Morningness and eveningness: issues for study of the early ontogeny of these circadian rhythms

Article Abstract:

The research by Cofer et al on the ontogeny of Morningness and Eveningness points to a physiological basis to the development of circadian rhythms. The origins of this rhythms begins early in life and even at the prenatal stage. The rhythms are established due to light exposure and its effects are transported to the fetus during pregnancy. Once the rhythmic patterns are established, they will be very difficult to alter later in life, even if affected by social experience. Research on the effects of sleep during developments will require new perspectives and research strategies.

Primacy of action in early ontogeny

Article Abstract:

Ulrich Muller and Willis F. Overton's study on the development of representational thought in infants manages to demonstrate the feasibility of Piaget's action-theoretical perspective on cognitive development. However, the study fails to provide evidences proving that the development of practical intelligence is linked with the emergence of representational abilities in less than a year old infants. This implies that the relation between action, visual perception and cognition in early ontogeny needs further empirical exploration.

Babies think before they speak

Article Abstract:

Each of the claims by Ulrich Muller and Willis F. Overton regarding image-schemas and the process of perceptual analysis in their study on the development of representational thought in infants is erroneous. Their theory that sensorimotor knowledge is accessible to consciousness is untenable. They also fail to provide evidences to prove that infants cannot recall an event sequence and that deferred imitation does not imply representational thought.
