A multiple case study of teachers’ visions and reflective practice

Researchers have found that teachers’ visions of what they hope to instill in their students beyond curricular objectives are integral to their instruction and to larger decisions such as their career paths. The purpose of this research was to examine 10 in-service teachers, who taught in different geographic locations across the United States, their visions, and the ways in which these visions influenced their reflective curricular decisions and instructional actions. The researchers describe salient dimensions of visions, the actions teachers reported to enact visions, and the distance and tensions in enacting visions. Researchers used grounded theory and constant comparative analysis to analyze interviews, questionnaires, and artifacts. Findings explore the relationship between teachers’ visions and reflective practice as well as the alignment of instructional practices teachers report in supporting their respective visions. Implications for future research, theory, and practice are discussed.     

Adolescents with Turkish background in Norway and Sweden: a comparative study of their psychological adaptation

Using a questionnaire survey, this study compared psychological adaptation (self-esteem, life satisfaction, and mental health problems) of Turkish adolescents in Norway and Sweden, and examined to what extent ethnic and majority identities, acculturation strategies, and perceived discrimination accounted for adaptation among Turkish adolescents. The samples consisted of 407 Turks (111 in Norway and 296 in Sweden) with a mean age of 15.2 years and 433 host adolescents (207 in Norway, 226 in Sweden) with a mean age of 15.6 years. Turks in Norway reported poorer psychological adaptation than Turks in Sweden. Predictors of good adaptation were Turkish identity and integration, whereas poor adaptation was related to marginalization and perceived discrimination. The results indicated that the poorer adaptation of Turks in Norway compared to that of Turks in Sweden could be due to lower degree of Turkish identity and higher degree of perceived discrimination.     

Assessment of deviant arousal in adult male sex offenders with developmental disabilities

Ten individuals, residing in a treatment facility specializing in the rehabilitation of sex offenders with developmental disabilities, participated in an arousal assessment involving the use of the penile plethysmograph. The arousal assessments involved measuring change in penile circumference to various categories of stimuli both appropriate (adult men and women) and inappropriate (e.g., 8- to 9-year-old boys and girls). This approach extends the existing assessment literature by the use of repeated measurement and single-subject experimental design. Data from these assessments were analyzed to determine if clear and informative outcomes were obtained. Overall, three general patterns of results emerged. Some participants showed differentiated deviant arousal or higher levels of arousal to specific inappropriate stimuli (deviant is a term used in the existing sex-offender literature to describe this type of arousal). Other participants showed undifferentiated deviant arousal, in which case they showed nonspecific arousal to inappropriate stimuli. The remaining participants showed no arousal to inappropriate stimuli but did show arousal to appropriate stimuli. Implications for assessment, treatment, and future directions are discussed.     

Enhancing job-site training of supported workers with autism: a reemphasis on simulation

Currently recommended practice in supported work emphasizes training job skills to workers with severe disabilities while on the job. Early behavioral research indicated that skills needed in natural environments could also be trained in simulated settings. We compared job-site plus simulation training for teaching job skills to supported workers with autism to provision of training exclusively on the job. Job-site training occurred in a small publishing company during the regular work routine, and simulation training occurred in an adult education site for people with severe disabilities. Two pairs of workers received training on two job skills; one skill was trained at the job site and the other was trained using job-site plus simulation training. Results indicated that for 3 of the 4 comparisons, job-site plus simulation training resulted in a higher level of skill or more rapid skill acquisition than did job-site-only training. Results suggested that job-site training, the assumed best practice for teaching vocational skills, is likely to be more effective if supplemented with simulation training. Directions for future research include expanding applications of behavioral technologies to other aspects of the current support paradigm.     

Consumer Preference Programs for Individuals Who Are Homeless and Have Psychiatric Disabilities: A Drop-In Center and a Supported Housing Program

We illustrate Fairweather's approach to Experimental Social Innovation and Dissemination with two experimental studies of programs to reduce homelessness for 168 and 225 people with mental illness and often substance abuse. Literally homeless participants were randomly assigned to programs that emphasized consumer choice or to the usual continuum of care, in which housing and services are contingent on sobriety and progress in treatment. A drop-in center that eliminated barriers to access to services was more successful than control programs in reducing homelessness, but after 24 months only 38% of participants had moved to community housing. A subsequent apartment program, in which individuals in the experimental condition moved to subsidized apartments directly from the street, with services under their control, had 79% in stable housing (compared to 27% in the control group) at the end of 6 months. Groups in this study did not differ on substance abuse or psychosocial outcomes.     

Emotion facilitates perception and potentiates the perceptual benefits of attention

Does emotion affect how people see? We investigated the effects of emotion and attention, as well as their conjoint effect, on contrast sensitivity, a dimension of early vision. We manipulated the emotional valence and the attentional distribution of cues preceding a target stimulus and asked observers to judge the orientation of the target as contrast varied. This study provides the first behavioral evidence that (a) emotion enhances contrast sensitivity irrespective of attention and (b) emotion potentiates the effect of attention on contrast sensitivity.     

Can Florida become like the next Florida? When metaphoric comparisons fail

Metaphors can be understood in either of two ways: via a comparison process or via a categorization process. What determines which process will be used? According to a recent variant of comparison theory, novel metaphors must be processed as comparisons; only conventional metaphors can be processed as categorizations. We argue that choice of process is determined not by conventionality, but instead by the semantic and referential properties of the metaphor itself. We identified a type of novel metaphor that is indeed understood more quickly as a comparison than as a categorization. We then generated variants of such metaphors to make comparison difficult and found that these new novel metaphors were understood more quickly as categorizations than as comparisons. We conclude that metaphors can be processed as categorizations from the start, depending on their semantic and referential properties.     

Effects of post-training hippocampal injections of midazolam on fear conditioning

Benzodiazepines have been useful tools for investigating mechanisms underlying learning and memory. The present set of experiments investigates the role of hippocampal GABA(A)/benzodiazepine receptors in memory consolidation using Pavlovian fear conditioning. Rats were prepared with cannulae aimed at the dorsal hippocampus and trained with a series of white noise-shock pairings. In the first experiment, animals received intrahippocampal infusion of midazolam or vehicle immediately or 3 h after training. Then, 24 h later, freezing to the training context and the white noise were measured independently. Results show infusion of midazolam immediately, but not 3 h, after training selectively attenuates contextual fear conditioning. In the second experiment, animals received intrahippocampal infusions of an antisense oligodeoxynucleotide (ODN) targeting the alpha5 subunit of the GABA(A) receptor or a missense control for several days prior to training and testing. Immediately after training, animals received an infusion of either midazolam or vehicle. Western blots conducted after testing showed a significant decrease in alpha5-containing GABA(A) receptor protein. This reduction did not alter the effectiveness of midazolam immediately after training at impairing context fear memory. Therefore, alpha5-containing GABA(A) receptors may not contribute to the effects of midazolam on context fear conditioning when given immediately post-training.
