Factor structure of intelligence and divergent thinking subtests: A registered report.

Psychologists have investigated creativity for 70 years, and it is now seen as being an important construct, both scientifically and because of its practical value to society. However, several fundamental unresolved problems persist, including a suitable definition of creativity and the ability of psychometric tests to measure divergent thinking-an important component of creativity-in a way that aligns with theory. It is this latter point that this registered report is designed to address. We propose to administer two divergent thinking tests (the verbal and figural versions of the Torrance Tests of Creative Thinking; TTCT) with an intelligence test (the International Cognitive Ability Resource test; ICAR). We will then subject the subscores from these tests to confirmatory factor analysis to test which of nine theoretically plausible models best fits the data. When this study is completed, we hope to better understand whether the degree to which the TTCT and ICAR measure distinct constructs. This study will be conducted in accordance with all open science practices, including pre-registration, open data and syntax, and open materials (with the exception of copyrighted and confidential test stimuli).

A taxonomy of mental time travel and counterfactual thought: Insights from cognitive development.

Humans often engage in complex thought about the past, present, and future. They not only think about what did happen, is happening, and will happen, but also what did not happen, is not happening, and will not happen. Here we present an integrated taxonomy of mental time travel and counterfactual thought, in which event representations are assigned categorically distinct temporal locations (i.e., past, present, or future) and subjective propositional values (i.e., affirmed, negated, or uncertain). We review research on children's developing abilities to generate and reason about event representations with these characteristics. We find that children's development typically proceeds in three stages: (1) the capacity to imagine and reflect on affirmed and uncertain past, present, and future outcomes, (2) the capacity to imagine and reflect on counterfactual, negated versions of known past outcomes and present situations, and (3) the capacity to anticipate experiencing counterfactual emotions (i.e., regret and relief) in the future. This protracted developmental trajectory may be a function of increasing executive demands, increasing hierarchical complexity of temporal representations, or both.

Flexible or leaky attention in creative people? Distinct patterns of attention for different types of creative thinking.

Creativity has been putatively linked to distinct forms of attention, but which aspects of creativity and which components of attention remains unclear. Two experiments examined how divergent thinking and creative achievement relate to visual attention. In both experiments, participants identified target letters (S or H) within hierarchical stimuli (global letters made of local letters), after being cued to either the local or global level. In Experiment 1, participants identified the targets more quickly following valid cues (80% of trials) than following invalid cues. However, this smaller validity effect was associated with higher divergent thinking, suggesting that divergent thinking was related to quicker overcoming of invalid cues, and thus to flexible attention. Creative achievement was unrelated to the validity effect. Experiment 2 examined whether divergent thinking (or creative achievement) is related to "leaky attention," so that when cued to one level of a stimulus, some information is still processed, or leaks in, from the non-cued level. In this case, the cued stimulus level always contained a target, and the non-cued level was congruent, neutral, or incongruent with the target. Divergent thinking did not relate to stimulus congruency. In contrast, high creative achievement was related to quicker responses to the congruent than to the incongruent stimuli, suggesting that real-world creative achievement is indeed associated with leaky attention, whereas standard laboratory tests of divergent thinking are not. Together, these results elucidate distinct patterns of attention for different measures of creativity. Specifically, creative achievers may have leaky attention, as suggested by previous literature, whereas divergent thinkers have selective yet flexible attention.

Pattern recognition as a concept for multiple-choice questions in a national licensing exam.

BACKGROUND: Multiple-choice questions (MCQ) are still widely used in high stakes medical exams. We wanted to examine whether and to what extent a national licensing exam uses the concept of pattern recognition to test applied clinical knowledge. METHODS: We categorized all 4,134 German National medical licensing exam questions between October 2006 and October 2012 by discipline, year, and type. We analyzed questions from the four largest disciplines: internal medicine (n = 931), neurology (n = 305), pediatrics (n = 281), and surgery (n = 233), with respect to the following question types: knowledge questions (KQ), pattern recognition questions (PRQ), inverse PRQ (IPRQ), and pseudo PRQ (PPRQ). RESULTS: A total 51.1% of all questions were of a higher taxonomical order (PRQ and IPRQ) with a significant decrease in the percentage of these questions (p <0.001) from 2006 (61.5%) to 2012 (41.6%). The proportion of PRQs and IPRQs was significantly lower (p <0.001) in internal medicine and surgery, compared to neurology and pediatrics. PRQs were mostly used in questions about diagnoses (71.7%). A significantly higher (p <0.05) percentage of PR/therapy questions was found for internal medicine compared with neurology and pediatrics. CONCLUSION: The concept of pattern recognition is used with different priorities and to various extents by the different disciplines in a high stakes exam to test applied clinical knowledge. Being aware of this concept may aid in the design and balance of MCQs in an exam with respect to testing clinical reasoning as a desired skill at the threshold of postgraduate medical education.

Development and assessment of brief versions of the Penn State Worry Questionnaire and the Ruminative Response Scale.

OBJECTIVES: Worry and depressive rumination have been found to be involved in the onset and maintenance of a range of psychological disorders. The development of brief screening measures for excessive worry and depressive rumination is therefore desirable to facilitate the assessment of worry and rumination in prevention and treatment settings where routine administration of full questionnaires is not practical due to time-related constraints. DESIGN AND METHODS: Using the Penn State Worry Questionnaire (PSWQ) and the Ruminative Response Scale (RRS) as gold standard starting points, brief versions of these measures were developed in a large sample of adolescents (N = 1,952) and results were cross-validated in two independent samples (N = 1,954; N = 457). RESULTS: The brief versions demonstrated acceptable to high internal consistency (brief PSWQ: α = .84-.91; brief RRS: α = .78-.81) and correlated highly with the full questionnaires (brief PSWQ: r = .91-.94; brief RRS: r = .88-.91). In addition, they showed high sensitivity (brief PSWQ: .90-.92; brief RRS: .90-.93), and high specificity (brief PSWQ: .88-.90; brief RRS: .80-.87) to detect excessive worry and rumination. The validity of the brief measures was further supported by demonstrating that the brief measures showed similar differences in scores between males and females as the full measures as well as substantial relationships to other measures of repetitive negative thinking and symptom measures of anxiety and depression. Finally, the brief measures predicted future symptoms of anxiety and depression. CONCLUSIONS: The brief versions of the PSWQ and RRS are time-efficient and valid instruments for the screening of worry and depressive rumination. Their use in clinical practice is recommended to inform treatment and/or to select individuals at risk for development of psychological disorders who may benefit from preventive interventions.

If only I had taken my usual route : age-related differences in counter-factual thinking.

Previous research suggests that young adults can shift between rational and experiential modes of thinking when forming social judgments. The present study examines whether older adults demonstrate this flexibility in thinking. Young and older adults completed an If-only task adapted from Epstein, Lipson, and Huh's (1992 , Journal of Personality and Social Psychology, 62, 328) examination of individuals' ability to adopt rational or experiential modes of thought while making a judgment about characters who experience a negative event that could have been avoided. Consistent with our expectations for their judgments of the characters, young adults shifted between experiential and rational modes of thought when instructed to do so. Conversely, regardless of the mode of thought being used or the order with which they adopted the different modes of thought (i.e., shifting from experiential to rational in Study 1 and from rational to experiential in Study 2), older adults consistently offered judgments and justifications that reflected a preference for experiential-based thought.

The impact of help seeking on individual task performance: the moderating effect of help seekers' logics of action.

Drawing from achievement-goal theory and the social psychological literature on help seeking, we propose that it is the variance in the logic underpinning employees' help seeking that explains divergent findings regarding the relationship between help seeking and task performance. Using a sample of 110 newly hired customer contact employees, a prospective study design, and archival performance data, we found no evidence of a hypothesized main effect of help seeking on performance. However, we did find that the help seeking-performance relationship was conditioned by the degree to which help seekers endorse 2 alternative help-seeking logics (autonomous vs. dependent logic) such that the level of help seeking is more strongly related to performance among those either more strongly endorsing an autonomous help-seeking logic or more weakly endorsing a dependent help-seeking logic.

[Intellectual styles and academic achievement: a developmental perspective]. / Estilos intelectuales y rendimiento académico: una perspectiva evolutiva.

The aim of the present study is to provide additional information to highlight some aspects concerning the relationship between thinking styles and academic achievement. In order to understand the extent to which thinking styles predict academic achievement, 1466 students, between 12 and 16 years old, from first to fourth grades of Compulsory Secondary Education (Spanish ESO) took part in the research. A parsimonious model of covariances was assumed in each of the four samples corresponding to the four different grades of Secondary School as well as in the total sample. Data show that thinking styles significantly explain part of the variance of academic achievement, although only about 10%.

The measurement of "eating-disorder-thoughts" and "eating-disorder-behaviors": Implications for assessment and detection of eating disorders in epidemiological studies.

To test a theoretically driven second-order factor model of eating disorders, with eating-disordered thoughts and eating-disordered behaviors representing the higher order factors, we conducted a confirmatory factor analysis using a female university student sample (N=1816). The 'Thought' latent construct was comprised of indicators representing fear of fat and dissatisfaction with body shape/weight and the latent construct 'Behavior' was comprised of indicators representing binging, purging and restricting. From the thought and behavior latent factors, composite groups were created by varying the level of thoughts and behaviors (high, moderate, and few/or none). We examined the independent contributions of thoughts and behaviors on a measure of psychopathology (depression). A second-order model of "eating disorder thoughts" and "eating disorder behaviors" was supported by the data, based on model fit, factor loadings, and model parsimony. Mean scores on depression were clinically significant for groups engaged in any level of eating disorder behavior whereas thoughts contributed to risk for depression only at the extreme end. Because of the disproportionate representation of eating disorder thoughts (high) and eating disorder behaviors (low) in non-clinical populations, the measurement and detection of eating disorders may be enhanced by measuring thoughts separate from behaviors.

Asynchronous BCI and local neural classifiers: an overview of the Adaptive Brain Interface project.

In this communication, we give an overview of our work on an asynchronous brain-computer interface (where the subject makes self-paced decisions on when to switch from one mental task to the next) that responds every 0.5 s. A local neural classifier tries to recognize three different mental tasks; it may also respond "unknown" for uncertain samples as the classifier has incorporated statistical rejection criteria. We report our experience with 15 subjects. We also briefly describe two brain-actuated applications we have developed: a virtual keyboard and a mobile robot (emulating a motorized wheelchair).

[Questions about questions: cognitive survey of questionnaire development]. / Fragen über Fragen: cognitive survey in der Fragebogenentwicklung.

OBJECTIVES: Traditional pretests are used in the development of survey items to identify technical and comprehension problems. Cognitive processes involved in answering survey questions are not the object of this kind of test. METHODS: Cognitive survey methods were used here to test a questionnaire screening for rehabilitation needs in people suffering from back pain. Essential techniques of cognitive testing (think-aloud, probing, confidence ratings) are outlined. We applied these techniques to 20 patients suffering from either acute or chronic back pain in order to test the survey. RESULTS: The main goal, i.e., identifying problems in item formulation by means of cognitive testing, was achieved. Almost one third of the survey questions were rephrased according to the results of the study. Some of the improvements of the questionnaire are illustrated. CONCLUSIONS: The increased effort required to perform cognitive testing as compared to traditional pretesting pays off. The two methods have specific pros and cons and cannot replace one another.

Measurement of delusional ideation in the normal population: introducing the PDI (Peters et al. Delusions Inventory).

The Peters et al. Delusions Inventory (PDI) was designed to measure delusional ideation in the normal population, using the Present State Examination as a template. The multidimensionality of delusions was incorporated by assessing measures of distress, preoccupation, and conviction. Individual items were endorsed by one in four adults on average. No sex differences were found, and an inverse relationship with age was obtained. Good internal consistency was found, and its concurrent validity was confirmed by the percentages of common variance with three scales measuring schizotypy, magical ideation, and delusions. PDI scores up to 1 year later remained consistent, establishing its test-retest reliability. Psychotic inpatients had significantly higher scores, establishing its criterion validity. The ranges of scores between the normal and deluded groups overlapped considerably, consistent with the continuity view of psychosis. The two samples were differentiated by their ratings on the distress, preoccupation, and conviction scales, confirming the necessity for a multidimensional analysis of delusional thinking. Possible avenues of research using this scale and its clinical utility are highlighted.

Validation of the French translation of the agoraphobic cognitions questionnaire.

BACKGROUND: The goal of the present study was to validate the French version of the Agoraphobic Cognitions Questionnaire (ACQ). METHODS: Subjects consisted of 115 patients with panic disorder and agoraphobia, 54 obsessive-compulsive patients and 72 normal controls. Patients were referred for outpatient treatment. They filled in the questionnaire before and after entering treatment. The control group consisted of people taken from the general population. It was matched with the clinical groups on age, sex and education. RESULTS: The ACQ appears to have a constant factor structure across US, Dutch and French samples. Results support the validity of the total score of the ACQ. Patients with panic disorder and agoraphobia scored significantly higher than obsessive-compulsive patients and control subjects. On the ACQ physical concerns subscale agoraphobic patients were significantly different from obsessive-compulsive patients and control subjects. On the social/behavioural subscale agoraphobic patients and obsessive-compulsive patients were significantly different from control subjects. The French translation of the ACQ was found to be stable over an interval of 15 days in the control group. The Cronbach coefficients of both subscales were also satisfactory. These results support the stability and the internal consistency of the questionnaire. In addition, the French translation of the ACQ was sensitive to changes with cognitive-behavioural therapy. CONCLUSIONS: These results support the findings of Chambless and Gracely [Cogn Ther Res 1989;13:9-20]. The ACQ physical concerns subscale is a specific feature for the anxiety status experienced by patients with panic disorder and agoraphobia. The ACQ social/behavioural subscale seems to be a more general feature of anxious patients.

Suicidal ideation in elderly bereaved: the role of complicated grief.

This study examined whether symptoms of complicated grief at baseline predicted suicidal ideation during a depressive episode in elderly bereaved individuals. Over a 17-month period, serial ratings of suicidal ideation, hopelessness, and symptoms of depression, anxiety, and complicated grief were obtained from 130 elderly participants who had lost their spouses within the past 2 years. Groups of active and passive suicidal ideators, as well as nonideator controls, were compared via analysis of variance (ANOVA) with respect to levels of complicated grief, depression, and anxiety. Elderly bereaved with both active and passive suicidal ideation were found to have higher symptomatic levels of depression, hopelessness, complicated grief, and anxiety, as well as lower levels of perceived social support, than nonideators at study entry. Fifty-seven percent of the patients with high complicated grief scores were found to be ideators during the follow-up versus 24% of the patients with low complicated grief scores. Patients with any suicidal ideation had higher symptom levels of depression, anxiety, and complicated grief when they were ideators as compared with periods when they denied ideation. Fifteen out of the 39 ideators had recurrent depressive episodes versus 5 of the 91 nonideators. Patients with a history of suicide attempts were more likely to be ideators after loss than other bereaved. Thus, the condition of having high levels of complicated grief symptoms and depressive symptoms appears to make bereaved individuals vulnerable to suicidal ideation. Detection of high levels of complicated grief could help clinicians identify patients who may be at heightened risk for suicide.

Dichotomous thinking in nuclear medicine technology.

Dichotomous thinking is the natural human tendency to think in a binary manner (either-or). Although it is natural, dichotomous thinking can be simplistic and may lead to a lack of consideration of alternatives. In nuclear medicine, a predominant use of dichotomous thinking can lead to a very elementary way of thinking that may produce technologists who do not question why or how things are done. Adaptation and survival in today's health care environment require complex ways of thinking. This article describes dichotomous thinking and its problems and pitfalls in nuclear medicine practice and education, and suggests that dichotomous thinking can be extended to dialectical (contradictory ideas) modes of thinking.
