Orientation: Employees’ perceptions of their leaders’ behaviour play a role in creating empowering environments where employees are willing to do more than what is expected, with retention of employees as a result. Research purpose: The aim of this study was to theoretically conceptualise and empirically determine the relationships between employees’ perception of their leaders’ empowering behaviour, psychological empowerment, organisational citizenship behaviours and intention to leave within a manufacturing division of an organisation. Motivation for the study: In the ever-changing work environment, organisations must capitalise on their human capital in order to maintain competitiveness. It is therefore important to identify the role of employees’ perception of leadership in contributing to the establishment of an environment where employees feel empowered, are willing to do more than what is expected and want to stay in the organisation. Research design, approach and method: A non-experimental, cross-sectional survey design was used. The total population (N = 300) employed at the manufacturing division was targeted. Two hundred completed questionnaires were obtained. The Leader Empowering Behaviour Questionnaire, Measuring Empowerment Questionnaire, Organisational Citizenship Behaviour Questionnaire and Intention to Leave Scale were administered. Main findings: Employees’ perception of their leaders’ empowering behaviour (keeping employees accountable, self-directed decision-making and people development), psychological empowerment (attitude and influence) and organisational citizenship behaviours (loyalty, deviant behaviour and participation) predict intention to leave the organisation. Practical/managerial implications: Organisations should foster the elements of a positive organisation, in this case leader empowering behaviours, if they want to retain their employees. Contribution/value-add: The results of this research contribute to scientific knowledge about the positive effects of employees experiencing their leaders as empowering.
Self-narratives of patients have received increasing interest in schizophrenia since they offer unique material to study patients’ subjective experience related to their illness, in particular the alteration of self that accompanies schizophrenia. In this study, we investigated the life narratives and the ability to integrate and bind memories of personal events into a coherent narrative in 27 patients with schizophrenia and 26 controls. Four aspects of life narratives were analyzed: coherence with cultural concept of biography, temporal coherence, causal-motivational coherence and thematic coherence. Results showed that in patients cultural biographical knowledge is preserved, whereas temporal coherence is partially impaired. Furthermore, causal-motivational and thematic coherence are significantly impaired: patients have difficulties explaining how events have modeled their identity, and integrating different events along thematic lines. Impairment of global causal-motivational and thematic coherence was significantly correlated with patients’ executive dysfunction, suggesting that cognitive impairment observed in patients could affect their ability to construct a coherent narrative of their life by binding important events to their self. This study provides new understanding of the cognitive deficits underlying self-disorders in patients with schizophrenia. Our findings suggest the potential usefulness of developing new therapeutic interventions to improve autobiographical reasoning skills.
In the present work, mismatch negativity (MMN) was used to examine the contribution of spectral vs. temporal perceptual features to vowel length discrimination in children and adults. Three age groups (adults vs. 9-10 years vs. 10-11 years olds) have been taken to examine developmental effects on vowel length perception. Natural (i.e., spectrotemporal) vowel length differences were compared with (artificially modified) stimulus pairs varying only in temporal or spectral characteristics to contrast spectral, temporal and spectrotemporal processing.
The result indicates that, while adults integrate spectral and temporal aspects of the speech signal in an additive way, children of 9-10 years of age sequentially process both features. However, vowel length processing is found to become adultlike at the age of 10-11 years.

Psychological ownership is a cognitive–affective construct based on individuals’ feelings of possessiveness towards and of being psychologically tied/attached to objects that are material (e.g. tools or work) and immaterial (e.g. ideas or workspace) in nature. Research suggests that psychological ownership could be influenced by various individual, organisational and contextual factors. The South African Employment Equity Act, which was implemented to grant equitable opportunities to previously disadvantaged employees, could be a significant contextual factor affecting psychological ownership, due to perceptions associated with inequality. Ethnicity may also act as a moderator for the relationship between perceptions of employment equity and psychological ownership. The objective of this study was to investigate the relationship between employment equity perceptions and psychological ownership and to explore whether ethnicity plays a moderating role in the relationship. A cross-sectional survey design was employed with a purposeful sample of 202 respondents employed in a large South African mining house. Pearson product–moment correlations and structural equation modelling confirmed that employment equity perceptions could predict the five components of psychological ownership. However, the results revealed that ethnicity has no moderating effect on the relationship between perceptions of employment equity and the emergence of psychological ownership. By implication, organisations that seek to retain employees targeted through equity initiatives need to find ways to enhance and develop the psychological ownership of these employees. The research contributes new insights into and knowledge of how contextual factors could influence employees’ psychological ownership.
Recent research has revealed that learning behavior is associated with academic achievement at the college level, but the impact of specific learning strategies on academic success as well as gender differences therein are still not clear. Therefore, the aim of this study was to investigate gender differences in the incremental contribution of learning strategies over general cognitive ability in the prediction of academic achievement. The relationship between these variables was examined by correlation analyses. A set of t-tests was used to test for gender differences in learning strategies, whereas structural equation modeling as well as multi-group analyses were applied to investigate the incremental contribution of learning strategies for male and female students’ academic performance. The sample consisted of 461 students (mean age = 21.2 years, SD = 3.2). Correlation analyses revealed that general cognitive ability as well as the learning strategies effort, attention, and learning environment were positively correlated with academic achievement. Gender differences were found in the reported application of many learning strategies. Importantly, the prediction of achievement in structural equation modeling revealed that only effort explained incremental variance (10%) over general cognitive ability. Results of multi-group analyses showed no gender differences in this prediction model. This finding provides further knowledge regarding gender differences in learning research and the specific role of learning strategies for academic achievement. The incremental assessment of learning strategy use as well as gender-differences in their predictive value contributes to the understanding and improvement of successful academic development.
Over the last decade, the prospect of improving or maintaining cognitive functioning has provoked a steadily increasing number of cognitive training studies. Central target populations are individuals at risk for a disadvantageous development, such as older adults exhibiting cognitive decline or children with learning impairments. They rely on cognitive resources to meet the challenges of an independent life in old age or requirements at school.
To support daily cognitive functioning, training outcomes need to generalize to other cognitive abilities. Such transfer effects are, however, highly discussed. For example, recent meta-analyses on working memory training differed in the conclusion on the presence (Au et al., 2015; Karbach and Verhaeghen, 2014) or absence of transfer effects (Melby-Lervåg and Hulme, 2013). Usually training-specific design factors such as type, intensity, duration, and feedback routines are discussed as reasons for such inconsistent findings. However, even individuals participating in exactly the same training regime highly differ in their training outcomes. We argue that it is time to study the individual development during trainings to understand these differential outcomes. It is time to have a closer look at the intraindividual training data.
