Processing of visual contour orientation information in normal and disabled reading children.

Four experiments comparing the processing of contour orientation information in normal and specific reading disabled children were conducted. The first two experiments demonstrated that the reading disabled subjects had significantly longer visual information store durations than did the control subjects. In addition differences in visual information store durations for different orientations were found between the two groups. The final two experiments investigated processing of contour orientation information in the visual cortex. Results of Experiment IV suggested that the two groups differ in their processing of information in the visual cortex as well as in VIS. Because of the importance of feature detection in letter recognition, it is suggested that the present results may be important in understanding letter recognition is disabled readers.

Suicide attempts 1973-1977--urban Hobart. A further five year follow up reporting a decline.

In urban Hobart 1968--1972 there was a steep climb in the self-poisoning rates, reaching a peak in 1972. This rise was largely attributed to an increase in self-poisonings by young males and an overall increase by females. During this period psychotropic overdoses commenced. In 1973--1977 self-poisoning and self-injury rates were calculated. Contrary to the previous five year experience rates either declined during 1973 to 1977 or fell from a previous high rate to level off at a lower rate. These changes have particularly affected both sexes under 35 years. The abuse of psychotropic substances continued to soar. A possible explanation of these changes may lie in local factors. The results are contrasted with the most recent literature.

A typology of parasuicide.

Parasuicide is not a single syndrome. Subtypes at present recognized are based largely on clinically derived stereotypes. When considering a series of patients, the clinician is unable to handle more than a few attributes at a time. This paper describes the application of three very different clustering algorithms to a material of 350 treated parasuicide patients. Mathematically, three types emerge. Clinically, two of these are interpretable and make sense. The types established are: I (n = 107) a group not characterized by any of the variables we examined; this group is a puzzle, mainly because the reasons for the parasuicidal act are not clear. II (n = 132) a depressed, alienated group with high life-endangerment. III (n = III) a group whose act was highly operant: they felt alienated and were angry with others. These groups did not differ significantly on demographic variables. The usefulness of this typology, particularly for management, after-care and prevention, has now to be assessed.
