From fluid intelligence to crystallised expertise: an integrative Bayesian approach. Intelligence is correlated with learning but uncorrelated with most aspects of expertise. Why is this so? Why does the role of intelligence diminish as one becomes more expert at a task? This project examines a broad range of cognitive tasks to provide a concise mathematical description of how intelligence relates to expertise.
Using written language to probe speech recognition models. Speech recognition models fall into two principal classes, with fundamentally different processing architectures. Feedback models (e.g. TRACE, McClelland & Elman, 1986) allow lexical knowledge to exert top-down control over phonemic analysis. Feedforward models (e.g. Merge, Norris, McQueen & Cutler, 2000) assume that information flow is entirely bottom-up. Our project adopts an innovative approach to testing between these model classe ....Using written language to probe speech recognition models. Speech recognition models fall into two principal classes, with fundamentally different processing architectures. Feedback models (e.g. TRACE, McClelland & Elman, 1986) allow lexical knowledge to exert top-down control over phonemic analysis. Feedforward models (e.g. Merge, Norris, McQueen & Cutler, 2000) assume that information flow is entirely bottom-up. Our project adopts an innovative approach to testing between these model classes, by examining the influence of written-word knowledge on speech perception. To distinguish the models, contrasts must test different processing levels and examine strategy effects. TRACE favors broad effects with limited strategic influence; Merge favors lexical effects that are necessarily sensitive to strategic factorsRead moreRead less
Sexism in scientific and pseudo-scientific explanations of sex inequality: an empirical, ethical and educative approach. Neuroscientific explanations of sex inequality are scientifically premature, and lead to popular exaggerations that sustain inequality through self-fulfilling effects. This project will increase understanding of these harmful consequences, and bring about essential improvements in both the quality of scientific research, and public understanding.
Wiring the retina for human vision - a single-cell behavioural approach. This project aims to combine optical and behavioural methods to explore how colour information is channelled from individual cone photoreceptors through the living human retina, to the brain. By non-invasively stimulating either a single cell or specific arrangements of cells, the project aims to contribute fundamental knowledge about how the retina is wired to inform our exquisite sense of colour and spatial vision. This u ....Wiring the retina for human vision - a single-cell behavioural approach. This project aims to combine optical and behavioural methods to explore how colour information is channelled from individual cone photoreceptors through the living human retina, to the brain. By non-invasively stimulating either a single cell or specific arrangements of cells, the project aims to contribute fundamental knowledge about how the retina is wired to inform our exquisite sense of colour and spatial vision. This understanding has consequences across a range of disciplines, including artificial vision systems such as driverless cars, retinal disease, and the processing of information through neuronal connections in general.Read moreRead less
Competent but Less Likeable: Social Stereotypes and Strategic Choices in Negotiation. Women may be disadvantaged by the greater opportunities for negotiating employment conditions that Work Choices provides. Relative to their male peers, women receive lower starting salaries and smaller increases. This is costly for women, who leave the workforce with less financial security. The gender gap is also costly for organisations, who face increased dissatisfaction and turnover. Woman can improve the ....Competent but Less Likeable: Social Stereotypes and Strategic Choices in Negotiation. Women may be disadvantaged by the greater opportunities for negotiating employment conditions that Work Choices provides. Relative to their male peers, women receive lower starting salaries and smaller increases. This is costly for women, who leave the workforce with less financial security. The gender gap is also costly for organisations, who face increased dissatisfaction and turnover. Woman can improve their outcomes through negotiation, but the assertive tactics that improve their economic outcomes are likely to generate social reprisals in the workplace. This project will benefit employers and employees alike, by identifying strategies that assist women to improve their economic outcomes while buffering them from social reprisals.Read moreRead less
The Dynamics of Trust in Negotiation: Implications for Strategy and Outcomes. Despite the benefits of cooperation, negotiators frequently choose competitive strategies. This reduces their ability to build enduring solutions that meet both negotiators' needs. In this project, we investigate the role of trust in fostering cooperation. Although trust is a pre-requisite for cooperation, negotiation research is yet to systematically explore how trust is built, sustained and violated. We test h ....The Dynamics of Trust in Negotiation: Implications for Strategy and Outcomes. Despite the benefits of cooperation, negotiators frequently choose competitive strategies. This reduces their ability to build enduring solutions that meet both negotiators' needs. In this project, we investigate the role of trust in fostering cooperation. Although trust is a pre-requisite for cooperation, negotiation research is yet to systematically explore how trust is built, sustained and violated. We test how first impressions establish trust and how patterns of communication sustain trust. We also test how salient events punctuate negotiations and alter trust. Our goal is to identify those processes that facilitate trust and cooperation in negotiation.Read moreRead less
When Targets Seek to Disconfirm Expectations: Possible Future Interactions and Target Awareness as Moderators of the Self-Fulfilling Prophecy. The self-fulfilling prophecy has been demonstrated in a series of experimental studies in which "perceivers" are led to hold erroneous expectations about "targets" with whom they interact and subsequently come to believe that targets have confirmed their expectations (perceptual confirmation). Objective raters have demonstrated that targets often do confi ....When Targets Seek to Disconfirm Expectations: Possible Future Interactions and Target Awareness as Moderators of the Self-Fulfilling Prophecy. The self-fulfilling prophecy has been demonstrated in a series of experimental studies in which "perceivers" are led to hold erroneous expectations about "targets" with whom they interact and subsequently come to believe that targets have confirmed their expectations (perceptual confirmation). Objective raters have demonstrated that targets often do confirm expectations with their actions (behavioural confirmation). However, targets do not always succumb to perceivers' expectations. The research proposed here seeks to examine the active role that targets may take in creating confirmation or disconfirmation by adding a temporal context to interactions, making targets aware of expectations, and manipulating properties of expectations.Read moreRead less
A Relational Model of Strategic Choice in Negotiation. Poorly managed negotiations have negative consequences for both individuals and organisations. They create negative emotions, damage relationships, and may require costly and time-consuming third-party interventions. An important, yet neglected, aspect of negotiations is the underlying relationship between the parties. In this project, we examine how risks to the underlying relationship, specifically, perceived trustworthiness or its lack, ....A Relational Model of Strategic Choice in Negotiation. Poorly managed negotiations have negative consequences for both individuals and organisations. They create negative emotions, damage relationships, and may require costly and time-consuming third-party interventions. An important, yet neglected, aspect of negotiations is the underlying relationship between the parties. In this project, we examine how risks to the underlying relationship, specifically, perceived trustworthiness or its lack, affect negotiators' strategy choices. Each of the risks that we identify can be offset by selecting appropriate strategies. We develop and test a model that helps negotiators identify these risks and make strategic choices that protect their interests without damaging the relationship. Read moreRead less
Currencies of Exchange: Social Utility Functions and Strategic Decisions in Negotiation. Negotiators' strategy choices are influenced by their concern about economic and social outcomes. As negotiation relationships develop, social outcomes such as reputation become increasingly influential. However, individuals differ in their willingness to trade reputation for financial gain. We investigate two factors, negotiation context and underlying relationship, that affect the relative weights assigne ....Currencies of Exchange: Social Utility Functions and Strategic Decisions in Negotiation. Negotiators' strategy choices are influenced by their concern about economic and social outcomes. As negotiation relationships develop, social outcomes such as reputation become increasingly influential. However, individuals differ in their willingness to trade reputation for financial gain. We investigate two factors, negotiation context and underlying relationship, that affect the relative weights assigned to economic and social outcomes. We link differences in these weights to differences in negotiators' strategy choices and study how weights and behaviours change over time. This enables us to identify the elements of negotiation best practice, which allows negotiators to protect both their economic and reputational outcomes. Read moreRead less
Evidence-based improvement of statistical inference practices in psychology and other disciplines. The commonest ways that many researchers currently draw conclusions from their data have been shown to be inefficient, and often used incorrectly.
