Age disorientation in chronic schizophrenia is associated with global intellectual impairment.

From a population of long-stay patients with a diagnosis of schizophrenia according to the St Louis criteria, a group of 21 patients with 'age disorientation' was selected, and compared on a series of tests of intellect and learning capacity with a matched control group of 21 schizophrenic patients without this feature. The age-disorientated patients demonstrated substantial impairments on tests of orientation and general knowledge, associational learning, the 'famous personality' test, tests of vocabulary and aphasia, Raven's matrices, the digit-symbol substitution test and the mental test score. We conclude that profound 'organic-type' psychological deficits (global impairment of intellectual function associated with temporal disorientation) undoubtedly occur in chronic schizophrenia. The findings on the 'famous personality' test and the Peabody vocabulary test did not exclude the possibility that such impairment arises early in life, at a time preceding the onset of the illness which leads to hospital admission.

Anomia for people names in DAT--evidence for semantic and post-semantic impairments.

Proper name anomia is a frequent finding among patients in the early stages of Alzheimer's disease. The present study investigates naming of famous persons in a group of DAT patients, a group of persons with mild cognitive impairment (MCI) and healthy controls. The study is aimed at distinguishing the relative contributions of semantic and post-semantic factors to difficulties in proper name retrieval. As shown by a significantly lower score in answering semantic questions, DAT patients retrieve less biographical knowledge related to famous persons than healthy elderly subjects and persons with mild cognitive impairment. This finding is in line with the frequent observation of semantic deficits in early and moderate DAT. The high number of Tip-of-the-Tongue (TOT) answers in DAT found in relation to few spontaneously named items shows that post-semantic deficits are as important as semantic deficits in determining anomia for people names in DAT. Moreover, DAT patients were less sensitive to phonological cueing than healthy persons or persons with mild cognitive impairment. These findings suggest that proper name anomia in DAT is not only due to semantic deficits, but also to problems in accessing the phonological representation, as well as to a degradation of phonological representations. Thus, naming deficits in DAT differ not only quantitatively, but also qualitatively from the difficulties of healthy elderly persons. No significant differences were found between persons with mild cognitive impairment and healthy controls in proper name retrieval.

[The dishonest, the ignorant and the insane artists--psychopathography and other paths to soul of the artist].

Psychopathography is a specific kind of biography focusing on psychological and psychopathological aspects of the personality and their significance for creative activity, especially in famous persons. Psychopathography evolved as a discipline from the 1830's onwards, as a product of psychiatry emerging as a science, reflecting its reductionist and nosological approach. An illustration of this method is the analysis of the author E.T.A. Hoffmann, a prototypical representative of the German romanticism at the beginning of the century. Hoffmann himself expresses, in allegorical terms, the menacing, irrational and unconscious domains of the human soul. Romanticism may be seen as a forerunner of the psychoanalytic movement. Confronted with modernism in art, pathographic considerations were to a large extent based upon the object of art itself, often with arrogant and repudiating conclusions concerning the artist. Classical psychoanalysis has had a marked tendency to deduce a great deal about the personality of the artist or the writer solely from analysis of a picture or written text. The pathographic approach of the first century of scientific psychiatry has had a renaissance over the last 15-20 years: The ever increasing interest in affective syndromes has entailed a tendency to trace and identify affective pathology in artists and writers, deceased or alive, often emphasizing the affective dynamics of the creative process, aspects also noted by the classical pathographers. More recent studies of the creative personality may also present improved instruments for the study of the creative process.

The categorical structure of knowledge for famous people (and a novel application of Centre-Surround theory).

Knowledge of familiar people is essential to guide social interaction, yet there is uncertainty about whether semantic knowledge for people is stored in a categorical structure as for objects. Four priming experiments using hard-to-perceive primes investigated whether occupation forms a category connecting famous persons in semantic memory. Primes were famous faces exposed for 17ms with masking, resulting in severely restricted awareness and thus precluding expectancy-based priming effects. Targets were consciously perceptible famous faces (Experiments 1-3), famous names (Experiment 3), or occupations (Experiment 4) representing either the same or different occupation to the prime. Significant priming demonstrated the operation of automatic processes, including spreading activation, among persons sharing a common occupation; this supports the categorical view. The direction of priming (faster/slower responses to same-occupation than different-occupation targets) was dependent on prime-target stimulus onset asynchrony (Experiments 1-3) and type of target (Experiment 4). This pattern of results is attributed to the Centre-Surround mechanism proposed by Carr and Dagenbach [Carr, T. H., & Dagenbach, D. (1990). Semantic priming and repetition priming from masked words: evidence for a centre-surround attentional mechanism in perceptual recognition. Journal of Experimental Psychology: Learning, Memory and Cognition, 16, 341-350]. These results support (a) the categorical structure of semantic knowledge for famous people and (b) the application of the Centre-Surround mechanism to the domain of person recognition.

Hemispheric asymmetries in font-specific and abstractive priming of written personal names: Evidence from event-related brain potentials.

We assessed hemispheric differences in font-specific and abstractive repetition priming for famous persons' names. Participants performed speeded familiarity judgments for foveally presented famous and unfamiliar names. Famous target names were preceded by primes (150 ms) in the left or right visual field (LVF or RVF). Primes were either the same name as the target written in the same font (font-specific priming), the same name in a different font (abstractive priming), or a different name (unprimed condition). In reaction times, LH superiority was strong for abstractive priming across fonts, but was reduced to insignificance for font-specific priming. We observed 3 different ERP modulations of priming for target names: a small font-specific posterior N200 (160-220 ms), a left temporal N250r (220-300 ms), and an N400 modulation (300-500 ms). The left temporal N250r exhibited large and abstractive priming for RVF primes, but smaller and font-specific priming for LVF primes. N400 effects were observed in all priming conditions. With respect to previous findings that N200, N250r, and N400 reflect facilitation at the levels of font-specific encoding, lexical entries for names, and semantic processing, respectively, these findings suggest that the LH superiority for name processing is particularly pronounced for the access to abstractive lexical entries for written names, a process that may be mediated by the left fusiform cortex.

Better the devil you know? Nonconscious processing of identity and affect of famous faces.

The nonconscious recognition of facial identity was investigated in two experiments featuring brief (17-msec) masked stimulus presentation to prevent conscious recognition. Faces were presented in simultaneous pairs of one famous face and one unfamiliar face, and participants attempted to select the famous face. Subsequently, participants rated the famous persons as "good" or "evil" (Experiment 1) or liked or disliked (Experiment 2). In Experiments 1 and 2, responses were less accurate to faces of persons rated evil/disliked than to faces of persons rated good/liked, and faces of persons rated evil/disliked were selected significantly below chance. Experiment 2 showed the effect in a within-items analysis: A famous face was selected less often by participants who disliked the person than by participants who liked the person, and the former were selected below chance accuracy. The within-items analysis rules out possible confounding factors based on variations in physical characteristics of the stimulus faces and confirms that the effects are due to participants' attitudes toward the famous persons. The results suggest that facial identity is recognized preconsciously, and that responses may be based on affect rather than familiarity.

The role of context in remembering familar persons: insights from semantic dementia.

Semantic dementia (SD) is a progressive condition characterized by an insidious and gradual breakdown in semantic knowledge. Patients suffering from this condition gradually lose their knowledge of objects and their attributes, concepts, famous persons, and public events. In contrast, these patients maintain a striking preservation of autobiographical memory. The aim of the present study was to examine in a patient suffering from SD the role of context in the ability to recall knowledge of familiar persons. In an experiment, patient J.M. was asked to name and identify familiar persons that appeared on family photographs from recent and remote periods of her life. In the first experimental condition, the pictures represented personally familiar persons present in a specific spatial and temporal context. In a second experimental condition, the pictures showed personally familiar persons who were presented without any specific episodic context. Results indicate that the patient was able to name and identify familiar persons irrespective of the context of presentation (with/without context) and of the time period (recent/remote). No temporal gradient was found using family photographs. Finally, in contrast with familiar persons, J.M. presented a severe anomia for celebrities. Results are discussed in light of recent research in the field.

Strength of visual percept generated by famous faces perceived without awareness: effects of affective valence, response latency, and visual field.

Participants who were unable to detect familiarity from masked 17 ms faces (Stone and Valentine, 2004 and Stone and Valentine, in press-b) did report a vague, partial visual percept. Two experiments investigated the relative strength of the visual percept generated by famous and unfamiliar faces, using masked 17 ms exposure. Each trial presented simultaneously a famous and an unfamiliar face, one face in LVF and the other in RVF. In one task, participants responded according to which of the faces generated the stronger visual percept, and in the other task, they attempted an explicit familiarity decision. The relative strength of the visual percept of the famous face compared to the unfamiliar face was moderated by response latency and participants' attitude towards the famous person. There was also an interaction of visual field with response latency, suggesting that the right hemisphere can generate a visual percept differentiating famous from unfamiliar faces more rapidly than the left hemisphere. Participants were at chance in the explicit familiarity decision, confirming the absence of awareness of facial familiarity.

[A case of predominantly right-temporal lobe atrophy with disturbance of identifying familiar faces].

A right-handed 72-year-old man (I.K.) who complained of difficulty identifying familiar faces was investigated on a series of tests of face perception (face matching, recognition of age and sex, and meaning of facial expressions), facial identity (faces of families and famous persons as retrograde ones and his doctor's faces as anterograde ones) and other neuropsychological abilities. His scores of face perception tests were normal or mildly disturbed. His memory performances measured with WMS-R and Rey-Osterrieth figure were normal. But he could identify none of anterograde and retrograde faces and failed to experience any familiarity with those faces. In addition, he could not recognize none of voices of family members and a doctor, despite of being able to recognize about the age and sex of voice. On the other hand, he could describe personalities of his family members and doctors, but knew none of famous people. Memory for personal events in the recent and remote past was well preserved, while that for social events was severely disturbed in both past. In addition to impairment of identification of familiar faces, he had severe problems with identifying famous common buildings and animals. He also presented Gogi (word meaning) aphasia and impairment of semantic memory for some common objects. Tyrrell et al. reported a similar case and McNeil et al. examined the patient on covert recognition of face in detail. On their task, he showed no covert effects and they attributed the result to impairment of face recognition units themselves. Their way of thinking seems to give an explanation of I.K.'s disturbance of anterograde and retrograde memory for faces.(ABSTRACT TRUNCATED AT 250 WORDS)

[Archeology in medicine: digging up into the tophi of Popes, Dukes and Kings].

According to an Anglo-Saxon pun, "gout is the king of diseases and the disease of Kings". In fact, it is well-known that in past times a quantity of famous persons, including Kings and Popes, were affected with this rheumatic disorder. In this paper biographical anecdotes on several Popes (Pius III, Julius II, Julius III, Clement VIII, Innocent XI, Clement XII and Pius VIII), King George IV and Queen Anne of England, as well as on some members of the Lorraine lineage, all suffering from gout, are sketched out. These historical data are briefly discussed in relation to the celebrated Hippocrates's aphorisms on gout.

An ERP study of famous face incongruity detection in middle age.

Age-related changes in famous face incongruity detection were examined in middle-aged (mean = 50.6) and young (mean = 24.8) subjects. Behavioral and ERP responses were recorded while subjects, after a presentation of a "prime face" (a famous person with the eyes masked), had to decide whether the following "test face" was completed with its authentic eyes (congruent) or with other eyes (incongruent). The principal effects of advancing age were (1) behavioral difficulties in discriminating between incongruent and congruent faces; (2) a reduced N400 effect due to N400 enhancement for both congruent and incongruent faces; (3) a latency increase of both N400 and P600 components. ERPs to primes (face encoding) were not affected by aging. These results are interpreted in terms of early signs of aging.

[Artistic creativity and bipolar mood disorder].

BACKGROUND: Several studies and theories propose a connection between psychopathology and artistic creativity i.e. madness and genius characters share common roots. OBJECTIVE: Employing scientific research data, the objective of this review is to elucidate the frequency of psychopathological alterations among writers and artists and to analyse the possible influence of bipolar mood disorder spectrum on the artistic creativity. METHOD: Reviewing studies a) on retrospective investigations, based on biographies of famous persons with high creative achievements, b) on psychiatric examinations of living writers and artists, c) on individual examples of geniuses in the light of their mental status and work output correlations, and d) on creative traits and skills of diagnosed psychiatric patient populations. RESULTS: Beyond the practical experiences and impressions being held for ages from ancient times, the scientific observations and surveys indicate that psychopathological symptoms, especially those belonging to the bipolar mood disorder (bipolar I and II), major depression and cyclothymia categories occur more frequently among writers, poets, visual artists and composers, compared to the rates in the general population. Self-reports of writers and artists describe symptoms in their intensively creative periods which are reminiscent and characteristic of hypomanic states. Further, cognitive styles of hypomania (e.g. overinclusive thinking, richness of associations) and originality-prone creativity share many common as indicated by several authors. Among the eminent artists showing most probably manic-depressive or cyclothymic symptoms were: E. Dickinson, E. Hemingway, N. Gogol, A. Strindberg, V. Woolf, Lord Byron (G. Gordon), J. W. Goethe, V. van Gogh, F. Goya, G. Donizetti, G. F. Händel, O. Klemperer, G. Mahler, R. Schumann, and H. Wolf. Based on biographies and other studies, brief descriptions are given in the present article on the personality character of Gogol; Strindberg, Van Gogh, Händel, Klemperer, Mahler, and Schumann. Further example is the enigmatic silence and withdrawal from opera composing of Gioacchino Rossini (1792-1868), which is still a matter of various theories and explanations. Until his life of 37 years he composed 39 operas and lived almost another 40 years without composing any new one. Biographies show that severe depressive sufferings played a role in that withdrawal and silence, while in his juvenile years most probably hypomanic personality traits contributed to the extreme achievements and very fast composing techniques. Analysing the available biographies of Rossini and the character of music he composed (e.g. opera buffa, Rossini crescendo) strongly suggests the medical diagnosis of a bipolar affective illness. CONCLUSION: Comparing to the general population, bipolar mood disorder is highly overrepresented among writers and artists. The cognitive and other psychological features of artistic creativity resemble many aspects of the hypomanic symptomatology. It may be concluded that bipolar mood traits might contribute to highly creative achievements in the field of art. At the same time, considering the risks, the need of an increased medical care is required.

[Not Available].

The investigation of Lenin's brain by the German neurobiologist Oskar Vogt from Berlin and his Russian collaborators in Moscow is one of the most exciting and simultaneously oddest chapters in the history of medicine. With the bizarre claim to be able to detect the material substrate of genius it provoked as much unrealistic expectations in the public as strong criticism by the scientific community of brain researchers. The present paper deals in a brief survey with the history of collecting and measuring the brains of famous persons in general and particularly with the historical, political and social circumstances of the performed investigation of Lenin's brain. In this connection the epistemological and technical prerequisites of architectonical brain research and its means of the topographical representation of complex histo-anatomical and physiological differences in the brain cortex are shortly discussed. The opening of Russian archives after the socio-economic turn of the year 1991 brought up new background facts in Lenin's pathobiography; together with the sources from German archives a rather extensive reconstruction of the historical events between Lenin's death in 1924 and the final report of the Moscow Brain Research Institute (Institute Mozga) to the Politburo of the Russian Communist Party (Bolsheviki) in 1936 is possible now.

Recognizing famous voices: influence of stimulus duration and different types of retrieval cues.

The current investigation measured the effects of increasing stimulus duration on listeners' ability to recognize famous voices. In addition, the investigation studied the influence of different types of cues on the naming of voices that could not be named before. Participants were presented with samples of famous and unfamiliar voices and were asked to decide whether or not the samples were spoken by a famous person. The duration of each sample increased in seven steps from 0.25 s up to a maximum of 2 s. Voice recognition improvements with stimulus duration were with a growth function. Gains were most rapid within the first second and less pronounced thereafter. When participants were unable to name a famous voice, they were cued with either a second voice sample, the occupation, or the initials of the celebrity. Initials were most effective in eliciting the name only when semantic information about the speaker had been accessed prior to cue presentation. Paralleling previous research on face naming, this may indicate that voice naming is contingent on previous activation of person-specific semantic information.

Human brain potential correlates of repetition priming in face and name recognition.

We investigated repetition priming in the recognition of famous people by recording event-related brain potentials (ERPs) and reaction times (RTs). Participants performed speeded two-choice responses depending on whether or not a stimulus showed a famous person. In Experiment 1, a facilitation was found in RTs to famous (but not to unfamiliar) faces when primed by the same face shown in an earlier priming phase of the experiment. In ERPs, an influence of repetition priming was observed neither for the N170 nor for a temporal N250 component which in previous studies had been shown to be sensitive to immediate face repetitions. ERPs to primed unfamiliar faces were more negative over right occipitotemporal areas than those to unprimed faces, but this effect was specific for repetitions of the same image, consistent with recent findings. In contrast, ERPs to primed familiar faces were more positive than those to unprimed faces at parietal sites from 500-600 ms after face onset, and these priming effects were comparable regardless of whether the same or a different image of the celebrity had served as prime. In Experiment 2, similar results were found for name recognition-a facilitation in RTs to primed familiar but not unfamiliar names, and a parietal positivity to primed names around 500-600 ms. ERP repetition effects showed comparable topographies for faces and names, consistent with the idea of a common underlying source. With reference to current models of face recognition, we suggest that these ERP repetition effects for familiar stimuli reflect a change in post-perceptual representations for people, rather than a neural correlate of recognition at a perceptual level.

Slowly progressive defect in recognition of familiar people in a patient with right anterior temporal atrophy.

We report the case of a patient (C.O.) who showed a selective defect in the recognition of familiar people, with very mild disease progression during a period of 30 months resulting from focal atrophy of the right temporal lobe. On formal neuropsychological testing, C.O. obtained high scores on tests of general intelligence, episodic memory, language, executive functions, selective attention, visual recognition and visual-spatial abilities. On more specific tasks of familiar and unfamiliar face recognition, C.O. scored above the controls' means on perceptual tests, but obtained highly pathological results on amnesic-associative tests. His disorder of recognition of familiar people was not due to loss of person-specific information, since he obtained highly abnormal naming scores when presented with photographs of famous people but borderline or mildly abnormal scores in a tasks in which he had to name celebrities from verbal definitions. On the other hand, C.O.'s recognition disorder could not be considered to be a form of 'associative prosopagnosia' since a similar defect was observed when he was requested to access information about famous persons through their voice rather than their face. Two alternative interpretations are advanced to explain C.O.'s inability to access his relatively spared person-specific knowledge not only through the person's face but also through the person's voice. The first hypothesis is that, before accessing the person-specific information, unimodal recognition channels must converge into a multimodal, non-verbal person-recognition system and that the right anterior temporal cortices play a crucial role in this integrative activity. The second hypothesis is that the face-recognition units have privileged access to person-specific semantic knowledge and that other recognition subsystems require coactivation of the face-recognition units in order to access person-specific semantic information.

A metamemory perspective on odor naming and identification.

A metacognitive perspective is utilized to elucidate why it is so difficult to name common odors and what characterizes the subjective knowledge people have about their actual odor knowledge. Odor-naming failures are often accompanied by strong feelings of knowing (FOK) or feelings of imminent retrieval of what it is that smells. The paper's two experiments investigate FOK judgements and tip of the tongue (TOT) experiences for odor and person names. The data indicate that our inability to correctly name odors are typically not due to the often proposed uniquely poor association between odors and their proper names, but rather due to failures to identify the odors, that is, failures to know 'what it is'. It was also found that (i) TOT experiences are very unusual for odor names and more so than for person names; (ii) FOK judgements about odor names are significantly less predictive of later retrieval than equivalent judgements about names of persons; (iii) FOK judgements were highly correlated with the familiarity of the cue (odor or picture of famous person), rendering some support for the idea that FOK judgements are based on the perceived familiarity of the cue triggering the FOK; and (iv) the idea that FOK judgements are based on the amount of available information about the sought-for memory (accessibility theory) was also supported.

The right temporal lobe variant of frontotemporal dementia: cognitive and neuroanatomical profile of three patients.

The right temporal variant of frontotemporal lobar degeneration (Rtv-FTLD) is a focal degenerative condition affecting predominantly the right temporal lobe. The aim of this study was to further characterize the profile of cognitive impairment and the neuroanatomical basis of Rtv-FTLD patients without behavioural disturbances. A group of three patients with this syndrome had a detailed neuropsychological assessment, along with Voxel-Based Morphometry (VBM) of their brain to determine location of cortical atrophy. VBM analyses showed a pattern of atrophy that was predominant in the right hemisphere and concerned primarily the right anterior temporal lobe region. Patients carried out a test of famous people in which their ability to recognize, name and provide semantic information about famous persons from their faces, their voices and their names was investigated. They all showed a severe defect in recognizing, naming and identifying famous people irrespective of modality. Therefore, their inability to recognize famous people resulted from a multimodal defect (semantic). These results highlight the semantic nature of the defect, and suggest that the anterior right temporal lobe may have a prominent role in processing person-based semantic knowledge. This study helps in further understanding the neuropsychological profile of patients with Rtv-FTLD.
