Pupil dilation as an index of effort in cognitive control tasks: A review

Pupillometry research has experienced an enormous revival in the last two decades. Here we briefly review the surge of recent studies on task-evoked pupil dilation in the context of cognitive control tasks with the primary aim being to evaluate the feasibility of using pupil dilation as an index of effort exertion, rather than task demand or difficulty. Our review shows that across the three cognitive control domains of updating, switching, and inhibition, increases in task demands typically leads to increases in pupil dilation. Studies show a diverging pattern with respect to the relationship between pupil dilation and performance and we show how an effort account of pupil dilation can provide an explanation of these findings. We also discuss future directions to further corroborate this account in the context of recent theories on cognitive control and effort and their potential neurobiological substrates.     

Creation and Implementation of an Environmental Scan to Assess Cancer Genetics Services at Three Oncology Care Settings

An environmental scan (ES) is an efficient mixed-methods approach to collect and interpret relevant data for strategic planning and project design. To date, the ES has not been used nor evaluated in the clinical cancer genetics setting. We created and implemented an ES to inform the design of a quality improvement (QI) project to increase the rates of adherence to national guidelines for cancer genetic counseling and genetic testing at three unique oncology care settings (OCS). The ES collected qualitative and quantitative data from reviews of internal processes, past QI efforts, the literature, and each OCS. The ES used a data collection form and semi-structured interviews to aid in data collection. The ES was completed within 6 months, and sufficient data were captured to identify opportunities and threats to the QI project’s success, as well as potential barriers to, and facilitators of guideline-based cancer genetics services at each OCS. Previously unreported barriers were identified, including inefficient genetic counseling appointment scheduling processes and the inability to track referrals, genetics appointments, and genetic test results within electronic medical record systems. The ES was a valuable process for QI project planning at three OCS and may be used to evaluate genetics services in other settings.     

Motivated or Demotivated to Be Creative: The Role of Self‐Regulatory Focus in Transformational and Transactional Leadership Processes

Numerous studies have recognised the importance of transformational leadership style for encouraging employees’ creativity. Self‐regulation studies have highlighted the influence of a promotion focus on employees’ creative behaviours. Yet both leadership and self‐regulation theories have paid less attention to the role transactional leadership style and situational prevention regulatory focus may play in affecting employees’ creativity. In this article we present a theoretical model which examines transformational and transactional leadership styles and both promotion and prevention situational self‐regulatory focus (SRF). The model suggests that while transformational leadership promotes creativity, at least partially by enhancing follower's situational promotion SRF, transactional leadership style (transactional active) is aligned with followers’ prevention situational SRF, which is associated with leaders’ hindering of followers’ creativity. Findings from two studies, an experimental study (N = 189) and a field study (N = 343 employees and 75 managers), support this model, showing that the relationship between different types of leadership and creativity are more complex than previously regarded. The theoretical and practical implications are discussed.     

The dimensions of deception detection: Self‐reported deception cue use is underpinned by two broad factors

Many perceived cues to deception have been reported in the literature, but little attention has been paid to how they are combined when making deception judgments. The present research used a data‐driven approach to investigate how cues are integrated when evaluating veracity. Two hundred fifteen participants performed a deception detection task before completing a deception cue use questionnaire. A factor analysis of the questionnaire data produced two dimensions, one associated with nonverbal cues to anxiety and the other associated with detail and level of involvement. The present work extends our understanding of deception detection processes and underlines the importance of examining not only the cues that people use but also the way in which they use them.     

Behavioural Consistency Within the Prisoner's Dilemma Game: The Role of Personality and Situation

Mixed‐motive games represent situations that confront people with a conflict between cooperative and non‐cooperative alternatives. Despite this common basis, recent research has shown that the consistency of people's choices across different mixed‐motive games is rather low. The present research examined behavioural consistency within the same mixed‐motive game, by presenting participants with a series of one‐shot Prisoner's Dilemma Games. Across this set of games, payoffs were manipulated in order to intensify or weaken the conflict between self and the other party while maintaining the game's underlying structure. Our findings indicate that significant differences in choice behaviour are observed as a function of both situational (i.e. manipulations of the Prisoner's Dilemma Game's payoff structure) and personality differences (i.e. individual differences in personality and motivational traits). Moreover, our included situational variables and personality features did not interact with each other and were about equally impactful in shaping cooperation. Crucially, however, despite the significant behavioural differences across game variants, considerable consistency in choices was found as well, which suggests that the game's motivational basis reliably impacts choice behaviour in spite of situational and personality variations. We discuss implications for theorizing on mixed‐motive situations and elaborate on the question how cooperation can be promoted. © 2018 European Association of Personality Psychology     

AINSWORTH'S STRANGE SITUATION PROCEDURE: THE ORIGIN OF AN INSTRUMENT

The American‐Canadian psychologist Mary Ainsworth (1913–1999) developed the Strange Situation Procedure (SSP) to measure mother‐child attachment and attachment theorists have used it ever since. When Ainsworth published the first results of the SSP in 1969, it seemed a completely novel and unique instrument. However, in this paper we will show that the SSP had many precursors and that the road to such an instrument was long and winding. Our analysis of hitherto little‐known studies on children in strange situations allowed us to compare these earlier attempts with the SSP. We argue that it was the combination of Ainsworth's working experience with William Blatz and John Bowlby, her own research in Uganda and Baltimore, and the strong connection of the SSP with attachment theory, that made the SSP differ enough from the other strange situation studies to become one of the most widely used instruments in developmental psychology today.
