The cognitive mechanisms involved in the “DEGREE ADVERB + PROPER NAME” construction: Evaluating proposals from Construction Grammar and Formal Semantics

There are broad disagreements between existing models regarding the mental representations and processes involved in the "DEGREE ADVERB + PROPER NAME" construction, including disagreements regarding the semantics of the degree device, the category status of the proper name, the construction’s expressed meaning and its (non-)compositionality, and, crucially, the operation that holds between the degree device and the proper name. Our corpus-based investigation into two competing models from Construction Grammar and Formal Semantics shows that these models collectively make useful contributions to the scientific understanding of this construction, but neither is empirically adequate. Most importantly, we find that the construction participates in several non-predicted expressed meanings; multivariate analyses show that the three amenable to statistical analysis cluster with different semantic usage-features. We argue that the best way to account for the construction’s semantics-pragmatics is via a previously-dismissed cognitive mechanism: an enrichment-/strengthening-type operation whereby a pragmatically-supplied scale is added to the message.

Do Children With Developmental Language Disorder Activate Scene Knowledge to Guide Visual Attention? Effect of Object-Scene Inconsistencies on Gaze Allocation

Our visual environment is highly predictable in terms of where and in which locations objects can be found. Based on visual experience, children extract rules about visual scene configurations, allowing them to generate scene knowledge. Similarly, children extract the linguistic rules from relatively predictable linguistic contexts. It has been proposed that the capacity of extracting rules from both domains might share some underlying cognitive mechanisms. In the present study, we investigated the link between language and scene knowledge development. To do so, we assessed whether preschool children (age range = 5;4–6;6) with Developmental Language Disorder (DLD), who present several difficulties in the linguistic domain, are equally attracted to object-scene inconsistencies in a visual free-viewing task in comparison with age-matched children with Typical Language Development (TLD). All children explored visual scenes containing semantic (e.g., soap on a breakfast table), syntactic (e.g., bread on the chair back), or both inconsistencies (e.g., soap on the chair back). Since scene knowledge interacts with image properties (i.e., saliency) to guide gaze allocation during visual exploration from the early stages of development, we also included the objects’ saliency rank in the analysis. The results showed that children with DLD were less attracted to semantic and syntactic inconsistencies than children with TLD. In addition, saliency modulated syntactic effect only in the group of children with TLD. Our findings indicate that children with DLD do not activate scene knowledge to guide visual attention as efficiently as children with TLD, especially at the syntactic level, suggesting a link between scene knowledge and language development.

Digital embryos: a novel technical approach to investigate perceptual categorization in pigeons (Columba livia) using machine learning

Pigeons are classic model animals to study perceptual category learning. To achieve a deeper understanding of the cognitive mechanisms of categorization, a careful consideration of the employed stimulus material and a thorough analysis of the choice behavior is mandatory. In the present study, we combined the use of “virtual phylogenesis”, an evolutionary algorithm to generate artificial yet naturalistic stimuli termed digital embryos and a machine learning approach on the pigeons’ pecking responses to gain insight into the underlying categorization strategies of the animals. In a forced-choice procedure, pigeons learned to categorize these stimuli and transferred their knowledge successfully to novel exemplars. We used peck tracking to identify where on the stimulus the animals pecked and further investigated whether this behavior was indicative of the pigeon’s choice. Going beyond the classical analysis of the binary choice, we were able to predict the presented stimulus class based on pecking location using a k-nearest neighbor classifier, indicating that pecks are related to features of interest. By analyzing error trials with this approach, we further identified potential strategies of the pigeons to discriminate between stimulus classes. These strategies remained stable during category transfer, but differed between individuals indicating that categorization learning is not limited to a single learning strategy.

A Quantitative Framework for Identifying Patterns of Route-Use in Animal Movement Data

Animal movement along repeatedly used, “habitual” routes could emerge from a variety of cognitive mechanisms, as well as in response to a diverse set of environmental features. Because of the high conservation value of identifying wildlife movement corridors, there has been extensive work focusing on environmental factors that contribute to the emergence of habitual routes between protected habitats. In parallel, significant work has focused on disentangling the cognitive mechanisms underlying animal route use, as such movement patterns are of fundamental interest to the study of decision making and navigation. We reviewed the types of processes that can generate routine patterns of animal movement, suggested a new methodological workflow for classifying one of these patterns—high fidelity path reuse—in animal tracking data, and compared the prevalence of this pattern across four sympatric species of frugivorous mammals in Panama. We found the highest prevalence of route-use in kinkajous, the only nocturnal species in our study, and propose that further development of this method could help to distinguish the processes underlying the presence of specific routes in animal movement data.

Predicting the Mathematical Abstraction Processes Using the Revised Bloom’s Taxonomy: Secondary School 7th Graders

In this study, it was investigated whether it would be possible to observe abstraction processes of secondary school 7th graders using the Revised Bloom’s Taxonomy. For this purpose, eight students participated in the study. The study was conducted at a state secondary school in Turkey. Purposeful sampling method was used in the selection of students and different students were examined by their achievement levels. The research was modeled as a case study and the data were obtained through interviews. Therefore, the data were collected through an interview form developed by the researchers. The collected data were analyzed according to descriptive analysis method. The findings show that the abstraction process differs according to the dimensions of the taxonomy. Accordingly, it was determined that a student who abstracts information should behave at least at the application level in the cognitive level and at least at the conceptual knowledge level in the knowledge dimension. It was also considered that the Revised Bloom’s Taxonomy categorized the cognitive mechanisms required by abstraction processes thoroughly. Supporting this study with quantitative data is suggested so that the findings may become more significant.

Belief Updating and Paranoia in Individuals with Schizophrenia

Background and Hypothesis: Persecutory delusions are among the most common delusions in schizophrenia and represent the extreme end of the paranoia continuum. Paranoia is accompanied by significant worry and distress. Identifying cognitive mechanisms underlying paranoia is critical for advancing treatment. We hypothesized that aberrant belief updating, which is related to paranoia in human and animal models, would also contribute to persecutory beliefs in individuals with schizophrenia. Study Design: Belief updating was assessed in 42 schizophrenia and 44 healthy participants, using a 3-option probabilistic reversal learning (3-PRL) task. Hierarchical Gaussian filter (HGF) was used to estimate computational parameters of belief updating. Paranoia was measured using the Positive and Negative Syndrome Scale (PANSS) and the revised Green et al. Paranoid Thoughts Scale (R-GPTS). Unusual thought content was measured with the Psychosis Symptom Rating Scale (PSYRATS) and the Peters et al. Delusions Inventory (PDI-21). Worry was measured using the Dunn Worry Questionnaire. Results: Consistent with prior work, paranoia was significantly associated with elevated win-switch rate, prior on volatility and sensitivity to volatility in both schizophrenia and across the whole sample. These relationships were specific to paranoia and did not extend to unusual thought content or measures of anxiety. We did, however, find a significant indirect effect of paranoia on the relationship between prior beliefs about volatility and worry. Conclusions: This work provides evidence that relationships between belief updating parameters and paranoia extend to schizophrenia, may be specific to persecutory beliefs, and contribute to theoretical models implicating worry in the maintenance of persecutory delusions.

Unlocking adults’ implicit statistical learning by cognitive depletion

Human learning is supported by multiple neural mechanisms that maturate at different rates and interact in mostly cooperative but also sometimes competitive ways. We tested the hypothesis that mature cognitive mechanisms constrain implicit statistical learning mechanisms that contribute to early language acquisition. Specifically, we tested the prediction that depleting cognitive control mechanisms in adults enhances their implicit, auditory word-segmentation abilities. Young adults were exposed to continuous streams of syllables that repeated into hidden novel words while watching a silent film. Afterward, learning was measured in a forced-choice test that contrasted hidden words with nonwords. The participants also had to indicate whether they explicitly recalled the word or not in order to dissociate explicit versus implicit knowledge. We additionally measured electroencephalography during exposure to measure neural entrainment to the repeating words. Engagement of the cognitive mechanisms was manipulated by using two methods. In experiment 1 (n = 36), inhibitory theta-burst stimulation (TBS) was applied to the left dorsolateral prefrontal cortex or to a control region. In experiment 2 (n = 60), participants performed a dual working-memory task that induced high or low levels of cognitive fatigue. In both experiments, cognitive depletion enhanced word recognition, especially when participants reported low confidence in remembering the words (i.e., when their knowledge was implicit). TBS additionally modulated neural entrainment to the words and syllables. These findings suggest that cognitive depletion improves the acquisition of linguistic knowledge in adults by unlocking implicit statistical learning mechanisms and support the hypothesis that adult language learning is antagonized by higher cognitive mechanisms.

Neuropsychological and psychopathological variables modulating cognitive insight in people with schizophrenia

Cognitive insight is the capacity of patients with schizophrenia to evaluate their psychotic experiences and respond to the corrective feedback. The relationship with their neuropsychological functions and the modulation exercised by mood and anxiety are still not clear. To make advances and deepen our knowledge would have an important impact on our understanding of the cognitive mechanisms and intervention programmes. Two samples were chosen, one clinical with persons suffering from schizophrenia (n = 43) and another with healthy individuals (n = 50). The Cognitive Insight Scale (BCIS), a neuropsychological battery and questionnaire concerning depression and anxiety, was applied to them. The results suggest an influence of anxiety and the deficits in cognitive flexibility on the development of the mechanisms of Self-Reflection in persons with schizophrenia, with a different pattern to that found in healthy individuals. The results are discussed with respect to the intervention programmes. El insight cognitivo es la capacidad de los pacientes con esquizofrenia de evaluar sus experiencias psicóticas y responder a la retroalimentación correctiva. Su relación con el funcionamiento neuropsicológico y la modulación que ejercen el estado de ánimo y la ansiedad están aún poco claras. Avanzar y profundizar en su conocimiento tendría un impacto importante sobre la comprensión de los mecanismos cognitivos y los programas de intervención. Se seleccionaron dos muestras, muestra clínica, con personas con esquizofrenia (n = 43), muestra personas sanas (n = 50), a las que se aplicó la Escala de insight cognitivo (EICB), una batería neuropsicológica y cuestionarios de depresión y ansiedad. Los resultados sugieren una influencia de la ansiedad y de los déficits de flexibilidad cognitiva en el desarrollo de los mecanismos de la Auto-Reflexión en personas con esquizofrenia, con un patrón diferente al encontrado en personas sanas. Se discuten los resultados con respecto a los programas de intervención.

An Eye-Tracking Study on the Word Order Preference and the Effect of Phrasal Length in Korean

Objectives: Although Korean is a typical free word order language, when the same logical meaning is realized in several sentences with different word order, preference for the word order and the processibility of that sentence may vary. In this study, we investigated the word order preference on the instrumental adjunct and argument (direct object) of Korean when they were both short and when one of the two components was lengthened in the sentence using Eye-tracking technology. Additionally, the underlying cognitive mechanisms of the word order preference were discussed.Methods: Thirty-five college students were asked to read 24 sentences consisting of a condition in which both the adjunct and argument were short and one of them was lengthened, and their gaze was tracked.Results: When both components were short, the preferred word order was not confirmed. However, when one of the two components was lengthened, the canonical word order effect of putting the instrumental adjunct before the object argument and the LbS (Long before Short) effect of placing the lengthened components before the short ones were confirmed.Conclusion: The word order preference seems to reflect the strategy of keeping essential components close to the verb and minimizing the efficiency of integrated processing between critical components such as the head of an argument. However, the preference may vary depending on the burden of sentence processing or the level of the cognitive capacity of the processor. The timing at which word order preference is reflected may also vary depending on how strong the effect of the canonical order between two components is.

Comparative phraseological units: features of the subclass (by an example of the German language)

The article analyzes the features of comparative phraseological units, which are distinguished by researchers into a separate subclass existing in different languages. The relevance of the topic is confirmed by the unquenchable interest in comparative phraseological units from the linguistic point of view and a new perspective of their consideration within the framework of the author's phraseology in works of artistic discourse. The article identifies cognitive mechanisms common to different linguocultures that underlie the structure of comparative phraseological units, as well as national and cultural differences manifesting in semantic variation where there is lexical equivalence of comparative phraseological units in different languages. In this regard, the importance of the culture-oriented and the research approach by the translation of comparative phraseological units is emphasized. A comprehensive analysis of comparative phraseological units as a phraseology phenomenon is necessary for an adequate consideration of their place within the author's phraseology on the basis of selected works of the German-speaking Swiss writer Urs Widmer. Artistic discourse is presented as a literary communicative phenomenon, actualizing linguistic parameters. The selected works are saturated with phraseological units demonstrating examples of language game at the phraseological level, while in quantitative terms, comparative phraseological units make up a small percentage 13 % and 10 %, respectively, of the total volume of phraseological units in two texts. It is noted that not all comparative phraseological units used by Widmer are recorded in dictionaries. The author of the article assigns them to this subclass not only due to the presence of formal signs (structure, idiomaticity), but also on the basis of the corpus approach, which reveals enough evidence of the prevalence of comparative phraseological units in the language. Among the methods used, it is also necessary to note content analysis and a comparative approach, which enables to draw parallels between different languages (between German, Russian and English). It is stated that in spite of all the expressiveness of comparative phraseological units, their rigid logical structure limits the game potential and excludes them from the language game, which the author implements in the works selected for analysis.
