The influence of linguistic and cognitive factors on the time course of verb-based implicit causality

In three eye-tracking experiments the influence of the Dutch causal connective “want” (because) and the working memory capacity of readers on the usage of verb-based implicit causality was examined. Experiments 1 and 2 showed that although a causal connective is not required to activate implicit causality information during reading, effects of implicit causality surfaced more rapidly and were more pronounced when a connective was present in the discourse than when it was absent. In addition, Experiment 3 revealed that—in contrast to previous claims—the activation of implicit causality is not a resource-consuming mental operation. Moreover, readers with higher and lower working memory capacities behaved differently in a dual-task situation. Higher span readers were more likely to use implicit causality when they had all their working memory resources at their disposal. Lower span readers showed the opposite pattern as they were more likely to use the implicit causality cue in the case of an additional working memory load. The results emphasize that both linguistic and cognitive factors mediate the impact of implicit causality on text comprehension. The implications of these results are discussed in terms of the ongoing controversies in the literature—that is, the focusing-integration debate and the debates on the source of implicit causality.     

Determinants of memory development in childhood and adolescence

Research on the development of memory has a long history and constitutes one of the most active research areas in the field of cognitive development. In this article, we first describe major historical developments in the literature on children's memory, focusing on systematic research that began in the late 1960s. We then examine new developments in the field, describing four important lines of inquiry: (a) the development of implicit memory, (b) short‐ and long‐term memory development in infancy, (c) longitudinal research on memory strategies and metamemory, and (d) developmental cognitive neuroscience of memory. Finally, promising lines of future research on memory development are briefly discussed.

Drinking to belong: The effect of a friendship threat and self-esteem on college student drinking

The current study examined how implicit and explicit self-esteem and time spent drinking with friends influence college student drinking after a friendship threat manipulation. Poisson regression analyses revealed that students with low implicit self-esteem showed a greater increase in alcohol consumption when drinking with friends after experiencing a friendship threat than in the control condition. These effects were not found among students with high implicit self-esteem. A similar, but weaker, pattern emerged when testing the independent effects of explicit self-esteem. We suggest that low self-esteem students are drinking because they lack the self-resources to deal with unmet belongingness needs. These findings suggest that low implicit self-esteem may be a risk factor for college student drinking.     

THE epistemologies of parsimony: A review of Ockham's razors: A user's manual by Elliott Sober

Sober analyzes two paradigms of parsimony that have been used successfully in science. These are associated with two interpretations of probability: Bayesian and frequentist. Sober applies these paradigms to problems in biology, psychology, and philosophy. In the chapter on psychology, he argues that objective data consisting of environmental input and two or more concurrent responses could be used to refute empirically the radical behaviorist thesis that probability of learned responses can be accounted for solely on the basis of environmental variables. Sober believes that such data are readily available and offers a thought experiment to illustrate his point. Behavior analysts, however, would want actual experimental data, undoubtedly with animals, before accepting any such refutation. Nonetheless, Sober's philosophical point about the type of experiment that would be capable of refuting this thesis is valid. The behavior analytic program, however, does not depend upon the truth of this thesis.     

An attention account of neural priming

Repetition priming of familiar stimuli (e.g., objects) produces a decrease in visual cortical activity for repeated versus novel items, which has been attributed to more fluent processing for repeated items. By contrast, priming of unfamiliar stimuli (e.g., abstract shapes) produces an increase in visual cortical activity. The mechanism for priming-related increases in activity for repeated unfamiliar stimuli is unknown. We hypothesised that such increases in activity may reflect attentional allocation to these items. We tested this hypothesis using a priming-spatial attention paradigm. During Phase 1 of Experiment 1, participants viewed unfamiliar abstract shapes and familiar objects. During Phase 2, participants identified target letters (S or H). Each target letter was preceded by a non-informative shape or object cue that was repeated (from Phase 1) or novel in the same (valid) or opposite (invalid) hemifield. In Experiment 2, we manipulated shape familiarity by presenting shapes once or six times during Phase 1. For both experiments, at valid locations, target identification accuracy was higher following repeated versus novel unfamiliar item cues and lower following repeated versus novel familiar item cues. These findings support our hypothesis that priming-related increases in visual cortical activity for repeated unfamiliar items may, in part, reflect attentional allocation.     

青少年内隐与外显自尊的比较研究

运用两种程序分别测量了青少年的内隐自尊与外显自尊。内隐自尊由内隐联想测验测量,外显自尊由三项自尊量表测量。研究结果表明:在不同年龄阶段与不同性别的青少年中内隐自尊普遍存在;无论是内隐自尊还是外显自尊都不存在显著的性别差异;内隐自尊无显著的年龄差异;外显自尊存在显著的年龄差异,其中高中生比初中生和大学生有更低的外显自尊;内隐自尊与外显自尊之间无显著相关。     

Changing the affective valence of the stimulus items influences the IAT by re-defining the category labels

The Implicit Association Test (IAT; Greenwald, McGhee, & Schwartz, 1998) is a computer-based categorization task that measures concept association strengths. Greenwald et al. (1998) demonstrated that participants completed the categorizations more quickly when pleasant and flower shared a response key than when pleasant and insect shared a response key, and when pleasant and White shared a response key than when pleasant and Black shared a response key. In Study 1, we reversed the typical IAT effect for flowers and insects, and eliminated the typical IAT effect for White and Black, by changing the affective valence of the stimulus items. In Study 2, we replicated the reversibility effect for an animal and plant IAT, and supported a category re-definition hypothesis. Our results have implications for understanding the IAT, and suggest that the IAT not only measures stereotypic responses, but can also be influenced by individuating information of the stimulus items.     

Graph coloring, minimum-diameter partitioning, and the analysis of confusion matrices

It is well known that minimum-diameter partitioning of symmetric dissimilarity matrices can be framed within the context of coloring the vertices of a graph. Although confusion data are typically represented in the form of asymmetric similarity matrices, they are also amenable to a graph-coloring perspective. In this paper, we propose the integration of the minimum-diameter partitioning method with a neighborhood-based coloring approach for analyzing digraphs corresponding to confusion data. This procedure is capable of producing minimum-diameter partitions with the added desirable property that vertices with the same color have similar in-neighborhoods (i.e., directed edges entering the vertex) and out-neighborhoods (i.e., directed edges exiting the vertex) for the digraph corresponding to the minimum partition diameter.
