Behavioural Science Explained

We explain the famous Fogg Behaviour Model (FBM), a framework for understanding and influencing behaviour change. Several sources detail the model's core components—motivation, ability, and prompts—and their interplay in achieving desired actions. Applications across diverse fields are examined, including marketing, website design, and public health interventions, with case studies illustrating successful implementation and challenges encountered. A key focus is on optimising for ease of action ("ability") alongside motivational strategies, rather than relying solely on high motivation.

We detail out motivational interviewing (MI), a technique for boosting motivation to change behaviour. Several sources explore MI's core principles, including collaborative partnerships, empathy, and respecting client autonomy. Specific MI skills are examined, such as reflective listening, open-ended questioning, and responding to ambivalence and resistance. Practical applications are illustrated through case studies and exercises, demonstrating how MI is used across various settings and populations, including substance abuse treatment, stress management, and healthcare. Finally, the texts also discuss training and supervision in MI, highlighting their importance for skill development and maintenance.

We discuss Cognitive Load Theory (CLT), a learning theory focusing on the limitations of working memory. Sweller's work establishes CLT's foundation, explaining its principles based on evolutionary psychology and cognitive architecture. Sithole applies CLT to accounting education, offering practical guidelines for instruction design. Sawicka proposes a model-based approach to studying CLT's complex dynamics through mathematical simulation. Finally, Ayres and van Gog review current CLT research, highlighting advancements and future directions, particularly concerning germane load and the measurement of cognitive processes.

We explore behaviour change through various lenses. One study analyses how macroeconomic and microeconomic conditions differentially affect household grocery shopping behaviour, revealing nuanced responses to income changes and economic cycles. Another examines the relationship between attitude and behaviour change, proposing that the sequence depends on the level of uncertainty surrounding outcomes versus consequences. A third source details behavioural modification techniques, focusing on reinforcement and its application in psychology and education. Finally, a fourth study investigates gamification's impact on sustainable consumer behaviour, modelling the influence of reward-based game design elements on knowledge, attitudes, intentions, and ultimately, energy-saving actions.

We examine action bias, a cognitive bias favouring action over inaction, across diverse contexts. One study analyses this bias in elite soccer goalkeepers, demonstrating their preference for jumping (action) during penalty kicks, even when statistically, staying in the centre (inaction) would be more effective. Another explores action bias within the water industry, highlighting how the urge to act can lead to suboptimal solutions like partial lead pipe replacements. A third study investigates the interplay of goal-based action selection and utility-based action bias in the brain, proposing distinct neural mechanisms and their interaction in adapting to new environments. Finally, a case study illustrates how an affirmative action plan, despite good intentions, can mask managerial bias in hiring and promotion decisions if poorly implemented and coupled with flawed selection processes.

Through some research papers we explore individual variations in incentive salience attribution, focusing on how cues associated with rewards, particularly drugs and social interactions, influence behaviour. Studies using Pavlovian conditioning in rats reveal distinct behavioural phenotypes: sign-trackers, who attribute high motivational value to cues, and goal-trackers, who focus on the reward itself. The studies investigate the neural mechanisms underlying these differences, exploring the roles of dopamine and other neurochemicals like oxytocin, and consider the implications for understanding and treating addiction. The research also examines how reward uncertainty and multiple reward types affect incentive salience attribution, further enriching our understanding of reward processing and addiction vulnerability.

We discuss social identity theory and its applications in understanding intergroup conflict and peacebuilding. They examine how social categorisation, group membership, and identity management strategies influence intergroup relations, focusing on various contexts including religious communities, political movements, and national identities. We analyse how power relations, ideology, and historical factors shape identity formation and its impact on conflict and cooperation. Furthermore, the sources discuss the potential of social identity theory to inform interventions promoting peace and social change, particularly in diverse and complex societies. Several case studies illustrate the practical implications of the theory.

We explore optimism bias, a cognitive bias where individuals overestimate the likelihood of positive events and underestimate negative ones. Several studies examine this bias in different contexts: financial decision-making in insurance markets, prediction of future adverse life events influenced by dopamine levels, cost overruns in large-scale bridge projects, risk perception during the COVID-19 pandemic, and forecasting success in American Football. Researchers analyse the bias's prevalence, influencing factors (age, health, etc.), and potential interventions to mitigate its negative consequences, such as improved risk assessment and safer driving practices.

We explore William T. Powers's control theory, arguing that behaviour is fundamentally about controlling one's perception of the self and environment, rather than simply reacting to stimuli. The theory is presented as a negative feedback loop model, applicable across various domains. Empirical evidence supporting this model, primarily from manual tracking tasks, is discussed alongside its application in interventions across child development, education, mental health, and organisational psychology. The limitations of traditional stimulus-response models and the potential of control theory for more effective interventions are highlighted.

The sources discuss how physiological and psychological factors involved with sex and sexual arousal's impact decision-making.

One study investigated how working memory capacity (WMC) moderates the relationship between physiological arousal and sexual decision-making in men. The study found that men with lower WMC who were more aroused by non-consensual sexual images, indicated a higher likelihood of engaging in sexually aggressive behaviour. Those with higher WMC were not as impacted by the physiological arousal. This suggests that executive functioning plays a role in moderating decisions regarding sexually aggressive behaviour.

Another study examined the impact of sexual arousal on self-control and sexual self-restraint. Researchers found that heightened sexual arousal is associated with a decrease in self-control and sexual self-restraint. This is possibly due to the depletion of self-control resources when experiencing arousal. The study suggests that individuals in a state of arousal may prioritise short term gratification over long term consequences.

A third study looked at the effects of sexual arousal on the attractiveness of different activities, willingness to engage in morally questionable behaviours, and willingness to engage in unsafe sex. The results showed that sexual arousal amplified the attractiveness of various sexual activities, increased the likelihood of engaging in morally dubious behaviours to procure sex, and decreased the possibility of using condoms, suggesting a shift in perception of trade-offs between benefits and disadvantages. The study also suggests that people have limited insight into the effects of sexual arousal on their decisions.
