The Main Contributors to a Future Utopia

Which people, events, movements, institutions, and documents in the history of humankind have contributed most to the possible realization of a future utopia (i.e., a time when the Golden Rule is universally lived by)? This study consisted of two phases. The first phase involved generating nominated lists from over 100 graduate students and professionals in a variety of fields. In the second phase, the two resultant lists of 155 people and 122 events, movements, institutions, and documents were sent to a randomly-selected list of 400 tenured and tenure-track history and philosophy professors at 40 randomly-selected public Research 1 universities. These professors were asked to select who and what would be on their ‘A’ lists. The most frequently-selected people included Mohandas Gandhi, Martin Luther King, Jr., and Buddha. The most-frequently selected events, movements, institutions, and documents included: the Abolitionist movement, the American Bill of Rights, and the Abolishment of Apartheid in South Africa. The lists are presented and discussed.     

Conditioned fear is modulated by D2 receptor pathway connecting the ventral tegmental area and basolateral amygdala

Excitation of the mesocorticolimbic pathway, originating from dopaminergic neurons in the ventral tegmental area (VTA), may be important for the development of exaggerated fear responding. Among the forebrain regions innervated by this pathway, the amygdala is an essential component of the neural circuitry of conditioned fear. The functional role of the dopaminergic pathway connecting the VTA to the basolateral amygdala (BLA) in fear and anxiety has received little attention. In vivo microdialysis was performed to measure dopamine levels in the BLA of Wistar rats that received the dopamine D(2) agonist quinpirole (1 μg/0.2 μl) into the VTA and were subjected to a fear conditioning test using a light as the conditioned stimulus (CS). The effects of intra-BLA injections of the D(1) antagonist SCH 23390 (1 and 2 μg/0.2 μl) and D(2) antagonist sulpiride (1 and 2 μg/0.2 μl) on fear-potentiated startle (FPS) to a light-CS were also assessed. Locomotor performance was evaluated by use of open-field and rotarod tests. Freezing and increased dopamine levels in the BLA in response to the CS were both inhibited by intra-VTA quinpirole. Whereas intra-BLA SCH 23390 did not affect FPS, intra-BLA sulpiride (2 μg) inhibited FPS. Sulpiride's ability to decrease FPS cannot be attributed to nonspecific effects because this drug did not affect motor performance. These findings indicate that the dopamine D(2) receptor pathway connecting the ventral tegmental area and the basolateral amygdala modulates fear and anxiety and may be a novel pharmacological target for the treatment of anxiety.     

Psychological factors related to eating disordered behaviors: a study with Portuguese athletes

This study analyzes eating disordered behaviors in a sample of Portuguese athletes and explores its relationship with some psychological dimensions. Two hundred and ninety nine athletes (153 male, 51.2%) practicing collective (65.2%) or individual sports (34.8%) were included. The assessment protocol included the Eating Disorder Examination Questionnaire (EDE-Q) (Fairburn & Beglin, 1994); the Sport Condition Questionnaire (Bruin et al., 2007; Hall et al., 2007); the Sport Anxiety Scale (Smith et al., 2006); the Task and Ego Orientation in Sport Questionnaire (Duda, 1992; Duda & Whitehead, 1998); the Cognitive Evaluation of Sport-Threat Perceptions (Cruz, 1994; Lazarus, 1991); and the Self-Presentation Exercise Questionnaire (Gammage et al., 2004). Results revealed that: i) no case of clinical significance was detected in the four dimensions of the EDE-Q simultaneously; ii) females scored higher on the EDE-Q Global Score, and athletes with the better sport results scored higher on the Restraint subscale; iii) athletes with a higher desire to weigh less scored higher on the EDE-Q Global Score; iv) athletes with lower scores on EDE-Q displayed more positive results on the psychological measures; v) several psychological dimensions were identified as predictors of eating disordered behaviors. In conclusion, the prevalence of eating disordered behaviors was negligible in this study, yet the relationship of this problem with personal, sport and psychological factors was evident.     

Prevalence and associated factors with body image dissatisfaction among adults in southern Brazil: A population-based study

We investigated the prevalence of body image dissatisfaction (BID) and associated factors in Florianopolis, Brazil. BID was analyzed in a sample (N = 1720) of adults through the Figure Rating Scale. The independent variables were sociodemographic factors, health behaviors, and morbidities. A multinomial logistic regression analysis was used. More men (14.2%) than women (6.1%) presented BID by being lighter than ideal (LI). Conversely, more women (66.6%) than men (46.3%) showed BID by being heavier than ideal (HI). BID by being HI was higher among older women, those with high BMI and those with a partner. In men, lower BMI and the presence of common mental disorders were associated with BID due to being LI. Advanced ages, alcohol abuse, physical inactivity, and obesity were associated with BID due to being HI. We must consider different public health interventions for men and women to reduce BID in Brazilian adults.     

Adaptation to Spanish of the Vividness of Visual Imagery Questionnaire-Revised Version (VVIQRV)

Adaptation to Spanish of the Vividness of Visual Imagery Questionnaire-Revised Version (VVIQRV). The main goal of this paper was to adapt to Spanish language and to examine the psychometric properties of the "Vividness of Visual Imagery Questionnaire-Revised Version" (VVIQRV), an instrument that can be used to assess vividness of visual imagery. The adaptation was carried out starting from the Spanish version of VVIQ and taking into consideration improvement proposals suggested in other studies. The questionnaire was then administered to a sample of 414 Spanish university students and the psychometric characteristics were estimated on the basis of the classic theory and the Rasch rating scale model (RSM). The results were convergent with previous studies and indicated that the Spanish VVIQRV has good internal consistency and can be characterized by a single main factor structure. Also, the RSM analysis showed that the increment in the number of response categories, a proposal to improve the instrument, was not appropriate.     

Development and validation of a vocational interests questionnaire revised: the CIP 4

The "Cuestionario de Intereses Profesionales (CIP, Vocational Interests Questionnaire)" was developed by Fogliatto et al in three different versions: a paper and pencil-based one, a computer-based one, and a revised form. The instrument was originally created for the assessment of vocational interests of adolescents assisting the last years of the secondary school in Argentina. The aim of the present study was to adapt the inventory for the adolescents coursing the initial period of the secondary school. Psychometric studies analyzing the factorial structure of the instrument and internal consistence of their scales were accomplished. Additionally, evidences of criterion validity concerning to a specialized field of the secondary school and career choice intentions were analyzed. Results bring initial validity evidence of this new version of the CIP, which its main utility is career counseling applied to late-adolescence. Further studies are required in order to validate this instrument for being utilized in counseling of adolescent facing decisions related to specialty choice of the secondary school.     

One-dimensional and multi-dimensional studies of the exocentric distance estimates in frontoparallel plane, virtual space, and outdoor open field

The aim of this study is twofold: on the one hand, to determine how visual space, as assessed by exocentric distance estimates, is related to physical space. On the other hand, to determine the structure of visual space as assessed by exocentric distance estimates. Visual space was measured in three environments: (a) points located in a 2-D frontoparallel plane, covering a range of distances of 20 cm; (b) stakes placed in a 3-D virtual space (range = 330 mm); and (c) stakes in a 3-D outdoors open field (range = 45 m). Observers made matching judgments of distances between all possible pairs of stimuli, obtained from 16 stimuli (in a regular squared 4 x 4 matrix). Two parameters from Stevens' power law informed us about the distortion of visual space: its exponent and its coefficient of determination (R2). The results showed a ranking of the magnitude of the distortions found in each experimental environment, and also provided information about the efficacy of available visual cues of spatial layout. Furthermore, our data are in agreement with previous findings showing systematic perceptual errors, such as the further the stimuli, the larger the distortion of the area subtended by perceived distances between stimuli. Additionally, we measured the magnitude of distortion of visual space relative to physical space by a parameter of multidimensional scaling analyses, the RMSE. From these results, the magnitude of such distortions can be ranked, and the utility or efficacy of the available visual cues informing about the space layout can also be inferred.     

Distance perception in a natural outdoor setting: is there a developmental trend to overconstancy?

The main purpose of the present study was to investigate whether in natural environment, using very large physical distances, there is a trend to overconstancy for distance estimates during development. One hundred and twenty-nine children aged 5 to 13 years old and twenty-one adults (in a control group), participated as observers. The observer's task was to bisect egocentric distances, ranging from 1.0 to 296.0 m, presented in a large open field. The analyses focused on two parameters, constant errors and variable errors, such as measuring accuracy and precision, respectively. A third analysis focused on the developmental pattern of shifts in constancy as a function of age and range of distances. Constant error analysis showed that there are two relevant parameters for accuracy, age, and range of distances. For short distances, there are three developmental stages: 5-7 years, when children have unstable responses, 7-11, underconstancy, and 13 to adulthood, when accuracy is reached. For large distances, there is a two-stage development: 5-11 years, with severe underconstancy, and beyond this age, with mild underconstancy. Variable errors analyses indicate that precision is noted for 7 year-old children, independently of the range of distances. The constancy analyses indicated that there is a shift from constancy (or slightly overconstancy) to underconstancy as a function of physical distance for all age groups. The age difference is noted in the magnitude of underconstancy that occurs in larger distances, where adults presented lower levels of underconstancy than children. The present data were interpreted as due to a developmental change in cognitive processing rather than to changes in visual space perception.
