  There has been a recent surge of interest in social chatbots, and human–chatbot relationships (HCRs) are becoming more prevalent, but little knowledge exists on how HCRs develop and may impact the broader social context of the users. Guided by Social Penetration Theory, we interviewed 18 participants, all of whom had developed a friendship with a social chatbot named Replika, to understand the HCR development process. We find that at the outset, HCRs typically have a superficial character motivated by the users' curiosity. The evolving HCRs are characterised by substantial affective exploration and engagement as the users' trust and engagement in self-disclosure increase. As the relationship evolves to a stable state, the frequency of interactions may decrease, but the relationship can still be seen as having substantial affective and social value. The relationship with the social chatbot was found to be rewarding to its users, positively impacting the participants' perceived wellbeing. Key chatbot characteristics facilitating relationship development included the chatbot being seen as accepting, understanding and non-judgmental. The perceived impact on the users' broader social context was mixed, and a sense of stigma associated with HCRs was reported. We propose an initial model representing the HCR development identified in this study and suggest avenues for future research.

  BACKGROUND: The literature discussing visual ergonomics often mention that human vision is adapted to light emitted by the sun. However, the theoretical and practical implications of this viewpoint is seldom discussed and taken into account. OBJECTIVE: The paper discusses some of the main theoretical implications of an evolutionary approach to visual ergonomics. DISCUSSION: Based on interactional theory and ideas from ecological psychology an evolutionary stress model is proposed as a theoretical framework for future research in ergonomics and human factors. The model stresses the importance of developing work environments that fits with our evolutionary adaptations. In accordance with evolutionary psychology, the environment of evolutionary adaptedness (EEA) and evolutionarily-novel environments (EN) are used as key concepts. Using work with visual display units (VDU) as an example, the paper discusses how this knowledge can be utilized in an ergonomic analysis of risk factors in the work environment. CONCLUSION: The paper emphasises the importance of incorporating evolutionary theory in the field of ergonomics. Further, the paper encourages scientific practices that further our understanding of any phenomena beyond the borders of traditional proximal explanations.

  Employees differ in their apperception of open plan offices. Despite this, individual differences have been sparsely treated in the literature discussing effects of office design. The aim of the present study was to investigate how stimulus screening, working memory, and attention interrelate and affect important factors in the work environment. The study utilized a cross sectional design. Participants (N=35) were recruited among employees in four organizations. Working memory was assessed bye means of the Operation –Word Span Task (OSPAN) while attention was measured by the d2 test of attention. Dependent variables were job stress, job involvement, organizational commitment, and need for recovery. The results showed a main affect of stimulus screening on need for recovery and one subscale of organizational commitment. A main effect was also found for fluctuation rate across trials, a sub measure of attention, on need for recovery. The results revealed no indication of any mediator or moderator effects of either working memory or attention, on stimulus screening, for any of the dependent variables. Thus, the effect of stimulus screening seems not to be explained through individual differences in cognitive processes.

  Estimates about uncertain quantities can be expressed in terms of lower limits (more than x, minimum x), or upper limits (less than y, maximum y). It has been shown that lower limit statements generally occur much more often than upper limit statements (Halberg & Teigen, in press). However, in a conversational context, preferences for upper and lower limit statements will be moderated by the concerns of the interlocutors. We report three studies asking speakers and listeners about their preferences for lower and upper limit statements, in the domains of distances, durations, and prices. It appears that travellers prefer information about maximum distances and maximum durations, and buyers (but not sellers) prefer to be told about maximum prices and maximum delivery times. Mistaken maxima are at the same time regarded as more “wrong” than mistaken minima. However, this preference for “worst case” information is not necessarily shared by providers of information (advisors), who are also concerned about being blamed if wrong.

  People often describe uncertain quantities by suggesting a lower or upper limit of an uncertainty interval, rather than the complete range. Five studies are reported, which demonstrate how interval limits function as provisional reference points (PRP), conferring evaluative meanings to the target objects, by suggesting downward or upward comparisons. Thus, a price above X appears expensive, whereas a price below Y appears cheap, even when Y > X. This can give rise to framing effects: a purchase can appear to be recommended or advised against, and a seller can appear as optimistic or pessimistic, and, more generally, an estimate can indicate abundance or scarcity, depending upon which boundary (upper or lower) that is selected. Furthermore, inclusive lower bounds (minimum, at least) and upper bounds (maximum, at most) differ from exclusive lower (more than, above) and upper bounds (less than, below), by suggesting possible (likely) rather than implausible (unlikely) values.

  Uncertain quantities can be described by single-point estimates of lower interval bounds(X1), upper interval bounds (X2), two-bound estimates (separate estimates of X1 and X2),and by ranges (X1-X2). A price estimation task showed that single-bound estimates phrased as ‘‘T costs more than X1’’ and ‘‘T costs less than X2,’’ yielded much larger intervals than ‘‘minimum X1’’ and ‘‘maximum X2.’’ This difference can be attributed to exclusive interpretations of X1 and X2 in the first case (X1 and X2 are unlikely values), and inclusive interpretations in the second (X1 and X2 are likely values). This pattern of results was replicated in other domains where participants estimated single targets. When they estimated a distribution of targets, the pattern was reversed. ‘‘Minimum’’ and ‘‘maximum’’ values of variable quantities (e.g., flight prices) were found to delimit larger intervals than ‘‘more than’’ and ‘‘less than’’ estimates.

  The scientific basis for ergonomics recommendations for controls has usually not been related to active goal-directed use. The present experiment tests how different knob sizes and torques affect operator performance. The task employed is to control a pointer by the use of a control knob, and is as such an experimentally defined goal-directed task relevant to machine systems in general. Duration of use, error associated with use (overshooting of the goal area) and movement reproduction were used as performance measures. Significant differences between knob sizes were found for movement reproduction. High torques led to less overshooting as opposed to low torques. The results from duration of use showed a tendency that the differences between knob sizes were reduced from the first iteration to the second iteration. The present results indicate that the ergonomically recommended ranges of knob sizes might differently affect operator performance.

  Lower monitor placements, with gaze angles to the centre of the screen 30�45 below the horizontal line are proposed as an alternative to higher monitor placements advocated by prevailing guidelines. A scientific basis for this proposition has been established within a comprehensive theoretical framework, founded on an ecological systemic approach to vision. A review of the literature shows reduced visual strain and a strong tendency towards reduced symptomatology in subjects working with downward gaze. Increased musculoskeletal load is not evident in m. trapezius, while a clinically insignificant increase might be present in some other neck and shoulder muscles. Research studying subjective preferences is inconclusive at present. The evidence indicates that lower monitor placements result in less strain on the total network of muscles involved in visual display unit (VDU) work.

  The claim that VDU-screen filters improve health by reducing exposure to electrical fields and/or improving screen legibility was investigated by introducing VDU screen filters into an office environment. The study design was quasi-experimental, with the first part conducted according to a simulated control group design with one intervention and one control group. In the second part, which served as a partly switched replication, the control group also received screen filters. The first group continued their use. The dependent measures were sick leave, productivity. subjective symptoms, and musculoskeletal condition. Subjectively-reported symptom improvement was found in the group that received screen filters during the initial part of the study, but that was followed by an aggravation of symptoms during the second part for the same group. No effect was observed in the control group in either part of the study. The discontinuity observed between the study parts indicates that factors other than VDU-screen filter use were respon-sible for the results. However, the results appear to be explained by subject reactivity, i.e. the Hawthorne effect. The results caution against premature con-clu-sions drawn from short-term interventions and emphasise the need for a better understanding of the various psychological and task-related factors that influence subjects.

  Organizational citizenship behavior (OCB) has been found to vary over time, but its longitudinal development has remained unexplored. Drawing from event system theory and human capital theory, we investigate the development of OCB over time and contextualize it with events in the organization that affect employees and their work tasks and with resources provided through human resource management (HRM) practices. The longitudinal growth model was tested in a sample of 205 employees with monthly measures over one year. For each event, we found distinctive trajectories of OCB. Furthermore, the HRM practices of selective staffing and training influenced OCB at the onset of an event, whereas the HRM practices of decision making, performance management, and promotional opportunities determined the level and the development of OCB after the event reorganization. Our contextual view of the development of OCB helps in understanding what motivates employees to perform OCB and what resources support discretionary behavior.

  Uncertain or approximate quantities are in daily life often described by lower or upper limit estimates: ?more than 120 people killed?, ?a maximum 100-words abstract?. These estimates can be exclusive (more than, less than) or inclusive (minimum, maximum), leading to widely different intervals, dependent upon whether the estimates concern a single value or a distribution. Lower and upper limits pragmatically function as reference points, leading to framing effects. Shoes that cost ?more than X? are considered expensive, ?less than Y? implies that they are cheap, even when Y > X. Sales ?above X? indicate a rising trend, regardless of X.

  Inconsistent results are reported by studies investigating subjective preference of vertical line-of-sight during nearwork. However, these studies are constrained by the short time allocated to familiarisation with unusual target/monitor locations. In the present work, subjective preferences were studied two years after the termination of a one-year field experiment, investigating the effect of different line-of-sight angle in VDU work. The results showed that most participants preferred to leave the desktop and monitor adjustments as they were set in the original experiment. The result stress the decisive importance of psychological factors and adjustment time and, thereby, questions the validity of the short time periods usually given to become accustomed to new monitor placements in studies investigating preferred line-of-sight in VDU-work.

  Based on an ecological analysis of the visual system, a systemic model is proposed linking visual stress and symptoms in other parts of the body. The model links the interaction between the oculo-motor system and other body muscles to the slow-acting mechanism of Scohr's two-step theory of vergence control. Implications of the model have been examined in a field study. The results indicate that increased closeness between natural near work and VDU-work yield reduced symptoma-tology not only for eye symptoms but also for visually related symptoms in a broader sense.

  Lower monitor placements, with gaze angles to the centre of the screen 30º- 45º below the horizontal line are proposed as an alternative to higher monitor placements advocated by prevailing guidelines. A scientific basis for this proposition has been established within a compre-hensive theoretical framework, founded on an ecological systemic approach to vision. A review of the literature shows reduced visual strain and a strong tendency toward reduced symptomatology in subjects working with downward gaze. Increased musculoskeletal load is not evident in m. trapezius, while a clinically insignificant increase might be present in some other the neck and shoulder muscles. Research studying subjective preferences is inconclusive at present. The evidence indicates that lower monitor place-ments result in less strain on the total network of muscles involved in VDU work.

  The implementation of information technology (IT) in modern work life has lead to a growing concern about negative health effects associated with visual display units (VDU). Despite abundant research and honourable ergonomic effort within this field, it has proven difficult to obtain substantial health effects from traditional ergonomic optimisations. The aim of this dissertation was to further the understanding of some specific factors associated with health problems in VDU work. Further, the aim was to contribute to the general understanding of the aetiology behind health problems and behavioural changes associated with VDU work. To accomplish this, four empirical studies were conducted, one laboratory study and three field studies. Paper I addressed questions about workstation design. The results show that forearm support reduces musculoskeletal load for both mouse work and keyboarding. Moreover, shifting between sitting and standing appears to be beneficial for the musculoskeletal system. Paper II discussed possible health effects from protective VDU screen filters. The results did not demonstrate any remedial effect of such filters. The results point to participant reactivity as a plausible explanation for positive findings previously reported in short-term studies. Paper III addressed questions about vertical monitor placement. That study supported previous laboratory research by showing a range of positive health effects from lower monitor placements. Paper IV discussed the importance of office lighting. The results revealed that proportions of indirect and direct lighting did not affect health and behaviour, provided that glare was removed as a source of environmental stress. The results of the four papers were interpreted within a new theoretical framework, the Evolutionary Stress Model (ESM). The ESM stresses the importance of developing work environments that fits with our evolutionary adaptations. Taken together, the presented results concur with predictions made from this model. On this basis, it seems pertinent to recommend the model as a theoretical framework for future research in ergonomics and human factors.

  Intervensjonsstudien "Den elektroniske skjermarbeidsplassen" har vært gjennomført som en toårig eksperimentell feltstudie der formålet har vært å utvikle kunnskap om faktorer som påvirker belastningsforholdene ved skjermarbeid. Konkret har man har undersøkt helse-effekter av optimalisering av kontormiljø med nedsenket skjerm versus optimalisering av kontormiljø med normalplassert skjerm. I tillegg har man undersøkt helse-effekter av optisk fullkorrek-sjon versus standard optometrisk korreksjonsprosedyre. Intervensjonene har vært gjennomført serielt, noe som har gitt muligheter for å be-regne enkelt-effekter av hver faktor i tillegg til even--tuelle sam-spillseffekter. Resultatene har vært samlet inn ved følgende metoder: Et selv-administrert spørreskjema, en klinisk helse-undersøkelse, en optometrisk undersøkelse samt EMG-opptak under 45 minutter normal-arbeid. Resultatene fra skjermintervensjonen viser redusert plageut-vikling blant skjermarbeidere med nedsenket skjerm både på subjektive og objektive kriterier. Når det gjelder gruppen med standard skjermplassering finner vi endringer i begge retninger. Det er derfor mer usikkert om optimaliseringen i henhold til gjeldende standard har gitt redu-sert plage-utvikling. Resul-tatene fra den optiske intervensjonen viser at effekten av arbeids-plass-briller er hovedsakelig knyttet til synsplager, med mest markert effekt i arbeids-situa-sjonen. Når det gjelder forskjeller mellom de to korreksjons-regimene gjorde forhold i intervensjonsstudien det umulig å foreta en slik sammenligning på en tilfredsstillende måte. Det ble ikke påvist noen interaksjonseffekt mellom korreksjon og skjermposisjon.
