Although the Alternative Uses divergent thinking task has been widely used in psychometric and experimental studies of creativity, the cognitive processes underlying this task have not been examined in detail before the two studies are reported here. In Experiment 1, a verbal protocol analysis study of the Alternative Uses task was carried out with a Think aloud group (N=40) and a Silent control group (N=64). The groups did not differ in fluency or novelty of idea production indicating no verbal overshadowing. Analysis of protocols from the Think aloud group suggested that initial responses were based on a strategy of Retrieval from long-term memory of pre-known uses. Later responses tended to be based on a small number of other strategies: property-use generation, imagined Disassembly of the target object into components and scanning of Broad Use categories for possible uses of the target item. Novelty of uses was particularly associated with the Disassembly strategy. Experiment 2 (N=103) addressed the role of executive processes in generating new and previously known uses by examining individual differences in category fluency, letter fluency and divergent task performance. After completing the task, participants were asked to indicate which of their responses were new for them. It was predicted and found in regression analyses that letter fluency (an executively loading task) was related to production of 'new' uses and category fluency was related to production of 'old' uses but not vice versa.

Situation awareness (SA) is one of the essential non-technical skills for effective and safe practice in high-risk industries, such as healthcare; yet, there is limited research of its significance in anaesthetic practice. In this paper, we review this scant research that focuses on SA as patient monitoring alone and advocate for a more comprehensive view of SA in anaesthetic practice and training that extends beyond monitoring, namely, a distributed cognition approach. We identify further factors influencing anaesthetists' SA and provide a case that resulted in an anaesthetic fatality to illustrate the application of an alternative view of SA in anaesthesia. Distributed SA in anaesthetic practice provides the foundation for further research that may in turn influence the teaching and assessment of this important non-technical skill.

This study aimed to investigate the roles of executive processes of inhibition and switching and verbal and visuo-spatial working memory capacities in insight and non-insight tasks.Eighteen insight tasks, 10 non-insight tasks and measures of individual differences in working memory capacities and executive functions of switching and inhibition were administered to 120 participants. Performance on insight problems was linked positively to measures of verbal and visuo-spatial working memory storage capacity but not with executive function measures. Non-insight task performance was positively linked to the executive function of switching and to verbal and visuo-spatial working memory capacity.The results are discussed in relation to dual process theories of thinking.

Summary The 4th National Audit Project of the Royal College of Anaesthetists and the Difficult Airway Society (NAP4) analysed reports of serious events arising from airway management during anaesthesia, intensive care and the emergency department. We conducted supplementary telephone interviews with 12 anaesthetists who had reported to NAP4, aiming to identify causal factors using a method based on the Human Factors Investigation Tool (HFIT). We identified contributing human factors in all cases (median [range] 4.5 [1–10] per case). The most frequent related to: situation awareness (failures to anticipate, wrong decision) (nine cases); job factors (e.g. task difficulty; staffing, time pressure) (eight cases); and person factors (e.g. tiredness, hunger, stress) (six cases). Protective factors, such as teamwork and communication, were also revealed. The post‐report HFIT interview method identified relevant human factors and this approach merits further testing as part of the investigation of anaesthetic incidents.
