Self-efficacy dimensions and job search strategies

ObjectiveThis study explored the paths between dimensions of self-efficacy and job search strategies. An examination of social cognitive career theory and career adaptability enabled us to consider several paths between dimensions of self-efficacy and job search strategies, as well as among self-efficacy dimensions.MethodScales measuring these concepts were administered to a sample of 120 jobseekers.ResultsStructural analyses allowed us to confirm expected paths. Barrier coping efficacy is significantly related to career decision self-efficacy. Career decision self-efficacy and job search self-efficacy are related to exploratory strategy and to job search strategy.ConclusionResults are discussed with reference to the literature and in terms of practical implications. They highlight the need to implement interventions in order to increase barrier coping efficacy and career decision self-efficacy.     

What Makes an Idea Risky? The Relations between Perceptions of Idea Novelty,Usefulness, and Risk

Individuals and organizations frequently tout creative ideas as a desirable goal, and yet, creative ideas are frequently rejected. Creativity researchers have often suggested that creative ideas are rejected because they are perceived as riskier due to their inherent novelty or originality. Although this assumption is prevalent, we are unaware of any empirical research directly examining the relations between perceptions of novelty and risk. We provide an empirical test of this assumption in two studies in which participants rate the novelty, usefulness, and riskiness of ideas. Across both studies, we find consistent support for the idea that usefulness, rather than novelty, has the strongest relation with risk perceptions. We also find some evidence that novelty and usefulness interact to predict perceptions of risk. Additionally, in Study 2, we find that usefulness has the strongest relation with willingness to invest and buy a product. The findings of this study suggest that the bias against creativity may be driven by the perceived usefulness of an idea, rather than its novelty, such that ideas with lower usefulness are perceived to be riskier.     

To what extent does typicality boost semantic priming effects between members of their categories?

Atypical items of their semantic category yield more generalisation than their typical members when relearning in connectionist networks (Plaut, D. C. (1996). Relearning after damage in connectionist networks: toward a theory of rehabilitation. Brain and Language, 52(1), 25–82) and in empirical studies (Kiran, S., & Thompson, C. K. (2003). The role of semantic complexity in treatment of naming deficits: Training semantic categories in fluent aphasia by controlling exemplar typicality. Journal of Speech, Language, and Hearing Research, 46(4), 773–787). It seems therefore that atypical words provide more information about the overall structure of the semantic category due to their specific and shared features. In this view, atypical primes could strongly facilitate the processing of targets compared to typical primes, because typical primes contain little information about the variation between members within a category. In contrast, three semantic priming experiments in visual word recognition showed an advantage with the typical context, but not with the atypical one. These findings were observed in a variety of tasks, including lexical decision, categorisation and semantic judgment. Our results do not support the findings about generalisation in relearning and suggest that typicality effects in semantic priming mostly come from the activation of representative features of categories.     

Divided attention between lyrics and tunes of operatic songs: Evidence for independent processing

Excerpts from French operatic songs were used to evaluate the extent to which language and music compete for processing resources. Do these two dimensions conflict? Are they integrated into a single percept? Or are they independent? The final word of each excerpt was either semantically congruous or incongruous relative to the prior linguistic context and was sung either in or out of key. Participants were asked to detect either the semantic or the melodic incongruity (single task) or both (dual task). We predicted a dual-task deficit if these tasks conflicted and no deficit if they were either independent or integrated. In order to distinguish between these last two outcomes, trial-by-trial contingency analyses were also computed, predicting no correlation if the tasks were conflicting or independent, a positive correlation under the assumption of integration and a negative correlation if dividing attention is impossible. Our results show similar levels of performance in single and dual tasks and no correlation between dual-task judgments, thus suggesting that semantic and melodic aspects of language are processed by independent systems. In addition, a comparison between musicians and nonmusicians shows that these conclusions are independent of musical expertise.     

A League of Their Own: Do Single-Sex Schools Increase Girls�� Participation in the Physical Sciences?

With the rapid shifts in the education of women in the United States, and the underrepresentation of women in fields of science, technology, engineering, and math (STEM), an issue generating much controversy is whether women may benefit more from single-sex education or coeducation. The present study surveyed 548 U.S. high-school boys and girls from single-sex and coeducational high-schools from the Midwest. Half of the participants completed a mathematics test under stereotype threat (ST) condition and half under no threat condition. Although girls in single-sex schools had higher achievement motive and self-esteem than those in coeducational schools, they were not more likely to pursue STEM careers. Overall, students in single-sex schools outperformed students from coeducational schools on the math test. Girls?? math performance was significantly higher in the ST condition than in the no threat condition.     

The involvement of epigenetic defects in mental retardation

Mental retardation is a group of cognitive disorders with a significant worldwide prevalence rate. This high rate, together with the considerable familial and societal burden resulting from these disorders, makes it an important focus for prevention and intervention. While the diseases associated with mental retardation are diverse, a significant number are linked with disruptions in epigenetic mechanisms, mainly due to loss-of-function mutations in genes that are key components of the epigenetic machinery. Additionally, several disorders classed as imprinting syndromes are associated with mental retardation. This review will discuss the epigenetic abnormalities associated with mental retardation, and will highlight their importance for diagnosis, treatment, and prevention of these disorders.     

Bodily excellence and education: ambiguities of performance

The notion of excellence contains an ambivalence: to aim at the "good" and/or to aim at the "best". This ambivalence exists particularly in the physical effort and in the history of bodily practices, shared between gymnastics, physical education and sports. In the second part of the XXth century, the notion of performance became "worship of performance", "infinite perfectibility". In this context, high level sports became the human improvement laboratory, thanks to the sophistication of its technical means and the its practices intensity. However this "high" questions: about physical and psychological consequences of intensive practices ; about doping and its medical and ethical perspectives; about the increasing precociousness and the potential exploitation of the baby champions. It questions about the nature of familial, social, economical norms transmitted by education: about articulation between constraint and self-government. This is the question about the "price" of excellence. In this sense it appears that the excellence of champion spreads out the margins of an ethics which would be meant to be regulating and universal, indeed this excellence is perhaps, in the same capacity as genius is and in spite of the attachment of sports to a "ethics of the rule", un-ethical.     

Are imaging and lesioning convergent methods for assessing functional specialisation?: investigations using an artificial neural network

This article presents an investigation of the relationship between lesioning and neuroimaging methods of assessing functional specialisation, using synthetic brain imaging (SBI) and lesioning of a connectionist network of past-tense formation. The model comprised two processing ‘routes’: one was a direct route between layers of input and output units, while the other, indirect, route featured an intermediate layer of processing units. Emergent specialisation within the network was assessed (1) by lesioning either the direct or indirect route and measuring past-tense performance for regular and irregular verbs, and (2) by measuring functional activation in each route when processing each verb type (SBI). SBI and lesioning approaches failed to converge when network activation was summed over each route in our SBI approach. Examination of individual network solutions suggested that the verb types might be using the indirect route differently in terms of the pattern of activation across the route, rather than in terms of gross activation. A subsequent SBI analysis compared patterns of activation in the indirect route and confirmed that these patterns were more similar between regular-type verbs than between regular and irregular verbs. As the spatial and temporal resolution of neuroimaging techniques improves, the results of this investigation suggest that the key to finding functional specialisation will be to distinguish local coding differences across behaviours that are the results of developmental processes. Other analyses suggest that lesioning data may be limited because, with increasing damage, they reveal the resting activations of a computational system rather than a computational specialisation per se.     

Expressiveness in musical emotions

This study was designed to investigate how emotion category, characterized by distinct musical structures (happiness, sadness, threat) and expressiveness (mechanical, expressive) may influence overt and covert behavioral judgments and physiological responses in musically trained and untrained listeners. Mechanical and expressive versions of happy, sad and scary excerpts were presented while physiological measures were recorded. Participants rated the intensity of the emotion they felt. In addition, they monitored excerpts for the presence of brief breaths. Results showed that the emotion categories were rated higher in the expressive than in the mechanical versions and that this effect was larger in musicians. Moreover, expressive excerpts were found to increase skin conductance level more than the mechanical ones, independently of their arousal value, and to slow down response times in the breath detection task relative to the mechanical versions, suggesting enhanced capture of attention by expressiveness. Altogether, the results support the key role of the performer’s expression in the listener’s emotional response to music.
