Although developmental psychologists are generally happy to endorse dissociations and gradualist views of development like Woolley's (2006), the design and interpretation of developmental research often suggests an implicit commitment to a cleaner, less dissociative, sudden-transition view of development. Such an implicit commitment may derive…

The grounding of symbols in computational models of linguistic abilities is one of the fundamental properties of psychologically plausible cognitive models. In this article, we present an embodied model for the grounding of language in action based on epigenetic robots. Epigenetic robotics is one of the new cognitive modeling approaches to…

Based on stimulating findings suggesting that prenatal levels of steroids may influence cognitive functions, a study with N=40 healthy volunteers of both sexes was conducted. Prenatal levels of testosterone (T) were estimated by use of the second-to-fourth digit ratio (2D:4D) which is supposed to be controlled by the same genes involved in…

The field of children's learning was thriving when the Merrill-Palmer Quarterly was launched; the field later went into eclipse and now is in the midst of a resurgence. This commentary examines reasons for these trends, and describes the emerging field of children's learning. In particular, the new field is seen as differing from the old in its…

Student achievement gaps among racial and ethnic groups are large and persistent. They mirror gaps in life and school conditions that have been found to be closely related to cognitive development and school achievement. The road to parity begins with understanding the nature of the gaps and their trends. One way the size of the gap has been…

Given the consistent findings of theory of mind deficits in children with autism, it would be extremely beneficial to examine the profile of theory of mind abilities in other clinical groups such as fragile X syndrome (FXS) and Down syndrome (DS). The aim of the present study was to assess whether boys with FXS are impaired in simple social…

The construction of healing narratives is a framework within which the college counselor can view the progressive development of the counseling process. The level of a client's narrative processing appears to depend on an interaction between experience-specific knowledge and experience-specific emotionality. Implications for college counselors and…

Children aged 2 and 3 years were tested for a previously neglected form of knowledge about visual perception; namely, whether an observer can see a figure that is partially occluded. The results indicate that for children of this age the visibility of a figure's face is crucial for judging visibility, whereas the visibility of the legs is not.…

This study investigated how 4- to 7-year-old children's second-order belief attribution might be facilitated by either reducing information processing or varying the sequence of task questions. In Experiment 1, compared with Perner and Wimmer's (1985) original second-order false-belief task, a new task with reduced information-processing demands…

This study examined age-related change in the ability to inhibit responses using two varieties of the stop signal paradigm. Three age groups (29 7-year-olds, 24 10-year-olds, and 28 young adults) performed first on a visual choice reaction task in which the spatial mapping between the go signal and response was varied between blocks. The choice…

The capacity to attribute beliefs to others in order to understand action is one of the mainstays of human cognition. Yet it is debatable whether children attribute beliefs in the same way to all agents. In this paper, we present the results of a false-belief task concerning humans and God run with a sample of Maya children aged 4-7, and place…

Two experiments examined the effect of age and cognitive demands on children's choice strategies. Children aged 8-9 and 12-13 years were asked to choose among either two or four products that differed in several attributes of varying importance to them. Choice tasks were designed to differentiate between the lexicographic and the equal-weighting…

Calendrical calculation is the unusual ability to name days of the week for dates in the past and sometimes the future. Previous investigations of this skill have concerned savants, people with pervasive developmental disorders or general intellectual impairment. This research has yielded a hypothesis about how calendrical skills develop but no…

Two experiments examined how internal and external supports affected planning for enabling (logically linked) and conventional (arbitrarily linked) events. In Experiment 1, preschoolers were given either two or four training sessions before planning and enacting invariably sequenced art projects. In Experiment 2, preschoolers were given two…

Neurological research has demonstrated that brain activity in animals originally dedicated to the production and regulation of physical activity can be decoupled from that physical activity. Furthermore, animals can use the brain activity in this new condition to achieve particular results such as moving a cursor on a screen. These findings are…
