情绪性注意与外源性注意的竞争作用

注意选择机制并不是一个单一的系统,而是多个具有不同选择标准和功能的复合系统.情绪性注意与外源性注意这两种注意选择过程是否可以同时作用,它们之间是否会相互干扰,抑或某一种注意过程是否占优势？本研究以30名在校大学生为被试,采用经典点探测任务的变式,对50ms和500ms两种SOA条件下,以愉快面孔和恐惧面孔作为情绪性注意的提示线索,对情绪性注意与外源性注意的相互关系进行探讨.发现两种注意是相互竞争的,都对注意产生效应.在短SOA条件下,恐惧面孔作为情绪性提示的线索时,情绪性注意和外源性注意会发生相互作用.而愉快面孔作为情绪性提示线索时,外源性注意更占主导作用.说明恐惧面孔比愉快面孔更能引发情绪性注意;在SOA为500ms时,情绪性注意和外源性注意均不再产生效应.再次说明,这两种注意是反射性、迅速的、自下而上的.     

Distorted subjective reports of stimulus onsets under dual-task conditions: Delayed conscious perception or estimation bias?

We investigated whether selecting a response for one task delays the conscious perception of another stimulus (delayed conscious perception hypothesis). In two experiments, participants watched a revolving clock hand while performing two tasks in close succession (i.e. a dual-task). Two stimuli were presented with varying stimulus onset asynchrony (SOA). After each trial, participants separately estimated the onsets of the two stimuli on the clock face. Across two experiments and four conditions, we manipulated response requirements and assessed their impact on perceived stimulus onsets. Results showed that (a) providing speeded responses to the stimuli did lead to greater SOA-dependent misperceptions of both stimulus onsets as compared to a solely perceptual condition, and (b) that response grouping reduced these misperceptions. Overall, the results provide equivocal evidence for the delayed conscious perception hypothesis. They rather suggest that participants’ estimates of the two stimulus onsets are biased by the interval between their responses.     

Bartlett revisited: Direct comparison of repeated reproduction and serial reproduction techniques

Bartlett developed the procedures of repeated reproduction (the same person repeatedly recalling information) and serial reproduction (people transmitting information from one person to another). Our experiment directly compared recall accuracy across these two techniques, which has not previously been reported, using DRM word lists. Recall of the initial study list words remained constant across repeated reproductions but declined markedly across serial reproductions. In contrast, recall of associated words that were not originally studied (i.e. critical words) was steady across both conditions. Because more of the original list words were forgotten across each link of the serial reproduction chain, the proportion of critical items recalled (relative to list words) increased significantly as the list passed between people. Using output bound scoring, serial reproduction resulted in lower accuracy than repeated reproduction by the final recall trial. Our results are broadly consistent with Bartlett's (1932) informal observations: Serial reproduction produces greater forgetting of the original material than does repeated reproduction and also leads to greater distortion relative to the proportion of correct material recalled.     

抑制范式下的情绪注意偏向

与中性信息相比,情绪信息会引起更快更多的注意并具有一种认知加工上的优先权.在注意实验中,与不带情绪色彩的刺激相比,具有情绪意义的刺激更能吸引注意或占用注意资源且引起注意偏向.个体对情绪信息的适度偏向具有重要的社会生活意义.本文介绍了情绪注意偏向的注意成分理论、图式理论、注意资源理论和平行分布处理(PDP)模型,并分别对抑制范式下以不同情绪材料展开的正常被试和特殊被试的情绪注意偏向研究进行了总结概括,同时指出了未来在抑制范式下利用ERPs、fMRI新技术研究不同被试群体情绪与注意关系的可能性.     

The Violation of Expectancies

ABSTRACT

The term “violation of expectancies” is derived from empirical studies of early development by Beebe and Lachmann. It referred, in their lexicon, to the interaction of mother and infant, organized by disruptions and efforts to resolve these breaches. This article expands the term's meaning to include a broad range of disruptive experiences, occurring not only in infancy but throughout the life cycle. The author's premise is that a developmental continuity exists between infant states and adult psychopathological states. This requires that we look in infancy for beginnings of states that we recognize as existing later on. The author provides a detailed review of infancy research, so as to give credence and support to the significance of the concept of violation of expectancy, and how these violations play a dominant role in the thematic and nuanced reverberations of our lives and in the intersubjective context of our experience. The concept of trauma derives from a one-person psychology, and is connected to unconscious fantasy, conflict and compromise formation, whereas “violation of expectancy” is a relational concept, based on mother-child interactions and originating within an intersubjective context. The author provides three case examples of violation of expectancy and their reverberations: The first involves early and repeated disruption in infancy, the second occurs in a relatively intact child, and the third derives from an autobiographical character.     

Semantic relatedness among objects promotes the activation of multiple phonological codes during object naming

In a picture–word interference experiment the authors demonstrate that a semantic–categorical relation between a to-be-named target picture and a context picture promotes the phonological activation of the to-be-ignored context picture. No such phonological activation is observed if the objects are semantically unrelated. This finding gives further insight into the mechanisms that modulate the activation flow in the conceptual-lexical system during speech planning. In contrast to recent picture–picture interference studies, the results provide direct evidence that the phonological activation of a context object is dependent on its semantic processing.     

Development of parafoveal processing within and across words in reading: Evidence from the boundary paradigm

In this study we used the boundary paradigm to examine whether readers extract more parafoveal information within than across words. More specifically, we examined whether readers extract more parafoveal information from a compound word's second constituent than from the same word when it is the noun in an adjective–noun phrase (kummitustarina “ghost story” vs. lennokas tarina “vivid story”). We also examined whether the processing of compound word constituents is serial or parallel and how parafoveal word processing develops over the elementary school years. Participants were Finnish adults and 8-year-old second-, 10-year-old fourth-, and 12-year-old sixth-graders. The results showed that for all age groups more parafoveal information is extracted from the second constituent within compounds than from the noun in adjective–noun phrases. Moreover, for all age groups we found evidence for parallel processing of constituents within compounds, but only when the compounds were of high frequency. In sum, the present study shows that attentional allocation extends further to the right and is more simultaneous when words are linguistically and spatially unified, providing evidence that attention in text processing is flexible in nature.     

Task-switching cost and repetition priming: Two overlooked confounds in the fixed-set procedure of the Sternberg paradigm and how they affect memory set-size effects

Subjects performed Sternberg-type memory recognition tasks (Sternberg paradigm) in four experiments. Category-instance names were used as learning and testing materials. Sternberg's original experiments demonstrated a linear relation between reaction time (RT) and memory-set size (MSS). A few later studies found no relation, and other studies found a nonlinear relation (logarithmic) between the two variables. These deviations were used as evidence undermining Sternberg's serial scan theory. This study identified two confounding variables in the fixed-set procedure of the paradigm (where multiple probes are presented at test for a learned memory set) that could generate a MSS RT function that was either flat or logarithmic rather than linearly increasing. These two confounding variables were task-switching cost and repetition priming. The former factor worked against smaller memory sets and in favour of larger sets whereas the latter factor worked in the opposite way. Results demonstrated that a null or a logarithmic RT-to-MSS relation could be the artefact of the combined effects of these two variables. The Sternberg paradigm has been used widely in memory research, and a thorough understanding of the subtle methodological pitfalls is crucial. It is suggested that a varied-set procedure (where only one probe is presented at test for a learned memory set) is a more contamination-free procedure for measuring the MSS effects, and that if a fixed-set procedure is used, it is worthwhile examining the RT function of the very first trials across the MSSs, which are presumably relatively free of contamination by the subsequent trials.     

Why Utilize Complexity Principles in Social Inquiry?

Complexity is introduced as a fitting paradigmatic orientation to social inquiry. A complexity approach is compared and contrasted with other holistic social inquiry orientations (systems thinking, cybernetics, and ecological thinking) and constructivist styles of thinking that have informed and guided the evolution of qualitative social inquiry.     

The Case for integrated intelligence

In this article I develop a case for a theory of intelligence incorporating transpersonal dimensions, namely integrated intelligence. Some recent expanded theories of intelligence move into concepts like creativity, wisdom, and emotional intelligence. Yet they remain embedded within mainstream intelligence theory and its reductionist and materialist presuppositions. Although various theorists in consciousness theory have developed transpersonal models that are beginning to be discussed in some mainstream circles, mainstream intelligence theory is yet to address the broader implications of this. Recent changes in the global economy and the needs of populations have created a need for an expanded theory of intelligence, and more intuitive thinking.
