Ecological influences in youth crisis shelters: Effects of social density and length of stay on youth problem behaviors

For 472 consecutive days we monitored the number of youths residing in a crisis shelter for adolescents, the average length of stay for the youths residing in the shelter on each day, and the number of problem behaviors occurring within the shelter on a daily basis. We analyzed these data using a combination of time series and logistic regression techniques to fit a model that would predict the occurrence of a problem behavior on any given day. After controlling for significant time trends in the data, our results indicate that both the number of youths in the shelter and the proportion of youths who have resided in the shelter longer than 14 days are significantly associated with a problem behavior occurring on any given day. The number of youths in the shelter and the probability of a problem behavior occurring correlated significantly. However, as the proportion of youths who resided in the shelter longer than 14 days increased, the probability of a problem behavior occurring decreased.

The Tree of Life: Universal and Cultural Features of Folkbiological Taxonomies and Inductions

Two parallel studies were performed with members of very different cultures—industrialized American and traditional Itzaj-Mayan—to investigate potential universal and cultural features of folkbiological taxonomies and inductions. Specifically, we examined how individuals organize natural categories into taxonomies, and whether they readily use these taxonomies to make inductions about those categories. The results of the first study indicate that there is a cultural consensus both among Americans and the Itzaj in their taxonomies of local mammal species, and that these taxonomies resemble and depart from a corresponding scientific taxonomy in similar ways. However, cultural differences are also shown, such as a greater differentiation and more ecological considerations in Itzaj taxonomies. In a second study, Americans and the Itzaj used their taxonomies to guide similarity- and typicality-based inductions. These inductions converge and diverge crossculturally and regarding scientific inductions where their respective taxonomies do. These findings reveal some universal features of folkbiological inductions, but they also reveal some cultural features such as diversity-based inductions among Americans, and ecologically based inductions among the Itzaj. Overall, these studies suggest that while building folkbiological taxonomies and using them for folkbiological inductions is a universal competence of human cognition there are also important cultural constraints on that competence.     

Patterns of drug use and criminal activities among latino arrestees in California: Treatment and policy implications

This study examined the patterns of drug use and criminal activities among Latino arrestees. The findings indicate that while the prevalence of drug use at time of arrest, and in the prior 12 months were significantly lower for Latinos compared to Whites and Blacks, drug use still is of concern for this ethnic group. Almost 50% of Latinos reported drug use in the last year, and more importantly, they were more likely to report using dangerous drugs such as cocaine, heroin, and PCP than any other ethnic group. These findings are even more alarming considering that, for the most part, Latino drug users were treatment-naive, and that less than half perceived a need for drug treatment. Regarding criminal activities, Latinos were less likely to have a history of prior arrests and to have been arrested in the year prior to the interview than any other ethnic group. Interestingly, those immigrants who have resided in the U.S. for less than 1 year were significantly more likely to have been charged with drug-related crimes. U.S. born Latinos were more likely to have been arrested for property crimes, while Central American immigrants were more likely than any other Latino group to have been arrested for violent and domestic violence crimes. Treatment and policy implications of these findings are discussed.     

The coincidence effect in similarity and choice

Medin, Goldstone, and Markman (1995) recently described a series of parallel effects in similarity and choice. They suggested that similarity and choice are related in a nontrivial way such that choice may entail a similarity judgment to an explicit or constructed ideal. In this paper, the correspondences between similarity and choice were investigated with respect to a phenomenon in similarity known as thecoincidence effect. In coincidence (pronounced “coincide-ence”), two items that match on one dimension but have a large difference on another dimension receive a higher similarity rating than do two items that have only modest differences on both dimensions. We conducted five experiments in order to examine commonalities between similarity and choice processes with respect to coincidence. Four types of tasks were given: similarity ratings, desirability ratings, forced choice similarities (which of two items is most similar to a target), and forced choice preferences (which of two items one would prefer, given a target). We found a main effect for ratings as opposed to forced choices, with ratings showing greater coincidence effects than did choices. Similarity measures tended to produce more coincidence than did preference measures. The overall pattern of results suggests the presence of dimensional weighting processes sensitive to task characteristics and operating somewhat differently for similarity and decision making.     

Psychological Distress and Help Seeking in Rural America

The implications of exposure to acute and chronic stressors, and seeking mental health care, for increased psychological distress are examined. Research on economic stress, psychological distress, and rural agrarian values each point to increasing variability within rural areas. Using data from a panel study of 1,487 adults, a model predicting changes in depressive symptoms was specified and tested. Results show effects by size of place for men but not for women. Men living in rural villages of under 2,500 or in small towns of 2,500 to 9,999 people had significantly greater increases in depressive symptoms than men living in the country or in larger towns or cities. Size of place was also related to level of stigma toward mental health care. Persons living in the most rural environments were more likely to hold stigmatized attitudes toward mental health care and these views were strongly predictive of willingness to seek care. The combination of increased risk and less willingness to seek assistance places men living in small towns and villages in particular jeopardy for continuing problems involving depressed mood.     

Evaluation and elimination of an avoidance response in a child who stutters: A case study

In this case study, efforts to treat stuttering in a 6-year-old male with cerebral palsy were complicated by frequent replies of “I don't know” that allowed the child to avoid more extensive answers to conversational questions. Following a program of extinction plus differential reinforcement of alternative behavior (DRA), the response “I don't know” was decreased while both speech rate and stuttering increased. Simplified habit reversal (SHR) techniques (controlled breathing) were then applied and resulted in a reduction of stuttering and maintenance of low rates of avoidance. A reversal to baseline resulted in initially high levels of avoidance and low levels of stuttering, with these trends reversing as baseline continued. The SHR treatment for stuttering was then reimplemented and stuttering rates again decreased while avoidance rates remained low, Implications are discussed.
