Executive functioning skills and (low) math achievement in primary and secondary school.

Schoolchildren with better executive functioning skills achieve better mathematics results. It is less clear how inhibition, cognitive flexibility, and working memory combine to predict mathematics achievement and difficulty throughout primary and secondary school. This study aimed to find the best combination of executive function measures for predicting mathematical achievement in Grades 2, 6, and 10 and to test whether this combination predicts the probability of having mathematical difficulties across school grades even when fluid intelligence and processing speed were included in the models. A total of 426 students-141 2nd graders (72 girls), 143 6th graders (72 girls), and 142 10th graders (79 girls)-were cross-sectionally assessed with 12 executive tasks, one standardized mathematical task, and a standardized test of intelligence. Bayesian regression analyses found various combinations of executive predictors of mathematical achievement for each school grade spanning Grade 2 to measures of cognitive inhibition (negative priming) and cognitive flexibility (verbal fluency); Grade 6 to measures of inhibition: resistance to distractor interference (receptive attention), cognitive flexibility (local-global), and working memory (counting span); and Grade 10 to measures of inhibition: resistance to distractor interference (receptive attention) and prepotent response inhibition (stop signal) and working memory (reading span). Logistic regression showed that the executive models derived from the Bayesian analyses had a similar ability to classify students with mathematical difficulty and their peers with typical achievement to broader cognitive models that included fluid intelligence and processing speed. Measures of processing speed, cognitive flexibility (local-global), and prepotent response inhibition (stop signal) were the main risk factors in Grades 2, 6, and 10, respectively. Cognitive flexibility (verbal fluency) in Grade 2 and fluid intelligence, which was more stable in all three grades, acted as protective factors against mathematical difficulty. These findings inform practical considerations for establishing preventive and intervention proposals.

Cognitive, emotional, and social factors promoting psychosocial adaptation: a study of latent profiles in people living in socially vulnerable contexts.

Introduction: Social adaptation is a multifaceted process that encompasses cognitive, social, and affective factors. Previous research often focused on isolated variables, overlooking their interactions, especially in challenging environments. Our study addresses this by investigating how cognitive (working memory, verbal intelligence, self-regulation), social (affective empathy, family networks, loneliness), and psychological (locus of control, self-esteem, perceived stress) factors interact to influence social adaptation. Methods: We analyzed data from 254 adults (55% female) aged 18 to 46 in economically vulnerable households in Santiago, Chile. We used Latent profile analysis (LPA) and machine learning to uncover distinct patters of socioadaptive features and identify the most discriminating features. Results: LPA showed two distinct psychosocial adaptation profiles: one characterized by effective psychosocial adaptation and another by poor psychosocial adaptation. The adaptive profile featured individuals with strong emotional, cognitive, and behavioral self-regulation, an internal locus of control, high self-esteem, lower stress levels, reduced affective empathy, robust family support, and decreased loneliness. Conversely, the poorly adapted profile exhibited the opposite traits. Machine learning pinpointed six key differentiating factors in various adaptation pathways within the same vulnerable context: high self-esteem, cognitive and behavioral self-regulation, low stress levels, higher education, and increased social support. Discussion: This research carries significant policy implications, highlighting the need to reinforce protective factors and psychological resources, such as self-esteem, self-regulation, and education, to foster effective adaptation in adversity. Additionally, we identified critical risk factors impacting social adaptation in vulnerable populations, advancing our understanding of this intricate phenomenon.

The semantics of 'unless' conditionals: evidence from 'unless' and disjunctive inferences.

We report the results of an experiment investigating conditional inferences from conditional assertions such as 'Juan won't go to León unless Nuria goes to Madrid' and 'Either Nuria goes to Madrid or Juan won't go to León'. This experiment addresses Dancygier's claims about the semantics of 'unless' by examining inferential endorsements of 'not-A unless B' and 'Either B or not-A' in the canonical order, presenting the categorical premise after the conditional assertions, and in the inverse order, presenting the categorical premise before the conditional assertions. The results of the experiment confirm that the representation of 'unless' includes two possibilities, although as Dancygier holds one of the possibilities may not be complete. The implications of the results are discussed in the context of the strategic nature of conditional reasoning and recent convergent theories of linguistic processing.

Working memory, text comprehension, and propositional reasoning: a new Semantic Anaphora WM test.

The aim of this study was to present a new working memory test following the line of work started by García-Madruga et al. (2007) and to examine its relation to reading comprehension and propositional reasoning measures. In that study we designed a new working memory span test--based on Daneman & Carpenter's (1980) Reading Span Test (RST)--in which the processing task called for an inferential decision--to resolve a pronominal anaphora based on Morpho-Syntactic cues and had people recall the result of this inference. In the current study, besides the RST and the Morpho-Syntactic Anaphora test, we presented a new Semantic Anaphora measure. In order to check the validity of this new Working Memory (WM) task, we used the same reasoning task used in the previous study as well as a new reading comprehension test. The results show the tight relationship amongst working memory, reading comprehension and reasoning, and confirm the validity of the new WM measure.

Inhibitory control and temporal perception in cerebral palsy.

Prepotent response inhibition and temporal perception abilities were explored in a sample of individuals with cerebral palsy relative to typically developing peers. The extent to which inhibitory control difficulties might affect temporal processing was also investigated. For this purpose, two inhibitory control tasks and two duration estimation tasks were given to the groups of cerebral palsy and typically developing children. Results showed inhibition and temporal perception problems in the group with cerebral palsy. A relationship was found between inhibition and temporal estimation performances, which indicates that inhibitory control contributes, at least partially, to acquisition of the temporal processing ability.

A developmental study of the bat/ball problem of CRT: How to override the bias and its relation to executive functioning.

In two experiments, we explored the nature of the bias observed in the bat/ball problem of the cognitive reflection test (Frederick, 2005, J. Econ. Perspect., 19, 25), how to override it, and its relation to executive functioning. Based on the original bat/ball problem, we designed two additional isomorphic items. In Experiment 1, for four age groups, including 7-, 11-, and 15-year-olds and adults, we determined that the bias is related to the System 1 intervention; the performance in this item was not a matter of mathematical ability and it could be facilitated by changing the order in which the problems were presented. In Experiment 2, we determined that for 15-year-olds, good and bad performances in the item were related to executive functioning, particularly response-distractor inhibition, updating information in working memory, and the regulation of attention; however, subtle differences were identified when the problem was performed in a facilitative context compared with a non-facilitative context. The results indicated that cognitive abilities are a necessary but non-sufficient condition to resolve the problem.

The Contributions of Updating in Working Memory Sub-Processes for Sight-Reading Music Beyond Age and Practice Effects.

Music sight reading (SR), has been described as a complex task which involves the simultaneous reading of new non-rehearsed material and performance. Although practice related skill have revealed as the most significant predictor of SR, working memory (WM) processes have shown its relevance in the study of individual differences in SR. We aimed to determine how the updating in WM sub-processes of retrieval/transformation and substitution, could differentially contribute to SR when the effects of age and practice were controlled, and according to the difficulty of the SR tasks and the different indexes of performance measured (SR error, tempo maintenance, rhythmic accuracy, pitch accuracy, articulation accuracy and expressiveness). 131 music students of different ages and levels of instrument knowledge participated in the study. The results showed that whereas the efficiency in the retrieval/transformation sub-processes contributed to SR regardless of the difficulty of the SR tasks, the substitution sub-process also contributed to performance at sight but only in low demanding SR tasks. The results also showed all the updating sub-processes were engaged in SR regarding the proportion of error and rhythmic accuracy. However, both expressiveness and tempo maintenance seemed to be uniquely driven by efficiency in the retrieval/transformation sub-processes, whereas articulation accuracy relied on the efficiency to suppress irrelevant information from WM.

Unless reasoning.

We report the results of two experiments investigating conditional inferences from conditional unless assertions, such as Juan is not in León unless Nuria is in Madrid. Experiments 1 and 2 check Fillenbaum's hypothesis about the semantic similarity of unless with if not and only if assertions; both also examine inferential endorsements (Experiment 1) and endorsements and latencies (Experiment 2) of the four logically equivalent conditional formulations: if A then B, if not-B then not-A, A only if B and notA unless B. The results of these experiments show the similarity of unless and only if confirming that the representation of both conditionals from the outset probably include two possibilities directionally oriented from B to A; results also confirm the especial difficulty of unless assertions. The implications of the results are discussed in the context of recent psychological and linguistic theories of the meaning of unless.

Development of the updating executive function: From 7-year-olds to young adults.

Updating information in working memory (WM) is a critical executive function responsible both for continuously replacing outdated information with new relevant data and to suppress or inhibit content that is no longer relevant according to task demands. The goal of the present research is twofold: First, we aimed to study updating development in 548 participants of 4 different age ranges--7-, 11-, and 15-year-olds and young adults--using the updating task devised by R. De Beni and P. Palladino (2004), which allows differentiating maintenance and inhibition processes. Second, we attempted to determine the relation between these processes across development as well as the differentiation among different types of inhibition processes tapped by this task. Results showed that there was an improvement of memory performance with age along with an upgrading of inhibitory efficiency. However, whereas in memory performance, a progressive increase was observed until the age of 15 years followed by stabilization, in inhibition, a continuous progressive increase was observed until young adulthood. Importantly, results showed that development of the different inhibitory mechanisms does not progress equally. All the groups committed more errors related to inefficient suppression mechanisms in WM than errors related to control of long-term memory interference. Principal component analysis showed that updating implies different subprocesses: active maintenance/suppression of information in WM and control of proactive interference. Developmental trajectories showed that the maintenance/suppression of information in the WM component continues to develop far beyond adolescence but that proactive interference control is responsible for variations in updating across development.

The Development of Metaphor Comprehension and Its Relationship with Relational Verbal Reasoning and Executive Function.

Our main objective was to analyse the different contributions of relational verbal reasoning (analogical and class inclusion) and executive functioning to metaphor comprehension across development. We postulated that both relational reasoning and executive functioning should predict individual and developmental differences. However, executive functioning would become increasingly involved when metaphor comprehension is highly demanding, either because of the metaphors' high difficulty (relatively novel metaphors in the absence of a context) or because of the individual's special processing difficulties, such as low levels of reading experience or low semantic knowledge. Three groups of participants, 11-year-olds, 15-year-olds and young adults, were assessed in different relational verbal reasoning tasks-analogical and class-inclusion-and in executive functioning tasks-updating information in working memory, inhibition, and shifting. The results revealed clear progress in metaphor comprehension between ages 11 and 15 and between ages 15 and 21. However, the importance of executive function in metaphor comprehension was evident by age 15 and was restricted to updating information in working memory and cognitive inhibition. Participants seemed to use two different strategies to interpret metaphors: relational verbal reasoning and executive functioning. This was clearly shown when comparing the performance of the "more efficient" participants in metaphor interpretation with that of the "less efficient" ones. Whereas in the first case none of the executive variables or those associated with relational verbal reasoning were significantly related to metaphor comprehension, in the latter case, both groups of variables had a clear predictor effect.

Mental models in deductive reasoning.

We report research investigating the role of mental models in deduction. The first study deals with conjunctive inferences (from one conjunction and two conditional premises) and disjunctive inferences (from one disjunction and the same two conditionals). The second study examines reasoning from multiple conditionals such as: If e then b; If a then b; If b then c; What follows between a and c? The third study addresses reasoning from different sorts of conditional assertions, including conditionals based on if then, only if, and unless. The paper also presents research on figural effects in syllogistic reasoning, on the effects of structure and believability in reasoning from double conditionals, and on reasoning from factual, counterfactual, and semifactual conditionals. The findings of these studies support the model theory, pose some difficulties for rule theories, and show the influence on reasoning of the linguistic structure and the semantic content of problems.

El propósito de este trabajo es presentar una nueva prueba de memoria operativa y examinar su relación con la comprensión lectora y el razonamiento, en la línea comenzada por el estudio de García-Madruga et al. (2007). En ese estudio se diseñó una nueva medida de amplitud de memoria operativa -basada en Reading Span Test (RST) de Daneman & Carpenter (1980)- en la que la tarea de procesamiento exigía la realización de una inferencia -resolver una anáfora pronominal a partir de los rasgos Morfosintácticos- y los participantes debían recordar el resultado de esta inferencia. Además del RST y la prueba de Anáforas Morfosintácticas, en el presente estudio presentamos una nueva medida de Anáforas Semánticas. Para comprobar la validez de esta nueva tarea de Memoria Operativa (MO) hemos utilizado la misma tarea de razonamiento que en el estudio anterior, así como una nueva tarea de comprensión lectora. Los resultados muestran la estrecha relación entre memoria operativa, comprensión lectora y razonamiento, y confirman la validez de la nueva medida de MO (AU)

The semantics of ‘unless’ conditionals: evidence from ‘unless’ and disjunctive inferences

Se presentan los resultados de un experimento en el que se investigaron las inferencias realizadas a partir de enunciados condicionales como ‘Juan no irá a León a menos que Nuria vaya Madrid’ y ‘O Nuria va a Madrid o Juan no irá a León’. En este experimento se abordan las concepciones de Dancygier sobre la semántica de ‘a menos que’ mediante el estudio de las inferencias que se extraen de ‘no-A a menos que B’ y de ‘o B o no-A’, en el orden canónico, al presentar la premisa categórica después de la afirmación condicional; y en el orden inverso, presentando la premisa categórica antes que la afirmación condicional. Los resultados confirman que la representación de ‘a menos que’ incluye dos posibilidades aunque, como Dancygier sostiene, una de las posibilidades puede no ser completa. Las implicaciones de los resultados se discuten en el contexto de la naturaleza estratégica del razonamiento condicional y de las teorías convergentes recientes sobre el procesamiento lingüístico (AU)

Se presentan los resultados de dos experimentos que investigan las inferencias a partir de enunciados condicionales a menos que, tales como «Juan no está en León a menos que Nuria esté en Madrid». Los experimentos 1 y 2 comprueban la hipótesis de Fillenbaum sobre la similaridad semántica de los enunciados a menos que con si no y sólo si; ambos experimentos examinan las respuestas inferenciales (Experimento 1) y las respuestas inferenciales y las latencias (Experimento 2) de las cuatro formulaciones condicionales lógicamente equivalentes: si A entonces B, si no-B entonces no-A, A sólo si B y no-A amenos que B. Los resultados muestran la similaridad de a menos que y sólo si, confirmando que la representación de ambos condicionales probablemente incluya desde el principio dos posibilidades orientadas direccionalmente desde B a A; los resultados también confirman la dificultad especial de las afirmaciones del tipo a menos que. Las implicaciones de los resultados se comentan en el contexto de las teorías psicológicas y lingüísticas sobre el significado de a menos que (AU)
