Closeness, warmth, perhaps touching, and some understanding are characteristic of interpersonal relationships. However, there are dangers of intrusion and insensitivity when persons invite pastors to become intimate. Superficial and false intimacy may substitute for closeness. Pastoral care should transcend the primitive holy man role, which is cold because the holy is desexualized. Intimacy is a closeness between persons in areas we tend to guard as personal.He is the author ofThe Power to Bless andRaise the Dead. 相似文献

Visual masking between nonoverlapping gratings depends on the similarity of their spatial frequencies. In a metacontrast experiment, bar gratings of 6 and 12 cycles/deg were masked by flanking gratings of various spatial frequencies. For three observers, masking was greatest when the masking frequency was approximately equal to the masked frequency. The results are interpreted in terms of a theory of reciprocal inhibition among frequency-specific neural units. 相似文献

The inconsistency of previous results concerning the effects of alcohol on reaction time (RT) may be related to possible tradeoffs between speed and accuracy. In the present experiment, complete speed-accuracy tradeoff functions were generated for each of five doses of alcohol (0-1.33 ml/kg) in a choice RT task. Such functions permit RT differences resulting from changes in performance efficiency to be distinguished from those due to changes in subjects’ speed accuracy criteria. Increasing doses of alcohol produced a progressive decrease in the slope parameter of linear equations fit to the speed-accuracy data, but did not significantly alter the intercept of the functions with the RT axis. Thus, alcohol reduced performance efficiency by decreasing the rate of growth of accuracy per unit time. A change in speed-accuracy criterion was combined with the decrease in efficiency at the highest alcohol dose. 相似文献

Three food-deprived Long-Evans rats were exposed to a non-discriminated shock avoidance procedure. Superimposed upon this operant avoidance baseline were periodic presentations of a conditioned stimulus that was paired with food, the unconditioned stimulus. These pairings resulted in increases in the rate of shock over that recorded when the conditioned stimulus was not present. A traditional suppression ratio failed to reveal any differential effect of the conditioned stimulus on the overall rate of avoidance responding, although all subjects showed a consistent pattern of pausing and postshock response bursts during presentations of the conditioned stimulus. When food was withheld during a final extinction phase, the conditioned stimulus ceased to occasion increases in shock rates and disruptive postshock response bursts were eliminated. An analysis of conditioned suppression procedures is proposed that stresses not only operant-Pavlovian or appetitive-aversive incompatibility, but also the manner in which the baseline schedule of reinforcement affects operant behavior changes that are elicited by the superimposed Pavlovian procedure. 相似文献

Single letters and redundant CVCs and CCCs were presented at threshold durations and followed by a pattern mask. Performance on three-letter stimuli was greater than on single letters. The increased performance was consistent with a state model of perceptual independence. Conditional redundancy increased the frequency with which all three letters were accurately reported as compared to correlational redundancy. Meaning and pronounceability had little effect on performance. 相似文献

Four experiments examined the hypothesis that the Valins (1966) false physiological feedback effect with attractiveness ratings of slides is due to experimenter demand. Experiments 1 and 2 showed significant feedback effects with 5-sec feedback periods, previously reported by Barefoot and Straub (1971) to be too brief a time to search the slides for a cause of the apparent physiological arousal. Experiments 3 and 4 had 17 variations of instructions (emotional, nonemotional), stimuli (slides of people, scenic tourist slides), and type of feedback information (heart rate, eyeblink, or none). The typical false feedback effect was found under many conditions that did not seem to meet the presumptive attributional requirements for the effect. In Experiment 4, only subjects who said they were supposed to rate feedback slides higher showed the effect, regardless of instructions, stimuli, or type of feedback. The overall results are interpreted in terms of experimenter demand and stimulus salience effects. 相似文献

Two kinds of measures of multivariate association, based on Wilks' and the Bartlett-Nanda-Pillai trace criterionV, respectively, are compared in terms of properties of the univariateR
2 which they generalize. A unified set of derivations of the properties is provided which are self-contained and not restricted to decompositions in canonical variates. One conclusion is that asymmetric index based on allows generalization of the multiplicative decomposition ofR
2 in terms of squared partial correlations, but not the additive decomposition in terms of squared semipartial correlations, while the reverse is true for anasymmetric index based onV.We are indebted to Jos M. F. ten Berge for some fruitful discussions. 相似文献

Groups of 30 ADD-H boys and 90 normal boys were divided into 30 mixed dyads composed of a normal and an ADD-H boy, and 30 normal dyads composed of 2 normal boys. Dyads were videotaped interacting in 15-minute free-play, 15-minute cooperative task, and 15-minute simulated classroom settings. Mixed dyads engaged in more controlling interaction than normal dyads in both free-play and simulated classroom settings. In the simulated classroom, mixed dyads completed fewer math problems and were less compliant with the commands of peers. ADD-H children spent less simulated classroom time on task and scored lower on drawing tasks than normal peers. Older dyads proved less controlling, more compliant with peer commands, more inclined to play and work independently, less active, and more likely to remain on task during the cooperative task and simulated classroom settings. Results suggest that the ADD-H child prompts a more controlling, less cooperative pattern of responses from normal peers. 相似文献
