There is no clam with coats in the calm coast: Delimiting the transposed-letter priming effect

In this article, we explore the transposed-letter priming effect (e.g., jugde–JUDGE vs. jupte–JUDGE), a phenomenon that taps into some key issues on how the brain encodes letter positions and has favoured the creation of new input coding schemes. However, almost all the empirical evidence from transposed-letter priming experiments comes from nonword primes (e.g., jugde–JUDGE). Indeed, previous evidence when using word–word pairs (e.g., causal–CASUAL) is not conclusive. Here, we conducted five masked priming lexical decision experiments that examined the relationship between pairs of real words that differed only in the transposition of two of their letters (e.g., CASUAL vs. CAUSAL). Results showed that, unlike transposed-letter nonwords, transposed-letter words do not seem to affect the identification time of their transposed-letter mates. Thus, prime lexicality is a key factor that modulates the magnitude of transposed-letter priming effects. These results are interpreted under the assumption of the existence of lateral inhibition processes occurring within the lexical level—which cancels out any orthographic facilitation due to the overlapping letters. We examine the implications of these findings for models of visual-word recognition.     

Coding categorical and coordinate spatial relations in visual–spatial short-term memory

Four experiments explored the coding of categorical and coordinate spatial relations in visual–spatial short-term memory (VSSTM). Participants judged whether two stimuli presented successively on a computer screen were the same or different. On positional change trials the two stimuli differed in the position of one element. Positional changes were of two types, coordinate and categorical. On coordinate trials the position of one element changed by a small amount, but retained the categorical relationships (above, below, left of, right of) to all other elements. On categorical trials one element moved by the same amount but additionally changed its categorical relationship to one of the other elements (e.g., changed from below to above). Participants detected categorical changes more accurately than coordinate changes when the elements were independent locations marked by squares, indicating that the categorical relationships amongst the squares were encoded in memory. Furthermore, this categorical advantage was unmodulated by either the suppression of articulation (Experiment 2) or by the requirement to retain either colour–position associations or positions only (Experiment 3). When the elements to be remembered were the vertices of simple outline polygons (Experiment 4) there was no categorical advantage, establishing the effect as spatial in nature. Contrary to predictions derived from Postma and De Haan (1996) Postma, A. and De Haan, E. H. 1996. What was where? Memory for object locations. Quarterly Journal of Experimental Psychology, 49A: 178–199. [Crossref], [Web of Science ®] , [Google Scholar], the employment of categorical relations appears not to be specifically linked to either verbal coding or to the requirement to associate objects with positions. The results suggest that the categorical relations are an intrinsic property of the representation of spatial configurations.     

Are transposition effects specific to letters?

Recent research has consistently shown that pseudowords created by transposing two letters are perceptually similar to their corresponding base words (e.g., jugde–judge). In the framework of the overlap model (Gomez, Ratcliff, & Perea, 2008), this effect is due to a noisy process in the localization of the “objects” (e.g., letters, kana syllables). In the present study, we examine whether this effect is specific to letter strings or whether it also occurs with other “objects” (namely, digits, symbols, and pseudoletters). To that end, we conducted a series of five masked priming experiments using the same–different task. Results showed robust effects of transposition for all objects, except for pseudoletters. This is consistent with the view that locations of familiar objects (i.e., letters, numbers, and symbols) can be best understood as distributions along a dimension rather than as precise points.     

No deficiency in left-to-right processing of words in dyslexia but evidence for enhanced visual crowding

Whitney and Cornelissen hypothesized that dyslexia may be the result of problems with the left-to-right processing of words, particularly in the part of the word between the word beginning and the reader's fixation position. To test this hypothesis, we tachistoscopically presented consonant trigrams in the left and the right visual field (LVF, RVF) to 20 undergraduate students with dyslexia and 20 matched controls. The trigrams were presented at different locations (from –2.5° to?+?2.5°) in both visual half fields. Participants were asked to identify the letters, and accuracy rates were compared. In line with the predictions of the SERIOL (sequential encoding regulated by inputs to oscillations within letter units) model of visual word recognition, a typical U-shaped pattern was found at all retinal locations. Accuracy also decreased the further away the stimulus was from the fixation location, with a steeper decrease in the LVF than in the RVF. Contrary to the hypothesis, the students with dyslexia showed the same pattern of results as did the control participants, also in the LVF, apart from a slightly lower accuracy rate, particularly for the central letter. The latter is in line with the possibility of enhanced crowding in dyslexia. In addition, in the dyslexia group but not in the control group the degree of crowding correlated significantly with the students’ word reading scores. These findings suggest that lateral inhibition between letters is associated with word reading performance in students with dyslexia.     

A Defining Presidential Moment: 9/11 and the Rally Effect

Public approval ratings of George W. Bush surged after the 11 September 2001 terrorist attacks. This study used a quasi–experimental, within–respondents design to investigate the relative contribution of five factors to this classic rally effect: the stimulus event itself, Bush's speech that evening, media exposure, partisan support, and gender effects. Respondents were pretested on the morning of the attacks; one group was posttested immediately after the speech, another group 41 hours later. Stability of effects was examined through an additional study of Bush's 20 September 2001 speech to a joint session of Congress. The findings indicate that Bush's 11 September speech was the critical factor in this rally effect; none of the other factors contributed significantly.     

Cognitive Skills as Predictor of Attitudes Toward Political Conflict: A Study of Polish Politicians

The relationship between cognitive development and attitudes toward a current political conflict was examined in a sample of 46 Polish politicians. This relationship was examined in a control group in a neutral condition and in an experimental group after participants were presented with a hostile attack on their position on the conflict. Politicians with less advanced cognitive skills tended to use competitive attitudes in both conditions. In contrast, those who possessed more advanced skills tended to use cooperative attitudes in the neutral situation; after the emotional attack, they tended to avoid further involvement in the conflict and sought to exit it. The key difference in participants' cognitive functioning was their ability to differentiate perspectives and to transcend their own point of view in the conflict.     

Authoritarianism and Political Impoverishment: Deficits in Knowledge and Civic Disinterest

Past research shows that authoritarian individuals hold strong opinions about a variety of political and social issues, such as race relations and military conflict. What has not been established, though, is the amount of general political knowledge that authoritarians possess. In this study, three groups of college students were administered Altemeyer's Right-Wing Authoritarianism (RWA) scale; most of them also received items assessing general political knowledge and specific knowledge about the 2000 presidential election, as well as items assessing interest in politics. Relative to students with low RWA scores, those with high scores possessed less political knowledge; moreover, they expressed less interest in learning about politics. In general, authoritarianism was unrelated to how individuals got their political information or how credible they found their sources. The implication that authoritarians hold strong attitudinal beliefs with weak political knowledge is discussed.     

Gratitude and Good Government

I attempt to show that it is notphilosophically incompetent to ground politicalobligation in feelings of gratitude. But theargument needs to be stated carefully.Gratitude must be distinguished fromreciprocity. It applies only to good governmentwhich provides benefits to citizens for whichthey ought to feel grateful. It applies only tocitizens who accept that their feelings ofgratitude are properly demonstrated by anacceptance on their part of the duties ofcitizenship. It does not apply to citizenswhose benefits are purchased at the expense ofthe unjust treatment of fellow citizens.

Is Political Cognition Like Riding a Bicycle? How Cognitive Neuroscience Can Inform Research on Political Thinking

Our understanding of political phenomena, including political attitudes and sophistication, can be enriched by incorporating the theories and tools of cognitive neuroscience—in particular, the cognitive neuroscience of nonconscious habitual cognition (akin to bicycle riding). From this perspective, different types of informational "building blocks" can be construed from which different types of political attitudes may arise. A reflection-reflexion model is presented that describes how these blocks combine to produce a given political attitude as a function of goals, primes, expertise, and inherent conflict in considerations relevant to the attitude. The ways in which neuroimaging methods can be used to test hypotheses of political cognition are reviewed.
