The major features of comtemporary psychology in Catalonia, a principality of Spain, are described. Training, licensing, and employment are explored within the context of recent regional advancements in the discipline of psychology. These advances are viewed from an historical perspective in which recent progress in psychology in highlighted against a backdrop of political reforms emerging out of the new Spanish democratic constitution and the consignment of educational/professional development and oversight to the autonomous State Government of Catalonia.  相似文献

Animals commonly use feature and spatial strategies when remembering places of interest such as food sources or hiding places. We conducted three experiments with great apes to investigate strategy preferences and factors that may shape them. In the first experiment, we trained 17 apes to remember 12 different food locations on the floor of their sleeping room. The 12 food locations were associated with one feature cue, so that feature and spatial cues were confounded. In a single test session, we brought the cues into conflict and found that apes, irrespective of species, showed a preference for a feature strategy. In the second experiment, we used a similar procedure and trained 25 apes to remember one food location on a platform in front of them. On average, apes preferred to use a feature strategy but some individuals relied on a spatial strategy. In the final experiment, we investigated whether training might influence strategy preferences. We tested 21 apes in the platform set-up and found that apes used both, feature and spatial strategies irrespective of training. We conclude that apes can use feature and spatial strategies to remember the location of hidden food items, but that task demands (e.g. different numbers of search locations) can influence strategy preferences. We found no evidence, however, for the role of training in shaping these preferences.  相似文献

This article presents the construction, exploratory dimensionality analysis (Study 1), and validation (Study 2) of the self-report and 36-item Individuation Test for Emerging Adults (ITEA). It is the first instrument to measure different aspects of individuation (in relation to mother and father) specifically in emerging adulthood. The construct validity of the final 5-factor structure (Support Seeking, Connectedness, Intrusiveness, Self-Reliance, and Fear of Disappointing the Parent) was satisfactory. The results of multigroup analyses demonstrated that the factor structure is stable across male and female emerging adults for ITEA assessments in relation to both mother and father. The ITEA scales also show good internal consistency and concurrent validity against Emotional, Conflictual, and Functional Dependence scales of the Psychological Separation Inventory.  相似文献

The goal of this study is to explore the personality of experienced professional lifeguards in terms of Eysenck and Eysenck's PEN model of personality and Zuckerman's sensation seeking trait. A sample of 144 male professional lifeguards were contrasted with three different samples: (1) a general population sample; (2) a sample of individuals engaged in physically risky sports; and (3) a sample of prosocial physically risky professionals. It was found that lifeguards resembled most closely the prosocials followed by the sportsmen and finally the general population. The most frequent and largest differences between lifeguards and the comparison groups were found on extraversion, experience seeking, and neuroticism. The implications for lifeguard selection procedures and future research are discussed.  相似文献

Despite current interest in dog (Canis familiaris) cognition, very little is known about how dogs represent objects and how they compare with other species, such as the great apes. Therefore, we investigated how dogs and great apes (chimpanzees [Pan troglodytes], bonobos [Pan paniscus], orangutans [Pongo pygmaeus], gorillas [Gorilla gorilla]) individuate objects in a classical violation of expectation paradigm. We used a container (magic cup) with a double bottom that allowed us to change the type of food that subjects had seen being placed in the container. Using a 2 × 2 design, we varied whether subjects received a generally preferred food and whether the food was substituted (surprise trials) or not (baseline trials). Apes showed increased begging and looking behaviors and dogs showed increased smelling behavior. Both species stayed near the experimenter more frequently in the surprise trials compared with baseline trials. Both species reacted to positive (i.e., good food substituted for bad food) and negative (i.e., bad food substituted for good food) surprises. These results suggest that apes and dogs were able to individuate objects according to their properties or type in comparable ways. In addition, we looked for frustration and elation effects, but subjects' behaviors were not influenced by the food they saw and which they received in previous trials.  相似文献

The purpose of this study was to compare the gender role orientation and gender role classification of female and male athletes to those of their nonathlete counterparts. A total of 463 athletes and 378 nonathletes completed the Bem Sex Role Inventory. The findings indicated that athletes score higher on the masculinity and femininity subscales than do nonathletes. Men had higher scores on masculinity than did women, whereas women had higher scores on femininity than did men. In addition, both men and women athletes were mostly classified in the androgynous category. These findings are discussed in relation to the competitive sport environment and Turkish society.  相似文献
