On the ideational plane, coherence is derived from the perception of continuity
and interdependence of ideational meanings conveyed in the text and inferred
by the interactant on the basis of mental models activated during discourse
processing (van Dijk and Kintsch 1983, Givón 1995, 2001). The most salient
aspects of ideational coherence are continuity of discourse topic and logical
relations holding between segments of discourse. The organization of discourse
content in relation to a discourse topic – often called ‘topical’ or ‘propositional’
coherence (cf. Giora 1985, 1997, Givón 1995, 2001, Gernsbacher 1997) – is
traceable on the basis of continuity of referents, action frames, time, location and
logical relations holding between entities and actions in the mental representation
of the text. It should be noted that since the interpretation of reference and spatio-
temporal markers is pragmatically determined, it is dependent on the shared
background knowledge of the interactants and their experience in discourse
processing (cf. e.g. van Dijk 1997, Miššíková 2005). Obviously, the perception
of discourse coherence is fostered by cohesion relations as they facilitate the
construction of continuity of occurrences of conceptual content items in discourse
and make explicit logical relations holding between events and phenomena
134
represented in discourse. The relevance of utterance themes to discourse topic
at paragraph, discourse segment, and global level is conveyed by patterns of
thematic progression (linear, continuous theme and derived theme) (Daneš 1974,
1995). A change in the type of thematic progression, together with sematic shift
markers, such as changes of time or place or introduction of new referents, may
indicate topic boundaries. Coherence at transition points in discourse may be
fostered by formal topic-shift markers, such as adverbial linkers. Since discourse
organization may be
genre-specific, coherence may also be derived on the basis
of the function of a rhetorical move in the generic structure even in cases when
the relevance of the paragraph/discourse segment topic to the global discourse
topic is indirect.
The perception of coherence on the interpersonal plane is partially dependent
on the type of interaction in which the participants are involved. Thus in
dialogic spoken interaction, which presupposes shared pragmatic context of
communication, all-participants involvement in discourse production and
collaborative negotiation of meaning and management of discourse, interactional
coherence stems to a large extent from the continuity of communicative acts,
which can be analysed on the basis of adjacency pairs and preference structure.
Written interaction comprises a production stage, during which the author tries to
anticipate the implied readers’ expectations and reactions and interacts with the
audience by constructing a discourse world based on mental representations, and
an interpretation stage, during which the reader processes the discourse taking
into consideration the collaborative efforts of the writer and looking for their
signals in the text. Therefore, in written monologic discourse the importance
of interaction structure may be seen as to a large extent given by generic
conventions (cf. Hoey 2001). In all kinds of discourse, however, the perception
of coherence on the interpersonal plane stems from the consistent representation
of participants’ identities and mutual relationships, and is further enhanced by
coherent construction and interpretation of evaluative meanings, related to the
continuity of the interactants’ attitudes and feelings towards the entities and
phenomena about which they are talking or writing. These aspects of interpersonal
coherence are related to the establishment of contact and continuous appeal to
the interlocutor and/or the audience realized by the use of forms of address,
markers of social dialect and politeness, various lexical resources signalling
group affiliation,
evaluation of social actors, actions and events, and structures
attributing opinions and judgments to the speaker/writer or a third party (cf. van
Leeuwen 1996, Hunston and Thompson 1999, Martin and White 2005).
Coherence on the textual plane is associated primarily with the use of cohesive
devices which guide the listener/reader towards a discourse interpretation
intended by the speaker/writer. In agreement with Halliday (1981), cohesion
is seen here as instrumental to the perception of coherence on the ideational
135
and interpersonal planes of discourse. Operating on both the global and local
coherence levels, cohesive devices facilitate the establishment of lexical
and grammatical links between parts of the text and between the text and its
context. Within the present approach, grammatical and lexical mechanisms for
establishing cohesion relations are regarded as interdependent. The categorization
of grammatical cohesive means generally follows Halliday and Hasan’s (1989)
framework, although, in agreement with Cornish’s (2008) cognitive approach,
reference interpretation is extended to encompass both deictic and anaphoric
reference, since they are regarded as referring directly to mental representations
and not to the occurrence of lexical or grammatical items in the text. The
interpretation of lexical cohesion relations is seen as a collaborative achievement
of the interactants which is dependent on their background knowledge through
the knowledge of routines, activity types and complex schemata motivated
socially, culturally and ideologically (Tanskanen 2006); thus it is associated with
evaluation and interpersonal coherence. By participating in the build-up of local
or global cohesive chains, lexical and grammatical cohesive means help maintain
the availability of referents, action and events in the mental representations of the
interactants, while by establishing their referents as thematic across larger parts
of the text, cohesive chains indicate the boundaries of global and local topical
segments. The cohesive role of discourse markers to indicate discourse topic
shifts and to make explicit logical relations holding in the unfolding discourse
enhances the perception of ideational coherence (cf. Povolná 2010).
The above discussion of aspects of coherence suggests that the perception
of coherence stems from the interplay of meanings derived on all planes of
discourse. When constructing a discourse world the speaker/writer projects
into the discourse his/her culturally, experientially and ideologically-biased
judgements and attitudes and assigns status and value to actors, events and
actions related to them. Thus ideational and interpersonal meanings can be
seen as contributing jointly to the efforts of the speaker/writer to impose his/
her ideological perspective and to persuade the listener/reader to accept the
suggested perception of discourse coherence. The listener/reader, however, may
not understand or accept the point of view of the speaker/writer and construct a
different discourse world which agrees with the culturally-, experientially- and
ideologically-biased point of view of the listener/reader, but diverges from the
discourse interpretation intended by the speaker/writer.
