The Effect of Generalized Compliments,Sex of Server,and Size of Dining Party on Tipping Behavior in Restaurants1

This study examined the effects of food servers' sex, the use of generalized compliments, and the size of the dining party on tipping behavior in restaurants. Four food servers (2 males, 2 females) waited on 360 parties eating dinner, and either complimented or did not compliment the parties on their dinner selections. Results indicated that food servers received significantly higher tips when complimenting their parties than when not complimenting them, although as the size of the party increased, the effectiveness of compliments decreased. These results and their implications are discussed.     

A General Family of Limited Information Goodness-of-Fit Statistics for Multinomial Data

Maydeu-Olivares and Joe (J. Am. Stat. Assoc. 100:1009–1020, 2005; Psychometrika 71:713–732, 2006) introduced classes of chi-square tests for (sparse) multidimensional multinomial data based on low-order marginal proportions. Our extension provides general conditions under which quadratic forms in linear functions of cell residuals are asymptotically chi-square. The new statistics need not be based on margins, and can be used for one-dimensional multinomials. We also provide theory that explains why limited information statistics have good power, regardless of sparseness. We show how quadratic-form statistics can be constructed that are more powerful than X ² and yet, have approximate chi-square null distribution in finite samples with large models. Examples with models for truncated count data and binary item response data are used to illustrate the theory.     

Creativity,Schizotypicality, and Mystical Experience: An Empirical Study

This study examined the commonalities and the differences between creativity and the schizophrenia spectrum. The variables measured were creativity, schizotypy, absorption, mystical experiences, spatial ability, balance, positive and negative presence, and neuroticism. Three community groups were recruited: 31 artists, 10 people with schizophrenia, and 31 comparisons matched for gender and age with the artists. A larger student group, consisting of 102 students, was also recruited to examine the correlations among the same variables within a larger, more normative, group. The largest commonality between the artist and the schizophrenic groups was the propensity to mystical experiences. The greatest differences between them were that the artists were higher in creativity, had better spatial ability, had better balance, had more positive states of presence, and were lower in neuroticism. In the student group, creativity was positively correlated with positive schizotypy, impulsive nonconformity, spatial ability, positive presence, absorption, and mystical experiences, although in the student group, the relation between creativity and mystical experiences was completely mediated by absorption.     

We: Commentary on Papers by Trevarthen,Ammaniti & Trentini,and Gallese

In my discussion of papers by Trevarthen, Ammaniti & Trentini, and Gallese, I situate their work within an emerging paradigm of intersubjectivity. This new model finds philosophic grounding in the work of the phenomenologists (Husserl, Merleau-Ponty, Nancy) as it draws from the multiple sources that come together to comprise the new field of cognitive and affective neurosciences. These papers hold the potential to make relational psychoanalysis more relational by providing new foundations for rethinking the biological, developmental and clinical. What emerges is an intersubjective theory based in motor action and perception that serves as the embodied basis for human culture and community, a shared “we” space of basic human affinity. I extend this conception into the analytic setting with a brief introduction to enactive participation in clinical process.     

Principles of polemic in Russell

Three polemical exchanges between Bertrand Russell and F. H. Bradley, F. C. S. Schiller, and the prosecutor in Russell's trial for violating the Defence of the Realm Act in 1916 are examined in order to bring to light some paradigms of informal reasoning, with a view to encouraging research into the logic of natural language. Ten such paradigms are expressed, e.g., Agree with the contention but not for the reasons given; Agree that the criticism is valid and report that one has modified the criticized doctrine but not in the manner suggested.
