A longitudinal investigation of physician's assistants' perceptions as members of a health care team: a preliminary study. (17/18)

The perceptions of a cohort of 124 Physician's Assistants (PA) were assessed by responses to questionnaires employing the semantic differential. Profiles at beginning and end of training and as a health worker on the job suggest that other members of the health team are viewed favorably and that PAs' self perceptions may change over time to become more like their perception of nurses and less like their perception of physicians.  (+info)

An experimental investigation of preorgasmic reconditioning and postorgasmic deconditioning. (18/18)

The effects of pre- and postorgasmic presentation of moderately erotic cues were assessed in an analogue study. Eight heterosexual male volunteers (18 to 23 years) participated in three assessment (baseline, termination-of-treatment, and two- to three-month followup) and eight masturbatory conditioning sessions. Three slides of nude females of initially equal erotic value were paired respectively with the plateau, refractory, and resolution phases of the subjects' sexual cycles. Over treatment, stimuli paired with the plateau phase increased significantly in penile tumescence indices of eroticism; conversely, stimuli paired with the refractory phase decreased significantly. The conditioned effects on tumescence were largely extinguished at followup. While treatment did not alter short-term subjective indices of eroticism, stimuli presented during the refractory phase were rated significantly less erotic than the other stimuli at followup. The findings suggest that the "pairing" model of orgasmic conditioning is insufficient to account for previously reported clinical findings. A broader conceptualization of the mechanisms of orgasmic conditioning, and implications for treatment are discussed.  (+info)
