Socially desirable responding and offence characteristics among rapists.

The relationship between socially desirable responding and offence characteristics is examined with 49 rapists. Socially desirable responding (SDR) was measured by the Balanced Inventory of Desirable Responding. Offence characteristics included: (a) perpetrator's relationship to the victim; (b) severity of victim injury; and (c) victim's age. Greater victim injury was associated with lower Impression Management (r = -.27, p < .03) and Denial scores (r = -.32, p < .01). No significant relationship occurred between offence characteristics and the self-deceptive scales of Denial of the Negative and Over Confident Rigidity. Alternative to the underreporting hypothesis, self-presentation and the acquisition of socially appropriate skills may explain the SDR/violence relationship.

Pseudomemory in hypnotized and simulating subjects.

High hypnotizable (n = 23) and low hypnotizable simulating (n = 13) subjects received pseudomemory suggestions. High hypnotizable and low hypnotizable simulating subjects were equally likely to pass the target noise suggestion during hypnosis and were also equally likely (high hypnotizables, 47.83%; low hypnotizable simulators, 64.29%) to report pseudomemories when tested for pseudomemory after instructions to awaken. As in previous research with task-motivated subjects, pseudomemory rate (high hypnotizables, 47.48%; low hypnotizable simulators, 46.15%) was not reduced by informing subjects that they could distinguish fantasy and reality in a nonhypnotic state of deep concentration. At final inquiry, after deep concentration, high hypnotizable and low hypnotizable simulating subjects' pseudomemories remained comparable (43.48% and 38.46%, respectively). Unlike previous research, high hypnotizable subjects did not report more unsuggested noises and more pseudomemories of novel sounds than did awake low hypnotizable simulating subjects. Pseudomemory reports were generally consistent with subjects' ratings of whether the hypnotist expected them to believe the sounds were real or imagined.

Pseudomemory and age regression: an exploratory study.

Hypnotizable (N = 9) and simulating subjects (N = 8) were age regressed to the previous week's hypnosis session and received a suggestion to hear a phone ring during the earlier session (no phone actually rang). Pseudomemory rates in response to open-ended questions were low in this study (0% hypnotizable and simulating subjects) and in previous research (Lynn, Weekes, & Milano, 1989; 12.5% hypnotizable; 10% simulating subjects) in which the phone-ring suggestion was not embedded in the context of age regression. In response to a forced-choice question, 22.22% of the hypnotizable and 25% of the simulating subjects indicated that the suggested phone ring was an actual event, a pseudomemory rate somewhat higher than our previous study in which none of the subjects reported pseudomemories in response to a forced-choice question. When the occurrence of the target stimulus of a pseudomemory suggestion is publicly verifiable, the pseudomemory rate is low.

Pseudomemory in hypnotized and task-motivated subjects.

Highly hypnotizable hypnotized (H; n = 16) and task-motivated (TM; n = 13) subjects received pseudomemory suggestions (see Orne, 1979). TM subjects reported being more awake and motivated than did H subjects and were more likely to pass the target noise suggestion. However, 69% of subjects in both conditions who passed the noise suggestion reported pseudomemories. Pseudomemory rate (for H subjects, 69% and for TM subjects, 46%) was not reduced by informing subjects that they could distinguish reality and fantasy in a state of deep concentration. At final inquiry, after deep concentration, pseudomemories remained stable (for H subjects, 75% and for TM subjects, 54%). As predicted, H subjects reported more unsuggested noises and more pseudomemories of novel noises than did TM subjects. Subjects who reported pseudomemories were more confident in the accuracy of their memories than were subjects who reported that the suggested noises were imagined.

Hypnosis and pseudomemories: the effects of prehypnotic expectancies.

Contrary to predictions, the pseudomemory rate of subjects who received prehypnotic information that hypnosis increased recall was indistinguishable from the pseudomemory rates of subjects who received information that hypnosis did not increase recall and of subjects who received no specific prehypnotic information. Indeed, by the last recall trial, none of the 47 subjects exhibited pseudomemory. Subjects exhibited faulty memory of events that actually occurred (i.e., pencils spilling), and were as uncertain of events that actually occurred, as they were of suggested events that did not occur during the session (telephone ringing). Subjects were generally consistent in their certainty, or lack of it, across events. Finally, subjects led to believe that hypnosis is an altered state of consciousness were less aware of external events, and had the lowest rate of recall of target suggestions compared with subjects in the comparison groups.

Literalism and hypnosis: hypnotic versus task-motivated subjects.

To extend previous literalism research with hypnotized and simulating subjects, we compared literalism rates of hypnotized, highly hypnotizable subjects (N = 12) with nonhypnotized, task-motivated subjects (N = 12) who were also highly hypnotizable. Six questions of the type used by Erickson (e.g., "Do you mind telling me your name?") constituted tests of literalism (scored if response is "Yes" or "No," either verbally or nonverbally). Whereas Erickson claimed that 97% of his "deep trance" subjects and 90% of his "medium trance" subjects exhibited literal responses, we found that 87.5% of hypnotized, high-hypnotizable subjects' responses were nonliteral. Hypnotized and task-motivated subjects did not differ in their literal responding to the individual questions or when their scores were summed across questions. No support was secured for Erickson's assertion that literalism is a cardinal feature of hypnosis.

Hypnosis, suggestion type, and subjective experience--the order-effects hypothesis revisited: a brief communication.

In a replication and extension of Field, Evans, and Orne's (1965) research, no support was found for the hypothesis that suggestion order is related to hypnotic responding. Confirming earlier findings, Ss were no more responsive to suggestions ordered from easy-to-difficult than they were to suggestions ordered from difficult-to-easy. Measures of subjective involvement in suggestions, involuntariness, and archaic involvement with the hypnotist were no more sensitive to order effects than was the measure of objective responding. Nor were order effects more apparent with Ss who received direct versus indirect suggestions. Direct suggestions facilitated suggestion-related involuntariness and response to the hypnotic amnesia item after cancellation, whereas indirect suggestions enhanced fears of negative appraisal by the hypnotist. Finally, female Ss were more involved in suggestions than were the males, particularly in response to more difficult test items.

Literalism as a marker of hypnotic "trance": disconfirming evidence.

The responses given by highly hypnotizable, hypnotic subjects and those of unhypnotizable subjects who simulated hypnosis to questions of the type, "Do you mind telling me your name?" and "Do you mind standing up?" were contrasted. The purpose was to examine Erickson's (1980) assertion that literalism (answering "yes" or "no" verbally or nonverbally without any cognitive elaboration) is a marker of hypnotic "trance." Simulators exhibited a greater rate of literalism than hypnotic "virtuosos" (i.e., extreme scorers on both group and individual hypnotizability measures). Hypnotized subjects and nonhypnotized subjects approached in the campus library responded comparably. Because less than a third of hypnotic virtuosos responded literally, our results strongly refuted Erickson's assertion that literalism is a cognitive feature of hypnosis.

Reality versus suggestion: pseudomemory in hypnotizable and simulating subjects.

Assigned hypnotizable (N = 56) and simulating Ss (N = 44) to 1 of 4 conditions: heard a phone ring and conversation, received a suggestion to hear a phone ring and conversation, received a suggestion and heard a phone ring and conversation, or neither heard a phone nor received a suggestion. Hypnotizable Ss successfully discriminated objective events from suggested sources of input. When Ss received a suggestion to hear a phone ring, only 11.5% indicated it actually rang in their open-ended reports; in response to a forced-choice question, none did so. In spontaneous reports, none of the hypnotizable Ss who heard a phone ring indicated it was suggested; only one did so in response to a forced-choice item (vs. 2 simulators). In the no-phone/no-suggestion condition, more simulators than hypnotizable Ss indicated that a phone rang or was suggested.

Age-related responses to influenza vaccination in the Newcastle region during 1983 and 1984.

A study was carried out in Newcastle to assess responses to influenza vaccines in elderly nursing home patients and in younger adults during 1983 and 1984. The decision to vaccinate the elderly subjects was made by their general practitioners. A concurrent randomized placebo-controlled trial of the same vaccine was performed in young adult volunteers. Elderly subjects generally possessed higher levels of pre-existing antibody to the influenzal haemagglutinins that were present in the vaccines than did younger subjects. The highest levels were observed in the 52-63 years' age group. Younger subjects showed significantly greater responses to vaccines compared with elderly subjects (P less than 0.05). Peak responses were noted in the 16-24 years' age group. Of a total of 326 elderly subjects (70% of whom had been vaccinated), six participants, two of whom had been vaccinated, contracted laboratory-proven influenza during 1983. Only one unvaccinated subject of a total of 365 subjects (50% of whom had been vaccinated) contracted influenza during 1984. In both years illness was produced by strain A/Philippines/2/82.

Hypnotic interview and age regression procedures in the elicitation of multiple personality symptoms: a simulation study.

Patients diagnosed as suffering from multiple personality (i.e., multiples) behave as though they possess two or more distinct personal identities. When behaving as one identity, these patients often display signs of amnesia for events that occurred while they were behaving as a different identity (Sutcliffe and Jones 1962; Taylor and Martin 1944). In most theoretical accounts multiples are conceptualized as the passive victims of unconscious psychological processes that are beyond their sphere of control. For instance, patients' secondary identities are typically described as "dissociated" mental entities, as "taking over" behavioral control, as behaving independently of (and often in opposition to) patients' wishes and intentions, and so on (Allison and Schwarz 1980; Gruenewald 1984; Prince 1930; Watkins and Johnson 1982). Our paper criticizes this traditional account and suggests instead that multiple personality may be more usefully conceptualized as a social role enactment. Along these lines we present a study using college student role players as subjects to test the hypothesis that the kinds of clinical interview procedures employed routinely to diagnose multiple personality may instead encourage and legitimate enactments of this syndrome.
