Structural priming: a critical review

Repetition is a central phenomenon of behavior, and researchers have made extensive use of it to illuminate psychological functioning. In the language sciences, a ubiquitous form of such repetition is structural priming, a tendency to repeat or better process a current sentence because of its structural similarity to a previously experienced ("prime") sentence (J. K. Bock, 1986). The recent explosion of research in structural priming has made it the dominant means of investigating the processes involved in the production (and increasingly, comprehension) of complex expressions such as sentences. This review considers its implications for the representation of syntax and the mechanisms of production and comprehension and their relationship. It then addresses the potential functions of structural priming, before turning to its implications for first language acquisition, bilingualism, and aphasia. The authors close with theoretical and empirical recommendations for future investigations.     

Autonomous construction of ecologically and socially relevant semantics

This article presents a synthetic modeling approach to the problem of grounded construction of concepts. In many computational models of grounded language acquisition and evolution, meanings are created in the process of discrimination between a chosen object and other objects present on the scene of communication. We argue that categories constructed for the purpose of identification rather than discrimination are more suitable for the detached language use (talking about things not present here and now). We describe a semantics based on so-called identification criteria constructed by extracting cross-situational similarities among instances of a category, and present several computational models. In the model of individual category construction, the instances are grouped to categories by common motor programs (affordances), while in the model of social learning, focused on the influence of naming on category formation, entities are considered members of the same category, if they are labeled with the same word by an external teacher. By these two mechanisms, the learner can construct interactionally grounded representation of objects, properties, relations, changes, complex situations and events. We also report and analyze simulation results of an experiment focused on the dynamics of meanings in iterated intergenerational transmission.     

Variation in the serotonin transporter gene modulates selective attention to threat

The 5-HTTLPR is an insertion/deletion polymorphism in the promoter region of the serotonin transporter gene. Prior research has revealed associations between the short-allele variant of this polymorphism, enhanced self-reported negative emotionality, and hypersensitivity of fear relevant neural circuits. In a sample of 50 healthy women we examined the role of 5-HTTLPR for cognitive-affective processing of phylogenetical fear-relevant stimuli (spiders) in a dot probe task. In contrast to homozygote long-allele carriers (ll), participants carrying at least 1 short allele (ss and sl) selectively shifted attention toward pictures of spiders, when these were presented for a duration of 2,000 ms. These results argue for an involvement of 5-HTTLPR in cognitive processing of threatening stimuli and thus, underpin its general role for individual differences in negative affect.     

Confounds in pictorial sets: The role of complexity and familiarity in basic-level picture processing

Complexity is conventionally defined as the level of detail or intricacy contained within a picture. The study of complexity has received relatively little attention-in part, because of the absence of an acceptable metric. Traditionally, normative ratings of complexity have been based on human judgments. However, this study demonstrates that published norms for visual complexity are biased. Familiarity and learning influence the subjective complexity scores for nonsense shapes, with a significant training x familiarity interaction [F(1,52) = 17.53, p < .05]. Several image-processing techniques were explored as alternative measures of picture and image complexity. A perimeter detection measure correlates strongly with human judgments of the complexity of line drawings of real-world objects and nonsense shapes and captures some of the processes important in judgments of subjective complexity, while removing the bias due to familiarity effects.     

Psychopathologie und Behandlung der Borderline-Persönlichkeitsstörung

Zusammenfassung Das Wissen über Psychopathologie, Ätiopathogenese und Behandlungsmöglichkeiten der Borderline-Persönlichkeitsstörung (BPS) hat sich in den letzten Jahren deutlich verbessert. Heute sehen die meisten Wissenschaftler eine generalisierte Störung der Affektregulation im Zentrum der BPS, deren Ursachen in Wechselwirkungen zwischen genetischen Faktoren, traumatischen biographischen Erfahrungen und dysfunktionalen Verhaltensmustern liegen. Störungsspezifische Therapieverfahren, insbesondere die Dialektisch Behaviorale Therapie (DBT) nach Linehan, flankiert von psychopharmakologischer Behandlung, zeigen gute Behandlungsergebnisse sowohl im stationären als auch im ambulanten Bereich. In jüngster Zeit wurden viel versprechende Konzepte zur Behandlung schwerer komorbider Störungen [Alkohol und Drogenabhängigkeit, Posttraumatische Belastungsstörung (PTBS)] entwickelt.     

Perceptions of Police Use of Deadly Force

Recent police shootings of unarmed suspects have brought to bear harsh criticism of law enforcement use of deadly force. Two studies sought to investigate perceptions of police misuse of deadly force. Study 1 showed that as number of officers decreased and number of shots increased, perceptions of misuse of force were augmented. Number of shots per officer significantly predicted perceptions of misuse of force. Study 2 investigated the effects of social dominance orientation, blind patriotism, and right-wing authoritarianism. Results showed a significant interaction between number of officers, number of shots fired, and social dominance orientation. This personality variable was an especially strong predictor of misuse of force in situations involving the largest number of shots fired per officer.     

Why opening a door is as easy as eating an apple: A reply to Thompson-Schill and Botvinick (2006)

Martin and Cheng (2006) present evidence suggesting that difficulty in verb generation is related to the strength of associative links between nouns and verbs and not to competition from alternative verb responses. Specifically, they show that latencies for verb generation are related to the associative strength of the most frequently produced verb and not to the ratio of the strength of the first to the second most frequently produced verb. Thompson-Schill and Botvinick (2006) have provided modeling results indicating how the findings of Martin and Cheng might be accommodated in a competitive model. Here we discuss how two noncompetitive models account for the findings and why such models should be preferred.     

Epicureanism About Death and Immortality

In this paper I discuss some of Martha Nussbaum’s defenses of Epicurean views about death and immortality. Here I seek to defend the commonsense view that death can be a bad thing for an individual against the Epicurean; I also defend the claim that immortality might conceivably be a good thing. In the development of my analysis, I make certain connections between the literatures on free will and death. The intersection of these two literatures can be illuminated by reference to my notion of a Dialectical Stalemate.     

Relating different perspectives on how outcomes of behavior influence behavior

Many researchers have tackled the question of how behavior is influenced by its outcomes. Some have adopted a nonmechanistic (functional) perspective that attempts to describe the influence of outcomes on behavior. Others have adopted a mechanistic (cognitive) perspective that attempts to explain the influence of outcomes on behavior. Orthogonal to this distinction, some have focused on the influence of outcomes that a behavior had in the past, whereas others also consider the influence of outcomes that a behavior might have in the future. In this article, we relate these different perspectives with the goal of reducing misunderstandings and fostering collaborations between researchers who adopt different perspectives on the common question of how behavior is influenced by its outcomes.
