Raymond Bertram; Jukka Hyönä; Matti Laine The role of context in morphological processing: Evidence from Finnish Journal Article In: Language and Cognitive Processes, vol. 15, no. 4/5, pp. 367–388, 2000. @article{Bertram2000, This paper is concernedwith the role of context on the processing of in?ected nouns inFinnish. Identi?cation of partitive plurals with the homonymic suf?x -jA was studied by presenting the target nouns in a sentence context and by recording durations of readers' eye ?xations and self-paced reading times for these targets. A recent visual lexical decision study indicated that the same in?ected words with -jA were sensitive to surface frequency manipulations, but not to base frequency manipulations. The authors interpreted these results to suggest that these in?ectional forms are stored and processed by means of their whole-word representations. In contrast, the present context study shows both a surface frequency effect and a lagged base frequency effect. We argue that syntactic cues prior to the target word prime the in?ectional reading of the -jA suf?x, and as a consequence the base is reinstated as an effective unit in processing these nouns with a homonymic suf?x.

Zenzi M. Griffin; Kathryn Bock What the eyes say about speaking Journal Article In: Psychological Science, vol. 11, no. 4, pp. 274–279, 2000. @article{Griffin2000, To study the time course of sentence formulation, we monitored the eye movements of speakers as they described simple events. The similarity between speakers' initial eye movements and those ofobservers performing a nonverbal event-comprehension task suggested that response-relevant information was rapidly extracted from scenes, allowing speakers to select grammatical subjects based on comprehended events rather than salience. When speaking extem- poraneously, speakers began fixating pictured elements less than a second before naming them within their descriptions, a finding con- sistent with incremental lexical encoding. Eye movements anticipated the order of mention despite changes in picture orientation, in who- did-what-to-whom, and in sentence structure. The results support Wundt's theory of sentence production.

Avital Deutsch; Ram Frost; Alexander Pollatsek; Keith Rayner Early morphological effects in word recognition in Hebrew: Evidence from parafoveal preview benefit Journal Article In: Language and Cognitive Processes, vol. 15, no. 4-5, pp. 487–506, 2000. @article{Deutsch2000, Hebrew words are composed of two interwoven morphemes: a triconso- nantal root and a word pattern. Two experiments examined the effect of the root morpheme on word identi?cation by assessing parafoveal preview bene?t effects.Although the information of the previewwas not consciously perceived, preview of the root's letters facilitated both naming and lexical decisions of target words derived from these roots. These results converge with previous results in Hebrew using the masked priming paradigm, suggesting that morphological units mediate early stages of word identification in Hebrew. |
Alexander Pollatsek; Jukka Hyönä; Raymond Bertram The role of morphological constituents in Reading finnish compound words Journal Article In: Journal of Experimental Psychology: Human Perception and Performance, vol. 26, no. 2, pp. 820–833, 2000. @article{Pollatsek2000, 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. |

Avital Deutsch; Keith Rayner Initial fixation location effects in reading Hebrew words Journal Article In: Language and Cognitive Processes, vol. 14, no. 4, pp. 393–421, 1999. @article{Deutsch1999, Three experiments examined initial fixation position effects for Hebrew readers. In English, the preferred viewing location (where readers' eyes initially land in a word) is to the left of the centre of words, and words presented in isolation are identified more easily when the initial fixation point is near the optimal viewing location (close to the centre of the word). In Experiment 1, we found that the preferred viewing location for Hebrew readers was to the right of the centre of words and that it was notmodulated by infectional morphological constraints. However, the results from the word identification task in Experiments 2 and 3 indicated that derivational morphological constraints do modulate the optimal viewing location. |
Gerry T. M. Altmann; Yuki Kamide Incremental interpretation at verbs: Restricting the domain of subsequent reference Journal Article In: Cognition, vol. 73, no. 3, pp. 247–264, 1999. @article{Altmann1999, Participants' eye movements were recorded as they inspected a semi-realistic visual scene showing a boy, a cake, and various distractor objects. Whilst viewing this scene, they heard sentences such as 'the boy will move the cake' or 'the boy will eat the cake'. The cake was the only edible object portrayed in the scene. In each of two experiments, the onset of saccadic eye movements to the target object (the cake) was significantly later in the move condition than in the eat condition; saccades to the target were launched after the onset of the spoken word cake in the move condition, but before its onset in the eat condition. The results suggest that information at the verb can be used to restrict the domain within the context to which subsequent reference will be made by the (as yet unencountered) post-verbal grammatical object. The data support a hypothesis in which sentence processing is driven by the predictive relationships between verbs, their syntactic arguments, and the real-world contexts in which they occur. |
Kin Fai Ellick Wong; Hsuan-Chih Chen Orthographic and phonological processing in reading Chinese: Evidence from eye fixations Journal Article In: Language and Cognitive Processes, vol. 14, no. 5-6, pp. 461–480, 1999. @article{Wong1999, The use of orthographic and phonologic information in reading Chinese text was investigated using an eye-monitoring technique. The basic manipulation was to change a critical character in a short passage so that various combinations of orthographic and phonological information were altered. Patterns of disruption caused by different manipulations were compared in order to reveal the use of orthographic and phonological information from individual characters during reading for comprehension. Results showed that orthographic manipulations produced reliable and early disruption in first fixation duration at the target word position. In contrast, phonological effects were only found in the measure of a relatively late stage of processing (i.e., total reading time) at the target position, but not in early measures of processing. These results supported the position that it is orthography rather than phonology, which plays an early and dominant role in reading Chinese. |

Antje S. Meyer; Astrid M. Sleiderink; Willem J. M. Levelt Viewing and naming objects: Eye movements during noun phrase production Antje Journal Article In: Cognition, vol. 6, no. 3, pp. B25–B33, 1998. @article{Meyer1998, Eye movements have been shown to reflect word recognition and language comprehension processes occurring during reading and auditory language comprehension. The present study examines whether the eye movements speakers make during object naming similarly reflect speech planning processes. In Experiment 1, speakers named object pairs saying, for instance, ‘scooter and hat'. The objects were presented as ordinary line drawings or with partly deleted contours and had high or low frequency names. Contour type and frequency both significantly affected the mean naming latencies and the mean time spent looking at the objects. The frequency effects disappeared in Experiment 2, in which the participants categorized the objects instead of naming them. This suggests that the frequency effects of Experiment 1 arose during lexical retrieval. We conclude that eye movements during object naming indeed reflect linguistic planning processes and that the speakers' decision to move their eyes from one object to the next is contingent upon the retrieval of the phonological form of the object names. |
Jukka Hyönä; Alexander Pollatsek Reading Finnish compound words: Eye fixations are affected by component morphemes Journal Article In: Journal of Experimental Psychology: Human Perception and Performance, vol. 24, no. 6, pp. 1612–1627, 1998. @article{Hyoenae1998, The role of morphemic processing in reading was investigated in 2 experiments in which participants read sentences as their eye movements were monitored. The target words were 2-morpheme Finnish compound words. In Experiment 1, the length of the component morphemes was varied and word length was held constant, and in Experiment 2, the uniqueness of the initial morpheme was varied and the rated familiarity and length of the word were held constant. The length of the initial morpheme influenced the location of the second fixation on the target word and the pattern of fixation durations (although it had a negligible influence on the gaze duration of the word). The frequency of the initial morpheme influenced the duration of the first fixation on the target word, had a substantial effect on the gaze duration, and also influenced the location of the first and second fixations on the target word. Subsidiary analyses indicated that these effects were unlikely to stem from orthographic factors such as bigram frequency. |

Dino Chincotta; Jukka Hyönä; Geoffrey Underwood Eye fixations, speech rate and bilingual digit span: Numeral reading indexes fluency not word length Journal Article In: Acta Psychologica, vol. 97, no. 3, pp. 253–275, 1997. @article{Chincotta1997, The present study examined whether the reading of language-neutral stimuli, as numerals are, at maximal speed by bilinguals indexes processes related to fluency rather than differences in articulation time between languages. We tested two groups of bilinguals that spoke the same languages (Finnish and Swedish) but whose mother tongues were different and obtained measures of Arabic numeral processing by monitoring eye movements. These measures were contrasted with articulation and numeral reading estimates of word length. The results indicated that Finnish- and Swedish-dominant bilinguals had shorter gaze durations and shorter reading times in their respective dominant languages, whereas both groups articulated digits faster in Swedish than Finnish. The Swedish-dominant group had a larger digit span in Swedish, whereas digit span was marginally greater in Finnish than Swedish for the Finnish-dominant group. The finding that numeral reading was influenced by cognitive loads independent of articulation, thus, moderated the view that bilingual digit span effects are mediated exclusively by variation in word length between languages. |
