Animals are commonly trained to perform behaviors during routine husbandry procedures. However, some husbandry procedures have aversive consequences when the real procedure is performed. This commonly results in loss of the trained behavior. The present study assessed whether maintaining the antecedent environmental stimulus conditions between appetitive and aversive outcomes would prevent this effect and, conversely, whether adding a stimulus discrepancy would facilitate this effect. Three domestic rats served as participants in a multiple baseline across participants design with multi-element components. All three rats stopped performing a trained behavior when a discrepant stimulus reliably predicted an aversive outcome. In addition, all three rats continued to perform the same behavior when antecedent environmental stimulus conditions were consistent between aversive and appetitive outcomes. Results are discussed in terms of practical implications for behavior change agents and conceptual implications for learning theory.
Seclusion and restraint have been used in various situations to deal with violent or noncompliant behavior. Because of congressional interest in the use of seclusion and restraint in schools, including passage of H.R. 4247 and the introduction of S. 2860, 111th Congress, first session, this report focuses on the legal issues concerning the use of these techniques in schools, including their application both to children covered by the Individuals with Disabilities Education Act (IDEA) and to those not covered by IDEA.
Children's response to a resistance-to-temptation (RTT) task was investigated under three punishment threat conditions: negative consequence, removing an anticipated reward, and no explicit punishment. Ninety first and second graders participated in the RTT task and seventy-three parents completed the Behavior Assessment System for Children and the Psychopathy Screening Device. As only 4% of children transgressed, results are unclear. Hypotheses tested using approximations of transgression showed no differences in RTT. Children with temperaments characterized by hyperactivity, impulsivity, attention problems, and conduct problems (HIA-CP) had the highest levels of psychopathic traits compared to all others. In addition, spanked children were rated as having significantly more behavioral problems than non-spanked children. Limitations of the current study and suggestions for future research are discussed.
This report discusses the federal mandatory minimum sentencing statutes, that limits the discretion of a sentencing court to impose a sentence that does not include a term of imprisonment or the death penalty. The United States Sentencing Commission's Mandatory Minimum Penalties in the Federal Criminal Justice System (2011) recommends consideration of amendments to several of the statutes under which federal mandatory minimum sentences are most often imposed.
This report provides a brief background information on property and trigger crimes and discusses civil forfeiture, criminal forfeiture, disposition of forfeited assets and constitutional considerations.
This legal sidebar outlines a change in the U.S. interpretation regarding aspects of the United Nations Convention against Torture and Other Cruel, Inhuman or Degrading Treatment or Punishment (CAT); these comments were presented as part of the U.S. periodic report to the U.N. Committee Against Torture.
This thesis attempted a cross-species replication of Bland, et. al., 2018. Human participants went through a computerized, automated shaping procedure that trained them to click on and discriminate between a blue square (SD) and red square (S-delta) on a VR 12 schedule of reinforcement. Three conditions were then presented to the participants consisting of a baseline, punishment, and control condition. In the punishment and control conditions, the SD was replaced by the S-delta or a novel stimulus respectively for 1-second on a VR 5 schedule. With each click, the reaction time and specific object clicked on were recorded. While the present study partially replicated the effect seen in earlier research, our results suggest that, depending on the lens of analysis used, either a punishment or an extinction effect may be causing the results seen.
