The study of Hebrew, a non-European language written in a non-alphabetic (abjadic) script offers valuable insights into the science of reading beyond the well-studied alphabetic scripts. Because reading development in Hebrew is shaped by the uniquely Semitic root-and-pattern morphology and the abjadic (predominantly consonantal) orthography, our…

Dopamine participates in encoding memories and could either encode rewarding/aversive value of unconditioned stimuli or act as a novelty signal triggering contextual learning. Here we show that intraperitoneal injection of the dopamine D1/5R antagonist SCH23390 impairs contextual fear conditioning and tone-shock association, while intrahippocampal…

Our bodies are made up of over 250 specific cell types, and all initially arise from stem cells during embryonic development. Stem cells have two characteristics that make them unique: (1) they are pluripotent, meaning that they can differentiate into all cell types of the body, and (2) they are capable of self-renewal to generate more of…

Developmental change emerges from dynamic interactions among networks of neural activity, behavior systems, and experience-dependent processes. A developmental cascades framework captures the sequential, multilevel, cross-domain nature of human development and is ideal for demonstrating how interconnected systems have far-reaching effects in…

Child maltreatment is a significant problem in North America. Maltreatment comes in many forms, such as neglect, physical abuse, sexual abuse, abandonment, and traumatic world events. The maltreatment affects children's neurobiological development, and thus, potentially their future quality of social and psychological health. This article gives a…

Negation is known to have inhibitory consequences for the information under its scope. However, how it produces such effects remains poorly understood. Recently, it has been proposed that negation processing might be implemented at the neural level by the recruitment of inhibitory and cognitive control mechanisms. On this line, this manuscript…

In a recent theoretical article, I proposed that the efficiency of mitochondrial functioning is the most fundamental biological mechanism contributing to individual differences in general intelligence ("g;" Geary, 2018). The hypothesis accommodates other contributing mechanisms at higher levels of analysis (e.g., brain networks), and is…

This article describes one family's experience in the Young Mother's Clinic (YMC), a medical clinic providing multidisciplinary care to adolescent mothers and their children. The authors highlight the neurodevelopmental changes that occur in the later adolescent period and explore related clinical implications for professionals working with these…

Effective science instruction requires knowledge of subject matter and scientific practices (Next Generation Science Standards (NGSS), 2013), as well as the context within which learning occurs (Anthony, Hunter and Hunter 2014). For science teachers, there is often a tension between the efficiency of lecture and student engagement that comes with…

Adolescence is a period of growing focus on social interactions and relationships. The peer context is one of the most significant developmental contexts in this transitional period and positive peer experiences contribute positively to adolescent well-being. Although negative peer influence on antisocial behaviour has received much attention, we…

Infantile spasms (IS) is a rare epileptic disorder occurring in children under the age of one that can often lead to severe developmental delays throughout life. Though over 200 etiologies have been associated with this disorder, many cases remain unexplained. Research into the etiology of IS has implicated causes such as exposure to prenatal…

In an interview, educator and psychologist Thomas Armstrong says that schools need to do a better job of speaking to--rather than resisting or crushing--adolescents' neurological development. "Essentially, the curriculum in high school needs to be more affective," he argues. "It needs to be more engaging in terms of humor, vitality,…

The relations between the developing mind and developing brain are explored. We outline a theory of intellectual development postulating that the mind comprises four systems of processes (domain-specific, attention and working memory, reasoning, and cognizance) developing in four cycles (episodic, realistic, rule-based, and principle-based…

Empathy is an essential component of human social life. It requires the ability to understand another's mental state and respond with an appropriate emotion or action. Individuals with autism spectrum disorder (ASD) have been described to exhibit atypical empathic responses which limit communication and social interactions. This review highlights…

Education is a socially structured form of learning. It involves the brains of different players--students, teachers, family members, and others--in permanent interaction. The biological set of mechanisms by which these brains receive, encode, store, and retrieve mutually exchanged information is called "neuroplasticity". This is the…
