Combined ACLC SMART lecture, dr. Laura Bos, and a SMART guest speaker
Bos: Neurolinguistic studies on time reference
There are two guest speakers at this combined ACLC SMART lecture. Laura Bos is the ACLC guest speaker, the title of her lecture and her abstract are now available. The SMART guest speaker will be anounced shortly.
SMART is an acronym for Speech & Language, Music, Art, Reasoning & Thought. SMART CS has a monthly newsletter, with upcoming events, news, and an interview with someone at the UvA working in the field of cognition.

Recently, Bastiaanse and colleagues (2011) identified past time reference morphology as a particular source of the prominent tense inflection problems in agrammatic aphasia. Using a verb with past time reference requires additional processing, because the past verb form has to be linked to an event in discourse — this in contrast with non-past time reference. They captured this in the Past Discourse Linking Hypothesis (PADILIH).
In my talk, I will report on neurolinguistics studies in different populations (healthy, agrammatic aphasic and fluent aphasic) and in different languages in support of this theory. The hypothesis has its origin in agrammatic aphasia, however, we explored whether the PADILIH can be extended to fluent aphasic and healthy speakers. Furthermore, as tense is not equivalent to time-reference, the hypothesis should apply to discourse-linked verb forms, regardless of tense. We therefore tested constructions in which reference to the past is made by simple past (i.e. ‘V-ed’), and by an auxiliary in present tense plus a participle, the periphrastic past (i.e. ‘has+V-ed’). The studies were completed within the Erasmus Mundus PhD Program International Doctorate in Experimental Approaches to Language and Brain as part of my dissertation (Bos, 2014).
