Biological psychology and cognitive neuroscience
Combining modern tools of neuroscience with psychological tools to analyse behaviour
Ever wondered how the brain processes the flood of input constantly streaming in from the environment?
What about how perception is translated into action? And how does our brain produce memories, emotions and conscious experiences?
Our research combines the modern tools of neuroscience (brain imaging, brain stimulation, and recording of brain electrical and haemodynamic activity) with subtle psychological tools to analyse behaviour. We’re interested in healthy functioning as well as the impact of neuropathology on cognition, perception, emotion and action.
Research laboratories
Biological psychology and cognitive neuroscience researchers work across the following laboratories:
- Attention and Human Behaviour Laboratory
-
Our research is at the interface between key human cognitive abilities, such as attention and multitasking, and human behaviours across a variety of situations.
Over a century of 'basic' experimental research has taught us a lot about human cognition and perception, as well as their underlying neural mechanisms. However, we know much less about how these abilities differ across individuals and groups, or how these abilities influence everyday behaviours, like driving, or performance in specialised jobs, like the military or air-traffic control.
The goal of our work is to answer these questions by breaking through traditional divides between basic and applied research, and to focus on building a reciprocal relationship in which basic research can guide practical questions, and practical outcomes can give new insights into basic processes.

- Cognition and Emotion
-
Clinical theorists have attributed emotional disorders to cognitive idiosyncrasies, while cognitive theorists have developed models which suggest emotional states will be associated with pervasive information processing biases throughout the cognitive system.
Both clinical and cognitive models of emotional disorders predict the existence of processing biases favouring emotionally congruent information in attention, comprehension and memory.
Current research uses cognitive-experimental paradigms to test hypotheses arising from these models, and focuses on several related questions including:
- To what extent are such biases automatic?
- What is the relative involvement of state and trait variables?
- Do information processing biases mediate emotional reaction to valenced stimuli?
- Is susceptibility to mood congruent information processing biases a vulnerability factor for emotional disorders?
Research in the Cognition and Emotion Lab is currently undertaken through the Elizabeth Rutherford Memorial Centre for the Advancement of Research on Emotion (CARE).

- Memory and Cognition Laboratory
-
Research in the Memory and Cognition Laboratory investigates human memory and reasoning, using mainly behavioural experimentation and computational modelling.
The main topics of interest are:
- Memory updating: How do we maintain an accurate representation of an ever-changing world?
- Misinformation effects: How does incorrect information affect memory, reasoning and decision-making even after it has been corrected?
- Forgetting: Why do we forget some things but not others?

- Person Perception Lab
-
Our research aims to understand the perceptual, cognitive and neural mechanisms underlying person perception.
This often involves studying faces, as they provide information about the identity, age, sex, race, attractiveness and mood of other people, but also involves studying the perception of bodies and voices.
In addition to our work with typically developing children and adults, our lab investigates person perception in children and adults with atypical development, psychopathology or brain injury. This includes studies of developmental disorders affecting face processing (congenital/developmental prosopagnosia and autism); neuropsychological studies of people with brain injuries affecting face identity recognition (acquired prosopagnosia) and expression recognition (amygdala/orbitofrontal cortex lesions); and investigations into psychopathology affecting person perception (social anxiety, callous-unemotional traits).
Our research to date has addressed three main questions:
- What is the role of visual attention in face perception?
- Why can't some children and adults recognise facial identity?
- How do we discriminate facial expressions?

Prosopagnosia Research
Interested in participating in research?
Our current understanding of prosopagnosia is only limited, and further research is needed to clarify the nature of this rare condition.

- Sensory Neuroscience Attention and Perception (SNAP) Laboratory
-
Research interests within the SNAP Lab involves three distinct arms – visual perception, clinical research and sensory neuroscience. Current projects in each of these areas are described below. Enquiries about any SNAP Lab projects below should be directed to head of SNAP lab Dr Jason Bell.
Perception research
Research in this area considers how the human visual system processes shapes and objects for recognition. Recognition is accomplished through the coordinated activation of distinct brain regions. Projects seek to discover what information is represented at each stage of processing.
Current research interests include:
- Studying the role of hemispheric specialisation in the processing of symmetry.
- The time course of visual perception. How fast and for how long do discrete visual mechanisms process content?
- The properties of the mechanisms processing visual number.
- Serial dependencies in visual perception. How and when is past information used in the processing of the present?
Clinical research
Dr. Jason Bell is interested in studying abnormalities of perception within particular groups. Together with associate professors Elizabeth Rieger (ANU) and Dr Susan Byrne (UWA), they are undertaking research to understand the relationship between biases in perception and or attention, and eating disorder symptomology, or obesity.
Current research interests include:
- Attentional biases to high and low calorie foods or to particular body shapes.
- Biases in the perceived healthiness of foods, or in the perceived size of female bodies.
- Attentional retraining procedures to reduce or null maladaptive processing strategies in relation to the above visual cues.
Together with Associate Professor Carmela Pestell (UWA), they are conducting studies to better our understanding of the relationship between ADHD and altered time perception.
Current research interests include:
- studies retraining timing abilities
- studies examining the role of emotional regulation in ADHD symptomology and time perception
Sensory neuroscience
Understanding functional specialisation in the brain is a fundamental goal of neuroscience and psychology. The lab currently offers opportunities to study the effects of neurosynchronisation and of non-invasive cortical stimulation on perception and behaviour.
Current research projects and collaborations are utilising:
- Neuroscience techniques such as transcranial direct current stimulation, or tDCS to investigate the correlates of attention and perception.
- Neurosynchronisation techniques to understand the role of rhythmic brain activity in various aspects of attention, perception and action, with a focus on theta and alpha bands.
Collaboration
Telethon Kids Institute
Staff at UWA Psychological Science collaborate extensively with the Telethon Kids Institute in research on:
- biological and neuropsychological factors implicated in the development of disorders such as autism, ADHD, FASD and language disorders;
- early identification and intervention for these disorders;
- psychological and social outcomes for children with developmental disorders and their families, and;
- the experiences of diverse youth and how this impacts on their development.
