Concepts of present self,expected self,and ideal self in vocational preferences and expectations

This study investigated the hypotheses that similarity of ideal self and occupational stereotypes are important in determining the vocational preferences of adolescents, while similarity between expected self and occupational stereotypes is important in determining their occupational expectations. Subjects were 97 male and 88 female high school students. Findings were consistent with the view that ideal self played an important role in determining vocational preferences for males and females. However, contrary to expectations, ideal self was more strongly associated than expected self with vocational expectations for females, though not for males.     

Effect of positive,negative, and mixed occupational information on cognitive and affective complexity

A series of concentrated research studies over the past 8 years has significantly demonstrated that cognitive complexity in the vocational realm is positively related to congruence or appropriateness of vocational choice. Moreover, research has shown that introducing occupational information significantly reduces, rather than increases, cognitive complexity. The results of the study reported here relate to changes in cognitive complexity as a function of the type of occupational information introduced, namely, information with respect to the advantages of occupations; the disadvantages of occupations, or a combination of positive and negative features of occupations. Our results clearly demonstrated that while positive occupational information alone leads to greater simplicity, negative or mixed information significantly retards the trend toward greater simplicity. Results are discussed from both theoretical and practical perspectives, especially with reference to the typical occupational information provided in routine vocational counseling.     

Effects of varied response modes upon dichotic consonant-vowel identification latency

Reaction times for two right-handed subjects who received 6000 trials of dichotic stop-vowels were obtained under response conditions involving the left hand, right hand, and neck muscles. Results indicated latencies were shorter (150+ msec) when targets were presented to the right rather than the left ear. Large and stable differences in latencies remained invariant with the mode of response. Reaction times did not vary as a function of the target's place or manner of articulation. The relationship between obtained measures of latency and percentage correct ruled out speed-accuracy trade-offs as a source of the obtained differences in latencies.     

The word order problem in agrammatism : I. Comprehension

The results of a picture-pointing comprehension test show that agrammatic aphasics have difficulty understanding sentences in which the underlying semantic roles are marked by the order of noun phrases around a verbal element. Agrammatic patients performed poorly on reversible constructions involving spatial prepositions (e.g., “The square is above the circle”) and verbs (e.g., “The dancer applauds the clown”). These results have significance for the interpretation of the underlying disturbance in agrammatism—whether the deficit is syntactic or purely phonological.     

Decomposing the reaction time distribution: Pure insertion and selective influence revisited

This paper investigates the consequences of extending the assumptions of pure insertion and selective influence (popular in RT theorizing) to the level of the distribution. In the case of pure insertion and under the additional assumption that the additive random variable is exponentially distributed, a solution is obtained which not only allows estimation of the exponential-rate parameter but also provides a test of the assumptions. The result is shown to be applicable not only when processing is serial but also for certain parallel models. In addition, discrimination between self-terminating and exhaustive search strategies is provided, and in the case of either, both parameter estimation and tests of the model are possible. Extensions to nonexponential models are investigated and a general method of moments solution is outlined. In the case of selective influence a general nonparametric alternative to Sternberg's additive factor method is developed. The problem of empirical estimation and application is then considered. Simulations which place bounds on the type I and II error are reported. Finally the first theorem is provided an illustrative application with data from a memory scanning experiment. The results provide some support for the double assumption of pure insertion and that the additive random variable is distributed exponentially.     

Development of speech and language following bilateral frontal lesions

Language and speech were studied in a young child with perinatally acquired bifrontal lesions. Bilateral frontal pathology seriously interfered with the development of intelligible speech and resulted in a persistent expressive aphasia. Analysis of the neuropsychological profile indicated impairments in intelligence and language comprehension. These deficits, however, were considered secondary to the profound speech programming disorder. The findings indicate that, despite the plasticity of the immature central nervous system, bilateral frontal injury sustained at an early age precludes the development of intelligible speech. Furthermore, structurally intact cortical regions outside the territories of the speech zones fail to mediate normal speech and language development.     

Hegel and Sellars on the Unity of Things

ABSTRACT

I have claimed previously that Hegel and Sellars are both, in the end, monistic visionaries, though with radically different visions of the grand unity of things. In this paper I explain and defend that claim. Section one differentiates several kinds of monism; section two discusses Hegel’s vision of the underlying unity of thing, while section three does the same for Sellars. The compare-and-contrast assignment is brought to completion in section four.     

Bartlett revisited: Direct comparison of repeated reproduction and serial reproduction techniques

Bartlett developed the procedures of repeated reproduction (the same person repeatedly recalling information) and serial reproduction (people transmitting information from one person to another). Our experiment directly compared recall accuracy across these two techniques, which has not previously been reported, using DRM word lists. Recall of the initial study list words remained constant across repeated reproductions but declined markedly across serial reproductions. In contrast, recall of associated words that were not originally studied (i.e. critical words) was steady across both conditions. Because more of the original list words were forgotten across each link of the serial reproduction chain, the proportion of critical items recalled (relative to list words) increased significantly as the list passed between people. Using output bound scoring, serial reproduction resulted in lower accuracy than repeated reproduction by the final recall trial. Our results are broadly consistent with Bartlett's (1932) informal observations: Serial reproduction produces greater forgetting of the original material than does repeated reproduction and also leads to greater distortion relative to the proportion of correct material recalled.     

Signo y representación en las teorías semióticas

Resumen

Abordar de forma adecuada el problema de la representación en las teorías semióticas es una tarea difícil por dos razones fundamentales. La primera de ella es la inexistencia de una historia detallada de la semiótica; la segunda reside en la diversidad de sentidos que se han atribuido a los términos “signo” y “representación”. Para resolver ambos problemas hemos decidido realizar un examen retrospectivo de las diversas tradiciones con las que se vinculan las teorías de los dos autores a los que hay que considerar fundadores de la semiótica actual: C. S. Peirce y F. de Saussure. Trataremos de demostrar que aunque la terminología parezca coincidente, la primera está más cercana a una teoría de la semiosis como representación, mientras que la segunda podría definirse mejor como asociación. No obstante, concluiremos que ninguna de las dos es suficiente para describir las diferentes formas en que puede manifestarse la acción de los signos.     

Some Thoughts Regarding the Sensitivity of t to Error in Estimated Within-Group Variance

A. J. Riopelle (2003) has eloquently demonstrated that the null hypothesis assessed by the t test involves not only mean differences but also error in the estimation of the within-group standard deviation, s. He is correct in his conclusion that the precision of the interpretation of a significant t and the null hypothesis tested is complex, particularly when sample sizes are small. In this article, the author expands on Riopelle's thoughts by comparing t with some equivalent or closely related tests that make the reliance of t on the accurate estimation of error perhaps more salient and by providing a simulation that may address more directly the magnitude of the interpretational problem.
