We evaluated the discrimination acquisition of individuals with developmental disabilities under immediate and delayed reinforcement. In Experiment 1, discrimination between two alternatives was examined when reinforcement was immediate or delayed by 20 s, 30 s, or 40 s. In Experiment 2, discrimination between 2 alternatives was compared across an immediate reinforcement condition and a delayed...

Pursuing personal goals for delayed rewards (e.g., exercising to improve health) often provides consumers with immediate rewards (e.g., a fun workout) in addition to the delayed rewards they receive. With regard to health and academic goals, we find that attending to the immediate rewards of health and academic activities increases persistence in these activities to a greater extent than attend...

BACKGROUND Brain regions that track value (including the ventral striatum) respond more during the anticipation of immediate than delayed rewards, even when the delayed rewards are larger and equally preferred to the immediate. The anticipatory response to immediate vs. delayed rewards has not previously been examined in association with cigarette smoking. METHODS Smokers (n=35) and nonsmoker...

Motor learning is a process whereby the acquisition of new skills occurs with practice, and can be influenced by the provision of feedback. An important question is what frequency of feedback facilitates motor learning. The guidance hypothesis assumes that the provision of less augmented feedback is better than more because a learner can use his/her own inherent feedback. However, it is unclear...

Although technology has been integrated into vocabulary instruction, to date, few studies have compared whether learning management system (LMS) exercises or online games facilitate better acquisition. The purpose of this study was investigate the Test English for International Communication (TOEIC) lessons plus LMS and TOEIC MultiEx (online games) foster short-term memorization long-term reten...

this case study investigates the effects of robot assisted language learning (rall) on english vocabulary learning and retention of iranian children with high-functioning autism. two groups of three male students (6-10 years old) with high-functioning autism participated in the current study. the humanoid robot nao was used as a teacher assistant to teach english to the rall group. both rall an...

A fundamental motor learning principle conveyed in textbooks is that augmented terminal feedback frequency differentially affects and performance. The guidance hypothesis predicts relative to a reduced of feedback, providing learners with following every practice trial enhances performance but degrades subsequent learning. This change effectiveness for each called reversal effect, because it th...

This study investigated the impact of oral pushed output on the learning and retention of English perfect tenses. During the study, a pre-test was administered to 22 freshmen majoring in English translation. The participants were randomly assigned to two groups. Then, for six sessions both groups received explicit instructions on English perfect tenses. Every session, the experimental group rec...

Developmental differences in recall were investigated as a function of mode of presentation (blocked vs. random), recall condition (cued vs. noncued), and time of recall (immediate vs. delayed). Ninety-six second graders and 96 fourth graders were the subjects, and the stimuli were 20 pictured items from five categories. Data on three dependent variables (item recall, category recall, and clust...

OBJECTIVE To compare intrauterine device (IUD) use at 6 months in women randomized to receive an intrauterine copper contraceptive 1 week compared with 1 month after medical abortion. METHODS We recruited women undergoing medical abortion with mifepristone and misoprostol and choosing the copper IUD for contraception. We randomly assigned participants to "immediate" insertion 1 week after mif...
