Data-driven methodology illustrating mechanisms underlying word list recall: Applications to clinical research.

Objective: Word list learning tasks such as the California Verbal Learning Test (CVLT; Delis, Kramer, Kaplan, & Ober, 1987) are widely used to investigate recall strategies. Participants who recall the most words generally employ semantic techniques, whereas those with poor recall (e.g., patients with schizophrenia) rely on serial techniques. However, these conclusions are based on formulas that assume that categories reflect semantic associations, bind strategy to overall performance, and neglect strategy changes over 5 trials. Therefore, we derived novel measures—independent of recall performance—to compute strategies across trials and identify whether diagnosis predicts recall strategy. Method: Participants were included on the basis of performance on the CVLT (i.e., total words recalled over 5 trials). The 50 highest and 50 lowest performers among healthy volunteers (n = 100) and patients with schizophrenia (n = 100) were selected. Novel measures of recall and transition probability were calculated and analyzed by permutation tests. Results: Recall patterns and strategies of patients resembled those of controls with similar performance levels: Regardless of diagnosis, low performers were more likely to recall the first 2 and last 4 items from the list; high performers increased engagement of semantically based transitions across the 5 trials, whereas low performers did not. Conclusions: Cognitive strategy must be considered independent of overall performance before attributing poor performance to degraded learning processes. Our results demonstrate the importance of departing from global scoring techniques, especially when working with clinical populations such as patients with schizophrenia for whom episodic memory deficits are a hallmark feature.

Attentional strategies, attention, and metacognition in Puerto Rican children.

60 2nd-, 5th-, and 8th-grade Puerto Ricans participated in a strategy assessment task and an incidental learning task that provided a measure of attentional performance. Metacognition concerning attention was assessed by asking Ss to predict how much incidental material they would recall. ANOVAs revealed no developmental changes in the use of an efficient attentional strategy, the amount of central recall, the amount of incidental recall, or in metacognitive knowledge. Results differ from a previous study by the 1st author and M. G. Weiss with 60 predominantly White, middle-class Florida children in which attention and strategies became increasingly efficient as a function of age. In comparison to the Florida sample, Puerto Rican 2nd graders' strategies were more efficient and the 8th graders' strategies were less efficient. Attention on the incidental learning task was less selective for the Puerto Rican Ss than the Florida Ss. (9 ref) (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Developmental and individual differences in young children’s use and maintenance of a selective memory strategy.

Children who were 4 to 8 years of age were asked to perform a sort-recall task where only half of the items had to be studied and remembered. Following a baseline trial, children were assigned to 1 of 3 groups and were prompted to use either a sorting or a clustering strategy (experimental groups) or were not prompted at all (control group). Children were seen 2 weeks later and given a new set of items for the transfer-of-training sort–recall phases. Levels of recall and strategy use (sorting, clustering, multiple strategy use) were higher for older children, typical items, sorting prompts, and trials with repeated presentations of test materials. Older children used more strategies than younger children, although even 4-year-olds used more than one strategy when performing the memory tasks. Results of multivariate cluster analyses revealed systematic individual differences, separating low performers from production-deficient children and high performers. Overall, findings show that clustering appears to be an early developing, but less effective strategy, with multiple-strategy use and especially sorting being used more frequently and effectively by older children.

Expertise in professional software design: a process study

Forty professional software designers participated in a study in which they worked on a software design task and reported strategies for accomplishing that task. High performers were identified by a peer-nomination method and performance on a design. Verbal protocol analysis based on a comparison of 12 high and 12 moderate performers indicated that high performers structured their design process by local planning and showed more feedback processing, whereas moderate performers were more engaged in analyzing requirements and verbalizing task-irrelevant cognitions. High performers more often described problem comprehension and cooperation with colleagues as useful strategies. High and moderate performers did not differ with respect to length of experience. None of the differences between the two performance groups could be explained by length of experience.     

Improving fourth-grade students' composition skills: Effects of strategy instruction and self-regulation procedures.

Extending S. Graham and K. R. Harris's (2003) self-regulated strategy development model, this study examined whether self-regulation procedures would increase the effectiveness of a writing strategies training designed to improve 4th graders' (N = 113) composition skills. Students who were taught composition strategies in conjunction with self-regulation procedures were compared with (a) students who were taught the same strategies but received no instruction in self-regulation and (b) students who received didactic lessons in composition. Both at posttest and at maintenance (5 weeks after the instruction), strategy plus self-regulation students wrote more complete and qualitatively better stories than students in the 2 comparison conditions. They also displayed superior performance at a transfer task requiring students to recall essential parts of an orally presented story.

Pretask and on-task adaptive design strategies for selecting number of instances in concept acquisition.

A study with 67 undergraduates investigated design strategies for selecting number of instances needed in a concept learning task. Two strategies used adaptive procedures for the selection process, while a nonadaptive strategy selected instances by number of associated attributes. The data analysis showed that the full adaptive strategy (using pretask and on-task response data) required 25% less learning time and resulted in better posttest performance than the partial adaptive strategy (pretask data only). The partial adaptive strategy was 16% more efficient and demonstrated better performance than the nonadaptive strategy. An effectiveness ratio of 2 to 1 in favor of the full adaptive over the partial and nonadaptive strategies was obtained and illustrates the effect of using on-task data sources for instance selection.

Effects of structure strategy instruction delivered to fifth-grade children using the Internet with and without the aid of older adult tutors.

The authors assessed the impact of using the structure strategy as a base for an intergenerational Internet tutoring program in which older adults, with strategy training, provided Internet-based tutoring for 5th-grade students learning the strategy through an instructional Web site. Students were randomly assigned to 1 of 3 groups: structure strategy with tutors, structure strategy without tutors, and control. Both tutors and children in the structure strategy group with tutors increased strategy use, total and main idea recall, and self-efficacy. Program effects were apparent months after instruction. Posttest performance was related both to careful completion of Web lessons and amount of tutor feedback and content-related questions. Findings have implications for learning from computers, intergenerational tutoring, and reading instruction. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Learning to choose: Cognitive aging and strategy selection learning in decision making.

Decision makers often have to learn from experience. In these situations, people must use the available feedback to select the appropriate decision strategy. How does the ability to select decision strategies on the basis of experience change with age? We examined younger and older adults' strategy selection learning in a probabilistic inference task using a computational model of strategy selection learning. Older adults showed poorer decision performance compared with younger adults. In particular, older adults performed poorly in an environment favoring the use of a more cognitively demanding strategy. The results suggest that the impact of cognitive aging on strategy selection learning depends on the structure of the decision environment.

Assessment of learning in the selection concept-learning task.

Surprisingly little attention has been paid to the nature of learning in the concept-learning task, especially in the selection mode. Following R. Durling and C. Schick (see record 1976-06149-001), learning is analyzed into 2 components, monitoring and strategy learning, using a technique that avoids the confounding of the Durling and Schick method. 330 undergraduates were tested on 4 repetitions of a selection task. A significant degree of learning was observed on a trials-to-solution measure. A partition of trials revealed that most of the improvement consisted of learning to avoid logical errors. A strategy analysis showed that most Ss consistently employed the same strategy across problems. Strategy shifters displayed a small but significant tendency toward more efficient strategies.

Metacognitive differences between skilled and less skilled readers: Remediating deficits through story grammar and attribution training.

Designed a metacognitive intervention program to remediate the failures of 42 4th-grade boys in using metacognitive skills to aid their reading comprehension. The program consisted of 2 components: story grammar training, designed to increase comprehension monitoring; and attribution training, designed to increase awareness of effort in efficient reading. Ss were assigned to 3 groups: 1 group received both components and the other 2 groups each received one component alone. 14 skilled 4th-grade male readers served as a contrast group. Maintenance was assessed through free and probed recall; generalization was assessed through a metareading test and an error detection and correction task. Results indicate that strategy training produced dramatic gains in comprehension. Only Ss receiving attribution training alone showed poorer performance than skilled readers. Partial support was obtained for generalization on the metareading assessment. It is concluded that strategy training improved poor readers' comprehension by providing them with metacognitive skills.

Do performance strategies mediate age-related differences in associative learning?

Associative learning is a basic component of most learning tasks and has been shown to decline with age. The authors examined associative learning for younger and older adults by using a noun-pair task. Interim testing and prior practice on a similar task were the manipulated variables. Participants were encouraged to use an efficient retrieval strategy. Interim tests provided the motivation to learn the information, whereas prior practice on a similar task was presumed to make the task easier. The authors examined these variables both independently and interactively. For younger adults, performance benefited little from prior practice but did benefit from interim testing. For older adults, interim tests were beneficial for development of a retrieval strategy irrespective of prior training. Prior training proved beneficial for development of a retrieval strategy in the absence of interim tests. Thus, task parameters influenced the performance strategy (and learning), especially of older adults.     

Memory training and strategy use in older adults: Results from the ACTIVE study.

Little is known about the long-term effects of memory training in later life on strategy use. Data from the Advanced Cognitive Training for Independent and Vital Elderly (ACTIVE) study (n = 1,401) were used to describe strategy use in a community-dwelling sample of older adults. Strategy clustering scores on verbal list learning tasks of episodic memory were used to test the impact of memory training on strategy use and study longitudinal associations between strategy clustering, memory performance, and everyday functioning. Results suggested that younger, female, white, healthier, and more educated participants show higher strategy clustering scores initially but no characteristics were consistently associated with different trajectories in strategy clustering across all strategy clustering measures together. Memory training had significant immediate effects on all measures of strategy use that were maintained through five years of follow-up. With respect to longitudinal mediation, pre-post training changes in most strategy clustering scores mediate changes in objective memory performance and everyday functioning, implying that strategies can be modified and are closely related to both memory ability and the ability to function independently. This study provides evidence that older adults can be trained to use cognitive strategies, the effects are durable, and strategies are associated with memory and everyday functioning.

Determinants of learning and performance in an associative memory/substitution task: Task constraints, individual differences, volition, and motivation.

The way that cognitive abilities, learning task characteristics, and motivational and volitional processes combine to explain individual differences in performance and learning was investigated. A substitution task was studied over practice, and it was discovered that students used 2 different strategies: a learning strategy focused on memorization and a performance strategy in which students persisted in scanning items. Five experiments investigated strategy differences and the ability and motivational correlates of task performance. First, ability correlates of performance and strategy use were demonstrated. Next, reducing task difficulty increased use of the learning strategy. With periodic memory tests, effective reliance on the learning strategy was increased, and task performance correlations with reasoning ability were lowered. Finally, a combination of self-focus and goal-setting interventions increased both general performance levels and use of the learning strategy. Results are discussed in terms of the goal of developing a more comprehensive understanding of learner differences. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Adaptive flexibility and maladaptive routines in selecting fast and frugal decision strategies.

Decision routines unburden the cognitive capacity of the decision maker. In changing environments, however, routines may become maladaptive. In 2 experiments with a hypothetical stock market game (n = 241), the authors tested whether decision routines tend to persist at the level of decision strategies rather than at the level of options in strategy selection. The payoff structure of the task was changed after 80 decision trials, rendering a new strategy optimal with respect to expected payoff. Whereas most participants detected the appropriate strategy at the beginning of the task, they tended to retain it even when it was no longer optimal. A hint about a possible change had only a small influence on this maladaptive routine; a monetary incentive had none. Switching to a similar but not identical task relaxed the routine, but not much.

Development and evaluation of a learning strategy training program.

Developed an interactive learning strategy system consisting of primary and support strategies. A set of training procedures was also created to facilitate the communication of this system to college-age students. This system was assessed in the context of a 15-wk (2 hrs/wk) learning skills course with 108 Ss. Results indicate that Ss receiving this training exhibited (p?     

Effect of self-efficacy, goals, and task strategies on task performance.

Manipulated self-efficacy and task strategies in the training of 209 undergraduates under high strategy, low strategy, and control conditions. Ss underwent 5 trials and were administered a self-efficacy scale after each trial. Results show that ability, past performance, and self-efficacy were the major predictors of goal choice. Ability, self-efficacy, goals, and task strategies were related to task performance. Self-efficacy was more strongly related to past performance than to future performance but remained a significant predictor of future performance even when past performance was controlled. Self-efficacy ratings for moderate to difficult levels of performance were the best predictors of future performance; a reanalysis of 2 previous goal-setting studies by the first author confirms this finding.

Treating the core deficits of developmental dyslexia: Evidence of transfer of learning after phonologically- and strategy-based reading training programs.

Individuals with dyslexia have difficulty generalizing from word identification training. This study compared 2 forms of word identification training to promote transfer of learning by children with dyslexia. 62 children were randomly assigned to 1 of the training programs or to a study skills control program. One program trained phonological analysis and blending skills and provided direct instruction of letter–sound correspondences; the other trained the acquisition, use, and monitoring of 4 metacognitive decoding strategies. Results provided clear evidence of transfer of learning after treatment of the core reading deficits of these children. Both training approaches were associated with large positive effects, transfer on several measures, and generalized achievement gains. The phonological program resulted in greater generalized gains in the phonological domain and the strategy program in broader-based transfer for real words.

Place and response learning in human virtual navigation: Behavioral measures and gender differences.

Two experiments examined the use of place and response strategies by humans navigating virtual multiple T mazes. In Experiment 1, probe trials revealed that participants commonly used place and response strategies, and place strategies were more frequent early in training, whereas response strategies were more frequent late in training. Compared with women, men learned the correct path through the maze more quickly and developed a more stable route through the maze. In Experiment 2, participants were trained to locate 2 targets. One target required participants to use either a place or response strategy, whereas the other target could be found using either strategy. Accuracy improved faster for place training compared with response training, and women outperformed men in both groups. Probe trials testing transfer of the imposed strategy to the other target found faster transfer for place training than for response training and that women demonstrated faster transfer than men. Accuracy on probe trials was correlated with poor route stability in the place-trained group and with good route stability in the response-trained group, indicating that navigation strategy use may be related to measures of improvement in performance on normal trials.

Relationships of goal orientation, metacognitive activity, and practice strategies with learning outcomes and transfer.

A model of learning transfer that focused on the active role of the learner was developed and tested within a complex decision-making task. The study examined how individual differences, learning strategies, and training outcomes influenced transfer of learning to a more complex task. A sample of 93 undergraduate students participated in a 2-day radar operations study. Hierarchical regression analysis results indicated that mastery orientation was positively related to metacognitive activity of the learner. Metacognitive activity was significantly related to knowledge acquisition, skilled performance at the end of training, and self-efficacy. All 3 of these training outcomes were related to performance on the transfer task. Implications of these findings for research and practice are discussed.

An individual differences analysis of ability and strategy influences: Age-related differences in associative learning.

The relationships among abilities, strategies, and performance on an associative learning task were investigated for young (aged 17 to 34) and older adults (aged 60 to 82). Participants received extensive practice on a noun-pair task in which they could use a visual-scanning strategy or a memory-retrieval strategy. Older adults were more likely to use the scanning strategy. Age differences were reduced when comparisons were made only for participants using a retrieval strategy. Associative memory was predictive of learning on the task, and semantic memory access speed was predictive of practiced performance. Practiced performance on a memory-search task that also required associative learning was predictive of practiced noun-pair performance. Models of ability-performance relationships for skill acquisition are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)
