Towards better computational models of the balance scale task: a reply to Shultz and Takane

In contrast to Shultz and Takane [Shultz, T.R., & Takane, Y. (2007). Rule following and rule use in the balance-scale task. Cognition, in press, doi:10.1016/j.cognition.2006.12.004.] we do not accept that the traditional Rule Assessment Method (RAM) of scoring responses on the balance scale task has advantages over latent class analysis (LCA): RAM is similar to a very restricted form of LCA. The apparent shortcomings of LCA are also less severe than they suggest. Via new simulations we show that LCA detects small classes reliably. We also counter their concerns regarding the torque difference effect and we underline the problems connectionist models have with correctly responding to balance items. Despite these differences in opinion we agree with Shultz and Takane on the possible avenues for future research.     

Coparenting and early conscience development in the family

In the current research, the authors examined children's observed compliance in a family clean-up paradigm and parents' reports of coparenting to predict young children's conscience (e.g., affective discomfort and moral regulation) in a sample of 58 families with two parents and at least two children. The authors found relations between parents' reports of children's conscience development and observer-rated compliance in a family clean-up session, and significant correlations between coparenting and conscience development. There were a greater number of significant results for younger, 2-year-old siblings than for older siblings, which may reflect the importance of the period between 2 and 3 years for the emergence of conscience. Multiple regressions revealed that younger siblings' age, observed compliance/noncompliance, and parents' reports of coparenting were all significant in predicting parents' reports of affective discomfort and moral regulation. Findings underscore the importance of continuing research on whole-family dynamics when studying young children's early conscience and moral regulation.     

Priming meritocracy and the psychological justification of inequality

The belief that status in society is based on merit is a central feature of the American Dream. This belief system justifies status inequalities by locating the cause of status differences in the individual talents and efforts of group members. We hypothesized that activating meritocratic beliefs increases the extent to which individuals psychologically justify status inequalities, even when those inequalities are disadvantageous to the self. Specifically, we hypothesized that priming meritocracy prompts individuals to engage in system-justifying psychological responses when they experience threat either at the personal or group level. Across two studies, priming meritocracy led members of a low status group to justify both personal and group disadvantage by decreasing perceptions of discrimination (Studies 1 and 2) and increasing the extent to which they stereotyped themselves and their group in status-justifying ways (Study 2).     

Decision-making in healthy children, adolescents and adults explained by the use of increasingly complex proportional reasoning rules

In the standard Iowa Gambling Task (IGT), participants have to choose repeatedly from four options. Each option is characterized by a constant gain, and by the frequency and amount of a probabilistic loss. Crone and van der Molen (2004) reported that school-aged children and even adolescents show marked deficits in IGT performance. In this study, we have re-analyzed the data with a multivariate normal mixture analysis to show that these developmental changes can be explained by a shift from unidimensional to multidimensional proportional reasoning (Siegler, 1981; Jansen & van der Maas, 2002). More specifically, the results show a gradual shift with increasing age from (a) guessing with a slight tendency to consider frequency of loss to (b) focusing on frequency of loss, to (c) considering both frequency and amount of probabilistic loss. In the latter case, participants only considered options with low-frequency loss and then chose the option with the lowest amount of loss. Performance improved in a reversed task, in which punishment was placed up front and gain was delivered unexpectedly. In this reversed task, young children are guessing with already a slight tendency to consider both the frequency and amount of gain; this strategy becomes more pronounced with age. We argue that these findings have important implications for the interpretation of IGT performance, as well as for methods to analyze this performance.     

Examining the Psychometric Properties of the Family Accommodation Scale-Parent-Report (FAS-PR)

Growing research has examined parental accommodation among the families of children with obsessive-compulsive disorder (OCD). However, these studies have utilized a parent-report (PR) version of a measure, the Family Accommodation Scale (FAS) that has never received proper psychometric validation. In turn, previously derived subscales have been developed via clinical rather than empirical evidence. This study aims to conduct a comprehensive psychometric analysis of the FAS-PR utilizing data collected from 96 youths with OCD. Exploratory factors analysis was conducted and revealed a 12-item scale yielding two separate, yet related subscales, Avoidance of Triggers (AT) and Involvement in Compulsions (IC). Subsequent analyses revealed good internal consistency and convergent and discriminant validity. These findings suggest that future research should seek to examine factors that may impact various facets to accommodation as well as the role these facets plays in predicting treatment outcome. Limitations are discussed.     

Processing of order information for numbers and months

Despite a great deal of research on the processing of numerical magnitude (e.g., the quantity denoted by the number 5), few studies have investigated how this magnitude information relates to the ordinal properties of numbers (e.g., the fact that 5 is the fifth integer). In the present study, we investigated order-related processing of numbers, as well as months of the year, with a novel ordering task to see whether the processing of order information differs from the processing of magnitude information. In Experiments 1 and 2, participants were shown three numbers (Experiment 1) or three months (Experiment 2) and were required to indicate whether the stimuli were in the correct order. In Experiment 3, participants were again shown three numbers; however, now they were instructed to indicate whether the three numbers were ordered in a forward, backward, or mixed direction. Whereas number comparison tasks typically reveal distance effects (comparisons become easier with increased distance between two numbers), these three experiments reveal a different pattern of results. There were reverse distance effects when the stimuli crossed a boundary (i.e., when numbers crossed a decade or months crossed the year boundary) and no effect of distance when the stimuli did not cross a boundary (i.e., when numbers were within a decade and months were within the January—December calendar year). These data suggest that additional mechanisms are involved in the processing of order information: a scanning mechanism and a long-term memory checking mechanism.     

Meno's Paradox,the Slave‐Boy Interrogation,and the Unity of Platonic Recollection

Plato invokes the Theory of Recollection to explain both ordinary and philosophical learning. In a new reading of Meno's Paradox and the Slave‐Boy Interrogation, I explain why these two levels are linked in a single theory of learning. Since, for Plato, philosophical inquiry starts in ordinary discourse, the possibility of success in inquiry is tied to the character of the ordinary comprehension we bring to it. Through the claim that all learning is recollection, Plato traces the knowledge achievable through inquiry back to our pretheoretical comprehension, showing not just that knowledge is in us, but that it is inchoate in the grasp of a property—akin to a concept—that enables us to speak and think about it ordinarily. Plato acknowledges in the Meno that a second step of argument, and a second application of Recollection, is needed to explain how knowledge comes to be inchoate in our ordinary grasp of a property. Though this second argument is provided most fully in the Phaedo, the evidence of the Meno is sufficient to outline Recollection as a two‐stage theory of learning, beginning in ordinary speech and thought and extending, through philosophical reflection, to knowledge.     

A dual-process account of female facial attractiveness preferences: Sexual and nonsexual routes

The current study conceptualizes facial attractiveness as a dual-process judgment, combining sexual and aesthetic value. We hypothesized that holistic face processing is more integral to perceiving aesthetic preference and feature-based processing is more integral to sexual preference. In order to manipulate holistic versus feature-based processing, we used a variation of the composite face paradigm. Previous work indicates that slightly shifting the top from the bottom half of a face disrupts holistic processing and enhances feature-based processing. In the present study, while nonsexual judgments best explained facial attraction in whole-face images, a reversal occurred for split-face images such that sexual judgments best explained facial attraction, but only for mate-relevant faces (i.e., other-sex). These findings indicate that disrupting holistic processing can decouple sexual from nonsexual judgments of facial attraction, thereby establishing the presence of a dual-process.     

Re-conceptualizing the Factor Structure of the Brief Multidimensional Measure of Religiousness/Spirituality

Rationale This study attempted to differentiate statistically the spiritual and religious factors of the Brief Multidimensional Measure of Religiousness/Spirituality (BMMRS), which was developed based on theoretical conceptualizations that have yet to be adequately empirically validated in a population with significant health disorders. Participants One hundred sixty-four individuals with heterogeneous medical conditions [i.e., brain injury, spinal cord injury (SCI), cancer, stroke, primary care conditions]. Methods Participants completed the BMMRS as part of a pilot study on spirituality, religion, and physical and mental health. Results A principal components factor analysis with varimax rotation and Kaiser normalization identified a six-factor solution (opposed to the expected 8-factor solution) accounting for 60% of the variance in scores, labeled as: (1) Positive Spiritual Experience; (2) Negative Spiritual Experience; (3) Forgiveness; (4) Religious Practices; (5) Positive Congregational Support; and (6) Negative Congregational Support. Conclusions The results suggest the BMMRS assesses distinct positive and negative aspects of religiousness and spirituality that may be best conceptualized in a psychoneuroimmunological context as measuring: (a) Spiritual Experiences (i.e., emotional experience of feeling connected with a higher power/the universe); (b) Religious Practices (i.e., prayer, rituals, service attendance); (c) Congregational Support; and (d) Forgiveness (i.e., a specific coping strategy that can be conceptualized as religious or non-religious in context).     

Neurophysiological evidence for categorical perception of color

The aim of this investigation was to examine the time course and the relative contributions of perceptual and post-perceptual processes to categorical perception (CP) of color. A visual oddball task was used with standard and deviant stimuli from same (within-category) or different (between-category) categories, with chromatic separations for within- and between-category stimuli equated in Munsell Hue. CP was found on a behavioral version of the task, with faster RTs and greater accuracy for between- compared to within-category stimuli. On a neurophysiological version of the task, event-related potentials (ERPs) showed earlier latencies for P1 and N1 components at posterior locations to between- relative to within-category deviants, providing novel evidence for early perceptual processes on color CP. Enhanced P2 and P3 waves were also found for between- compared to within-category stimuli, indicating a role for later post-perceptual processes.
