On-road trust and perceived risk in Level 2 automation

To encourage appropriate use of driving automation, we need to understand and monitor driver’s trust and risk perception. We examined (1) how trust and perceived risk are affected by automation, driving conditions and experience and (2) how well perceived risk can be inferred from behaviour and physiology at three levels: over traffic conditions, aggregated risk events, and individual risk events.30 users with and without automation experience drove a Toyota Corolla with driving support. Safety attitude, subjective ratings, behaviour and physiology were examined.Driving support encouraged a positive safety attitude and active driver involvement. It reduced latent hazards while maintaining saliently perceived risks. Drivers frequently overruled lane centring (3.1 times/minute) and kept their feet on or above the pedals using ACC (65.8% of time). They comfortably used support on curvy motorways and monotonic and congested highways but less in unstable traffic and on roundabouts. They trusted the automation 65.4%, perceived 36.0% risk, acknowledged the need to monitor and would not engage in more secondary tasks than during manual driving.Trust-in situation reduced 2.0% when using automation. It was 8.2% higher than trust-in-automation, presumably due to driver self-confidence. Driving conditions or conflicts between driver and automation did not affect trust-in-automation.At the traffic condition level, physiology showed weak and partially counter-intuitive effects. For aggregated risk events, skin conductance had the clearest response but was discernible from baseline in  < 50%. Pupil dilation and heart rate only increased with strong braking and active lane departure assist. For individual risk events, a CNN classifier could not identify risk events from physiology. We conclude that GSR, heart rate and pupil dilation respond to perceived risk, but lack specificity to monitor it on individual events.     

Attentional biases to threat in social anxiety disorder: time to focus our attention elsewhere?

Background: Cognitive models propose that attentional biases to threat contribute to the maintenance of social anxiety disorder (SAD). However, the specific characteristics of such biases are still object to debate.

Objectives: The current study aimed to disentangle effects of trait and state social anxiety on attention allocation towards social stimuli.

Methods: Participants with SAD (n?=?67) and healthy controls (n?=?62) completed three visual search tasks while their eye movements were recorded. Half of the participants in each group were randomly assigned to a state anxiety induction.

Results: Contrary to our predictions, neither trait nor state social anxiety was associated with a facilitated attention to or a delayed disengagement from threat. However, participants with SAD did show reduced fixation durations for threatening stimuli, indicating an avoidance of threat. Induction of state anxiety led to an increased distractibility by threat.

Conclusions: We suggest that attention allocation in SAD is characterized by an avoidant rather than a vigilant attentional bias. Accordingly, our results contradict previous results that associate SAD with facilitated attention to threat and existing approaches to modify attentional biases, that aim to decrease attention towards threatening stimuli.     

Happiness,pleasures, and emotions

In The Pursuit of Unhappiness, Daniel Haybron has defended an emotional state theory of happiness, according to which happiness consists in a broadly positive balance of emotions, moods, and mood propensities. In this paper, I argue that Haybron’s theory should be modified in two ways. First, contra Haybron, I argue that sensory pleasures should be regarded as constituents of happiness, alongside emotions and moods. I do this by showing that sensory pleasures are sufficiently similar to emotions for them to be included within the class of happiness-constituting states. Second, I argue that a plausible theory of happiness should not include mood propensities, since their inclusion is either counterintuitive or unnecessary.     

Occurrent states

The distinction between occurrent and non-occurrent mental states is frequently appealed to by contemporary philosophers, but it has never been explicated in any significant detail. In the literature, two accounts of the distinction are commonly presupposed (and occasionally stated explicitly). One is that occurrent states are conscious states. The other is that non-occurrent states are dispositional states, and thus that occurrent states are manifestations of dispositions. I argue that neither of these accounts is adequate, and therefore that another account is needed. I propose that occurrent states are active states.     

Lifeboat politics in the Pacific: Affect and the ripples and shimmers of a migrant saturated future

Affect is explored in relation to the governance of irregular migrants and asylum seekers that turn such vulnerable individuals into a feared category. How are emotions as practices developed, fostered and enacted? The examples developed in the article focus on ‘illegal maritime arrivals’ (asylum seekers arriving by boat) and the emotionally charged response to them in Australia. The article argues that the state, far from embodying a detached and neutral arbiter utilising various steering mechanisms of care and due process, instead governs through fear and anxiety generated in relation to outsiders. The state draws on, and indeed creates, dispositions and feelings, generating a distinct politics of affect. The motif of the lifeboat is an example of a diversion from the anxieties and fears in everyday life; a metaphor for scarcity and a battle for survival. The asylum seeker as ‘illegal maritime arrival’ (boat person) is the exemplar of such a lifeboat politics in the Australian case.     

The triumph of American psychiatry: How it created the modern therapeutic state

Over the past 170 years, American psychiatry has progressively asserted its authority over a larger segment of the American population. From the mid-1800s to the end of World War II, psychiatry had authority over the asylum population, which markedly increased in the first half of the twentieth century due to the influence of eugenics, an ideology that argued the ‘mentally ill’ had to be segregated from society. After the war, American psychiatry adopted Freudian conceptions of mental disorders, which enabled it to begin treating people in the community who were ‘neurotic’ in some way, which dramatically expanded its influence in society. Then, in the 1970s, when many in American society were questioning psychiatry’s legitimacy as a branch of medicine, the American Psychiatric Association (APA) responded by adopting a disease model for diagnosing mental disorders, which it set forth in the third edition of its Diagnostic and Statistical Manual. There were no scientific discoveries that led to this new model, but soon the APA was informing the American public that mental disorders were diseases of the brain, and that psychiatric drugs helped fix those diseases, ‘like insulin for diabetes.’ The APA, in concert with pharmaceutical companies, has successfully exported this belief system to much of the developed world. In order to break free of this ‘therapeutic state,’ the public needs to understand the history of how it came to be, and see the social injury it has caused.     

Underlying correlation structures of parental stress, general health and anxiety

A partial least square regression (PLSR) was performed on the Swedish Parenthood Stress Questionnaire (SPSQ) sum score and subscales on incompetence, role restriction, social isolation, spouse relationship and health problems, using 42 items from the General Health Questionnaire (GHQ) and 20 items from the State Anxiety Inventory (STAI-X1). The dataset contained 227 fathers and 301 mothers of children aged 1.0-6.6 years from a population-based study on parental psychological distress in the general Norwegian population, and all items correlated positively with SPSQ. Subscales on spouse relationship, incompetence, social isolation and role restriction related to items on state anxiety and depression. The SPSQ subscale on health problems related to GHQ items on somatic symptoms and social dysfunction. The STAI-X1 item "not feeling rested" had a particularly important effect on parental stress. Underlying correlation structures between parental stress and items from STAI-X1 and GHQ were explored, but only the SPSQ sum score could be acceptably predicted. PLSR as a statistical methodology was found useful for health and psychometric data.     

Stress at encoding,context at retrieval,and children’s narrative content

Research concerning the relations between stress and children’s memory has been primarily correlational and focused on memory volume and accuracy. In the current study, we experimentally manipulated 7- and 8-year-olds’ and 12- to 14-year-olds’ experienced stress during a to-be-remembered event to examine the effects of stress on the content of their memory. We further manipulated the degree of interviewer support at retrieval to determine whether it moderated the effects of stress at encoding on memory. Children’s age, gender, stress at encoding, and interviewer support all influenced the type of information included in their narrative reports. Most notably, across ages, children who experienced a more stressful event but were questioned in a supportive manner provided the largest ratio of terms representing internal states such as those about cognitions and emotions. Results suggest that how children process past events may be influenced by both the nature of the event itself and the context within which it is recalled.     

To Pass or Not to Pass: A Mathematical Model for Competitive Interactions in Rugby Union

ABSTRACT. Predicting behavior has been a main challenge in human movement science. An important step within the theory of coordination dynamics is to find out the rules that govern human behavior by defining order parameters and control parameters that support mathematical models to predict the behavior of a system. Models to describe human coordination have been focused on interlimb coordination and on interpersonal coordination in affiliative tasks but not on competitive tasks. This article aims to present a formal model with two attractors to describe the interactive behavior on a 2v1 system in rugby union. Interpersonal distance and relative velocity critical values were empirically identified and were included as task constraints that define the attractor landscape. It is shown that using relative velocity as a control parameter the model offers reasonable prediction concerning the decision-making process. The model has the plasticity to adapt to other settings where interpersonal distances and relative velocities amongst system components act as significant task constraints.
