Information structure expectations in sentence comprehension

In English, new information typically appears late in the sentence, as does primary accent. Because of this tendency, perceivers might expect the final constituent or constituents of a sentence to contain informational focus. This expectation should in turn affect how they comprehend focus-sensitive constructions such as ellipsis sentences. Results from four experiments on sluicing sentences (e.g., The mobster implicated the thug, but we can't find out who else) suggest that perceivers do prefer to place focus late in the sentence, though that preference can be mitigated by prosodic information (pitch accents, Experiment 2) or syntactic information (clefted sentences, Experiment 3) indicating that focus is located elsewhere. Furthermore, it is not necessarily the direct object, but the informationally focused constituent that is the preferred antecedent (Experiment 4). Expectations regarding the information structure of a sentence, which are only partly cancellable by means of overt focus markers, may explain persistent biases in ellipsis resolution.     

Inferior Frontal Regions Underlie the Perception of Phonetic Category Invariance

ABSTRACT— The problem of mapping differing sensory stimuli onto a common category is fundamental to human cognition. Listeners perceive stable phonetic categories despite many sources of acoustic variability. What are the neural mechanisms that underlie this perceptual stability? In this functional magnetic resonance imaging study, a short-interval habituation paradigm was used to investigate neural sensitivity to acoustic changes within and between phonetic categories. A region in the left inferior frontal sulcus showed a pattern of activation consistent with phonetic invariance: insensitivity to acoustic changes within a phonetic category and sensitivity to changes between phonetic categories. Left superior temporal regions, in contrast, showed graded sensitivity to both within- and between-category changes. These results suggest that perceptual insensitivity to changes within a phonetic category may arise from decision-related mechanisms in the left prefrontal cortex and add to a growing body of literature suggesting that the inferior prefrontal cortex plays a domain-general role in computing category representations.     

The influence of category coherence on inference about cross-classified entities

A critical function of categories is their use in property inference (Heit, 2000). However, one challenge to using categories in inference is that most entities in the world belong to multiple categories (e.g., Fido could be a dog, a pet, a mammal, or a security system). Building on Patalano, Chin-Parker, and Ross (2006), we tested the hypothesis that category coherence (the extent to which category features go together in light of prior knowledge) influences the selection of categories for use in property inference about cross-classified entities. In two experiments, we directly contrasted coherent and incoherent categories, both of which included cross-classified entities as members, and we found that the coherent categories were used more readily as the source of both property transfer and property extension. We conclude that category coherence, which has been found to be a potent influence on strength of inference for singly classified entities (Rehder & Hastie, 2004), is also central to category use in reasoning about novel cross-classified ones.     

Synaesthesia: learned or lost?

The question why synaesthesia, an atypical binding within or between modalities, occurs is both enduring and important. Two explanations have been provided: (1) a congenital explanation: we are all born as synaesthetes but most of us subsequently lose the experience due to brain development; (2) a learning explanation: synaesthesia is related to some learning process during childhood. Three recent studies provide conflicting support for these explanations. Two studies supported the idea that synaesthesia is learned by showing that the frequency of everyday language implicitly modulates the synaesthetic experience. Another study argued that synaesthesia reflects basic, innate magnitude representations. In this paper we reassess these points of view, and show that it is possible for both to be valid. These findings are integrated into an interactive specialization account of development in order to explain the neuronal mechanism underlying synaesthesia.     

Is there “smoke without fire”? Applying the theory of values to the study of motivational aspects of ethnic stereotypes: The case of Jewish stereotypes in Russia

Few studies have examined to what extent commonly held stereotypes reflect real intergroup differences in motivational goals. Taking a values perspective (Schwartz et al., 2012), the study examines value preferences among Jews and Russians in Russia, to assess the extent to which commonly held stereotypes reflect values of group members. Results showed that Jews reported substantially higher levels of universalism-tolerance, benevolence (both caring and dependability), and tradition values, and lower levels of power (both dominance and resources), and universalism-nature values, than Russians. Results indicated that the widespread Jewish stereotypes of power, achievement, and rootlessness/cosmopolitanism are ungrounded, while the stereotypes of liberalism and particularism are upheld by the reported differences in the value preferences between Jews and the majority population in Russia. The present study underscores the importance of value comparisons between ethnic minority and majority groups for understanding their motivational goals and thus fighting prejudices and discrimination.     

INCREASING AUTISTIC CHILDREN'S SPONTANEOUS VERBALIZATIONS OF AFFECTION: AN ASSESSMENT OF TIME DELAY AND PEER MODELING PROCEDURES

We assessed the efficacy of time delay and peer modeling procedures in increasing autistic children's spontaneous verbalizations of affection. Four autistic children were taught to spontaneously say “I like (love) you” in response to a hug from a familiar person and their mother. Generalization from a free play training setting to free play outdoors and at home was assessed. Ancillary social and affection behaviors were also observed. Results indicated that the time delay was a quick and effective procedure for all the children. Peer modeling was unsuccessful in teaching the target behavior.     

PERCEPTIONS OF BEHAVIORAL CONSISTENCY:

Abstract— Actors view behavior relevant for personality traits as more variable than observers do. This study was designed in replicate this actor-observer effect (AOE) in a common-target paradigm, test whether actors, observers, or both are intuitively aware of the AOE, and examine the effects of social projection on people's awareness of the AOE. Within each actor-observer pair, subjects described the actor on a series of trait adjectives and rated the consistency of relevant behavior. They then predicted the other person's ratings. The AOE emerged, and actors, but not observers, were aware of the effect On average, actors correctly predicted that observers rated actors' behavior as more consistent than actors themselves did Correlational analyses showed that actors and observers were equally prone to project their own ratings lo their matched partners
