Assessing the effectiveness of warnings and the phenomenological characteristics of false memories

The phenomenology of false memories was investigated in three experiments in which participants heard two experimenters read lists of items that were related to critical nonpresented items. In Experiments 1, following a recognition memory test, participants rated the phenomenological characteristics of their memories immediately and after a 48-hour delay. False recognition was prevalent and on several dimensions participants rated their true memories as more vivid than their false memories. In Experiments 2 and 3, following the study phase, participants were warned about the phenomenological differences between true and false memories and were instructed to use this information to avoid reporting nonpresented items. This type of warning was ineffective at reducing false recall (Experiment 2) and false recognition (Experiment 3) relative to unwarned participants. Importantly, the inability of explicit warnings to impact illusory recollections demonstrates that the false memories cannot be attributed simply to a criterion shift.     

Providing information about diagnostic features at retrieval reduces false recognition

In the following study, participants encoded blocked DRM word lists and we varied whether they received information before test about the utility of mnemonic features that potentially discriminate between veridical and false memories. The results of three experiments revealed that this manipulation successfully reduced false recognition of critical theme words. We also found that this manipulation was effective for younger but not older adults. Furthermore, calling attention to the features in test instructions alone was sufficient for reducing false recognition and its effectiveness was not enhanced by also asking participants to rate their phenomenal experience. We argue that providing diagnostic information before test allows participants to establish more accurate expectations about the task and thus improves the efficacy of retrieval and monitoring processes that are subsequently engaged.     

Scoring Biodata: Is it rational to be quasi‐rational?

Five quasi‐rational biodata scales were developed by empirically keying biodata items to predict scores on a measure of the Big Five dimensions of personality. The criterion‐related validities of the quasi‐rational scales were compared to empirical and rational biodata keying methods using supervisory ratings of job performance as the criterion. Empirical keying outperformed the quasi‐rational and rational methods (which had similar validities).     

Effects of working memory load on long‐term word priming

Three experiments assessed the role of verbal and visuo‐spatial working memory in supporting long‐term repetition priming for written words. In Experiment 1, two priming tasks (word stem completion and category‐exemplar production) were included with three levels of load on working memory: (1) without memory load, (2) memory load that involved storing a string of six digits, and (3) memory load that involved storing a graphic shape. Experiments 2 and 3 compared the effects of a verbal (Experiment 2) or a visual (Experiment 3) working memory load at encoding on both an implicit (word stem completion) and an explicit test (cued recall). The results show no effect of memory load in any of the implicit memory tests, suggesting that priming does not rely on working memory resources. By contrast, loading working memory at encoding causes a significant disruptive effect on the explicit memory test for words when the load is verbal but not visual.     

Extending the revelation effect to faces: Haven't we met before?

The revelation effect is an episodic memory phenomenon where participants are more likely to report that they recognise an item when it is judged after an interpolated task than when it is not. Although this effect is very robust, nearly all of the extant research has used verbal or readily verbalisable stimuli. The present two experiments examined whether a revelation effect could be produced with non‐verbal stimuli such as faces. A revelation effect was found in both experiments, for both targets and lures, using faces as stimuli. The findings are integrated into the prevailing empirical frameworks for the revelation effect and face recognition memory.     

Source misattributions and false recognition errors: Examining the role of perceptual resemblance and imagery generation processes

In three experiments, we examine the extent to which participants’ memory errors are affected by the perceptual features of an encoding series and imagery generation processes. Perceptual features were examined by manipulating the features associated with individual items as well as the relationships among items. An encoding instruction manipulation was included to examine the effects of explicit requests to generate images. In all three experiments, participants falsely claimed to have seen pictures of items presented as words, committing picture misattribution errors. These misattribution errors were exaggerated when the perceptual resemblance between pictures and images was relatively high (Experiment 1) and when explicit requests to generate images were omitted from encoding instructions (Experiments 1 and 2). When perceptual cues made the thematic relationships among items salient, the level and pattern of misattribution errors were also affected (Experiments 2 and 3). Results address alternative views about the nature of internal representations resulting in misattribution errors and refute the idea that these errors reflect only participants’ general impressions or beliefs about what was seen.     

Attachment Quality and Psychopathological Symptoms in Clinically Referred Adolescents: The Mediating Role of Early Maladaptive Schema

This study investigated relationships between attachment insecurity, maladaptive cognitive schemas, and various types of psychopathological symptoms in a sample of clinically referred adolescents (N = 82). A mediation model was tested in which maladaptive schemas operated as mediators in the relations between indices of attachment quality and conduct, peer, and emotional problems. Results revealed partial support for the hypothesized mediation effect: the schema domain of disconnection/rejection acted as a mediator in the links between insecure attachment and peer problems and emotional problems. Further analysis of these effects revealed that different types of maladaptive schemas were involved in both types of psychopathology. Altogether, findings suggest that treatment of adolescent psychological problems may need to target the improvement of attachment relationships with peers and parents and the correction of underlying cognitive schemas.     

Negative prospective memory: Remembering not to perform an action

Sometimes it is important to remember not to perform an action, such as remembering to stop taking seasonal allergy medicine when it is no longer needed. Mistakes in accomplishing this goal can involve prospective memory commission errors when individuals mistakenly perform a prospective response. In two experiments, we investigated the role of attentional resources in preventing prospective memory errors to cues that had been associated with a habitual prospective response. In Phase 1 of our experiments, participants performed a prospective memory task during which they either routinely responded to prospective memory cues or responded to these cues one time only. On a subsequent prospective memory task, the participants who had routinely responded to prospective memory cues were vulnerable to commission errors when their attentional resources were taxed. By contrast, dividing attention did not increase commission errors to cues that had not been routinely performed on an earlier task. These data indicate that attentional resources are needed to withhold making habitual prospective memory responses, and they suggest that inhibitory failures are a cause of these prospective memory errors. Finally, we suggest a broader definition of prospective memory that includes remembering to withhold performing actions.     

Commentary on the Functional Creativity Model: Its Application to Understanding Innovative Deception

Cropley, Kaufman, and Cropley (this issue) provide an account of creativity and antisocial behavior, the Functional Creativity Model (FMC), which has utility in the ongoing fight against creative acts of terrorism. Herein, their model is evaluated through its application to understanding the malevolent creativity behind the antisocial use of deception. In particular, malevolent lies that hoodwink victims or unwitting collaborators are considered as part of the planning of terrorists of dastardly deeds. The FMC is also applied to evaluating the counterterrorist prospects of Time Restricted Integrity Confirmation, an innovate method of lie detection that incorporates many of the antiterrorist recommendations of Cropley et al., especially the element of surprise. Recommendations for expanding the FMC are offered.
