Diffusion models of the flanker task: discrete versus gradual attentional selection

The present study tested diffusion models of processing in the flanker task, in which participants identify a target that is flanked by items that indicate the same (congruent) or opposite response (incongruent). Single- and dual-process flanker models were implemented in a diffusion-model framework and tested against data from experiments that manipulated response bias, speed/accuracy tradeoffs, attentional focus, and stimulus configuration. There was strong mimcry among the models, and each captured the main trends in the data for the standard conditions. However, when more complex conditions were used, a single-process spotlight model captured qualitative and quantitative patterns that the dual-process models could not. Since the single-process model provided the best balance of fit quality and parsimony, the results indicate that processing in the simple versions of the flanker task is better described by gradual rather than discrete narrowing of attention.     

Beyond rhyme or reason: ERPs reveal task-specific activation of orthography on spoken language

Metaphonological tasks, such as rhyme judgment, have been the primary tool for the investigation of the effects of orthographic knowledge on spoken language. However, it has been recently argued that the orthography effect in rhyme judgment does not reflect the automatic activation of orthographic codes but rather stems from sophisticated response strategies. Such a claim stands in sharp contrast with recent findings using event-related brain potentials (ERPs) in lexical and semantic tasks, which were taken to suggest that orthographic information occurs early enough to affect the core process of lexical access. Here, we show that the electrophysiological signature of the orthography effect in rhyme judgment is indeed different from the one obtained in online lexical or semantic tasks. That is, we did not find the orthography effect in the 300-350 ms time window which has previously been shown to process lexical information in the lexico-semantic tasks, but the effect appeared within the 175-250 ms and the 375-750 ms time-windows which we interpreted to reflect segmentation and decisional process, respectively. We conclude that the interactions between phonology and orthography are task-specific. Metaphonological tasks appear of limited use for studying the core processes and interactions that underlie lexical access.     

Critical refl ections on intersubjectivity in psychoanalysis1

The authors review the philosophical trend known as postmodernism and the way it has infl uenced a part of psychoanalytic thought, concluding with some comments on the qualities and shortcomings of the new developments. The authors consider the origins and the cultural and aesthetic‐philosophical meaning of postmodernism, identifying some key concepts such as deconstructionism, the disappearance of the ‘individual subject’ and individual identity, and the rejection of ‘in‐depth’ models of psychoanalysis. Then they examine various, wide‐ranging developments in psychoanalytic thought and treatment. They review the intersubjective fi eld in psychoanalysis, especially in the USA, and then explore whether the underlying lack of truth to be discovered, stressed by these ‘new view’ statements, or the fact that the ‘truth’ only exists in linguistic‐narrative constructions is consistent with basic analytic concepts such as the unconscious, phantasy, transference and countertransference, which recall the tri‐dimensional nature of inner psychic reality. The psychoanalytic process is a condition activated through a bond that is able to hold and contain the relationship of the analytic couple and the patient's unconscious world and not through hermeneutic or narrative constructions.     

The analyst's countertransference to the psychoanalytic process1

There is countertransference, not just to individual patients, but to the process of psychoanalysis itself. The analytic process is a contentious topic. Disagreements about its nature can arise from taking it as a unitary concept that should have a single defi nition whereas, in fact, there are several strands to its meaning. The need for the analyst's free associative listening, as a counterpart to the patient's free associations, implies resistance to the analytic process in the analyst as well as the patient. The author gives examples of the self‐analysis that this necessitates. The most important happenings in both the analyst's and the patient's internal worlds lie at the boundary between conscious and unconscious, and the nature of an analyst's interventions depends on how fully what happens at that boundary is articulated in the analyst's consciousness. The therapeutic quality of an analyst's engagement with a patient depends on the freeing and enlivening quality, for the analyst, of the analyst's engagement with his or her countertransference to the analytic process.     

内隐记忆研究的回顾与展望

近年来,在对内隐记忆的存在性和本质特点进行探讨的过程中,该领域涌现出愈加丰富的实验室研究方法和理论观点,同时也引发了研究者对内隐记忆内涵的深入思考。逐渐细分的内隐记忆研究领域促使人们超越内隐记忆原有的理论框架,去建构一个整合外显记忆与内隐记忆,容纳记忆的无意识和意识过程的完整理论体系。     

The Contributing Factors of Change in a Therapeutic Process

The clients’ and therapists’ perceptions about the degree to which each of four common factors in therapy—extra-therapeutic factors; model/techniques; therapeutic alliance; and hope/expectancy—contribute to change in the therapeutic process were investigated in this study. In addition, the perceptions about the percentage of change attributed to clients and therapists were also explored. Results revealed that the therapists and clients have different perceptions on what factors contribute the most to change and that clients and therapists believe that the client contributes the most to change in a therapeutic process.M.

汉语单音节词汇产生中的激活反馈

采取图画-词汇干扰实验范式,探索汉语词汇产生中词条选择和音韵编码两个阶段之间是否存在激活的反馈。实验一探索的是字形激活能否反馈至语义层产生语义激活,结果发现,与无关条件相比,目标图画(如“锯”)的字形中介(“镇”)的语义相关字(“村”)条件显著地延长了图画命名的时间。这表明在汉语词汇产生过程中,字形层的激活能反馈至语义层。实验二探索的是语音激活能否反馈至语义层产生语义激活,结果发现,与无关条件相比,目标图画(“梨”)的语音中介(“厘”)的语义相关字(“毫”)条件并未显著地影响图画命名的时间。这表明语音层的激活不能反馈至语义层,或者反馈回的激活太微弱不能影响图画命名过程。实验一和二的结果更倾向于支持词汇产生中词条选择和音韵编码两个阶段独立的观点。
