Any technique that conserves classroom instructional time without sacrificing the amount learned is of great educational value. This research compared a laboratory analogue of the clicker technique to analogues of other classroom pedagogical methods that all involve repeated testing during teaching. The clicker analogue mimics the classroom practice of dropping material that is understood by the majority of the class, as revealed by testing with clicker questions, from further lecture. A fact learning and retrieval paradigm was used, in which college students learned facts about unfamiliar countries. Compressing instruction time based on group-level performance produced as much learning as no compression and as compression based on individual-level performance. Results suggest that the clicker technique is an efficient and cost-effective method of conserving instructional time without loss of amount learned. 相似文献

What is the effect on memory when seemingly innocuous photos accompany false reports of the news? We asked people to read news headlines of world events, some of which were false. Half the headlines appeared with photographs that were tangentially related to the event; others were presented without photographs. People saw each headline only once, and indicated whether they remembered the event, knew about it, or neither. Photos led people to immediately and confidently remember false news events. Drawing on the Source Monitoring Framework (Johnson, Hashtroudi, & Lindsay, 1993), we suggest that people often relied on familiarity and other heuristic processes when making their judgments and thus experienced effects of the photos as evidence of memory for the headlines. 相似文献

Many White Americans are concerned about appearing prejudiced. How these concerns affect responses during actual interracial interactions, however, remains understudied. The present work examines stress responses to interracial contact-both in the moment, during interracial interactions (Study 1), and over time as individuals have repeated interracial contact (Study 2). Results of Study 1 revealed that concerns about appearing prejudiced were associated with heightened stress responses during interracial encounters (Study 1). White participants concerned about appearing prejudiced exhibited significant increases in cortisol "stress hormone" levels as well as increases in anxious behavior during interracial but not same-race contact. Participants relatively unconcerned about appearing prejudiced did not exhibit these stress responses. Study 2 examined stress responses to interracial contact over an entire academic year. Results revealed that White participants exhibited shifts in cortisol diurnal rhythms on days after interracial contact. Moreover, participants' cortisol rhythms across the academic year, from fall to spring, were related to their concerns about appearing prejudiced and their interracial contact experiences. Taken together, these data offer the first evidence that chronic concerns about appearing prejudiced are related to short- and longer-term stress responses to interracial contact. Implications for life in diverse spaces are discussed. 相似文献

Theory of mind requires belief‐ and desire‐understanding. Event‐related brain potential (ERP) research on belief‐ and desire‐reasoning in adults found mid‐frontal activations for both desires and beliefs, and selective right‐posterior activations only for beliefs. Developmentally, children understand desires before beliefs; thus, a critical question concerns whether neural specialization for belief‐reasoning exists in childhood or develops later. Neural activity was recorded as 7‐ and 8‐year‐olds (N = 18) performed the same diverse‐desires, diverse‐beliefs, and physical control tasks used in a previous adult ERP study. Like adults, mid‐frontal scalp activations were found for belief‐ and desire‐reasoning. Moreover, analyses using correct trials alone yielded selective right‐posterior activations for belief‐reasoning. Results suggest developmental links between increasingly accurate understanding of complex mental states and neural specialization supporting this understanding. 相似文献

Contemporary approaches for evaluating the demand for reinforcers use either the Exponential or the Exponentiated model of operant demand, both derived from the framework of Hursh and Silberberg (2008). This report summarizes the strengths and complications of this framework and proposes a novel implementation. This novel implementation incorporates earlier strengths and resolves existing shortcomings that are due to the use of a logarithmic scale for consumption. The Inverse Hyperbolic Sine (IHS) transformation is reviewed and evaluated as a replacement for the logarithmic scale in models of operant demand. Modeling consumption in the “log10-like” IHS scale reflects relative changes in consumption (as with a log scale) and accommodates a true zero bound (i.e., zero consumption values). The presence of a zero bound obviates the need for a separate span parameter (i.e., k) and the span of the model may be more simply defined by maximum demand at zero price (i.e., Q0). Further, this reformulated model serves to decouple the exponential rate constant (i.e., α) from variations in span, thus normalizing the rate constant to the span of consumption in IHS units and permitting comparisons when spans vary. This model, called the Zero-bounded Exponential (ZBE), is evaluated using simulated and real-world data. The direct reinstatement ZBE model showed strong correspondence with empirical indicators of demand and with a normalization of α (ZBEn) across empirical data that varied in reinforcing efficacy (dose, time to onset of peak effects). Future directions in demand curve analysis are discussed with recommendations for additional replication and exploration of scales beyond the logarithm when accommodating zero consumption data. 相似文献

The relationship between past body size and current body dissatisfaction among 933 middle-aged women from a prospective birth cohort study was examined. Women provided self-report data on weight esteem at age 54. Height and weight data were collected at ages 7, 11, 15, 20, 26, 36, 43, and 54. Data on reproductive variables were also collected prospectively. Hierarchical linear modeling and multiple regression analyses were used. Women who were dissatisfied at midlife were heavier at age 7 and showed a more rapid increase in body mass index with age. A late menarche, being postmenopausal, and having started hormone replacement therapy before menopause were associated with less dissatisfaction. Attention to these factors across the life span is necessary to understand body dissatisfaction in women at midlife. 相似文献

Movement to spatial targets that can, in principle, be carried out by more than one effector can be distinguished from movements that involve specific configurations of body parts. The experiments reported here investigate memory span for a series of hand configurations and memory span for a series of hand movements to spatial locations. Spans were produced normally, or in conditions in which a suppression task was carried out on the right or the left hand while the movements to be remembered were presented. All movements were recalled using the right hand. There were two suppression tasks. One involved repeatedly squeezing a tube and so changing the configuration of the hand, and the other involved tapping a repeated series of spatial targets. The spatial tapping task interfered with span for spatial locations when it was presented on either the right or the left hand but did not affect span for movement pattern. The movement suppression task interfered with memory for movement pattern when it was presented on either the right or the left hand, but did not interfere with span for spatial locations. It is concluded that memory for movement configurations involves different processes from those used in spatial tasks and that there may be a need for a subsystem of working memory that is specific for movement configuration. 相似文献

Primary care providers were surveyed to determine how prepared they feel to address nonsuicidal self‐injury (NSSI) among adolescents, their interest in training on NSSI, and factors associated with routinely asking about NSSI when providing health supervision. Participants included family medicine physicians (n = 260), pediatricians (n = 127), family nurse practitioners (n = 96), and pediatric nurse practitioners (n = 54). Almost 50% felt unprepared to address NSSI, and over 70% wanted training in this area. Overall, relative to other areas of mental health care, clinicians felt least prepared to address and wanted more training on NSSI. Just 27% reported they routinely inquired about NSSI during health supervision. Factors associated with routinely asking about NSSI were identifying as female (OR = 2.37; 95% CI = 1.25–4.49), feeling better prepared to address NSSI (OR = 1.51; 95% CI = 1.04–2.20), and more frequently using a psychosocial interview to identify adolescents in distress (OR = 1.23; 95% CI = 1.02–1.48). Teaching clinicians to assess NSSI within a psychosocial interview may increase screening for and identification of the behavior among adolescents in primary care. 相似文献
