And Control

Information-processing speed and cue reactivity were evaluated in women with bulimia nervosa and controls in response to neutral, mood, and food cues in isolation, and mood and food cues in combination. Significant differences were consistently observed between women with bulimia nervosa and control women on information-processing speed for food/body-related words, but not for words unrelated to food/body concerns. As expected, women with bulimia nervosa demonstrated slower processing of information related to food/body concerns. In addition, the presentation of mood and food cues affected speed of information processing. Especially for women with bulimia nervosa, information processing was slowest when either mood or food cues were presented in isolation. Significant cue reactivity was also observed, again especially for women with bulimia nervosa. In conclusion, both transient and more enduring subject characteristics affected information-processing speed. Moreover, the way transient factors were presented significantly affected speed of information processing. This suggests a more complex relationship between cue presentation and information processing than was anticipated.

Two reaction time tasks were compared as measures of information-processing speed. A multiple R between the WAIS—R Full, Performance, and Verbal scales and several reaction time parameters was calculated for 28 college students. Results indicate that the reaction-time task used in exploring the relationships between speed of information processing and IQ can be less complex than those used to date.

Background. Slowing of the speed of information processing has been reported in geriatric depression, but it is not clear if the impairment is present in younger patients, if motor retardation is responsible, or if antidepressant medications play a role.Method. Twenty unmedicated unipolar depressed inpatients were compared with 19 medicated depressed in-patients and 20 age-, sex- and verbal IQ-matched controls on inspection time (IT), a measure of speed of information processing that does not require a speeded motor response. We also examined the relationship between IT and current mood and length of depressive illness.Results. Unmedicated depressed patients showed slowing of information processing speed when compared to both medicated depressed patients and controls. The latter two groups were not significantly different from each other. Slowing of IT was not associated with current mood, but was negatively correlated with length of illness since first episode. No differences in IT were found between patients receiving medication with anticholinergic effects and patients receiving medication with no anticholinergic effects.Conclusions. The findings indicate that unipolar depression is associated with a slowing of speed of information processing in younger patients who have not received antidepressant medication. This does not appear to be a result of motor slowing.

Speed Of Information Processing

<b><i>Background:</i></b> Parkinson’s disease (PD) patients are known to suffer from subtle cognitive and balance deficits from the early stages although they usually manifest in advanced stages. Postural instability (PI) has been correlated with slower information processing speed. Simple reaction time (SRT) tasks can be used to measure the speed of information processing. The main objective of this study was to examine the usefulness of SRT as a valid predictor of balance in PD, thus providing a simple and complementary assessment method. <b><i>Methods:</i></b> This cross-sectional study included 52 PD patients without dementia who were evaluated for balance using the pull test (PT) maneuver and Biodex® limits of stability (LOS). In addition, a reaction time task was used to measure processing speed. Correlation and linear regression analyses were performed. <b><i>Results:</i></b> The performance of SRT tasks was correlated with the evaluation of LOS% and PT, suggesting that the SRT may be a predictor of balance performance. Longer reaction time and poorer postural stability were also associated with disease duration but not with age. <b><i>Conclusions:</i></b> Poor performance in a simple reaction task can predict altered PI and can complement staging and evaluation in PD patients.

Background: Sex differences in cognitive functioning in old age are known to exist yet are still poorly understood. Objective: This study examines to what extent differences in cardiovascular risk factors and cardiovascular disease between men and women explain sex differences in cognitive functioning. Methods: Data from 2,724 older adults from the Longitudinal Aging Study Amsterdam were used. Information processing speed and episodic memory, measured three times during six years of follow-up, served as outcomes. The mediating role of cardiovascular risk factors and cardiovascular disease was examined in single and multiple mediator models. Determinant-mediator effects were estimated using linear or logistic regression, and determinant-outcome and mediator-outcome effects were estimated using linear mixed models. Indirect effects were estimated using the product-of-coefficients estimator. Results: Women scored 1.58 points higher on information processing speed and 1.53 points higher on episodic memory. Several cardiovascular risk factors had small mediating effects. The sex difference in information processing speed was mediated by smoking, depressive symptoms, obesity, and systolic blood pressure. The sex difference in episodic memory was mediated by smoking, physical activity, and depressive symptoms. Effects of smoking, LDL cholesterol, and diabetes mellitus on information processing speed differed between men and women. Conclusion: Differences in cardiovascular risk factors between women and men partially explained why women had better cognitive functioning. A healthy cardiovascular lifestyle seems beneficial for cognition and sex-specific strategies may be important to preserve cognitive functioning at older age.

Common Situation

If rate of habituation reflects information processing speed and is a stable individual characteristic, fast habituators should habituate relatively quickly to any stimulus, and slow habituators relatively slowly. Moreover, rate of habituation should be related to the baby's tendency to explore in any common situation. To examine these inferences, 24 four-month-old infants were habituated to four stimuli (two geometric patterns and two faces) successively, in two sessions, and observed in a free-exploration situation. The number of trials required to reach criterion in the habituation situations were not correlated, but total looking times to criterion were. Also, slow habituators stayed in the exploration situation for a relatively longer time and also explored a new toy for a longer time. Methodological aspects of habituation are discussed, and an interpretation of habituation sequences in terms of cognitive style is suggested.

Background: Cognitive impairment affects half of the multiple sclerosis (MS) patient population and is an important contributor to patients’ daily activities. Most cognitive impairment studies in MS are, however, cross-sectional or/and focused on the early disease stages. Objective: We aim to assess the time course of decline of different cognitive domains. Methods: We collected neuropsychological data on 514 MS patients to construct Kaplan-Meier survival curves of the tests included in the Neuropsychological Screening Battery for MS (NSBMS) and the Symbol Digit Modalities Test (SDMT). Cox-proportional hazard models were constructed to examine the influence of MS onset type, age at onset, gender, depression and level of education on the time course, expressed as age or disease. Results: Survival curves of tests focusing on information processing speed (IPS) declined significantly faster than tests with less specific demands of IPS. Median age for pathological decline was 56.2 years (95% CI: 54.4–58.2) on the SDMT and 63.9 years (95% CI: 60–66.9) on the CLTR, a memory task. Conclusion: In conclusion, IPS is the cognitive domain not only most widely affected by MS but it is also the first cognitive deficit to emerge in MS.
