This paper briefly reviews the evidence for multistore theories of memory and points out some difficulties with the approach. An alternative framework for human memory research is then outlined in terms of depth or levels of processing. Some current data and arguments are reexamined in the light of this alternative framework and implications for further research considered.

To better understand the neurobiological mechanisms by which mindfulness-based practices function in a psychotherapeutic context, this article details the definition, techniques, and purposes ascribed to mindfulness training as described by its Buddhist tradition of origin and by contemporary neurocognitive models. Included is theory of how maladaptive mental processes become habitual and automatic, both from the Buddhist and Western psychological perspective. Specific noting and labeling techniques in open monitoring meditation, described in the Theravada and Western contemporary traditions, are highlighted as providing unique access to multiple modalities of awareness. Potential explicit and implicit mechanisms are discussed by which such techniques can contribute to transforming maladaptive habits of mind and perceptual and cognitive biases, improving efficiency, facilitating integration, and providing the flexibility to switch between systems of self-processing. Finally, a model is provided to describe the timing by which noting and labeling practices have the potential to influence different stages of low- and high-level neural processing. Hypotheses are proposed concerning both levels of processing in relation to the extent of practice. Implications for the nature of subjective experience and self-processing as it relates to one's habits of mind, behavior, and relation to the external world, are also described.

<p>This article describes the design and advocacy of the Bachelor of Fine Arts in Jazz and Contemplative Studies curriculum at The University of Michigan School of Music. The curriculum combines meditation practice and related studies with jazz and overall musical training and is part of a small but growing movement in academia that seeks to integrate contemplative disciplines within the educational process. The article considers issues such as the structure of the curriculum, the reconciliation of contemplative studies and conventional notions of academic rigor, the avoidance of possible conflicts between church and state, and other challenges encountered in gaining support for this plan, after weeks of intensive debate, from a 2/3 majority of the faculty.</p>

Three studies illustrate that mindful attention prevents impulses toward attractive food. Participants received a brief mindfulness procedure in which they observed their reactions to external stimuli as transient mental events rather than subjectively real experiences. Participants then applied this procedure to viewing pictures of highly attractive and neutral food items. Finally, reactions to food stimuli were assessed with an implicit approach-avoidance task. Across experiments, spontaneous approach reactions elicited by attractive food were fully eliminated in the mindful attention condition compared to the control condition, in which participants viewed the same items without mindful attention. These effects were maintained over a 5-minute distraction period. Our findings suggest that mindful attention to one’s own mental experiences helps to control impulsive responses and thus suggest mindfulness as a potentially powerful method for facilitating self-regulation.

Students with learning disabilities (LD; defined by compromised academic performance) often have higher levels of anxiety, school-related stress, and less optimal social skills compared with their typically developing peers. Previous health research indicates that meditation and relaxation training may be effective in reducing anxiety and promoting social skills. This pilot study used a pre—post no-control design to examine feasibility of, attitudes toward, and outcomes of a 5-week mindfulness meditation intervention administered to 34 adolescents diagnosed with LD. Postintervention survey responses overwhelmingly expressed positive attitudes toward the program. All outcome measures showed significant improvement, with participants who completed the program demonstrating decreased state and trait anxiety, enhanced social skills, and improved academic performance. Although not directly assessed, the outcomes are consistent with a cognitive-interference model of learning disability and suggest that mindfulness meditation decreases anxiety and detrimental self-focus of attention, which, in turn, promotes social skills and academic outcomes.

Different forms of learning and memory depend on functionally and anatomically separable neural circuits [Squire, L. R. (1992) Psychol. Rev. 99, 195–231]. Declarative memory relies on a medial temporal lobe system, whereas habit learning relies on the striatum [Cohen, N. J. & Eichenbaum, H. (1993) Memory, Amnesia, and the Hippocampal System (MIT Press, Cambridge, MA)]. How these systems are engaged to optimize learning and behavior is not clear. Here, we present results from functional neuroimaging showing that the presence of a demanding secondary task during learning modulates the degree to which subjects solve a problem using either declarative memory or habit learning. Dual-task conditions did not reduce accuracy but reduced the amount of declarative learning about the task. Medial temporal lobe activity was correlated with task performance and declarative knowledge after learning under single-task conditions, whereas performance was correlated with striatal activity after dual-task learning conditions. These results demonstrate a fundamental difference in these memory systems in their sensitivity to concurrent distraction. The results are consistent with the notion that declarative and habit learning compete to mediate task performance, and they suggest that the presence of distraction can bias this competition. These results have implications for learning in multitask situations, suggesting that, even if distraction does not decrease the overall level of learning, it can result in the acquisition of knowledge that can be applied less flexibly in new situations.

Mindful individuals orient to ongoing events and experiences in a receptive, attentive manner. This experiential mode of processing suggests implications for the perception of and response to stress situations. Using laboratory-based, longitudinal, and daily diary designs, four studies examined the role of mindfulness on appraisals of and coping with stress experiences in college students, and the consequences of such stress processing for well-being. Across the four studies (n’s = 65 − 141), results demonstrated that mindful individuals made more benign stress appraisals, reported less frequent use of avoidant coping strategies, and in two studies, reported higher use of approach coping. In turn, more adaptive stress responses and coping partially or fully mediated the relation between mindfulness and well-being. Implications for the role of mindfulness in stress and well-being are discussed.

This experiment was designed to explore whether brain norepinephrine (NE) serves as a specific reward system for the power drive. Previous research has indicated that 3-methoxy-4-hydroxyphenyl glycol (MHPG), a urinary metabolite reflecting central NE turnover, is positively correlated with features of assertiveness which one might expect of a person high in the need for power (n power) or in a state of aroused power motivation. Twenty-seven male undergraduates, 13 of whom were high and 14 of whom were low in n power as assessed by a TAT measure, were recruited as subjects. Before and after the laboratory session, subjects voided all urine and concentrations of epinephrine, norepinephrine and MHPG were obtained from samples. The laboratory task consisted of 20 picture-word pairs in which the subject had to learn to anticipate the word associated with each picture before the word was presented. Five pairs of stimuli in each of the following picture-word combinations were presented 12 times: neutral-neutral, neutral-power, power-neutral and power-power. The results revealed that, as predicted, subjects high in n power learn most power-related material faster than subjects low in n power. The need for achievement is unrelated to the learning of any picture-word pairs. The neurochemical data indicated that subjects maintaining a relatively high MHPG excretion rate during the experiment who were also high in n power showed the greatest mastery of power related compared with neutral picture-word pairs. These findings are consistent with the hypothesis that brain NE turnover is specifically related to the learning of power-related responses in subjects high in n power.

<p>Reviews selective behavioral, psychophysiological, and neuropsychological research bearing on how affective space should be parsed. Neither facial expression nor autonomic nervous system activity is found to provide unique markers for particular discrete emotions. The dimensions of approach and withdrawal are introduced as fundamental systems relevant to differentiating affective space. The role of frontal and anterior temporal asymmetries in mediating approach- and withdrawal-related emotion is considered. Individual differences in tonic anterior activation asymmetry are present and are relatively stable over time. Such differences are associated with an individual's propensity to display different types of emotion, mood, and psychopathology. The conceptual and methodological implications of this perspective are considered.</p>

<p>Literature is reviewed suggesting that a child's personality determines to a large extent his or her reaction to specific methods of teaching, and even to the whole ethos and atmosphere of the teaching situation. Thus, extraverted children benefit from being taught along the lines of discovery learning, while introverted children benefit from being taught along the lines of reception learning. The apparent lack of difference in achievement in groups taught by these methods hides the large individual differences factor that appears in the interaction term. It is suggested that facts of this kind should be of considerable concern to those who design our courses for future teachers, and for teachers generally. We owe our children care in the design of methods for teaching, and personality differences play an important part in such design.</p>

A cardinal dimension of adult development and the learning most uniquely adult pertains to becoming aware that one is caught in one's own history and is reliving it. This leads to a process of perspective transforma tion involving a structural change in the way we see ourselves and our rela tionships. If the culture permits, we move toward perspectives which are more inclusive, discriminating and integrative of experience. We move away from uncritical, organic relationships toward contractual relation ships with others, institutions and society. Perspective transformation refor mulates the criteria for valuing and for taking action. Behavior change is often a function of such transformation. In this emerging transformation theory, adult education finds its own inherent goals and functions.

The aim of this article is to investigate how a contemplative orientation to teaching may facilitate wholeness for teachers and students through a portrait of Diana, a kindergarten teacher working in a contemplative elementary school. The portrait, one of three portraits from a larger study, illustrates three central features of contemplative teaching: compassion, integrity, and mindful awareness. These three central features develop internally within individual teachers and are animated and influenced externally through their role as teachers. The context of their teaching, relationships with students, parents, and colleagues, and pedagogical choices, in turn influence the three central features. The emphasis on wholeness, unity, and integration of a contemplative orientation to teaching moves us toward a view of teachers and students as beings with not only minds and heads but also hearts and bodies. Contemplative teaching offers educational communities a path toward transformational, holistic, and integrative learning and teaching.

Work in philosophy and psychology has argued for a dissociation between perceptually-based similarity and higher-level rules in conceptual thought. Although such a dissociation may be justified at times, our goal is to illustrate ways in which conceptual processing is grounded in perception, both for perceptual similarity and abstract rules. We discuss the advantages, power and influences of perceptually-based representations. First, many of the properties associated with amodal symbol systems can be achieved with perceptually-based systems as well (e.g. productivity). Second, relatively raw perceptual representations are powerful because they can implicitly represent properties in an analog fashion. Third, perception naturally provides impressions of overall similarity, exactly the type of similarity useful for establishing many common categories. Fourth, perceptual similarity is not static but becomes tuned over time to conceptual demands. Fifth, the original motivation or basis for sophisticated cognition is often less sophisticated perceptual similarity. Sixth, perceptual simulation occurs even in conceptual tasks that have no explicit perceptual demands. Parallels between perceptual and conceptual processes suggest that many mechanisms typically associated with abstract thought are also present in perception, and that perceptual processes provide useful mechanisms that may be co-opted by abstract thought.

<p>Subregional analyses of the hippocampus have suggested a selective role for the CA1 subregion in intermediate/long-term spatial memory and consolidation, but not short-term acquisition or encoding processes. It remains unclear how the direct cortical projection to CA1 via the perforant path (pp) contributes to these CA1-dependent processes. It has been suggested that dopamine selectively modulates the pp projection to CA1 while having little to no effect on the Schaffer collateral (SC) projection to CA1. This series of behavioral and electrophysiological experiments takes advantage of this pharmacological dissociation to demonstrate that the direct pp inputs to CA1 are critical in CA1-dependent intermediate-term retention and retrieval function. Here we demonstrate that local infusion of the nonselective dopamine agonist, apomorphine (10, 15 microg), into the CA1 subregion of awake animals produces impairments in between-day retention and retrieval, sparing within-day encoding of a modified Hebb-Williams maze and contextual conditioning of fear. In contrast, apomorphine produces no deficits when infused into the CA3 subregion. To complement the behavioral analyses, electrophysiological data was collected. In anesthetized animals, local infusion of the same doses of apomorphine significantly modifies evoked responses in the distal dendrites of CA1 following angular bundle stimulation, but produces no significant effects in the more proximal dendritic layer following stimulation of the SC. These results support a modulatory role for dopamine in the EC-CA1, but not CA3-CA1 circuitry, and suggest the possibility of a more fundamental role for EC-CA1 synaptic transmission in terms of intermediate-term, but not short-term spatial memory.</p>

The current study investigated the effects of an 8-week mindfulness-based meditation training (MMT) intervention on attentional bias, engagement and disengagement of pain-related threat in fibromyalgia patients as compared to an age-matched control group. A well validated dot-probe task was used to explore early versus later stages of attentional processing through the use of two stimulus exposure durations (100, 500 ms) of pain-related threat words. The enduring effects of MMT were assessed 6-months after completion of MMT. Preliminary results suggest that MMT reduces avoidance of pain-related threat at early levels of processing, and facilitates disengagement from threat at later stages of processing. Furthermore, it appears that effects of MMT on early attentional threat processing do not remain stable after long-term follow-up.

Three experiments demonstrated that situational information contributes to the categorization of functional object categories, as well as to inferences about these categories. When an object was presented in the context of setting and event information, categorization was more accurate than when the object was presented in isolation. Inferences about the object similarly became more accurate as the amount of situational information present during categorization increased. The benefits of situational information were higher when both setting and event information were available than when only setting information was available. These findings indicate that situational information about settings and events is stored with functional object categories in memory. Categorization and inference become increasingly accurate as the information available during categorization matches situational information stored with the category.
