Implicit self-esteem: nature, measurement, and a new way forward

Gaining insight into the nature and consequences of people's global self-evaluations (i.e., their self-esteem) has been fraught with difficulty. Nearly 2 decades ago, researchers suggested that such difficulties might be addressed by the development of a new class of measures designed to uncover implicit self-esteem. In this article, we evaluate the construct validity of the 2 most common measures of implicit self-esteem, the Implicit Association Test (IAT) and Name-Letter Test (NLT). Our review indicates that the research literature has not provided strong or consistent support for the validity of either measure. We conclude that both tests are impoverished measures of self-esteem that are better understood as measures of either generalized implicit affect (IAT) or implicit egotism (NLT). However, we suggest that there surely are aspects of self-esteem that people are unwilling or unable to report and suggest a general approach that may allow researchers to tap these unspoken aspects of self-esteem.     

A framework for the transfer of proofs,lemmas and strategies from classical to non classical logics

There exist valuable methods for theorem proving in non classical logics based on translation from these logics into first-order classical logic (abbreviated henceforth FOL). The key notion in these approaches istranslation from aSource Logic (henceforth abbreviated SL) to aTarget Logic (henceforth abbreviated TL). These methods are concerned with the problem offinding a proof in TL by translating a formula in SL, but they do not address the very important problem ofpresenting proofs in SL via a backward translation. We propose a framework for presenting proofs in SL based on a partial backward translation of proofs obtained in a familiar TL: Order-Sorted Predicate Logic. The proposed backward translation transfers some formulasF _TL belonging to the proof in TL into formulasF _SL , such that the formulasF _SL either (a) belong to a corresponding deduction in SL (in the best case) or, (b) are semantically related in some precise way, to formulas in the corresponding deduction in SL (in the worst case). The formulasF _TL andF _SL can obviously be considered aslemmas of their respective proofs. Therefore the transfer of lemmas of TL gives at least a skeleton of the corresponding proof in SL. Since the formulas of a proof keep trace of the strategy used to obtain the proof, clearly the framework can also help in solving another fundamental and difficult problem:the transfer of strategies from classical to non classical logics. We show how to apply the proposed framework, at least to S5, S4(p), K, T, K4. Two conjectures are stated and we propose sufficient (and in general satisfactory) conditions in order to obtain formulas in the proof in SL. Two particular cases of the conjectures are proved to be theorems. Three examples are treated in full detail. The main lines of future research are given.     

On the joint effects of repetition and stimulus quality in lexical decision: looking to the past for a new way forward

Two experiments investigated the joint effects of stimulus quality and repetition in the context of lexical decision. Experiment 1 yielded an interaction between repetition and stimulus quality for words (but additive effects for nonwords) when the lag was short, replicating previous reports. Experiment 2, with a much longer lag than Experiment 1, yielded main effects of stimulus quality and repetition, but these factors no longer interact. The joint effects of stimulus quality and repetition for words as a function of lag can be understood in terms of two loci for repetition effects: one short-term and one long-term. The transient effect of repetition is on activation levels in the lexicons (and in which the input lexicon, but not beyond, is affected by stimulus quality), whereas the long-term effect is on the strength of two-way connections between lexical-lexical and lexical-semantic modules. These data and others, taken together with the account, provide a new way of thinking about a 30-year-old conundrum.

A neuronal model of vowel normalization and representation

A speculative neuronal model for vowel normalization and representation is offered. The neurophysiological basis for the premise is the "combination-sensitive" neuron recently documented in the auditory cortex of the mustached bat (N. Suga, W. E. O'Neill, K. Kujirai, and T. Manabe, 1983, Journal of Neurophysiology, 49, 1573-1627). These neurons are specialized to respond to either precise frequency, amplitude, or time differentials between specific harmonic components of the pulse-echo pair comprising the biosonar signal of the bat. Such multiple frequency comparisons lie at the heart of human vowel perception and categorization. A representative vowel normalization algorithm is used to illustrate the operational principles of the neuronal model in accomplishing both normalization and categorization in early infancy. The neurological precursors to a phonemic vocalic system is described based on the neurobiological events characterizing regressive neurogenesis.     

A forward looking decision rule for imprecise credences

Adam Elga (Philosophers’ Imprint, 10(5), 1–11, 2010) presents a diachronic puzzle to supporters of imprecise credences and argues that no acceptable decision rule for imprecise credences can deliver the intuitively correct result. Elga concludes that agents should not hold imprecise credences. In this paper, I argue for a two-part thesis. First, I show that Elga’s argument is incomplete: there is an acceptable decision rule that delivers the intuitive result. Next, I repair the argument by offering a more elaborate diachronic puzzle that is more difficult for imprecise Bayesians to avoid.     

A microcomputer system for controlling classical conditioning experiments

A microcomputer-based laboratory system for controlling stimulus presentations and data acquisition in classical conditioning experiments is described. The system comprises an Intel 386/486-based microcomputer and a commercially obtained low-cost counter/timer board with input/output lines for stimulus timing and external device control. A simple, yet versatile custom-designed structured programming language is provided for performing an unlimited number of stimulus configurations and their sequences. In electrophysiological studies, the system can be flexibly connected to computer-controlled signal conditioning systems for the amplification and filtering of multiunit and evoked field potential responses and to high-speed data acquisition systems for sampling and analyzing the responses. The costs of reserving an entire microcomputer for experiment control are well compensated for by the simplicity and efficiency of programming and transportability of the control protocols between different setups and laboratories. Furthermore, a data acquisition and analysis system most suitable for the aims of a research project can be selected.     

A comparison of the effects of vicariously instigated classical conditioning and direct classical conditioning procedures

Two groups of Ss received either two or 16 paired classical conditioning trials beyond the peak CR. A third group received the same stimuli as in the 16 postpeak condition but in an unpaired and random order. The stimuli in all three groups were delivered directly to S. Subsequently, all three groups, including a fourth which was not given any prior direct classical conditioning, were exposed to vicariously instigated classical conditioning. This consisted of havingS observe someone (model) employed byE who received the same CS as was delivered during direct conditioning. The CS was paired with the feigned arm movement of the model, simulating a reaction to shock. This vicarious classical conditioning procedure when compared to direct classical conditioning resulted in smaller GSR magnitudes for both the CRs and UCRs. Previous experience with direct classical conditioning seems to have had an attenuating effect on GSR magnitude during the vicarious situation. A postexperimental questionnaire tended to support the results, and the relationship between the present study and current classical conditioning theory is discussed.     

A compensation for field expansion caused by moving forward

A way out of the wasteland

This essay describes the author's experiences with Judaism, with the art of Jane Austen, and with the thought of a radical Catholic theologian, Leslie Dewart. The author's synthesis of these disparate elements indicates that it is possible to achieve a religious view that satisfies one's spiritual and emotional needs without conflicting with the widespread modern conception of the integrity and openness of man's evolution.     

A minicomputer program for control and data acquisition in classical conditioning

A 4K PDP-8/E computer program package has been developed to control classical conditioning procedures, to collect response data, and to extract statistical summeries. In contrast with other existing behavioral control languages geared to digital data typical of discrete operant analyses, this program distinguishes itself by its ability to retrieve and analyze the analog data arising from phasic response systems such as the rabbit’s nictitating membrane. By means of a question-and-answer Teletype conversation with the E, the program establishes trial sequence and trial spacing parameters; CS and US duration, probability, and interstimulus interval; intertrial interval fractionation for recording intertrial response frequencies; and session length. Various versions of the program exist to compute statistical properties of the analog response data, to dump detailed trial-by-trial topographies, and to attach instrumental contingencies to subtle features of the real-time analog responding.     

A comparison of forward and backward procedures for the acquisition of response chains in humans

Ten university students each learned four separate six-link response chains, two forward and two backward. All 10 subjects made fewer errors in the forward procedure. It was concluded that the forward procedure is superior because each link of the response chain is acquired by direct reinforcement.     

Constraints on the processes responsible for the extrinsic normalization of vowels

Listeners tune in to talkers’ vowels through extrinsic normalization. We asked here whether this process could be based on compensation for the long-term average spectrum (LTAS) of preceding sounds and whether the mechanisms responsible for normalization are indifferent to the nature of those sounds. If so, normalization should apply to nonspeech stimuli. Previous findings were replicated with first-formant (F1) manipulations of speech. Targets on a [pt]–[p?t] (low–high F1) continuum were labeled as [pt] more after high-F1 than after low-F1 precursors. Spectrally rotated nonspeech versions of these materials produced similar normalization. None occurred, however, with nonspeech stimuli that were less speechlike, even though precursor–target LTAS relations were equivalent to those used earlier. Additional experiments investigated the roles of pitch movement, amplitude variation, formant location, and the stimuli's perceived similarity to speech. It appears that normalization is not restricted to speech but that the nature of the preceding sounds does matter. Extrinsic normalization of vowels is due, at least in part, to an auditory process that may require familiarity with the spectrotemporal characteristics of speech.     

Lexical access and the spelling-to-sound regularity effect

A number of investigators have reported that words that follow spelling-to-sound rules can be recognized faster than words that violate such rules (the “regularity” effect). On occasion, the absence of a regularity effect is reported, however. The first two experiments of the present paper report that a regularity effect can be obtained in a lexical decision task with word sets that previously have been reported not to produce such an effect, when consideration is given to the consistency or inconsistency of the pronunciations of each word’s visually similar ‘neighbors” Subsequent experiments demonstrated that the obtained regularity effect does not vary as a function of mixed- vs. single-case presentation (Experiment 3) or visual quality (Experiment 4) in a lexical decision task. These results are explained in terms of Glushko’s (1979) activation and synthesis model of lexical access. It is argued that the obtained results are incompatible with traditional dual process models of lexical access (which incorporate separate visual and phonological pathways and spelling-to-sound rules) and fully compatible with Glushko’s model. It is concluded that spelling-to-sound regularity is not a property of a word in isolation, but rather a property of a word in the context of visually similar words that are activated in the course of recognition.     

A reappraisal of classical archetype theory and its implications for theory and practice

Abstract: This paper begins with an overview of contemporary approaches to archetype theory and notes the radical nature of certain deductions. Some argue that there is no ‘archetype‐as‐such’ as a pre‐existing entity at the core of a complex driving its formation whilst the findings of current neuroscience are calling into question one very thing on which the classical theory is built – innatism. Knox's argument for image schemas raises the question as to the extent to which archetypes can be conceived in any preformationist sense. The question is then posed – to what extent can Jung's classical theory of archetypes be read in light of these current models? The case examples Jung uses to evidence the existence of archetypes, his explications of synchronicity and his own Philemon experience are then reappraised. The conclusion is drawn that it is difficult to evidence the existence of autonomous archetypes unrelated to personal affective experience. Not only would this be expected by emergent/developmental models of archetype but it can explain many of Jung's disjunctive statements about archetype constellation; the difficulties in separating personal and collective psychic content and Jung's apparent Lamarckianism. The implications of these models for theory, clinical practice and analyst training are then offered for discussion.
