Costs and benefits of representational change: effects of context on age and sex differences in symbolic magnitude estimation

Studies have reported high correlations in accuracy across estimation contexts, robust transfer of estimation training to novel numerical contexts, and adults drawing mistaken analogies between numerical and fractional values. We hypothesized that these disparate findings may reflect the benefits and costs of learning linear representations of numerical magnitude. Specifically, children learn that their default logarithmic representations are inappropriate for many numerical tasks, leading them to adopt more appropriate linear representations despite linear representations being inappropriate for estimating fractional magnitude. In Experiment 1, this hypothesis accurately predicted a developmental shift from logarithmic to linear estimates of numerical magnitude and a negative correlation between accuracy of numerical and fractional magnitude estimates (r = −.80). In Experiment 2, training that improved numerical estimates also led to poorer fractional magnitude estimates. Finally, both before and after training that eliminated age differences in estimation accuracy, complementary sex differences were observed across the two estimation contexts.     

Apprentissage de concepts perceptuels, associationnels et relationnels chez le pigeon

The study of concepts in cognitive psychology has generally been anthropocentric with respect to both content and theory. A broader comparative perspective on the various forms of concept learning would provide a more inclusive view of conceptual behavior. It would also provide a more objective perspective from which to identify underlying processes. Several of the major varieties of conceptual classes claimed for humans alone also appear to be represented in nonhuman animals and young children: perceptual classes involving classification according to the shared attributes of objects, associative classes or functional equivalences in which stimuli form a class based on common associations and relational classes, in which the conceptual relationship between stimuli defines the class.     

Qualitative differences in the representation of abstract versus concrete words: Evidence from the visual-world paradigm

In the present visual-world experiment, participants were presented with visual displays that included a target item that was a semantic associate of an abstract or a concrete word. This manipulation allowed us to test a basic prediction derived from the qualitatively different representational framework that supports the view of different organizational principles for concrete and abstract words in semantic memory. Our results confirm the assumption of a primary organizational principle based on association for abstract words, different from the semantic similarity principle proposed for concrete words, and provide the first piece of evidence in support of this view obtained from healthy participants. The results shed light on the representational structure of abstract and concrete concepts.     

Abstract concepts,compositionality, and the contextualism-invariantism debate

Invariantists argue that the notion of concept in psychology should be reserved for knowledge that is retrieved in a context-insensitive manner. Contextualists argue that concepts are to be understood in terms of context-sensitive ad hoc constructions. I review the central empirical evidence for and against both views and show that their conclusions are based on a common mischaracterization of both theories. When the difference between contextualism and invariantism is properly understood, it becomes apparent that the way the question of stability is currently investigated will not lead to a consensus. Instead of focusing directly on stability, we should turn our attention to other desiderata on a theory of concepts. In particular, I show that invariantism, but not contextualism, fails to account for compositionality and abstract concepts.     

Concept History and Religious Discourse

Since the second half of the twentieth century, the history of concepts (Begriffsgeschichte) has made important contributions to the study of political and social thought, as well as to cultural history more generally. Reinhart Koselleck has argued that, during the eighteenth century, basic concept use in Europe experienced widespread trends of (1) democratization, (2) temporalization, (3) ideologization, and (4) politicization. This article will consider the possibility of a conceptual history of religious discourse. While conceptual history has thus far focused primarily on political and social concepts, some research has more recently turned to religious concepts. This work should be expanded and can be improved by the insight of theologians and ethicists who often have a better understanding of religious concept use than conceptual historians whose main focus is political thought. I will summarize how concept history could be applied to religious concepts, how theologians might make a contribution to the theory behind Koselleck's understanding of modern concept use, and offer a critique of a recent methodological introduction to religious concept history.     

To infinity and beyond: Children generalize the successor function to all possible numbers years after learning to count

Recent accounts of number word learning posit that when children learn to accurately count sets (i.e., become “cardinal principle” or “CP” knowers), they have a conceptual insight about how the count list implements the successor function – i.e., that every natural number n has a successor defined as n + 1 (Carey, 2004, 2009; Sarnecka & Carey, 2008). However, recent studies suggest that knowledge of the successor function emerges sometime after children learn to accurately count, though it remains unknown when this occurs, and what causes this developmental transition. We tested knowledge of the successor function in 100 children aged 4 through 7 and asked how age and counting ability are related to: (1) children’s ability to infer the successors of all numbers in their count list and (2) knowledge that all numbers have a successor. We found that children do not acquire these two facets of the successor function until they are about 5½ or 6 years of age – roughly 2 years after they learn to accurately count sets and become CP-knowers. These findings show that acquisition of the successor function is highly protracted, providing the strongest evidence yet that it cannot drive the cardinal principle induction. We suggest that counting experience, as well as knowledge of recursive counting structures, may instead drive the learning of the successor function.     

Group affective learning in training for psychotherapy and psychoanalysis

This paper describes The Group Affective Model, a method for teaching psychoanalytic concepts and their clinical application, using multi‐channel teaching, process and review in group settings, and learning from experience in an open systems learning community for psychoanalysts and psychotherapists. This innovation arose in response to criticism of existing methods in psychoanalytic education that have subordinated the primary educational task to that of the training analysis. Noticing this split between education and training analysis, between cognition and affect, and between concepts of individual and group unconscious processes, we developed the Group Affective Model for teaching and learning psychoanalysis and psychotherapy in an open psychological space in which students and faculty experience individual and group processes of digestion, assimilation, and review, which demonstrate the concepts in action and make them available for internalization selectively. We discuss our philosophy and our educational stance. We describe our institution and our participants. We give examples of teaching situations that we have studied to provide some insight about assimilation and internalization of the concepts and clinical approaches being taught. We discuss the transferability of the Group Affective Model to other teaching settings and psychoanalytic training institutions and propose it as the fourth pillar of psychoanalytic training, next to analytic treatment, clinical supervision, and didactic seminars.

Spatial and linguistic aspects of visual imagery in sentence comprehension

There is mounting evidence that language comprehension involves the activation of mental imagery of the content of utterances ( Barsalou, 1999 ; Bergen, Chang, & Narayan, 2004 ; Bergen, Narayan, & Feldman, 2003 ; Narayan, Bergen, & Weinberg, 2004 ; Richardson, Spivey, McRae, & Barsalou, 2003 ; Stanfield & Zwaan, 2001 ; Zwaan, Stanfield, & Yaxley, 2002 ). This imagery can have motor or perceptual content. Three main questions about the process remain under‐explored, however. First, are lexical associations with perception or motion sufficient to yield mental simulation, or is the integration of lexical semantics into larger structures, like sentences, necessary? Second, what linguistic elements (e.g., verbs, nouns, etc.) trigger mental simulations? Third, how detailed are the visual simulations that are performed? A series of behavioral experiments address these questions, using a visual object categorization task to investigate whether up‐ or down‐related language selectively interferes with visual processing in the same part of the visual field (following Richardson et al., 2003 ). The results demonstrate that either subject nouns or main verbs can trigger visual imagery, but only when used in literal sentences about real space—metaphorical language does not yield significant effects—which implies that it is the comprehension of the sentence as a whole and not simply lexical associations that yields imagery effects. These studies also show that the evoked imagery contains detail as to the part of the visual field where the described scene would take place.     

The Space–Time Congruency Effect: A Meta‐Analysis

Several reaction time (RT) studies report faster responses when responses to temporal information are arranged in a spatially congruent manner than when this arrangement is incongruent. The resulting space–time congruency effect is commonly attributed to a culturally salient localization of temporal information along a mental timeline (e.g., a mental timeline that runs from left to right). The present study aims to provide a compilation of the published RT studies on this time–space association in order to estimate the size of its effect and the extent of potential publication bias in this field of research. In this meta‐analysis, three types of task are distinguished due to hitherto existing empirical findings. These findings suggest that the extent to which time is made relevant to the experimental task has a systematic impact on whether or not the mental timeline is activated. The results of this meta‐analysis corroborate these considerations: First, experiments that make time a task‐relevant dimension have a mean effect size of d = 0.46. Second, in experiments in which time is task irrelevant, the effect size does not significantly deviate from zero. Third, temporal priming studies have a surprisingly high mean effect size of d = 0.47, which, however, should be adjusted to d = 0.36 due to publication bias.
