We live in a celebrity-obsessed world and our medical students are no more immune to the glamour of celebrity than anyone else. When teaching medical students about a certain medical illness I used to tell them about a celebrity who suffers from this illness. I did this to get their attention and to stimulate their interest but even though the celebrity's information was already in the public domain I started to feel increasingly uncomfortable about doing this. Celebrities are famous but they have a right to a private life as much as everybody else. I began to feel that I was invading the celebrity's privacy by discussing his illness in a lecture hall. I could have asked for his consent to our discussing his confidential medical information but this would probably have been impracticable and in any case such consent would have been invalid as he would not know in advance what the discussion would be about. I could not argue that discussing his illness was overwhelmingly in the public interest or that I could not make my teaching points in any other way. I may have considered it reasonable to discuss the information but that is no guarantee that he would have felt the same way. I think that using famous people's illnesses to make a point does them no good and can do them harm: it is also breaches their right to have a private life.

Exploring the functional architecture of person recognition system with event-related potentials in a within- and cross-domain self-priming of faces.

In this paper, we explored the functional properties of person recognition system by investigating the onset, magnitude, and scalp distribution of within- and cross-domain self-priming effects on event-related potentials (ERPs). Recognition of degraded pictures of famous people was enhanced by a prior exposure to the same person's face (within-domain self-priming) or name (cross-domain self-priming) as compared to those preceded by neutral or unrelated primes. The ERP results showed first that the amplitude of the N170 component to famous face targets was modulated by within- and cross-domain self-priming, suggesting not only that the N170 component can be affected by top-down influences but also that this top-down effect crosses domains. Second, similar to our behavioral data, later ERPs to famous faces showed larger ERP self-priming effects in the within-domain than in the cross-domain condition. In addition, the present data dissociated between two topographically and temporally overlapping priming-sensitive ERP components: the first one, with a strongly posterior distribution arising at an early onset, was modulated more by within-domain priming irrespective whether the repeated face was familiar or not. The second component, with a relatively uniform scalp distribution, was modulated by within- and cross-domain priming of familiar faces. Moreover, there was no evidence for ERP-induced modulations for unfamiliar face targets in the cross-domain condition. Together, our findings suggest that multiple neurocognitive events that are possibly mediated by distinct brain loci contribute to face priming effects.

Some famous persons with visual problems as shown on postage stamps.

A number of persons important in all fields of human endeavor became blind or were born blind. The reason for the loss of vision varies a great deal, but many of them continued a productive life and contributed to the welfare and advancement of mankind. It is also surprising how many famous people lost one eye or lost nearly all vision in one eye. These were not only soldiers and warriors exposed to accidental traumas, but also writers, scientists and even physicians.

Remembering and forgetting of semantic knowledge in amnesia: a 16-year follow-up investigation of RFR.

We report our long-term follow-up investigations of RFR, a post-encephalitic case of very grave anterograde and retrograde amnesia. We also describe the results of quantitative neuroimaging of his brain injury that showed bilateral and severe reduction in the hippocampal formation and medial temporal structures with sparing of left lateral/posterior and right posterior temporal cortex. We established that RFR had a persistent severe anterograde and retrograde amnesia for personal and public events. His personal semantic knowledge was relatively spared for the retrograde period. There was a modest and global reduction in RFR's vocabulary for words acquired in adulthood before he became amnesic but there was no evidence of any retrograde gradient. His retrograde knowledge of people was also without any gradient. Remarkably, there had been no change in the extent of his semantic knowledge across a prolonged re-test interval indicating that the loss of semantic knowledge was stable and likely to have arisen at the time of his initial lesion. RFR also showed evidence of a limited but significant ability to acquire new word meanings and a more restricted capacity for learning about new celebrities. While he was able to demonstrate face and name familiarity for newly famous people, he was unable to provide much semantic detail. RFR's amnesia can be partially explained by contemporary theories that allow for parallel cortical and hippocampal memory systems but is difficult to reconcile in detail with any extant view.

Will Julia Roberts harm Nicole Kidman? Semantic priming effects during face naming.

Three experiments are reported, which examine whether face naming is vulnerable to semantic competition in a similar way to object naming. Previous experiments with object naming have shown that a related prime picture presented 3 trials before a target picture results in an increase in error rate and naming latencies when compared to unrelated prime conditions. The experiments here use the same paradigm, with errors as the main dependent variable. In Experiment 1, the prime and target faces were from the same occupational category (e.g., politicians, actors), and in Experiment 2, the primes and target faces were also associated to each other. In Experiment 3, the prime was presented as a name to be read aloud. Unrelated filler stimuli intervened between prime and target. In all experiments, there was a reduction in target-naming errors in the related conditions, and in Experiment 3 this was shown to be largely a reduction in naming failures. The results suggest that related name representations for famous people are not activated in parallel and in competition, and that there is some evidence for a relatively long lasting facilitatory effect. These results require some modification to any serial account of face naming to differentiate it from the generally well-established serial account of object naming.

The contribution of autobiographical significance to semantic memory.

We examined the importance of autobiographical significance (AS) in the representation and organization of semantic memory by examining which famous people are most likely to be associated with specific personal memories and whether or not this AS can be distinguished from other factors, such as familiarity. Norming studies with 45- to 55-year-old and 65- to 80-year-old participants suggested that AS is distinct from familiarity and that it interacts closely with emotional salience. Furthermore, in a set of experiments, we tested the hypothesis that AS is an important organizing principle in long-term episodic and semantic memory by contrasting performances on tests of recall, recognition, fame judgment, and speeded reading for famous names judged to be of either high or low personal relevance. Participants demonstrated a performance advantage (i.e., enhanced memory and faster responding) for autobiographically significant famous names, regardless of whether their own judgments or others' judgments were used to classify the names. The implications of these findings for models of semantic memory are discussed.

Selective preservation of memory for people in the context of semantic memory disorder: patterns of association and dissociation.

A number of single cases in the literature demonstrate that person-specific semantic knowledge can be selectively impaired after acquired brain damage compared with that of object categories. However, there has been little unequivocal evidence for the reverse dissociation, selective preservation of person-specific semantic knowledge. Recently, three case studies have been published which provide support for the claim that such knowledge can be selectively preserved [Kay, J., & Hanley, J. R. (2002). Preservation of memory for people in semantic memory disorder: Further category-specific semantic dissociation. Cognitive Neuropsychology, 19, 113-134; Lyons, F., Hanley, J. R., & Kay, J. (2002). Anomia for common names and geographical names with preserved retrieval of names of people: A semantic memory disorder. Cortex, 38, 23-35; Thompson, S. A, Graham, K. S., Williams, G., Patterson, K., Kapur, N., & Hodges, J. R. (2004). Dissociating person-specific from general semantic knowledge: Roles of the left and right temporal lobes. Neuropsychologia, 42, 359-370]. In this paper, we supply further evidence from a series of 18 patients with acquired language disorder. Of this set, a number were observed to be impaired on tests of semantic association and word-picture matching using names of object categories (e.g. objects, animals and foods), but preserved on similar tests using names of famous people. Careful methodology was applied to match object and person-specific categories for item difficulty. The study also examined whether preservation of person-specific semantic knowledge was associated with preservation of knowledge of 'biological categories' such as fruit and vegetables and animals, or with preservation of 'token' knowledge of singular categories such as countries. The findings are discussed in the context of a variety of accounts that examine whether semantic memory has a categorical structure.

Preservation of famous person knowledge in a patient with severe post anoxic amnesia.

A 58 year old patient (ES) suffered severe anterograde and retrograde amnesia following prolonged cardiac arrest with presumed hypoxic brain damage. Personally relevant autobiographical memory was severely impaired as was knowledge of public events. In contrast, knowledge of famous people was very well preserved. This findings has implications for the organisation of remote memory. Knowledge of people is clearly represented independently from autobiographical memory. We argue that this pattern of profound autobiographical amnesia may result from either multifocal neocortical damage (as in this case) or a failure of the "thematic framework" system involved in the active reconstruction of autobiographical memory, as hypothesised in another patient with thalamic infarction who showed a similar pattern of results (Hodges and McCarthy, 1993).

Repetition priming from incomplete faces: evidence for part to whole completion.

Two experiments are reported in which subjects' reaction times to make familiarity decisions to the faces of famous people were compared for faces primed by previously seeing (1) the internal features of the same face, (2) the external features of the same face, or (3) a complete version of the same face. Reaction times to faces primed by the internal features, the external features or a complete face were significantly facilitated relative to an 'unprimed' comparison condition, and did not differ one from another. Viewing part of a familiar face on a previous occasion was therefore found to be as effective at priming recognition as seeing a whole face. This finding was demonstrated in Expt 1 for priming from the repetition of stimuli derived from an identical photograph of the same famous person, and in Expt 2 for priming from stimuli derived from a different photograph of the same familiar face. 'Distributed processing' accounts of repetition priming may be more useful than accounts based entirely on episodic records in explaining these results.

Access to visual information from a name is contingent on access to identity-specific semantic information.

In this study, we investigated subjects' ability to retrieve information about a familiar person's facial appearance in response to seeing their name. Each famous name was associated with one of four occupations (sport, music, politics, and acting) and one of four distinctive facial features (beard, long hair, glasses, baldness). Subjects were asked to state which occupation, and which facial feature was associated with each name. The most important finding was that subjects were generally only able to recall the distinctive facial feature that a person possessed if they were also able to recall their occupation. Recall of the person's occupation, by contrast, was not contingent on remembering the person's facial appearance. These results suggest that there are no direct links between the representation of a person's name in memory and visual information about their facial appearance. The link appears to be indirect, and to be mediated by non-visual semantic information about the person, such as their occupation. This conclusion was also supported by an examination of the effects of biographical cues on subjects' ability to recall facial information that they had previously failed to recall. In a second experiment, subjects were presented with biographical details about famous people, and were asked to retrieve information about their face and name. Retrieval of facial information did not appear to be contingent on recall of the name, nor did recall of the name appear to be contingent on retrieval of facial information. On the basis of the results, an hierarchical model of name recognition is presented which is analogous to current models of face recognition (e.g. Bruce & Young, 1986).

Measuring the importance of attributes that influence consumer attitudes to colorectal cancer screening.

BACKGROUND: The aim of the present study was to rate the importance of attributes of screening for bowel cancer. METHOD: Randomly selected households in central Sydney were contacted to identify men and women aged 50-70 years who were then asked to complete a self-administered questionnaire about bowel cancer screening and related issues. Seven hundred and ninety-one residents (362 men and 429 women) returned questionnaires. Respondents were asked to rate the extent to which each of 34 attributes would encourage them to participate in bowel cancer screening. RESULTS: The three most highly rated attributes were: if the test was recommended by their general practitioner (GP; 94% either 'strongly agreed' or 'agreed'); if the test identified early cancers (92%); and if the test would avert a premature death due to bowel cancer (90%). Having a friend or relative with bowel cancer (61%), advertising (41%) or famous people promoting the program (62%) were less influential. Respondents who were unemployed or on a pension were less likely to participate in screening than those who were employed if there was an 'out of pocket' charge of 15.00 Australian dollars (chi 2 = 7.56, 2df, P = 0.006). Respondents with higher levels of education were significantly more concerned than respondents with lower levels of education about test accuracy (chi 2 = 15.76, 2df, P < 0.001), its availability from their local chemist (chi 2 = 16.96, 2df, P < 0.001), being able to return the test kit by post (chi 2 = 21.9, 2df, P < 0.001) or deposit it with their local chemist (chi 2 = 10.0, 2df, P < 0.01). They were also less likely to be influenced by a famous person promoting bowel cancer screening (chi 2 = 18.87, 2df, P < 0.001). CONCLUSIONS: Our results endorse the role of the GP in bowel cancer screening. However, the study also has demonstrated that test accuracy, the convenience of the screening service and notification of test results are valued differently by subgroups in the community, according to their level of education.

Can the famous really postpone death?

David P. Phillips has reported evidence that famous people are often able to postpone their deaths until after a birthday. A reexamination of Phillips' data shows some aspects of his analysis to be questionable, including the lumping together of deaths that occur during the birthmonth, which does not distinguish deaths that occurred before the birthday from those that occurred afterward. A reanalysis of his data shows that there were actually a relatively large number of deaths in the month preceding and the months following the birthday. One explanation is that the anxiety associated with this milestone and the excesses associated with its celebration are sometimes fatal. Another explanation is that Phillips' results were a fluke created by a selective use of data.

Removing eyebrows impairs recognition of famous faces, or doesn't, depending on how the eyebrows are removed.

Matching photos of famous people's faces with their names was as fast with photos that had eyebrows masked by adhesive plaster as with unretouched original photos. But matching was slower with photos that had eyebrows erased and replaced with adjacent skin texture and colour than with original photos. The conjecture that erasure impairs recognition because it alters a face's configuration was examined by repeating the experiment with the photos shown upside down, the rationale being that because configural information is difficult to encode from inverted faces the erasure effect should diminish. With inverted faces, matching was no different for original, eyebrows-masked, and eyebrows-erased photos. Eyebrows appear to be less important for face recognition as informative parts and features than as sources of information about a face's configuration.

[The pathography of Dostoyevsky or the dangers of being the Father of the Idiot].

The widespread genre of pathography, or medical biographies of famous people, may be interpreted as a case of stigmatisation. It has been suggested by proponents of the idea of stigmatisation that, by labelling geniuses "mentally ill", psychiatrists advanced their own interest and gained prestige for their own profession. Though this explanation may sound plausible, it appears too schematic to match a more sophisticated reality. The use of medical diagnosis, which doctors applied to celebrities, may appear to stigmatise, but the motives and consequences of writing medical biographies were undoubtedly more various than the enhancement of narrow medical interests. Besides doctors and their supposed victims, the practice of pathography involved other interested parties including literary critics, educators and the lay public. This was the case of the nineteenth-century pathographies of Dostoyevsky, when, suggesting that the writer was mentally ill, psychiatrists followed into the critics' steps.

Biographical knowledge: modality-specific or modality-neutral?

A number of patients have been reported who produce more semantic information in response to faces than to names, and vice versa (e.g., Eslinger et al., 1996). It has sometimes been claimed that these patterns are consistent with the hypothesis that faces and names gain access to separate, modality-specific, biographic knowledge systems. Resolving this debate has proved somewhat difficult, however, given limitations of existing data. Not only are there relatively few patients showing these particular patterns of differentiation, but also testing has often not been sufficiently thorough to rule out alternative accounts. In this paper, we present results of two studies investigating biographical knowledge differences in neurological patients and healthy adult controls. The first study focused on two patients who appeared to access more information about famous people in response to their names than to their faces. On superficial analysis, this pattern could be seen to support the notion of modality-specific biographical knowledge systems. However, closer examination revealed that, for both cases, the findings could be explained by a difficulty in face recognition, rather than by assuming separate semantic representations for faces and names. The second study investigated the role of face and name cues in accessing biographical information in younger and older healthy adults. We found that accuracy in retrieval of biographical information was significantly better with name cues for both groups. Results from these studies not only highlight the processes that must be examined in order to demonstrate modality-specific differences conclusively, but also reveal a fundamental bias in retrieval of biographical knowledge that has not been addressed in research of this nature.

Temporal gradients in the retrograde amnesia of patients with alcoholic Korsakoff's disease.

Eleven alcoholic patients with Korsakoff's disease and 15 control subjects were given three tests of retrograde amnesia. The first consisted of photographs of famous faces from the past, the second was a recall test of famous people and events, and the third was a multiple-choice questionnaire. To determine whether previously reported temporal gradients (ie, preservation of remote events) were related to item difficulty, half of the questions dealt with events of transient fame while half concerned subjects that continued to receive public attention for many years. The findings indicate that alcoholic patients with Korsakoff's disease have a marked retrograde amnesia that is characterized by a steep temporal gradient, and that this gradient is not an artifact due to the difficulty of the questions or the method of testing.

A case of simulated, psychogenic or focal pure retrograde amnesia: did an entire life become unconscious?

A case of pure retrograde amnesia following mild head injury is reported. Neuropsychological, psychodynamic and statistical approaches are employed in an attempt to disentangle the clinical picture presented by the patient. Focal retrograde amnesia, psychogenic retrograde amnesia and simulated amnesia are all taken into account. From a public events questionnaire and an inquiry about famous people, consistency analyses showed that the patient was able implicitly to use information she denied having, but at the same time, made us lower the probability of a simulated amnesia. Moreover, psychodynamic analysis showed that the patient's personality structure was compatible with hysterical patterns and we suggest that the patient's memory defect may be related to her personality. It seems less likely, though still possible, that the case may be explained in terms of deliberate simulation. In this case we conclude that the classification along the conscious/unconscious dimension seems more informative than the contrast between psychogenic and organic genesis.

Remembrance of Hans Goldmann, 1899-1991.

Professor Hans Goldmann died in Bern on November 19th, 1991 at the age of 92 years. His outstanding intellectual capacity was discovered at an early age and demonstrated throughout his life. He was appointed as teaching assistant of the famous A. Cermak von Seysenegg, Chairman of the Institute of Physiology of the German Charles University in Prague. During his stay at the University of Prague, he was influenced by the famous people of his time, such as Einstein (physicist), Mach (physicist and psychophysicist), Lorenz (behavioral scientist), Popper (philosopher), Schlick (physicist and philosopher), Hering (physiologist), and others. Goldmann absorbed the essence of these disciplines to a very large extent. This, together with his remarkable intellect, enabled him to produce outstanding research work within a large spectrum of sciences more or less directly related to ophthalmology. Goldmann became known in particular for his exceptional and fundamental work on perimetry and glaucoma and he managed to cast his basic insight into practical, easy-to-operate, high-precision diagnostic instruments which, several decades after their invention, are still used by every ophthalmologist. He will enter history as one of the very great pioneers in ophthalmology.
