Mental Juggling: When Does Multitasking Impair Reading Comprehension?

The present study investigated the conditions under which multitasking impairs reading comprehension. Participants read prose passages (the primary task), some of which required them to perform a secondary task. In Experiment 1, we compared two different types of secondary tasks (answering trivia questions and solving math problems). Reading comprehension was assessed using a multiple-choice test that measured both factual and conceptual knowledge. The results showed no observable detrimental effects associated with multitasking. In Experiment 2, the secondary task was a cognitive load task that required participants to remember a string of numbers while reading the passages. Performance on the reading comprehension test was lower in the cognitive load conditions relative to the no-load condition. The present study delineates the conditions under which multitasking can impair or have no effect on reading comprehension. These results further our understanding of our capacity to multitask and have practical implications in our technologically advanced society in which multitasking has become commonplace.     

Associations between type of treatment and illness-specific locus of control in type 1 diabetes patients

Abstract

This study examined differences in diabetes-specific locus of control beliefs of 82 insulin-treated Type I diabetes patients undergoing either conventional therapy (CT), intensified conventional therapy (ICT) or continuous subcutaneous insulin infusion (CSII). Compared to CT with its adherence to a strict regimen, ICT and CSII allow a much greater flexibility in timing of meals and daily activities. On the other hand, such flexibility requires a much more active role of the patient. The hypotheses of higher internality and lower powerful others locus of control beliefs in ICT and CSII patients than in CT patients could be supported for powerful others locus of control only. A one-year follow-up replicated this finding. Furthermore, high powerful others locus of control was associated with low diabetes-related knowledge and poor glycaemic control. The relevance of the patients' experience with the respective treatment is examined in view of the results and implications for studies on the feasibility of diabetes regimens are discussed.     

Ceci n'est pas la mort: Evidence for the recruitment of self‐reference from surrealistic art under mortality salience

Previous research has demonstrated that death reminders influence how we perceive art. In the context of terror management theory, this has been explained by the death‐transcending quality of art to convey cultural meaning. In two studies, we examined psychological and neurocognitive responses to naturalistic and surrealistic art when death was primed. We found that naturalistic paintings were evaluated similarly in terms of personal reassurance in both mortality salience and control condition, whereas surrealistic paintings were evaluated as more reassuring in the mortality salience condition than in the control condition. Using high‐field functional magnetic resonance imaging in a second study, we found a similar pattern of results, showing specific activation in the precuneus, a brain area associated with self‐related operations, in all prime conditions for the viewing of naturalistic paintings, but only in the death and disgust prime conditions when viewing surrealistic paintings. Our results suggest motivated self‐reference when viewing both naturalistic and surrealistic artworks under mortality salience. Copyright © 2014 John Wiley & Sons, Ltd.     

Religious identity and educational attainment among recent immigrants to Canada: Gender, age, and 2nd generation

Using data from Canadian decennial censuses, this article explores the relationship of religious identity and educational attainment among post-1970 immigrants to Canada and their Canadian-born offspring. Immigrants have higher levels of educational attainment than the Canadian average, but in the first generation men have higher levels than women in each religious category, and Sikhs and Buddhists are on average significantly less well educated. These differences diminish in the younger immigrants and disappear in the second generation. Here women are consistently better educated than men, and no religion stands out. Yet the high educational levels among immigrants do not correspond to income levels. Muslims are particularly disadvantaged in this regard.     

Control blindness: Why people can make incorrect inferences about the intentions of others

There is limited evidence regarding the accuracy of inferences about intention. The research described in this article shows how perceptual control theory (PCT) can provide a “ground truth” for these judgments. In a series of 3 studies, participants were asked to identify a person’s intention in a tracking task where the person’s true intention was to control the position of a knot connecting a pair of rubber bands. Most participants failed to correctly infer the person’s intention, instead inferring complex but nonexistent goals (such as “tracing out two kangaroos boxing”) based on the actions taken to keep the knot under control. Therefore, most of our participants experienced what we call “control blindness.” The effect persisted with many participants even when their awareness was successfully directed at the knot whose position was under control. Beyond exploring the control blindness phenomenon in the context of our studies, we discuss its implications for psychological research and public policy.     

PKG-mediated MAPK signaling is necessary for long-term operant memory in Aplysia

Signaling pathways necessary for memory formation, such as the mitogen-activated protein kinase (MAPK) pathway, appear highly conserved across species and paradigms. Learning that food is inedible (LFI) represents a robust form of associative, operant learning that induces short- (STM) and long-term memory (LTM) in Aplysia. We investigated the role of MAPK signaling in LFI memory in vivo. Inhibition of MAPK activation in animals prior to training blocked STM and LTM. Discontinuing MAPK signaling immediately after training inhibited LTM with no impact on STM. Therefore, MAPK signaling appears necessary early in memory formation for STM and LTM, with prolonged MAPK activity required for LTM. We found that LFI training significantly increased phospho-MAPK levels in the buccal ganglia. Increased MAPK activation was apparent immediately after training with greater than basal levels persisting for 2 h. We examined the mechanisms underlying training-induced MAPK activation and found that PKG activity was necessary for the prolonged phase of MAPK activation, but not for the early MAPK phase required for STM. Furthermore, we found that neither the immediate nor the prolonged phase of MAPK activation was dependent upon nitric oxide (NO) signaling, although expression of memory was dependent on NO as previously reported. These studies emphasize the role of MAPK and PKG in negatively reinforced operant memory and demonstrate a role for PKG-dependent MAPK signaling in invertebrate associative memory.     

Do salespeople matter in competitive tenders?

Abstract

Organizational buyers are increasingly employing competitive tenders with objective buying criteria to mitigate the influence of personal relationships with suppliers and reduce the overall cost of buying. This paper investigates the role of salespeople’s relationships with buyers (i.e., purchasing managers) and how they affect supplier selection in such contexts. Drawing on data from 428 tenders across different buying organizations, this study shows that the quality of the salesperson’s relationship with the buyer influences the buyer’s evaluation of the tender proposal, which, in turn, affects supplier selection. Thus, the results support an indirect effect of salesperson relationship on supplier selection even in a tender context. In addition, the results indicate that the effect of a salesperson’s relationship on buyer’s proposal evaluation is contingent on the comprehensibility of suppliers’ proposals and buyer’s product knowledge. These results have significant theoretical and managerial implications for both buyers and suppliers in business-to-business (B2B) tender contexts.     

Social relationships in the workplace

As more workers with disabilities are competitively employed, there are numerous opportunities to form social relationships with their co-workers. Close social relationships are associated with a number of positive outcomes (e.g., happiness, less stress) and should be actively pursued for those individuals desiring them. In this paper, we describe the types of social interactions displayed in work settings employing workers with and without disabilities. We also discuss some of the social problems experienced by some workers with disabilities. Finally, we describe two general categories of intervention strategies that have been used to impact social relationships: (a) strategies that involve changing the social behaviors of workers with disabilities, and (b) natural support strategies. The results from these strategies are discussed, and future areas of research are described. MRDD Research Reviews 7:128-133, 2001.     

„Psychopathy“ im Kindes- und Jugendalter

The term psychopathy is defined as a severe personality pathology, which is characterized by extreme aggressive, antisocial and violent behavior as well as affective and interpersonal deficits. In recent years, research into the construct of psychopathy has often focused on the incidence and detection of such pathologies in children and adolescents. In this context, a point of interest is to explore the course and stability of psychopathic personality dimensions throughout youth. Results demonstrate clear evidence for the occurrence of personality traits characteristic for psychopathy in early childhood and adulthood, which facilitates early detection with the aid of age-specific diagnostic instruments.The distinct correlation between psychopathy and severe, repeated and largely treatment refractory violence, which results in substantial public damage, calls for further research in children and adolescents in order to define the construct of psychopathy more precisely, to further illuminate underlying pathologies and consequently develop more specific typologies and effective treatment strategies. To that end, it is of particular importance to correctly capture dimensional factors of psychopathy in youth and to examine their stability throughout stages of adolescent development.     

Patient Autonomy and Quality of Care in Telehealthcare

Telemedicine is a complex field including various applications and target groups. Especially telehealthcare is seen by many as a means to revolutionize medicine. It gives patients the opportunity to take charge of their own health by using self-tracking devices and allows health professionals to treat patients from a distance. To some, this means an empowerment of patient autonomy as well as an improvement in the quality of care. Others state the dangers of depersonalization of medicine and the pathologization of daily life. This paper examines the ethical implications of telehealthcare, focusing on patient autonomy and quality of care by analyzing metareviews, randomized controlled trials and narrative ethical analyses on the topic. As a result, we conclude that the technically enhanced encounter between patients and health professionals may mean an empowerment of patient autonomy when it goes along with a personal relationship based on trust, assistance and support. When it comes to the quality of care, telehealthcare may lead to an improvement as long it is adopted to the patient’s individual needs.
