Respiratory dynamics and speech intelligibility in speakers with generalized dystonia.

This study investigated aspects of respiratory function, during quiet breathing and monologue, in six adult dystonic subjects and compared the findings to a control group of four neurologically intact adults. Additionally, breathing dynamics were compared with speech intelligibility. Respiratory inductive plethysmography was used to assess breathing rate, periodicity of the breathing pattern, and inspiratory lung volume. Ear oximetry was used to assess arterial blood oxygen saturation. Speech intelligibility was rated by a panel of five judges. Breathing patterns differed between groups; the dystonic subjects showed a faster breathing rate, less rhythmic breathing pattern, decreased lung volume, and apnealike periods accompanied by a decrease in arterial blood oxygen saturation. These differences were observed during quiet breathing and monologue. Decreased speech intelligibility was strongly related to differences in breathing dynamics.

Decelerative changes in heart rate are associated with performance on tasks that assess intelligence.

Changes in heart rate, chin electromyographic (EMG) activity, and respiration rate were monitored during the performance of three tasks that are commonly employed to assess intelligence in human adults. Stimuli from the digit span subtest (Expt. 1) of the Wechsler scales of intelligence, the picture completion subtest (Expt. 2), and the picture arrangement subtest (Expt. 3) were employed. A 10-s warning preceding the onset of each stimulus was also used in each of the experiments. During all three tasks there was an initial increase in heart rate during the first 3-4 s of the warning signal, followed by a decrease in heart rate during the last 5-6 s of the warning signal. Mean heart rate during the 5 s immediately preceding the presentation of stimuli to which subjects gave correct responses was significantly lower than mean heart rate during the 5 s immediately preceding the presentation of stimuli to which subjects gave incorrect responses. In addition, mean heart rate during the 5 s immediately preceding the presentation of stimuli to which subjects gave correct responses decreased significantly below the pre-warning baseline level, whereas mean heart rate during the 5 s preceding the presentation of stimuli to which subjects gave incorrect responses did not decrease below the baseline level. The differential heart rate results for correct and incorrect responses were consistent across the three tasks. No significant changes in chin EMG and respiration rate were noted during any of the tasks. Relationships among heart rate, attention to environmental information, and the role of attention in measures of intelligence are discussed.

Correlation between reaction time and intelligence in psychometrically similar groups in America and India.

The relationship between psychometrically tested reasoning ability, or general intelligence (Raven's Progressive Matrices), short-term memory (forward and backward digit span), and measures of reaction time (RT), including visual and auditory simple RT and four degrees of choice RT, was investigated in groups of unskilled workers, mostly of below average, borderline, or retarded mental ability, selected in the United States and in India. Both groups showed parallel phenomena with respect to the relative difficulty of the various RT tests, their factor structure, and their theoretically expected correlations with psychometric intelligence, although the correlations were lower (and generally nonsignificant) in the Indian group, most likely because of this group's greater restriction in range of ability. The findings, overall, are consistent with other recent studies of RT and intelligence, which indicate that our standard IQ tests reflect basic cognitive processes, particularly speed of information processing, involved in individual differences in intellectual ability, and not merely differences in specific acquired knowledge, skills, or cultural background.

General intelligence and cognitive profile in women with congenital adrenal hyperplasia (CAH).

To investigate possible effects of prenatal androgen exposure on cognitive functions, general intelligence and cognitive profile were studied in 22 women, 17-34 years old, with prenatal virilization due to congenital adrenal hyperplasia (CAH) (21-hydroxylase deficiency) and 22 healthy controls matched for region and date of birth. The tests were selected to measure abilities where gender differences repeatedly had been observed or that had earlier shown differences between CAH subjects and controls. The following cognitive functions were tested: Verbal, Visuo-Spatial, Visuo-Motor, Arithmetical, Logical Inductive abilities, and Field Dependence. Contrary to earlier reports, the mean general intelligence level of the CAH (22) group was significantly lower than the controls' and the earlier observed inferiority for calculation abilities in female CAH subjects was not supported by the results of the present study. A possible verbal disadvantage with significantly inferior results was noted for the two verbal tests for the CAH (22) group. For the 13 CAH/control pairs with equal general intelligence levels, the discrepancy between the inferior verbal vs. visual, arithmetic, and logical category scores was significantly larger for the CAH group than the controls. These results may suggest that CAH women develop a more masculine cognitive pattern under the influence of increased prenatal androgen exposure.

Social cue perception and intelligence in schizophrenia.

Previous research has shown that both acutely ill and remitted schizophrenic patients are more sensitive to the concrete, than the abstract, cues of a social situation. The purpose of this study is to determine whether this difference is attributable to a generalized performance deficit by determining whether difference in concrete and abstract cue recognition correlates with verbal intelligence. A second goal of this study is to determine whether differences in the cue perception of schizophrenic and normal control samples is also attributable to differences in verbal intelligence. Samples of inpatients (n = 23) and outpatients (n = 20) with DSM-III-R diagnosis of schizophrenia or schizoaffective disorder completed the Social Cue Recognition Test, the Vocabulary Subtest of the WAIS-R, and the Brief Psychiatric Rating Scale. Standardized residual scores representing differences in sensitivity across abstract and concrete cue recognition were not found to correlate significantly with verbal IQ in either sample. However, overall sensitivity was significantly associated with intelligence in both samples and standardized residual scores were significantly associated with thinking disturbance in the inpatients. Differences in cue perception across schizophrenic and normal control samples remained significant after adjusting cue perception scores by scores on the Vocabulary Subtest. These findings suggest that the differential deficit in cue recognition may not be attributable to generalized performance deficit.

An intelligent interactive system for delivering individualized information to patients.

This paper is a report on the first phase of a long-term, interdisciplinary project whose goal is to increase the overall effectiveness of physicians' time, and thus the quality of health care, by improving the information exchange between physicians and patients in clinical settings. We are focusing on patients with long-term and chronic conditions, initially on migraine patients, who require periodic interaction with their physicians for effective management of their condition. We are using medical informatics to focus on the information needs of patients, as well as of physicians, and to address problems of information exchange. This requires understanding patients' concerns to design an appropriate system, and using state-of-the-art artificial intelligence techniques to build an interactive explanation system. In contrast to many other knowledge-based systems, our system's design is based on empirical data on actual information needs. We used ethnographic techniques to observe explanations actually given in clinic settings, and to conduct interviews with migraine sufferers and physicians. Our system has an extensive knowledge base that contains both general medical terminology and specific knowledge about migraine, such as common trigger factors and symptoms of migraine, the common therapies, and the most common effects and side effects of those therapies. The system consists of two main components: (a) an interactive history-taking module that collects information from patients prior to each visit, builds a patient model, and summarizes the patients' status for their physicians; and (b) an intelligent explanation module that produces an interactive information sheet containing explanations in everyday language that are tailored to individual patients, and responds intelligently to follow-up questions about topics covered in the information sheet.

The relationship between measures of psychopathology, intelligence, and memory among adults seen for psychoeducational assessment.

This study assessed the relationship between symptoms of psychopathology and cognitive functioning in clients completing comprehensive psychoeducational assessments at a university-based outpatient mental health clinic. Seventy clients (36 women, 34 men, mean age=28.8) completed the Wechsler Memory Scale-Third Edition (WMS-III), Wechsler Adult Intelligence Scale-Third Edition (WAIS-III), and Minnesota Multiphasic Personality Inventory-Second Edition (MMPI-2). Partial correlations between the MMPI-2 clinical scales, WMS-III Index scores, WAIS-III Index scores, and WAIS-III IQ scores were not significant. Memory and Intelligence scores for clients with comorbid symptoms of depression and anxiety were comparable to scores for clients without comorbid symptomatology. Psychopathology factors accounted for 22% of the variance in the WAIS-III Full Scale IQ and 6.5% of the variance in the WMS-III General Memory Index. The results suggest that psychopathology as measured by the MMPI-2 may be minimally associated with intelligence and memory test performance in adults seen for psychoeducational assessment.

Emotional intelligence: the Sine Qua Non for a clinical leadership toolbox.

UNLABELLED: Over the past decade, it has become increasingly clear that although IQ and technical skills are important, emotional intelligence is the Sine Qua Non of leadership. According to Goleman [Goleman, D. (1998). What makes a leader? Harvard Business Review, 93-102] "effective leaders are alike in one crucial way: they all have a high degree of emotional intelligence...and can also be linked to strong performance." The original five dimensions of EIQ are described and applied to both supervisory and clinical scenarios. LEARNING OUTCOMES: As a result of reading this work, you will be able to: (1) define and provide an illustration of each of the five components of emotional intelligence (EIQ); (2) outline the relationship of EIQ to success in your profession and your personal life; (3) create a strategic action plan to enhance each dimension of EIQ in your daily life; (4) list at least three real-life experiences that could have resulted a favorable outcome with an improved EIQ; (5) complete a self-evaluation of your EIQ.

Intelligibility of tracheoesophageal speech in noise.

The purpose of this investigation is to determine the extent to which background noise negatively impacts the intelligibility of tracheoesophageal (TE) speech. Four male TE speakers provided speech samples that were recorded in quiet and in noise conditions. The listener/subjects occupied a sound-treated booth and were presented with two tasks. In Task 1, the subjects were required to transcribe TE speech stimuli recorded in quiet. In Task 2, the subjects were required to transcribe TE speech stimuli recorded in noise. Repeated measures 2 x 4 factorial analyses of variance were calculated for the dataset. The results of the statistical analysis revealed that the TE speech produced in quiet was significantly more intelligible to the listeners than the TE speech produced in noise for three of the four TE speakers. Furthermore, the results seem to support the hypothesis that the activation of a Lombard effect in TE speakers may detract from their overall speech intelligibility.

The neuroanatomy of general intelligence: sex matters.

We examined the relationship between structural brain variation and general intelligence using voxel-based morphometric analysis of MRI data in men and women with equivalent IQ scores. Compared to men, women show more white matter and fewer gray matter areas related to intelligence. In men IQ/gray matter correlations are strongest in frontal and parietal lobes (BA 8, 9, 39, 40), whereas the strongest correlations in women are in the frontal lobe (BA10) along with Broca's area. Men and women apparently achieve similar IQ results with different brain regions, suggesting that there is no singular underlying neuroanatomical structure to general intelligence and that different types of brain designs may manifest equivalent intellectual performance.

Two-year follow-up of intelligence after pediatric epilepsy surgery.

Research findings concerning cognitive effects of pediatric epilepsy surgery form an important basis for decisions about surgery. However, most follow-up studies have been of limited duration. In this study, a 2-year follow-up of intelligence was undertaken. Risk factors were analyzed. Included were 38 patients aged 3 to 17 years. Surgery was left in 19 patients and right in 19 patients. Types of surgery included temporal lobe resection (n = 23), extratemporal or multilobar resection (n = 8), and hemispherectomy (n = 7). The Wechsler Scales of Intelligence were administered presurgically, 6 months postsurgically, and 2 years postsurgically. No significant change in verbal or performance intelligence quotient (IQ) was demonstrated on a group level. Lateralization, type of surgery, age at surgery, sex, and presurgical IQ did not affect outcome. Across assessments, IQ scores of left-hemisphere patients were lower than those of right-hemisphere patients. Scores of patients in the hemispherectomy group were lower than those of the extratemporal or multilobar resection group, which were lower than the temporal lobe resection group. Scores improved significantly in six patients and deteriorated in seven. In conclusion, epilepsy surgery in children and adolescents does not, in general, have a significant impact on cognitive development in a 2-year perspective. In individual patients, poor seizure control and extensive surgery for Rasmussen's encephalitis were related to a deterioration of IQ.

Cognitive enhancement therapy improves emotional intelligence in early course schizophrenia: preliminary effects.

This research examined the preliminary effects of Cognitive Enhancement Therapy (CET) on social cognition in early course schizophrenia, using an objective, performance-based measure of emotional intelligence. Individuals in the early course of schizophrenia were randomly assigned to either CET (n=18) or Enriched Supportive Therapy (n=20), and assessed at baseline and after 1 year of treatment with the Mayer-Salovey-Caruso Emotional Intelligence Test. A series of analyses of covariance showed highly significant (p=.005) and large (Cohen's d=.96) effects favoring CET for improving emotional intelligence, with the most pronounced improvements occurring in patients' ability to understand and manage their own and others' emotions. These findings lend preliminary support to the previously documented benefits of CET on social cognition in schizophrenia, and suggest that such benefits can be extended to patients in the early course of the illness.

Intelligent software for laboratory automation.

The automation of laboratory techniques has greatly increased the number of experiments that can be carried out in the chemical and biological sciences. Until recently, this automation has focused primarily on improving hardware. Here we argue that future advances will concentrate on intelligent software to integrate physical experimentation and results analysis with hypothesis formulation and experiment planning. To illustrate our thesis, we describe the 'Robot Scientist' - the first physically implemented example of such a closed loop system. In the Robot Scientist, experimentation is performed by a laboratory robot, hypotheses concerning the results are generated by machine learning and experiments are allocated and selected by a combination of techniques derived from artificial intelligence research. The performance of the Robot Scientist has been evaluated by a rediscovery task based on yeast functional genomics. The Robot Scientist is proof that the integration of programmable laboratory hardware and intelligent software can be used to develop increasingly automated laboratories.

Decoding cancer with artificial intelligence: Transforming research, diagnosis, and therapy with future insights.

Cancer remains one of the leading global health burdens, with increasing complexity in genomic, imaging, and clinical datasets presenting significant challenges for effective management. Artificial intelligence (AI) has emerged as a powerful tool to address these challenges by enabling pattern recognition, knowledge integration, and data-driven decision-making. This review highlights recent advances in the application of AI across cancer research, diagnosis, and therapy. In research, AI accelerates drug discovery and repurposing, enhances genomic data interpretation, and facilitates biomarker identification through multi-omics integration. In diagnosis, AI has demonstrated high technical performance in radiology for lesion detection and image segmentation, in pathology for tumour grading and molecular prediction, and in liquid biopsy for non-invasive biomarker analysis. In therapy, AI supports precision medicine by predicting treatment responses, monitoring disease progression, and optimizing clinical trial design. Despite these advances, barriers such as data heterogeneity, algorithmic bias, interpretability, and regulatory challenges remain. Future directions, including explainable AI, federated learning, multimodal modelling, and digital twins, hold promise for translating AI-driven innovations into routine oncology practice. Significance Statement This review provides a timely synthesis of recent (2020-2025) advances in artificial intelligence across cancer research, diagnosis, and therapy, highlighting applications in drug discovery, genomics, multi-omics biomarker identification, and clinical decision-making. By integrating technological progress with translational and clinical relevance, this work serves as a valuable resource for bridging AI innovation with precision oncology practice. As a narrative review, the literature was identified through targeted PubMed, Scopus, and Google Scholar searches, combining terms for artificial intelligence, machine learning, and deep learning with cancer-related keywords, with priority given to peer-reviewed studies published between 2020 and 2025, seminal earlier works, and official regulatory or guideline documents. Within each domain, representative studies were selected to illustrate methodological diversity, clinical context, and current translational readiness rather than to provide exhaustive coverage of an extremely rapidly evolving field.

Memory and intelligence outcome following surgery for intractable temporal lobe epilepsy: relationship to seizure outcome and evaluation using a customized neuropsychological battery.

The main objectives of this prospective study were to (1) assess memory and intelligence outcome following surgery for intractable temporal lobe epilepsy, (2) correlate this with seizure outcome and side of surgery, and (3) perform (1) and (2) using an indigenously developed battery customized to the Indian population. Prior to use in our epilepsy surgery program, the test-retest and interexaminer variance reliability of this battery had been established in both normal and cognitively compromised populations. The memory scores were overall rather than material-specific. The battery was administered to right-handed adults undergoing surgery for intractable temporal lobe epilepsy without any evidence of opposite temporal lobe abnormality, both presurgery and postsurgery at a mean follow-up of 8 months. Twenty-five consecutive patients were included; 13 underwent right and 12 underwent left temporal surgery. Seizure outcome was assessed using Engel's classification. Among 13 patients who underwent right temporal surgery, although 4 patients with poor seizure outcome had insignificant changes in scores, 7 of 9 patients with good seizure outcome exhibited considerable (> 20% over preoperative) improvement in their memory and intelligence scores. Statistical analysis using Student's t test and the Mann-Whitney test revealed that the patients who underwent right temporal surgery with good seizure outcome had significant improvement in both memory (P = 0.007) and intelligence (P = 0.043) scores compared with those with poor seizure outcome. In contrast, patients who underwent left temporal surgery had no significant change in cognitive scores irrespective of seizure outcome. Cognitive improvement seems to occur in patients with good seizure outcome following nondominant temporal lobe surgery for intractable epilepsy with no evidence of pathology in the opposite temporal lobe. The same finding was not observed in patients undergoing left temporal surgery.

Dementia: the estimation of premorbid intelligence levels using the New Adult Reading Test.

The NART is a new word-reading test which was specifically designed for use with adults: the 50 words were selected in order to assess familiarity with words rather than the ability to phonetically decode unfamilar words, i.e. for each word intelligent guesswork alone would not result in a correct response. The results from a group of patients with cortical atrophy and a control group demonstrated the superiority of the NART over the best previously available word list (the Schonell GWRT) in enabling higher and more accurate levels of intelligence to be predicted. The evidence implied that the reading of the NART words was not significantly affected by the dementing processes in the patients with cortical atrophy, and therefore that the NART reading score can provide an accurate estimate of premorbid intelligence levels in these patients.

Professional judgments about the relationship between speech and intelligence in African American preschoolers.

This study investigated listener judgments of the speech of African American preschoolers. Forty-four judges (Head Start teaching staff = 18, pediatricians = 15, and speech-language pathologists = 11) were asked to watch and listen to a video tape of six children and to judge each child's speech and intelligence. Head Start teaching staff and pediatricians were both likely to perceive that speech and intelligence were related, although the two groups held differing views about the nature of that relationship. Speech-language pathologists were likely to perceive speech as being relatively independent of intelligence.

Relation between age-related decline in intelligence and cerebral white-matter hyperintensities in healthy octogenarians: a longitudinal study.

BACKGROUND: White-matter hyperintensities are commonly found on magnetic resonance imaging (MRI) of elderly people with or without dementia. Studies of the relation between severity of white-matter hyperintensities and cognitive impairment have had conflicting results. We undertook a longitudinal study of age-related decline in intellectual function and MRI at age 80 years. METHODS: From a cohort of 698 people born in 1914 and living in seven municipalities in Denmark, 68 healthy non-demented individuals had been tested with the Wechsler adult intelligence scale (WAIS) at ages 50, 60, and 70, and they agreed to further WAIS testing at age 80, and cerebral MRI at age 80-82 (mean age 82.3 years). We scored separately the numbers of periventricular and deep white-matter hyperintensities. FINDINGS: Scores for periventricular hyperintensities in this sample included all possible degrees of severity, but no participant scored more than 75% of maximum for deep white-matter hyperintensities. Neither type was related to the WAIS IQs of the 80-year assessment, but both were significantly associated with decline in performance IQ from age 50 to age 80 years (bivariate correlation coefficients 0.32, p=0.0087, and 0.28, p=0.0227, respectively). An analysis based on two WAIS subtests showed that the association between white-matter hyperintensities and cognitive impairment was significant only for cognitive decline in the decade 70-80 years. INTERPRETATION: Both periventricular and deep white-matter hyperintensities are related to decline in intelligence but, in healthy octogenarians, the cumulative effect of these features alone explains only a small part of the large differences among individuals in age-related decline in intelligence. Interpretation of the presence and severity of white-matter hyperintensities in a diagnostic context must be done cautiously.
