The effect of training on visual alignment discrimination and grating resolution.

The effect of training on an observer's ability to detect the misalignment of three points, a hyperacuity, and to resolve a six-line grating was studied in a transfer-of-training design with observers (4 in each of two experiments) who were experienced in making psychophysical judgments of other visual stimuli. The transfer-of-training design enabled us to look for any training-based improvement. Long periods of training produced no statistically significant improvement in performance under any condition. There were small practice-based improvements, but the primary patterns indicated threshold fluctuation rather than improvement. We interpret the results to indicate that the neural mechanisms underlying three-point alignment and grating discrimination, like those for gap bisection (Klein & Levi, 1985), are not malleable to any significant extent.

Sex-related effects on clinicians' attributions of parental responsibility for child psychopathology

An attempt was made to reproduce and extend previously reported data suggesting the operation of sex-related bias in clinicians' attributions of parental involvement in children's psychopathologies. More and less sex-role traditional male and female family-oriented practitioners were shown contrived profiles in which a boy or girl was described as masculine or feminine role-deficient, and apportioned maternal versus paternal blame, treatment focus, adjunctive therapy need, and likelihood of sabotage. As in the previous study, mothers were implicated slightly more than fathers and also were viewed as requiring relatively greater therapeutic attention by female than by male clinicians. However, several earlier findings were not replicated. Overall, the results offer only marginal support for the notion of sex-related practitioner bias.     

“Applied” research can be useful: An example

an example of how a practitioner can use his research skills to help a school district evaluate one of its projects is described. The practitioner is advised to become involved in “action” research despite the limitations of such research, and the example is presented as having implications for expanding the psychologist's role to that of a consultant to administrators, teachers, and parents.     

Systematic Review and Quality Appraisal of Practice Guidelines for Self‐Harm in Children and Adolescents

This study aimed to systematically identify and appraise clinical practice guidelines (CPGs) relating to the assessment and management of suicide risk and self‐harm in children and adolescents. Our research question is as follows: For young people (under 18 years old) presenting to clinical care with suicide ideation or a history of self‐harm, what is the quality of up‐to‐date CPGs? Using the PRISMA format, we systematically identified CPGs meeting our inclusion and exclusion criteria. Subsequently, two independent raters conducted appraisals of the eligible CPGs using the Appraisal of Guidelines for Research and Evaluation II instrument. CPGs were then classified as “poor quality,” “minimum quality,” and “high quality” using operationally defined criteria developed a priori. We identified 10 eligible CPGs published or renewed between 2005 and May 2017. Only the long‐term management of self‐harm CPGs produced by the National Institute for Health and Care Excellence met “high‐quality” criteria. Despite multiple options of CPGs published to choose from, only one was identified as “high quality,” where bias is adequately minimized. Clinicians are advised to direct resources to implementing the “high‐quality” CPG.     

The training of community mental health clinicians as infant specialists

This article describes the training program and collaborative effort between the Department of Mental Health, the Child Development Project at the University of Michigan, and community mental health agencies. The in-service training is described with special attention to content and process, including the role of case supervision. The effect of the training program as a catalyst to service development is noted.     

Interaction between catecholaminergic and opioid systems in an active avoidance task

Male NMRI mice were given intravenous injections of the noradrenergic neurotoxin DSP4 or the vehicle 24 to 72 h prior behavioral testing. Animals were given 2 days of training on a one-way active avoidance task. Naloxone was given in one of three doses prior to training on Day 1 and Day 2 or prior to training on Day 1 only (saline was given prior to training on Day 2). There was a dose-dependent impairment of acquisition by naloxone in the vehicle-pretreated groups; 10 mg/kg naloxone produced a significant impairment of acquisition. Naloxone also modulated retention (Day 2) performance of the active avoidance task. For vehicle-pretreated mice, 1 mg/kg naloxone facilitated and 10 mg/kg naloxone-impaired performance on Day 2. DSP4 alone produced an impairment of acquisition of this task but had no effect on retention; Day 2 scores were slightly higher in the DSP4-pretreated group than in the vehicle-pretreated group. Naloxone produced somewhat different effects in DSP4-pretreated animals than in vehicle-pretreated animals. Naloxone (1 mg/kg) ameliorated the DSP4-induced impairment of acquisition; 10 mg/kg naloxone did not significantly alter the acquisition performance of this group. For the DSP4-pretreated mice that received naloxone before training on both days, the dose-response characteristics for retention scores were similar to those of vehicle-pretreated mice; 1 mg/kg naloxone was the facilitatory dose. However, for DSP4-treated mice that received naloxone before training on Day 1 only, there was a shift to the right in the effective facilitatory dose of naloxone. For these animals, 10 mg/kg naloxone but not 1 mg/kg naloxone significantly enhanced retention performance. We discuss these results in the context of a possible state-dependent modulation by naloxone in the DSP4-treated animals.     

“I’ve said I’m sorry,haven’t I?” A study of the identity implications and constraints that apologies create for their recipients

In contrast to previous research on apologies, which has examined their role in enhancing impressions of those issuing them (e.g., Darby and Schlenker, 1989), the research reported here draws upon Goffman’s (1955) analysis of the “corrective cycle” and is concerned with constraints associated with the receipt of apologies. Study 1 examines the implications for the actor of accepting, not accepting, or rejecting apologies. It is demonstrated that across a variety of judgments, most positive views of the actor result when apologies are accepted; least positive views are associated with their rejection. A follow-up study sought to establish whether this effect would occur under circumstances in which unconvincing apologies are rejected. Results indicate that the apology’s status (convincing versus unconvincing) has no bearing on perceptions of actors. Based on a hypothetical role-play format, Study 2 addresses the matter of whether actors experience a subjective sense of constraint upon receipt of unsatisfactory apologies. The data suggest that there exists a pronounced tendency to accept such apologies, though typically with conditions that would be specified to the offender. More general implications of the data are discussed.
