意向保持间隔对时间性前瞻记忆的影响

通过两个实验来探讨意向保持间隔对时间性前瞻记忆的影响。实验一仅通过嵌入前瞻目标的背景任务来操纵保持间隔,实验二通过在背景任务之前加入不同时长的填充任务来改变意向保持间隔。结果发现,(1)背景任务中的保持间隔越长,前瞻记忆成绩越差;(2)背景任务中的保持间隔和填充任务的时长对前瞻记忆的影响存在交互作用。成绩最好的为15min-2min组,最差的为15min-15min组。结果表明,背景任务和填充任务阶段对于个体保持前瞻意向可能有不同的功能。     

Awareness training reduces college students' speech disfluencies in public speaking

Recent research suggests that a modified habit reversal procedure, including awareness training alone or combined with competing response training, is effective in decreasing speech disfluencies for college students. However, these procedures are potentially lengthy, sometimes require additional booster sessions, and could result in covariation of untargeted speaker behavior. We extended prior investigations by evaluating awareness training as a sole intervention while also measuring collateral effects of treatment on untargeted filler words and rate of speech. We found awareness training was effective for all participants without the use of booster sessions, and covariation between targeted filler words and secondary dependent variables was idiosyncratic across participants.     

Filler + Infinitive and Pre- and Protomorphology Demarcation in a French Acquisition Corpus

This paper presents a case study on the acquisition of grammatical morphemes via fillers, i.e., underspecified place holders, with particular focus on early structures made up of a filler followed by an infinitive. The path leading from fillers to French semi-auxiliaries and subject clitics is analyzed within the framework of Natural Morphology and constructivism which assumes that grammatical modules are not innate but are constructed by children. The evolution of fillers in the corpus studied is described as a grammaticization process of form and meaning through successive linguistic dissociations. Emphasis is put on the functional polyvalence of fillers and on their relation to the main phases in the construction of grammar.     

Another Look at the Role of Empty Categories in Sentence Processing (and Grammar)

The gap/gapless processing debate in the psycholinguistics literature contrasts two processing models: one that assumes the trace-based Government and Binding (or Principles and Parameters) Grammar and the (augmented) Active Filler Strategy and one that assumes the traceless Dependency Categorial Grammar and the Principle of Dependency Formation. This paper reports on an experiment that found new evidence against the gapless/traceless model, considers why such evidence was not found in previous studies, and explores whether a parser that combines a (partially) traceless grammar and the augmented Active Filler Strategy can explain the current finding.
