Asymptotic learning of alphanumeric coding in autobiographical memory

Studies of autobiographical memory have shown that observed levels of incidental learning are often relatively low. Do low levels of retention result simply from a low learning rate, or is learning also asymptotic? To address this question, it is necessary to trace performance over a large number of learning opportunities, and this was carried out in the context of the recent development of widespread texting behaviour. It was found that memory for the alphanumeric layout of a phone improved as a function of sending approximately the first 500 texts, but then the improvement stopped. The incidence of memory error was incompatible with a simple power-law relation but was modelled closely by an asymptotic relation. It is suggested that this pattern reflects a movement towards automaticity in the primary task which progressively closes down the possibility that incidental learning can occur.

Learning representations of wordforms with recurrent networks: comment on sibley, kello, plaut, & elman (2008)

Sibley et al. (2008) report a recurrent neural network model designed to learn wordform representations suitable for written and spoken word identification. The authors claim that their sequence encoder network overcomes a key limitation associated with models that code letters by position (e.g., CAT might be coded as C‐in‐position‐1, A‐in‐position‐2, T‐in‐position‐3). The problem with coding letters by position (slot‐coding) is that it is difficult to generalize knowledge across positions; for example, the overlap between CAT and TOMCAT is lost. Although we agree this is a critical problem with many slot‐coding schemes, we question whether the sequence encoder model addresses this limitation, and we highlight another deficiency of the model. We conclude that alternative theories are more promising.

The cognitive penetrability of perception: A blocked debate and a tentative solution

Despite the extensive body of psychological findings suggesting that cognition influences perception, the debate between defenders and detractors of the cognitive penetrability of perception persists. While detractors demand more strictness in psychological experiments, proponents consider that empirical studies show that cognitive penetrability occurs. These considerations have led some theorists to propose that the debate has reached a dead end. The issue about where perception ends and cognition begins is, I argue, one of the reasons why the debate is cornered. Another reason is the inability of psychological studies to present uncontroversial interpretations of the results obtained. To dive into other kinds of empirical sources is, therefore, required to clarify the debate. In this paper, I explain where the debate is blocked, and suggest that neuroscientific evidence together with the predictive coding account, might decant the discussion on the side of the penetrability thesis.     

Development of predictive responses in theory of mind brain regions

When we watch movies, we consider the characters’ mental states in order to understand and predict the narrative. Recent work in functional magnetic resonance imaging (fMRI) uses movie‐viewing paradigms to measure functional responses in brain regions recruited for such mental state reasoning (the theory of mind [“ToM”] network). Here, two groups of young children (n = 30 3–4 years old, n = 26 6–7 years old) viewed a short animated movie twice while undergoing fMRI. As children get older, ToM brain regions were recruited earlier in time during the second presentation of the movie. This “narrative anticipation” effect is specific: there was no such effect in a control network of brain regions that responds just as robustly to the movie (the “Pain Matrix”). These results complement prior studies in adults that suggest that ToM brain regions play a role not just in inferring, but in actively predicting, other people's thoughts and feelings, and provide novel evidence that as children get older, their ToM brain regions increasingly make such predictions.     

"Articulation"与后马克思主义的偶然性逻辑--从拉克劳和墨菲的"articulation"谈起

该文认为,“articulation”是拉克劳、墨菲的后马克思主义的一个核心概念,它的基本意思是“链结”。该文从词源上考察了“articulation”一词的意义及其历史演变,并对其基本含义和特征做了深入的分析。该文认为,链接是理解后马克思主义的偶然性逻辑的核心概念。链接是发生在主体身份之间的,话语性的,偶然性的建构实践活动。但拉克劳、墨菲的链接虽然力图避免近代哲学的本质主义和还原主义,但却仍然避免不了其精致的“唯心”倾向和向上的还原论的嫌疑。我们对此要有清晰的认识。     

内隐序列学习的表征机制及年龄效应研究

该研究从年龄效应这一独特视角探讨了内隐序列学习的表征机制。结果表明:(1)内隐序列学习存在具体联结和抽象层级编码双重表征机制,且在该研究中以抽象编码为主;(2)老、青、幼三组被试的内隐序列学习无显著差异,间接支持了具体联结机制不起主要作用的结论。该研究的推论是:(1)内隐序列学习的表征是一个遵循“最优级编码”的动态过程;(2)该过程不涉及注意机制和短时记忆。     

Optimal or Typical Performance? The Impact of Instructional Set on the Behavioral Assessment of Parent-Child Interactions

The behavioral assessment of parent-child interactions is an important component of treatment planning and evaluation in many evidence-based parent training programs. However, numerous factors unrelated to the parent-child interaction may add error to the assessment. This study investigated the impact of task instructions on parents’ behaviors during the analogue parent-child interaction observation, the Dyadic Parent-Child Interaction Coding System (DPICS). Forty-eight mother-child dyads were randomly assigned to one of two conditions that differed on level of specificity of instructions. Significant differences were observed between groups, with parents who received specific instructions using more praises during the DPICS tasks. Specific instructions may shift parents’ behaviors toward optimal, rather than typical, interaction patterns and should be considered in the context of the assessment goals.
