The empirical base of Trope's position on achievement-task choice: A critique

The empirical base of Trope's position on achievement-task choice is critiqued here. Attention is focused on Trope's earliest studies (Trope, 1975; Trope & Brickman, 1975) because they provide this position's most critical tests. Support for the following three propositions of the position is assessed: (1) diagnosticity information, rather than task difficulty information, is the basis of task selection; (2) desire for information about one's ability, not the wish for certain affective consequences, is what motivates achievement-task choice; and (3) the success of the Atkinson model is owed to the adventitious confounding existing between task diagnosticity and task difficulty, and the resulting confounding between ability-informational and affective consequences. The major findings are that (1) the tests of all propositions have such serious logical flaws that they cannot answer the questions they seek to answer, (2) the task choice situation containing the diagnosticity manipulation employed by Trope is so different from real-life task choice situations as to call into question the relevance of Trope's findings for the latter situations, (3) Trope's diagnosticity manipulation is a meaningless one as it gives rise to situations that are logical impossibilities (e.g., skill tasks that are performed equally well by high- and low-skilled people), and (4) the tests of Atkinson's position are invalidated by a serious misinterpretation of that position by Trope.     

Update on the biology of seasonal affective disorder

The etiology and pathophysiology of seasonal affective disorder (SAD) has been linked to the seasons and to light since its first conceptualization. Aspects of SAD that make it particularly amenable to biological investigation include the predictable recurrent episodes, the rapid response to a nonpharmacologic treatment, the specific neurovegetative features, and the availability of rich animal models of seasonality. This paper reviews new findings for the major biological hypotheses for SAD, focusing on circadian rhythms, neurotransmitters, and molecular genetics. Integrative issues and future directions for the study of SAD, including the heuristic value of a dual-vulnerability hypothesis that conceptualizes seasonality as a dimensional construct and the importance of studying endophenotypes, will be discussed.     

An information-processing model of the BOLD response in symbol manipulation tasks

Two imaging experiments were performed—one involving an algebraic transformation task studied by Anderson, Reder, and Lebiere (1996) and the other an abstraction symbol manipulation task studied by Blessing and Anderson (1996). ACT-R models exist that predict the latency patterns in these tasks. These models require activity in an imaginal buffer to represent changes to the problem representation, in a retrieval buffer to hold information from declarative memory, and in a manual buffer to hold information about motor behavior. A general theory is described about how to map activity in these buffers onto the fMRI blood oxygen level dependent (BOLD) response. This theory claims that the BOLD response is integrated over the duration that a buffer is active and can be used to predict the observed BOLD function. Activity in the imaginal buffer is shown to predict the BOLD response in a left posterior parietal region; activity in the retrieval buffer is shown to predict the BOLD response in a left prefrontal region; and activity in the manual buffer is shown to predict activity in a motor region. More generally, this article shows how to map a large class of information-processing theories (not just ACT-R) onto the BOLD response and provides a precise interpretation of the cognitive significance of the BOLD response.     

Regulatory focus as a predictor of omission bias in moral judgment: Mediating role of anticipated regrets

Omission bias occurs when people are more reluctant to accept negative consequences caused by their actions than by their inaction. Recent research on omission bias in decision‐making has found evidence for individual differences, thus indicating that some people are more likely to show omission inclination than others. The present research aims to explore the role of regulatory focus as individual difference variables in omission bias. Moreover, we examine whether anticipated regret mediates the relationship between regulatory focus and moral judgement. Moral judgement tasks utilized include: (i) moral dilemma scenarios (Study 1); and (ii) ethical scenarios embracing apparent legal rule violations (Study 2). The results of both studies show that only prevention focus is significantly related to omission bias in moral judgement. Specifically, this relationship holds regardless of the nature of the ‘omission’ (whether they are deontological or utilitarian). In addition, anticipated regret/guilt for action was found to mediate the relationship between prevention focus and omission bias. Implications and limitations are discussed based on the results of the current study.     

Height and Happiness in a Developing Country

This paper analyzes the Indonesian Family Life Survey to estimate the relationship between height and happiness in a developing country, Indonesia. This paper finds that tall men and women are happier than their short counterparts and that the magnitude of the relationship is large. More important, a parsimonious set of channels is identified to substantially explain the relationship between height and happiness: education and earnings for men, and education and relative position of earnings for women. However, for men but not for women, height still exhibits a non-negligible relationship with happiness even after controlling for an extensive array of covariates.     

The effect of working memory capacity on conflict monitoring

The conflict adaptation effect, a reduced interference effect upon the detection of a conflict signal (e.g., following an incongruent trial), has been interpreted as evidence for active regulation of top-down cognitive control. We hypothesized that the extent of conflict adaptation should be related to individuals' working memory capacity (WMC), which has been repeatedly demonstrated to reflect the level of cognitive control. Using the Simon task, in Experiment 1, we quantified the conflict adaptation ratio (CAR) transiently as the ratio of the conflict effect following an incongruent trial to the conflict effect following a congruent trial, controlling for the reaction time that often correlates with WMC. We observed that the CAR varied from highly negative with low WMC scores to near-zero with high WMC scores. This result suggests that high WMC individuals, when detecting conflict, adjust the level of cognitive control optimally so that their performance is less susceptible to the presence of a distractor. In Experiment 2, we quantified the CAR in a sustained manner as the ratio of the conflict effect from predominantly incongruent blocks to the conflict effect from predominantly congruent blocks. Again, the CAR varied from negative to zero as WMC increased. These results suggest that WMC may reflect, in addition to the ability to maintain a level of control, the ability to adjust the level of control appropriately to the contextual demands.     

Emmanuel Levinas and the New Science of Judaism

This article addresses Emmanuel Levinas's re‐conceptualization of Jewish identity by examining his response to a question he himself poses: “In which sense do we need a Jewish science?” First, I attend to Levinas's critique of modern science of Judaism, particularly as it was understood in the critical approaches of the nineteenth‐century school of thought, Wissenschaft des Judentums. Next, I detail Levinas's own constructive proposal that would, in his words, “enlarge the science of Judaism.” He retrieved classical textual sources that modern Judaism had neglected, while at the same time he enlarged Judaism's relevance beyond a historical community by turning to phenomenology as a rigorous science. Finally, I conclude with some reflections on the broader implications of this new science of Judaism for Jewish ethics and identity in a post‐war period.     

Degree of extraversion and physiological responses to physical pain and sadness

Extraversion is a personality frequently discussed as one of the strongest and most consistent factors that relates to individual subjective wellbeing. The goal of this study was to better understand how people with varying degrees of extraversion psychologically and physiologically respond differently to unpleasant circumstances. Emotional responses (e.g., levels of intensity, valence, and arousal) were assessed in determining the sensitivity level to negative stimuli that were specifically designed to provoke physical pain and sadness emotion. Physiological changes (e.g., heart rate (HR), blood volume pulse (BVP), and respiratory sinus arrhythmia (RSA)) were also measured during pain and sadness to observe sympathetic and parasympathetic activities. Our results showed that the degree of extraversion was associated with less unpleasant responses to sadness, less HR responses to both pain and sadness, and greater RSA responses to sadness. The findings suggest that the lower HR reactivity to painful and sad situations and greater RSA reactivity to sad situations in extraversion could be possibly due to increased parasympathetic activity. Additionally, enhanced parasympathetic activity to negative situations may explain an important mechanism underlying the positive connection between extraversion and subjective wellbeing.     

The effect of self‐regulated decision making on career path and major‐related career choice satisfaction

The present research examined the influence of self‐regulated decision making on satisfaction in career path (college major for Study 1, job for Study 2) and major‐related career choice. Results indicate a full mediating effect of fit in the relationship between self‐regulated decision making and satisfaction in career path. Self‐regulated decision making also influenced major–job congruence via satisfaction with a participant's college major. Findings suggest that individuals who possess self‐regulatory ability in decision‐making contexts were more likely to choose majors and jobs of good fit, experience satisfaction from their career decisions, and choose careers relevant to their college majors.
