Reported visual imagery for faces and facial recognition memory

Data from several studies of college students yielded moderate correlations among faces recognition scores (ratings, answers to questions), but association between visual imagery and recognition memory for faces was small to medium. Women reported more vivid and better controlled visual imagery for faces than men.     

A detailed study of sequential saccadic eye movements for normal- and poor-reading children

This paper presents the results of an in-depth study of parameters characterizing sequenced saccadic eye movements for a group of dyslexic children and a comparative normal control group with ages in the range greater than 8.0 yr. and less than 13.0 yr. No parameters were statistically different for the two groups, which supports the findings of Brown, et al. and contradicts the findings of Pavlidis. Our results indicate that sequenced saccadic eye movements are not diagnostically useful for early detection of dyslexia.     

Obesity as a variable affecting performance on the rod and frame test

Apparent similarities between S. Schachter's stimulus binding construct and H. A. Witkin's construct of psychological differentiation, specifically field dependence, have been noted in the literature. The present study examined field dependence on the rod-and-frame test among 20 obese and 42 average-weight subjects. Obese subjects were more field-dependent than were average-weight subjects. Women were slightly more field-dependent than were men. The author concluded that obese persons are more field-dependent and speculated that the constructs may be describing similar phenomena.     

Discrimination of computer-synthesized speech

The effects of learning on the discrimination of computer-synthesized speech was assessed by presenting 100 computer-produced monosyllabic words to 2 groups of 15 adult subjects. One group's errors were corrected while the other group's errors were uncorrected. A comparison of errors on the first 50 vs the second 50 presentations showed significant improvement for corrected group only. It was concluded that the discrimination of computer-synthesized monosyllables can be improved with correction of errors but is still about 14% poorer than the discrimination of human speech.     

Acoustically evoked brain stem potential in Wilson disease

By 48 patients with Wilson's disease the brainstem acoustic evoked potentials were stated. There were 35 pathological findings (73%), 13 were normal (27%). The waves, determined by the middle and upper brainstem (Pons and Mesencephalon) showed most of all pathological changes. Those patients with forms of Wilson's disease called Pseudoskelerose and Pseudoparkinson showed the most pathological findings. But one could watch these findings by about 30% of patients in preclinical stage. This method can possibly be used for early detection of disorders of brainstem functions and in the same way it can be used for control of treatment by patients in preclinical stage.     

Clinical and cisternographic differential diagnosis between presenile dementia and Hakim syndrome

The authors compared with regard clinical and the radionuclide cisternography examination 27 patients with Hakim-Syndrome and 11 with Alzheimer-Disease. In all cases, dementia was a stable symptom. Patients with Hakim-Syndrome have an early gait disturbance, ataxia and epileptic seizures. Only in case of patients with Alzheimer-Disease we found aphasia, apraxia and psychotic disorders. 24 hours after the injection radionuclide cisternography showed ventricular retention and absence of parasagital accumulation only in patients with Hakim-Syndrome. Lighter changes (mixed cisternographic pattern) were found in patients with Alzheimer-Disease as well.
