Studies in Spaced and Massed Learning: III. Paired-Associate and Serial Learning

An experiment on paired-associate learning was carried out to test Hovland's prediction that spaced practice should be more advantageous than massed if the order of presenting the pairs of nonsense syllables were fixed.

In the results, spaced and massed practice showed little difference in learning efficiency. Hovland's prediction was not confirmed.

In a previous experiment of this series of studies it had been found that spaced practice was more efficient than massed in serial learning when syllables of “low-meaningfulness” value were used; but that there was little difference in efficiency between the two forms of distribution when “high-meaningfulness” syllables were used. The results of the two experiments naturally suggested that, as regards the relative efficiency of spaced and massed practice, paired-associate learning of low-meaningfulness syllables differed from serial learning of similar syllables, but matched serial learning of high-meaningfulness syllables. It seems justifiable to draw the conclusion that the relative efficiency of spaced and massed practice is different in paired-associate and serial learning, not because remote associations can be formed in the one case and not in the other, as Hovland (1939a, 1939b) assumed; but because the organization of the material and the learning processes are different in the two forms of learning.     

Teaching with Massed Versus Interspersed Trials: Effects on Acquisition,Maintenance, and Problem Behavior

The current study evaluated the effects of teaching three programs using massed‐trial teaching (MTT) versus interspersed‐trial teaching (ITT) for three participants diagnosed with autism. Specifically, we compared the (i) rate of response acquisition, (ii) percentage of trials per session with problem behavior, and (iii) number of acquisition targets maintained following mastery. For all three participants, the rate of acquisition was higher under MTT than ITT, and levels of problem behavior were similar in both conditions for each participant. Perhaps the only advantage of ITT over MTT was maintenance of targets at the follow‐up probes for two participants; however, neither approach yielded consistently high levels of correct responding across 2‐, 4‐, and 6‐week follow‐up probes. Collectively, results for these three participants provide some evidence for the additive benefit of MTT over ITT. Copyright © 2014 John Wiley & Sons, Ltd.     

The Effect of Rest Following Massed Practice of Continuous and Discrete Motor Tasks

Theories of the rest-related phenomena of reminiscence and warm-up decrement regard them as independent, being due to different factors. In this study it was found that rest following massed practice of a continuous task increased performance (reminiscence) and rest following massed practice of a discrete task lowered performance (warm-up decrement). The near-zero correlation found between the phenomena indicates that they are indeed independent and task-specific. Implications of the findings for the prediction of the effect of rest, and the fact that much motor learning and performance is task-specific, is discussed.     

Causal Learning: Association Versus Computation

Causal learning enables humans and other animals not only to predict important events or outcomes, but also to control their occurrence in the service of needs and desires. Computational theories assume that causal judgments are based on an estimate of the contingency between a causal cue and an outcome. However, human causal learning exhibits many of the characteristics of the associative learning processes thought to underlie animal conditioning. One problem for associative theory arises from the finding that judgments of the causal power of a cue can be revalued retrospectively after learning episodes when that cue is not present. However, if retrieved representations of cues can support learning, retrospective revaluation is anticipated by modified versions of standard associative theories.     

The Dependence of the form of the Pursuitmeter Learning Function on the Length of the Inter-Practice Rests: II. Theoretical

Three hypotheses derived from an explanation sketch of the ability of some individuals to understand self-embedded (SE) sentences with two embeddings involving Syllogistic reasoning ability were tested with positive results. The data indicate that those individuals who can understand SE sentences with two embeddings will be better able to reason with the use of the Syllogistic form than those who cannot, that those individuals who can reason with the use of the Syllogistic form will be able to understand SE sentences with two embeddings, and that those individuals who cannot reason with the use of the Syllogistic form will not be able to understand SE sentences with two embeddings.     

Women in Egypt: Islamic Rights Versus Cultural Practice

In order to understand the predicament of Muslim women in Egypt, it is necessary to look beyond religion to the strong social and cultural forces, which shape their position in society. Islam is often held responsible for the inequitable and sometimes violent treatment of women in Egypt. However, Islam is unjustifiably blamed for such discriminatory practices against women. The Islamic rights granted to women are, for the most part, just. Women have gained more rights over the years; nevertheless, they continue to suffer, as these rights are often not put into practice, because of social and cultural influences. The Islamic religion is all too often misunderstood and held accountable for the unacceptable treatment of women; whereas in reality, cultural traditions have led to this inequity.     

Comparing the Effects of Unknown-Known Ratios on Word Reading Learning Versus Learning Rates

An extension of G. L. Cates et al. (2003) investigation was conducted to determine if students’ cumulative learning rates would be superior for words read under a traditional drill and practice condition (as they were for spelling in the previous study) than under interspersal conditions of varying ratios of unknown to known words. Participants consisted of three intermediate grade students who were delayed readers. They received a less challenging ratio of unknown to known word (High-P sequencing) interspersal procedure, a more challenging ratio of unknown to known word interspersal training procedure, and a traditional drill and practice procedure in an alternating fashion across several tutoring sessions. Cumulative words read with mastery and cumulative rates of words read with mastery were measured across sessions for each participant under each instructional condition. Findings were consistent with the Cates et al., study revealing that children learn more words per minute of instructional time under the traditional drill and practice condition. These results further support examining instructional efficiency as well as effectiveness when making decisions about selecting and implementing interventions.     

Performance Benefits of Spatially Distributed Versus Stacked Information on Integration Tasks

Understanding the best way to present information has been an issue of interest to many researchers. Regardless of the content of the information, purely physical elements such as spatial organization may also influence performance. Across two studies with 111 undergraduates (78 in Study 1 and 33 in Study 2), we compared spatially distributed (i.e. when information sources are presented side‐by‐side) against stacked displays (i.e. when information sources are sitting on top of one another with only the top source fully visible). A distributed display time advantage was consistently observed. As potential explanations, a memory strategy selection hypothesis was examined along with other procedural alternative explanations.

学习方式的变革:提取促进学习

提取练习效应是指在学习与最终测验之间,等长时间的提取练习与重复学习相比,前者更能促进长时记忆的保持,也称为测试效应。大量研究表明提取测试是一种高效的学习策略,师生却对此认识不足,认为测试只是检测学习效果的评估工具,并不能改变或促进学习。本文主要从提取练习促进学习的认知神经加工机制、提取练习在实践应用中的特点、提高提取练习效应的方法及其在教学实践中的局限四方面梳理了相关研究,为提取练习广泛应用于教学实践提供支持,同时也为师生正确高效利用这一策略提供了参考,使学生获得更高效和持久的学习。     

Observation of Depictive Versus Tracing Gestures Selectively Aids Verbal Versus Visual–Spatial Learning in Primary School Children

Previous research has established that gesture observation aids learning in children. The current study examined whether observation of gestures (i.e. depictive and tracing gestures) differentially affected verbal and visual–spatial retention when learning a route and its street names. Specifically, we explored whether children (n = 97) with lower visual and verbal working‐memory capacity benefited more from observing gestures as compared with children who score higher on these traits. To this end, 11‐ to 13‐year‐old children were presented with an instructional video of a route containing no gestures, depictive gestures, tracing gestures or both depictive and tracing gestures. Results indicated that the type of observed gesture affected performance: Observing tracing gestures or both tracing and depictive gestures increased performance on route retention, while observing depictive gestures or both depictive and tracing gestures increased performance on street name retention. These effects were not differentially affected by working‐memory capacity. Copyright © 2016 John Wiley & Sons, Ltd.     

Attributional Training Versus Contact in Acculturative Learning: A Laboratory Study1

A culture assimilator, a programmed learning technique for teaching about another culture, was combined with behavioral contact to test for the joint effectiveness of the two approaches to acculturative training. A total of 45 White male college students were randomly assigned to five training conditions in a modified Solomon four-group design. Results indicated significant differences between trained and untrained S s on knowledge of Black culture and better behavioral performance (as rated by Black confederates who were blind as to the training conditions) for S s receiving assimilator training followed by contact than the reverse condition. Apparently, the assimilator provides an opportunity to consolidate new attributions prior to their use in a real interaction. The reverse pattern (interaction before the formation of new attributions) is seen as anxiety producing and a test for the role of anxiety in intercultural training was generally positive. Possible implications of the results for cross-cultural training theory and methodology are discussed.     

Massed practice exercises for the elimination of tooth-grinding habits

In 1958, Wolpe described a method for the treatment of excessive tooth-grinding habits based on the principle of massed practice. Wolpe placed his patient on a regimen of exercises in which the patient was required to clench his teeth tightly together for 1 min and then to relax his jaws for 1 min. The patient was instructed to do this five times for one block of trials. Six blocks were to be performed each day for a 2-week period. Wolpe reported the successful elimination of the patient's bruxomania.Ayer and Gale (1969) applied Wolpe's technique in the treatment of a student with a severe bruxing problem and reported that it was effective in eliminating the disorder. Ayer and Levin (1973) felt that the 1-min clenching interval was difficult, if not impossible, for the patient to sustain and eventually determined that 5-sec exercise periods with 5-sec relaxation periods were effective. At a 1-month follow-up they reported treatment had been effective in almost 80% of their patients. Those patients who were not successfully treated were teen-age girls who found the exercise schedule too tedious and time consuming and had failed to perform the exercises.Rugh and Solberg (1974) measured nocturnal masseter muscle electrical activity in fifteen bruxist patients, in an effort to evaluate the effectiveness of massed practice therapy. One group was required to clench their teeth vigorously one hundred times, six times daily. Another group was directed to chew gum for 1$\text{1}\text{2}$ min. six times daily. The placebo group merely clenched the fist and arms one hundred times, six times daily. Nocturnal masseter muscle activity was significantly reduced in both treatment groups as compared to the placebo group, thus permitting the inference that the oral exercises significantly reduced the grinding habits as measured by the electrical activity.Massed practice therapy does appear to be effective for the elimination of tooth-grinding problems. However, the question of long-term effectiveness must still be raised. The present paper reports the results of a year-long follow-up of patients treated with this technique.     

Massed vs. spaced exposure sessions in the treatment of agoraphobia

The differential effects of massed and spaced sessions of exposure in vivo were investigated with 11 agoraphobics in a crossover design. Clients were randomly assigned to one of the following two groups: (a) 10 daily sessions followed by 10 weekly sessions, or (b) 10 once-weekly sessions followed by 10 daily sessions. The results indicated that both massed and spaced sessions of exposure in vivo effected changes in avoidance behavior and subjective anxiety of agoraphobics, massed practice being superior especially with respect to avoidance. It was suggested that the superiority of massed practice is due to the lack of opportunity to engage in avoidance or escape during short inter-session intervals. The relationship between subjective anxiety and avoidance were considered and the differences between clinical and statistical significance were discussed.
