Dr Laura Corbit (University of Toronto)Bio
I received my PhD from UCLA where I worked with Bernard Balleine studying the neural circuits underlying goal-directed learning. I completed my postdoctoral training in the lab of Patricia Janak at the Ernest Gallo Clinic and Research Centre where I studied how exposure to alcohol altered behavioural control. From there I moved to the School of Psychology at the University of Sydney where I was a Lecturer/Senior Lecturer until 2017 when I moved to the University of Toronto where I am currently an Associate Professor in the Department of Psychology.
My lab continues to study the behavioural and neural control of instrumental learning and reward-seeking behaviours. We are particularly interested in the role of different types of behavioural control and how they are acquired, as well as how life experiences such as diet or exposure to drugs alters learning and behaviour.
Understanding the effects of diet on decision-making and the neural circuits underlying behavioural control
Abstract
Habits provide a rapid, efficient means for decision making however, this comes with a loss of behavioural flexibility. Although striatal circuits are involved in habit learning, little is known about how experiences that accelerate habit learning alter activity in these circuits to promote premature habitual control. Using the outcome devaluation task to distinguish flexible actions from habits, we have found that long-term access to an obesogenic diet promotes habitual behavioural control. I will present data that demonstrate changes to glutamate transmission and microglial activity following the obesogenic diet, pharmacological reversal of which restored goal-directed control. These results have important implications for understanding failures of behavioural control and strategies for improving behavioural flexibility.

Circadian Depression: Testing a pathophysiological pathway to mood disorders
Abstract
Much of our everyday sense of well-being is driven by a well functioning 24-hour sleep-wake cycle, underpinned by the physiology of our body clock – or circadian system. Much progress has been made over the last two decades in unravelling the complex brain and body mechanisms that align the function of that clock with the external light-dark rhythms, and the changes in those rhythms that occur regularly across seasons and across the normal developmental life cycle. Our group at the Brain and Mind Centre actively investigates the ways in which dysfunction of those clock mechanisms may give rise to particular types of mood disorders characterized by low energy, prolonged sleep, weight gain and reduced motor activity. Of particular interest is the ways in which these states may also switch to an opposite phenotype of high energy, increased motor activity and low sleep. The importance of identifying these types of mood disorders, and designing specific behavioural and pharmacological approaches to care, will be discussed.

Humorous Denials
Abstract
Every day people deny rumors and accusations of wrongdoing. Their denials typically take a serious tone (e.g. I did not have sexual relations with that woman – Bill Clinton), however some denials are intended to be humorous. From Chrissy Teigen’s hilarious clapbacks to photoshop accusations; celebrity surgeon Munjed Al Muderis jokingly dismissing claims about inflicting his patients with maggot–ridden wounds; to WWE champion Randy Orton laughing off claims of sexual misconduct, humorous denials have attracted significant attention. This paper introduces the concept of humorous denials and examines the benefits and dangers of being humorous when denying an accusation. Across five studies we show that in contrast to the belief that a humorous response will help make a denial seem more credible, a humor attempt in fact increases suspicion of wrongdoing. However, while using humor to deny an accusation may harm deniers by heightening suspicion of wrongdoing – we show that, ironically, it may also benefit the denier by reducing anger and subsequent punishment when the denial is subsequently exposed as a lie. This research not only establishes the novel role of humor in denials, but it is the first to examine the unexplored interplay between humor and deception. Our findings suggest a trade-off of implications for individuals and companies managing high-stake reputations and brand relationships.
This research is conducted in collaboration with Associate Professor Caleb Warren (University of Arizona) and Professor Peter McGraw (University of Colorado).

A/Prof Lisa Williams (UNSW)Driving EDI with data: How data-driven approaches can advance equity in the STEM sector
Abstract
Advancing equity, diversity, and inclusion is a moral and operational imperative in today’s society, especially in the STEM sector. Establishing what to do to shift the dial in this space, and evaluating if it’s working, is essential yet often overlooked. This talk will cover several projects that leverage data to design, garner support for, and advance initiatives for equity, diversity, and inclusion at the university, sector, and national levels. These projects include data-driven design and evaluation of initiatives within the UNSW Faculty of Science, including the UNSW Women in Maths and Science Champions Program. Other examples include those conducted in A/Prof Williams’ capacity as Chief Investigator on the grants that fund Australia’s Women in STEM Ambassador initiative: (1) an analysis of 20 years of ARC and NHMRC grant outcomes data by gender of the lead investigator, (2) a trial of anonymising peer review for grant applications for access to scientific equipment, and (3) a series of systematic reviews on the efficacy of workplace initiatives to support gender equity, disability inclusion, and inclusion of sexual and gender minority populations. How such approaches can be effectively leveraged to advise on policy and practice at governmental and organisational levels will be discussed.

Dr Llew Mills (USYD)What works and why: two approaches to the treatment of addiction
Abstract
Addiction affects everyone, either directly through their own struggles or indirectly through the struggles of their friends and family. Yet it remains one of the most challenging disorders to treat. Medical addiction research tends to be pre-occupied with what treatments work and for whom, whereas theoretical addiction research attempts to ask why these treatments work. Dr Llew Mills from the Specialty of Addiction Medicine, University of Sydney discusses the pros and cons of these two different approaches, first via a tour through his more theroretical PhD work examining the cognitive processes that affect caffeine withdrawal, and second via a discussion of some of the studies he has run as a postdoc at the Faculty of Medicine: testing efficacy of a cannabis agonist drug for people with cannabis use disorder; determining what factors are associated with cannabis use disorder among medical cannabis users; and examining whether methamphetamine use at outset of treatment is associated with poorer outcomes among clients enrolled in an opioid treatment program.

Psychology Colloquium: A/Prof Vincent Laurent

A/Prof Vincent Laurent (UNSW)Cholinergic regulation of fear by the basal forebrain
Abstract
The basolateral amygdala (BLA) and the infralimbic (IL) region of the medial prefrontal cortex are heavily implicated in fear regulation. These two regions receive dense cholinergic projections from the nucleus basalis of Meynert (NBM) and/or the horizontal limb of the diagonal band of Broca (HDB), which are both located in the basal forebrain. The present experiments examined whether these projections regulate the formation and extinction of fear memories, as well as the capacity of these memories to renew when context cues are manipulated. This was achieved by employing a Pavlovian fear protocol and optogenetics in transgenic rats. Silencing NBM-to-BLA cholinergic projections during fear conditioning weakened the fear memory produced by this conditioning and eliminated its renewal after extinction. A similar outcome was obtained when silencing HDB-to-BLA or HDB-to-IL cholinergic projections during extinction. These findings indicate that basal forebrain cholinergic signalling in the BLA and IL plays a critical role in fear regulation by promoting strength and durability of fear memories. This leads to the proposal that the function of basal forebrain cholinergic signalling is to protect fear memories from erasure when they are extinguished.

Psychology Colloquium: Dr Erin Goddard
2024-05-03 15:00 - 16:00
Dr Erin Goddard (UNSW)Visual feature binding and colour constancy: similar processes?
Abstract
Different regions in visual cortex show specialisation for encoding different visual features, giving rise the question of how these features are ‘bound together’ to create a unitary percept of each object. I will show recent work based on classification of magnetoencephalography (MEG) data where we found that information about separate colour and shape information preceded information about their conjunction in occipital cortex. This may reflect feedback to occipital regions being required for feature binding, which would be consistent with a role for attention, as suggested by behavioural work (e.g. visual search). While this ‘binding problem’ has been investigated for at least 30 years, more recently I investigated whether a process similar to feature binding might be involved in the separation of surface and illuminant properties in colour constancy. I will present behavioural work where we tested this idea, and found that, like feature binding, the perceptual separation of surface and illuminant properties appears to rely on a slower, limited capacity process.

Prof Carolyn MacCann (USYD)Emotional intelligence and emotion regulation
Abstract
The way we deal with emotions is important for our well-being, social relationships, and performance at work and school. This talk focuses on two key concepts that affect how we deal with emotions: emotional intelligence and emotion regulation. Emotional intelligence is a set of skills or capacities you have, usually defined as the ability to accurately perceive, understand, and regulate emotions. Emotion regulation is the process by which you influence the type and intensity of emotions that you or others feel and express. In this presentation, I will discuss evidence from meta-analyses and empirical studies linking emotional intelligence, emotion regulation, and life outcomes. This includes a large-scale meta-analysis on the relationship between emotional intelligence and academic performance (k = 1,246, N = 42,529) and emerging research on how people regulate others’ emotions (extrinsic emotion regulation). I will present a framework for the strategies people use to regulate others’ emotions, and consider cultural differences in these strategies and their effects.
Bio
Carolyn MacCann is a Professor in the School of Psychology at The University of Sydney. Her research addresses how emotion-related characteristics lead to work success, educational success, and greater mental health and well-being. Two major concepts in her research are emotional intelligence abilities and emotion regulation processes. She develops psychometric tests to assess these and other related concepts. She also focuses on the mechanisms and pathways by which emotional intelligence and emotion regulation lead to life success. Her research tends to be cross-disciplinary, cutting across psychology, education, and business.

Dr Eliane Deschrijver (USYD)Unequal resource division occurs in the absence of group division and identity
Abstract
The seminal minimal group experiment has shown that discrimination can follow from intergroup relations and social identity. A large body of research evidenced that people discriminate against members of their out versus ingroup, even if groups and identities were assigned on the basis of one’s dot guessing style, aesthetic judgement or a chance outcome. But is group and social identity assignment required for unequal resource division to arise here? We show via Bayesian models in 6 pre-registered experiments (>900 subjects) that unequal resource division strategies persist against a single person that demonstrates a different versus the same quantity estimate, painting preference, or even coin flip (Experiments 1-3), with 43.1% more money awarded for sameness relative to difference conditions (Experiments 4-6). These findings open up the possibility that one key driver of discrimination may exist in a neural mechanism of interindividual comparison that treats difference more negatively than sameness. Theoretical implications, ongoing work, and future aspirations for understanding cognitive and brain systems of discrimination will be discussed.

Dr Eliane Deschrijver is a senior neuroscientist and a DECRA fellow at the University of Sydney. She works on the nexus of social neuroscience, experimental psychology, philosophy of mind and social psychology, and has an added interest in sociology. Over the past few years, her thinking has focussed on how the brain processes a difference between one’s own world view and that of another person, independent of what the disagreement is about. She has theoretically argued that such a difference may come with a conflict signal in the brain, which is negatively valenced and may lead to behavioral change. She is now investigating what this concept of “sheer difference” may mean for our understanding of discrimination. Breaking with the singular focus of social neuroscientists on the brain, she believes that the most thorny social-cognitive scientific issues deserve an exceedingly interdisciplinary future approach, in particular by enticing philosophers of mind and social psychologists into the debate.

Prof Michael Bowen (USYD)Title: KNX100 and other small molecules that could: Developing prosocial compounds for disorders of the brain and mind
Abstract: Challenges with social motivation, interactions, and communication are central to many disorders of the brain and mind, and are major barriers to improved functioning in others. For example, in substance use disorders, impairments in social functioning can hinder successful engagement in programs where social factors are crucial, such as the Community Reinforcement Approach and Alcoholics Anonymous. Despite their pervasiveness, there are no approved pharmacotherapies specifically targeting social symptoms. KNX100 is a novel, now clinical-stage small molecule, discovered at the University of Sydney through a phenotypic screen that identified its prosocial effects and modulation of social circuits in the brain. KNX100 is being developed by the University of Sydney spinout company, Kinoxis Therapeutics, in close partnership with the University under a major multi-year research partnership. In preclinical models, KNX100 is showing transdiagnostic potential for treating substance use disorders, and for reducing agitation and aggression in neurological and psychiatric conditions. KNX100’s novel mechanism of action involves inhibiting neuronal hyperactivity in the nucleus accumbens shell and increased activity in the prodynorphin-dynorphin-kappa opioid receptor pathway in this brain region, a system at the nexus of motivation, socioemotional behaviour, and stress. Current programs are exploring KNX100’s clinical efficacy for treating several substance use disorders, and agitation and aggression in dementia. In its other major program, Kinoxis has partnered with multinational pharmaceutical company Boehringer-Ingelheim to discover and develop, in close partnership with researchers at the University, novel small molecules targeting the oxytocin receptor, one of the most important social systems in the brain.

Prof Ben Newell (UNSW)Title: The many uncertainties of climate change: A psychological perspective
Abstract: The one thing that is certain about climate change is that it is happening. The extent of its impacts, our ability to adapt, to mitigate and to plan are, however, all inherently uncertain. This is unfortunate because uncertainty can often cloud perception and undermine action. In this talk I will present work examining variants of uncertainty that have relevance for understanding psychological reactions to climate change. This includes experiments assessing how the projections of climate models are interpreted, how uncertain thresholds affect decisions in simulated climate negotiations, and how climate risk information affects judgments in simulated online property searches. The diversity of these problems highlights the challenges faced by any single discipline in addressing the challenges of climate change. I will advocate for the importance of interdisciplinary approaches and illustrate how such collaborations can precipitate policy, and ultimately behavioural change.

Prof Andrew Lawrence (Florey)Title: Muscarinic Acetylcholine Receptors as a Novel Treatment Target for Alcohol Use Disorder
Abstract: Despite the large socioeconomic burden of alcohol use disorders (AUD), therapeutic treatment options are limited. There is a need to characterise the underlying neurochemistry driving alcohol seeking to identify and evaluate novel treatment targets. To this end we conducted genome-wide RNA sequencing in the striatum from humans with AUD and healthy controls and concurrently examined receptor expression in the corresponding brain regions in rat following chronic alcohol consumption/withdrawal. In the brains from humans with AUD we found reduced expression of muscarinic M4 receptors, which was limited to the putamen. In line with this, expression of the same receptor was decreased in the rat dorsolateral striatum (plus other regions). These findings have been extended to mouse striatum by a collaborating laboratory. Further, administration of an M4 Positive Allosteric Modulator to target M4 receptors reduced alcohol self-administration and relapse, without effects on natural reward consumption or sedation. Collectively, our data identify a novel treatment target for AUD. We are in the process of trying to translate this finding.

Dr Jelena Brcic (University of the Fraser Valley)Title: Reported Psychological Growth Following Work in Extreme and Unusual Environments: Role of Perceived Stress and Coping
Abstract: There are psychological, biological, and sociological constructs that emerge within extreme and unusual environments (EUE) that cannot be studied elsewhere. Post-Experience Change (PEC), which is significantly modelled after Post-Traumatic Growth (PTG), is one such aspect. PTG it is defined as a positive psychological change as a result of psychological struggle ensuing trauma. Changes can be experienced in perceptions of self, changes in interpersonal relationships, and in the meaningfulness of life (Tedeschi & Calhoun, 1996; Triplett et al., 2012). We believe that prolonged experiences in EUEs, which are not traumatic but are meaningful, can have a positive impact and lead to life changes experienced by expedition members.
To understand the full deployment experience, growth possibilities, and to identify the situational impact on the personnel in EUEs, a study of stress perception and coping strategies is essential. Work in this domain of stress and coping has been plentiful across many EUEs (Leon, Sandal, & Larsen, 2011; Nicolas et al., 2013; Suedfeld et al., 2009, 2012, 2015).
This presentation will examine stress, coping, and PEC in expedition members from three different EUE groups: long-duration astronauts, winter-over crew working on an Environment Canada weather station in Ellesmere Island, Nunavut, and rescue teams from BC Search and Rescue and Royal Canadian Search and Rescue organizations. Discussion will be around the impact of mission duration, the extremeness and uniqueness of the environment, and the type of positive impact the experiences had on expedition members.

Prof Paul Rhodes (USYD)Title: Eco-psychology: a critical paradigm in the climate emergency
Abstract: This presentation makes the argument that mainstream psychological practice is not equipped to respond to distress associated with the climate emergency. This is because the field focusses on individual pathology, rather than ecological context. It remains reticent about activism and politics and is ontologically aligned with the Anthropocene, a new era in which the human species is creating an observable effect in the geological record, to the detriment of the planet and its life forms. An introduction is provided to ecopsychology, its history and philosophy, a movement that has sought to subvert and transform mainstream psychology over the last three decades. Ecopsychology still offers an opportunity for mainstream psychology to alter its approach in the face of the climate emergency. Six studies conducted by the Ecological Emotions Research Lab will be presented as exemplary of eco-psychological inquiry.

Dr Will Harrison (University of the Sunshine Coast)Title: Seeing More with Less: Efficient sensory coding with and without eye movements
Abstract: It is often difficult to understand perceptual and cognitive processes from a scientific point of view. Unfortunately, I think we often mistake our difficulty in understanding a problem with the complexity of the problem itself. For example, it may feel intuitive to conclude that the brain must use complex algorithms to coordinate action and perception solely because we, as scientists, have difficulty understanding how such phenomena come about. But what if the brain is much simpler?
Recently I’ve been trying to understand the minimum computational requirements for various perceptual and cognitive tasks. Efficient coding theory tells us that nervous systems should use as few resources as possible to convey the most amount of information. Put differently, the brain is lazy: if one neuron can code two pieces of information with high fidelity, it would be wasteful to have this information replicated by a second neuron. By combining ideas from efficient coding with psychophysical experiments and computational modelling, I have found efficiencies within the mammalian visual system that promote perceptual inference, with and without eye movements.
Bio: Dr Will Harrison is a cognitive neuroscientist who is interested in how the brain transforms visual information into conscious thoughts and memories. He received his PhD in Psychology from the University of Queensland in 2013, and has completed postdoctoral fellowships at Harvard Medical School, the University of Cambridge, and the Queensland Brain Institute. He has published dozens of papers in top international journals, focusing on how people perceive and remember objects in their peripheral vision, how eye movements affect what we see, and how the human brain uses the structure of natural environments to guide perception. Dr Harrison uses a variety of methodologies, include psychophysics, neuro-imaging, and computational modelling.

Dr Will Ngiam (University of Adelaide)Title: Multivariate decoding of visual attention and memory – is what we see, what we remember?
Abstract: The ability to select relevant information and maintain it in mind – our attention and working memory respectively in broad strokes – is central to perception and cognition. In hopes of better understanding of these processes, philsophers, cognitive psychologists and neuroscientists have been trying to model how inforation is represented in mind and brain.
My talk will focus on two deceptively simple questions: what is a visual object and how are they remembered? First, I will provide a brief overview of multivariate classification of neuroimaging data with machine learning – a trending analysis method that has shown promise in unveiling representations in the brain. I will present two EEG research projects using this method – the first involves understanding how the features of a moving object are remembered, and the second involves how our learning and experience influence how we represent items in mind.
Bio: Will is an alum of the School of Psychology, completing his undergraduate Honours degree here before his PhD with Alex Holcombe in 2019. He went abroad for his postdoc, working with Edward Awh and Edward Vogel at the University of Chicago, before recently returning back to Australia and joining the University of Adelaide as a Lecturer. Will has started the Perception, Attention, Learning and Memory (PALM) Lab, where he hopes to design novel psychophysical experiments to inform computational models of attention and memory and linking those models to patterns of neural activity – all in the hopes of better understanding human cognition.

Prof Virginia Slaughter (UQ)Title: Do humans imitate from birth?
Abstract: Imitation in human newborns is widely cited as evidence of an inborn Mirror Neuron System that underpins human social behaviour, even though its existence has been debated for decades. The possibility that newborns do not imitate was reinvigorated in recent years by research from our lab at the University of Queensland. In this talk I will present original data from the largest-ever longitudinal study of newborn imitation and the first-ever meta-analysis. I will also discuss findings from infant EMG experiments which further challenge the claim that newborn humans can imitate. All of this leads to alternative accounts of the development of imitation and its role in human sociality.

Dr Christina Perry (Macquarie University)Title: “Incubation of Craving” – investigating changes to brain and behaviour during alcohol abstinence in rats
Abstract: Alcohol-associated cues can produce intense craving in people with alcohol use disorder, which in turn can lead to relapse. Such cues may come in the form of advertising, places where a person used to drink, or indeed any environmental stimulus that may have been present during prior drinking. These episodes of cue-driven craving are reported to increase in intensity over the first months of abstinence, a phenomenon termed “incubation of craving”. Neural mechanisms of incubation have been reasonably well-researched in rodent models of psychostimulant drug relapse, however almost no studies have looked at this in the context of alcohol. Our research seeks to meet this gap by training rats to lever press for alcohol, and then measuring changes in cue-induced relapse to alcohol-seeking across a four week abstinence period. We have conducted whole-brain analysis of neural activation and preliminary neural tract tracing, as well investigating the psychological mechanism for the time-dependent increase in alcohol-seeking. In addition, we are researching ways of reducing the increase in relapse propensity, including through voluntary wheel-running exercise. The aim of this project is to be able to identify risk factors for relapse following intervention for alcohol use disorder, as well as develop long-term strategies to reduce this risk.
Bio: Christina Perry is a senior lecturer and research fellow at Macquarie University. She completed my PhD in Behavioural Neuroscience at the University of New South Wales, before moving to Melbourne to work as a post-doc in the Behavioural Neuroscience division at Florey Institute of Neuroscience and Mental Health, working with Andrew Lawrence and Jee Hyun Kim. Her primary research interest has always been addiction, particularly why relapse is such a pervasive problem for substance use disorders. In 2015 she was awarded an early career fellowship from the Society for Mental Health Research, then in 2016 a dementia research development fellowship from NHMRC/ARC. These allowed her to develop an independent program of research, looking at how chronic alcohol use interacts with the normal cognitive changes that occur with ageing, and how this impacts on the prospect of rehabilitation. In 2021, she moved back to Sydney, to work with Prof. Jen Cornish at Macquarie University. She currently leads two major government-funded projects that seek to understand the neurobiology of substance use disorder, and of regulation of defensive responses. Her research uses complex behavioural paradigms combined with sophisticated neuroscience techniques to understand the biological basis of motivated behaviour.
