Entrevista con Michael Cole

RESUMEN

Michael Cole es profesor en los departamentos de psicología y comunicaciones de la Universidad de California, San Diego (UCSD). Puede considerarse que el profesor Cole es hoy una de las figuras más interesantes en el panorama de la psicología norteamericana y, uno de los responsables más destacados de la difusión y ampliación de la escuela vygotskiana en Estados Unidos. En esta entrevista el profesor Cole reflexiona sobre las premisas de su visión de la psicología de la cultura y la comunicación, las relaciones entre la ciencia y la sociedad y otros problemas fundamentales de la psicología contemporánea, además de hacer un breve recorrido por su historia de formación como psicólogo tanto en Estados Unidos como en su etapa en la Unión Soviética.     

Authentic leadership and its relationships with work engagement and organizational citizenship behaviors in military units: The role of identification as a mediating variable

The objective of the study is to explore the relationship of authentic leadership with work engagement and organizational citizenship behaviors (OCB) in military units, measuring the mediating effect of personal identification with the leader and social identification with the military unit. We used the Structural Equation Modeling (SEM) technique to analyze data from a sample of 225 Spanish military troops. The results showed that social identification with the military unit influenced the relationship of authentic leadership with the outcome variables.     

Examining the relation between ratings of executive functioning and academic achievement: Findings from a cross-cultural study

The present study investigated the relation between academic performance and ratings of executive functioning in children aged 6–11 from four countries: Sweden, Spain, Iran, and China. Ratings of executive functioning were made by both parents and teachers using the Childhood Executive Functioning Inventory (CHEXI). The results showed that the Chinese sample was generally rated as having more executive deficits compared to the other samples. The finding that executive functioning deficits are exacerbated in China is most likely the result of cultural biases. Boys were generally rated as having poorer executive functioning compared to girls, except in Iran where parents, but not teachers, rated girls as having poorer executive functioning compared to boys. However, this opposite pattern of results found for Iran is not likely to reflect true gender differences in executive functioning. Despite some differences in the levels of executive functioning across countries, both the inhibition and working memory subscales of the CHEXI were related to academic achievement in all four countries, except for CHEXI parent ratings in China. Altogether, the results indicate that the CHEXI may be used as a screening measure for early academic difficulties, although cultural biases clearly have to be taken into consideration.     

Kant on Truth-Aptness

Many scholars claimed that, according to Immanuel Kant, some judgements lack a truth-value: analytic judgements, judgements about items of which humans cannot have experience, judgements of perception, and non-assertoric judgements. However, no one has undertaken an extensive examination of the textual evidence for those claims.

Based on an analysis of Kant's texts, I argue that: ? according to Kant, only judgements of perception are not truth-apt. All other judgements are truth-apt, including analytic judgements and judgements about items of which humans cannot have experience.

? Kant sometimes states that truth-apt judgements are actual bearers of truth or falsity only when they are taken to state what is actually the case. Kant calls these judgements assertoric. Other texts ascribe truth and falsity to judgements, regardless of whether they are assertoric.

Kant's views on truth-aptness raise challenges for correspondentist and coherentist interpretations of Kant's theory of truth; they rule out the identification of Kant's crucial notion of objective validity with truth-aptness; and they imply that Kant was not a verificationist about truth or meaning.     

The simplest chronoscope II: reaction time measured by meterstick versus machine

Visual simple reaction time (SRT) scores measured in 31 college students of both sexes by use of the simplest chronoscope methodology (meterstick SRT) were compared to scores obtained by use of an electromechanical multi-choice reaction timer (machine SRT). Four hypotheses were tested. Results indicated that the previous mean value of meterstick SRT was replicated; meterstick SRT was significantly faster than long-standing population estimates of mean SRT; and machine SRT was significantly slower than the same long-standing mean SRT estimates for the population. Also, the mean meterstick SRT of 181 msec. was significantly faster than the mean machine SRT of 294 msec. It was theorized that differential visual information processing occurred such that the dorsal visual stream subserved meterstick SRT; whereas the ventral visual stream subserved machine SRT.     

Direct contact as a moderator of extended contact effects: cross-sectional and longitudinal impact on outgroup attitudes, behavioral intentions, and attitude certainty

Cross-group friendships (the most effective form of direct contact) and extended contact (i.e., knowing ingroup members who have outgroup friends) constitute two of the most important means of improving outgroup attitudes. Using cross-sectional and longitudinal samples from different intergroup contexts, this research demonstrates that extended contact is most effective when individuals live in segregated neighborhoods having only few, or no, direct friendships with outgroup members. Moreover, by including measures of attitudes and behavioral intentions the authors showed the broader impact of these forms of contact, and, by assessing attitude certainty as one dimension of attitude strength, they tested whether extended contact can lead not only to more positive but also to stronger outgroup orientations. Cross-sectional data showed that direct contact was more strongly related to attitude certainty than was extended contact, but longitudinal data showed both forms of contact affected attitude certainty in the long run.     

The effectiveness of intergroup contact at work: Mediators and moderators of hospital workers' prejudice towards immigrants

The present research examines the effectiveness of intergroup contact between 167 Italian hospital workers and foreign patients in reducing prejudice towards immigrants in general. The outcomes of contact at work were analysed controlling for the influence of contact outside the workplace and through mass media, and taking into account the role of empathy, anxiety and group membership salience. Results indicate that the beneficial effects of contact at work were partially mediated by increased empathy and reduced anxiety, experienced both in the work environment and towards immigrants in general. Finally, high levels of group membership salience facilitated the influence of contact on intergroup emotions. These findings show that contact at work can be a powerful means to reduce prejudice, thanks to its capacity to evoke changes in affective responses. Copyright © 2010 John Wiley & Sons, Ltd.     

The contribution of prefixes to morphological processing of Spanish words

Three series of priming experiments were conducted to probe the morphological and phonological contributions to visual word recognition in Spanish. Prefixed, e.g., INCAPAZ (incapable), and pseudoprefixed, e.g., INDUSTRIA (industry) target words were presented for recognition following a prefixed, e.g., infeliz (unhappy), or pseudoprefixed, e.g., insulto (insult), prime starting with the same syllable as the target, at masked short or long stimulus onset asynchronies (SOAs). At long SOAs the recognition of prefixed targets was facilitated by prefixed primes and inhibited by pseudoprefixed ones, whereas both prefixed and pseudoprefixed primes facilitated the recognition at short SOAs. In contrast, the recognition of pseudoprefixed targets was unaffected by the kind of prime presented, even when we used pairs of words overlapping in syllables that cannot be prefixes in Spanish. These results support a special status for morphological elements in access to meaning in reading.     

Effects of Decision Training on Decision Making and Performance in Young Tennis Players: An Applied Research

This study examined the effectiveness of a 10-week decision training program on decision making and performance in tennis. Decision training was based on the analysis combining tactical questioning and video feedback about players own actions. A quasi-experimental design with intermediate tennis players (control group, n = 6; experimental group, n = 5) was developed over 18 weeks, divided into 3 phases: preintervention, postintervention, and retention. A total of 13,383 game play actions were analyzed to test differences. Experimental group improves significantly decision making and performance and maintained improvements during the retention phase. Video feedback combined with questioning is recommended to achieve sport expertise.
