We examine and reject the claim that the past-directed aspect of mental time travel (episodic memory) is unique to humans. Recent work in our laboratory with rats has demonstrated behaviours that resemble judgements about past occasions. Similar to human episodic memory, we can also demonstrate a dissociation in the neural basis of recollection and familiarity in nonhumans.

This article addresses, experimentally, the question of how presuppositions are cognitively processed and retrieved in discourse. In the proposed research, we have administered tweets produced by Italian politicians to native speakers so as to assess how easily they could retrieve the presupposed content of two presupposition triggers (definite descriptions and change of state verbs), as opposed to their explicit paraphrase, by answering verification questions. Results showed that content presupposed by change of state verbs was likely to receive more attention than (...) content conveyed by definite descriptions; this could possibly be due to the greater effort involved in mentally representing the event taken for granted by the predicates. Definite descriptions, on the contrary, seem to instruct to a shallower processing modality, which means that their content is processed less attentively or in a ‘good-enough’ way. (shrink)

The emotions that people experience in day-to-day social situations are often mixed emotions. Although autobiographical recall is useful as an emotion induction procedure, it often involves recalling memories associated with a specific discrete emotion. However, real-life emotions occur freely and spontaneously, without such constraints. To understand real-life emotions, the present study examined characteristics of emotions that were elicited by recalling “stressful interpersonal events in daily life” without the targeted evocation of a specific discrete emotion. Assuming generation of mixed and (...) complex emotions, emotional groups with relatively strong correlation of multiple emotions according to surprise, fear, anger, disgust, sadness, and happiness were expected. Seventy-two university students participated in the study. In the emotion induction procedure, participants freely recalled memories as per the instructions on a monitor, and then responded silently to a series of questions concerning any one recalled incident. Assessments of emotional states using emotion scales and another item indicated that validated emotional changes had occurred during the task. Inter-correlations between six emotions demonstrated an emotional group consisting of disgust and anger, which frequently occur as negative interpersonal feelings, and that of fear and sadness. This indicated generation of mixed and complex emotions as experienced in social life. Future studies concerning relationships between these emotions and other factors, including neurophysiological responses, may facilitate further understanding about relationships between mental and physiological processes occurring in daily life.

Do we mentally simulate olfactory information? We investigated mental simulation of odors and sounds in two experiments. Participants retained a word while they smelled an odor or heard a sound, then rated odor/sound intensity and recalled the word. Later odor/sound recognition was also tested, and pleasantness and familiarity judgments were collected. Word recall was slower when the sound and sound-word mismatched. Sound recognition was higher when sounds were paired with a match or near-match word. This indicates sound-words are (...) mentally simulated. However, using the same paradigm no memory effects were observed for odor. Instead it appears odor-words only affect lexical-semantic representations, demonstrated by higher ratings of odor intensity and pleasantness when an odor was paired with a match or near-match word. These results suggest fundamental differences in how odor and sound-words are represented. (shrink)

There are different ways of defining science, but I should like to examine it primarily as one of the forms of mental labor. In this connection it is appropriate to recall Marx's words: "A distinction must be made between universal labor and cooperative labor. Each plays its own role in the process of production. They overlap, but there is also a distinction between them. Every scientific work, every discovery, every invention is universal labor. It is made possible partly (...) by cooperation among contemporaries and partly by making use of the work of those who have gone before. Joint labor presumes direct cooperation among individuals." What is subsumed here under "cooperative labor," according to Marx, is "directly associated labor," which, to put it in other terms, is "direct labor.". (shrink)

Mental imagery is an important topic in classical and modern philosophy, as it is central to the study of knowledge; since subjects can recall features of perceptual experiences in different ways and times, even modifying their structure, in this brief essay we will focus on non-perceptive mental images and to this purpose we will analyse, on the one hand, the nature of perceptive mental images ; on the other hand, NPMI generation according to different strategic conditions (...) and retrieval modalities and, so, their structural relationships with PMI. Thus, we will clarify what NPMI amounts to and, to this purpose, we will address the issue of epistemic correlation and semantic reference. As regards the former, we will adopt the notion of ‘belief’, both to describe which attitude supports the use of an NPMI and to account for its relationship with a PMI. As regards the latter, we will talk about weak ontology between an NPMI and the world, to conceive ‘the way in which’ mental imagery, despite the absence of a sensorial modification, refers to physical objects. As the subject’s mental contents determine, but do not constrain, what NPMI is like, we will deal with the ‘involvement’ of prior knowledge and the notion of meaningful space to underline that its generation is always the result of a wide process which involves perceptive visual information already processed and stored together with further mental contents. So, though some Authors consider mental imagery to be a ‘percept-like’ image and, somehow, espouse the theory of reactivation, we will pose a challenge to this theory – i.e. to what we call mental imagery standard framework – describing an NPMI in terms of configurational setting and indeterminacy. Consequently, we will propose a non-linear dynamic framework of mental imagery generation , according to which an NPMI is not reducible to a mere recalling of figural features of a perceptive image.

Miller (1956) summarized evidence that people can remember about seven chunks in short-term memory (STM) tasks. However, that number was meant more as a rough estimate and a rhetorical device than as a real capacity limit. Others have since suggested that there is a more precise capacity limit, but that it is only three to five chunks. The present target article brings together a wide variety of data on capacity limits suggesting that the smaller capacity limit is real. Capacity limits (...) will be useful in analyses of information processing only if the boundary conditions for observing them can be carefully described. Four basic conditions in which chunks can be identified and capacity limits can accordingly be observed are: (1) when information overload limits chunks to individual stimulus items, (2) when other steps are taken specifically to block the recoding of stimulus items into larger chunks, (3) in performance discontinuities caused by the capacity limit, and (4) in various indirect effects of the capacity limit. Under these conditions, rehearsal and long-term memory cannot be used to combine stimulus items into chunks of an unknown size; nor can storage mechanisms that are not capacity-limited, such as sensory memory, allow the capacity-limited storage mechanism to be refilled during recall. A single, central capacity limit averaging about four chunks is implicated along with other, noncapacity-limited sources. The pure STM capacity limit expressed in chunks is distinguished from compound STM limits obtained when the number of separately held chunks is unclear. Reasons why pure capacity estimates fall within a narrow range are discussed and a capacity limit for the focus of attention is proposed. Key Words: attention; enumeration; information chunks; memory capacity; processing capacity; processing channels; serial recall; short-term memory; storage capacity; verbal recall; working memory capacity.

Wittgenstein likens philosophy both to an illness and to a therapy. The reflections he dedicates to mental disturbance in On Certainty shed some light on this ambivalence, by pointing at the intertwined themes of common sense, doubt, mistake, reasonableness, and normality. Wittgenstein’s remarks have sometimes been compared to the description of the symptoms of what psychopathologists have called the loss of natural self-evidence, or the loss of common sense. Besides briefly recalling some of the outcomes of this debate in (...) literature, I focus on Wittgenstein’s conception of “hinges”, the basic practical certainties which patients suffering from the loss of common sense seem to lack. By working on this comparison, I offer an interpretation of Wittgenstein’s idea of philosophy that clarifies both its insane and its therapeutic side. (shrink)

After thirty years of the current “imagery debate,” it appears far from resolved, even though there seems to be a growing acceptance that a cortical display cannot be identified directly with the experienced mental image, nor can it account for the experimental findings on imagery, at least not without additional ad hoc assumptions. The commentaries on the target article range from the annoyed to the supportive, with a surprising number of the latter. In this response I attempt to correct (...) some misreadings of the target article and discuss some of the ideas and evidence introduced by the commentators – much of which I found helpful, even though they do not alter my basic thesis. I also further develop the idea that the spatial character of images may come from the way they are connected to our immediate or immediately-recalled environment (by attention or by visual indexes) and towards which we may orient while we are imaging, thus leaving the alleged spatial properties of images outside the head and freeing image-representations from having to be displayed on any surface.

Ukrainian national pedagogy has always been based on the organic combination of national and Christian ideals. Christian humanity was the norm of interpersonal, interethnic, and everyday social existence of our people. The modern Ukrainian society needs spiritual improvement, which is obviously, according to the author, only in the interaction of four fundamental factors: the state, the Church, the system of education and the family. The features of Ukrainian spirituality and mental characteristics were the object of research by M.Kostomarov, V.Antonovich. (...) P. Kulis, T. Shevchenko, M. Hrushevsky. I.Franko, V.Lipinsky, O.Kulchytsky, G.Vaschenko, A.Richinsky and V.Yaniva. Today it is right to recall the words of the outstanding Ukrainian teacher G.Vaschenko, who insisted, first of all, on the implementation of the principle of educational education, which should follow the slogan "service to God and the Motherland", and therefore it is necessary to ensure the unity of national and Christian ideals in the present titular nation [Vashchenko P General principles teaching. In 4 parts - Munich: B.V., 1948. - 4.1. - 285 s.]. The bitter prophecy is the saying of the Ukrainian enlightener A.Richinsky: "The result of spiritual fatigue is that the life of the people becomes too materialistic. With the decline of national shrines and unifying ideology, everyone cares only about the private interest, the provision of material well-being, feeling already impotent to dream of the higher ideals of the nation "[Rychinsky A.

We investigate the common development of children’s ability to “look back in time” and to “look into the future” . Experiment 1 with 59 children 5 to 8.5 years old showed mental rotation, as a measure of prospection, explaining specific variance of free recall, as a measure of episodic remembering when controlled for cued recall. Experiment 2 with 31 children from 5 to 6.5 years measured episodic remembering with recall of visually experienced events when controlling for (...) recall of indirectly conveyed events . Quite unexpectedly rotators were markedly worse on indirect items than non-rotators. We speculate that with the ability to rotate children switch from knowledge retrieval to episodic remembering, which maintains success for experienced events but has detrimental effects for indirect information.

Despite its association with individual health, few studies have focused on the relationship between adolescent self-control and individual physical and mental health in adulthood. We aimed, therefore, to explore the impact of adolescent self-control on individual physical and mental health in adulthood. We employed the dataset of China Labor-Force Dynamics Surveys [CLDS]. 13,389 respondents with an average age of 45.621 years are consisted in this study. The respondents were asked to report their adolescent self-control through recall. The (...) ordered probit and the ordinary least squares models were employed to estimate the effects of adolescent self-control on physical and mental health in adulthood, respectively. We adopted the propensity score matching method to address the self-selection bias of samples. The results indicated that adolescent self-control significantly affected individual physical health and mental health in adulthood. The mechanism analysis suggested that adolescent self-control partially promoted physical and mental health in adulthood by education and income instead of self-control in adulthood. In conclusion, paying attention to the cultivation of self-control before adulthood may be an effective way to improve individual physical and mental health in adulthood. (shrink)

Mackenzie Graham has made an important contribution to the literature on decisionmaking for patients with disorders of consciousness. He argues, and I agree, that decisions for unresponsive patients who are known to retain some degree of covert awareness ought to focus on current interests, since such patients likely retain the kinds of mental capacities that in ordinary life command our current respect and attention. If he is right, then it is not appropriate to make decisions for such patients by (...) appealing to the values they had in the past, either the values expressed in an advance directive or the values recalled by a surrogate. There are two things I wish to add to the discussion. My first point is somewhat critical, for although I agree with his general conclusion about how, ideally, such decisions should be approached, I remain skeptical about whether his conclusion offers decisionmakers real practical help. The problem with these cases is that the evidence we have about the nature of the patient’s current interests is minimal or nonexistent. However—and this is important—Graham’s conclusion will be extremely relevant if in the future, our ability to communicate with such patients improves, as I hope it will. This leads to my second point. Graham’s conclusion illustrates a more general problem with our standard framework for decisionmaking for previously competent patients, a problem that has not been adequately recognized. So, in what follows, I explain the problem I see and offer some brief thoughts about solutions. (shrink)

Current models of autobiographical memory suggest that self-identity guides autobiographical memory retrieval. Further, the capacity to recall the past and imagine one’s self in the future can influence social problem solving. We examined whether manipulating self-identity, through an induction task in which students were led to believe they possessed high or low self-efficacy, impacted episodic specificity and content of retrieved and imagined events, as well as social problem solving. Compared to individuals in the low self efficacy group, individuals in (...) the high self efficacy group generated past and future events with greater specificity, positive words, and self-efficacious statements, and also performed better on social problem solving indices. A lack of episodic detail for future events predicted poorer performance on social problem solving tasks. Strategies that increase perceived self-efficacy may help individuals to selectively construct a past and future that aids in negotiating social problems. (shrink)

Nostalgia as one of the complex emotions has been challenged over the past few decades due to its psychological and physiological functions. The present experiment investigates the effect of recalling nostalgic memories on amelioration of homeostatic and health state of people with cardiovascular disease. Method: The participants were 30 patients who were hospitalized for angiography procedure. The research was based on an experimental design with randomized and post-test groups. The instruments used included a thermometer with ° C, a checkout manipulation (...) test, a blood pressure monitor, an ice container and a manual timer, a pain intensity perception scale and Batcho’s nostalgia questionnaire. Results: The results showed that there was a significant difference between the two groups in perceived temperature, the resilience in the face of pain, and the perceived pain. The experimental group perceived higher temperature and showed greater resilience in the face of pain and also lower pain intensity was reported. There was no significant difference in blood pressure between the two groups. Conclusion: The results of this study provide significant evidence for the embodiment emotions hypothesis and positive role of Nostalgia in psychological and physiological homeostatic. Further practical implications of results and suggestions for future research were considered. (shrink)

In order to predict and explain behavior, one cannot specify the mental state of an agent merely by saying what information she possesses. Instead one must specify what information is available to an agent relative to various purposes. Specifying mental states in this way allows us to accommodate cases of imperfect recall, cognitive accomplishments involved in logical deduction, the mental states of confused or fragmented subjects, and the difference between propositional knowledge and know-how .

Conscious recollection, of the kind characterised by sensory mental imagery, is often thought to involve ‘episodically’ recalling experienced events in one’s personal past. One might wonder whether this overlooks distinctive ways in which we sometimes recall ordinary, persisting objects. Of course, one can recall an object by remembering an event in which one encountered it. But are there acts of recall which are distinctively objectual in that they are not about objects in this mediated way (i.e., (...) by way of being about events in which they featured)? This question has broad implications, not least for understanding the nature and role of imagery in remembering, the requirements of memory-based singular thought about objects, and the sense in which remembering involves ‘mental time travel’ through which one ‘relives’ past events. In this paper, I argue that we sometimes do recall objects from our past without remembering events in which they featured. The positive view of such cases I go on to propose draws on a wide body of empirical work in its support and accommodates a more nuanced picture of the role of imagery in remembering. In a slogan: remembering might essentially involve a kind of ‘re-experiencing’, but it need not involve ‘reliving’. (shrink)

Surprise has been explored as a cognitive-emotional phenomenon that impacts many aspects of mental life from creativity to learning to decision-making. In this paper, we specifically address the role of surprise in learning and memory. Although surprise has been cast as a basic emotion since Darwin's (1872) The Expression of the Emotions in Man and Animals, recently more emphasis has been placed on its cognitive aspects. One such view casts surprise as a process of “sense making” or “explanation finding”: (...) metacognitive explanation-based theory proposes that people's perception of surprise is a metacognitive assessment of the cognitive work done to explain a surprising outcome. Or, to put it more simply, surprise increases with the explanatory work required to resolve it. This theory predicts that some surprises should be more surprising than others because they are harder to explain. In the current paper, this theory is extended to consider the role of surprise in learning as evidenced by memorability. This theory is tested to determine how scenarios with differentially surprising outcomes impact the memorability of those outcomes. The results show that surprising outcomes (less-known outcomes) that are more difficult to explain are recalled more accurately than less-surprising outcomes that require little (known outcomes) or no explanation (normal).

Is consolidation needed to account for retroactive interference in free recall? Interfering mental activity during the retention interval of a memory task impairs performance, in particular if the interference occurs in temporal proximity to the encoding of the to-be-remembered information. There are at least two rival theoretical accounts of this temporal gradient of retroactive interference. The cognitive neuroscience literature has suggested neural consolidation is a pivotal factor determining item recall. According to this account, interfering activity interrupts consolidation (...) processes that would otherwise stabilize the memory representations of TBR items post-encoding. Temporal distinctiveness theory, by contrast, proposes that the retrievability of items depends on their isolation in psychological time. According to this theory, information processed after the encoding of TBR material will reduce the temporal distinctiveness of the TBR information. To test between these accounts, implementations of consolidation were added to the SIMPLE model of memory and learning. We report data from two experiments utilizing a two-list free recall paradigm. Modeling results imply that SIMPLE was able to model the data and did not benefit from the addition of consolidation. It is concluded that the temporal gradient of retroactive interference cannot be taken as evidence for memory consolidation. (shrink)

The paper presents, first, some general remarks about Husserl’s philosophical Phenomenology in view of relating it to the scientific study of consciousness, and recalls some of the basic methodological tenets of a Husserlian phenomenology of consciousness (I). It then introduces some recent work on so-called “mental imagery” in cognitive psychology and neuroscience (II). Next, a detailed exposition of a reflective analysis of conscious experiences that involve “imagery” or “images” is given (III), arguing thereby that reflective conceptual clarifications of various (...) forms of such experiences could contribute to research into their finer details. In order to show more distinctly that the conscious experiences involved in the contemporary cognitive and neuroscientific imagery research are indeed differently structured, a simple notation for designating the various structural components of the experiences under study will be used. In concluding (IV), some methodological assets concerning the present proposal of integrating the method of Husserlian phenomenology into the present-day, and hopefully even more so into the future study of consciousness are highlighted!

The deep comprehension of a text is tantamount to the construction of an articulated mental model of that text. The number of correct recollections is an index of a learner's mental model of a text. We assume that another index of comprehension is the timing of the gestures produced during text recall; gestures are simultaneous with speech when the learner has built an articulated mental model of the text, whereas they anticipate the speech when the learner (...) has built a less articulated mental model. The results of four experiments confirm the predictions deriving from our assumptions for both children and adults. Provided that the recollections are correct, the timing of gestures can differ and can be considered a further measure of the quality of the mental model, beyond the number of correct recollections.

In recent decades, memory has become one of the major concepts and a dominant topic in philosophy, sociology, politics, history, science, cultural studies, literary theory, and the discussions of trauma and the Holocaust. In contemporary debates, the concept of memory is often used rather broadly and thus not always unambiguously. For this reason, the clarification of the range of the historical meaning of the concept of memory is a very important and urgent task. This volume shows how the concept of (...) memory has been used and appropriated in different historical circumstances and how it has changed throughout the history of philosophy. In ancient philosophy, memory was considered a repository of sensible and mental impressions and was complemented by recollection-the process of recovering the content of past thoughts and perceptions. Such an understanding of memory led to the development both of mnemotechnics and the attempts to locate memory within the structure of cognitive faculties. In contemporary philosophical and historical debates, memory frequently substitutes for reason by becoming a predominant capacity to which one refers when one wants to explain not only the personal identity but also a historical, political, or social phenomenon. In contemporary interpretation, it is memory, and not reason, that acts in and through human actions and history, which is a critical reaction to the overly rationalized and simplified concept of reason in the Enlightenment. Moreover, in modernity memory has taken on one of the most distinctive features of reason: it is thought of as capable not only of recollecting past events and meanings, but also itself. In this respect, the volume can be also taken as a reflective philosophical attempt by memory to recall itself, its functioning and transformations throughout its own history. (shrink)

Eye movements during mental imagery are not epiphenomenal but assist the process of image generation. Commands to the eyes for each fixation are stored along with the visual representation and are used as spatial index in a motor‐based coordinate system for the proper arrangement of parts of an image. In two experiments, subjects viewed an irregular checkerboard or color pictures of fish and were subsequently asked to form mental images of these stimuli while keeping their eyes open. During (...) the perceptual phase, a group of subjects was requested to maintain fixation onto the screen's center, whereas another group was free to inspect the stimuli. During the imagery phase, all of these subjects were free to move their eyes. A third group of subjects (in Experiment 2) was free to explore the pattern but was requested to maintain central fixation during imagery. For subjects free to explore the pattern, the percentage of time spent fixating a specific location during perception was highly correlated with the time spent on the same (empty) locations during imagery. The order of scanning of these locations during imagery was correlated to the original order during perception. The strength of relatedness of these scanpaths and the vividness of each image predicted performance accuracy. Subjects who fixed their gaze centrally during perception did the same spontaneously during imagery. Subjects free to explore during perception, but maintaining central fixation during imagery, showed decreased ability to recall the pattern. We conclude that the eye scanpaths during visual imagery reenact those of perception of the same visual scene and that they play a functional role. (shrink)

In Thinking About Consciousness , David Papineau [2002] presents a criticism of so-called 'actualist HOT theories of consciousness'. The HOT theory, held most notably by David Rosenthal, claims that the best explanation for what makes a mental state conscious is that it is the object of an actual higher-order thought directed at the mental state. Papineau contends that actualist HOT theory faces an awkward problem in relation to higher-order memory judgements; for example, that the theory cannot explain how (...) one could later recall an earlier experience that was not introspected. He argues that, on the HOT theory, we are even left with the absurd conclusion that the consciousness of, say, an earlier visual experience might even depend on the later act of memory. I show that Papineau's criticism of actualist HOT theory not only fails, but also that it seriously mischaracterizes and underestimates the theory. In particular, Papineau badly conflates the crucial difference between an introspective state and an outer-directed first-order conscious state. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Phenomenological Interviews and Tourette'sThe authors report no conflicts of interest.We appreciate the responses from the two clinicians, Efron and Mathieson. We agree with their reminder about the holistic nature of clinician's engagement (mood, sociality, and work life) and with their emphasis on patient-reported outcome measures, although this is not quite what we did in our interviews. As has recently been recognized in section 24 of the Victorian Mental (...) Health and Well-being Act (to provide a local Australian example), patients and caregivers' "lived experience makes them valuable leaders and active partners in the mental health and wellbeing service system."1In this paper, however, our aim was both more modest and immodest: modest, in that we aimed to work with those "leaders and active partners" to generate a more adequate account of lived experience in concert with behavioral symptomatology; immodest, in that we wondered how the lived experience of Tourette syndrome (TS) aligned (or not) with some of the commonly ascribed features of the condition. Although phenomenology as a discipline does not own lived experience, of course, it is more systematically treated in this tradition, starting with elaborations of Erlebnis.Efron and Mathieson note that older patients are more likely to describe urges or premonitory urges (PUs). This raises the priming question: Has greater exposure to and involvement in medical concepts and treatments transformed the nature of their self-report, or has it provided them with more phenomenological skills, enabling them to pick out discrete parts of experience? Or perhaps they have just been exposed more frequently to the experience over time? We address some related issues below, in our reply to Fernandez, where we outline our interview techniques more fully.They end by noting that the aim of comprehensive behavioral intervention for tics is to become attentive to PUs to better block tics. This is complex and understudied. In principle, becoming aware of something cognitively and experientially can foreground or even perhaps induce that experience. Conversely, from the TS scholarship, we know that attending to urges in certain ways (e.g., via acceptance training) can also reduce perceived urge frequency and intensity (see Gev et al., 2016). We would welcome further work on this link between attention and experience in TS. [End Page 49]Response to FernandezBecause our paper was partly framed around Fernandez' own work on phenomenological psychopathology, we welcome his invitation to provide further "inspiration and guidance" for other phenomenological researchers conducting empirical studies, who may also be dealing with the challenge posed by "narrative habits." When an interviewee uses well-worn medicalized terms to describe their experience, it is not clear whether these descriptions genuinely reveal or rather occlude the experience in question. There are sometimes, perhaps often, second-person phenomenological 'tells' regarding interviewees genuinely re-evoking an experience, but for interviewers it still raises the question of how to prompt alternative and potentially more accurate descriptions of experience.Because of this challenge, we purposely did not use the term "urge" or "premonitory urge" (PU) in our interview questions. Instead, we asked about (and used the broader term of) "experiences" that may occur prior, during, or after ticcing, without assuming that there are such experiences in the first place. We guided interviewees to evoke the memory of a specific, singular tic event (a tic token; see Curtis-Wendlandt 2020, 2023). Once a memory of such an event had been identified, we asked interviewees the following three lead questions:1. What, if anything, did you experience during this tic?2. What, if anything, did you experience before this tic?3. What, if anything did you experience after this tic?The temporal framing of these questions counters common trends and assumptions in the scholarship, which has focused heavily on pre-tic experiences, with little attention given to post-tic experiences (reduced to notions of "relief" and barely investigated), and even less to experiential explorations of the tic itself. Our catalogue of supporting questions sought to elicit fine-grained descriptions of evoked/recalled experiences along sensory and cognitive-affective dimensions:•. Did you see anything before, during, or after this tic? If so, what did you see?•. Did you hear anything... (shrink)

To test whether mental activities collected from non-REM sleep are influenced by REM sleep, we suppressed REM sleep using clomipramine 50 mg or placebo in the evening, in a double blind cross-over design, in 11 healthy young men. Subjects were awakened every hour and asked about their mental activity. The marked REM-sleep suppression induced by clomipramine did not substantially affect any aspects of dream recall . Since long, complex and bizarre dreams persist even after suppressing REM sleep (...) either partially or totally, it suggests that the generation of mental activity during sleep is independent of sleep stage.

Many people who were Saturday Night Live fans in the 1990s recall the firing of Norm Macdonald as a watershed moment. In exploring theories about why people employ humor, they just might be able to discover the motivations behind Macdonald's firing. Macdonald offered a different assessment of his firing in an oral history of Saturday Night Live, saying that it came down to a philosophical disagreement between NBC management and himself about the goal of “Weekend Update.” Macdonald's requirement that (...) laughter be involuntary tracks well with Max Eastman's philosophical theory of humor known as play theory. Sigmund Freud's Relief Theory suggests that the main goal of humor and laughter is to relieve pent up stresses and mental strain that people carry around with them. The most important difference between humor‐as‐relief and play theory is that in play theory the release is a positive consequence, but not the intended goal. (shrink)

Schizophrenia is a severe mental illness affecting sense of identity. Autobiographical memory deficits observed in schizophrenia could contribute to this altered sense of identity. The ability to give a meaning to personally significant events is also critical for identity construction and self-coherence. Twenty-four patients with schizophrenia and 24 control participants were asked to recall five self-defining memories. We assessed meaning making in participants’ narratives and afterwards asked them explicitly to give a meaning to their memories . We found (...) that both spontaneous and cued meaning making were impaired in patients with schizophrenia. This impairment was correlated with executive dysfunctions and level of negative symptoms. Our results suggest that patients’ difficulties in drawing lessons about past experiences could contribute to explain the lack of coherence observed in their life trajectories and their impaired social adjustment abilities. Implications for psychotherapy are also discussed. (shrink)

The human brain is the first computer to which all others are compared. Yet we know painfully little about how a brain accomplishes its peculiar computations. In particular, consciousness is at once familiar and mysterious, and needs to be understood both for science and for medicine. Boldly, but gently this book introduces a reader to the neural circuitry that achieves consciousness. This amazing interconnection enables consciousness to flow like a stream, intimately relevant to the outside world; and for this to (...) happen, fundamental cues emerge from mental images to bring forth associated recalls. Alas cues can be inconsistent, causing memory failure; fortunately a subliminal cue editor encourages remembering forgotten items. Furthermore, cues generally address several memories, forcing the brain to make a selection. This necessitates another special circuit whose purpose is subliminal editing. The simplified explanations provided in this book make it clear that neurons do far more than ordinary devices, since a single neuron is capable of remarkably dense combinational and sequential logic. Beginning with their interesting and unexpected logical behavior, the reader will genuinely enjoy Dr. Burger's synthesis of a system for biological consciousness, a system that may someday result in credible artificial consciousness.
