Hypnotic blindness, awareness, and attribution.

Examined whether performance on a spelling task would be influenced by visual information in the reported absence of hypnotized subjects' awareness of that information. Experiment 1 visually presented uncommon spellings of homophones to subjects before and during a suggestion for hypnotic blindness, and subsequently tested subjects' spelling of the homophones. Words presented during hypnotic blindness influenced subjects' spelling performance. Subjects' attributions of their performance did not involve awareness of the homophones. Experiment 2 used the nonexperiment methodology to examine the impact of demand characteristics and indicated that the performance attributions of subjects of Experiment 1 could not be explained in these terms. The discussion focuses on implicit perception in hypnotic blindness and on the relevance of attributions about behavioral performance on hypnotic phenomena.

Hypnotic emotions and physical sensations: a real-simulating analysis.

Real hypnotizable Ss and simulating unhypnotizable Ss were administered a suggestion for either happiness, emotional neutrality, or sadness. The emotion was assessed through subjective and behavioral measures taken once before, twice during, and once after the emotion. Findings indicated that emotionally congruent changes occurred in both self-report and performance measures. Ss' physical sensations during the emotion were assessed on a 34-item self-report scale. It was demonstrated that Ss in the happy versus sad conditions reported different physical sensations; in particular, they reported different facial sensations. The responses of real hypnotizable Ss, however, were essentially paralleled by those of simulating unhypnotizable Ss. Therefore, the possibility exists that hypnotized Ss may have been responding on the basis of social demands. The findings are discussed in terms of the effects of the emotion suggestions, and the implications of real and simulating Ss displaying similar affective responses.

Orthodontics and orthognathic surgery: adjuncts to restorative and periodontal therapy.

Orthodontic and orthognathic surgical procedures are important adjuncts to the provision of optimum restorative and periodontal care. Dentoalveolar and skeletal abnormalities of either developmental or acquired origin can be corrected primarily, thus eliminating the necessity for compromise in prosthetic design. Dental relationships that are contributory to irreversible periodontal deterioration can be normalized to facilitate stabilization of the periodontal condition and to increase the longevity of the natural dentition. Maxillofacial surgical treatment is technically complex but is more conservative than many traditionally accepted treatment procedures. It is based on the rationale of conservation of natural structures rather than their radical ablation or their sacrifice to uncontrollable progressive disease processes. Patient participation to establishment of treatment objectives and extensive patient education are essential ingredients in such treatment. Interdisciplinary communication and coordination contribute to a mutual appreciation of treatment possibilities and limitations. Thus, orthodontic and orthognathic surgical options should be considered in planning the solution to a wide variety of periodontal and restorative treatment problems.

A locking rod and tube connector.

Two methods for interlocking the segments of fixed splints are advocated: (1) solderless joints where the connector occurs between adjacent abutment teeth and (2) a locking rod and tube attachment when the connector occurs in a pontic space. The locking rod and tube attachment was described. It allows complete independence of each segment. If problems occur in any segment of the splint, only that segment must be removed to make a repair. Other splinting techniques were presented along with their advantages and disadvantages.

Measurement of distortions in fixed partial dentures resulting from degassing.

1. During the degassing phase, fixed partial dentures removed immediately when the temperature reached 1,900 degrees F (1,038 degrees C) with soldered connectors do not distort more than those with cast connectors. While not tested, heat-soaking could be expected to cause a greater amount of distortion, especially for fixed and supported partial dentures having soldered connectors. 2. Use of custom-made sagger trays giving support to long-span fixed partial dentures at the ends and within the span is desirable for both degassing and porcelain firing, regardless of whether or not the connectors are cast or soldered. 3. The accumulative amount of possible distortion resulting from soldering, degassing, and porcelain firing may be clinically significant if precautions are not affected.

The role of valence in attempted thought suppression.

Thought control was investigated in participants (N = 72) who were shown either a violent, humorous or neutral film and then administered either suppression or nonsuppression instructions. Following the presentation of a three minute segment from one film, participants monitored their thoughts for two 3-minute periods. In Period 1, participants were administered suppression or nonsuppression instructions relating to thoughts of the film. In Period 2, participants were instructed to think about anything. During both periods participants were instructed to press a response button if they had a trauma-related thought. Participants who viewed the violent film gave higher ratings of distress and lower pleasantness ratings than those who viewed the humorous and neutral films. Participants who were given suppression instructions demonstrated a delayed increase in trauma-related thoughts in the period subsequent to suppression across the valence conditions.
