Understanding of preterm infant cognitive competences across the first year of life is limited regarding the developmental constructs of continuity, stability, coherence, and predictive validity as well as how they manifest by age and country of origin. This prospective longitudinal study examined and compared mean-level continuity,…

Sixty infants divided evenly between 5 and 7 months of age were tested for their knowledge of object continuity versus discontinuity with a predictive tracking task. The stimulus event consisted of a moving ball that was briefly occluded for 20 trials. Both age groups predictively tracked the ball when it disappeared and reappeared via occlusion,…

Aim: Cognitive visual dysfunctions (CVDs) reflect an impairment of the capacity to process visual information. The question of whether CVDs might be classifiable according to the nature and distribution of the underlying brain damage is an intriguing one in child neuropsychology. Method: We studied 22 children born preterm (12 males, 10 females;…

The relationship between vision and mental functioning was investigated in a study of 295 elderly residents from three levels of care. Visual acuity and mental status were assessed. Findings indicate that there was indeed a relationship between vision and mental status. (Author)

A study investigated the ability of six individuals with mental retardation to focus on task-relevant elements of complex visual arrays and increased visual-search efficiency. Results found participants were able to limit attention to the task-relevant items on a guided search task, thus greatly reducing overall target identification times.…

A two-process model of infant visual attention is constructed based on research using the modified Berlyne technique with three- to five-month olds. The length of time an infant fixated a pattern was examined along with what caused him to turn to the pattern at all. The study was based both on a re-examination of previous research and on new…

During a longitudinal in-depth study of the reading acquisition and cognitive and visual development of four children with cerebral visual impairment, the children's visual acuity improved, but their full-scale IQs declined, mostly because of difficulties in abstract thinking, visual cognitive organization, and extremely low processing speed. The…
