The acquisition of phonology in a dynamical model of human information processing: a preliminary account

The problem of the acquisition of first language phonology is dealt with within the general information-processing perspective. In this sense, language acquisition is viewed as a process of biologically founded pattern formation due to information exchanges between an adult and a child. Moreover, the process is cognitive in that the child, as a goal-seeking and error correcting individual, undertakes an intricate task of compressing a huge variety of linguistic stimuli in order to build an effective information code. It is further assumed that the basic mechanism which leads to the establishment of fully articulate linguistic ability is that of simulation. The mechanism works through a compression of a set of initial variables (i.e. initial conditions) into a minimum length algorithm and a subsequent construction of an integrated system of language-specific attractors. It is only then that the language user is capable of participating in an information transaction in a fully developed manner.

Idiom processing in aphasic patients

The aim of the present paper is to provide insight into the issue of idiom comprehension in pa- tients who are in the process of recovery from the syndrome of aphasia. Research in figurative language comprehension has seen a robust development in the recent decades. However, it has not been until quite recently that psycholinguists began to delve into the aspect of metaphorical language comprehension in brain damaged populations. It was observed that even though the ability to produce and understand language is recovered in the majority of patients with head trauma, the impairment of some aspects of comprehension may protract. The understanding of idioms, metaphors, similes and proverbs, due to their specific, non-literal character, has been evi- denced to pose a serious problem to aphasic patients, as they fail to decipher the figurative mean- ing of the utterance, and, instead, tend to process the message literally (Papagno et al. 2004). In the present study, three patients who suffered from aphasic disorder were tested for com- prehension of idioms by means of two multiple choice tasks. The obtained results corroborated the hypothesis that patients who are in the process of recovery from aphasia encounter various pitfalls in the comprehension of idiomatic language. Predominantly, they exhibit an inclination to choose the erroneous, literal paraphrases of the presented idioms over their correct, idiomatic counterparts. The present paper aims at accounting for the reasons underlying such a tendency.
