Impact of automation on aircrew communication and decision-making performance

Increasing levels of automation are being introduced into the cockpit. Yet, it is difficult to predict the impact of these automatic systems on other elements of flight, such as crew communication and the ability to arrive at an effective decision. This study attempted to clarify the relation among these variables. Forty-eight pilots were assigned to two-person crews and asked to fly a simulated mission in either automated or manual conditions using a low-fidelity simulator. The scenario was designed to require crewmembers to arrive at a collective decision based on information obtained about an evolving simulated disaster. The results indicated that the introduction of automation was not associated with better performance. However, several significant differences were observed in the communications of crews flying in the automated versus manual conditions. The results are discussed in terms of their implications for communications training for advanced technology aircraft.     

Automation bias: decision making and performance in high-tech cockpits

Automated aids and decision support tools are rapidly becoming indispensable tools in high-technology cockpits and are assuming increasing control of"cognitive" flight tasks, such as calculating fuel-efficient routes, navigating, or detecting and diagnosing system malfunctions and abnormalities. This study was designed to investigate automation bias, a recently documented factor in the use of automated aids and decision support systems. The term refers to omission and commission errors resulting from the use of automated cues as a heuristic replacement for vigilant information seeking and processing. Glass-cockpit pilots flew flight scenarios involving automation events or opportunities for automation-related omission and commission errors. Although experimentally manipulated accountability demands did not significantly impact performance, post hoc analyses revealed that those pilots who reported an internalized perception of "accountability" for their performance and strategies of interaction with the automation were significantly more likely to double-check automated functioning against other cues and less likely to commit errors than those who did not share this perception. Pilots were also lilkely to erroneously "remember" the presence of expected cues when describing their decision-making processes.     

Simultaneous administration of the Rosenberg Self-Esteem Scale in 53 nations: exploring the universal and culture-specific features of global self-esteem

The Rosenberg Self-Esteem Scale (RSES) was translated into 28 languages and administered to 16,998 participants across 53 nations. The RSES factor structure was largely invariant across nations. RSES scores correlated with neuroticism, extraversion, and romantic attachment styles within nearly all nations, providing additional support for cross-cultural equivalence of the RSES. All nations scored above the theoretical midpoint of the RSES, indicating generally positive self-evaluation may be culturally universal. Individual differences in self-esteem were variable across cultures, with a neutral response bias prevalent in more collectivist cultures. Self-competence and self-liking subscales of the RSES varied with cultural individualism. Although positively and negatively worded items of the RSES were correlated within cultures and were uniformly related to external personality variables, differences between aggregates of positive and negative items were smaller in developed nations. Because negatively worded items were interpreted differently across nations, direct cross-cultural comparisons using the RSES may have limited value.     

The role of positive and negative emotions in life satisfaction judgment across nations

This study examined how the frequency of positive and negative emotions is related to life satisfaction across nations. Participants were 8,557 people from 46 countries who reported on their life satisfaction and frequency of positive and negative emotions. Multilevel analyses showed that across nations, the experience of positive emotions was more strongly related to life satisfaction than the absence of negative emotions. Yet, the cultural dimensions of individualism and survival/self-expression moderated these relationships. Negative emotional experiences were more negatively related to life satisfaction in individualistic than in collectivistic nations, and positive emotional experiences had a larger positive relationship with life satisfaction in nations that stress self-expression than in nations that value survival. These findings show how emotional aspects of the good life vary with national culture and how this depends on the values that characterize one's society. Although to some degree, positive and negative emotions might be universally viewed as desirable and undesirable, respectively, there appear to be clear cultural differences in how relevant such emotional experiences are to quality of life.     

COMPARISONS OF SOCIO-POLITICAL ATTITUDES BETWEEN TWO DEMOCRATIC SOCIETIES

Three-hundred and twenty-seven Australian and 192 Swedish psychology students were compared with respect to four aspects of socio-politico attitudes: (a) differences in average levels for items and dimensions, (b) differences in degrees of consensus for specific issues (items), (c) differences in the structures of socio-politico attitudes and (d) differences in the profiles of attitudes across relevant items and dimensions. Analyses of variance showed that, in general, Swedes were significantly less conservative than Australians. The largest difference between the two samples were found for the dimension of punitiveness where Swedes were found to be much less punitive than Australians. The results also disclosed that there was greater ideological consensus and consistency among Swedes than among Australians. In line with earlier cross-cultural research, the results also disclosed a relatively high level of ideological profile and structural similarity among the two western nations.     

Differential Sensitivity of Using Simulators Versus Actual Aircraft to Evaluate the Effects of a Stimulant Medication on Aviator Performance

The comparability of simulator versus aircraft results was examined with a quasi-experimental approach. Flight data from 10 UH-60 pilots, who flew a helicopter simulator, and 10 pilots who flew an aircraft were pooled to assess the influence of the flight platform on Dexedrine® versus placebo effects in two 40-hr periods of sustained wakefulness. Overall, performance under Dexedrine® was better than performance under placebo, but consistent stimulant and fatigue effects were observed across both flight platforms less than one third of the time. Sensitivity was lower in the aircraft, likely because of differences due to environmental influences (weather, temperature, and turbulence) and other factors (radio traffic and, possibly, anxieties about safety). Thus, simulator studies, although desirable in terms of cost and safety, may overestimate the impact of stressors (e.g., fatigue) as well as the potential benefits from fatigue countermeasures (e.g., Dexedrine®). Conversely, in-flight studies may underestimate these types of performance effects. As a result, caution is advised when attempting to generalize findings from one flight platform to the other.     

Assessing the influence of operational factors on the perceived structure of real-world scenes viewed during low-altitude, high-speed flight

Previous research indicates that pilots of most jet-fighter aircraft attend to similar elements of the natural flight environment when flying at low altitudes. However, some evidence suggests that differences may exist for pilots of certain specific types of aircraft. The present experiment examined the influence of operational factors on the perceived structure of real-world scenes viewed during low-altitude flight. Multidimensional scaling analyses with stimuli consisting of videotape segments of low-altitude flight over a variety of real-world terrains revealed differences in perceived environmental structure for pilots assigned to different types of jet-fighter aircraft. These results provide evidence that perceptual learning evolves differently under different operational conditions and suggests that training programs should be designed to reflect those differences.     

Decomposing self‐estimates of intelligence: Structure and sex differences across 12 nations

This study examines the structure of self‐estimates of intelligence (SEI) across 12 nations (Australia, Austria, Brazil, France, Iran, Israel, Malaysia, South Africa, Spain, Turkey, UK and US). Participants rated themselves on general and specific abilities from three popular models of intelligence: Gardner's multiple intelligences, Sternberg's triarchic theory of intelligence, and Goleman's emotional intelligence. The results showed that (a) laypeople across nations have similar and invariant concepts of intelligence, (b) concepts of intelligence are cross‐culturally closely related to academic notions of intellectual ability and (c) sex differences in general and specific SEI favouring men are consistent across countries. Male hubris and female humility in SEI seem independent of sex differences in actual cognitive ability and national levels of masculinity‐femininity. Furthermore, international mean differences in general SEI could not be attributed to discrepancies in national intelligence quotient (IQ) levels or to cultural variations.     

Analysis of NTSB Aircraft‐Assisted Pilot Suicides: 1982–2014

On March 24, 2015, a Germanwings aircraft crashed in the Alps. The suicidal copilot killed himself and 150 others. Pilot suicide is rare, but does happen. This research analyzed the National Transportation Safety Board's accident database (eADMS) looking for pilots who died by suicide in flight. Fifty‐one suicides were identified. Gender, age, and other characteristics were examined. Average age of suicidal pilots was 38, significantly different from the average age of 45 for all male pilots involved in aircraft accidents. A discriminant function accurately identified suicidal incidents at 96%. There was a high false‐positive rate limiting the usefulness of the discriminant function.     

Why can't a man be more like a woman? Sex differences in Big Five personality traits across 55 cultures

Previous research suggested that sex differences in personality traits are larger in prosperous, healthy, and egalitarian cultures in which women have more opportunities equal with those of men. In this article, the authors report cross-cultural findings in which this unintuitive result was replicated across samples from 55 nations (N = 17,637). On responses to the Big Five Inventory, women reported higher levels of neuroticism, extraversion, agreeableness, and conscientiousness than did men across most nations. These findings converge with previous studies in which different Big Five measures and more limited samples of nations were used. Overall, higher levels of human development--including long and healthy life, equal access to knowledge and education, and economic wealth--were the main nation-level predictors of larger sex differences in personality. Changes in men's personality traits appeared to be the primary cause of sex difference variation across cultures. It is proposed that heightened levels of sexual dimorphism result from personality traits of men and women being less constrained and more able to naturally diverge in developed nations. In less fortunate social and economic conditions, innate personality differences between men and women may be attenuated.     

Expanding the g-nexus: Further evidence regarding the relations among national IQ, religiosity and national health outcomes

The current study seeks to better understand how religiosity and health are positioned within the g-nexus. Specifically, the degree to which differences in average IQ across nations is associated with differences in national religiosity (i.e., belief rate) and national health statistics independent of differences in national wealth is examined. Consistent with expectations, results show that, independent of national wealth and belief rate, IQ has a positive influence on national health as indicated by fertility rate, infant mortality rate, maternal mortality rate, and deaths due to HIV/AIDS, and life expectancy. Additionally, as hypothesized, IQ and belief rate interacted to influence reproductive health (i.e., fertility rate, infant- and maternal mortality). Specifically, high IQ acts as a buffer against the negative effects of belief rate; when IQ is high belief rate has no effect, but when IQ is low belief rate has a strong negative effect. The pattern of findings from this study, combined with previous research, serve to confirm that general cognitive ability (i.e., the g-factor) is an important and central node within a larger nexus of psychological and social variables. Theoretical and epidemiological implications are discussed.     

School-level genetic variation predicts school-level verbal IQ scores: Results from a sample of American middle and high schools

Research has consistently revealed that average IQ scores vary significantly across macro-level units, such as states and nations. The reason for this variation in IQ, however, has remained at the center of much controversy. One of the more provocative explanations is that IQ across macro-level units is the result of genetic differences, but empirical studies have yet to examine this possibility directly. The current study partially addresses this gap in the literature by examining whether average IQ scores across thirty-six schools are associated with differences in the allelic distributions of dopaminergic polymorphisms across schools. Analysis of data drawn from subjects (ages 12-19 years) participating in the National Longitudinal Study of Adolescent Health provides support in favor of this perspective, where variation in school-level IQ scores was predicted by school-level genetic variation. This association remained statistically significant even after controlling for the effects of race.     

飞行中惊吓和惊奇的管理——拓展的Landman模型

在飞行活动中,飞行员的惊吓和惊奇反应是导致飞行失控的重要因素。惊吓和惊奇反应可能使飞行员熟练训练过的操作程序和技能被遗忘,取而代之的是不适当的直觉性的行为或草率的决策。现有的使用飞行模拟器的研究表明,Landman模型对减轻飞行员惊吓和惊奇的训练有重要价值。在Landman模型的基础上,我们加入了飞行员心理能力的个体间差别（即拓展的Landman模型）,因此拓展的Landman模型对于飞行员的选拔和训练将具有重要意义。     

Illusory displacement of a moving trace with respect to the grid during oscilloscope motion

Observers report that a trace streak, which follows a sinusoidal path, moves vertically with respect to the oscilloscope’s grid when an oscilloscope is oscillated in the vertical plane. The vertical component of the trace streak motion with respect to the grid is illusory. This illusion is stable across a limited range of illumination and physical motion conditions. We hypothesize that this illusion is based on the manner in which the visual system calculates the vertical location of the grid and the trace: the trace location is determined on a moment-to-moment basis, whereas the grid tends to be seen in its average vertical position. The results of two experiments indicate that this hypothesis can account, at least partially, for the illusion. The illusion may have practical implications for pilots or navigators who track target blips on radar screens in moving aircraft.     

Greater Happiness for a Greater Number: Some Non-controversial Options for Governments

There are dramatic differences in average happiness across nations ranging from 3.24 in Togo to 8.00 in Denmark on a 0–10-points scale. These differences are an indication that collective conditions in nations are important for happiness. Can governments play a role in the creation of such conditions? This question is addressed in an analysis of average happiness in 131 nations in 2006. The following sub-questions are considered. (1) Is there a positive correlation between average happiness in nations and the quality or the size of governments? (2) Can we explain a positive correlation in terms of causality? (3) Can we specify causality by discerning direct and indirect effects? (4) What about governments and inequality in happiness? (5) What can governments do to increase happiness intentionally? The conclusion is that the technical quality of governments is an important cause for average happiness in nations, and this causality can be specified to some extent. Good governments also reduce inequality of happiness in nations eventually. The implication is that governments can increase average happiness, and in due time reduce inequality in happiness, and that they have some non-controversial options to do so on purpose.     

An evaluation of the cross‐national generalizability of organizational commitment

Using data from two large multinational samples, this research sought to contribute to our knowledge of international organizational behaviour by examining the cross‐national generalizability of organizational commitment. Sample 1 included employees of 10 subsidiaries of a large multinational organization, whereas Sample 2 relied on data collected in 25 nations in the context of a large opinion survey. Results in both samples supported the expectation that measures of commitment would be more susceptible to measurement non‐equivalence than measures of job satisfaction. Differences in relationships between commitment and satisfaction across countries were observed in both samples, as were differences in mean commitment levels. Nation‐level individualism/collectivism (I/C) failed to account for the observed differences, however, suggesting that commitment and I/C are largely independent, despite theoretical arguments to the contrary. Results of the study suggest that despite some cross‐national variation, differences in commitment across national boundaries are small and empirically unrelated to I/C.     

Broverman's methodology reversed: assessing university students' perceptions of the gender-role characteristics of counselors

This study examined university students' perceptions of which gender-role characteristics described helpful counselors for 137 nonmajors from an introduction to counseling class. Using a modification of the Broverman, et al. method (1970) and a modified version of their Stereotype Questionnaire, participants were randomly assigned to one of three conditions. Participants indicated the characteristics of a helpful counselor, a helpful female counselor, or a helpful male counselor using 20 bipolar items of gender-role characteristics. t tests were applied to whether agreement of the pole considered most frequently was greater than chance (50%). Analysis indicated agreement on characteristics were most helpful in a counselor, and the direction of this agreement did not differ across the three conditions or as a function of participants' sex. Agreement was high for the individual gender-role characteristic items across conditions as two of 20 items showed significant differences. There was significantly more agreement that male counselors should not have their feelings easily hurt than female counselors and significantly less agreement that male counselors should be able to express tender feelings easily relative to a counselor of unspecified sex.     

Recursive Partitioning to Identify Potential Causes of Differential Item Functioning in Cross-National Data

Differential item functioning (DIF) assessment is key in score validation. When DIF is present scores may not accurately reflect the construct of interest for some groups of examinees, leading to incorrect conclusions from the scores. Given rising immigration, and the increased reliance of educational policymakers on cross-national assessments such as Programme for International Student Assessment, Trends in International Mathematics and Science Study, and Progress in International Reading Literacy Study (PIRLS), DIF with regard to native language is of particular interest in this context. However, given differences in language and cultures, assuming similar cross-national DIF may lead to mistaken assumptions about the impact of immigration status, and native language on test performance. The purpose of this study was to use model-based recursive partitioning (MBRP) to investigate uniform DIF in PIRLS items across European nations. Results demonstrated that DIF based on mother's language was present for several items on a PIRLS assessment, but that the patterns of DIF were not the same across all nations.     

Culture, gender, and the self: variations and impact of social comparison processes

Psychological differences between women and men, far from being invariant as a biological explanation would suggest, fluctuate in magnitude across cultures. Moreover, contrary to the implications of some theoretical perspectives, gender differences in personality, values, and emotions are not smaller, but larger, in American and European cultures, in which greater progress has been made toward gender equality. This research on gender differences in self-construals involving 950 participants from 5 nations/cultures (France, Belgium, the Netherlands, the United States, and Malaysia) illustrates how variations in social comparison processes across cultures can explain why gender differences are stronger in Western cultures. Gender differences in the self are a product of self-stereotyping, which occurs when between-gender social comparisons are made. These social comparisons are more likely, and exert a greater impact, in Western nations. Both correlational and experimental evidence supports this explanation.
