Memory as a Property of Nature

Prerequisite to memory is a past distinct from present. Because wave evolution is both continuous and time-reversible, the undisturbed quantum system lacks a distinct past and therefore the possibility of memory. With the quantum transition, a reversibly evolving superposition of values yields to an irreversible emergence of definite values in a distinct and transient moment of time. The succession of such moments generates an irretrievable past and thus the possibility of memory. Bohm’s notion of implicate and explicate order provides a conceptual basis for memory as a general feature of nature akin to gravity and electromagnetism. I propose that natural memory is an outcome of the continuity of implicate time in the context of discontinuous explicate time. Among the ramifications of natural memory are that laws of nature can propagate through time much like habits and that personal memory does not require neural information storage.     

Memory as a Generative Epistemic Source

It is widely assumed that memory has only the capacity to preserve epistemic features that have been generated by other sources. Specifically, if S knows (justifiedly believes/rationally believes) that p via memory at T2, then it is argued that (i) S must have known (justifiedly believed/rationally believed) that p when it was originally acquired at T1, and (ii) S must have acquired knowledge that p (justification with respect to p/rationality with respect to p) at T1 via a non-memorial source. Thus, according to this view, memory cannot make an unknown proposition known, an unjustified belief justified, or an irrational belief rational–it can only preserve what is already known, justified, or rational. In this paper, I argue that condition (i) is false and, a fortiori , that condition (ii) is false. Hence, I show that, contrary to received wisdom in contemporary epistemology, memory can function as a generative epistemic source.     

Memory retrieval as a self-propagating process

Retrieval of a subset of studied items and the presentation of those items as retrieval cues typically impair retrieval of the other items. Previous research on this self-limiting property of memory retrieval has relied heavily on short retention intervals and similar context between encoding and test. Here, we examined retrieval dynamics also after a prolonged retention interval with different spatial and social context between encoding and test, conditions that mimic people’s remembering in many situations of daily life. For both unrelated word lists and more integrated prose material, we found retrieval and cuing to impair recall of other studied items after a short retention interval, but to improve recall in the prolonged retention interval condition. The results demonstrate that retrieval dynamics depend critically on situation, indicating that quite often in daily life, retrieval may be a self-propagating, rather than a self-limiting process.     

Nietzsche as a Theological Resource

If theology interprets itself onto-theo-logically and God is the highest being, it will have no use for Nietzsche as a resource. Such a theology would demand that God should always make sense to our intellects in their present (finite and fallen) condition — thus subjecting itself to Feuerbach's objections. Nietzsche is a resource, not like Scripture and tradition, but like a prophet whose perspectivisic hermeneutics of finitude illuminates our creation and whose hermeneutics of suspicion illuminates our fall. A number of objections are addressed, including whether this is not bringing coals to the Newcastle of theology practiced at the American Academy of Religion.     

Positive Enactment as a Clinical Resource

Patients regularly make demands for responses that go beyond listening and nonjudgmental exploration. Some contemporary therapists frame these demands as a mobilized developmental longing that can lead to a positive enactment. This article proposes a conceptual framework that allows inquiry into spontaneously emerging positive enactments as a clinical resource.     

Memory as a Self‐Protective Mechanism

The autobiographical memory literature has established that people remember poorly unpleasant, relative to pleasant, life events. We complemented this literature with a theoretical model – the mnemic neglect model – and an experimental paradigm that exerts tight control over the to‐be‐remembered material. Participants recall poorly self‐threatening feedback compared to self‐affirming or other‐relevant feedback – a phenomenon we labeled mnemic neglect. The phenomenon is motivational: it is in the service of self‐protection. The phenomenon is also flexible. Participants can switch from self‐protection (e.g. avoiding negative feedback) to an alternative goal (e.g. striving for feedback with improvement potential), when circumstances call for it such as when the feedback is provided by a close other rather than a stranger. Finally, self‐threatening feedback may be forgotten, but it is not lost: the mnemic neglect effect is not obtained in recognition recall.     

Analysis of Memory as a Feedforward Control Mechanism

The properties of memory as a feedforward control mechanism of perception and motion have been investigated by requiring Ss to project in active space-time an observed stimulus wave pattern. Memory error was measured under conditions in which the visual feedback of the memory response was delayed and interrupted (sampled) at five time magnitudes (0.0, 0.2, 0.4, 0.6, and 0.8 sec). In addition, memory performance was measured under conditions of temporal pacing by an auditory clock and no such pacing. Results confirmed the hypotheses that memory error in projecting an observed stimulus target on a space-time basis would be improved by time pacing and systematically degraded by variable magnitudes of feedback delay and interruption of the projected movement patterns. The results indicate that memory, as well as learning, may be organized on a spacetime basis and that the critical time factors are related to feedback-and feedforward-control timing in temporally spanning past response and experience through learning and in projecting such space-time control of acquisition in-memory.     

Memory as a cognitive representation of post-traumatic growth

Background and objectives: Previous studies on traumatic memory have primarily focused on the correlation between traumatic symptoms and negative memories, often utilizing the directed forgetting paradigm. Different from previous research, this study aimed to examine the correlation of post-traumatic growth (PTG) and positive memories, with the objective to explore the directed forgetting effect of positive material and its relationship with PTG.

Design: A 2 (PTG level: high vs. low)?×?2 (instructions: To-Be-Forgotten vs. To-Be-Remembered)?×?3 (word valence: positive vs. neutral vs. trauma related) mixed-factorial-designed experiment was applied.

Methods: Participants were 46 senior high-school students who had survived in the Sichuan earthquake in 2008. Participants were divided into two groups based on PTG: high (n?=?24) and low (n?=?22). Both groups were presented, and asked to recall, three word categories (positive, trauma-related, and neutral) following the directed forgetting paradigm.

Results: A mixed-design factorial ANOVA yielded a significant interaction effect of word valence and PTG group, with the high-PTG group recalling more positive words than the low-PTG group.

Conclusions: This was the first study to identify a key cognitive process of PTG by integrating the directed forgetting paradigm into an investigation of PTG.     

Controllable Oddness as a Resource in Creativity

Religion, although often a powerful source of comfort, can also become a source of sadness, stress, or confusion in people's lives. Given the many demonstrated links between religiosity and well-being, some people may turn to religion with the primary aim of seeing how religion might help or profit them. Granted, religious belief and involvement can provide many benefits, including social support, a sense of meaning, purpose, and direction for one's life, an environment that fosters the development of virtue, and perhaps even a close, personal relationship with God. However, problems can arise in any of these areas, creating stumbling blocks that can create personal distress and weaken religious interest or commitment. This article considers four major stumbling blocks associated with religion: interpersonal strains, negative attitudes toward God, inner struggles to believe, and problems associated with virtuous striving.     

Coding for Short-Term Memory as a Function of Age

Twenty-one young (), 21 middle-aged (), and 21 old () female volunteers viewed letter sequences of 12 letters each and were required to recall the letters in exactly the same order as they saw them. In half of the sequences the letters could not be coded into meaningful units, while in the other half the letters could be chunked into three complete four-letter words. The findings indicated that the age groups did not differ from each other in the low-code condition, but that with the high-code sequences the old subjects performed significantly more poorly than either the young or middle-aged subjects. These findings suggest an age-related deficit in the coding of sequentially ordered material.     

Memory for Words as a Function of Spelling Transparency

The authors investigated the impact of spelling transparency on memory for words written in Persian orthography. Adult Persian university students (N = 212) performed in a memory recall experiment on 160 monosyllabic words printed on 8 cards (20 on each card) manipulated for spelling transparency, frequency, and imageability. Each card was presented randomly to the participants and they were asked to read the words aloud as quickly as possible. After reading each card, the participants were asked to engage in a digital addition task for 20 s (as a distracter), which was immediately followed by a request to write down as many words as possible from the cards in 40 s. No significant difference was found in the time to name aloud the opaque and transparent words, whereas on the memory recall task there were main effects for spelling, frequency, and imageability and significant 2-way and 3-way interactions. The effects were greatest for transparent spellings when they were of high frequency and high imageability or low frequency and low imageability. The implications of these findings are discussed.

Beliefs about Memory as a Mediator of Relations between Metacognitive Beliefs and Actual Memory Performance

The goal of the present study was to investigate relationships between personal beliefs about memory, metacognitive beliefs, and actual memory performance. One hundred thirty-seven participants' (aged 20 to 60 years) metacognitive beliefs were measured using the Metacognition Questionnaire (MCQ-30), memory beliefs were measured using the Personal Beliefs about Memory Instrument (PBMI), and an episodic memory task was used to measure actual memory performance, memory predictions, and postdictions. Younger adults had lower scores on the positive beliefs subfactor of the MCQ-30, higher scores on retrospective change and control subfactors of the PBMI, and outperformed middle-aged adults on recall and recall postdiction. Path analysis showed that individuals' beliefs about memory mediate the relationship between metacognitive beliefs and actual memory performance. Specifically, low lack of confidence (or less worry) in one's own memory and attentional capabilities was related to higher memory performance and positive personal beliefs regarding specific memory ability mediated relationship.     

情节记忆中的前摄干扰：神经心理药物学及计算认知建模研究

记忆障碍患者的前摄干扰敏感性显著上升, 但其认知机制仍不清楚。结合神经心理药物学实验和计算认知建模方法对这一问题进行了研究。实验为被试内、双盲设计, 由健康成年人进行两次词对任务的学习, 间隔一周, 两次测试中或注射0.03 mg/kg体重咪唑安定或注射相同浓度的生理盐水。学习过程中及学习结束后进行测试, 要求被试根据线索词回忆靶词。实验结果发现, 注射咪唑安定可引起情节记忆的短时下降, 两种注射条件下均呈现明显的前摄干扰; 与生理盐水条件相比, 注射咪唑安定时引起的前摄干扰显著较高。基于SAC (Source of Action Confusion)的计算认知建模结果较好地拟合了实验数据。这一结果提示, 编码困难可能是记忆障碍患者前摄干扰敏感性较高的主要原因。     

Total Recall: Treating Chronic Mental Illness as a Memory

The ideas outlined in this paper developed from three separate strands of my work as a therapist treating older people. Firstly, I was concerned with reducing the number of patients not benefiting from therapy. In keeping with Pinquart et al.'s (Am J Psychiatry 163:1493–1501, 2006) recent meta-analytic survey concerning the use of psychotherapy and medication, 50% of the depressed patients treated by my team failed to respond adequately. Secondly, the ideas grew out of my attempts to determine why different therapies with older people have often been shown to have equivocal beneficial impacts (Davies and Collerton, J Ment Health 6:335–344, 1997). Thirdly, I was interested in integrating the relevant neuropsychological features, particularly memory, into my therapeutic work. These three strands have led me to propose a pan-theoretical model of distress based on memory functioning and existing information processing perspectives (Teasdale and Barnard, Affect, cognition and change: Remodelling depressive thought, 1993; Power and Dalgleish, Behav Cogn Psychother, 27:129–142, 1996).

Memory span as a measure of individual differences in memory capacity

Two experiments were carried out to investigate whether the immediate digit span measure traditionally used in the assessment of individual differences in cognition is a good predictor of performance on other memory tasks. In the first experiment, it was found that subjects’ digit spans were not significantly related to their performances on either short-term or longterm memory tasks, or to theoretical measures of their memory store capacities. Memory for the temporal occurrence of events, however, proved to be positively correlated with digit span. A second experiment confirmed that digit span was correlated with memory for the temporal occurrence of events, but not with item memory. Thus it was concluded that an individual’s digit span reflects his ability to retain information about the order of a sequence of events rather than the capacity of his short- or long-term memory.     

Memory as discrimination: a challenge to the encoding-retrieval match principle

Four experiments contrasted the predictions of a general encoding-retrieval match hypothesis with those of a view claiming that the distinctiveness of the cue-target relationship is the causal factor in retrieval. In Experiments 1, 2, and 4 participants learned the relationships between 4 targets and trios of cues; in Experiment 3 there were 3 targets, each associated with a pair of cues. A learning phase was followed by a cued-recognition task where the correct target had to be identified based on 1 or more of the cues. The main performance measurement was response time. Learning was designed to lead to high accuracy so effects could be attributed to retrieval efficiency rather than to variations in encoding. The nature of the cues and targets was varied across experiments. The critical factor was whether each cue was uniquely associated with the to-be-recalled target. All experiments orthogonally manipulated (a) how discriminative-or uniquely associated with a target-each cue was and (b) the degree of overlap between the cues present during learning and those present at retrieval. The novel finding reported here is that increasing the encoding-retrieval match can hinder performance if the increase simultaneously reduces how well cues predict a target-that is, a cue's diagnostic value. Encoding-retrieval match was not the factor that determined the effectiveness of retrieval. Our findings suggest that increasing the encoding-retrieval match can lead to no change, an increase, or a decrease in retrieval performance.
