Diagnostic classification systems contain a core divide between neurosis and psychosis, leading to their separate study and treatment. The basis for the separation of the disorders is outlined and reassessed. It is argued that the empirical evidence does not support such a sharp distinction between neurosis and psychosis. The frequent occurrence of emotional disorder prior to and accompanying psychosis indicates that neurosis contributes to the development of the positive symptoms of psychosis. Psychological theories and experimental evidence concerning the influence of emotion on the content and form of delusions and hallucinations are therefore reviewed. It is argued that in many cases delusions are a direct representation of emotional concerns, and that emotion contributes to delusion formation and maintenance. The content of hallucinations less often directly expresses the emotional concerns of the individual, but emotion can trigger and contribute to the maintenance of hallucinatory phenomena, although how this occurs is not well understood. It is concluded that study needs to be made of the interaction between psychotic and neurotic processes in the development of delusions and hallucinations, and that neurotic and psychotic disorders may have common maintenance processes. 相似文献

Robust screening measures that perform well in different populations could help improve the accuracy of diagnosis of pediatric bipolar disorder. Changes in sampling could influence the performance of items and potentially influence total scores enough to alter the predictive utility of scores. Additionally, creating a brief version of a measure by extracting items from a longer scale might cause differential functioning due to context effects. The authors of current study examined both sampling and context effects of a brief measure of pediatric mania. Caregivers of 813 youths completed the parent-reported version of the General Behavior Inventory (PGBI) at an academic medical center sample enriched for mood disorders. Caregivers of 481 youths completed the PGBI at a community mental health center. Caregivers of 799 youths completed 10 items extracted from the PGBI at a community setting. Caregivers of 159 youths completed both versions of the PGBI and a semistructured diagnostic interview. Differential item functioning indicated that across samples some items functioned differently; however, total observed scores were similar across all levels of mania. Receiver operating characteristic analysis indicated that the 10 extracted items discriminated bipolar disorder from nonbipolar behavior as well as when the items were embedded within the full measure. Findings suggest that the extracted items perform similarly to the embedded items in the community setting. Measurement properties appear sufficiently robust across settings to support clinical applications. 相似文献

This study examined the effects of motivation to learn science, science self-beliefs, and science instructional practices
on science achievement of 13,985 15-year-old students from 431 schools across Canada. Hierarchical linear modeling (HLM) analyses,
while controlling for student- and school-level demographic characteristics, revealed the substantial predictive effects of
motivation to learn science, science self-beliefs, and science instructional practices on science achievement of adolescents.
Motivational beliefs—self-efficacy and self-concept—and enjoyment of science had substantial positive predictive effects on
science achievement. In contrast, general interest in science had a negative predictive effect on science achievement in the
context of other variables. Whereas science teaching using hands-on activities had a substantial positive predictive effect
on science achievement, science teaching using student investigations had a substantial negative predictive effect in the
context of other variables. The final HLM model indicated that only 8% of the variance in science achievement was between
schools and 92% of the variance involved students within schools. 相似文献

This article is an extension of earlier discussion in the present journal regarding feelings in literature and, more broadly,
the distinction between literary and scientific discourse. Valid though this distinction may be on some level, it is argued
herein that it owes its very existence, in part, to a problematically narrow view of what constitutes science, one that not
only eschews the life of feeling but that fails to abide by the primary obligation of the scientific endeavor—namely, to practice
fidelity to the phenomena of concern. In this respect, it might plausibly be said that much of contemporary psychological
science is not scientific enough and that, consequently, a more open and capacious conception is called for. More specifically,
it is suggested that a portion of the discipline move in the direction of what might be called poetic science, a form of science that, in its very art-fulness, can do justice to the ambiguity, complexity, and depth that characterizes
lived experience. 相似文献

An ability to flexibly shift a decision criterion can be advantageous. For example, a known change in the base rate of targets and distractors on a recognition memory test will lead optimal decision makers to shift their criterion accordingly. In the present study, 95 individuals participated in two recognition memory tests that included periodic changes in the base rate probability that the test stimulus had been presented during the study session. The results reveal a wide variability in the tendency to shift decision criterion in response to this probability information, with some appropriately shifting and others not shifting at all. However, participants were highly reliable in their tendency to shift criterion across tests. The goal of the present study was to explain what factors account for these individual differences. To accomplish this, over 50 variables were assessed for each individual (e.g., personality, cognitive style, state of mind). Using a regression model that incorporated different sets of factors, over 50?% of the variance was accounted for. The results of the analysis describe the total, direct, and mediating effects on criterion shifting from factors that include memory strength, strategy, and inherent characteristics such as a fun-seeking personality, a negative affect, and military rank. The results are discussed with respect to understanding why participants rarely chose an optimal decision-making strategy and provide greater insight into the underlying mechanisms of recognition memory. 相似文献

Three studies examined generational differences in life goals, concern for others, and civic orientation among American high school seniors (Monitoring the Future; N = 463,753, 1976-2008) and entering college students (The American Freshman; N = 8.7 million, 1966-2009). Compared to Baby Boomers (born 1946-1961) at the same age, GenX'ers (born 1962-1981) and Millennials (born after 1982) considered goals related to extrinsic values (money, image, fame) more important and those related to intrinsic values (self-acceptance, affiliation, community) less important. Concern for others (e.g., empathy for outgroups, charity donations, the importance of having a job worthwhile to society) declined slightly. Community service rose but was also increasingly required for high school graduation over the same time period. Civic orientation (e.g., interest in social problems, political participation, trust in government, taking action to help the environment and save energy) declined an average of d = -.34, with about half the decline occurring between GenX and the Millennials. Some of the largest declines appeared in taking action to help the environment. In most cases, Millennials slowed, though did not reverse, trends toward reduced community feeling begun by GenX. The results generally support the "Generation Me" view of generational differences rather than the "Generation We" or no change views. 相似文献

Unless we fixate directly on it, it is hard to see an object among other objects. This breakdown in object recognition, called crowding, severely limits peripheral vision. The effect is more severe when objects are more similar. When observers mistake the identity of a target among flanker objects, they often report a flanker. Many have taken these flanker reports as evidence of internal substitution of the target by a flanker. Here, we ask observers to identify a target letter presented in between one similar and one dissimilar flanker letter. Simple substitution takes in only one letter, which is often the target but, by unwitting mistake, is sometimes a flanker. The opposite of substitution is pooling, which takes in more than one letter. Having taken only one letter, the substitution process knows only its identity, not its similarity to the target. Thus, it must report similar and dissimilar flankers equally often. Contrary to this prediction, the similar flanker is reported much more often than the dissimilar flanker, showing that rampant flanker substitution cannot account for most flanker reports. Mixture modeling shows that simple substitution can account for, at most, about half the trials. Pooling and nonpooling (simple substitution) together include all possible models of crowding. When observers are asked to identify a crowded object, at least half of their reports are pooled, based on a combination of information from target and flankers, rather than being based on a single letter. 相似文献
