Hypnotic Responsivity from a Developmental Perspective: Insights from Young Children
Brian Vandenberg

Abstract: Evidence indicates that hypnotic responsivity in children younger than 8 years of age differs significantly from that of older children and adults. The sudden increase in responsiveness around age 8, differing patterns of item difficulty for young children, specific problems with hypnotic dream and age regression items, the lack of conceptual distinction between volition and nonvolition argue for a fundamental discontinuity between young children and adults regarding responsivity. These differences result from underlying developmental processes that characterize young childhood, including limitations in executive cognitive functioning, more overt forms of involvement, and reliance on authoritative others for direction, regulation and support. The unique features of young children's hypnotic responsivity offer the opportunity to reconsider hypnosis within a developmental context.

 

The "Big Five" and Hypnotic Suggestibility
Benita K. Nordenstrom, James R. Council, and Brian P. Meier

Abstract: A recent approach to personality measurement argues that the essential personality traits are encompassed by 5 basic factors: openness/intellect, conscientiousness, neuroticism, agreeableness, and extraversion. This study used the Big Five Inventory to test the hypothesis that 1 or more of the 5 factors underlie hypnotic suggestibility. No meaningful relationships between hypnotic suggestibility and any of the 5 factors was found.


Suggestibility and Negative Priming: Two Replication Studies
Daniel David and Richard J. Brown

Abstract: Research suggests that cognitive inhibition may be an important component of suggestibility. Two studies were conducted to address the relationship between different aspects of suggestibility and individual differences in cognitive inhibition. The first study found significant positive correlations between negative priming, hypnotic suggestibility, and creative imagination; a significant negative correlation was obtained between negative priming and interrogative suggestibility, demonstrating the discriminant validity of the study results. The second study replicated the correlation between negative priming and hypnotic suggestibility using a different suggestibility measurement procedure that assessed subjective experience, hypnotic involuntariness, and objective responses to suggestions. These studies support the notion that the ability to engage in cognitive inhibition may be an important component of hypnotic responsivity and maybe of other forms of suggestibility.


Autonomic reactivity to cognitive and emotional stress of low, medium, and high hypnotizable healthy subjects. Testing predictions from the High Risk Model of Threat Perception.
Michael M. J¿rgensen and Robert Zachariae

Abstract: This study tested hypotheses derived from Wickramasekera's High Risk Model of Threat Perception (HRMTP) by comparing autonomic and affective responses to a cognitive and an emotional stress task in high, medium, and low hypnotizables. Electrodermal activity (EDA) was used as a measure of sympathetic activity, and the high frequency (HF) spectral component of heart rate variability as a measure of parasympathetic activity. High hypnotizables exhibited greater EDA at baseline and slower EDA recovery following both tasks than did medium and lows. Medium hypnotizables responded with greater decreases in normalized HF power than did highs and lows during the emotional stress task. The results suggest diminished EDA variability in high hypnotizables and the potential for HF power as an indicator of autonomic dysregulation in low and high hypnotizables, compared to mediums. The results are discussed in relation to predictions based on the HRMTP.
