The Therapeutic Community Sing: Music Therapy Inpatient Group Process

Early psychoanalytic authors and music educators in both Europe and the United States pointed to the contemporary use of music therapy as a powerful modality in an inpatient psychiatric unit. The inpatient community sing is discussed in its capacity to address both individual and group goals. A clinical vignette from such a group is presented and discussed.     

Explaining Demographic Group Differences in Affirmative Action Attitudes1

This research identified mediators and a moderator of the relationship between demographic category and attitudes toward affirmative action (AA). Data were collected from national samples of sociologists and business academics. The results indicate that racism, traditional attitudes toward women, and belief in the existence of gender and race discrimination in academe were significant predictors of AA attitudes. Several findings provide support for the prediction that these factors mediate the relationship between demographic group membership and AA attitudes. Additionally, male sociologists who believed they personally experienced discrimination had more negative attitudes toward AA. Perceiving personal discrimination increased support of AA among female business academics. Implications for attitude and intergroup conflict theories are discussed.     

The basis of preference for lexical words in 6-month-old infants

Six-month-old English-learning infants have been shown to prefer English lexical over English grammatical words. The preference is striking because there are few grammatical words in total number but each occurs far more frequently in input speech than any individual lexical word. This could be because lexical words are universally more salient and interesting acoustic and phonological forms than are grammatical words. Alternatively, familiarity may play a role since infants may know some specific lexical words. Here we explore the first possibility by testing Chinese-learning infants’ response to English lexical and grammatical words. These infants, who had virtually no prior exposure to English and thus were unfamiliar with any English words, nevertheless preferred to listen to English lexical words, as in the case of English-learning infants. This finding increases the plausibility that it is the acoustic and phonological salience of lexical words that determines the preference for lexical words in infants.     

The need for an evolving concept of validity in industrial and personnel psychology: Psychometric, legal, and emerging issues

The Trinitarian view of validity (namely content, criterion-related, and construct) has dominated psychology for almost a half century. In industrial and personnel psychology especially, content and criterion-related (in particular) forms of validity have served as workhorses. Such a limited focus has lead to a stagnation of the area and the inability to incorporate more theory into the research and practice of personnel psychology. Therefore, we review the evolution of the concept of validity in the psychology discipline, with a particular emphasis on industrial and personnel psychology. We then review the legal and statutory history within industrial and personnel psychology that has helped to shape the concept of validity over the years. Finally, we examine some emerging trends in industrial and personnel psychology, including the issue of graduate training, which may have important consequences on how we conceptualize validity in the future in both our research and practice of personnel psychology.     

“I'll Take Gender Differences for $1000!” Domain-Specific Intellectual Success on “Jeopardy”

A great deal of laboratory research has demonstrated that women underestimate their intellect and abilities, and we studied whether this tendency manifested itself outside the laboratory by examining the performance of men and women on the television game show Jeopardy. Information about the masculinity and femininity of the topic categories for 65 games was collected, and selections, answers,wagering strategies, and earnings were noted for 195 White men and women contestants on the show. Men were more likely than women to appear as contestants, made most of the selections in the game, and won more money. Until the end of the game, men selected and correctly answered a disproportional number of questions from masculine topic categories, which appeared more often during the first round of play. Women chose more feminine and neutral questions than did men, and correctly answered those questions at a proportional rate. Wagering strategies differed late in the game, as men bet a higher percent of their earnings than did women, but only when wagering on masculine topics. Several explanations for differing performance of men and women on Jeopardyare offered, including confidence in ability due to self-estimation of intelligence, differential use of evaluative feedback, and the gender role appropriateness of demonstrating intellect.     

Presentation modality,rehearsal-prevention conditions,and auditory confusions in tests of short-term memory

Ss were presented four-letter sequences either auditorily or visually and asked for ordered recall after 0, 2.1, 4.2, 8.4, or 12.6 sec of digit categorization. Three different rehearsal-prevention conditions were required during presentation of the memory set: categorizing, suppressing (saying "dah"), or pronouncing each letter. Recall was worst after categorizing, best after pronouncing. Auditory presentation led to better recall after no delay but more rapid forgetting than visual presentation, regardless of the rehearsal-prevention condition. These results, and analyses of auditory confusions, are inconsistent with a view of memory which asserts that sensory information is encoded auditorily regardless of presentation modality or vocalization behavior during presentation.     

A two‐part mixed effects model for cigarette purchase task data

The Cigarette Purchase Task is a behavioral economic assessment tool designed to measure the relative reinforcing efficacy of cigarette smoking across different prices. An exponential demand equation has become a standard model for analyzing purchase task data, but its utility is compromised by its inability to accommodate values of zero consumption. We propose a two‐part mixed effects model that keeps the same exponential demand equation for modeling nonzero consumption values, while providing a logistic regression for the binary outcome of zero versus nonzero consumption. Therefore, the proposed model can accommodate zero consumption values and retain the features of the exponential demand equation at the same time. As a byproduct, the logistic regression component of the proposed model provides a new demand index, the “derived breakpoint”, for the price above which a subject is more likely to be abstinent than to be smoking. We apply the proposed model to data collected at baseline from college students (N = 1,217) enrolled in a randomized clinical trial utilizing financial incentives to motivate tobacco cessation. Monte Carlo simulations showed that the proposed model provides better fits than an existing model. We note that the proposed methodology is applicable to other purchase task data, for example, drugs of abuse.
