This investigation focused on elementary-aged (first and fourth grade) children's individual preferences for narrative and expository text and perceptions of what their same-aged peers would like to read. Preferences and perceptions of text were examined through the lenses of social constructivist and engaged reading theories. The overall purpose of this study was to examine elementary students' preferences for and perceptions about narrative and expository text. This study was a systematic replication and extension of Chapman, Filipenko, McTavish, and Shapiro's (2007) research in British Columbia with first graders. Two individually administered book preference (Open and Closed) tasks and interviews were administered to 84 students. Findings revealed gender and grade level profiles in terms of preferences, perceptions, and rationales for their book choices. As expected, both first and fourth grade boys demonstrated a strong preference for expository text, however, the fourth grade boys also showed a growing preference for narrative text as well. In contrast, both first and fourth grade girls demonstrated a strong preference for both narrative and expository text. For both boys and girls, book topic and pictures/illustrations were the two top categories that drew the children's interest and resulted in the most conversations. Results are discussed in light of implications for instruction, assessment, and future research. 相似文献

The effectiveness of fixed-time delivery of attention to increase the on-task behavior of 2 students in general education
was examined. The teacher in this study provided attention to students on a 5-min fixed-time schedule and responded to students
in her typical manner between cued intervals. An ABAB withdrawal design was used to test the effects of the intervention.
The results of this study indicate that a fixed-time schedule of attention was effective in increasing students’ on-task behavior
and decreasing their off-task behavior. Implications of the study for research and practice are discussed. 相似文献

The use of multi-method, multi-informant assessment is a hallmark of research in child development and mental health; however,
many research strategies such as population surveys require brief assessment tools. The Alabama Parenting Questionnaire (APQ)
is a popular measure of empirically identified aspects of positive and negative parenting styles important to conduct problems
in children. A brief version exists, however it does not measure all relevant parenting domains, and it has not been validated
for child reports. We evaluated validity of the brief parent and child report version of the complete five subscale version
of the APQ in a sample of 208 children aged between 9 and 17, at risk for conduct problems and antisocial behaviour. The results
showed that all five dimensions of parenting can be measured using a brief 15 item version; specifically child and parent
reports converged as expected and discriminated high from low conduct problem children using parent and teacher reports. Only
child reports converged with independent observations of parenting behaviour, supporting previous research showing that child
reports of parenting are particularly important. Finally, results did not support the typical methods used for combining child
and parent reports into one index. 相似文献

BackgroundThe pharmacology of traumatic memory extinction has not been fully characterized despite its potential as a therapeutic target for established, acquired anxiety disorders, including post-traumatic stress disorder (PTSD). Here we examine the role of endogenous glucocorticoids in traumatic memory extinction.MethodsMale C57BL/6J mice were injected with corticosterone (10 mg/kg, i.p.) or metyrapone (50 mg/kg, s.c.) during re-activation of a contextual fear memory, and compared to vehicle groups (N = 10–12 per group). To ensure that metyrapone was blocking corticosterone synthesis, we measured corticosterone levels following re-activation of a fear memory in metyrapone- and vehicle-treated animals.ResultsCorticosterone administration following extinction trials caused a long-lasting inhibition of the original fear memory trace. In contrast, blockade of corticosteroid synthesis with metyrapone prior to extinction trials enhanced retrieval and prevented extinction of context-dependent fear responses in mice. Further behavioral analysis suggested that the metyrapone enhancement of retrieval and prevention of extinction were not due to non-specific alterations in locomotor or anxiety-like behavior. In addition, the inhibition of extinction by metyrapone was rescued by exogenous administration of corticosterone following extinction trials. Finally, we confirmed that the rise in corticosterone during re-activation of a contextual fear memory was blocked by metyrapone.ConclusionsWe demonstrate that extinction of a classical contextual fear memory is dependent on endogenous glucocorticoid synthesis during re-activation of a fear memory. Our data suggest that decreased glucocorticoids during fear memory re-activation may contribute to the inability to extinguish a fear memory, thus contributing to one of the core symptoms of PTSD. 相似文献

The positive youth development (PYD) perspective emphasizes that thriving occurs when individual ?context relations involve the alignment of adolescent strengths with the resources in their contexts. The authors propose that a key component of this relational process is the strength that youth possess in the form of self-regulatory processes; these processes optimize opportunities to obtain ecological resources that enhance the probability of PYD. They use the selection, optimization, and compensation (SOC) model of intentional self-regulation to discuss the role of self-regulation in the PYD perspective among diverse youth. 相似文献

The influence of athletic experience and kinematic information on skill-relevant affordance perception 总被引:1,自引:0,他引:1

Humans can perceive affordances both for themselves and for others, and affordance perception is a function of perceptual-motor experience involved in playing a sport. Two experiments investigated the enhanced affordance perception of athletes. In Experiment 1, basketball players and nonbasketball players provided perceptual reports for sports-relevant (maximum standing-reach and reach-with-jump heights) and non-sports-relevant (maximum sitting height) affordances for self and other. Basketball players were more accurate at perceiving maximum reach-with-jump for another person than were nonbasketball players, but were no better at perceiving maximum reach or sitting heights. Experiment 2 investigated the informational basis for this enhanced perceptual ability of basketball players by evaluating whether kinematics inform perceivers about action-scaled (e.g., force-production dependent), but not body-scaled (i.e., geometrically determined), affordances for others, and whether basketball experience enhances sensitivity to kinematic information. Only basketball players improved at perceiving an action-scaled affordance (maximum reach-with-jump), but not body-scaled affordances (maximum standing-reach and sit) with exposure to kinematic information, suggesting that action-scaled affordances may be specified by kinematic information to which athletes are already attuned by virtue of their sport experience. 相似文献

In recent decades, what matters for individual quality of life (QoL) has increasingly been the focus of empirical social science
research. However, individuals are rarely asked directly what is important for their quality of life as part of large-scale
surveys. The present analysis studies perceptions of what matters for QoL in a large-scale longitudinal dataset—the British
Household Panel Survey—which includes an open-ended question on QoL in three waves spanning ten years. We find that concepts
of QoL change over the life course and differ between men and women. We hypothesize that changes in perceptions of QoL are
related to important life events, such as the birth of a first child and retirement. These life events constitute ’turning
points’ after which individuals often shift their priorities of what matters for their QoL. We further explore whether such
shifts in priorities are stable or disappear more than five years after the life event. 相似文献

Two individuals acting together to achieve a shared goal often have an emergent set of afforded behavioral possibilities that may not easily reduce to either acting alone. In a series of experiments we examined the critical boundaries for transitions in behavior for individuals walking through an aperture alone or alongside another actor as a dyad. Results from experiment 1 indicated that an intrinsically scaled critical boundary for behavioral transitions was different in individuals than in dyads performing a similar task. Experiment 2 demonstrated that observers are perceptually sensitive to the difference in action parameters for the dyad, while still maintaining perceptual sensitivity about the boundaries of action relative to individuals. In experiment 3, we determined that observers' perception of critical action boundaries for individuals and dyads has a similar informational basis (eye-height scaling). In experiment 4, we demonstrated that observers were able to perceive critical action boundaries for other dyads independently of membership. Together, these results suggest that individuals are sensitive to the affordances related to a joint action, and that this process may not entirely reduce to the perception of the affordances for each individual. 相似文献

Psychotherapists often experience stress while providing psychotherapy, in particular when working with difficult presentations such as suicidality. As part of a larger study on the treatment of recently suicidal college students with borderline traits, 6 therapists in training collected their own salivary samples for alpha-amylase (AA) and cortisol (C) analyses immediately before and after sessions with 2 selected clients. On average, samples were collected for the same therapist-patient dyad throughout the year-long study to ensure that data reflected therapist responses across stages of treatment. Therapists also completed a working alliance questionnaire and rated perceived session difficulty immediately after each selected session. Contrary to expectations, therapists demonstrated elevated levels of stress as measured by AA and C at presession relative to postsession levels. Greater session difficulty was related to more pronounced declines in AA, whereas a stronger working alliance was linked to more pronounced reductions in C. Results suggest that physiological stress responses while working with recently suicidal clients with borderline traits occur primarily in terms of session anticipatory anxiety, whereas AA and C changes may be affected differently by factors such as session difficulty and working alliance. This is a pilot study, limited by its sample size, but the design, findings, and inclusion of physiological measures present an initial step in an essential line of research. 相似文献
