Four groups of infants, 4 1/2 to 5 1/2 months of age, were presented with repeated speech stimuli which were synthesized exemplars of the sound, "baba," natural exemplars of "baba" or "kaba," or novel syllables on each trial. (RH)

Reports the major findings of a study that investigated the effectiveness of using pictures of different art styles (stick figures, faceless outline drawings, detailed black-and-white, detailed black-and-white with watercolor wash, and black-and-white photographs) with 423 new readers in Papua New Guinea.

Subjects watched animated films depicting the simultaneous movements of two triangles toward a goal. One triangle was pushed by an external object while the other triangle was not. Initially, only college students understood the discounting principle. Kindergarten children, second graders, and fourth graders did not. Revision of the film produced…

Immediate recall measures on one or both types of stimuli were recorded under two conditions: (1) in which stimuli were close together and (2) in which they were separate. Results indicated that normal children selectively attended significantly better than LD children under Condition 1 but not in Condition 2, in which both groups were equal.…

To determine if the location or type of a picture affects reading comprehension, college students read a passage and then answered multiple-choice questions that assessed different types of incidental learning. Subjects who viewed a picture after reading the passage scored higher than those who viewed before reading. (Author/JEG)

The ability of 18-, 24-, and 30-week-old infants to learn conceptual categories regarding adult female faces was examined using a habituation paradigm. (JMB)

Examined acuity thresholds for 1- and 2-month-old infants by presenting square wave gratings in a preference paradigm at four viewing distances. (Author/JMB)

Image size, viewing angle, and contrast affect performance of a visual discrimination task. Further, the three factors interaction in their effect on performance. (Author)

Assessed 14-week-olds' attention to green or red target objects moving in a field of distracting objects that varied in color. Found that infants' detection of green moving targets was masked in the presence of mixed red and green objects. Masking was not observed for red targets or for green targets in a field of green objects. (BC)

Investigated simultaneous occurrence of emergent stimulus-response relations (functional equivalence) and stimulus-stimulus relations (stimulus equivalence). Trained 4- and 5-year olds to emit specified responses to pairs of stimuli in one setting (original training) and to emit other responses to one member of each pair in another setting…

Presents data from South African Sign Language (SASL) to exemplify the fact that sign languages are able to represent action or events from more than one perspective at the same time. Describes the different ways in which these multiple perspectives may be created and looks specifically at the role of classifier predicates in the creation of…

Extends the discussion of mimetic documents from labeled pictures and picture lists to labeled diagrams and diagram lists. Highlights how different mimetic documents provide qualitatively different levels of understanding. (RS)

Two experiments using event-related potentials (ERPs) investigated recognition memory in infants. ERPs were recorded to 100 identical aural stimuli. Fifty familiar and 50 novel stimuli were presented 24 hours later. Results suggest that establishment of memory trace involved a process by which responses to repeated events were more consistent when…

This study investigated the effect of auditory feedback alterations on stuttering frequency of 10 adults. At high speech rates, stuttering frequency was significantly reduced under delayed auditory feedback, frequency altered feedback, and a combination. There were no significant differences among the altered feedback conditions. (Author/SW)

Infants between four and eight months of age were tested for their ability to reach for visible and unseen toys that made sounds. Infants reached for toys in the dark under two auditory illusion conditions, the Haas effect and the midline illusion. Results indicated that, by four months of age, infants perceived the Haas effect and the midline…
