Cognitive capacities of older adults who are asked to consent to medical treatment or to clinical research

Knowledge about cognitive changes characteristically found in older adults provides necessary context for administering consent procedures. It should neither be assumed that most adults over a certain age are too demented to consent nor that decision-making is approached the same way by younger and older adults.     

Thinking styles and modes of thinking: implications for education and research

The author investigated the relationship of thinking styles to modes of thinking. Participants were 371 freshmen (aged 18 and 19) from the University of Hong Kong. Participants responded to the Thinking Styles Inventory (R. J. Sternnberg & R. K. Wagner, 1992) and the Style of Learning and Thinking (Youth Form; E. P. Torrance, B. McCarthy, & M. T. Kolesinski, 1988). A major finding was that creativity generating and complex thinking styles were significantly positively correlated with the holistic mode of thinking but significantly negatively correlated with the analytic mode of thinking. Thinking styles that denote the tendency to norm favoring and simplistic information processing were significantly positively correlated with the analytic mode of thinking and significantly negatively correlated with the holistic mode of thinking. In a preliminary conclusion, it appears that the thinking style construct overlaps the mode of thinking construct. Implications of this finding for teachers and researchers are delineated.     

Functional anatomy of speech perception and speech production: psycholinguistic implications

This paper presents evidence for a new model of the functional anatomy of speech/language (Hickok & Poeppel, 2000) which has, at its core, three central claims: (1) Neural systems supporting the perception of sublexical aspects of speech are essentially bilaterally organized in posterior superior temporal lobe regions; (2) neural systems supporting the production of phonemic aspects of speech comprise a network of predominately left hemisphere systems which includes not only frontal regions, but also superior temporal lobe regions; and (3) the neural systems supporting speech perception and production partially overlap in left superior temporal lobe. This model, which postulates nonidentical but partially overlapping systems involved in the perception and production of speech, explains why psycho- and neurolinguistic evidence is mixed regarding the question of whether input and output phonological systems involve a common network or distinct networks.     

Cognitive burden of survey questions and response times: A psycholinguistic experiment

An important objective in survey question design is to write clear questions that respondents find easy to understand and to answer. This contribution identifies the factors that influence question clarity. Theoretical and empirical evidence from psycholinguistics suggests that specific text features (e.g., low‐frequency words (LFRWs), left‐embedded syntax) cause comprehension difficulties and impose a high cognitive burden on respondents. To examine the effect of seven different text features on question clarity, an online experiment was conducted in which well‐formulated questions were compared to suboptimal counterparts. The cognitive burden of the questions was assessed with response times. Data quality was compared in terms of drop‐out rates and survey satisficing behaviour. The results show that at least six of the text features are relevant for the clarity of a question. We provide a detailed explanation of these text features and advise survey designers to avoid them when crafting questions. Copyright © 2009 John Wiley & Sons, Ltd.     

Ten commandments for long-term maintenance of acceptable self-help skills for persons who are hard-core stutterers

Hard-core stutterers require long-term self-help maintenance skills. In spite of how successful the laboratory achievement of fluency skills is, it is inevitable that some stuttering either remains or returns after termination of therapy. Most successful programs develop self-help skills so that the severe stutterer can continue to generate acceptable speech. This maintenance program is intended to complement any therapy and integrates the stutterers self-help skills into his or her life-style.     

Cognitive style and suicidal behaviour: implications for therapeutic intervention, research lacunae and priorities

Cognitive style is a well-established theoretical construct but there is considerable ambiguity in the way it has been used and uncertainty regarding the nature of its role in suicide. There is no evidence that specific cognitive dispositions prime people for suicide but there are indications that suicide is associated with a constriction in cognitive style. This constriction leads to decrements in problem-solving and information processing that can be addressed in therapeutic contexts. To help a suicidal person become a better problem-solver is not a trivial task but the evidence suggests that enriching cognitive styles through the development of thinking skills is possible when the therapy session is construed as a learning collaboration.     

Strengths and distress in adults who are aging with HIV: a pilot study

In this qualitative pilot study, distress and strengths associated with aging with Human Immunodeficiency Virus (HIV) were identified for 12 participants. Potential sources of distress were fear of death, financial worries, fear of disclosure, stigma, and long-term coping. Strengths were hardiness, renewed spirituality, social support, community service, and openness to aging. Ways of mitigating these barriers and accentuating these strengths can be explored by mental health professionals if extended with a representative larger sample.     

The state of mentoring research: A qualitative review of current research methods and future research implications

Research regarding mentoring relationships has flourished during the past 20 years. This article reviews the methodology and content of 200 published mentoring articles. Some of the major concerns raised in this review include over reliance on cross-sectional designs and self-report data, a failure to differentiate between different forms of mentoring (e.g., formal versus informal), and a lack of experimental research. Implications and suggestions for future research are offered.

LEX I and II: Two databases of surface word forms for psycholinguistic research in Spanish

Two databases of Spanish surface word forms are presented. Surface word forms are words considered as orthographically or phonologically specified without reference to their meaning or syntactic category. The databases are based on the productive written vocabulary of children between the ages of 6 and 10 years. Statistical and structural information is presented concerning surface word-form frequency, consonant-vowel (CV) structure, number of syllables, syllables, syllable CV structure, and subsyllabic units. LEX I was intended to aid in the study of reading processes. Entries were orthographic surface word forms; words were divided in their components following orthographic criteria. LEX II was designed for spoken language research. Accordingly, words were transcribed phonologically and phonological criteria were applied in extracting the internal units. Information about stress location was also provided. Together, LEX I and LEX II represent a useful tool for psycholinguists interested in the study of people acquiring Spanish as a first or foreign language and of Spanish-speaking populations in general.     

Learning to read facilitates the retrieval of phonological representations in rapid automatized naming: Evidence from unschooled illiterate,ex‐illiterate,and schooled literate adults

Rapid automatized naming (RAN) of visual items is a powerful predictor of reading skills. However, the direction and locus of the association between RAN and reading is still largely unclear. Here, we investigated whether literacy acquisition directly bolsters RAN efficiency for objects, adopting a strong methodological design, by testing three groups of adults matched in age and socioeconomic variables, who differed only in literacy/schooling: unschooled illiterate and ex‐illiterate, and schooled literate adults. To investigate in a fine‐grained manner whether and how literacy facilitates lexical retrieval, we orthogonally manipulated the word‐form frequency (high vs. low) and phonological neighborhood density (dense vs. spare) of the objects' names. We observed that literacy experience enhances the automaticity with which visual stimuli (e.g., objects) can be retrieved and named: relative to readers (ex‐illiterate and literate), illiterate adults performed worse on RAN. Crucially, the group difference was exacerbated and significant only for those items that were of low frequency and from sparse neighborhoods. These results thus suggest that, regardless of schooling and age at which literacy was acquired, learning to read facilitates the access to and retrieval of phonological representations, especially of difficult lexical items.     

Cognitive processing in literate and illiterate subjects: a review of some recent behavioral and functional neuroimaging data

The study of illiterate subjects, which for specific socio-cultural reasons did not have the opportunity to acquire basic reading and writing skills, represents one approach to study the interaction between neurobiological and cultural factors in cognitive development and the functional organization of the human brain. In addition the naturally occurring illiteracy may serve as a model for studying the influence of alphabetic orthography on auditory-verbal language. In this paper we have reviewed some recent behavioral and functional neuroimaging data indicating that learning an alphabetic written language modulates the auditory-verbal language system in a non-trivial way and provided support for the hypothesis that the functional architecture of the brain is modulated by literacy. We have also indicated that the effects of literacy and formal schooling is not limited to language related skills but appears to affect also other cognitive domains. In particular, we indicate that formal schooling influences 2D but not 3D visual naming skills. We have also pointed to the importance of using ecologically relevant tasks when comparing literate and illiterate subjects. We also demonstrate the applicability of a network approach in elucidating differences in the functional organization of the brain between groups. The strength of such an approach is the ability to study patterns of interactions between functionally specialized brain regions and the possibility to compare such patterns of brain interactions between groups or functional states. This complements the more commonly used activation approach to functional neuroimaging data, which characterize functionally specialized regions, and provides important data characterizing the functional interactions between these regions.     

Sixty years of fear appeal research: Current state of the evidence

Fear arousal is widely used in persuasive campaigns and behavioral change interventions. Yet, experimental evidence argues against the use of threatening health information. The authors reviewed the current state of empirical evidence on the effectiveness of fear appeals. Following a brief overview of the use of fear arousal in health education practice and the structure of effective fear appeals according to two main theoretical frameworks—protection motivation theory and the extended parallel process model—the findings of six meta‐analytic studies in the effectiveness of fear appeals are summarized. It is concluded that coping information aimed at increasing perceptions of response effectiveness and especially self‐efficacy is more important in promoting protective action than presenting threatening health information aimed at increasing risk perceptions and fear arousal. Alternative behavior change methods than fear appeals should be considered.     

Spatial and temporal processing in healthy aging: implications for perceptions of driving skills

Sensitivity to the attributes of a stimulus (form or motion) and accuracy when detecting rapidly presented stimulus information were measured in older (N = 36) and younger (N = 37) groups. Before and after practice, the older group was significantly less sensitive to global motion (but not to form) and less accurate on a rapid sequencing task when detecting the individual elements presented in long but not short sequences. These effect sizes produced power for the different analyses that ranged between 0.5 and 1.00. The reduced sensitivity found among older individuals to temporal but not spatial stimuli, adds support to previous findings of a selective age-related deficit in temporal processing. Older women were significantly less sensitive than older men, younger men and younger women on the global motion task. Gender effects were evident when, in response to global motion stimuli, complex extraction and integration processes needed to be undertaken rapidly. Significant moderate correlations were found between age, global motion sensitivity and reports of perceptions of other vehicles and road signs when driving. These associations suggest that reduced motion sensitivity may produce functional difficulties for the older adults when judging speeds or estimating gaps in traffic while driving.     

Barriers and facilitators of physical activity and sport participation among young transgender adults who are medically transitioning

Background: Transgender people (those who feel incongruence between the gender they were assigned at birth and their gender identity) engage in lower levels of physical activity compared to cisgender (non-transgender) people. Several factors have been shown to affect physical activity engagement in the cisgender population; however, the physical activity experiences of young transgender adults have not been explored. It is therefore the aim of the current study to understand what factors are associated with physical activity and sport engagement in young transgender adults who are medically transitioning.

Method: Semi-structured interviews were conducted with 14 young transgender adults (18–36 years) who had initiated their medical transition at a transgender health service in the United Kingdom. The data were analyzed using thematic analysis.

Results: Two main themes were identified: (1) barriers and (2) facilitators to physical activity and sport. Overall, the young transgender adults were insufficiently active due to inadequate changing facilities, body dissatisfaction, fears surrounding “passing” and not being accepted by others. At the same time, participants were motivated to engage in physical activity to increase their body satisfaction and gender congruence. However, participants felt there was a lack of safe and comfortable spaces to engage in physical activity and sport.

Conclusion: Young transgender adults who are medically transitioning experience several barriers to physical activity and sport, despite being motivated to be physically active. Initiatives to facilitate young transgender adults' ability to put their motivations into practice (i.e. to be more physically active) are needed.     

Development of student creative skills: A quest for successful science education

Abstract:

Twelve middle school teachers taught one section of science in a Science‐Technology‐Society (STS) context and another in a more traditional manner organized around typical concepts of science. Because science is concerned with exploring and questioning, trying to explain, and devising tests for such explanations, there is an obvious tie to Creative Problem Solving. Students (314 in twelve class settings) who experienced science as concepts to be considered were compared to students (326 in twelve class settings) who experienced science by considering contemporary issues and student generated questions. Pre‐ and posttest measures were taken on the quantity and uniqueness of student generated questions, possible causes, and predicted consequences for a discrepant presented event. Students in the STS classes consistently showed greater growth in terms of (a) total number of questions generated; (b) number of unique questions; (c) total number of causes suggested; (d) uniqueness of the causes suggested; (e) total number of possible consequences predicted; and (f) uniqueness of the consequences.     

Cognitive modeling of consultation processes: A means for improving consultees'' problem definition skills

This study investigated whether consultees' understanding and use of problem definition skills could be enhanced by increasing their awareness of these processes during consultation interactions. Subjects assigned to a consultation with cognitive modeling group viewed videotaped consultation interactions in which consultants' verbalizations during the problem definition stage of consultation frequently included overt references to the problem-solving processes being used by these consultants. Subjects in a consultation without cognitive modeling group viewed similar interactions except that the consultants' statements did not include overt references to problem-solving processes. A control group viewed irrelevant interactions between consultants and consultees. Data analyses indicated that the subjects exposed to consultations that included cognitive modeling components wrote better problem definitions and were better able to describe the process for defining children's problems than subjects in either the consultation without cognitive modeling or control groups. The subjects in the consultation without cognitive modeling group generally did better than those in the control group.
