Blood pressure responses to hypnotic and nonhypnotic suggestions in normotensive subjects

Forty normotensive subjects participated on a voluntary basis in a study designed to compare the effect of suggestions on blood pressure (BP). Two experimental groups received suggestions presumed to be specific in lowering or raising BP after simple relaxation (relaxation group) or hypnotic induction (hypnotic group). A control group was used to record the BP changes over time. The time variable was significant for both systolic (SBP) and diastolic blood pressure (DBP). Induction procedures (hypnosis or relaxation) resulted in significant decreases in DBP in both experimental groups. In the control group there was a significant decrease in SBP. A specific suggestion to increase the BP resulted only in DBP increase in the hypnotic group. This group also gave an increase of both SBP and DBP over the entire experiment, whereas the relaxation group resulted in a significant decrease in SBP. There was no significant group variable, indicating no differences between the groups. Further research is needed to enable firm conclusions of the effect of suggestions on BP.     

Reconsidering formative measurement

The relationship between observable responses and the latent constructs they are purported to measure has received considerable attention recently, with particular focus on what has become known as formative measurement. This alternative to reflective measurement in the area of theory-testing research is examined in the context of the potential for interpretational confounding and a construct's ability to function as a point variable within a larger model. Although these issues have been addressed in the traditional reflective measurement context, the authors suggest that they are particularly relevant in evaluating formative measurement models. On the basis of this analysis, the authors conclude that formative measurement is not an equally attractive alternative to reflective measurement and that whenever possible, in developing new measures or choosing among alternative existing measures, researchers should opt for reflective measurement. In addition, the authors provide guidelines for researchers dealing with existing formative measures.     

DIMENSION ANALYSIS OF THE PERCEPTION OF INSTRUMENTAL TIMBRE

W edin L. & G oude G. Dimension analysis of the perception of instrumental timbre. Scand. J. Psychol ., 1972, 1 3 , 228–240.—The dimensionality of the perception of instrumental timbre for single tones was investigated through multidimensional scaling according to Ekman's vector model of similarity. Three factors were extracted and they were identified with certain characteristics of the spectrum envelopes. It was found that initial transients were important for the identifiability of instrumental tones but their presence or absence did not influence the dimensional structure. The "perceptual structure" was found to be different from the "cognitive structure" (= knowledge about the classification of the instruments), and the results are general for both trained and naive listeners.     

APPROACH AND WITHDRAWAL IN YOUNG OF TILAPIA MOSSAMBICA (CICHLIDAE, PISCES) AS A FUNCTION OF AGE AND SOCIAL EXPERIENCE

G oude G., E dlund B., E ngqvist -E dlund U. & A nderson M. Approach and withdrawal in young of Tilapia mossambica (Cichlidae, Pisces) as a function of age and Social experience. Scand. J. Psychol ., 1972, 13 , 89–97.—In an experiment with eight groups of young of Tilapia mossambica , approach and withdrawal behavior was registered during brief (5 min) periods of stimulation with a moving dummy; the experiment lasted twelwe days (towards the end and immediately after the sensitive period). Four of the groups comprised young which had been isolated from each other until the first stimulation period; in the other four groups the young had been kept together in the experimental tanks. The age of the young when first stimulated was varied experimentally. Changes in approach and withdrawal behavior over time were studied along with e.g. changes in group strength. Age at first stimulation was found to be of some consequence but no clear differences were obtained between groups with different environmental experiences.     

Stroop effects for masked threat words: Pre‐attentive bias or selective awareness?

The single‐trial emotional Stroop effect for masked threat words, and its association with anxiety, anger, and depression was studied in a group of men (n = 24) and women (n = 24) while controlling for possible differential thresholds for threat words versus neutral words. Stroop interference for masked threat words was found to correlate with trait anxiety, and the effect could not be explained by any differences in thresholds due to valence, neither at a subjective (conscious identification task) nor at an objective (lexical decision task) level of awareness. Jacoby's exclusion task was explored as an alternative measure of conscious awareness, and the results corroborated the conclusion that the Stroop effect for masked threat words was the result of preattentive processes. Unexpectedly, however, the correlation between Stroop interference for masked threat words and trait anxiety was found only among the men.     

Can this be evil? Evilness seen as intention or drive

This article was originally read as an introductory plenary paper at the German-Nordic Clinical Conference, September 2015 in Berlin. The heading of the conference was ‘On Cruelty and Destructiveness’. The paper takes as its starting point the composite figure of Dr Jekyll and Mr Hyde. It discusses the meaning of intentionality, or the lack of a conscious intention of being evil, in comparison to evil deeds caused by uninhibited drive satisfaction. Evilness is put into a social and a psycho-developmental context. Examples of contemporary atrocities are discussed, leading up to a formulation of a multi-factorial explanatory model of evil, taken from Michael Stones book ‘The Anatomy of Evil’.
