Title: Measurements of perceived time of visual events
Abstract: Visual perception is not instantaneous. It takes a few milliseconds for light to be transduced in photoreceptors and tens of milliseconds more for neuronal spikes to occur at successive levels of the visual hierarchy. These delays necessarily impact our abiity to perceive time. I will present examples of human time perception from two classes of tasks, duration estimation and perceived time of an event. In duration estimation, we have shown that observers are able to estimate the duration of an interval even when the onset of that interval is not explictly provided. In perceived time, we have shown that the perceived time of an event is influenced by other events in their temporal proximity, and that this perceived time varies across the visual field. A better understanding of our sensitivity to and biases in the perception of time is important to fully appreciate how well we understand our sensory environment.

Title: Hunter-Gatherer Social Organisation and Behaviour: Implications for Mental Health
Humans lived as hunter-gatherers for the vast majority of our species' history. Therefore, research with contemporary hunter-gatherer societies can offer insight into the evolution of our psychology and physiology. Drawing on my fieldwork with BaYaka hunter-gatherers from Congo, I will discuss the selection pressures that have shaped human social cognition and behaviour. I will focus on the communal living arrangements, egalitarian social organisation, and extensive cooperation, particularly in the domain of childrearing, which are normative across contemporary hunter-gatherer populations. I will also discuss how deviations from these features of sociality, which are commonplace in high-income industrialised societies, may increase our vulnerability to mental health disorders due to evolutionary mismatch-when an organism faces conditions that differ from those that some trait of the organism is adapted to, resulting in pathology or maladaptation.

ABSTRACT |Visual statistical learning (VSL) describes how humans automatically and implicitly become sensitive to the statistics of visual input in the absence of supervision or reinforcement. Research on VSL usually focuses on learning either temporal or spatial regularities and almost always excludes the influence of prior knowledge. In this dissertation, I present a reconceptualization of VSL as part of a larger human unsupervised learning system operating by combining lower-level spatio-temporal co-occurrence statistics and higher-level top-down biases. I identified three types of higher-level biases affecting statistical learning: (1) pre-existing biases independent of properties of the experiment, (2) biases formed based on the abstraction of learned low-level statistics, and (3) biases based on observed higher-level features of the input. Furthermore, I identified important moderators of this hierarchical learning system: explicit-ness and consolidation of knowledge.
Extending the classical spatial VSL paradigm to a transfer learning paradigm, I found that while participants with explicit knowledge could immediately abstract from their acquired representations and generalize to novel input, participants with implicit knowledge showed a structural novelty effect in immediate transfer. This means they were better at learning novel input that was not aligned with what they had learned before. However, after a period of asleep consolidation, participants with implicit knowledge switched their behavior and showed generalization, as the participants with explicit knowledge did before. Using control experiments, I confirmed that this effect is specific to sleep and could not be explained simply by time passing or a time-of-day effect. Furthermore, using matched sample analysis, I demonstrated that differences in the strength of initial learning cannot explain the qualitative differences found between participants with explicit and implicit knowledge.
In order to combine the previously disjoint lines of spatial and temporal VSL, I developed a novel spatio-temporal visual statistical learning paradigm. There, spatially defined patterns were unfolding to the observer over time. I demonstrated that implicit learning is possible for spatio-temporal input and provided experimental evidence that the temporal statistics of the input were used for the implicit acquisition of spatial patterns. Furthermore, I showed that when confronting participants with the complexity of spatio-temporal input, top-down, bottom-up interactions naturally emerged, linking this line of research with the VSL transfer learning paradigm described above. I found that both the overall motion direction and the overall arrangement of shapes can bias participants learning and their beliefs about what types of structures are present in the input. Furthermore, by combining the spatio-temporal VSL paradigm with a prediction task, I found that participants with explicit knowledge but not participants with implicit knowledge can use it for prediction, adding to the findings on differences between explicit and implicit representations described above.
Overall, this dissertation demonstrates that the narrow limitation and control that enabled the initial success of VSL research need to be carefully and incrementally overcome to understand the role of VSL in the overall human cognitive system. It does so by introducing two new VSL paradigms that enable novel, systematic ways of investigating the human unsupervised learning system.

ABSTRACT |To become competent social agents, young children must make sense of the frequently opaque behaviors of other people and draw appropriate conclusions from them. This dissertation is about how infants and children understand other agents' instrumental and social actions (specifically, helping) by using a naive utility calculus, and the inferences they make from observed interactions to character traits. It comprises three sections. Section 1 addresses whether infants possess a concept of choice, and use it to generate the expectation that a goal-directed agent will choose the best of multiple available
options, meaning the one that yields the highest rewards or requires the least cost to bring about. We argue that this capacity is a precondition for a mature understanding of helping, as the latter requires comparing the action options of the Helpee (contingent on whether or not she receives help) and the Helper (insofar as her options relate to the Helpee's outcome). To probe whether infants can compare alternatives of varying utility, we conducted a set of looking-time and eye-tracking experiments testing whether they think an agent should approach a relatively higher number of goal objects, or a goal that
can be reached at relatively lower effort. Section 2 explores infants' and children's understanding of helping actions. Specifically,
we ask whether they possess a utility-based concept of helping whereby the goal of a Helper is to increase the utility the Helpee obtains in reaching her goal. To approach this question empirically, we ran a series of looking-time experiments with infants, as well as an experiment with preschoolers probing what they mean by the term "helping". We also report a replication attempt of Hamlin et al.'s (2007) finding that infants prefer Helpers, a paradigm often used to probe their understanding of helping actions.
Finally, Section 3 investigates whether children interpret third-party social interactions by spontaneously ascribing character traits to agents, and choose partners for their own cooperative endeavors accordingly. While it has been argued that young children, upon observing helping events, ascribe a stable prosocial disposition to a Helper, we maintain
that it is unclear whether they do so spontaneously. We developed a tablet-based collaborative foraging game where the player first observes agents differing in helpfulness and skill, subsequently selects one of the previously seen agents as a partner, and plays together with the chosen partner. We used this game to study partner choice in 5- to 10- year-old children and adults across two cultural contexts (Hungary/Austria and Japan). The research described in this dissertation thus aims to shed light on the mechanisms of early action understanding (i.e., whether infants consider alternative possible goals), test whether a hierarchical action representation and naive utility calculus underlie young children's reasoning about helping behaviors, and investigate to what extent the observation of cooperative interactions from a third-party perspective prompts children
to infer traits and informs their own social decision-making.
