Reflexive and automatic violence: A function of aberrant perceptual inhibition

It’s commonly assumed that psychiatric violence is motivated by delusions, but here the concept of a reversed impetus is explored, to understand whether delusions are formed as ad-hoc or post-hoc rationalizations of behaviour or in advance of the actus reus. The reflexive violence model proposes that perceptual stimuli has motivational power and this may trigger unwanted actions and hallucinations. The model is based on the theory of ecological perception, where opportunities enabled by an object are cues to act. As an apple triggers a desire to eat, a gun triggers a desire to shoot. These affordances (as they are called) are part of the perceptual apparatus, they allow the direct recognition of objects – and in emergencies they enable the fastest possible reactions. Even under normal circumstances, the presence of a weapon will trigger inhibited violent impulses. The presence of a victim will also, but under normal circumstances, these affordances don’t become violent because negative action impulses are totally inhibited, whereas in psychotic illness, negative action impulses are treated as emergencies and bypass frontal inhibitory circuits. What would have been object recognition becomes a blind automatic action. A range of mental illnesses can cause inhibition to be bypassed. At its most innocuous, this causes both simple hallucinations (where the motivational power of an object is misattributed). But ecological perception may have the power to trigger serious violence also –a kind that’s devoid of motives or planning and is often shrouded in amnesia or post-rational delusions.

线索语义相容性的研究

With the studies of the Stimulus-Response Compatibility (SRC), more and more psychologists consider that the compatibility isn't only exist between stimulus and stimulus, response and response, but also any two sets in the information processing, it means that the compatibility is the basic feature of the human information processing. Research on the compatibility of the precue is a powerful evidence to support the issue. Dimension Overlap Model (Kornblum, 1990) is one of the most popular models to explain the mechanism of the SRC which focus on the dimension overlapping between the stimulus and response will activate the compatible response automatically, the compatibility effects origin from whether the compatible response prove or interference the response, the so the time course between the automatic activation and the task processing cause the dynamical time feature of the SRC (Kornblum, 1997). Yet the DO model has gotten many supports, it hasn't been tested in the paradigm of the precue task. At the same time, company with the development of the Environment Psychology, the effect of the ex-information in the environment on the inside information processing has drown much attention, does the validity probability of the cue have any influence on the cue compatibility? How about the relationship of the cue compatibility and the SRC? Research on the questions will reveal the characteristics of the human information processing, enhance the knowledge of the compatibility phenomena and resource, enlarge the field of SRC and produce more practice usage on the design of human-machine system. The mechanism and influence factors of symbolic compatibility between cue and stimulus were investigated within a precueing paradigm. The influence of the dimension overlapping relation between the cue and the stimulus, cue and the response on the reaction time were studied under the different kinds of SRC, to test whether or not it confirms the dimension overlap hypothesis, to test is there any effect of SOA and validity probability of cues on the cue compatibility. The results showed that the cue compatibility exists and owns such features: 1, It confirms the dimension overlap model that the cue which dimension overlapped with the stimulus or the response will influence the efficiency of the processing, the reaction time is shorter when the cue is congruent with the stimulus or the response that that of the incongruent cue; 2, Consistent to the automatic activation hypothesis, the time course is the important characteristic of the cue compatibility. The largest compatibility effect can be gotten from the middle duration of SOA. 3, The validity probability of cues influence the cue compatibility significantly, the strength of the cue compatibility effect grows stronger with the higher validity probability of cues. 4, The cue compatibility affect the effect of SRC, especially when the cue is compatible with the stimulus; 5, The cue compatibility has two-fold meaning, the cue-stimulus compatibility and the cue-response compatibility, the former is stronger than the later when they compete each other. In summary, the compatibility, the basic feature of human information processing, is proved by the research, and the dimension overlap model and automatic activation hypothesis is tested by the studying on the cue compatibility.

L’habilitation individuelle au travail : validation d’une mesure d’habilitation comportementale et vérification du rôle de trois facteurs de l’environnement de travail

Depuis que le concept d’habilitation (empowerment) a été introduit dans le monde du travail, il est rapidement devenu à la mode dû à ses bénéfices anticipés à la fois pour les organisations et pour les travailleurs. Toutefois, bien que l’état d’habilitation psychologique des travailleurs ainsi que ses déterminants soient bien documentés (Seibert, Wang, & Courtright, 2011), il existe peu d’outils pour évaluer de façon comportementale l’habilitation des travailleurs (Boudrias & Savoie, 2006). Cette réalité nuit aux organisations qui tentent de mettre en place des programmes d’habilitation des employés et qui souhaitent en mesurer leurs effets comportementaux. En 2006, Boudrias et Savoie ont amorcé le travail pour pallier cette lacune en créant un cadre conceptuel de l’habilitation comportementale au travail composé de deux approches distinctes, soit l’approche émergente (comportements discrétionnaires) et l’approche structurelle (implication dans la gestion du travail) et en validant un premier questionnaire permettant de mesurer l’approche émergente. La présente thèse vise à poursuivre le travail amorcé, en instrumentant la seconde approche et en poursuivant la validation du concept d’habilitation comportementale. Plus spécifiquement, la thèse vise à : a) valider un questionnaire qui mesure l’implication des employés dans la gestion de leur travail, en deux versions, à savoir une version auto-rapportée ainsi qu’une version destinée au supérieur hiérarchique; b) établir la structure factorielle de l’habilitation comportementale à l’aide des deux approches opérationnalisées; c) vérifier la spécificité du construit d’habilitation comportementale par rapport à d’autres mesures connexes (p.ex. comportements de citoyenneté organisationnelle, comportements d’innovation, comportements d’auto-leadership et d’autogestion), et d) vérifier un modèle structurel incluant trois déterminants de l’environnement de travail, à savoir le style de supervision, le soutien des collègues et la latitude décisionnelle, comme prédicteur de l’habilitation individuelle au travail, évaluée à l’aide d’une mesure d’habilitation psychologique et des mesures des deux approches d’habilitation comportementale. Pour ce faire, trois études distinctes ont été réalisées auprès de travailleurs variés et quatre échantillons ont été constitués dont trois comprenant uniquement des données auto-rapportées (N = 274, 104, 249) et un quatrième incluant aussi des données rapportées par le supérieur (N = 151). Les résultats des analyses factorielles confirmatoires démontrent que la structure de l’instrument d’implication dans la gestion ainsi que celle de l’habilitation comportementale composée des deux approches sont constantes d’un échantillon à l’autre et dans ses deux versions. De plus, les propriétés métriques du questionnaire validé sont satisfaisantes. D’autre part, les résultats des analyses corrélationnelles indiquent que les mesures d’habilitation comportementale présentent une validité discriminante par rapport à des mesures d’autres construits connexes. Enfin, les analyses acheminatoires pour vérifier le modèle structurel anticipé indiquent que l’habilitation psychologique agit comme variable médiatrice dans les relations entre, d’une part, la latitude décisionnelle et les pratiques de gestion des supérieurs, et, d’autre part, les deux approches d’habilitation comportementale. Le soutien des collègues, de son côté, n’est pas relié à l’habilitation des travailleurs.

Um enfoque psicológico da educação ambiental no contexto da gestão: uma experiência de Fernando de Noronha

Currently, many companies pay attention to the necessities of change of attitude in relation to the use of the natural resources and the environment quality of its products, mainly to keep a positive and competitive image in the market. This new concept of management associates the productive activities to the care with environment using the education of environment as a tool of programs of qualification directed toward the promotion of pro-environment behaviors. For effectiveness of this management it is essential the attachment of the employees and the major understanding of the importance of the preservation of the environment. This was the objective of the qualification process carried out in a lodge in Fernando de Noronha island. The purpose of this study, therefore, was to verify the power of this management system which fulfills the objectives of the environmental education. It was applied questionnaires to employees of three Inns and carried out a interview, in one Inn, with the participants of the program of qualification. The analysis of the data showed that the actions as care with the environment are strongly associates to the management system, which includes garbage control, as well water economy. It was observed that the environment accomplishment (EcoAntro) of the employees with environment decreases in proportion to their qualification. In the same way, as higher the instruction level, of the speaker and/or of the father, less is the apathy for environmental questions. It was also noticed that the knowledge about the development sustainability was very poorly used by the interviewed. The pro-environment behavior mentioned before, is not necessarily related to a local autonomy posture that could express a behavior related to job but not to environment it self. Therefore, a complete understanding about the reverberation of environment information an all the placed factors in a life stile facing a construction of sustainability remains as a question to be studied in future researches

Representations of workplace psychological harassment in print news media

OBJECTIVE: To analyze discourses on workplace psychological harassment in print media. METHODOLOGICAL PROCEDURES: Documental study on workplace psychological harassment that analyzed news stories published in three major newspapers of the State of Sao Paulo (southeastern Brazil) between 1990 and 2008. Discourse analysis was performed to identify discursive practices that reflect the phenomenon of psychological harassment in today's society, explanations for its occurrence and impact on workers' health. RESULT ANALYSIS: This theme emerged in the media through the dissemination of books, academic research production and laws. It was initially published in general news then in jobs and/or business sections. Discourses on compensation and precautionary business practices and coping strategies are widespread. Health-related aspects are foregone under the prevailing money-based rationale. Corporate cultures are permissive regarding psychological harassment and conflicts are escalated while working to achieve goals and results. Indifference, embarrassment, ridicule and demean were common in the news stories analyzed. CONCLUSIONS: The causal explanations of workplace harassment tend to have a psychological interpretation with emphasis on individual and behavioral characteristics, and minimizing a collective approach. The discourses analyzed trivialized harassment by creating caricatures of the actors involved. People apprehend its psychological content and stigmatization which contributes to making workplace harassment an accepted practice and trivializing work-related violence.

Teacher praise and feedback and students’ perceptions of the classroom environment

The relationships between teacher praise and feedback, and students’ perceptions of the classroom environment were investigated in six rural elementary schools (n 5 747). The Teacher Feedback Scale and My Classroom Scale were developed as part of this study and used to collect the data. Structural equation modelling was used to test a hypothesised model. The results indicated that negative teacher feedback and effort feedback were both related to students’ relationships with their teachers, while ability feedback was associated with perceptions of the classroom environment. Praise was not related to classroom environment or teacher–student relationships. Significant age and gender differences were found. Additionally, differences were found between students who were satisfied with their classroom and those who were dissatisfied. Satisfied students received more general praise, general ability feedback, effort feedback and less negative teacher feedback when compared to dissatisfied students. Research studies have emphasised the influence of signicicant adults (teachers and parents) on students’ personal development (Porlier et al., 1999) and the importance of significant others’ verbal statements when directed at children (Burnett, 1996a). The relationships between negative and positive statements made by teachers, parents, peers and siblings and children’s self-talk have been investigated (Burnett, 1996a) and positive statements (praise) have been found to be more beneficial than verbal criticism (Burnett, 1999). The quality of life in the classroom in recent times has been considered of great importance to students (Thorp et al., 1994) and this is recognised by Baker (1999) who reported a relationship between students’ satisfaction with the learning environment, and differential teacher feedback and praise. This study investigated the relationships between teacher praise and feedback, and how students perceived their classroom and their relationship with their teacher.

The relative impact of work-related stress, life stress and driving environment stress on driving outcomes

Previous research has shown the association between stress and crash involvement. The impact of stress on road safety may also be mediated by behaviours including cognitive lapses, errors, and intentional traffic violations. This study aimed to provide a further understanding of the impact that stress from different sources may have upon driving behaviour and road safety. It is asserted that both stress extraneous to the driving environment and stress directly elicited by driving must be considered part of a dynamic system that may have a negative impact on driving behaviours. Two hundred and forty-seven public sector employees from Queensland, Australia, completed self-report measures examining demographics, subjective work-related stress, daily hassles, and aspects of general mental health. Additionally, the Driver Behaviour Questionnaire (DBQ) and the Driver Stress Inventory (DSI) were administered. All participants drove for work purposes regularly, however the study did not specifically focus on full-time professional drivers. Confirmatory factor analysis of the predictor variables revealed three factors: DSI negative affect; DSI risk taking; and extraneous influences (daily hassles, work-related stress, and general mental health). Moderate intercorrelations were found between each of these factors confirming the ‘spillover’ effect. That is, driver stress is reciprocally related to stress in other domains including work and domestic life. Structural equation modelling (SEM) showed that the DSI negative affect factor influenced both lapses and errors, whereas the DSI risk-taking factor was the strongest influence on violations. The SEMs also confirmed that daily hassles extraneous to the driving environment may influence DBQ lapses and violations independently. Accordingly, interventions may be developed to increase driver awareness of the dangers of excessive emotional responses to both driving events and daily hassles (e.g. driving fast to ‘blow off steam’ after an argument). They may also train more effective strategies for self-regulation of emotion and coping when encountering stressful situations on the road.

Dangers of the after-dark wonderlands : Part A - A review of the impact of physical environment design on nightclub violence

Nightclubs are businesses. Their business is pleasure; however pleasure has its price. People have become increasingly concerned about the problems of violence in society but why do higher levels of violence occur in nightclubs despite the established patterns of behaviour that dictates how we socialise and act? In response, researchers have focused on identifying social and situational factors that may contribute to violence from a government perspective, focusing on a variety of specific issues ranging from financial standpoints with effective target marketing strategies to legal obligations of supplying alcohol and abiding regulatory conditions. There is little research into specific design properties that can determine design standards to ensure/improve the physical design of nightclub environments to reduce patron violence. To address this gap, this current article aims to understand how people experience and respond to the physical environment of nightclubs and how these spaces influence their behaviour. The first section of this paper examines the background on nightclubs and theories concerning the influence of pleasure. The second section of this paper details the findings of existing studies that have examined the nightlife context and the various factors that influence patron violence. The main finding of this paper is that although alcohol likely plays a contributing role in aggressive patron behaviour, there is evidence that the relationship is moderated by a number of significant factors relating to the characteristics of the drinking environment such as: physical comfort; the degree of overall 'permissiveness‘ in the establishment; crowding; and physical environmental elements most influenced by day to-day management practices such as lighting, ventilation, cleanliness and seating arrangements. The findings from this paper have been used to develop a framework to guide exploratory research on how specific elements of the physical environment of nightclubs have an impact on elevated patron aggression and assault (Koleczko & Garcia Hansen, 2011).

Dangers of the after-dark wonderlands : Part B - A review of the impact of the physical environment design on nightclub violence

Violence in nightclubs is a serious problem that has the Australian government launching multimillion dollar drinking campaigns. Research on nightclub violence has focused on identifying contributing social and environmental factors, with many concentrating on a variety of specific issues ranging from financial standpoints with effective target marketing strategies to legal obligations of supplying alcohol and abiding regulatory conditions. Moreover, existing research suggests that there is no single factor that directly affects the rate violence in licensed venues. As detailed in the review paper of Koleczko and Garcia Hansen (2011), there is little research about the physical environment of nightclubs and which specific design properties can be used to determine design standards to ensure/improve the physical design of nightclub environments to reduce patron violence. This current study seeks to address this omission by reporting on a series of interviews with participants from management and design domains. Featured case studies are both located in Fortitude Valley, a Mecca for party-goers and the busiest nightclub district in Queensland. The results and analysis support the conclusions that a number of elements of the physical environment influence elevated patron aggression and assault.

Enhancing employment services for people with severe mental illness: the challenge of the Australian service environment

Objectives:  Comparatively few people with severe mental illness are employed despite evidence that many people within this group wish to obtain, can obtain and sustain employment, and that employment can contribute to recovery. This investigation aimed to: (i) describe the current policy and service environment within which people with severe mental illness receive employment services; (ii) identify evidence-based practices that improve employment outcomes for people with severe mental illness; (iii) determine the extent to which the current Australian policy environment is consistent with the implementation of evidence-based employment services for people with severe mental illness; and (iv) identify methods and priorities for enhancing employment services for Australians with severe mental illness through implementation of evidence-based practices. Method:  Current Australian practices were identified, having reference to policy and legal documents, funding body requirements and anecdotal reports. Evidence-based employment services for people with severe mental illness were identified through examination of published reviews and the results of recent controlled trials. Results:  Current policy settings support the provision of employment services for people with severe mental illness separate from clinical services. Recent studies have identified integration of clinical and employment services as a major factor in the effectiveness of employment services. This is usually achieved through co-location of employment and mental health services. Conclusions:  Optimal evidence-based employment services are needed by Australians with severe mental illness. Providing optimal services is a challenge in the current policy environment. Service integration may be achieved through enhanced intersectoral links between employment and mental health service providers as well as by co-locating employment specialists within a mental health care setting.

The Impact of Parental Attachment on Adolescent Perception of the School Environment and School Connectedness

The extent to which students feel accepted, valued, respected and included in the school has recently surfaced as one of the most important predictors of adolescent mental health (particularly depressive symptoms). The school environment is an established predictor of school connectedness, but we set out to examine whether parental attachment predicts both adolescents' perception of the school environment and school connectedness. A study of 171 high school students from years 8 to 12 showed that parent attachment strongly predicted both. We also confirmed that the relationship between parent attachment and school connectedness is not a direct one but that parent attachment influences individual differences in the way adolescents perceive the school environment, which in turn influences school connectedness. This finding shows how multiple systems might be interlinked in influencing wellbeing in adolescents, and confirms the importance of intervening at the double level of both the family and the school system.

Children and the environment

Children and the environment cover a broad, interdisciplinary field of research and practice. The social sciences often use the word “environment” to mean the social, political, or economic context of children’s lives, but this bibliography covers physical settings. It focuses on a place-based scale that children can see, hear, taste, smell, touch, and navigate: not large, abstract scales such as national identities or population dynamics, or small scales such as environmental impacts on genes or cell functions. Attention to the everyday settings of children’s lives grew in the 18th century, when Romantic literature introduced the theme of children and nature. In the 19th century, concern for children’s welfare included an interest in conditions for children in burgeoning industrial cities, and justifications for early streetcar and railroad suburbs included claims that they would save children from the dangers of cities and provide the healthful benefits of natural surroundings. In the 20th century, academic disciplines developed different lines of inquiry about the impact of the physical environment on children and how children relate to places: ethnographic studies of children in different parts of the world in the fields of anthropology and geography; sociological studies of different populations of children in different settings; educational research on the learning opportunities that different school and out-of-school settings afford; medical research to understand disease vectors and the impact of pollutants on children; and efforts in the field of environment and behavior research more broadly, to understand how built and designed environments affect children physically, cognitively, socially, and emotionally. At the beginning of the 21st century, children and the environment is an active area of inquiry seeking to understand rapidly changing conditions for children as the world urbanizes, opportunities for free play outdoors and independent mobility erode in many parts of the world, media environments consume more of children’s time, and awareness grows that children need opportunities to contribute to creating sustainable societies.

Ecological dynamics as a theoretical framework for development of sustainable behaviours towards the environment

This paper proposes how the theoretical framework of ecological dynamics can provide an influential model of the learner and the learning process to pre-empt effective behaviour changes. Here we argue that ecological dynamics supports a well established model of the learner ideally suited to the environmental education context because of its emphasis on the learner-environment relationship. The model stems from perspectives on behaviour change in ecological psychology and dynamical systems theory. The salient points of the model are highlighted for educators interested in manipulating environmental constraints in the learning process, with the aim of designing effective learning programs in environmental education. We conclude by providing generic principles of application which might define the learning process in environmental education programs.
