Despite increasing interest in the psychological assessment of adolescents, no test usage surveys have specifically targeted practitioners who work with teenagers. This study involved distribution of research surveys to 600 psychologists; the 165 respondents who provided usable data yielded an adjusted response rate of 36%. The Wechsler Intelligence Scales, the Rorschach, and the Minnesota Multiphasic Personality Inventory (MMPI) were identified as the most widely used intellectual, projective, and objective instruments, respectively, with adolescents. The Bender-Gestalt, Thematic Apperception Test (TAT), sentence completion tests, figure drawings, and the Wide Range Achievement Test (WRAT) were also included in the 10 most frequently used instruments. Data were also presented on standard test batteries used with adolescent clients, and advantages and disadvantages associated with the use of the MMPI.Adolescents have been the focus of extensive research interest in recent years, and a number of clinical measures and tests have been developed specifically for use with this age group. Assessment of adolescents has received increased coverage in many current texts that deal mainly with testing or assessment (e.g.,
Surveys regarding practitioner perceptions of time requirements for psychological testing were mailed to a national sample of clinical psychologists. There were 228 (36%) returns from 630 mailings actually received. On the basis of 151 usable returns from respondents who conduct psychological testing services, data are presented separately for time requirements associated with administering, scoring, and interpreting the 24 most commonly used tests. Data are also presented regarding the composition of typical test batteries and practitioner usage of technician and/or computer assistance in psychological testing. The implications of these data for research and practice are discussed.
We demonstrate the use of multiple atomic-level Rydberg-atom schemes for continuous frequency detection of radio frequency (RF) fields. Resonant detection of RF fields by electromagneticallyinduced transparency and Autler-Townes (AT) in Rydberg atoms is typically limited to frequencies within the narrow bandwidth of a Rydberg transition. By applying a second field resonant with an adjacent Rydberg transition, far-detuned fields can be detected through a two-photon resonance AT splitting. This two-photon AT splitting method is several orders of magnitude more sensitive than off-resonant detection using the Stark shift. We present the results of various experimental configurations and a theoretical analysis to illustrate the effectiveness of this multiple level scheme. These results show that this approach allows for the detection of frequencies in continuous band between resonances with adjacent Rydberg states.
We demonstrate a two dimensional grating magneto-optical trap (2D GMOT) with a single input cooling laser beam and a planar diffraction grating using 87 Rb. This configuration increases experimental access when compared with a traditional 2D MOT. As described in the paper, the output flux is several hundred million rubidium atoms/s at a mean velocity of 16.5(9) m/s and a velocity distribution of 4(3) m/s standard deviation. We use the atomic beam from the 2D GMOT to demonstrate loading of a three dimensional grating MOT (3D GMOT) with 2.46(7) × 10 8 atoms. Methods to improve output flux are discussed.
We present a method for generating precise, dynamically tunable magnetic potentials that can be described by a polynomial series along the axis of a cold-atom waveguide near the surface of an atom chip. With a single chip design consisting of several wire pairs, various axial potentials can be created by changing the ratio of the currents in the wires, including double wells, triple wells, and pure harmonic traps with suppression of higher-order terms. We use this method to design and fabricate a chip with modest experimental requirements. Finally, we use the chip to demonstrate a double-well potential.
