Finding faults: analogical comparison supports spatial concept learning in geoscience

A central issue in education is how to support the spatial thinking involved in learning science, technology, engineering, and mathematics (STEM). We investigated whether and how the cognitive process of analogical comparison supports learning of a basic spatial concept in geoscience, fault. Because of the high variability in the appearance of faults, it may be difficult for students to learn the category-relevant spatial structure. There is abundant evidence that comparing analogous examples can help students gain insight into important category-defining features (Gentner in Cogn Sci 34(5):752–775, 2010). Further, comparing high-similarity pairs can be especially effective at revealing key differences (Sagi et al. 2012). Across three experiments, we tested whether comparison of visually similar contrasting examples would help students learn the fault concept. Our main findings were that participants performed better at identifying faults when they (1) compared contrasting (fault/no fault) cases versus viewing each case separately (Experiment 1), (2) compared similar as opposed to dissimilar contrasting cases early in learning (Experiment 2), and (3) viewed a contrasting pair of schematic block diagrams as opposed to a single block diagram of a fault as part of an instructional text (Experiment 3). These results suggest that comparison of visually similar contrasting cases helped distinguish category-relevant from category-irrelevant features for participants. When such comparisons occurred early in learning, participants were more likely to form an accurate conceptual representation. Thus, analogical comparison of images may provide one powerful way to enhance spatial learning in geoscience and other STEM disciplines.     

A look at how we look at others: Orientation inversion and photographic negation disrupt the perception of human bodies

Although disproportionate inversion effects have often been considered manifestations of the special processes recruited by upright faces, several papers using sequential matching tasks have reported that body postures also produce sizeable inversion effects. However, comparison of inversion effects observed with transient body postures and effects elicited by judgements of facial structure is complicated by qualitative differences between the stimuli and the tasks. Here we report a series of experiments that use attractiveness judgements to provide a better comparison of the effect of inversion as well as contrast negation on face and body perception. Significant effects of inversion and negation were observed for both face and body stimuli. While the magnitude of the inversion effects was broadly comparable, the negation effect was considerably larger for faces. These effects converge with evidence from cognitive neuroscience to suggest that both faces and bodies recruit similar orientation-specific processes distinct from processes used for generic objects.     

Going the distance: Extra-symbolic contributions to the symbolic control of spatial attention

Over the past 30 years, researchers have used symbolic cues such as spatial words and arrows to direct observers' attention to the location of target objects that appear at a single, fixed distance in simple visual environments; however, they have done so by using symbolic cues that provide only partial—directional—information about the spatial location of target objects. Thus, it remains unclear whether observers can only shift their attention broadly in the cued direction in response to these cues or whether they can shift their attention to the specific location of the target by combining an expectation about direction (derived from apprehension of the directional cue) with an expectation about distance (derived from some extra-symbolic cue). The results of two experiments showed that observers do shift their attention to relatively coarse spatial locations by combining expectancies about direction and distance, and that the extent to which observers do so is modulated by the presence of visible markers and the expected distance of the target. These findings are important because they provide the first evidence that extra-symbolic information about distance contributes to the symbolic control of spatial attention.     

How people think “if only …” about reasons for actions

When people think about how a situation might have turned out differently, they tend to imagine counterfactual alternatives to their actions. We report the results of three experiments which show that people imagine alternatives to actions differently when they know about a reason for the action. The first experiment (n = 36) compared reason – action sequences to cause – effect sequences. It showed that people do not imagine alternatives to reasons in the way they imagine alternatives to causes: they imagine an alternative to an action more than an effect, and to a cause more than a reason. The second experiment (n = 214) and the third experiment (n = 190) both show that different sorts of reasons have different sorts of effects on how people imagine alternatives to actions. People imagine an alternative to an action (the protagonist went to a ball) less often when they know the reason for the action was an obligation (he had to participate in fundraising) compared to when they know about a weaker reason (he wanted to meet a famous violinist) or no reason. The second experiment shows the effect for a social obligation and the third experiment replicates and extends it to a health obligation. We interpret the results in terms of the possibilities that people keep in mind about actions and their reasons.     

Participant recruitment methods and statistical reasoning performance

Optimal Bayesian reasoning performance has reportedly been elusive, and a variety of explanations have been suggested for this situation. In a series of experiments, it is demonstrated that these difficulties with replication can be accounted for by differences in participant-sampling methodologies. Specifically, the best performances are obtained with students from top-tier, national universities who were paid for their participation. Performance drops significantly as these conditions are altered regarding inducements (e.g., using unpaid participants) or participant source (e.g., using participants from a second-tier, regional university). Honours-programme undergraduates do better than regular undergraduates within the same university, paid participation creates superior performance, and top-tier university students do better than students from lower ranked universities. Pictorial representations (supplementing problem text) usually have a slight facilitative effect across these participant manipulations. These results indicate that studies should take account of these methodological details and focus more on relative levels of performance rather than absolute performance.     

The Transracial Adoption Debate: Counseling and Legal Implications

Over the last 30 years, the practice of White American parents adopting African American children has been the focus of much deliberation and commentary. In this article, the authors illuminate relevant literature and research regarding transracial adoption. Counseling and legal implications are also discussed.     

Social Support, Job Stress, Health, and Job Satisfaction Among Nurses in the United Kingdom

Recruitment and retention of nurses is a major concern in healthcare provision in several countries. This study explored the relationship between perceived social support, job stress, health, and job satisfaction among nurses from 4 organizations in northwest England. A total of 350 usable questionnaires measuring stressors, perceived support, health, and job satisfaction, was obtained from a sample of 1,162 nurses drawn from 4 healthcare organizations. A follow-up study was conducted after 6 months. Results indicate that perceived organizational support is related to nurses' health and job satisfaction. Current interventions to increase support, which typically operate at individual or group level, may be limited in their effectiveness unless nurses' perceptions of organizational support are taken into account.     

Preparing Rural Adolescents for Post‐High School Transitions

In this study, the authors evaluated the impact of 4 career development curricular strategies and emotional/instrumental support in preparing rural adolescents to make successful post‐high school transitions. Curriculum strategies and perceived support helped 8th‐, 10th‐, and 12th‐grade students attain critical aspects of career development, enhanced student satisfaction that their education was better preparing them to achieve future educational and career goals, and increased student intentions to enter post‐high school settings that required greater levels of education and training. Girls reported earning higher grades and participating in more work‐based learning activities and intended to enter post–high school training settings that required more education than did boys.     

Reasonable reasons for waiting

Recent decision‐making research claims to establish that, in violation of Savage's normative sure‐thing principle, individuals often wait to acquire noninstrumental information and subsequently base their decisions upon this information. The current research suggests that characterizing individuals as pursuing noninstrumental or useless information may be overstated. Through a series of experiments we establish, first, that many people choose to wait, even when waiting provides no additional information at all. Second, the longer people are allowed to wait before having to decide, the more people prefer to wait rather than decide immediately. Third, those individuals who choose to wait are the ones less confident about committing themselves to a decision. For them, the benefit from waiting may be especially valuable by allowing them to come to terms with a less‐than‐ideal decision. Copyright © 2003 John Wiley & Sons, Ltd.     

The prevention of depressive symptoms in rural Australian women

Two interventions aimed at preventing depressive symptoms in women living in Western Australian rural communities were evaluated against a no‐intervention control condition. The standard intervention was based upon traditional cognitive‐behaviour treatments for depression; the experimental intervention was based upon prevention strategies derived from the learned helplessness model of depression (e.g. Peterson, Maier, & Seligman, 1993 ). Seventy‐six women were randomly assigned to either the standard or the experimental group, and a further 20 women formed a no‐intervention control group. The standard group showed a reduction in depressive symptoms at post‐test, but no effects at 6‐week or 6‐month follow‐ups. In contrast, a reduction in depressive symptoms did not appear for the experimental group until the 6‐week follow‐up at which time a less depressive attributional style was also evident; these effects were even more pronounced at the 6‐month follow‐up. The no‐intervention control group showed no changes across time. It is argued that these results support the applicability of prevention strategies based on the learned helplessness model to this population. Copyright © 2003 John Wiley & Sons, Ltd.
