Internal-external control of reinforcement and embedded-figures performance

Male and female Ss were tested in an extended series of 68 embedded figures. Rate of decrease in discovery time was related to Ss’ attitudes about locus of control of reinforcing outcomes. Results confirmed those of an earlier study, showing that practice dissipated sex-related performance differences observable in early trials.     

Genetically-determined abnormal behavior in dogs: Results of behavioral tests

Starting with relatively stable and with very timid purebred pointer stock, we have accumulated data on exploratory activity, reactions to a loud noise, and reactions to friendly and threatening humans which demonstrate clear-cut strain differences. These differences appear as early as 2 months on some tests, and later at early maturity on others. A general factor of fear or timidity explains most of the atypical behavior of the unstable animals. Further, the consistency of results over three generations of offspring suggests a relatively simple mode of autosomal inheritance.     

Effect of person on nervous,stable and crossbred pointer dogs

Through selective mating and line breeding of pointer dogs we have developed and continued two strains which are fairly behaviorally distinct. We now have data accumulating from the crossing of these two lines. Although the offspring from the crosses are still young, it can be seen that some stable male parents have had nonenvironmental, i.e., genetic, effects. The offspring are in many respects like their nervous mothers, but in some behavior, notably social behavior, they can be mistaken for the stable strain of dog. Heart rates have mimicked those of the nervous mothers and seem in no way influenced by the stable ancestry in “Effect of Person” tests. There is a marked difference between stable and unstable dogs in the effect of “Person” on heart rate: the unstable dogs show practically no cardiac response to “Person” (petting), whereas the normal dogs show the usual marked bradycardia to petting.     

A technique for correlating measurable traits with freely observed social behaviors

In much research in social psychology it is impractical to get quantitative measure of the degree of effectiveness of certain social behaviors, yet associates can sense that effectiveness sufficiently well to detect those who manifest the behavior in very high or in very low degree. This paper develops a technique of biserial correlation from wide-spread classes to deal statistically with such situations, develops standard error formulas for it, and points to a wide range of usefulness for this type of technique.     

Mental Health Diagnostic Considerations in Racial/Ethnic Minority Youth

Misdiagnoses of racial/ethnic minority youth’s mental health problems can potentially contribute to inappropriate mental health care. Therefore, we conducted a systematic review that focuses on current theory and empirical research in an attempt to answer the following two questions: (1) What evidence exists that supports or contradicts the idea that racial/ethnic minority youth’s mental health problems are misdiagnosed? (2) What are the sources of misdiagnoses? Articles were reviewed from 1967 to 2014 using PsychINFO, PubMed, and GoogleScholar. Search terms included “race”, “ethnicity”, “minority”, “culture”, “children”, “youth”, “adolescents”, “mental health”, “psychopathology”, “diagnosis”, “misdiagnosis”, “miscategorization”, “underdiagnosis”, and “overdiagnosis”. Seventy-two articles and book chapters met criteria and were included in this review. Overall, evidence was found that supports the possibility of misdiagnosis of ethnic minority youth’s emotional and behavioral problems. However, the evidence is limited such that it cannot be determined whether racial/ethnic differences are due to differences in psychopathology, mental health biases, and/or inaccurate diagnoses. Cultural and contextual factors that may influence misdiagnosis as well as recommendations for research and practice are discussed.     

Teaching behavior analysts in an early intensive behavioral intervention setting to conduct a structured mealtime protocol

Children with autism spectrum disorder often display feeding problems, such as consumption of a limited variety of foods. It is also common for these children to be enrolled in early intensive behavioral intervention (EIBI) services for comprehensive treatment. Combined, these factors make it possible that behavior analysts will have a role in a child's clinical care related to feeding. However, given that the etiology of pediatric feeding disorders is complex and multifactorial, clinicians should ensure they have sufficient training and a setting that is appropriate for assessment and treatment. Therefore, we evaluated the effects of behavioral skills training in an EIBI setting to conduct a structured mealtime protocol. Training resulted in increases in procedural integrity, and we replicated these effects for all participants.
