Age differences in understanding precedent-setting decisions and authorities' responses to violations of deontic rules

Oral narrative skills are assumed to develop through parent-child interactive routines. One such routine is shared reading. A causal link between shared reading and narrative knowledge, however, has not been clearly established. The current research tested whether an 8-week shared reading intervention enhanced the fictional narrative skills of children entering formal education. Dialogic reading, a shared reading activity that involves elaborative questioning techniques, was used to engage children in oral interaction during reading and to emphasize elements of story knowledge. Participants were 40 English-speaking 5- and 6-year-olds who were assigned to either the dialogic reading group or an alternative treatment group. Analysis of covariance results found that the dialogic reading children’s posttest narratives were significantly better on structure and context measures than those for the alternative treatment children, but results differed for produced or retold narratives. The dialogic reading children also showed expressive vocabulary gains. Overall, this study concretely determined that aspects of fictional narrative construction knowledge can be learned from interactive book reading.     

Gender symmetry in intimate aggression: an effect of intimacy or target sex?

Men's greater use of direct aggression is not evident in studies of intimate partner aggression. In previous research, the effects of target sex and relationship intimacy have frequently been confounded. This study sought to examine these effects separately. One hundred and seventy-four participants (59 male and 115 female) read vignette scenarios in which they were provoked by a same-sex best friend, an opposite-sex best friend, and a partner. For each target, participants estimated their likely use of direct physical and verbal aggression as well as noninjurious forms of anger expression. Results showed that men lower their aggression in the context of an intimate partnership and that this is an effect of the target's sex. In contrast, women raise their aggression in the context of an intimate partnership and this is an effect of intimacy with the target. The use of noninjurious angry behavior did not vary between targets for either sex of the participant, which suggests that the effects of target are confined to behaviors which carry an intention to harm. Possible effects of social norms and oxytocin-mediated emotional disinhibition on intimate partner aggression are discussed.     

The three latent classes of adolescent delinquency and the risk factors for membership in each class

This study used latent class analysis to examine subpopulation membership based on self-reports of delinquent behaviors obtained from Australian youth. Three discrete identifiable classes were derived based on 51 indicators of physical violence, property damage, minor infractions, drug use, and social delinquency. One class of youth engaged in primarily rule breaking and norm violations including underage alcohol use, typical of this age period. A second class was more actively delinquent emphasizing drug use, trespassing, and various forms of disobedience. A third class of highly delinquent youth differed from their counterparts by endorsing drug use, thievery that involved stealing money, goods, and cars, property damage, gambling, precocious sexual experiences, involvement with pornographic materials, and fighting. Multinomial logistic regression predicting class membership indicated highly delinquent youth were more likely to be older males, use venting coping strategies, and be fun or novelty seeking compared with rule breakers. Findings are discussed in terms of refining current taxonomic arguments regarding the structure of delinquency and implications for prevention of early-stage antisocial behavior.     

Maternal attachment representations after very preterm birth and the effect of early intervention

Objective

For very preterm infants the mother-infant relationship may be compromised. Maternal attachment representations 18 (corrected) months after very preterm birth and the effect of the post-discharge Infant Behavioral Assessment and Intervention Program (IBAIP) were studied. The IBAIP is designed to assist parents to support and enhance their infant's regulatory competence and development. The intervention consisted of 6-8 home visits during the first 8 months after birth.

Method

Seventy-eight mothers of very preterm infants (<32 weeks and/or <1500 g) were interviewed, who participated in a randomized controlled trial: 41 from the intervention group and 37 from the control group. Maternal attachment representations were assessed with the Working Model of the Child Interview (WMCI). The interviews resulted in a classification of the attachment representations into balanced or non-balanced.

Results

30% of the mothers had non-balanced attachment representations. Qualitative content analysis of the answers showed that negative feelings when first seeing their baby and negative or ambivalent feelings in the first weeks at home with their baby are related to non-balanced attachment representations. The WMCI revealed no differences between the intervention and control group.

Conclusion

Early support for mothers of very preterm born infants to develop a healthy mother-infant relationship is recommended especially for mothers who report negative first experiences.     

Negative stimulus-response compatibility observed with a briefly displayed image of a hand

Manual responses can be primed by viewing an image of a hand. The left-right identity of the viewed hand reflexively facilitates responses of the hand that corresponds to the identity. Previous research also suggests that when the response activation is triggered by an arrow, which is backward-masked and presented briefly, the activation manifests itself in the negative priming effect. The present study showed that response activation, which is produced by an identity of a briefly presented image of a hand, can be similarly associated with a negative priming effect. However, in contrast to the previously reported negative priming effects, the hand stimuli produced negative priming even when the hand was not backward-masked and did not contain task-relevant information. The study supports the view that the automatic inhibition of motor activation triggered by briefly viewed objects is a general and basic functional principle in exogenous motor control processes.     

Differential recruitment of executive resources during mind wandering

Recent research has shown that mind wandering recruits executive resources away from the external task towards inner thoughts. No studies however have determined whether executive functions are drawn away in a unitary manner during mind wandering episodes, or whether there is variation in specific functions impacted. Accordingly, we examined whether mind wandering differentially modulates three core executive functions—response inhibition, updating of working memory, and mental set shifting. In three experiments, participants performed one of these three executive function tasks and reported their attentional state as either on-task or mind wandering at random intervals. We found that mind wandering led to poorer performance in the response inhibition and working memory tasks, but not the set-shifting task. These findings suggest that mind wandering does not recruit executive functions in a monolithic manner. Rather, it appears to selectively engage certain executive functions, which may reflect the adaptive maintenance of ongoing task performance.     

不同搜索情境下老化对自上而下注意加工的影响

在视觉搜索过程中,老年人是否可以在不同情境下调节自上而下和自下而上的加工水平尚不明确。为了探讨老化对认知灵活性的影响,研究采用空间线索范式,通过比较有效线索和无效线索来考察对线索的注意加工水平（注意捕获、注意抑制）,通过比较目标相关和目标无关线索的注意加工水平来考察自上而下和自下而上的作用,通过改变分心物一致性来调控不同的目标凸显情境。结果发现,年轻组在目标非凸显时的空间线索效应高于目标凸显时,表明年轻人会依据目标凸显性调整自上而下的加工水平;但老年组却没有产生这种差异,其更依赖自上而下的加工,注意系统会对目标相关的线索进行注意捕获,对目标无关的线索进行注意抑制。结果表明,随着年龄的增长,认知控制的灵活性下降,表现出对自上而下加工较多的依赖;此外,老年人依然保留着注意捕获和注意抑制的能力,这对认知老化中抑制能力受损的观点提出了挑战。     

Learning from parents' stories about what works in early intervention

Using a multiple case study approach, this ethnography examined the experiences of parents of children deemed at risk for developmental delays or disabilities who had received early intervention (EI) services (birth to age 3 years) in a large urban location in Western Canada. Participants (11 adult parents and 7 children) were drawn from six families. Methods of data collection included focus groups (FG), face‐to‐face interviews and file reviews. Member check and expert reviews were conducted throughout data collection and data analyses as part of the validation process in this ethnography. Qualitative content analyses followed by thematic analyses highlighted the implementation of family‐centred practices (FCP) as a main theme. Parents identified how EI professionals using FCP embraced collaborative practices. FCP resulted in parents leading the EI process for their children. More specifically, EI professionals shared strategies and information to support parents in gaining a deeper understanding of their children's individual developmental characteristics. Parents expressed how empowering this level of understanding was for them as they learned to articulate what were their children's needs for developmental, health and educational services. Recommendations for future research include inquiring about parents' experiences for families of diverse constellations and/or residing in smaller urban or rural communities.     

First symbols in a girl with Down syndrome: A longitudinal study from 12 to 18 months

Symbolic uses of objects originate in communicative and triadic contexts (adult–child-object). In this longitudinal study we explore the emergence and development of the first symbolic uses in triadic interaction contexts in a girl with Down syndrome between 12 and 18-months of age. We conducted five sessions of video recording, at 12, 13½, 15, 16½, and 18 months chronological age. At each session we videotaped the girl and her mother interacting with different objects. Data were coded in semiotic categories used in previous studies (Rodríguez & Moro, 1999) and a microgenetic analysis was conducted for each session. The first symbolic uses by the girl appeared at 13½ months. Symbols were of different types and levels of complexity, and the adult had an important role in facilitating the production of these symbols.
