Thing, Value, Time, and Freedom: A Consideration of Some Key Concepts in Marx’s Philosophical System

Criticizing the misunderstanding and wrong explanation of Marx’s philosophical system made by recent Chinese textbooks on Marxist philosophy, the author argues that Marx’s philosophy has practical, economical-philosophical, and ontological dimensions and stresses on reconstructing Marx’s philosophical system through synthesizing the above three dimensions. This paper intends to set up a new outline of Marx’s philosophical system, in terms of the following four concepts—thing, value, time, and freedom.

Quantification over Sets of Possible Worlds in Branching-Time Semantics

Temporal logic is one of the many areas in which a possible world semantics is adopted. Prior's Ockhamist and Peircean semantics for branching-time, though, depart from the genuine Kripke semantics in that they involve a quantification over histories, which is a second-order quantification over sets of possible worlds. In the paper, variants of the original Prior's semantics will be considered and it will be shown that all of them can be viewed as first-order counterparts of the original semantics.     

The On-line Study of Sentence Comprehension: An Examination of Dual Task Paradigms

This paper presents three studies which examine the susceptibility of sentence comprehension to intrusion by extra-sentential probe words in two on-line dual-task techniques commonly used to study sentence processing: the cross-modal lexical priming paradigm and the unimodal all-visual lexical priming paradigm. It provides both a general review and a direct empirical examination of the effects of task-demand in the on-line study of sentence comprehension. In all three studies, sentential materials were presented to participants together with a target probe word which constituted either a better or a worse continuation of the sentence at a point at which it was presented. Materials were identical for all three studies. The manner of presentation of the sentence materials was, however, manipulated; presentation was either visual, auditory (normal rate) or auditory (slow rate). The results demonstrate that a technique in which a visual target probe interrupts ongoing sentence processing (such as occurs in unimodal visual presentation and in very slow auditory sentence presentation) encourages the integration of the probe word into the on-going sentence. Thus, when using such ‘sentence interrupting’ techniques, additional care to equate probes is necessary. Importantly, however, the results provide strong evidence that the standard use of fluent cross-modality sentence investigation methods are immune from such external probe word intrusions into ongoing sentence processing and are thus accurately reflect underlying comprehension processes.

Sexual differences in memory in shiny cowbirds

Avian brood parasites depend on other species, the hosts, to raise their offspring. During the breeding season, parasitic cowbirds (Molothrus sp.) search for potential host nests to which they return for laying a few days after first locating them. Parasitic cowbirds have a larger hippocampus/telencephalon volume than non-parasitic species; this volume is larger in the sex involved in nest searching (females) and it is also larger in the breeding than in the non-breeding season. In nature, female shiny cowbirds Molothrus bonariensis search for nests without the male’s assistance. Here we test whether, in association with these neuroanatomical and behavioural differences, shiny cowbirds display sexual differences in a memory task in the laboratory. We used a task consisting of finding food whose location was indicated either by the appearance or the location of a covering disk. Females learnt to retrieve food faster than males when food was associated with appearance cues, but we found no sexual differences when food was associated with a specific location. Our results are consistent with the view that parasitism and its neuroanatomical correlates affect performance in memory tasks, but the effects we found were not in the expected direction, emphasising that the nature of avian hippocampal function and its sexual differences are not yet understood.

Enrichment and Stress in Families Caring for a Child with a Serious Emotional Disorder

We examined enrichment and stress in 214 families who had children with severe emotional disorders. Caregivers' ratings of enrichment and stress were obtained through a newly developed instrument, the Effects of the Situation Questionnaire, which used parallel items covering 17 life areas. While ratings of stress were generally higher than enrichment, caregivers reported some enrichment in areas encompassing self concept and family relationships, Bivariate and multivariate analyses using various child, family, and service-system variables revealed that stress was notably associated with severity of the child's disorder, low empowerment, and a lack of coordination among service providers. Enrichment was unrelated to severity but associated with high empowerment and spiritual support. Our findings suggest that families' experiences of caregiving can have both positive and negative aspects and that a comprehensive approach to serving and studying families should take both into account.     

Conditions under which children experience inhibitory difficulty with a "button-press" go/no-go task

Go/no-go tasks seem to provide a simple marker of inhibitory development in young children. Children are told to respond to one stimulus on go trials but to make no response to another stimulus on no-go trials; responding on no-go trials is assumed to reflect a failure to inhibit the go response. However, there is evidence to suggest that a type of go/no-go task, which we call the "button-press" task, does not require inhibition. We investigated the conditions under which young children (M=3 years 6 months, N=120) experience inhibitory difficulty with this type of task. The data suggest that the speed of stimulus presentation is crucial and that other studies using this type of task have presented the stimuli too briefly. The importance of establishing the inhibitory credentials of a task before it is used as a marker of inhibitory control is emphasized.     

Realism in confidence judgements of performance based on implicit learning

In two experiments we employed calibration methods to investigate the realism of participants' confidence ratings of their own classification performance based on knowledge acquired after training on an artificial grammar. In Experiment 1 participants showed good realism (but overconfidence) for grammatical strings but very poor realism for non-grammatical strings. Method of training (string repetition in writing or mere exposure) did not affect the realism. Furthermore, the participants underestimated their overall performance. In Experiment 2, using a more complex grammar and controlling for two types of associative chunk-strength, participants showed good realism (but still overconfidence) for both letter and symbol strings, irrespective of grammaticality. Together, these experiments show that implicit learning can give rise to knowledge products that are associated with fairly realistic meta-knowledge. It is argued that both the zero-correlation criterion and the guessing criterion are misplaced when used to define implicit knowledge; two reasons being that confidence judgements may be affected both by implicit knowledge and by inferences.     

Belief–logic conflict resolution in syllogistic reasoning: Inspection-time evidence for a parallel-process model

An experiment is reported examining dual-process models of belief bias in syllogistic reasoning using a problem complexity manipulation and an inspection-time method to monitor processing latencies for premises and conclusions. Endorsement rates indicated increased belief bias on complex problems, a finding that runs counter to the “belief-first” selective scrutiny model, but which is consistent with other theories, including “reasoning-first” and “parallel-process” models. Inspection-time data revealed a number of effects that, again, arbitrated against the selective scrutiny model. The most striking inspection-time result was an interaction between logic and belief on premise-processing times, whereby belief – logic conflict problems promoted increased latencies relative to non-conflict problems. This finding challenges belief-first and reasoning-first models, but is directly predicted by parallel-process models, which assume that the outputs of simultaneous heuristic and analytic processing streams lead to an awareness of belief – logic conflicts than then require time-consuming resolution.     

The Contribution of Common Principles of Canon Law to Ecclesial Communion in Anglicanism

An important recent development in worldwide Anglicanism is the emergence over recent years of a project to articulate the principles of canon law common to the churches of the Anglican Communion. This project seeks to express the juridical character of Anglicanism from a global perspective, not only to underscore the many fundamental values that Anglicans share in terms of their polity, ministry, doctrine, liturgy, rites and property, going to the very roots of Anglican identity but, also, as a concrete resource for other churches in ecumenical dialogue with Anglicans. This article traces the development of the so-called ius commune project, describes the methodological challenges which it faces and, the process of producing a draft. It also seeks to compare the project with the juridical experiences of other international ecclesial communities and, briefly, to place the project in the context of the debate about the adoption of an Anglican Covenant, an initiative proposed by the Lambeth Commission in 2004.
