Dogs (Canis lupus familiaris) are susceptible to the Kanizsa’s triangle illusion

Animal Cognition - The ability to complete partially missing contours is widespread across the animal kingdom, but whether this extends to dogs is still unknown. To address this gap in knowledge,...     

Understanding and explanation. Paul Ricœur and human geography

Continental Philosophy Review - The aim of my paper is to put Ricœur’s philosophy in dialogue with human geography. There are at least two good reasons to do so. The first concerns the...     

Hegel,the Trinity,and the ‘I’

The main goal of this paper is to argue the relevance of Hegel’s notion of the Trinity with respect to two aspects of Hegel’s idealism: the overcoming of subjectivism and his conception of the ‘I’. I contend that these two aspects are interconnected and that the Trinity is important to Hegel’s strategy for addressing these questions. I first address the problem of subjectivism by considering Hegel’s thought against the background of modern philosophy. I argue that the recognitive structure of Hegel’s idealism led him to give the Trinity a decisive role in his philosophical account. Next, I discuss the Trinity by analysing the three divine persons. This analysis paves the way for the conclusion, where I argue that the Trinity represents a model for re-thinking the ‘I’ in a way that overcomes a ‘naïve realist’ and a ‘subjective’ account of the self. I suggest that Hegel’s absolute idealism can be conceived as an approach to the ‘I’ that considers the role of acts of mutual recognition for the genesis of self-conscious thought, and that the Trinity is the Darstellung of the relational and recognitive structure of the ‘I’.     

“The Postilion’s Horn Sounds”: A Complementarity Approach to the Phenomenology of Sound-Consciousness?

In the phenomenology of the consciousness of internal time, Edmund Husserl has frequent recourse to sound and melody as illustrations of the processes that give rise to immanent temporal objects. In Husserl’s analysis, there is a philosophically pregnant tension between the geometrical diagrams representing multiple dimensions of immanent time and his intuition that time-points might be no more than fictions leading to absurdities. In this paper, I will address this tension in order to motivate a complementarity approach to temporal objects such as sound and melody that might illuminate the phenomenology of sound-consciousness.     

Executive functions,impulsivity, and inhibitory control in adolescents: A structural equation model

Background. Adolescence represents a critical period for brain development, addressed by neurodevelopmental models to frontal, subcortical-limbic, and striatal activation, a pattern associated with rise of impulsivity and deficits in inhibitory control. The present study aimed at studying the association between self-report measures of impulsivity and inhibitory control with executive function in adolescents, employing structural equation modeling. Method. Tests were administered to 434 high school students. Acting without thinking was measured through the Barratt Impulsiveness Scale and the Dickman Impulsivity Inventory, reward sensitivity through the Behavioral Activation System, and sensation seeking through the Zuckerman–Kuhlman–Aluja Personali- ty Questionnaire. Inhibitory control was assessed through the Behavioral Inhibition System. The performance at the Wisconsin Card Sorting Task indicated executive function. Three models were specified using Sample Covariance Matrix, and the estimated parameters using Maximum Likelihood. Results. In the final model, impulsivity and inhibitory control predicted executive function, but sensation seeking did not. The fit of the model to data was excellent. Conclusions. The hypothesis that inhibitory control and impulsivity are predictors of executive function was supported. Our results appear informative of the validity of self-report measures to examine the relation between impulsivity traits rather than others to regulatory function of cognition and behavior.     

On Argumentation Logic and Propositional Logic

This paper studies the relationship between Argumentation Logic (AL), a recently defined logic based on the study of argumentation in AI, and classical Propositional Logic (PL). In particular, it shows that AL and PL are logically equivalent in that they have the same entailment relation from any given classically consistent theory. This equivalence follows from a correspondence between the non-acceptability of (arguments for) sentences in AL and Natural Deduction (ND) proofs of the complement of these sentences. The proof of this equivalence uses a restricted form of ND proofs, where hypotheses in the application of the Reductio of Absurdum inference rule are required to be “relevant” to the absurdity derived in the rule. The paper also discusses how the argumentative re-interpretation of PL could help control the application of ex-falso quodlibet in the presence of inconsistencies.
