一日龄小鸡的记忆保持及其与脑内加压素（AVP）含量的相关研究

以一日龄小鸡为实验对象,进行一次性厌恶回避反应训练,并应用加压素的放射免疫测定法,分析比较记忆保持测验中,成绩优、劣及对照组动物与其脑内加压素含量的相关。实验结果表明,记忆保持良好的动物,脑内加压素含量明显低于对照组和记忆不良组,而记忆不良组与对照组之间则无明显差异。提示在正常生理状态下,加压素参与记忆过程的调制,并可能在这一过程中有一定的耗竭或合成减少,如适时得以补充,则对记忆的巩固和再现起易化作用。     

The Wall: On the psychology of the reunification of Germany

The fall of the Berlin Wall, which separated West Germans and East Germans for decades, led to emotional catastrophe among the reunited peoples. The authors conducted a psychological research program in Berlin to analyze individual and interpersonal processes in the reunification. They describe four categories used to pinpoint different (largely unconscious) levels of coping and defense strategies used to deal with the changes: control, splitting, symbiosis, and integration.Thomas Krauss, Dr. phil., is a family therapist and teaching supervisor.

An abbreviated history of the International Stress Management Association (ISMA)

The American Association for the Advancement of Tension Control was founded in 1973 as an interdisciplinary effort encompassing the fields of dentistry, education, medicine, physical therapy, psychology, and speech pathology. The broad purpose was to facilitate the acquisition, dissemination, and application of sound knowledge for the benefit of society throughout the world. Annual meetings were held through 1978 with dues-paying members numbering almost 1000. Name changes were first to the International Stress and Tension-Control Association and then to the International Stress Management Association (ISMA) whereupon international meetings were held in 1979, 1981, 1983, 1988, and 1992. ISMA is flourishing, with meetings planned for The Netherlands (1995) and Australia (1996).     

Quantitative CT scan studies in aphasia. I. Infarct size and CT numbers

Infarct si?e (number of 1-mm² pixels in the lesion) on CT scans of 30 aphasia patients was obtained with a semiautomated computer program. The mean number of lesion pixels present per slice containing lesion was approximately 500 for mild aphasias (transcortical motor and conduction), 700 for Wernicke's, 1000 for Broca's, 1500 for mixed, and 2000 for globals. These differences were significant for $\text{11}\text{15}$ of the group pairwise comparisons. When lesion locus was controlled for in the anterior/posterior plane, 73–100% of the aphasia patients were correctly classified as to type of aphasia by a discriminant analysis utilizing only the number of lesion pixels present on two CT slices. Different slice combinations were used for different aphasia group comparisons. There was a significant correlation between severity of aphasia and lesion size. There was a significant correlation between lesion size and the CT numbers in the lesion. This type of analysis may be useful to predict the prognosis for recovery potential in aphasics who have CT scans performed at 2 months poststroke.     

Attentional demands and recall of verbal and color information in action events

Two experiments addressed the influence of secondary task performance at encoding on recall of different features of subject-performed tasks (SPTs) involving objects (e.g., turn the wallet). In Experiment 1, memory for verbs and colors of objects was assessed, with object names serving as cues. In Experiment 2, object and color memory were assessed, with verbs serving as cues. Results from both experiments indicated a greater deterioration of memory performance under divided attention for verbal features than for colors. In addition, intention to remember did not affect performance for any feature in either experiment. The overall pattern of outcome is discussed relative to the view that encoding of verbal features of SPTs is more attention-demanding than encoding of physical task features, such as color.     

A dialogue on Zeno's paradox of Achilles and the tortoise

The five participants in this dialogue critically discuss Zeno of Elea's paradox of Achilles and the tortoise. They consider a number of solutions to and restatements of the paradox, together with their philosophical implications. Among the issues investigated include the appearance-reality distinction, Aristotle's distinction between actual and potential infinity, the concept of a continuum, Cantor's continuum hypothesis and theory of transfinite ordinals, and, as a solution to Zeno's puzzle, the distinction between infinite and indeterminate or inexhaustible divisibility.     

A resolution to the interpretive dilemmas created by the Minnesota Multiphasic Personality Inventory 2 (MMPI-2)? A reply to Ben-Porath and Graham

In my original article (Strassberg, 1991) I described (1)some of the changes introduced by the MMPI-2, (2) possible interpretive dilemmas created by these changes, and (3) strategies for dealing with these dilemmas. In their reply to my paper, Ben-Porath and Graham (preceding paper) suggest that the differences between the MMPI-2 and the MMPI (1) are to be expected, (2) are less important than I imply, and (3) when they do occur, will almost always reveal the superiority of the MMPI-2. In this reply to Ben-Porath and Graham, I explain why, despite their reassurances, I continue to contend that interpretive dilemmas can exist when using the MMPI-2, but these should not deter us from using this instrument.
