Effects of Pointing Gestures on Memory for (In)Congruent Stimuli in Children and Young Adults

We investigated whether finger pointing toward picture locations can be used as an external cognitive control tool to guide attention and compensate for the immature cognitive control functions in children compared with young adults. Item and source memory performance was compared for picture‐location pairs that were either semantically congruent (e.g., a cloud presented at the upper half of the screen) or incongruent (e.g., a cloud presented at the lower part of the screen). Contrary to our expectations, pointing had an adverse effect on source memory compared to visual observation only, in both age groups. As expected, superior source memory performance was found for congruent compared to incongruent picture‐locations pairs in both age groups. These findings suggest that pointing toward pictures compared to only viewing may hamper memory, and that congruent picture locations are easier to remember than incongruent ones.     

Unkindest Cuts? Some effects of picture editing on recall of television news information

Research into picture effects on encoding of verbal material has paid little attention to the effects of picture changes. In this experiment, it was found that adults’ recall of the spoken text in a TV news item was impaired by mid‐sentence picture editing. In contrast, both 11‐12 year old and 14‐15 year old children's recall was enhanced by rapid cutting, so long as the accompanying pictures were relevant to the verbal text. Both adults’ and younger children's recall was better with some of the experimentally‐manipulated material than it was with the original broadcast version of the news item. However, 14‐15 year olds performed best with the original version.

It is suggested that viewers are differentially sensitive to unintended production effects and that their processing of verbal information can be disrupted by inappropriately‐timed picture cuts. Research on picture‐text relationships in audio‐visual material needs to take account of picture‐timing, as well as picture content, and television editing procedures may need to be tailored more specifically to suit the intended audience.     

Changes in Memory Prediction Accuracy: Age and Performance Effects

Memory performance predictions are subjective estimates of possible memory task performance. The purpose of this study was to examine possible factors related to changes in word list performance predictions made by younger and older adults. Factors included memory self-efficacy, actual performance, and perceptions of performance. The current study examined the age differences in a sample of 59 older adults (M = 76.83 years) and 52 younger adults (M = 21.19 years) on memory predictions and the accuracy of those predictions for both an immediate and delayed word recall task. While memory self-efficacy did not influence predictions for either group, perceived and actual performance at immediate recall was related to accuracy of predictions at delay for both groups. In addition, there was a significant age-by-time interaction such that older adults became more accurate over time whereas younger adults declined slightly in their prediction accuracy. These findings suggest that older adults are able to make accurate adjustments to their predictions based on both their perceived and actual performance on tasks.     

Deaf children's use of phonological coding: evidence from reading, spelling, and working memory

Two groups of deaf children, aged 8 and 14 years, were presented with a number of tasks designed to assess their reliance on phonological coding. Their performance was compared with that of hearing children of the same chronological age (CA) and reading age (RA). Performance on the first task, short-term recall of pictures, showed that the deaf children's spans were comparable to those of RA controls but lower than CA controls. For the older deaf children, short-term memory span predicted reading ability. There was no clear evidence that the deaf children were using phonological coding in short-term memory when recall of dissimilar items was compared with recall of items with similarly sounding names. In the second task, which assessed orthographic awareness, performance of the deaf children was similar to that of RA controls although scores predicted reading level for the deaf children but not the hearing. The final task was a picture spelling test in which there were marked differences between the deaf and hearing children, most notably in the number of spelling refusals (which was higher for the deaf children in the older group than their RA controls) and the percentage of phonetic errors (which was considerably lower for both groups of deaf children than for any of the hearing controls). Overall these results provide support for the view that deaf children place little reliance on phonological coding.     

Developmentally invariant dissociations in children's true and false memories: not all relatedness is created equal

The role of categorical versus associative relations in 5-, 7-, and 11-year-old children's true and false memories was examined using the Deese-Roediger-McDermott (DRM) paradigm and categorized lists of pictures or words with or without category labels as primes. For true items, recall increased with age and categorized lists were better recalled than DRM lists. For false items, recall increased with age except for picture lists, there were no differences between categorized and DRM lists and no effect of priming, and there were fewer false memories for pictures than words. Like adults, children's false memories are based on associative not thematic relations, whereas their veridical memories depend on both. This new, developmentally invariant dissociation is consistent with knowledge- and resource-based models of memory development.     

Prose-relevant pictures and older learners’ recall of written prose

Research examining the contribution of pictures to young children’s recall of prose materials suggests that pictures can be used to facilitate the recall of information presented in prose passages. Can the positive effects found with young children be extended to older learners? If picture effects are present, are they durable over time? Data collected from two experiments conducted with college students provide evidence for an affirmative answer to both questions.     

Age-related differences on cognitive overload in an audio-visual memory task

The present study aimed to provide evidence outlining whether the type of stimuli used in teaching would provoke differing levels of recall across three different academic age groups. One hundred and twenty-one participants, aged 11–25 years, were given a language-based memory task in the form of a wordlist consisting of 15 concrete and 15 abstract words, presented either visually, acoustically, or a combination of both audio and visual presentation. The study found that the presence of cognitive overload was greater in the older academic age participants than in the younger groups and that as academic experience increased, the visual presentation of the target stimuli produced greater levels of recall than was the case with acoustic and audio-visual presentation. Overall the findings indicate that cognitive overload increases with age, as the younger-age groups were found to have significantly higher levels of word recall in the audio-visual condition than the older groups.     

ADULT AGE DIFFERENCES IN SPEED AND ACCURACY OF MATCHING VERBAL AND PICTORIAL SIGNS

Young (mean age of 19 years) and older (mean age of 69 years) adults participated in a two‐choice, matching‐to‐sample reaction time experiment. Young adults responded more quickly than older adults; all subjects responded more quickly to a verbal standard sign than to a pictorial standard. However, there was an age difference in speed of performance only for those subjects in the stimulus order condition receiving first pictorial standards and then verbal standards. These data are interpreted within a model of dual memory processing systems (verbal and nonverbal). During adulthood there is an increasing tendency for verbal codes to elicit more general associations of both a verbal and a pictorial symbolic nature, while a pictorial code continues to activate only other pictorial stimuli. More generally, the implications of such a model for understanding aging and educational gerontology are discussed.     

RECALL SCORES OF OLD AND YOUNG PEOPLE AS A FUNCTION OF REGISTRATION INTERVALS

The subjects, 24 old (mean age, 69 yr) and 24 young (mean age, 19 yr) people, were given one learning trial on paired associate lists under each of four temporal conditions: (1) 3 sec study (association) interval; (2) self‐paced study interval; (3) self‐paced study interval and 4 sec registration interval; (4) self‐paced study and registration intervals. The response interval for the single recall trial was self‐paced for all conditions. The subject was instructed to use the registration interval to ensure that the association between the paired items was “fixed” in his or her mind. The recall scores of the elderly subjects but not the young subjects improved significantly as a function of the registration interval. The results suggest that with advanced age more time is required for information processing, and specifically for the registration of an association and/or its transfer from primary to secondary memory. The significant improvement of the older subjects from the paced‐study‐interval condition to the self‐paced‐study‐and‐registration‐intervals condition supports the contention that modification of conditions under which the older person is expected to perform can result in substantial performance increments.     

LIST FORMATS IMPROVE MEDICATION INSTRUCTIONS FOR OLDER ADULTS

We conducted a survey to compare a group of older adults’ and a group of younger adults’ beliefs regarding their own and each other's memory abilities. We also asked both age groups to identify items they believed older adults remember well. The survey was returned by 185 older (ages 60‐92) and 184 younger (ages 17‐39) participants. Of the 30 items we generated older adults reported that they would remember 23 better than younger adults would and 7 worse than younger adults would, and younger adults reported that they would remember 12 of the items better and 18 of them worse than older adults. Both age groups also generated many items that they believed older adults remember better than younger adults do. Finally, respondents generated items that they believed adults in their own age group had to remember routinely that adults in the other age group did not. The two groups agreed that older adults would spend more time and have more difficulty learning lines for presentation to an audience than would younger adults. Most of the older adults reported that their memories had changed; most of the younger adults reported that their memories had not changed. The belief that although older adults’ memory is worse than young adults’ they still remember some things better than the young is viewed as a realistic assessment, and implications for future research are discussed.     

Memory for pictures: a life-span study of the role of visual detail

This experiment assessed the effect of the amount of physical detail in pictures on picture recognition memory for 7-year-olds, 9-year-olds, young adults, and older adults over 68. Subjects were presented simple and complex line drawings, factorially combined in a "same-different" recognition test with simple or complex forms of each. For each age group, recognition accuracy was significantly higher for pictures presented in the simple than in the complex form. This effect was due to differences between simple and complex pictures in the correct rejection rate but not the hit rate; subjects were less accurate detecting deletions from changed complex pictures than additions to changed simple pictures. The older adults were no better than chance at correctly rejecting changed complex pictures. Although increasing the presentation duration from 5 sec to 15 sec increased overall accuracy, it did not increase subjects' ability to correctly reject changed complex pictures. Results are interpreted in terms of schematic encoding and storage of pictures. Accordingly, visual information that communicates the central schema of each picture is more likely to be encoded and retained in memory than information that does not communicate this schema.     

ADULT AGE DIFFERENCES IN VOCABULARY ACQUISITION

Both working memory (WM) and existing vocabulary knowledge are used when the meaning of a new word is deciphered in context. Age-related WM deficits and vocabulary strengths suggest that younger and older adults rely on these factors differently. Participants gave definitions for rare, novel words that appeared in short passages. Three measures of each individual difference factor (WM and vocabulary) were administered. Older adults gave more complete definitions for the novel words, had higher vocabulary knowledge test scores, but reduced WM scores compared to younger adults. As predicted, existing vocabulary knowledge contributed more to extracting word meaning from context than did WM for the older adults only.     

BOOK REVIEWS

The relationship between state anxiety and free recall was examined in 74 elderly community‐dwelling adults who had completed a memory improvement program. State anxiety (as measured by the state version of the State Trait Anxiety Inventory) was a significant predictor of recall performance after accounting for age, vocabulary, and study time. State anxiety and age were negatively associated with performance scores, whereas study time and vocabulary were both positively correlated. The evidence suggests that state anxiety should be considered a potential source of variation in verbal learning studies with older adults. The implications of these findings for future research are discussed.

Older Adults' Memory for Verbally Presented Medical Information

Previous research demonstrates that patients typically have difficulty remembering information presented during healthcare consultations. This study examined how older adults learn and remember verbally presented medical information. Healthy older adults were tested for recall in experimental and field settings. Participants viewed a five-minute video of a simulated healthcare consultation and completed free recall, cued recall, and recognition memory tasks. Differences in performance were observed between older and younger adults in the experimental condition on all memory tasks and in the field condition on the cued recall task; older adults tended to remember less information than younger adults. Though older adults had difficulty spontaneously recalling medical information, they were able to take advantage of cues to access verbally learned information. Findings of this study highlight the importance of developing and implementing measures to maximize the abilities of older adults to learn and remember important medical information communicated by healthcare providers.     

On pictures in educational research

A brief sketch of the last 20 years of research on instructional pictures is given with an emphasis on the effects of increasingly analytical approaches, changing conceptions, and changing research questions. Trends in recent picture research, last 10 years, are discussed in greater depth with emphasis on three groups of studies: pictures vs. pictures, pictures vs. words, and pictures plus words. Selected studies in each group are described along with recent theoretical explanations of the pictorial superiority effect and of other pictorial information processing effects. Some of the possible implications of these trends for educational research and practice are mentioned.     

The Development of Clustering in Episodic Memory: A Cognitive-Modeling Approach

Younger children’s free recall from episodic memory is typically less organized than recall by older children. To investigate if and how repeated learning opportunities help children use organizational strategies that improve recall, the authors analyzed category clustering across four study-test cycles. Seven-year-olds, 10-year-olds, and young adults (N = 150) studied categorically related words for a free-recall task. The cognitive processes underlying recall and clustering were measured with a multinomial model. The modeling revealed that developmental differences emerged particularly in the rate of learning to encode words as categorical clusters. The learning curves showed a common pattern across age groups, indicating developmental invariance. Memory for individual items also contributed to developmental differences and was the only factor driving 7-year-olds’ moderate improvements in recall.     

The relationship of deep and surface study approaches on factual and applied test‐bank multiple‐choice question performance

With the advent of online test banks and large introductory classes, instructors have often turned to textbook publisher‐generated multiple‐choice question (MCQ) exams in their courses. Multiple‐choice questions are often divided into categories of factual or applied, thereby implicating levels of cognitive processing. This investigation examined the influence student study approaches have on performance of shallow compared to deep, cognitive process outcomes measured by scores on factual versus application MCQ test bank questions respectively. Fifty‐six introduction to psychology students, aged 18–52 years, completed a modified version of the Revised Two‐Factor Study Process Questionnaire (R‐SPQ‐2F) to access deep or surface study approaches. Mid‐term and final exam MCQ were equally divided between factual and application questions from the textbook publisher test bank. Overall, students performed significantly better on factual MCQ, with older students achieving higher factual and applied scores. Results suggest younger students tend to use a surface approach to study, with reproduction of what was taught to meet minimum requirements. With age statistically controlled, analyses demonstrated that the surface learning approach negatively impacts MCQ performance on questions categorised as factual and applied more than a deep learning approach benefits MCQ performance.     

Working Memory and Children’s Mathematical Skills: Implications for mathematical development and mathematics curricula

This study examined the contributions of the different components of the working memory (WM) model to a range of mathematical skills in children, using measures of WM function that did not involve numerical stimuli. A sample of 148 children (78 Year 3, mean age 8 years and 1 month, and 70 Year 5 pupils, mean age 9 years and 10 months) completed WM measures and age‐appropriate mathematics tests designed to assess four mathematical skills defined by the National Curriculum for England. Visuo‐spatial sketchpad and central executive, but not phonological loop, scores predicted unique variance in children’s curriculum‐based mathematical attainment but the relative contributions of each component did not vary much across the different skills. Subsequently, the mathematics data were re‐analysed using cluster analysis and new performance‐related mathematics factors were derived. All three components of WM predicted unique variance in these performance‐related skills, but revealed a markedly distinct pattern of associations across the two age groups. In particular, the data indicated a stronger role for the visuo‐spatial sketchpad in the younger children’s mathematics performance. We discuss our findings in terms of the importance of WM in the development of early mathematical ability.
