Partial awareness distinguishes between measuring conscious perception and conscious content: Reply to Dienes and Seth

In their comment on Sandberg, Timmermans, Overgaard, and Cleeremans (2010), Dienes and Seth argue that increased sensitivity of the Perceptual Awareness Scale (PAS) is a consequence of the scale being less exclusive rather than more exhaustive. According to Dienes and Seth, this is because PAS may measure some conscious content, though not necessarily relevant conscious content, “If one saw a square but was only aware of seeing a flash of something, then one has not consciously seen a square.” In this reply, we claim that there is a difference between conscious visual experience, which may be partial, and the resulting conscious content, which is conceptual. Whereas PAS measures the first, confidence judgments and post-decision wagering measure the second.     

Action blindness in response to gradual changes

The goal of this study is to characterize observers’ abilities to detect gradual changes and to explore putative dissociations between conscious experience of change and behavioral adaptation to a changing stimulus. We developed a new experimental paradigm in which, on each trial, participants were shown a dot pattern on the screen. Next, the pattern disappeared and participants had to reproduce it. In some conditions, the target pattern was incrementally rotated over successive trials and participants were either informed or not of this change. We analyzed both awareness of the changes and the dynamics of behavioral adaptation, in a way that makes it possible to assess both variability and accuracy as they change over time. Results indicate a dissociation between change awareness and behavioral adaptation to the changes, and support the notion that unconscious representations of visual stimuli are more precise and detailed than previously suggested. We discuss the implications of these results for theories of change detection.     

Age-related differences in irrelevant-speech effects

Three experiments examined age-related differences in irrelevant-speech effects. Younger and older adults were required to recall short prose texts or lists of semantically related words presented visually together with distractor speech. In all experiments, older adults made more semantically related intrusion errors from the irrelevant speech than younger adults. Results of a source memory test suggested that these age-related differences in interference are most likely due to both inhibitory deficits and source-monitoring problems. The results lend partial support to the inhibition deficit theory of cognitive aging.     

承认与正义——多元正义理论纲要

在本文中,霍耐特概述了多元正义的理论.在论述的过程中,他没有从如何消除不平等的角度论述,而是从回避羞辱或蔑视的角度来讨论.他深信承认理论的正义构想所显示的社会不公的体验总是与公认的合理的承认没有得到认可有关.在文章中,霍耐特对南希·弗雷泽的研究方法持保留意见,即承认和再分配被分离成为两个概念总体,实现参与式平等的目标.相反,他觉得应该有一个关于认同形成的更细致的概念,这样,参与公共领域的活动意味着能够毫无羞愧地去参与,能够以一种自愿的形式来展示他或她个性的潜能,从而才能形成个体认同.从这个角度,霍耐特指出如果想获得个体认同,则人们必须获得的三种承认领域是:爱,法律承认和社会尊重.     

G*Power 3: A flexible statistical power analysis program for the social,behavioral, and biomedical sciences

G*Power (Erdfelder, Faul, & Buchner, 1996) was designed as a general stand-alone power analysis program for statistical tests commonly used in social and behavioral research. G*Power 3 is a major extension of, and improvement over, the previous versions. It runs on widely used computer platforms (i.e., Windows XP, Windows Vista, and Mac OS X 10.4) and covers many different statistical tests of thet, F, and χ₂ test families. In addition, it includes power analyses forz tests and some exact tests. G*Power 3 provides improved effect size calculators and graphic options, supports both distribution-based and design-based input modes, and offers all types of power analyses in which users might be interested. Like its predecessors, G*Power 3 is free.     

Equivalent irrelevant-sound effects for old and young adults

Three experiments are reported in which a total of 182 old and 193 young adults recalled sequences of digits presented visually in silence or accompanied by office noise. In each experiment, an effect of irrelevant sound was found-that is, a reduction of serial recall due to auditory distraction. Old adults exhibited poorer serial recall than did young adults, but the irrelevant-sound effect was equivalent in both age groups. This was true even though the sound level of the irrelevant sound was adjusted to each individual's hearing capability, and the effect remained whether or not the difficulty of the serial recall task was equated across age groups. These results are problematic for the inhibitory deficit theory of cognitive aging, which predicts that old adults should be more susceptible to auditory distraction than are young adults.     

Standardization systems as indicators of mental, cultural and socio-economic states

Standardization processes under the aegis of standards bodies in different geographic domains exhibit similar institutional features, such as the consensus principle in decision making. Nevertheless, among national and regional standardization systems there are significant differences that primarily refer to different attitudes that actors in the respective domains hold towards standardization. Furthermore, these differences in attitude are the result of different cultural, socio-economic and even mental states. Using an institutional approach, this paper argues that the state of standardization system may serve as an indicator of the respective overall mental, cultural and social-economic states in different domains. The authors are indebted to Henk de Vries, Rotterdam School of Management, Netherlands Standardization Institute and Tineke Egyedi and Koen Dittrich, Faculty of Technology, Policy and Management, and an anonymous referee for helpful comments and suggestions.     

On the Role of Fragmentary Knowledge in a Sequence Learning Task

There has been considerable debate about whether or not we need to distinguish between the acquisition of implicit-and, independently thereof, the acquisition of explicit-knowledge in sequence learning tasks. Proponents of the view that a unitary knowledge base is formed assume (a) that the knowledge acquired is explicitly available, and (b) that information about sequence fragments forms the core of this explicit knowledge. Both of these issues are addressed empirically in the present article. In two experiments, an adapted process dissociation procedure and a suitable measurement model were used to separate recollective (explicit) and fluency-based (implicit) memory processes in a sequence learning task. Experiment 1 demonstrated that fluency-based processes came into play much later than recollective processes. Such recollective processes have been conceptualized as being based on simple knowledge about sequence fragments or chunks. Indeed, Experiment 2 showed that recollective processes are more likely to contribute to sequence judgements if chunks are readily available at test than if they are not. Together, these results are in line with the view that the learning of an event systematicity can be conceived of as the memorization of chunks of events that support both the speedingup of reaction times to systematic events and explicit, recollective memory processes even after relatively little training.     

Syntactic parsing as revealed by brain responses: First-pass and second-pass parsing processes

This paper reviews a series of electrophysiological experiments on syntactic processing against the background of a psycholinguistic two-stage model of parsing. The data reveal two event-related brain potential components in correlation with syntactic processes: an early left anterior negativity and a late centro-parietal positivity. It is argued that these two components can be correlated with two separate stages of syntactic processing: the early left anterior negativity reflecting first-pass parsing processes and the late positivity reflecting second-pass parsing processes possibly including processes of reanalyses.
