Morphological processing during visual word recognition in developing readers: evidence from masked priming

Masked priming studies with adult readers have provided evidence for a form-based morpho-orthographic segmentation mechanism that "blindly" decomposes any word with the appearance of morphological complexity. The present studies investigated whether evidence for structural morphological decomposition can be obtained with developing readers. We used a masked primed lexical decision design first adopted by Rastle, Davis, and New (2004), comparing truly suffixed (golden-GOLD) and pseudosuffixed (mother-MOTH) prime-target pairs with nonsuffixed controls (spinach-SPIN). Experiment 1 tested adult readers, showing that priming from both pseudo- and truly suffixed primes could be obtained using our own set of high-frequency word materials. Experiment 2 assessed a group of Year 3 and Year 5 children, but priming only occurred when prime and target shared a true morphological relationship, and not when the relationship was pseudomorphological. This pattern of results indicates that morpho-orthographic decomposition mechanisms do not become automatized until a relatively late stage in reading development.     

Behavior Matching in Multimodal Communication Is Synchronized

A variety of theoretical frameworks predict the resemblance of behaviors between two people engaged in communication, in the form of coordination, mimicry, or alignment. However, little is known about the time course of the behavior matching, even though there is evidence that dyads synchronize oscillatory motions (e.g., postural sway). This study examined the temporal structure of nonoscillatory actions—language, facial, and gestural behaviors—produced during a route communication task. The focus was the temporal relationship between matching behaviors in the interlocutors (e.g., facial behavior in one interlocutor vs. the same facial behavior in the other interlocutor). Cross‐recurrence analysis revealed that within each category tested (language, facial, gestural), interlocutors synchronized matching behaviors, at temporal lags short enough to provide imitation of one interlocutor by the other, from one conversational turn to the next. Both social and cognitive variables predicted the degree of temporal organization. These findings suggest that the temporal structure of matching behaviors provides low‐level and low‐cost resources for human interaction.     

Religious diversity and epistemic luck

A familiar criticism of religious belief starts from the claim that a typical religious believer holds the particular religious beliefs she does just because she happened to be raised in a certain cultural setting rather than some other. This claim is commonly thought to have damaging epistemological consequences for religious beliefs, and one can find statements of an argument in this vicinity in the writings of John Stuart Mill and more recently Philip Kitcher, although the argument is seldom spelled out very precisely. This paper begins by offering a reconstruction of an argument against religious beliefs from cultural contingency, which proceeds by way of an initial argument to the unreliability of the processes by which religious beliefs are formed, whose conclusion is then used to derive two further conclusions, one which targets knowledge and the other, rationality. Drawing upon recent work in analytic epistemology, I explore a number of possible ways of spelling out the closely related notions of accidental truth, epistemic luck, and reliability upon which the argument turns. I try to show that the renderings of the argument that succeed in securing the sceptical conclusion against religious beliefs also threaten scepticism about various sorts of beliefs besides religious beliefs.     

ÉMIGRÉS AS TRANSMITTERS OF AMERICAN PROTEST CULTURE

This essay challenges scholarly claims that the German student movement represented the emergence of latent fascist and anti-Semitic tendencies, especially when its target was the US war in Vietnam. Instead, the author argues that Jewish voices were prominent in the German Sixties through the writings of émigré intellectuals such as Max Horkheimer and Herbert Marcuse, as well as the poet Erich Fried, who inspired student activists even as they took disparate positions on the war. Moreover, Jewish Americans who were strongly represented in the American New Left groups served as a model for German student activists. Rather than anti-Semitism, we see cosmopolitanism at work in 1968.     

Early evidence affects later decisions: Why evidence accumulation is required to explain response time data

Models of decision making differ in how they treat early evidence as it recedes in time. Standard models, such as the drift diffusion model, assume that evidence is gradually accumulated until it reaches a boundary and a decision is initiated. One recent model, the urgency gating model, has proposed that decision making does not require the accumulation of evidence at all. Instead, accumulation could be replaced by a simple urgency factor that scales with time. To distinguish between these fundamentally different accounts of decision making, we performed an experiment in which we manipulated the presence, duration, and valence of early evidence. We simulated the associated response time and error rate predictions from the drift diffusion model and the urgency gating model, fitting the models to the empirical data. The drift diffusion model predicted that variations in the evidence presented early in the trial would affect decisions later in that same trial. The urgency gating model predicted that none of these variations would have any effect. The behavioral data showed clear effects of early evidence on the subsequent decisions, in a manner consistent with the drift diffusion model. Our results cannot be explained by the urgency gating model, and they provide support for an evidence accumulation account of perceptual decision making.     

Suicide attempts: Patients with and without an affective disorder show impaired autobiographical memory specificity

A number of studies have shown reduced recall of specific autobiographical memories (AMs) in patients after attempted suicide, but in all of them the study samples were confounded with diagnoses of affective disorders. The present study aims to demonstrate impaired specific autobiographical memory in patients after a suicide attempt without a diagnosis of an affective disorder. Four groups were compared: (1) patients with an actual major depression and a suicide attempt; (2) patients after a suicide attempt without a lifetime history of an affective diagnosis; (3) patients currently suffering from major depression without a suicide attempt; and (4) control persons not suffering from either of the two conditions during their entire life. Individuals with major depression and a suicide attempt showed reduced specificity of AM and, most importantly, patients with a suicide attempt—despite the absence of an affective disorder—were equally impaired with recall of specific AMs as were patients with major depression. The authors propose that reduced specific AM is a common vulnerability factor that can lead either to the development of an affective disorder and/or to a suicide attempt.     

The role of the self‐fulfilling prophecy in young adolescents' responsiveness to a substance use prevention program

This research examined whether naturally occurring self‐fulfilling prophecies influenced adolescents' responsiveness to a substance use prevention program. The authors addressed this issue with a unique methodological approach that was designed to enhance the internal validity of research on naturally occurring self‐fulfilling prophecies by experimentally controlling for prediction without influence. Participants were 321 families who were assigned to an adolescent substance use prevention program that either did or did not systematically involve parents. Results showed that parents' perceptions about the value of involving parents in adolescent substance use prevention predicted adolescents' alcohol use more strongly among families assigned to the prevention program that systematically involved parents than to the one that did not. The theoretical and practical implications of these findings are discussed.     

The Rat: A Study in Behavior by S. A. Barnett

This paper attempts to provide a helpful, “hands-on” guide to leaders of psychotherapy groups in a manner that is free of any one particular theoretical orientation. It focuses on characteristics that can be applied to groups emphasizing life skills, cognitive skills, or interpersonal skills in a variety of settings and types of groups—inpatient or outpatient, short or long term. Issues covered include the importance of structure as it relates to anxiety, group composition, skill requirements, resistance, and symbolic factors. The major theme is that leaders need to make choices and that these choices can be made easier with an awareness of the major factors involved in group psychotherapy.
