Complexity and measurement of hypnotic susceptibility: a comment on Coe and Sarbin's alternative interpretation.

Coe and Sarbin's claim that a single role skill dimension accounts for individual differences in hypnotizability is not supported by an empirical analysis. We suggest that current measures of hypnotic susceptibility are not only factorially complex but contain a sizable nonhypnotic variance component. Implications for the assessment of "true" hypnotic susceptibility are discussed.     

The impact of a new emotional self-management program on stress, emotions, heart rate variability, DHEA and cortisol

This study examined the effects on healthy adults of a new emotional self-management program, consisting of two key techniques, “Cut-Thru” and the “Heart Lock-In.” These techniques are designed to eliminate negative thought loops and promote sustained positive emotional states. The hypotheses were that training and practice in these techniques would yield lowered levels of stress and negative emotion and cortisol, while resulting in increased positive emotion and DHEA levels over a one-month period. In addition, we hypothesized that increased coherence in heart rate variability patterns would be observed during the practice of the techniques. Forty-five healthy adults participated in the study, fifteen of whom acted as a comparison group for the psychological measures. Salivary DHEA/DHEAS and cortisol levels were measured, autonomic nervous system function was assessed by heart rate variability analysis, and emotions were measured using a psychological questionnaire. Individuals in the experimental group were assessed before and four weeks after receiving training in the self-management techniques. The experimental group experienced significant increases in the positive affect scales of Caring and Vigor and significant decreases in the negative affect scales of Guilt, Hostility, Burnout, Anxiety and Stress Effects, while no significant changes were seen in the comparison group. There was a mean 23 percent reduction in cortisol and a 100 percent increase in DHEA/DHEAS in the experimental group. DHEA was significantly and positively related to the affective state Warmheartedness, whereas cortisol was significantly and positively related to Stress Effects. Increased coherence in heart rate variability patterns was measured in 80 percent of the experimental group during the use of the techniques. The results suggest that techniques designed to eliminate negative thought loops can have important positive effects on stress, emotions and key physiological systems. The implications are that relatively inexpensive interventions may dramatically and positively impact individuals’ health and well-being. Thus, individuals may have greater control over their minds, bodies and health than previously suspected.     

Recognition vs. recall: Storage or retrieval differences?

Differences between recognition and recall performance may be due to differences in storage processes, differences in retrieval processes, or some combination of both. An attempt was made to determine which process was critical by withholding information, at the time of study of a stimulus-response pair, about how that item was to be tested on its next presentation. It was found that differences between recognition and recall did not depend upon whether or not the subject knew, at time of study, the mode of test to be employed. These results were interpreted as support for the assertion that, in this particular task, differences in retrieval processes were sufficient to account for differences in recognition and recall. It was found that both the direction and magnitude of the recognition-recall difference depended upon the guessing correction employed.     

Visibility of an afterimage in the presence of a second afterimage

Visibility of an afterimage has been measured for a single rectangular bar on its own and in the presence of a second bar. Visibility of each bar is increased if the two bars are in the same orientation and closer than 1 deg (this effect being called “facilitation”) and is decreased if the bars are in different orientations (this effect being called “inhibition”). These interactions also depend on the relative size of the bars. If a pattern of two bars is viewed dichoptically, rivalry between the bars occurs causing a mutual decrease in visibility. The rivalry effect and the orientation-specific effects discussed above are additive in the dichoptic viewing condition. The orientation-specific effects have been likened to those found in other psychophysical studies of angle detection.

Virtue blindness and hegemony: qualitative evidence of negotiated ethical frameworks in the social language of university research administration

The study used critical discourse analysis (CDA) to elucidate normative structures of ethical behavior in university research administration which may be useful for knowledge transference to future studies of research integrity. Research administration appears to support integrity in the research environment through four very strong normative domains: (1) respect for authority structures; (2) respect for institutional boundaries; (3) professionalism; and (4) a strong sense of virtue. The strong norm structure of research administration, however, appears to be threatened by the fifth domain, (5) political power, which is inhabited by prestigious faculty with tenure, top-down authority misalignment, and the power for some institutional members to circumvent the system. The strong normative structure also appears threatened by the overall consequentiality of the regulatory environment, and shifting contexts that threaten personal virtue. In the end, the normative structure is fluid, politically acquiescent to power, and ambiguous. Although the professional core of the norm structure is strong, the strengths and weaknesses in the overall system can be connected to poorly constructed elements of the institutional environment.     

Do actions speak louder than words? Examining children’s ability to follow instructions

The ability to encode, retain, and implement instructions within working memory is central to many behaviours, including classroom activities which underpin learning. The three experiments presented here explored how action—planned, enacted, and observed—impacted 6- to 10-year-old’s ability to follow instructions. Experiment 1 (N = 81) found enacted recall was superior to verbal recall, but self-enactment at encoding had a negative effect on enacted recall and verbal recall. In contrast, observation of other-enactment (demonstration) at encoding facilitated both types of recall (Experiment 2a: N = 81). Further, reducing task demands through a reduced set of possible actions (Experiment 2b; N = 64) led to a positive effect of self-enactment at encoding for later recall (both verbal and enacted). Expecting to enact at recall may lead to the creation of an imaginal spatial-motoric plan at encoding that boosts later recall. However, children’s ability to use the additional spatial-motoric codes generated via self-enactment at encoding depends on the demands the task places on central executive resources. Demonstration at encoding appears to reduce executive demands and enable use of these additional forms of coding.
