Myths and misconceptions about hypnosis and suggestion: Separating fact and fiction

We present 21 prominent myths and misconceptions about hypnosis in order to promulgate accurate information and to highlight questions for future research. We argue that these myths and misconceptions have (a) fostered a skewed and stereotyped view of hypnosis among the lay public, (b) discouraged participant involvement in potentially helpful hypnotic interventions, and (c) impeded the exploration and application of hypnosis in scientific and practitioner communities. Myths reviewed span the view that hypnosis produces a trance or special state of consciousness and allied myths on topics related to hypnotic interventions; hypnotic responsiveness and the modification of hypnotic suggestibility; inducing hypnosis; and hypnosis and memory, awareness, and the experience of nonvolition. By demarcating myth from mystery and fact from fiction, and by highlighting what is known as well as what remains to be discovered, the science and practice of hypnosis can be advanced and grounded on a firmer empirical footing.     

Verbal interactions of aggressively and nonaggressively predisposed males in a drinking situation

The effects of progressive intoxication were studied in male social drinkers classified from prior histories as either aggressively (A) or nonaggressively (NA) predisposed while intoxicated. Two groups of two A and two NA subjects engaged in videotaped group discussions that were analyzed by Bales interaction process analysis (IPA). At comparable levels of ad libitum alcohol intake in a natural drinking environment, significantly more verbal activity was displayed by the A subjects than by the NA subjects (P <.001), including IPA category D (P <.025). The A subjects tended to address the group as a whole rather than individual members (P <.001) and NA subjects rather than other A subjects (P <.01). Free testosterone levels assessed from saliva were higher among A subjects than among NA subjects (P <.05) with no significant changes related to time and progressive intoxication. The results suggest that the tendency to behave aggressively while intoxicated may be a fairly stable individual trait, possibly related to androgen levels and active or coercive modes of social communication.     

Reactivity of Tic Observation Procedures to Situation and Setting

Tic frequency was assessed and compared across home and clinic as well as three experimentally-manipulated situations in order to assess the phenomenon of tic reactivity. Forty-three youngsters with chronic tic disorder recruited from two geographically-distinct sites were videotaped over three weekly laboratory visits under each of the following conditions: (1) alone/camera present, (2) other present/camera present, and (3) alone/camera hidden. Contrary to expectation, more tics were observed during overt as compared to covert observation, while the presence of another person had no overall impact on tic expression. Mean tic counts obtained from clinic observation did not significantly differ from those obtained at home collected either one day before or after. Tic frequency counts were remarkably stable over the three weekly assessments both at home and clinic. Study findings are consistent with past observations that tic expression can be influenced by environmental factors and suggest the stability of tic frequency may exhibit greater temporal and setting stability than previously thought. The clinical and research implications of these results are discussed.     

Effects of mand-tact versus tact-only training on the acquisition of tacts

We sought to replicate and extend Carroll and Hesse's (1987) study of the acquisition of tacts by including participants with and without developmental disabilities. As in Carroll and Hesse, the present results showed that mand-tact training, rather than tact-only training, led to more rapid acquisition of tacts. Tacting on follow-up tests did not differ. In addition, our results show that mand-tact training established both verbal operants involved about as rapidly as tact-only training established only one verbal operant.

Reducing child witnesses' false reports of misinformation from parents.

This study explored whether a source-monitoring training (SMT) procedure, in which children distinguished between events they recently witnessed versus events they only heard described, would help 3- to 8-year-olds to report only experienced events during a target interview. Children (N = 132) who witnessed science demonstrations and subsequently heard their parents describe nonexperienced events received SMT before or after a forensic-style interview. SMT reduced the number of false reports that 7- and 8-year-old children reported in response to direct questions but had no impact on the performance of younger children. Combined with earlier results, these data suggest a transition between 3 and 8 years of age in the strategic use of source-monitoring information to support verbal reports, such that only 7- and 8-year-olds generalize training to a difficult memory task that does not include mention of specific alternative sources.     

Children's Testimony: A Review of Research on Memory for Past Experiences

This review of children's testimony focuses on research related to memory for past experiences. The aspects of the memory system that are involved in testimony are discussed and the development of autobiographical memory is examined. Relevant research findings are summarized in the context of an information-processing model of memory and the implications of this work for clinical practice are outlined. We conclude that (1) under certain conditions, even very young children can remember and report past experiences with some accuracy over very long periods of time; (2) substantial and significant developmental differences have been demonstrated in children's abilities to provide eyewitness testimony; (3) children can be influenced in a variety of ways to provide complete and elaborated reports of events that never occurred; and (4) even experts cannot always tell the difference between true and false reports.     

FUNCTIONAL ANALYSIS AND TREATMENT OF INAPPROPRIATE VERBAL BEHAVIOR

The present study examined the possible function of inappropriate verbal behavior of an adult man who had been diagnosed with both mental retardation and psychosis. Results of a functional analysis indicated that inappropriate verbal utterances were maintained by attention. An intervention consisting of the differential reinforcement of appropriate verbal behavior effectively reduced the inappropriate behavior.     

高述情障碍者的情绪图式特征

采用混合实验设计,以情绪词和情绪图片为实验材料,选取不同述情障碍得分的大学生为被试,通过三个实验考察了高述情障碍者的情绪图式特征。研究结果发现：（1）高述情障碍组被试对情绪词的效价判断反应时显著长于低述情障碍组,述情障碍各维度得分均与情绪词的效价判断反应时呈显著正相关;（2）高述情障碍组被试对情绪图片的效价判断反应时与低述情障碍组相比差异不显著;（3）高述情障碍组被试情绪图式联结所需反应时显著长于低述情障碍组,情感描述困难与情绪图式联结所需反应时之间相关显著。研究结论如下：高述情障碍者存在情绪语言图式和参考性链接上的缺陷,而在情绪意象上并不存在积极/消极区分能力方面的缺陷     

Projective identification: A theoretical investigation of the concept starting from ’Notes on some schizoid mechanisms’1

This paper submits passages from four papers‐‘Notes on some schizoid mechanisms’ (Klein); ‘On identification’ (Klein); ‘Analysis of a schizophrenic state with depersonalization’ (Rosenfeld); and ‘Remarks on the relation of male homosexuality to paranoia, paranoid anxiety and narcissism’ (Rosenfeld)‐to a critical reading, enabling the theoretical premises which have produced the current, differing views on projective identification to be traced. These views revolve both around the role assigned to identification in the process and around the meaning of the expression‘to identify oneself with’ which in ‘On identification’ goes from ‘to feel similar to, or identical to the other’ to ‘to take another person as a model’. This legitimizes the inclusion of very different phenomena into the concept of projective identification. The author describes some uses of the term ‘projective identification’ and proposes the hypothesis that the process constitutes a way for managing otherness and the separateness of the object (be it external or internal, real or imaginary) that can compromise its reality to a greater or lesser degree. Covering a large set of phenomena, the author poses the question of whether it is useful to retain the term ‘projective identification’. She proposes an answer in the last part of the paper.     

Naming and categorization in young children: v. manual sign training

Following pre-training with everyday objects, 8 children aged from 2 to 4 years learned to produce one manual sign (fists placed one above the other, in front of body) to one stimulus and an alternative manual sign (shoulders touched with ipsilateral hands) to the other stimulus, with each of three pairs of different arbitrary wooden shapes (Set 1). The six stimuli then were presented in category match-to-sample tests, which all subjects passed. Three of the children were next trained to produce the manual signs (denoted as fist/shoulder) for an additional six arbitrary stimuli, Set 2. All 3 children went on to pass category match-to-sample tests for Set 2, and for Set 1 and Set 2 combined. In the final experimental phase, 2 of the children were trained, for one of the six stimulus pairs, to produce the vocal tact "zag" to one stimulus and "vek" to the other. Both children showed category transfer of these vocalizations in test trials with each of the remaining five stimulus pairs, and all the stimuli combined in a 12-stimulus array. In line with Horne and Lowe's (1996) naming account, manual sign naming was found to be as effective as vocal naming in establishing arbitrary stimulus categorization, measured in terms of category sorting and transfer of function. The findings also have implications for the training of verbal repertoires in people with learning disabilities.
