The role of number words: the phonological length effect in multidigit addition

We explored the role of phonological representations of number words in exact calculation. The reaction times and accuracy of responses in multidigit addition problems were compared across three groups of participants (young healthy, older healthy, and 3 patients with severe aphasia) and two types of addition problems: phonologically long in English (containing the bisyllabic number word ??seven??) and short in English (monosyllabic number words??e.g., ??six??). Older healthy participants were significantly faster and more accurate in calculation than younger healthy participants. The older participants showed no evidence of a phonological length effect. However this effect was apparent in the younger adults, with longer reaction times on phonologically long problems. Furthermore, there was an association between the presence of a phonological length effect and the overall speed of response, suggesting that less proficient calculators were more reliant on phonological mediation of performance. The aphasic participants retained the ability to complete multidigit additions and were as accurate as the younger healthy group, although the response times of two of the 3 patients were slow. The aphasic participants varied with regard to the presence of a phonological length effect. Two participants showed no evidence of phonological mediation, while 1 displayed a phonological length effect. The results suggest that language resources are not mandatory for exact addition, although they may be used to scaffold math performance in less competent calculators. Evidence of phonological mediation of performance in aphasic participants may provide insight into the integrity or otherwise of inner speech in severe aphasia.     

Reading acquisition enhances an early visual process of contour integration

The acquisition of reading has an extensive impact on the developing brain and leads to enhanced abilities in phonological processing and visual letter perception. Could this expertise also extend to early visual abilities outside the reading domain? Here we studied the performance of illiterate, ex‐illiterate and literate adults closely matched in age, socioeconomic and cultural characteristics, on a contour integration task known to depend on early visual processing. Stimuli consisted of a closed egg‐shaped contour made of disconnected Gabor patches, within a background of randomly oriented Gabor stimuli. Subjects had to decide whether the egg was pointing left or right. Difficulty was varied by jittering the orientation of the Gabor patches forming the contour. Contour integration performance was lower in illiterates than in both ex‐illiterate and literate controls. We argue that this difference in contour perception must reflect a genuine difference in visual function. According to this view, the intensive perceptual training that accompanies reading acquisition also improves early visual abilities, suggesting that the impact of literacy on the visual system is more widespread than originally proposed.     

From Theory of Rhetoric to the Practice of Language Use: The Case of Appeals to Ethos Elements

In their book Commitment in Dialogue, Walton and Krabbe claim that formal dialogue systems for conversational argumentation are “not very realistic and not easy to apply”. This difficulty may make argumentation theory less well adapted to be employed to describe or analyse actual argumentation practice. On the other hand, the empirical study of real-life arguments may miss or ignore insights of more than the two millennia of the development of philosophy of language, rhetoric, and argumentation theory. In this paper, we propose a novel methodology for adapting such theories to serve as applicable tools in the study of argumentation phenomena. Our approach is both theoretically-informed and empirically-grounded in large-scale corpus analysis. The area of interest are appeals to ethos, the character of the speaker, building upon Aristotle’s rhetoric. Ethotic techniques are used to influence the hearers through the communication, where speakers might establish, but also emphasise, weaken or undermine their own or others’ credibility and trustworthiness. Specifically, we apply our method to Aristotelian theory of ethos elements which identifies practical wisdom, moral virtue and goodwill as components of speakers’ character, which can be supported or attacked. The challenges we identified in this case and the solutions we proposed allow us to formulate general guidelines of how to exploit rich theoretical frameworks to the analysis of the practice of language use.

Men in the Office,Women in the Kitchen? Contextual Dependency of Gender Stereotype Activation in Spanish Women

In a set of two studies, we tested whether gender-stereotypical associations are automatically activated by Spanish women in a categorization task, and how this process is conditioned by the context in which the target is presented (kitchen vs. office). We hypothesized that gender stereotypes would be activated implicitly when the target (men vs. women) appeared in an office context (associated with male dominant roles), but not when they appeared in a kitchen context (traditionally associated with female roles). The studies were conducted with two samples (N?=?44; N?=?47) of female undergraduate students from the University of Granada (Spain). In both studies, a priming effect was found, indicating that a traditional, role-congruent stereotype pattern (men-competence, women-warmth) emerged when primes appeared in an office context, but not in a kitchen context. Further, negative competence traits were evaluated faster when a male prime was presented in the context of a kitchen (role-incongruent). The purpose of Study 2 was to clarify the implicit nature of this contextual contingency effect by manipulating the controllability of the priming effect (i.e., Stimulus Onset Asynchrony duration-SOA, and restricted response time). The results of Study 1 were replicated in only the short SOA condition, which implies faster and presumably less controlled processing of the stimuli. Theoretical implications for stereotyping and gender role research are discussed.     

Limits of control: The effects of uncontrollability experiences on the efficiency of attentional control

Two experiments were conducted to explore the effects of experiencing uncontrollability on the efficiency of attentional control. The experience of uncontrollability was induced either by unsolvable tasks (Experiment 1) or by tasks in which non-contingent feedback was provided (Experiment 2). A version of the Attentional Network Test-Interactions with an additional measure of vigilance (ANTI-V) was used to evaluate the efficiency of the attentional networks (i.e., alerting, orienting, and executive). Results of both experiments revealed a decreased efficiency of executive attention in participants who experienced stable control deprivation but no negative effects in participants who were able to restore their sense of previously deprived control. Additionally, when participants were asked to perform unsolvable tasks and did not receive feedback (Experiment 1), detrimental effects on the orienting network and vigilance were observed. The motivational and cognitive mechanisms underlying the effects of various uncontrollability experiences on conflict resolution and attentional control are discussed.     

Motivational determinants of reasoning about social relations: The role of need for cognitive closure

The role of need for cognitive closure (NFCC) in reasoning about social relations was investigated. Participants learned pairwise liking/disliking relations between people who could also be categorised on the basis of nationality and then had to group them into social cliques. The social clique structures were either consistent or inconsistent with the nationality categorisation, and the diagnostic information that was necessary to determine the number of cliques appeared either early or late in the information sequence. We expected participants under conditions of high (vs low) NFCC to rely more on heuristic processing. As predicted, high (vs low) NFCC participants were less accurate in their representations of cliques when the clique structure was inconsistent with the nationality category (Study 1 and 2) and when the diagnostic information was presented late (Study 1). The implications regarding the influence of NFCC on reasoning and the role of specific NFCC manipulations are discussed.
