Abstract/Results: RESULTS:
I am pleased to report a number of successes on the research stemming from this bursary, all on the general theme of quantifying uncertainty and risky decision-making across domains. We have now measured such behavior for conscious and unconscious perception in tasks ranging from intuitive physics in infants and adults, binocular rivalry, and early visual processing. Moreover, we developed a method to discover the structure of neural representations and applied it to visual cognition. This report is structured by the papers that have stemmed in part from this bursary.
[1] We investigated how people forage in an uncertain environment, and found that visual search follows optimal foraging informed by the distribution of the number of targets across displays. This indicates that people learn target distributions from the environment, and integrate this learning with uncertain, sparse measurements of the richness of a given scene, to yield near- optimal foraging behavior.
[2] Here we investigated pure reasoning about physically constrained objects in infants. We showed that a simple kinematic model can account for infants’ surprisal in a number of classic, and new, experiments measuring how infants perceive objects. This suggests that even as infants, humans can reason about physical scenarios and can combine uncertainty about object locations and motion, along with constraints from base rates.
[3] Here we asked whether bistability in the visual system during binocular rivalry might reflect optimal inference given uncertainty about the latent causes of visual input. We showed that Gibbs (or Markov chain Monte Carlo) inference in a model that captures the structured dependencies of the visual world yields both the global switching dynamics, as well as the local transition dynamics, of binocular rivalry.
[4] Here we asked whether uncertainty about the timing of rapid sequences of events is combined with expectations about the temporal structure of the world – we find that such an account can explain a number of RSVP perception phenomena, including repetition blindness, the attentional blink, and patterns of errors in those tasks.
[5] Here we proposed an overarching agenda for combining uncertain reasoning with cognitive constraints to yield rational process models. We propose that by considering optimal engineering solutions to implementing inference under uncertainty, we may develop process models of human reasoning.
[6] This is the culmination of many strands of research in which we devised methods to discover the structure of visual representations in the human brain. We applied our data driven ‘functional clustering’ to fMRI data to show that we can find which objects are seem to be subserved by similar neural substrates, and to identify neural substrates that seem to have sufficiently homogenous function. This hypothesis-neutral method of discovering functional neural architecture yields strong evidence for the face, place, and body areas, and opens the possibility for discovering new functional regions in the brain.
[7] Here we measured uncertainty in the mapping function between visually presented magnitudes, and self-reported numerical estimates. We find that mapping of magnitudes onto numbers reveals a bilinear function that highlights two regimes of (mis)calibration: small magnitudes are mapped veridically, with considerable stability. However, larger magnitudes (above about 15) are systematically mismapped, and show slow drift over time. We believe this slow drifting mismapping reflects a process of MCMC learning of the uncertain mapping from magnitudes onto our verbal number line.
[8] In this work we measured the sources of uncertainty in human physical reasoning, particularly in the domain of reasoning about physical objects undergoing simple 2D motion. We find that most of the uncertainty in these cases arises from stochastic dynamics: meaning that our forward physical models are not deterministic, but are themselves uncertain. Moreover, this physical uncertainty propagates non-linearly, and yields stable patterns of bias and error in human judgments and decisions.
[9] Here we measured uncertainty and the dynamics of verbal problem solving in a semantic remote associates test. We find that people search through their semantic space via a partially-guided random-walk, consistent with a MCMC chain exploring the semantic space weighted by the constraints of the cues.

Dynamic risk control by human nucleus accumbens

Abstract/Results: ABSTRACT:
Real-world decisions about reward often involve a complex counterbalance of risk and value. Although the nucleus accumbens has been implicated in the underlying neural substrate, its criticality to human behaviour remains an open question, best addressed with interventional methodology that probes the behavioural consequences of focal neural modulation. Combining a psychometric index of risky decision-making with transient electrical modulation of the nucleus accumbens, here we reveal profound, highly dynamic alteration of the relation between probability of reward and choice during therapeutic deep brain stimulation in four patients with treatment-resistant psychiatric disease. Short-lived phasic electrical stimulation of the region of the nucleus accumbens dynamically altered risk behaviour, transiently shifting the psychometric function towards more risky decisions only for the duration of stimulation. A critical, on-line role of human nucleus accumbens in dynamic risk control is thereby established.

Meta-analytic evidence for a reversal learning effect on the Iowa gambling task in older adults
Publication year: 2017

Abstract/Results: ABSTRACT:
Iowa Gambling Task (IGT) is one of the most widely used tools to assess economic decision-making. However, the research tradition on aging and the Iowa Gambling Task (IGT) has been mainly focused on the overall performance of older adults in relation to younger or clinical groups, remaining unclear whether older adults are capable of learning along the task. We conducted a meta-analysis to examine older adults' decision-making on the IGT, to test the effects of aging on reversal learning (45 studies) and to provide normative data on total and block net scores (55 studies). From the accumulated empirical evidence, we found an average total net score of 7.55 (±25.9). We also observed a significant reversal learning effect along the blocks of the IGT, indicating that older adults inhibit the prepotent response toward immediately attractive options associated with high losses, in favor of initially less attractive options associated with long-run profit. During block 1, decisions of older adults led to a negative gambling net score, reflecting the expected initial pattern of risk-taking. However, the shift toward more safe options occurred between block 2 (small-to-medium effect size) and blocks 3, 4, 5 (medium-to-large effect size). These main findings highlight that older adults are able to move from the initial uncertainty, when the possible outcomes are unknown, to decisions based on risk, when the outcomes are learned and may be used to guide future adaptive decision-making.

Age differences in neural correlates of feedback processing after economic decisions under risk
Publication year: 2018
URL:
https://www.sciencedirect.com/science/article/pii/S0197458018300101
Abstract/Results: ABSTRACT:
This study examines age-related differences in behavioral responses to risk and in the neurophysiological correlates of feedback processing. Our sample was composed of younger, middle-aged and older adults, who were asked to decide between two risky options, in the gain and loss domains, during an EEG recording. Results evidenced group-related differences in early and later stages of feedback processing, indexed by differences in the Feedback Related Negativity (FRN) and P3 amplitudes. Specifically, in the loss domain, younger adults showed higher FRN amplitudes after non-losses than after losses, while middle-aged and older adults had similar FRN amplitudes after both. In the gain domain, younger and middle-aged adults had higher P3 amplitudes after gains than after non-gains, while older adults had similar P3 amplitudes after both. Behaviorally, older adults had higher rates of risky decisions than younger adults in the loss domain, a result that was correlated with poorer performance in memory and executive functions. Our results suggest age-related differences in the outcome-related expectations, as well as in the affective relevance attributed to the outcomes, which may underlie the group differences found in risk-aversion.

Among its activities the BIAL Foundation manages the BIAL Award, created in 1984, one of the most important awards in the Health field in Europe. The BIAL Award rewards both the basic and the clinical research distinguishing works of major impact in medical research.
The BIAL Foundation also assigns Scientific Research Scholarships for the study of neurophysiological and mental health in people, arousing the interest of researchers in the areas of Psychophysiology and Parapsychology.
To date the BIAL Foundation has supported 461 projects, more than 1000 researchers, with research groups in twenty-seven countries, resulting, until April 2013, in about 600 full papers, out of which 172 published in indexed international journals with an average impact factor of 3.6 and a substantial number of citations (1665).
Since 1996 the BIAL Foundation organizes the Symposia entitled "Behind and Beyond the Brain", a Forum that gathers well renowned neurosciences speakers and the BIAL Foundation Fellows which are spread around the world.
Classified as an institution of public utility, the BIAL Foundation includes among its patrons the Portuguese President, the Portuguese Universities Rectors' Council and the Portuguese Medical Association.

Start date: 1994
History:
The BIAL Foundation was created in 1994 by Laboratórios BIAL in conjunction with the Council of Rectors of Portuguese Universities. BIAL’s Foundation mission is to foster the scientific study of Man from both the physical and spiritual perspectives.
Along the years the BIAL Foundation has developed an important relationship with the scientific community, first in Portugal and after worldwide. Today it is an institution of reference which aims to stimulate new researches that may help people, promote more health and contribute to new milestones to gain access to knowledge.
Among its activities the BIAL Foundation manages the BIAL Award, created in 1984, one of the most important awards in the Health field in Europe. The BIAL Award rewards both the basic and the clinical research distinguishing works of major impact in medical research.
The BIAL Foundation also assigns Scientific Research Scholarships for the study of neurophysiological and mental health in people, arousing the interest of researchers in the areas of Psychophysiology and Parapsychology.

Title: BIAL Grants
Start date: 1994
History:
In 1994 the BIAL Foundation launched a programme of science research grants with the aim of encouraging the research into Man’s physical and mental processes, namely in fields still largely unexplored but which warrant further scientific analysis, as Psychophysiology and Parapsychology.
Since its launch, applications to the BIAL grants have been increasing. Up to now 461 projects have been supported, involving more than 1000 researchers from 27 countries.
The approved applications have benefited from grants in amounts comprised between €5,000 and €50, 000. The amount to be granted is fixed by the Scientific board according to the needs of each project.
The supported projects have originated, until April 2013, in about 600 full papers, 172 out of which were published in indexed international journals with an average impact factor of 3.6 and a substantial number of citations (1665).
Among the BIAL Foundation fellows is worth highlighting the presence of scientists from prestigious universities from the United States, United Kingdom, Australia, Russia, Germany, Japan, France, Canada, and many others.
The BIAL grants are promoted biannually.
