How do scientists select articles in the PubMed database? An empirical study of criteria and strategies

IntroductionThe present study investigated the strategies used by experienced researchers to find articles in an online bibliographic database.ObjectiveThe goal was to shed light on researchers’ actual search behaviour by empirically observing users during the search process.MethodWe asked 16 neuroscience researchers and 16 researchers in other disciplines of life sciences to perform five search tasks on neuroscience topics using the PubMed database. Think-aloud protocols were recorded while the participants performed the search tasks.ResultsAll researchers managed to find adequate references for the tasks in the limited amount of time allocated. Most participants used similar, very basic moves and tactics to perform the tasks. However, they behaved in many different ways when they had to decide whether to read the retrieved results or to modify their query (according to the number of references they obtained), or when selecting the one or two references they finally gave as answers among all possible answers.DiscussionVariability in participants’ behaviour may result from inter-individual differences in either the participants’ mental models of PubMed or cognitive abilities and styles, but the question requires further investigation. The data further suggest that developers of online search engines and databases should concentrate their efforts on improving simple-search interfaces and helping users to correct search errors in real time.     

The Relationships Between Japanese Interpersonal Conflict Styles and Their Language Expressions

ABSTRACT

The present study investigated the influence of interpersonal conflict management styles on language expressions and the differences in expressions in same-sex relational categories based on specific in-group-out-group classifications. Questionnaires were administered to 367 university students in Japan. After reading a scenario, participants reported on actual language use and gave ratings on an interpersonal conflict management scale. The results revealed that Japanese change their expressions, along with psychological styles, depending on the relational target. They also indicated psychological constructs were related to their equivalent expressions. The results suggested that future research should take into consideration the potential differences in behavior and interaction posture inherent in various relational and situational categories.

Assessing decision-making style in French-speaking populations: Translation and validation of the general decision-making style questionnaire

IntroductionIndividual differences in decision-making are a fundamental component of our understanding of the decision-making process. Scott and Bruce (1995) developed the General Decision-Making Style (GDMS) questionnaire to assess five decision-making styles: rational, intuitive, dependent, avoidant, and spontaneous.ObjectiveThe purpose of our study was to translate and validate the GDMS into French. This measure has been used frequently to assess decision-making style since its creation. Yet, the scale is currently unavailable in French despite being already available in Slovak, Italian, and Swedish.MethodFollowing best practices for scale translation (e.g., Vallerand, 1989), the original version of the GDMS was administered to a group of 345 English-speaking participants and the translated version of the questionnaire was administered to a group of 325 French-speaking participants.ResultsThe properties of the translated questionnaire were then compared to those of the original questionnaire. Results of item-level, scale-level and measurement invariance analyses demonstrate that the translated measure, the Échelle des styles décisionnels, is a valid and reliable assessment of decision-making style in French-speaking populations.ConclusionThis measure already exists in languages that are much less commonly spoken than French. The newly translated Échelle des styles décisionnels will now allow researchers to validly assess decision-making style in French-speaking populations, thereby greatly increasing the ability to assess cross-cultural stability of decision-making theories.     

Event-related-potential (ERP) correlates of cognitive styles,abilities and aptitudes

Fifty, right-handed males were given 11 psychometric tests of cognitive styles, abilities and aptitudes. Visual (VERP), auditory (AERP) and bimodal (BERP) brain event-related-potential (ERP) amplitudes were recorded from each of these Ss. Canonical and product-moment correlations were computed. These analyses established that VERPs and BERPs elicited in the frontal, temporal, parietal and occipital regions were related to abilities and aptitudes: general aptitude, reading and verbal comprehension and spatial ability; and a cognitive style: field dependence-independence. The results demonstrated the construct validity of ERPs as indicators of individual differences in cognitive characteristics, especially crystallized and fluid intelligence.     

The Role of Metalinguistic Awareness in the Reading Comprehension of Sixth and Seventh Graders

If reading is viewed as an active cognitive process, then the understanding and evaluation of written material may depend somewhat on the reader's cognitive ability. Furthermore, developmental changes in cognitive ability may be related to changes in reading behavior. This article provides a brief overview of Jean Piaget's theories of cognitive development; characteristics of the formal operational thought period (approximately ages 11‐14) are particularly emphasized. Finally, several studies which have attempted to determine the relationship between formal thought and reading behavior are described and discussed.     

THE SHORT CIRCUIT MODEL OF READING: A SYNTHESIS OF READING THEORIES

Although many reviews of reading theories exist, little has been done to examine the similarities between reading theories so as to create a synthesis of ideas across reading theorists. Even though most of the different theorists have tended to emphasize different aspects of the reading process, upon closer examination they have been dealing with and applying similar assumptions in their work. This article is an attempt to examine both these similar assumptions and their major differences and to synthesize them into a theory comprehensive enough to encompass both. This synthesis is intended as a new perspective from which to begin to study the reading process.     

Exploring the Within-Person Coupling of Reading Vision and Cognition in the Elderly

ABSTRACT

This study examined the within-person relationship between reading vision and cognitive functioning. Analysis was conducted on 36 community-dwelling elderly (age range?=?60–87) who completed a reading vision task and three cognitive tests (i.e., Rey Auditory Verbal Learning Task (AVLT), Letter Series, and Number Comparison) twice a day over 60 consecutive days. Significant within-person variability was found for the reading vision measure. Additionally, a main effect was found for reading vision and performance on the AVLT and Number Comparison task; such that on occasions when reading vision was poor, cognitive performance suffered.     

The mediating effect of reflective-analytic cognitive style on rational thought

Abstract

We investigate whether non-miserly cognitive styles mediate the effects of cognitive ability and thinking dispositions on rational thought. Specifically, we review relevant literature on two dimensions that define non-miserly cognitive style: reflection-impulsivity and analytic-intuitive. We use these two dimensions to identify a continuum of cognitive styles that vary from miserly (impulsive-intuitive) to non-miserly (reflective-analytic) and are congruent with tendencies to commit specific rational thinking errors. Further, we argue that this continuum, which we label reflective-analytic cognitive style, mediates the effect of cognitive ability and thinking dispositions on rational thought. We conduct an experiment testing our predictions and find evidence, via structural equation modelling, that reflective-analytic cognitive style does mediate the effect of cognitive ability (as measured by working memory capacity) and thinking dispositions (as measured by need for cognition and actively open-minded thinking) on responses to traditional rational thinking tasks.     

Developmental dyslexics do not fit in boxes: Evidence from six new case studies

Abstract

Six subjects with a reading problem were tested on a variety of reading and other tasks including tests of phonological awareness and processing, short-term memory, visual analysis and synthesis, memory for faces and pictures, and matching of letters and shapes. The subjects demonstrated differences in their reading strategies, but these showed no relation to any differences in the patterns of deficit on non-reading tasks. Five of them showed severe problems on tasks involving phonological processing and short-term memory but the seventy of these was unrelated to reading strategy. There were some indications of visual weaknesses, but these were severe in only one subject who had a pronounced defect in memory for faces; there was no evidence that the visual weaknesses were consistently related to reading ability or strategy.

It is concluded that all the subjects in this sample (with one 'possible exception) had a deficit in phonological processing but adopted different strategies to cope with this when faced with the task of converting print to sound. Differences in strategy are likely to be affected by the relative efficiency of other cognitive processes, personality and introdctional factors.     

Temperament Styles of Nigerian and U.S. Children

Abstract

Temperament styles of 400 Nigerian children are described in reference to possible gender and age differences and compared with those of 3200 U.S. children in light of Jung's theory of temperament as modified by Myers and Briggs, one that highlights four bipolar qualities: extroversion-introversion, practical-imaginative, thinking-feeling, and organized-flexible styles. Nigerian children generally prefer introverted to extroverted styles, practical to imaginative styles, feeling to thinking styles, and organized to flexible styles. In contrast to males, females are more likely to prefer feeling and organized styles. Age differences are seen only on organized-flexible styles, with a preference for flexible styles increasing with age. In contrast to U.S. children, Nigerian children tend to express higher preferences for introversion, practical, feeling, and organized styles.     

Multidimensional eating profiles associated with personality traits during emerging adulthood: A cluster-analytic approach

IntroductionPersonality traits can give a fuller understanding for eating behaviors, such as food choice, (un)healhty eating.ObjectiveTo examine eating styles with a multidimensional perspective considering cognitive, affective and conative (or behavioral) components of eating styles in emerging adulthood, and how they may be related to the Big Five and impulsivity traits.MethodsSelf-reported questionnaires were used to explore the association between the eating styles, Big five traits and facets of impulsivity among young French adults (n = 450; Mean Age = 20.84 years; SD = 2.4, with 79.6% of women).ResultsOn the basis of cluster analysis, six eating styles were identified: Healthier, Uninhibited, Dysregulated, Stress-related, Restrictive and Ethical restraint eaters. Results suggest that Uninhibited eaters reported lower scores on Conscientiousness and higher scores on Negative and Positive urgency. The Dysregulated group had lower scores on Extraversion, and high scores on Neuroticism, Negative urgency and Lack of premeditation. Restrictive eaters showed low levels of Openness and Lack of premeditation. The Ethical restraint style was characterized by low scores on Agreeableness and Positive urgency. The ability or inability to cope with both emotional distress and positive and negative impulsive behaviors was related to young adult's eating cognitions and behaviors.ConclusionConsidering the existence of subtypes of eaters and separate associated personality-related traits, an individual differences perspective (e.g., age, gender, disposition to control one's emotional experiences) should be incorporated.     

Family assessment: Centripetal and centrifugal family systems

Abstract

A consideration of interactional style is useful to both researchers and clinicians interested in family assessment. This paper offers data and process evaluation scales designed to determine family interactional style, conceptualized as a continuum ranging from centripetal (CP) to centrifugal (CF), and containing at the midpoint a mixed area in which facets of both the CP and the CF styles are found.     

A Quantitative Analysis of Marriage Selection in a Small Group

Abstract

The relationship between teachers' cognitive styles and the kind of leadership style they prefer and the types of occupational stress they experience was explored by obtaining self-reports from 70 elementary school teachers. Analytic teachers preferred principals who were task rather than relationship oriented. Preferences in leadership style appeared to be related to subjects' tendencies to perceive and evaluate situations in particular ways. Compatibility with a principal's leadership style may have depended on how closely the style matched a teacher's fundamental affective and cognitive characteristics.     

La balance optimisme/pessimisme : détermination des styles d’expectations envers le futur en se basant sur la bidimensionnalité du Life Orientation Test–Revised

IntroductionSince the 1980s, two major conceptions of the representation of optimism and pessimism have been disputed: a unidimensional structure and a bidimensional structure.ObjectiveThe bidimensional properties of the LOT-R in French are further explored in order to determine the styles of expectations towards the future according to the levels of optimism and pessimism.MethodA study carried out on a sample of 913 adults from France (72.7% women, M = 41.14 years) proposes (1) to analyze the factorial structure of the instrument, the relationship between the two constructs as well as their separability, (2) to explore the styles of expectations according to the levels of positive and negative expectations by latent profile analysis, (3) to study the influence of socio-demographic factors (age, sex, socio-professional category) on cognitive expectations about the future.ResultsThe confirmatory factor analyzes establish the replicability of the bidimensional latent structure of the instrument across age and gender groups, with the separability between the two constructs increasing with advancing age. The latent profile analysis supports the existence of three styles of expectations towards the future within the sample: the optimistic style, the mixed style and the pessimistic style. The MIMIC model demonstrates that increasing age and socio-professional category are determinants of levels of optimism and pessimism as well as of expectation styles.ConclusionThis research makes it possible to use the styles of expectations towards the future which empirically models the balance between the levels of optimism and pessimism.     

Cognitive psychology in sport: Progress and prospects

ProblemThere has been a recent upsurge of research interest in cognitive sport psychology or the scientific study of mental processes (e.g., mental imagery) in athletes. Despite this interest, an important question has been neglected. Specifically, is research on cognitive processes in athletes influential outside sport psychology, in the “parent” field of cognitive psychology or in the newer discipline of cognitive neuroscience?ObjectivesThe purpose of this paper is to explore the theoretical significance of research on expertise, attention and mental imagery in athletes from the perspective of cognitive psychology and cognitive neuroscience.MethodFollowing analysis of recent paradigm shifts in cognitive psychology and cognitive neuroscience, a narrative review is provided of key studies on expertise, attention and mental imagery in athletes.Results and conclusionsThis paper shows that cognitive sport psychology has contributed significantly to theoretical understanding of certain mental processes studied in cognitive psychology and cognitive neuroscience. It also shows that neuroscientific research on motor imagery can benefit from increased collaboration with cognitive sport psychology. Overall, I conclude that the domain of sport offers cognitive researchers a rich and dynamic natural laboratory in which to study how the mind works.     

Conviction,character and coping: religiosity and personality are both uniquely associated with optimism and positive reappraising

ABSTRACT

Optimism and positive reappraising seemingly mediate religiosity’s association with well-being. Yet past studies linking religiosity and cognitive coping typically use a bivariate design; thereby ignoring rival explanations. Given previous evidence that agreeableness and conscientiousness (personality traits that co-vary with optimism, positive reappraisal usage and religiosity) largely nullify the association between religiosity and social support, hierarchical regression modelling of cross-sectional survey data – Australia (N?=?195), Japan (N?=?931) and the USA (N?=?5999) – is employed to incrementally validate religiosity’s association with optimism and also positive reappraisals. Although religiosity remains a statistically significant predictor of these coping styles, including agreeableness and conscientiousness typically reduces the strength of association. These cross-cultural results lend weight to the hypothesis that religiosity is a potential, albeit small, influence on cognitive coping styles. Prospective research is now needed to establish whether changes in religiosity precede changes in coping as theorised.     

The relationship between dietary restraint and deficits in reasoning about causes of obesity

Abstract

Objective: Increased levels of dietary restraint are associated with deficits on many cognitive tasks. Less is known about how individual differences in restraint influences complex cognition such as reasoning which is the focus of this research.

Design: Two experimental studies are reported. In study 1, participants (n?=?158) completed a causal conditional reasoning task with statements about weight-related and general causal relationships. Study 2 replicated and extended study 1. Participants (n?=?108) completed a causal conditional reasoning task focusing on behavioural causes of weight change or general statements.

Main outcome measure: Causal conditional reasoning task performance.

Results: In study 1, levels of dietary restraint were negatively associated with reasoning abilities for weight-related statements only. Study 2 replicated the negative association between dietary restraint and reasoning finding the effect in both weight-related, and general, causal judgements.

Conclusion: The novel findings show that individual differences in dietary restraint have a wider relationship with cognition than previously demonstrated. Results tentatively support theoretical explanations of a reduction in cognitive capacity, rather than differences in belief, explaining reasoning deficits. These findings open an interesting avenue for research and might have implications for effective decision making about personal health behaviours, such as food choice.     

The Italian Version of the Cognitive Style Indicator and its Association with Decision-Making Preferences

The Cognitive Style Indicator (CoSI) includes 3 cognitive dimensions: creating (flexible, open-ended and inventive), knowing (emphasizing facts, details, objectivity, and rationality), and planning (guided by preferences for certainty and well-structured information). The first aim of this research was to validate the 3-factor structure of the CoSI within the Italian context. The second was to verify whether cognitive styles, as measured by the CoSI, accounted for individual differences in decision-making processes. Two studies were conducted using 2 different samples (n = 549 and n = 397). Confirmatory and multigroup factor analysis corroborated the 3-factor model and the measurement invariance of the instrument across genders. Reliability indices showed good internal consistency, as well as good levels of convergent and discriminant construct validity. Results from structural equation model revealed that cognitive styles, as measured by the CoSI, predicted individual differences in intuitive and deliberative decision-making processes. Findings gave evidence for the validity of the Italian version of the CoSI and for the causal relationship between cognitive styles and decision-making processes. Further research is needed to explore a more comprehensive model that includes, for example, personality.     

RITALIN UPDATE: IMPLICATIONS FOR READING TEACHERS

Ritalin (methylphenidate hydrochloride) is a powerful stimulant drug frequently prescribed for children exhibiting hyperactive behavior, poor attention span, and/or distractibility. Reading teachers and other educators have a particular interest in Ritalin since they frequently have students in their classes taking this medication. The researchers in this study were interested in determining how Ritalin is prescribed for children in educational settings, what dosages seem appropriate, and specifically, what effect Ritalin has on reading achievement. Implications for reading teachers are discussed.
