Component structure of individual differences in true and false recognition of faces.

Principal-component analyses of 4 face-recognition studies uncovered 2 independent components. The first component was strongly related to false-alarm errors with new faces as well as to facial “conjunctions” that recombine features of previously studied faces. The second component was strongly related to hits as well as to the conjunction/new difference in false-alarm errors. The pattern of loadings on both components was impressively invariant across the experiments, which differed in age range of participants, stimulus set, list length, facial orientation, and the presence versus absence of familiarized lures along with conjunction and entirely new lures in the recognition test. Taken together, the findings show that neither component was exclusively related to discrimination, criterion, configural processing, featural processing, context recollection, or familiarity. Rather, the data are consistent with a neuropsychological model that distinguishes frontal and occipitotemporal contributions to face recognition memory. Within the framework of the model, findings showed that frontal and occipitotemporal contributions are discernible from the pattern of individual differences in behavioral performance among healthy young adults.

Developmental reversals in false memory: A review of data and theory.

Can susceptibility to false memory and suggestion increase dramatically with age? The authors review the theoretical and empirical literatures on this counterintuitive possibility. Until recently, the well-documented pattern was that susceptibility to memory distortion had been found to decline between early childhood and young adulthood. That pattern is the centerpiece of much expert testimony in legal cases involving child witnesses and victims. During the past 5 years, however, several experiments have been published that test fuzzy-trace theory's prediction that some of the most powerful forms of false memory in adults will be greatly attenuated in children. Those experiments show that in some common domains of experience, in which false memories are rooted in meaning connections among events, age increases in false memory are the rule and are sometimes accompanied by net declines in the accuracy of memory. As these experiments are strongly theory-driven, they have established that developmental improvements in the formation of meaning connections are necessary and sufficient to produce age increases in false memory.

Understanding developmental reversals in false memory: Reply to Ghetti (2008) and Howe (2008).

Replies to comments on the current authors' original article (see record 2008-04614-001). S. Ghetti (2008; see record 2008-11487-008) and M. L. Howe (2008; see record 2008-11487-009) presented probative ideas for future research that will deepen scientific understanding of developmental reversals on false memory and establish boundary conditions for these counterintuitive patterns. Ghetti extended the purview of current theoretical principles by formulating hypotheses about how developmental reversals are controlled by the growth of phantom recollection and by the growth of false-memory editing. Some data are available on her hypotheses about phantom recollection, which distinguish phenomenology (vague or vivid) from memory representation (verbatim or gist). Howe introduced alternative theoretical principles that can be traced to the early work of Deese and Underwood. He argued that fuzzy-trace theory is subject to 3 limitations and that his alternative conception makes 3 predictions that contrast with fuzzy-trace theory's predictions. In the current reply, it is shown that the stated limitations do not apply to fuzzy-trace theory, that previously published research runs counter to the 3 predictions, and that the core difference between the 2 approaches is that fuzzy-trace theory is an opponent-processes model whereas the alternative conception is a 1-process model.

Sensitivity reductions in false recognition: A measure of false memories with stronger theoretical implications.

Signal detection analyses of recognition memory indicate that a bias to respond "old" is large for critical words that are centrally related with previously encoded word lists, is small for words that are less related, and is not observed for unrelated words. Also, recognition sensitivity has not been previously shown to differ between those conditions, which has focused debate over how to explain false recognition on the bias differences. In 3 experiments, critical-word sensitivity was lower than sensitivity for other word types, but related-word sensitivity was not lower than sensitivity for unrelated words. Extant models that predict reduced critical-word sensitivity also predict lower sensitivity for related words than for unrelated words. These results provide crucial new constraints on theoretical explanations of false memories. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

What is false memory development the development of? Comment on Brainerd, Reyna, and Ceci (2008).

In this commentary, assumptions about the nature and development of children's false memories as described in a recent article by C. J. Brainerd, V. F. Reyna, and S. J. Ceci (2008; see record 2008-04614-001) are reviewed. Specifically, questions are raised about what drives the development of false memories in fuzzy-trace theory (FTT). Recent studies that challenge a core assumption of FTT, that false memory illusions increase across development as children learn to establish meaningful connections across items (i.e., establish gist), are discussed. An alternative conceptualization of the development of false memory illusions, associative-activation theory (AAT), is presented. AAT provides as viable an account of the development of false memory illusions as does FTT and anticipates a unique set of outcomes that have recently appeared in the developmental literature on false memory illusions.

Processes underlying developmental reversals in false-memory formation: Comment on Brainerd, Reyna, and Ceci (2008).

C. J. Brainerd, V. F. Reyna, and S. J. Ceci (2008; see record 2008-04614-001) reviewed compelling evidence of developmental reversals in false-memory formation (i.e., younger children exhibit lower false-memory rates than do older children and adults) and proposed that this phenomenon depends on the development of gist processing (i.e., the ability to identify and process the semantic theme of word lists, events, etc.). A full understanding of development reversals, however, cannot be achieved without further characterizing the role played by complementary or opposing processes. Suggestions for future research are made from this perspective. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Adaptive memory: Survival processing increases both true and false memory in adults and children.

Research has shown that processing information in a survival context can enhance the information's memorability. The current study examined whether survival processing can also decrease the susceptibility to false memories and whether the survival advantage can be found in children. In Experiment 1, adults rated semantically related words in a survival, moving, or pleasantness scenario. Even though the survival advantage was demonstrated for true recall, there also was an unexpected increase in false memories in the survival condition. Similarly, younger and older children in Experiment 2 displayed superior true recall but also higher rates of false memories in a survival condition. Experiment 3 showed that in adults false memories were also more likely to occur in the survival condition when categorized lists instead of Deese-Roediger-McDermott (DRM)-like word lists were used. In all three experiments, no survival recall advantage was found when net accuracy scores that take the total output into account were used. These findings question whether survival processing is an adaptive memory strategy per se, as such processing not only enriches true recall but simultaneously amplifies the vulnerability to false memories.

Biased recognition of positive faces in aging and amnestic mild cognitive impairment.

We investigated age differences in biased recognition of happy, neutral, or angry faces in 4 experiments. Experiment 1 revealed increased true and false recognition for happy faces in older adults, which persisted even when changing each face’s emotional expression from study to test in Experiment 2. In Experiment 3, we examined the influence of reduced memory capacity on the positivity-induced recognition bias, which showed the absence of emotion-induced memory enhancement but a preserved recognition bias for positive faces in patients with amnestic mild cognitive impairment compared with older adults with normal memory performance. In Experiment 4, we used semantic differentials to measure the connotations of happy and angry faces. Younger and older participants regarded happy faces as more familiar than angry faces, but the older group showed a larger recognition bias for happy faces. This finding indicates that older adults use a gist-based memory strategy based on a semantic association between positive emotion and familiarity. Moreover, older adults’ judgments of valence were more positive for both angry and happy faces, supporting the hypothesis of socioemotional selectivity. We propose that the positivity-induced recognition bias might be based on fluency, which in turn is based on both positivity-oriented emotional goals and on preexisting semantic associations.

Information-theoretic latent distribution modeling: Distinguishing discrete and continuous latent variable models.

Distinguishing between discrete and continuous latent variable distributions has become increasingly important in numerous domains of behavioral science. Here, the authors explore an information-theoretic approach to latent distribution modeling, in which the ability of latent distribution models to represent statistical information in observed data is emphasized. The authors conclude that loss of statistical information with a decrease in the number of latent values provides an attractive basis for comparing discrete and continuous latent variable models. Theoretical considerations as well as the results of 2 Monte Carlo simulations indicate that information theory provides a sound basis for modeling latent distributions and distinguishing between discrete and continuous latent variable models in particular.

Perceptual asymmetries reflect developmental changes in the neuropsychological mechanisms of emotion recognition.

To study how perceptual asymmetries in the recognition of emotion reflect developmental changes in processing affective information, a fused rhyming dichotic word test with positive, negative, and neutral stimuli was administered to adults and children. Results suggested that the hemisphere in which affective information is initially processed affects the strength of perceptual asymmetry and that children's perceptual processing of emotional information is constrained by limited computational resources. Another experiment ruled out effects of volitional shifting of attention to emotional stimuli. These data further confirm that emotional processing involves integration of neural systems across brain regions, including distributed systems that support arousal and recognition. General developmental factors, such as processing capacity, contribute to the coordination of multiple systems responsible for processing emotional information.

False recognition of pictures versus words in Alzheimer's disease: The distinctiveness heuristic.

False recognition of semantic associates can be reduced when older adults also study pictures representing each associate. D. L. Schacter, L. Israel, and C. Racine (1999) attributed this reduction to the operation of a distinctiveness heuristic: a response mode in which participants demand access to detailed recollections to support a positive recognition decision. The authors examined patients with probable Alzheimer's disease (AD) and older adults with this paradigm. Half of the participants studied pictures and auditory words; the other half studied visual and auditory words. Older adults who studied pictures were able to reduce their false alarms compared with those who studied words only. AD patients who studied pictures were unable to reduce their false alarms compared with those who studied words only and, in fact, exhibited trends toward greater false recognition. Implications for understanding semantic memory in AD patients are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

False memory in aging: Effects of emotional valence on word recognition accuracy.

Memory is susceptible to distortions. Valence and increasing age are variables known to affect memory accuracy and may increase false alarm production. Interaction between these variables and their impact on false memory was investigated in 36 young (18-28 years) and 36 older (61-83 years) healthy adults. At study, participants viewed lists of neutral words orthographically related to negative, neutral, or positive critical lures (not presented). Memory for these words was subsequently tested with a remember-know procedure. At test, items included the words seen at study and their associated critical lures, as well as sets of orthographically related neutral words not seen at study and their associated unstudied lures. Positive valence was shown to have two opposite effects on older adults' discrimination of the lures: It improved correct rejection of unstudied lures but increased false memory for critical lures (i.e., lures associated with words studied previously). Thus, increased salience triggered by positive valence may disrupt memory accuracy in older adults when discriminating among similar events. These findings likely reflect a source memory deficit due to decreased efficiency in cognitive control processes with aging. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

The strategic nature of false recognition in the DRM paradigm.

The false memory effect produced by the Deese/Roediger & McDermott (DRM) paradigm is reportedly impervious to warnings to avoid false alarming to the critical lures (D. A. Gallo, H. L. Roediger III, & K. B. McDermott, 2001). This finding has been used as strong evidence against models that attribute the false alarms to a decision process (e.g., M. B. Miller & G. L. Wolford, 1999). In this report, the authors clarify their earlier article and suggest that subjects establish only 2 underlying criteria for a recognition judgment, a liberal criterion for items that seem to be related to 1 of the study list themes and a conservative criterion for items that do not seem to be related. They demonstrate that warnings designed on the basis of these underlying criteria are effective in significantly suppressing the false recognition effect, suggesting that strategic control of the retrieval response does play a role in the DRM paradigm.

Eye movements in reading: Perceptual and cognitive processes.

This article discusses the variability of eye movement behavior. The variability exists between readers, so that the average fixation duration for sonic readers my be around 200 ms and for other readers it may be closer to 300 ms; the average saccade length for some readers may be 6 letter spaces, while for others it may be closer lo 10 letter spaces; and some readers rarely regress while others regress quite frequently. These eye movement characteristics can also be influenced by text difficulty; more difficult text leads to longer fixation durations, shorter saccades, and more regressions. More important than the between reader variability is the within reader variability that exists with each of these measures. The article also discusses research on eye movement during reading.

Phonological priming in auditory word recognition: When both controlled and automatic processes are responsible for the effects.

The phonological priming paradigm provides an interesting methodological tool for studying various components of the speech recognition process. However, concerns about response biases distorting the effects have been repeatedly voiced. This article reviews the main studies on priming and aims to distinguish effects under automatic processes from those under some level of strategic control. Both controlled and automatic processes appear to be responsible for the effects observed in phonological priming experiments. Nonetheless, with careful procedures, it is possible to separate them.

Reaching while calculating: Scheduling of cognitive and perceptual-motor processes.

To address the neglected question of how cognitive and perceptual-motor processes are coordinated, the authors asked participants to move a cursor from one target to another to reveal operators and operands for a running arithmetic task. In Experiment 1 performance on this task was compared with performance on tasks requiring only aiming or only arithmetic. Aiming was faster in the aiming-only task than in the combined task. More importantly, times for steps requiring calculation were equivalent in the combined and arithmetic-only tasks. The results from this and a second experiment suggest that participants slowed their aiming to allow calculations to be completed before subsequent targets were entered. As a whole, the results suggest that cognitive and perceptual-motor processes are coordinated through scheduling. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Memory for gist and detail information in Alzheimer's disease and mild cognitive impairment.

Two experiments examined different forms of gist and detail memory in people with Alzheimer's disease (AD) and those with amnestic mild cognitive impairment (MCI). In Experiment 1, 14 AD, 14 MCI, and 22 control participants were assessed with the Deese-Roediger-McDermott paradigm. Results indicated that false recognition of nonstudied critical lures (gist memory) was diminished in the AD compared with the MCI and control groups; the two latter cohorts performed similarly. In Experiment 2, 14 AD, 20 MCI, and 26 control participants were tested on a text memory task. Results revealed that recall of both macropropositions (gist information) and micropropositions (detail information) decreased significantly in AD and in MCI as compared with control participants. This experiment also revealed that the impairment was comparable between gist and detail memory. In summary, the results were consistent across experiments in the AD but not in the MCI participants. The discrepancy in MCI participants might be explained by differences in the degree of sensitivity of the experimental procedures and/or by the differences in the cognitive processes these procedures assessed.

The cognitive and linguistic foundations of early reading development: A Norwegian latent variable longitudinal study.

The authors present the results of a 2-year longitudinal study of 228 Norwegian children beginning some 12 months before formal reading instruction began. The relationships between a range of cognitive and linguistic skills (letter knowledge, phoneme manipulation, visual–verbal paired-associate learning, rapid automatized naming (RAN), short-term memory, and verbal and nonverbal ability) were investigated and related to later measures of word recognition in reading. Letter knowledge, phoneme manipulation, and RAN were independent longitudinal predictors of early reading (word recognition) skills in the regular Norwegian orthography. Early reading skills initially appeared well described as a unitary construct that then showed rapid differentiation into correlated subskills (word decoding, orthographic choice, text reading, and nonword reading) that showed very high levels of longitudinal stability. The results are related to current ideas about the cognitive foundations of early reading skills. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Latent variable analyses of age trends of cognition in the Health and Retirement Study, 1992-2004.

The present study was conducted to better describe age trends in cognition among older adults in the longitudinal Health and Retirement Study (HRS) from 1992 to 2004 (N = 17,000). The authors used contemporary latent variable models to organize this information in terms of both cross-sectional and longitudinal inferences about age and cognition. Common factor analysis results yielded evidence for at least 2 common factors, labeled Episodic Memory and Mental Status, largely separable from vocabulary. Latent path models with these common factors were based on demographic characteristics. Multilevel models of factorial invariance over age indicated that at least 2 common factors were needed. Latent curve models of episodic memory were based on age at testing and showed substantial age differences and age changes, including impacts due to retesting as well as several time-invariant and time-varying predictors.

Understanding planning ability measured by the Tower of London: An evaluation of its internal structure by latent variable modeling.

The Tower of London (TOL) is a widely used instrument for assessing planning ability. Inhibition and (spatial) working memory are assumed to contribute to performance on the TOL, but findings about the relationship between these cognitive processes are often inconsistent. Moreover, the influence of specific properties of TOL problems on cognitive processes and difficulty level is often not taken into account. Furthermore, it may be expected that several planning strategies can be distinguished that cannot be extracted from the total score. In this study, a factor analysis and a latent class regression analysis were performed to address these issues. The results showed that 4 strategy groups that differed with respect to preplanning time could be distinguished. The effect of problem properties also differed for the 4 groups. Additional analyses showed that the groups differed on average planning performance but that there were no significant differences between inhibition and spatial working memory performance. Finally, it seemed that multiple factors influence performance on the TOL, the most important ones being the score measurements, the problem properties, and strategy use.
