Optimism and positive body image in women: The mediating role of the feared fat self

We predicted that an expectancy judgment about acquiring a feared fat self and an expectancy judgment about acquiring a hoped-for thin self would mediate dispositional optimism on positive body image. We also predicted that the mediation pathway through the feared self would be significantly stronger than that through the hoped-for self. Participants were 208 female college students who reported their age, height and weight and completed measures of dispositional optimism, the likelihood of acquiring the feared fat and hoped-for thin selves, and positive body image. Statistical analyses revealed that only the perceived likelihood of acquiring the feared fat self mediated dispositional optimism on positive body image. Implications for future research are discussed.     

Unconscious and conscious priming by forms and their parts

Using metacontrast masking techniques, in two experiments we compare unconscious and conscious response priming by targets consisting of either whole forms or else their parts. In Experiment 1 we investigate the contribution of whole forms and their figural primitives, viz., edges and corners, to the unconscious priming effect. As expected, choice RTs were fast when the invisible target and visible mask shape pairings were congruent and slower when they were incongruent. This trend, while strongest for whole-targets, also held for the target primes composed only of corners but did not hold for target primes composed only of sides. Experiment 2 showed, replicating the results of Experiment 1, that while invisible corner targets produced weaker priming effects than invisible whole targets, paradoxically visible corner target produced stronger priming effects than visible whole targets. Taken together the results of the two experiments indicate (a) that unconscious target representations and, thus, unconscious priming effects are strongest when the target is a complete rather than a partial configuration, (b) that conjunctions of line or edge orientations forming corners produce stronger unconscious target representations and priming effects than do unconscious target representations formed from nonconjoined edge or line primitives, (c) that metacontrast masking of form occurs at or beyond levels of visual processing at which feature integration of visual form primitives occurs, and (d) that, when consciously perceived, partial forms can act as stronger primes than whole forms.     

Studying radical organizational innovation through grounded theory

The main aim of this article is to study the social processes occurring during the implementation of radical organizational innovation. Our aim is to understand the nature of the development of radical innovation by identifying the social processes, that are taking place. The perspective for the analysis stems from “grounded theory” as a generative and inductive analytical strategy (Glaser & Strauss, 1967). An in-depth case study was thoroughly analysed. A total of 14 indepth interviews were conducted with key informants selected according to “theoretical sampling” criteria. The systematic use of the “constant comparative method” allowed us to differentiate grounded theories leading to a “conceptual saturation” of the categories generated from the empirical data. Results show the emergence of two basic processes, “learning” and “adaptation”, during the development of radical innovation. A “grounded” theory concerning the development of radical innovation is proposed, emphasizing the organization's selfregulating capacity for learning and adapting. Our results describe innovation as an adaptable response that causes disorder in terms of “a creative tension in the system”. Finally, the methodological implications of grounded theory are discussed with regard to the study of radical innovation. The requisites and limitations observed in using grounded theory are outlined.     

The moderator role of followers’ personality traits in the relations between leadership styles,two types of task performance and work result satisfaction

Authentic leadership is changing our understanding of what makes good leadership. However, few studies have explored how followers’ individual differences and the nature of the task they perform affect its relation to followers’ work outcomes. We examine the moderator role of two core task types (intellective vs. generative) and two personality traits (conscientiousness and emotional stability) in the relationship between two leadership feedback styles (authentic vs. transactional) and task performance or work result satisfaction in a two-wave experiment. The sample consisted of 228 participants enrolled in an organizational psychology course, 34% of whom had work experience. Our results show that over time the effect of an authentic feedback style on task performance became stronger for those participants who previously scored very low on intellective tasks or very high on generative tasks. Furthermore, a significant three-way interaction between these two traits and our leadership feedback styles indicates that the effect of authentic feedback conforms different patterns depending on the followers’ personality traits and the type of task they perform. Moreover, authentic feedback had a stronger effect on participants’ work result satisfaction. Participants with low levels of either conscientiousness or emotional stability displayed higher levels of satisfaction in the authentic feedback condition.     

Testing relations between group cohesion and satisfaction in project teams: A cross-level and cross-lagged approach

Based on a two-dimensional perspective of group cohesion, this study examines the emergence of task cohesion and interpersonal cohesion in project teams and their roles in changes in members’ individual satisfaction with the team. Specifically, we tested a direct-effect and mediation model of the cross-level relationship between team task and interpersonal cohesion and individual satisfaction with the team over time. With a sample of 74 newly created project teams, the hypotheses were tested using a two-wave panel design. Results indicate that task cohesion emerges more strongly than interpersonal cohesion during the first stages of work in project teams. Moreover, the cross-lagged relationship between team interpersonal cohesion and individual satisfaction with the team was mediated by team task cohesion.     

On patients’ unique self-knowledge

Abstract

Patients contribute to analytic endeavors through a knowledge of their own unique ways of organizing their experience, of building an intersubjective space with significant others, of the type of life that they consider worth living, and primarily of their specific passions and yearnings. The more that therapists allow the patients’ unique self-knowledge to influence their therapeutic perceptions and decisions, the further they will advance patients’ status as co-experts working together with the therapist to create and formulate new, richer knowledge. In the present article, it is suggested that one of the main reasons why patients’ self-knowledge is excluded from the therapeutic dialogue is that the persuasive power of the therapists’ rich and deep knowledge challenges the patients’ self-authority. Through an illustrative vignette, therapists are recommended to use a metacommunication intervention to restore the balance that has been undermined between the therapist’s authority and the patient’s self-authority.     

The face inhibition effect: Social contrast or motor competition?

This research examined the relative importance of encoding and retrieval contexts to the demonstration of concreteness effects in memory. Predictions from relational-distinctive and dual-code positions were evaluated. In the first two experiments, concreteness and recall task (free recall or cued recall) were manipulated following a relational semantic orienting task. The results showed an interaction between concreteness and recall type only when distinctive information could be accessed both within and between pairs. The third experiment showed that concreteness effects appeared under a relational, non-semantic orienting task. In the fourth experiment, we reexamined the magnitude of the concreteness effect following semantic versus non-semantic tasks and relational versus item-specific processing. Overall, the findings were inconsistent with both dual code theory and distinctiverelational view accounts of concreteness effects. An alternative "bidirectionality hypothesis" is suggested.     

Strength of default mode resting-state connectivity relates to white matter integrity in children

A default mode network of brain regions is known to demonstrate coordinated activity during the resting state. While the default mode network is well characterized in adults, few investigations have focused upon its development. We scanned 9-13-year-old children with diffusion tensor imaging and resting-state functional magnetic resonance imaging. We identified resting-state networks using Independent Component Analysis and tested whether the functional connectivity between the medial prefrontal cortex (mPFC) and posterior cingulate cortex (PCC) depends upon the maturation of the underlying cingulum white matter tract. To determine the generalizability of this relationship, we also tested whether functional connectivity depends on white matter maturity between bilateral lateral prefrontal cortex (lateral PFC) within the executive control network. We found a positive relationship between mPFC-PCC connectivity and fractional anisotropy of the cingulum bundle; this positive relationship was moderated by the age of the subjects such that it was stronger in older children. By contrast, no such structure-function relationship emerged between right and left lateral PFC. However, functional and structural connectivity of this tract related positively with cognitive speed, fluency, and set-switching neuropsychological measures.     

Shedding light on photosensitive behaviour in brown planaria (Dugesia Tigrina)

The planarian flatworm is one of the simplest animals to develop two eyecups that enable them to detect the presence and direction of light, which they typically avoid. In this study we assessed responses of planaria to different intensities of light. We found that they exhibited a graded, sigmoidal, photonegative response to light intensity. A two-octave increase in luminance (on the upward slope of the sigmoid) corresponded to a 9% increase in the speed planaria travelled to avoid light.
