Optimism and pessimism dimensions in the Life Orientation Test-Revised: Method and meaning

The Life Orientation Test and its revision include items tapping both the belief that good things will happen (optimism) and the belief that bad things will not happen (low pessimism). The present investigation addressed the relationship of optimism and pessimism from psychometric and substantive perspectives. Two variations of the LOT-R, one with standard items and one with extreme adverbs (e.g., “always”) removed, were administered to undergraduate (n = 971) and web-based samples (n = 2806). Although there was psychometric support for a bidimensional structure in both versions, only the revised version showed substantive differences in the correlations of optimism versus pessimism with personality criteria. The generic recommendation is to use the original, unidimensional scale.     

Measuring Care and Justice Moral Orientation: Italian Adaptation and Revision of the MMO-2 Scale

This study presents the Italian adaptation of the Measure of Moral Orientation, second revision (MMO-2). Based on Carol Gilligan’s theory of the Ethics of Care, the MMO-2 was designed to measure two complementary moral stances, namely, Care and Justice. For this study, questionnaire responses from 683 university students were assessed against an Italian-adapted MMO-2 scale. Data were analyzed through exploratory structural equation modeling first as separate scenarios and then as a single model. The final model comprises 4 intercorrelated pairs of latent variables and shows highly satisfactory goodness of fit indices with moderate construct validity and reliability. Strengths, limitations, and directions for the future developments of the MMO-2 are discussed.     

Influence of strain rate on the orientation dependence of microstructure in nickel single crystals

The deformation microstructures of nickel single crystals (99.945 wt.%) during dynamic plastic deformation and quasi-static compression to a true strain of 0.20 were comparatively investigated. The deformation microstructures are orientation dependent, forming cell structure, slip plane aligned or not slip plane aligned extended boundaries. It is found that the orientation spread decreases, remains unchanged and becomes enhanced when loading along 〈0?0?1〉, 〈0?1?1〉 and 〈1?1?1〉, respectively, as strain rate increases.     

The nature of learned categorical perception effects: a psychophysical approach

Categorical perception is often cited as a striking example of cognitive influences on perception. However, some evidence suggests the term is a misnomer, with effects based on cognitive not perceptual processing. Here, using a psychophysical approach, we provide evidence consistent with a learned categorical perception effect that is dependent on analysis within the visual processing stream. An improvement in participants' discrimination between grating patterns that they had learned to place in different categories was 'tuned' around the orientation of the patterns experienced during category learning. Thus, here, categorical perception may result from attentionally modulated perceptual learning about diagnostic category features, based upon orientation-selective stages of analysis. This argues strongly that category learning can alter our perception of the world.     

Right wing authoritarianism,social dominance orientation and the dimensions of generalized prejudice

Prior research suggests that individuals' prejudiced attitudes form a single generalized dimension predicted by Right Wing Authoritarianism (RWA) and Social Dominance Orientation (SDO). A dual process approach, however, expects different domains of generalized prejudice that relate differentially to RWA and SDO. To test this, 212 participants rated attitudes to 24 typically disliked groups. Factor analysis revealed three distinct generalized prejudice dimensions. Hierarchical Linear Modelling indicated that attitudes towards a ‘dangerous’ groups domain was significantly related only with RWA, attitudes toward a second ‘derogated’ groups domain was related only to SDO, and attitudes toward a third, ‘dissident’ groups, domain was significantly related to both, but powerfully with RWA and weakly with SDO. These findings have implications for explaining and reducing prejudice. Copyright © 2006 John Wiley & Sons, Ltd.     

Time-space learning in homing pigeons (<Emphasis Type="Italic">Columba livia</Emphasis>): orientation to an artificial light source

Time-space learning reflects an ability to represent in memory event-stimulus properties together with the place and time of the event; a capacity well developed in birds. Homing pigeons were trained in an indoor octagonal arena to locate one food goal in the morning and a different food goal in the late afternoon. The goals differed with respect to their angular/directional relationship to an artificial light source located outside the arena. Further, the angular difference in reward position approximated the displacement of the sun's azimuth that would occur during the same time period. The experimental birds quickly learned the task, demonstrating the apparent ease with which birds can adopt an artificial light source to discriminate among alternative spatial responses at different times of the day. However, a novel midday probe session following successful learning revealed that the light source was interpreted as a stable landmark and not as a surrogate sun that would support compass orientation. Probe sessions following a phase shift of the light–dark cycle revealed that the mechanism employed to make the temporal discrimination was prevailingly based on an endogenous circadian rhythm and not an interval timing mechanism.     

Investigating Australian education students’ views about spiritual well‐being,as compared with teachers in schools

Education students in Australian state and Christian universities expressed their views on ideals, lived experience, and help expected from schools in four domains of spiritual well‐being (personal, communal, environmental, and transcendental) (SWB), using the Spiritual Health and Life‐Orientation Measure (SHALOM). Students’ lived experiences greatly affected their views on help provided by schools to nurture students’ SWB. Currently, the more religious students in Christian universities reported support for their SWB from religious activities, whereas students in the state university gained support from more humanistic sources. But is this sufficient? Education students in state universities are likely to maintain the status quo regarding SWB in state schools. They report levels of help for students in line with current teachers’ views. Christian university education students have lower expectations of schools than current teachers in Christian schools. However, some positive action is being taken in Christian universities to address the spiritual formation of their students. Further opportunities are needed within teacher education and schools in Australia for staff to address this area of vital concern for their own and students’ SWB.     

Developmental changes in face recognition during childhood: Evidence from upright and inverted faces

Adults are experts at recognizing faces but there is controversy about how this ability develops with age. We assessed 6- to 12-year-olds and adults using a digitized version of the Benton Face Recognition Test, a sensitive tool for assessing face perception abilities. Children's response times for correct responses did not decrease between ages 6 and 12, for either upright or inverted faces, but were significantly longer than those of adults for both face types. Accuracy improved between ages 6 and 12, significantly more for upright than inverted faces. Inverted face recognition improved slowly until late childhood, whereas there was a large improvement in upright face recognition between ages 6 and 8, with a further enhancement after age 12. These results provide further evidence that during childhood face processing undergoes protracted development and becomes increasingly tuned to upright faces.     

Personality,epistemology and psychotherapists' choice of theoretical model: a review and analysis

This article reviews a body of research, empirical and speculative, describing variables thought to determine a psychotherapist's choice of theoretical orientation. The review finds two types of variables (1) the influences of training, colleagues, supervisors, initial clinical experience and (2) the effects of personality traits and epistemological values, beliefs and philosophy. The weight of evidence from the reviewed studies of cognitive behavioural/behavioural and psychodynamic psychotherapists, and an analysis of the data, suggests that personality and epistemic traits are significantly involved in orientation choice. This has implications for training, practitioner and client outcome satisfaction, and understanding the poor communication that exists between these two major orientations.
