Prerequisites: None
Offered: Spring, Summer
This course is an introduction to human development, focusing on the ability to perceive objects and sounds, to think
and reason, to learn and remember language and other significant patterned stimulation. It includes discussion of the
nature and mechanisms of development in human infants and children, as well as an overview of what is known about the
development of behavior and brain in the young of other species.
The general framework of the course will be the 'nature/nurture issue': how is the development of high-level mental
processes shaped by innate factors, how is it shaped by environmental factors and learning, and how do these factors
interact in the developmental process? In order to consider these factors and their interaction, the course will begin
by studying the development of interesting species-typical behaviors in animals; for example, we will examine the
acquisition of songs and calls by birds, the acquisition of nest building by various species, the 'imprinting' of ducks
and birds on other members of their species, and the calibration of visual and spatial abilities in owls and cats. This
overview of animal development will provide us with a background to the types of interactions between biology and learning
that are understood to occur in non-humans. We will then overview the development of the brain in animals and humans.
With these backgrounds we will then turn to considering the development of a variety of aspects of perception, cognition,
and language in human infants and children.
Our focus on humans will begin with the study of the ability to see and hear in newborn infants, and how these senses
develop prenatally and over the first year of life. We will then examine the ability of human infants to understand the
physical world: how they acquire the knowledge that objects are solid, usually rigid, and continue to exist even when they
are out of view. We will also consider how they begin to understand that animate objects (particularly other people) move
through the world by a somewhat different set of principles than those that govern inanimate objects. Next we will consider
how memory and complex concepts develop, and how young children acquire more advanced abilities to think and reason.
Finally, we will examine how infants learn their native languages, which begins with organizing the sounds of these languages
and culminates in the learning of how to form words and sentences. In each of these arenas we will discuss the contributions
of innate tendencies or knowledge, the contributions of learning from experience, the possible interactions of these sources
of information, and the domains in which there may be critical or sensitive periods of development, in which learning is
limited to a specific maturational window. Throughout these topics we will also discuss the methods by which scientists study
human development, particularly the unusual methods which have been devised to study young infants in the laboratory, and we
will encourage students in the class to begin to think about how they might study some of these questions themselves.
No previous background is assumed. This course will provide an introduction to the area suitable for students of any
background. Completion of the course will provide appropriate background for a range of higher level courses (some of
these also require BCS 110 or 111), may form part of a major in Brain & Cognitive Sciences, Psychology, Linguistics,
Cognitive Science, or other concentrations, and will be particularly useful for students hoping to pursue a career in any
natural or social sciences involving development.
