- Agriculture technology is moving toward automation, placing operators in a supervisory role. This change in operator workload may lead to increased stress and higher mental load, resulting in reduced attention and hence greater risk of illness or injury to humans and damage to equipment. This study investigated the use of easily applicable equipment to measure mental load. Three methods were used to measure the mental load on machine operators: heart rate monitoring, two types of electroencephalograph (EEG) evaluation, and an assessment protocol. Three driving exercises (general driving, slalom driving, and loading) and a counting exercise were used in a driving simulator to create different levels of mental load. Due to the number of exercises, a single-scale assessment protocol was used to save time. We found that only the assessment protocol gave clear results and would work well as an evaluation tool. The heart rate and EEG measurements did not provide clear data for mental load assessment.

- Environmental intolerance (EI) is a condition characterized by low tolerance to environmental stimuli at levels that would not affect most people. EI is an ill-defined condition from which sufferers experience highly individual multisystem symptoms following exposure from specific environmental sources. Most research on EI is conducted using cross sectional approaches, however, longitudinal approaches that capture daily exposure are needed to fully understand how EI develops and change over time. This paper describes an app that was developed that can be used with most smartphones and, in conjunction with a website, can be used to collect symptoms and ratings of discomfort in the field as well as qualitative reports of the incident that triggered the discomfort.

Some observations about ecological momentary assessment of real-world exposure to unpleasant sound and smell

- Retrospective questionnaire methodology designed to survey individuals' exposures and experiences to real-world stimuli is susceptible various types of recall biases. EcologicalMomentary Assessment (EMA) investigates individuals´ behaviour and experiences in real time by asking them to document their experience as soon as possible after exposure. This presentation reports some preliminary results from a study where a total of 114 participants in northern Sweden, comprised of 53 sound or smell hypersensitive persons (age: M=56, SD=12.7) and 61 non-hypersensitive individuals (age: M=61.1, SD=10.8), were surveyed through a questionnaire twice with a three-month period in between about exposure and experiences with unpleasant sounds and smells. During the three-month period, participates used a smartphone app to document incidents and experiences of unpleasant sounds between questionnaires. This presentation will discuss the similarities and differences observed between the results of the questionnaires and EMA as well as address methodological advantages and challenges presented by collecting EMA using a smartphone app system.

The impact of spoken action words on performance in a cross-modal oddball task

Tidskriftsartikel (refereegranskat)abstract
- In this study a cross-modal oddball task was employed to study the effect that words spokeneither non-urgently or urgently would have on a digit categorization task and if women wouldexhibit greater behavioral inhibitory control. The words were unrelated to the task itself, butrelated to the action required to complete the task. Forty participants (21 women) conducteda computerized categorization task while exposed to a sinewave tone as a standard stimulus(75% of the trials) or a to-be ignored word (press, stop) spoken either non-urgently orurgently as unexpected auditory deviant stimulus (6.25% trials for each category). Urgentwords had sharp intonation and an average fundamental frequency (F0) ranging from 191.9(stop) to 204.6 (press) Hz. Non-urgent words had low intonation with average F0 rangingfrom 103.9.9 (stop) to 120.3 (press) Hz. As expected, deviant distraction and longerresponse times were found by exposure to the word stop, but deviant distraction was notfound to be significant with the word press or due to intonation. While the results showedthat women had in general longer reaction times, there were no gender differences foundrelated to the deviant distraction caused by word or intonation. The present results do notsupport the hypothesis that women have greater behavioral inhibitory control, but there wasevidence that the meaning of the word could influence response times.

On the relationship between computer simulation training and the development of practical knowing in police education :

Tidskriftsartikel (refereegranskat)abstract
- Purpose: The purpose of this paper is to focus on the practical knowing that is central in police education. Drawing on perspectives about tacit knowledge and embodied learning (e.g. Merleau-Ponty, 1945/1997; Polanyi, 1966; Argyris and Schön, 1974) as well as empirical examples, this paper discusses the design of and what can be expected from computer simulation training for the development of police students’ professional knowing.Design/methodology/approach: The discussion is based on lessons learned from working with two different computer simulation training situations designed to prepare the students for an upcoming practical training by facilitating the understanding of complex situations as they should be handled in the physical training situation.Findings: The experiences from the training sessions showed that the different characteristics of the simulations mediate how the training session was performed, e.g., unplanned trial and error vs focused and attentive, but also group discussions about how to act and appropriate actions in relation to the situation to be solved in the simulation.Originality/value: Based on the lessons learned from working with the two different computer simulations, it is posited that the use of computer simulations for practical scenario training is a complex endeavor that needs, in various degrees, to be supported by pedagogical steering. The design of computer simulation training (both the simulation and how the training is designed and performed) need to consider the specific aspects that surround tacit knowledge and embodied learning in the “real sense” (anchored to the practical training) to be of relevance for police students development of professional knowing.

Based on the the lessons learned fromworking with computer simulations in police education we argue thatcomputer simulations can be a useful aid for practical training, but they cannotreplace exercises in scenario training or drill exercises.
