Object constancy, the ability to recognize objects despite changes in orientation, has not been well studied in the auditory modality. Dolphins use echolocation for object recognition, and objects ensonified by dolphins produce echoes that can vary significantly as a function of orientation. In this experiment, human listeners had to classify echoes from objects varying in material, shape, and size that were ensonified with dolphin signals. Participants were trained to discriminate among the objects using an 18-echo stimulus from a 10° range of aspect angles, then tested with novel aspect angles across a 60° range. Participants were typically successful recognizing the objects at all angles (M = 78 %). Artificial neural networks were trained and tested with the same stimuli with the purpose of identifying acoustic cues that enable object recognition. A multilayer perceptron performed similarly to the humans and revealed that recognition was enabled by both the amplitude and frequency of echoes, as well as the temporal dynamics of these features over the course of echo trains. These results provide insight into representational processes underlying echoic recognition in dolphins and suggest that object constancy perceived through the auditory modality is likely to parallel what has been found in the visual domain in studies with both humans and animals. 相似文献

RESUMENCrespo comienza manifestando que su propósito es sondear, aunque sea de forma elemental, la posibilidad y potencial productividad de una consideración de la racionalidad como elemento explicativo dentro de una teoría social de las actitudes. El autor explica que un concepto no exclusivamente utilitario o instrumental de la racionalidad puede ser de utilidad para comprender ciertos desarrollos de la dinámica actitudinal, en concreto, aquellos en que es posible pensar que cambiamos de actitud porque somos argumentalmente convencidos. Crespo resalta la posibilidad de considerar las actitudes, entendidas como procesos de significación evaluativa o toma de postura respecto a otros significativos, como procesos sociales susceptibles de enjuiciamiento y eventualmente necesitados de legitimación o justificación. El autor finaliza su trabajo repasando extensamente algunas características del concepto de actitud en relación con su carácter evaluativo y su vinculación a la acción. Los comentarios de Amalio Blanco, Charles Antaki y Ma Dolores Avia valorando esta exposición siguen a la misma, al igual que la respuesta de Crespo a estos autores. 相似文献

As we work through our theories, we rejoice in discovering the logic of concepts and their articulation in clinical experience. Such joy hides other movements, in which the only stakes are demands for love, sexual curiosity and the satisfaction of hate, transferred from infancy to others worlds, idealised or despised. When we participate in our psychoanalytical institutions, we feel pride or even vanity to be participating in the great historical movement of psychoanalysis. This conceals the working of transference in our institutional life; transference which is crudely sexual at its origins, and implies maternal, paternal or fraternal objects. This is its constraining power. We should be fully aware of this, as Strachey or Balint have already shown, in order to attenuate the violence of transference and stimulate our creativity. Anna Freud and Melanie Klein's controversies had a reality of their own. This reality was quickly forgotten and trapped in various conflicts, as those existing between Jones and Freud or between Glover and the rest of the British Psychoanalytical Society of his times. These re-elaborations gave rise to ideological elements, which have ever since pervaded the history of psychoanalytical theory, influencing psychoanalytical methods and clinics. It is important for us today to elucidate these ideologies in order to improve our achievements. 相似文献

Over the past two decades, considerable progress has been achieved in an effort to better identify and understand the various types of organizational commitment, the foci toward which such committed bonds are directed, and the myriad outcomes associated with these bonds. This research adds to and extends such work within a military context. Specifically, we explore relations among various forms (e.g., affective, normative, and continuance) of both team- and military-focused commitment and several supervisory-rated performance criteria. Across the different criteria, team-focused commitment tended to be a stronger predictor of performance than military-oriented commitment did. However, military-oriented commitment was inversely related to supervisory ratings of soldiers' negative behaviors. We discuss the psychological mechanisms that likely drive these findings, the implications of this work, and several potentially fruitful next steps within this research domain. 相似文献

Individuals generalize differently depending on the extent of their past experiences and what they learn from them. For instance,
the peak of generalization can shift from a familiar stimulus to novel ones when the familiar stimulus has been repeatedly
discriminated from another, similar stimulus. We examined how the amount of experience students had in discriminating complex
sounds impacted their later generalization. As training increased, participants improved at distinguishing sounds, but their
tendency to respond to certain novel sounds increased. With additional training, however, this shift dissipated. The results
suggest that shifts in generalization may correspond to transitional states of perceptual learning and that learning-related
changes in perceptual sensitivities involve more than just incremental increases in feature selectivity. 相似文献

Indicators of academic achievement for bilingual students can be inaccurate due to linguistic heterogeneity. For indigenous populations, language shift (the gradual replacement of one language by another) is a factor that can increase this heterogeneity and poses an additional challenge for valid testing. We investigated whether and how indigenous populations can be validly included in a large-scale assessment program. We gave Mexican preschool Mayan students aged 5 to 6 years the same set of mathematics items in three versions: (1) original in Spanish, (2) Mayan translation, and (3) content equivalent, developed from scratch in Mayan. Also, we collected information on the students’ and the teachers’ use of Spanish and Mayan, and on the communities’ support of the two languages. Students performed poorly on the three versions. Generalizability theory-based analyses revealed considerable performance inconsistency across items and language versions and low generalizability and dependability coefficients. This performance instability appears to stem from a dwindling support of the Mayan language in Mayan schools and communities. Fair, valid assessment of indigenous populations in either their languages or their countries’ dominant languages appears to be difficult to accomplish with current testing models and policies. 相似文献

We report two experiments that explored the linguistic locus of age-of-acquisition effects in picture naming by using a delayed naming task that involved only a low proportion of trials (25 %) while, for the large majority of the trials (75 %), participants performed another task—that is, the prevalent task. The prevalent tasks were semantic categorization in Experiment 1a and grammatical-gender decision in Experiments 1b and 2. In Experiment 1a, in which participants were biased to retrieve semantic information in order to perform the semantic categorization task, delayed naming times were affected by age of acquisition, reflecting a postsemantic locus of the effect. In Experiments 1b and 2, in which participants were biased to retrieve lexical information in order to perform the grammatical gender decision task, there was also an age-of-acquisition effect. These results suggest that part of the age-of-acquisition effect in picture naming occurs at the level at which the phonological properties of words are retrieved. 相似文献
