Effects of Personalized Banner Ads on Visual Attention and Recognition Memory

Internet companies collect a vast amount of data about their users in order to personalize banner ads. However, very little is known about the effects of personalized banners on attention and memory. In the present study, 48 subjects performed search tasks on web pages containing personalized or nonpersonalized banners. Overt attention was measured by an eye‐tracker, and recognition of banner and task‐relevant information was subsequently examined. The entropy of fixations served as a measure for the overall exploration of web pages. Results confirm the hypotheses that personalization enhances recognition for the content of banners while the effect on attention was weaker and partially nonsignificant. In contrast, overall exploration of web pages and recognition of task‐relevant information was not influenced. The temporal course of fixations revealed that visual exploration of banners typically proceeds from the picture to the logo and finally to the slogan. We discuss theoretical and practical implications. Copyright © 2014 John Wiley & Sons, Ltd.     

Dissociation of rapid response learning and facilitation in perceptual and conceptual networks of person recognition

Repetition priming is a prominent example of non‐declarative memory, and it increases the accuracy and speed of responses to repeatedly processed stimuli. Major long‐hold memory theories posit that repetition priming results from facilitation within perceptual and conceptual networks for stimulus recognition and categorization. Stimuli can also be bound to particular responses, and it has recently been suggested that this rapid response learning, not network facilitation, provides a sound theory of priming of object recognition. Here, we addressed the relevance of network facilitation and rapid response learning for priming of person recognition with a view to advance general theories of priming. In four experiments, participants performed conceptual decisions like occupation or nationality judgments for famous faces. The magnitude of rapid response learning varied across experiments, and rapid response learning co‐occurred and interacted with facilitation in perceptual and conceptual networks. These findings indicate that rapid response learning and facilitation in perceptual and conceptual networks are complementary rather than competing theories of priming. Thus, future memory theories need to incorporate both rapid response learning and network facilitation as individual facets of priming.     

Dual Identification and the (De‐)Politicization of Migrants: Longitudinal and Comparative Evidence

The article examines the role of dual identification with both the ethnocultural ingroup and the society of residence in the politicization of migrants. The researchers employed a longitudinal and comparative research design with members of the two largest, but sociologically very different, migrant groups in Germany as research participants (i.e. Turkish migrants and Russian migrants). In line with prior work that has shown that, among members of aggrieved groups, dual identity functions as a politicized collective identity, we found that dual identification fostered political engagement among Turkish migrants. In contrast, Russian migrants reported no substantial grievances, and dual identification negatively affected their subsequent political engagement. The contributions of these findings to an articulation of research on politicization with research on intergroup conflict and a more comprehensive understanding of political phenomena driven by dual identification are discussed.

Testing the Mental Model Theory of Propositional Reasoning

Johnson-Laird, Byrne, and Schaeken (1992) present a theory of propositional reasoning by mental models. The present study provides a comprehensive test of the predictions of that theory for the difficulty of simple disjunctive and conditional inferences. The results are largely consistent with the complex pattern of predictions. They are discussed in the light of recently proposed modifications of the original theory.     

Gamma activity in human EEG is related to highspeed memory comparisons during object selective attention

Among the most important processes of the brain in order to correctly perceive the outside world and act within it are binding, attention, and memory. All three functional mechanisms have been associated with brain activity in the gamma frequency range. It needs to be clarified, however, which subprocesses within the gamma frequency range relate to which perceptual or cognitive functions. In a visual discrimination task, we used Kanizsa figures whose constituent inducer disks need to be bound together to perceive the illusory contours. By a variation of the task requirements we manipulated the allocation of object selective attention as compared to a previous study. One out of four objects had to be detected. This detection process requires the comparison of two object dimensions (form and collinearity) with a working memory template. In order to get behavioural and electrophysiological measures, EEG and reaction times were recorded from 16 and 10 subjects, respectively. We demonstrated that the early evoked gamma activity reflects the process of allocating attention to a selected object as early as 50-150 ms after stimulus onset. We propose that the underlying mechanism is a high-speed memory comparison. In addition, we show that this early gamma activity also determines the reaction times needed to respond to the different stimuli.     

Working Memory Involvement in Propositional and Spatial Reasoning

Four experiments assessed the relative involvement of different working memory components in two types of reasoning tasks: propositional and spatial reasoning. Using the secondary-task methodology, visual, central-executive, and phonological loads were realised. Although the involvement of visuospatial resources in propositional reasoning has traditionally been considered to be small, an overall analysis of the present data suggests an alternative account. A theoretical analysis of the pattern of results in terms of Evans' (1984, 1989) twostage theory of reasoning is proposed and tested in Experiments 3 and 4, in which direct evidence for the alternative account was obtained: significant disruption of propositional reasoning by a concurrent spatial load.     

„Peak Oil“

Scientific prognoses augur the advent of “Peak Oil”, or maximum possible global oil production, in our time. After this maximum, production rates will begin to drop due to increasing capillary pressure in rock deposits, and new discoveries will be unable to compensate for the additive drop in production rates. At the same time, a global increase in energy consumption is also predicted. It is to be expected that the discrepancy between production and demand (heat, mobility, oil-based chemicals) will lead to political destabilisation not only between the “industrial” and “developing” nations, but also in democratic systems. Like the biblical “mene tekel”, “Peak Oil” may be interpreted psychoanalytically as another ecological omen which should arouse civilization to ward off coming disaster. Up to now, psychoanalysts have dealt only sparingly with this perspective. The wake-up call of scientists and publicists in the media has prompted little reaction among consumers and decision-makers. Instead, utopian and/or apocalyptic visions of the future are the order of the day. In correspondence with the Airbus motto: “We must use the air to preserve the earth”, a project of the Max Planck Society is working on “flying automobiles”. In view of these phenomena, our paper presents for discussion the hypothesis of a collective manic denial with splitting of the ego. We try here to limit psychoanalytic speculations with a clinical vignette. It may be asked to what extent the psychoanalytic method – in matters of ecological reality – runs the risk today of entering into collusion with the above-mentioned collective denial, instead of working through it lege artis on the basis of the reality principle.     

No Justification for Lottery Losers

Igor Douven has recently developed a challenge for accounts of justification according to which beliefs about lottery losers are never justified. This article argues that champions of such accounts can rise to Douven's challenge and, what's more, that they can turn Douven's argument around in the sense that they can legitimately take it to provide a vindication of their preferred view.
