This paper examines the developmental stages of haptic perception (the process of recognizing objects by the sense of touch alone), and attempts to clarify some conflicting results of studies of the effects of memory and object type. The paper also presents a specific study of haptic perception in 144 preschool and kindergarten children from…

The aim of this study is to investigate the effects of noise on the performance of simultaneous conference interpreters, and to carry out a detailed examination of verbal and temporal aspects of their output in relation to source language input. A further aim is to compare the relative effectiveness of simultaneous and consecutive interpretation…

A research project involving 16 experiments investigated the nature of the encoding process for verbal materials, particularly differences arising from mode of presentation. The results showed that a change in mode of presentation of items produced a recovery from interference in short term retention. Since intermodal interference was lower than…

ARIS is an artificial intelligence system which uses the English language to learn, understand, and communicate. The system attempts to simulate the psychoneurological processes which enable man to communicate verbally. It uses a modified stratificational grammar model and is being programed in PL/1 (a programing language) for an IBM 360/67…

Ninety students in grades six to eight listened to or read written passages and then identified and corrected grammar and syntax errors. Students listening and receiving auditory feedback located more errors than those reading. Learning-disabled students and students matched on reading level identified fewer errors than did students matched on…

A study of 12- to 14-year-olds was conducted to investigate which components of spatial ability may be dependent on general cognitive functioning level and to compare possible differences in carrying out certain spatial operations in children of equal intelligence, but who are not specifically gifted for mathematics or visual arts.

Investigates the effects of verbal and pictorial advance organizers on science text comprehension of children with high or low prior knowledge. Finds that verbal advance organizers assist text comprehension of children with strong prior knowledge, while the addition of a pictorial component aids comprehension of children with weak prior knowledge.…

The effects on compliance of two types of differential negative reinforcement (DNR) were studied with a five-year-old girl with moderate mental retardation and a history of severe disruption. Escape from instructional trials was either contingent on a communicative behavior or compliance. Behaviors improved with both interventions, but compliance…

This study of 78 prelingually deaf children (ages 6-13) who were educated orally found that children up to 9 years old seemed to process written words by means of visual codes. Older children tended to differentiate and preferred either a visual or speech-based strategy, with the latter associated with better reading performance. (Author/JDD)

This article describes the Descriptive Video Service (DVS), developed by WGBH-TV in Boston, Massachusetts, to provide narrated descriptions of the key visual elements of television programs without interfering with their audio or dialogue. The article discusses the history of DVS, broadcast tests, reactions to DVS, and the future of DVS.…

Despite the seminal studies of response differentiation by the method of successive approximation detailed in chapter 8 of "The Behavior of Organisms" (1938), B. F. Skinner never actually shaped an operant response by hand until a memorable incident of startling serendipity on the top floor of a flour mill in Minneapolis in 1943. That occasion…

From a co-operative education class in an urban high school, 16 adolescent males were identified as impulsive and as high-risk based on their performance on the Matching Familiar Figures test and the advice of teachers and counselors. Students participated in 12 to 15 videotaped group problem-solving sessions (20-25 minutes in length) over a…

Research indicates that people have two distinct information processing modalities, one for verbal material and one for nonverbal material. The nonverbal mode is used for visual images and is characterized by creative and relatively undisciplined associations. The verbal mode deals with abstract stimuli and is restrained by logic and the need to…

This study investigates the role of labeling in developmental increases in picture recall. In two experiments, the memory for pictorial paired-associates of first graders or second graders, fourth graders and adults was evaluated by means of a study-test cued recall procedure. In Experiment 1, the stimulus presentation duration (on-time) and the…

This study investigated the relative effectiveness of verbal and visual modes of presentation on the learning of paired-associates by 64 3-year-old and 64 8-year-old children. Nine pictorial paired-associates and 9 verbal paired-associates were formed from pictures or names of familiar objects. At each age level, 8 male and 8 female subjects were…
