Neural circuitry of the bilingual mental lexicon: Effect of age of second language acquisition

Numerous studies have proposed that changes of the human language faculty caused by neural maturation can explain the substantial differences in ultimate attainment of grammatical competences between first language (L1) acquirers and second language (L2) learners. However, little evidence on the effect of neural maturation on the attainment of lexical knowledge in L2 is available. The present functional magnetic resonance study addresses this question via a cross-linguistic neural adaptation paradigm. Age of acquisition (AoA) of L2 was systematically manipulated. Concrete nouns were repeated across language (e.g., French–German, valise^suitcase–Koffer^suitcase). Whereas early bilinguals (AoA of L2 < 3 years) showed larger repetition enhancement (RE) effects in the left superior temporal gyrus, the bilateral superior frontal gyrus and the right posterior insula, late bilinguals (AoA of L2 > 10 years) showed larger RE effects in the middle portion of the left insula and in the right middle frontal gyrus (MFG). We suggest that, as for grammatical knowledge, the attainment of lexical knowledge in L2 is affected by neural maturation. The present findings lend support to neurocognitive models of bilingual word recognition postulating that, for both early and late bilinguals, the two languages are interconnected at the conceptual level.     

Continuous priming effects on discrete response choices

When primed by backward-masked, target-like stimuli, discrete responses (e.g. button presses) to simple visual targets can be slower when prime and target match (compatible) than when they do not (incompatible). The current study investigated the nature of the stimulus–response mapping underlying this negative compatibility effect (NCE). Discrete left–right responses to arrow targets were primed with arrows oriented in one of 16 directions. Responses were either a standard button press or a 10 cm movement on a graphics tablet. Both tasks showed an identical NCE; importantly, reaction times in both tasks decreased smoothly as the angular distance between prime and target increased (i.e. as compatibility decreased), with the largest NCE evident between the extreme cases (prime-target distances of 0° and 180°). Primes exerted an effect on the required response in proportion to the amount of overlap (reflecting population vector coding). The mapping between the priming stimulus and response is continuous, not categorical.     

Marital commitment,money and marriage preparation: What changes after the wedding?

This paper explores conceptions of commitment and styles of money management in heterosexual couples at two points in time: Just before the wedding (T1) and about a year later (T2). It also examines the potential effects of using FOCCUS as a form of marriage preparation (MP). Forty‐two couples were recruited at T1 and randomly allocated to either A MP group and a group that would not be offered any marriage preparation ‐ the Non‐Marriage Preparation group (NMP). Individual, in‐depth, semi‐structured interviews were carried out at T1 and T2, recorded and fully transcribed. A thematic analysis (TA) yielded three themes or levels of commitment which were used to categorize couples at T1 and T2. Their money management styles were defined based on Pahl's ( 1989 ) typology. The results showed that conceptions of commitment had developed slightly overall by T2, and had been enhanced in the MP group. At T2, a more elaborated conception of commitment was associated with a greater tendency to treat money as a collective resource. Copyright © 2010 John Wiley & Sons, Ltd.     

Self-specific priming effect

Priority of the “self” is thought to be evolutionarily advantageous. However, evidence for this priority has been sparse. In this study, subjects performed a gender categorization task on self- and non-self target faces preceded by either congruent (same gender as target) or incongruent (different gender) periliminal (33 ms) or subliminal (17 ms) primes. We found that subliminal primes induced a priming effect only on self target faces. This discovery of a self-specific priming effect suggests that functional specificity for faces may include timing as well as spatial adaptations.     

Might an overweight waitress make you eat more? How the body type of others is sufficient to alter our food consumption

This paper investigates how people's food choices can be shaped by the body type of others around them. Using a professionally constructed obesity prosthesis, we show that the body type of a (confederate) server in a taste test study was sufficient to alter both the quantity (Experiment 1) and specific choices (Experiment 2) participants made but that chronic dieters and non-dieters exhibited opposite effects. While non-dieters ate more snacks when the server was thin, dieters ate more when the server was heavy. Dieters were also more persuaded by a heavy (vs. a thin) server, choosing both a healthy and unhealthy snack more often when she recommended it to them. We suggest these results may be attributable to identification with the server.     

行为决策中作为价值的时间:基于与金钱的比较

传统经济学家认为,时间就是金钱,而近年来的一些研究却发现了与之不同的结论。后续的研究者主要从损失和受益时的风险偏好和决策依据、沉没成本效应、心理账户和禀赋效应这四个方面对时间和金钱进行比较,但是这方面的研究还处于起步阶段,还有许多问题需要在以后的研究中深入探讨。未来的研究应对时间是否存在损失规避和敏感性递减、时间的沉没成本效应和时间的禀赋效应的形成机制等问题进行探讨。     

掩蔽启动范式中的负相容效应——知觉阶段的交互还是反应阶段的抑制

掩蔽启动范式中, 当掩蔽刺激与目标刺激的时间间隔达到100~200ms时, 出现负相容效应。负相容效应是指相容条件的反应时大于不相容条件, 错误率高于不相容条件。目前主要有三种理论来解释负相容效应的发生机制, 分别是自我抑制理论、目标更新理论和掩蔽抑制理论。三种理论探讨了负相容效应发生的机制, 即负相容效应发生在知觉阶段还是反应阶段, 涉及自我引发抑制还是刺激引发抑制。有关负相容效应发生的机制还需进一步的探讨。     

'Projective transidentifi cation': An extension of the concept of projective identifi cation

Questions about the concept of projective identifi cation still persist. The author presents the following hypotheses: Klein's traditional view and Bion's extension and revision of it can be thought of as occupying a continuum in reverse. He postulates that Bion's concept of communicative intersubjective projective identifi cation (which the author renames 'projective transidentifi cation') is primary and inclusive of Klein's earlier unconscious, omnipotent, intrapsychic mode but includes Bion's 'realistic' communicative mode as well. The author hypothesizes, consequently, that intersubjective projective identifi cation constitutes both the operation of an unconscious phantasy of omnipotent intrapsychic projective identifi cation solely within the internal world of the projecting subject-in addition to two other processes: conscious and/or preconscious modes of sensorimotor induction, which would include signaling and/or evocation or prompting gestures or techniques (mental, physical, verbal, posturing or priming) on the part of the projecting subject; followed by spontaneous empathic simulation in the receptive object of the subject's experience in which the receptive object is already inherently 'hard-wired' to be empathic with the prompting subject.     

The vengeance puzzle—retributive justice or hostile aggression?

Vengeance is understood as a blend of instrumental and hostile aggression. Taking the Berkowitz neoassociationistic aggression model as a basis, 84 students received a priming manipulation (anger, fear, or control condition). Afterwards, they judged one of four vengeance scenarios that differed in victim‐perpetrator relationship (coworker vs. stranger) and in the attributed motive of the perpetrator. Priming had an influence on judgments of injustice and on anticipated fury, but no effect whatsoever on aggression (measured as the decrease in well‐being wished for the perpetrator). The type of relationship had an effect only on anticipated disappointment. The main effects of motive were found on aggression and on the anticipated feeling of the perpetrator after the act. Aggression could be predicted from the motive of the perpetrator and well‐being of the victim after the transgression. Neither anticipated fury, importance of deterrence, nor judgment of injustice predicted aggression. Aggr. Behav. 00:1–12, 2005. © 2005 Wiley‐Liss, Inc.     

Don’t stereotype, think different! Overcoming automatic stereotype activation by mindset priming

Automatic stereotype activation can be overcome intentionally and after an extensive training. However, intentions have to be tailored to a certain social category. It is hypothesized that activating the mindset “think different” by priming creativity prevents stereotypes and associations in general from becoming automatically activated. In two experiments a creative, a thoughtful or no mindset was activated. Afterwards, the activation of associations was measured using a lexical decision task with semantic priming. As predicted, the automatic activation of stereotypes (Study 1) and other associations (Study 2) was found in the control conditions but not in a creative mindset. These results suggest that people possess a mindset that allows for overcoming automatic stereotype activation without being tailored to a specific category.
