Unlabelled: Multiple-choice practice tests are beneficial for learning, and students encounter multiple-choice questions regularly. How do students regulate their use of multiple-choice practice testing? And, how effective is students' use of multiple-choice practice testing? In the current experiments, undergraduate participants practiced German-English word pairs. Students started with an initial study trial for each pair.

Retrieval practice is beneficial for both easy-to-learn and difficult-to-learn materials, but scant research has examined students' use of self-testing for items of varying difficulty. In two experiments, we investigated whether students differentially regulate their use of self-testing for easy and difficult items and assessed the effectiveness of students' self-regulated choices. Undergraduate participants learned normatively easy and normatively difficult Lithuanian-English word pair translations.

It is uncontroversial in psychological research that different schedules of practice, which govern the distribution of practice over time, can promote radically different outcomes in terms of gains in performance and the durability of learning. In contrast, in speech-language treatment research, there is a critical need for well-controlled studies examining the impact of the distribution of treatment on efficacy (for reviews, see Cherney, 2012; Warren, Fey, & Yoder, 2007). In this paper, we enumerate key findings from psychological research on learning and memory regarding how different schedules of practice differentially confer durable learning.

This study examined how the distribution and amount of practice affect word retrieval in aphasia as well as how such factors relate to the efficiency of learning. The central hypothesis was that factors that enhance the learning of new knowledge also enhance persistent access to existing, but inconsistently available, word representations. The study evaluated the impact of learning principles on word retrieval by manipulating the timing and amount of retrievals for items presented for naming.

Retrieval practice and spacing are two factors shown to enhance learning in basic psychological research. The present study investigated the clinical applicability of these factors to naming treatment in aphasia. Prior studies have shown that naming treatment that provides retrieval practice (i.

Article Synopsis
  • Interleaved practice is a study method where different types of problems are mixed together, instead of grouped by category, leading to better test performance compared to traditional blocked practice.
  • The study tested two theories, the discriminative-contrast hypothesis and the distributed-practice hypothesis, to understand why interleaved practice is more effective.
  • Results indicated that while standard interleaving improved performance over blocked practice, remote-interleaving (mixing volume problems with unrelated ones) provided even better results, supporting the idea that spaced-out practice enhances learning.

Students rely on their notes to memorise and learn critical course content, and recent studies of note-taking state that most students take notes, citing a survey published in 1974. Over the past four decades, classrooms and note-taking technologies have evolved: students can take notes on electronic devices, and some classes are entirely online. Despite these changes, few studies have investigated their impact on note-taking habits.

Complex span and content-embedded tasks are two kinds of tasks that are designed to measure maintenance and processing in the working memory system. However, a key functional difference between these task types is that complex span tasks require the maintenance of information that is not relevant to the processing task, whereas content-embedded tasks require the maintenance of task-relevant information. The purpose of the present research was to test the hypothesis that more unique variance in inductive reasoning would be explained by content-embedded tasks than by complex span tasks, given that inductive reasoning requires reasoners to maintain and manipulate task-relevant information in order to arrive to a solution.

Research on techniques for enhancing long-term retention has focused almost exclusively on single-session learning conditions. However, even the most potent initial learning manipulations typically do not yield retention levels sufficient for successful performance in many real-world contexts. In contrast, (i.

Although memory retrieval often enhances subsequent memory, Peterson and Mulligan (2013) reported conditions under which retrieval produces poorer subsequent recall-the negative testing effect. The item-specific-relational account proposes that the effect occurs when retrieval disrupts interitem organizational processing relative to the restudy condition. Rawson et al.

When study is spaced across sessions (versus massed within a single session), final performance is greater after spacing. This spacing effect may have multiple causes, and according to the mediator hypothesis, part of the effect can be explained by the use of mediator-based strategies. This hypothesis proposes that when study is spaced across sessions, rather than massed within a session, more mediators will be generated that are longer lasting and hence more mediators will be available to support criterion recall.

Students are expected to learn key-term definitions across many different grade levels and academic disciplines. Thus, investigating ways to promote understanding of key-term definitions is of critical importance for applied purposes. A recent survey showed that learners report engaging in collaborative practice testing when learning key-term definitions, with outcomes also shedding light on the way in which learners report engaging in collaborative testing in real-world contexts (Wissman & Rawson, 2016, Memory, 24, 223-239).

Arnold and McDermott [(2013). Test-potentiated learning: Distinguishing between direct and indirect effects of testing. Journal of Experimental Psychology: Learning, Memory, and Cognition, 39, 940-945] isolated the indirect effects of testing and concluded that encoding is enhanced to a greater extent following more versus fewer practice tests, referred to as test-potentiated learning.

Purpose: The purpose of this article was to examine how different types of learning experiences affect naming impairment in aphasia.

Methods: In 4 people with aphasia with naming impairment, we compared the benefits of naming treatment that emphasized retrieval practice (practice retrieving target names from long-term memory) with errorless learning (repetition training, which preempts retrieval practice) according to different schedules of learning. The design was within subjects.

The study behaviours of students can be assessed from several perspectives, such as what study strategies are used, the total number of hours of study, and the distribution of studying over time. Here, we present the results of a survey study that considered each of these perspectives by asking students to report the what, how much, and when of their study behaviours over the course of a semester. As important, to better understand students' use of study strategies, we also had students report at the beginning of the semester how they intended to study and their beliefs about the effectiveness of a variety of common strategies.

Retrieval practice improves memory for many kinds of materials, and numerous factors moderate the benefits of retrieval practice, including the amount of successful retrieval practice (referred to as the learning criterion). In general, the benefits of retrieval practice are greater with more than with less successful retrieval practice; however, learning items to a higher (vs. lower) criterion requires more time and effort.

In the reading and spelling literature, an ongoing debate concerns whether reading and spelling share a single orthographic lexicon or rely upon independent lexica. Available evidence tends to support a single lexicon account over an independent lexica account, but evidence is mixed and open to alternative explanation. In the current work, we propose another, largely ignored account--separate-but-shared lexica--according to which reading and spelling have separate orthographic lexica, but information can be shared between them.

Concerning age-related effects on cognitive skill acquisition, the modal finding is that older adults do not benefit from practice to the same extent as younger adults in tasks that afford a shift from slower algorithmic processing to faster memory-based processing. In contrast, Rawson and Touron (2009) demonstrated a relatively rapid shift to memory-based processing in the context of a reading task. The current research extended beyond this initial study to provide more definitive evidence for relative preservation of memory-based automaticity in reading tasks for older adults.

The positive effect of delayed retrieval practice on subsequent test performance is robust; by contrast, making delayed judgments of learning (JOLs) encourages covert retrieval but has a minor influence on final test performance. In three experiments, we experimentally established and explored this memory-metamemory paradox. After initial study of paired associates (e.

Recent research has explored the effects of collaborative testing, showing costs and benefits during learning and for subsequent memory. However, no prior research is informative about whether and how students use collaborative testing in real-world contexts. Accordingly, the primary purpose of the current research was to explore the extent to which students use collaborative testing during self-regulated learning.
