Sustained, Multifaceted Improvements in Mental Well-Being Following Psychedelic Experiences in a Prospective Opportunity Sample

In the last 15 years, psychedelic substances, such as LSD and psilocybin, have regained legitimacy in clinical research. In the general population as well as across various psychiatric populations, mental well-being has been found to significantly improve after a psychedelic experience. Mental well-being has large socioeconomic relevance, but it is a complex, multifaceted construct. In this naturalistic observational study, a comprehensive approach was taken to assessing well-being before and after a taking a psychedelic compound to induce a “psychedelic experience.” Fourteen measures of well-being related constructs were included in order to examine the breadth and specificity of change in well-being. This change was then analysed to examine clusters of measures changing together. Survey data was collected from volunteers that intended to take a psychedelic. Four key time points were analysed: 1 week before and 2 weeks, 4 weeks, and 2 years after the experience (N = 654, N = 315, N = 212, and N = 64, respectively). Change on the included measures was found to cluster into three factors which we labelled: 1) “Being well”, 2) “Staying well,” and 3) “Spirituality.” Repeated Measures Multivariate Analysis of Variance revealed all but the spirituality factor to be improved in the weeks following the psychedelic experience. Additional Mixed model analyses revealed selective increases in Being Well and Staying Well (but not Spirituality) that remained statistically significant up to 2 years post-experience, albeit with high attrition rates. Post-hoc examination suggested that attrition was not due to differential acute experiences or mental-health changes in those who dropped out vs. those who did not. These findings suggest that psychedelics can have a broad, robust and sustained positive impact on mental well-being in those that have a prior intention to use a psychedelic compound. Public policy implications are discussed.

Trembling Meaning: Camera Instability and Gilbert Simondon's Transduction in Czech Archival Film

Many experimental found footage films base their meanings and effects on an interaction between the figurative content of the image and its material-technological underpinnings. Can this interaction arise accidentally without artistic appropriation? A recently digitised film by the Czech cinema pioneer Jan Kříženecký, Opening Ceremony of the Čech Bridge (1908), presents such an exercise in accidental aesthetics. At one point, the horizontal and vertical trembling of the cinematograph – obtained from the Lumière brothers – translates into a trembling of the figures on the bridge so precisely that the figurative and material spheres appear to cooperate towards a common aesthetic goal. To account for such phenomena, film theory, found footage filmmaking, and archival practice need to join forces with philosophy. More specifically, Gilbert Simondon's notion of transduction, a process based on the intersection of diverse realities within a domain, allows us to conceptualise the paradoxical interaction between the figurative and material dimensions and the unintentional meanings that arise out of it. Transduction enables the distribution of elements between these heterogeneous spheres while maintaining a certain stability within a system. In the case of archival films in which transduction occurs without prior intention or expectation, transduction can be foregrounded and prolonged. The connection between transduction and the “trembling meaning” of Opening Ceremony, understood within the wider context of camera instability in experimental found footage, will uncover the aesthetic potentialities held by the autonomous creativity of film matter and its interferences with the figurative content.

The influence of prior intention on joint action: an fNIRS-based hyperscanning study

Motor performances of the same action are affected by prior intentions to move unintentionally, cooperatively or competitively. Here, a back-and-forth movement task combined with a motion capture system and functional near-infrared spectroscopy (fNIRS)-based hyperscanning technology was utilized to record both the behavioral and neural data of 18 dyads of participants acting in pairs [joint conditions: no-intention, cooperative (Coop) and competitive (Comp)] or alone (single conditions: self-paced and fast-speed). The results revealed that Coop or Comp intentions in the joint conditions significantly sped up motor performance compared with similar single conditions, e.g. shorter movement times (MTs) in the Coop/Comp condition than the self-paced/fast-speed condition. Hemodynamic response analysis demonstrated that stronger activities for all joint conditions than the single conditions in the premotor and the supplementary motor cortex (Brodmann area 6) were independent of variations of MTs, indicating that they might reflect more complex aspects of action planning rather than simple execution-based processes. The comparisons of joint conditions across distinct prior intentions before acting yielded significant results for both behavioral and neural measures, with the highest activation of the temporo-parietal junction (TPJ) and the shortest MTs in the Comp condition considered to be implications for the top-down influence of prior intentions on joint performance.

Motor Programs as Indicators of Penalty Direction in Soccer

Introduction: Many football games are decided on penalties and usually in championship final games. When seeking to anticipate movements, differences in amplitude can harm players because the informational movement appears to be spread "globally" throughout the action and should be coded at several levels. Thus, it would be interesting to analyze the entire period of the kick, since the player begins his run to approach the ball to recognize the motor patterns used in the kick that identify his direction. Objective: The objective of this study is to identify patterns of behavior in penalty kicks that may indicate the direction of their action / kick and in my moment they appear. Methodology: The sample consisted of 21 subjects hitting a penalty kick, 18 males and 3 females with an average age of 22.18 ± 2.44 years and two goalkeepers with college football experience. The tests consisted of a battery of two penalty kicks for each subject in order to score. The kicks were recorded by a video camera with a front view of the goal goal and the back of the batter. The kick phases were divided into the starting leg position; first step leg; angle of the elbow in relation to the body seen from behind; angle of the elbow in relation to the displacement line seen from above; direction of the tip of the supporting foot and position on the goal where the kick was. Each kick was preceded by a start signal. The data were analyzed from the registration of each variable and the position of the goal in which the ball was kicked, considering it in three sectors: left, right and central. Results: The main results indicated that the variable “Leg of the first step” had 81% of the kicks associated with the direction of the goal; 52.4% of second kicks had repeated the pattern of behavior and 84.6% had repeated the pattern of behavior regardless of the goal position. The variable “Elbow angle in relation to the body seen from behind” had 81.8% repeated behavior pattern regardless of the goal position and the variable “Elbow angle in relation to the displacement line seen from above” had 81% association with the sector of the goal in which the ball was kicked; 52.4% of second kicks had repeated the pattern of behavior and 91.7% had repeated the pattern of behavior regardless of the goal position. Conclusions: The main conclusions indicate that it is possible to relate the kick location with the batter's body information; the start of the race seems to indicate that there is a prior intention of movement programs; the decision of where to hit the penalty appears to be made before contact with the ball and more closely to the placement of the support foot and with this relationship, the size of the goal to be defended by the goalkeeper could be reduced, increasing the possibility of defense.

Planning on a prior intention

Intention plays a central role in coordinating action. It does so, it is commonly thought, by allowing one to plan further actions for the future on the basis of the belief that it will be executed. Doxasticists about intention (Harman, Velleman) conclude from this that accounting for this role of intention requires accepting the thesis that intention involves belief. Conativists about intention (Bratman, Brunero, Mele) reject that conclusion. I argue that Doxasticists are right in calling attention to the existence of a cognitive aspect to intention-based coordination, but that such an aspect is better understood in terms of the attitude of reliance than of belief. I also argue that an appeal to reliance affords Conativists with useful resources for explaining that aspect of intention-based coordination in a way that is compatible with their rejection of the thesis that intention involves belief.

Buddhist Reductionist Action Theory

This essay develops the theory of action presupposed by Buddhist Reductionists. Their account uses the theory of two truths to reconcile the folk theory of human action with the Buddhist claim that there are no agents. The conventional truth has it that persons are substance-causes of actions, and the willings that trigger actions are exercises of a person’s powers in light of their reasons. According to the ultimate truth, there are no persons, only causal series of bundles of tropes. An action is a bodily or mental event in one such series that has the occurrence of a prior intention event as its cause. Facts about causally connected psychophysical elements explain the utility, and thus the conventional truth, of claims about persons as agents. This two-tier account of human agency makes possible a novel approach to making attributions of moral responsibility compatible with psychological determinism.

Antecedents of Moral Pride: the Harder the Action, the Greater the Pride?

The study’s aim was to analyze if some specific types of action generate higher levels of moral pride. Three variables were analyzed: whether the actions involved going against the group majority, whether they involved a personal cost of a different kind and whether they were the result of a prior intention. Participants were 160 adolescents aged between 14 and 16. Sixteen scenarios were designed (two for each combination of the three variables) in which someone needed help. Half of the participants were presented with 8 of these scenarios, and half with the other 8. In each scenario, participants were asked to state what they would feel and do and how much pride they would feel if they helped. Curiously enough, both prosocial behaviors which involved going against the majority, F(1, 140) = 60.36, p = .001, η2 = .301 and those which involved a personal cost of a different kind, F(1, 140) = 10.17, p = .002, η2 = .068 generated less moral pride.
