Long-term effects of testing on the recall of nontested materials

The isolation paradigm is a staple in the study of distinctiveness and memory. Isolated items are better remembered than non-isolated controls, and the standard interpretation of this effect is that subjective experience of salience recruits extraordinary processing to the isolated item. This interpretation is at odds with data showing an isolation effect when the isolate is not perceived as salient (e.g., von Restorff, 1933). All available research on the early isolation effect has tested memory after a relatively short retention interval. Perhaps the effect of salience on memory in the isolation paradigm would be revealed following longer retention intervals. The experiment reported here examines the effect of isolation following a 48-hour retention interval when the isolate evokes an experience of salience compared to when the isolate does not evoke that reaction. The isolation effect was substantial after the 48-hour delay but equally so for early and late isolation. Salience appears to have nothing to do with the memory processes even at the longer retention intervals.     

All of the above: When multiple correct response options enhance the testing effect

Previous research has shown that multiple choice tests often improve memory retention. However, the presence of incorrect lures often attenuates this memory benefit. The current research examined the effects of “all of the above” (AOTA) options. When such options are correct, no incorrect lures are present. In the first three experiments, a correct AOTA option on an initial test led to a larger memory benefit than no test and standard multiple choice test conditions. The benefits of a correct AOTA option occurred even without feedback on the initial test; for both 5-minute and 48-hour retention delays; and for both cued recall and multiple choice final test formats. In the final experiment, an AOTA question led to better memory retention than did a control condition that had identical timing and exposure to response options. However, the benefits relative to this control condition were similar regardless of the type of multiple choice test (AOTA or not). Results suggest that retrieval contributes to multiple choice testing effects. However, the extra testing effect from a correct AOTA option, rather than being due to more retrieval, might be due simply to more exposure to correct information.     

Adaptive memory: enhanced source memory for animate entities

ABSTRACT

The animacy effect refers to enhanced memory for animate over inanimate items. In two studies, we examined whether this memory advantage generalises to source memory. A multinomial processing tree model was used to disentangle item recognition, source memory, and guessing processes. In Study 1, animate and inanimate words were presented at different spatial locations on the screen. Animacy was associated with enhanced source memory for the spatial locations of the items. In Study 2, pseudowords were associated with animate and inanimate properties. Replicating previous results, the pseudowords were better remembered when they were associated with animate properties than when they were associated with inanimate properties. What is more, participants had enhanced source memory for the association between the pseudowords and the animate properties. The results strengthen the idea that animate items are associated with richer mnemonic representations than inanimate items.     

The effect of self-referencing on memory for different kinds of source information

ABSTRACT

Self-referential processing has been proven to be effective in improving source memory. However, it is unclear whether different types of source information would be consistently enhanced when an item is self-referentially processed. In two experiments, the authors examined the influence of the self (compared with other-referencing and semantic processing) as well as learning intention (incidental/intentional learning) on memory for two types of source information (spatial location and colour) that differ in the amount of cognitive resources they require to be encoded in memory. Results show that self-referencing has enhanced memory for spatial location of words whatever this information is learned intentionally or incidentally, whereas it cannot facilitate memory for the colour of words under the intentional learning condition, nor can it under the incidental condition. These findings suggest that self-referential processing is beneficial in memory improvement but not all-powerful, a source self-reference effect is subject to source information type.     

Transfer-appropriate processing in the testing effect

The testing effect is the finding that taking a review test enhances performance on a final test relative to restudying the material. The present experiment investigated transfer-appropriate processing in the testing effect using semantic and orthographic cues to evoke conceptual and data-driven processing, respectively. After a study phase, subjects either restudied the material or took a cued-recall test consisting of half semantic and half orthographic cues in which the correct response was given as feedback. A final, cued-recall test consisted of the identical cue, or a new cue that was of the same type or different type of cue (semantic/orthographic or orthographic/semantic) as that used for that target in the review test. Testing enhanced memory in all conditions. When the review cues and final-test cues were identical, final recall was higher for semantic than orthographic cues. Consistent with test-based transfer-appropriate processing, memory performance improved as the review and final cues became more similar. These results suggest that the testing effect could potentially be caused by the episodic retrieval processes in a final memory test overlapping more with the episodic retrieval processes in a review test than with the encoding operations performed during restudy.     

Stronger evidence for own-age effects in memory for older as compared to younger adults

Three studies examined whether younger and older adults better recall information associated with their own than information related to another age group. All studies compared young and older adults with respect to incidental memory for previously presented stimuli (Studies 1 and 2: everyday objects; Study 3: vacation advertisements) that had been randomly paired with an age-related cue (e.g., photo of a young or an old person; the word “young” or “old”). All three studies found the expected interaction of participants’ age and age-associated information. Studies 1 and 2 showed that the memory bias for information arbitrarily associated with one's own as compared to another age group was significant for older adults only. However, when age-relevance was introduced in a context of equal importance to younger and older adults (information about vacations paired either with pictures of young or older adults), the memory bias for one's own age group was clearly present for both younger and older adults (Study 3).     

When the face fits: Recognition of celebrities from matching and mismatching faces and voices

The results of two experiments are presented in which participants engaged in a face-recognition or a voice-recognition task. The stimuli were face–voice pairs in which the face and voice were co-presented and were either “matched” (same person), “related” (two highly associated people), or “mismatched” (two unrelated people). Analysis in both experiments confirmed that accuracy and confidence in face recognition was consistently high regardless of the identity of the accompanying voice. However accuracy of voice recognition was increasingly affected as the relationship between voice and accompanying face declined. Moreover, when considering self-reported confidence in voice recognition, confidence remained high for correct responses despite the proportion of these responses declining across conditions. These results converged with existing evidence indicating the vulnerability of voice recognition as a relatively weak signaller of identity, and results are discussed in the context of a person-recognition framework.     

The Concept of the Subject in the Philosophical Hermeneutics of Hans‐Georg Gadamer

Abstract

Certain critics, e.g. Manfred Frank and Hans‐Herbert Kögler, claim that Hans‐Georg Gadamer’s philosophical hermeneutics reduces the individual subject to a mere instrument of history and tradition, the latter reproducing themselves through the subject. However, Gadamer also emphasizes the active role of the subject in shaping and creating history and tradition. In this article I argue that the critics mistakenly emphasize a one‐sided conception of history. By incorporating both active and passive aspects of the subject, Gadamer’s philosophical hermeneutics provides the means by which the individual may be conceived more aptly in an interdependent, dialectical relation to their corresponding historical, cultural, and social context.     

Search for a curvilinear relationship between the sense of coherence and the intensity of PTSD in MVA survivors

Abstract

The relationship between the sense of coherence (SOC) and the intensity of posttraumatic stress disorder (PTSD) was examined in order to determine its nature and to resolve the inconsistencies between (1) a growing body of empirical research that indicates a linear relationship between these variables, and (2) the schema-based theories of PTSD that suggest a curvilinear relationship between cognitions and the intensity of PTSD. In this cross-sectional study an attempt was also made to identify some psychological factors that moderate this relationship. Participants were a sample of 1132 motor vehicle accident (MVA) survivors. The results showed that gender and temperamental predisposition to PTSD constituted moderator variables of the relationship between SOC and the intensity of PTSD. This supported both the empirical evidence on the linear and negative relationship between SOC and the intensity of PTSD and the theories that postulated the curvilinear relationship.     

Confirmatory Factor Analysis of the Posttraumatic Stress Disorder Checklist

Several studies have employed confirmatory factor analysis (CFA) to examine the latent structure of the Posttraumatic Stress Disorder (PTSD) Checklist (PCL; Weathers, Litz, Herman, Huska, & Keane, 1993), a measure that assesses PTSD symptomatology. Findings have failed to support the Diagnostic and Statistical Manual of Mental Disorders (4th ed., text revision [DSM–IV–TR]; American Psychiatric Association, 2000) PTSD model, consisting of reexperiencing, avoidance/numbing, and arousal factors, and no consensus has emerged regarding the best fitting alternative model. Additionally, most studies have utilized homogeneous trauma samples. This study used CFA to examine the PCL factor structure in a sample with exposure to various traumatic events. Superior fit was demonstrated by a model specifying reexperiencing, avoidance, dysphoria, and arousal factors.
