Wherein lies the debate? Concerning whether God is a person

International Journal for Philosophy of Religion - Within contemporary philosophy of religion there are three main ways in which God is conceptualised in relation to personhood: The first two of...     

Mitigation system threat partially mediates the effects of right‐wing ideologies on climate change beliefs

Research consistently shows that right‐wing ideological adherents are more likely to deny climate change. However, less is known about how right‐wing ideological subtypes are uniquely related to climate change denial, as well as what explains these relationships. This study examines whether threat to the socioeconomic system in the form of climate change mitigation policies, referred to as Climate Change Mitigation Threat (CCMT), mediates the relationships between Right‐Wing Authoritarianism (RWA) and Social Dominance Orientation (SDO) subtypes and four forms of climate change denial (existence denial, human cause denial, impact denial and climate science denial). U.S. participants (N = 334; M_age = 34.70, SD = 5.98) were recruited via Amazon MTurk. When shared variance in the predictors was accounted for, we found that: (a) Conventionalism (RWA‐C) positively predicted all forms of climate change denial; (b) Dominance (SDO‐D) positively predicted existence denial; (c) Anti‐Egalitarianism (SDO‐E) positively predicted both human cause and impact denial; and (d) Aggression (RWA‐A) negatively predicted existence denial. All significant direct relationships were partially mediated by CCMT, except for the direct paths between SDO‐D and existence denial, and RWA‐A and existence denial. These findings suggest that right‐wing adherents who conform to societal norms and prefer unequal social systems may deny climate change partly due to a perception that mitigation strategies proposed to combat climate change threaten the existing socioeconomic system.     

A paradox for some theories of welfare

Sometimes people desire that their lives go badly, take pleasure in their lives going badly, or believe that their lives are going badly. As a result, some popular theories of welfare are paradoxical. I show that no attempt to defend those theories from the paradox fully succeeds.     

EMOTLAB: Software for studying emotional signaling in economic bargaining games

EMOTLAB software creates a virtual social environment in which individuals interact via computer with a virtual interaction partner in a series of economic bargaining games. The virtual partner appears on the participant's computer screen as a digital image (e.g., video or picture file) during each trial. A key feature of EMOTLAB software is its ability to control both the strategic behavior and the emotion signaling behavior (e.g., anger vs. embarrassment) of the virtual interaction partner. By simply editing a series of text files that control the subroutines governing the different features of the experiment (payoff structure, number of trials, etc.), EMOTLAB can generate an essentially infinite number of different social bargaining situations in which participants earn monetary payoffs contingent upon their decisions. This paper provides an overview of this software and how one can edit various subroutines to generate a typical experimental session in which research participants encounter a virtual interaction partner who displays different emotional signals.     

A role for eyebrows in regulating the visibility of eye gaze direction

The human eye is unique amongst those of primates in having white sclera against which the dark iris is clearly visible. This high-contrast structure makes the gaze direction of a human potentially easily perceptible to others. For a social creature such as a human, the ability to perceive the direction of another's gaze may be very useful, since gaze usually signals attention. We report data showing that the accuracy of gaze deviation detection is independent of viewing distance up to a certain critical distance, beyond which it collapses. This is, of itself, surprising since most visual tasks are performed better at closer viewing distances. Our data also show that the critical distance, but not accuracy, is affected by the position of the eyebrows so that lowering the eyebrows reduces the critical distance. These findings show that mechanisms exist by which humans could expand or restrict the availability of their gaze direction to others. A way to regulate the availability of the gaze direction signal could be an advantage. We show that an interpretation of eyebrow function in these terms provides a novel explanation for several well-known eyebrow actions, including the eyebrow flash.     

Attentional functions of cortical cholinergic inputs: what does it mean for learning and memory?

The hypothesis that cortical cholinergic inputs mediate attentional functions and capacities has been extensively substantiated by experiments assessing the attentional effects of specific cholinotoxic lesions of cortical cholinergic inputs, attentional performance-associated cortical acetylcholine release, and the effects of pharmacological manipulations of the excitability of basal forebrain corticopetal cholinergic projections on attentional performance. At the same time, numerous animal experiments have suggested that the integrity of cortical cholinergic inputs is not necessary for learning and memory, and a dissociation between the role of the cortical cholinergic input system in attentional functions and in learning and memory has been proposed. We speculate that this dissociation is due, at least in part, to the use of standard animal behavioral tests for the assessment of learning and memory which do not sufficiently tax defined attentional functions. Attentional processes and the allocation of attentional capacities would be expected to influence the efficacy of the acquisition and recall of declarative information and therefore, persistent abnormalities in the regulation of the cortical cholinergic input system may yield escalating impairments in learning and memory. Furthermore, the cognitive effects of loss of cortical cholinergic inputs are augmented by the disruption of the top-down regulation of attentional functions that normally acts to optimize information processing in posterior cortical areas. Because cortical cholinergic inputs play an integral role in the mediation of attentional processing, the activity of cortical cholinergic inputs is hypothesized to also determine the efficacy of learning and memory.     

Autism and the experience of a perceptual object

Sewards and Sewards (2002) argue that while computations necessary for object recognition occur throughout the ventral visual stream, object recognition awareness involves the anterior temporal lobe and the medial orbital prefrontal cortex. The present paper suggests, however, that the medial orbital prefrontal cortex has a unique contribution, namely that of producing a basic experience of a perceptual object. It is further argued that the mechanisms that produce this experience also result in making the object more important than its subparts and features. Finally, it is argued that a reduction in this importance may account for some perceptual difficulties in high-functioning autism. This view is consistent with evidence for early selective abnormalities in other systems involving the medial prefrontal cortex in autism.     

Fusions and Ordinary Physical Objects

In “Tropes and Ordinary Physical Objects”, Kris McDaniel argues that ordinary physical objects are fusions of monadic and polyadic tropes. McDaniel calls his view “TOPO”—for “Theory of Ordinary Physical Objects”. He argues that we should accept TOPO because of the philosophical work that it allows us to do. Among other things, TOPO is supposed to allow endurantists to reply to Mark Heller’s argument for perdurantism. But, we argue in this paper, TOPO does not help endurantists do that; indeed, we argue that anyone who accepts TOPO should reject endurantism.     

Positive Mood and Future-Oriented Self-Evaluation

When individuals think about their future, feedback on their strengths and weaknesses may often serve as a useful source of information. Three studies investigated the influence of positive and neutral moods on feedback seeking. In Studies 1 and 2, positive mood increased interest in feedback about weaknesses when this information was useful for self-assessment and self-improvement. But when the feedback was not useful for these superordinate, long-term goals then positive mood directed participants’ interest to strength-focused feedback, thereby serving short-term, affective concerns (e.g., feeling good about oneself). Study 3 directly manipulated self-evaluative goals. When a learning goal was activated, positive mood increased interest in weaknesses-focused feedback, but when an affective goal was activated, positive mood increased interest in strength-focused feedback. These results support our hypothesis that positive mood attunes individuals to the relationships of goals and means, thus promoting actions that serve primary goals.
