Encoding modality can affect memory accuracy via retrieval orientation

Research indicates that false memory is lower following visual than auditory study, potentially because visual information is more distinctive. In the present study we tested the extent to which retrieval orientation can cause a modality effect on memory accuracy. Participants studied unrelated words in different modalities, followed by criterial recollection tests that selectively oriented retrieval toward one study modality at a time. Memory errors were lower when oriented toward visual than toward auditory information, thereby generalizing the modality effect to an explicit source memory task. Moreover, these effects persisted independent of the test presentation modality, indicating that retrieval orientation overrode the potential cuing properties of the test stimulus. An independent manipulation check confirmed that visual recollections were subjectively experienced as more distinctive than auditory recollections. These results suggest that retrieval orientation is sufficient to cause a modality effect on memory accuracy by focusing monitoring processes on the recollection of studied features that are diagnostic of prior presentation.     

Searching from the top down: Ageing and attentional guidance during singleton detection

Previous investigations of adult age differences in visual search suggest that an age-related decline may exist in attentional processes dependent on the observer's knowledge of task-relevant features (top-down processing). The present experiments were conducted to examine age-related changes in top-down attentional guidance during a highly efficient form of search, singleton detection. In Experiment 1 reaction times to detect targets were lower when target features were constant (feature condition) than when target features were allowed to vary between trials (mixed condition), and this reaction time benefit was similar for younger and older adults. Experiments 2 and 3 investigated possible interactions between top-down and bottom-up (stimulus-driven) processes. Experiment 2 demonstrated that search times for both age groups could be improved when targets varied on an additional feature from distractors (double-feature condition) but only when top-down control was available (feature search). In Experiment 3, the availability of top-down guidance enabled both younger and older adults to override the distracting effects of a noninformative spatial location cue. These findings indicate that top-down attentional control mechanisms interact with bottom-up processes to guide search for targets, and that in the context of singleton detection these mechanisms of top-down control are preserved for older adults.     

被遗忘的《古兰经》文化

文化是否能够改变文明，就像人类一样，个人或家族经历中曾被抑制的因素会留下印记，甚至会在当今引发混乱？对上述两种情况，我们是否可以提出假设：以往未解决的冲突和“被遗忘的”，即被抑制的渊源会在当下以不满、冲突和激情的方式重现显现出来？     

Can Computer‐Mediated Interventions Change Theoretical Mediators of Safer Sex? A Meta‐Analysis

The purpose of this study was to conduct a meta‐analysis of computer‐mediated interventions (CMIs) aimed at changing theoretical mediators of safer sex. Meta‐analytic aggregation of effect sizes from k = 20 studies indicated that CMIs significantly improved HIV/AIDS knowledge, d = .276, p < .001, k = 15, N = 6,625; sexual/condom attitudes, d = .161, p < .001, k = 12, N = 5,816; and condom self‐efficacy, d = .186, p < .001, k = 10, N = 3,308. Although assessed in fewer studies, CMIs also significantly increased perceived susceptibility, condom communication, and condom intentions. Effect sizes were found to be of similar magnitude to human‐delivered interventions. Exploratory analysis of moderating influences detected few significant variables. Implications for the development and testing of CMIs are discussed.     

Creative Moments in Relational-Cultural Therapy

SUMMARY

Creative moments in therapy are those occasions when something new and growth-fostering occurs. This article offers three illustrations and a discussion of these characteristics. It is based on a panel discussion held at the Stone Center-Harvard Medical School/Cambridge Hospital “Learning from Women Conference” in April, 2000.
