Judging the plausibility of arguments in scientific texts: a student–scientist comparison

The ability to evaluate scientific claims and evidence is an important aspect of scientific literacy and requires various epistemic competences. Readers spontaneously validate presented information against their knowledge and beliefs but differ in their ability to strategically evaluate the soundness of informal arguments. The present research investigated how students of psychology, compared to scientists working in psychology, evaluate informal arguments. Using a think-aloud procedure, we identified the specific strategies students and scientists apply when judging the plausibility of arguments and classifying common argumentation fallacies. Results indicate that students, compared to scientists, have difficulties forming these judgements and base them on intuition and opinion rather than the internal consistency of arguments. Our findings are discussed using the mental model theory framework. Although introductory students validate scientific information against their knowledge and beliefs, their judgements are often erroneous, in part because their use of strategy is immature. Implications for systematic trainings of epistemic competences are discussed.     

Pinning down attributions: the linguistic category model applied to wrestling reports

Implicit attributions in media coverage of wrestling events are investigated. A special feature of show wrestling is a separation in morally good fighters who win because of their intrinsic goodness and morally bad fighters who win by bending the rules. Thus, show wrestling can be characterized by the attributions it affords. Linguistic abstractness as an index of attributions of dispositionality is measured with the Linguistic Category Model (LCM; Semin & Fiedler, 1988). Analyses of published fight reports in an official wrestling magazine show that goodness and badness is indeed attributed on a stable and global level and that fights with the expected outcome are described in terms of fighters' dispositions in contrast to fights with an unexpected outcome.

Teachers’ perceived time pressure,emotional exhaustion and the role of social support from the school principal

Social Psychology of Education - Many teachers experience high levels of work-related strain due to time pressure, which over time can lead to various health problems, such as emotional exhaustion....     

Low Working Memory rather than ADHD Symptoms Predicts Poor Academic Achievement in School-Aged Children

This study examined whether working memory (WM), inattentive symptoms, and/or hyperactive/impulsive symptoms significantly contributed to academic, behavioral, and global functioning in 8-year-old children. One-hundred-sixty 8-year-old children (75.6% male), who were originally recruited as preschoolers, completed subtests from the Wechsler Intelligence Scale for Children–Fourth Edition, Integrated and Wechsler Individual Achievement Test–Second Edition to assess WM and academic achievement, respectively. Teachers rated children’s academic and behavioral functioning using the Vanderbilt Rating Scale. Global functioning, as rated by clinicians, was assessed by the Children’s Global Assessment Scale. Multiple linear regressions were completed to determine the extent to which WM (auditory-verbal and visual-spatial) and/or inattentive and hyperactive/impulsive symptom severity significantly contributed to academic, behavioral, and/or global functioning. Both auditory-verbal and visual-spatial WM but not ADHD symptom severity, significantly and independently contributed to measures of academic achievement (all p < 0.01). In contrast, both WM and inattention symptoms (p < 0.01), but not hyperactivity-impulsivity (p > 0.05) significantly contributed to teacher-ratings of academic functioning. Further, inattention and hyperactivity/impulsivity (p < 0.04), but not WM (p > 0.10) were significantly associated with teacher-ratings of behavioral functioning and clinician-ratings of global functioning. Taken together, it appears that WM in children may be uniquely related to academic skills, but not necessarily to overall behavioral functioning.     

The impact of implicitly and explicitly primed ingroup–outgroup categorization on the evaluation of others pain: The case of the Jewish–Arab conflict

Despite the automaticity of affective sharing, many studies have documented the role of top-down effects, such as social categorization, on people’s empathic responses. An important question, largely ignored in previous research, concerns empathy to ingroup and outgroup members’ pain in the contexts of ongoing intergroup conflict. In the present study we examined how implicit and explicit ethnic social categorization of others affects empathy to pain in the context of the Israeli–Palestinian conflict. To meet this aim, we assessed the evaluation of pain by Jewish and Arab participants who viewed a series of visual stimuli depicting painful and non-painful familiar situations. The stimuli were associated with explicitly or implicitly primed typical names depicting ingroup, neutral outgroup, and adversary outgroup members. Results demonstrate that pain ratings in the explicit priming condition provide support for the ingroup empathy hypothesis, positing that empathy is higher for ingroup than for outgroup members for both Jews and Palestinian Arabs. Conversely, when the targets’ categories are primed implicitly, results revealed difference in empathy by the two ethnic groups where an ingroup bias was detected only for Palestinian Arabs. This suggests that the activation of ingroup bias on the subliminal implicit level among Palestinian Arab participants might be mediated by the amount of conflict permeating in their daily lives and by deeply rooted cultural values and behavioural patterns.     

Muslims Love Jesus,Too? Corrective Information Alters Prejudices Against Islam

The present study examined whether prejudices towards Islam can be altered through corrective information. A total of 1715 German participants were first asked to appraise their opinions towards Judaism, Christianity and Islam (the ratings pertained to progressiveness, tolerance, peacefulness). Subsequently, questions regarding knowledge about religious topics were posed to participants. Questions were selected to elicit common prejudices pertaining to Islam. The correct answers were then displayed along with detailed explanations. Finally, participants were asked to rate their current opinion towards the three religions once again. Opinions towards Islam were largely negative at baseline but improved significantly after presentation of the correct answers. The present study suggests that prejudices against Islam are partially fueled by knowledge gaps.     

Social learning modulates the lateralization of emotional valence

Although neuropsychological studies of lateralization of emotion have emphasized valence (positive vs. negative) or type (basic vs. complex) dimensions, the interaction between the two dimensions has yet to be elucidated. The purpose of the current study was to test the hypothesis that recognition of basic emotions is processed preferentially by the right prefrontal cortex (PFC), whereas recognition of complex social emotions is processed preferentially by the left PFC. Experiment 1 assessed the ability of healthy controls and patients with right and left PFC lesions to recognize basic and complex emotions. Experiment 2 modeled the patient’s data of Experiment 1 on healthy participants under lateralized displays of the emotional stimuli. Both experiments support the Type as well as the Valence Hypotheses. However, our findings indicate that the Valence Hypothesis holds for basic but less so for complex emotions. It is suggested that, since social learning overrules the basic preference of valence in the hemispheres, the processing of complex emotions in the hemispheres is less affected by valence.     

Effects of scenery, lighting, glideslope, and experience on timing the landing flare

This study examined three visual strategies for timing the initiation of the landing flare based on perceptions of either: (a) a critical height above ground level; (b) a critical runway width angle (Psi); or (c) a critical time-to-contact (TTC) with the runway. Visual displays simulated landing approaches with trial-to-trial variations in glideslope, lighting, and scene detail. Twenty-four participants (8 private pilots, 8 student pilots, and 8 nonpilots) were instructed to initiate the flare when they perceived that their TTC with the runway (30 m wide by 840 m long) had reached a critical value of 2 seconds. Our results demonstrated a significant effect of flight experience on flare timing accuracy and dominance of the height-based strategy over the runway-width-angle and TTC-based strategies.
