On the facilitatory effects of cognate words in bilingual speech production

There is a growing body of evidence showing that a word's cognate status is an important dimension affecting the naming performance of bilingual speakers. In a recent article, Kohnert extended this observation to the naming performance of an aphasic bilingual (DJ). DJ named pictures with cognate names more accurately than pictures with non-cognate names. Furthermore, having named the pictures in Spanish helped the subsequent retrieval (with a delay of one week between the two tests) of the same pictures' names in English, but only for pictures with cognate names. That is, there was a language transfer but only for those translation words that were phonologically similar. In this article we first evaluate the conclusions drawn from these results by Kohnert, and second we discuss the theoretical implications of the facilitatory effects of cognate words for models of speech production in bilingual speakers.     

Outcome additivity and outcome maximality influence cue competition in human causal learning

Recent research suggests that outcome additivity pretraining modulates blocking in human causal learning. However, the existing evidence confounds outcome additivity and outcome maximality. Here the authors present evidence for the influence of presenting information about outcome maximality (Experiment 1) and outcome additivity (Experiment 2) on subsequent forward blocking. The results of Experiment 3 confirm that, with outcome maximality controlled, outcome additivity affects backward blocking but not release from overshadowing. Finally, the results of Experiment 4 demonstrate that information about outcome additivity has a similar effect on forward blocking if presented after the blocking training instead of before. The results are compatible with the idea that blocking results from inferential processes at the time of testing and not from a failure to acquire associative strength during training.     

Acquired surface alexia in Spanish: a case report

This paper reports a case study of acquired surface alexia in Spanish and discusses the most suitable tests to detect this syndrome in a writing system that is very regular for reading at the segmental and supra-segmental levels. Patient MM has surface alexia characterized by quantitatively good performance in reading words and pseudowords; accurate but slow and syllabic reading of words, nonwords and sentences; good performance in lexical decision tasks including words and nonwords; errors in lexical decision with pseudohomophones; and homophone confusions. This pattern of reading can be interpreted as a disorder in the lexical reading route and overdependence on the non-lexical route. We discuss nonlexical impairments and the interpretation of alexia and suggest tasks to identify surface alexia in a shallow orthography.     

Orienting in space and time: Joint contributions to exogenous spatial cuing effects

We examined whether the time course of exogenous spatial-cuing effects is sensitive to the allocation of attention in time. Expectation for a target within a particular time window following the cue was manipulated by varying the proportion of trials that appeared at each of three stimulus onset asynchronies in both a detection task and a two-alternative forced-choice discrimination task. The time course of spatial-cuing effects was sensitive to the temporal expectation manipulation only in the discrimination task. The results are discussed with reference to the role of attentional set in exogenous spatialcuing paradigms.     

Overt head movements and persuasion: a self-validation analysis

The authors report 3 experiments that examine a new mechanism by which overt head movements can affect attitude change. In each experiment, participants were induced to either nod or to shake their heads while listening to a persuasive message. When the message arguments were strong, nodding produced more persuasion than shaking. When the arguments were weak, the reverse occurred. These effects were most pronounced when elaboration was high. These findings are consistent with the "self-validation" hypothesis that postulates that head movements either enhance (nodding) or undermine (shaking) confidence in one's thoughts about the message. In a 4th experiment, the authors extended this result to another overt behavior (writing with the dominant or nondominant hand) and a different attitude domain (self-esteem).     

Real-Time Processing Implications of Enriched Composition at the Syntax–Semantics Interface

This study reports results on the real-time consequences of aspectual coercion. We define aspectual coercion as a combinatorial semantic operation requiring computation over and above that provided by combining lexical items through expected syntactic processes. An experiment is described assessing whether or not parsing of a string requiring coercion—in addition to syntactic composition—is more computationally costly than parsing a syntactically transparent counterpart, a string that provides for an interpretable representation via syntactic composition alone. The prediction of a higher computational cost for this process is borne out by the results.     

Psychometric appraisal of Eysenck's revised Psychoticism scale: a cross-cultural study

Psychometric characteristics of Eysenck's revised P scale were studied in a cross-cultural research. The Spanish version of the Eysenck Personality Questionnaire-Revised (EPQ-R) was administered to a Spanish sample of 527 males and 583 females. Maximum-likelihood factor analyses of the item intercorrelations and Direct Oblimin rotations of the extracted factors were carried out separately for males and females. The results revealed four factors identified as psychoticism (P), extraversion (E), neuroticism (N) and dissimulation/conformity (L). Internal consistency and test–retest reliability coefficients were satisfactory and very similar to the ones found in the original study. Skewness and kurtosis of the P scale distribution were closer to normal than on the original British revised P scale.     

The effects of practice on object-based, location-based, and static-display inhibition of return

We report two experiments that examine the effects of practice on object-based, location-based, and static-display inhibition of return (IOR). The results are clean All three effects get smaller with practice. These findings are at odds with the results of Müller and von Mühlenen (1996), who failed to observe object-based IOR and detected no effect of practice on static-display IOR. However, their subjects were more practiced than ours prior to data collection. We suggest, therefore, that the reducing effect of practice on IOR might have occurred in their unrecorded practice sessions. We also discuss a two-process model in which IOR is seen as the net effect of underlying inhibitory and excitatory processes. In such models (e.g., Solomon & Corbit,1974), practice often results in a reduction of the net effect of the two processes.
