PRESENTISM AND PERSISTENCE

In this paper, I examine various theories of persistence through time under presentism. In Part I, I argue that both perdurantist views (namely, the worm view and the stage view) suffer, in combination with presentism, from serious difficulties and should be rejected. In Part II, I discuss the presentist endurantist view, to see that it does avoid the difficulties of the perdurantist views, and consequently that it does work, but at a price that some may consider as being very high: its ontological commitments to platonic universals and to the substratum theory, that as we shall see follow from the combination of endurantism with presentism, will perhaps not be to everyone's taste.     

PRESENTISM,TRUTH AND SUPERVENIENCE

Truthmaker theory is commonly thought to pose a challenge for presentism. Presentism seems to lack the ontological and ideological resources required to adequately underwrite the truth of propositions concerning the past. That is because if presentism is true, then the past does not exist. According to the standard response to this challenge, the truth of propositions concerning the past supervenes on surrogate entities that ‘stand proxy’ for past things. I argue that in order for the standard response to the truthmaker challenge to succeed these surrogate entities must stand in necessary connections to the past. I go on to argue that because the standard response is already committed to denying the existence of cross‐temporal modal connections of this kind, by its own lights that response is in error. 1     

PRESENTISM, TRUTHMAKERS, AND GOD

The truthmaker objection to presentism (the view that only what exists now exists simpliciter ) is that it lacks sufficient metaphysical resources to ground truths about the past. In this paper I identify five constraints that an adequate presentist response must satisfy. In light of these constraints, I examine and reject responses by Bigelow, Keller, Crisp, and Bourne. Consideration of how these responses fail, however, points toward a proposal that works; one that posits God's memories as truthmakers for truths about the past. I conclude that presentists have, in the truthmaker objection, considerable incentive to endorse theism.     

PRESENTISM: THROUGH THICK AND THIN

Abstract: Presentism is the view that whatever exists presently exists. Without defending Presentism, I argue first that Presentists should be Time -Free Presentists – Presentists whose views do not imply that there exist irreducible times . Second, I argue that Presentists should accept Limited Thick Presentism, the view that 'the present' has some extension and is thereby neither durationlessly thin nor unlimitedly 'thick'. Third, before addressing several objections to Limited Time-Free Thick Presentism [LTFTP], I argue that defenders of LTFTP should accept that 'temporal becoming' involves an overlapping succession of present entities, not a 'skipping' from one set of present entities to the next discrete set.     

COURTSHIP BEHAVIORS, RELATIONSHIP VIOLENCE, AND BREAKUP PERSISTENCE IN COLLEGE MEN AND WOMEN

This study assessed college men's ( n = 85) and women's ( n = 215) courtship persistence behaviors (approach, surveillance, intimidation, mild aggression), which have been linked to stalking, and examined their relations to initial courtship interest, relationship development, and future violence and persistence, while also exploring the role of gender in these relations. Findings showed individuals performed surveillance when initially more interested than the other. Whereas approach behaviors were positively associated with relationship establishment, surveillance and intimidation were negatively associated. As predicted, results showed continuity in persistence and violence over the course of dating relationships. For both genders, courtship mild aggression predicted relationship violence, and persistence behaviors predicted similar persistence at breakup. Early behaviors may foreshadow violence and stalking-related behaviors in both men and women.     

COMPOSITION AND COINCIDENCE

Many philosophers say that the same atoms may compose at once a statue and a lump of matter that could outlive the statue. I reject this because no difference between the statue and the lump could explain why they have different persistence conditions. But if we say that the lump is the statue, it is difficult to see how there could be any human beings. I argue that this and analogous problems about material objects admit only of solutions that at least appear to be radically at odds with our ordinary thinking.     

BEHAVIORAL PERSISTENCE AND VARIABILITY DURING EXTINCTION OF SELF-INJURY MAINTAINED BY ESCAPE

The self-injurious escape behavior of a developmentally disabled adult was treated with extinction. Results of a reversal design showed substantial bursts of responding when extinction was introduced and reintroduced: self-injury remained at a variable and elevated rate for some time before stable, low rates were observed. Data on aggression, a nontarget behavior during both baseline and treatment, showed a pattern similar to that seen for self-injury during the extinction conditions.

EFFECTS OF REINFORCEMENT HISTORY AND INSTRUCTIONS ON THE PERSISTENCE OF STUDENT ENGAGEMENT

We examined the effects of three reinforcement histories on the persistence of task engagement by 2 fourth-grade students using a partially counterbalanced ABCDBCD design. In each condition, an experimenter made four student contacts during the first 2 min of each session (reinforcement baseline), followed by an 8-min extinction period. The reinforcement history that contained an instructional control component produced the greatest persistence in student engagement. The applied relevance of instructional control is discussed.     

CANDIDATE PERSISTENCE AND PERSONALITY TEST PRACTICE EFFECTS: IMPLICATIONS FOR STAFFING SYSTEM MANAGEMENT

Candidates persist in selection settings for numerous reasons, prompting several concerns regarding staffing-system management. Predictors of the propensity to retest and personality test practice effects were investigated among a sample of 15,338 candidates who applied for supervisory positions (and 357 who repeated the selection process) over a 4-year period with a large organization in the service industry. Results reveal greater likelihood of retesting among internal candidates and overall evidence of small-to-moderate personality test practice effects. Compared to passing candidates who retested for various reasons, failing candidates pursued alternative response strategies upon retesting and generated dimension-level practice effects that reached .40 to .60, whereas passing candidates generally replicated their initial profiles. For several subscales, low initial scores were associated with practice effects that exceeded a full standard deviation. Implications for research, practice, and policy are discussed.     

WHAT INFLUENCES BELIEVING CHILD SEXUAL ABUSE DISCLOSURES? THE ROLES OF DEPICTED MEMORY PERSISTENCE, PARTICIPANT GENDER, TRAUMA HISTORY, AND SEXISM

This vignette study investigated factors that influence believing child sexual abuse disclosures. College student participants ( N = 318) in a university human subject pool completed measures about their own trauma history and responded to questions about sexist attitudes. Participants then read vignettes in which an adult disclosed a history of child sexual abuse, rated disclosures for accuracy and believability, and judged the level of abusiveness. Continuous memories were believed more than recovered memories. Men believed abuse reports less than did women, and people who had not experienced trauma were less likely to believe trauma reports. Gender and personal history interacted such that trauma history did not impact women's judgments but did impact men's judgments. Men with a trauma history responded similarly to women with or without a trauma history. High sexism predicted lower judgments of an event being abusive. Hostile sexism was negatively correlated with believing abuse disclosures. Results are considered in light of myths about child sexual abuse.     

FI SCHEDULES AND PERSISTENCE AT GAMBLING IN THE U.K. BETTING OFFICE

This study reports on the direct observations of customers in two U.K. betting offices gambling on horse and dog races. These observations revealed that bets were more frequently placed in the last minutes just prior to the start (the OFF), and that this was caused by high-frequency gamblers (customers who had eight or more bets in a session) consistently placing their bets in the last two minutes prior to the OFF. Low-frequency gamblers (three or fewer bets/session) avoided this time period placing their bets earlier, or after the OFF, i.e., on a later race. It was argued that the betting behavior of the “gamblers” could not be explained either in terms of “skillful betting” or solely in terms of variable ratio schedules but was more adequately accounted for in terms of an interval schedule. It was further suggested that time-based schedules might be of heuristic value in generally understanding persistence at gambling while losing.     

TEMPERAMENTAL ADAPTABILITY,PERSISTENCE, AND REGULARITY: PARENTAL RATINGS OF NORWEGIAN INFANTS AGED 6 TO 12 MONTHS,WITH SOME IMPLICATIONS FOR PREVENTIVE PRACTICE

There is a need for standardized measures of infant temperament to strengthen current practices in prevention and early intervention. The present study provides Norwegian data on the Cameron‐Rice Infant Temperament Questionnaire (CRITQ; J.R. Cameron & D.C. Rice, 1986a), which comprises 46 items and is used within a U.S. health maintenance organization. The CRITQ was filled out by mothers and fathers at 6 and again at 12 months as part of a longitudinal study of mental health during the first years of life (the “Little in Norway” study, N = 1,041 families enrolled; V. Moe & L. Smith, 2010). Results showed that internal consistencies were comparable with U.S. data. The temperament dimensions of persistence, adaptability, and regularity had acceptable or close‐to‐acceptable reliabilities in the U.S. study as well as in this study, and also were unifactorial in confirmatory factor analysis. These dimensions are the focus in this article. Findings concerning parents’ differential ratings of their infants on the three dimensions are reported, as is the stability of parents’ ratings of temperament from 6 to 12 months. In addition, results on the relation between temperament and parenting stress are presented. The study suggests that temperamental adaptability, persistence, and regularity may be relevant when assessing infant behavior, and may be applied in systematic prevention trials for families with infants. The inclusion of concepts related to individual differences in response tendencies and regulatory efforts may broaden the understanding of parent—infant transactions, and thus enrich prevention and sensitizing interventions with the aim of assisting infants’ development.
