The boundary between two neighboring rings is called the fusion lines, which is enclosed by external segments called arcs. In the code, the separation of fusion line(s) from arcs takes place in such a way that proper matching is achieved. By this procedure, the structure of a compound is recreated. (Author)

A Teletype Model 37 machine has been modified for the coding of chemical structures. The coding rate of this model is higher than that of other machines of this type. The rationale for choosing this particupar type of input equipment is presented. (6 references) (Author/SM)

Three experiments are reported that were designed to delineate the properties of the stimulus encoding stage in reaction time tasks of varying stimulus-response compatibility. (Editor)

These experiments attempts to confirm the selective encoding processes thought to underlie orienting tasks and to shed some light on the empirical discrepancy as to whether semantic encoding inhibits or facilitates recognition performance in general, and the identification of distractor items in particular.

An experiment was designed to examine the contribution of phonetic information in the processing of words in tachistoscopic recognition masking. (Editor)

A SUBJECT HEADING AUTHORITY LIST CONTAINING MAIN ENTRIES, SCOPE NOTES, CROSS-REFERENCES, AND SUBDIVISIONS IS COMPILED, PRINTED, AND UPDATED BY COMPUTER. DESIGN CRITERIA, PROGRAMING, INPUT PREPARATION, PRINTING, AND FUTURE REFINEMENTS OF THE LIST TECHNIQUE ARE COVERED. A UNIQUE CODE WAS DESIGNED FOR SEQUENCING THE MASTER TAPE FILE AND PREPARING…

The effects of real-world schemata on recognition of complex pictures were studied. Two kinds of pictures were used: pictures of objects forming real-world scenes and unorganized collections of the same objects. (Editor)

Two contrasting views of the form and structure of knowledge are discussed -- an audiovisual model vs a computer tape library. The importance of two distinct psychological systems to represent language and knowledge of the world is stressed. (AM)

An introduction to the classification principles for documents at the Non-Formal Education Information Center is given for the cataloger. The classification scheme, itemized in the first section, consists of 11 main categories such as concepts, training methods, program content, bibliographies, and countries. The next section details…

Responses from 1,613 former servicemen with Spanish surnames were examined to evaluate Spanish surname recognition as a means of identifying persons of Latin American birth or ancestry. Questionnaires were mailed to 5,019 servicemen who had: (1) been inductees or enlistees in the Army, Navy, or Marine Corps; (2) left active duty in the first 6…

The chemical coding scheme of the Medical Coding Scheme (MCS), developed for use in the Comparative Systems Laboratory (CSL), is outlined and evaluated in this report. The chemical coding scheme provides a classification scheme and encoding method for drugs and chemical terms. Using the scheme complicated chemical structures may be expressed…

The results of various computerized coding techniques used to identify persons of Spanish derivation were compared to questionnaire responses in which people identified themselves as Spanish. The coding techniques classified names as Spanish and non-Spanish using the following: census surnames; Morton surnames; "Broad" Spanish surnames; "Narrow"…

This series of experiments was designed to evaluate a model of picture and word encoding. The primary assumptions are that both sensory and semantic codes can be activated for both pictures and words but the relative order of access to phonemic information is different for the two types of representation. (Editor/RK)

Three experiments were performed to determine if the use of an organizational strategy influenced free-recall performance more than did the degree of semantic elaboration. (Editor)

Proposes that a levels-of-processing analysis of encoding implies that (a) other things being equal, (e.g., task requirements), deeper information should be equally derivable from pictures and words; but (b) when picture-word differences do occur, they are encoding phenomena which result because task requirements generally favor more discriminable…
