The Time-Course of Metaphor Comprehension: An Event-Related Potential Study

ERPs were recorded while subjects were reading short familiar metaphors (e.g., Those fighters are lions), unfamiliar metaphors (Those apprentices are lions), or literal control sentences (Those animals are lions) presented in isolation or preceded by either an irrelevant or relevant context (e.g., They are not idiotic: . . . .” vs. “They are not cowardly: Those fighters are lions”). The terminal word of metaphors elicited larger N400 components than did the terminal word of literal sentences (Experiment 1) suggesting that the (incongruous) literal meaning of metaphors was indeed accessed at some point during comprehension. The analysis of the 600–1000 and 1000–1400 latency bands (Late Positive Components) revealed no significant difference between metaphors and literal sentences. The manipulation of metaphor difficulty (Experiments 2 and 3) also failed to reveal any late effect specifically linked to metaphorical processing. Finally, an effect of the preceding sentence context was found in Experiments 3 and 4, as early as 300 ms following the terminal word onset. Overall, these results support a context-dependent account of metaphor comprehension stating that when contextually relevant, the metaphorical meaning is the only one accessed.     

The gender-marking effect in spoken word recognition

In this paper we examine whether the recognition of a spoken noun is affected by the gender marking—masculine or feminine—that is carried by a preceding word. In the first of two experiments, the gating paradigm was used to study the access of French nouns that were preceded by an appropriate gender marking, carried by an article, or preceded by no gender marking. In the second experiment, subjects were asked to make a lexical decision on the same material. A very strong facilitatory effect was found in both cases. The origin of the gender-marking effect is discussed, as well as the level of processing involved—lexical or syntactic.     

Divided attention between lyrics and tunes of operatic songs: Evidence for independent processing

Excerpts from French operatic songs were used to evaluate the extent to which language and music compete for processing resources. Do these two dimensions conflict? Are they integrated into a single percept? Or are they independent? The final word of each excerpt was either semantically congruous or incongruous relative to the prior linguistic context and was sung either in or out of key. Participants were asked to detect either the semantic or the melodic incongruity (single task) or both (dual task). We predicted a dual-task deficit if these tasks conflicted and no deficit if they were either independent or integrated. In order to distinguish between these last two outcomes, trial-by-trial contingency analyses were also computed, predicting no correlation if the tasks were conflicting or independent, a positive correlation under the assumption of integration and a negative correlation if dividing attention is impossible. Our results show similar levels of performance in single and dual tasks and no correlation between dual-task judgments, thus suggesting that semantic and melodic aspects of language are processed by independent systems. In addition, a comparison between musicians and nonmusicians shows that these conclusions are independent of musical expertise.     

Bridging novelty and familiarity-based recognition memory: A matter of timing

Novelty detection is essential to adapt to changes. However, the relationship between novelty detection and visual recognition memory remains unclear. To characterize the temporal dynamics of novelty and its connection to familiarity, we probed early behavioural performance of novelty and familiarity in 31 participants using a speeded go/no-go recognition task with a 600-ms response deadline. Responses to familiarity and novelty produced symmetrical biases and correlated accuracies and biases, but novelty decisions were less accurate and had slower minimal reaction times (410?ms). These processes thus appear to be independent, as suggested by a more efficient system in the case of familiarity, but with common factors bringing overlapping contributions to both processes. This may possibly be explained by the more fluent processing of repeated stimuli, but with familiarity and novelty potentially relying on one decision criterion, as suggested by the correlated and remarkably symmetrical biases. This study supports models that conceptualize novelty and familiarity decisions as two partly overlapping processes.     

Predicting workplace aggression: a meta-analysis

The authors conducted a meta-analysis of 57 empirical studies (59 samples) concerning enacted workplace aggression to answer 3 research questions. First, what are the individual and situational predictors of interpersonal and organizational aggression? Second, within interpersonal aggression, are there different predictors of supervisor- and coworker-targeted aggression? Third, what are the relative contributions of individual (i.e., trait anger, negative affectivity, and biological sex) and situational (i.e., injustice, job dissatisfaction, interpersonal conflict, situational constraints, and poor leadership) factors in explaining interpersonal and organizational aggression? Results show that both individual and situational factors predict aggression and that the pattern of predictors is target specific. Implications for future research are discussed.     

Strategy switch costs in arithmetic problem solving

Three experiments tested whether switching between strategies involves a cost. In three experiments, participants had to give approximate products to two-digit multiplication problems (e.g., 47×76). They were told which strategy to use (Experiments 1 and 2) or could choose among strategies (Experiment 3). The participants showed poorer performance when they used different strategies on two consecutive trials than when they used the same strategy. They also used the same strategy over two consecutive problems more often than they used different strategies. These effects, termed strategy switch costs, were found when the participants executed the easiest strategy and when they solved easy problems. We discuss possible processes underlying these strategy switch costs and the implications of these strategy switch costs for models of strategy choices.     

Singing in the Brain: Independence of Lyrics and Tunes

Why is vocal music the oldest and still the most popular form of music? Very possibly because vocal music involves an intimate combination of speech and music, two of the most specific, high-level skills of human beings. The issue we address is whether people listening to a song treat the linguistic and musical components separately or integrate them within a single percept. Event-related potentials were recorded while musicians listened to excerpts from operas sung a capella. Excerpts were ended by semantically congruous or incongruous words sung either in or out of key. Results clearly demonstrated the independence of lyrics and tunes, so that an additive model of semantic- and harmonic-violations processing predicted the data extremely well. These results are consistent with a modular organization of the human cognitive system and open new perspectives in the search for the similarities and differences between language and music processing.     

Parental autonomy-supportive practices and toddlers’ rule internalization: A prospective observational study

Motivational research conducted within self-determination theory suggests that autonomy-supportive (AS) parenting fosters rule internalization, while more controlling tactics hinder it. The goal of the present study is to examine how AS in a socialization context relates to toddlers’ internalization. Toddlers participated in a clean-up and a toy prohibition task at 2 and 3.5 years of age (T1: N?=?102; T2: N?=?85). Their parent’s disciplinary strategies were coded the first year. Toddlers’ committed compliance, indicative of rule internalization, was coded at both time points. After controlling for covariates and initial committed compliance, a linear regression was conducted to predict change in committed compliance over time. As expected, results reveal that parental AS strategies when toddlers were 2 years old were positively related to an improvement in committed compliance from 2 to 3.5 years of age, while controlling strategies predicted deterioration. This prospective, observational study suggests that supporting toddlers’ autonomy in socialization contexts fosters rule internalization.
