Effect of induced elation and depression on internal-external locus of control.

This study tested the notion that depression is associated with external locus of control and elation is related to internal locus of control. Temporary mood states (depression, elation, neutral) were produced by means of Velten's auto-suggestion technique. Fifteen female undergraduates were assigned to each mood condition, and locus of control scores were obtained both before and after the mood induction procedure. Pre-post changes were as predicted: elation caused an increased sense of internality, and depression caused an increased sense of externality. Neutral mood induction did not alter locus of control.

Interviewee matching of interviewer temporal speech behaviors as related to perceived empathy, warmth, and genuineness.

The present study used an experimental analogue of the initial interview to examine the relationship of therapist durational speech characteristics to therapist empathy, warmth, genuineness and the state of the "therapeutic relationship" as rated by the interviewee. Cross-validated results revealed a modest direct relationship between interviewee speech modelling (DOU) and all process variables examined, with the exception of genuineness. Efficacy of the automated standardized interview as a research tool also was demonstrated. The results implicate the future examination of the relationship between therapist-client speech and silence measures and process variables.

A Markovian model of adult gaze behavior.

This study was designed to test a proposed Markov chain model of adult gaze behaviors. Hypotheses for an individual's gaze behavior, dyadic visual interaction, and dyadic gaze states within an independent decision model were examined. Subjects were assigned to a same- or mixed-sex dyad and instructed to converse for approximately 5 min about life at the university. Video tapes of the conversations were unobtrusively obtained and scored by an observer of gaze behaviors for 4 1/2 min in 24 pairs of subjects: eight male, eight female, and eight mixed-sex dyads. The results indicate that the occurrence of a gaze behavior is dependent on a 0.6-sec history, but infrequently prolonged Looking behaviors were found to occur slightly more often than Markovian formulations predicted. The mathematical properties of gaze behavior demonstrated in this experiment are congruent with those of dialogic time patterns, suggesting a regularity in the gross temporal organization of nonverbal communications.

Can induced moods trigger drug-related responses in opiate abuse patients?

This study investigated the ability of four hypnotically induced mood states (euphoria, depression, anxiety, and anger) to trigger craving and other drug-related conditioned responses in detoxified opiate abuse patients. Hypnotically induced depression produced significant increases in drug craving for opiates. Depression also tended to increase global self-ratings of opiate withdrawal. Other trends included increases in self-rated craving by induced anxiety and increases in withdrawal symptoms by induced anger. These results suggest that negative mood states, perhaps in the context of repeated attempts at self-medication, may become conditioned stimuli capable of triggering craving and other drug-related conditioned responses. The ability of depression to produce reliable effects in this particular patient group may reflect the high lifetime prevalence of depression diagnoses for this sample. The implications of these findings for therapeutic strategies are discussed.

Ceftazidime in the treatment of infective complications of spinal cord lesions.

The use and the abuse of the antibiotics are certainly a subject of great concern, particularly for the increasing incidence of multiresistant bacteria. Since these resistant organisms may be sensitive to cephalosporin, we have tested the effectiveness of a new cephalosporin, ceftazidime, in the treatment of resistant infection in spinal cord injured patients. A randomized study of ceftazidime versus amikacin was carried out on twenty patients. The preliminary results are presented.
