Increasing behavioural evidence suggests that expert video game players (VGPs) show enhanced visual attention and visuospatial abilities, but what underlies these enhancements remains unclear. We administered the Poffenberger paradigm with concurrent electroencephalogram (EEG) recording to assess occipital N1 latencies and interhemispheric transfer time (IHTT) in expert VGPs. Participants comprised 15 right-handed male expert VGPs and 16 non-VGP controls matched for age, handedness, IQ and years of education. Expert VGPs began playing before age 10, had a minimum 8 years experience, and (...) maintained playtime of at least 20 hours per week over the last 6 months. Non-VGPs had little-to-no game play experience (maximum 1.5 years). Participants responded to checkerboard stimuli presented to the left and right visual fields while 128-channel EEG was recorded. Expert VGPs responded significantly more quickly than non-VGPs. Expert VGPs also had significantly earlier occipital N1s in direct visual pathways (the hemisphere contralateral to the visual field in which the stimulus was presented). IHTT was calculated by comparing the latencies of occipital N1 components between hemispheres. No significant between-group differences in electrophysiological estimates of IHTT were found. Shorter N1 latencies may enable expert VGPs to discriminate attended visual stimuli significantly earlier than non-VGPs and contribute to faster responding in visual tasks. As successful video-game play requires precise, time pressured, bimanual motor movements in response to complex visual stimuli, which in this sample began during early childhood, these differences may reflect the experience and training involved during the development of video-game expertise, but training studies are needed to test this prediction.

In order to improve our understanding of the components that reflect functionally important processes during reward anticipation and consumption, we used principle components analyses (PCA) to separate and quantify averaged ERP data obtained from each stage of a modified monetary incentive delay (MID) task. Although a small number of recent ERP studies have reported that reward and loss cues potentiate ERPs during anticipation, action preparation, and consummatory stages of reward processing, these findings are inconsistent due to temporal and spatial overlap (...) between the relevant electrophysiological components. Our results show three components following cue presentation are sensitive to incentive cues (N1, P3a, P3b). In contrast to previous research, reward‐related enhancement occurred only in the P3b, with earlier components more sensitive to break‐even and loss cues. During feedback anticipation, we observed a lateralized centroparietal negativity that was sensitive to response hand but not cue type. We also show that use of PCA on ERPs reflecting reward consumption successfully separates the reward positivity from the independently modulated feedback‐P3. Last, we observe for the first time a new reward consumption component: a late negativity distributed over the left frontal pole. This component appears to be sensitive to response hand, especially in the context of monetary gain. These results illustrate that the time course and sensitivities of electrophysiological activity that follows incentive cues do not follow a simple heuristic in which reward incentive cues produce enhanced activity at all stages and substages.

Suppose that two competing norms, N1 and N2, can be identified such that a given person’s response can be interpreted as correct according to N1 but incorrect according to N2. Which of these two norms, if any, should one use to interpret such a response? In this paper we seek to address this fundamental problem by studying individual variation in the interpretation of conditionals by establishing individual profiles of the participants based on their case judgments and reflective attitudes. To investigate (...) the participants’ reflective attitudes we introduce a new experimental paradigm called the Scorekeeping Task. As a case study, we identify the participants who follow the Suppositional Theory of conditionals (N1) versus Inferentialism (N2) and investigate to what extent internally consistent competence models can be reconstructed for the participants on this basis. After extensive empirical investigations, an apparent reasoning error with and-to-if inferences was found in one of these two groups. The implications of this case study for debates on the proper role of normative considerations in psychology are discussed. (shrink)

Les noms sous-spécifiés, qui peuvent apparaitre dans une construction spécificationnelle, de la forme Leur ambition a été d’innover, sont par ailleurs souvent des prédicats régissant des arguments, dans une phrase élémentaire de la forme Ils ont eu l’ambition d’innover, où Nss est le prédicat accompagné d’un verbe support et de ses arguments N0 et N1. Nous avons étudié des noms entrant à la fois dans les deux constructions et avec le même sens, et trouvé trois cas de figure. Avec des (...) noms tels que ambition, et ont presque le même sens. Dans d’autres entrées, telles que souvenir et preuve, les deux constructions ne sont pas équivalentes : l’attribut phrastique de est absent de, tandis que l’argument N1 de peut apparaitre comme complément de nom du Nss sujet dans, et spécifie souvent le thème du propos contenu dans l’attribut phrastique de. Enfin, d’autres noms tels que embarras ne sont pas des Nss typiques car l’attribut phrastique de y joue un rôle causal ; il n’a pas le même contenu que N1. Ainsi, dans les types souvenir/preuve et embarras, est à analyser comme une combinaison de plusieurs phrases élémentaires. (shrink)

Edward Nieznanski developed in 2007 and 2008 two different systems in formal logic which deal with the problem of evil. Particularly, his aim is to refute a version of the logical problem of evil associated with a form of religious determinism. In this paper, we revisit his first system to give a more suitable form to it, reformulating it in first-order modal logic. The new resulting system, called N1, has much of the original basic structure, and many axioms, definitions, and (...) theorems still remain; however, some new results are obtained. If the conclusions attained are correct and true, then N1 solves the problem of evil through the refutation of a version of religious determinism, showing that the attributes of God in Classical Theism, namely, those of omniscience, omnipotence, infallibility, and omnibenevolence, when adequately formalized, are consistent with the existence of evil in the world. We consider that N1 is a good example of how formal systems can be applied in solving interesting philosophical issues, particularly in Philosophy of Religion and Analytic Theology, establishing bridges between such disciplines.

Objectives: Inferior oblique muscle overaction (IOOA) is a common ocular motility disorder. Ocular Vestibular Evoked Myogenic Potentials (oVEMP) are tests that evaluate the reflex pathway between the utricular macula and the inferior oblique muscle to detect vestibular diseases. Our study is of great importance as it is the first study in the literature to evaluate the effect of inferior oblique muscle overaction on oVEMP parameters. -/- Methods: Thirty-five patients with unilateral inferior oblique muscle overaction (IOOA group) and 18 healthy volunteers (...) without any neurological or vestibulocochlear disease were included in this study. All patients and healthy volunteers were evaluated with oVEMP. -/- Results: No statistically significant difference was found between the n1 latency, p1 latency, n1-p1 latency measurement values of the participants included in the study (p>0,05). A statistically significant difference was found between the n1-p1 amplitude measurement values of the participants in patient groups (non-squint eyes, squint eyes) and control groups (p-value was 0.038). -/- Conclusion: In IOOA patients, vestibulo-ocular reflex pathway may be affected, vestibular symptoms may develop thus o-VEMP responses may be affected. A careful anamnesis should be taken in IOOA patients, and it should be kept in mind that n1-p1 amplitudes and asymmetries may be significantly higher when o-VEMP is performed. (shrink)

We investigate the morphosyntax of qualitative binominal constructions (QBCs) in a Southern Italo-Romance language from the Apulian town of San Marco in Lamis. QBCs are complex noun phrases like ‘a jewelN1 of a villageN2’, appearing here prepositionally (with the preposition də, ‘of’, allowing definites, indefinites, and demonstratives) and non-prepositionally (only allowing definites with definite articles and not proper names). We propose that in the latter, a categorial match in the determiner layer, which we call ‘match D’, relates N1 and N2. (...) N1 is embedded as a noun, allowing for: 1) the recursive DP strategy of non-prepositional genitives, and 2) the extension of this mechanism to QBCs. This leads to the impossibility of syntactic extraction, which we connect to the concept of phase. With non-denominal N1s, N1’s article is treated as a head-agreeing adjectival linker, forming a constituent with the modifier but agreeing with the head. A phrase is interpreted as a QBC if N1 and N2 share the same number features and if the features of N1 do not allow for it to be interpreted as the possessum of N2 . We also discuss external agreement with the construction, presenting data supporting the relevance of the [+HUMAN] feature for agreement relations. (forthcoming, Italian Journal of Linguistics).

Groups have committed historical wrongs (e.g., genocide, slavery). We investigated why people blame current groups who were not involved in the original historical wrong for the actions of their predecessors who committed these wrongs and are no longer alive. Current models of individual and group blame overlook the dimension of time and therefore have difficulty explaining this phenomenon using their existing criteria like causality, intentionality, or preventability. We hypothesized that factors that help psychologically bridge the past and present, like perceiving (...) higher (a) connectedness between past and present perpetrator groups, (b) continued privilege of perpetrator groups, (c) continued harm of victim groups, and (d) unfulfilled forward obligations of perpetrator groups would facilitate higher blame judgments against current groups for the past. In two repeated-measures surveys using real events (N1 = 518, N2 = 495) and two conjoint experiments using hypothetical events (N3 = 598, N4 = 605), we find correlational and causal evidence for our hypotheses. These factors link present groups to their past and cause more historical blame and support for compensation policies. This work brings the dimension of time into theories of blame, uncovers overlooked criteria for blame judgments, and questions the assumptions of existing blame models. Additionally, it helps us understand the psychological processes undergirding intergroup relations and historical narratives mired in historical conflict. Our work provides psychological insight into the debates on intergenerational justice by suggesting methods people can use to ameliorate the psychological legacies of historical wrongs and atrocities.

Subjective perception of sleep is not necessarily consistent with electroencephalography (EEG) indications of sleep. The mismatch between subjective reports and objective measures is often referred to as “sleep state misperception.” Previous studies evince that this mismatch is found in both patients with insomnia and in normal sleepers, but the neurophysiological mechanism remains unclear. The aim of the study is to explore the neurophysiological basis of this mechanism, from the perspective of both EEG power and functional magnetic resonance imaging (fMRI) fluctuations. (...) Thirty-six healthy young adults participated in the study. Simultaneous EEG and fMRI recordings were conducted while the participants were trying to fall asleep in an MRI scanner at approximately 9:00 pm. They were awakened after achieving stable N1 or N2 sleep, or after 90 min without falling into stable sleep. Next they were asked to recall their conscious experiences from the moment immediately prior to awakening. Sixty-one instances of scheduled awakenings were collected: 21 of these after having achieved stable stage N2 sleep; 12, during stage N1 sleep; and, 20 during the waking state. Relative to those awakenings without subjective–objective discrepancy (n = 27), these awakenings with discrepancy (n = 14) were associated with lower θ power, as well as higher α, β, and γ power. Moreover, we found that participants who exhibited the discrepancy, compared with those who did not, evinced a higher amplitude of low-frequency fluctuation levels in the prefrontal cortex. These results lend support to the conjecture that the subjective–objective discrepancy is associated with central nervous system hyperarousal. (shrink)

Edward Nieznański developed two logical systems in order to deal with a version of the problem of evil associated with two formulations of religious determinism. The aim of this research was to revisit these systems, providing them with a more appropriate formalization. The new resulting systems, namely, N1 and N2, were reformulated in first-order modal logic; they retain much of their original basic structures, but some additional results were obtained. Furthermore, our research found that an underlying minimal set of axioms (...) is enough to settle the questions proposed. Thus, we developed a minimal system, called N3, that solves the same issues tackled by N1 and N2, but with less assumptions than these systems. All of the systems developed here are proposed as solutions to the logical problem of evil through the refutation of two versions of religious determinism, showing that the attributes of God in Classical Theism, namely, those of omniscience, omnipotence, infallibility, and omnibenevolence, when formalized, are consistent with the existence of evil, providing one more response to this traditional issue.
