Discrimination and categorization of actions by pigeons

Recognizing and categorizing behavior is essential for animals (e.g., during mate selection, courtship, and avoidance of predators). In a study examining if and how animals classify different actions, a go/no-go procedure was used to train 4 pigeons to discriminate among "walking" and "running" digital animal models (each portrayed from 12 different viewpoints). Action discrimination acquired for two models significantly transferred to six novel animal models moving in novel and biomechanically characteristic ways. Randomization of frame order in the animated sequences, stimulus inversion, and static presentation all disrupted this discrimination, whereas changes in the direction and speed (both increases and decreases) of the actions did not. These results suggest that the pigeons discriminated the behaviors on the basis of generalized recognition of the models' sequence of poses across time and provide the best evidence yet that animals use action categories to identify contrasting behavioral units.     

Exploration of values: Israeli teachers’ professional ethics

The main purpose of this study was to explore Israeli teachers’ professional ethics and values using the Facet Theory (Guttman in Psychmetrika 33:469–506, 1968). Since Israel does not have a teachers’ code of ethics, such exploration can be a basis for constructing one. The study is mainly exploratory, and the main hypotheses that guided the study were based upon universal structure of values (Pakizeh et al. in J Exp Soc Psychol 43(3): 458–465, 2007 Schwartz, in Advances in experimental social psychology. Academic Press, San Diego, 1992), and were examined using a mapping sentence. The initial findings showed the data deployment on the SSA map exhibits both a radial and an angular form in a Radex configuration. Israeli teachers believe that professional ethics is based on conditioned values. The variables in the SSA map appear in a radial configuration forming three concentric circles: personal values, social values, and universal values. The components representing the code of ethics were deployed in an angular form showing three elements: professionalism, reliability and honesty, and decency.     

Cultural modulations of space–time compatibility effects

The representation of elapsing time may require spatial attention. In certain circumstances, this spatial representation develops from left to right. This is suggested by a performance advantage in responding short with the left hand and long with the right hand (spatial–temporal association between response codes [STEARC]). The present study tests whether one possible determinant of the directionality of the STEARC effect is cultural. In particular, we investigated whether reading/writing habits can affect STEARC direction by administering a visual time judgment task to Italian participants, who were exposed to a left-to-right reading/writing system, and Israeli participants, who mainly used a right-to-left system. The Italian participants showed a left-to-right STEARC effect, while this effect was not present in the Israeli group. The study demonstrates that cultural habits can influence the way in which spatial attention supports the representation of time, similar to the pattern found in other nonspatial domains such as numbers.

Optimism buffers the detrimental effect of negative self-perceptions of ageing on physical and mental health

Objectives: First, to replicate previous findings on the detrimental effect of negative self-perceptions of ageing (SPA) on physical health outcomes and to expand them to the prediction of mental health; second, to test whether an optimistic outlook to the future can buffer the effect of negative SPA on physical and mental health outcomes.

Design: Data for this study comes from the 2008 and 2011 waves of the German Ageing Survey (DEAS; n?=?6205), a population-based representative survey of adults aged 40–85?years. Mean age of the participants was 61.50 (±12.1), 49.5% were women.

Main Outcome Measures: Self-rated health, physical functioning and depressive symptoms.

Results: Multiple regression analyses indicated that negative SPA predicted deterioration in the three health outcomes over a three-year period, controlling for demographics and illnesses. The most remarkable finding is the interaction with optimism: People who were prepared for physical losses (negative SPA), and who were nevertheless optimistic, were better able to maintain better physical functioning, and lower depressive symptoms.

Conclusion: A multidimensional perspective on ageing, considering both gains and losses at the same time, seems to be best for the maintenance of good health. Individual and societal positive views of ageing should be encouraged.     

Changes over time from baseline poor self-rated health: For whom does poor self-rated health not predict mortality?

The aim of this study was to understand for whom and why poor self-rated health (SRH) is a less valid predictor of longevity or future health by examining the predictors of decline in health among people with poor baseline SRH. The sample included 409 participants in the Cross-Sectional and Longitudinal Study of the old–old (75+) in Israel, who were self-respondents and rated their health as poor at baseline and their status was known at follow-up 3.5 years later: deceased/moved to proxy interview/remained in poor SRH/or improved SRH. Baseline measures included self-reported medical status, physical, cognitive, psychological and social functioning. Findings showed that less decline in health was predicted by less difficulty in physical and cognitive functioning at baseline and by a more active physical and social life, after controlling for socio-demographics. Most of the predictors retained a unique contribution in a multivariate model, suggesting that engagement in meaningful activities serves as an indicator of better health and longer survival even within a group of old–old people in poor health. It may reflect greater social support, contribute to fitness and/or provide a sense of mastery, which could explain similar findings regarding gender and race/ethnicity groups for whom SRH is a less potent predictor of mortality.     

Rape Myths and Social Distance Toward Sex Offenders and Victims among Therapists and Students

This study was designed to investigate the relationships between gender role stereotypes, rape myths, and social distance from sex offenders and sex crime victims among students and therapists. A Rape Myth Acceptance Scale, an Attitude Variables Questionnaire, and a Social Distance Scale were administered to 125 female social science students and 51 female therapists. The findings validated our hypothesis: traditional gender role attitudes and belief in rape myths were positively related to social distance. Although therapists were willing to be in social contact with both victims and offenders to a much greater degree than were students, both groups expressed a decline in willingness to have social contact with victims and offenders, especially when the relationships were closer and more intimate. It seems that three decades after the first studies of rape myths, prejudices and stereotypes concerning rape and rape victims still exist.     

Age differences in motivational orientation toward physical activity: an application of social-cognitive theory

According to social-cognitive theory, an individual's motivation to engage in physical activity is based on three postulates: self-efficacy, outcome expectations, and self-evaluated satisfaction or dissatisfaction. The purpose of the present study was to examine age, gender, level of education, and level of activity in relation to those postulates in 2,298 Australians aged between 18 and 78. The authors conducted regression analyses for self-efficacy and for outcome expectations as dependent variables; age, gender, education level, and level of physical activity served as independent variables. Chi-square analyses assessed differences in the health incentive to exercise, the perceived level of activity, and the perceived level of fitness. Results indicated significant age differences on all variables. The older individual felt lower self-efficacy in relation to physical activity and expected fewer benefits from participating in physical activity. However, older individuals who engaged in physical activity rated themselves as more active and fit than nonexercisers of their same age and gender. Physical activity and level of education were positively correlated with self-efficacy, and men were more efficacious than women were. The implications are that interventions aimed at increasing participation in physical activity should take into consideration differences in incentives.     

The relationship of activity restriction and replacement with depressive symptoms among older adults

Activity restriction is known to mediate the disease-depression relationship. Data from 423 older Israeli adults showed that having to give up activities because of failing health was related to more depressive symptoms (DS), whereas satisfactorily replacing these activities was related to DS levels comparable to those of healthier older adults. Giving up and replacing activities mediated, in part, the effect of functional limitations on DS, after controlling for health status, demographics, and resources. Such questions about activities given up and replaced could contribute to the means of assessing the extent and impact of functional limitations on older adults.     

A normative perspective on motivation

Understanding the effects of motivation on instrumental action selection, and specifically on its two main forms, goal-directed and habitual control, is fundamental to the study of decision making. Motivational states have been shown to 'direct' goal-directed behavior rather straightforwardly towards more valuable outcomes. However, how motivational states can influence outcome-insensitive habitual behavior is more mysterious. We adopt a normative perspective, assuming that animals seek to maximize the utilities they achieve, and viewing motivation as a mapping from outcomes to utilities. We suggest that habitual action selection can direct responding properly only in motivational states which pertained during behavioral training. However, in novel states, we propose that outcome-independent, global effects of the utilities can 'energize' habitual actions.
