Recent theoretical accounts of verbal and visuo-spatial short-term memory (STM) have proposed the existence of domain-general mechanisms for the maintenance of serial order information. These accounts are based on the observation of similar behavioural effects across several modalities, such as temporal grouping effects. Across two experiments, the present study aimed at extending these findings, by exploring a STM modality that has received little interest so far, STM for musical information. Given its inherent rhythmic, temporal and serial organisation, the musical domain is of interest for investigating serial order STM processes such as temporal grouping. In Experiment 1, the data did not allow to determine the presence or the absence of temporal grouping effects. In Experiment 2, we observed that temporal grouping of tone sequences during encoding improves short-term recognition for serially presented probe tones. Furthermore, the serial position curves included micro-primacy and micro-recency effects, which are the hallmark characteristic of temporal grouping. Our results suggest that the encoding of serial order information in musical STM may be supported by temporal positional coding mechanisms similar to those reported in the verbal domain. [less ▲]

The lexicality effect in verbal short-term memory (STM), in which word lists are better recalled than nonword lists, is considered to reflect the influence of linguistic long-term memory (LTM) knowledge on verbal STM performance. The locus of this effect remains however a matter of debate. The redintegrative account considers that degrading phonological traces of memoranda are reconstructed at recall by selecting lexical LTM representations that match the phonological traces. According to a strong version of this account, redintegrative processes should be strongly reduced in recognition paradigms, leading to reduced LTM effects. We tested this prediction by contrasting word and nonword memoranda in a fast encoding probe recognition paradigm. We observed a very strong lexicality effect, with better and faster recognition performance for words as compared to nonwords. These results do not support a strong version of the redintegrative account of LTM effects in STM which considers that these LTM effects would be the exclusive product of reconstruction mechanisms. If redintegration processes intervene in STM recognition tasks, they must be very fast, which at the same time provides support for models considering direct activation of lexico-semantic knowledge during verbal STM tasks.

The contribution of lexical and semantic knowledge to verbal short-term memory (vSTM) span is explained by language-based models, assuming that vSTM is deeply grounded within the linguistic system with to-be-remembered items being activated in a non-strategic and automatic manner. However, direct evidence for a non-strategic account of lexical and semantic contributions to vSTM span is scarce. In this study, we assessed the influence of several types of long-term linguistic knowledge (lexicality, lexical frequency, semantic similarity and imageability) on vSTM using a fast encoding running span procedure preventing any strategic processes during encoding. We observed reliable effects of lexicality (words vs. nonwords, Experiment 1), lexical frequency (high vs. low frequency words, Experiment 2) and semantic similarity (related vs. unrelated lists, Experiment 3) on running span performance. However, word imageability (high vs. low imageability words, Experiment 4) did not consistently impact running span performance. Experiment 5 showed that the imageability effect only appears in standard immediate serial recall conditions which do not prevent list-strategic encoding. This study provides novel evidence for linguistic accounts of vSTM by demonstrating a robust impact of lexical and surface-level semantic knowledge on vSTM in non-strategic, fast-encoding conditions.

We present a new measure of everyday memory, the Questionnaire of Memory (Q-MEM), which is specifically adapted for the ecological assessment of memory disorders in school-age children and constructed with four sections tapping effortful/intentional learning, automatic/procedural learning, prospective memory/organization, and working memory. Confirmatory Factor Analyses supported the Q-MEM’s four-factor structure in 700 five-to twelve-year-old children. The analyses also revealed a good internal reliability and a good test-retest fidelity. Finally, comparisons between Q-MEM profiles of children with learning disabilities and typically developing children revealed significant differences. Therefore, the Q-MEM is a promising measure for identifying memory problems in children. [less ▲]

Recent studies have demonstrated that both ordinal number processing and serial order working memory (WM) abilities predict calculation achievement. This raises the question of shared ordinal processes operating in both numerical and WM domains. We explored this question by assessing the interrelations between numerical ordinal, serial order WM, and arithmetic abilities in 102 7- to 9-year-old children. We replicated previous studies showing that ordinal numerical judgement and serial order WM predict arithmetic abilities. Furthermore, we showed that ordinal numerical judgement abilities predict arithmetic abilities after controlling for serial order WM abilities while the relationship between serial order WM and arithmetic abilities was mediated by numerical ordinal judgement performance. We discuss these results in the light of recent theoretical frameworks considering that numerical ordinal codes support the coding of order information in verbal WM. [less ▲]

The distinction between autism and Asperger syndrome has been abandoned in the DSM-5. However, this clinical categorization largely overlaps with the presence or absence of a speech onset delay which is associated with clinical, cognitive, and neural differences. It is unknown whether these different speech development pathways and associated cognitive differences are involved in the heterogeneity of the restricted interests that characterize autistic adults.

Patients in a minimally conscious state (MCS) have been subcategorized in MCS plus and MCS minus, that is, with or without command following capacity respectively. We aimed to characterize this residual capacity in both patient groups by means of resting state fMRI. We hypothesized a higher connectivity in MCS plus as compared with MCS minus in language-related networks, that is the left fronto-parietal network (FPN). Our sample includes 10 MCS plus and 9 MCS minus who match for age, gender, etiology and disease duration, as well as 35 healthy controls. We performed a seed-based resting state analysis using CONN toolbox2. We investigated the left FPN, and also the right FPN, the auditory network and the default mode network (DMN) in order to exclude the influence of perception of surrounding, auditory capacity, or internal thoughts. We employed a ROI-to-ROI analysis to investigate the inter-hemispheric connectivity and we investigated inter-group differences in grey and white matter volume by means of voxel-based morphometry (VBM). We observed a higher functional connectivity in controls than in patients, as well as in MCS plus as compared to MCS minus patients. Specifically, with DLPFC as seed, the left FPN was more connected in MCS plus patients to the left temporo-occipital fusiform cortex. No significant differences were found between both patient groups in the right FPN, the auditory network and the DMN, or using the ROI-to-ROI analyses and the VBM. Our results suggest that the clinical sub-categorization of MCS is sustained by functional connectivity differences in a language-related executive control network. MCS plus and MCS minus patients are not differentiated by networks involved in auditory processing, perception of surroundings and internal thoughts, nor by inter-hemispheric connectivity and morphology.

Introduction: Verbal short-term memory (VSTM) is a cognitive function allowing the temporary storage of linguistic information. This function strongly rely on stored long-term memory (LTM) knowledge: verbal items associated with richer LTM representations are better recalled in VSTM. These LTM aspects are generally considered as being independent from serial order processing, that is, the ability to maintain the order in which verbal items appears within a sequence. The purpose of this study was to demonstrate that serial order processing in VSTM can also interact with LTM knowledge, focusing more specifically on the interactions with semantic knowledge. Method: Forty participants performed a VSTM task in which they were invited to listen and recall in the correct serial order lists composed of 6 words; verbal lists were either semantically related or they were not. The words were grouped by groups of 3 semantically related words (e.g. three, leaf, branch, cloud, sky, rain) in the related condition. Results: We observed no effect of semantic grouping on the proportion of order errors. However, semantic grouping dramatically influenced the pattern of transposition errors: while statistically less inter-group transpositions (i.e. erroneously recalling one item from one semantic category to another) were observed in the related condition, we also observed statistically more intra-group transpositions (i.e. transposing two items within the same semantic category). Discussion: These results show that semantic knowledge can influence serial order processing in VSTM. They also support recent theoretical proposals stating that serial order processing strongly interact with the activation within the semantic system. [less ▲]
