Mode and type of toy elaboration training on kindergartners' retention and transfer learning

The influence of vicarious versus direct learning modes and the type of elaboration training on retention and transfer learning were studied. Thirty-six kindergartners were instructed to visually or verbally elaborate paired toys through direct participation, and 36 classmates learned through observation of their peer model. No improvement in assoviative learning was found due to direct participation: Retention by the model and observer was equivalent for each type of elaboration. The visual quality of the model's toy elaborations produced significant effects on both retention and transfer learning, and visual-verbal modeling increased learning numerically more than visual modeling alone. The results were discussed in terms of a social learning view of observational learning.     

On No-KR tests in motor learning, retention and transfer

In this paper we examine the role of no-knowledge of results (KR) tests in motor learning, retention and transfer. A distinction is drawn between studies of KR and studies of other issues in motor learning that use a No-KR test. Arguments are presented against the currently received position that a No-KR test is an essential protocol to examine motor learning, although a No-KR test is most relevant in the few contexts where the outcome information is not naturally available. Perspectives are provided on the limited though proper role of No-KR tests in motor learning, retention and transfer and these are illustrated through experimental examples. It is proposed that the current restrictive interpretation of KR as only augmented outcome information is narrowing not only the context of KR research but also the study of motor learning in general.     

Tests enhance retention and transfer of spatial learning

Many studies have reported that tests are beneficial for learning (e.g., Roediger & Karpicke, 2006a). However, the majority of studies on the testing effect have been limited to a combination of relatively simple verbal tasks and final tests that assessed memory for the same material that had originally been tested. The present study explored whether testing is beneficial for complex spatial memory and whether these benefits hold for both retention and transfer. After encoding a three-dimensional layout of objects presented in a virtual environment, participants completed a judgment-of-relative-direction (JRD) task in which they imagined standing at one object, facing a second object, and pointed to a third object from the imagined perspective. Some participants completed this task by relying on memory for the previously encoded layout (i.e., the test conditions), whereas for others the location of the third object was identified ahead of time, so that retrieval was not required (i.e., the study condition). On a final test assessing their JRD performance, the participants who learned through test outperformed those who learned through study. This was true even when corrective feedback was not provided on the initial JRD task and when the final test assessed memory from vantage points that had never been practiced during the initial JRD.     

Word acquisition, retention, and transfer: findings from contextual and isolated word training

Successful reading instruction entails not only acquiring new words but also remembering them after training has finished and accessing their word-specific representations when they are encountered in new text. We report two studies demonstrating that acquisition, retention, and transfer of unfamiliar words were affected differentially by isolated word and context training. Materials were individualized to include only those words that average readers in second grade were unable to name in context. Different words were trained in each condition; context training presented words in stories, and isolated word training presented words on flashcards. Together, the studies show that context training promotes word acquisition beyond that experienced from reading words in isolation. Contrary to the prevailing opinion, memory performance for words trained in context and in isolation did not differ; children demonstrated excellent retention over an 8-day interval in both conditions. Finally, transfer was maximized when the congruency between training and testing was high. Therefore, when reading trained words in novel circumstances, the best method of training was mediated by the transfer task employed at test.     

Skill training,retention, and transfer: The effects of a concurrent secondary task

In two experiments, we examined training, retention, and transfer of a duration production skill in a prospective paradigm. Participants were trained with feedback and then were either tested immediately for transfer without feedback or retrained with feedback 1 week later. There were three training and retraining conditions, two involving secondary tasks. Retention of the duration production skill was perfect across the 1-week delay when the secondary task condition was unchanged, but there was no skill transfer when that condition was changed. These findings demonstrate specificity of training, with the assumption that the cognitive operations learned during duration production training incorporate requirements of the secondary task. More generally, this study challenges the current practice in which training conditions often do not match eventual testing conditions.     

Long-term sensitization training primes Aplysia for further learning

Repetitive, unilateral stimulation of Aplysia induces long-term sensitization (LTS) of ipsilaterally elicited siphon-withdrawal responses. Whereas some morphological effects of training appear only on ipsilateral sensory neurons, others appear bilaterally. We tested the possibility that contralateral morphological modifications may have functional significance. Therefore, we examined whether LTS training primes subsequent sensitization. Twenty-four hours after LTS training the effects of brief shock treatment (BST) were examined. BST failed to sensitize animals that had previously received either 4-d control treatment or 4-d ipsilateral LTS training. In contrast, BST did sensitize animals that had previously received 4-d contralateral LTS training, suggesting the presence of a latent trace that primes the animal for further learning.     

Computer-based training versus traditional lecture: Effect on learning and retention

This study investigated the effectiveness of computer-based training (CBT) versus the standard or traditional lecture method. The study was conducted at a large pharmaceutical manufacturing site located in Eastern North Carolina. Subjects were chemical processors in the bulk chemical production division (N=54). All subjects completed a comprehensive hazardous chemicals safety training program, with one treatment group completing the course via a self-directed computer program (n=27) and one completing the course via traditional instructor-led sessions (n=27). Both delivery formats were identical relative to learning objectives and content. Level of learning was assessed via a 33-item pretest and posttest. Subjects were also administered a 33-item retention test one month following completion of the program. Subject biographical data, including educational level, were collected by questionnaire and the Computer Anxiety Index (CAIN) was administered to assess subjects' level of computer anxiety within the CBT group. Satisfaction with training was assessed in both treatment groups. Results indicated 1) both groups demonstrated significant learning following training, 2) there was no significant difference in level of learning between the two groups, 3) retention after one month was significantly higher in the CBT groups, 4) there was no correlation between educational level or computer anxiety and learning, and 5) there was no significant difference between the two groups on satisfaction with the training experience.     

Long-term transfer of learning from books and video during toddlerhood

Television viewing and picture book reading are prevalent activities during toddlerhood, and research has shown that toddlers can imitate from both books and videos after short delays. This is the first study to directly compare toddlers' long-term retention rates for target actions learned from a video or book. Toddlers (N=158) at 18- and 24-months of age saw an experimenter demonstrating how to make a novel three-step toy rattle via a prerecorded video or a picture book. The toddlers' imitation of the target actions was tested after a specific delay (e.g., 2, 4 weeks), and their performance was compared with that of age-matched controls who did not see a demonstration. The 18-month-olds retained the target actions for 2 weeks, exhibiting forgetting at 4 weeks, whereas the 24-month-olds retained the information for up to 4 weeks, exhibiting forgetting at 8 weeks. Retention rates for books and videos did not differ at either age. These findings demonstrate very impressive retention from a brief two-dimensional media demonstration, and they contribute to our overall understanding of long-term memory processes during infancy.     

Following navigation instructions presented verbally or spatially: Effects on training,retention and transfer

Two experiments investigated participants' ability to follow navigation instructions in a situation simulating communication between air traffic controllers and aircrews. A verbal condition, in which instructions were given orally, was compared with a spatial condition, in which commands were shown on a computer display as simulated movements, with the presentation times in the two conditions equated. Retention and transfer were studied a week later when participants performed in either the same or the other condition. In both sessions, participants' initial proportion correct was much higher in the spatial than in the verbal condition, but after three blocks, accuracy in the two conditions was equivalent. Retention was perfect when training and test conditions matched. Training in the verbal condition transferred to the spatial condition but not vice versa. Thus, there is evidence that participants' representations of the movements in the verbal and spatial conditions were not equivalent. Published in 2009 by John Wiley & Sons, Ltd.     

Effect of cognitive demand during training on acquisition, retention and transfer of a postural skill

The study examined whether attentional demands of a concurrent cognitive task during balance training affect the acquisition, retention and transfer of a postural control skill. Single-leg balance was evaluated in 64 volunteers (mean age 24.0 years, SD 3.10 years) while performing either a cognitive task requiring little attention (forward counting) or a highly demanding cognitive task (arithmetic manipulation) following three days of training. Skill retention was evaluated two days following the cessation of training, and transfer was determined by changes in the untrained extremity. Three training sessions induced decreases in mean sway velocity and amplitude variability. Skill retention was enhanced in the group trained under conditions with greater attentional demands, suggesting that diverting attention away from the postural task and allowing learning to involve more automatic processes may enhance the learning of such tasks. Practice induced similar changes in the trained and untrained extremities following both training protocols.     

Adding sound to lipread lists: The effects on serial recall of adding an auditory pulse train and a pure tone to silently lipread lists

These investigations examined subjects’ serial recall of lipread digit lists accompanied by an auditory pulse train. The pulse train indicated the pitch of voiced speech (buzz-speech) of the seen speaker as she was speaking. As a purely auditory signal, it could not support item identification. Such buzz-speech recall was compared with silent lipread list recall and with the recall of buzz-speech lists to which a pure tone had been added (buzz-and-beep lists). No significant difference in overall accuracy of recall emerged for the three types of lipread list; however, there were significant differences in the shape of the serial recall function for the three list types. Recency characterized the silent and the buzz-speech lists, and these lists differed in their varying susceptibilities to a range of speechlike suffixes. By contrast, adding a pure tone to a buzz-speech list (buzz-and-beep) produced little recency and no further recall loss as a function of suffix type. We discuss these effects with reference to the contrast betweensensory-similarity and speechlikeness accounts of auditory recency and suffix effects. Sensory similarity accounts cannot capture the effects reported here, but processing in a speech mode (buzz-and-beep) need not always lead to recency effects like those resulting from clearly heard or lipread lists.     

Training Japanese listeners to identify English /r/and /l/: Long-term retention of learning in perception and production

Previous work from our laboratories has shown that monolingual Japanese adults who were given intensive high-variability perceptual training improved in both perception and production of English /r/-/l/ minimal pairs. In this study, we extended those findings by investigating the long-term retention of learning in both perception and production of this difficult non-native contrast. Results showed that 3 months after completion of the perceptual training procedure, the Japanese trainees maintained their improved levels of performance on the perceptual identification task. Furthermore, perceptual evaluations by native American English listeners of the Japanese trainees’ pretest, posttest, and 3-month follow-up speech productions showed that the trainees retained their long-term improvements in the general quality, identifiability, and overall intelligibility of their English /r/-/l/ word productions. Taken together, the results provide further support for the efficacy of high-variability laboratory speech sound training procedures, and suggest an optimistic outlook for the application of such procedures for a wide range of “special populations.” nt]mis|This work was supported by NIDCD Training Grant DC-00012 and by NIDCD Research Grant DC-00111 to Indiana University.     

Concept attainment, transfer, and retention through observation and rule-provision

The effects of observing a model and of providing a response rule on the learning, transfer, and retention of a dial-reading, numerical concept were studied in 144 third graders. Different Es conducted the immediate learning procedures versus the measurements of retention. No extrinsic reinforcers were promised or dispensed. The children profited both from modeling and from rule-provision, with the strongest learning, transfer, and retention displayed by the group that watched the model and also received the rule summary. Sequence of presenting the sets of retention stimuli (including a series of novel generalization items not previously encountered) did not influence the strength of concept retention 6 weeks after training.
