Delaying Feedback Is Beneficial, But Only When Curious About The Answer, Kellie Marie Mullaney Jan 2013

Delaying Feedback Is Beneficial, But Only When Curious About The Answer, Kellie Marie Mullaney

Graduate Theses and Dissertations

When students are tested, delaying feedback of the correct answer by a few seconds is more beneficial than providing it immediately (e.g., Brackbill & Kappy, 1962). The current study refers to this effect as the delay-of-feedback benefit. Little is known about the theoretical nature of the delay-of-feedback benefit. The current study investigated the hypothesis that a delay of feedback is beneficial because it allows a learner to anticipate--i.e., look forward to, or devote attentional resources to--the feedback when it arrives. Participants were asked a list of obscure trivia questions. Immediately after answering each question they were asked to indicate ...


Can Interpolated Testing Reduce Retrieval-Induced Forgetting?, Matthew R. Erdman Jan 2013

Can Interpolated Testing Reduce Retrieval-Induced Forgetting?, Matthew R. Erdman

Graduate Theses and Dissertations

Testing can improve retention of tested information (see Roediger & Karpicke, 2006a for review), but it can also impair memory for nontested, related information: an effect termed retrieval-induced forgetting (Anderson, Bjork, & Bjork, 1994). To my knowledge, retrieval-induced forgetting has only been shown in experiments where participants study all exemplars and then perform one retrieval practice phase (see Anderson, 2003; Raaijmakers & Jakab, 2013; Storm & Levy, 2012 for reviews). Researchers have demonstrated that interpolating memory tests during the learning phase can reduce the amount of proactive interference one experiences when one learns new information (Szpunar, McDermott, & Roediger, 2008). In this dissertation, I examined how studying information in multiple blocks rather than one block influenced the buildup of proactive interference. Previous researchers (Szpunar et al., 2008) examined how testing can reduce the buildup of practice interference when all previously studied information was tested. I examined whether testing only a subset of the exemplars in a ...
