Areas Of Interest

Dr. Volker Thoma's research topics are on fast and automatic (versus slow and controlled) mental processes in visual attention, object recognition, face recognition, implicit memory, risk perception and decision making, human factors, and behaviour change. He is using behavioural and neuroimaging techniques (EEG, fMRI, eye-tracking, tCS).

OVERVIEW

Professor Volker Thoma's research in cognitive psychology investigates the nature of processes underlying visual attention, recognition of objects (including consumer items), and judgment and decision making.  He is using behavioural and neuroimaging techniques to investigate the role of attention in object recognition and face perception. He also investigates the role of heuristics and cognitive reflection in judgment and decision-making, its correlates with thinking styles (Prof Ulrich Ettinger, Uni Bonn), and with financial decisions, including disordered gambling (with Prof. Peter Ayton, Leeds Business School).  His research also includes the origins of the centre preference effect (with Dr Paul Rodway, Chester), as well as on risk perception. Another current project is using non-invasive brain stimulation techniques (tDCS) to investigate the judgment performance in visual recognition and decision-making (with Prof. Davide Rivolta, University of Bari, and Prof. M. Nitsche, Uni Dortmund). A further interest is in applying these findings to behaviour change interventions (including the design of digital applications).

CURRENT RESEARCH

Professor Thoma's research interests are mainly in visual cognition, attention, and judgment and decision making. 

A main line of studies concerns decision making and risk perception. One project investigates heuristics and reflective thinking in experts, such as professional traders or pension trustees. Here the results show that traders, but not bankers, show higher cognitive reflection performance, but no different risk-taking. Work with pension trustees (jointly with Professor Peter Ayton, Leeds University Business School) shows that trustees show considerable bias in decision-making. 

Another line of inquiry looks at influences on consumer choice and preference, such as spatial location of products or the familiarity of brands. Items presented centrally are preferred over other positions in certain conditions (with Dr Paul Rodway, Chester). In other research, Professor Thoma showed that the familiarity of products or objects is a major determinant of preferential choice even in the context of negative information (such as consumer star ratings).

Professor Thoma's work also used behavioural and neuroimaging techniques to investigate the role of attention in object recognition (in collaboration with Prof. John Hummel, University of Illinois; Alan Richardson-Klavehn, Magdeburg; John-Dylan Haynes & Philipp Sterzer, Humboldt University Berlin) and face perception (with Jan de Fockert, Goldsmiths). 

In particular, Volker's work found that spatially unattended objects can be processed without attention, in particular, if objects are depicted in familiar views. He also showed that the capacity for face perception is limited only by the number of other faces (not other stimuli) present in a scene. Finally, work using non-invasive brain stimulation shows that transcranial Alternating Current Stimulation (tACS) of the occipito-temporal areas can improve object and face perception (with Dr Davide Rivolta, University of Bari; and Prof. Michael Nitsche, TU Dortmund).

Professor Thoma also investigates cognitive processes in decision-making using non-invasive brain stimulation. One project showed that tDCS to the right dorsolateral pre-frontal cortex improves reflective decision-making. A related line of research shows that tDCS modulates risk-taking in gambling-like tasks.

Volker is a committee member and honorary treasurer of the British Association of Cognitive Neuroscience (BACN). He serves as the coordinator of UEL's UoA 4 (REF 2021) and committee member of the School's ethics committee. He is Review Editor for Frontiers in Psychology and Frontiers in Neuroimaging and Stimulation.

Behaviour Change and Human Factors

Human choice and preferences are susceptible to internal (thoughts, motivation) and external (instructions, environment) factors. The latter can be used in 'Choice Design', to nudge people into beneficial behaviour (e.g., eat more healthily). We are studying these factors, using research on heuristics (or mental shortcuts) and how they can be used in choice design. For example, we find that from items in an array (e.g. products on a supermarket shelf) the middle one is often preferred - but this depends on some variables, such as valence (likeability), goals, and similarity.

Decision Making

Human decision making relies on different processes that are yet not fully understood. In our lab we study heuristics (mental shortcuts) in decision-making, and whether their use is determined by instructions, attention, or neural stimulation. We use eye-tracking and brain stimulation (tDCS) to study judgment and decision-making.

Face and Non-Face Object Processing Under Perceptual Load

How does our brain pick out the visual information it needs or wants from the environment and ignore what is irrelevant? Volker Thoma's research found that when perceptual load is high (e.g., many objects in a visual scene make it difficult to find an object, like your car in a full parking lot) then irrelevant information (e.g., a shopping trolley) is easy to ignore because your attentional capacity is used up by scanning many cars. If perceptual load is low, you will find your car quickly, but it will be hard to ignore irrelevant objects. Surprisingly, this is not the case for faces - no matter how many cars in the parking lot, you will always process the face of someone there. It seems that face-capacity is category-specific - only if you look for a face among many faces will your visual system ignore another face.

Attention and Object Recognition

A long-standing project in Volker Thoma's research is the role of attention in object perception, and he found evidence that an object's recognition is mediated by a hybrid representation (view-dependent and part-based) depending on whether a seen object receives visual attention or not. Brain imaging data (with Dr Rik Henson) indicate that while view-based representation components are found in ventral and dorsal object processing streams, part-based representations (depending on attention) appear to be limited to ventral processing areas in the brain. Crucially, both behavioural and imaging data find evidence for processing of objects without attention. Recent collaborations are with Prof John Dylan Haynes (Humboldt University, Berlin) and Prof. Alan Richardson-Klavehn (University of Magdeburg).
