Lexical processing in children and adults during word copying

Copying text may seem trivial, but the task itself is psychologically complex. It involves a series of sequential visual and cognitive processes, which must be co-ordinated; these include visual encoding, mental representation and written production. To investigate the time course of word processing during copying, we recorded eye movements of adults and children as they hand-copied isolated words presented on a classroom board. Longer and lower frequency words extended adults' encoding durations, suggesting whole word encoding. Only children's short word encoding was extended by lower frequency. Though children spent more time encoding long words compared to short words, gaze durations for long words were extended similarly for high- and low-frequency words. This suggested that for long words children used partial word representations and encoded multiple sublexical units rather than single whole words. Piecemeal word representation underpinned copying longer words in children, but reliance on partial word representations was not shown in adult readers.     

Textual Appropriation in Engineering Master’s Theses: A Preliminary Study

In the thesis literature review, an engineering graduate student is expected to place original research in the context of previous work by other researchers. However, for some students, particularly those for whom English is a second language, the literature review may be a mixture of original writing and verbatim source text appropriated without quotations. Such problematic use of source material leaves students vulnerable to an accusation of plagiarism, which carries severe consequences. Is such textual appropriation common in engineering master’s writing? Furthermore, what, if anything, can be concluded when two texts have been found to have textual material in common? Do existing definitions of plagiarism provide a sufficient framework for determining if an instance of copying is transgressive or not? In a preliminary attempt to answer these questions, text strings from a random sample of 100 engineering master’s theses from the ProQuest Dissertations and Theses database were searched for appropriated verbatim source text using the Google search engine. The results suggest that textual borrowing may indeed be a common feature of the master’s engineering literature review, raising questions about the ability of graduate students to synthesize the literature. The study also illustrates the difficulties of making a determination of plagiarism based on simple textual similarity. A context-specific approach is recommended when dealing with any instance of apparent copying.     

Unrepresentativeness of studies on memory of verbal material

Blakar, R. M. Unrepresentativeness of studies on memory of verbal material. Scand. J. Psychol., 1973, 14, 9–11. -The dominant traditions in studying memory of verbal material are criticized for lack of representativeness in that the stimulus material is particularistic, "meaningless" or presented out of relevant contexts, and presented more than once. When 27 letters were arranged in three lists of nine trigrams as (1) nonsense syllables, (2) common Norwegian words, and (3) a meaningful sentence of these words, and presented once in this order to seven subjects, mean number of letters recalled was 10, 23, and 27, respectively, indicating that the traditional and still dominant methods of research strip memory of one of its most effective means: the rules for grasping and organizing meaning.     

Very long‐term recall and recognition of well‐learned material

Three experiments examined very long‐term verbatim memory (from 4 months to 28 years) for lengthy, complex material. Experiments 1 and 2 found that recall (12 and 20 months after the material was last accessed) was at or near ceiling for many participants, and was significantly higher than free‐choice recognition, with recognition failure for recallable words (RF) being observed. The magnitude of the effect corresponded to that predicted by the Tulving–Wiseman ( 1975 ) function. Experiment 3 found that recall was at or near ceiling for 3 years, then declined dramatically as the retention interval increased. However, given equal amounts of context as retrieval cues, forced‐choice recognition remained relatively strong for as long as 28 years. These findings provide evidence of long‐term memory for exact details of complex discourse far in excess of previous demonstrations, and, under certain circumstances, extend the RF phenomenon to lengthy, well‐learned texts over long retention intervals.

Repetition blindness: The effects of stimulus modality and spatial displacement

Repetition blindness (Kanwisher, 1986, 1987) is the failure to detect repetitions of words in lists presented in rapid serial visual presentation (RSVP). Two questions were investigated in the present study. First, if repetition blindness is not found with auditory presentation, it would support a specifically visual account of the effect. Second, if displacement of the two instances in visual space eliminates repetition blindness, it would suggest that repetition blindness is restricted to instances in which identical stimuli are distinguished soley by temporal differences. In Experiment 1, the subjects omitted second occurrences of repeated words in verbatim recall of rapid sentences presented visually (in RSVP), but not auditorily (using compressed speech), indicating that repetition blindness is a modality-specific phenomenon. In Experiments 2 and 3, repetition blindness was observed even when two occurrences of a written word were presented in different locations, showing that distinct locations do not guarantee token individuation. The results are discussed within a model that distinguishes between processes of type recognition and token individuation.     

Effects of models and demonstrations of personal narratives on the use of lexical ties by writers with mental retardation

A single subject reversal design was used to investigate the effects of two methods for teaching writing to eight adolescents with mild or moderate mental retardation during a weekly process writing workshop. During each workshop, each student wrote a personal narrative while the teacher circulated among the group and provided positive verbal feedback and spelled words on request. Students' texts were later typed with corrected spelling and punctuation and returned to them with verbal praise before the next writing workshop. During the first experimental condition, the subjects listened to an exemplar text selected by the teacher. In the second phase, the teacher read a narrative she had written as the exemplar text. During the third experimental condition, the teacher orally self-instructed herself through steps in writing a narrative. The subjects' texts were analyzed for number of words written and number and type of lexical ties used to produce cohesion between sentences in a text. The model narrative produced the best gains in the number of words written by the poorer readers, while the demonstration improved the cohesiveness of their texts. The better readers and writers wrote more cohesively during the model narrative and produced longer text during the demonstration condition.     

Gender Differences in the Verbal Expression of Love Schema

This study attempts to supplement the investigations concerning the expression of narrative schema of love. The research question refers to the differences in the expression of narrative schema of love between men and women. A sample group of 100 Polish adults (50 men and 50 women) of average educational levels described their reaction to a photograph of a couple hugging each other. The narrative discourses about love, in terms of the syntactic, lexical, and formal elements, were compared. The results show that there were differences between the love schema produced by men and women—the latter using significantly more emotional words in their narrative than men. The narratives written by women were almost twice as long as those written by men.     

Selective impairment of the graphemic buffer in acquired dysgraphia: a case study

The case of an Italian dysgraphic patient (S.E.), who showed a deficit of both written and oral spelling capacities, without significant differences between words and nonwords, is reported. The pattern of the patient's performance was identical on writing to dictation, delayed copying, and written naming. The most common category of errors was single-letter deletions, and errors were predominantly made in medial positions. Stimulus length appeared to be the single factor that most affected performance. This pattern is consistent with the hypothesis that S.E.'s spelling disorder results from selective damage of the Graphemic Buffer. The case is discussed in relation to current functional models of writing and is compared with similar cases reported previously.     

How fuzzy-trace theory predicts true and false memories for words,sentences, and narratives

Fuzzy-trace theory posits independent verbatim and gist memory processes, a distinction that has implications for such applied topics as eyewitness testimony. This distinction between precise, literal verbatim memory and meaning-based, intuitive gist accounts for memory paradoxes including dissociations between true and false memory, false memories outlasting true memories, and developmental increases in false memory. We provide an overview of fuzzy-trace theory, and, using mathematical modeling, also present results demonstrating verbatim and gist memory in true and false recognition of narrative sentences and inferences. Results supported fuzzy-trace theory's dual-process view of memory: verbatim memory was relied on to reject meaning-consistent, but unpresented, sentences (via recollection rejection). However, verbatim memory was often not retrieved, and gist memory supported acceptance of these sentences (via similarity judgment and phantom recollection). Thus, mathematical models of words can be extended to explain memory for complex stimuli, such as narratives, the kind of memory interrogated in law.     

Source variability and recall of auditory material

Recall of auditory narrative material was measured under three conditions of presentation. These were a single source condition with material from one speaker, a four source fired sequence condition with material from four speakers in a fired sequence of 3-sec. lengths, and a four source random condition with material from four speakers in a random sequence of 3-sec. lengths. Recall was better for the single source condition than for the four source conditions. No significant difference was found between the fixed and random sequential presentations. Results are discussed in terms of the attentional behaviors involved in the tasks.     

Source variability and recall of auditory material 1

Recall of auditory narrative material was measured under three conditions of presentation. These were a single source condition with material from one speaker, a four source fixed sequence condition with material from four speakers in a fixed sequence of 3-sec. lengths, and a four source random condition with material from four speakers in a random sequence of 3-sec. lengths. Recall was better for the single source condition than for the four source conditions. No significant difference was found between the fixed and random sequential presentations. Results are discussed in terms of the attentional behaviors involved in the tasks.     

A fuzzy trace analysis of categorical inferences and instantial associations as a function of retention interval

Two experiments on children's inferences and associative memory provided a test of predictions from fuzzy-trace theory. Specifically, it was expected that gist-based false recognitions would increase with age and that false recognitions would be uncorrelated with verbatim memory. In Experiment 1, children in Grades 1 through 5 heard lists of category labels, clustered instances from categories, and individual instances. On an immediate test, children indicated whether or not they had previously heard a series of individually presented test words. This list consisted of old words, new words, or words that were categorically or semantically related to the studied word clusters. Children made more false recognition errors for instances than for categories. Verbatim memory and inferences were unrelated. In Experiment 2, the effect of a test delay on categorical inferences and associated instances was examined with children in Grades 1 to 6. With delay, false recognition of associated instances declined for children at all grade levels. In contrast, categorical inferences increased with delay for older children. Verbatim memory and inferences were uncorrelated under immediate and 1-day delay conditions, but there were some low but significant correlations across grades under the 7-day delay. The results of the two experiments are interpreted as supporting fuzzy-trace theory.     

Diaries of significant events: socio-linguistic correlates of therapeutic outcomes in patients with addiction problems

The principles of narrative therapy imply that autobiographical diaries written by patients in treatment will not only facilitate but also elucidate progress. The relationship between the linguistic content of diaries and progress in treatment was examined in this study. Complete sets of daily diaries of ‘significant events’ written by 16 patients receiving treatment for drug, alcohol and food addictions at a residential centre, using the 12-step approach of the Anonymous fellowships, were typed up for analysis. Three forms of socio-linguistic enquiry were employed: narrative characterization; evaluative statement coding and computer analysis of word strategies. Results indicated that success in treatment as rated by counselling and psychiatric staff was associated with the following characteristics of diary narratives. They are (a) focused on individual progress, whether adopting a ‘positive interpretative’ or ‘negative reactive’ style; (b) less critical of self over time and more positive about others external to the treatment centre; (c) both positive about the treatment programme and critical of self; (d) using words indicative of ‘insight’ and ‘negativity’ as assessed by Pennebaker's LIWC programme. It is concluded that autobiographical material can usefully be employed to assess progress in treatment, and that its intrinsic value in effecting change should be further explored. © 1997 John Wiley & Sons, Ltd.     

Familiarity and word recognition

Word recognition was examined for physics and non-physics students after a single visual presentation of a series of sixty words. Physics words likely to be familiar only to physics subjects were used to vary the prior familiarity of the two groups with the inspection material and the ratio of physics to common words (salience) was varied for each of the three inspection series. Common words, which were expected to have greater salience than physics words in one of the inspection series, were not found to be recognized better than the control pairings of physics words by either group of subjects. The absence of differences between physics and non-physics students in the number of inspection list words (positive instances) correctly identified supports the view that prior familiarity is not a critical variable when all inspection items are presented in a recognition test. Physics students made fewer errors than non-physics students in identifying both physics and common words in the the recognition test which were not in an inspection series (negative instances). It is suggested that the correct identification of negative instances involves a scanning of a subject's “internal store” of previously experienced inspection items and that this is more efficient when the meaning of all the items in this “store” is known.     

An analysis of writing in a case of deep dyslexia

In tests of her ability to produce written and spoken language, this deep dyslexic patient produced semantic, visual, and derivational errors, including functor substitutions, and exhibited part-of-speech and abstractness effects in oral reading, oral and written naming, and writing to dictation, but not in repetition of single words and copying from memory. This patient therefore provides confirmation of the hypothesis presented in Nolan and Caramazza (1982) that the defining symptoms of deep dyslexia will be observed in responses to any task which requires lexical mediation. The patient's written responses in all tasks but direct copying were characterized by spelling errors which included transpositions, omissions, substitutions, and additions of letters. A model of writing is proposed which explains these errors in terms of a disruption of a phoneme-grapheme conversion process which normally functions to prevent decay of information from a Graphemic Buffer.     

Recollection rejection of false narrative statements

Our research was focused on a false-memory editing operation that is posited in fuzzy-trace theory-recollection rejection. The main objectives were (a) to extend model-based measurement of this operation to a narrative task that ought to ensure high levels of recollection rejection and (b) to study five manipulations that ought to influence recollection rejection by affecting the accessibility of verbatim traces of narrative statements: recency of narrative presentation, narrative repetition, type of false-memory item, testing delay, and repeated testing. The results showed that the narrative task did indeed yield high levels of recollection, with an estimated 49% of gist-consistent distractors being rejected in this way on initial memory tests. Consistent with current theoretical conceptions of false-memory editing, the results also showed that recollection rejection increased as a function of manipulations that should enhance the accessibility of verbatim traces of narrative statements, with repeated testing delivering especially large increases in verbatim accessibility.     

Effects of Self-graphing on Written Expression of Fourth Grade Students with High-Incidence Disabilities

The purpose of this study was to determine the effects of self-graphing on the writing of 3 fourth grade students with high-incidence disabilities. Measures of written expression included total number of words written and number of correct word sequences. During intervention, students self-graphed their total number of words written in response to a timed story starter. A functional relationship was found between the self-graphing intervention and the total words written and number of correct word sequences. Implications for future research and practice are discussed.     

Curriculum-based measures of writing across grade levels

This study compared the technical adequacy of curriculum-based measures in written expression across diverse grade levels. Students (n = 484) completed two narrative writing samples in response to story starters. Samples were scored for the number of words written (TW), the number of correct word sequences (CWS), and the number of correct minus incorrect word sequences (CWS-ICWS). Alternate-form reliability and criterion-related validity coefficients of the curriculum-based measures were examined to determine differences between the coefficients according to grade level.Results indicated moderate to strong alternate-form reliability coefficients and variable criterion-related validity coefficients. The data from this study support the need for curriculum-based measures of writing to become more complex as students age and become more skilled.
