Categorical learning plays a foundational role in language development. By reviewing comparative studies on categorical learning in humans and nonhuman animals, we show that categorical learning displays evolutionary continuity across invertebrates and vertebrates. Great apes and parrots can be trained to produce categories of (proto-)language-like symbols in different modalities. From the neurological perspective, we show that as a conserved brain structure, the basal ganglia are involved in categorical learning across species, and language processing in humans. This raises the possibility that categorical learning is one of the crucial cognitive foundations for language evolution.

The 45th Annual Meeting of the Cognitive Science Society presents the latest research across cognitive science and highlights the theme of Cognition in Context.

Alcohol binge drinking is ubiquitous among young adults. While the neurotoxic effects of general alcohol consumption are well known, binge drinking has unique effects on the brain through the intoxication and withdrawal cycle. In particular, the research regarding binge drinking and attention is mixed; this study investigates this relationship in young adults. University students (N=105) were recruited. Socio-demographic and alcohol use information was collected, then participants completed cognitive tasks based on the Attention Network Theory: alerting, orienting, and executive control. Binge drinking, sex, and age of first binge did not predict attention impairment, nor did sex moderate the relationship. The tasks measuring attention did not relate in the expected manner. While there were no differences in attention performance between those who binge drink and controls in this study, the relationship between binge drinking and attention impairments in young adults may be more nuanced and future research directions are suggested.

The Effects of Binge Drinking on Attention in Young Adults.

Traditionally considered random noise, variability in behaviour in fact contains meaningful structure. Healthy functioning can be characterised by behavioural variability that is statistically self-similar (i.e., exhibits 1/f scaling), while disease or injury can result in deviations from this pattern. To date this work has focused predominantly on physical conditions. Little is known about the link between mental health and 1/f scaling. To address this gap, in the present study participants (n = 61) completed a simple walking task during which their gait variability was captured. Cognitive load, a factor known to impact 1/f scaling, was manipulated and symptoms of social anxiety assessed. As expected, being distracted by a cognitive task led to deviations in gait structure away from 1/f scaling. Notably, this effect was amplified by symptoms of social anxiety. This provides initial evidence that difference in mental health status impacts the structure of behaviour.

Exploring the impact of social anxiety on behavioural variability

The current study investigates whether a running man's pictogram on emergency signage is as effective as an arrow in conveying direction, especially in emergencies. We conducted two experiments to address the following questions: first, comparing the ease of reading the two signages, and second, presenting an incomplete image of a running man (RM) signage design pictogram to investigate important components of running man that contribute in conveying direction. In both conditions, the participant's task is to identify the orientation/direction and choose the keys corresponding to the right/left orientation/direction.

This paper presents a theoretical description of metacognition in architectural design. The assumption is that metacognition happens when an architect expresses self-awareness and that’s likely to happen when he/she acquires a global view of the design process. Self-awareness does not necessarily mean high confidence rating, so this needs to be measured separately. During design, architects are immersed in a sequential decision-making process with limited links/references backwards and forwards to immediately adjacent design actions. At certain points during design, possibly evoked by a stimuli or a challenge, architects rise to a higher order awareness where they construct a global view of parts or the whole of the design process, and understand, in parts or in full, the structure and causalities underlying their design decisions within the context of the design process and perhaps within a wider context that is situated in the social world. This is where architects are likely to declare or express their level of confidence about the actions they have made thus far and set longer term strategies on how they are going to manage their design decisions.

Metacognition in architectural design

There is debate about when children can think counterfactually about doubly-determined events (McCormack et al., 2018; Nyhout, Henke, & Ganea, 2017). We tested whether counterfactual thinking about past events, requiring mental time travel, was harder than thinking about ongoing events. 68 3- to 6-year-olds saw a box which lit up when activator blocks were placed on it. In doubly-determined current trials, a red and a blue block (both activators) were placed on the box which lit up. Children were asked “If we had not put the red block on the machine, would the light still be on now?” (Correct “yes”). In doubly-determined past trials, blocks were removed before questioning. 
Five- and six-year-olds found both versions easy. Three- to four-year-olds performed poorly. Four- to five-year-olds performed better than chance on current trials (p=.001), but at chance on past trials (p>.999). We relate this to Hoerl and McCormack’s (2018) dual systems perspective.

Counterfactuals and mental time travel

There is an ongoing debate in the scientific community regarding the nature of cognitive flexibility. It is either seen as a general ability, a task-dependent skill, or a dimensional construct composed of reactive flexibility and spontaneous flexibility. To develop the discussion, we compared first-graders’ performance on four cognitive flexibility tasks. Two tasks focused on reactive flexibility (rule-switching and verbally-cued-switching), and two targeted spontaneous flexibility (role-shifting and divergent thinking). We also used three tests of executive functions (cognitive inhibition, working memory, and processing speed) to evaluate their link with cognitive flexibility. Significant positive correlations emerged between all but one of the flexibility tasks, regardless of whether they targeted a reactive or spontaneous use of flexibility. Similarly, confirmatory factorial analysis did not provide evidence for the dimensional structure of cognitive flexibility. These results suggest that different flexibility tasks may tap into distinct aspects of a task-dependent ability, rather than a generalized competence.

The approximate number system, involved in the estimation of large numerosities, forms the basis for the development of mathematics ability. Although researchers have investigated the cognitive underpinnings of the approximate number system, the specific underlying cognitive abilities involved need better theorisation. There have also been conflicting findings regarding the relationship between the approximate number system and mathematics ability. Therefore, the current study had twofold objectives: 1) To investigate the cognitive underpinning of the approximate number system. 2) To test whether the approximate number system can predict mathematics ability. A total of 31 primary school children participated in the study. To measure approximate number system and mathematics ability, non-symbolic number comparison and arithmetic fluency tasks were used, respectively. Using repeated measure ANCOVA and multilinear regressions, results revealed that only inhibitory control played a significant role in the approximate number system. Furthermore, the approximate number system could not predict arithmetic fluency.

The main goal of this study was to explore this adaptation of a group of Mexican people with DS aged 12-30 years during the COVID-19 pandemic. We analyze the relationships among eight domains of executive function and mental and chronological age. The participants were 50 people with DS with a chronological age (CA) of 12-30 years and a mean mental age (MA) of 7 years. MA was evaluated with Raven’s Progressive Matrices test and executive function with the Behavior Rating Inventory of Executive Function (BRIEF-2); both were administered online. The Monitor, Emotional Control, Initiative, and Organization of Materials scales showed strengths, while Working Memory, Plan/Organize, Shift, and Inhibit showed weaknesses. CA correlated negatively with seven of the eight executive domains, while MA correlated negatively with two. Participants’ executive profile during the COVID-19 pandemic is consistent with that reported in previous research, and the findings are discussed in cognitive regulation process.

Older adults can experience declines in their cognitive abilities, which could affect their ability to engage in daily activities such as driving. Here, we compare the driving habits of older adults across different cognitive groups: cognitively healthy older adults (control), Subjective Cognitive Decline (SCD), Mild Cognitive Impairment (MCI), and Alzheimer’s Disease (AD). We analyzed data from the large-scale Comprehensive Assessment of Neurodegeneration and Dementia study (COMPASS-ND, Chertkow et al., 2019). Results revealed that the AD group drove the least often and shortest distances. Interestingly, on several measures, the SCD group was more like the MCI group than the control group (driving frequency, restrictions), suggesting that even subjective declines were associated with differences in driving habits. We will further discuss how these results are influenced by sensory and demographic factors. Driving-related limitations could reduce older adults’ participation and access to essential resources, in turn, negatively affecting their physical and mental health.

As a prime step in the empirical research cycle, we rely on language to define the constituted concepts. In the plethora of scholarly output, we often find a wide range of discrepant definitions of a given concept manifested by varied linguistic expressions. Capturing the linguistic variability of de facto concept definitions helps researchers assess how convergent our understanding of a concept has become and how falsifiable the associated theory is. To estimate the falsifiability of operational definitions, we proposed and validated proxy measures using natural language processing (NLP) techniques. As a use case study, we quantified the variability of operational definitions of 216 subordinate concepts associated with "open scholarship". We aggregated 2212 operational definitions from online thesauruses and scientific texts and explored the validity of the proposed proxies of definitions' informativeness. Our study brings new perspectives on reappraising the role of language in constructing falsifiable theories.
