1. Prenatal alcohol exposure did not affect impulsivity in rats that performed delay or probability discounting tasks
Individuals who fall under the spectrum of the Fetal Alcohol Syndrome have a higher prevalence of several cognitive disturbances, including a greater probability of being diagnosed with attention-deficit hyperactivity disorder (ADHD). Some of these effects, such as hyperactivity and attentional impairments, are already well established in the literature. The

2. Task and delay of reinforcement effects on mathematical questions solution behavior among children with or without ADHD / Efeitos de atraso e tarefa na resolução de problemas matemáticos em crianças com e sem TDAH
The Attention Deficit Hiperativity Disorder (ADHD) has been related to self-control. In behavior analysis, self-control/impulsivity situations have been studied using alternatives differing in reinforcer delay and magnitude. Studies with ADHD children have shown that they have a stronger preference for immediate reinforcers, in comparison to children without

3. Autocontrole e custo da resposta da tarefa programada no atraso de reforçamento
Self-control (SC) may be defined by the choice of the larger longer delayed reinforcement over the smaller short delayed one (IMP), according to Rachlins paradigm. The present study verified the effects of response cost required by a game that could be played during the larger delayed of the self-control alternative. Seven kindergarten children participated

4. Independência funcional entre tatos e mandos: análise de respostas verbais baseadas na seleção de estímulos / Functional Independence between Tacts and Mands: Analysis of Selection-Based Verbal Responses
This project aimed to (a) investigate functional independence between mand and tact selection-based verbal behaviors and (b) investigate variables that could facilitate that a given verbal topography taught in tact could be emitted in mand and vice versa. Four children diagnosed with autism and a child with language delay were participants of the study. To b

5. Efeitos da variação comportamental durante o atraso do reforço sobre a escolha por autocontrole
Studies on self-control include a choice between a small, immediate reinforcer (impulsivity alternative) and a large, delayed reinforcer (self-control alternative). The present study evaluated the effects of the emission of sequences of responses, during the delay, upon choice for self-control. In the BL condition, pigeons were exposed to two choice alternat

6. Self-control: a study on the effect of simultaneous variation of reinforcer magnitude and delay and the possibility of engaging in a distracting activity / Autocontrole: um estudo sobre o efeito da variação simultânea da magnitude e do atraso do reforço e da possibilidade de realização de atividades distrativas
The present study was aimed at analyzing child self-control through the simultaneous variation of magnitude and delay of reinforcement, with and without the possibility of engaging in a distracting activity during the delay of reinforcement. The participants, 11 children between the ages of five to eleven, with and without a diagnosis of ADHD, were presented

7. Comportamento de escolha: um estudo sobre efeito da variação simultânea da magnitude e do atraso do reforço a partir da replicação sistemática de Ferreira (2002) / Choice Behavior: a study on the effect of simultaneous variation of reinforcer magnitude and delay through a systematic replication of Ferreira (2002)
The present experiment is a systematic replication of Ferreira (2002) and aimed to analyze the choice behavior in typical developing children through the simultaneous variation of reinforcer magnitude and delay. The participants, 6 five to six year-old children who studied at a public state pre-school, were exposed to a computer choice task programmed in con

8. Sensitivity of children to variations in reinforcer amount and delay, using toy to reinforcer / Sensibilidade de crianças à variações na magnitude e atraso do reforçamento, usando brinquedo como reforço
The present study investigated if children s choice in a concurrent chained schedule could be controlled by variations on reinforcement delay or magnitude. Six children, ages between 5 and 6 years old, were submitted to a chained VI-VI 15s schedule on the initial ink of the chain. Children responded on a computer screen using a mouse. On the terminal link, r

9. Acquisition Of Cocaine Self-Administration With Unsignaled Delayed Reinforcement In Rhesus Monkeys
Six experimentally naive rhesus monkeys produced 0.01 mg/kg/infusion cocaine by lever pressing under a tandem fixed-ratio 1 differential-reinforcement-of-other-behavior schedule. One lever press initiated an unsignaled 15- or 30-s delay culminating in cocaine delivery. Each press made during the delay reset the delay interval. With two exceptions, respondi
