Shyness, group dependence and self-concept: attributes of the imaginary audience.

The imaginary audience of 328 early and late adolescents was studied from the viewpoint of providing educators and clinicians with insight into its attributes--those which both facilitate and hinder youths' development. Early adolescents (about 14 or 15 years of age) displayed a greater awareness of an imaginary audience which probably contributed to their observed, elevated group dependence. Unexpectedly, the shyness of adolescents highly sensitive to an imaginary audience increased with age, possibly because they are unwilling to provide themselves with the social experiences necessary for decentering. Likewise, those highly sensitive to an imaginary audience projected low self-concepts and thus imply that their audience is relatively critical; thus, they probably validate a self-fulfilling prophecy, oblivious to a possible contradictory external reality. The anticipated fact that females appeared to be less socially bold and more group dependent than males might account, in part, for females' greater responsiveness to an imaginary audience. It is suggested that educators and clinicians encourage youth to validate social hypotheses in order to promote the dissolution of the imaginary audience, especially of those who are shy and display self-deprecatory tendencies.

[Roentgenology of the median nasal fistulas (author's transl)].

The diagnosis of fistula of the nose results from the history and inspection of the patient. The radiologist main function is to rule out other diagnoses and to obtain information about location and extension of the fistula-system. This can be obtained by contrast-filling of the fistula-system in a non-infectious interval over thin-catheters or canulas. The Water's view shows whether the fistula reaches of the nasal-septum nor the cribriform-plate. Other diagnoses which have to be excluded are meningoencephalocoeles, mukocoeles and neoplastic diseases. These can be ruled out by tomography of the visceralcranium and the base of the skull.

Somatosensory evoked potentials elicited by dorsal penile and posterior tibial nerve stimulation.

SEPs were elicited by stimulation of the dorsal penile nerve (DPN) or posterior tibial nerve (PTN) under 3 conditions of stimulation: random and constant interstimulus intervals, and subject-initiated stimulation. Within these conditions, the effects of repeated stimulation were also examined. The latency of the N90 peak decreased with repeated stimulation. N90 amplitude decreased with increased foreknowledge as well as with repeated stimulation. Factors extracted by principal components analysis revealed similar effects. A difference between DPN and PTN stimulation was seen in a factor associated with the N90 peak, wherein the condition involving subject self-initiation of the stimulus reflected a significantly greater decrease in SEP amplitude when the DPN was stimulated. Morphological commonalities were observed in the SEPs elicited by DPN and PTN for a given subject.
