The Time-symmetric Gold Universe Reconsidered

The present article proposes to re-examine the parity-of-reasoning or double-standard fallacy argument, which favours a time-symmetric Gold universe model over a cosmological arrow of time. There are two reasons for this re-examination. One is empirical: the recent discovery of an expanding and accelerating universe questions the symmetry assumption of the Gold universe on empirical grounds. The other is theoretical: the argument from t-symmetry fails to take into account some important aspects of the topology of phase space and recently developed typicality arguments. If the parity-of-reasoning argument, which depends on the t-symmetry of probability, is reconsidered in terms of the topology of phase space and typicality arguments, the double-standard fallacy argument loses much of its appeal. The Gold universe model itself suffers from unexplained dynamic asymmetries. The upshot of this article is that the Gold universe model is implausible or far less plausible than asymmetric models.     

Forgiveness and Suicidal Behavior: Cynicism and Psychache as Serial Mediators

Research is burgeoning regarding the beneficial association of forgiveness with numerous health-related outcomes; however, its particular relationship to suicidal behavior has received relatively little attention. Both cynicism and psychache, or agonizing psychological pain, have displayed deleterious associations with suicidal behavior, but have rarely been incorporated into more comprehensive models of suicidal behavior. Consistent with the recent development of a theoretical model regarding the forgiveness–suicidal behavior association, the present study utilized an undergraduate sample of college students (N = 312) to test a mediation-based model of the cross-sectional association of forgiveness with suicidal behavior, as serially mediated by cynicism and psychache. Dispositional forgiveness of self and forgiveness of uncontrollable situations were each indirectly associated with less suicidal behavior via less psychache. Also, dispositional forgiveness of others was indirectly associated with less suicidal behavior via less cynicism and less psychache, in a serial fashion. The present results are consistent with the extent literature on the forgiveness–suicidal behavior association, cynicism, and psychache, and pending future studies, may be utilized to inform further treatment efforts for individuals at a high risk of attempting suicide.     

Initial goals,goal trajectories,and changes in perceived resolvability during serial arguments

This study examined how dyadic patterns of goal importance during a serial argument interaction predict changes in perceptions of argument resolvability over the course of a specific episode. Seventy romantic couples engaged in a 7‐min discussion of a current serial argument and used a video‐assisted recall method to report their goals at each minute. Although arguers' initial goals did not predict changes in perceptions of resolvability, increases in a partner's endorsement of partner‐identity goals predicted increases in individuals' own perceptions of resolvability. Conversely, increases in a partner's endorsement of self‐identity goals predicted declines in individuals' perceived resolvability. Results suggest that trajectories of identity‐focused goals during serial argument episodes may shape the progress of argument perceptions toward or away from resolvability.     

Higher Order Chunking in Serial Pattern Learning by Rats in the T-Maze

Rats were repeatedly exposed to two- and three-trial series consisting of different reinforced (R) and nonreinforced (N) trials in a fixed order on extended visually distinct runways in a T-maze. When initially presented with the same sequence, RR or RN in Experiment 1 and RRN or RNR in Experiment 2, on each series in a session (Separate Presentations), rats developed slower running speeds or bypassed the runway in returning to the start chamber on N more than on R trials. These serial response patterns occurred whether rats experienced each sequence on a specific runway (Associated group) or equally on different runways over sessions (Nonassociated group). When sequences were intermixed within each session, only the Associated group maintained its serial pattern responses to both sequences while the Nonassociated group only did so within the RRN sequence. When allowed to choose between runways over trials, the Associated group tended to select the runway associated with the RR sequence on the first two free-choice trials while rats in the Nonassociated group tended to alternate their choices of runways. Switching the relevancy of the runway context in the second experiment caused rats in each group to react like rats in the other group on forced-choice trials. In terms of Capaldi's (1992) model of levels of chunking in serial pattern learning, our findings indicate that rats learned to anticipate at least second trial outcomes by using higher order list or contextually cued chunking and also to anticipate third trial outcomes by using lower order series chunking.     

Comparing the Argumentum Model of Topics to Other Contemporary Approaches to Argument Schemes: The Procedural and Material Components

This paper focuses on the inferential configuration of arguments, generally referred to as argument scheme. After outlining our approach, denominated Argumentum Model of Topics (AMT, see Rigotti and Greco Morasso 2006, 2009; Rigotti 2006, 2008, 2009), we compare it to other modern and contemporary approaches, to eventually illustrate some advantages offered by it. In spite of the evident connection with the tradition of topics, emerging also from AMT’s denomination, its involvement in the contemporary dialogue on argument schemes should not be overlooked. The model builds in particular on the theoretical and methodological perspective of pragma-dialectics in its extended version, reconciling dialectic and rhetoric; nevertheless, it also takes into account numerous other contributions to the study of argument schemes. Aiming at a representation of argument schemes able to monitor the inferential cohesion and completeness of arguments, AMT focuses on two components of argument scheme that could be distinguished, readapting pragma-dialectical terms, as procedural and material respectively. The procedural component is based on the semantic-ontological structure, which generates the inferential connection from which the logical form of the argument is derived. The material component integrates into the argument scheme the implicit and explicit premises bound to the contextual common ground (Rigotti 2006). In this paper, the comparison of the AMT to other approaches focuses on the inferential configuration of arguments and not on the typologies of argument schemes and on the principles they are based on, which the authors intend to tackle in a further paper.     

Application of the Serious Leisure Perspective to Intrinsically Motivated Serial Homicide

ABSTRACT

This article briefly introduces the multidisciplinary field of leisure sciences before exploring how leisure theory, particularly the Serious Leisure Perspective, can provide important insights into better understanding some forms of serial homicide. It is well known that many serial homicide offenders kill for the pleasure and enjoyment that such behavior provides them. Such expressive cases can be understood as deviant casual, serious, or project-based leisure experience, which helps account for how particular offenders plan, structure, and experience their crimes. Examples of specific serial homicide cases that appear to function primarily as casual, serious, or project-based leisure are presented and discussed.     

The Phenomenological Failure of Groundwork III

Henry Allison and Paul Guyer have recently offered interpretations of Kant's argument in Groundwork III. These interpretations share this premise: the argument moves from a non-moral, theoretical premise to a moral conclusion, and the failure of the argument is a failure to make this jump from the non-moral to the moral. This characterization both of the nature of the argument and its failure is flawed. Consider instead the possibility that in Groundwork III, Kant is struggling toward something rather different from this, not trying to pull the moral rabbit out of the theoretical hat, but instead seeking a proto-phenomenological grounding of morality: a grounding that begins from first personal felt experiences that already possess moral content, and proceeds to its further practical claims via attentive reflection on these felt experiences. This paper brings this assumption to our reading of Groundwork III, showing that in doing so we acquire a deeper appreciation both of the argument, and the reasons it fails. Kant's argument is practical throughout. And the failure of the argument is the failure of Kant's nascent efforts to provide a new, phenomenological method for the grounding of practical philosophy.     

Serial processing in reading aloud: no challenge for a parallel model

K. Rastle and M. Coltheart (1999) challenged parallel models of reading by showing that the cost of irregularity in low-frequency exception words was modulated by the position of the irregularity in the word. This position-of-irregularity effect was taken as strong evidence of serial processing in reading. This article refutes Rastle and Coltheart's theoretical conclusions in 3 ways: First, a parallel model, the connectionist dual process model (M. Zorzi, G. Houghton, & B. Butterworth, 1998b), produces a position-of-irregularity effect. Second, the supposed serial effect can be reduced to a position-specific grapheme-phoneme consistency effect. Third, the position-of-irregularity effect vanishes when the experimental data are reanalyzed using grapheme-phoneme consistency as the covariate. This demonstration has broader implications for studies aiming at adjudicating between models: Strong inferences should be avoided until the computational models are actually tested.     

The Structural Memory: A network model for human perception of serial objects

Summary The Structural Memory, a network model for human perception of serial objects, such as series, is presented. Our theoretical assumptions originate from the Structural Information (Theory (SIT) (Buffart & Leeuwenberg, 1983; Leeuwenberg, 1969), a theory concerning the perceptible structures in an object and the human preference for one of these structures. A symbolic notation of such a perceptible structure in an object is called a representation. For a given maximum number of symbols we can generate all representations automatically. From this procedure we define G(eneration)-relations between the representations. We also define S(tructure)-relations based upon the structures described by the representations. The representations and relations can be seen as respectively the nodes and links in a network. This network is the basis for the Structural Memory. We therefore assign an activation value to each representation in the network, expressing the strength of the preference for the described structure at a certain moment. By means of a process model we are able to make predictions for the strength of the preference for a perceptible structure in an object. The process is only based upon the network structure, because of a relation found between the preference measure, used in SIT, for a perceptible structure in an object and the number of G- and S-relations of the corresponding representation in the network. It is shown that with two of these process models some experiments by Van Leeuwen and Buffart can be simulated.     

Demand/Withdraw Patterns in Serial Arguments: Implications for Well‐Being

Serial arguing has been linked to relational difficulties. We extend this research by looking at the relationship between demand/withdraw patterns enacted during argumentative episodes and aversive reactions after the episode has ended in romantic relationships (N = 219). We found that individuals who initiated the first confrontation often reported they did so because they were very upset and they initiated a self‐demand/partner‐withdraw pattern that was repeated in subsequent episodes. The self‐demand/partner‐withdraw pattern was positively related to experiencing intrusive thoughts and feelings about the episode, attempts to avoid such thoughts and feelings, a hyperaroused state, and disruption of everyday activities. Individuals who were originally confronted by their partners report that their partners demanded they change and they withdraw, and this pattern was repeated in typical episodes. This pattern is more strongly related to stress than was self‐demand/partner‐withdraw and was equally predictive of attempts to avoid thinking about the event. However, the partner‐demand/self‐withdraw sequence was not strongly related to most of the other aversive episodic reactions.     

Kant,the Third Antinomy and Transcendental Arguments

In this paper, I consider whether a reading of Kant's solution to the Third Antinomy can offer material for devising a new model of transcendental argument. The problem that this form of argument is meant to address is an antinomy between two apparently contradictory claims, q and ¬q, where we seem equally justified in holding both. The model has the following form: p; q is a necessary condition of p; the only justification we have for q is that it is a necessary condition of p; p is justified only in domain X (where X is a domain of objects of cognition); therefore, q is justified only in domain X. Because the argument shows that our justification for q is valid only in X, it also establishes that there is conceptual space to hold ¬q outside of X.     

Serial correlation

Formulas are presented for triserial correlation, quadriserial correlation, etc., and for serial correlation in general. These formulas are based on well-known procedures outlined by Kelley, Peters and Van Voorhis, and others, and involve Pearson's correction for broad categories. The formula for biserial correlation also may be developed following these procedures. The assumptions underlying serial correlation are that the segmented variable is basically continuous and normally distributed, and that all the segments which together would form a whole normal distribution are present.     

Relevance of Context-bound loci to Topical Potential in the Argumentation Stage

In relation to the task of making an expedient selection from the available loci within the topical potential that strategic manoeuvring envisages for the argumentation stage, this paper proposes a version of topics, which is both inspired to the traditional doctrine of topics and consistent with the theoretical framing and the methodological tenets that are proper of modern semantics and current theory of argumentation. The argumentative relevance of communication context in its institutionalised and interpersonal components is brought to light. Three main aspects are focussed on: the strong synergy of the topical and the endoxical components in argument construction, the use of topics in analysis and evaluation of arguments and the heuristic function of topics in the production process. I express to Peter Houtlosser, Corina Andone, Sara Greco Morasso and Andrea Rocci my profound gratitude for their precious suggestions and cordial criticisms.     

Serial dependence in position occurs at the time of perception

Observers perceive objects in the world as stable over space and time, even though the visual experience of those objects is often discontinuous and distorted due to masking, occlusion, camouflage, or noise. How are we able to easily and quickly achieve stable perception in spite of this constantly changing visual input? It was previously shown that observers experience serial dependence in the perception of features and objects, an effect that extends up to 15 seconds back in time. Here, we asked whether the visual system utilizes an object’s prior physical location to inform future position assignments in order to maximize location stability of an object over time. To test this, we presented subjects with small targets at random angular locations relative to central fixation in the peripheral visual field. Subjects reported the perceived location of the target on each trial by adjusting a cursor’s position to match its location. Subjects made consistent errors when reporting the perceived position of the target on the current trial, mislocalizing it toward the position of the target in the preceding two trials (Experiment 1). This pull in position perception occurred even when a response was not required on the previous trial (Experiment 2). In addition, we show that serial dependence in perceived position occurs immediately after stimulus presentation, and it is a fast stabilization mechanism that does not require a delay (Experiment 3). This indicates that serial dependence occurs for position representations and facilitates the stable perception of objects in space. Taken together with previous work, our results show that serial dependence occurs at many stages of visual processing, from initial position assignment to object categorization.     

Healthcare Serial Killers as Confidence Men

Although there is adequate coverage of serial murder in the extant homicide literature, there is a lack of systematic examination of healthcare professionals who serially murder their patients. Using a sample of 58 healthcare serial killers located within North America, South America, and Europe between the years of 1970 and 2010, this study examines notable pre‐offense and post‐offense behaviours of healthcare serial killers. Patterns related to offender aetiology, victim cultivation, crime scene behaviour, and techniques of evasion were explored. The findings from this study suggest that the pre‐offense and post‐offense behaviours of healthcare serial killers can be conceptualised from the theoretical framework of confidence men or ‘con men’. The findings from this study also suggest that healthcare serial killings and offenders who perpetrate them continue to be elusive and warrant additional scholarly attention to reduce their likelihood of engaging in homicide undetected for extended time. Policy implications are also discussed. Copyright © 2013 John Wiley & Sons, Ltd.     

Infant exposure to domestic violence predicts heightened sensitivity to adult verbal conflict

The current study examined whether one‐year‐old infants whose mothers had been victims of domestic violence during the infant's lifetime (exposed; n = 30), compared to those who had not (not exposed; n = 59), would be more likely to experience distress in response to a simulated verbal conflict and whether amount of distress expressed would be influenced by infant temperament. Infants were videotaped during and for five minutes after an experimenter pretended to have a telephone argument. Exposure to domestic violence was related to infant distress following the episode of simulated adult verbal conflict. Temperamental activity, adaptability, and negative mood predicted greater distress only among non‐exposed infants. Findings suggest that while only temperamentally more reactive infants would typically display distress in response to verbal conflict, infants exposed to domestic violence may be likely to display distress in response to verbal conflict regardless of temperament.     

McDowell’s new conceptualism and the difference between chickens,colours and cardinals

McDowell recently renounced the assumption that the content of any knowledgeable, perceptual judgement must be included in the content of the knowledge grounding experience. We argue that McDowell’s introduction of a new category of non-inferential, perceptual knowledge is incompatible with the main line of argument in favour of conceptualism as presented in Mind and World [McDowell, John. 1996. Mind and World. 2nd ed. Cambridge, MA: Harvard University Press]. We reconstruct the original line of argument and show that it rests on the assumption that a specific model of justification, the Comparison Model, must apply to all cases of non-inferential, perceptual knowledge. We then show that the Comparison Model cannot be applied to McDowell’s new category of non-inferential, perceptual knowledge. As a consequence, McDowell is in need of an alternative model of justification and an alternative argument for conceptualism. We propose such an alternative model of justification based on McDowell’s reading of Sellars, but argue that the model only serves to make the need for an alternative motivation for conceptualism more urgent.     

Differential Transfer Benefits of Increased Practice for Constant,Blocked, and Serial Practice Schedules

The effects of practice schedule and amount of practice on the development of the generalized motor program (GMP) and on parameter estimation were investigated. Participants (N = 108) practiced the same relative timing but different absolute durations of a multisegment timing task. Practice schedules (constant, blocked, or serial) were crossed with amounts of practice (low and high). Inclusion of a constant practice condition allowed the authors to investigate the variability of practice prediction. Participants practiced the same proportional durations in a serial or a blocked schedule, which enabled the authors to examine contextual interference. A constant practice schedule enhanced GMP performance when task parameters remained the same, but varied practice schedules were beneficial when task parameters changed. A serial as opposed to a blocked practice schedule was superior when the performance of a task governed by a different GMP was required. Increased practice led to a consolidated task representation that was unavailable for updating.
