A plausible connection: Models examining the relations between evaluation,plausibility, and the refutation text effect

Students are often asked to make evaluations of scientific explanations, which may involve judgments about the plausibility of competing alternatives. We examined undergraduate students' critical evaluations and plausibility perceptions of climate change when reading two different types of text: expository and refutation. Our findings show that greater critical evaluation and higher plausibility related to more knowledge after reading, but only with the refutation text. Furthermore, we found that greater plausibility had a stronger effect on knowledge after reading the refutation text, whereas greater background knowledge had a stronger effect on knowledge after reading the expository text. We also examined changes in students' plausibility and knowledge. There was significant changes in plausibility and knowledge with the refutation text, but no significant change in either variable with the expository text. These results suggest that evaluations and judgments about plausibility may be factors contributing to the refutation effect and knowledge reconstruction.     

Impact of mobile-based mentoring,socio-economic background and religion on girls’ attitude and belief towards antisocial behaviour (ASB)

This study examined the impact of mobile-based mentoring, socio-economic background and religion on girl’s attitude and belief towards ASB in Ibadan Oyo State Nigeria. The study adopted a mixed method research design. The participants in the study comprised forty (40) students purposively selected from Ibadan, Oyo State, Nigeria. The platform ( www.gcmentoringinitiative.org ) was adopted for mobile-based mentoring. One research question was raised and three null hypotheses were tested in the study at .05 level of significance. Data were analysed using content analysis for Focus Group Discussion, Analysis of Covariance and Estimated Marginal Means. The results reveal a significant main effect of socio-economic background on girl’s attitude towards ASB. Also, there was no significant impact of mobile-based mentoring on girl’s attitude towards ASB. Based on the findings, using mobiles in mentoring girls could significantly reinforce or change their belief in engaging in antisocial activities. Also, the socio-economic background plays a significant role in determining the attitude and belief of girls in engaging in antisocial activities. Girls’ religion has little or no effect on their belief and attitude towards antisocial behaviours (ASB). Girls from low-income family are susceptible to engage in ASB, while those from wealthy homes are less likely to engage in ASB.     

Stability of retrospective self-reports of child abuse and neglect before and after therapy for child abuse issues

OBJECTIVE: This study is a follow-up to a previously reported outcome study evaluating the efficacy of an emotionally focused therapy for adult survivors of childhood abuse. The present purpose was to evaluate the stability of self-reports of child maltreatment in the context of reduced psychopathology after therapy. The Childhood Trauma Questionnaire (CTQ; Bernstein et al., 1994) was used to measure the extent of child abuse and neglect. METHOD: The CTQ and measures of symptomatology, abuse resolution, and self-esteem were administered at pretreatment to 44 clients and after 6 months of therapy to 33 therapy completers. Post-treatment interviews also assessed changes in clients' perceptions of self and abusive and neglectful others. Analyses examined change on dependent measures, in interviews, and on the CTQ, as well as the test-retest and alpha reliabilities of CTQ factor scales, and the relationship of CTQ factor scales with pretreatment measures of distress. RESULTS: Analyses revealed significant reductions in psychopathology on all dependent measures and reduced self-blame, negatively biased memories, avoidance, and minimization of the abuse after therapy. Reports of abuse and physical neglect on the CTQ remained stable from pre- to post-therapy. All CTQ dimensions demonstrated good internal consistency and convergent validity with trauma-specific measures of distress. CONCLUSIONS: The stability of the CTQ in the context of significantly reduced psychopathology contributes to evidence supporting the accuracy of retrospective self-reports of childhood abuse.     

Influences of income change and parental acceptance on adolescent transgression proneness and peer relations

The present investigation examined whether the adolescent's involvement in a deviant peer context, proneness to commit transgressions, and perceived peer rejection were influenced by family income change (loss, gain, or no change) and adolescent perceptions of parental acceptance. The sample consisted of 110 families selected from a longitudinal study of adolescents in Berlin, West Germany. A multivariate analysis of covariance, controlling for sex of the adolescent, revealed a significant interaction between income change and perceived parental acceptance. Followup univariate tests showed that adolescents in families experiencing a loss or no change in income were more prone to committing transgressions when there was low parental acceptance. Adolescents who felt accepted by parents were uniformly low on transgression proneness, regardless of income change status. The role of perceived parental acceptance in buffering the adolescent from the potentially adverse effects of economic hardship is discussed.     

Erik Erikson’s value orientation stages: A longitudinal study of ethical identity development among kibbutz adolescents

This study examined ethical development among kibbutz adolescents from the perspective of Erik Erikson’s model of value orientation stages. The purpose was threefold: to examine the longitudinal patterns of value-orientation stage change, to assess the impact of kibbutz education on value orientation development, and to clarify the empirical relationship between value orientation and moral judgment stages. The findings suggested that value-orientation stage change was gradual, upward, and with few regressions. Furthermore, there were no significant sex differences. The empirical relationship between value orientation and moral judgment stages varied from early adolescence to early adulthood underscoring the importance of a life-span perspective on moral development.     

Learner instruction,attitudes during class and academic achievement of junior high school students in Korea: a panel analysis

This study examined changes in the structural relationship among learner-centred classes perceived by Korean junior high school students, attitudes during class and academic achievement. A linear change model was identified as optimal, showing a steady increase over time for each parameter. The higher the initial value for learner-centred classes, the higher both the initial value and rate of change was for attitudes during class and academic achievement. The initial values for attitudes during class also had a significant effect on initial values of academic achievement, suggesting that attitudes are important in increasing academic achievement. The rate of change of both learner-centred classes and attitudes during class significantly influenced the rate of change of academic achievement.

Monitoring Reading Component Skills during a Word-Level Intervention for Adolescents with Limited Reading Proficiency

This study examined incremental change for several reading component skills while adolescents were actively learning a word-level intervention and measured pre-/postintervention change in skills. Six ninth graders in two different classes participated during the 2019–2020 academic year. Primary analysis was based on an A-B single-case design across behaviors and participants to observe change in skills proximal to the intervention. Visual analyses of baseline and intervention phase data indicated correlational relationships between the word-level intervention and word identification of multisyllabic words and oral reading fluency. Specifically, an aggregate Tau-U statistical calculation for prosody showed a moderate 0.70 effect size. Secondary analysis indicated a statistically significant group effect for improved strategy knowledge and skill with a 0.90 effect size but no statistically significant group effects for silent reading fluency or sentence comprehension. Discussion includes connections between progress monitoring and reading theory as well as limitations and implications for researchers and practitioners.     

College Students' Preferences for Psychotherapy Across Depression,Anxiety, Relationship,and Academic Problems

The present study examined differences in college students' preferences for processes of change across four kinds of problems: academic, relationship, depression, and anxiety. Two hundred eighteen undergraduates were randomly assigned to complete either an academic problems, relationship problems, depression, or anxiety Processes of Change Questionnaire along with the Attitudes Toward Seeking Professional Psychological Services Scale. Results revealed significant differences for preferred processes of change as a function of problem type. Generally, processes of change were more preferred for depression, anxiety, and relationship problems than for academic problems. Results may assist clinicians in selecting psychotherapeutic interventions to which college students will be most receptive.     

Ethnicity,self-concept,and school belonging: effects on school engagement

This study examined the relationship of self-concept, school belonging, school engagement to school performance of Caucasian- and African-American students. The main purpose is to assess the ethnicity-based differences in these psycho-social constructs and to explore their differential relationship to school achievement in high-school students from different ethnic background. The data were collected through a survey questionnaire in three school divisions in the Southwest region of Virginia of the United States. The results showed significant ethnicity-based difference in self-concept and in school engagement, but no significant difference in school belonging. The achievement differences were also significant, Caucasian students being higher on self-reported grades. In the regression model, self-concept was not a significant predictor of school outcomes, while school belonging had a significant relationship to school achievement for African-American students. Both self-concept and school engagement were significant for Caucasian students. The findings of the study provide better understanding of the relationship of these variables to school achievement and point to some policy-relevant implications.     

爬行经验与母婴依恋行为特点关系的研究

通过对６９名８、９个月婴儿的母亲进行标准化的访谈,考察个体早期自主位移动作──爬行的经验与婴儿对母亲依恋行为特点的关系。结果表明：（１）爬行时间长短与婴儿依恋行为的变化存在非线性的关系。无爬行经验婴儿与会爬４周以内的婴儿在分离敏感性上差异显著;天爬行经验及会爬４周以内的两组婴儿与会爬４周以上的婴儿在依恋行为上均无显著差异。（２）在８个月的婴儿中,会爬的婴儿在与母亲的亲密度、分高敏感性方面的得分显著高于不会爬婴儿;而在９个月婴儿中,会爬与不会爬婴儿依恋母亲的行为没有显著差异,表明爬行经验对婴儿依恋行为的特点有一定影响,而且这种影响与特定年龄阶段有关。     

Schulformwechsel im zweigliedrigen Schulsystem

This study focuses on students who change from the academic to the non-academic school track after grade 7 (probationary year) in Berlin. We examined which individual student characteristics (e.?g., performance, school biography, family background) predict school change after the probationary year. We were particularly interested as to whether there are secondary effects of social background, after controlling for differences in performance. Our analyses were based on data from a study which included a whole cohort of school track changers (N?=?754) who were compared with students that remained at the academic track (N?=?1470). In order to predict the change of school type, multivariate logistic regression analyses were performed. Results revealed significant differences between both groups regarding all observed characteristics. Performance-related characteristics were the best predictors of track change. After controlling for these characteristics, no further significant effects for other predictors were observable (i.?e., no secondary effects of social background were present).     

Navigating puberty,identity, and race among transnationally,transracially adopted Korean American adolescents

This exploratory study examined the relation between pubertal timing and dimensions of ethnic-racial identity among adopted Korean Americans raised transracially in White families. The study also examined whether internalized racism moderated the association between pubertal timing and ethnic-racial identity. Adopted Korean American adolescents (N = 202; 108 females; ages 13–19 years) completed measures of pubertal development, ethnic-racial identity, and internalized racism in 2007. There was no significant main effect of pubertal timing for either male or female adolescents. Internalized racism moderated the relation between pubertal timing and ethnic-racial identity clarity (B = −.16, p = .015) among male adolescents. Specifically, earlier pubertal timing was significantly associated with lower ethnic-racial identity clarity for male adolescents with higher levels of internalized racism.     

Learned helplessness and level of underachievement among deaf adolescents

The purpose of this study was to investigate the effects of a helplessness experience on the subsequent performance of deaf adolescents functioning at mildly underachieving or severely underachieving levels. Sixty deaf adolescents meeting the experimental subject criteria were separated into mildly underachieving or severely underachieving groups of 30 each on the basis of the discrepancy between their individual IQs and 1976 achievement scores. Group members were then randomly assigned to one of three pretreatment situations: a solvable Block Design test; an unsolvable Block Design test; or no pretreatment. A 2 × 3 multivariate analysis of variance posttest only group design then examined the solvable posttest performance of all 60 subjects. Results indicated significantly high posttest error scores among severely underachieving deaf adolescents experiencing an unsolvable pretreatment situation. Recommendations are offered for the practical applications of this research in the classroom.     

The effects of captions on deaf students' content comprehension, cognitive load, and motivation in online learning

The authors examined the effects of captions on deaf students' content comprehension, cognitive load, and motivation in online learning. The participants in the study were 62 deaf adult students who had limited reading comprehension skills and used sign language as a first language. Participants were randomly assigned to either the control group or the experimental group. The independent variable was the presence of captions, and the dependent variables were content comprehension, cognitive load, and motivation. The study applied a posttest-only control group design. The results of the experiment indicated a significant difference (t = -2.16, p < .05) in content comprehension but no statistically significant difference in cognitive load and motivation between the two groups. These results led to suggestions for improvements in learning materials for deaf individuals.     

The Gifted Rating Scales-School Form: A Validation Study Based on Age,Gender, and Race

This study examined the internal consistency and validity of a new rating scale to identify gifted students, the Gifted Rating Scales-School Form (GRS-S). The study explored the effect of gender, race/ethnicity, age, and rater familiarity on GRS-S ratings. One hundred twenty-two students in first to eighth grade from elementary and middle schools in the southeastern United States participated in the investigation. Results indicated high internal consistency for the six GRS-S scales: Intellectual Ability, Academic Ability, Creativity, Artistic Talent, Leadership, and Motivation. Results revealed no effect of race/ethnicity, age, or rater familiarity with the student. There was no significant effect for gender, although a trend was noted for girls rated slightly higher than boys across all scales. This trend was consistent with analyses of the standardization data and with cross-cultural findings using translated versions of the GRS-S. The present findings provided support for the GRS-S as a valid gifted screening instrument.     

Speech intelligibility, loneliness, and sense of coherence among deaf and hard-of-hearing children in individual inclusion and group inclusion

This study examined the sense of coherence and loneliness of 19 children aged 12-14 years with severe to profound hearing loss. These feelings and their interrelations with speech intelligibility (SI) were examined in 2 settings: in special classes within regular schools (group inclusion) or individuals integrated into regular classes (individual inclusion). Two self-report measures (Loneliness Questionnaire and Sense of Coherence Scale) and one SI measure were utilized. Results indicated no significant differences between sense of coherence and loneliness scores of children in the 2 settings. Children in group inclusion received a significantly lower average SI score than did children who were in individual inclusion. Examination of the relations between SI and loneliness and coherence in each educational setting revealed no significant relations among these measures for the children in the group inclusion, whereas significant correlations did emerge for the children who were in individual inclusion. The study emphasized the importance of good SI not only for basic communication but also as a factor that affects the child's social and emotional feelings. In selecting a school setting, it is important to look beyond academic factors and not to ignore the significant effect of SI on the child's well being in school.     

Understanding the Formation, Functions, and Challenges of Grassroots Leadership Teams

This study examined the nature, characteristics, and challenges of grassroots leadership teams and the role of these factors in promoting cognitive complexity in order to provide insight into collective forms of bottom-up change. The study is framed by the literature on leadership teams. Using interviews from a case study conducted at five higher education campuses, we explored two types of leadership teams (sense-making and problem-solving) across different initiatives. The results from this study extend the literature on bottom-up change, leadership, and grassroots teams.     

Process of change during social skills training with preadolescents and its relation to treatment outcome

Videotaped excerpts of treatment sessions from a recent intervention study were examined to explore the changes occurring during social skills training and their relation to treatment outcome. 27 unpopular preadolescents who showed few conversational skills during pretreatment observations engaged in cooperative activities with 2 socially accepted classmates for 10 half-hour sessions. Half of these triads received coaching in conversational skills, while the others received nonspecific adult support during these activities. The quality of social interactions among triad members was evaluated during the sixth and tenth sessions. Children who received social skills training displayed more conversational skills and received more positive peer support during treatment than children who did not receive coaching. Coached children increased skill performance over time while noncoached children did not change. Furthermore, both conversational skills displayed and positive peer responses received during treatment sessions were positively related to treatment outcome.
