Japanese Language Students' Attitudes Toward Kanji and Their Perceptions on Kanji Learning Strategies

FOREIGN LANGUAGE ANNALS, Issue 3 2007
Yoshiko Mori
This study aims at identifying interpretable factors underlying Japanese language learners' attitudes toward kanji and their self-reported kanji learning strategies. It also examines the relationship between the two sets of belief factors. A questionnaire survey was conducted among Japanese language students at nine universities in the United States; 311 responses were subjected to exploratory factor analyses that identified six attitudinal factors and six strategy belief factors. Descriptive statistics indicated that students considered rote memorization most effective and metacognitive strategies least effective. Correlational analyses revealed that appreciation of the cultural value of kanji and positive emotions toward kanji were associated with stronger belief in varied strategies. Perception of difficulty and belief in special abilities required for kanji learning, in contrast, were associated with reliance on rote memorization. [source]


Shyness and emotion-processing skills in preschoolers: a 6-month longitudinal study

INFANT AND CHILD DEVELOPMENT, Issue 2 2008
Paul S. Strand
Abstract The present study utilized a short-term longitudinal research design to examine the hypothesis that shyness in preschoolers is differentially related to different aspects of emotion processing. Using teacher reports of shyness and performance measures of emotion processing, including (1) facial emotion recognition, (2) non-facial emotion recognition, and (3) emotional perspective-taking, we examined 337 Head Start attendees twice at a 24-week interval. Results revealed significant concurrent and longitudinal relationships between shyness and facial emotion recognition, and either minimal or non-existent relationships between shyness and the other aspects of emotion processing. Correlational analyses of concurrent assessments revealed that shyness predicted poorer facial emotion recognition scores for negative emotions (sad, angry, and afraid), but not a positive emotion (happy). Analyses of change over time, on the other hand, revealed that shyness predicted change in facial emotion recognition scores for all four measured emotions. Facial emotion recognition scores did not predict changes in shyness. Results are discussed with respect to expanding the scope of research on shyness and emotion processing to include time-dependent studies that allow for the specification of developmental processes.

An examination of the intentional and unintentional aspects of medication non-adherence in patients diagnosed with hypertension

JOURNAL OF CLINICAL NURSING, Issue 4 2007
Elaine Lehane MSc
Aims., The primary aim of this study was to describe the unintentional and intentional aspects of non-adherence in patients diagnosed with hypertension. A secondary aim was to examine the relationships between medication adherence and purposeful actions (intentional non-adherence), patterned behaviours (unintentional non-adherence) and demographic questionnaire variables. Background., Non-adherence to medications continues to be a significant health-care issue, the extent and consequences of which have been well documented. Despite considerable research over the past five decades, little progress has been made in solving this healthcare problem. Recent literature indicates that this lack of progress can be attributed to the fact that past research has concentrated solely upon either the unintentional or the intentional aspects of non-adherence, instead of addressing both facets simultaneously. Methods., A quantitative, descriptive, correlation research design was employed using Johnson's (2002) Medication Adherence Model as a theoretical framework. A convenience sample of 73 participants with hypertension, attending the outpatients' clinics of two university hospitals was recruited. Data were collected by means of a researcher administered questionnaire and analysed using the Statistical Package for Social Sciences. Results., High levels of medication adherence with a mean adherence score of 4·75 (maximum 5) were reported. Low and medium levels of purposeful actions and medium and high levels of patterned behaviours towards medication taking were found. Correlational analyses did not demonstrate statistically significant associations. Conclusions., Both the intentional and unintentional dimensions of medication-taking are simultaneously considered by patients to varying levels when adhering to therapeutic regimens. This is an important research area for nurses as it facilitates an increased understanding of non-adherence and, in so doing, aids the uncovering of more effective interventions aimed at sustaining lifelong pharmacotherapy. Relevance to clinical practice., By acknowledging a broader approach to patient medication-taking, nurses will be able more effectively to assess and intervene in non-adherent behaviours and actions.

Validation of a 28-item version of the Systemic Clinical Outcome and Routine Evaluation in an Irish context: the SCORE-28

JOURNAL OF FAMILY THERAPY, Issue 3 2010
Paul Cahill
This article describes the development, in an Irish context, of a three-factor, twenty-eight-item version of the Systemic Clinical Outcome and Routine Evaluation (SCORE) questionnaire for assessing progress in family therapy. The forty- item version of the SCORE was administered to over 700 Irish participants including non-clinical adolescents and young adults, families attending family therapy, and parents of young people with physical and intellectual disabilities and cystic fibrosis. For validation purposes, data were also collected using brief measures of family and personal adjustment. A twenty-eight-item version of the SCORE (the SCORE-28) containing three factor scales that assess family strengths, difficulties and communication was identified through exploratory principal components analysis. Confirmatory factor analysis showed that the factor structure of the SCORE-28 was stable. The SCORE-28 and its three factor scales were shown to have excellent internal consistency reliability, satisfactory test-retest reliability and construct validity. The SCORE-28 scales correlated highly with the General Functioning Scale of the Family Assessment Device, and moderately with the Global Assessment of Relational Functioning Scale, the Kansas Marital and Parenting Satisfaction Scales, the Satisfaction with Life Scale, the Mental Health Inventory , 5, and the total problems scale of the Strengths and Difficulties Questionnaire. Correlational analyses also showed that the SCORE-28 scales were not strongly associated with demographic characteristics or social desirability response set. The SCORE-28 may routinely be administered to literate family members aged over 12 years before and after family therapy to evaluate therapy outcome. [source]


Neurogenesis in a rat model of age-related cognitive decline

AGING CELL, Issue 4 2004
J. L. Bizon
Summary Age-related decrements in hippocampal neurogenesis have been suggested as a basis for learning impairment during aging. In the current study, a rodent model of age-related cognitive decline was used to evaluate neurogenesis in relation to hippocampal function. New hippocampal cell survival was assessed approximately 1 month after a series of intraperitoneal injections of 5-bromo-2,-deoxyuridine (BrdU). Correlational analyses between individual measures of BrdU-positive cells and performance on the Morris water maze task provided no indication that this measure of neurogenesis was more preserved in aged rats with intact cognitive abilities. On the contrary, among aged rats, higher numbers of BrdU-positive cells in the granule cell layer were associated with a greater degree of impairment on the learning task. Double-labelling studies confirmed that the majority of the BrdU+ cells were of the neuronal phenotype; the proportion of differentiated neurons was not different across a broad range of cognitive abilities. These data demonstrate that aged rats that maintain cognitive function do so despite pronounced reductions in hippocampal neurogenesis. In addition, these findings suggest the interesting possibility that impaired hippocampal function is associated with greater survival of newly generated hippocampal neurons at advanced ages.

God Image and Happiness in Chronic Pain Patients: The Mediating Role of Disease Interpretation

PAIN MEDICINE, Issue 5 2010
Jessie Dezutter dra
Abstract Objective., The present study explored the role of the emotional experience of God (i.e., positive and negative God images) in the happiness of chronic pain (CP) patients. Framed in the transactional model of stress, we tested a model in which God images would influence happiness partially through its influence on disease interpretation as a mediating mechanism. We expected God images to have both a direct and an indirect (through the interpretation of disease) effect on happiness. Design., A cross-sectional questionnaire design was adopted in order to measure demographics, pain condition, God images, disease interpretation, and happiness. One hundred thirty-six CP patients, all members of a national patients' association, completed the questionnaires. Results., Correlational analyses showed meaningful associations among God images, disease interpretation, and happiness. Path analyses from a structural equation modeling approach indicated that positive God images seemed to influence happiness, both directly and indirectly through the pathway of positive interpretation of the disease. Ancillary analyses showed that the negative influence of angry God images on happiness disappeared after controlling for pain severity. Conclusion., The results indicated that one's emotional experience of God has an influence on happiness in CP patients, both directly and indirectly through the pathway of positive disease interpretation. These findings can be framed within the transactional theory of stress and can stimulate further pain research investigating the possible effects of religion in the adaptation to CP. [source]


Intimate social behavior in infant interactions in Cebus apella,

AMERICAN JOURNAL OF PRIMATOLOGY, Issue 1 2009
Gayle Byrne
Abstract The development and individual stability of three intimate social behaviors (Lipsmacking, Carrying Attempts, and Facial Inspection) were examined for 43 group-housed Cebus apella infants from birth to 2 years of age. Occurrence of these behaviors was scored from 10-min videotape samples recorded three times a week over that time. Frequency of Lipsmacking and Carrying Attempts by adult males, adult females, and juveniles were all highest in early months and decreased to low levels by the end of the first year. Facial Inspection of partners by infants, in contrast, first began at 3,4 months and increased over time, at least to adult males and juveniles. Correlational analyses indicated stable individual differences in these interactions with infants and outlined a relationship between these intimate behaviors and more general social patterns reported previously for these animals. Results suggest that adult males may play a special role in affording juveniles opportunities for social learning of foraging and manipulative skills. Am. J. Primatol. 71:77,85, 2009.

Analytic and Heuristic Processing Influences on Adolescent Reasoning and Decision-Making

CHILD DEVELOPMENT, Issue 3 2001
Paul A. Klaczynski
The normative/descriptive gap is the discrepancy between actual reasoning and traditional standards for reasoning. The relationship between age and the normative/descriptive gap was examined by presenting adolescents with a battery of reasoning and decision-making tasks. Middle adolescents (N= 76) performed closer to normative ideals than early adolescents (N=66), although the normative/descriptive gap was large for both groups. Correlational analyses revealed that (1) normative responses correlated positively with each other, (2) nonnormative responses were positively interrelated, and (3) normative and nonnormative responses were largely independent. Factor analyses suggested that performance was based on two processing systems. The "analytic" system operates on "decontextualized" task representations and underlies conscious, computational reasoning. The "heuristic" system operates on "contextualized," content-laden representations and produces "cognitively cheap" responses that sometimes conflict with traditional norms. Analytic processing was more clearly linked to age and to intelligence than heuristic processing. Implications for cognitive development, the competence/performance issue, and rationality are discussed. [source]


Frontoparietal cortical activity of methamphetamine-dependent and comparison subjects performing a delay discounting task

HUMAN BRAIN MAPPING, Issue 5 2007
John R. Monterosso
Abstract Relative to individuals who do not have addictive disorders, drug abusers exhibit greater devaluation of rewards as a function of their delay ("delay discounting"). The present study sought to extend this finding to methamphetamine (MA) abusers and to help understand its neural basis. MA abusers (n = 12) and control subjects who did not use illicit drugs (n = 17) participated in tests of delay discounting with hypothetical money rewards. We then used a derived estimate of each individual's delay discounting to generate a functional magnetic resonance imaging probe task consisting of three conditions: "hard choices," requiring selections between "smaller, sooner" and "larger, later" alternatives that were similarly valued given the individual's delay discounting; "easy choices," in which alternatives differed dramatically in value; and a "no choice" control condition. MA abusers exhibited more delay discounting than control subjects (P < 0.05). Across groups, the "hard choice > no choice" contrast revealed significant effects in the ventrolateral prefrontal cortex, dorsolateral prefrontal cortex (DLPFC), dorsal anterior cingulate cortex, and areas surrounding the intraparietal sulcus (IPS). With group comparisons limited to these clusters, the "hard choice > easy choice" contrast indicated significant group differences in task-related activity within the left DLPFC and right IPS; qualitatively similar nonsignificant effects were present in the other clusters tested. Whereas control subjects showed less recruitment associated with easy than with hard choices, MA abusers generally did not. Correlational analysis did not indicate a relationship between this anomaly in frontoparietal recruitment and greater degree of delay discounting exhibited by MA abusers. Therefore, while apparent inefficiency of cortical processing related to decision-making in MA abusers may contribute to the neural basis of enhanced delay discounting by this population, other factors remain to be identified.

Refining the measurement of exposure to violence (ETV) in urban youth

JOURNAL OF COMMUNITY PSYCHOLOGY, Issue 5 2007
Robert T. Brennan
Correlational analysis, classical test theory, confirmatory factor analysis, and multilevel Rasch modeling were used to refine a measure of adolescents' exposure to violence (ETV). Interpersonal violence could be distinguished from other potentially traumatic events; it was also possible to distinguish three routes of exposure (victimization, witnessing, and learning of). Correlations confirmed that ETV subscales are related to measures of aggression, delinquency, and depression/anxiety. Reliability was improved by combining ETV subscales and/or caregiver and youth reports. Valid and reliable measures of ETV are critical to future research in associating violence exposure with common mental health and behavioral outcomes and disorders, and tracking how early violence exposure may affect future outcomes for adolescents. © 2007 Wiley Periodicals, Inc.

Waiting list management: priority criteria or first-in first-out?

JOURNAL OF EVALUATION IN CLINICAL PRACTICE, Issue 4 2009
A case for total joint replacement
Abstract Background, Total joint replacements are interventions with large waiting times from indication to the surgery management. These patients can be managed in two ways; first-in first-out or through a priority tool. The aim of this study was to compare real time on waiting list (TWL) with a priority criteria score, developed by our team, in patients awaiting joint replacement due to osteoarthritis. Methods, Consecutive patients placed on waiting list were eligible. Patients fulfilled a questionnaire which included items of our priority tool and the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) specific questionnaire. Other priority items were extracted from the clinical history. The priority tool gives a score from 0 to 100 points, and three categories (urgent, preferent and ordinary). We studied the differences among categories and TWL by means of one-way analysis of variance. Correlational analysis was used to evaluate association among priority score and TWL and WOMAC baseline and gains at 6 months with priority score and TWL. Results, We have studied 684 patients. Women represented 62% of sample. The mean age was 70 years. There were not association between the categories of priority score and TWL (P = 0.12). The rho correlation coefficient between TWL and priority score was ,0.11. Among baseline WOMAC scores and priority score, the rho coefficients were 0.79, 0.7 and 0.52 with function, pain and stiffness dimensions, respectively. There were differences in the mean scores of WOMAC dimensions according to the three priority categories (P < 0.001) but no with TWL categories. Data of gains in both health-related quality of life dimensions at 6 months were similar, with differences according to priority categories but no regarding TWL. Conclusions, The results of the study support the necessity of implementing a prioritization system instead of the actual system if we want to manage the waiting list for joint replacement with clinical equity.

Early vocabulary development in deaf native signers: a British Sign Language adaptation of the communicative development inventories

THE JOURNAL OF CHILD PSYCHOLOGY AND PSYCHIATRY AND ALLIED DISCIPLINES, Issue 3 2010
Tyron Woolfe
Background:, There is a dearth of assessments of sign language development in young deaf children. This study gathered age-related scores from a sample of deaf native signing children using an adapted version of the MacArthur-Bates CDI (Fenson et al., 1994). Method:, Parental reports on children's receptive and expressive signing were collected longitudinally on 29 deaf native British Sign Language (BSL) users, aged 8,36 months, yielding 146 datasets. Results:, A smooth upward growth curve was obtained for early vocabulary development and percentile scores were derived. In the main, receptive scores were in advance of expressive scores. No gender bias was observed. Correlational analysis identified factors associated with vocabulary development, including parental education and mothers' training in BSL. Individual children's profiles showed a range of development and some evidence of a growth spurt. Clinical and research issues relating to the measure are discussed. Conclusions:, The study has developed a valid, reliable measure of vocabulary development in BSL. Further research is needed to investigate the relationship between vocabulary acquisition in native and non-native signers. [source]


Accessibility of causal explanations for future positive and negative events in adolescents with anxiety and depression

CLINICAL PSYCHOLOGY AND PSYCHOTHERAPY (AN INTERNATIONAL JOURNAL OF THEORY & PRACTICE), Issue 3 2004
Lisa J. Kagan
Anxious and depressed adults' pessimism about future events has been shown to be underpinned by their ability to think of reasons why future events would or would not happen (see, e.g., Byrne and MacLeod, 1997). This study sought to extend this finding to adolescents by investigating the accessibility of explanations given for future events in adolescents with elevated anxiety and depression scores. A school sample of 11,17 year olds (N = 123) participated. Participants completed self-report measures of anxiety, depression and positive and negative affect. In addition they were given a set of potential future positive and negative events and asked to provide reasons as to why the events would (pro reasons) or would not (con reasons) happen. Anxious participants, relative to controls, generated significantly more pro relative to con reasons for negative events happening and showed a non-significant trend towards the opposite pattern for positive events. Depressed participants showed clear differences from controls in their pattern of accessible explanations for both negative events and positive events. Correlational analysis showed that positive and negative affect had differential relationships to positive and negative cognitions concerning future outcomes. The results suggest that the processes that underlie pessimism in depressed and anxious adults also operate in relatively depressed and anxious adolescents.,Copyright © 2004 John Wiley & Sons, Ltd.

The effect of daily caffeine use on cerebral blood flow: How much caffeine can we tolerate?

HUMAN BRAIN MAPPING, Issue 10 2009
Merideth A. Addicott
Abstract Caffeine is a commonly used neurostimulant that also produces cerebral vasoconstriction by antagonizing adenosine receptors. Chronic caffeine use results in an adaptation of the vascular adenosine receptor system presumably to compensate for the vasoconstrictive effects of caffeine. We investigated the effects of caffeine on cerebral blood flow (CBF) in increasing levels of chronic caffeine use. Low (mean = 45 mg/day), moderate (mean = 405 mg/day), and high (mean = 950 mg/day) caffeine users underwent quantitative perfusion magnetic resonance imaging on four separate occasions: twice in a caffeine abstinent state (abstained state) and twice in a caffeinated state following their normal caffeine use (native state). In each state, there were two drug conditions: participants received either caffeine (250 mg) or placebo. Gray matter CBF was tested with repeated-measures analysis of variance using caffeine use as a between-subjects factor, and correlational analyses were conducted between CBF and caffeine use. Caffeine reduced CBF by an average of 27% across both caffeine states. In the abstained placebo condition, moderate and high users had similarly greater CBF than low users; but in the native placebo condition, the high users had a trend towards less CBF than the low and moderate users. Our results suggest a limited ability of the cerebrovascular adenosine system to compensate for high amounts of daily caffeine use. Hum Brain Mapp 2009. © 2009 Wiley-Liss, Inc. [source]


Relationship between organizational climate and empowerment of nurses in Hong Kong

JOURNAL OF NURSING MANAGEMENT, Issue 3 2002
Esther Mok RN
Aims,The authors explore the relationship between organizational climate and empowerment among the nursing staff of a regional hospital in Hong Kong. The main purpose of the study was to apply the modified Spreitzer measure of empowerment in a hospital and to examine the relationship of organizational climate to perceptions of empowerment. Methods,From 658 questionnaires sent out, 331 nurses participated in the study with a response rate of 50.3%. Survey measures administered included the modified Litwin and Stringer Organizational Climate Questionnaire (LSOCQ) and the modified Spreitzer empowerment instrument. The relationships between organizational climate and empowerment were examined in a series of bivariate correlational analyses. The final section of the questionnaire asked the respondents to list three elements in the organizational climate that they perceived would further increase their feelings of empowerment. Findings,Exploratory factor analysis of the modified LSOCQ resulted in six factors: leadership, working harmony, challenge, recognition, teamwork and decision making. There was a positive correlation between organizational climate and psychological empowerment. Using multiple regression analysis, all the six derived climate factors significantly accounted for 44% of the variance. Among the six predicting factors, leadership and teamwork showed the most positive relationship with psychological empowerment. Responses from the open questions on perception of organizational climate that further enhance nurses' feelings of empowerment were categorized into eight areas. They include leadership, communication, working relationship, recognition, structure, training, teamwork and stress management. Conclusion,The study echoes previous studies in finding that organizational climate and, in particular, supportive leadership and teamwork are related to empowerment. The findings also suggest that the nurses in the study did not put much emphasis on the importance of participative decision making. [source]


Therapist features in sexual offender treatment: their reliable identification and influence on behaviour change

CLINICAL PSYCHOLOGY AND PSYCHOTHERAPY (AN INTERNATIONAL JOURNAL OF THEORY & PRACTICE), Issue 6 2002
W. L. Marshall
In the first of the two studies reported here, we established that trained judges could reliably identify 18 therapist features that occurred with reasonable frequency. In the second study 17 of these features were examined to determine how well they related to changes in sexual offenders with treatment. Five videotapes from each of five different prison programs were rated for the presence of these 17 features and correlational analyses examined their relationship with changes in 44 measures of treatment targets. The primary findings indicated that empathy and warmth displayed by the therapists and their directive and rewarding behaviours, were the features that most strongly predicted therapeutic benefits. The results are discussed in terms of their clinical and research implications. Copyright © 2002 John Wiley & Sons, Ltd. [source]


Linking motivation to personality: causality orientations, motives and self-descriptions

EUROPEAN JOURNAL OF PERSONALITY, Issue 1 2004
Antonella Deponte
This study examines how motives and personality traits differ in people with distinct causality orientations, which refer to the predominant way a person interprets the events that initiate his/her own behaviour. First, a validation of the General Causality Orientation Scale for the Italian language was conducted on 702 undergraduate students. Then, in order to test the hypothesis that causality orientations correspond to different motive patterns and self-descriptions, relations between the GCOS and other constructs were analysed through correlational analysis applied to smaller sub-samples. The conclusion is that the autonomy orientation represents an active and creative way of interacting with the social environment. Conversely, the control and impersonal orientations indicate a lower degree of adjustment and psychological well-being. Conclusions are drawn about the causality orientation theory as a link between personality and motivation. Copyright © 2003 John Wiley & Sons, Ltd. [source]


Body dissatisfaction and drive for thinness in young adult twins

INTERNATIONAL JOURNAL OF EATING DISORDERS, Issue 3 2005
Anna Keski-Rahkonen MD
Abstract Objective We explored correlates of the Eating Disorder Inventory subscales Body Dissatisfaction (BD) and Drive for Thinness (DT) and genetic and environmental influences on these traits. Method In a population-based sample of 4,667 Finnish twins aged 22,27 years, we conducted twin modeling to explore genetic and environmental contributions to body dissatisfaction and drive for thinness. Logistic regression was used for the correlational analysis. Results Various eating and body size-related factors and psychosomatic symptoms were significantly associated with high body dissatisfaction and drive for thinness in both genders. In women, early puberty onset, early initiation of sexual activity, and multiple sex partners were statistically significant risk factors of body dissatisfaction. In gender-specific univariate twin models, additive genes accounted for 59.4% (95% confidence interval [CI] = 53.2,64.7%) of the variance in body dissatisfaction and for 51.0% (95% CI = 43.7,57.5%) of the variance in drive for thinness among females, but for none of the variance among males. Discussion There are very distinct gender differences in the heritability patterns of body dissatisfaction and drive for thinness in young adults. © 2005 by Wiley Periodicals, Inc. [source]


A Model of Adaptive Language Learning

MODERN LANGUAGE JOURNAL, Issue 3 2006
LINDY J. WOODROW
This study applies theorizing from educational psychology and language learning to hypothesize a model of language learning that takes into account affect, motivation, and language learning strategies. The study employed a questionnaire to assess variables of motivation, self-efficacy, anxiety, and language learning strategies. The sample consisted of 275 advanced learners studying English for academic purposes prior to entering Australian universities. The data were analyzed using both variable- and person-centered approaches. The variable-centered approaches included correlational analysis and structural equation modeling, whereas the person-centered approaches utilized cluster analysis and profile analysis using multidimensional scaling (PAMS). The findings supported the hypothesized model of adaptive learning and highlighted the relevance of research in educational psychology for informing language learning research. [source]


The Racial Components of "Race-Neutral" Crime Policy Attitudes

POLITICAL PSYCHOLOGY, Issue 1 2002
Mark Peffley
Past studies have found evidence of a connection between race and crime in the minds of many white Americans, but several gaps remain in our knowledge of this association. Here, a multimethod approach was used to examine more closely the racial component of whites' support for ostensibly race-neutral crime policies. Conventional correlational analysis showed that negative stereotypes of African Americans,specifically, the belief that blacks are violent and lazy,are an important source of support for punitive policies such as the death penalty and longer prison terms. A survey experiment further showed that negative evaluations of black prisoners are much more strongly tied to support for punitive policies than are negative evaluations of white prisoners. These findings suggest that when many whites think of punitive crime policies to deal with violent offenders, they are thinking of black offenders. [source]
