Nomic Universals and Particular Causal Relations: Which are Basic and Which are Derived?

Armstrong holds that a law of nature is a certain sort of structural universal which, in turn, fixes causal relations between particular states of affairs. His claim that these nomic structural universals explain causal relations commits him to saying that such universals are irreducible, not supervenient upon the particular causal relations they fix. However, Armstrong also wants to avoid Plato’s view that a universal can exist without being instantiated, a view which he regards as incompatible with naturalism. This construal of naturalism forces Armstrong to say that universals are abstractions from a certain class of particulars; they are abstractions from first-order states of affairs, to be more precise. It is here argued that these two tendencies in Armstrong cannot be reconciled: To say that universals are abstractions from first-order states of affairs is not compatible with saying that universals fix causal relations between particulars. Causal relations are themselves states of affairs of a sort, and Armstrong’s claim that a law is a kind of structural universal is best understood as the view that any given law logically supervenes on its corresponding causal relations. The result is an inconsistency, Armstrong having to say that laws do not supervene on particular causal relations while also being committed to the view that they do so supervene. The inconsistency is perhaps best resolved by denying that universals are abstractions from states of affairs.

Which Comes First: Consciousness or Aspartate Receptors?

This paper is a critique of Karl Jansen's hypothesis that near-death and ketamine experiences are caused by blockade of N-methyl-D-aspartate receptors. An assumption that consciousness and its alterations are merely the product of neuronal activity is only one of many possible beliefs about reality. An alternative, which can be verified through one's own direct experience, is that consciousness is always a subject and body is only its object. The objects come and go; consciousness remains.     

Parenting Scale: Which Version Should We Use?

Factor analytic studies of one of the widely used measurements of parental discipline, the Parenting Scale (PS), have yielded ambiguous results. The purpose of this study was to compare various forms of the PS in terms of factor structure and other psychometric properties. The sample consisted of 617 mothers and 430 fathers of 2 to 5-year-olds. Confirmatory factor analysis indicated that shorter structural models provided a better fit compared to the original model; however, none led to an optimal fit. Other psychometric properties such as internal consistency, test-retest reliability, concurrent and predictive validity were slightly higher for the original Laxness and Overreactivity subscales. The findings from this study and previous studies suggest that the inter-item relationship in the scale might be too sensitive to sample characteristics, implying that factor analysis might not be the best way to measure the scale’s validity. Nevertheless, other psychometric properties support the use of the Parenting Scale in the assessment of dysfunctional parenting practices. We recommend using the original Laxness and Overreactivity subscales rather than the later models, especially for research purposes.     

Which Is Better: Simultaneous or Sequential Choice?

The term "diversification bias" refers to the tendency for people to take more variety when choosing several items simultaneously than when choosing them sequentially. In this article, we investigate whether this really is a bias by measuring evaluations of sets chosen simultaneously or sequentially. In Experiment 1 participants made two choices between audio tracks for consecutive consumption. Participants liked low-variety sets most and were more likely to choose high-variety sets in simultaneous choice. In Experiment 2 participants chose between three gambles which varied in the probability of winning and their expected value. Again, simultaneous choices seemed worse than sequential ones: The simultaneous-choice groups took far more low expected value gambles than did sequential-choice subjects and rated their enjoyment as lower. We conclude that simultaneous choice often leads to outcomes that are worse than sequential choice and discuss the circumstances when this is likely to be true.     

Awareness Versus Un-Clinging: Which Matters in Mindfulness?

Awareness and un-clinging have been emphasised in Buddhist discourse as important facets of mindfulness practice for over 2500 years. However, there is a lack of rigorous research examining the relationship between these two elements and their importance to well-being. To evaluate these abstract constructs, the current study adopted multiple assessment modalities; namely, a self-report scale, experience sampling (assessing ‘momentary mindfulness’), and semi-structured interviews (assessing ‘rater-rated mindfulness’). A total of 415 participants completed the questionnaire survey. Among them, 71 participants further took part in the experience sampling procedure and semi-structured interviews. The findings reveal that self-reported awareness was mildly correlated with momentary mindfulness (r = .35) but was not significantly correlated with rater-rated mindfulness. Self-reported un-clinging was moderately correlated with rater-rated mindfulness (r = .53) but was not significantly correlated with momentary mindfulness. Un-clinging, but not awareness, can distinguish meditators from non-meditators. Lastly, based on the Buddha’s mindfulness discourse, a path analysis model illustrates that the effects of un-clinging and awareness on stress reduction are mediated by emotional intelligence and non-attachment. Practical implications and future research designs are discussed.     

Environmental Refugees: What Rights? Which Duties?

It is estimated that there could be 200 million‘environmental refugees’ by the middle of this century. One major environmental cause of population displacement is likely to be global climate change. As the situation is likely to become more pressing, it is vital to consider now the rights of environmental refugees and the duties of the rest of the world. However, this is not an issue that has been addressed in mainstream theories of global justice. This paper considers the potential of two leading liberal theories of international justice to address the particular issues raised by the plight of potential and actual environmental refugees. I argue that neither John Rawls’s ‘Law of Peoples’ approach nor Charles Beitz’s `cosmopolitanism' is capable of providing an adequate account of justice in this context. Beitz’s theory does have some advantages over Rawls’s approach but it fails to take proper account of the attachment that some people have to their own ‘home’.

Which variability?

Drai and Grodzinsky provide a valuable analysis that offers a way of disentangling the effects of Movement and Mood in agrammatic comprehension. However, their mathematical implementation (Beta model) hides theoretically relevant information, i.e., qualitative heterogeneities of performance within the patient sample. This heterogeneity is crucial in the variability debate.     

Agency and authenticity: Which value grounds patient choice?

In current American medical practice, autonomy is assumed to be more valuable than human life: if a patient autonomously refuses lifesaving treatment, the doctors are supposed to let him die. In this paper we discuss two values that might be at stake in such clinical contexts. Usually, we hear only of autonomy and best interests. However, here, autonomy is ambiguous between two concepts—concepts that are tied to different values and to different philosophical traditions. In some cases, the two values (that of agency and that of authenticity) entail different outcomes. We argue that the comparative value of these values needs to be assessed.     

The Dialogue Between Religion and Science: Which God?

As exemplified by three cases, difficulties in the dialogue between religion and science not infrequently arise from differing views of God's omnipotence and omniscience. From the side of theology, reflections on the biblical and church-related sources of those views, on Auschwitz and theproblem of theodicy, on God as Creator of the universe, and on how to read and interpret the Bible show that a view of a God who self-limits almightiness and all-knowing in order to grant freedom and functional integrity to a Creation about which God cares can be multiply justified. Such a view is not dissonant with regard to a self-organized, open universe, producing "unexpected" emergent features as seen by science     

Ethics and Social Science: Which Kind of Co-operation?

The relation between ethics and social science is often conceived as complementary, both disciplines cooperating in the solution of concrete moral problems. Against this, the paper argues that not only applied ethics but even certain parts of general ethics have to incorporate sociological and psychological data and theories from the start. Applied ethics depends on social science in order to asses the impact of its own principles on the concrete realities which these principles are to regulate as well as in order to propose practice rules suited to adapt these principles to their respective contexts of application. Examples from medical ethics (embryo research) and ecological ethics (Leopold's land ethic) illustrate both the contingence of practice rules in relation to their underlying basic principles and the corresponding need for a co-operation between philosophy and empirical disciplines in judging their functional merits and demerits. In conclusion, the relevance of empirical hypotheses even for some of the perennial problems of ethics is shown by clarifying the role played by empirical theories in the controversies about the ethical differentiation between positive and negative responsibility and the relation between utility maximisation and (seemingly) independent criteria of distributive justice in the context of social distributions.     

To Hook Up or Date: Which Gender Benefits?

Hooking up on college campuses has become more frequent than dating in heterosexual sexual interaction. Analysis of the relative benefits and costs associated with dating and hooking up suggest that women benefit more from dating while men benefit more from hooking up. U.S students (150 women, 71 men) at a midsized southeastern university indicated preferences for dating and hooking up across a number of situations and indicated the perceived benefits and risks associated with each. As hypothesized, in most situations women more than men preferred dating and men more than women preferred hooking up. Both genders perceived similar benefits and risks to dating and hooking up; differences provided insight into the sexual motives of college women and men.     

Decision-making competence and cognitive abilities: Which abilities matter?

Decision-making competence is a skill that is associated with numerous positive life outcomes. Even though multiple cognitive abilities have been shown to predict decision-making competence, few studies have incorporated a large test battery tapping into several cognitive abilities concurrently in the same models. The current paper presents a study that sought to investigate which cognitive abilities predicted overall decision-making competence in adults using hierarchical regression analysis. A cognitive test battery, comprising abilities such as general intelligence, executive functions, numeracy, visuospatial ability, and time perception, was administered to 182 participants. Results indicate that both general intelligence, which was consistently the strongest predictor, and numeracy contributed independently to overall decision-making competence. Executive functions did predict overall decision-making competence, while all predictors were included in the models. A novel finding concerns the relationship between time perception and decision-making competence. The complementary roles of these cognitive abilities are discussed.     

Emotion Regulation and Empathy: Which Relation with Social Conduct?

A shared consensus among researchers deals with the positive association between the ability to effectively regulate and manage one's emotion and the engagement in empathic behavior and morally desirable actions. This study was designed to investigate how dispositional reliance on suppression and reappraisal differently impacted on the cognitive and affective components of empathy and on social conduct, distinguishing among prosocial, internalizing, and externalizing behaviors. Two hundred nineteen middle adolescents were enrolled and fulfilled self-reports assessing emotion regulation strategies, empathy, and social behaviors. The results suggest that there are important distinctions among the emotion regulation strategies and the components of empathy as they relate to one another and to prosocial behavior and problem conduct. Specifically, cognitive reappraisal was related to prosocial behavior through empathic concern. While internalizing behavior was associated with emotion regulation strategies, externalizing behavior was only related to perspective-taking ability. Delimitations and practical implications were discussed.     

Infant visual responses to pattern: Which metric perdicts best?

Visual fixations were recorded in newborn, 4-, and 8-week old human infants as they scanned displays that varied along several dimensions. These displays were designed to evaluate four metrics that have been theorized to control infant visual preference: Contour length, size, number, and a new metric, CVAL, based on Contour Variability, Amount, and Location. This latter metric reflects characteristics of the visual system that other metrics ignore. Both contour length and CVAL separately accounted for approximately 95% of looking-duration variance, a much larger portion than the other metrics considered; however, CVAL accounted for more looking variance than contour length when the number of lines and contour length were deconfounded, and uniquely accommodated a large orientation effect. Finally, several predictions were confirmed about characteristics of visual scanning. Retinal structure and natural scanning dispositions should be considered in accounts of infants' reactions to visual stimuli.     

Escaping the recent past: Which stimulus dimensions influence proactive interference?

Proactive interference occurs when information from the past disrupts current processing and is a major source of confusion and errors in short-term memory (STM; Wickens, Born, & Allen, Journal of Verbal Learning and Verbal Behavior, 2:440–445, 1963). The present investigation examines potential boundary conditions for interference, testing the hypothesis that potential competitors must be similar along task-relevant dimensions to influence proactive interference effects. We manipulated both the type of task being completed (Experiments 1, 2, and 3) and dimensions of similarity irrelevant to the current task (Experiments 4 and 5) to determine how the recent presentation of a probe item would affect the speed with which participants could reject that item. Experiments 1, 2, and 3 contrasted STM judgments, which require temporal information, with semantic and perceptual judgments, for which temporal information is irrelevant. In Experiments 4 and 5, task-irrelevant information (perceptual similarity) was manipulated within the recent probes task. We found that interference from past items affected STM task performance but did not affect performance in semantic or perceptual judgment tasks. Conversely, similarity along a nominally irrelevant perceptual dimension did not affect the magnitude of interference in STM tasks. Results are consistent with the view that items in STM are represented by noisy codes consisting of multiple dimensions and that interference occurs when items are similar to each other and, thus, compete along the dimensions relevant to target selection.
