Previous researchers have argued that objects associated with a protagonist may be foregrounded, or held active, in memory. This study expanded on previous work by using an inconsistency paradigm to investigate the effects of protagonist association on object accessibility. Readers experienced more processing difficulty when a target sentence…

We used a reference memory paradigm to examine whether 4- and 5-year-old children could be trained to use landmark features to relocate targets after disorientation. In Experiment 1, half of the children were pretrained in a small equilateral triangle-shaped room. Each of the three walls was a different color, and the target was always in the…

Within a small bounded space, the location of a hidden object can be coded in terms of distance information, general area of hiding, or the boundary of the space. The use of these three coding strategies by infants was examined using a visual search task. Results indicated boundary information and the nature of the change influenced coding of…

Episodic memory in humans is the conscious recollection of a past event. Animal models of episodic-like memory assess the memory for "what" happened, "where" it happened, and either "when" it happened, or in "which" context it happened, although recollection on such tasks is often difficult to measure. Here we present the first evidence of…

Critically evaluates habituation and related models for studying infant memory, focusing on methodological and substantive limitations which restrict the derivation of information from them. The essay considers existing research on the development of object permanence as an alternative source of information about infant memory. (Author/DB)

Examined event-based memory in three groups of children between ages 14 and 25 months. Found that search task success was general in oldest group while performance was similar on a task in which success "may" have been due to recalling an object-removal event and one in which success could "only" have been due to recall of…

Reports two experiments in which eight patients with organic memory disorders exhibited a pattern of search behavior that resembled mnemonmic precedence--the ability to retrieve an object at an initial location, but not at a new location. (HOD)

Maintains that Muller and Overton (1998) misrepresent her theory of infant concept formation in infancy, makes corrections to their representation, and notes that her theory was developed in part because of the lack of detailed mechanisms in Piaget's theory to account for concept formation. Argues that Muller and Overton's proposed alternative…

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…

Premature infants with subependymal or intraventricular hemorrhage took longer to habituate on a habituation task, and scored lower on a measure of mental development, than did other premature infants or full-term infants. Both groups of premature infants were less successful than full-term infants on an object permanence task. (BC)

Infants' abilities to identify objects based on their perceptual features develop gradually during the first year and possibly beyond. Earlier we reported [Kaldy, Z., & Leslie, A. M. (2003). Identification of objects in 9-month-old infants: Integrating "what" and "where" information. Developmental Science, 6, 360-373] that infants at 9 months of…

Examines development of representational thought from the perspective of Jean Mandler's image-schema theory and an action-theoretical approach derived from Piaget's theory. Concludes that empirical findings fail to support hypotheses of early onset, and that representational development is more adequately interpreted within the context of an…

Four experiments examined 8- to 12-month olds on search and nonsearch A not B tasks, a one-location task, and control tasks. Results indicated memory for where object was hidden and expectations of where it should be found. The effect occurred at delays at which infants made the A not B error when searching, and at a longer 15-second delay.…

Examines evidence that the research community studying infants' object concept and the community concerned with adult object-based attention have been studying the same natural kind. Maintains that the discovery that the object representations of young infants are the same as the object files of mid-level visual cognition has implications for both…

Prior to considering the ability of infants to think, this discussion attempts to dispel prevalent myths about babies' thought processes. The fact that infants do not intentionally manipulate their parents; are not identical; are not simply hedonistic seekers of bodily pleasures; and are not passive, disorganized beings needing training into…
