Perceived control and emotions: interactive effects on performance in achievement settings

Individual differences in cognitions and emotions play a critical role in difficult academic situations, such as the transition into college, a period infused with uncertainty. Perceived academic control (low vs. high) and emotions (course boredom, anxiety, and enjoyment) were examined to determine how they jointly predicted 620 first-year students’ achievement and attrition over an entire academic year. It was expected that students’ emotions would moderate the effects of high perceived control on achievement (final psychology grade, cumulative GPA) and attrition (overall course credits dropped). Regression results revealed several Perceived Control  ×  Emotion interactions that supported this moderation hypothesis: negative emotions impeded the benefits of high control (i.e., boredom and anxiety predicted worse performance in high-control students); positive emotions enhanced the benefits of high control (i.e., enjoyment predicted better performance in high-control students). Conversely, achievement emotions did not predict performance among low-control students. Together, these findings indicate that for a high level of perceived control to enhance students’ academic achievement and inhibit attrition, “adaptive” levels of emotions (lower boredom, lower anxiety, or higher enjoyment) are required. Implications for maximizing academic success among both low- and high-control students are discussed.

EMuJoy: Software for continuous measurement of perceived emotions in music

An adequate study of emotions in music and film should be based on the real-time measurement of selfreported data using a continuous-response method. The recording system discussed in this article reflects two important aspects of such research: First, for a better comparison of results, experimental and technical standards for continuous measurement should be taken into account, and second, the recording system should be open to the inclusion of multimodal stimuli. In light of these two considerations, our article addresses four basic principles of the continuous measurement of emotions: (1) the dimensionality of the emotion space, (2) data acquisition (e.g., the synchronization of media and the self-reported data), (3) interface construction for emotional responses, and (4) the use of multiple stimulus modalities. Researcher-developed software (EMuJoy) is presented as a freeware solution for the continuous measurement of responses to different media, along with empirical data from the self-reports of 38 subjects listening to emotional music and viewing affective pictures.

The Institute for Music Physiology and Musicians’ Medicine

The Institute of Music Physiology and Musicians' Medicine of the University of Music and Drama in Hannover, Germany, is a unique Institution in Europe whose scope includes teaching the basics of music physiology and musicians' medicine and research into the physiological and neurobiological principles of professional music performance and music perception. Furthermore, the institute conducts research into the causes of occupational injuries in musicians and provides means for prevention, diagnosis and treatment of such injuries.     

Truth in Applicative Theories

We give a survey on truth theories for applicative theories. It comprises Frege structures, universes for Frege structures, and a theory of supervaluation. We present the proof-theoretic results for these theories and show their syntactical expressive power. In particular, we present as a novelty a syntactical interpretation of ID₁ in a applicative truth theory based on supervaluation.     

Vibration-Induced Kinesthetic Illusions and Corticospinal Excitability Changes

The authors' aim was to investigate the changes of corticospinal excitability during kinesthetic illusions induced by tendon vibration. Motor-evoked potentials in response to transcranial magnetic stimulation were recorded from the vibrated flexor carpi radialis and its antagonist, extensor carpi radialis. The illusions were evoked under vision conditions without feedback for the position of the wrist (open or closed eyes). In these two conditions motor-evoked potential changes during vibration in the antagonist were not identical. This discrepancy may be a result of 2 simultaneously acting, different and opposite influences and the balance between them depends on visual conditions. Thus, the illusion was accompanied by the facilitation of corticospinal excitability in both vibrated muscle and its antagonist.     

How to Increase Vaccination Acceptance Among Apostolic Communities: Quantitative Results from an Assessment in Three Provinces in Zimbabwe

A worldwide increasing trend toward vaccine hesitancy has been reported. Measles outbreaks in southern Africa in 2009–2010 were linked to objections originating from Apostolic gatherings. Founded in Zimbabwe in the 1950s, the Apostolic church has built up a large number of followers with an estimated 3.5 million in Zimbabwe in 2014. To inform planning of interventions for the 2015 measles–rubella vaccination campaign, we assessed vaccination status and knowledge, attitudes and practices among purposive samples of Apostolic caregivers in three districts each in Harare City, Manicaland and Matabeleland South in Zimbabwe. We conducted structured interviews among 97 caregivers of children aged 9–59 months and collected vaccination status for 126 children. Main Apostolic affiliations were Johanne Marange (53%), Madida (13%) and Gospel of God (11%) with considerable variation across assessment areas. The assessment also showed considerable variation among Apostolic communities in children ever vaccinated (14–100%) and retention of immunization cards (0–83%) of ever vaccinated. Overall retention of immunization cards (12%) and documented vaccination status by card (fully vaccinated = 6%) were low compared to previously reported measures in the general population. Mothers living in monogamous relationships reported over 90% of all DTP-HepB-Hib-3, measles and up to date immunizations during the first life year documented by immunization card. Results revealed opportunities to educate about immunization during utilization of health services other than vaccinations, desire to receive information about vaccinations from health personnel, and willingness to accept vaccinations when offered outside of regular services. Based on the results of the assessment, specific targeted interventions were implemented during the vaccination campaign, including an increased number of advocacy activities by district authorities. Also, health workers offered ways and timing to vaccinate children that catered to the specific situation of Apostolic caregivers, including flexible service provision after hours and outside of health facilities, meeting locations chosen by caregivers, using mobile phones to set up meeting locations, and documentation of vaccination in health facilities if home-based records posed a risk for caregivers. Coverage survey results indicate that considerable progress has been made since 2010 to increase vaccination acceptability among Apostolic communities in Zimbabwe. Further efforts will be needed to vaccinate all Apostolic children during routine and campaign activities in the country, and the results from our assessment can contribute toward this goal.     

ERP correlates of auditory negative priming

Negative priming refers to slowed down reactions when the distractor on one trial becomes the target on the next. Following two popular accounts, the effect might be due either to inhibitory processes associated with the frontal cortex, or to an ambiguity in the retrieval of episodic information. We used event-related brain potentials (ERPs) to identify the processing stage primarily associated with negative priming. In an auditory categorization task, reactions in negative priming trials were compared to reactions in a standard control (unrelated primes and probes) and a repetition control (attended prime=ignored probe) condition. Reactions were slower for negative priming than for standard control (Delta32 ms) and repetition control trials (Delta64 ms). The corresponding ERP effect was reflected in an attenuation of a sustained parietal positivity extending from 300 to 600 ms. Because corresponding ERP components were found to be sensitive to stimulus recognition and familiarity, the results may be interpreted to support an episodic retrieval account of negative priming.
