Naming times for the Snodgrass and Vanderwart pictures in Spanish

We present new Spanish norms for object familiarity and rated age of acquisition for 140 pictures taken from Snodgrass and Vanderwart (1980), together with data on visual complexity, image agreement, name agreement, word length (in syllables and phonemes), and five measures of word frequency. The pictures were presented to a group of 64 Spanish subjects, and oral naming latencies were recorded. In a multiple regression analysis, age of acquisition, object familiarity, name agreement, word frequency, and word length made significant independent contributions to predicting naming latency.     

Olfactory blocking and odorant similarity in the honeybee

Blocking occurs when previous training with a stimulus A reduces (blocks) subsequent learning about a stimulus B, when A and B are trained in compound. The question of whether blocking exists in olfactory conditioning of proboscis extension reflex (PER) in honeybees is under debate. The last published accounts on blocking in honeybees state that blocking occurs when odors A and B are similar (the "similarity hypothesis"). We have tested this hypothesis using four odors (1-octanol, 1-nonanol, eugenol, and limonene) chosen on the basis of their chemical and physiological similarity (experiment 1). We established a generalization matrix that measured perceptual similarity. Bees in the "block group" were first trained with an odor A and, in the second phase, with the mixture AB. Bees in the "novel group" (control group) were first trained with an odor N and, in the second phase, with the mixture AB. After conditioning, bees in both groups were tested for their response to B. We assayed all 24 possible combinations for the four odors standing for A, B, and N. We found blocking in four cases, augmentation in two cases, and no difference in 18 cases; odor similarity could not account for these results. We also repeated the experiments with those six odor combinations that gave rise to the similarity hypothesis (experiment 2: 1-hexanol, 1-octanol, geraniol) and found augmentation in one and no effect in five cases. Thus, blocking is not a consistent phenomenon, nor does it depend on odor similarity.     

Positive emotions in volunteerism

Volunteerism is a well consolidated social phenomenon in our society. However, its rapid growth in the last few years has complicated the integration of theoretical knowledge and its application in organizational settings. Taking into account that nowadays, one of the chief problems of volunteer organizations is sustained volunteer service, the object of this work is to verify, within the context of the psychosocial model of sustained volunteerism (Vecina, 2001), the type of relation between the experience of positive emotions in volunteers and their intention of remaining in the organization. This work was carried out on a sample of volunteers who had been in service for less than one year prior to this study.     

Lexical processing of ambiguous words: dominance or associative strength?

Four experiments examined the role of meaning frequency (dominance) and associative strength (measured by associative norms) in the processing of ambiguous words in isolation. Participants made lexical decisions to targets words that were associates of the more frequent (dominant) or less frequent (subordinate) meaning of a homograph prime. The first two experiments investigated the role of associative strength at long SOAs (Stimulus Onset Asynchrony) (750 ms.), showing that meaning is facilitated by the targets' associative strength and not by their dominance. The last two experiments traced the role associative strength at short SOAs (250 ms), showing that the manipulation of the associative strength has no effect in the semantic priming. The conclusions are: on the one hand, semantic priming for homographs is due to associative strength manipulations at long SOAs. On the other hand, the manipulation of the associative strength has no effect when automatic processes (short SOAs) are engaged for homographs.     

Innovation across cultures: Connecting leadership,identification, and creative behavior in organizations

Innovation is considered essential for today's organizations to survive and thrive. Researchers have also stressed the importance of leadership as a driver of followers' innovative work behavior (FIB). Yet, despite a large amount of research, three areas remain understudied: (a) The relative importance of different forms of leadership for FIB; (b) the mechanisms through which leadership impacts FIB; and (c) the degree to which relationships between leadership and FIB are generalizable across cultures. To address these lacunae, we propose an integrated model connecting four types of positive leadership behaviors, two types of identification (as mediating variables), and FIB. We tested our model in a global data set comprising responses of N = 7,225 participants from 23 countries, grouped into nine cultural clusters. Our results indicate that perceived LMX quality was the strongest relative predictor of FIB. Furthermore, the relationships between both perceived LMX quality and identity leadership with FIB were mediated by social identification. The indirect effect of LMX on FIB via social identification was stable across clusters, whereas the indirect effects of the other forms of leadership on FIB via social identification were stronger in countries high versus low on collectivism. Power distance did not influence the relations.     

Understanding Disorders in Agrammatic Patients: Capacity or Structural Deficits?

Several hypotheses have been advanced in recent years to understand difficulties in agrammatic patients. Some of them are of a structural kind, as the deficiency is said to lie in some of the linguistic system components. Others are of a functional type, as it is stated that the problem of these patients lies in the loss of processing capacity.Using the existence of a syntactic type of structure in Spanish, that active sentences do not follow the canonical S-V-O order, we will try to prove in this article whether agrammatic patients' problems are due to memory span loss or to one of the syntactic process mechanisms. To this end, the performances of three groups of patients are contrasted. Agrammatic, anomic, and normal Spanish speakers are given several tasks of sentence–picture matching and tests of memory span.Results show that agrammatic patients have specific difficulties processing certain syntactical structures; however, their memory deficiencies are not more pronounced than in other patients. It can be concluded, therefore, that the deficiencies of agrammatic patients are of a structural character rather than due to memory span loss.     

Attitudes Toward Affirmative Action in the United States and Canada

Attitudes toward affirmative action programs were investigated using a U.S. sample, an English speaking Canadian sample, and a French speaking Canadian sample. Results indicate that cultural influences in the form of individualism-collectivism were small but that ethnic and linguistic memberships were major influences on attitudes toward those programs.     

The nature of cross-modal color-word interference effects

Cowan and Barron (1987) and Cowan (1989b) reported that color-naming performance was slowed by spoken color names drawn from the same set but presented in an order unrelated to the printed colors. Although Miles, Madden, and Jones (1989) and Miles and Jones (1989) were unable to replicate this cross-modal effect, it is replicated here in two experiments with much better experimental control than before. However, the effect is shown to depend upon the relative timing of the color and word in a way that conflicts with the theoretical account that Cowan and Barron offered. While Cowan and Barron suggested that an irrelevant color word would contaminate the response set if this word occupied short-term memory when the color was about to be named, it appears that interference actually occurs only if the memory representation was formed very recently and had not been inhibited. Further implications for processing are discussed.     

LEX I and II: Two databases of surface word forms for psycholinguistic research in Spanish

Two databases of Spanish surface word forms are presented. Surface word forms are words considered as orthographically or phonologically specified without reference to their meaning or syntactic category. The databases are based on the productive written vocabulary of children between the ages of 6 and 10 years. Statistical and structural information is presented concerning surface word-form frequency, consonant-vowel (CV) structure, number of syllables, syllables, syllable CV structure, and subsyllabic units. LEX I was intended to aid in the study of reading processes. Entries were orthographic surface word forms; words were divided in their components following orthographic criteria. LEX II was designed for spoken language research. Accordingly, words were transcribed phonologically and phonological criteria were applied in extracting the internal units. Information about stress location was also provided. Together, LEX I and LEX II represent a useful tool for psycholinguists interested in the study of people acquiring Spanish as a first or foreign language and of Spanish-speaking populations in general.     

Laudato Si’: Care for Creation at the Center of a New Social Issue

This essay reviews the documents of the pontifical magisterium of the Church from the encyclical Mater et magistra ( 1961 ) to the exhortation Evangelii gaudium (2013), in order to show the Church’s historical commitment to the defense of the environment. It then argues that Laudato si’ elevates the theological status of the environmental crisis to that of a new social issue, much as Leo XIII did for the industrial crisis with his encyclical letter Rerum novarum ( 1891 ).
