Two experiments were conducted to investigate the psychological refractory period (PRP), a delay induced into the second of two reaction times (RT) when the interstimulus interval (ISI) is short. In Experiment1, time and event uncertainty were factorially varied by providing or not providing S with foreknowledge of the ISI and the order in which the two events would occur, respectively. ISIs of0, 50, 100, 200, and400 msec were used. Time and event uncertainty produced independent degradation of both RTs. Also, the second RT (RT 2 ) was delayed at50 msec ISI when both time and event certainty were present. Experiment 2 attempted to replicate this latter finding using ISIs of0, 25, 50, 75, and100 msec. Delays in RT 2 were found for the middle three values of ISI. These results were interpreted as supporting a modified single channel theory of the PRP.  相似文献

According to Hempel’s (Aspects of scientific explanation and other essays. The Free Press, New York, 1965) influential theory of explanation, explaining why some a is G consists in showing that the truth that a is G follows from a law-like generalization to the effect that all Fs are G together with the initial condition that a is F. While Hempel’s overall account is now widely considered to be deeply flawed, the idea that some generalizations play the explanatory role that the account predicts is still often endorsed by contemporary philosophers of science. This idea, however, conflicts with widely shared views in metaphysics according to which the generalization that all Fs are G is partially explained by the fact that a is G. I discuss two solutions to this conflict that have been proposed recently, argue that they are unsatisfactory, and offer an alternative.  相似文献

Orthomodular lattices with a two-valued Jauch–Piron state split into a generalized orthomodular lattice (GOML) and its dual. GOMLs are characterized as a class of L-algebras, a quantum structure which arises in the theory of Garside groups, algebraic logic, and in connections with solutions of the quantum Yang–Baxter equation. It is proved that every GOML X embeds into a group G(X) with a lattice structure such that the right multiplications in G(X) are lattice automorphisms. Up to isomorphism, X is uniquely determined by G(X), and the embedding \(X\hookrightarrow G(X)\) is a universal group-valued measure on X.  相似文献

There is considerable evidence that self-criticism plays a major role in the vulnerability to and recovery from psychopathology. Methods to measure this process, and its change over time, are therefore important for research in psychopathology and well-being. This study examined the factor structure of a widely used measure, the Forms of Self-Criticising/Attacking & Self-Reassuring Scale in thirteen nonclinical samples (N?=?7510) from twelve different countries: Australia (N?= 319), Canada (N?= 383), Switzerland (N?= 230), Israel (N?=?476), Italy (N?=?389), Japan (N?=?264), the Netherlands (N?=?360), Portugal (N?=?764), Slovakia (N?=?1326), Taiwan (N?=?417), the United Kingdom 1 (N?=?1570), the United Kingdom 2 (N?=?883), and USA (N?=?331). This study used more advanced analyses than prior reports: a bifactor item-response theory model, a two-tier item-response theory model, and a non-parametric item-response theory (Mokken) scale analysis. Although the original three-factor solution for the FSCRS (distinguishing between Inadequate-Self, Hated-Self, and Reassured-Self) had an acceptable fit, two-tier models, with two general factors (Self-criticism and Self-reassurance) demonstrated the best fit across all samples. This study provides preliminary evidence suggesting that this two-factor structure can be used in a range of nonclinical contexts across countries and cultures. Inadequate-Self and Hated-Self might not by distinct factors in nonclinical samples. Future work may benefit from distinguishing between self-correction versus shame-based self-criticism.  相似文献

While inanimate objects can neither experience nor express emotions, in principle they can be expressive of emotions. In particular, music is a paradigmatic example of something expressive of emotions that surely cannot feel anything at all. The Contour theory accounts for music expressiveness in terms of those resemblances that hold between its external and perceivable properties (i.e., its contour) and the typical contour of human emotional behavior. Provided that some critical aspects are emended – notably, the stress on the perception of similarity instead of the more plausible hypothesis that the listener perceives manifestations that are similar – we are inclined to endorse contour theory. In particular, we share its basic idea that expressive properties are perceived. Although other kinds of processes – high-level conceptual inferences, imagination – sometimes characterize our encounters with music, still perception constitutes the standard process underlying the detection of expressiveness. Moreover, we propose to extend contour theory to visual arts. Taking into consideration, as a case study, depicted landscapes, we observe that they frequently cannot but express emotions such as joy, sadness, liveliness or melancholy. The fact that pictures, unlike music, lack any temporal dimension is a prima facie reason for doubting the extendibility of contour theory’s conceptual arsenal to them. Nevertheless, while being obviously unable to behave somehow, we claim that depicted landscapes can perfectly convey dynamic information. If this is the case, the extension of the notion of contour to visuals art via the stress on the notion of dynamism would represent a second interesting revision of contour theory.  相似文献

We are familiar with various set-theoretical paradoxes such as Cantor's paradox, Burali-Forti's paradox, Russell's paradox, Russell-Myhill paradox and Kaplan's paradox. In fact, there is another new possible set-theoretical paradox hiding itself in Wittgenstein’s Tractatus (Wittgenstein 1989). From the Tractatus’s Picture theory of language (hereafter LP) we can strictly infer the two contradictory propositions simultaneously: (a) the world and the language are equinumerous; (b) the world and the language are not equinumerous. I call this antinomy the world-language paradox. Based on a rigorous analysis of the Tractatus, with the help of the technical resources of Cantor’s naive set theory (Cantor in Mathematische Annalen, 46, 481–512, 1895, Mathematische Annalen, 49, 207–246, 1897) and Zermelo-Fraenkel set theory with the axiom of choice (hereafter ZFC) (Jech 2006: 3–15; Kunen 1992: xv–xvi; Bagaria 2008: 619–622), I outline the world-language paradox and assess the unique possible solution plan, i.e., the mathematical plan utilizing ‘infinity’. I conclude that Wittgenstein cannot solve the hidden set-theoretical paradox of the Tractatus successfully unless he gives up his finitism.  相似文献

In Mathematics is megethology (Lewis (1993). Philosophia Mathematica, 1(1), 3–23) David K. Lewis proposes a structuralist reconstruction of classical set theory based on mereology. In order to formulate suitable hypotheses about the size of the universe of individuals without the help of set-theoretical notions, he uses the device of Boolos’ plural quantification for treating second order logic without commitment to set-theoretical entities. In this paper we show how, assuming the existence of a pairing function on atoms, as the unique assumption non expressed in a mereological language, a mereological foundation of set theory is achievable within first order logic. Furthermore, we show how a mereological codification of ordered pairs is achievable with a very restricted use of the notion of plurality without plural quantification.  相似文献

There seem to be two ways of supposing a proposition: supposing “indicatively” that Shakespeare didn’t write Hamlet, it is likely that someone else did; supposing “subjunctively” that Shakespeare hadn’t written Hamlet, it is likely that nobody would have written the play. Let P(B//A) be the probability of B on the subjunctive supposition that A. Is P(B//A) equal to the probability of the corresponding counterfactual, A B? I review recent triviality arguments against this hypothesis and argue that they do not succeed. On the other hand, I argue that even if we can equate P(B//A) with P(A B), we still need an account of how subjunctive conditional probabilities are related to unconditional probabilities. The triviality arguments reveal that the connection is not as straightforward as one might have hoped.  相似文献

The study assessed 30-month-old Mandarin-speaking children’s awareness of aspectual distinctions involving the perfective marker le and the imperfective marker zhe in a preferential looking experiment. In the experiment, we presented our child subjects with a choice between two video clips (one depicting a closed event and the other depicting an on-going event), in the presence of an auditory stimulus (either the le sentence, the zhe sentence or the control sentence without any aspect marker). Children’s looking behavior in the task was recorded and analyzed. The results revealed 30-month-old children’s emerging sensitivity to the aspectual contrast between le and zhe. This was manifest by an increase in looking to the closed event when hearing the le sentence and an increase in looking to the on-going event when hearing the zhe sentence. The absence of le or zhe in the control sentence did not result in any increase or decrease in looking to either event. We also found that the effect of le on children’s looking behavior was immediate whereas the effect of zhe was late. We attributed this difference to the facilitative role of le in children’s sentence processing as well as their preference for the event boundary. The results lend support to the continuity view that functional morphemes like aspect markers are available to children early in language development.  相似文献

According to one argument for Animalism about personal identity, animal, but not person, is a Wigginsian substance concept—a concept that tells us what we are essentially. Person supposedly fails to be a substance concept because it is a functional concept that answers the question “what do we do?” without telling us what we are. Since person is not a substance concept, it cannot provide the criteria for our coming into or going out of existence; animal, on the other hand, can provide such criteria. This argument has been defended by Eric Olson, among others. I argue that this line of reasoning fails to show Animalism to be superior to the Psychological Approach, for the following two reasons: (1) human animal, animal, and organism are all functional concepts, and (2) the distinction between what something is and what it does is illegitimate on the reading that the argument needs.  相似文献

Contemporary literature has emphasized the vital role of supervision in the professional growth of counselors and therapists. Even some counselor developmental models argued that improvement in counselor autonomy, motivation, and self-efficacy is highly contingent upon counseling supervision, especially in Western settings. Yet, there is marked scarcity of studies examining the antecedents of flow in non-Western contexts. As such, the central aim of the current study was to assess the moderating effects of perceived autonomy support from supervisors on the relations between counseling self-efficacy (CSE) and state flow among Filipino counselors. A sample of 131 Filipino counselors in Metro Manila participated in the research through answering questionnaires that measured the aforementioned constructs. The findings of correlational analyses have shown that counseling self-efficacy and perceived autonomy support are positively associated with state flow. The results of path analysis revealed a significant moderation effect. This suggests that for Filipino counselors who had greater perceptions that their supervisors provide autonomy in their counseling practice (perceived autonomy support), having lower perceived capabilities in performing counseling duties may lead to higher immersion and enjoyment in counseling activities, while for those who have low perceived autonomy support, having higher levels of counseling self-efficacy will lead to lower flow. Implications of these findings in theory and practice are elucidated.  相似文献

Lifecourse theory scholars focus on how individuals traverse social roles, such as marriage, parenthood, and employment, in similar and different ways across their lives. This study examined one specific role trajectory: romantic relationships. This study examined men’s and women’s (N?=?3617) relationship status and quality across approximately 30 years. Using second-order latent class analysis, results showed four predominant relationship role trajectories: (a) Multiple Transitions, (b) Stable Marriage with High Conflict, (c) Stable Marriage with High Satisfaction, and (d) Marriage to Divorce/cohabitation. These relationship role trajectories differed on two aspects of quality of life: life satisfaction and depressive symptoms. Individuals in the Multiple Transitions trajectory consistently reported poorest quality of life; however, those in the Multiple Transitions and Stable Marriage with High Conflict trajectories were the only that reported decreases in depressive symptoms over 30 years. Relationship satisfaction poorly differentiated the trajectories compared to relationship conflict and stability.  相似文献

The current study compared parents’ emotion regulation (ER) in clinical (those with a child with externalizing behavioral problems) and low-risk comparison families. Additionally, mediation models were explored with parent ER predicting child behavior problems through child ER. Participants were 60 families with children (71.7% boys; 73% Caucasian) ages 2 through 8 years (M?=?4.62; SD?=?1.69) from a rural population in the United States: 34 clinical families referred for parent training and 26 nonclinical families. A blocking design was used to balance the two groups on key demographic characteristics. Parents’ and children’s ER was assessed using parent-report surveys and structured behavioral observations. Analyses indicated higher rates of parental emotion dysregulation (specifically, more difficulty when upset with achieving goal-directed behaviors, p?=?.01, d?=?0.67; controlling impulses, p?=?.01, d?=?0.64; limited use of ER strategies, p?=?.02, d?=?0.62; and more negative verbalizations to their child during the observed task, p?<?.01, d?=?0.73) and child emotion dysregulation (specifically, more difficulty as reported by parents, p?<?.01, d?=??2.42) in the clinical group. Mediational analyses indicated there were indirect paths from parental ER to children’s behavioral problems through child ER. Findings from this research suggest a need to measure and target ER in both parents and their children when working with families who are referred for treatment of child behavior problems.  相似文献

A survey of just war theory literature reveals the existence of quite different lists of principles. This apparent arbitrariness raises a number of questions: What is the relation between ad bellum and in bello principles? Why are there so many of the former and so few of the latter? What order is there among the various principles? To answer these questions, I first draw on some recent work by Jeff McMahan to show that ad bellum and in bello principles are not, as often portrayed, independent—the justice of conduct in war largely presupposes the justice of the recourse to war. Undermining this independence claim is one important step toward revealing the unified logical structure of just war theory. I then argue that we can see the dependence of the jus in bello upon the jus ad bellum, not just in the content of certain principles, but also in the structure of the two sets of principles: I construct a one-to-one mapping between ad bellum and in bello principles. In doing so, I argue also that the shared structure successfully finds place for the questions central to the evaluation of the morality of war: what is a sufficient provocation to use force, what objectives may be sought by force, why or for what ends, who has authority to decide to use force, and when or in what circumstances? Despite variations in expression, the theory allows for a coherent and comprehensive evaluation of morality in warfare.  相似文献

This study investigated 5-year-old Mandarin-speaking children’s comprehension of wh-questions, universal statements and free choice inferences. Previous research has found that Mandarin-speaking children assign a universal interpretation to sentences with a wh-word (e.g., shei ‘who’) followed by the adverbial quantifier dou ‘all’ (Zhou in Appl Psycholinguist 36:411–435, 2013). Children also compute free choice inferences in sentences that contain a modal verb in addition to a wh-word and dou (Zhou, in: Nakayama, Su, Huang (eds.) Studies in Chinese and Japanese language acquisition: in honour of Stephen Crain. John Benjamins Publishing Company, Amsterdam, pp 223–235, 2017). The present study used a Question-Statement Task to assess children’s interpretation of sentences containing shei + dou, both with and without the modal verb beiyunxu ‘was allowed to’, as well as the contrast between sentences with shei + dou, which are statements for adults, versus ones with dou + shei, which are wh-questions for adults. The 5-year-old Mandarin-speaking child participants exhibited adult-like linguistic knowledge of the semantics and pragmatics of wh-words, the adverbial quantifier dou, and the deontic modal verb beiyunxu.  相似文献

Research suggests that quieting the ego (reducing excessive self-focus) can foster well-being. Two exploratory qualitative studies were carried out to investigate the features of ego-quieting group activities. Romanian (N = 140) and Japanese participants (N = 99) read a definition of “self-detachment” and answered several open-ended questions asking them to describe a group situation in which they had experienced a similar state. Thematic analysis showed numerous similarities between the responses of the two samples, as well as cultural-specific features. Participants recalled moments of enjoyment in the company of friends, or challenging group work. For the Romanian sample, the experience was characterized by present-oriented attention, valuing others, positivity, disinhibition and altered perceptions, while for the Japanese sample, valuing others, stress relief, matching challenge and skill and merging self with exterior world were its prevalent features. Both samples identified similar eliciting factors (individual receptiveness, acceptant group, captivating activity, appropriate environment) and similar consequences of the experience (increased closeness, relaxation and self-development). While supporting the existing literature on the importance of communal activities in reducing self-focus and promoting individual well-being, the paper provides new in-depth insights into participants’ subjective experiences and the cultural specifics of positive group activities.  相似文献

The bundle theory is a theory about the internal constitution of individuals. It asserts that individuals are entirely composed of universals. Typically, bundle theorists augment their theory with a constitutional approach to individuation entailing the thesis ‘identity of constituents is a sufficient ground for numerical identity’ (CIT). But then the bundle theory runs afoul of Black’s duplication case—a world containing two indiscernible spheres. Here I propose and defend a new version of the bundle theory that denies ‘CIT’, and which instead conjoins it with a structural diversity thesis, according to which being separated by distance is a sufficient ground for numerical diversity. This version accommodates Black’s world as well as the three-spheres world—a world containing three indiscernible spheres, arranged as the vertices of an equilateral triangle. In this paper, I also criticize Rodriguez-Pereyra’s alternative attempt to defend the bundle theory against Black’s case and the case of the three-spheres world.  相似文献

Task-irrelevant spatial information, conveyed by stimulus location, location word, or arrow direction, can influence the response to task-relevant attributes, generating the location-, word-, and arrow-based Simon effects. We examined whether different mechanisms are involved in the generation of these Simon effects by fitting a mathematical ex-Gaussian function to empirical response time (RT) distributions. Specifically, we tested whether which ex-Gaussian parameters (μ, σ, and τ) show Simon effects and whether the location-, word, and arrow-based effects are on different parameters. Results show that the location-based Simon effect occurred on mean RT and μ but not on τ, and a reverse Simon effect occurred on σ. In contrast, a positive word-based Simon effect was obtained on all these measures (including σ), and a positive arrow-based Simon effect was evident on mean RT, σ, and τ but not μ. The arrow-based Simon effect was not different from the word-based Simon effect on τ or σ but was on μ and mean RT. These distinct results on mean RT and ex-Gaussian parameters provide evidence that spatial information conveyed by the various location modes are different in the time-course of activation.  相似文献

In concrete applications of probability, statistical investigation gives us knowledge of some probabilities, but we generally want to know many others that are not directly revealed by our data. For instance, we may know prob(P/Q) (the probability of P given Q) and prob(P/R), but what we really want is prob(P/Q&;R), and we may not have the data required to assess that directly. The probability calculus is of no help here. Given prob(P/Q) and prob(P/R), it is consistent with the probability calculus for prob(P/Q&;R) to have any value between 0 and 1. Is there any way to make a reasonable estimate of the value of prob(P/Q&;R)? A related problem occurs when probability practitioners adopt undefended assumptions of statistical independence simply on the basis of not seeing any connection between two propositions. This is common practice, but its justification has eluded probability theorists, and researchers are typically apologetic about making such assumptions. Is there any way to defend the practice? This paper shows that on a certain conception of probability—nomic probability—there are principles of “probable probabilities” that license inferences of the above sort. These are principles telling us that although certain inferences from probabilities to probabilities are not deductively valid, nevertheless the second-order probability of their yielding correct results is 1. This makes it defeasibly reasonable to make the inferences. Thus I argue that it is defeasibly reasonable to assume statistical independence when we have no information to the contrary. And I show that there is a function Y(r, s, a) such that if prob(P/Q) = r, prob(P/R) = s, and prob(P/U) = a (where U is our background knowledge) then it is defeasibly reasonable to expect that prob(P/Q&;R) = Y(r, s, a). Numerous other defeasible inferences are licensed by similar principles of probable probabilities. This has the potential to greatly enhance the usefulness of probabilities in practical application.  相似文献

Research suggests that a feature-matching process underlies cue familiarity-detection when cued recall with graphemic cues fails. When a test cue (e.g., potchbork) overlaps in graphemic features with multiple unrecalled studied items (e.g., patchwork, pitchfork, pocketbook, pullcork), higher cue familiarity ratings are given during recall failure of all of the targets than when the cue overlaps in graphemic features with only one studied target and that target fails to be recalled (e.g., patchwork). The present study used semantic feature production norms (McRae et al., Behavior Research Methods, Instruments, & Computers, 37, 547–559, 2005) to examine whether the same holds true when the cues are semantic in nature (e.g., jaguar is used to cue cheetah). Indeed, test cues (e.g., cedar) that overlapped in semantic features (e.g., a_tree, has_bark, etc.) with four unretrieved studied items (e.g., birch, oak, pine, willow) received higher cue familiarity ratings during recall failure than test cues that overlapped in semantic features with only two (also unretrieved) studied items (e.g., birch, oak), which in turn received higher familiarity ratings during recall failure than cues that did not overlap in semantic features with any studied items. These findings suggest that the feature-matching theory of recognition during recall failure can accommodate recognition of semantic cues during recall failure, providing a potential mechanism for conceptually-based forms of cue recognition during target retrieval failure. They also provide converging evidence for the existence of the semantic features envisaged in feature-based models of semantic knowledge representation and for those more concretely specified by the production norms of McRae et al. (Behavior Research Methods, Instruments, & Computers, 37, 547–559, 2005).  相似文献
