Dual character concepts have recently received significant attention from experimental philosophers. They are usually defined as possessing two independent criteria for categorization, each associated with its own sense. One of these criteria is descriptive, while the other is normative. Almost all examples discussed in the literature involve a positively evaluated normative element (e.g., the concept of scientist is associated with the pursuit of empirical truth, something that we value). But can dual character concepts also involve morally bad elements? We report the first evidence suggesting that they can. Our study contrasted pairs of positive and negative concepts (e.g., friend/enemy, joy/sadness) and neutral concepts (e.g., baker). We found that negatively valenced concepts such as traitor, enemy, superficial, or sadness have a dual character. We also observed that positive concepts were significantly more likely to have a dual character than negative ones, but the effect size of this difference was small.

Morality is a critical aspect of life––it influences how we think, design systems, and even the stories we tell. Looking to the popularity of true crime stories and characters like Dexter Morgan, it seems that our preferences are toward exploring moral ambiguity and moral badness. Across two experiments, we examine what moral ambiguity is and what kinds of moral information spark curiosity and explanation-seeking. In Experiment 1, we manipulate moral ambiguity to mean someone with conflicting moral character, and we predict those individuals will trigger curiosity more than morally consistent people. Results suggest that both morally ambiguous and immoral minds pique curiosity for explanations. In Experiment 2, we find that when ambiguity is instead operationalized as what is typical or average, we are curious about morally deviant things. This research points to critical differences in the kinds of moral minds we are curious to learn more about.


What is moral ambiguity and when does it trigger curiosity?

Artificial Intelligence (AI) can be harnessed to create sophisticated social and moral scoring systems – enabling people and organisations to form judgements of others at scale. While this capability has many useful applications – e.g., matching romantic partners who are aligned in their moral principles, it also raises many ethical questions. For example, there is widespread concern about the use of social credit systems in the political domain. In this project, we approach this topic from a psychological perspective. With experimental evidence, we show that the acceptability of moral scoring by AI depends on its perceived accuracy, and that perceived accuracy is compromised by people's tendency to see themselves as morally peculiar, and thus less characterizable by AI. That is, we suggest that people overestimate the peculiarity of their moral profile, believe that AI will neglect this peculiarity, and resist for this reason the introduction of moral scoring by AI.


The Quantified Moral Self

What is the relationship between trust and perceived agency? The present study experimentally investigated the effect of people’s perception of a robot’s compliance (and resistance) to social norms on their evaluation of a robot’s perceived agency, performance trust, and moral trust. Participants reported a norm-conforming robot to have higher perceived agency and a greater sense of trust than a robot that violated social norms. 
We also found that perceived agency, regardless of how much a robot followed norms, was correlated with trust. We interpret this finding as evidence that as people see a robot as having agency, they trust it more

Perceived Agency Changes Performance and Moral Trust in Robots

Dennett’s (1981) call to use computational frameworks in philosophical analysis can assist in clarifying the distinction between System-1 and System-2 metacognition. Metacognition has been described as “cognition about cognitive phenomena” (Flavell, 1979) and is renowned for its particularly difficult issues. Understanding its “mysterious mechanisms” (Brown, 1987) has been obscured by the subject’s abstractness and disputed terminology. Computation is uniquely suited to overcome these barriers as it forces definitional clarity. New research is supportive of the Common Model of Cognition as the best candidate for computationally modeling the functional organization of the human brain (Stocco et al., 2021). The Common Model represents a powerful tool for investigating unresolved cognitive issues as it is informed by a convergence of research and is well-defined. We propose that applying the Common Model as a philosophical tool can assist in clarifying the problematic distinction between System-1 and System-2 metacognition.


Clarifying Metacognition System 1 & 2 with the Common Model

The primary phenomenon within the field of collaborative memory is collaborative inhibition: the tendency for collaborative groups to underperform in free recall tasks compared to nominal groups of comparable size. Previously, we adapted the Search of Associative Memory (SAM; Raaijmakers & Shiffrin, 1981) model to collaborative free recall and found support for the retrieval disruption hypothesis (Mannering, Rajaram, Shiffrin, & Jones, 2022). In this paper, we investigate another possible cause of collaborative inhibition: memory homogenization. Previous modeling attempts have shown that memory homogenization may contribute to collaborative inhibition (Luhmann & Rajaram, 2015). In this paper, we prevent SAM models from learning during collaborative retrieval which subsequently prevents memory homogenization. We found that even when SAM model memories remained diversified, collaborative inhibition persisted—though the strength of the effect was diminished. These results suggest that both retrieval disruption and memory homogenization may contribute to collaborative inhibition in SAM.

Modeling the Effect of Learning During Retrieval on Collaborative Inhibition

Metacognition ("thinking about thinking") depends on representations and metarepresentations, which are usually treated as internal knowledge structures, rather than as external-oriented processes. We explore how multimodal patterns of external semiotic activity (not monomodal and internal symbolic-based processes) can provide a more accurate description of metacognition. To develop our ideas, we examine the act of marking-for-self in theatrical dance. To mark is to perform a dance phrase in a simplified, schematic, or abstract way. When marking, dancers use their bodies in motion to represent some aspects (properties, dynamics, or structures) of the complete dance-phrase they are thinking on. Marking-for-self occurs when dancers mark in their own idiosyncratic manner, a process that potentializes real-time reflection on its own dancing sequences and structures. According to our view, these representations are metacognitive embodied and externalized diagrammatic structures. We detail this phenomenon in light of recent developments in Cognitive Semiotics and diagrammatic reasoning approach.

Post-error slowing describes a delayed response in action after error commission. PES is a key metric of error monitoring that individuals possess self-reflective information processing, which is crucial for adaptive behaviour in learning. Studies seeking to ascertain the relationship between learning, feedback and PES remain rare. The current study aims to investigate the role task and feedback played in the magnitude of PES. Participants (N = 487, Mage = 23.77 years, SD = 5.8) performed three cognitive tasks: Flanker, Numeric and Science knowledge task. A 2 (Type of trial) × 3 (Task) × 2 (Feedback) mixed ANOVA estimated by REML was conducted; participant was treated as a random effect. We found a significant PES effect where the post-error RT is slower than the post-correct RT. We also found a significant effect of task, feedback, and Task × Feedback interaction.

Feedback-related and Task-dependent Post-error Slowing

While population-level models often provide a good fit to the data, they may mask meaningful individual differences. Exploring individual differences can also be beneficial for gaining a better understanding of the processes that underlie pragmatic phenomena. In this study, we investigate whether the substantial differences in performance on a pragmatic reference game can be traced back to cognitive or socio-pragmatic traits. We observe a significant effect of the ability to inhibit an intuitive response and of abstract reasoning ability. In contrast, we do not find evidence that socio-pragmatic abilities or working memory capacity influence pragmatic responding.

Individual Differences in a Pragmatic Reference Game

Fundamental concepts in biology are often challenging to understand. More strikingly, studies also report incorrect or incomplete understanding of such concepts for undergraduate natural science students even after instruction. Recent research suggests that embedding conceptual information in a narrative could support students’ learning process and facilitate conceptual change. Therefore, we designed learning materials covering complex concepts in biology either in the form of a narrative presenting the to-be-learned concepts in a historical context or as an expository text as control. We then assessed conceptual understanding and potential learning mechanisms. Results indicate that students learned from narrative texts and expository texts to a similar extent. However, if the prior knowledge was higher, the effect on learning was bigger in the narrative group than in the expository group. Moreover, the narrative led to better enjoyment and a higher germane cognitive load than the expository text material.


The Impact of Prior Knowledge in Narrative-Based Learning on Understanding Biological Concepts in Higher Education

Previous studies have shown that temporal metrics of writing behavior in simple transcription tasks have some potential for use in the assessment of student learning. This study explores whether spatial metrics, specifically the distance between written strokes, may also have potential for the assessment of competence. Students, N=219, copied sets of equations with different spatial layouts and equation complexity. Although students’ level of competence is manifest to an extent in distributions of distance metrics, the effects of spacing are weaker than with temporal metrics. Stimuli format contrary to the standard mathematical spacing formats may differentiate high and low competent students.
