A methodological investigation of the Intermodal Preferential Looking paradigm: Methods of analyses,picture selection and data rejection criteria

The Intermodal Preferential Looking paradigm provides a sensitive measure of a child's online word comprehension. To complement existing recommendations (Fernald, Zangl, Portillo, & Marchman, 2008), the present study evaluates the impact of experimental noise generated by two aspects of the visual stimuli on the robustness of familiar word recognition with and without mispronunciations: the presence of a central fixation point and the level of visual noise in the pictures (as measured by luminance saliency). Twenty-month-old infants were presented with a classic word recognition IPL procedure in 3 conditions: without a fixation stimulus (No Fixation – noisiest condition), with a fixation stimulus before trial onset (Fixation, intermediate), and with a fixation stimulus, a neutral background and equally salient images (Fixation Plus – least noisy). Data were systematically analyzed considering a range of data selection criteria and dependent variables (proportion of looking time towards the target, longest look, and time-course analysis). Critically, the expected pronunciation and naming interaction was only found in the Fixation Plus condition. We discuss the impact of data selection criteria and the dependent variable choice on the modulation of these effects across the different conditions.     

When the Solution Is on the Doorstep: Better Solving Performance,but Diminished Aha! Experience for Chess Experts on the Mutilated Checkerboard Problem

Insight problems are difficult because the initially activated knowledge hinders successful solving. The crucial information needed for a solution is often so far removed that gaining access to it through restructuring leads to the subjective experience of “Aha!”. Although this assumption is shared by most insight theories, there is little empirical evidence for the connection between the necessity of restructuring an incorrect problem representation and the Aha! experience. Here, we demonstrate a rare case where previous knowledge facilitates the solving of insight problems but reduces the accompanying Aha! experience. Chess players were more successful than non‐chess players at solving the mutilated checkerboard insight problem, which requires retrieval of chess‐related information about the color of the squares. Their success came at a price, since they reported a diminished Aha! experience compared to controls. Chess players’ problem‐solving ability was confined to that particular problem, since they struggled to a similar degree to non‐chess players to solve another insight problem (the eight‐coin problem), which does not require chess‐related information for a solution. Here, chess players and non‐chess players experienced the same degree of insight.

Network Analysis in Community Psychology: Looking Back,Looking Forward

Network analysis holds promise for community psychology given the field's aim to understand the interplay between individuals and their social contexts. Indeed, because network analysis focuses explicitly on patterns of relationships between actors, its theories and methods are inherently extra‐individual in nature and particularly well suited to characterizing social contexts. But, to what extent has community psychology taken advantage of this network analysis as a tool for capturing context? To answer these questions, this study provides a review of the use network analysis in articles published in American Journal of Community Psychology . Looking back, we describe and summarize the ways that network analysis has been employed in community psychology research to understand the range of ways community psychologists have found the technique helpful. Looking forward and paying particular attention to analytic issues identified in past applications, we provide some recommendations drawn from the network analysis literature to facilitate future applications of network analysis in community psychology.

Assumed similarity in personality within intimate relationships

Assumed similarity is the tendency to assume that another person is similar to oneself. The present studies examined assumed similarity in intimate relationships regarding the HEXACO personality traits in Denmark (N = 93) and China (N = 236). Specifically, these studies hypothesized that people assume higher similarity with their intimate partners in Honesty‐Humility and Openness to Experience compared to the other four HEXACO traits (Emotionality, Extraversion, Agreeableness, and Conscientiousness). Results from both studies indicate that assumed similarity was higher in Honesty‐Humility compared to Emotionality, Extraversion, Agreeableness, and Conscientiousness. However, assumed similarity in Openness was higher compared to Emotionality and Conscientiousness only. Supplementary analyses indicate no cultural differences between Denmark and China in assumed similarity in Honesty‐Humility and Openness.     

Transport risk evaluations associated with past exposure to adverse security events in public transport

The current study aims to examine differences in risk evaluations according to whether individuals have been exposed to adverse security events in transport during the last five years. In addition, a path model is tested where risk evaluations predict intentions to use public transport and use of such transport in these groups. The results are based on a survey conducted in a randomly obtained representative sample of the Norwegian urban public (n = 1043). The results showed that individuals who had been exposed to adverse security events in public transport reported substantially higher risk perception of experiencing security issues in such transport than those who were not exposed. Exposed individuals also reported higher probability judgements and more worry of experiencing injury in public transport. The path model showed that high probability judgements of experiencing injury in public transport were related to a lower intention of using such transport, whereas corresponding worry in the private motorized sector predicted a stronger intention to use public transport. Demand for risk mitigation in the public transport sector was found to be more relevant for intentions to use public transport than similar demands in the private motorized sector. The path model and coefficients were not found to differ significantly according to exposure to security events in public transport. The findings are discussed in relation to the role of negative risk experiences for risk evaluations in transport.     

Accounting for fluctuations in body dissatisfaction

The present study evaluated whether the strength of relationship between contextual cues (presence of company and mood) and state body dissatisfaction varied as a function of individual differences in key trait measures (body shame, body surveillance tendencies, internalization of appearance standards, and trait affect) which have been linked to trait body dissatisfaction. Fifty-five undergraduate women completed a questionnaire containing the trait-based measures and then carried a Personal Digital Assistant (PDA) for a 7-day period. The PDA prompted participants six times daily to self-report their current mood and state body dissatisfaction. Multi-level modeling revealed that individual differences in body shame predicted inter-individual variability in the strength of the relationships between presence of company and state body dissatisfaction, and positive mood and state body dissatisfaction. Trait positive affect also explained variance in the positive mood state-body dissatisfaction relationship. The implications of the findings for prevention of body image disturbances are discussed.     

Being there when it happens: A novel approach to sampling reflectively observed experience

Examining a number of recently developed methods for acquiring first-person data on consciousness, we detect a lack of sensitivity for distinguishing the experiential moments in which the experiencing person was reflectively attending to her ongoing experience. In order to address this gap, we introduce a novel research format for obtaining data on lived experience, combining random sampling of experience with a subsequent retrospective examination of acquired samples in the form of dialogical phenomenological inquiry. The proposed approach aims at the examination of reflectively observed experiential moments and is based on researchers’ iterative cultivation of the phenomenological attitude. Drawing upon results from a longitudinal study of the potential of meditation as a tool for examining consciousness, we address the epistemological and methodological challenges of the proposed approach, discuss its applicability and research potential, as well as examine the characteristics and validity of phenomenal data thus acquired.     

Toward A New Eternalist Paradigm for Afterlife Studies: The Case of the Near-Death Experiences Argument

In contemporary Western culture, death has been widely censured because of its conceptual implications; it lies at the boundaries between reductionism and metaphysics. There is not yet an efficacious epistemology able to solve this contraposition and its consequent collision with science and tradition. This article analyzes Near Death Experiences (NDEs) as a prototypical argument in which the two perspectives conflict. Specifically, it analyzes the epistemological antinomies of the ontological representations of death, inhering in passage versus absolute annihilation. Indeed, the NDEs theme permits the examination of the logical contradiction between monistic reductionism and its ontological counterpart to improve the discovery of a new paradigm that integrates the ecological with eternalist views.
