ERP responses to images of abstract artworks,photographs of natural scenes,and artificially created uncomfortable images

The idea of efficient coding in the visual brain allows for predictions for the processing of various types of images, including certain artworks, natural images and uncomfortable images. Efficient processing is thought to result in lower responses compared to less efficient processing. The efficiency of the processing is suggested to depend on the architecture of the visual system and the properties of the input image. In this study, neural responses were estimated using EEG across the categories of a set of five images of abstract artworks, a set of five photographs of natural images and a set of five computer-generated uncomfortable images. EEG responses to contrast-matched images were found to be lower for the set of five abstract artworks used in the study compared to the set of photographs of natural images, lending preliminary support for the idea that certain abstract artworks, for example the work of Pollock, may be processed efficiently.     

Complexity of categorical syllogisms: An integration of two metrics

The complexity of categorical syllogisms was assessed using the relational complexity metric, which is based on the number of entities that are related in a single cognitive representation. This was compared with number of mental models in an experiment in which adult participants solved all 64 syllogisms. Both metrics accounted for similarly large proportions of the variance, showing that complexity depends on the number of categories that are related in a representation of the combined premises, whether represented in multiple mental models, or by a single model. This obviates the difficulty with mental models theory due to equivocal evidence for construction of more than one mental model. The “no valid conclusion” response was used for complex syllogisms that had valid conclusions. The results are interpreted as showing that the relational complexity metric can be applied to syllogistic reasoning, and can be integrated with mental models theory, which together account for a wide range of cognitive performances.     

An Applied Example of Pooled Time Series Analysis: Cardiovascular Reactivity to Stressors in Children With Autism

The advent of telemetric devices that sample data extensively over time has facilitated single subject or idiographic research to intensively study a single person over time. One of the challenges of idiographic research is combining single subject results to determine generalizability across subjects. This article demonstrates the first behavioral science application of pooled time series analysis, an extension of time series analysis that allows for the testing of between-person effects. The analysis used cardiovascular data gathered from 4 children with autism between the ages of 10 and 20 while exposed to 6 experimentally manipulated environmental stressors. A pooled time series analysis using the general transformation approach identified 1 general (a difficult learning task) and 3 specific stressors (exposure to a loud noise, unstructured time, and eating a preferred food) across the 4 participants. This application of pooled time series analysis demonstrates the challenges and potential for this method to address the issue of generalizability when using an idiographic research approach in the behavioral sciences.     

Mental imagery as an emotional amplifier: application to bipolar disorder

Cognitions in the form of mental images have a more powerful impact on emotion than their verbal counterparts. This review synthesizes the cognitive science of imagery and emotion with transdiagnostic clinical research, yielding novel predictions for the basis of emotional volatility in bipolar disorder. Anxiety is extremely common in patients with bipolar disorder and is associated with increased dysfunction and suicidality, yet it is poorly understood and rarely treated. Mental imagery is a neglected aspect of bipolar anxiety although in anxiety disorders such as posttraumatic stress disorder and social phobia focusing on imagery has been crucial for the development of cognitive behavior therapy (CBT).In this review we present a cognitive model of imagery and emotion applied to bipolar disorder. Within this model mental imagery amplifies emotion, drawing on Clark's cyclical panic model [(1986). A cognitive approach to panic. Behaviour Research and Therapy, 24, 461–470]. We (1) emphasise imagery's amplification of anxiety (cycle one); (2) suggest that imagery amplifies the defining (hypo-) mania of bipolar disorder (cycle two), whereby the overly positive misinterpretation of triggers leads to mood elevation (escalated by imagery), increasing associated beliefs, goals, and action likelihood (all strengthened by imagery).Imagery suggests a unifying explanation for key unexplained features of bipolar disorder: ubiquitous anxiety, mood instability and creativity. Introducing imagery has novel implications for bipolar treatment innovation - an area where CBT improvements are much-needed.     

Emotional arousal and negative affect in marital conflict: the influence of gender,conflict structure,and demand‐withdrawal

This report covers two studies that examined how spouses' emotional arousal and negative affect in response to marital conflict are shaped by gender, conflict structure, and demand‐withdraw communication. In Study 1, 86 couples participated in a video analogue presentation procedure, and in Study 2, 32 couples participated in an observational methodology. In both studies, spouses' evaluative reports of their emotional arousal and negative affect were collected within two experimental conditions in which either the husband's or the wife's issue was discussed. In both studies, husbands—but not wives—reported lower levels of post‐interaction arousal and negative affect in the wife's issue condition than in the husband's issue condition. In both studies, husbands' as well as wives' level of emotional arousal was positively associated with their level of negative affect. In Study 2, husbands who were less demanding and more withdrawing during marital conflict were less aroused after the discussion. In contrast, wives reported more emotional arousal and negative affect as they were more withdrawing and less demanding, respectively. Copyright © 2005 John Wiley & Sons, Ltd.     

Accounting for the Appeal to the Authority of Experts

Work in Argumentation Studies (AS) and Studies in Expertise and Experience (SEE) has been proceeding on converging trajectories, moving from resistance to expert authority to a cautious acceptance of its legitimacy. The two projects are therefore also converging on the need to account for how, in the course of complex and confused civic deliberations, nonexpert citizens can figure out which statements from purported experts deserve their trust. Both projects recognize that nonexperts cannot assess expertise directly; instead, the nonexpert must judge whether to trust the expert. But how is this social judgment accomplished? A normative pragmatic approach from AS can complement and extend the work from SEE on this question, showing that the expert’s putting forward of his view and “bonding” it with his reputation for expertise works to force or “blackmail” his audience of citizens into heeding what he says. Appeals to authority thus produce the visibility and accountability we want for expert views in civic deliberations.     

Future‐focussed thinking: combining scenario planning with decision analysis

This paper first describes current practice in decision analysis and argues that nothing in the technique's application is likely to challenge the strategic decision maker's current worldview of the course of future events that are modelled in the decision tree. By contrast, a scenario planning intervention in an organization has the potential to increase perceived threat and thus lead to a step change in strategic decision making. Strategic decisions are made against a backcloth of the operation of psychological processes that act, it is argued, to reduce the perceived level of environmental threat and result in strategic inertia. For this reason, it is recommended that scenario planning should be adopted as a standard procedure because of its ability to challenge individual and organizational worldviews. The use of scenario planning prior to conventional decision analysis is termed as ‘future‐focussed thinking’, and parallels are drawn between the current advocated approach and that of Keeney's value‐focussed thinking. Both serve to prompt the creation of enhanced options for subsequent evaluation by conventional decision analytic techniques. Copyright © 1999 John Wiley & Sons, Ltd.     

Toward a model of false recall: Experimental manipulation of encoding context and the collection of verbal reports

The likelihood of false recall in the Deese-Roediger-McDermott (DRM) paradigm was shown to depend on encoding context in two experiments. When fillers had been preselected to decrease the likelihood of encoding the critical lure's semantic features, false recall was virtually eliminated. However, when the same words were presented rearranged in different presentation orders, levels of false recall that were found in earlier DRM studies (Robinson & Roediger, 1997) were replicated. The role of encoding processes in the DRM paradigm was further explored with additional participants completing the experiment while thinking aloud. During encoding of word lists, participants verbalized semantic elaboration of the critical lure while studying the word lists. A path analysis demonstrated that participants' verbalization of critical lures during encoding reliably predicted their level of false recall.     

Transitive and pseudo-transitive inferences

Given that A is longer than B, and that B is longer than C, even 5-year-old children can infer that A is longer than C. Theories of reasoning based on formal rules of inference invoke simple axioms ("meaning postulates") to capture such transitive inferences. An alternative theory proposes instead that reasoners construct mental models of the situation described by the premises in order to draw such inferences. An unexpected consequence of the model theory is that if adult reasoners construct simple models of typical situations, then they should infer transitive relations where, in certain cases, none exists. We report four studies corroborating the occurrence of these "pseudo-transitive" fallacies. Experiment 1 established that individuals' diagrams of certain non-transitive relations yield transitive conclusions. Experiment 2 showed that these premises also give rise to fallacious transitive inferences. Experiment 3 established that when the context suggested alternatives to the simple models, the participants made fewer errors. Experiment 4 showed that tense is an important aspect of meaning which affects whether individuals draw transitive conclusions. We discuss the implications of these results for various theories of reasoning.     

Reorganizing the experimentalists: the origins of the society of experimental psychologists

The "Experimentalists," created by E. B. Titchener in 1904, experienced growing pains and other stresses in the 1920s, raising concerns about its future. Those concerns became acute with Titchener's death in 1927. At the 1928 meeting, several "elders," hoping to maintain the group's vigorous advocacy of basic research in the positivist tradition, formed a reorganization committee of 5. The committee expanded to 15, 10 of whom met the following year to debate alternative plans for a new organization. The result was an honorary society for established researchers, the Society of Experimental Psychologists. E. G. Boring's highly personalized 1938 history of the original Experimentalists understated the value of the research contributions made by group members and, by overstating the degree of Titchener's influence, devalued the important contributions of others (e.g., Raymond Dodge).
