[more ▼] Number transcoding is the cognitive task of converting between different numerical codes (i.e. visual “42”, verbal “forty-two”). Visual symbolic to verbal transcoding and vice versa strongly relies on language proficiency. We evaluated transcoding of German-French bilinguals from Luxembourg in 5th, 8th, 11th graders and adults. In the Luxembourgish educational system, children acquire mathematics in German (LM1) until the 7th grade, and then the language of learning mathematic switches to French (LM2). French `70s `80s `90s are less transparent than `30s `40s `50s numbers, since they have a base-20 structure, which is not the case in German. Transcoding was evaluated with a reading aloud and a verbal-visual number matching task. Results of both tasks show a cognitive cost for transcoding numbers having a base-20 structure (i.e. `70s, `80s and `90s), such that response times were slower in all age groups. Furthermore, considering only base-10 numbers (i.e. `30s `40s `50s), it appeared that transcoding in LM2 (French) also entailed a cost. While participants across age groups tended to read numbers slower in LM2, this effect was limited to the youngest age group in the matching task. In addition, participants made more errors when reading LM2 numbers. In conclusion, we observed an age-independent language effect with numbers having a base-20 structure in French, reflecting their reduced transparency with respect to the decimal system. Moreover, we find an effect of language of math acquisition such that transcoding is less well mastered in LM2. This effect tended to persist until adulthood in the reading aloud task, while in the matching task performance both languages become similar in older adolescents and young adults. This study supports the link between numbers and language, especially highlighting the impact of language on reading numbers aloud from childhood to adulthood.

[more ▼] According to the Argumentative Theory, human reasoning has an argumentative function, which consists of devising and evaluating arguments for and against various claims. It is however unclear how humans handle conflicting claims they face in everyday life (i.e., “Bob is telling me that Alice is at the library” vs. “Charles is telling me that Alice is at home”). We here investigate human argumentative reasoning in the light of Formal Argumentation, a research field that develops formal methods to give a normative account of argumentation and reasoning about conflicting information. In Formal Argumentation, multiple argumentation semantics that allow selecting sets of jointly acceptable arguments have been proposed. Nonetheless, it is unclear which of these semantics predicts best how humans evaluate the acceptability of conflicting arguments. We conducted an empirical study in which 130 young adults judged natural language arguments. We instructed them to draw the attack relation between the given arguments and to evaluate the acceptability of each of these arguments. Our results show that human judgments on the existence and directionality of attacks between the arguments conform to theoretical predictions from Formal Argumentation. We further found out that some less well-known argumentation semantics predicted human evaluation better than the most well-known semantics. These findings support the cognitive plausibility of variants of Formal Argumentation and bring new insights into reasoning about conflicting information.

Er wird demnächst Lesen und Schreiben lernen. Antônios Eltern sind Portugiesen, und zu Hause sprechen sie nur ihre Muttersprache. In Cycle 1 (Vorschule) hat Antônio Luxemburgisch sprechen gelernt. Seit er in der Vorschule mit der Sprache in Berührung gekommen ist, hat er sich einen großen Wortschatz in Luxemburgisch angeeignet. Wortschatzkenntnisse gehören zu den wichtigsten Voraussetzungen für das Lesen (Lervåg & Aukrust, 2010). Kinder, die das Lesenlernen mit umfangreicheren Wortschatzkenntnissen beginnen, haben bessere Chancen auf Lernerfolge beim Lesen. Für Kinder in Luxemburg ist es eine große Herausforderung, dass der Schriftspracherwerb in Deutsch erfolgt, das für die meisten von ihnen eine Fremdsprache ist, und nicht in Luxemburgisch, also der Sprache, die sie zuvor in Cycle 1 gelernt haben.

[more ▼] How humans integrate and abstract numerical information across different formats is one of the most debated questions in human cognition. We addressed the neuronal signatures of the numerical integration using an EEG technique tagged at the frequency of visual stimulation. In an oddball design, participants were stimulated with standard sequences of numbers (<5) depicted in single (digits, dots, number words) or mixed notation (dots – digits, number words – dots, digits – number words), presented at 10Hz. Periodically, a deviant stimulus (>5) was inserted at 1.25 Hz. We observed significant oddball amplitudes for all single notations, showing for the first time using this EEG technique, that the magnitude information is spontaneously and unintentionally abstracted, irrespectively of the numerical format. Significant amplitudes were also observed for digits – number words and number words – dots, but not for digits – dots, suggesting an automatic integration across some numerical formats. These results imply that direct and indirect neuro-cognitive links exist across the different numerical formats.

[more ▼] Objectives The present study aimed at combining previous separate research findings having shown that executive functions (EF) contribute to a large range of emotional and behavioral problems among youths with and without neurodevelopmental disorders such as dyslexia and ADHD. Within a unifying framework, it investigated the mediational roles of ADHD symptoms and emotion regulation (ER) difficulties in the association between various EF and internalizing symptoms. Methods The sample included 82 adolescents with ADHD, dyslexia, comorbid ADHD/dyslexia, and typically developing adolescents, thus showing varying EF deficits. Whereas EF (attentional control, inhibition, shifting, working memory) were assessed in behavioral tasks, parents reported on ADHD symptoms, and ER and internalizing (anxiety, depression) symptoms were assessed via self-reports. Results In two-path mediation analyses, ADHD symptoms and ER problems mediated the association between working memory and anxiety (via inattention and ER, a1d21b2 = − .27, 95% CI [− .58, − .04]; via hyperactivity and ER, a1d21b2 = − .19, 95% CI [− .42, − .02]) and depression symptoms (via inattention and ER, a1d21b2 = − .20, 95% CI [− .54, − .03]; via hyperactivity and ER, a1d21b2 = − .24, 95% CI [− .48, − .03]). Hyperactivity and ER, but not inattention and ER, mediated the association between inhibition and internalizing symptoms (predicting anxiety, a1d21b2 = .003, 95% CI [.0001, .009]; predicting depression, a1d21b2 = .004, 95% CI [.002, .009]) as well as between attentional control and internalizing symptoms (predicting anxiety, a1d21b2 = .01, 95% CI [.001, .03]; predicting depression, a1d21b2 = .01, 95% CI [.004, .03]). Conclusions These results offer an insight into how ADHD symptoms and ER problems mediate the association between EF components and internalizing symptoms, with potential implications for prevention and intervention measures.

[more ▼] Over the course of development, children must learn to map a non-symbolic representation of magnitude to a more precise symbolic system. There is solid evidence that finger and dot representations can facilitate or even predict the acquisition of this mapping skill. While several behavioral studies demonstrated that canonical representations of fingers and dots automatically activate number semantics, no study so far has investigated their cerebral basis. To examine these questions, 10-year-old children were presented a behavioral naming task and a Fast Periodic Visual Stimulation EEG paradigm. In the behavioral task, children had to name as fast and as accurately as possible the numbers of dots and fingers presented in canonical and non-canonical configurations. In the EEG experiment, one category of stimuli (e.g., canonical representation of fingers or dots) was periodically inserted (1/5) in streams of another category (e.g., non-canonical representation of fingers or dots) presented at a fast rate (4 Hz). Results demonstrated an automatic access to number semantics and bilateral categorical responses at 4 Hz/5 for canonical representations of fingers and dots. Some differences between finger and dot configuration’s processing were nevertheless observed and are discussed in light of an effortful-automatic continuum hypothesis.

[more ▼] Um Kinder mit einer Lernstörung durch möglichst angepasste Hilfsmaßnahmen unterstützen zu können, ist eine umfassende Diagnostik maßgeblich. Die Diagnostik von Lernstörungen stellt vor allem in multilingualen Kontexten - wie in Luxemburg - eine Herausforderung dar. Auch werden derzeit vorwiegend im Ausland entwickelte diagnostische Tests durchgeführt, welche die luxemburgischen Besonderheiten, wie etwa das Erlernen der schriftsprachlichen und mathematischen Kompetenzen in einer Zweit- oder Drittsprache, nicht berücksichtigen. Ausgehend vom aktuellen Forschungs- und Wissensstand wird ein vertieftes Verständnis im Hinblick auf Lese- und Rechtschreibstörungen und Rechenstörungen dargelegt. Darauf aufbauend werden diagnostische Vorgehensweisen sowie pädagogische Hilfsmaßnahmen mithilfe von Erfahrungswerten praktizierender Fachkräfte aus dem luxemburgischen Förderbereich vorgestellt.

[more ▼] Establishing consistent relationships between neural activity and behavior is a challenge in human cognitive neuroscience research. We addressed this issue using variable time constraints in an oddball frequency-sweep design for visual discrimination of complex images (face exemplars). Sixteen participants viewed sequences of ascending presentation durations, from 25 to 333 ms (40–3 Hz stimulation rate) while their electroencephalogram (EEG) was recorded. Throughout each sequence, the same unfamiliar face picture was repeated with variable size and luminance changes while different unfamiliar facial identities appeared every 1 s (1 Hz). A neural face individuation response, tagged at 1 Hz and its unique harmonics, emerged over the occipito-temporal cortex at 50 ms stimulus duration (25–100 ms across individuals), with an optimal response reached at 170 ms stimulus duration. In a subsequent experiment, identity changes appeared non-periodically within fixed-frequency sequences while the same participants performed an explicit face individuation task. The behavioral face individuation response also emerged at 50 ms presentation time, and behavioral accuracy correlated with individual participants’ neural response amplitude in a weighted middle stimulus duration range (50–125 ms). Moreover, the latency of the neural response peaking between 180 and 200 ms correlated strongly with individuals’ behavioral accuracy in this middle duration range, as measured independently. These observations point to the minimal (50 ms) and optimal (170 ms) stimulus durations for human face individuation and provide novel evidence that inter-individual differences in the magnitude and latency of early, high-level neural responses are predictive of behavioral differences in performance at this function.
