Infants aged 3, 5, and 7 months were shown solid objects and comparable intangible images of objects both within and beyond possible arm's reach. The infants' emotional reactions and reaching behavior in the presence of the image stimuli were found to be very similar to their responses to the solid objects. (Author/JMB)

In two experiments, forty 26-week-old infants were repeatedly exposed to an object and were then shown an object that was different from the original object in color, shape and/or texture. Results showed that looking and manipulation increased for the novel shape and texture objects and looking increased for the novel color object. (Author/JMB)

A six-month-old infant who can remove a transparent cloth from his hand when it is covered after he grasps a toy may not be able to remove an opaque cover. Alternative interpretations of the phenomenon, that is, degree of bimanual coordination and focus of attention, are discussed. (Author/MB)

This study investigated infants' differential responding to novel and familiar stimuli after familiarization in a different sensory modality. Results showed that infants gain information about the shape of objects from their oral experience with them and that this information can be transferred to the visual modality. (Author/JMB)

Results are discussed in terms of cognitive growth, the psychoanalytic notion of ambivalence, the role of stimulus context in eliciting laughter or fear, and a possible adaptive, stimulus-maintaining function of laughter. (Authors)

Examines the ability to differentiate appearance-reality and Level Two perspective-taking in tactile modality among a total of 92 children aged two-four years in three studies. The results indicate that three-year-olds find tactile appearance-reality and Level Two perspective-taking tasks easier than visual ones. (RJC)

Explored in 2 studies 3- and 4-year-olds' understanding that the 5 senses can each lead to different types of knowledge. Found that 3-year-olds performed significantly poorer than 4-year-olds on all tasks, suggesting a marked transition in children's ability to recognize the origin of their modality-specific knowledge between 3 and 4 years.…

Analysis of 40 first-grade children's performance on two discrimination learning problems revealed that children do transfer dimensional information between the visual and tactual modalities. (Author/JMB)

Infants of 12 months were tactually familiarized with either a hard or an elastic substance. Subjects subsequently were shown films of objects moving in patterns characteristic of either hard or elastic objects, and their eye movements were detected. Results suggested that quite young infants detect intermodel invariants specifying some substances…

Two experiments were conducted to investigate six-month-old infants' recognition memory for the shape of an object following unimodal (visual) and bimodal (visual and haptic) familiarization. Visual recognition memory was evident only when the conditions of familiarization and testing were identical. Two possible explanations are presented and…

Three experiments examined whether 8.5-month-olds considered an object's width and compressibility when determining whether it could be inserted into a container. Results suggested that infants realized that large balls could fit into large but not small containers, whereas small balls could fit into both containers. Infants understood that large…

Three experiments examined cross-modal transfer of shape between touch and vision in 1-month-olds, controlling for side bias and stimulus preference. Results did not provide good evidence that 1-month-olds can transfer information about smooth or nubby shapes from touch to vision. Findings highlight the need to control for side bias and stimulus…

Emphasizes the role that motor development may play in determining developmental sequences in other domains, such as haptic or tactile perception and depth perception. Maintains that there is a high degree of fit between the developmental sequence in which certain perceptual sensitivities unfold and the ages at which the corresponding motor…

In comparison with full-term infants, seven-month-old high-risk preterm infants exhibited deficits in visual recognition memory and in the ability to recruit, sustain, and shift attention. (RH)

Results reaffirm the notion that retarded individuals are less adept at recognizing familiar forms haptically than visually. (Author)
