Recent years have seen an upsurge of interest in the notion of salience in linguistics
and related disciplines. The attention literature distinguishes two broad types of
perceptual salience (Summerfield and Egner, 2009; Awh et al., 2012). First, a stimulus
can be salient—i.e., foremost in one's mind—because it is cognitively preactivated.
This type of salience, sometimes referred to as top-down salience, may occur if a
stimulus is expected because it is part of a cognitive routine, if it has recently
been mentioned, or due to current intentions of the perceiver. Research on salience
as a semantic-pragmatic phenomenon has shown that top-down salience can account for
systematic preferences in the interpretation of figurative utterances, pronominal
antecedents, implicatures, and discursive links (Geeraerts, 2000; Giora, 2003; Chiarcos
et al., 2011; Jaszczolt and Allan, 2011).
While in top-down salience, perceivers endogenously direct their attention to a certain
stimulus, in the second type of salience, bottom-up salience, it is the stimulus itself
which attracts attention. In prototypical cases of bottom-up salience, the stimulus
stands out because it is incongruous with a given ground by virtue of intrinsic physical
characteristics. But a stimulus may also cause surprise by virtue of deviating from
a cognitive ground, e.g., when violating social or probabilistic expectations (Clark,
2013). This has prompted researchers to examine the relationship between expectations
and the perceptual salience of linguistic stimuli in new ways (Hanulíková et al.,
2012; Rácz, 2012; Hanulíková and Carreiras, 2015; Blumenthal-Dramé, 2016a,b; Roller,
2016; Blumenthal-Dramé et al., 2017), and inspired us to organize a workshop devoted
to this particular area.
In October 2014, the Freiburg Institute of Advanced Studies (FRIAS) hosted the workshop
“Perceptual linguistic salience: Modeling causes and consequences”, organized by the
editors of this volume. Bringing together researchers from psycholinguistics, sociolinguistics,
neurolinguistics, and cognitive linguistics, the workshop sought to explore the notion
of perceptual salience and its explanatory potential for the domains of language processing,
variation, and change. Several questions arising from the stimulating discussions
were listed in the call for papers for this Research Topic and included the following:
Which cognitive processes underlie the differential treatment of salient vs. non-salient
linguistic percepts?
How can these processes be accommodated within psycholinguistic models?
How can the perceptual salience of linguistic forms and variants be operationalized?
To what extent is salience an intrinsic feature of linguistic forms (e.g., dialectal
variants), and to what extent does it result from contextual factors or prior experience
with language?
This volume features nine contributions including five original research articles,
one review, and three commentaries that addressed the above questions in very interesting
ways. Several contributions discuss which factors or prior experience with language
underlie the differential treatment of salient linguistic percepts, and how can they
be operationalized and modeled. Jaeger and Weatherholtz argue that sociolinguistic
salience can be quantified using computational psycholinguistics. A distinction is
made between the initial salience of a novel variant and the cumulative product of
experienced exposures to a variant. A variant's salience may be predicted based on
its surprisal and frequency. In support of this view, Schmid and Günther propose a
unified framework of salience which aims at reconciling seemingly contradictory uses
of this notion in the literature: cues are either categorized as salient because they
confirm expectations, or because they violate them. Zarcone et al. suggest that an
articulated model of salience should take into account attention, affect, and predictability
at different levels of processing, and that these dimensions and their interactions
can be straightforwardly accommodated within the Predictive Coding framework. Finally,
Giraudo and Del Maso present a critical review of so-called decompositional accounts
of morphological processing. They argue that the salience of morphemes cannot be reduced
to formal factors, and that semantic factors and relationships between holistically
represented complex words should also be integrated into models of morphological processing.
Several contributions address the hypothesis that salient items might function as
cognitive reference points that structure and give access to certain cognitive domains
(e.g., sociolinguistic stereotypes), thereby influencing the perception and categorization
of less salient items of the same domain (Rosch, 1975; Langacker, 1993; Hanulíková
and Weber, 2012). On the basis of recent theories of enregisterment and exemplar processing,
Jensen investigates percepts resulting from sociolinguistic or socio-cognitive salience,
more exactly the salience of various morphosyntactic forms in vernacular Tyneside
(Northeast England). This study brings to the fore the role of place as strongly shaping
both a community's and an individual's linguistic identity and self-representation.
Llamas et al. present metrics for determining the relative salience of phonetic variables
in the Scottish-English border zone. This paper substantiates the fact that the choice
of features which ultimately become sociolinguistically salient is largely arbitrary.
What matters is sufficient agreement among the members of the relevant speech community
as to which structural features are considered to function as signals of group membership.
Using eye-tracking, Grohe and Weber show for regional dialects of German that salience
clearly has an effect on native accent adaptation, but only if objective criteria
for salience apply.
The notion of perceptual salience is inextricably linked to issues concerning language
acquisition. Cintrón-Valentín and Ellis examine effects of physical salience and attentional
biases in the visual and auditory modalities in second language acquisition. Chinese
and English native speakers were trained on Latin tense morphology under different
types of explicit form-focused instructions, some of which successfully increased
learners' attention to less salient morphological features. Rácz et al. use artificial
language learning and show that the social-cognitive salience of non-linguistic contexts
influences learning of morphological features. Learning is easier with a coherent
and interpretable social context (such as gender of the speaker) as opposed to accidental
links between the speaker and the construction (such as front-facing vs. side-facing).
Taken together, the papers featured in this volume contribute to our understanding
of how the perceptual salience of linguistic forms and variants can be theoretically
framed and methodologically operationalized in different areas of linguistic processing.
