Lists of phonologically similar items are more often recalled in the wrong order than phonologically dissimilar items. At recall, patients with schizophrenia were neither especially susceptible to confusing phonologically similar items nor to making disproportionate movement (i.e. order) errors with phonologically similar lists of items. We conclude that patients with schizophrenia employ recall strategies for phonologically similar items in short-term memory that are equivalent to those of healthy controls.

In short-term ordered recall tasks, phonological similarity impedes item and order recall, while semantic similarity benefits item recall with a weak or null effect on order recall. Ishiguro and Saito recently suggested that these contradictory findings were due to an inadequate assessment of semantic similarity. They proposed a novel measure of semantic similarity based on the distance between items in a three-dimensional space composed of the semantic dimensions of valence, arousal, and dominance.

Short-term memory for sequences of verbal items such as written words is reliably impaired by task-irrelevant background sounds, a phenomenon known as the "Irrelevant Sound Effect" (ISE). Different theoretical accounts have been proposed to explain the mechanisms underlying the ISE. Some of these assume specific interference between obligatory sound processing and phonological or serial order representations generated during task performance, whereas other posit that background sounds involuntarily divert attention away from the focal task.

Background: The defective spoken output of persons with aphasia has anomia as a main clinical manifestation. Improving anomia is therefore a main goal of any language treatment.
Aim: This study assessed the effectiveness of a novel, 2-week, rehabilitation protocol (PHOLEXSEM), focused on PHonological, SEmantic, and LExical deficits, aiming at improving lexical retrieval, and, generally, spoken output.

Background: Speech-language pathologists (SLPs) in non-English speaking countries face challenges when assessing children for speech sound disorders (SSD). Exploring their clinical challenges in service delivery-along with their problem-solving approaches-may contribute to the development of instruments for clinical use in such settings.
Aim: The study aimed to explore assessment methods used by Iranian SLPs to identify children with SSD.

The mechanisms underlying forgetting have been central to theorising about verbal short-term and working memory, and the importance of interference as opposed to decay continues to be vigorously debated. Here, we present two experiments to evaluate the nature and locus of phonological interference as a source of forgetting in serial recall. In these experiments, we replicate studies showing that repetition of phonemes across items impairs recall of the later list item, even with visual presentation and typed recall.
