Near-death experiences (NDEs) are usually associated with positive affect, however, a small proportion are considered distressing. We aimed to look into the proportion of distressing NDEs in a sample of NDE narratives, categorise distressing narratives according to Greyson and Bush’s classification (inverse, void or hellish), and compare distressing and “classical” NDEs. Participants wrote down their experience, completed the Memory Characteristics Questionnaire (assessing the phenomenology of memories) and the Greyson scale (characterising content of NDEs). The proportion of suicidal attempts, content and intensity of distressing and classical NDEs were compared using frequentist and Bayesian statistics. Distressing NDEs represent 14% of our sample (n = 123). We identified 8 inverse, 8 hellish and 1 void accounts. The proportion of suicide survivors is higher in distressing NDEs as compared to classical ones. Finally, memories of distressing NDEs appear as phenomenologically detailed as classical ones. Distressing NDEs deserve careful consideration to ensure their integration into experiencers’ identity. [less ▲]

A reduced influence of prior knowledge has been considered to characterize perceptual abilities in people with autism. In this article, we examine this claim by assessing nonlinguistic and linguistic auditory perception abilities in adults with autism, and by further distinguishing between autism with or without a history of delayed language development. We did not observe any reduced influence of prior language knowledge on the perception of speech stimuli nor did we observe any increased perceptual abilities for atypical variants of speech stimuli or nonspeech auditory stimuli, and this relative to a control group matched on age, nonverbal intellectual efficiency, and reading abilities. Our results challenge models claiming a reduced influence of prior knowledge on perception across domains in the AS. [less ▲]

Numerous studies have shown that verbal working memory (vWM) performance is strongly influenced by linguistic knowledge, with items more familiar at sublexical, lexical and/or semantic levels leading to higher vWM recall performance. Among the many different psycholinguistic variables whose impact on vWM has been studied, the lexical cohort effect is one of the few effects that has not yet been explored. The lexical cohort effect reflects the fact that words sharing their first phonemes with many other words (e.g. alcove, alligator, alcohol…) are typically responded to more slowly as compared to words sharing their first phonemes with a smaller number of words. In a pilot experiment (Experiment 1), we manipulated the lexical cohort effect in an immediate serial recall task and found no effect. Experiment 2 showed that, in a lexical decision task, participants responded more quickly to items stemming from small cohorts, showing that the material used in Experiment 1 allowed for a valid manipulation of the cohort effect. Experiment 3, using stimuli from Experiment 2 associated with maximal cohort effects during lexical decision, failed again to reveal a cohort effect in an immediate serial recall task. We argue that linguistic knowledge impacts vWM performance via continuous interactive activation within the linguistic system, which is not the case for the lexical cohort variable which may influence language processing only at the initial stages of stimulus activation.

Short-term memory (STM) precision has been defined as the resolution with which items are maintained in STM (Joseph et al., 2015). It has to be distinguished from STM capacity, which refers to the number of items that are recalled in STM (Miller, 1956; Cowan, 2010). So far, this concept has received little interest in the verbal STM domain. In two studies, we assessed the sensitivity to different degrees of phonological similarity between memory and probe items as a potential index of verbal STM precision. In Study 1, we assessed STM precision in 60 monolingual, French-speaking young adults. In Study 2, we aimed at taking advantage from the potential differences in STM precision stemming from differing language representations in 35 speakers of German, French, and English. In both studies, participants were presented auditory lists of 6 words. After a delay, a probe was presented, and participants had to decide whether it had been in the list or not. Negative probes showed different degrees of phonological proximity with the target word in the memory list. In Study 1, the lists were presented only in French, while in Study 2, the participants carried out the task in German, French and English. We also assessed comprehension and production of these three languages. Using Bayesian repeated measures ANOVA, we observed in both studies decisive evidence for an influence of phonological proximity on STM probe recognition performance: the more similar the negative probes to the target word, the higher the rate of false recognition. Study 2 revealed additionally that this effect was maintained across languages and that performance correlated positively with language proficiency, the best scores being reached in L1. Finally, we observed significant inter-individual variability in the sensitivity to phonological proximity. These studies suggest that memory-probe phonological similarity is an important variable for the development of measures of STM precision in the verbal domain and is stable across the languages spoken at different levels of mastery.

Peu de paradigmes évaluent la précision des représentations maintenues en mémoire à court terme (MCT), réduisant l’évaluation de la MCT à des scores dichotomiques basés sur le nombre d’items que l’on est capable de restituer, et nous informant très peu sur la nature et la qualité des représentations maintenues. L’objectif de cette étude était de développer un paradigme évaluant la précision des représentations en MCT selon un gradient phonétique-phonologique. Dans ce paradigme, nous avons présenté des listes de non-mots. A l’issue de chaque liste, un non-mot test était présenté, et les participants devaient déterminer si celui-ci avait été présent dans la liste ou non. Au niveau phonétique, nous avons présenté comme non-mot test un non-mot issu de la liste (non-mot cible) dont nous avions modifié le voice onset time (VOT) au niveau du phonème initial afin de le rendre ambigu. Au niveau phonologique, nous avons opposé, entre non-mots cibles et tests, des contrastes phonologiques proches (/p/-/b/) ou plus éloignés (/p/-/t/). Nous avons observé un effet à la fois des contrastes phonétique et phonologiques sur les performances de reconnaissance. De manière importante, l’effet du contraste phonétique ne se manifestait que pour des non-mots cibles présentés en dernière position sérielle. Ces données suggèrent que les informations en MCT sont maintenues avec des niveaux de précision et d’abstraction linguistique différents selon le moment auquel elles ont été encodées. [less ▲]

La mémoire de travail (MDT) verbale interagit fortement avec le système linguistique. Ceci est notamment montré par l’émergence d’effets psycholinguistiques en MDT : les items associés à des représentations langagières plus riches ou robustes bénéficient d’un meilleur rappel en MDT. Une grande partie de ces effets peuvent conceptuellement être expliqués par des modèles langagiers de MDT considérant que l’activation au sein du système langagier se réalise par activation continue et interactive entre les différents niveaux de traitement linguistiques. Cependant, les modèles langagiers de la MDT ont rarement été implémentés sous forme de modèle connexionniste, empêchant leur mise à l’épreuve empirique. Cet exposé présentera un modèle connexionniste intégrant à la fois une architecture linguistique et une architecture de MDT. L’architecture linguistique part du modèle d’activation interactive entre niveaux phonologique, lexical et sémantique de Dell et al. (1997). L’architecture de MDT utilise un principe de marqueur positionnels (Burgess & Hitch, 2006) à travers lequel chaque item est associé à une position spécifique. Ces associations entre les items et leurs positions sont gardées en mémoire via des mécanismes d’apprentissage associatif de type Hebb. A travers une comparaison directe avec des données empiriques, nous montrons que le modèle prédit correctement deux effets psycholinguistiques d’intérêt : l’effet de similarité sémantique et l’effet d’imageabilité. De plus, il permet d’expliquer pourquoi les items entretenant des liens sémantiques forts mènent à une plus grande probabilité d’erreur de transposition (i.e. erreur ordre). [less ▲]

Introduction: Temporal grouping is a benchmark effect for our understanding of serial order processing in verbal short-term memory (VSTM). However, whether other types of grouping effect also impact serial order processing in VSTM is largely unknown. In this study, we compared temporal and semantic grouping effects in immediate serial recall (ISR) and reconstruction tasks to assess whether semantic knowledge can also interacts with serial order processing. Method: Through 4 experiments, 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 of unrelated words were directly compared with lists that were semantically related by triplets of 3 (e.g. three, leaf, branch, cloud, sky, rain) or were interleaved (e.g. three, cloud, leaf, sky, branch, rain). These semantic conditions were manipulated along with two different temporal grouping effects, with verbal lists being temporally grouped with 2 groups of 3 words, or 3 groups of 2 words. In a 5th experiment, we used a visually presented order reconstruction task to further investigate the effect of interleaved semantically related lists. Results: We observed that both temporal and semantic grouping effects independently increased within-group transpositions and decreased inter-group transpositions in the grouped conditions. Interleaved semantically related lists however, did increased within-category transpositions (e.g. recalling leaf, cloud, tree, sky instead of three, cloud, leaf, sky) only in the order reconstruction task. Conclusion: These results provide evidence that semantic knowledge can also influence the pattern of transposition in serial order processing of VSTM. In addition, we show that this result can be attributed to the influence of top-down, controlled attention. [less ▲]
