Purpose
Identifying the characteristics of chief executive officers (CEOs) has been a longstanding goal in leadership and individual differences research. The purpose of this exploratory study was to consider which individual difference and career path variables differentiate CEOs from other senior managers.Design/Methodology/Approach
Participants (N = 1152) were UK-based senior managers (n = 1040) and CEOs (n = 112) who completed a self-report measure of the Five Factor Model of personality (NEO-PI-R), a measure of cognitive ability (graduate and management aptitude test), and answered a number of additional questions on their career paths as part of development centres. Analyses comprised inter-individual mean difference tests, intra-individual external profile analysis and logistic regression.Findings
Results indicated that personality facets of impulsiveness, vulnerability, activity and dutifulness showed the largest mean differences. No significant effects were found for the criterion profile pattern, but significant effects were found for profile level. Of the additional predictors, career path variables were the strongest predictors of CEO status.Implications
The combination of significant effects across domains of individual differences and career path variables emphasizes the importance of a multivariate approach in the study of leadership, top management teams and career progression.Originality/Value
The current study combines personality, cognitive ability, demographic and career path variables, and applies intra-individual methodologies to explore the characteristics of the very top level of organisational hierarchy.122.
New Caledonian crows are the most proficient non-hominin tool manufacturers but the cognition behind their remarkable skills
remains largely unknown. Here we investigate if they attend to the functional properties of the tools that they routinely
use in the wild. Pandanus tools have natural barbs along one edge that enable them to function as hooking implements when
the barbs face backwards from the working tip. In experiment 1 we presented eight crows with either a non-functional (‘upside-down’)
or a functional pandanus tool in a baited hole. Four of the crows never flipped the tools. The behaviour of the four flipping
birds suggested that they had a strategy of flipping a tool when it was not working. Observations of two of the eight crows
picking up pandanus tools at feeding tables in the wild supported the lack of attention to barb direction. In experiment 2
we gave six of the eight crows a choice of either a barbed or a barbless pandanus tool. Five of the crows chose tools at random,
which further supported the findings in experiment 1 that the crows paid little or no attention to the barbs. In contrast,
a third experiment found that seven out of eight crows flipped non-functional stick tools significantly more than functional
ones. Our findings indicate that the crows do not consistently attend to the presence or orientation of barbs on pandanus
tools. Successful pandanus tool use in the wild seems to rely on behavioural strategies formed through associative learning,
including procedural knowledge about the sequence of operations required to make a successful pandanus tool.

This study examined the effects of age on single- and dual-task listening and walking during virtual street crossing. Seventeen younger and 12 older adults participated. In each listening trial, three sentences were presented simultaneously from separate locations. Participants were instructed to report the target sentence. Predictability of the target sentence location was varied. Treadmill walking was measured using motion analysis. Measures included word recognition accuracy, head and trunk angles, and spatiotemporal gait parameters. Older adults exhibited a more upright head alignment and less variability in stride time during dual-tasking, particularly under less certain target sentence location conditions. Younger adults’ walking was unaffected by dual-task demands. Together, the results indicate greater postural prioritization in older adults than young. 相似文献

This paper examines the methodological claim made famous by P. F. Strawson: that we understand what features are required for responsible agency by exploring our attitudes and practices of holding responsible. What is the presumed metaphysical connection between holding responsible and being fit to be held responsible that makes this claim credible? I propose a non‐standard answer to this question, arguing for a view of responsible agency that is neither antirealist nor straightforwardly realist. It is instead “constructivist.” On the “Scaffolding View” I defend, reactive attitudes play an essential role in developing, supporting, and thereby maintaining the capacities that make for responsible agency. Although this view has relatively novel implications for a metaphysical understanding of capacities, its chief virtue, in contrast with more standard views, is in providing a plausible defense of why so‐called “responsible agents” genuinely deserve to be treated as such. 相似文献

Previous studies have hinted at sex differences in developmental trajectories in ADHD symptoms; however, little is known about the nature or cause of these differences and their implications for clinical practice. We used growth mixture modelling in a community‐ascertained cohort of n = 1,571 participants to study sex differences in ADHD symptom developmental trajectories across the elementary and secondary school years. Participants were measured at ages 7, 8, 9, 10, 11, 12, 13, and 15. We found that females were more likely to show large symptom increases in early adolescence while males were more likely to show elevated symptoms from childhood. For both males and females, early adolescence represented a period of vulnerability characterized by relatively sudden symptom increases. Females affected by hyperactivity/impulsivity may be more likely to be excluded from diagnosis due to current age of onset criteria. More attention should be paid to early adolescence as a period of risk for hyperactivity/impulsivity symptom onset or worsening. 相似文献

Mothers in low‐ and middle‐income countries (LMIC) suffer heightened vulnerability for adverse childhood experiences (ACEs), which is exacerbated by the multitude of risk factors associated with poverty and may lead to increased risk of psychiatric disorder. The constellation of complex, co‐occurring biological, environmental, social, economic and psychological risk factors are in turn transmitted to her child, conferring vulnerability for adverse development. This study examines the association between maternal intra‐ and extra‐familial ACEs, maternal education and the mental health of her child, mediated by maternal mental health. Mother‐child dyads (n = 121) in Machakos, Kenya were examined cross‐sectionally using self‐report measures of ACEs, maternal mental health and child internalizing and externalizing mental health problems. The four models proposed to examine the relationship between intra‐ and extra‐familial maternal ACEs and child internalizing and externalizing problems demonstrated indirect pathways through maternal mental health. These effects were found to be conditional on levels of maternal education, which served as a protective factor at lower levels of maternal ACEs. These models demonstrate how the impact of ACEs persists across the lifespan resulting in a negative impact on maternal mental health and conferring further risk to subsequent generations. Elucidating the association between ACEs and subsequent intergenerational sequelae, especially in LMIC where risk is heightened, may improve targeted caregiver mental health programs for prevention and intervention. 相似文献

ABSTRACTDo women with body hair continue to evoke disgust? Are men without body hair read only as athletes and/or gay? To explore contemporary sense-making practices around apparently counter-normative gendered body hair practice, we developed a two-stem story completion task. We collected stories from 161 undergraduate students (129 women and 32 men) about David, who had decided to start removing body hair, and Jane, who had decided to stop removing body hair. We analysed the data thematically within a constructionist framework, resulting in three themes: secrecy and shame; the personal benefits of going against the grain; and the personal is political. The personal benefits theme included four distinct (gendered) subthemes: increased heterosexual attractiveness; increased sporting prowess; removal of a hassle; and liberation from conformity. These story data gave access to familiar but also somewhat different accounts than those collected through typical self-report measures. 相似文献

Involuntary musical imagery (INMI), i.e the internal experience of a repetitive musical fragment, is one of the most ubiquitous forms of spontaneous cognition. Findings regarding the relationship between INMI and cognitive load are conflicting. In the present study, 200 participants watched and evaluated two non-dialogue, music-only film trailers. Subsequently, they either closed their eyes for 5 min (baseline), or engaged in one of three dot tasks of varying challenge and attentional demand (low, medium, and high cognitive load). Finally, they completed a novel “Mind Activity Questionnaire”, which allows for indirect INMI sampling rather than direct questioning. The same questionnaire was completed 24 hours later. Overall, a significant negative linear trend was found. At baseline, 65% of people reported experiencing INMI. This rate decreased to 32.5% in the low load condition with further reductions observed in the medium and high conditions, which did not differ significantly from each other. INMI frequency and duration followed the same pattern as the induction rates. In the 24-hour follow-up, 21% of participants reported INMI experiences. This study supports the hypothesis that INMI occurrence, frequency, and duration relate to spare cognitive capacity and demonstrates an ecologically valid laboratory paradigm for covertly inducing and documenting INMI experiences. 相似文献
