Greens or space invaders: Prominent utopian themes and effects on social change motivation

One way in which individuals can participate in action to change the society they live in is through the pursuit of an ideal society or “utopia”; however, the content of that utopia is a likely determinant of its motivational impact. Here we examined two predominant prototypes of utopia derived from previous research and theory—the Green and Sci-Fi utopias. When participants were primed with either of these utopias, the Green utopia was perceived to entail a range of other positive characteristics (e.g., warmth, positive emotions) and—provided it was positively evaluated—tended to elicit both motivation and behaviour for social change. In contrast, the Sci-Fi utopia was associated with low motivation, even when it was positively evaluated. Furthermore, the Green utopia was shown to elicit greater perceptions of participative efficacy, which in turn predicted the increase in social change motivation.

Individual differences in echocardiography: Visual object recognition ability predicts cue utilization

Echocardiographers are highly specialised, skilled practitioners who play a critical role in medical imaging diagnostics. Yet, little is known about the cognitive and perceptual attributes of experts within this domain. This study was designed to examine the role of individual differences in expertise. Specifically, the contribution of a domain general visual expertise and pattern recognition, or cue utilization. Data were collected from 42 echocardiographers and 43 naïve participants. All of the participants competed the Novel Object Memory Test (NOMT). When compared, the echocardiographers were more accurate than the naïve participants. The echocardiographers also completed an echocardiography edition of the Expert Intensive Skills Evaluation 2.0, to establish behavioral indicators of context-related cue utilization. Those with relatively higher cue utilization performed more accurately on the NOMT, controlling for exposure. These results suggest that a general perceptual ability contributes to echocardiography potential and a sensitivity to cue-based learning may contribute to expertise.     

Variability in the semantic errors produced by brain-injured patients

One of the most common types of errors produced by aphasic patients during oral word production is semantic errors. However, although aphasia semantic errors are often treated as a single homogenous group, there are, in fact, several subtypes defined by the nature of the error-target relationship: paradigmatic, if the two words are category coordinates; syntagmatic, if they are associatively related but from different semantic categories; and superordinate, if the meaning of the error is broader than the meaning of the target. The goal of this study was to investigate whether or not these various subtypes of semantic errors have a similar processing origin. With this objective, we compared the patterns of semantic errors made by a group of Alzheimer patients in a picture-naming task with those made by a group of aphasic patients. We examined the percentages of the different error types, the degree of association between target and error, and the frequency values both of errors and targets. The results suggest that the three subtypes of semantic errors have different origins: the superordinate appear to arise at the semantic level, the syntagmatic at the lexical level, and the paradigmatic at both levels of processing.     

Learning to read in children with Williams syndrome

People with Williams syndrome are characterized by linguistic abilities that are higher than their level of intelligence. There is controversy concerning their reading level because there are few studies. The aim of this work was to test reading abilities in a group of school-age children with Williams syndrome. Their performance was contrasted with a control group of the same mental age. Three kinds of tasks were used: word and pseudoword reading, phonological awareness, and naming speed. Results show that the Williams syndrome children performed similarly to control children in reading accuracy but were slower in reading words and pseudowords. They were also slower in the naming speed tasks. These results suggest that Williams syndrome children do not have difficulties in developing grapheme-phoneme decoding but do present some difficulties in developing lexical reading.     

Structure of personality pathology in normal and clinical samples: Spanish validation of the DAPP-BQ

Given that the DSM taxonomy of personality disorders is flawed by severe classificatory problems, the development of alternative classificatory systems, such as the Dimensional Assessment of Personality Pathology-Basic Questionnaire (DAPP-BQ), has now become a priority. This study examined the internal consistency, second-order factor structure, and criterion validity of a Spanish translation of the DAPP-BQ in two samples: subjects with personality disorder (n = 155) and subjects from the general population (n = 300). Alpha coefficients ranged satisfactorily from .75 to .93. Four second-order factors of Emotional Dysregulation, Dissocial Behavior, Inhibitedness, and Compulsivity were obtained, which were replicable between samples and identical to those reported in the literature. Finally, disordered subjects scored significantly higher than normal subjects on 17 of the 18 DAPP-BQ traits. Some pending issues in the construction of an alternative taxonomy of personality disorders are discussed.     

Relations and effects of transformational leadership: a comparative analysis with traditional leadership styles

This study has two main goals: (a) to compare the relationship between transformational leadership and other important leadership styles (i.e., democratic versus autocratic or relations- and task-oriented leadership) and (b) to compare the effects of transformational leadership and the other styles on some important organizational outcomes such as employees' satisfaction and performance. For this purpose, a sample of 147 participants, working in 35 various work-teams, was used. Results show high correlations between transformational leadership, relations-oriented, democratic, and task-oriented leadership. On the other hand, according to the literature, transformational leadership, especially high levels, significantly increases the percentage of variance accounted for by other leadership styles in relevant organizational outcome variables (subordinates' performance, satisfaction and extra effort).     

Objective age of acquisition norms for a set of 328 words in Spanish

Age of acquisition is one of the most important variables in picture naming. For this reason, a large number of findings concerning age-of-acquisition data have been published in recent years in a number of different languages. In this article, objective age-of-acquisition data in Spanish for 328 pictures were collected from a pool of 760 children, half of whom were boys and the other half girls. A total of 246 pictures were selected from the Snodgrass and Vanderwart (1980) set, and 82 were new pictures. Like the results of other studies, we found that objective age of acquisition correlates less than rated age of acquisition with familiarity and frequency, which indicates that the objective measure is less contaminated by other variables than are rated estimates. A very high correlation was obtained between the norms from this study and those published in English, French, Icelandic, and Italian. These norms will be very useful to Spanish psycholinguists and clinicians. Related materials may be downloaded from the Psychonomic Society Web archive at www.psychonomic.org/archive/.     

Volunteer Engagement: Does Engagement Predict the Degree of Satisfaction among New Volunteers and the Commitment of Those who have been Active Longer?

This study examines the concept of engagement in samples of volunteers from different non‐profit organisations. Study 1 analyzes the psychometric properties of the abbreviated version of the Utrecht Work Engagement Scale (UWES) ( Schaufeli, Bakker, & Salanova, 2006a ). Two factorial structures are examined: one‐dimensional and three‐dimensional structures. Based on the Three‐Stage Model of Volunteers' Duration of Service ( Chacón, Vecina, & Dávila, 2007 ), Study 2 investigates the relationship between engagement, volunteer satisfaction, and intention to remain in a sample of new volunteers and the relationship between engagement, organisational commitment, and intention to remain in a sample of veteran volunteers. Moderated mediation analysis is provided using duration of service as a moderator in order to set a splitting point between new and veteran volunteers. The results of the confirmatory factor analysis suggest that the three‐factor model fits better to the data. Regarding the structural models, the first one shows that engagement is crucial to volunteer satisfaction during the first stage, while volunteer satisfaction is the key variable in explaining intention to continue. The second structural model shows that engagement reinforces the participant's commitment to the organisation, while organisational commitment predicts intention to continue. Both models demonstrate a notable decline when samples are changed.
