Sequence learning under dual-task conditions: alternatives to a resource-based account

In two experiments with the serial reaction-time task, participants were presented with deterministic or probabilistic sequences under single- or dual-task conditions. Experiment 1 showed that learning of a probabilistic structure was not impaired over a first session by performing a counting task, but that such an interference arose over a second session, when the knowledge was tested under single-task conditions. In contrast, the effects of the secondary task arose earlier for participants exposed to deterministic sequences. This difference between deterministic and probabilistic sequences disappeared in Experiment 2, where the counting task was performed on tones associated to the locations. Comparisons between sessions indicated that the secondary task affected not only the expression but also the acquisition of sequence learning, and that greater interference was observed in those conditions that yielded more explicit knowledge. These results suggest that the effects of a dual task on the measures of implicit sequence learning may be partly due to the intrusion of explicit knowledge and partly due to the disruption of the sequence produced by the inclusion of random events.     

Religious Experience Reconsidered as an example of theoretical assertiveness in the study of religion

The publication of Religious Experience Reconsidered is one more indication that the incoherent mixture of coyness and braggadocio that for decades has characterized the study of religion and other disciplines, is finally giving way to honest theoretical assertiveness. Taves’ book is a careful treatment of experience deemed religious that manages to do justice to the recurrent features of what people tend to experience in such contexts, while also taking into consideration the culture-bound components of those experiences. What is especially welcome is that instead of seeking to establish a bland middle ground, she has pursued an independent path, making use of scholarship in a variety of disciplines, especially psychology of religion.     

Modulation of the leniency bias in the discursive dilemma

We experimentally approach the discursive dilemma to gain insight into people's procedural appropriateness judgments. We relied on a vignette in which three people had formed opinions about two skills (premises) of a candidate to decide whether to hire her/him (conclusion). The dilemma arises when different outcomes (hire vs. not hire) are achieved depending on whether the majority opinion is independently considered for each premise or for the global conclusion of each judge. Participants were asked to choose the procedure they thought to be more appropriate to reach a decision. In Experiment 1, we found a leniency effect (a bias to prefer the aggregation procedure that led to hiring the candidate), which was reduced by introducing the participant as a juror with an exogenously provided negative opinion about the candidate's skills. In Experiment 2, we replicated the opinion effect, even when subjects did not participate as jury members. In Experiment 3, we found that the leniency bias was only reduced when participants' negative opinion was aligned with a majority of negative premises, but not with a majority of negative conclusions. We discuss present findings in terms of the identification of empirical regularities that may affect people's procedural legitimacy judgments.     

Implicit sequence learning in a search task

This study investigated the effects of selection demands on implicit sequence learning. Participants in a search condition looked for a target among seven distractors and responded on the target identity. The responses followed a deterministic sequence, and sequence learning was compared to that found in two control conditions in which the targets were presented alone, either at a central location or over a series of unpredictable locations. Sequence learning was obtained in all conditions, and it was equivalent for the two variable location conditions, regardless of the perceptual demands. Larger effects of learning were observed in the central location, both on the indirect measures and on the measures taken from a cued-generation task. The expression of learning decreased selectively in this condition when the sequence validity was reduced over a test block. These results are consistent with the claims that implicit and explicit learning are mixed in this central condition and that implicit learning is not affected by selection difficulty.     

Do Bilinguals Automatically Activate Their Native Language When They Are Not Using It?

Most models of lexical access assume that bilingual speakers activate their two languages even when they are in a context in which only one language is used. A critical piece of evidence used to support this notion is the observation that a given word automatically activates its translation equivalent in the other language. Here, we argue that these findings are compatible with a different account, in which bilinguals “carry over” the structure of their native language to the non‐native language during learning, and where there is no activation of translation equivalents. To demonstrate this, we describe a model in which language learning involves mapping native language phonological relationships to the non‐native language, and we show how it can explain the results attributed to automatic activation of translation equivalents.     

If Bill Clinton Were a Woman: The Effectiveness of Male and Female Politicians' Account Strategies Following Alleged Transgressions

As persons whose careers depend upon the support of the public, politicians by definition are required to be concerned with the management of their public impressions. This research considers the impact of a politician's sex on citizens' evaluations following alleged transgressions. The study uses an experimental design to test how the sex of the politician affects the acceptability of various accounts following transgressions. The interaction of sex with the nature of the offense and the type of account offered is examined. Analysis suggests that sex, type of account, and type of transgression affect citizens' evaluations although not always in obvious or direct ways. Most significantly, the analysis shows that women are not judged more harshly than men when involved in a transgression.     

The socialization of prosocial behavioral tendencies among Mexican American adolescents: The role of familism values

This study investigates the role of familism values in fostering socialization experiences that promote prosocial behavioral tendencies among Mexican American adolescents. Two hundred and four Mexican American mothers and their adolescent children (104 girls, age M = 10.91 years) completed measures of familism values, prosocial parenting practices, and prosocial behavioral tendencies. Structural equation modeling tests indicated that mothers' familism values are related to parenting behaviors that promote prosocial behavioral tendencies, which in turn are related to adolescents' perception of prosocial parenting practices. Furthermore, adolescents' perception of prosocial parenting practices is related to familism values and prosocial behavior tendencies. Last, the relation between adolescents' perception of prosocial parenting practices and prosocial behavioral tendencies is partially mediated by familism values. These findings are consistent with the theoretical suggestion that the transmission of traditional familism values may serve as a social medium through which prosocial behavioral tendencies are fostered among Mexican American adolescents.     

Prosocial development in early adulthood: a longitudinal study

Consistency of measures of a prosocial personality and prosocial moral judgment over time, and the interrelations among them, were examined. Participants and friends' reports of prosocial characteristics were obtained at ages 21-22, 23-24, and 25-26 years. In addition, participants' prosocial judgment was assessed with interviews and with an objective measure of prosocial moral reasoning at several ages. Reports of prosocial behavior and empathy-related responding in childhood and observations of prosocial behavior in preschool also were obtained. There was interindividual consistency in prosocial dispositions, and prosocial dispositions in adulthood related to empathy/sympathy and prosocial behavior at much younger ages. Interview and objective measures of moral reasoning were substantially interrelated in late adolescence/early adulthood and correlated with participants' and friends' reports of a prosocial disposition.     

Five Observations Concerning the Intended Meaning of the Intuitionistic Logical Constants

This paper contains five observations concerning the intended meaning of the intuitionistic logical constants: (1) if the explanations of this meaning are to be based on a non-decidable concept, that concept should not be that of `proof"; (2) Kreisel"s explanations using extra clauses can be significantly simplified; (3) the impredicativity of the definition of can be easily and safely ameliorated; (4) the definition of in terms of `proofs from premises" results in a loss of the inductive character of the definitions of and and (5) the same occurs with the definition of in terms of `proofs with free variables".
