The selection of grammatical features in word production: the case of plural nouns in German 总被引:2,自引:0,他引:2
Two experiments investigate the effect of number congruency using picture-word interference. Native German participants were required to name pictures of single objects (Nase 'nose') or two instances of the same object (Nasen 'noses') while ignoring simultaneously presented distractor words. Distractor words either had the same number or were different in number. In addition, the type of plural formation (same or different inflectional plural suffix) and the semantic relationship (same or different semantic category) between target and distractor were varied in Experiments 1 and 2. Results showed no effect of number congruency in either experiment. Furthermore, the type of inflectional suffix did not exert an influence on naming latencies in Experiment 1, but semantic relationship led to a significant interference effect in Experiment 2. The results indicate that selection of the number feature diacritic in noun production is not a competitive process. The implications of the results for models of lexical access are discussed. 相似文献

Forward and backward visual masking for patterns was investigated as a function of relative overlap between test and masking stimuli, relative intensity of masking stimulus and length of interval between stimuli. The extent of masking increased with increasing spatial overlap between stimuli and with increasing intensity of the masking stimulus. Increasing the interval between the stimuli decreased masking; this occurred at faster rates in backward than in forward masking. Possible mechanisms explaining these findings are discussed. 相似文献

This study investigated the orthographic and phonological contribution of visually masked primes to reading aloud in Dutch.
Although there is a relatively clear mapping between the spelling and sound of words in Dutch, words starting with the letter
c are ambiguous as to whether they begin with the phoneme /S/ (e.g., citroen, “lemon”) or with the phoneme /k/ (e.g., complot,
“conspiracy”). Therefore, using words of this type, one can tease apart the contributions of orthographic and phonological
activation in reading aloud. Dutch participants read aloud bisyllabic c-initial target words, which were preceded by visually
masked, bisyllabic prime words that either shared the initial phoneme with the target (phonologically related) or the first
grapheme (orthographically related) or both (phonologically and orthographically related). Unrelated primes did not share
the first segment with the target. Response latencies in the phonologically related conditions were shorter than those in
the unrelated condition. However, primes that were orthographically related did not speed up responses. One may conclude that
the nature of the onset effect in reading aloud is phonological and not orthographic. 相似文献

Single word production in english: the role of subsyllabic units during phonological encoding 总被引:9,自引:0,他引:9
Five experiments investigated the role of sublexical units in English single word production. L. Ferrand, J. Segui, and G. W. Humphreys (1997) reported a priming effect that was most effective when primes and targets shared the first syllable. Experiments 1A and 1B failed to replicate this effect but Experiment 1B showed that subsyllabic units play a role in speech production. This role was further explored using a picture naming task in Experiment 2. Naming latencies were shortest when the segmental overlap between prime and target (the picture name) was largest, regardless of the syllable structure of the target. Experiments 3 and 4 replicated this segmental overlap effect with different sets of words as targets. Experiment 5 showed that the magnitude of the overlap effect increased with longer prime exposure duration. The implications of these results for theories of phonological encoding in speech production are discussed. 相似文献

The US Supreme Court's June 1992 decision to uphold most of Pennsylvania's law restricting access to abortion confirms that while abortion is still permitted in the US, it is being increasingly regulated. Individual institutions may, however, find ways to permit access to abortion. One hospital formed a mandatory, prospective perinatal ethics committee (PEC) in May 1987 to develop clinical guidelines with which to consider and decide requests by physicians for their patients seeking abortions. The authors obtained the consent of this PEC to study its membership, processes, case outcomes, and clinical decision making. Understanding PEC processes and outcomes may help other institutions to decide whether to institute similar mechanisms. Specifically, the investigators determined the backgrounds and abortion-related beliefs of PEC members and obstetric and gynecology department members, whether the PEC affects the number of abortions performed, how PEC members decide in individual cases, and whether requesting physicians find the PEC helpful. All eleven PEC members and 58 of the 65 medical staff ob/gyn physicians returned background surveys. Study results are presented. Overall, the PEC appeared to function as an affirming regulatory body for second-trimester, medically-indicated terminations and for certain personal choice terminations. Institutional interests were well-served by the PEC and with the assurance of informed consent, the interests of some patients were also well served. 相似文献

Two experiments were carried out to investigate visual masking and target recovery. In the first experiment it was found that with superimposed disks of various sizes masking increases with increasing target-mask similarity and contour proximity. The results of the second study show that the extent of masking produced by a disk, which is slightly larger than the target, is drastically reduced when the mask in turn is followed by a ring, the inner contour of which is contiguous with the contour of the mask. This “facilitation effect” decreases as the interval between the mask and the third stimulus is increased. Target recovery in this situation appears to be brought about as a result of the reduction or elimination of the contour of the mask, which, as the first study has shown, is critical in bringing about the masking effect. The results are discussed in terms of some of the known physiological properties of the visual system. 相似文献
