Two studies examined the proposed Nominal Passover Effect, whereby toddlers pass over a novel--though repeated--label for a familiar object. Found that the passover experience was often sufficient to counteract children's tendency to generalize a novel label on the basis of perceptual similarity. (HTH)

Children with mental retardation have pronounced difficulties in using cognitive strategies and comprehending abstract concepts--among them, the concept of sequential time (Van-Handel, Swaab, De-Vries, & Jongmans, 2007). The perception of sequential time is generally tested by using scenarios presenting a continuum of actions. The goal of this…

This study examined changes in rhythmic arm shaking and laterality biases in infants observed longitudinally at three points: just prior to, at, and just following reduplicated babble onset. Infants (ranging in age from 4 to 9 months at babble onset) were videotaped at home as they played with two visually identical audible and silent rattles…

A review of significant research on subliminal perception and a summary of evidence for and against it. (Author)

An experiment with monochromatic lights is discussed in terms of the selective effects of wavelength on looking time and pleasantness, comparisons of infant and adult data, and differentiation of the selective effects of color category centers and color category boundaries. (JMB)

In this paper, data generated in the intermediate-size transposition paradigm under a variety of experimental conditions are related to a 2-process model involving perceptual and cognitive components. (Author/JMB)

Two experiments were conducted to demonstrate that human infants 3 months of age perceive color in a normal, trichromatic manner. Results from these studies of the neutral zone and hue discrimination evidence trichromatic vision in infancy and are discussed in the context of their clinical, social, and intellectual implications. (Author/SB)

Differential looking and manipulation were assessed in 44 six-month-old infants who were presented with familiar and novel visual stimuli. The infants looked at the novel stimuli longer. (ST)

Reports five studies of children's attention to various characteristics or attributes relating to concept formation. (ST)

To establish the spatial generality of perseverative errors in infant manual search, a group of infants aged 8-11 months performed Piaget's Stage IV task with an object hidden at successive locations in the vertical plane. (Author/JMB)

Reports on three experiments showing the crucial importance of the "half boundary" in children's proportional judgments. Concludes that the concept of "half" plays a crucial role in children's early proportional reasoning and that the half boundary is similar to, though not as powerful as, the category boundaries discovered in…

This study investigated 3- and 4-year-old's understanding of the relationship between pretense and mental awareness. In Experiments 1 and 2, only a subset of 4-year-olds recognized that sleeping characters and characters ignorant of their appearance were not pretending. However, these experiments had certain linguistic demands, which potentially…

Most international adoptees (IA) have rapid catch-up of the delays common at arrival. However, it is not known whether development at arrival predicts later abilities or school readiness. Therefore, we comprehensively evaluated language, fine motor, visual reception (VR), executive function (EF), attention (ATT), and sensory skills (SS) in IA…

This study examined the effectiveness of Sensory Stories on "circle time" behaviors in preschool children with autism. This single-system ABA design with a convenience sample of four participants consisted of one week for each A phase and two weeks for the B phase. The intervention phase (B) consisted of reading a Sensory Story from one…
