Reliance on Numerical Precision: Compatibility between Accuracy versus Efficiency Goals and Numerical Precision Level Influence Attribute Weighting in Two‐Stage Decisions

This research examines how the weighting of an attribute is jointly affected by attribute precision and decision stage. Building on prior work suggesting (a) that less (more) precise numerical values are easier to process (more accurate), (b) that decision‐makers' motivation to be efficient (accurate) is greater when creating a consideration set (making a final choice), and (c) that decision‐makers tend to overweight information that is compatible with their goals, we hypothesize that when creating a consideration set (making a choice) participants tend to assign greater weight to less (more) precise attributes. Five studies (two of them reported in the Appendix S1) offer triangulating evidence for these predictions. Overall, this work contributes to research on numerical cognition, efficiency versus accuracy trade‐offs, attribute weighting, and two‐stage decisions.     

Economic Poverty and Happiness in Rural Ecuador: the Importance of <Emphasis Type="Italic">Buen Vivir</Emphasis> (Living Well)

This research paper addresses the endemic dimensions of having or not having a good life using a concept of poverty based on self-reported subjective well-being. We build a subjective well-being poverty (SWBP) line and compare it with two income poverty (IP) lines. The endemic dimension comes from rural Ecuador and the indigenous happiness idea of Buen Vivir (Living Well), which has been the focus of growing attention in the scientific and the political arena. Discrepancies between SWBP and IP are deeply explored building models that explain SWBP with IP, as well as control variables and Buen Vivir related variables. We show that income poor households are more likely to be poor in terms of their reported subjective well-being. However, households that grow their own food and are in an indigenous community are less likely to report to be subjective well-being poor. The results suggest that low SWBP values in contrast with high IP may be explained by idiosyncratic components of the Buen Vivir philosophy. The components of the Buen Vivir ethos related to SWBP give rise to the idea of building multidimensional concepts of poverty based on what ethnic people consider to be good or bad for their specific way of life. In a general context, our study raises the importance of considering poverty and its dimensions taking into account the endemic factors of specific groups of people and cultures. That is, to take into account what is important for their lives.     

Executive Function and Theory of Mind in Children with ADHD: a Systematic Review

In developmental research, the relationship between Executive Function (EF) and Theory of Mind (ToM) has been extensively assessed, and EF has been considered a condition for ToM. However, few researchers have studied the relationship between EF and ToM in clinical populations, especially that of Attention Deficit Hyperactivity Disorder (ADHD), a neurodevelopmental disorder characterized by symptoms of inattention and motor hyperactivity/impulsivity, in which EF is largely impaired. Using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) model, 201 English and Spanish articles evaluating EF and ToM in ADHD were chosen. Fifteen papers met the inclusion criteria and were selected for further analysis. The first study dates from 2001. Most of the studies’ designs are cross-sectional, include mostly male children, have a small sample size, and were conducted in European countries. Unlike tasks assessing EF, tasks assessing ToM were heterogeneous across studies. The EFs most correlated with ToM were inhibitory control, working memory, cognitive flexibility, and attention. Interest in studying the relationship between EF and ToM in ADHD is recent,but increasing based on new findings and tuning of ToM instruments. However, while an association between EF and ToM is indicated in ADHD, the degree of prediction and predictability of one over the other cannot yet be established because of the studies’ heterogeneity.     

Compensatory processing during rule-based category learning in older adults

Healthy older adults typically perform worse than younger adults at rule-based category learning, but better than patients with Alzheimer’s or Parkinson’s disease. To further investigate aging’s effect on rule-based category learning, we monitored event-related potentials (ERPs) while younger and neuropsychologically typical older adults performed a visual category-learning task with a rule-based category structure and trial-by-trial feedback. Using these procedures, we previously identified ERPs sensitive to categorization strategy and accuracy in young participants. In addition, previous studies have demonstrated the importance of neural processing in the prefrontal cortex and the medial temporal lobe for this task. In this study, older adults showed lower accuracy and longer response times than younger adults, but there were two distinct subgroups of older adults. One subgroup showed near-chance performance throughout the procedure, never categorizing accurately. The other subgroup reached asymptotic accuracy that was equivalent to that in younger adults, although they categorized more slowly. These two subgroups were further distinguished via ERPs. Consistent with the compensation theory of cognitive aging, older adults who successfully learned showed larger frontal ERPs when compared with younger adults. Recruitment of prefrontal resources may have improved performance while slowing response times. Additionally, correlations of feedback-locked P300 amplitudes with category-learning accuracy differentiated successful younger and older adults. Overall, the results suggest that the ability to adapt one’s behavior in response to feedback during learning varies across older individuals, and that the failure of some to adapt their behavior may reflect inadequate engagement of prefrontal cortex.     

Predictors of psychological outcomes in a longitudinal study of Latina breast cancer survivors

Objective: This study sought to investigate the unique contributions of socio-ecological, cultural and cancer treatment-related factors in predicting depressive symptoms and cancer-specific distress among Latinas. Design: Participants were 140 English or Spanish-speaking Latinas (M_age = 50.6) with non-metastatic breast cancer who were assessed within two years of diagnosis (Time 1) and three months later (Time 2).

Main Measures: Hierarchical regression analyses identified predictors of depressive symptoms and cancer-specific distress at Time 1 and 2.

Results: Most women scored above the clinical cut-offs for depressive symptoms and cancer-specific distress. After adjusting for socio-ecological factors, greater Latino enculturation, measured by Latino ethnic identity, was significantly associated with greater cancer-specific distress at Time 1 (β = .20, p < .05). A significant interaction (p < .01) revealed that among women high on Latino identity, lower English language use was associated with more cancer-specific distress than higher English language use. After adjusting for socio-ecological factors, greater satisfaction with surgical treatment predicted improved depressive symptoms and cancer-specific distress across time (β_s range from ?.31 to ?.18, p_s < .01).

Conclusions: Findings elucidate the complex relationship between culture and psychological outcomes in the breast cancer context and suggest that treatment satisfaction might be an important intervention target for Latinas.     

THE REBIRTH OF THE IDOLS: THE FREUDIAN UNCONSCIOUS AND THE NIETZSCHEAN UNCONSCIOUS3

The author explores how psychoanalysis mutates in its passing from the privacies of the session to the public spaces of academia, shifting away from enquiry into unfolding unconscious psychic processes guided by its method, and from the clinically based notions Freud and his diverse followers constructed, here called the ‘Freudian unconscious’. In postmodern intellectual contexts Freud's work fuels a ‘Nietzschean unconscious’, issuing from public lecterns in the protagonistic, self‐creating feats of a ‘psychoanalytic discourse’. The ideology of such mutation ishere traced from Nietzsche on to Heidegger and Kojave, and then to Lacan and Laplanche. It reflects the might of the ‘death of evidences’ and the Romantic penchant for the limit‐experience and the primacy accorded to the creative imagination. Discourse as revelation rests on a ‘paradox of the enunciation’ whereby the subject (author) of the statement is taken to be identical to the subject (matter) of the statement. Banishing the boundaries of illusion and evidence, and of self‐overcoming and insight, academic ‘psychoanalytic discourse’creates a ‘return of the idols’ in ‘theoretical’ narcissistic identification.     

Development of a computer program to simulate the predictions of the replaced elements model of Pavlovian conditioning

Despite of the apparent simplicity of Pavlovian conditioning, research on its mechanisms has caused considerable debate, such as the dispute about whether the associated stimuli are coded in an "elementistic"(a compound stimuli is equivalent to the sum of its components) or a "configural" (a compound stimuli is a unique exemplar) fashion. This controversy is evident in the abundant research on the contrasting predictions of elementistic and the configural models. Recently, some mixed solutions have been proposed, which, although they have the advantages of both approaches, are difficult to evaluate due to their complexity. This paper presents a computer program to conduct simulations of a mixed model ( replaced elements model or REM). Instructions and examples are provided to use the simulator for research and educational purposes.     

Inhibitory tagging in inhibition of return: Evidence from flanker interference with multiple distractor features

Fuentes, Vivas, and Humphreys (1999) proposed a distinction betweeninhibition of return (IOR) and inhibitory processing taking place at a location subject to IOR. This latter mechanism,inhibitory tagging (IT), would act at a late level of processing related to response selection. In the present study, we examined whether IT was applied only to the target-relevant properties of the stimuli (e.g., to its color) or whether it was applied to other features of the stimulus as well (e.g., to its shape). Both when the task was to respond to the target’s color (Experiment 1) as well as when it was to respond to the target’s shape (Experiment 2), there was evidence of IT (reversal of the typical flanker effect at the cued location, relative to the uncued location) only to task-relevant features of the target. These findings suggest that IT is a central process of control constrained by task demands and current goals.
