Attention constraints of semantic activation during visual word recognition.

The reduction of semantic priming following letter search of the prime suggests that semantic activation can be blocked if attention is allocated to the letter level during word processing. Is this true even for the very fast-acting component of semantic activation? To test this, the authors explored semantic priming of lexical decision at stimulus onset asynchronies (SOAs) of either 200 or 1,000 ms. Following semantic prime processing, priming occurred at both SOAs. In contrast, no priming occurred at the long SOA following letter-level processing. Of greatest interest, at the short SOA there was priming following the less demanding consonant/vowel task but not following the more attention-demanding letter search task. Hence, semantic activation can occur even when attention is directed to the letter level, provided there are sufficient resources to support this activation. The authors conclude that the default setting during word recognition is for fast-acting activation of the semantic system.

Conquering technophobia: preparing faculty for today.

The constantly changing world of technology creates excitement and an obligation for faculty of schools of nursing to address computer literacy in the curricula at all levels. The initial step in the process of meeting the goals was to assist the faculty in becoming computer literate so that they could foster and encourage the same in the students. The implementation of The Cure for Technophobia included basic and advanced computer skills designed to assist the faculty in becoming comfortable and competent computer users. The applications addressed included: introduction to windows, electronic mail, word processing, presentation and database applications, library on-line searches of literature databases, introduction to internet browsers and a computerized testing program. Efforts were made to overcome barriers to computer literacy and promote the learning process. Familiar, competent, computer literate individuals were used to conduct the classes to accomplish this goal.

Assessment of the current computer literacy and future computer needs of emergency medicine residents and faculty.

The purpose of this study was to assess the current computer literacy and future computer needs of emergency medicine residents and faculty to aid in developing a computer literacy curriculum. All emergency medicine residents and full-time faculty from a random sample of emergency medicine residencies were mailed questionnaires assessing current computer familiarity and future computer needs. Twenty-one residencies were surveyed; 15 resident and 17 faculty questionnaires were returned. Thirty-seven percent (116 of 314) faculty and 29% (135 of 470) resident questionnaires were completed and returned. Eighty percent (12 of 15) of residencies had a designated computer for resident use; 93% (14 of 15) had a computer for use in the emergency department. Forty-seven percent of residents owned their own computer; 68% of faculty had a computer in their home, and 52% had computers in their office. Less than 30% of residents and faculty had formal computer training. Residents and faculty rated the current familiarity and future needs for various software applications on a five-point scale. Data were analyzed using the Wilcoxon-Rank Sum Test. Residents and faculty had the most anticipated need for word processing, graphics, literature searching, data base, and patient management programs. Future computer need was rated significantly higher than current computer familiarity in all computer application areas (P < or = .0002). It seems that emergency medicine residents and faculty have adequate access to computers, but minimal computer training. Residents and faculty have a high anticipated need for various basic computer applications.(ABSTRACT TRUNCATED AT 250 WORDS)

Current trends with natural language processing.

Natural Language Processing in the medical domain becomes more and more powerful, efficient, and ready to be used in daily practice. The needs for such tools are enormous in the medical field, due to the vast amount of written texts for medical records. In the authors' point of view, the Electronic Patient Record (EPR) is achieved neither with Information Systems of all kinds nor with commercially available word processing systems. Natural Language Processing (NLP) is one dimension of the EPR, as well as Image Processing and Decision Support Systems. Analysis of medical texts to facilitate indexing and retrieval is well known. The need for a generation tool is to produce progress notes from menu driven systems. The computer systems of tomorrow cannot miss any single dimension. Since 1988, we've been developing an NLP system; it is supported by the European program AIM (Advanced Informatics in Medicine) within the GALEN and HELIOS consortium and the CERS (Commission d'Encouragement á la Recherche Scientifique) in Switzerland. The main directions of development are: a medical language analyzer, a language generator, a query processor, and dictionary building tools to support the Medical Linguistic Knowledge Base (MLKB). The knowledge representation schema is essentially based on Sowa's conceptual graphs, and the MLKB is multilingual from its design phase; it currently incorporates the English and the French languages; it will also continue using German. The goal of this demonstration is to provide evidence of what exists today, what will be soon available, and what is planned for the long term. Complete sentences will be processed in real time, and the browsing capabilities of the MLKB will be exercised. In particular, the following features will be presented: Analysis of complete sentences with verbs and relatives, as extracted from clinical narratives, with special attention to the method of "proximity processing" as developed in our group and the rule based approach to language description to resolve the specific surface language problems as well as the language independent semantic situations. Comparison of results for English, French, and German sentences, showing the commonalities between these languages and, therefore, the re-usable features and the language specific aspects. Generation of noun phrases in English and French, showing the opportunities for translation between these two languages. Application of the analyzer to build a knowledge representation of ICD under the form of conceptual graphs and presentation of the possibilities of a natural language encoding of diagnosis. Strategies for query processing through a sample of abdominal ultrasonography reports, which have been analyzed and stored under the form of conceptual graphs. Feeding in and browsing of the Medical Linguistic Knowledge Base and other Dictionary Building Tools, using the perspective of an international initiative to converge towards a multilingual universal solution, valid for the medical domain. The demonstration platform is Microsoft Windows 4 on a PC, with Microsoft Visual Basic as the GUI and Quintus Prolog as NLP tools language. The same programs were originally developed for Unix-based workstations and are available on multiple platforms under Motif and X11. .

[Electronic data processing in urologic clinics. Results of a survey. Electronic Data Processing in Urology Group of the Graduate and Continuing Education Commission of German Urologists].

Computer equipment in Departments of Urology in Germany was evaluated by a nation-wide questionnaire. One hundred and fifty-three questionnaires were returned with detailed information on computer hardware, software and applications in Urology. Most departments were equipped with at least one computer. Computer equipment varied considerably among the participants including both stand alone personal computers (PCs) and local area networks (LANs) with several PCs connected by cable. Typically, PCs were IBM-compatible and ran the MS-DOS operating system Word processing and related applications were the most frequently mentioned computer tasks in urology. In some departments computers are also used in research for production of databases and graphics and for statistical applications. When computers were used for documentation of therapy and/or medical records, software was often custom-made according to the department's specific needs. In the future, more computers will be needed in departments of urology, because medical records will have to meet higher standards of documentation.

Alternatives in the handling, processing and storage of electrocardiograms.

Physicians and administrators are becoming aware that computer technology can play a significant role in the electrocardiology department. Problems related to the large number of requests for electrocardiograms, the production and communication of electrocardiographic tracings and reports, the access to stored tracings and the overall cost of providing effective services have led administrators to look for assistance through automation. Before expensive equipment and new procedures are introduced, a survey of the electrocardiology department's functions and procedures can lead to important insights. Automation can be achieved in stages, and problems can be solved by separate steps. Options range from basic word-processing support to completely automated electrocardiographic interpretation and computerized storage of records. Choosing the appropriate equipment and programs requires knowledge of the present system, awareness of the options and analysis of the costs and savings.

On the relationship between reading, listening and speaking: it's different for people's names.

Two experiments are reported that tested predictions derived from the framework of face, object, and word recognition proposed by Valentine, Brennen, and Brédart (1996). The findings were as follows: (1) Production of a celebrity's name in response to seeing the celebrity's face primed a subsequent familiarity decision to the celebrity's printed name. The degree of repetition priming observed was as great as that observed when a familiarity decision to the printed name was repeated in the prime and test phases of the experiment. (2) Making a familiarity decision to an auditory presentation of a celebrity's name primed a familiarity decision to the same celebrity's name presented visually. The magnitude of cross-modality priming was as great as the magnitude of within-modality repetition priming. This result for people's names contrasted with the effects observed in lexical decision tasks, in which no reliable cross-modality priming was observed. The results cannot be accounted for by previous models of face and name processing. They show a marked contrast between processing people's names and processing words. The results support the framework proposed by Valentine et al. (1996). The implications for models of speech production, perception, and reading are discussed, together with the potential of the methodology to elucidate our understanding of proper name processing.

Practical use of a word processor in a histopathology laboratory.

Some of the facilities available with a commercially purchased word processing program, linked to a DEC PDP 11/23 computer are described, together with an account of the practical histopathological use. The system is based on a share of the computer with a Clinical Chemistry Department. Development was time-consuming and required the constant availability of the Department of Physics. However, once working, considerable saving in secretarial time has resulted and a number of projects have been started which would not have been contemplated without the use of the word processor and its linked computer.

Microcomputer-based programs for the practicing vascular surgeon.

An inexpensive microcomputer system can be programmed in BASIC to provide convenient data storage, retrieval, and analysis for the practicing vascular surgeon. A personalized registry program permits input of key patient data that can be processed and retrieved in list form or groupings with operator control of variables. A second program, in which lower extremity revascularization procedures can be analyzed by various parameters, is described. Results can be obtained in life-table formats with comparative statistical analysis. For the private practitioner of vascular surgery, the use of various computer programs will allow management of information for self-assessment, record keeping, teaching, and publication with great accuracy and at significant cost savings. In addition, word processing can increase secretarial output and efficiency. Office management programs are available but need to be individually investigated to determine their use for a particular practice. The major advantages of the microcomputer for the practicing vascular surgeon are personal control and ready access to data that are easy to store, analyze, and retrieve.

Speech recognition training for enhancing written language generation by a traumatic brain injury survivor.

Impairments in motor functioning, language processing, and cognitive status may impact the written language performance of traumatic brain injury (TBI) survivors. One strategy to minimize the impact of these impairments is to use a speech recognition system. The purpose of this study was to explore the effect of mild dysarthria and mild cognitive-communication deficits secondary to TBI on a 19-year-old survivor's mastery and use of such a system-specifically, Dragon Naturally Speaking. Data included the % of the participant's words accurately perceived by the system over time, the participant's accuracy over time in using commands for navigation and error correction, and quantitative and qualitative changes in the participant's written texts generated with and without the use of the speech recognition system. Results showed that Dragon NaturallySpeaking was approximately 80% accurate in perceiving words spoken by the participant, and the participant quickly and easily mastered all navigation and error correction commands presented. Quantitatively, the participant produced a greater amount of text using traditional word processing and a standard keyboard than using the speech recognition system. Minimal qualitative differences appeared between writing samples. Discussion of factors that may have contributed to the obtained results and that may affect the generalization of the findings to other TBI survivors is provided.

When syntax meets semantics.

Three experiments concerning the processing of syntactic and semantic violations were conducted. Event-related potentials (ERPs) showed that semantic violations elicited an N400 response, whereas syntactic violations elicited two early negativities (150 and 350 ms) and a P600 response. No interaction between the semantic and early syntactic ERP effects was found. Sentence complexity and violation probability (25% vs. 75%) affected only the P600 and not the early negativities. The probability effect was taken as evidence that the P600 resembles the P3b. The temporal order of word processing in a sentence as suggested by the data was such that a more automatic syntactic analysis was performed (earlier syntactic-related negativities) in parallel with a semantic analysis (N400), after which a syntactic reanalysis was performed (P600). A reanalysis interpretation of the P600 could explain why the extent of the reanalysis differed with syntactic complexity and probability of ungrammaticality.

Developmental trends in the interaction between auditory and linguistic processing.

The developmental course of multidimensional speech processing was examined in 80 children between 3 and 6 years of age and in 60 adults between 20 and 86 years of age. Processing interactions were assessed with a speeded classification task (Garner, 1974a), which required the subjects to attend selectively to the voice dimension while ignoring the linguistic dimension, and vice versa. The children and adults exhibited both similarities and differences in the patterns of processing dependencies. For all ages, performance for each dimension was slower in the presence of variation in the irrelevant dimension; irrelevant variation in the voice dimension disrupted performance more than irrelevant variation in the linguistic dimension. Trends in the degree of interference, on the other hand, showed significant differences between dimensions as a function of age. Whereas the degree of interference for the voice-dimension-relevant did not show significant age-related change, the degree of interference for the word-dimension-relevant declined significantly with age in a linear as well as a quadratic manner. A major age-related change in the relation between dimensions was that word processing, relative to voice-gender processing, required significantly more time in the children than in the adults. Overall, the developmental course characterizing multidimensional speech processing evidenced more pronounced change when the linguistic dimension, rather than the voice dimension, was relevant.

Visual memory impairment in patients with obsessive-compulsive disorder: a controlled study.

Memory processes were compared in 26 patients presenting DSM-III-R obsessive-compulsive disorder (OCD) with 20 sex-, age- and education-matched normal controls. A significant between-group difference was found: visual memory was significantly lower in OCD, whereas no significant between-group differences in verbal memory were observed. A subsample of 17 OCD were also compared with the 20 control subjects on an explicit-memory free-recall task and an implicit-memory completion task using neutral, obsessive and guilt-responsibility words to test the effects of an emotional verbal input on memory functioning. No between-group difference was found, suggesting that emotionally laden word processing did not modify implicit and explicit memory performances.

[An experimental study of work load on VDT performance. Part 2. Effects of difference in input devices].

Effects of the difference in input device on work load of VDT task were studied. The subjects of the experiment were eight healthy male college students (age: 21-22 yr) having a binocular vision of not less than 0.7 and no astigmatism or hyperopia. The test consisted of an experimental word processing task in which the subjects visually searched e's in given sequences of alphabetical letters displayed on the CRT and converted them to 5's through input device operation. As for experimental conditions, two kinds of input devices, namely, keyboard and lightpen were adopted and 1 h was provided as each operation time. Critical flicker fusion (CFF), near point distance, accommodation time, subjective fatigue symptoms, blinking counts, pupillary reflex, electromyogram in upper limb, neck and shoulder and performance score were measured. The results were as follows. Decrease in C.F.F. was observed in two experimental conditions during the process of operating time. Increments in complaints of subjective fatigue related to visual function were seen in the two experimental conditions after 1 h VDT task. A higher error rate in performance was observed in the subjects using the lightpen compared to the one using the keyboard. The frequency of both blinking and pupil-size changes were lower in the subjects using the lightpen compared to those using the keyboard. This suggests that the gaze time of the VDT screen with lightpen-condition is longer than that in keyboard-condition.(ABSTRACT TRUNCATED AT 250 WORDS)

The role of morphological constituents in reading Finnish compound words.

The processing of transparent Finnish compound words was investigated in 2 experiments in which eye movements were recorded while sentences were read silently. The frequency of the second constituent had a large influence (95 ms) on gaze duration on the target words, but its influence was relatively late in processing: A clear effect only occurred on the probability of a third fixation. The frequency of the whole compound word had a similar influence on gaze duration (82 ms) and influenced eye movements at least as rapidly as did the frequency of the second constituent. These results, together with an earlier finding that the frequency of the first constituent affected the first fixation duration, indicate that the identification of these compound words involves parallel processing of both morphological constituents and whole-word representations.

Syntactic and semantic processing in the healthy and aphasic human brain.

A syntactic and a semantic task were performed by German-speaking healthy subjects and aphasics with lesions in the dominant left hemisphere. In both tasks, pictures of objects were presented that had to be classified by pressing buttons. The classification was into grammatical gender in the syntactic task (masculine or feminine gender?) and into semantic category in the semantic task (man- or nature made?). Behavioral data revealed a significant Group by Task interaction, with aphasics showing most pronounced problems with syntax. Brain event-related potentials 300-600 ms following picture onset showed different task-dependent laterality patterns in the two groups. In controls, the syntax task induced a left-lateralized negative ERP, whereas the semantic task produced more symmetric responses over the hemispheres. The opposite was the case in the patients, where, paradoxically, stronger laterality of physiological brain responses emerged in the semantic task than in the syntactic task. We interpret these data based on neuro-psycholinguistic models of word processing and current theories about the roles of the hemispheres in language recovery.

Electronic submission of academic works: a survey of current editorial practices of radiologic journals.

Computers are nearly ubiquitous in academic medicine, and authors create and compile much of their work in the electronic environment, yet the process of manuscript submission often fails to utilize the advantages of electronic communication. The purpose of this report is to review the submission policies of major academic journals in the field of radiology and assess current editorial practices relating to electronic submission of academic works. The authors surveyed 16 radiologic journals that are indexed in the Index Medicus and available in our medical center library. They compared the manuscript submission policies of these journals as outlined in recent issues of the journals and the corresponding worldwide web sites. The authors compared the journals on the following criteria: web site access to instructions; electronic submission of text, both with regard to initial submission and final submission of the approved document; text hardcopy requirements; word processing software restrictions; electronic submission of figures, figure hardcopy requirements; figure file format restrictions; and electronic submission media. Although the trend seems to be toward electronic submission, there currently is no clear-cut standard of practice. Because all of the journals that accept electronic documents also require a hardcopy, many of the advantages gained through electronic submission are nullified. In addition, many publishers only utilize electronic documents after a manuscript has been accepted, thus utilizing the benefits of digital information in the printing process but not in the actual submission and peer-review process.
