Thirteen days: Joseph Delboeuf versus Pierre Janet on the nature of hypnotic suggestion

The problem of post‐hypnotic suggestion was introduced in 1884. Give a hypnotic subject the post‐hypnotic command to return in 13 days. Awake, the subject remembers nothing yet nonetheless fulfills the command to return. How then does the subject count 13 days without knowing it? In 1886, Pierre Janet proposed the concept of dissociation as a solution, arguing that a second consciousness kept track of time outside of the subject's main consciousness. Joseph Delboeuf, in 1885, and Hippolyte Bernheim, in 1886, proposed an alternative solution, arguing that subjects occasionally drifted into a hypnotic state in which they were reminded of the suggestion. This article traces the development of these competing solutions and describes some of Delboeuf's final reflections on the problem of simulation and the nature of hypnosis. © 2004 Wiley Periodicals, Inc.     

From the dreams of a generation to the theory of dreams: Freud's Roman dreams

In The Interpretation of Dreams, Freud's interpretation of oedipal desires does not occur at the expense of historical and personal desires, which are always there as a backdrop. In the relentless examination of his own dreams that Freud makes in order to show the mechanisms inherent in all oneiric deformation, we are also led to another, specifically historical, aspect of the issue of Jewish emancipation, which he experiences at first hand. By analysing his own dreams, Freud not only shows us the mechanisms governing dream formation, but also develops a pointed critique of his contemporary society and its prejudices.     

On the nature of nature: Experimental studies in the power of rhetoric

This paper reports two studies which investigate the effects of different definitions of the natural upon human preferences. The first study is designed to show that items are deemed more acceptable when defined as natural than when defined as non-natural. Subjects rated the acceptability of cannabis use after reading a text which either described it as a natural herb or as a drug. Acceptability ratings were significantly higher in the former condition. The second study examines how the way in which the category ‘nature’ is defined affects the acceptability of changes to the environment. Subjects watched videos which showed pictures of landscapes and then superimposed changes which consisted either of wild, non-human elements (W), human elements which fitted with the colour, texture and contours of the original (F), or human elements which were unfitting in terms of these criteria (U). It was predicted that, when we defined nature as virgin territory, W changes would be more acceptable than F or U changes. However when we defined nature as visual harmony, it was predicted that W and F changes would be equally acceptable but U changes would be less so. The results largely confirm these predictions. In discussion we argue for the importance of studying how processes of defining nature affect environment action, and for the use of experimental techniques to complement discursive investigations of such processes.     

Experimental Studies in Ocular Behavior: I. The Dodge Mirror-Recorder for Photographing Eye-Movements

Two experiments are reported concerning the effects of semantic encoding operations on the subsequent usefulness of interitem semantic relations in recall. These experiments employ the Mathews paradigm in which Ss first make judgments about the semantic relatedness of words presented in triplets and subsequently have their memory for the words tested. These experiments examine the effects of variations in interitem associative strength (Experiment 1), and task instructions and triplet order (Experiment 2). The results are discussed in terms of the general effects of the semantic judgment task on the encoding of task-relevant and task-irrelevant semantic attributes of words.     

Studies of a Child. I

The authors examined the relationship between newborn neurobehavioral profiles and the characteristics of early mother-infant interaction in Nagasaki, Japan. The authors administered the Brazelton Neonatal Behavioral Assessment Scale (NBAS; T. B. Brazelton &; J. K. Nugent, 1995) in the newborn period and the Nursing Child Assessment Teaching Scale at 1 month (NCATS; G. Sumner &; A. Spietz, 1994). They administered the Perceived Stress Scale (S. Cohen, T. Kamarck, &; R. Mermelstein, 1983) as an index of maternal stress experienced over the past month. Lower irritability, higher stability in skin coloration, and lower tremulousness in the neonatal period were correlated with higher levels of maternal nurturing behaviors at 1 month. Birth weight and 2 NBAS range-of-state items (peak of excitement, irritability) predicted 31% of the variance in NCATS caregiver subscale score. The NBAS autonomic stability items (tremulousness, startles, lability of skin color) predicted 31% of the variance in the NCATS child subscale score. Perceived stress and maternal sociodemographic variables (education, income, age, parity) were not associated with child, caregiver, and total scores on the NCATS. The results suggested that lack of autonomic stability in Japanese neonates might serve as an early indicator of infant frailty, negative behavioral cues, and decreased maternal responsiveness.
