Prime Target

Using a lexical decision task in which two primes appeared simultaneously in the visual field for 150 msec followed by a target word, two experiments examined semantic priming from attended and unattended primes as a function of both the separation between the primes in the visual field and the prime-target stimulus-onset asynchrony (SOA). In the first experiment significant priming effects were found for both the attended and unattended prime words, though the effect was much greater for the attended words. In addition, and also for both attention conditions, priming showed a tendency to increase with increasing eccentricity (2.3°, 3.3°, and 4.3°) between the prime words in the visual field at the long (550 and 850 msec) but not at the short (250 msec) prime-target SOA. In the second experiment the prime stimuli were either two words (W-W) or one word and five Xs (W-X). We manipulated the degree of eccentricity (2° and 3.6°) between the prime stimuli and used a prime-target SOA of 850 msec. Again significant priming was found for both the attended and unattended words but only the W-W condition showed a decrement in priming as a function of the separation between the primes; this decrement came to produce negative priming for the unattended word at the narrow (2°) separation. These results are discussed in relation to the semantic processing of parafoveal words and the inhibitory effects of focused attention.

Abstract This article reports the results of an auditory lexical decision task, testing the processing of phonetic detail of English noun/verb conversion pairs. The article builds on recent findings showing that the frequent occurrence in certain prosodic environments may lead to the storage of prosody-induced phonetic detail as part of the lexical representation. To investigate this question with noun/verb conversion pairs, ambicategorical stimuli were used that exhibit systematic occurrence differences with regard to prosodic environment, as indicated by either a strong verb-bias, e.g., talk (N/V) or a strong noun-bias, e.g., voice (N/V). The auditory lexical decision task tests whether acoustic properties reflecting either the typical or the atypical prosodic environment impact the processing of recordings of the stimuli. In doing so assumptions about the storage of prosody-induced phonetic detail are tested that distinguish competing model architectures. The results are most straightforwardly accounted for within an abstractionist architecture, in which the acoustic signal is mapped onto a representation that is based on the canonical pronunciation of the word.

AbstractTheoretical accounts of Greek compounds argue for a close relation between their stress properties and their underlying structure. Compounds that preserve and receive stress at the same position as their second constituent are analyzed as stem-word constructions, while those that receive antepenultimate stress are viewed as belonging to the stem-stem category. Using an auditory lexical decision task, we examine the effect of stress change on the processing of compounds in the light of existing theoretical linguistic accounts. Although our experimental results do not reach statistical significance, we believe that they are informative of the cognitive status and role of stress in compound processing. Finally, they relate to existing theories of compounding in Greek and reflect the complex interaction of the psycholinguistic effects of stress and the structural properties of these constructions.

ABSTRACTWord production difficulties are well documented in dyslexia, whereas the results are mixed for receptive phonological processing. This asymmetry raises the possibility that the core phonological deficit of dyslexia is restricted to output processing stages. The present study investigated whether a group of dyslexics had word level receptive difficulties using an auditory lexical decision task with long words and nonsense words. The dyslexics were slower and less accurate than chronological age controls in an auditory lexical decision task, with disproportionate low performance on nonsense words. The finding suggests that input processing difficulties are associated with the phonological deficit, but that these difficulties may be stronger above the level of phoneme perception.

Early Effects

This study examined whether early effects of semantics could occur in the context of the PRP paradigm. Based on Reynolds and Besner (2004), it was predicted that early effects of semantics would possibly be observed. The study found that the difference in reaction times for the related and unrelated primes for the secondary lexical decision task were constant at the varying SOAs. This additive effect, using the locus-of-slack logic, means that semantic information occurs at or after the central processing bottleneck. Thus, the results did not lend support for our prediction, as semantic information did not feedback to letter representations. The results of this study thus contradict Reynolds and Besner’s (2004) position that the letter level receives information from the semantic and lexical levels. Johnston, McCann, and Remington’s (1995) position, on the other hand, is completely in line with the current data of this study. Their theory that words and semantic occur at or after central processing accounts for the additive effects observed in this study. The current study found that the faster related prime trials in the secondary lexical decision task remained as fast in the short SOA as compared to the long SOA. Thus, the additive effect found lends support that semantic analysis occurs at or after the central attention bottleneck. Although early effects of semantics were not found in the current investigation, one can only imagine that one day researchers may be able to show semantic processing occurring simultaneously with other cognitive tasks.
