Parafoveal processing of transposed-letter words and nonwords: evidence against parafoveal lexical activation

The current experiments explored the parafoveal processing of transposed-letter (TL) neighbors by using an eye-movement-contingent boundary change paradigm. In Experiment 1 readers received a parafoveal preview of a target word (e.g., calm) that was either (1) identical to the target word (calm), (2) a TL-neighbor (clam), or (3) a substituted-letter (SL) nonword (chem). In Experiment 2 a further set of parafoveal preview conditions was explored including (4) an SL-word condition (chum) and (5) a TL-nonword condition (caml). Across both experiments, readers' fixation durations on the target words were significantly longer when the previews were SL previews than when they were TL neighbors, suggesting that TL neighbors (when presented in the parafovea) facilitate processing rather than inhibit processing. Experiments 3 and 4 showed that this is in contrast to the inhibitory effects that are seen when TL neighbor previews appear in the fovea.     

Self-Report Measures to Identify Post Traumatic Stress Disorder and/or Mild Traumatic Brain Injury and Associated Symptoms in Military Veterans of Operation Enduring Freedom (OEF)/Operation Iraqi Freedom (OIF)

Individuals serving in Iraq and Afghanistan sustain injuries associated with physical and psychological trauma. Among such injuries, mild traumatic brain injury (mTBI) and post traumatic stress disorder (PTSD) are common. Self-report measures are frequently used to identify mTBI and/or PTSD and symptoms associated with these conditions. In addition to providing information regarding mTBI and PTSD, the goal of this literature review was to identify and present information on the psychometric properties of measures used to obtain information regarding these common conditions among Veterans who have returned from Operation Enduring Freedom (OEF)/Operation Iraqi Freedom (OIF). A comprehensive review of studies in which self-report measures were used to evaluate mTBI, PTSD, and associated symptoms among OEF/OIF Veterans is presented. Findings suggest that additional work is needed to identify psychometrically sound and clinically useful self-report measures that assess mTBI and PTSD and associated symptoms among OEF/OIF Veterans.     

A Model of Faking Likelihood in the Employment Interview

There has been surprisingly little research on faking in the employment interview, despite the fact that professional judgment would suggest that faking might occur in the interview. Based on a review of the literature on faking in personality tests and the literature on deception, we propose a model of faking during an employment interview and develop 19 testable propositions to guide future research. We argue that faking is a function of capacity, willingness, and opportunity to fake. Structured interviews provide less opportunity for intentional distortion; however, some components of structure may actually increase faking. Finally, job candidates distort their responses in job desirable ways.     

CONTINGENCY MANAGEMENT INTERVENTIONS: EFFECTS ON TREATMENT OUTCOME DURING METHADONE DETOXIFICATION

We examined the effectiveness of a contingency management program in preventing relapse to illicit opiate use and increasing treatment retention during outpatient methadone detoxification treatment. Twenty male opiate addicts were randomly assigned to an experimental or control group. Following a 3-week methadone stabilization period, men in both groups received identical gradual methadone dose reductions during Weeks 4 through 9 and were maintained on placebo during Weeks 10 through 13. Beginning in Week 4, control patients received $5.00 for providing a specimen twice weekly. Experimental patients received $10.00 and a take home methadone dose for each opiate-free urine specimen but forfeited the incentives and participated in more intensive clinic procedures when specimens were opiate positive. The contingency management procedure slowed the rate of relapse to illicit opiate use. Experimental patients provided significantly more opiate-free urines during the methadone dose reduction in Weeks 4 through 9 than control patients, although the difference between groups was no longer significant during placebo administration in Weeks 10 through 13. In addition, the contingency management program improved treatment retention and reduced symptom complaints during the detoxification. The usefulness and limitations of contingency management procedures for outpatient methadone detoxification are discussed.     

Developmental changes in infants' sensitivity to octave-band noises

Localization responses to octave-band noises with center frequencies at 200, 400, 1000, 2000, 4000, and 10,000 Hz were obtained from infants 6, 12, and 18 months of age. During an experimental trial, an octave-band noise was presented on one of two speakers located 45° to each side of the infant. A head turn to the noise (correct response) was rewarded by activating an animated toy on top of the speaker. The intensity of the noise was varied over trials (method of constant stimuli) to determine thresholds at each center frequency. Thresholds for the lower frequencies were approximately 5–8 db higher in the 6-month-old infants compared to the older infants. However, there were no consistent differences among groups at the higher frequencies. Infant thresholds were found to be 20–30 db higher than adult thresholds at the lower frequencies. At the higher frequencies thresholds for infants were approaching those of adults.     

Parental guilt: The part played by the clinical geneticist

Parents of children born with a disability often suffer feelings of inappropriate guilt and shame. Although some genetic counselors see their main task to be that of diagnosis and education, they also aim to relieve these feelings of guilt and shame. Little is known about the process of genetic counseling, and whether or not counselors achieve this aim. An exploratory study of one clinic, and one geneticist working with 30 families, using video recordings and taped interviews, indicated that this particular doctor sometimes succeeded in reducing guilt, either intentionally or unintentionally, but on one occasion guilt was iatrogenic, and increased rather than decreased. Further research is needed to examine other types and other styles of genetic counseling so that in future iatrogenic guilt can be avoided, and the distressing aspects of inappropriate guilt and shame reduced as much as possible.
