REVIEW
Joan Stiles
Throughout much of the 20th century, the major models of brain development were strongly deterministic. It was thought that brain development proceeds via a prescribed blueprint that is somehow innately specified in the organism. Contemporary models present a distinctly different view of both inheritance and brain development. First, we do not inherit blueprints or plans, we inherit genes and the cellular machinery for expressing them. Genes carry essential information for creating proteins, but do not determine biological processes or developmental outcomes; the first cells contain the elements necessary for creating proteins based on the information coded in the nucleotide sequences of genes...

Although contemporary psychoanalysis is split into different schools and traditions, there is growing support for some of the main tenets of contemporary psychodynamic thinking from attachment theory, infant research, developmental psychopathology, new models of motivation, the neuroscience of emotions and emotional regulation, and the discovery of different implicit and explicit memory systems. These tenets, which psychodynamic clinicians of all stripes encounter in their daily work with clients, are the following: (1) that large footprints are left over from infancy and childhood which involved insensitive, intrusive, frightening, or shaming care; (2) the carryover of these relational experiences into adulthood are expressed as unconscious expectations and attributions we make of others (transference and countertransference; (3) defensive processes and emotional regulation and deregulatory patterns develop to cope with these unhealthy relations...

Characterizing the nature of linguistic representations and how they emerge during early development is a central goal in the cognitive science of language. One area in which this development plays out is in the acquisition of dependencies-relationships between co-occurring elements in a word, phrase, or sentence. These dependencies often involve multiple levels of representation and abstraction, built up as infants gain experience with their native language. The authors used the Headturn Preference Procedure to systematically investigate the early acquisition of 1 such dependency, the agreement between a subject and verb in French, at 6 different ages between 14 and 24 months...

Efforts to prevent melanoma, especially for those at elevated risk for the disease, should ideally begin during childhood. However, there are few preventive interventions targeting children who are at higher risk for melanoma due to a family history of the disease. Further, there are no educational interventions that aim to help these at-risk children understand their risk for melanoma and the ways in which preventive behaviors, such as sun protection, can mitigate their risk. The current paper describes a multidisciplinary team's process for creating a developmentally appropriate educational intervention about melanoma risk and prevention for children ages 8-17 years who have a family history of melanoma...

A sudden influx of portrayals of 'extraordinary children' emerged in British science fiction after the Second World War. Such children both violated and confirmed the new set of expectations about ordinary childhood that emerged from the findings of developmental psychologists around the same time. Previous work on extraordinary children in both science fiction and horror has tended to confine the phenomenon to an 'evil child boom' within the American filmmaking industry in the 1970s. This article suggests that a much earlier trend is visible in British postwar science fiction texts, analysing a cluster of novels that emerged in the 1950s: Arthur C...

Regenerative engineering has been defined as the convergence of Advanced Materials Sciences, Stem Cell Sciences, Physics, Developmental Biology and Clinical Translation for the regeneration of complex tissues and organ systems. Anterior cruciate ligament (ACL) reconstruction necessitates the regeneration of bone, ligament and their interface to achieve superior clinical results. In the past, the ACL has been repaired with the use of autologous and allogeneic grafts, which have their respective drawbacks. Currently, investigations on the use of biodegradable matrices to achieve knee stability and permit tissue regeneration are making promising advancements...

The recently proposed Social Motivation theory (Chevallier et al., Trends in cognitive sciences 16(4):231-239, 2012) suggests that social difficulties in Autism Spectrum Condition (ASC) might be caused by a difference in the motivation to engage with other people. Here we compared adolescents with (N = 31) and without (N = 37) ASC on the Choose-a-Movie paradigm that measures the social seeking. The results showed a preference for viewing objects over smiling faces in ASC, which is in line with the theory of low social motivation...

REVIEW
Rebecca L Gómez
Statistical structure abounds in language. Human infants show a striking capacity for using statistical learning (SL) to extract regularities in their linguistic environments, a process thought to bootstrap their knowledge of language. Critically, studies of SL test infants in the minutes immediately following familiarization, but long-term retention unfolds over hours and days, with almost no work investigating retention of SL. This creates a critical gap in the literature given that we know little about how single or multiple SL experiences translate into permanent knowledge...

At the onset of vocal development, both songbirds and humans produce variable vocal babbling with broadly distributed acoustic features. Over development, these vocalizations differentiate into the well-defined, categorical signals that characterize adult vocal behaviour. A broadly distributed signal is ideal for vocal exploration, that is, for matching vocal production to the statistics of the sensory input. The developmental transition to categorical signals is a gradual process during which the vocal output becomes differentiated and stable...

The Developmental Origins of Health and Disease (DOHaD) scientific field investigates the influence of early life environmental stressors on later life health outcomes. Environmental chemical exposures are a particular focus area within this field. Although the DOHaD hypothesis originated in the 1990s, the data evaluating this hypothesis in environmental epidemiology has not been comprehensively summarized. We conducted a scoping literature review to describe the human evidence for the DOHaD hypothesis and to identify, 1) where there may be reasonable data to draw conclusions, and 2) areas warranting further research...

A large body of cognitive research has shown that people intuitively and effortlessly reason about the biological world in complex and systematic ways. We addressed two questions about the nature of intuitive biological reasoning: How does intuitive biological thinking change during adolescence and early adulthood? How does increasing biology education influence intuitive biological thinking? To do so, we developed a battery of measures to systematically test three components of intuitive biological thought: anthropocentric thinking, teleological thinking and essentialist thinking, and tested 8th graders and university students (both biology majors, and non-biology majors)...

STUDY QUESTION: Can the histone deacetylase inhibitor Scriptaid improve the efficiency of the development of round spermatid injection (ROSI)-fertilized embryos in a mouse model? SUMMARY ANSWER: Treatment of ROSI mouse zygotes with Scriptaid increased the expression levels of several development-related genes at the blastocyst stage, resulting in more efficient in vitro development of the blastocyst and an increased birth rate of ROSI-derived embryos. WHAT IS KNOWN ALREADY: The full-term development of embryos derived through ROSI is significantly lower than that following ICSI in humans and other species...

We are recognizing increasingly that the study of cognitive, social, and emotional processes must account for their embodiment in living, acting beings. The related field of embodied cognition (EC) has coalesced around dissatisfaction with the lack of attention to the body in cognitive science. For developmental scientists, the emphasis in the literature on adult EC on the role of the body in cognition may not seem particularly novel, given that bodily action was central to Piaget's theory of cognitive development...

Evelyn Fox Keller wrote first biography of the Nobel Prize winning geneticist Barbara McClintock in which Keller discussed how McClintock felt being rejected by her peers in the 1950s because she questioned the dominant idea of the particulate gene and instead proposed that the genetic material jumped positions on the chromosome which indicated that the gene did not control but was controlled by the cellular environment. Keller's story of McClintock's life is an account of a woman scientist's conception of science and how her unorthodox views isolated her from the main stream science...

BACKGROUND: In spite of the well-known harmful effects on the fetus, many women continue smoking during pregnancy. Smoking as an important source of toxic chemicals may contribute to the developmental origin of diseases. OBJECTIVES: The aim of this work was to pursue the possible association between maternal smoking and cancer in early life. Specifically, we wanted to identify the associated early life cancer types, and to quantify the associations. METHODS: In a systematic literature search 825 articles were identified in PubMed and Web of Science, and 55 more through the reference lists...

BACKGROUND: Avascular necrosis (AVN) is a significant and potentially devastating complication following the treatment of developmental dysplasia of the hip (DDH). The reported rate of AVN following closed reduction for DDH ranges from 4 to 60%, and the resultant influence on hip development remains unclear. PURPOSE: A systematic review of the literature was undertaken to evaluate the frequency of AVN after more than 5 years of follow-up in children that underwent closed reduction at younger than 2-years of age for DDH...
