During the 2010s, a radical transformation took place in the Spanish philosophical landscape: most philosophy journals started releasing their papers for free under a creative commons licence. Thanks to open access publication, Spanish philosophy has a bigger audience today than never before. Drawing on the authors’ experience as editors of two of these journals, Theoria and Recerca, this paper discusses what made this transformation possible, its consequences for the assessment of the Spanish philosophical output and, finally, how to strengthen Spanish (...) philosophy journals to confront the forthcoming challenges in open access publishing.

It has generally been assumed that rapid visual search is based on simple features and that spatial relations between features are irrelevant for this task. Seven experiments involving search for line drawings contradict this assumption; a major determinant of search is the presence of line junctions. Arrow- and Y-junctions were detected rapidly in isolation and when they were embedded in drawings of rectangular polyhedra. Search for T-junctions was considerably slower. Drawings containing T-junctions often gave rise to very slow search even (...) when distinguishing arrow- or Y-junctions were present. This sensitivity to line relations suggests that preattentive processes can extract 3-dimensional orientation from line drawings. A computational model is outlined for how this may be accomplished in early human vision. (shrink)

La autonomía constituye uno de los pilares básicos de un sistema político como el democrático que se asocia a la capacidad de toma de decisiones de la ciudadanía como su núcleo moral principal. Los descubrimientos en el ámbito de las neurociencias y su aplicación al campo del marketing y a la comunicación política despiertan hoy en día las sospechas por la posible capacidad de activar el "botón del voto" de los electores. Este artículo tiene como objetivo adentrarse en el estudio (...) de los principales trabajos desarrollados sobre el neuromarketing político y la neuropolítica. La finalidad de esta propuesta consiste en presentar los debates éticos que irrumpen con el neuromarketing político. Autonomy is one of the basic pillars of a political system like democracy, which is associated with citizens’ decision-making capacity as its main moral core. Discoveries in the neurosciences domain and their application to the marketing and political communication field now arouse suspicions about the possible capacity of activating voter’s "voting button". The objective of this article is to examine the main works on political neuromarketing and neuropolitics. The purpose of this proposal consists in presenting the specific ethical debates that emerge around political neuromarketing. (shrink)

Previous theories of early vision have assumed that visual search is based on simple two-dimensional aspects of an image, such as the orientation of edges and lines. It is shown here that search can also be based on three-dimensional orientation of objects in the corresponding scene, provided that these objects are simple convex blocks. Direct comparison shows that image-based and scene-based orientation are similar in their ability to facilitate search. These findings support the hypothesis that scene-based properties are represented at (...) preattentive levels in early vision. (shrink)

The task of visual search is to determine as rapidly as possible whether a target item is present or absent in a display. Rapidly detected items are thought to contain features that correspond to primitive elements in the human visual system. In previous theories, it has been assumed that visual search is based on simple two-dimensional features in the image. However, visual search also has access to another level of representation, one that describes properties in the corresponding three-dimensional scene. Among (...) these properties are three dimensionality and the direction of lighting, but not viewing direction. These findings imply that the parallel processes of early vision are much more sophisticated than previously assumed. (shrink)

Experiments are presented showing that visual search for Mueller-Lyer (ML) stimuli is based on complete configurations, rather than component segments. Segments easily detected in isolation were difficult to detect when embedded in a configuration, indicating preemption by low-level groups. This preemption—which caused stimulus components to become inaccessible to rapid search—was an all-or-nothing effect, and so could serve as a powerful test of grouping. It is shown that these effects are unlikely to be due to blurring by simple spatial filters at (...) early visual levels. It is proposed instead that they are due to more sophisticated processes that rapidly bind contour fragments into spatially-extended assemblies. These results support the view that rapid visual search cannot access the primitives formed at the earliest stages of visual processing; rather, it can access only higher-level, more ecologically-relevant structures.

We show that early vision can use monocular cues to rapidly complete partially-occluded objects. Visual search for easily detected fragments becomes difficult when the completed shape is similar to others in the display; conversely, search for fragments that are difficult to detect becomes easy when the completed shape is distinctive. Results indicate that completion occurs via the occlusion-triggered removal of occlusion edges and linking of associated regions. We fail to find evidence for a visible filling-in of contours or surfaces, but (...) do find evidence for a "functional" filling-in that prevents the constituent fragments from being rapidly accessed. As such, it is only the completed structures—and not the fragments themselves—that serve as the basis for rapid recognition. (shrink)

Advances in neuroscience implicate reentrant signaling as the predominant form of communication between brain areas. This principle was used in a series of masking experiments that defy explanation by feed-forward theories. The masking occurs when a brief display of target plus mask is continued with the mask alone. Two masking processes were found: an early process affected by physical factors such as adapting luminance and a later process affected by attentional factors such as set size. This later process is called (...) masking by object substitution, because it occurs whenever there is a mismatch between the reentrant visual representation and the ongoing lower level activity. Iterative reentrant processing was formalized in a computational model that provides an excellent fit to the data. The model provides a more comprehensive account of all forms of visual masking than do the long-held feed-forward views based on inhibitory contour interactions. (shrink)

A modified visual search task demonstrates that humans are very good at resuming a search after it has been momentarily interrupted. This is shown by exceptionally rapid response time to a display that reappears after a brief interruption, even when an entirely different visual display is seen during the interruption and two different visual searches are performed simultaneously. This rapid resumption depends on the stability of the visual scene and is not due to display or response anticipations. These results are (...) consistent with the existence of an iterative hypothesis-testing mechanism that compares information stored in short-term memory (the perceptual hypothesis) with information about the display (the sensory pattern). In this view, rapid resumption occurs because a hypothesis based on a previous glance of the scene can be tested very rapidly in a subsequent glance, given that the initial hypothesis-generation step has already been performed.

«Hva er det vi egentlig mener når vi sier, mennesket er dødelig?» spør Woody Allen i boken The Insanity Defence. Han legger til: «Det er åpenbart ikke et kompliment.»1 Jeg tror Woody tar feil her. Vår dødelighet er et kompliment – eller i det minste av det gode – siden livet uten døden ville være katastrofalt. Udødelige liv fører til dyp kjedsomhet, eksistensiell angst og en radikal form for verdinihilistisk tilværelse. Grunnen er at udødeligheten gjør at vi en gang i (...) fremtiden må konfronteres med de radikalt livsfiendtlige stadiene av universets historie. Jeg argumenterer for at dette er en skjebne langt verre enn døden. Konklusjonen blir derfor, med et nikk til Voltaire, at om døden ikke hadde eksistert, hadde vi vært nødt til å finne den opp. (shrink)

Språket vårt utgjør en stor del av vår identitet. Det er et redskap for kommunikasjon med andre mennesker, men også med oss selv. Vi uttrykker oss gjennom språket, og vi tenker ved hjelp av språket. Men hva er egentlig språk? Gjennom å ta for meg to vesensforskjellige tilnærminger til dette spørsmålet ønsker jeg å vise at det synet vi har på språk, har stor filosofiske betydning. Dette er fordi et språksyn nødvendigvis vil få konsekvenser for hvordan vi tenker om beslektede (...) filosofiske spørsmål, som blant annet: -/- – Hva er forholdet mellom språk og verden? -/- – Hva er sannhet? -/- – Hvordan får vi kunnskap om verden? -/- – Hva gjør vi når vi bruker språk? -/- – Hva er vår rolle som språkbrukere? -/- – Hvordan lærer vi språk? -/- Det er to ting som er viktig å avklare om vinklingen av denne artikkelen: Det første er at når jeg her velger å skissere to ulike filosofiske syn på språk, er det for å belyse de spørsmålene jeg har satt opp ovenfor, snarere enn å angripe eller fremme konkrete filosofiske teorier. Det andre er at når jeg her skriver om forholdet mellom språk og verden, og vår rolle som språkbrukere, vil jeg ta for gitt at dette omfatter alle naturlige språksystemer. Poengene mine er derfor ment å ha overføringsverdi til tegnspråk i sin alminnelighet, og selvfølgelig også til norsk tegnspråk. Dette innebærer at det jeg sier om ord, like gjerne kan sies om tegn. Målet med artikkelen er først og fremst å vise at språket må forstås som et gjennomgripende erkjennelsesmiddel i vårt møte med verden. (shrink)

God speaks. Hearing God. Two phrases of two words each are perhaps the most critical, misunderstood and even abused words in the existence of the Church and in particular for evangelicals. ‘I think God said’ and ‘I think God is saying’ are the most sagacious, precise, truthful and appropriate manner of responding to the conviction that God speaks and for shared engaging enriched discourse on what God says to ensure He is heard. The Bible must never be seen and interpreted (...) only as a handbook, instruction or rules book of propositional information, doctrine and description. Rather it is an astonishing and amazing book full of God’s wisdom for all people in all their situatedness. Peter Enns pointed out that the Bible must be seen as a source of godly wisdom to be explored, pondered, deliberated, and put into action. It is not a book about a God ‘mainly interested in whether we’ve read and understood the fine print; if not, God has no recourse but to punish us. Rather, I would beseech all Christians of all epochs to see it as a book full of wisdom relevant for each situatedness and ‘allows us to see God as a good parent, full of grace, love, and patience - the very character traits we value in earthly parents and that the people of God are to exemplify. Wisdom heals us to see God as God is.’ If there is any merit in this essay and conclusion of mine, then perhaps God can strike a straight blow with a very crooked stick. (shrink)
