Abstract/Results: RESULTS:
Several tests of frontal lobes functions were administered: Wisconsin Card Sorting Test, Tower of London, visual working memory task, and verbal fluency. Other tests assumed to rely on temporal lobe function were administered as well: verbal paired-associates and visual recognition.
The measure of verbal reality-monitoring deficit was strongly associated with hallucinations. It was also correlated with measures of frontal deficit (wisconsin perseverative errors: r = .32, p <.08; perseverative errors in visual search: .37, p <. 05; planning errors in the Tower of London: r = .42, p <.025). By contrast, the measure of verbal memory efficiency that did not involve any reality-monitoring function was not correlated with any of these frontal measures, which shows the specificity of the association with reality-monitoring deficit, rather than memory deficit. The measure of verbal reality-monitoring deficit was also associated with one measure of temporal lobe deficit (visual recognition: -.43, p < .025).
The measure of visual reality-monitoring deficit was associated with visual hallucinations. It was not correlated at all with any frontal measure. However, it was correlated with one measure of temporal lobe deficit (visual recognition: r = -.39, p < 05). By contrast, the measure of visual memory efficiency that did not involve any reality-monitoring function was not correlated with this temporal lobe measure. This suggests that it is actually the confusion between reality and imagination that is involved in this association with temporal dysfunction, rather than a mere deficit in visual memory.

Semantic organization and verbal memory efficiency in patients with schizophrenia

Abstract/Results: ABSTRACT:
The role of semantic organization in verbal memory efficiency in schizophrenia was investigated. Patients and healthy controls were administered a free-recall task involving 1 nonsemantically organizable list, 1 list organizable in semantic categories with typical instances, and 1 list organizable in semantic categories with atypical instances. Reduced semantic organization was observed in patients. Regression analyses showed that the semantic clustering score in the atypical organizable list made a significant contribution to recall performance in patients. When semantic clustering was controlled, the effect of diagnosis on free recall was significant. These results suggest that depth of semantic organization is a crucial factor of verbal memory performance in schizophrenia. However, semantic organizational deficit does not account for the whole recall impairment.

Abstract/Results: ABSTRACT:
Verbal and visual recognition tasks were administered to 40 patients with schizophrenia and 40 healthy comparison subjects. The verbal recognition task consisted of discriminating between 16 target words and 16 new words. The visual recognition task consisted of discriminating between 16 target pictures (8 black-and-white and 8 color) and 16 new pictures (8 black-and-white and 8 color). Visual recognition was followed by a spatial context discrimination task in which subjects were required to remember the spatial location of the target pictures at encoding. Results showed that recognition deficit in patients was similar for verbal and visual material. In both schizophrenic and healthy groups, men, but not women, obtained better recognition scores for the colored than for the black-and-white pictures. However, men and women similarly benefited from color to reduce spatial context discrimination errors. Patients showed a significant deficit in remembering the spatial location of the pictures, independently of accuracy in remembering the pictures themselves. These data suggest that patients are impaired in the amount of visual information that they can encode. With regards to the perceptual attributes of the stimuli, memory for spatial information appears to be affected, but not processing of color information.

Word frequency effects on free recall and recognition in patients with schizophrenia

Abstract/Results: ABSTRACT:
BACKGROUND:
Word frequency paradigms have been used repeatedly in healthy populations to help understand the functioning of verbal memory. We investigated the word frequency effects in a sample of patients with schizophrenia, assuming these data may shed light on certain encoding processes.
METHODS:
Two mixed lists of high- and low-frequency words were presented to 46 patients with schizophrenia and 43 healthy control subjects. List learning was followed by free recall and recognition in immediate and delayed conditions.
RESULTS:
Overall the high-frequency words were better recalled, whereas the low-frequency words were better recognised. The lack of interaction with diagnosis indicates that these effects were equivalent in both groups. In immediate recognition, the discrimination deficit for the high-frequency words in patients tended to be increased relative to that for the low-frequency words, suggesting greater impairment in the encoding of those words.
CONCLUSION:
It is argued that the encoding of the distinct low-frequency words is less efficient in patients, but qualitatively unimpaired. By contrast, the familiar words might be more difficult for patients to encode, as they are more easily confused with other common words stored in long-term memory.

Abstract/Results: ABSTRACT:
Several studies have reported an association between hallucinations and tendency to make false alarms in acoustic signal detection tasks. Previous work on patients with schizophrenia has suggested that false recognitions and other types of memory error were positively associated with hallucinations and inversely associated with certain negative symptoms of withdrawal. In this study, 40 patients with schizophrenia were administered a word recognition task. Mixed lists of high- and low-frequency words were presented, then the target words had to be recognized among distractors in immediate and delayed recognition conditions. Hallucination scores were correlated with an increased bias toward false recognitions of nonpresented words. Affective flattening tended to be correlated with a reduced bias toward false recognitions. Anhedonia was significantly correlated with a reduced response bias. Hallucinations and anhedonia therefore presented an opposite association with the response bias. The influence of word frequency and delay on this association is discussed.

Abstract/Results: ABSTRACT:
The role of slowing of processing speed in verbal memory impairment in patients with schizophrenia was investigated. Forty-one patients with schizophrenia and 41 healthy control subjects were administered a verbal memory task involving free recall of three lists of words, which varied in their degree of semantic organization. Standard processing speed tests were administered as well. Regression analyses were conducted on the number of words recalled in each list. A global processing speed measure was a significant predictor of the recall of each list in patients. Patients were very significantly impaired in the recall of the three lists relative to healthy controls. However, when the processing speed measure was entered in the regression, the significance of diagnosis was considerably reduced for one of the lists, with no semantic organization, and eliminated for the other two lists which contained semantic organization. These findings suggest that slowing in processing speed is an important contributor to verbal memory impairment in patients with schizophrenia. The possible role of various specific slowing functions is discussed.

Temporal context discrimination in patients with schizophrenia. Associations with auditory hallucinations and negative symptoms

Abstract/Results: ABSTRACT:
BACKGROUND:
A deficit in remembering the temporal context of events (a type of source memory) has been observed in schizophrenia, and suggested to be associated with positive symptoms.
Methods: In order to investigate memory for temporal context, we administered a list discrimination task to a sample of schizophrenia patients and a sample of healthy controls. Participants were required to learn two lists of mixed high- and low-frequency words separated by 10 min, then to remember whether each word had been presented in the first or in the second list.
RESULTS:
The number of misattributions to the wrong list was significantly higher in patients than in healthy controls. However, the group difference was eliminated when recall efficiency was covaried. The number of list misattributions was higher in patients with auditory hallucinations than in the other patients, independently of verbal recall efficiency. By contrast, affective flattening and anhedonia were associated with fewer list misattributions of the high-frequency words.
CONCLUSIONS:
It is suggested that auditory hallucinations are associated with deficit in processing or remembering the temporal context. Conversely, certain negative symptoms are associated with reduced temporal context errors. The possible neural mechanisms involved in temporal context deficit as well as in these specific clinical symptoms are discussed.

Abstract/Results: ABSTRACT:
Hallucinations have been found associated with false detection or false recognition of acoustic/verbal material in several studies. We investigated whether they were also linked with false recognition of pictures. Furthermore, an association between hallucinations and deficits in remembering temporal, context was observed in previous research on schizophrenia. We investigated whether the association extends to deficits in remembering spatial context. Forty-one patients with schizophrenia underwent a visual memory task. Sixteen mixed black-and-white and colored pictures were presented at different locations. Participants had to recognize the pictures among distractors, then to recall the spatial context of the presentation of the target pictures. Results showed that auditory hallucinations were associated with poor recognition of the colored pictures. When recognition efficiency and negative symptoms were statistically controlled, auditory hallucinations were also associated with increased response bias toward false recognition of nontarget pictures, and with errors in remembering the spatial context. No associations with visual hallucinations emerged. Anhedonia was associated with response bias, in the direction opposite to that of hallucinations. In conclusion, the association between hallucinations and response bias extends across modalities to picture recognition. The association between hallucinations and temporal context impairment extends to spatial context.

Abstract/Results: ABSTRACT:
OBJECTIVE:
An association between hallucinations and reality-monitoring deficit has been repeatedly observed in patients with schizophrenia. Most data concern auditory/verbal hallucinations. The aim of this study was to investigate the association between visual hallucinations and a specific type of reality-monitoring deficit, namely confusion between imagined and perceived pictures.
METHOD:
Forty-one patients with schizophrenia and 43 healthy control participants completed a reality-monitoring task. Thirty-two items were presented either as written words or as pictures. After the presentation phase, participants had to recognize the target words and pictures among distractors, and then remember their mode of presentation.
RESULTS:
All groups of participants recognized the pictures better than the words, except the patients with visual hallucinations, who presented the opposite pattern. The participants with visual hallucinations made more misattributions to pictures than did the others, and higher ratings of visual hallucinations were correlated with increased tendency to remember words as pictures. No association with auditory hallucinations was revealed.
CONCLUSIONS:
Our data suggest that visual hallucinations are associated with confusion between visual mental images and perception.

Abstract/Results: ABSTRACT:
BACKGROUND:
Previous research has demonstrated that various types of verbal source memory error are associated with positive symptoms in patients with schizophrenia. Notably, intrusions in free recall have been associated with hallucinations and delusions. We tested the hypothesis that extra-list intrusions, assumed to arise from poor monitoring of internally generated words, are associated with verbal hallucinations and that intra-list intrusions are associated with global hallucination scores.
METHOD:
A sample of 41 patients with schizophrenia was administered four lists of words, followed by free recall. The number of correctly recalled words and the number of extra- and intra-list intrusions were tallied.
RESULTS:
The verbal hallucination score was significantly correlated with the number of extra-list intrusions, whereas it was unrelated to the number of correctly recalled words. The number of intra-list intrusions was significantly correlated with the global, but not with the verbal, hallucination score in the subsample of hallucinating patients. It was marginally significantly correlated with the delusion score in delusional patients.
CONCLUSIONS:
The data corroborate the view that verbal hallucinations are linked to defective monitoring of internal speech, and that errors in context processing are involved in hallucinations and delusions.

Abstract/Results: ABSTRACT:
Previous studies have revealed semantic memory impairments in patients with schizophrenia, and suggested that certain of these impairments were related to thought disorganization. One explanation offered for this is a broadening of the boundaries of semantic categories in schizophrenia. We selected 16 semantic categories, and required a sample of 41 schizophrenia patients and 43 healthy control subjects to produce one exemplar from each category. The typicality of the subjects’ responses was rated. The exemplars produced by the patients were on average less typical than those produced by the healthy controls. No significant association between typicality of the response and thought disorganization was revealed in the patient sample. Affective flattening, alogia, and anhedonia were significantly and inversely associated with the typicality score, that is, higher ratings of these symptoms were associated with more typical responses. Our results suggest that a broadening of semantic category boundaries is observed in patients with schizophrenia, but is unrelated to thought disorganization. This semantic abnormality is not a feature of the patients with high ratings of certain negative symptoms.

Serial and semantic encoding of lists of words in schizophrenia patients with visual hallucinations

Abstract/Results: ABSTRACT:
Previous research has suggested that visual hallucinations in schizophrenia are associated with abnormal salience of visual mental images. Since visual imagery is used as a mnemonic strategy to learn lists of words, increased visual imagery might impede the other commonly used strategies of serial and semantic encoding. We had previously published data on the serial and semantic strategies implemented by patients when learning lists of concrete words with different levels of semantic organisation (Brébion et al., 2004). In this paper we present a re-analysis of these data, aiming at investigating the associations between learning strategies and visual hallucinations. Results show that the patients with visual hallucinations presented less serial clustering in the non-organisable list than the other patients. In the semantically organisable list with typical instances, they presented both less serial and less semantic clustering than the other patients. Thus, patients with visual hallucinations demonstrate reduced use of serial and semantic encoding in the lists made up of fairly familiar concrete words, which enable the formation of mental images. Although these results are preliminary, we propose that this different processing of the lists stems from the abnormal salience of the mental images such patients experience from the word stimuli.

Abstract/Results: ABSTRACT:
Previous work has suggested that decrement in both processing speed and working memory span plays a role in the memory impairment observed in patients with schizophrenia. We undertook a study to examine simultaneously the effect of these two factors. A sample of 49 patients with schizophrenia and 43 healthy controls underwent a battery of verbal and visual memory tasks. Superficial and deep encoding memory measures were tallied. We conducted regression analyses on the various memory measures, using processing speed and working memory span as independent variables. In the patient group, processing speed was a significant predictor of superficial and deep memory measures in verbal and visual memory. Working memory span was an additional significant predictor of the deep memory measures only. Regression analyses involving all participants revealed that the effect of diagnosis on all the deep encoding memory measures was reduced to non-significance when processing speed was entered in the regression. Decreased processing speed is involved in verbal and visual memory deficit in patients, whether the task require superficial or deep encoding. Working memory is involved only insofar as the task requires a certain amount of effort.

Abstract/Results: ABSTRACT:
The role of various types of slowing of processing speed, as well as the role of depressed mood, on each stage of verbal memory functioning in patients diagnosed with schizophrenia was investigated. Mixed lists of high- and low-frequency words were presented, and immediate and delayed free recall and recognition were required. Two levels of encoding were studied by contrasting the relatively automatic encoding of the high-frequency words and the more effortful encoding of the low-frequency words. Storage was studied by contrasting immediate and delayed recall. Retrieval was studied by contrasting free recall and recognition. Three tests of motor and cognitive processing speed were administered as well. Regression analyses involving the three processing speed measures revealed that cognitive speed was the only predictor of the recall and recognition of the low-frequency words. Furthermore, slowing in cognitive speed accounted for the deficit in recall and recognition of the low-frequency words relative to a healthy control group. Depressed mood was significantly associated with recognition of the low-frequency words. Neither processing speed nor depressed mood was associated with storage efficiency. It is concluded that both cognitive speed slowing and depressed mood impact on effortful encoding processes.

Abstract/Results: ABSTRACT:
Previous research had shown that processing speed and premorbid IQ are predictors of verbal-memory efficiency in patients with schizophrenia. We investigated whether the same factors are involved in visual memory. A total of 49 patients with schizophrenia and 43 healthy controls were administered a picture recognition task. Half of the pictures were black and white, and half were in color, in order to vary the depth of encoding. Processing speed was measured by three standard tasks, and premorbid IQ was measured by the National Adult Reading Test (NART). Patients were significantly impaired in picture recognition. Regression analyses revealed that NART score was a significant predictor of the recognition of both types of picture in patients. Processing speed was a significant predictor of the recognition of the colored pictures. The effect of diagnosis on the recognition of colored pictures was reduced to nonsignificance when processing speed was entered in the regression. These data suggest that premorbid IQ is involved in visual-recognition efficiency. However, the deficit observed in patients is accounted for by decreased processing speed.

Depression, avolition, and attention disorders in patients with schizophrenia: associations with verbal memory efficiency

Abstract/Results: ABSTRACT:
The authors undertook a study of the clinical correlates of verbal memory deficits in schizophrenia. The first purpose was to replicate the finding of a significant association between depression and impairment in the deep encoding memory processes. The second purpose was to test the hypothesis that certain clinical symptoms - avolition, disorders of attention - also play a role in verbal memory impairment, distinct from a global negative symptomatology score. Forty-one patients with schizophrenia underwent a memory task including forward digit span and learning lists of words with different levels of semantic organization. Regression analyses revealed that the depression score was associated with the total number of recalled words, whereas the global negative symptom score was not. Depression score was not associated with the forward digit span, a measure of superficial serial encoding processes. An analysis of individual symptoms from the Scale for the Assessment of Negative Symptoms (SANS) indicated that avolition was associated with several memory scores, suggesting a pervasive effect of this symptom. Attention disorders were associated with impaired efficiency in serial learning, but not with word recall efficiency. It is suggested that more consideration should be given to depression and motivation in the investigation of cognitive impairment in schizophrenia, as well as in cognitive remediation strategies.

Abstract/Results: ABSTRACT:
OBJECTIVE:
The aim of this study was to investigate the verbal working memory deficit and decrease of motor and cognitive speed in patients with schizophrenia, and to clarify their associations with negative and depressive symptomatology.
METHODS:
Forty patients with schizophrenia and 41 healthy control individuals were administered the backward digit span to assess the working memory capacity, along with 3 tests of processing speed.
RESULTS:
Patients demonstrated reduced backward digit span, as well as decreased motor and cognitive speed. Regression analyses indicated that the backward digit span was associated with cognitive speed. It was not associated with either negative or depressive symptoms. Decreased processing speed was unrelated to negative symptoms, but the depression score was significantly associated with the cognitive speed measure.
CONCLUSIONS:
Working memory and processing speed seem to share a cognitive component. Depression, but not negative symptoms, affects processing speed, especially by decreasing cognitive speed.

Forty-one patients with schizophrenia and 43 healthy participants underwent a memory task involving recall and recognition of lists of words, recognition of pictures, memory for temporal and spatial context of presentation of the stimuli, and remembering whether target items were presented as words or pictures.
RESULTS:
False recognition of words and pictures was associated with hallucination scores. The extra-list intrusions in free recall were associated with verbal hallucinations whereas the intra-list intrusions were associated with a global hallucination score. Errors in discriminating the temporal context of word presentation and the spatial context of picture presentation were associated with auditory hallucinations. The tendency to remember verbal labels of items as pictures of these items was associated with visual hallucinations. Several memory errors were also inversely associated with affective flattening and anhedonia.
CONCLUSIONS:
Verbal and visual hallucinations are associated with confusion between internal verbal thoughts or internal visual images and perception. In addition, auditory hallucinations are associated with failure to process or remember the context of presentation of the events. Certain negative symptoms have an opposite effect on memory errors.

Start date: 1994
History:
The BIAL Foundation was created in 1994 by Laboratórios BIAL in conjunction with the Council of Rectors of Portuguese Universities. BIAL’s Foundation mission is to foster the scientific study of Man from both the physical and spiritual perspectives.
Along the years the BIAL Foundation has developed an important relationship with the scientific community, first in Portugal and after worldwide. Today it is an institution of reference which aims to stimulate new researches that may help people, promote more health and contribute to new milestones to gain access to knowledge.
Among its activities the BIAL Foundation manages the BIAL Award, created in 1984, one of the most important awards in the Health field in Europe. The BIAL Award rewards both the basic and the clinical research distinguishing works of major impact in medical research.
The BIAL Foundation also assigns Scientific Research Scholarships for the study of neurophysiological and mental health in people, arousing the interest of researchers in the areas of Psychophysiology and Parapsychology.
To date the BIAL Foundation has supported 461 projects, more than 1000 researchers, with research groups in twenty-seven countries, resulting, until April 2013, in about 600 full papers, out of which 172 published in indexed international journals with an average impact factor of 3.6 and a substantial number of citations (1665).
Since 1996 the BIAL Foundation organizes the Symposia entitled "Behind and Beyond the Brain", a Forum that gathers well renowned neurosciences speakers and the BIAL Foundation Fellows which are spread around the world.
Classified as an institution of public utility, the BIAL Foundation includes among its patrons the Portuguese President, the Portuguese Universities Rectors' Council and the Portuguese Medical Association.

Title: BIAL Grants
Start date: 1994
History:
In 1994 the BIAL Foundation launched a programme of science research grants with the aim of encouraging the research into Man’s physical and mental processes, namely in fields still largely unexplored but which warrant further scientific analysis, as Psychophysiology and Parapsychology.
Since its launch, applications to the BIAL grants have been increasing. Up to now 461 projects have been supported, involving more than 1000 researchers from 27 countries.
The approved applications have benefited from grants in amounts comprised between €5,000 and €50, 000. The amount to be granted is fixed by the Scientific board according to the needs of each project.
The supported projects have originated, until April 2013, in about 600 full papers, 172 out of which were published in indexed international journals with an average impact factor of 3.6 and a substantial number of citations (1665).
Among the BIAL Foundation fellows is worth highlighting the presence of scientists from prestigious universities from the United States, United Kingdom, Australia, Russia, Germany, Japan, France, Canada, and many others.
The BIAL grants are promoted biannually.

Abstract/Results: ABSTRACT:
BACKGROUND:
Memory impairments in patients with schizophrenia have been associated with various cognitive and clinical factors. Hallucinations have been more specifically associated with errors stemming from source monitoring failure.
METHODS:
We conducted a broad investigation of verbal memory and visual memory as well as source memory functioning in a sample of patients with schizophrenia. Various memory measures were tallied, and we studied their associations with processing speed, working memory span, and positive, negative, and depressive symptoms.
RESULTS:
Superficial and deep memory processes were differentially associated with processing speed, working memory span, avolition, depression, and attention disorders. Auditory/verbal and visual hallucinations were differentially associated with specific types of source memory error.
CONCLUSIONS:
We integrated all the results into a revised version of a previously published model of memory functioning in schizophrenia. The model describes the factors that affect memory efficiency, as well as the cognitive underpinnings of hallucinations within the source monitoring framework.
