Phonological mediation in visual masked priming: evidence from phonotactic repair

In a series of 4 experiments, the authors show that phonological repair mechanisms, known to operate in the auditory modality, are directly translated in the visual modality. This holds with the provision that printed stimuli are presented for a very brief duration and that the effect of phonological repair is tested after a delay of some 100 ms has elapsed after that presentation. The case of phonological repair chosen to exemplify the parallelism between print and speech is the prosthesis of /e/ in utterances beginning with /s/ followed by a consonant in Spanish. Native speakers of Spanish hear a prothetic /e/ in auditorily presented pseudowords such as special (/speojal/, derived from "especial") as well as stuto (/stuto/, derived from "astuto"). It is shown here that they also hear that same vowel /e/ when presented with the printed pseudowords "special" and "stuto." This finding of a phonological repair effect in print has implications for the issue of phonological activation from print, as well as for the prelexical locus and mandatory nature of phonological repair mechanisms in general.

On the role of regular phonological variation in lexical access: evidence from voice assimilation in French

The present study investigated whether lexical access is affected by a regular phonological variation in connected speech: voice assimilation in French. Two associative priming experiments were conducted to determine whether strongly assimilated, potentially ambiguous word forms activate the conceptual representation of the underlying word. Would the ambiguous word form [sud] (either assimilated soute 'hold' or soude 'soda') facilitate "bagage" 'luggage', which is semantically related to soute but not to soude? In Experiment 1, words in either canonical or strongly assimilated form were presented as primes. Both forms primed their related target to the same extent. Potential lexical ambiguity did not modulate priming effects. In Experiment 2, the primes such as assimilated soute pronounced [sud] used in Experiment 1 were replaced with primes such as soude canonically pronounced [sud]. No semantic priming effect was obtained with these primes. Therefore, the effect observed for assimilated forms in Experiment 1 cannot be due to overall phonological proximity between canonical and assimilated forms. We propose that listeners must recover the intended words behind the assimilated forms through the exploitation of the remaining traces of the underlying form, however subtle these traces may be.     

Links between sex-related expectations about alcohol, heavy episodic drinking and sexual risk among young men in a shantytown in Lima, Peru

CONTEXT: Alcohol use is frequently identified as a contributor to risky sexual behaviors; however, research results are mixed. Given the conflicting evidence, researchers have focused on other factors, such as expectations about alcohol's effects that might help explain the relationship of alcohol use and risky sexual behaviors. METHODS: Cross-sectional data from 312 sexually experienced males aged 18-30 in a shantytown in Lima, Peru, were used in logistic regression models to identify associations of heavy episodic drinking and sex-related expectations about alcohol with sexual risk behaviors. RESULTS: Heavy episodic drinking was associated with having had two or more sexual partners and having had sex with a casual partner in the past year (odds ratios, 2.8 and 2.5, respectively). After controlling for alcohol consumption, sex-related expectations about alcohol were associated with these high-risk sexual behaviors, as well as with not using a condom at last sex (1.2) and not using a condom at last sex with a casual partner (1.3). CONCLUSION: Beliefs about the effect of alcohol on sexual performance could help explain links between alcohol consumption and risky sexual behavior not completely accounted for by the pharmacological effects of alcohol.     

Discriminant validity of the ZKPQ in a sample meeting BPD diagnosis vs. normal-range controls

Widiger and Simonsen (2005) state that given the limitations of the categorical model of Personality Disorders classification proposals are to be expected for dimensional classifications. The purpose of this paper is to test the alternative five factorial model (AFFM) of personality in a sample with PDs. Subjects were administered the ZKPQ to test the discriminant capacity of the AFFM in classifying subjects diagnosed with BPD (n = 74) vs normal-range controls (n = 148) paired by age and sex, and identifying sensitive and/or specific dimensions that can be of help in diagnosing BPD. The results showed that high scores on N-Anx and Imp-SS, and low scores on Act are prognostic factors for being diagnosed with BPD. Likewise, this model correctly classified 88% of subjects with a kappa index of 0.73. The AFFM of personality appears to have a substantial power for predicting SCID-II interview-based BPD diagnosis.     

Sexual differences in memory in shiny cowbirds

Avian brood parasites depend on other species, the hosts, to raise their offspring. During the breeding season, parasitic cowbirds (Molothrus sp.) search for potential host nests to which they return for laying a few days after first locating them. Parasitic cowbirds have a larger hippocampus/telencephalon volume than non-parasitic species; this volume is larger in the sex involved in nest searching (females) and it is also larger in the breeding than in the non-breeding season. In nature, female shiny cowbirds Molothrus bonariensis search for nests without the male’s assistance. Here we test whether, in association with these neuroanatomical and behavioural differences, shiny cowbirds display sexual differences in a memory task in the laboratory. We used a task consisting of finding food whose location was indicated either by the appearance or the location of a covering disk. Females learnt to retrieve food faster than males when food was associated with appearance cues, but we found no sexual differences when food was associated with a specific location. Our results are consistent with the view that parasitism and its neuroanatomical correlates affect performance in memory tasks, but the effects we found were not in the expected direction, emphasising that the nature of avian hippocampal function and its sexual differences are not yet understood.

Task- and location-switching effects on visual attention

In two experiments, we examined the effects of task and location switching on the accuracy of reporting target characters in an attentional blink (AB) paradigm. Single-character streams were presented at a rate of 100 msec per character in Experiment 1, and successive pairs of characters on either side of fixation were presented in Experiment 2. On each trial, two targets appeared that were either white letters or black digits embedded in a stream of black letter distractors, and they were separated by between zero and five items in the stream (lags 1-6). Experiment 1 showed that report of the first target was least accurate if it immediately preceded the second target and if the two targets were either both letters or both digits (task repetition cost). Report of the second target was least accurate if one or two distractors intervened between the two targets (the U-shaped AB lag effect) and if one target was a letter and the other a digit (task switch cost). Experiment 2 added location uncertainty as a factor and showed similar effects as Experiment 1, with one exception. Lag 1 sparing (the preserved accuracy in reporting the second of two targets if the second immediately follows the first) was completely eliminated when the task required attention switching across locations. Two-way additive effects were found between task switching and location switching in the AB paradigm. These results suggests separate loci for their attentional effects. It is likely that the AB deficit is due mainly to central memory limitations, whereas location-switching costs occur at early visual levels. Task-switching costs occur at an intermediate visual level, since the present task switch involved encoding differences without changes in stimulus-response mapping rules (i.e., the task was character identification for both letters and digits).

RESUMEN

El presente artículo es una recopilación de las aportaciones relevantes provenientes de la psicología al II Congreso de Teoría y Metodología de las Ciencias. Este análisis no pretende a través de unos apuntes, dar una imagen con un mínimo de coherencia epistemológica de la menos parte de la gran cantidad de problemas y matices que el “apartado psicológico” del Congreso puso en la palestra. Se ha escogido para ello un camino que implica las propias posiciones epistemológicas del autor de este trabajo. y que ponen en juego reflexiones oportunas sobre las relaciones de la Psicología y la Filosofía, sacando a la luz la posibilidad de un entendimiento fructífero.     

Nuevas perspectivas en el desarrollo de la tipificación sexual y de género

RESUMEN

El autor, tras constatar la necesidad de perspectivas propiamente evolutivas que conserven las aportaciones de la psicología diferencial, repasa estos enfoques evolutivos clásicos del desarrollo psicosexual destacando la teoría cognitiva propuesta por Kohlberg (1966). Seguidamente analiza tanto los intentos posteriores de perfeccionar estos enfoques desde el punto de vista psicoanalítico, conductista y cognitivo como la aparición de nuevas perspectivas desde comienzos de los setenta: los enfoques de la “trascendencia de los roles sexuales” y los del procesamiento de la información, ofreciendo las características fundamentales que los diferencian de los clásicos. El autor se pregunta si no sería conveniente una nueva elaboración teórica que tuviera en cuenta las directrices, preocupaciones y necesidades comunes de todos ellos considerando que, para ello, se necesita clarificar previamente la taxonomización terminológica, la contextualización de los distintos contenidos y la extensión a lo largo del ciclo vital. Tras desarrollar estas tres bases de fundamentación, finaliza esbozando un nuevo modelo evolutivo de tipificación sexual y de género en torno al cual ordenar y reinterpretar los hallazgos de las investigaciones sobre el tema.
