This report deals with research presently being done dealing with the acquisition of musical skills. In an attempt to create a self-paced, independent music study approach, investigators have formulated two main hypotheses: (1) that perception and cognition are inextricably intertwined - not discrete quantities; and (2) that learning behavior in…

According to the theory of Piaget, until the age of two the chief developmental factor of a child is the permanence of an object or the ability to retain mental images. Between two and six he begins to use mental images, and as he develops the ability to retain a mental image he begins to imitate things from the past which he has seen or…

This research project assessed: (1) the practicality of recording heart rate in 18-month-old infants as they watched events filmed on color, silent motion picture films; and (2) the validity and sensitivity of heart rate change as an index of differential attention arousal elicited by changes within and between complex visual events. The research…

Two experiments investigated the role of children's spontaneous conceptual "biases" in pictorial discrimination learning. The results suggested that such biases may serve either to facilitate or to interfere with discrimination learning. Moreover, in each experiment, age by treatment interactions revealed that in comparison to the behavior of…

Western psychologists define "set" as a group of items, a disposition toward certain stimuli or certain responses, and the establishment of habitual actions. D. N. Uznadze explains "set" by postulating a general tendency toward habitual action, but qualifies this by stating that the tendency is governed by special factors…

Section I of this report discusses the theoretical issues relating to the development of syntax recognition routines based on psychological models of human speech recognition and reviews the relevant psychological literature. The research reported deals with attempts to relate various syntactic variables to measures of the perceptual complexity of…

Thirty-two children each in grades 1-5 participated in an experiment designed to replicate and extend a study by Flavell and associates (1972) which hypothesized that "memorizing and perceiving are functionally undifferentiated for the young child, with deliberate memorization only gradually emerging as a separate and distinctive form of cognitive…

The experiments discussed in this report do not have a direct relationship to each other but represent work on a series of sub-issues within the general framework of visual processing of information. Because of this discreteness, the report is organized into a series of papers. The first is a general review of tachistoscopic work on iconic memory…

This study investigated the perceptual functioning of individuals whose Minnesota Multiphasic Personality Inventory (MMPI-168) profiles indicated schizophrenic tendencies, but who did not exhibit marked thought disorder. (Author)

Describes children's reactions to chance and probability in a variety of experimental situations, using four different experiments from Piaget's work, to give a clearer picture of how children approach these ideas. (GA)

The article offers seven basic hypotheses regarding the nature of the perceptual and cognitive underpinnings of stereotyping, and discusses the theoretical basis and empirical evidence for each. Subjects were 21 college students of mixed sex and race. (Author/MP)

Subjects aged 8, 10, 12, and 18 years participated in two visual search tasks. (Author/SB)

This study was designed to determine whether infants could perceive action role reversals when the direction of action is ruled out as a cue; whether infants consider inanimate, nonpotent objects to be unlikely agents; and whether both these discriminations could be reliably reflected in the heart rate response. (Author/SB)

Two studies explored the hypothesis that young children perceive integrally some stimuli that older children perceive separably. In both experiments, kindergarten, second- and fifth-grade children were required to classify sets of stimuli that varied in size and brightness. (SB)

The development of elementary school children's graphic representations of the large-scale environment in the context of the development of spatial cognition, especially Piagetian theory, is examined. The nature of children's graphic representations of space is reviewed and examined relative to development of their spatial cognition. (BT)
