ABSTRACT 'Ulysses contracts' are an instrument through which a psychiatric patient may prearrange involuntary commitments to be put into effect if the patient satisfies certain diagnostic criteria in the future. Proposals for Ulysses contracts typically impose numerous safeguards. This paper argues against the intuitively plausible safeguard which permits only presently remitted patients to contract. Instead of requiring a patient's remission, it is argued that the appropriate safeguard is the patient's ability, whether remitted or not, to offer good reasons for wishing to contract. In short, what matters is not an executive's character, but an executive's reasons, and a bad executive may have good reasons. Attempts to deny the accessibility of good reasons in unremitted patients are rejected on the ground that psychiatric diagnosis requires psychiatrists to be able to distinguish between good and bad reasons in both remitted and unremitted patients. If psychiatrists cannot do that, psychiatric diagnosis is impossible.  相似文献

Summary How much does the recall of affectively positive, negative, and neutral words that differ in their emotional impact depend on the conceptual processing of these words? To answer this question one group of subjects were requested to rate the pronounceability of these words (formal orienting task), but were later tested for recall. Subsequently, they were asked to judge the intensity of the emotions aroused by the words. Another group of subjects received the latter, self-related task prior to the first exposure to the words. In both conditions the highly affect-arousing words were better recalled than the less emotional words. The affectively positive words were particularly well recalled, but only by those subjects involved in the formal orienting task. It is concluded that words are evaluated for their emotional content at an early stage of information processing as defined by Craik and Lockhart (1972).Extended version of an earlier paper delivered at the 34.

Summary Previous research has demonstrated that the emotional properties of words and their imaginability affect their recallability and that verbal material is recalled better when it is related to subjects' current concerns. This study investigates the extent to which this effect of emotion on recall varies as a function of cognitively controllable inference processes and examines the relation of the effects of emotion to those of imaginability and concern-relatedness. Forty different words were presented visually under one of six orienting conditions that varied according to what the subject was asked to rate: their length, pronounceability, concreteness, defineability, the strength of emotion elicited by the word, and the relation of the word to personal concerns. Subjects were then asked to write as many words as they could recall. Words that aroused stronger emotion and were easier to represent in imagery were recalled better than emotionally less arousing and imaginally less evocative words, regardless of the nature of the orienting task. The evidence suggests that the emotional properties of words are evaluated automatically in an early processing stage, without requiring subjects to reflect on word content. Emotional arousal appears to mediate the effects of current concerns on recall. It is correlated with but appears to function independently of word imaginability.  相似文献

Major companies in the mainframe statistical software business have started producing powerful versions of their programs for microcomputers. Five of the leading microcomputer statistical packages are reviewed. A statistical software vendor directory is provided. These statistical packages can be used by properly trained personnel to make more reliable business decisions.  相似文献

This article describes some essential computer skills needed by psychology students seeking careers in business. It is suggested that students become familiar with computer software packages in the following areas: statistical analyses, wordprocessing, spreadsheets, data base managers, and graphics. Discussion is provided.Paper presented at the 57th Annual Convention of the Midwestern Psychological Association, Chicago, Illinois, May 1–3, 1985.  相似文献

A comparison of the WISC-R and the Woodcock-Johnson Psycho-Educational Educational Battery (W-J) was made for children with regular and learning-disabled (LD) class placement. The W-J and Wechsler Intelligence Scale for Children-Revised (WISC-R) evidence low to moderate correlations and significant mean differences, indicating that the two tests are measuring somewhat different abilities to somewhat differing degrees. W-J—WISC-R correlations for the regular students exceed those of the LD students in the greater majority of the cases. Rank ordering of the WISC-R subtests and the W-J clusters indicate, as might be expected, that the LD students fare the worst in the WISC-R academic subtests (Arithmetic, Information and Vocabulary) and in the W-J academic clusters. More research needs to be conducted with the W-J before it should be adopted for use in the placement of exceptional children.  相似文献

Subjects were presented with a sequence of picture-word items. The pictures were line drawings of common objects, and the words were the names of the objects. Half of the items were followed quickly by the next item, and the other half by a 15-sec “rehearsal interval.” The subjects were told to use these intervals to rehearse the item just presented, either by saying the word over and over to themselves or by maintaining the picture before the mind’s eye. There followed a test in which each item from the study list was cued with a fragment of either the picture or the name. Consistent with previous findings, identification was more probable for fragments of items that had been followed by a rehearsal interval. In addition, this advantage was found to be greater when the type of cue matched the mode of rehearsal that the subject had been instructed to adopt; there was in fact little, if any, advantage of rehearsal when cue and mode of rehearsal mismatched. This pattern of results suggests functionally distinct pictorial and verbal modes of rehearsal that serve not only to maintain information in conscious mind but also to build up memory proper.  相似文献
