The field-by-length effect in word processing: a failure to confirm.

It has been shown that the left hemisphere superiority for processing words applies only to long words by Young and Ellis (1985). These authors defined the length as the number of letters. Bruyer and Janlin (1989) compiled supporting evidence by contrasting the number of letters and the physical size of the stimuli: Short words were made as long as "long" words by the use of blank spaces between the letters. In the present study, another control was used: The physical size of the stimuli was manipulated by means of the viewing distance (nearer short words were as long as the long words). Thirty-six subjects were submitted to 720 trials in which two words appeared for 150 ms, one in each visual hemifield. The subject reported the two words in a defined order. The results did not clearly support the previous studies.

The locus of the effects of sentential-semantic context in spoken-word processing.

Models of word recognition differ with respect to where the effects of sentential-semantic context are to be located. Using a crossmodal priming technique, this research investigated the availability of lexical entries as a function of stimulus information and contextual constraint. To investigate the exact locus of the effects of sentential contexts, probes that were associatively related to contextually appropriate and inappropriate words were presented at various positions before and concurrent with the spoken word. The results show that sentential contexts do not preselect a set of contextually appropriate words before any sensory information about the spoken word is available. Moreover, during lexical access, defined here as the initial contact with lexical entries and their semantic and syntactic properties, both contextually appropriate and inappropriate words are activated. Contextual effects are located after lexical access, at a point in time during word processing where the sensory input by itself is still insufficiently informative to disambiguate between the activated entries. This suggests that sentential-semantic contexts have their effects during the process of selecting one of the activated candidates for recognition.

Capacity limitations in visual word processing.

The ability of subjects to process English words in a spatially parallel manner was examined in several redundant-target detection tasks. When redundant targets were identical in a given display, processing limitations were evident in a task that required subjects to make semantic categorizations of words. However, parallel processing of identical redundant target words was exhibited in a lexical decision task that required a structural analysis of letter strings, but not an analysis of word meaning. The difference in performance in the two tasks suggests that the capacity for semantic processing is limited. Analyses designed to examine whether the redundancy gain in Experiment 2 could be attributed to limited capacity processing in conjunction with positional preferences provided evidence against this possibility. In addition, these analyses suggested that the processing times for the redundant targets in Experiment 2 might be positively correlated. In the third and fourth experiments, the redundant-target displays contained two different words. Processing interference, in the form of a redundancy loss, was evident in the lexical decision task, but not in the semantic categorization task, confirming a difference in the mode of processing between the two tasks. The results provide evidence against the unlimited-capacity, parallel processing hypothesis of late selection theories of attention.

Word processing in the physician's office.

Although word processing has become an accepted business function for many office professionals, physicians have been slow to recognize the many uses that it has to offer. The physician's office can achieve greater productivity and efficiency by the integration of word processing into both the clerical and clinical sectors of medical practice. The task begins with an organization of professional communications and is developed based on the needs of an individual practice.

Acquisition of word-processing skills by younger, middle-age, and older adults.

A total of 45 subjects in three age groups (younger, middle-age, older) were trained to word process on microcomputers using a commercial training program and an experimenter-designed test and evaluation protocol. Although all of the subjects mastered the essentials of word processing, the older group took significantly longer to complete the training and evaluation procedures and performed more poorly on a review examination that tested their knowledge of the word-processing commands and techniques. The results are discussed in relation to requirements for trainer assistance, motivational factors, and the need to design training protocols that meet the needs of older adults.

Word-processing equipment for hospital pharmacy applications.

Experiences with the use of three word-processing machines in the pharmacy departments of two hospitals are reported. Criteria used in evaluating the equipment included keyboard design, disc storage capabilities, software practicality, print format options and security of data. The applications studied were label production, storage of personnel information, scheduling of repetitive tasks, and composition of drug bulletins and procedure manuals. The Wang System 10A was the least useful. The Lanier LTE-2S required the shortest training period for routine tasks. The IBM System 6/442 was the most flexible. Word-processing equipment may be used effectively in the hospital pharmacy department to handle time-consuming, repetitive tasks.

Standardization of electrocardiographic interpretive statements: a menu for word processing.

Standardization of electrocardiographic interpretive statements is a goal of various coding systems, but word processing has not usually been considered. A simple, easily memorized system for clinical electrocardiography has been developed and used for approximately 60 000 interpretations. It takes the form of a "menu", in which boxes stand for various interpretive statements; the boxes are identified by mnemonics and marked by the interpreter when appropriate. The results provide better standardization, significant decreases in the numbers of descriptive statements and words per interpretation and considerable saving in typing time. Acceptance by the interpreters has been good. Features of the system allow for word processing as part of a polarcardiography computing system.

Evidence for a parallel input serial analysis model of word processing.

A parallel input serial analysis (PISA) model of word processing was developed and tested. The goal was to expand on the "critical processing duration" hypothesis of Johnson, Allen, and Strand (1989) so that both single-word and multiple-word presentation, letter detection data could be explained. In Experiments 1-3 four different word frequency categories on a single-presentation, letter detection task were used. These three experiments indicated that there was a curvilinear relationship between word frequency and letter detection reaction time (RT). That is, letter detection RTs for medium-high-frequency words were significantly longer than letter detection RTs for very-high-, low-, and very-low-frequency words. These results support the PISA model rather than the Healy, Oliver, and McNamara (1987) version of the unitization model. In Experiments 4-5 multiple-presentation (i.e., two words), letter detection tasks were used. The PISA model could also account for the results from these two experiments, but the unitization model could not.

Word processing: its impact on children's writing.

This paper describes the effects of using a word processor on the creative writing of a small group of children with learning disabilities. Each week the children wrote one word-processed and one handwritten story. The effects of using a word processor seemed to be influenced by the particular problems the children were experiencing with written work. For the children with severe spelling problems, using a word processor seemed to result in fewer spelling errors, while for the children who were still predominantly concerned with the mechanics of the writing task, using a word processor seemed to result in longer stories.

[Auditory-visual Stroop interference in picture-word processing].

This study examined the features of cross-modal Stroop interference in picture-word processing by making comparison between auditory-visual and visual-visual tasks. Eleven subjects participated in each task and were instructed to name the picture as quickly as possible. To clarify the semantic-relatedness effect on the amount of interference, five types of different degrees of picture-word semantic relation were used: same stimulus (SS), same category (SC; both items belong to the same category), incongruent (IC), neutral (N) and control condition (C). To investigate the time course of information processing, stimulus onset asynchrony between the word and the picture were varied. In auditory-visual task strong interference effects were obtained in SC, IC and N conditions when the words preceded the pictures by 200,100 and 0 ms. In visual-visual task the similar effects were shown in SC and IC conditions within a 100 ms envelope around simultaneous onset of the two components. These results were discussed in relation to the locus of Stroop interference and the processing mechanisms of picture naming and word reading.

[Word processing of medical records and epicrises at a hospital department].

In January 1988 a pilot project was initiated at the Department of Neurology, University Hospital of Tromsø, to explore the possible use of word processing in routine operations of patient documentation. The project was evaluated at the end of ten months, and had resulted in a reduction of approximately 25% in the required written operations. Other notable results were reduced use of extra staff and overtime, and a general improvement in the staff's working conditions. The department's doctors reported no deterioration in the quality of the patient documentation produced using the new procedures. The successful outcome of the project was made possible by using the hospital's internal resources to develop suitable procedures for the instruction and supervision of the relevant staff, to install equipment, and to prepare a users' manual.

Orthography and familiarity effects in word processing.

Both orthographic regularity and visual familiarity have been implicated as contributors to the efficiency of processing visually presented words. Our studies sought to determine which of the internal codes representing words in the nervous system are facilitated by these two variables. To do this, sets of letter strings in which orthography and familiarity were factorially combined were used as the basis for physical, phonetic, semantic, and lexical judgments. The data indicated consistent effects of orthography on the activation of all codes. These effects were seen in same-different matching and in judgments of stimulus orientation, which are based on visual codes; in judgments of pronounceability based on phonetic codes; in judgments of meaningfulness based on semantic codes; and in lexical decisions, which are based on phonetic and semantic codes together. Familiarity, on the other hand, had a clear influence on the activation of semantic codes and to a lesser extent affected phonetic codes. Despite previous positive results found in matching letter strings, however, no influence of familiarity occurred in judgments based on visual codes once evidence for criterion shifting was eliminated. Our negative results included direct tests of facilitation in matching acronyms (e.g., FBI) and in matching both regular and irregular strings familiarized by specific training. It now appears that earlier findings of visual familiarity effects may be attributed to response biases resulting from the activation of higher level codes sensitive to familiarity, and to the use of small sets of training stimuli that allowed subjects to induce orthographic-like rules. The results obtained so far with our methods seem to reconcile an inconsistent literature by showing that speeded decisions based on visual codes are most strongly influenced by rule-governed processing mechanisms sensitive to orthographic structure, whereas decisions based on phonetic and semantic codes are affected about equally by rule-governed mechanisms and by stimulus-specific mechanisms sensitive to familiarity. This conclusion may lead to changes in notions of how effective various kinds of visual training are likely to be at different stages in the acquisition of reading skill.

Properties of neuronal activity in cortex and subcortical nuclei of the human brain during single-word processing.

Neuronal impulse activity (NIA) in different cortical areas, subcortical nuclei of the thalamus and striopallidum was recorded via depth electrodes in human patients as they performed a visual word recognition task. The properties of neuronal responsiveness were compared across regions. During single-word processing approximately 75-80% of the responsive cortical neurons were characterized by poststimulus inhibition of firing rate; an increased firing rate (i.e., excitatory response) was observed in about 20-25% of the responsive cortical neurons. Among the subcortical nuclei, mainly in the thalamus and striopallidum, more than 90% of the responsive neurons were characterized by poststimulus excitation; less than 10% exhibited poststimulus inhibition of firing rate.
