A Re-evauation of Copied and Recalled Bender-Gestalt Reproductions

This study was designed to compare the copying and recall performances of the Bender-Gestalt of 80 psychiatric patients, falling into five diagnostic groups. To obtain a quantitative measure of the copying performance the Pascal and Suttell scoring system was utilized; however, lack of scoring items for design A and no really satisfactory recall scoring system led to a revised system which resulted in a significantly more discriminating system than Olin and Reznikoff's. Also the study yielded various quantitative and qualitative differences between the five diagnostic groups, the most significant being between the organic and the functional (schizophrenic, depressive, neurotic, and character disorder) sub-groups. Thus performance on the Bender, especially the quantitatively scored recall performance, can be used as a valid diagnostic instrument to differentiate organic from non-organic patients. Yet in each sub-group the various aspects of the Bender performance (copying score, recall score, and number of designs recalled) appeared to be interrelated, while the time element was found to be an independent factor which also did not help to differentiate the diagnostic groups. Performance on the various designs fell into a definite pattern, particularly on the recall phase.     

The Rorschach in the Context of Performance-Based Personality Assessment

Twenty-eight normal and 28 learning disabled children were given the Bender-Gestalt Test under instructional sets of low (standard) attention or high attention. Results failed to support the hypothesis that high attention instructions would lead to differential recall performance of the diagnostic groups. Normal children produced better designs during recall than learning disabled children regardless of instructional set. The evidence suggests that standard Bender instructions should not be altered in an attempt to elicit recall performance differences.     

Interactive presentation in multitrial free recall

This paper explores whether free recall performance and organization can be facilitated using computer-controlled interactive presentation, where stimulus presentation on Trial N+1 depends on the individual subject’s prior recall history. A series of experiments investigated the effects of two types of response-contingent presentation order manipulations and of selective tagging manipulation designed to highlight the presentation of previously nonrecalled items. An initial experiment using 20-word lists showed no differences among groups, due to a ceiling effect. Two subsequent experiments, using longer lists (30 and 40 words), found that recall and subjective organization were increased by selective tagging and by presentation orders that preserved the subject’s prior order of recall. The results demonstrate that subjects’ previous recall histories contain information that can be used to facilitate recall. The potential of other interactive manipulations is discussed.     

The role of phantom recollection in false recall

Although high levels of phantom recollection (illusory vivid experience of the prior "presentation" of unpresented items) have been found for false recognition, little is known about phantom recollection in recall. We examined this issue with Deese/Roediger-McDermott lists using two paradigms: repeated recall and conjoint recall. High levels of phantom recollection were observed with both standard behavioral measures and the parameters of fuzzy-trace theory's dual-recall model. In addition, phantom recollection and the true recollection that accompanies presented items appear to involve different retrieval processes, because they were dissociated by manipulations such as number of recall tests and list strength.     

Lateral word recognition: Effects of unilateral and bilateral presentation, asynchrony of bilateral presentation, and forced order of report

This experiment enquired: (1) whether right visual field (RVF) recognition superiority was greater in bilateral than in unilateral word presentation; (2) whether left field-favouring attentional or recall sets could be induced by presenting left visual field (LVF) words 20 msec prior to RVF words or by instructions to report LVF words prior to RVF words. Results showed: (1) all conditions studied yielded significant RVF superiority; (2) RVF superiority magnitude was significantly greater in bilateral than in unilateral presentation, suggesting the tenability of hypotheses that different mechanisms operate in these conditions; (3) neither earlier delivery nor earlier report of LVF words altered the pattern of RVF superiority in bilateral presentation, the later result demonstrating that differential receptive organization rather than differential recall of the two stimuli is responsible for RVF superiority in bilateral presentation.     

BIP-Bender protocols of learning disabled and regular education students

20 learning disabled and 20 normal elementary school children took the Bender Visual-Motor Gestalt Test twice, once under standard conditions and again using Background Interference Procedure paper. Based on Koppitz's scoring system, the disabled pupils did equally poorly on both modes but performed significantly worse than the normal children when given the standard Bender first. No other differences were found. Other scoring methods are suggested for investigation.     

Effects of drawing on children's item recall

In four experiments, we used item recall tasks to investigate recent claims that young children's event recall can be facilitated by drawing. In Experiments 1 to 3, children of ages 5 to 8 years were tested 4 h after presentation for recall of a set of 25 items that had been presented in groups on a colored, segmented board. In Experiment 1, recall was enhanced by replacement of the objects on the board as they were recalled, but not by drawing them. In Experiments 2 and 3, drawing the board and objects concurrently with or just prior to verbal recall not only failed to facilitate recall, but significantly reduced the number of items reported by 5- to 6-year-olds. In Experiment 4, drawing again impaired recall of items that had been presented as paired associates. Overall, results indicate that under some conditions drawing can impair children's recall rather than facilitate it, as reported in several recent studies.     

Differences in encoding for free recall vs. recognition

Three experiments examined effects of test expectancy on memory for relatively unrelated words. In Experiment I, where preliminary recall or recognition practice was given, both recall and recognition were superior when the subjects expected and had practiced for recall. Free study led to better recall and recognition than paced presentation, but did not interact with test expectancy. Experiment II demonstrated that recall was better for subjects expecting a recall vs. a recognition test in the absence of preliminary practice. In Experiment III all subjects practiced both recall and recognition prior to presentation of the critical list. Study time also was varied. With longer study, recall was better when a recall test was expected, with no test expectancy effect on recognition. There were no appreciable expectancy effects with the short study period. Self-reports and other data suggested that the critical encoding differences produced by test expectancy manipulation were quantitative in nature.     

Vocalization-at-presentation and immediate recall, with varying recall methods

In a free recall situation, written recall is superior to spoken recall, and evidence is adduced suggesting that this may be partly due to the fact that this method of recall permits greater freedom in ordering the material. Evidence is also adduced suggesting that voicing the material at presentation gives superior recall because of a facilitatory effect on storage. This interpretation is supported by the finding that the advantage of vocalizing is not affected by prior knowledge as to whether recall is to be oral or written, and by the suggestion that vocalized lists are more resistant to intra-trial interference than nonvocalized lists. In addition, two earlier observations were confirmed: first, that the advantage of voicing is most marked at fast rates of presentation; and secondly, voicing gives rise to a higher proportion of acoustic errors relative to the number of items incorrectly attempted.     

Explanations of grouping in immediate ordered recall

This article is about grouping in immediate ordered recall. The following findings are reported: (1) grouping a presentation improves recall, even when steps are taken to prevent rehearsal; (2) grouping primarily improves recall of the items adjoining the grouping, creating primacy and recency within groups; and (3) this primacy and recency are found even when single, isolated errors in recall are considered. These results suggest that the effects of grouping cannot be fully explained by rehearsal, chunking, or the number of directions in which an item can be transposed. It is suggested instead that (1) the auditory short-term store contains an unparsed and uncategorized representation that must be parsed and categorized just prior to recall, in a process of recovery; (2) items adjoining the boundary of a presentation are more easily recovered; and (3) grouping creates a boundary within the presentation. To support this explanation, a final experiment demonstrates an interaction between type of stimuli and serial position, with grouping most improving recall of adjoining phonemes.     

Recall criterion does not affect recall level or hypermnesia: A puzzle for generate/recognize theories

Subjects studied a mixed list of 70 words that varied in imagery value and then received three successive tests. Also varied were instructions given to subjects prior to list presentation (imagery or semantic rehearsal) and the type of recall test (standard free recall, an uninhibited-recall procedure in which subjects were encouraged to free associate and to guess while recalling the list, and a forced-recall condition in which they were also told to write a large number of responses to fill the allotted spaces). Recall improved across the three tests in all conditions, but the improvement was greater for high-than for low-imagery words. In addition, hypermnesia (the improved recall across tests) was shown to occur following semantic rehearsal instructions as well as imagery instructions and to occur with low-imagery words, contrary to the imagery hypothesis of the effect. Most importantly, the large variation in recall criterion produced by manipulating instructions at test (as measured by intrusions) did not affect the overall level of correct recall or the magnitude of improvements across tests. Apparently, the assumption of generate-recognize theories that people generate much more information in free recall than they produce (due to a stringent criterion for recognition of the generated material) is false.     

A vasopressin metabolite produces qualitatively different effects on memory retrieval depending on the accessibility of the memory

A vasopressin metabolite, AVP4-9, was injected 1 h prior to retention tests at 1, 6, 11, and 16 days after learning to test the hypothesis that the peptide exerts qualitatively different effects on memory retrieval depending on the accessibility of the memory. The findings provided strong support for this hypothesis: At a retention interval associated with excellent recall in control animals, pretest administration of AVP4-9 (3.0 micrograms/kg) significantly impaired memory, while this same treatment significantly improved recall at an interval associated with poor retention in controls. At retention tests associated with intermediate recall in controls, retrieval was not significantly affected by the peptide treatment. This pattern of results indicates that the peptide treatment is interacting with endogenous changes that correspond to the accessibility of the memory.     

Word priming without awareness: A new approach to circumvent explicit memory contamination

A major methodological limitation arising in the experimental study of implicit memory is that tasks that are characterized as implicit memory tests can be seriously contaminated by the use of covert explicit memory strategies. Given the evidence indicating that brief presentation of words (below the awareness threshold of subjects) can produce semantic priming, we wondered whether rapid visual presentation of primed words might provide an avenue to produce word priming without explicit memory contamination. Normal subjects were tested for word priming on a speeded category membership decision task. Explicit or implicit encoding procedures were used in four different experiments. Results demonstrated that brief presentation of words can indeed offer a means of producing word priming in absence of explicit recognition or recall of the primed words presented during the study phase. They also showed that such priming is equivalent in degree to the priming measured when using either a conventional implicit memory design or an explicit encoding procedure prior to the study of the primes.     

Two modality effects in verbal short-term memory: Evidence from sentence recall

This paper investigates the mechanisms underlying the standard modality effect (i.e., better recall performance for auditorily presented than for visually presented materials), and the modality congruency effect (i.e., better memory performance if the mode of recall and presentation are congruent rather than incongruent). We tested the assumption that the standard modality effect is restricted to the most recent word(s) of the sentences but occurs in both verbatim and gist recall (Experiments 1 and 2), whereas the modality congruency effect should be evident for the rest of the sentence when using verbatim recall (Experiment 3) but not when using gist recall (Experiment 4). All experiments used the Potter-Lombardi intrusion paradigm. When the target word was the most recent word of the sentence, a standard modality effect was found with both verbatim recall and gist recall. When the target word was included in the middle of the sentences, a modality congruency effect was found with verbatim recall but not with gist recall.     

Learning and memory of factual content from narrative and expository text

Background. Research on the presentation of information in narrative versus expository text genres is inconclusive with respect to the question of which is more beneficial for student learning. Aims. We examine the effect of presenting factual content in either narrative or expository genres on student learning. We also consider relevant prior knowledge and working memory capacity (WMC) as potential mediating variables. Sample. Ninety university undergraduate students. Methods. Subjects studied circulatory system content embedded in either narrative or expository texts. Prior circulatory system knowledge, knowledge improvement (learning) and free recall were assessed. Results. Learning and recall did not differ as a function of text genre overall, but did interact with prior knowledge. Learning from the narrative and one expository text was optimal at intermediate levels of prior knowledge, with higher knowledge readers benefiting more from the expository text compared with the narrative text. Prior knowledge was positively related to recall for the expository texts, but unrelated for the narrative text. Subjects' WMC did not predict learning or recall. Conclusions. Results suggest that narrative and expository processing differ with respect to integration of text content with prior knowledge.     

Processing strategies and secondary memory in very rapid forgetting

When a memory test is unexpected, recall performance is quite poor at retention intervals as short as 2–4 seconds. Orienting tasks that change encoding conditions are known to affect forgetting in such “very rapid forgetting” paradigms where people are misled to believe that recall will not be required. We evaluated the hypothesis that differences in forgetting among orienting tasks are attributable to contributions of secondary memory during encoding in two experiments. In Experiment 1, short-term recall performance was inversely related to task demands during encoding, although long-term memory performance was not. Task demands were assessed by making the duration of stimulus presentation dependent on the time required to perform three different orienting tasks. In Experiment 2, we compared performance of that variable-length stimulus presentation to the fixed-length presentation used in most prior research. The results suggested that additional encoding or rehearsal time does not have an appreciable impact on short-term performance. Thus, differences in forgetting appeared to be a function of the contribution of secondary memory rather than a function of the time available to engage in primary memory rehearsal strategies.     

What learning-disabled readers fail to retrieve on verbal dichotic tests: A problem of encoding,retrieval, or storage?

Three theoretical models were assessed as a framework for capturing learning-disabled readers' faulty word retrieval. To this end, learning-disabled and skilled readers were compared on verbal dichotic listening tasks for free recall and cued recall of word lists organized by semantic, phonemic, and structural features. The results indicated that disabled readers were comparable on free recall but were inferior to skilled readers on cued recall. No ability group differences were found for categorical and noncategorical recall intrusions during the cued recall phase. Cued recall performance was further analyzed for individual differences in memory trace structure (via the Tulving & Watkins, 1975, reduction method), ear asymmetry, and the allocation of attention to word features prior to cuing. Results indicated that during the cued recall phase, disabled readers' memory traces were inferior in structure to those of skilled readers, even though the two ability groups produced comparable symmetrical recall patterns for the ear presentations. Further, disabled readers had lower selective attention scores for the interhemispheric processing of information prior to cuing than did skilled readers. Taken together, the results suggest that, prior to cued recall, disabled readers suffer from attentional difficulties during interhemispheric processing, which in turn influences the structural formation of their memory trace.This research was supported by a grant from the U.S. Office of Special Education and Rehabilitative Services. Special appreciation is given to Greelley District IV schools for providing subjects, to Missy Reda and Stephanie Contros for the data collection, and to two anonymous reviewers for their critical comments on a draft of this article.     

Anterograde and retrograde enhancement of 24-h memory by glucose in elderly humans.

The present experiment examined anterograde and retrograde enhancement of memory storage by glucose in elderly humans. Glucose (50 g) or saccharin was administered shortly before or immediately after acquisition of a narrative prose passage. Recall was tested 24 h later. Glucose administration before or after presentation of the material to be learned significantly improved recall 24 h later compared to performance in the saccharin condition. These findings suggest that glucose retroactively enhances memory storage processing in elderly humans and that the enhancement of memory outlasts the transient elevations in blood glucose levels after glucose ingestion.     

The Effects of Positive and Negative Placebos on Human Memory Performances

Two experiments investigated the possible effects of memory-enhancing and memory-impairing placebo capsules (which participants believed to contain active drugs) on participants' performance in a delayed free recall task. In both experiments participants were randomly assigned to either control, positive, or negative placebo conditions, and their memory performance was tested prior to (baseline trial) and after (test trial) the administration of the placebo. Different patterns of results emerged for positive and negative placebos for actual memory performance measures. Whereas negative placebo produces standard placebo effects by impairing both free recall and accuracy scores on test trial, positive placebo does not affect either of these measures (null placebo effect). On the other hand, both positive and negative placebos produce standard placebo effects with respect to participants' self-reports of perceived changes in memory performance: those in the positive placebo group tend to report that the “drug” improved their performance, and those in the negative group tend to report that it impaired it.     

Short term retention of sentences

A series of experiments was performed on the interaction between the short-term retention of sentences and of digits. In Experiment I a digit span method was used whereby subjects were presented with a sentence followed by a sequence of digits and were required either (a) to recall the sentence first and then the digits or (b) to recall the digits followed by the sentence. Under condition (a) prior recall of the sentence reduced the percentage of digit sequences correctly recalled, while under condition (b) retention of the sentence appeared to have no effect on digit recall. This last finding was confirmed in Experiment II, where the sentences varied both in grammatical complexity and length.

In Experiment III the effect of prior recall of a sentence on the recall of digits was found to depend on the type of sentence used. A correlation was observed between the size of this effect and the time taken to recall a sentence. The rate of forgetting suggested by this observation was comparable to that obtained in Experiment IV, where subjects performed an intervening task that did not involve immediate memory for sentences in the interval between the presentation and recall of a six-digit sequence.

It was concluded from these results that the short-term retention of sentences and of lists of items cannot be explained in terms of some general store of limited capacity.
