66 Buffalo Law Review 123 (2018)This Article offers an unorthodox theory of insanity. According to the traditional theory, insanity is a cognitive or volitional incapacity arising from a mental disease or defect. As an alternative to the traditional theory, some commentators have proposed that insanity is an especially debilitating form of irrationality. Each of these theories faces fair-minded objections. In contrast to these theories, this Article proposes that a person is insane if and because he lacks a sense of agency. The theory of insanity it defends might therefore be called the lost-agency theory.According to the lost-agency theory, a person lacks a sense of agency when he experiences his mind and body moving but doesn’t experience himself as the author or agent of those movements. The title character in the movie Dr. Strangelove suffered from what’s known as alien hand syndrome. People suffering from this syndrome experience the moving hand as their hand but don’t experience themselves as the author or agent of its movements. The lost-agency theory portrays insanity as alien hand syndrome writ large. The insane actor is like someone possessed by an alien self. He’s not in charge of his mind or body when he commits the crime.

Postexperimental Inquiry

Building on Hilgard’s (1965) classic work, the domain of hypnosis has been conceptualised by Barnier, Dienes, and Mitchell (2008) as comprising three levels: (1) classic hypnotic items, (2) responding between and within items, and (3) state and trait. The current experiment investigates sense of agency across each of these three levels. Forty-six high hypnotisable participants completed an ideomotor (arm levitation), a challenge (arm rigidity) and a cognitive (anosmia) item either following a hypnotic induction (hypnosis condition) or without a hypnotic induction (wake condition). In a postexperimental inquiry, participants rated their feelings of control at three time points for each item: during the suggestion, test and cancellation phases. They also completed the Sense of Agency Rating Scale (Polito, Barnier, & Woody, 2013) for each item. Pass rates, control ratings, and agency scores fluctuated across the different types of items and for the three phases of each item; also, control ratings and agency scores often differed across participants who passed versus failed each item. Interestingly, whereas a hypnotic induction influenced the likelihood of passing items, it had no direct effect on agentive experiences. These results suggest that altered sense of agency is not a unidimensional or static quality “switched on” by hypnotic induction, but a dynamic multidimensional construct that varies across items, over time and according to whether individuals pass or fail suggestions.

Intentional Agents

As human adults, we experience ourselves as intentional agents. Here, we address how intentional agency and the corresponding agentive experiences emerge in infancy. When formulating a developmental theory of intentional agency, we encounter a so-called paradox of agency: three plausible theses regarding intentional agency that in combination seem to make it impossible for the developing infant to acquire a sense of agency. By recognizing various types of intentions, we propose a framework in which the paradox can be resolved, allowing infants to bootstrap their way to becoming intentional agents and experiencing a sense of agency.

Action Monitoring

Abstract Current neurocognitive models of motor control postulate that accurate action monitoring is crucial for a normal experience of agency—the ability to attribute the authorship of our actions and their consequences to ourselves. Recent studies demonstrated that action monitoring is impaired in Gilles de la Tourette syndrome, a movement disorder characterized by motor and vocal tics. It follows that Tourette syndrome patients may suffer from a perturbed sense of agency, the hypothesis tested in this study. To this end, we recruited 25 Tourette syndrome patients and 25 matched healthy controls in a case-control behavioural and functional magnetic resonance imaging study. As an implicit index of the sense of agency, we measured the intentional binding phenomenon, i.e., the perceived temporal compression between voluntary movements and their external consequences. We found evidence of an impaired sense of agency in Tourette syndrome patients who, as a group, did not show a significant intentional binding. The more reduced was the individual intentional binding, the more severe were the motor symptoms. Specific differences between the two groups were also observed in terms of brain activation patterns. In the healthy controls group, the magnitude of the intentional binding was associated with the activity of a premotor–parietal–cerebellar network. This relationship was not present in the Tourette syndrome group, suggesting an altered activation of the agency brain network for self-generated acts. We conclude that the less accurate action monitoring described in Tourette syndrome also involves the assessment of the consequences of actions in the outside world. We discuss that this may lead to difficulties in distinguishing external consequences produced by their own actions from the ones caused by others in Tourette syndrome patients.

AbstractIn this paper, we discuss the role of dialogue in two layers; first, in relation to two self-organised communities of science teachers in which we participated and, second, our process of coming together during our PhDs to analyse these communities, a dialogue about the dialogue. Regarding the first layer, there is much to learn from science teachers and science teacher educators when they are organised in sites of learning that can be spaces of hope, beginnings, and becoming, as is illustrated in the case of these two self-organised communities. Regarding the second layer, we discuss the value of dialogue and the possibilities it offers to develop ideas for science education in a way that might be democratising, emancipatory, and offering counter-narratives in a neoliberal Chile. By engaging in this dialogue revisiting the practices of our communities, we gained a sense of agency within the field of science education. However, we realised that we need to move towards a critical view within our communities, and more contextual and transformative science education by translating these sites of hope to our educational praxis today. For us, this relates both to developing a collective view of how to make science education provide pedagogical conditions and experiences for critical and engaged citizenship and thinking how we can act and engage with different settings in solidarity. One way of moving towards this is by developing a political knowledge of our disciplines through a collective scientific conscientisation. Our communities are the departure points to achieve this.

AbstractCircle-line drawing paradigm is used to study bimanual coupling. In the standard paradigm, subjects are asked to draw circles with one hand and lines with the other hand; the influence of the concomitant tasks results in two “elliptical” figures. Here we tested whether proprioceptive information evoked by muscle vibration inducing a proprioceptive illusion (PI) of movement at central level, was able to affect the contralateral hand drawing circles or lines. A multisite 80 Hz-muscle vibration paradigm was used to induce the illusion of circle- and line-drawing on the right hand of 15 healthy participants. During muscle vibration, subjects had to draw a congruent or an incongruent figure with the left hand. The ovalization induced by PI was compared with Real and Motor Imagery conditions, which already have proved to induce bimanual coupling. We showed that the ovalization of a perceived circle over a line drawing during PI was comparable to that observed in Real and Motor Imagery condition. This finding indicates that PI can induce bimanual coupling, and proprioceptive information can influence the motor programs of the contralateral hand.
