Concept empiricism, content, and compositionality

Concepts are the constituents of thoughts. Therefore, concepts are vital to any theory of cognition. However, despite their widely accepted importance, there is little consensus about the nature and origin of concepts. Thanks to the work of Lawrence Barsalou, Jesse Prinz and others concept empiricism has been gaining momentum within the philosophy and psychology literature. Concept empiricism maintains that all concepts are copies, or combinations of copies, of perceptual representations—that is, all concepts are couched in the codes of perceptual representation systems. It is widely agreed that any satisfactory theory of concepts must account for how concepts semantically compose (the compositionality requirement) and explain how their intentional content is determined (the content determination requirement). In this paper, I argue that concept empiricism has serious problems satisfying these two requirements. Therefore, although stored perceptual representations may facilitate some traditionally conceptual tasks, concepts should not be identified with copies of perceptual representations.     

Using PPT to Analyze Suboptimal Human–Automation Performance

Diagnostic automation aids are designed to improve human performance by increasing accuracy in event detection tasks. However, human–automation performance has frequently fallen short of expectations, particularly when the aid is highly reliable. In those cases, human–automation performance is often suboptimal, in that a human being augmented with a diagnostic aid does more poorly than the automation itself. Previously, there have been only ambiguous explanations for why this occurs, with few suggestions on how to effectively eliminate suboptimal performance. Fortunately, with the advent of a new general theory of task performance, termed Potential Performance Theory (PPT) by D. Trafimow and S. Rice (2008 Trafimow, D. and Rice, S. 2008. Potential Performance Theory: A general theory of task performance applied to morality. Psychological Review, 115(2): 447–462. [Crossref], [PubMed], [Web of Science ®] , [Google Scholar]; 2009), one can now determine exactly why suboptimal performance occurs. Results from the present study reveal that inconsistency is the culprit, rather than just poor strategy selection. Furthermore, PPT allows one to determine exactly how much of the performance decrement is because of inconsistency.     

A Direct Method of Assessing Underlying Cognitive Risk for Adolescent Depression

An enduring tendency towards negative thinking is thought to increase vulnerability for future depression. However, it has not been possible to assess this tendency in non-depressed mood states. We examined if response latency to endorse dysfunctional attitudes is associated with depressive outcomes in a longitudinal study. A sample of young people at familial risk of depression (N?=?252, aged 10–19, 56.3 % female) completed a computer-administered dysfunctional attitude scale. The main outcome measure was the difference in reaction time to agree versus disagree with dysfunctional attitudes. Cross-sectional differences between current and previous depression and no psychiatric disorder groups as well as longitudinal associations with depressive symptoms were examined. Young people with current and previous depression were quicker to agree with dysfunctional attitudes than those without disorder. In young people free from depressive disorder, faster agreements with dysfunctional attitudes were specifically associated with increased depressive symptoms over time. Self-reported dysfunctional attitudes did not differentiate the formerly depressed and no disorder groups and showed a longitudinal association with depressive symptoms for older adolescents only. Reaction time to endorse dysfunctional attitudes may indicate changes in affective processing that represent an early risk for future depression that is not indexed by self-report measures of negative thought.     

The social class worldviews of first-generation college students

The social class worldviews (social class beliefs, attitudes, and values) of 14 first-generation college students were investigated with qualitative interviews. Consensual qualitative research analysis revealed first-generation students’ perspectives on the development of their social class worldviews, the effect of these worldviews on their transitions to college, and vice versa. The students’ pre-college beliefs and values promoted hard work and college attendance as a means of financial success. The transition to college created disequilibrium in the social class worldviews of the students interviewed, who in turn responded by attempting to adapt to the new culture, emphasizing their social class background, or downplaying the role of social class in their lives altogether. College professionals working with first-generation students are encouraged to facilitate dialogues with first-generation students about their social class worldview and its impact on students’ engagement with the college community.     

HENRY NELSON WIEMAN ON RELIGION AND REINHOLD NIEBUHR

Henry Nelson Wieman and Reinhold Niebuhr were theologically poles apart—Wieman a “new naturalist” and Niebuhr a “new super naturalist”—according to Wieman's nomenclature. Wieman devoted more time and attention to Niebuhr than Niebuhr did to him. The reason for this was the result of Wieman's sustained attack on the “new supernaturalism” with which he identified Niebuhr as one of the major American representatives. This article traces the background to Wieman's view of Niebuhr—Wieman's own views on science, on religion, and on Christianity—then proceeds to Wieman's analysis of Niebuhr's theology and his relation to the “new supernaturalism,” concluding with Niebuhr's reply to Wieman.     

Psychometric Properties and Administration Measurement Invariance of Social Phobia Symptom Measures: Paper-Pencil vs. Internet Administrations

The psychometric properties of the online versions of assessment instruments for phobias and related symptoms were compared to those of paper-pencil versions. The examined measures were the Social Interaction Anxiety Scale (SIAS) and Social Phobia Scale (SPS). Students (n = 514) completed the instruments either in a paper-pencil in lab condition or an online at home condition. Means of the measures were largely equivalent between the two groups. Factor structures of the measures support construct validity of the two versions of the questionnaires. The coefficient alphas for the measures were reasonably high, ranging between .91 and .93 for both groups. Correlations between the measures were similar across groups. Overall, adequate psychometric properties of the online versions of the instruments were demonstrated, however, neither of the social phobia measures demonstrated measurement invariance between the two assessment modalities.
