“I can see it in your eyes”: Biased Processing and Increased Arousal in Dishonest Responses

According to self‐maintenance theory, people notice their dishonest acts and thus experience ethical dissonance between their misconduct and their positive moral self. In this view, dishonesty is facilitated by justifications that redefine moral boundaries. By contrast, the bounded ethicality approach suggests that biased perception prevents people from becoming aware of their dishonesty. We tested the key process assumptions behind these accounts using pupillary responses and fixation data and found physiological evidence for both kinds of mechanisms. In particular, physiological arousal increased at the initial stage of cheating responses. This suggests that people are on some level aware of their wrongdoings. At the same time, however, we found attentional biases that can reduce the likelihood for detecting potentially disadvantageous information. We suggest that dishonest acts come at the internal cost of increased tension, which people aim to avoid by pre‐emptive biased processing as well as post hoc justifications.

MECHANISMS OF PLACEBO PAIN REDUCTION:

Abstract— Identical experimental pain stimuli were applied to the right and left index fingers of 56 university students, following the application of a placebo in the guise of a topical anesthetic to one of the fingers. The pain stimuli were administered simultaneously to treated and untreated fingers for half of the subjects and sequentially for the others Significant and equtvalent reductions in pain were reported in both conditions as a function of placebo administration. These data indicate that reductions of experimental pain produced by placebos presented in the guise of local anesthetics are not mediated by such global mechanisms as anxiety reduction or the release of endogenous opioids.     

A pragmatic account of a presuppositional effect

Two different theoretical accounts of a presuppositional effect in sentence interpretation were considered. One is a semantic account based on componential analysis. The other is a pragmatic account based on relevance theory which does not call for lexical decomposition. The two theoretical points of view were tested against each other by making use of a well-known riddle, studied by Noordman (1979), whose standard form is: “You are my son, but I am not your father. Who am I?” In the first experiment, a manipulation based on the replacement of a lexical unit with a paraphrastic expression that did not contain the critical semantic component failed to enhance performance, whereas in the second experiment, a manipulation of contextual information leaving the lexical unit unaltered was successful in modifying performance. Both results conform to the predictions of relevance theory, but are at variance with the predictions of the componential theory.

The effects of computer-mediated vocational guidance procedures on the appropriateness of vocational preference

To assess the effectiveness of vocational guidance procedures proposed for inclusion in a computer-based vocational exploration system, 139 eleventh-grade male subjects were randomly assigned to three experimental groups and a control group. One group was given a computer-generated accuracy of self-knowledge feedback, another group was taught an occupational classification scheme, a third group experienced both. Utilizing a method of explicit comparison between students' measured characteristics and the measured characteristics of occupational norm groups, the results showed students in the groups receiving feedback increased in the appropriateness of the occupational level of their first occupational choice. In addition, students in the combined treatment group increased in the appropriateness of the level of their total occupational preferences. A delayed posttest indicated that these increases persisted.     

Agreement among teacher,peer, and self-ratings of children's aggression,withdrawal, and likability

This study examined the relationship among teacher, peer, and self-ratings of children's social behavior. The Pupil Evaluation Inventory was completed by 172 first-graders, 346 fourth-graders, 283 seventh-graders, and 30 teachers. Groups of deviant responders and controls were also selected from the total sample on the basis of peer-rated aggression and withdrawal scores. Interrater agreement was consistently greater between peer and teacher ratings than between self-ratings and either peer or teacher ratings. Discrepancies between raters were greatest for children with more deviant scores, with peer ratings providing the highest estimates of deviant behavior, and self ratings yielding the lowest. Self ratings were lower than teacher or peer ratings on aggression and withdrawal, and higher on likability. Aggression produced greatest agreement between raters. Agreement was uninfluenced by the cognitive maturity of peer evaluators. The results suggest that the selection of raters should be influenced by the class of behaviors to be evaluated and the context in which they occur.This research was funded by Québec Ministry of Social Affairs Grant RS 281 to Jane Ledingham and Alex Schwartzman.

Evidence for phonetic processing of cues to place of articulation: Perceived manner affects perceived place

Using stimuli that could be labeled either as stops [b,d] or as fricatives [f,v,θ,ð], we found that, for a given acoustic stimulus, perceived place of articulation was dependent on perceived manner. This effect appeared for modified natural syllables with a free-identification task and for a synthetic transition continuum with a forced-choice identification task. Since perceived place could be changed by changing manner labels with no change in the acoustic stimulus, it follows that the processing of the place feature depends on the value the listener assigns to the manner feature rather than directly on any of the acoustic cues to manner. We interpret these results as evidence that the identification of place of articulation involves phonetic processing and could not be purely auditor     

Distraction and time estimation

It is argued that events which occur during an interval of time which is being judged may be classified in terms of their effects on the alertness of the subject, and in terms of the degree to which they distract him from the task of detecting and processing time-relevant cues. A distracting task, defined by the number of arithmetical operations a subject was required to perform, was presented while reproductions of an interval were being made. The data support the prediction that the higher the level of distraction, the less time a subject will judge to have elapsed during an objective period.     

Enhanced Hippocampal CA1 LTP but Normal Spatial Learning in Inositol 1,4,5-trisphosphate 3-kinase(A)-Deficient Mice

To define the physiological role of IP₃3-kinase(A) in vivo, we have generated a mouse strain with a null mutation of the IP₃3-kinase(A) locus by gene targeting. Homozygous mutant mice were fully viable, fertile, apparently normal, and did not show any morphological anomaly in brain sections. In the mutant brain, the IP₄ level was significantly decreased whereas the IP₃ level did not change, demonstrating a major role of IP₃3-kinase(A) in the generation of IP₄. Nevertheless, no significant difference was detected in the hippocampal neuronal cells of the wild-type and the mutant mice in the kinetics of Ca²⁺ regulation after glutamate stimulation. Electrophysiological analyses carried out in hippocampal slices showed that the mutation significantly enhanced the LTP in the hippocampal CA1 region, but had no effect on the LTP in dentate gyrus (DG). No difference was noted, however, between the mutant and the wild-type mice in the Morris water maze task. Our results indicate that IP₃3-kinase(A) may play an important role in the regulation of LTP in hippocampal CA1 region through the generation of IP₄, but the enhanced LTP in the hippocampal CA1 does not affect spatial learning and memory.     

What Lies Outside Language?

The paper aims to make out the incoherence of the distinction between and rigid separation of 'the linguistic' and 'the extra-linguistic' as well as to absolve Wittgenstein from any commitment to it. Insistence on a descent from the abstract to a concrete discussion allows a connection to be made between Tractatus positions such as: 'The limits of my language indicate the limits of my world.' and 'The world and life are one.' and the Investigations : 'What has to be accepted is - so one could say - forms of life .' From this a picture is developed of the intimate interconnection between language, practical life, and world.
