Definitions of Multicultural Competence: Frontline Human Service Providers' Perspective

In this qualitative study, the authors explored definitions of multicultural competence given by 99 frontline human service providers. The providers had no formal training in counseling but served in a helping role. Seven thematic definitions emerged: color blindness, client focused, acknowledgment of cultural differences, textbook consistent, resource driven, skills‐based, and self‐integrated. Implications for multicultural competence are discussed. En este estudio cualitativo, los autores exploraron las definiciones de competencia multicultural ofrecidas por 99 proveedores de servicios humanos de primera línea. Los proveedores no tenían una formación oficial en consejería, pero actuaban en roles de ayuda. Surgieron como resultado siete definiciones temáticas: indiferente al color, enfocada hacia el cliente, reconocimiento de diferencias culturales, libro de texto, guiada por los recursos, habilidades y autointegrada. Se discuten las implicaciones para la competencia multicultural.     

Object detection and basic-level categorization: Sometimes you know it is there before you know what it is

A tight temporal coupling between object detection (is an object there?) and object categorization (what kind of object is it?) has recently been reported (Grill-Spector &; Kanwisher, 2005), suggesting that image segmentation into different objects and categorization of those objects at the basic level may be the very same mechanism. In the present work, we decoupled the time course of detection and categorization through two task manipulations. First, inverted objects were categorized significantly less accurately than upright objects across a range of image presentation durations, but no significant effect on object detection was observed. Second, systematically degrading stimuli affected categorization significantly more than object detection. The time course of object detection and object categorization can be selectively manipulated. They are not intrinsically linked. As soon as you know an object is there, you do not necessarily know what it is.     

Evaluation of an imputed pitch velocity model of the auditory tau effect

This article extends an imputed pitch velocity model of the auditory kappa effect proposed by Henry and McAuley (2009a) to the auditory tau effect. Two experiments were conducted using an AXB design in which listeners judged the relative pitch of a middle target tone (X) in ascending and descending three-tone sequences. In Experiment 1, sequences were isochronous, establishing constant fast, medium, and slow velocity conditions. No systematic distortions in perceived target pitch were observed, and thresholds were similar across velocity conditions. Experiment 2 introduced to-be-ignored variations in target timing. Variations in target timing that deviated from constant velocity conditions introduced systematic distortions in perceived target pitch, indicative of a robust auditory tau effect. Consistent with an auditory motion hypothesis, the magnitude of the tau effect was larger at faster velocities. In addition, the tau effect was generally stronger for descending sequences than for ascending sequences. Combined with previous work on the auditory kappa effect, the imputed velocity model and associated auditory motion hypothesis provide a unified quantitative account of both auditory tau and kappa effects. In broader terms, these findings add support to the view that pitch and time relations in auditory patterns are fundamentally interdependent.     

Interethnic Relations on Campus: Can't We All Get Along?

This study examined the ethnic climate and relationships between ethnic groups at 5 colleges. Data indicate that White and Latino students were the most comfortable interacting with other ethnic groups, whereas Asians students were the least comfortable. Furthermore, White students had a relatively positive view of the interracial climate in contrast to Black students who described their campuses as more hostile and uninviting.     

Effects of methylphenidate (Ritalin) on information processing in hyperactive children

The effect of methylphenidate on information-processing efficiency was studied in 12 hyperactive, nonretarded children. Performance on six efficiency tasks (Posner Letter Matching, Reaction Time, Memory Search, Category Verification, Item Identification, and Word-Span) and a general measure of on-task behavior were compared for children receiving methylphenidate or a placebo. The median drug dosage was .38 mg/kg, and it was ingested 1 1/2 hours prior to testing. Children blind to the drug-placebo condition were tested on 4 days. In general, methylphenidate-related improvements in attention to on-task behaviors were found. An overall analysis of processing speed suggested that methylphenidate improved efficiency. Methylphenidate significantly decreased reaction times to simple and complex stimulus arrays; differences due to the drug remained even when on-task attentive behaviors were statistically removed. Significantly fewer identification errors occurred on the Posner task in the methylphenidate condition. Results indicated that methylphenidate improved general attentional behaviors and positively influenced processes that define perceptual efficiency.The first author was supported by NIH Training Grant No. HD 07184.

Restrained and unrestrained eating.

Nisbett's (1972) model of obesity implies that individual differences in relative deprivation (relative to set-point weight) within obese and normal weight groups should produce corresponding within-group differences in eating behavior. Normal weight subjects were separated into hypothetically deprived (high restraint) and non-deprived (low restraint) groups. The expectation that high restraint subjects' intake would vary directly with preload size while low restraint subjects would eat in inverse proportion to preload size, was confirmed. It was concluded that relative deprivation rather than obesity per se may be the cirtical determinant of individual differences in eating behavior. Consideration was given to the concept of "restraint" as an important behavioral mechanism affecting the expression of physiologically-based hungar.     

A reexamination of two-point induced movement

Duncker’s (1929) two-point induced movement phenomenon was reexamined to determine whether or not, as Duncker reports, the fixated stimulus is the one which is most likely to appear to move when objective stimulus movement is at or below subject-relative threshold. Data are reported indicating this is not the case.
