From the earliest moments in their lives, infants begin to build memories about their past and accumulate knowledge about the world. In this article, we focus on the distinction between memory for "specific" events and memory for "general" information, and the ongoing debate about which type of memory provides the foundation…

The goal of this study was to identify the onset and magnitude of prediction of early cognition to adult socioeconomic outcomes. Specifically, we were interested in examining which cognitive skills measured at 15, 24, 36, and 54 months predict educational attainment and salary at age 26. Data (N = 1364, 52% male) included a diverse sample (76%…

Perception is not an independent, in-the-moment event. Instead, perceiving involves integrating prior expectations with current observations. How does this ability develop from infancy through adulthood? We examined how prior visual experience shapes visual perception in infants, children, and adults. Using an identical task across age groups, we…

We extend decades of research on infants' visual processing by examining their eye gaze during viewing of natural scenes. We examined the eye movements of a racially diverse group of 4- to 12-month-old infants (N = 54; 27 boys; 24 infants were White and not Hispanic, 30 infants were African American, Asian American, mixed race and/or Hispanic) as…

Recent work asked if visual cues facilitate word segmentation in adults and infants (Thiessen, 2010). While adults showed better word segmentation when presented with a regular visual cue (consistent mapping between words and objects), infants did not. This difference was attributed to infants' lack of understanding that objects have labels.…

Anger is a central characteristic of negative affect and is relatively stable from infancy onward. Absolute levels of anger typically peak in early childhood and diminish as children become socialized and better able to regulate emotions. From infancy to school age, however, there are also individual differences in rank-order levels of anger. For…

In the year of 2020, the project of the collective writing on the theme 'Philosophy of education in a new key' (Peters, 2020) was launched to explore possibilities of thinking philosophy of education through collective efforts and intelligence. Its leading tone 'Harmonic Cadence' (Peters, 2020) means that the new field for philosophy of education…

We explain metacognition as a management of cognitive resources that does not necessitate algorithmic strategies or metarepresentation. When pragmatic, world-directed actions cannot reduce the distance to the goal, agents engage in epistemic action directed at cognition. Such actions often are physical and involve other people, and so are open to…

Evolutionary-minded developmentalists studying predictive-adaptive-response processes linking childhood adversity with accelerated female reproductive development and health scientists investigating the developmental origins of health and disease (DOoHaD) may be tapping the same process, whereby longer-term health costs are traded off for…

Niche construction is the modification of components of the environment through an organism's activities. Humans modify their environments mainly through ontogenetic and cultural processes, and it is this reliance on learning, plasticity and culture that lends human niche construction a special potency. In this paper we aim to facilitate…

In this essay, it is argued that a general understanding of human development needs a unified framework based on evolutionary theorizing and cross-cultural and cultural anthropological approaches. An eco-social model of development has been proposed that defines cultural milieus as adaptations to specific socio-demographic contexts. Ontogenetic…

The aim of the present study was to explore and compare systematically the developmental patterns of certain aspects of imitation, longitudinally from 2 to 10 months, in interactions of infants with grandfathers and grandmothers. Sixteen infants were video-recorded at home in the course of spontaneous dyadic interactions with maternal grandfathers…

Packing is a problematic mealtime behavior that is characterized by pocketing or holding solids or liquids in the mouth without swallowing. In the current study, we examined the effects of a chaser, a liquid or solid consistently accepted and swallowed by the child, to decrease packing of solid foods in 3 children with feeding disorders. During…

The influence of phonological (i.e. individual sounds), lexical (i.e. whole-word forms) and semantic (i.e. meaning) characteristics on the words known by infants age 1;4 to 2;6 was examined, using an existing database (Dale & Fenson, 1996). For each noun, word frequency, two phonological (i.e. positional segment average, biphone average), two…

There is evidence for developmental hierarchies in the type of information to which infants attend when reasoning about objects. Investigators have questioned the origin of these hierarchies and how infants come to identify new sources of information when reasoning about objects. The goal of the present experiments was to shed light on this debate…
