Middle-schoolers have always been selectively sullen, shamelessly self-absorbed, and hopelessly obsessed with winning the admiration of their peers. In some ways, the preadolescent brain can't keep up with the demands on it. The frontal lobes, where organization and judgment and reasoning reside, aren't as well developed as the emotional centers.…

In this study, we investigated patients with focal neurodegenerative diseases to examine a formal linguistic distinction between classes of generalized quantifiers, like "some X" and "less than half of X." Our model of quantifier comprehension proposes that number knowledge is required to understand both first-order and higher-order quantifiers.…

This review presents the most recent research concerning neuroimaging in developmental disabilities. Changes in structure and activation have been found in children with ADHD and learning disabilities, following intervention. For the children with learning disabilities changes in activation have been found following intensive behavioral and…

Frontal lobe patients reproduced a sequence of capital letters or abstract shapes. Immediate and delayed reproduction trials allowed the analysis of short- and long-term memory for time order by means of suitable Markov chain stochastic models. Patients were as proficient as healthy subjects on the immediate reproduction trial, thus showing spared…

The leading cause of death and injuries in school age children is acquired brain injury (Savage & Wolcott, 1994). Each year approximately 1 in 450 school age children and 1 in 200 adolescents/young adults suffer an injury as a result of some form of acquired brain injury. Approximately 27,000 students in the Ontario school system have acquired…

In this article Tortora, a dance therapist, interviews Myron Hofer, director of the Sackler Institute for Developmental Psychobiology, Columbia University. Dr. Hofer has spent decades studying how the mother's behaviors and actions shape and regulate the physiological, neurophysiological, and psychological functioning of her babies--specifically,…

The author describes recent findings on the neurobiological mechanisms involved in perceptions of risk and safety. The term "Neuroception" describes how neural circuits distinguish whether situations or people are safe, dangerous, or life threatening. Neuroception explains why a baby coos at a caregiver but cries at a stranger, or why a…

This paper suggests that some neuroscience concepts particularly concerned with brain pathways in trauma and fear, as well as the neurobiology of emotion, provide an additional vertex to the psychoanalytic understanding of patients' material. The role of the body has been neglected in psychoanalytic thought and formulations in favour of purely…

Background: In this study we used event-related potentials (ERPs) and source localization analyses to track the time course of neural activity underlying response monitoring in children diagnosed with an anxiety disorder compared to age-matched low-risk normal controls. Methods: High-density ERPs were examined following errors on a flanker task…

Background: Recent investigations suggest that experience plays an important role in the development of face processing. The aim of this study was to investigate the potential role of experience in the development of the ability to process facial expressions of emotion. Method: We examined the potential role of experience indirectly by…

We examined the development of some features of morphosyntactic ability, specifically the acquisition of auxiliaries and use of agreement marking, along with sentence processing capacity. We used a conceptually simple task called the Tags Question Task, which is a method for evaluating a number of language processes in the production of a commonly…

Grammaticality judgments and processing times associated with violation detection were examined in typically developing children, children with focal brain lesions (FL) acquired early in life, and children with specific language impairment (SLI). Grammatical sensitivity in the FL group, while below typically developing children, was above levels…

Objective: To assess the phenomenology and predictive factors of attention-deficit/hyperactivity disorder (ADHD) after traumatic brain injury (TBI), also called secondary ADHD (SADHD). Method: Children without preinjury ADHD 5-14 years old with TBI from consecutive admissions (n = 143) to five trauma centers were observed prospectively for 6…

There is evidence that IQ tends to be higher in those who were heavier at birth or who grew taller in childhood and adolescence. Although these findings imply that growth in both foetal and postnatal life influences cognitive performance, little is known about the relative importance of brain growth during different periods of development. We…

This study examined how school-aged children process different grammatical categories. Event-related brain potentials elicited by words in visually presented sentences were analyzed according to seven grammatical categories with naturally varying characteristics of linguistic functions, semantic features, and quantitative attributes of length and…
