The scale of ethnic experience: development and psychometric properties

The Scale of Ethnic Experience (SEE) is a new self-report instrument designed to measure multiple ethnicity-related cognitive constructs across ethnic groups. We present the development and psychometric properties here. We generated and refined an item pool using expert consultants and culturally diverse focus groups. We derived a final 32-item version of the SEE based on separate factor analyses of data from college students in 4 ethnic groups: African Americans, Caucasian Americans, Filipino Americans, and Mexican Americans. Four factors were consistent across the ethnic groups: Ethnic Identity, Perceived Discrimination, Mainstream Comfort, and Social Affiliation. We found evidence of test-retest reliability, internal consistency, and criterion and construct validity for all groups. Finally, we cross-validated the factor structure of the SEE in a culturally diverse sample. Results support the reliability and validity of the SEE as a multidimensional measure of ethnicity-related cognitive constructs that can be used across American ethnic groups.     

Bridging the gap between laboratory and applied research on response-independent schedules

In 1948, Skinner described the behavior of pigeons under response-independent schedules as “superstitious,” and proposed that the responses were reinforced by contiguous, adventitious food deliveries. Subsequently, response-independent schedules have been of interest to both basic and applied researchers, first to understand the mechanisms involved, and later, as “noncontingent reinforcement” (NCR) to reduce undesirable behavior. However, the potential superstitious effects produced by these schedules have been challenged, with some researchers arguing that antecedent variables play a significant role. This paper examines the evidence for adventitious reinforcement from both laboratory and applied research, the results of which suggest that antecedent, nonoperant functions may be important in fully understanding the effects of NCR. We propose an applied-basic research synthesis, in which attention to potential nonoperant functions could provide a more complete understanding of response-independent schedules. We conclude with a summary of the applied implications of the nonoperant functions of NCR schedules.     

Artifact in pain ratings,its implications for test-retest reliability,and correction by a new scaling procedure

The conventionally employed procedure for rating ischemic pain was found to produce a degree of response bias associated with the ceiling points of the scale used. A new approach permitting open-ended ratings followed by transformation of these ratings into a common decile scale provided far greater test-retest reliability. This was explained largely in terms of the attenuation of rating artifact. The new procedure also gave rise to consistently linear functions for ischemic pain. Implications are raised for the measurement of pain as well as other psychological continua.     

Integrating systems of care in california for youth with severe emotional disturbance II: Initial group home expenditure and utilization findings from the California AB377 Evaluation Project

The California AB377 Evaluation Project was established to study the replication of an innovative system of care in three California counties for youth suffering from severe emotional disturbance. Development of the innovative system of care was pioneered in Ventura County, California, and the replications were legislatively enabled through Assembly Bill 377 (AB377). This paper reports evaluative findings about a central goal of the innovative care system: the reduction of use of highly restrictive out-of-home placements though creation and maintenance of coordinated and effective community-based services. Group home facilities are the focus of the evaluation work because these facilities consume the largest proportion of all public expenditures for youth in residential placements in California. More than 10 years of aggregate county and state level monthly expenditure and utilization data are presented. The results indicate that the demonstration counties have generated lower per capita inflation adjusted rates of expenditures and per capita group home placements than California as a whole. The evaluation results provide evidence that an integrated system of care can reduce group home placements. However, the nature, quality and effectiveness of any and/or all alternative services provided remains a topic for further investigation.     

An "open-transformed scale" for correcting ceiling effects and enhancing retest reliability: the example of pain

The use of closed scales (with anchors at each end) to measure pain was found to produce ceiling effects characterized by a deceleration of ratings toward the upper end of the scale. This was consistent with previous research. Apart from producing nonlinear functions, the closed scale also limited test-retest reliability because of subjects' tendencies to correct their distorted ratings in subsequent trials. However, an open-ended scale coupled with transformation of reported ratings into a decile scale virtually eliminated the ceiling effect, thus producing consistently linear functions and maximizing test-retest reliability. This finding may have implications for the measurement of other sensory and psychological phenomena, especially those in which the property evaluated varies in a continuous fashion.     

Portuguese category norms for children

This study presents Portuguese category norms for children of three different age groups: preschoolers (3- to 4-year-olds), second graders (7- to 8-year-olds), and preadolescents (11- to 12-year-olds). Three hundred Portuguese children (100 in each group) completed an exemplar-generation task. Preschoolers generated exemplars for 13 categories, second graders generated exemplars for 17 categories, and preadolescents generated exemplars for 21 categories. For each group, responses within each category were organized according to frequency of production in order to derive exemplar-production norms for sets of tested categories. The results also included information about the number of responses and exemplars, idiosyncratic and inappropriate responses, and commonality and diversity indexes for all the categories. A comparison of these children's norms with the Portuguese adult norms was also presented. The full set of norms may be downloaded from www.psychonomic.org/archive.     

Effect of Heel Heights on Female Postural Control During Standing on a Dynamic Support Surface With Sinusoidal Oscillations

The authors aimed to investigate female balance or stability control with comparative analysis of the center of pressure trajectory and plantar pressure distribution with different high-heeled shoes while standing on a dynamic surface with multidirectional perturbations. College females with at least 2 years' history of wearing high-heel shoes voluntarily participated in the test with a Novel Pedar insole (Novel, GmBH, Munich, Germany. With heels height increasing, the pressure time integral obviously transfer to the medial forefoot region, with center of pressure trajectory medially deviated significantly, either under anteroposterior or mediolateral perturbations. The passive plantarflexion position of ankle incurred by high heel increased the range of motion in the frontal plane but decreased ankle stability, thus increasing the challenge of body balance maintenance.     

Rorschach Comprehensive System data for a sample of 506 adult nonpatients from Argentina

This study is composed of 506 nonpatient adults, ages 18 to 65, all from Argentina. The data were gathered by five examiners, who tested most of the participants at their work site. Inclusion and exclusion criteria are described and interrater reliability statistics at the response level are presented along with findings for the Rorschach Comprehensive System (CS; Exner, 1994).     

Depressed mothers' newborns show less discrimination of other newborns' cry sounds

Newborns' crying in response to the cry of another newborn has been called an empathetic response. The purpose of this study was to determine whether newborns of depressed mothers showed the same response. Newborns of depressed and non-depressed mothers were presented with cry sounds of themselves or other infants, and their sucking and heart rate were recorded. The newborns of non-depressed mothers responded to the cry sounds of other infants with reduced sucking and decreased heart rate. In contrast, the newborns of depressed mothers did not show a change in their sucking or heart rate to the cry sounds of other infants. This lesser attentiveness/responsiveness to other infants' cry sounds may predict their later lack of empathy.
