The four faces of omission

In this paper, the ontological, terminological, epistemological, and ethical aspects of omission are considered in a coherent and balanced framework, based on the idea that there are omissions which are actions and omissions which are non-actions. In particular, we suggest that the approach to causation which best deals with omission is Mackie's INUS conditional proposal. We argue that omissions are determined partly by the ontological conditional structure of reality, and partly by the interests, beliefs, and values of observers. The final upshot is that moral judgments involved in cases of omissions cannot be grounded on, but are the ground for judgments about what INUS conditions count as omissions.     

New Strategies in the Assessment of Psychological Factors Affecting Medical Conditions

In this article, we examine research that may lead to a better assessment of psychological factors affecting medical conditions. We performed a review of the psychosomatic literature using both Medline and manual searches. We selected papers that were judged to be relevant to new strategies of assessment, with particular reference to the use of the Diagnostic Criteria for Psychosomatic Research. We assessed 8 areas concerned with the assessment of psychological factors in the setting of medical disease: hypochondriasis, disease phobia, persistent somatization, conversion symptoms, illness denial, demoralization, irritable mood, and Type A behavior. A new subclassification of the Diagnostic and Statistical Manual of Mental Disorders (5th ed. [DSM-V]; not yet published) category of psychological factors affecting physical conditions appears to be feasible and may provide the clinician with better tools for identifying psychological distress.     

When REBT Goes Difficult: Applying ABC-DEF to Personality Disorders

ABC-DEF framework is at the core of rational emotive behavior therapy. It is a highly flexible framework and has proven to be applicable to many emotional disorders. We cannot take for granted, however, that this framework can be used successfully with all clients, particularly with those suffering from severe disorders or personality disorders. In fact, the difficulties of these clients in recognizing, naming and reflecting upon states of mind, their dysregulated emotions and self-defeating behavior, and their difficulty in establishing a strong working alliance with a therapist may hamper the correct implementation of the ABC-DEF framework and the disputing of their irrational beliefs. This paper aims to describe in detail the challenges that clients with personality disorders may pose during treatment and offer possible technical suggestions, derived from either REBT or non-REBT literature, that can help REBT and CBT practitioners adapting their interventions to resistant clients.     

How different is a 3D‐printed replica from a conspecific in the eyes of a zebrafish?

Robotics is emerging as a promising tool for aiding research on animal behavior. The possibility of generating customizable, controllable, and standardized robotic stimuli has been demonstrated through a number of behavioral assays, involving vertebrates and invertebrates. However, the specific appraisal of the nature of robotic stimuli is currently lacking. Here, we attempt to evaluate this aspect in zebrafish, through a within‐subject design in which experimental subjects are faced with three experimental conditions. In the first test, we investigated sociability by measuring zebrafish response to a conspecific separated by a one‐way glass. In the second test, we studied zebrafish behavior in response to a 3D‐printed zebrafish replica actuated along realistic trajectories through a novel four‐degree‐of‐freedom robotic platform. Last, we investigated fear responses in a shelter‐seeking test. In agreement with our expectations, zebrafish exhibited an equivalent preference for live and robotic stimuli, and the degree of preference for the robotic replica correlated negatively with the individual propensity to seek shelter. The equivalent preference for the replica and conspecific suggests that the appraisal of the target stimuli is analogous. The preliminary evidence of a correlation between behavioral responses across tests points to the readability of robotics‐based approaches to investigate interindividual differences.     

When affordances climb into your mind: Advantages of motor simulation in a memory task performed by novice and expert rock climbers

Does the sight of multiple climbing holds laid along a path activate a motor simulation of climbing that path? One way of testing whether multiple affordances and their displacement influence the formation of a motor simulation is to study acquired motor skills. We used a behavioral task in which expert and novice rock climbers were shown three routes: an easy route, a route impossible to climb but perceptually salient, and a difficult route. After a distraction task, they were then given a recall test in which they had to write down the sequence of holds composing each route. We found no difference between experts and novices on the easy and impossible routes, whereas on the difficult route, the performance of experts was better than that of novices. This suggests that seeing a climbing wall activates a motor, embodied simulation, which relies not on perceptual salience, but on motor competence. More importantly, our results show that the capability to form this simulation is modulated by individuals’ motor repertoire and expertise, and that this strongly impacts recall.     

What is the Reason for This Rule? An Inferential Account of the <Emphasis Type="Italic">Ratio Legis</Emphasis>

Several legal arguments use the notion of ratio legis in order to sustain a normative conclusion, in particular the argument from analogy and some forms of teleological argumentation. However, determining the ratio is often a difficult and controversial task. In this paper we look firstly at the speech acts typically performed by legal practitioners in order to determine the ratio and, secondly, we take into account the argumentative commitments they undertake in so doing and the argumentative constraints put on them. This will lead us to distinguish different uses of the notion of ratio legis and to ask on what conditions each of them is justified.     

Connected guys: Endorsement of masculine honour predicts more frequent contact with members of criminal organisations

Italian criminal organisations (COs) engage in contact with community members to assert their control over local populations in Southern Italy. According to intracultural appropriation theory, COs’ presence in these regions is legitimised by values of masculinity and honour. Here, we test the role of these values in drawing people closer to COs, facilitating more frequent contact with COs’ members. Study 1 (N_T1 = 176, N_T2 = 170) used a two-wave longitudinal design demonstrating that endorsement of masculine honour predicts more frequent contact with COs after five months. In contrast, results revealed no longitudinal effect of contact frequency on masculine honour endorsement. Using a cross-sectional design, Study 2 (N = 314) extended these results by revealing an indirect effect of masculine honour on the tendency to see COs as embodying honour and respect (romanticisation), through more frequent contact with COs’ members. Limitations, directions for future research and implications of these results are discussed.     

Human gaze behaviour during action execution and observation

Gaze shifts and fixations appear to be proactive in both action execution and observation. We investigated a dependency of anticipatory gaze behaviour by using a block stacking task. Blocks were rectangles depicted on a computer screen and the stacking movements were controlled via computer mouse. Subjects either had to execute the task or had to observe it made by the experimenter, or by the computer. The dependency of gaze behaviour on the visibility of a virtual effector, the visibility of the actor, and the nature of the actor was tested by measuring eye movements. Anticipatory eye movements were predominant when the subjects themselves executed the task. During action observation, gaze behaviour did neither depend on the visibility nor depend on the nature of the actor. However, big variability was found between the subjects suggesting the use of two different strategies in action observation: some subjects were mainly tracking the blocks during stacking movements; others were strongly anticipating. We suggest that gaze behaviour during action observation is not predetermined by rigid neural circuitry, but strongly depends on the context. The possibility to explain the causal mechanism, as well as the ownership of the action may be crucial preconditions for anticipatory gaze behaviour.
