Preterm birth affects dorsal-stream functioning even after age 6

With increasing numbers of preterm infants surviving, the impact of preterm birth on later cognitive development presents a major interest. This study investigates the impact of preterm birth on later dorsal- and ventral-stream functioning. An atypical pattern of performance was found for preterm children relative to full-term controls, but in the dorsal-drawing task only. These findings suggest that the number of gestational weeks does affect dorsal-stream functioning, even after more than 6 years of favorable environmental conditions in healthy preterm children.     

Preterm infant body composition,working memory,and temperament

Altered body composition in preterm infants is associated with risks to cognitive development, but the effect specific to prefrontal cortex (PFC) development is unknown. We were interested in the impact of fat mass (FM) and fat free mass (FFM) gains out to 4 months corrected gestational age (CGA) on PFC development, as indexed by working memory and temperament. This is a prospective observational pilot study recruiting 100 preterm (<33 weeks gestation), appropriate for gestational age, and very low birth weight infants, of which 49 infants met inclusion criteria. Body composition was measured using air displacement plethysmography at hospital discharge and 4 months CGA. Questionnaire based temperament assessments were completed at 12 and 24 months CGA and a working memory assessment was completed at 24 months CGA. Associations between developmental tests and body composition obtained at term and 4 months were analyzed. Increased FM at discharge was associated with increased fear and decreased soothability at 12 months. Increased FM at 4 months was associated with increased activity level, increased distress from limitations at 12 months and decreased attentional shifting, decreased frustration, and decreased inhibitory control at 24 months. Increased FFM at 4 months was associated with increased activity level at 12 months and increased impulsivity and decreased low intensity pleasure at 24 months. In this exploratory pilot study, increased FM out to 4 months and increased FFM after discharge are associated with negative markers of infant temperament. Infant temperament may be sensitive to body composition status at least to 4 months CGA.     

Preterm infants show reduced stress behaviors and activity after 5 days of massage therapy

Preterm infants residing in an NICU were randomly assigned to a massage therapy or to a control group. The preterm infants in the massage therapy group received three 15-min massages each day for 5 consecutive days, with the massages consisting of moderate pressure stroking to the head, shoulders, back, arms and legs and kinesthetic exercises consisting of flexion and extension of the limbs. Infant stress behaviors and activity were recorded on the first and last day of the study. Preterm infants receiving massage therapy showed fewer stress behaviors and less activity from the first to the last day of the study. The findings suggest that massage has pacifying or stress reducing effects on preterm infants, which is noteworthy given that they experience numerous stressors during their hospitalization.     

Preterm birth and maternal sensitivity: Findings from a non-western country

IntroductionAlthough there are several studies on maternal sensitivity of preterm-born children conducted in Western countries, the factors affecting the sensitivity of mothers of preterm infants have not been investigated outside the Western context.ObjectivesThis study aimed to compare maternal sensitivity of preterm children at 18 months of corrected age with their healthy term-born peers and explore the factors associated with maternal sensitivity in a middle-income non-Western country. Moreover, the associations of maternal sensitivity with socio-demographic factors, maternal depression, and social-emotional competency and behavior problems of infants were investigated.MethodsIn total, 70 (40 preterm-born and 30 term-born) mother-child dyads participated in this study. An observation-based measurement tool, Maternal Sensitivity Scale, was used to assess maternal sensitivity. Social-emotional competency and behavior problems of infants were evaluated via The Turkish version of the Brief Infant-Toddler Social Emotional Assessment. Maternal depressive symptoms were assessed via the Beck Depression Inventory. In addition, a demographic information form was filled out by the mothers.ResultsMaternal sensitivity scores of preterm infants were significantly lower compared to term infants. Depressive symptoms scores and employment status of mothers, socio-economic status (SES), gestational age, breastfeeding duration, and behavior problems of children were the factors related to maternal sensitivity scores. In hierarchical regression analysis, SES and gestational age were the strongest predictors of maternal sensitivity. After controlling SES and gestational age, maternal depressive symptoms scores negatively predicted maternal sensitivity scores.ConclusionThis study pointed out the factors associated with the maternal sensitivity of preterm infants outside the Western context. Interventions to improve sensitive parenting behaviors of preterm infants are needed, especially in socio-economically disadvantaged groups.     

The utilization of genetic counselors within a newborn screening program

Genetic counselors have participated in the Michigan Newborn Screening Program on a contractual basis since 1988. Their role includes newborn screening education and training, newborn nursery site visits, and monitoring newborn screening in hospitals. Their impact has been to improve the quality of newborn screening services by reducing errors and increasing completion of data fields on newborn screening cards, improving hospital nursery cooperation and problem solving, and enhancing health department response to specific problems.     

Crossmodal learning in newborn infants: Inferences about properties of auditory-visual events

The majority of research on infant crossmodal perception has addressed the question of whether infants 4 months and older demonstrate the ability. By contrast, the focus in the present study was on newborns and the primary goal was twofold: to determine if newborns can learn arbitrary sight-sound pairings and to evaluate possible inferences that neonates make when repeatedly presented arbitrary sight-sound pairings. Alert neonates were familiarized with toy-sound pairs using an infant-controlled habituation procedure. They were then given a violation-of-expectancy test to determine if they had learned these sight-sound pairings and drawn any inferences about certain properties of these bimodal events. Results supported the conclusion that infants just a few hours old can learn sight-sound pairings. Furthermore, the findings suggested that newborns expected sight-sound pairs to remain colocated even when they move to a new location, they recognized that the sound was an attribute of a specific object, and they recognized that a specific spatial location was not an attribute of the sight-sound pair. Thus, infants made important and correct inferences based on limited experiences with specific auditory-visual events, and they did so just after birth. Implications of these findings for theories of crossmodal perceptual development are discussed.     

Hierarchical organization of a reference system in newborn spontaneous movements

In this paper, we studied spontaneous newborn movements regarding the coordination of the four limbs, arms and legs, from a dynamic perspective. We used the method of recurrence plots to analyse the kinematic data from audiovisual recordings of neonates. We identified temporal and spatial synchronization of the four limbs that resulted in high recurrence patterns of biomechanical reference configurations. Furthermore, we identified transitions between linear and nonlinear epochs in the movement behavior of newborns on different time scales by means of recurrence quantification analysis. Results are discussed in the context of the concept of a structural hierarchy, in which different time scales correspond to hierarchical levels of organization.     

The effect of odors on human newborn infants under stress

Five-day-old human infants' responses to heelstick stress were assessed with behavioral and physiological indices. The subjects were divided randomly into three groups: the LAV group, who were presented with artificial odor of lavender during the heelstick; the MILK group, who were presented with artificial odor of milk during the heelstick; and the CONT group, who were presented with no special odors. The CONT group showed more adrenocortisol release in saliva than the other groups, but there were no differences between the two odors.     

Personnel selection in the digital age: a review of validity and applicant reactions,and future research challenges

ABSTRACT

We present a targeted review of recent developments and advances in digital selection procedures (DSPs) with particular attention to advances in internet-based techniques. By reviewing the emergence of DSPs in selection research and practice, we highlight five main categories of methods (online applications, online psychometric testing, digital interviews, gamified assessment and social media). We discuss the evidence base for each of these DSP groups, focusing on construct and criterion validity, and applicant reactions to their use in organizations. Based on the findings of our review, we present a critique of the evidence base for DSPs in industrial, work and organizational psychology and set out an agenda for advancing research. We identify pressing gaps in our understanding of DSPs, and ten key questions to be answered. Given that DSPs are likely to depart further from traditional non-digital selection procedures in the future, a theme in this agenda is the need to establish a distinct and specific literature on DSPs, and to do so at a pace that reflects the speed of the underlying technological advancement. In concluding, we, therefore, issue a call to action for selection researchers in work and organizational psychology to commence a new and rigorous multidisciplinary programme of scientific study of DSPs.     

Implications of research for the treatment of depressive disorders during childhood

Basic research into the prevalence, natural course, and phenomena of comorbidity of depressive disorders during childhood are reviewed and implications of this research for treating depressed youths are noted. Results of investigations into the biological aspects of depression are integrated into a multifactorial model of depressive disorders during childhood and the efficacy of pharmacological interventions is discussed. Cognitive theory is integrated with attachment theory to explain a possible avenue to the development of depressive disorders during childhood. Interpersonal therapy has emerged as a potentially effective intervention for depressed youths. Basic tenets of this treatment model are compared and contrasted to a cognitive-behavioral treatment model, and a hybrid treatment referred to as “cognitive therapy within the interpersonal context” is proposed.     

Chronic pelvic pain: A meta-analytic review

Abstract

Chronic pelvic pain (CPP) in women of reproductive age is a common complaint; for many women no identifiable pathology can be found. Research has suggested that women who have chronic pelvic pain without obvious pathology differ on a range of psychological characteristics, such as anxiety and depression, compared with those with identified pathology. A meta-analysis of 22 studies was undertaken to clarify these issues. Results showed that there were no significant differences on a range of psychological variables between women who were identified, via laparoscopy and clinical judgement, as having organic disorders and those who were not so identified. When women with chronic pelvic pain were compared with pain-free groups a profile of elevated depression, anxiety, neuroticism and psychopathology was found which is consistent with findings from studies of other painful conditions.     

Understanding the role of gender in body image research settings: Participant gender preferences for researchers and co-participants in interviews,focus groups and interventions

Participant gender preferences for body image researchers, interventionists and focus group and intervention co-participants have been largely ignored, despite recognition that such characteristics can influence the nature and quality of data collected and intervention effects. To address this, Australian women (n = 505) and men (n = 220) completed a questionnaire about their preferences for interviewers and focus group facilitators, for teachers delivering school-based interventions, and for co-participants in these settings. Women predominantly preferred female interviewers and teachers, and mixed-sex co-participants, but most had no preference for focus group facilitators. Body dissatisfied women were more likely to prefer female researchers and single-sex co-participants. Most men did not have specific preferences, however, body dissatisfied men were more likely to report a gender preference for interviewers and teachers. Professional capabilities, personal qualities and appearance were regarded as important researcher characteristics. These findings have important implications for body image research, particularly among high-risk groups.     

Free-time as a consequence for behavior in classroom settings: A critical review

Osborne (1969) presented adolescent hearing impaired students with five minutes of free- time contingent upon remaining seated for 15 minutes in the classroom. This procedure substantially reduced the frequency of out- of- seat behavior. Since the publication of this seminal work, 49 studies have used free- time as a consequence to change behavior. This review critically examines these 49 studies. The review shows that free-time has been used effectively with a variety of different behaviors and student populations, and with different methods of delivery. Based on a synthesis of information from the review, optimal methods for the use of free-time are suggested. Finally, it is concluded that additional research is needed, especially to answer the question of why free-time is effective.     

A review of competitive sport motivation research

ObjectivesThe purpose of this review was to synthesise contemporary research on competitive sport motivation (1995–2016) with a view to identifying trends and gaps in sample characteristics, research designs and analytical strategies, and classifying associated topics.DesignNarrative review.MethodFour databases were searched using a focused search strategy, leading to 63 studies that met the inclusion criteria. These were then evaluated in five sections: Theoretical Frameworks, Sample Characteristics, Research Designs, Analytical Strategies and Topics.ResultsA total of 63 studies comprising 12,440 participants were appraised. The average sample size and participant age were 197 and 22.6 years, respectively. Just over half of the studies described their sample as high-level. The majority of studies were quantitative and employed a cross-sectional design. A range of innovative statistical analyses were used, with structural equation modelling being increasingly adopted. In addition to studies focusing on motivation as a stand-alone topic, researchers in the area also investigated its relationship with motivational climate, burnout, doping, perfectionism, injury, and several other related variables.ConclusionsAfter reviewing the body of research on this specific topic area, promising directions for future research are presented. The focused approach particularly seeks to encourage researchers to employ different methodologies, and prioritise underused topics in future research on competitive athlete groups. Furthermore, the review points to several practical implications for competitive sport stakeholders.     

A methodological review of preference displacement research

The purpose of this review was to identify and compare methodological components of preference displacement research and outcomes. We coded, categorized, and defined patterns of preference displacement for a total of 133 participants across 10 studies. We found that patterns of displacement differed within and across studies, and over 46% of participants did not engage in patterns of displacement. Therefore, the commonly held notion that edible stimuli are more likely to displace tangible stimuli is not as ubiquitous as once thought. However, due to considerable variation in methodology and reporting across reviewed studies, it is difficult to determine what variables may be responsible for obtained study outcomes. We conclude that future researchers consider the importance of each methodological variable coded in our review, and make methodological decisions in the context of the research question they are looking to answer. We also provide additional suggestions for future research and clinical practice.

The state of mentoring research: A qualitative review of current research methods and future research implications

Research regarding mentoring relationships has flourished during the past 20 years. This article reviews the methodology and content of 200 published mentoring articles. Some of the major concerns raised in this review include over reliance on cross-sectional designs and self-report data, a failure to differentiate between different forms of mentoring (e.g., formal versus informal), and a lack of experimental research. Implications and suggestions for future research are offered.
