    Behavior Modification

    Excerpt: Behavior modification is learning with a particular intent, namely clinical treatment and change (Ullmann & Krasner, 1965, p. 1). Initially behavior modification referred largely to operant techniques and behavior therapy to respondent techniques. As early as 1965 the terms behavior modification and behavior therapy were used interchangeably (O\u27Donohue & Krasner, 1995). With publication of the journal Behavior Research and Therapy in 1963 and the founding of the Association for the Advancement of Behavior Therapy, behavior therapy became a general term for all of these techniques. Thus behavior therapy will be used in this discussion

    Principles of Behavior Therapy and Behavior Modification (Chapter 5 from The Human Reflex)

    Full text link
    This chapter examines the theoretical aspects of the application of behavioral psychology (technically, the experimental analysis of behavior) to the process of behavior therapy. Beginning with a brief history, we will then discuss the definition of behavior therapy and behavior modification, survey a conception of problem behavior that grows out of the behavioral approach, examine basic approaches to behavior therapy, look at specific behavior change techniques, discuss biblical parallels, and consider several areas of controversy

    Energy Dependence of Jet Quenching and Life-time of the Dense Matter in High-energy Heavy-ion Collisions

    Full text link
    Suppression of high pTp_T hadron spectra in high-energy heavy-ion collisions at different energies is studied within a pQCD parton model incorporating medium induced parton energy loss. The pTp_T dependence of the nuclear modification factor RAA(pT)R_{AA}(p_T) is found to depend on both the energy dependence of the parton energy loss and the power-law behavior of the initial jet spectra. The high pTp_T hadron suppression at s=62.4\sqrt{s}=62.4 GeV and its centrality dependence are studied in detail. The overall values of the modification factor are found to provide strong constraints on the lifetime of the dense matter.Comment: 6 pages in RevTex with 3 postscript figure

    Dilepton distributions at backward rapidities

    The dilepton production at backward rapidities in pAupAu and pppp collisions at RHIC and LHC energies is investigated in the dipole approach. The results are shown through the nuclear modification ratio RpAR_{pA} considering transverse momentum and rapidity spectra. The dilepton modification ratio presents interesting behavior at the backward rapidities when compared with the already known forward ones, since it is related with the large xx kinematical region that is being probed. The rapidity dependence of the nuclear modification ratio in the dilepton production is strongly dependent on the Bjorken xx behavior of the nuclear structure function ratio RF2=F2A/F2pR_{F_{2}}=F_{2}^{A}/F_{2}^{p}. The RpAR_{pA} transverse momentum dependence at backward rapidities is modified due to the large xx nuclear effects: at RHIC energies, for instance, the ratio RpAR_{pA} is reduced as pTp_T increases, presenting an opposite behavior when compared with the forward one. It implies that the dilepton production at backward rapidities should carry information of the nuclear effects at large Bjorken xx, as well as that it is useful to investigate the pTp_T dependence of the observables in this kinematical regime.Comment: 15 pages, 6 figures.
