'The repression and the return of bad objects': W. R. D. Fairbairn and the historical roots of theory

One of the seminal, if solitary, figures of the British Object Relations School was the Scotsman W. R. D. Fairbairn. In this paper the author relates some of the distinctive features of Fairbairn's thinking to traumatic aspects of his country's history, especially the harsh, repressive traditions of Scottish Presbyterianism, which were magnified in confusing ways by his sexually puritanical parents. The two World Wars are shown to have played an important role in liberating Fairbairn from these constraints, influencing both his choice of career and, notably, the evolution of his ideas.     

The Effect of Cane Use on Attentional Demands During Walking

We investigated the effects of cane use, lateral walking stability, and cane use practice on attentional demands during walking. Attentional demands were assessed using dual-task methodology with a reaction time (RT) task. Sixteen healthy young subjects performed the RT task during walking, before and after cane use practice under four conditions: with/without cane use while wearing normal/unstable shoes. Among normal shoe conditions, cane use resulted in longer RTs. In contrast, RTs were similar regardless of cane use in the unstable shoe conditions. Among conditions without cane use, unstable shoes resulted in longer RTs. In contrast, RTs were similar regardless of shoe type in the cane use conditions. This study suggests that using a cane during walking requires additional attention; however, the resulting attentional demands depend on walking stability.     

Modeling implicit learning in a cross-modal audio-visual serial reaction time task

This study examined implicit learning in a cross-modal condition, where visual and auditory stimuli were presented in an alternating fashion. Each cross-modal transition occurred with a probability of 0.85, enabling participants to gain a reaction time benefit by learning the cross-modal predictive information between colors and tones. Motor responses were randomly remapped to ensure that pure perceptual learning took place. The effect for the implicit learning was extracted from the data by fitting five different models to the data, which was highly variable due to motor variability. To examine individual learning rates for stimulus types of different discriminability and modality, the models were fitted per stimulus type and individually for each participant. The model selection identified the model that included motor variability, surprise effects for deviants and a serial position for effect onset as the most explanatory (Akaike weight 0.87). Further, there was a significant global cross-modal implicit learning effect for predictable versus deviant transitions (40 ms reaction time difference, p < 0.004). The learning rates over time differed for both modality and the stimuli within modalities, although there was no correlation to global error rates or reaction time differences between the stimulus types. These results demonstrate a modeling method that is well suited to extract detailed information about the success of implicit learning from high variability data. It further shows a cross-modal implicit learning effect, which extends the understanding of the implicit learning system and highlights the possibility for information to be processed in a cross-modal representation without conscious processing.     

项目反应时间的对数偏正态模型

近年来,项目反应时间数据的建模是心理和教育测量领域的热门方向之一。针对反应时间的对数正态模型和Box-Cox正态模型的不足,本文在van der Linden的分层模型框架下基于偏正态分布建立一个反应时间的对数线性模型,并成功给出模型参数估计的马尔科夫链蒙特卡罗（Markov Chain Monte Carlo, MCMC）算法。模拟研究和实例分析的结果均表明,与对数正态模型和Box-Cox正态模型相比,对数偏正态模型表现出更加优良的拟合效果,具有更强的灵活性和适用性。     

On the dissociation between reaction time and response duration as a function of lexical and sublexical reading: An examination of phonetic decoding and computational models

Neurobiological models of reading account for two ways in which orthography is converted to phonology: (1) familiar words, particularly those with exceptional spelling-sound mappings (e.g., shoe) access their whole-word lexical representations in the ventral visual stream, and (2) orthographically unfamiliar words, particularly those with regular spelling-sound mappings (i.e., pseudohomophones [PHs], which are orthographically novel but sound like real words; e.g., shue) are phonetically decoded via sublexical processing in the dorsal visual stream. The present study used a naming task in order to compare naming reaction time (RT) and response duration (RD) of exception and regular words to their PH counterparts. We replicated our earlier findings with words, and extended them to PH phonetic decoding by showing a similar effect on RT and RD of matched PHs. Given that the shorter RDs for exception words can be attributed to the benefit of whole-word processing in the orthographic word system, and the longer RTs for exception words to the conflict with phonetic decoding, our PH results demonstrate that phonetic decoding also involves top-down feedback from phonological lexical representations (e.g., activated by shue) to the orthographic representations of the corresponding correct word (e.g., shoe). Two computational models were tested for their ability to account for these effects: the DRC and the CDP+. The CDP+ fared best as it was capable of simulating both the regularity and stimulus type effect on RT for both word and PH identification, although not their over-additive interaction. Our results demonstrate that both lexical reading and phonetic decoding elicit a regularity dissociation between RT and RD that provides important constraints to all models of reading, and that phonetic decoding results in top-down feedback that bolsters the orthographic lexical reading process.     

Bridging novelty and familiarity-based recognition memory: A matter of timing

Novelty detection is essential to adapt to changes. However, the relationship between novelty detection and visual recognition memory remains unclear. To characterize the temporal dynamics of novelty and its connection to familiarity, we probed early behavioural performance of novelty and familiarity in 31 participants using a speeded go/no-go recognition task with a 600-ms response deadline. Responses to familiarity and novelty produced symmetrical biases and correlated accuracies and biases, but novelty decisions were less accurate and had slower minimal reaction times (410?ms). These processes thus appear to be independent, as suggested by a more efficient system in the case of familiarity, but with common factors bringing overlapping contributions to both processes. This may possibly be explained by the more fluent processing of repeated stimuli, but with familiarity and novelty potentially relying on one decision criterion, as suggested by the correlated and remarkably symmetrical biases. This study supports models that conceptualize novelty and familiarity decisions as two partly overlapping processes.     

The destruction of time in pathological narcissism

This paper describes the characteristics of subjective time (in contrast to objective time), with particular reference to a specific form of pathological experience and relation to the passage of time in patients with narcissistic personality undergoing psychoanalytic treatment. The clinical manifestations and technical approach to this pathology of time experience are outlined in the context of illustrative clinical vignettes.     

Avoiding certain frustration, reflection, and the cable guy paradox

We discuss the cable guy paradox, both as an object of interest in its own right and as something which can be used to illuminate certain issues in the theories of rational choice and belief. We argue that a crucial principle—The Avoid Certain Frustration (ACF) principle—which is used in stating the paradox is false, thus resolving the paradox. We also explain how the paradox gives us new insight into issues related to the Reflection principle. Our general thesis is that principles that base your current opinions on your current opinions about your future opinions need not make reference to the particular times in the future at which you believe you will have those opinions, but they do need to make reference to the particular degrees of belief you believe you will have in the future.

The Differential Influence of Lexical Parameters on Naming Latencies in German. A Study on Noun and Verb Picture Naming

The present study investigates the effects of word category (nouns versus verbs) and their subcategories on naming latencies in German, with a focus on the influence of lexical parameters on naming performance. The experimental material met linguistic construction criteria and was carefully matched for age of spontaneous production, frequency, and name agreement. Additional lexical parameters (objective age-of-acquisition, word length, visual complexity, imageability) were obtained. The results demonstrated a clear effect of word category on naming latencies. This effect was supported by two different observations. First, there was evidence for category and subcategory effects in naming: nouns were named faster than verbs, and intransitive verbs were named faster than transitive verbs. Second, while objective age-of-acquisition (naming age) turned out to be an important predictor of reaction times for both word categories, naming latencies for nouns and verbs were affected differentially by other lexical parameters. The results are discussed with respect to current controversies on the noun-verb-asymmetry.
