Regression toward the mean or heuristic processing in detecting deception? Reply to Elaad (2010)

Masip, et al. (2009) conducted a study in which observers had to make truth-lie judgments at the beginning, middle, or end of a series of videotaped statements. They found a decline in truth judgments over time and explained this finding in terms of information processing mode. Recently, Elaad (2010) challenged this explanation and contended that the decline could be a result of regression toward the mean. In the present paper, it is argued that because Masip, et al. took multiple Moment 1 judgments over time and then averaged across judgments, regression toward the mean was extremely unlikely. Furthermore, the decrease in truth judgments was found under several separate conditions; this cannot be explained by random fluctuations alone. Finally, Masip, et al.'s data were re-analyzed adjusting for the effects of regression toward the mean. The outcomes of these analyses were the same as those reported in the original article.     

Transperformative education: Toward a new educational paradigm based on transdisciplinarity and artistic performativity

The study we are presenting in this article is based on an analysis of the critical observations of the state of the art of the prevailing educational systems today through evaluations by institutions like the United Nations Educational, Scientific and Cultural Organization (UNESCO) and the Organisation for Economic Co-Operation and Development and the logical demand for reform that they call for. As a consequence, we posit an approach to the construction of an educational paradigm based on performative education that draws from performance art, transdisciplinary methodology, and a survey of the specialized literature that frames the epistemological and methodological field of education in complex, ever-changing settings. The methodology used is a heuristic comparison in a pedagogical sense that, based on our analysis of state of the art publications from the educational system, outlines the transfer of the characteristics of performance art and transdisciplinary methodology to the model we call Transperformative Education. As a result of this model, we came up with a proposal for a deep-seated paradigmatic shift that entails everything from the modification of institutional educational policies to the ways of teaching and learning, including, of course, a major challenge: a shift in the direction of educational research.     

Performance in Autobiographical Memory of Older Adults with Depression Symptoms

The aim of this study was to compare the performance in the Autobiographical Memory Test in older adults with high scores on depression symptoms (HDS) compared with a matched group with low scores on depression symptoms (LDS) according to the clinical cut‐off of the Centre for Epidemiological Studies Depression Scale. Participants were asked to generate specific autobiographical memories in response to a series of positive and negative cue words. Latencies of responses for each item were also scored. LDS participants showed a higher proportion of specific memories than HDS participants. Latencies of responses to positive and negative cues were greater for HDS than LDS. Specific autobiographical memory was positively associated with Life Satisfaction. Cognitive emotional changes in the function of memory with age are suggested as a possible explanation for the findings. Copyright © 2012 John Wiley & Sons, Ltd.     

‘What Would You Say if You Were Guilty?’ Suspects' Strategies During a Hypothetical Behavior Analysis Interview Concerning a Serious Crime

Previous research has shown that the Behavior Analysis Interview (BAI) indicators of guilt or innocence are merely commonsense notions. In this study, we examined whether this would lead suspects of a serious crime to try to manipulate their behavior during a BAI in order to look innocent. A serious crime was described to 74 undergraduates who were asked to imagine that they were guilty or innocent. They then completed a questionnaire about the strategies that they would use during a BAI. Both guilty and innocent suspects were more willing to show the innocence rather than guilt indicators of the BAI. Innocent suspects had a blind faith in the power of innocence to demonstrate that they were not guilty. The general (non‐BAI) strategies coincided with those of previous studies; this indicates that prior findings on strategies can be generalized to serious crimes and that strategies can be examined with uncomplicated procedures such as the one used in this study.

Learning time-varying categories

Many kinds of objects and events in our world have a strongly time-dependent quality. However, most theories about concepts and categories either are insensitive to variation over time or treat it as a nuisance factor that produces irrational order effects during learning. In this article, we present two category learning experiments in which we explored peoples’ ability to learn categories whose structure is strongly time-dependent. We suggest that order effects in categorization may in part reflect a sensitivity to changing environments, and that understanding dynamically changing concepts is an important part of developing a full account of human categorization.     

Quality adjusted survival analysis: A neglected application of the quality of well-being scale

Abstract

Background In survival analysis, those who are alive are statistically coded as 1.0 while those who are dead are coded as 0.0. Since everyone who remains alive is given the same score, a person confined to bed with an irreversible coma is alive and is counted the same as someone who is active and asymtomatic. The Quality of Well-being (QWB) scale defines levels of wellness on the continuum between death and optimum function and integrates morbidity and mortality into the same number. This paper demonstrates the effect of including mortality in QWB estimates for male adults with HIV infection.

Method This study involves follow-up of a cohort of 386 male adults participating in the San Diego HIV Neurobehavioral Research Center (HNRC). Patients were evaluated using the QWB at enrollment and at six month intervals. All patients were classified into three stages of HIV disease according to the Center for Disease Control (CDC) classification: CDC IV (symptomatic HIV disease), CDC II or III (asymptomatic infection) and uninfected male controls.

Results QWB scores were calculated with and without mortality included for men in each CDC class who completed a one year (N = 148) or two year follow-up (N = 60). At each evaluation, there were significant differences among CDC classes and inclusion of deaths increased the variance accounted for by CDC class at each evaluation.

Conclusions HIV infection has significant impacts upon both morbidity and mortality. Survival analysis captures only the mortality dimension, while quality adjusted survival analysis using the QWB includes both dimensions. We propose quality adjusted survival analysis as a more sensitive method for assessing outcome in HIV disease and other health conditions.     

The socialization of the gifts of tongues and healing in Mexican Pentecostalism

Mexican Pentecostalism emphasizes both speaking in tongues and faith healing as religious manifestations which believers should have. Although they are considered to be given by the Holy Spirit, these practices imply a socialization with the collective of followers. The analysis of pentecostal groups in the urban environment of Mexico City and in the rural Totonac Indian communities shows that these religious practices and beliefs are very similar in the two areas mentioned. It is necessary for the pentecostal believer to learn the ‘proper’ way to speak in tongues and to heal the sick, in order to separate followers from other religions which compete with pentecostalism by offering ritual possession and alternative forms of curing human suffering. In Mexico, popular spiritualism, the Catholic charismatic movement and traditional Indian curers all offer direct competition for pentecostalism. The religious mobility further complicates this situation. The important role of public discourse and testimony is also dealt with here.     

Predictive model for early math skills based on structural equations

Early math skills are determined by higher cognitive processes that are particularly important for acquiring and developing skills during a child's early education. Such processes could be a critical target for identifying students at risk for math learning difficulties. Few studies have considered the use of a structural equation method to rationalize these relations. Participating in this study were 207 preschool students ages 59 to 72 months, 108 boys and 99 girls. Performance with respect to early math skills, early literacy, general intelligence, working memory, and short‐term memory was assessed. A structural equation model explaining 64.3% of the variance in early math skills was applied. Early literacy exhibited the highest statistical significance (β = 0.443, p < 0.05), followed by intelligence (β = 0.286, p < 0.05), working memory (β = 0.220, p < 0.05), and short‐term memory (β = 0.213, p < 0.05). Correlations between the independent variables were also significant (p < 0.05). According to the results, cognitive variables should be included in remedial intervention programs.
