Biochemical mechanisms for the effect of alcohol on the brain]

This paper reviews and discusses basic knowledge of biochemical mechanisms of action of ethanol upon the central nervous system, the emphasis being on effects upon cerebral membrane structures and processes as well as mechanisms of chemical synaptic transmission. Results of detailed studies into material and steric changes in membranes, ion-dependent adenosine triphosphatases, variations in ion balance, effects upon cyclic nucleotides, influences on special transmitter systems, and mechanisms of formation of morphine-analogous condensation products are presented. In addition, open questions are derived and formulated in problem complexes.     

Relationship between the unconscious and motivation in establishing a therapeutic program

The need for complex psychotherapy is reified by using the combination of group psychotherapy with methods of individual and behavioral therapy as an example. The fact that certain forms of maldevelopment cannot be satisfactorily checked by dynamic group psychotherapy alone is considered to be due not only to the conditioning of, and automatism associated with, neurotic malbehavior. It is especially in the case of inordinate dread and fear of disease, which is generally referred to as nosophobia, that the patient's great difficulty in accepting the possibility of a mental origin or causation of his ailment stands in the way of making effective use of such a therapy. The authors are of the opinion that acceptance by the patient of a mental origin or causation is made difficult especially by the fact that in the case of neurotic maldevelopments the kind and degree of neurotic conflictiveness are lore or less unconscious. This fact, which has not so far received much attention, should be taken into consideration in future research into the unconscious.     

Organized youth sports and the psychological development of nine-year-old males

Two hundred thirty-two 9-year-old males were administered the Harter Self-Perception Profile before and after a season of participation in organized youth sports to assess changes in their self-perceptions of competence and self-worth. The children were participating in either soccer or baseball, and the levels of competition were either tryout or recreation. Harter's cognitive-developmental formulations suggested that soccer players and/or the recreation league players in both sports would show greater increases in self-perceptions than those involved in baseball and/or the tryout leagues. Additionally, parents and coaches rated the players on several dimensions hypothesized to be influenced by participation in youth sports. Across all groups, children's perceptions of their athletic and scholastic competence, physical appearance, and global self-worth increased from pre- to post-season. Although there were no differential changes by group, the results suggest that these activities at best promoted children's psychological development, and at worst, did not decrease their self-perceptions.

Monaural Auditory Cue Affects the Process of Choosing the Initial Swing Leg in Gait Initiation

The authors investigated the effect of an auditory cue on the choice of the initial swing leg in gait initiation. Healthy humans initiated a gait in response to a monaural or binaural auditory cue. When the auditory cue was given in the ear ipsilateral to the preferred leg side, the participants consistently initiated their gait with the preferred leg. In the session in which the side of the monaural auditory cue was altered trial by trial randomly, the probability of initiating the gait with the nonpreferred leg increased when the auditory cue was given in the ear contralateral to the preferred leg side. The probability of choosing the nonpreferred leg did not increase significantly when the auditory cue was given in the ear contralateral to the preferred leg side in the session in which the auditory cue was constantly given in the ear contralateral to the preferred leg side. The reaction time of anticipatory postural adjustment was shortened, but the probability of choosing the nonpreferred leg was not significantly increased when the gait was initiated in response to a binaural auditory cue. An auditory cue in the ear contralateral to the preferred leg side weakens the preference for choosing the preferred leg as the initial swing leg in gait initiation when the side of the auditory cue is unpredictable.
