Explicit or implicit situation awareness? Measuring the situation awareness of train traffic controllers

Previous research on situation awareness (SA) predominantly focused on its explicit, reasoned, conscious features rather than on the implicit, intuitive, unconscious aspects that are often identified with expert operators. This research investigated implicit levels of SA of train traffic controllers (TTCs) in order to contribute to the body of knowledge on rail human factors research and SA. A novel approach was used to uncover levels of implicit SA through a set of three analyses: (1) fairly low SAGAT values with correlations between SAGAT scores and multiple performance indicators; (2) negative correlations between work experience and SAGAT scores; and (3) structurally lower level-1 SA (perception) scores in comparison to level-2 SA (comprehension) scores in accordance with Endsley’s three-level model. Two studies were conducted: A pilot study – which focused on SA measurements with TTCs in a monitoring mode (N = 9) – and the main study, which involved TTCs from another control center (N = 20) and three different disrupted conditions. In the pilot study, SA was measured through the situation-awareness global assessment technique (SAGAT), perceived SA and observed SA, and performance was measured through punctuality and unplanned stops of trains before red signals. In the main study, SA was measured through SAGAT, and perceived SA and multiple performance indicators, such as arrival and departure punctuality and platform consistency, were assessed. In both studies, the set of three analyses showed consistent and persistent indications of the presence of implicit SA. Endsley’s three-level model and related SAGAT method can be constrained by the presence of these intuitive, unconscious processes and inconsistent findings on correlations between SAGAT scores and performance. These findings provide insights into the SA of TTCs in the Netherlands and can support the development of training programs and/or the design of a new traffic management system.     

The Effects of Uncontrollable, Unpredictable Aversive and Appetitive Events: Similar Effects Warrant Similar, but not Identical, Explanations?

Exposure to uncontrollable, unpredictable appetitive events produces a variety of cognitive debilitations and vegetative changes, as does exposure to uncontrollable, unpredictable aversive events. Similarities include impaired escape from aversive events, impaired discrimination, finicky consumption, analgesia, and body weight loss. However, in stark contrast, uncontrollable aversive stress causes reduced motor activity where as similar appetitive treatment does not; aversively induced debilitation is causally related to energy regulation, whereas the appetitively induced effects are not. Parallel mechanisms are suggested to explain these effects in terms of a revised anxiety account of the aversive effects, and a frustration account of the appetitive effects. Finally, factors likely to limit important research to resolve the many remaining issues are identified: negative presentation of animal research, political decision making, and ignorance and fear in committees which review the ethics of research.     

In a no-win situation: The employment–health dilemma

Work and organizational psychology (WOP) research has to date mostly focused on people privileged to have the choice between several attractive job options and less on people who are restricted in their job choice (e.g., due to their qualification or personal contingencies) and have to choose from fewer and often less-than-optimal jobs. Often, the jobs available to the latter are characterized by precarious employment and hazardous working conditions which can put them in the difficult situation of having to choose between a health-threatening job and possible unemployment. Building on interdisciplinary literature, we propose the employment–health dilemma (E-H dilemma) as a framework for analyzing this intrapersonal conflict of having to choose between employment (incurring health threats) and health (incurring economic threats) and discuss potential antecedents and consequences of the E-H dilemma at the societal, organizational, and individual level. We outline the implications of the E-H dilemma and make a case for examining the full spectrum of job choice situations in WOP research. In doing so, we demonstrate what WOP can gain by embracing a more inclusive and multidisciplinary approach: uncovering processes in their entirety (e.g., job choice decisions of all people) and strengthening the role and legitimacy of WOP in society.     

Target- and effect-directed actions towards temporal goals: Similar mechanisms?

The goal of an action can consist of generating a change in the environment (to produce an effect) or changing one's own situation in the environment (to move to a physical target). To investigate whether the mechanisms of effect-directed and target-directed action control are similar, participants performed continuous reversal movements. They either synchronized movement reversals with regularly presented tones (temporal targets) or produced tones at reversals isochronously (temporal effects). In both goal conditions an irrelevant goal characteristic was integrated into the goal representation (loudness, Experiment 1). When targets and effects were presented within the same reversal movement, similarities were enhanced (Experiment 2). When the task posed spatial demands in addition to temporal demands, target- and effect-directed movement kinematics changed equally with tempo (Experiment 3). Correlations between target-directed and effect-directed movements in temporal variability indicated similar timing mechanisms (Experiments 1 and 2). Only gradual differences between target- and effect-directed movements were observed. We conclude that the same mechanisms of action control, including the anticipation of upcoming events, underlie effect-directed and target-directed movements. Ideomotor theories of action control should incorporate action targets as goals similar to action effects. (PsycINFO Database Record (c) 2012 APA, all rights reserved).     

Mortality salience and uncertainty: Similar effects but different processes?

Three experimental studies investigated whether death‐thoughts avoidance as a consequence of mortality salience and need for certainty as a consequence of uncertainty are two different motivational states. The results suggest that although death‐thought avoidance and need for certainty are different constructs, they share a great deal of variance (anxiety plays a pivotal mediational role in both). However, whereas the impact of uncertainty on negative attitudes towards an out‐group with different worldviews (Arabs) was mediated only by anxiety (measured retrospectively), the effect of mortality salience was mediated by both retrospective anxiety and death‐thought accessibility. These findings imply that similar effects that have been obtained by these two manipulations are, at least partly, the result of different processes. Copyright © 2013 John Wiley & Sons, Ltd.     

Couple Similarity and Marital Satisfaction: Are Similar Spouses Happier?

This study examined the role of couple similarity in spouses' marital satisfaction and affect. The associations between spousal similarity and relationship measures were examined in a sample of 248 married couples. As hypothesized, greater similarity between partners was associated with higher levels of marital satisfaction and lower levels of negative affect. In particular, similarity on the gendered personality and values domains was more strongly associated with relationship measures, whereas similarity on the attitudes and religiosity domains showed weaker and inconsistent patterns of associations. Finally, profile-based similarity tended to be a stronger and more consistent correlate of relationship measures than difference score-based similarity. The implications of these findings for processes underlying intimate relationships are discussed.     

Jealousy: Compound emotion or label for a particular situation?

Individuals generally experience several emotions when confronted with an unfaithful mate. Such observations have led some scholars to propose that jealousy is a compound emotion. The purpose of this study was to investigate whether the concept of jealousy as a combination of primary emotions is an artifact of the failure to control for the focus of concern. The subjects were 149 undergraduates who read jealousy and nonjealousy scenarios and indicated the emotions they believed the partner of a relationship experienced in response to the actions of the mate. The results indicated that manipulation of the focus of concern was a more parsimonious explanation of the results than the assumption that the subjects were basing their responses upon a subjective experience of a compound emotion.This paper was presented at the meeting of the American Psychological Association, Anaheim, California, August 1983.     

Bad or Mad? Personality disorders and legal responsibility-the German situation

Criminal offenders have a high rate of personality disorders (PDS), especially Antisocial Personality Disorders and psychopathy, but criminal acts are not necessarily the result of PD. Findings from psychiatric research suggest that the development of PD is influenced by genetic factors, that can result in deviant traits in temper, emotionality and cognitive style. There is general agreement that those peculiarities and vulnerabilities find their expression and structure only under a complex interplay of stimulating or impairing environmental influences. Do these genetic factors-or other factors-diminish a person's criminal responsibility? There is no difficulty in diagnosing PDs, but the challenging questions arise in forensic assessments of defendants for criminal responsibility who have a PD. This article discusses the German legal situation and special problems created by the term of "diminished" criminal responsibility. In contrast to the Anglo-American legal situation, the German criminal law obliges the court to order an indeterminate forensic - psychiatric confinement, in addition to punishment, if the offender had acted under diminished criminal responsibility and is now still considered to be dangerous. The convicted offender remains under the control of the criminal court during psychiatric hospitalization. The change from handling the personality disordered offender as a criminal to handling him as someone with a mental disorder creates a social option for extended state interventions, including indeterminate hospitalization.     

Discussion: Toward a social‐constructivist view of the psychoanalytic situation

The three papers by Modell, Aron, and Greenberg are discussed in terms of their relationship to a new paradigm for understanding the psychoanalytic situation. The paradigm is called social‐construct‐ivist to capture both the idea of the analyst's participation and the idea of construction of meaning. It is argued that these theorists, as well as many of the authors they cite as part of a broad movement in the field, do not consistently meet the criteria for this paradigm, although they seem to be aiming for it. An important source of inconsistency and confusion derives from the confounding of the two axes: drive‐relational and positivist‐constructivist. Many relational theorists who hold fast to the idea that analysts can grasp the truth of both their own experience and that of the patient are no closer to the constructivist point of view than was Freud. The call by Aron and Greenberg for greater attention to the patient's resisted experience of the analyst's subjectivity is discussed in terms of its potential benefits and problems. The ritualized asymmetry of the psychoanalytic situation is said to have important functions, including prevention of excessive involvement and protection of the unobjectionable positive transference and of a degree of idealization. Modell's notion of paradox, which makes the therapeutic relationship seem “real”; and “unreal”; at the same time, is seen as a special instance of the always precarious social construction of reality. It is argued, moreover, that the social and individual aspects of experience are interdependent. Neither is reducible to the other, and both should be understood, like many other issues in the new paradigm, in terms of a dialectical interplay of figure and ground in experience.     

Earliest Memories and Recent Memories of Highly Salient Events—Are They Similar?

Four- to 11-year-old children were interviewed about 2 different sorts of memories in the same home visit: recent memories of highly salient and stressful events—namely, injuries serious enough to require hospital emergency room treatment—and their earliest memories. Injury memories were scored for amount of unique information, completeness vis-à-vis a standardized injury prototype, and accuracy. Earliest memories were scored for amount of unique information, how old children had been at the time of their earliest memory, and time between their earliest memory and current age. Correlational and regression analyses showed that the 2 types of memory reports demonstrated considerable similarity in terms of unique information and completeness. Specifically, children with the most informative earliest memories had more informative as well as more complete free recalls of injury events. Such relationships between both sorts of memories suggest similar underlying processes at work when children produce memory reports, even when the length, structure, coherence, and content of those memories is about as divergent as one can imagine.     

Causes of boredom: The person,the situation,or both?

Some theories emphasize the role of the situation, some emphasize the role of the person, and some emphasize the interaction between situation and person in causing boredom. The present study examines these models by determining whether boredom propensity (person) and/or experimental condition (situation) independently or in interaction affected state boredom. The study also examined the relative contribution of behavioural activation and inhibition to state boredom. Boredom propensity and condition significantly and independently predicted state boredom, as did the interaction between behavioural inhibition and condition. Implications are discussed, including the possibility of two distinct causes of boredom.     

Similar to and/or Better than Oneself? Singles' Ideal Partner Personality Descriptions

Using the HEXACO Model of Personality, we explored two kinds of ideal partner preferences regarding personality traits, namely, to what extent people prefer partners similar to themselves (similarity preference) and to what extent people prefer partners with more desirable trait levels than themselves (aspirational assortative preference). We conducted five studies (overall N > 900) across four countries (China, Denmark, Germany, and the USA), looking at both HEXACO factors and facets, using both self‐report questionnaires and real‐life data (personal profiles from a dating website), and comprising both student and more heterogeneous samples. The results provided support for both kinds of ideal partner preferences, with important differences across traits. Specifically, similarity preference was supported by all studies concerning all HEXACO traits, and aspirational assortative preference was supported by all four self‐report studies (though not the dating website study) concerning all HEXACO traits except for Openness to Experience. Concerning differences in preferences among the HEXACO traits, similarity preference was particularly pronounced for Honesty–Humility and Openness to Experience, moderate for Agreeableness and Conscientiousness, and less pronounced for Emotionality and Extraversion. Aspirational assortative preference, by contrast, was particularly pronounced for Emotionality, Extraversion, and Agreeableness, moderate for Honesty–Humility, and inconsistent for Conscientiousness. © 2018 European Association of Personality Psychology     

The effect of a protagonist’s emotional shift on situation model construction

We examined whether readers monitored protagonists' emotional shifts and whether reader engagement influenced situation model construction. Participants read narratives that included an emotional shift in the middle of the story. In Experiment 1, participants were instructed to read stories appreciatively and to empathize with the protagonists. In Experiment 2, readers were instructed to read the stories normally, as if they were reading novels. The results from the two experiments suggest that readers monitor temporal and causal shifts as well as protagonists' emotional shifts in stories. Moreover, in Experiment 1 readers detected temporal and causal shifts regardless of th e degree oftheir engagement during the empathetic reading, while in Experiment 2 the high ego involvement group detected causal shifts during the normal reading. Thus, these results show both that readers monitor protagonists' emotional states and that reader emotional engagement c an influence situationmodel construction with normal reading.     

Is ostracism a strong situation? The influence of personality in reactions to rejection

Previous research has demonstrated that ostracism from a social group generates psychological distress. As it stands, only a few previous studies have found evidence that immediate reactions to ostracism are moderated by individual differences. Using the classic Cyberball paradigm, the present research examined a comprehensive set of personality moderators and used the largest sample size to date of lab studies evaluating the effects of ostracism (N = 270). Results indicated that when personality effects were observed in the control condition, they tended to be attenuated in the exclusion condition. More broadly, however, the findings provide little evidence that negative reactions to ostracism are strongly influenced by individual differences in personality.     

The personality triad in balance: Multidimensional individual differences in situation–behavior profiles

A new methodology is proposed to study the full personality triad including persons, situations, and responses. It is based on a model of the structural mechanism underlying behavioral data in terms of eliciting power of situations, response thresholds, as well as quantitative and/or qualitative individual differences. The model is aimed at conceptually clarifying the personality triad and makes it possible to derive individual differences in situation–behavior profiles (or behavioral signatures) starting from empirically gathered person-by-situation-by-response data. It is particularly well-suited to capture multidimensional individual differences—implying complex person by situation and/or person by response interactions—and to examine the psychological mechanisms underlying them. In an application to anger-in and anger-out in interpersonal frustrating situations, three person types were derived that were characterized in terms of distinctive behavioral signatures. Part of the differences in behavioral signatures could be explained in terms of hostile encoding and hostile expectancy processes.     

Impact of the driver’s visual engagement on situation awareness and takeover quality

During automated driving (SAE Level 3), drivers can delegate control of the vehicle and monitoring of the road to an automated system. They may then devote themselves to tasks other than driving and gradually lose situational awareness (SA). This could result in difficulty in regaining control of the vehicle when the automated system requires it. In this simulator study, the level of SA was manipulated through the time spent performing a non-driving task (NDRT), which alternated with phases where the driver could monitor the driving scene, prior to a critical takeover request (TOR). The SA at the time of TOR, the visual behaviour after TOR, and the takeover quality were analysed. The results showed that monitoring the road just before the TOR allowed the development of limited perception of the driving situation, which only partially compensated for the lack of a consolidated mental model of the situation. The quality of the recovery, assessed through the number of collisions, was consistent with the level of development of SA. The analysis of visual behaviour showed that engagement in the non-driving task at the time of TOR induced a form of perseverance in consulting the interface where the task was displayed, to the detriment of checking the mirrors. These results underline the importance of helping the driver to restore good SA well in advance of a TOR.     

Can Young Children Distinguish Abstract Expressionist Art From Superficially Similar Works by Preschoolers and Animals?

While it is sometimes claimed that abstract art requires little skill and is indistinguishable from the scribbles of young children, recent research has shown that even adults with no training in art can distinguish works by abstract expressionists from superficially similar works by children and even elephants, monkeys, and apes (Hawley-Dolan & Winner, 2011). We presented 4-7- and 8-10-year-olds with 18 paired images, one in each pair by an abstract expressionist and the other by a child or animal, and asked which they preferred and which was better. Each participant viewed the first third of the pairs unlabeled and the rest either with correct or reversed labels (artist, and child, monkey, or elephant). Three unexpected findings emerged. First, even 4-7-year-olds can distinguish works by artists from superficially similar works by children and animals when there are no labels to guide them. Second, children’s aesthetic responses are not aligned with those of adults: children often chose works labeled child or animal whether or not this label was correct, and sometimes justified their choices by crediting the effort the child or animal had made (e.g., “it’s really good for an elephant”). Finally, children, like adults, were more likely to select artist images when making quality judgments than when indicating preferences, showing that they make a distinction between intuitive preference responses and more cognitive quality judgment responses. That even preschoolers can discriminate between works by abstract expressionists and works by children and animals underscores what is wrong with the oft-heard statement, “My kid could have done that.”
