Phonological and semantic priming: Evidence for task-independent effects

The questions asked in the present experiments concern the generality of semantic and phonological priming effects: Do these effects arise automatically regardless of target task, or are these effects restricted to target tasks that specifically require the retrieval of the primed information? In Experiment 1, subjects produced faster color matching times on targets preceded by a masked rhyming prime than on targets preceded by an orthographic control or an unrelated prime. This result suggests that automatic priming effects on the basis of phonological similarity can be obtained even when the target task does not make use of phonological information. This claim was reinforced in Experiment 2 in which a rhyme priming effect and a semantic priming effect were found in a semantic categorization task. In Experiment 3, the target task was phonological (rhyme detection), and, again, both phonological and semantic priming effects were observed. Finally, in Experiments 4 and 5, in a replication and an extension of Experiment 1, phonological and semantic priming effects were found in a color matching task, a task involving neither phonological nor semantic processing. These results are most straightforwardly interpreted by assuming that both semantic and phonological priming effects are, at least in part, due to automatic activation of memorial representations.     

Peer violence in the School Environment and Its Relationship with Subjective Well-Being and Perceived Social Support Among Children and Adolescents in Northeastern Brazil

The general aim of this study was to analyse the relationship between peer violence in the school environment (bullying), subjective well-being and perceived social support from the perspective of 910 children and adolescents in Years 6 and 7 of primary school (M = 11.90 years old; SD = 1.21). The participants were taken from 27 primary schools—both state-run and private, urban and rural—in Cearà state (Brazil). The following instruments were used: the Peer Victimization and Aggression Scale (EVAP); the Social Support from Family and Friends Scale (SSA); an index of satisfaction with different developmental contexts (home, school, neighbourhood); and as indicators of subjective well-being, three scales (Single item on Overall Life Satisfaction, Personal Well-Being Index School Children, Students’ Life Satisfaction Scale). Results indicated that aggression and victimization behaviours correlated negatively with the three well-being indicators used, while social support and satisfaction with different developmental contexts correlated positively. When considering type of involvement in bullying, victims, perpetrators and perpetrator–victims all scored lower on subjective well-being than those not involved in bullying. A model is also presented that explains 42 % of well-being. Understanding how bullying relates to well-being and how social support and favourable developmental contexts can act as protective factors are particularly important when designing public policies aimed at intervening in violence prevention and promoting well-being in childhood and adolescence.     

The Role of Couple Discrepancies in Cognitive and Behavioral Egalitarianism in Marital Quality

Although gender ideologies and perceptions of equity in the division of household tasks have been associated with marital quality, there is limited understanding of the relationship between discrepancies (in husbands’ and wives’ subjective ideals and accounts of the division of labor) and relationship quality. We examined cognitive egalitarianism (beliefs about gender roles), behavioral egalitarianism (perceptions of the division of household tasks and management), and marital quality among 220 heterosexual, newlywed couples (N?=?440) living in east and central regions of the United States. We used multi-level modeling to examine associations between cognitive egalitarianism, behavioral egalitarianism, and marital quality with a specific focus on discrepancies in the reports of husbands and wives. As hypothesized, both husbands and wives had lower marital quality when their cognitive egalitarianism was discrepant from their partner, and such a discrepancy had a greater influence on wives’ reports of marital quality, especially for wives with higher cognitive egalitarianism. Although we expected similar results for the associations between behavioral egalitarianism and marital quality, we found that the strength of the association between wives’ behavioral egalitarianism and marital quality decreased as the discrepancy from their husbands’ behavioral egalitarianism increased. The association between cognitive egalitarianism and marital quality also increased as behavioral egalitarianism increased for wives but not for husbands. The results of this study illustrate the central role of spousal discrepancy in perceptions and enactment of household labor.     

Perceiving subjectivity in bodily movement: The case of dancers

This paper is about one of the puzzles of bodily self-consciousness: can an experience be both and at the same time an experience of one′s physicality and of one′s subjectivity? We will answer this question positively by determining a form of experience where the body′s physicality is experienced in a non-reifying manner. We will consider a form of experience of oneself as bodily which is different from both “prenoetic embodiment” and “pre-reflective bodily consciousness” and rather corresponds to a form of reflective access to subjectivity at the bodily level. In particular, we argue that subjectivity is bodily expressed, thereby allowing the experience of the body′s subjectivity directly during perceptual experiences of the body. We use an interweaving of phenomenological explorations and ethnographical methods which allows validating this proposal by considering the experience of body experts (dancers).     

The On-Line Processing of Verb-Phrase Ellipsis in Aphasia

We investigate the on-line processing of verb-phrase ellipsis (VPE) constructions in two brain injured populations: Broca’s and Anomic aphasics. VPE constructions are built from two simple clauses; the first is the antecedent clause and the second is the ellipsis clause. The ellipsis clause is missing its verb and object (i.e., its verb phrase (VP)), which receives its reference from the fully specified VP in the antecedent clause. VPE constructions are unlike other sentence types that require displacement of an argument NP; these latter constructions (e.g., object-relatives, wh-questions) yield either on-time or delayed antecedent reactivation. Our results demonstrate that Anomics, like unimpaired individuals, evince reactivation of the direct object NP (within the VP) at the elided position. Broca’s patients, on the other hand, do not show reactivation of the antecedent. We consider several interpretations for our data, including explanations focusing on the larger ‘grain size’ of the reconstructed material in the ellipsis clause, the properties of the auxiliary that carries tense and agreement features, and the possibility that the cost-free syntactic copy procedure claimed to underlie VPE may be modulated by the functional deficit in Broca’s aphasia.     

Positive emotional context eliminates the framing effect in decision-making

Dual-process theories have suggested that emotion plays a key role in the framing effect in decision-making. However, little is known about the potential impact of a specific positive or negative emotional context on this bias. We investigated this question with adult participants using an emotional priming paradigm. First, participants were presented with positive or negative affective pictures (i.e., pleasant vs. unpleasant photographs). Afterward, participants had to perform a financial decision-making task that was unrelated to the pictures previously presented. The results revealed that the presentation framed in terms of gain or loss no longer affected subjects' decision-making following specific exposure to emotionally pleasant pictures. Interestingly, a positive emotional context did not globally influence risk-taking behavior but specifically decreased the risk propensity in the loss frame. This finding confirmed that a positive emotional context can reduce loss aversion, and it strongly reinforced the dual-process view that the framing effect stems from an affective heuristic belonging to intuitive System 1.

Emotional expressions of female and male infants in a social and a nonsocial context

While observational studies of the emotional expressions of women and men have revealed several consistent patterns of gender differences, data pertaining to the emotional expressions of male and female infants are largely inconsistent. Attempting to trace the course of early emotional development in female and male infants, we undertook to compare the emotional expressions of boys and girls at 2 1/2 and 5 months of age in a variety of situations. All infants who participated in the study were from French-speaking Caucasian families of low and middle class. At each age level, infants were observed in a social and nonsocial situation. The social situation began with a mother—infant interaction, followed by a period during which the mother remained silent and still-faced. In the nonsocial situation, a mobile was presented and then removed. Infants' facial expressions were coded using the AFFEX system. Direction of gaze was also coded. Overall, boys' and girls' reactions were quite similar. At both ages, male and female infants spent more time looking at the toy than at their mother and showed more expressions of interest toward the toy. They also smiled more while interacting with their mother and displayed more negative expressions when facing their still-faced mother. One gender difference was found: At 2 1/2 months, girls smiled more than boys while interacting with their mother. Several explanations are proposed to account for these findings.     

Phosphorylation state of CREB in the rat hippocampus: a molecular switch between spatial novelty and spatial familiarity?

The activation of cAMP response element-binding protein (CREB) after a learning experience is a common feature in the formation of several associative memories. We recently demonstrated that the increase in the hippocampal phosphorylated CREB (pCREB) levels 1 h after a short exploration of an open field (OF) was associated to detection of spatial novelty and was not related to the memory formation of habituation in this non-associative learning paradigm. Moreover, after a long training of three OF sessions, hippocampal pCREB levels were below to that observed in control rats. The present results show that such decrease does not correlate with memory retrieval or improvement in long-term memory of habituation. Instead, it is associated with the familiarity to the arena. Our experiments revealed that the relevant variable to induce CREB deactivation was the prolonged exploration of the arena (30 min). A 15 min OF exploration was ineffective. Furthermore, the last 5 min period of a prolonged exploration was crucial to change CREB phosphorylation state: when exploration took place in a novel arena the level of pCREB increased; in contrast, when it was performed in the familiar OF, pCREB levels decreased. Taken as a whole, our results suggest that CREB phosphorylation state in the hippocampus switches in response to exposure to a novel or to a familiar spatial environment.     

Hemispheric differences in the time-course of semantic priming processes: evidence from event-related potentials (ERPs)

To investigate hemispheric differences in the timing of word priming, the modulation of event-related potentials by semantic word relationships was examined in each cerebral hemisphere. Primes and targets, either categorically (silk-wool) or associatively (needle-sewing) related, were presented to the left or right visual field in a go/no-go lexical decision task. The results revealed significant reaction-time and physiological differences in both visual fields only for associatively related word pairs, but an electrophysiological difference also tended to reach significance for categorically related words when presented in the left visual field. ERP waveforms showed a different time-course of associative priming effects according to the field of presentation. In the right visual field/left hemisphere, both N400 and Late Positive Component (LPC/P600) were modulated by semantic relatedness, while only a late effect was present in the left visual field/ right hemisphere.
