Broca’S Aphasia

The present study investigated the relationship between verbal short-term memory and motor speech processes in healthy control subjects and five patients suffering from Broca's aphasia. Control subjects showed a phonological similarity effect, a word length effect and an articulatory suppression effect, supporting the hypothesis of a phonological store and an articulatory loop component of short-term memory. A similar effect of phonological similarity was observed in the aphasic patients, while the effects of word length and articulatory suppression were reduced. In control subjects, measures of short-term memory were correlated to measures of motor speech rate only if speech rate was assessed in more complex conditions (such as sentence rather than syllable repetition). There was also evidence of an association of speech impairment and short-term memory deficits in the aphasic patients.

Presentation Time

In two experiments, subjects were given 4 presentations of a list divided temporally into 5 groups of 3 items each (grouped) or received the same word lists at a constant rate of presentation (ungrouped) and matched for over-all presentation time. Grouped presentation enhanced recall only in the later serial positions while decreasing recall in the middle serial positions. Results of Exp. I also showed differences in order of recall. The results of Exp. II demonstrated that order of recall was not related to the differences in recall produced by grouping. Implications for short-term memory and memory consolidation were discussed.

Phonological Coding

The effects of irrelevant sounds on reading comprehension and short-term memory were studied in two experiments. In Experiment 1, adults judged the acceptability of written sentences during irrelevent speech, accompanied and unaccompanied singing, instrumental music, and in silence. Sentences varied in syntactic complexity: Simple sentences contained a right-branching relative clause ( The applause pleased the woman that gave the speech) and syntactically complex sentences included a centre-embedded relative clause ( The hay that the farmer stored fed the hungry animals). Unacceptable sentences either sounded acceptable ( The dog chased the cat that eight up all his food) or did not ( The man praised the child that sight up his spinach). Decision accuracy was impaired by syntactic complexity but not by irrelevant sounds. Phonological coding was indicated by increased errors on unacceptable sentences that sounded correct. These error rates were unaffected by irrelevant sounds. Experiment 2 examined effects of irrelevant sounds on ordered recall of phonologically similar and dissimilar word lists. Phonological similarity impaired recall. Irrelevant speech reduced recall but did not interact with phonological similarity. The results of these experiments question assumptions about the relationship between speech input and phonological coding in reading and the short-term store.

Sampling Procedures

Current theories and models of the structural organization of verbal short-term memory are primarily based on evidence obtained from manipulations of features inherent in the short-term traces of the presented stimuli, such as phonological similarity. In the present study, we investigated whether properties of the stimuli that are not inherent in the short-term traces of spoken words would affect performance in an immediate memory span task. We studied the lexical neighbourhood properties of the stimulus items, which are based on the structure and organization of words in the mental lexicon. The experiments manipulated lexical competition by varying the phonological neighbourhood structure (i.e., neighbourhood density and neighbourhood frequency) of the words on a test list while controlling for word frequency and intra-set phonological similarity (family size). Immediate memory span for spoken words was measured under repeated and nonrepeated sampling procedures. The results demonstrated that lexical competition only emerged when a nonrepeated sampling procedure was used and the participants had to access new words from their lexicons. These findings were not dependent on individual differences in short-term memory capacity. Additional results showed that the lexical competition effects did not interact with proactive interference. Analyses of error patterns indicated that item-type errors, but not positional errors, were influenced by the lexical attributes of the stimulus items. These results complement and extend previous findings that have argued for separate contributions of long-term knowledge and short-term memory rehearsal processes in immediate verbal serial recall tasks.
