Phonological coding in reading comprehension: The importance of individual differences

Abstract

In two experiments, texts were presented word by word at a fixed pace to subjects high or low in test anxiety, under various concurrent interference conditions: no interference, articulatory suppression, finger tapping, unattended meaningful speech, reversed (meaningless) speech and nonword (meaningless) speech. High-anxiety subjects produced overt articulation more frequently than low-anxiety subjects, especially in the speech conditions. There was an interaction between anxiety and interference on comprehension performance: Conditions thought to interfere with phonological coding (i.e. articulatory suppression and nonword speech) were detrimental to comprehension for high but not for low-anxiety subjects; in contrast, there were no differences in comprehension performance as a function of anxiety under conditions causing no (proper) phonological interference (i.e. no interference, finger tapping and reversed speech). There were mixed results in the meaningful speech condition, partly attributable to its semantic interference component. These findings reveal that the use and importance of phonological coding in reading comprehension vary with differences in test anxiety-high-anxiety subjects are vulnerable to disruptive effects on phonological coding. This suggests that high-anxiety individuals are especially likely to resort to speech-based coding during reading, and that phonological coding has a compensatory role for them.     

Mood congruent Bias in Interpretation of Ambiguity Strategic Processes and Temporary Activation

Three experimentsinvestigated the tendency of high-anxiety individuals to interpretambiguous information in a threatening fashion. Priming ambiguous sentences (concerned with ego-threat, physical-threat, or non-threat events) were presented, followed by a disambiguating sentence in which a target word either confirmed or disconfirmed the consequence implied by the priming context. The sentences were presented word-by-word at a predetermined pace. Subjects read the sentences and pronounced the target word (naming task), which appeared either 500 msec or 1,250 msec after the onset of the last word (pre-target word) in the priming context. Results indicated that high-anxiety subjects named target words confirming threats faster than low-anxiety subjects, relative to non-threat words. Furthermore, this interpretative bias is: (a) strategic, rather than automatic, as it occurred with a 1,250-msec SOA, but not with a 500-msec SOA; (b) temporary, as it was found under evaluative stress conditions increasing state anxiety, butnot withnon-stress; and (c) specificto ego-threats, as it happened with ambiguous information concerning self-esteem and social evaluation, rather than with physical-threat-related information.     

Los efectos placebo en la psicología experimental y clínica

RESUMEN

Este trabajo comienza planteando que el término “placebo” se ha convertido en un cajón de sastre en el que los autores engloban diferentes, y a menudo opuestas y dispares, concepciones. Después de destacar la atención creciente a los efectos placebo en la psicología actual y la tendencia a la convergencia entre distintos enfoques en psicoterapia, la autora aborda las divergencias y dificultades para definir placebo aludiendo a concepciones de diferentes autores y centrándose en el planteamiento de Grünbaum (1985). Avia coincide con Brody (1985) en que el problema de nuestro desconocimiento sobre qué sea placebo afecta, recíprocamente, a nuestra falta de conocimiento sobre lo que debe considerarse terapia, ofreciendo algunas reflexiones en torno a posibles explicaciones de este fenómeno y destacando la débil frontera que separa éstas de las explicaciones sobre ciertas variables cognitivas. La autora concluye la presentación de este dossier afirmando que será a partir de la elaboración teórica y el trabajo de investigación como podremos profundizar en el conocimiento del fenómeno placebo.     

Memory retrieval in treating adult survivors of sexual abuse

Abstract

Therapists working with adult survivors of sexual abuse must be sensitive to the powerful ambivalence such clients have toward addressing their victimization. They fear experiencing the significant emotional turmoil which occurs in therapy and the powerful loyalty conflicts they encounter in their families-of-origin. Establishing rapport and allowing clients to set the pace for disclosing and addressing their abuse are critical components of the therapy process. The authors describe effective Ericksonian approaches for establishing these critical treatment elements. Ericksonian techniques for utilizing the client's internal resources and retrieving repressed memories are also discussed, followed by case examples illustrating specific hypnotic methods.     

Utilidad de ambientes en el estudio de mapas cognitivos

Resumen

Los objetivos de este estudio son, primero manipular varios parámetros estructurales como la «tipicidad semántica», la «densidad métrica» y el «trazado de calles». Segundo, analizar la influencia de los atributos semánticos de los edificios y el tipo de aprendizaje ambiental en la adquisición del conocimiento ambiental. Además, se utilizaron mapas urbanos ficticios para manipular los parámetros físicos de un contexto urbano. En el primer experimento, cuando se presentaban los atributos semánticos, las estimaciones de distancias eran significativamente más precisas que cuando no se ofrecían los atributos. En un segundo experimento, se pusieron a prueba las dos hipótesis de «tipicidad semántica» (Sadalla, Burroughs y Staplin, 1980) y «densidad métrica» (Hoyoak y Mah, 1982). Los resultados mostraron que las distorsiones estaban influidas principalmente por la densidad. Sin embargo, no había efecto de las otras variables físicas: tipicidad y estructura urbana. Se concluye que los mapas ficticios pueden producir un aprendizaje comparable al adquirido por experiencia directa.     

The time for doing is not the time for change: effects of general action and inaction goals on attitude retrieval and attitude change

Implicit in many informal and formal principles of psychological change is the understudied assumption that change requires either an active approach or an inactive approach. This issue was systematically investigated by comparing the effects of general action goals and general inaction goals on attitude change. As prior attitudes facilitate preparation for an upcoming persuasive message, general action goals were hypothesized to facilitate conscious retrieval of prior attitudes and therefore hinder attitude change to a greater extent than general inaction goals. Experiment 1 demonstrated that action primes (e.g., "go," "energy") yielded faster attitude report than inaction primes (e.g., "rest," "still") among participants who were forewarned of an upcoming persuasive message. Experiment 2 showed that the faster attitude report identified in Experiment 1 was localized on attitudes toward a message topic participants were prepared to receive. Experiments 3, 4, and 5 showed that, compared with inaction primes, action primes produced less attitude change and less argument scrutiny in response to a counterattitudinal message on a previously forewarned topic. Experiment 6 confirmed that the effects of the primes on attitude change were due to differential attitude retrieval. That is, when attitude expression was induced immediately after the primes, action and inaction goals produced similar amounts of attitude change. In contrast, when no attitude expression was induced after the prime, action goals produced less attitude change than inaction goals. Finally, Experiment 7 validated the assumption that these goal effects can be reduced or reversed when the goals have already been satisfied by an intervening task.     

The Short Nicotine Dependence Syndrome Scale (NDSS-S) in Spanish smokers

We present a brief scale derived from the Nicotine Dependence Syndrome Scale (NDSS). We used a sample of 1.061 daily smokers, which was obtained from five Primary Care Health Centers, a Unit of Alcoholism, and a Smoking Cessation Unit. All smokers were evaluated with the NDSS and the SCID to assess nicotine dependence according to DSM-IV criteria. The results indicate the existence of a general factor of nicotine dependence according to the NDSS. We selected the items with a higher factor loading (>.50), obtaining a short scale of 6 items. With this brief scale, we obtained results similar to those of the total scale in the diverse variables (sociodemographic and smoking) of the study. Scale reliability is satisfactory (a= .79), the correlation between the short and the total scale is very high (r=.95, p<.001) and the short scale discriminates the smokers in terms of cigarette consumption and nicotine dependence, as assessed with the SCID. The operation under the ROC curve is excellent (area under the curve .84). The data indicate the usefulness of this brief scale (NDSS-S) to assess nicotine dependence in smokers.     

Interactions between intrinsic principles of similarity and proximity and extrinsic principle of common region in visual perception

The interactions between intrinsic grouping principles (by proximity or by similarity in shape or luminance) and extrinsic grouping by common region were examined by presenting both principles acting alone or conjoined with another principle in visual patterns. The procedure used in our study closely mirrored that of Quinlan and Wilton (1998 Perception 27 417-430). However, in the present experiment, the intrinsic and extrinsic grouping principles involved had similar relative salience in order to avoid their possible effects on interactions. The results showed that the grouping effect of conjoined cooperating principles was greater than that of either principle acting alone, and the grouping effect of conjoined competing principles was lower than that of either principle operating alone. Compatibility of data with additive effects of grouping principles has been examined.     

Social perception of the Spanish law for young offenders

The implementation of the law 5/2000 for the regulation of Criminal Responsibility for Minors has led to a change in interventions in cases of juvenile offenders. This law promotes the educational and rehabilitative aims of the measures imposed. However, the focus of the media on the most serious cases has generated considerable alarm in society in general. The aim of this study is to determine the social perception of Law 5/2000. For this purpose, a sample of 936 people from the Autonomous Region of the Canary Islands was surveyed. The main results indicate that there is a significant lack of knowledge about the law and that people tend to think that the measures taken are not as effective as studies carried out in connection with this subject have shown. Nevertheless, the people surveyed are more in favour of educational measures than of measures that penalize. These results are discussed in connection with the importance that community factors have in dealing with juvenile delinquency, and in particular, in the power of social pressure to modify legislation, and of the community to assume responsibility for the reinsertion of juvenile offenders.     

Use of multilevel logistic regression to identify the causes of differential item functioning

Given that a key function of tests is to serve as evaluation instruments and for decision making in the fields of psychology and education, the possibility that some of their items may show differential behaviour is a major concern for psychometricians. In recent decades, important progress has been made as regards the efficacy of techniques designed to detect this differential item functioning (DIF). However, the findings are scant when it comes to explaining its causes. The present study addresses this problem from the perspective of multilevel analysis. Starting from a case study in the area of transcultural comparisons, multilevel logistic regression is used: 1) to identify the item characteristics associated with the presence of DIF; 2) to estimate the proportion of variation in the DIF coefficients that is explained by these characteristics; and 3) to evaluate alternative explanations of the DIF by comparing the explanatory power or fit of different sequential models. The comparison of these models confirmed one of the two alternatives (familiarity with the stimulus) and rejected the other (the topic area) as being a cause of differential functioning with respect to the compared groups.
