An evaluation of simultaneous presentation and differential reinforcement with response cost to reduce packing

We evaluated the effects of multiple treatment procedures, including simultaneous presentation of preferred foods, on the packing behavior of a 9-year-old girl with autism. A reversal design was used to assess the effects of differential reinforcement with response cost alone and with simultaneous presentation. In addition, simultaneous presentation was assessed independent of differential reinforcement with response cost. Results indicated that simultaneous presentation reduced packing and that differential reinforcement with response cost was not necessary to maintain these reductions. Results are discussed in terms of the use of simultaneous presentation for packing as an alternative to consequence manipulations.     

Dispositional forgiveness of self, others, and situations

Six studies regarding forgiveness are presented. The Heartland Forgiveness Scale (HFS), a self-report measure of dispositional forgiveness (with subscales to assess forgiveness of self, others, and situations) was developed and demonstrated good psychometric properties. Forgiveness correlated positively with cognitive flexibility, positive affect, and distraction; it correlated negatively with rumination, vengeance, and hostility. Forgiveness predicted four components of psychological well-being (anger, anxiety, depression, and satisfaction with life); forgiveness of situations accounted for unique variance in these components of psychological well-being. Forgiveness and hostility demonstrated equivalent, inverse associations with relationship duration, and forgiveness accounted for unique variance in relationship satisfaction, even when controlling for trust. Forgiveness level correlated positively with decreased negativity in statements written about transgressions in the present versus the past tense.     

Psychometric Assessment of the Comprehensive Effects of Alcohol Questionnaire: Comparing a Brief Version to the Original Full Scale

The current set of studies compared the psychometric properties of the original Comprehensive Effects of Alcohol Questionnaire (CEOA) to a 15-item version (B-CEOA) in a nonclinical undergraduate sample (N = 581), and attempted to replicate and extend the B-CEOA findings in an undergraduate sample referred to an alcohol intervention (N = 734). Psychometric assessment included construct validity, internal consistency, and concurrent validity, using both positive and negative expectancy items in all analyses. Results provided further support for the empirical validity of the original CEOA, and provided support for the use of the B-CEOA despite the reduction in the number of items. The B-CEOA factor structures obtained using exploratory and confirmatory techniques provided support for a 4-factor structure of expectancies and 3-factor structure of valuations. Findings reveal potential problems with positive and negative expectancy items. Trade-offs regarding factor structure, internal consistency, and administration time should be considered in using the B-CEOA vs. the CEOA.     

Rhythmic masking release: effects of asynchrony, temporal overlap, harmonic relations, and source separation on cross-spectral grouping

The rhythm created by spacing a series of brief tones in a regular pattern can be disguised by interleaving identical distractors at irregular intervals. The disguised rhythm can be unmasked if the distractors are allocated to a separate stream from the rhythm by integration with temporally overlapping captors. Listeners identified which of 2 rhythms was presented, and the accuracy and rated clarity of their judgment was used to estimate the fusion of the distractors and captors. The extent of fusion depended primarily on onset asynchrony and degree of temporal overlap. Harmonic relations had some influence, but only an extreme difference in spatial location was effective (dichotic presentation). Both preattentive and attentionally driven processes governed performance.     

Stroop dilution revisited: evidence for domain-specific, limited-capacity processing

Nine experiments show that in the context of Stroop dilution the extent to which flanking distractors are processed depends on the nature of the material at fixation. A Stroop effect is eliminated if a word or a nonword is colored and appears at fixation and the color word appears as a flanker. A Stroop effect is observed when the color carrier at fixation is from a different domain than the color word distractor (e.g., Arabic digits). It is argued that when the material at fixation is in the same domain as the color word distractor, the distractor is not processed. Taken together, these results implicate a role for material-specific, limited-capacity processing in the context of this variant of the Stroop paradigm.     

Sudden gains in cognitive behavioral treatment for depression: when do they occur and do they matter?

Despite the use of efficacious treatments for depression, individuals differ in both the degree to which they recover and the rate at which recovery occurs. Tang and colleagues found that depressed patients who had sudden improvements in their symptomatology not only maintained these gains, but also enjoyed more improvement and higher rates of recovery than those without sudden gains (J. Consulting Clin. Psychol. 67(6) (1999) 894; J. Consulting Clin. Psychol. 70(2) (2002) 444). Our study examined the role of sudden gains in a cognitive-behavioral group treatment for depression. Results indicated that 41.9% of patients experienced sudden gains. Furthermore, sudden gains occurring in the first third of treatment appear to have special importance. Participants enjoying early sudden gains had significantly larger changes in depressive symptom scores over the course of treatment than those without sudden gains and were marginally more likely to be treatment responders compared to those without early sudden gains. In contrast to Tang and DeRubeis (J. Consulting Clin. Psychol. 67(6) (1999) 894), however, sudden gains were not associated with cognitive changes.     

A taxometric investigation of unipolar depression in the national comorbidity survey

Ongoing debate has questioned whether unipolar depression is a dimensional or categorical phenomenon. Although past studies using taxometric methods have supported a dimensional interpretation, each has suffered from methodological limitations. The present study was designed to overcome these limitations through reanalysis of the National Comorbidity Survey. Two indicator sets were constructed from the depression-relevant questions of the Composite International Diagnostic Interview. Participants who endorsed the lifetime occurrence of significant depressed mood or anhedonia (n=4,577) were submitted to 2 nonredundant taxometric procedures (maximum eigenvalue and means above minus below a cut), additional consistency tests, and recently developed simulation techniques. All results converged on a dimensional solution. The implications of these findings on assessment, treatment, and research design are discussed.     

Transparency and self-disclosure in family therapy: dangers and possibilities

Therapy is a paid intimate relationship that thrusts clients and therapists into navigating personal and professional boundaries. When, where, why, and how is it appropriate and ethical for family therapists to be transparent, and when is it damaging? Theorists take varied stances from Haley's position of tight boundaries around therapist disclosure—whether in treatment or training—to the narrative viewpoint that therapists should be transparent about models of therapy, personal values, and life experiences that inform their practice and beliefs. However, these positions are not research based, and theorists who support disclosure offer few guidelines other than general statements. This article examines the history of ideas about disclosure in six major family therapy models, and the dangers and possibilities of transparency. It looks at the research on self‐disclosure in individual therapy and whether and how it could apply to family therapy. Guidelines are proposed that take into account the multiple social identities of therapists and clients, and issues of safety and transparency.     

Some Thoughts about the Hardest Logic Puzzle Ever

The Hardest Logic Puzzle Ever was first described by the late George Boolos in the Spring 1996 issue of the Harvard Review of Philosophy. Although not dissimilar in appearance from many other simpler puzzles involving gods (or tribesmen) who always tell the truth or always lie, this puzzle has several features that make the solution far from trivial. This paper examines the puzzle and describes a simpler solution than that originally proposed by Boolos.
