Knowing that you don't know: Metamemory and discourse processing.

In 6 experiments, the authors used a speeded question-answering task and a recognition task to examine how people know what they don't know. Extending work by S. Glucksberg and M. McCloskey (1981) to examine metamemory judgments about narratives, the authors asked participants to respond to 2 types of "don't know" questions. In certain conditions, readers were faster to respond "don't know" to implicit "don't know" questions (i.e., no information regarding the answers was provided) than to explicit "don't know" questions (i.e., narratives explicitly stated that something was unknown). The speed of responding to the implicit "don't know" questions was related to the familiarity of the question, which is consistent with claims that fast metacognitive judgments are based on a preliminary evaluation of the familiarity of a cue. This is a first step in integrating theories of metacognition and discourse processing. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Visual memory: what do you know about what you saw?

Recent studies of visual perception are bringing us closer to an understanding of what we remember - and what we forget - when we recall a scene.     

Noninvasive pacing: what you should know

Noninvasive pacing is a valuable therapy in emergency cardiac care. The more experience clinicians have with the noninvasive pacing procedure, the greater their confidence and the easier the job becomes. Effective troubleshooting during pacing becomes less problematic with increased experience with the therapy. Noninvasive pacing allows rapid initiation of emergency pacing and "buys time" to stabilize the patient and plan further care.     

"Don''t know" responses in surveys: is what I know what you want to know and do I want you to know it?

The authors present finding from their study of a placement prevention program designed to facilitate addiction treatment for substance-abusing mothers and other primary caregivers reported for child maltreatment. Relationships between involvement in the program, the status of addiction treatment, and the variety of outcomes for caregivers and their children were tested. Findings indicate that nearly half of the participants were able to complete addiction treatment and achieve sobriety. Those who used the program's child day care component were three times more likely to complete treatment. Implications for confronting the problem of substance-abusing caregivers in the child welfare system are drawn.     

Child abuse and dentistry: what you should know

Dentistry must become more aware of its moral, legal and ethical responsibilities in recognizing and reporting child abuse and neglect. All dental professionals must be aware of the seriousness of the problems of child maltreatment, and understand that children do not just get hurt in abuse and neglect, they often die as a direct result of their maltreatment. It has been said that victims of child abuse and neglect fall into only two categories--those who lived through it, and those who did not.     

I know what you did: The effects of interpersonal deviance on bystanders.

Using social information processing theory, we explore how interpersonally directed deviance affects work group members who observe or are aware of these insidious behaviors. In a field study, we find that indirect knowledge of work group member interpersonal deviance leads to subsequent interpersonal deviance of a focal individual. We also find that when work group cohesion is high, direct observation of deviance is more likely to result in subsequent bystander deviance. These findings add concretely to theory and research on the bystander effects of workplace deviance. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Doctor ... what do you know about ALS?

This paper presents an analysis of the reports of heat casualties to Medical Branch, United Kingdom Land Forces (UKLF) for the period 1986-1994. There was a marked reduction in reports for 1990-1993 compared to the remaining period studied. This may have been the result of improved prevention or under-reporting. This data has been compared to the reports of heat casualties occurring in Cyprus from 1990-1994. Forced marches and military runs were the primary activities causing heat casualties in UK compared to military exercises in Cyprus. There were many more severe casualties in UK than in Cyprus. If it is necessary to reduce the annual rate of heat casualties in the Army then changes in policy should be focused on the problem in UK. This should consider the generation of metabolic heat as the primary cause of heat illness as opposed to environmental factors. In overseas commands (eg Cyprus) the relative effects are reversed.     

Getting what you want by revising what you had.

Previous research has demonstrated that people recall their past in ways that exaggerate its consistency with their current condition. It is argued that whether people perceive stability or change in themselves depends, in part, on the theory they invoke to reconstruct their past. Two studies, with 106 undergraduates, addressed the impact of a potentially invalid theory of change on the recall of personal histories. Some Ss participated in a study-skills improvement program that promised more than it delivered. Ss initially evaluated their study skills and then were randomly assigned either to a waiting list control condition or to the study skills program. Three weeks later, all Ss were asked to recall as accurately as possible their initial skills evaluation. Program participants recalled their evaluations as being worse than they had actually reported; waiting list Ss exhibited no systematic bias in recall. Program participants also reported greater improvement in study skills and expected better final exam grades than did waiting list Ss. Actual grades did not differ in either study. Nonetheless, 6 mo later program participants overestimated their academic performance for the term during which the program was conducted. Results support the hypothesis that people can claim support for invalid theories of change by reconstructing their pasts. (23 ref) (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Diagnostic results and their clinical interpretation--or: what you never wanted to know about diagnosis

OBJECTIVE: To analyze HLA-DR4 alleles in New Zealand Polynesians with rheumatoid arthritis (RA). METHODS: Thirty Polynesians and 30 Caucasians with RA, as well as 65 Polynesian and 60 Caucasian healthy blood donors, were DR4 subtyped using the polymerase chain reaction and sequence-specific oligonucleotide probes. RESULTS: The frequency of DR4 (DRB1*04) was increased in both Polynesian (P < 0.001) and Caucasian (P < 0.005) RA patients compared with race-matched controls. Dw4 (DRB1*0401) was detected in 15 of 30 Caucasian patients but only 2 of 30 Polynesian patients (P < 0.001). In Polynesians, RA was associated with Dw15 (DRB1*0405), which was present in 11 of 30 patients and 3 of 65 controls (P < 0.001). Dw13 (DRB1*0403) was the most frequent DR4 allele in healthy Polynesians, but was not significantly associated with RA. CONCLUSION: The predominance of the Dw13 subtype in Polynesians may explain in part the low prevalence of RA in this population. The association of Dw15 with RA in Polynesians supports the hypothesis that the third hypervariable region of DR beta determines susceptibility to RA.     

Just enough to be dangerous: The rest of what you need to know about development.

Examines the roots of popular development approaches and contrasts them with an alternative set of principles and practices that resonate more deeply with both what is known about individual learning and what is required by organizations that need to adapt quickly. New models which focus on the fundamentals of learning are presented. It is concluded that organizations are under pressure to stay abreast of change, to do more with less, and to become more agile and versatile. It is argued that in order to keep pace, an organization's approach to development must undergo a revolution also. To meet these demands, they must shift their focus from tools, programs, and events of development to the goal of continuous learning that is integrated with people's daily work lives.

Confidence and accuracy in person perception: Do we know what we think we know about our relationship partners?

A cross-sectional study of dating partners and a longitudinal study of college roommates revealed that the confidence and accuracy of their impressions were often dissociated. For example, relationship length and degree of involvement tended to increase the confidence of people's impressions, but neither variable consistently increased the accuracy of their impressions of their partners' sexual histories, activity preferences, and so on. A third study showed that relationship length and involvement increased the richness of impressions, and richness fostered confidence. The authors conclude that although confidence-accuracy dissociations are surely problematic in some instances, their apparent pervasiveness raises the possibility that confidence may sometimes contribute to relationship quality even when it is unrelated to accuracy.

The outcomes utility index: will outcomes data tell us what we want to know?

BACKGROUND: Screening for occult blood by means of guaiac tests has an unsatisfactory sensitivity for the detection of colorectal neoplasms. To increase sensitivity and specificity the immunological determination of human hemoglobin and albumin in feces has been developed. The validity of analyzing only two samples from one bowel movement of either test is not known. METHODS: An immunological determination of human fecal hemoglobin and albumin using luminescence immunoassays (LIA) was performed in 739 patients with gastrointestinal complaints before scheduled colonoscopy. Each patient collected two 1 ml samples from one stool. There were no dietary restrictions. RESULTS: The sensitivity for detecting colorectal carcinomas was 95.3% (95% confidence interval 84.2-99.4%) with hemoglobin and 67.4% (95% confidence interval 51.2-80.9%) with albumin. The sensitivity for detecting large adenomatous polyps was 62.9% (95% confidence interval 50.5-74.1%) with hemoglobin and 32.9% (95% confidence interval 22.1-45.1%) with albumin. The specificity was 97% for hemoglobin, 96% for albumin and 94% for the combined test. CONCLUSIONS: The immunological determination of fecal hemoglobin is superior to albumin and has a better sensitivity for the detection of colorectal neoplasms than that reported for guaiac tests, even if two samples from one bowel movement are examined. The immunological determination of fecal hemoglobin should therefore be evaluated for use in colorectal cancer screening.     

Question asking: To know that you do not know is not enough.

Effects of prior knowledge on question asking were examined. Fifth graders with little or much prior knowledge had to indicate the meaning of a set of words. Pupils could (a) not ask a question, (b) ask a global question, or (c) ask a specific question. In Study 1, prior knowledge significantly affected the number of questions asked and the pragmatic significance of the questions. In Study 2, selection was contrasted with production of questions. Pupils with little prior knowledge asked fewer specific questions and more global questions in production. The pragmatic significance of the questions was lower for all pupils in production. The pupils' questions were found wanting in information-gathering and communicative qualities. In Study 2, asking for "provisional answers" in advance of question asking strongly stimulated question asking. It presumably enhances commitment, stimulates monitoring, and alleviates social constraints in asking questions. (PsycINFO Database Record (c) 2010 APA, all rights reserved)
