Video Versus Reality: Infants' Attention and Affective Responses to Video and Live Presentations

Television viewing by infants has become very common, yet relatively little is known about infants' reactions to video compared to live events. We conducted two experiments in order to compare 9- or 10-month-old infants' behavioral reactions to live events and video presentations of those events. In the first experiment, infants' were shown video and live presentations shown consecutively; their affective reactions were consistent, indicating that video conveys meaning and emotional impact even in infancy. However, infants generally looked longer at, reached more to, showed more interest in, and exhibited more fear to the real stimuli. In a second experiment, infants were shown identical live and video events simultaneously; they looked much longer at the live presentations, further confirming that they distinguished live events from video and preferred to watch real events. Implications for infants' television viewing and the use of video images in infancy research are discussed.     

Early childhood co-sleeping: Parent-child and parent-infant nighttime interactions

This study investigated parent—child interactions during sleep onset and nighttime arousals in a rural sample of preschool children. The role of co-sleeping in relation to sleep habits and night waking was examined using parental self-report of both current and retrospective sleep patterns. The results showed that Solitary Sleepers engaged in more complex bedtime routines, and had more longstanding and stronger attachment to security objects and sleep aids, than did Co-sleepers. Infancy precursors to co-sleeping in early childhood were a history of breastfeeding, night feedings in the parent's bed, and returning to sleep in the parent's bed.

A Playroom Observation Procedure to Assess Children with Mental Retardation and ADHD

Forty-two children (ages 6 to 12 years old) with moderate mental retardation to borderline intellectual functioning were studied in a laboratory playroom setting to determine whether children identified as ADHD (attention deficit hyperactivity disorder) or controls differed on activity and attentional measures. Children with ADHD were further divided into ADHD + conduct problems (ADHD + CD) and ADHD-only subgroups (with an ADHD-combined group comprising children of both subgroups). An interval recording system was used to code observations of independent play and a restricted academic task. Results indicated that the ADHD-combined group was significantly more vocal and engaged in a significantly greater number of toy changes than controls during independent play. Significant group differences were also noted during the restricted academic task, with the ADHD-combined and ADHD + CD groups more off-task and engaging in a greater number of toy touches than controls. Discriminant analyses found independent play measures to predict group membership in 70 percent of cases (ADHD-combined vs. controls), but in only 64 percent of cases using measures from the restricted academic task. No significant findings resulted when the ADHD subjects were further divided into two subgroups. Despite some inconsistent findings, such laboratory-based observations may be of value in the diagnosis of ADHD in children with moderate mental retardation to borderline intellectual functioning.     

Analysis of Live Modeling Plus Prompting and Video Modeling for Teaching Imitation to Children with Autism

Previous researchers have demonstrated that training in imitation can significantly improve the learning capabilities of children diagnosed with autism spectrum disorder (ASD) and that children within this population show a preference for video presentations. Video‐based instruction has been used to teach a variety of behaviors to individuals with ASD. However, only a small number of studies have examined the use of video modeling to teach initial imitation. Furthermore, there are limited and conflicting data on the effectiveness of a video modeling procedure that does not incorporate prompting when used to teach imitation to young children with ASD. Thus, the purpose of this study was to evaluate a video‐modeling‐alone procedure and a live‐modeling‐with‐prompting procedure for teaching imitation to young children with ASD. The results suggest that the live modeling with prompting procedure was more effective, and implications related to this finding are discussed. Copyright © 2015 John Wiley & Sons, Ltd.     

亲子三角关系的性别差异

亲子三角关系指父母发生冲突时,子女主动或被动卷入其中而形成的不平衡的“父亲—子女—母亲”三角关系,通常包括代罪羔羊、亲职化和跨代联盟三大类型,与儿童青少年的内外化行为问题等密切关联。在有关亲子三角关系的发生特点及其影响是否具有性别一致性的问题上,既有研究结论尚存在分歧。这可能与人口学变量的差异和性别角色观念的变迁等因素有关。国内大陆在该领域的研究近乎为零。未来需通过开展本土研究,细化人口学变量和综合运用多种测量方法与指标,采用追踪设计等厘清该问题。     

Parental Engagement in Early Childhood Education at Home

This study uses data from the 2003 National Assessment of Adult Literacy to identify relationships between parents’ demographic/socioeconomic backgrounds and their self-reported frequencies of engaging in early childhood education activities. It also examines race/ethnicity-related disparities in the frequency of reading to children and using interactive reading techniques after controlling for household income, nativity, and parents’ prose literacy skills. Regression analyses show that White parents are more likely than Black and Hispanic parents to report reading to their children frequently, while Black parents are more likely than White parents to report teaching the alphabet and pointing out words to children.     

Live Showups and Their Influence on a Subsequent Video Line‐up

A live showup (known as a street identification in the UK) allows the perpetrator to be identified shortly after a street crime. If the suspect disputes the identification, a video line‐up often ensues. Four experiments examined the reliability of live showups and their influence on a subsequent video line‐up using realistic procedures and conditions. Similar proportions of culprits and innocent suspects were identified from live showups and video line‐ups. Both culprits and innocent suspects previously identified were likely to be identified again in a subsequent line‐up, with delays from a few minutes to a month. Only a weak effect of clothing bias was observed. There was strong evidence of commitment to a previous identification but no reliable evidence of source monitoring errors. The results suggest that a live showup is not less fair than a line‐up, but the use of repeated identification procedures introduces an unfair bias against innocent suspects.

A Kid-Friendly Tool to Assess Rumination in Children and Early Adolescents: Relationships with Mother Psychopathology and Family Functioning

The early identification of ruminative processes in children and early adolescents is particularly important to prevent the development of a stable ruminative style in later stages of development. The present study first aimed at validating a child-friendly tool, Kid Rumination Interview (KRI), to be used in a sample aged 7–12 years (n?=?100; 50% females). Second, we hypothesized that maternal depression, family functioning and participants’ emotion regulation skills would be associated with children’ levels of rumination. Factor analysis on KRI scores yielded two main factors: personal life-related rumination and school-related rumination. Older and female participants showed higher tendencies to ruminate about school issues compared to their younger and male counterparts. A low-to-moderate correlation emerged between school-related rumination and child/early adolescent’s emotion regulation capacities. Mothers’ depressive rumination and mothers’ depressive symptoms were positively associated with children/early adolescents’ rumination about personal life and rumination about school issues. Conversely, an adequate and positive family functioning was negatively correlated with both school-related rumination and rumination about personal life. Hierarchical regression analyses pointed to a crucial role of maternal rumination and familiar rigidity in both types of rumination. Personal life-related rumination was also specifically predicted by maternal depression and family enmeshment, whereas school-related rumination was significantly associated with children/early adolescents’ emotional control and gender. Overall, the KRI appears as a promising tool to assess rumination in children/early adolescents. Results suggests partially different pathways to specific forms of ruminative thoughts.     

Reliable and Valid Coding of Thin Slices of Video Footage: Applicability to the Assessment of Mother-Child Interactions

When using behavioral-observation methods for coding video footage, it is unknown how much time of an interaction needs to be coded to gain results that are representative for the behavior of interest. The current study examined this problem using the INTAKT, a standardized observational measure for assessing the quality of mother-child interactions. Results from coding only 10 min of each video (i.e., thin slices) were compared with results from coding the remaining parts (averaging about 40 min) of the interaction. Inter-rater agreement for the short versions taken from the beginning or the middle, but not the end of the interactions indicated satisfactory observer accuracy. Coding results did not differ between short and long video sequences, when sequences were taken from the middle of the interactions. Importantly, characteristic differences between different interactive situations were equally well represented in the short and long video sequences. Therefore, our results show that coding only 10 min of an interaction is as reliable and valid as coding full-length videos, if those short sequences are taken from the middle of an interaction. Our findings support the idea that for every method, it is necessary to individually determine the window duration that is long enough to gain results that are reliable and valid.     

The Home Observation for Measurement of the Environment: A rejoinder to Elardo and Bradley''s comment

The published and unpublished research pertaining to Caldwell's Home Observation for Measurement of the Environment (HOME) inventory was recently reviewed by R. Elardo and R. H. Bradley (Developmental Review, 1981, 1, 113–145). Their review was unfortunately deficient in a number of respects. For example, certain methodological issues bearing on the interpretation of the available data were either unrecognized or dismissed without adequate consideration. In addition, some of the data in the studies cited which contradicted or clouded their conclusions were omitted. An extension and reanalysis of the conclusions reached by Elardo and Bradley in light of recently published studies which were not included in their review, and data not discussed in the studies which were reviewed, is provided. Methodological problems are highlighted, and directions for future research are suggested.     

Evaluating Family Interactions to Inform Exhibit Design: Comparing Three Different Learning Behaviors in a Museum Setting

ABSTRACT

How do we know that families are learning during the museum visit itself? In order to address this question, this study focuses on three frequently evaluated indicators of during-visit learning: time spent, exhibit engagement, and interpretive talk. Each of these types of data makes certain assumptions about family learning and how it occurs. Four hundred ninety-three family interactions at 25 different children's museum exhibits were analyzed to examine what the three measures reveal about family learning behavior. When compared, the three measures were not highly correlated, suggesting that generalizing information about the family experience from a single indicator is insufficient. Looking at all three indicators simultaneously can help evaluators begin to explore the relationships between families’ learning behaviors, and think about how exhibit characteristics can influence potential learning opportunities in informal settings.     

Social and Ethical Interactions with Nano: Mapping the Early Literature

There is a rapidly expanding field of research on social and ethical interactions with nano-scaled sciences and technologies. An important question is: What does social and ethical research actually mean when it is focussed on technological applications that are largely hypothetical, and a field of science spread out across multiple disciplines and lacking unification? This paper maps early literature in the field of research as a way of answering this question. Our aim is to describe how this field is developing in response to its difficult task, and particularly, to comment on the topics of focus and where there is potential for future development. We present four topical categories, labelled Governance, Perception, Science and Philosophy, and use these as a tool to both map the field and to analyse its development. We find a majority of literature currently focused on issues of governance and perception, and offer suggestions for why this might be so. We then discuss cross-category themes of definition, novelty and interdisciplinarity, highlighting diverse positions and a problematic lack of direct debate. Our conclusion is that the field would benefit from more interaction, cross-referencing and creative research across traditional fields of inquiry.     

Prevention of Problem Behavior Through Annual Family Check-Ups in Early Childhood: Intervention Effects From Home to Early Elementary School

This randomized intervention trial examined the effects of yearly Family Check-Ups (FCUs) and tailored parent management training on parent report of problem behavior from age 2 to 5 years and teacher report of oppositional behavior at age 7.5. A multiethnic risk sample of 731 families in 3 distinct geographical settings who were receiving assistance from the Women, Infants, and Children Nutritional Supplement (WIC) program were randomly assigned to a yearly FCU. Intention to treat (ITT) analyses were used to examine overall intervention effects, and complier average causal effect (CACE) modeling was used to examine the effects of annual intervention engagement in the FCU on parent reports of child problem behavior from age 2 to 5 and teacher reports of problem behavior at age 7.5. ITT intervention effects were found regarding parent report at ages 2 to 5 and teacher report at age 7.5, indicating less growth in problem behavior for children in the intervention group than for those in the control group. CACE modeling of intervention engagement revealed that the effect sizes on parent- and teacher-reported problem behavior increased as a function of the number of yearly FCUs caregivers participated in. Findings suggest that embedding yearly FCU services within the context of social, health, and educational services in early childhood can potentially prevent early-onset trajectories of antisocial behavior. The increases in effect size with successive FCU engagement underscores the importance of a motivational approach to parenting support among high-risk families.     

Abstract: Comparing Semiparametric and Parametric Methods for Modeling Interactions Among Latent Variables

Many approaches have been proposed to estimate interactions among latent variables. These methods often assume a specific functional form for the interaction, such as a bilinear interaction. Theory is seldom specific enough to provide a functional form for an interaction, however, so a more exploratory, diagnostic approach may often be required. Bauer (2005) proposed a semiparametric approach that allows for the estimation of interaction effects of unknown functional form among latent variables. A structural equation mixture model (SEMM) is first fit to the data. Then an approximation of the interaction is obtained by aggregating over the mixing components. A simulation study is used to examine the performance of this semiparametric approach to two parametric approaches: the latent moderated structures approach (Klein & Moosbrugger, 2000) and the unconstrained product-indicator approach (Marsh, Wen, & Hau, 2004). Data were generated from four functional forms: main effects only, quadratic trend, bilinear interaction, and exponential interaction. Estimates of bias and root mean squared error of approximation were calculated by comparing the surface used to generate the data and the model-implied surface constructed from each approach. As expected, the parametric approaches were more efficient than the SEMM. For the main effects model, bias was similar for both the SEMM and parametric approaches. For the bilinear interaction, the parametric approaches provided nearly identical results, although the SEMM approach was slightly more biased. When the parametric approaches assumed a bilinear interaction and the data were generated from a quadratic trend or an exponential interaction, the parametric approaches generated biased estimates of the true surface. The SEMM approach approximated the true data generation surface with a similarly low level of bias for all the nonlinear surfaces. For example, Figure 1 shows the true surface for the bilinear interaction along with the SEMM estimated average surface. The results suggest that the SEMM approach can provide a relatively unbiased approximation to variety of nonlinear relationships among latent variables.     

Friendship Interactions in Children with and without Depressive Symptoms: Observation of Emotion during Game-Playing Interactions and Post-Game Evaluations

This observational study supplements the strong and consistent link found between childhood depression and deficits in interpersonal functioning by examining the relationship between a high versus low score on the Children’s Depression Inventory (CDI) and children’s emotions when interacting with their best friends. High-CDI and low-CDI target children (n=86) were paired for videotaped game-playing with self-reported best friends. Researchers found that although high-CDI target children were not distinguishable from low-CDI peers in their displays of positive and negative emotion. However, the partners of high-CDI target children displayed significantly more negative emotion during the competitive task and significantly less positive emotion during the cooperative task than did partners of low-CDI target children. In addition, high-CDI target children and their partners reported less enjoyment of their interactions than low-CDI target children and their partners. This combination of findings suggests that depressive symptoms were associated with a relative lack of success achieving an optimal friendship interaction even under highly favorable conditions.
