference. Response times decreased with crossmodal anchors. For line–line pairs, strong negative TOEs were found. In both experiments, the variation in TOE across conditions was well accounted for by the SW model.  相似文献

The adverse social and physical conditions of homelessness pose significant developmental risks for children, which may be compounded or buffered by the quality of parenting behaviour they are exposed to. There is currently a limited understanding of how parents approach their care-giving role and responsibilities while adjusting to the experience of homelessness. Advancing knowledge in this area is essential for developing acceptable, appropriate and effective interventions to support highly marginalised and vulnerable homeless families. This review explored homeless parents’ perceptions of how homelessness affects their parenting behaviour and identified adaptive strategies that parents may use to mitigate the potentially negative impacts of homelessness on the quality of care-giving. A systematic search of four electronic databases (ASSIA, PsycINFO, Web of Science and MEDLINE) identified 13 published qualitative studies, all originating from the USA, which explored parenting behaviour in homeless contexts. The studies were critically appraised using the CASP qualitative assessment tool. Thematic synthesis identified the following determinants of parenting behaviour; negative self-concept in the parental role, parental mental health, material resources, challenges to autonomy and self-efficacy, daily hassles, physical environment and service context, stigma, child characteristics and lack of support. These were synthesised thematically using existing models of parenting determinants and positive parenting. Findings indicate substantive impacts of homelessness on parental mental health, parenting authority, material resources, parenting environments and social support. Parents developed a number of adaptive methods to negotiate the challenges of homeless parenting such as maintaining a positive mindset, cherishing the parental role and developing practical strategies. We conclude with recommendations that service providers should tailor parenting support to resource-constrained circumstances and that further research is required in order to better understand experiences of homeless parents in other international contexts.  相似文献

An initial study found that Deaf participants have a different definition of a date than the Traditional Sex Script (TSS). In the TSS, the man is viewed as the initiator who pushes for sex and the woman is expected to limit sex if they do not want to have intercourse; neither of these ideas were included in Deaf participants’ responses when asked what happens on a typical date. These findings may relate to early experiences in childhood. At an early age, hearing children are exposed to the TSS through popular culture. Deaf children are not exposed to these cues at the same level because of their lack of communication access. Here we compare Deaf college students to hearing college students to further investigate these issues using a more quantitative design.  相似文献

The ability to regulate emotions appropriately and effectively is important in maintaining positive social interactions and outcomes. The current study investigated the association between the habitual use of suppression and reappraisal, and involvement in bullying in high school. Other social outcomes, such as current social satisfaction and support, were also considered. Two hundred and nine first-year psychology university students (mean age 19.13 years, SD?=?1.523) completed online questionnaires. Results demonstrated that suppression was associated with greater retrospective reports of victimisation during high school and lower current social satisfaction and support, even when controlling for general affect. Reappraisal was mostly found to be unrelated to bullying and social outcomes, with only one association existing between higher reappraisal use and better social satisfaction, which was no longer significant when controlling for affect. The findings extend on previous research by demonstrating a negative association between suppression and involvement in bullying.  相似文献

We report normative data from a large (N = 307) sample of young adult participants tested with a computerized version of the long form of the classical Benton Facial Recognition Test (BFRT; Benton & Van Allen, 1968). The BFRT-c requires participants to match a target face photograph to either one or three of six face photographs presented simultaneously. We found that the percent accuracy on the BFRT-c (81%–83%) was below ceiling yet well above chance level, with little interindividual variance in this typical population sample, two important aspects of a sensitive clinical test. Although the split-half reliability on response accuracy was relatively low, due to the large variability in difficulty across items, the correct response times measured in this version—completed in 3 min, on average—provide a reliable and critical complementary measure of performance at individual unfamiliar-face matching. In line with previous observations from other measures, females outperformed male participants at the BFRT-c, especially for female faces. In general, performance was also lower following lighting changes than following head rotations, in line with previous studies that have emphasized participants’ limited ability to match pictures of unfamiliar faces with important variations in illumination. Overall, this normative data set supports the validity of the BFRT-c as a key component of a battery of tests to identify clinical impairments in individual face recognition, such as observed in acquired prosopagnosia. However, this analysis strongly recommends that researchers consider the full test results: Beyond global indexes of performance based on accuracy rates only, they should consider the time taken to match individual faces as well as the variability in performance across items.  相似文献

While there has been increasing interest in promoting father engagement in parenting interventions for child wellbeing, both research and practice endeavors have been hindered by a lack of a measure of father engagement practices. This paper reports the development and evaluation of a comprehensive, practitioner-report measure of father engagement practices–—the Father Engagement Questionnaire (FEQ). Practitioners (N?=?589; 84.5% females; mean age?=?38.56) involved in delivering parenting interventions in Australia completed the FEQ, along with background demographics and questions regarding their own and organization’s practice. A separate sample of 28 practitioners completed the FEQ twice, with a two-week interim, to assess test–retest stability of the measure. Exploratory factor analysis revealed five factors corresponding to the measure’s five intended content areas: Confidence in Working with Fathers, Competence in Using Engagement Strategies, Perceived Effectiveness of Engagement Strategies, Frequency of Strategy Use, and Organizational Practices for Father Engagement. Each of these scales demonstrated adequate internal consistency reliability and test–retest stability. As the five scales appear to be related but distinct, it is recommended that the FEQ is used as a multidimensional measure of father engagement. In terms of predictive validity, higher scores on the Confidence in Working with Fathers, Frequency of Strategy Use, and Organizational Practices for Father Engagement scales were associated with a higher likelihood of practitioner-reported father attendance. The results provide support for adequate psychometric properties of the FEQ as a research and clinical tool for assessing and monitoring father engagement practices.  相似文献

While the devastating effects of parental alcohol use on children’s health are well known, the specific impact of childbirth on parental alcohol consumption has rarely been examined in the general population. We sought to examine patterns of alcohol use associated with childbirth. Data were drawn from the US National Epidemiologic Survey on Alcohol and Related Conditions. We compared successively the characteristics of alcohol use among females living with a child under 1 year with (i) those of females not living with children under 1 year and (ii) those of females living with an older child. Mean daily ethanol intake was lower among females living with a child under 1 than among females either not living with children under 1 year (p?<?0.001) or living with an older child (p?<?0.01). Moreover, low-to-mild drinking frequencies fell among females living with a child under 1, compared with females either not living with children under 1 year (adjusted odds ratio (AOR)?=?0.56; 95% CI [0.40, 0.80] for at least once a month and AOR?=?0.40; 95% CI [0.27, 0.58] for less than once a month) or living with an older child (AOR?=?0.52; 95% CI [0.36, 0.75] for at least once a month and AOR?=?0.66, 95% CI [0.46, 0.94] for less than a month). No significant difference was found for males. Our study suggests that childbirth, as opposed to motherhood per se, reduces several (though not all) dimensions of alcohol consumption in females, but not in males.  相似文献

This study investigated infant predictors of early cognitive and emotional self-regulation from an intrinsic and caregiving environmental perspective. Sustained attention, reactive aspects of infant temperament, and maternal sensitivity were assessed at 10 months (= 124) and early self-regulation (including executive functions, EF, and emotion regulation) was assessed at 18 months. The results indicated that sustained attention predicted early EF, which provide empirical support for the hierarchical framework of EF development, advocating early attention as a foundation for the development of cognitive self-regulation. Maternal sensitivity and surgency predicted emotion regulation, in that infants of sensitive mothers showed more regulatory behaviours and a longer latency to distress, whereas high levels of surgency predicted low emotion regulation, suggesting both the caregiving environment and temperament as important in the development of self-regulation. Interaction effects suggested high sustained attention to be a protective factor for children of insensitive mothers, in relation to emotion regulation. In addition, high levels of maternal sensitivity seemed to foster development of emotion regulation among children with low to medium levels of sustained attention and/or surgency. In all, our findings point to the importance of both intrinsic and extrinsic factors in infant development of self-regulation.  相似文献

Previous behavioral and neurophysiological research has shown better memory for horizontal than for vertical locations. In these studies, participants navigated toward these locations. In the present study we investigated whether the orientation of the spatial plane per se was responsible for this difference. We thus had participants learn locations visually from a single perspective and retrieve them from multiple viewpoints. In three experiments, participants studied colored tags on a horizontally or vertically oriented board within a virtual room and recalled these locations with different layout orientations (Exp. 1) or from different room-based perspectives (Exps. 2 and 3). All experiments revealed evidence for equal recall performance in horizontal and vertical memory. In addition, the patterns for recall from different test orientations were rather similar. Consequently, our results suggest that memory is qualitatively similar for both vertical and horizontal two-dimensional locations, given that these locations are learned from a single viewpoint. Thus, prior differences in spatial memory may have originated from the structure of the space or the fact that participants navigated through it. Additionally, the strong performance advantages for perspective shifts (Exps. 2 and 3) relative to layout rotations (Exp. 1) suggest that configurational judgments are not only based on memory of the relations between target objects, but also encompass the relations between target objects and the surrounding room—for example, in the form of a memorized view.  相似文献
