Monogeusia for fructose,glucose, sucrose,and maltose

We investigated the ability of subjects to discriminate sugars with a whole-mouth forced-choice paradigm, in which a standard solution was compared with a test solution of varied concentration. Discrimination probabilities were U-shaped functions of test concentration: for 6 subjects and pairwise combinations of fructose, glucose, and sucrose, discriminability always declined to chance over a narrow range of test concentrations. At concentrations ≦ 100 mM, maltose was indiscriminable from fructose but discriminable at higher concentrations for 4 subjects. By analogy with themonochromacy of night vision, whereby any two lights are indiscriminable when their relative intensities are suitably adjusted, we call the gustatory indiscriminability of these sugarsmonogeusia. The simplest account of monogeusia is that all information about the indiscriminable sugars is represented by a single neural signal that varies only in magnitude. The discriminability of maltose from the other sugars at higher concentrations is consistent with the hypothesis that maltose also activates a second gustatory code.     

Coalition Preference as a Function of Expected Values in a Tetradic Weighted-Majority Game

Eighty male subjects participated in a tetradic weighted-majority game in which a coalition was required to control the division of the payoff. The amount of the payoff and/of the probability of receiving the payoff were varied. The data strongly supported the hypothesis that subjects would prefer the coalition with the largest expected value (size of payoff x probability of success = expected value) rather than the coalition with the largest payoff or the coalition with the highest probability of success. However, contrary to expectations, the 'division of rewards was found to be a function of the relative assigned resources of the coalition members, despite the lack of a logical connection between the assigned resources and the rules governing obtaining the payoff.     

A Comparison of Modalities in Modeling

Organizational display rules (e.g., “service with a smile”) have had mixed relationships with employee emotional labor—either in the form of “bad faith” surface acting (suppressing or faking expressions) or “good faith” deep acting (modifying inner feelings). We draw on the motivational perspective of emotional labor to argue that individual differences in customer orientation will directly and indirectly relate to these acting strategies in response to display rules. With a survey of more than 500 working adults in customer contact positions, and controlling for affective disposition, we find that customer orientation directly increases “good faith” acting while it moderates the relationship of display rules with “bad faith” acting.     

THE SECOND SPHERE AND THE STORY OF NO STORY

The author discusses Roy Schafer's ideas of the second self and second reality, as well as his consistent theme of storyteller and story. The latter theme is also explored in the context of more recent psychoanalytic influences, such as Bionian thought, trauma theory, the French approach, and the interpersonal perspective. To illustrate the idea of the nonstory in today's clinical encounters, the author presents two clinical vignettes.     

The protective effects of ethnic identity for alcohol and marijuana use among Black young adults

This study examined the extent to which individual differences in alcohol and marijuana use among 167 Black university students could be accounted for by degree of ethnic identity. After controlling for year in school, sex, and friends' substance use, higher levels of ethnic identity indeed were found to be significantly related to lower beer/hard liquor use, wine use, and marijuana use, accounting for approximately 31%, 6%, and 4% of the variance, respectively. For marijuana use, however, friends' substance use accounted for more of the variance (13%) than did ethnic identity (4%).     

Counselor Competency in the Courtroom

This article outlines general courtroom procedures and offers systematic practical advice for the counselor testifying as an expert witness. Major topics include the counselor role in court, preparing for testimony, answering questions, and dealing with the cross-examination.     

Resolving boundary problems among therapists

When several psychotherapists work with the same client, the various domains and responsibilities of the therapists can be so unclear and confusing as to hinder the therapeutic process. The author presents a case example of a woman who was involved with 13 theraplsts of varying educational and theoretical backgrounds. Although the confusion and power struggles that occurred within this multiple-therapist system were eventually resolved, the situation caused the patient unnecessary distress. Suggestions related to clarifying therapeutic system boundaries and defining and ordering therapeutic power hierarchies are presented with the intent of facilitating more functional therapeutic systems.Special thanks to Christy Wright, David B.
