Imagination, language, and the perceptual world: a post-analytic phenomenology

This paper seeks to integrate analytic philosophy and phenomenology. It does so through an approach generated, specifically, in relation to imagination and its cognitive significance. As an Introduction, some reservations about existing phenomenological approaches to imagination—in the work of Sartre and Edward S. Casey—are considered. It is argued that their introspective psychological approach needs to be qualified through a more analytic orientation that determines essence, initially, on the basis of public discourse concerning the term ‘imagination.’ Part One then articulates this orientation through an ‘analytic reduction’ that identifies imagination’s essence in public discourse as thought in its quasi-sensory mode. Part Two offers a sustained phenomenological investigation of this essence, and identifies four major intrinsic features. On the basis of this, Part Three shows how imagination is implicated, centrally, in the capacity to acquire language. In Conclusion the proceeding arguments are defended against possible objections, and a final key summarizing argument is formulated to show that imagination must be regarded, also, as necessary to perception and its capacity to articulate a world. The paper ends with a few thoughts on the further potential of post-analytic phenomenology.     

Inhibition of return can be associated with object identity but not with object category

In this study, pre-schoolers and a comparison sample of fifth graders and high school students were presented with prediction tasks that varied by content of the base rate information (perceptual vs semantic) either presented alone (simple task) or accompanied by individuating data (complex task). Base rate choices, confidence scores, and explanations of the choices were registered. It is assumed that the presence of content effects in the processing of the base rates is in favour of a mental model account. Results indicated that pre-schoolers are able to build one-dimensional models with perceptual base rates in simple tasks. Fifth graders and high school students are able to build one-dimensional models with both types of content in simple tasks, as well as two-dimensional models in complex tasks. There is a local facilitation effect of semantic contents for fifth graders that disappears for high-school students. Consistency between subjects' choices, confidence scores and rationales depends on the subjects' grade, the number of sources involved, and the base rate content. Developmental trends are discussed in the light of previous research within formal, heuristic, and mental model approaches.     

Reasons for the growth of traditional memory span across age

Three studies, covering together the age range from 3 to 16 years, show the relationships between age, short-term memory span, and language abilities. The growth of the traditional memory span in childhood is systematically related to a concomitant growth of language abilities as tested with CELF-3 Screening, two tests of word knowledge, a test of reception of grammar (TROG-2), and the British Picture Vocabulary Test (BPVS). Linear regression and ANCOVA analyses show that the growth of memory span is fully explained by the growth of language abilities in the three studies that covered different subsamples of children. In a confirmatory factor analysis a two-factor model fits the data well and shows that a “crystallised” language factor is strongly related to age, whereas a “fluid” short-term memory factor is unrelated to age. The two-factor model gives support to Baddeley's multicomponent model of working memory, and the current data suggest that the capacity of the phonological store is fully developed in children younger than 4 years old. The authors hold that chunking capacity, highly dependent on language abilities, is a major source of memory span growth with age. Rather than an increase in the number of chunks, or episodes retained in short-term memory (=chunk span), it is argued that childhood memory span development reflects an increase in the size of each chunk (=chunking capacity).     

The amygdala but not the hippocampus is involved in pattern separation based on reward value

A total of 32 male Long-Evans rats were tested on a modified version of Flaherty, Turovsky, and Krauss's (1994) anticipatory contrast paradigm to assess pattern separation for reward value. Prior to testing, each rat received either a control, a hippocampal, or an amygdala lesion. In the home cage, each rat was allowed to drink a water solution containing 2% sucrose for 3 min followed by a water solution containing 32% sucrose for 3 min. Across 10 days of testing, the rats in each lesion group showed significantly increased anticipatory discriminability as a function of days. To assess the operation of a pattern separation mechanism, each rat was then tested using the same procedure except the 2% solution was followed by a 16% solution for 10 days and then by an 8% solution for 10 days. Control and hippocampal-lesioned rats continued to show high discriminability when the 2% solution was followed by a 16% solution; however, the amygdala-lesioned rats showed low anticipatory discriminability. On trials where the 2% sucrose solution was followed by an 8% sucrose solution, all groups showed low discriminability scores, suggesting that when two reward values are very similar even control animals are not able to separate the reward values in memory. However, the results of a preference task revealed that all groups can perceptually discriminate between a 2% and an 8% sucrose solution. The data suggest that the amygdala but not the hippocampus is involved in the separation of patterns based on reward value.     

Attempting to model dissociations of memory

Kinder and Shanks report simulations aimed at describing a single-system model of the dissociation between declarative and non-declarative memory. This model attempts to capture both Artificial Grammar Learning (AGL) and recognition memory with a single underlying representation. However, the model fails to reflect an essential feature of recognition memory - that it occurs after a single exposure - and the simulations may instead describe a potentially interesting property of over-training non-declarative memory.     

Development Through Work and Play

Adopting a work-play framework that attends to the adaptive, self-enhancing potential of play in work and human development contributes to an enhanced conceptualization of careers, both within career theory generally and the developmental perspective on careers specifically. Such a framework also promotes investigations of the connections between these life domains. Five proposals are made to imbue the developmental perspective on careers with a work-play fusion. These proposals examine how a work-play integration in vocational development theory, research, and counseling practice can foster optimal human development and therein aim to advance a revitalized developmental paradigm of career. Ultimately, theory construction and research inquiry that comprehends and investigates an integration of life roles in the domains of work and play could foster adaptability in human life-span development.     

The Twisted Relationship Between School Spending and Academic Outputs: in Search of a New Metaphor

In this commentary we explore both putative and potential relationships between school funding and educational outcomes, for which numerous indices and variables have been examined during the past two decades. We conclude that despite large increases in real dollars, there is no readily discernable link between inputs and outputs, although when statistical control is exerted over prior ability, school mix, and teacher turn-over, certain causal inferences appear warranted. However, it can be argued that the dominant analogy should be reconsidered, and schools serving large numbers of needy children may require higher inputs to keep from further declines, much like certain departments of a hospital require disproportionately more resources than others in order to be successful because they deal with problems that are more severe.     

Review of Jesus

This new psychobiographical analysis of Jesus by Donald Capps promises to be a controversial but important book. While the venture is an engaging one, new theses about what and why Jesus did what he did suffer the same sorts of challenges as have traditional and critical presentations of the historical Jesus. This review engages theological issues and their implications, historical judgments and their plausibility, and methodological approaches and their fruitfulness.
