The multiplicity of dreams: cognitive-affective correlates of lucid, archetypal, and nightmare dreaming

This preliminary research is the first to compare lucid, nightmare, and archetypal-mythological dreams on dimensions important in previous research on each. A first study of 100 subjects showed all three forms significantly correlated with each other and with estimates of dream recall. In a second study, 41 subjects were selected from the above on the basis of relative specialization in each dream form, with a control group equally high on dream recall. Here, the lucid and archetypal dreamers tended to separate themselves from nightmare sufferers on the basis of high imaginativeness, proclivity to waking mystical experience, spatial/analytic skills, and physical balance. It appears that the intensification of dreaming is expressed positively or negatively, depending on variations in these cognitive dimensions.     

Incomplete taste adaptation to different concentrations of salt and sugar solutions

Two concentrations each of sodium chloride and sucrose solutions were used as stimuli in a study examining taste adaptation. Twenty subjects were presented a 3-min continuous flow of each taste stimulus over the anterior dorsal tongue surface, and periodically gave magnitude estimates of its intensity. The degree of adaptation was greater for the less concentrated solutions than for the more concentrated ones, but the majority of subjects did not adapt completely to any of the stimuli. This result, which is consistent with other reports from this laboratory, is discussed in terms of individual differences among subjects and in relation to recent taste research based on completely adapted subjects.     

Pharmacological dissociation of trace and long-delay fear conditioning in young rats

In most studies comparing trace and delay conditioning, CS duration is kept constant across training conditions but the interstimulus interval (ISI), the time from CS onset to US onset, is confounded. In the infrequently used long-delay condition, however, ISI is kept constant across the trace and delay conditions but CS duration varies. A recent study reported that trace and long-delay fear conditioning have the same developmental trajectory, with both emerging later in development than standard-delay conditioning (). Past studies have shown that trace conditioning is mediated by the cholinergic system; given the parallel developmental emergence of trace and long-delay conditioning, the present study examined whether the cholinergic system also mediates long-delay conditioning. Two experiments, both involving Sprague-Dawley-derived rats and using freezing as a measure of learned fear, showed that the cholinergic system is critically involved in trace conditioning but is not involved in long-delay conditioning. Specifically, pre-training injections of the muscarinic receptor antagonist scopolamine impaired acquisition of a CS-US association in 32-day-old rats trained with a trace procedure but had no effect on rats this age trained with a long-delay procedure (Experiment 1). Similarly, pre-training injections of physostigmine, a cholinesterase inhibitor, enhanced acquisition of trace conditioning in 25-day-old rats but had no effect on long-delay conditioning in rats this age (Experiment 2). Taken together, the results indicate that despite the similarities between trace and long-delay conditioning in terms of developmental emergence and level of conditioned responding, they are mediated by different physiological systems.     

Revised norms for the Lollipop Test for children ages 42 to 65 months

Lollipop Test scores were acquired for 1,402 preschoolers in southwestern Indiana. Means and standard deviations for both boys and girls by 6-mo. intervals from the ages of 42 through 65 months showed scores increased significantly across ages, with girls scoring significantly higher than boys in all age groups. Current mean scores are similar to those published in 1988 for boys and slightly higher for girls.     

The effect of study modality on false recognition

A number of previous studies have shown that false recognition of critical items in the Deese/Roediger-McDermott paradigm is reduced when study items are presented visually rather than auditorily; however, this effect has not been uniformly demonstrated. We investigated three potential boundary conditions of the effect of study modality in false recognition. Experiments 1 and 2 showed no reduction in false recognition following visual study presentation when the yes-no recognition test was not preceded by a recall test. Experiment 3 showed that visual study presentation can reduce false recognition without a preceding recall test, if the recognition test uses remember-know instructions. The order of the recognition test items did not influence the effect of visual study presentation on false recognition in Experiment 1. In general, the data imply that distinctive processing at study can reduce false memory in recognition if the test demands draw attention to the dimension of distinctive processing.     

The Emerging Church and its discontents

The so‐called ‘Emerging Church’ constitutes a growing, if ill‐defined, Christian movement that has surfaced in North America, Europe, Australia, New Zealand and other nations of the Western world. The movement constitutes a theological and organisational critique of the conventional Christian Church, while offering a new mode of evangelism. This paper commences by briefly exploring the major attributes of the Emerging Church. It argues that although the movement can be understood as a means by which a distinct Christianity constituency has attempted to forge a juxtaposition with contemporary culture, the arrival of the movement has spurred widespread debate and produced a complex discourse indicative of the arrival of post‐modernity. The paper considers the controversy, and even acrimony, evident in the broad world of evangelicalism, in particular conservative evangelicalism, that the Emerging Church has generated.
