Computational accounts of reading aloud largely ignore context when stipulating how processing unfolds. One exception to this
state of affairs proposes adjusting the breadth of lexical knowledge in such models in response to differing contexts. Three
experiments and corresponding simulations, using Coltheart, Rastle, Perry, Langdon, and Ziegler’s (2001) dual-route cascaded model, are reported. This work investigates a determinant of when a pseudohomophone such as brane is affected by the frequency of the word from which it is derived (e.g., the base word frequency of brain) by examining performance under conditions where it is read aloud faster than a nonword control such as frane. Reynolds and Besner’s (2005a) lexical breadth account makes the novel prediction that when a pseudohomophone advantage is seen, there will also be a base
word frequency effect, provided exception words are also present. This prediction was confirmed. Five other accounts of this
pattern of results are considered and found wanting. It is concluded that the lexical breadth account provides the most parsimonious
account to date of these and related findings. 相似文献

This article is concerned with how information about time and position in a sequence is represented in short-term memory and
expressed in the dynamics of serial recall. Temporal-distinctiveness theories of memory predict that isolating a list item
in time will improve recall accuracy for that item. Although the majority of research in short-term memory has failed to demonstrate
a temporal isolation effect (TIE), there are occasions on which a TIE is observed. The disparity in results has been explained
by assuming that participants can adaptively weight temporal and nontemporal information at retrieval, with differences between
experiments promoting or discouraging reliance on time as a source of episodic information. A particular focus of the present
study is the finding that the TIE is substantially observed in standard serial recall only when participants are instructed
to group the list into minisequences. The findings of two experiments using instructed grouping replicated this effect but
showed that it is attributable to a longer gap at the group boundary enhancing the positive effect of grouping on recall accuracy.
These results show that the hierarchical representations usually associated with temporal grouping are also elicited by instructed
grouping but that an additional and nonspecific benefit to recall obtains from lengthening the pause between groups. An additional
role for time is identified in the timing of responses: The dynamics of input sequences tend to be mirrored in output sequences
for ungrouped lists, whereas the primacy pattern in grouped lists is for a longer duration to speed access to the following
group when that duration occurs at an instructed group boundary. 相似文献

The present study examined the flexibility with which people can adopt different category schemes in the spatial domain. In
a location memory task, participants viewed and estimated the locations of four kinds of objects that were spatially grouped
by object identity. This identity-based arrangement was either congruent or incongruent with the perceptually based, geometric
categories that have been reported in previous research. Four experiments examined the conditions under which these different
category schemes are used to inform estimates of locations. The results showed that use of identity information depended on
the number of objects to be remembered during a trial: When one or two objects were remembered at a time, only geometric categories
affected estimates, but when four objects were to be remembered, both geometric categories and identity groupings affected
estimates. As memory load increases, participants rely on additional sources to inform their estimates of location. 相似文献

In two experiments, we examined the impact of the degree of match between sequential auditory perceptual organization processes
and the demands of a short-term memory task (memory for order vs. item information). When a spoken sequence of digits was
presented so as to promote its perceptual partitioning into two distinct streams by conveying it in alternating female (F)
and male (M) voices (FMFMFMFM)—thereby disturbing the perception of true temporal order—recall of item order was greatly impaired
(as compared to recall of item identity). Moreover, an order error type consistent with the formation of voice-based streams
was committed more quickly in the alternating-voice condition (Exp. 1). In contrast, when the perceptual organization of the
sequence mapped well onto an optimal two-group serial rehearsal strategy—by presenting the two voices in discrete clusters
(FFFFMMMM)—order, but not item, recall was enhanced (Exp. 2). The results are consistent with the view that the degree of
compatibility between perceptual and deliberate sequencing processes is a key determinant of serial short-term memory performance.
Alternative accounts of talker variability effects in short-term memory, based on the concept of a dedicated phonological
short-term store and a capacity-limited focus of attention, are also reviewed. 相似文献

Three experiments were conducted to examine the effect of phonological similarity in simple and complex memory span tasks.
In Experiment 1, participants performed either a simple or a complex span task, and the memoranda within lists were either phonologically
similar or distinct. Phonologically similar lists consisted of words that rhymed.The simple span task was word span. There
were two complex span tasks; one was the original reading span task, and the other was a variant of reading span in which
all the sentences within a list were contextually related. The classic phonological similarity decrement was observed in word
span. In contrast, phonological similarity facilitation was observed in both versions of reading span. This facilitation effect
was further investigated in Experiment 2 using two new versions of reading span. In Experiment 2, the sentences in reading span were either short or long, and the memoranda were presented separately from, and were unrelated
to, the sentences. Again, words within phonologically similar lists rhymed, and again, facilitation was observed. In Experiment
3, phonological similarity was operationalized in terms of feature overlap, rather than rhyme. The classic phonological similarity
decrement was still observed in word span, but facilitation was not observed in complex span. The results suggest that phonological
similarity, when operationalized using words that rhyme, serves as a list retrieval cue and that complex span tasks are more
dependent on cue-driven memory retrieval mechanisms than are simple span tasks. 相似文献

Studies have shown that survival processing leads to superior memorability. The aim of the present study was to examine whether
this survival recall advantage might result from stereotype activation. To test this hypothesis, we conducted a pilot study
and two experiments in which participants were primed with stereotypes (Experiment 1, professor and elderly person; Experiment
2, survival-stereotype). In Experiment 1, 120 undergraduates were randomly assigned to a survival, professor stereotype, elderly
person stereotype, or moving scenario and rated words for their relevance to the imagined scenario. In Experiment 2, 75 undergraduates
were given a survival, survival-stereotype (based on our pilot study), or moving scenario. Both experiments showed that survival
processing leads to a greater recall advantage over the stereotype groups and control group. These data indicate that the
mere activation of stereotypes cannot explain the survival recall advantage. 相似文献

The effects of problem contents and one's scientific background on the detection of correlations and the assessment of their
strength were studied using a task that required active data search, assessment of the strength of a correlation, and monetary
valuation of the correlation's predictive utility. Participants (N = 72) who were trained either in the natural sciences or in the social sciences and humanities explored data sets differing
in contents and actual strength of correlation. Data search was consistent across all variables: Participants drew relatively
small samples whose relative sizes would favor the detection of a correlation, if one existed. In contrast, the assessment
of the correlation strength and the valuation of its predictive utility were strongly related not only to its objective strength,
but also to the correspondence between problem contents and one's scientific background: When the two matched, correlations
were judged to be stronger and more valuable than when they did not. 相似文献

There is a standard version of the history of modern mainstream psycholinguistics that emphasizes an extraordinary explosion
of research in mid twentieth century under the guidance and leadership of George A. Miller and Noam Chomsky. The narrative
is cast as a dramatic shift away from behavioristic principles and toward mentalistic principles based largely on transformational
linguistics. A closer view of the literature diminishes the historical importance of behaviorism, shows a prevailing “written
language bias” (Linell in The written language bias in linguistics: Its nature, origins and transformations, Routledge, London, 2005, p. 4) in psycholinguistic research, and elevates some theoretical and empirical thinking of the
late nineteenth and the early twentieth centuries on language and language use to a far more important role than has heretofore
been acknowledged. In keeping with the theoretical and methodological perspective of the present article, it is particularly
appropriate that the German philologist Philipp Wegener be “given his due in the annals of linguistic sciences” (Koerner 1991,
p. VI*). In his (1885/1991) Untersuchungen über die Grundfragen des Sprachlebens (Investigations regarding the fundamental questions of the life of language; our translation), he began his philological research with the investigation of actual speaking in everyday settings rather
than with analyses of purely formal structure. Moreover, he emphasized understanding language and localized this function
in the listener. Compatible with Wegener’s own investigations is another aspect of speaking that has been most seriously neglected
throughout the history of research on the psychology of verbal communication. For him, as well as for Esper (In C. Murchison
[Ed.], A handbook of social psychology, Clark University Press, Worchester, MA, 1935), the basic and primary genre of dialogical discourse was not ongoing conversation,
but the occasional use of speech in association with other activities. Both Bühler (Sprachtheorie, Fischer, Stuttgart, 1934/1982) and Wittgenstein (Philosophische Untersuchungen/Philosophical investigations, Basil Blackwell, Oxford, 1958) have also emphasized the importance of the genre of occasional speaking. The article concludes
with a discussion of historical shifts in the relationship between psychology and linguistics. 相似文献
