A small informal poll of local colleagues revealed that despite their interest in the subject, many had doubts about the possibility of analyzing persons aged sixty or over successfully. Their specific questions are collated and are offered as a sample of the questions in the minds of many analysts everywhere. Selected material from the ongoing analysis of a sixty-four-year-old patient is presented that bears on some of the questions raised. In addition, changes in the patient are noted. These are discussed in terms of changes in function, which are equated with structural change. The major thrust of the paper is that development continues throughout the life course, and that the criteria for analyzability remain constant. The chronological age of the adult by itself is not an indicator of eligibility or of suitability for psychoanalysis.  相似文献

An assessment of the Hasher and Zacks (1979) conceptualization of the automatic nature of the acquisition of spatial location information was made in the context of manipulations of subjects' intention to learn and mood state. The Velten (1968) mood induction procedure was used to establish depressed and nondepressed subjects. Half of each group was then presented with a matrix of geometric forms under instructions to learn the location of the forms (intentional) or to evaluate the pleasantness of the array (incidental). Subsequent tests of spatial location performance found no differences as a function of subjects' mood state, but did find a strong effect for instructional condition. The superior performance of the intentional subjects raises questions about the automatic nature of the encoding of spatial location.  相似文献

This study concerns the manner in which the traumatic events suffered by the parent in the Nazi holocaust are communicated to the second generation born after the Second World War. Additionally we investigated the effects of differences in wartime experiences on subsequent communication behaviors. Communication behaviors in families whose parents had been prisoners in concentration camps were compared with those of families who had displayed active resistance (i.e., were partisans) during the Second World War. The data indicate greater legitimacy and openness in discussing holocaust-related issues in the homes of ex-partisans than in the homes of ex-prisoners in concentration camps. Also, sons and daughters of the former group have better knowledge of the holocaust and hold more favorable attitudes than do sons and daughters in the second group. The implications of these findings are discussed.  相似文献
