Despite decades of interest in moral character, comparatively little is known about moral behavior in everyday life. This paper reports a novel method for assessing everyday moral behaviors using the Electronically Activated Recorder (EAR)—a digital audio-recorder that intermittently samples snippets of ambient sounds from people’s environments—and examines the stability of these moral behaviors. In three samples (combined N = 186), participants wore an EAR over one or two weekends. Audio files were coded for everyday moral behaviors (e.g., showing sympathy, gratitude) and morally-neutral comparison language behaviors (e.g., use of prepositions, articles). Results indicate that stable individual differences in moral behavior can be systematically observed in daily life, and that their stability is comparable to the stability of neutral language behaviors.  相似文献

Since the inception of Counselling for Depression (CfD) in the UK as a competence-based training course for experienced therapists, there has been remarkably little empirical work exploring the experiences and views of trainees and those involved in course delivery.  相似文献

In Study 1, we evaluated preference stability across 4 preference‐assessment methods for 6 individuals, 5 of whom had autism spectrum disorder and 1 of whom had traumatic brain injury. We also measured participants’ problem behavior as a corollary measure during all assessment methods. The highest mean correlation coefficients and Kendall rank coefficients of concordance across administrations were observed for the paired‐stimulus and multiple‐stimulus‐without‐replacement methods. Lower correspondence across administrations was observed for the free‐operant and response‐restriction methods. Although differentially higher levels of problem behavior did not occur with a single method, lower levels were consistently observed with the free‐operant method. During Study 2, we evaluated the implications of lower coefficients on reinforcer efficacy by comparing an initially identified and an immediately identified high‐preference stimulus in a reinforcer assessment. Initially identified and immediately identified high‐preference stimuli were equally effective reinforcers, suggesting that fluctuations in preference do not necessarily affect reinforcer efficacy in practice.  相似文献

The Test for Creative Thinking—Drawing Production (TCT‐DP) is designed as an effective drawing‐based instrument for measuring creative potential. Many studies report adaptation efforts in other cultures pointing out good psychometric properties of the instrument nonetheless revealing also some trouble spots. The present study includes adaptation of TCT‐DP in Latvia and investigation of psychometric properties of the instrument such as measurement invariance between forms, sequence effect, gender differences, and factor structure of criteria employing methodology of structural equation modeling. Two samples were involved in the study—9th‐grade students (n = 300) and 15‐year‐old 9th‐grade students (n = 200). Results indicate that trained judges are able to achieve high reliability in evaluation of TCT‐DP total score and all criteria if some criteria are divided into subcategories. It was also found that TCT‐DP has measurement invariance between both forms but has small effect sizes regarding gender differences and method sequence. Observed differences of TCT‐DP total scores between the Latvian sample and relevant samples from Germany and Hong Kong could be considered as trivial. The study also revealed that, following original instructions, some test criteria had strong interdependence and therefore strategies in the evaluation process reducing interdependencies between criteria should be considered in future studies on the structure of TCT‐DP.  相似文献

The parallels between cognitive development and creativity are neglected in the literature. Piaget's information transformations are personalized, meaning individual constructions can involve creativity. Vygotsky's work considers the implications and interactions of social influences, conventions, and personal implications for creative development. The Cognitive‐Creative Sifting Model is proposed to focus attention on these and other connections between cognitive development and creativity. Other common methods of assessing creativity are compared to the proposed model. It is argued that the model provides a foundation to evaluate individual creative potentials more holistically. Specifically, the conceptual elements of metacognition are described and their role in the development of creativity is suggested. It is argued that future researchers should pay particular attention to the interaction effects metacognition has with traditional measures of creativity focused on ideation and product evaluation.  相似文献

The current study concerns the validation of an English version of the German Test Anxiety Inventory, namely the PAF-E. This questionnaire is a multi-faceted measure of test anxiety designed to detect normative test anxiety levels and in consequence meet the need of consultancy. Construct and criterion validity of (PAF-E) were examined with a sample of 96 secondary students (Mage = 12.8, SD = 0.67; 55% girls) from an international school in Berlin (Germany) and 399 secondary students (Mage = 13.4, SD = 0.80; 56% girls) from Montréal (Canada). Both samples completed the PAF-E and related constructs, such as school-related self-efficacy, inhibitory test anxiety, achievement motivation, and the Big Five. Exploratory and confirmatory factor analyses confirmed the four-factor-structure (worry, emotionality, interfering thoughts, lack of confidence) of the original German Test Anxiety Inventory (PAF). Each subscale consists of five items with a total of 20 questions. Cronbach's alpha, ranging from.71 to.82 among Germans and.77 to.87 among Canadians as well as the re-test reliability (from.80 to.85 among Canadians) were sufficient. The differential patterns of correlations between other constructs and the indices of test anxiety indicate good construct validity.  相似文献

This study presents a protocol for induction of moderate psychosocial stress and investigates its impact on psychological and physiological responses. The proposed procedure was designed to enable researchers to assess cognitive performance under effect of various classes of stressors. The protocol's structure contains three main periods: baseline, assessment, and recovery. The assessment stage starts with task anticipation, during which audience (three-member commission) is introduced and apparatus (cameras, microphones, lights, and physiological measuring devices) stationed. Subsequently, cognitive performance was tested. The protocol was evaluated on 56 university students that were randomly assigned to control or stress (protocol) treatment and administered three cognitive tests (working memory operation span, remote associates test, and semantic fluency). Compared to control sessions, protocol induced state anxiety, interfering worry thoughts, and disturbance during recovery period. In addition, the stress group also showed elevated levels of skin conductance, higher average heart rates, and larger drops in peripheral temperature. Even though more research is needed, these results suggest that the protocol effectively induces both psychological and physiological stress responses and therefore encourages utilization in cognitive-affective and cognitive-biological fields of research.  相似文献

This rejoinder, in response to the commentaries of Steiner, Park, and Kim (this issue) and Reshetnyak, Cham, and Hughes (this issue), discusses remaining challenges in grade retention research. First, a same-age comparison assumes that the instruments used in different grades measure ability equally well. We discuss the importance of evaluating the properties of the scaling process to address whether this assumption has been met. Second, we discuss issues in the selection of covariates to be included in the weights. Third, we discuss the unconfoundedness assumption and the problem of remaining imbalance. Finally, we provide an empirical illustration showing that studying grade-retention effectiveness comes with multiple methodological decisions that are rooted in a bias–variance trade-off.  相似文献

This article was originally read as an introductory plenary paper at the German-Nordic Clinical Conference, September 2015 in Berlin. The heading of the conference was ‘On Cruelty and Destructiveness’. The paper takes as its starting point the composite figure of Dr Jekyll and Mr Hyde. It discusses the meaning of intentionality, or the lack of a conscious intention of being evil, in comparison to evil deeds caused by uninhibited drive satisfaction. Evilness is put into a social and a psycho-developmental context. Examples of contemporary atrocities are discussed, leading up to a formulation of a multi-factorial explanatory model of evil, taken from Michael Stones book ‘The Anatomy of Evil’.  相似文献
