We report evidence of sound symbolism for the abstract concept of time across seven experiments (total N = 825). Participants associated the future and past with distinct phonemes (Experiment 1). In particular, using nearly 8000 pseudowords, we found associations between the future and high front vowels and voiced fricatives/affricatives, and between the past and /θ/ and voiced stops (Experiment 2). This association was present not only among English speakers but also by speakers of a closely related language (German) and those of a more distantly related language (Hungarian; Experiment 3). This time-sound symbolism does not appear to be due to embodied articulation (Experiment 4). In sum, these studies identify a robust time sound symbolism effect, along with tests of underlying mechanisms.

Moral injury is a potentially deleterious mental health outcome that can result from exposure to morally challenging events. Treatment of moral injury is currently hindered by incomplete understanding of its underlying mechanisms. Theories of adaptation posit that maintaining a coherent sense of self while realigning one's sense of self with reality aids in adaptation following a disruptive life event. Differences in identity processing style are thought to impact the extent to which an individual engages with the challenges of maintaining a coherent sense of self following identity-related challenges. However, little is known about how identity processing style relates to moral injury event-related distress. This study sought to investigate a hypothesized relationship between identity processing style and event-related distress as well as alternative outcomes including traumatic stress, depression and anxiety. Adults (N = 167) who had been exposed to a potentially morally injurious event were recruited online and completed validated measures of event-related distress, traumatic stress, depression, anxiety and identity processing style. There were significant positive associations between diffuse-avoidant processing and all mental health outcomes, no significant associations between informational processing and any mental health outcomes, and significant negative associations between normative processing and event-related distress and depression.

In this research, we investigated individual differences in the formation and persistence of causal illusions. In a re-analysis of existing data, we identified two clusters of participants - persistent and adjusting - based on their trajectories in learning from repeated exposure to null contingencies. The persistent cluster maintained stable causal illusions, while the adjusting cluster demonstrated a reduction over time. This re-analysis provided a nuanced understanding of individual differences in causal learning, emphasizing the differential role of probability estimations in predicting causal judgements. These findings were replicated in a subsequent study, highlighting the robustness of the identified effects. In a pre-registered study, we extended the paradigm to include a second phase (active phase) to assess how individual differences in causal illusion trajectories in the passive phase would manifest when participants had agency in the information gathering process. The results were consistent with those of the two previous studies and confirmed our primary hypothesis that the adjusting cluster would exhibit a lower tendency to introduce the candidate cause on learning trials, and would, therefore, observe a higher frequency of cause-absent trials. Together, these studies provide comprehensive insights into the underpinnings of causal illusion development and persistence, potentially informing de-biasing interventions.

Advances in Artificial Intelligence (AI) have made significant strides in recent years, often supplementing rather than replacing human performance. The extent of their assistance at the highest levels of human performance remains unclear. We analyse over 11.6 million decisions of elite chess players, a domain commonly used as a testbed for AI and psychology due to its complexity and objective assessment. We investigated the impact of two AI chess revolutions: the first in the late 1990s with the rise of powerful PCs and internet access and the second in the late 2010s with deep learning-powered chess engines. The rate of human improvement mirrored AI advancements, but contrary to expectations, the quality of decisions mostly improved steadily over four decades, irrespective of age, with no distinct periods of rapid improvement. Only the youngest top players saw marked gains in the late 1990s, likely due to better access to knowledge and computers. Surprisingly, the recent wave of neural network-powered engines has not significantly impacted the best players - at least, not yet. Our research highlights AI's potential to enhance human capability in complex tasks, given the right conditions, even among the most elite performers.

This study investigates the optical information for visual event perception. Events are objects in motion, with properties like shape, weight and surface material influencing the dynamics that shape movements and optics. The progressive transformation of visible textures, known as visual kinaesthetic information, specifies movements and objects. Four experiments tested whether events could be perceived using only visual kinaesthetic information. Participants identified their own walking from point-light displays (Experiment 1), from simulated environmental texture transformations as a result of their walking (Experiment 2), and from videos shot by a head-mounted camera during outdoor walking (Experiment 3); and distinguishing strangers from footages captured by their head-mounted cameras (Experiment 4). In Experiments 2–4, the displays did not resemble the outline of a person or look like walking but revealed the physical relations between the walker and the environment as a result of their movement. Regardless, participants were able to recognize themselves and distinguish strangers. Thus, observers are able to perceive events using visual kinaesthetic information that stems from dynamics. The one-to-one correspondences between object property, dynamics, kinematics and optical information are governed by the laws of physics, and unaffected by the event's appearance or viewing perspectives.

Spontaneous mind wandering has been implicated as a feature of attention-deficit/hyperactivity disorder (ADHD) and researchers have wondered if spontaneous remembering is also a feature of ADHD. In this study, we compared spontaneous cognition, principally involuntary autobiographical memories, in participants who scored inside the ADHD range on BAARS-IV to those who scored outside of the ADHD range. In Study 1, participants reported their involuntary memories and spontaneous thoughts on a laboratory measure of involuntary memory (the vigilance task), as well as estimated their daily involuntary memory frequencies on a separate questionnaire. The results showed that ADHD range participants did not differ from non-ADHD range participants in reports of involuntary memories and spontaneous thoughts on the vigilance task, but ADHD range participants estimated higher daily involuntary memory frequencies than non-ADHD range participants on the questionnaire. Additionally, on the questionnaire, ADHD participants reported that their involuntary memories were less positive and more repetitive than non-ADHD participants. In Study 2, participants recorded their naturally occurring involuntary memories in a structured diary for 48 hours. The results showed that ADHD range participants had more involuntary memories than non-ADHD range participants, and they also reported that they experienced them as less positive.

We present three experiments to study the effects of giving information about the decision of an automated face recognition (AFR) system to participants attempting to decide whether two face images show the same person. We make three contributions designed to make our results applicable to real-word use: participants are given the true response of a highly accurate AFR system; the face set reflects the mixed ethnicity of the city of London from where participants are drawn; and there are only 10% of mismatches. Participants were equally accurate when given the similarity score of the AFR system or just the binary decision but shifted their bias towards match and were over-confident on difficult pairs when given only binary information. No participants achieved the 100% accuracy of the AFR system, and they had only weak insight about their own performance.

This study investigated whether structural similarities (i.e. abstract frames, e.g. once bitten twice shy) can prevail over surface similarities (i.e. contexts, e.g. restaurant) in driving the retrieval of realistic events involving dynamic, multimodal and perceptually crowded data. After watching an initial set of video clips, participants had to indicate whether a new video clip, that shared surface similarities with an initial event and structural similarities with another one, elicited a retrieval. The results of Experiment 1A showed that retrieval was more likely to be elicited by structural rather than by surface similarities. Experiment 1B confirmed that the surface similarities manipulated in this study were strong enough to elicit substantial retrievals when the competing structural match was neutralized. The pattern of results obtained in Experiment 1A remained unchanged when the number of unrelated video clips within the initial set was increased. The findings suggest that structurally based retrievals still prevail when familiar structures underlie realistic perceptual events. They open new perspectives regarding the settings that promote structurally based retrievals in educational contexts where unfamiliar principles are introduced.

Interventions for increasing self-compassion are typically assessed through retrospective reports, which may not accurately capture everyday self-compassionate behaviour. Our study addresses this using experience sampling to evaluate a brief compassion-focused intervention's effects on needs for self-compassion, awareness of opportunities for self-compassion, self-compassionate behaviour and emotional responses to one's distress in daily life. Results indicated that the intervention was associated with less likelihood of reporting needs and opportunities for self-compassion but with no difference in self-compassionate actions or emotional experience. When participants acted self-compassionately, they reported more positive emotional experiences after needing self-compassion. This underscores the disparity between retrospective and ecological assessments, emphasizing the need for interventions to be evaluated in real-life contexts.
