Pictures in sentences: understanding without words

To understand a sentence, the meanings of the words in the sentence must be retrieved and combined. Are these meanings represented within the language system (the lexical hypothesis) or are they represented in a general conceptual system that is not restricted to language (the conceptual hypothesis)? To evaluate these hypotheses, sentences were presented in which a pictured object replaced a word (rebus sentences). Previous research has shown that isolated pictures and words are processed equally rapidly in conceptual tasks, but that pictures are markedly slower than words in tasks requiring lexical access. The lexical hypothesis would therefore lead one to expect that rebus sentences will be relatively difficult, whereas the conceptual hypothesis would predict that rebus sentences would be rather easy. Sentences were shown using rapid serial visual presentation (RSVP) at a rate of 10 or 12 words per second. With one set of materials (Experiments 1 and 2), readers took longer to judge the plausibility of rebus sentences than all-word sentences, although the accuracy of judgment and of recall were similar for the two formats. With two new sets of materials (Experiments 3 and 5), rebus and all-word sentences were virtually equivalent except in one circumstance: when a picture replaced the noun in a familiar phrase such as seedless grapes. In contrast, when the task required overt naming of the rebus picture in a sentence context, latency to name the picture was markedly longer than to name the corresponding word, and the appropriateness of the sentence context affected picture naming but not word naming (Experiment 4). The results fail to support theories that place word meanings in a specialized lexical entry. Instead, the results suggest that the lexical representation of a noun or familiar noun phrase provides a pointer to a nonlinguistic conceptual system, and it is in that system that the meaning of a sentence is constructed.     

Bigram statistics for 205 five-letter words having single-solution anagrams

To assist research in anagram solving, this paper presents bigram statistics for 205 five-letter words known to form single-solution anagrams. Imagery, concreteness, age-of-acquisition, familiarity, and meaningfulness values for these words have previously been published. The bigram statistics presented here include the bigram rank and GTZERO measures recently devised and tested by Mendelsohn (1976).     

Acquisition of early words from single-word and sentential contexts

Toddlers 15 and 18 months of age were exposed to audiovisual recordings of two novel words paired with novel toys. The words were presented in familiar sentence frames or in isolation. Linguistic context had a greater effect on younger than on older infants. Specifically, 15-month-old boys exhibited successful learning only in the context of single words, and 15-month-old girls did so only for words presented in sentences. Older infants acquired the new words from both contexts, and they learned more rapidly than younger infants. Receptive and expressive vocabulary made no independent contribution to performance.     

The information conveyed by words in sentences

A method is presented for calculating the amount of information conveyed to a hearer by a speaker emitting a sentence generated by a probabilistic grammar known to both parties. The method applies the work of Grenander (1967) to the intermediate states of a top-down parser. This allows the uncertainty about structural ambiguity to be calculated at each point in a sentence. Subtracting these values at successive points gives the information conveyed by a word in a sentence. Word-by-word information conveyed is calculated for several small probabilistic grammars, and it is suggested that the number of bits conveyed per word is a determinant of reading times and other measures of cognitive load.     

Recognition of partial regularity in words and sentences

The involvement of morphological representations in reading Swedish and Dutch was explored using a lexical decision task and a sentence continuation task. In Experiment 1, letter strings were studied which were composed of a root and derivational suffix, a nonroot and suffix, a root and nonsuffix, or a nonroot and nonsuffix. Latencies in identifying nonword items increased as the letter strings became morphologically regular. In Experiment 2, subjects chose among pairs of continuations to a sentence. One choice offered at a given point was acceptable in context, while the other was acceptable, or contained an inappropriate stem, an inappropriate inflection, or both together. The latency to choose a correct continuation increased as the foil offered became morphologically appropriate. The results show that use of morphemic representations in reading as reported by Caramazza et al. (1988) extends from the identification of single morphs to the integration of information across phrases.     

Nonsense strings,words, and sentences: Some cross-linguistic comparisons

Summary Three experiments were carried out in which strings of 15 syllables were presented to native German speakers. Each S heard the same string 25 times. In Exp. I, the strings were nonsense stems with no structure, morphological structure, or morphological and syntactic structure characteristic of the English language. In Exp. II, the strings were either a random list of English words or a meaningful sentence. In Exp. III, the strings were either a random list of German words or a meaningful sentence. In all the experiments, the strings were either monotone or intonated. The results of Exp. I confirmed the finding of O'Connell, Turner, and Onuska (1968) that linguistic structure facilitates recall. Facilitation was limited to intonated versions and localized at the high structure level (morphology and syntax). The remaining experiments indicated that, in strings of actual lexical items, the relative facilitative influence of intonation and structure depends on the redundance of the linguistic cues. In all experiments, the rate of speech production by Ss approached that of spontaneous speech as a function of both structure and intonation in the stimulus string.

Zusammenfassung In 3 Experimenten wurden deutschsprachigen Vpn Ketten aus 15 Silben dargeboten. Jede Vp hörte dieselbe Kette 25mal. Die Ketten im ersten Experiment bestanden entweder aus sinnlosen Silben ohne jede Struktur, mit morphologischer Struktur oder mit morphologischer und syntaktischer Struktur. Alle Strukturmerkmale wurden der englischen Sprache entnommen. Die Ketten im zweiten Experiment stellten entweder eine Zufallsliste englischer Wörter oder einen sinnvollen Satz dar. Im dritten Experiment wurde eine Zufallsliste aus deutschen Wörtern oder ein sinnvoller Satz verwendet. In allen Experimenten wurden die Ketten entweder monoton oder intoniert dargeboten. Die Ergebnisse des ersten Experiments bestätigten den Befund von O'Connell, Turner, und Onuska (1968), daß die sprachliche Struktur zu einer Verbesserung der Wiedergabe führt. Diese Verbesserung trat nur bei der intonierten und hochstrukturierten Bedingung (Morphologie und Syntax) auf. Die übrigen Experimente zeigten, daß der Verbesserungseffekt von Intonation und Struktur in den Wortketten und Sätzen von den sprachlichen Cues abhängig ist. In allen Experimenten näherte sich die Sprechgeschwindigkeit der Vpn der Geschwindigkeit der spontanen Sprache als Funktion der Struktur und Intonation der Stimuluskette.

Eye movements during the handwriting of words: Individually and within sentences

Handwriting, a complex motor process involves the coordination of both the upper limb and visual system. The gaze behavior that occurs during the handwriting process is an area that has been little studied. This study investigated the eye-movements of adults during writing and reading tasks. Eye and handwriting movements were recorded for six different words over three different tasks. The results compared reading and handwriting the same words, a between condition comparison and a comparison between the two handwriting tasks. Compared to reading, participants produced more fixations during handwriting tasks and the average fixation durations were longer. When reading fixations were found to be mostly around the center of word, whereas fixations when writing appear to be made for each letter in a written word and were located around the base of letters and flowed in a left to right direction. Between the two writing tasks more fixations were made when words were written individually compared to within sentences, yet fixation durations were no different. Correlation of the number of fixations made to kinematic variables revealed that horizontal size and road length held a strong correlation with the number of fixations made by participants.     

Individual differences in ratings of words combined in sentences

To examine the efficiency of regression-compounded group means as predictors of individual ratings of words combined in sentences, a study by Heise (1969) was replicated and extended to obtain pre- and postcombination ratings from the same subjects. Heise's model efficiently predicted group ratings for words combined in sentences (R²=0.86), but neither group-weighted (R²=0.19) nor individually weighted (R²=0.28) regression equations efficiently predicted the rating of individual subjects. The findings are consistent with several findings that question the applicability of widely studied models of attitude change to individual differences and alternative approaches to this problem are discussed.     

Memory for emotional words in sentences: the importance of emotional contrast

Numerous researchers have demonstrated that emotional words are remembered better than neutral words. However, the effect has been attributed to factors other than emotion because it is somewhat fragile and influenced by variables such as the experimental designs employed. To investigate the role of emotion per se in memory for emotional words, negative-affect but low arousal emotional words were placed in sentence contexts that either activated high emotional meanings of the words (Shane died in his car last night.), or low emotional meanings of the words (Shane's old car died last night). The high-emotional contexts led to better memory than the low-emotional contexts, but only in mixed lists of emotional and neutral words. Additionally, the traditional emotional memory effect was also limited to mixed lists. The results are consistent with the idea that an emotional contrast is responsible for the emotional memory effect with low arousal emotional words.

On decision procedures for sentential logics

In Section 2 I give a criterion of decidability that can be applied to logics (i.e. Tarski consequence operators) without the finite model property. In Section 3 I study ukasiewicz-style refutation procedures as a method of obtaining decidability results.This method also proves to be more general than Harrop's criterion.     

Shedding light on words and sentences: near-infrared spectroscopy in language research

Investigating the neuronal network underlying language processing may contribute to a better understanding of how the brain masters this complex cognitive function with surprising ease and how language is acquired at a fast pace in infancy. Modern neuroimaging methods permit to visualize the evolvement and the function of the language network. The present paper focuses on a specific methodology, functional near-infrared spectroscopy (fNIRS), providing an overview over studies on auditory language processing and acquisition. The methodology detects oxygenation changes elicited by functional activation of the cerebral cortex. The main advantages for research on auditory language processing and its development during infancy are an undemanding application, the lack of instrumental noise, and its potential to simultaneously register electrophysiological responses. Also it constitutes an innovative approach for studying developmental issues in infants and children. The review will focus on studies on word and sentence processing including research in infants and adults.     

Clause boundaries and recognition latencies for words in sentences

In 35 sessions of 10 trials apiece, each of eight Ss viewed and judged a display which produced simultaneous brightness contrast. All Ss were given an instructional set toward realistic perception. Members of one subgroup were informed as to the magnitude of their judgments; members of another were not. For every S, there occurred highly significant changes in magnitude of simultaneous brightness contrast over time. There were wide individual differences in the nature of the changes, not all of which were decremental. No significant differences were found as between informed and noninformed groups. The results are viewed as giving limited support to the notion of learning in the perception of simultaneous brightness contrast.     

Understanding the meaning of words and sentences: The role of non-linguistic processes

This special issue on linguistic and non-linguistic processes in the comprehending of words and sentences represents the outcome of a three-day workshop at the University of Tübingen, Germany. The workshop focused on the contribution of non-linguistic processes in language comprehension and hence brought together researchers from the domains of linguistic and non-linguistic cognition.     

Interaction of stimulus and contextual information during reading: Identifying words within sentences

In general, studies on the effects of a sentence context on word identification have focused on how context affects the efficiency of processing a single target word, presented separately from the context. Such studies probably would be incapable of measuring contextual facilitation resulting from cascaded or parallel processing of neighboring words within a sentence. To measure these and other types of facilitation, we presented entire phrases and sentences for subjects to read as fast as possible and to monitor for nonwords. Subjects read at rates representative of natural reading. Experiment 1 demonstrated a large contextual facilitation effect on decision time. Experiment 2 showed that facilitation is caused by specific semantic information and, perhaps to a greater degree, by nonpredictive syntactic information. Experiment 3 showed that the amount of facilitation is greater than could be accounted for by separate contributions from autonomous word level and sentence level processes. These results present difficulties for an autonomous model of reading, but are consistent with interactive models, in which the results of ongoing sentential analyses are combined with stimulus information to identify words.     

Sounds, words, sentences: age-related changes across levels of language processing

Age-related changes in sensory, lexical, and sentence processing were examined and compared using event-related potentials (ERPs) recorded as young and elderly participants listened to natural speech for comprehension. Lexically associated and unassociated word pairs were embedded in meaningful or syntactically legal but meaningless sentences. Early, general sensory, and attention-related responses (N1, P2) were delayed by about 25 ms for older participants, but later components indexing semantic processing (N400) were not delayed. There were no differences in the size, timing, or distribution of lexical associative effects for the two groups. In contrast, message-level context effects were delayed by more than 200 ms in the elderly group. The results support models that posit age-related changes primarily in higher order language processes.
