Autonomy, competence, and social relatedness in task interest within project-based education

To prepare students for instructive collaboration, it is necessary to have insight into students' psychological needs and interest development. The framework of self-determination theory was used to conduct a field experiment involving 114 students in vocational education. These students followed a practical business course which required they work in small learning groups. During the course, students were asked to complete the Quality of Working in Groups Instrument, an online measure of how strong autonomy, competence, social relatedness, and task interest are fulfilled. SEM showed that students' psychological needs were jointly and uniquely related to task interest over time. The significance of this on-line test for the assessment of interest within project-based education is discussed.     

Precueing imminent conflict does not override sequence-dependent interference adaptation

Interference effects are largely reduced after cognitive conflicts in previous trials. This sequence-dependent interference adaptation is often seen as a consequence of strategic executive control. We sought to investigate whether sequential modulations are comparable with cue-induced strategic adjustments in spatial interference tasks. If so, reliable cues indicating the next compatibility condition should override effects caused by prior events. To this end, cues were introduced in a spatial stimulus-response compatibility task and a Simon task that either indicated the upcoming trial compatibility (rule cues) or the target position, which was not related to the S-R rule (position cues). The proportion of valid cues was either completely or predominantly valid. In both tasks cueing benefits for absolutely reliable rule cues were clearly present. Remarkably, sequential modulations were not influenced by effective rule cueing and vice versa. Even absolutely reliable information about prospective control demands did not cancel out sequence-dependent interference adaptation. In addition, the contingent negative variation—an event-related brain potential in the cue-target interval that is related to response preparation and readiness—showed additive effects of preceding compatibility and cue reliability. The present results indicate that processes underlying sequence-dependent interference adaptation differ from cue-induced strategic processes of cognitive control.     

French native speakers in the making: From language-general to language-specific voicing boundaries

By examining voice onset time (VOT) discrimination in 4- and 8-month-olds raised in a French-speaking environment, the current study addresses the question of the role played by linguistic experience in the reshaping of the initial perceptual abilities. Results showed that the language-general −30- and +30-ms VOT boundaries are better discriminated than the 0-ms boundary in 4-month-olds, whereas 8-month-olds better discriminate the 0-ms boundary. These data support explanations of speech development stressing the effects of both language-general boundaries and linguistic environment (attunement theory and coupling theory). Results also suggest that the acquisition of the adult voicing boundary (at 0 ms VOT in French vs. +30 ms VOT in English) is faster and more linear in French than in English. This latter aspect of the results might be related to differences in the consistency of VOT distributions of voiced and voiceless stops between languages.     

The Proportion of Women Managers: Where Is the Critical Mass?1

This study examined the impact of proportions of women in management on attitudes of coworkers from two theoretical perspectives. According to Kanter (1977), women's competence, contribution to organizational culture, and status would be better appreciated as their proportion increased. According to Blalock (1967), men would react adversely. Data were collected from 453 managers in Canadian federal departments where the proportions varied from 9%, 20%, 35%, to 45%. Findings did not support either theory. Men made significantly more positive evaluations of women's participation in the organization and of their status in conditions above 20% than in the token condition. In the 45% sample, they recognized women's managerial talents significantly better. Women displayed confidence in their talents, irrespective of proportions. Results are discussed in the light of the influence of individual factors taken into account.     

Alcohol-Involved Rapes: Are They More Violent?

Alcohol's psychological, cognitive, and motor effects contribute to rape. Based on theory and past research, we hypothesized that there would be a curvilinear relationship between the quantity of alcohol consumed by perpetrators and how aggressively they behaved. Moderate levels of intoxication encourage aggressiveness; however, extreme levels severely inhibit cognitive and motor capacity. We also hypothesized that victims' alcohol consumption would have a curvilinear relationship to their resistance. These hypotheses were examined with data from 132 college women who had been the victims of attempted or completed rape. Although there was a curvilinear result for perpetrators, the slope of the curve suggested that aggressiveness was worst when no alcohol or the highest levels of alcohol were consumed. There was a negative linear relationship between victims' alcohol consumption and resistance. Difficulties associated with accurately assessing degree of intoxication from survey data are discussed and suggestions are made for improving alcohol measurement in rape research.     

‘When Difference Gets in the Way’: Young People,Whiteness and Sexualisation

Scholars of young people and sexualisation have noted an omission of studies that attend to race and whiteness. In the main, a white-Anglo middle-class child is placed at the centre of media, policy and academic debates about the effects, production and consumption of sexualised media. In light of this, it is important to ask: how can research in this area disrupt the tendency to place normative white subjects at the centre of debates, and position ‘raced others’ at the sidelines? Drawing on postcolonial and critical race and whiteness theory, this paper presents the findings from a study undertaken in South Australia with young people and young adults from a broad variety of cultural backgrounds. Through a series of focus groups designed to explore participant views of sexualised media, a powerful set of resistant narratives emerged. Firstly, participants discussed how their views on sex and sexuality are often read ‘through difference’. They revealed how ‘difference gets in the way’, frustrating conversations they want to have about sexy media, along with moments when they felt stereo-typed and type-cased. Secondly, by presenting perspectives of sexualised media on their own terms, participant narratives were not constrained or bounded by fixed cultural viewpoints. Through a series of ‘transitional moves’, participants employed notions of freedom, individual choice and rights, expressing an urgent desire to speak ‘outside of difference’.
