Differential reinforcement of alternative behavior increases resistance to extinction: clinical demonstration, animal modeling, and clinical test of one solution

Basic research with pigeons on behavioral momentum suggests that differential reinforcement of alternative behavior (DRA) can increase the resistance of target behavior to change. This finding suggests that clinical applications of DRA may inadvertently increase the persistence of target behavior even as it decreases its frequency. We conducted three coordinated experiments to test whether DRA has persistence-strengthening effects on clinically significant target behavior and then tested the effectiveness of a possible solution to this problem in both a nonhuman and clinical study. Experiment 1 compared resistance to extinction following baseline rates of reinforcement versus higher DRA rates of reinforcement in a clinical study. Resistance to extinction was substantially greater following DRA. Experiment 2 tested a rat model of a possible solution to this problem. Training an alternative response in a context without reinforcement of the target response circumvented the persistence-strengthening effects of DRA. Experiment 3 translated the rat model into a novel clinical application of DRA. Training an alternative response with DRA in a separate context resulted in lower resistance to extinction than employing DRA in the context correlated with reinforcement of target behavior. The value of coordinated bidirectional translational research is discussed.     

Neighborhoods as a Developmental Context: A Multilevel Analysis of Neighborhood Effects on Head Start Families and Children

Neighborhoods have been recognized in theory and research as an important context for child development. This study used data from the Head Start Family and Child Experiences Survey (FACES) and Census 2000 to assess the underlying factor structure and impact of neighborhood factors on child cognitive and behavioral outcomes, including the critical family and social factors that may mediate and/or moderate these relationships. Factor analyses found five factors described Head Start neighborhoods. After controlling for family and child factors, multilevel analyses found significant direct effects of neighborhood factors on Head Start children’s cognitive and behavioral outcomes. There were no mediation effects found for family or social variables between neighborhood factors and child outcomes. A large number of moderation effects were found although there was not a clear pattern to the results. Future research, policy, and practice implications are discussed.     

Examining lateralized semantic access using pictures

A divided visual field (DVF) experiment examined the semantic processing strategies employed by the cerebral hemispheres to determine if strategies observed with written word stimuli generalize to other media for communicating semantic information. We employed picture stimuli and vary the degree of semantic relatedness between the picture pairs. Participants made an on-line semantic relatedness judgment in response to sequentially presented pictures. We found that when pictures are presented to the right hemisphere responses are generally more accurate than the left hemisphere for semantic relatedness judgments for picture pairs. Furthermore, consistent with earlier DVF studies employing words, we conclude that the RH is better at accessing or maintaining access to information that has a weak or more remote semantic relationship. We also found evidence of faster access for pictures presented to the LH in the strongly-related condition. Overall, these results are consistent with earlier DVF word studies that argue that the cerebral hemispheres each play an important and separable role during semantic retrieval.     

Considerations for the Use of Sentence Completion Tests

Often, sentence completion tests are administered to clients without a clear sense of the clinical questions to be investigated, and, therefore, the appropriate sentence completion instrument to be used. The multitude of forms that have evolved in the last fifty years have made it difficult for clinicians to make informed decisions about which form to use and for what purpose. This article presents ten general guidelines or considerations for the effective use of this popular but sometimes misused psychological assessment method. Practitioners are urged to consider such issues as oral versus written presentation of items, item content in terms of positive or negative stimulus pull, the structure of sentence stems, the original purpose of a given test in regard to intended population and theoretical orientation of the author, and the empirical validity of tests.     

Not without hope: a Reformed analysis of sickness and sin.

A Reformed understanding of sickness requires that connections be drawn between the structural effects of sin and the ways that sickness is experienced in people's lives. Such an understanding can be an important resource for the bioethicist, both the bioethicist who speaks from the Reformed tradition and the bioethicist who speaks to patients and caregivers who may assume that sin and sickness are connected, but may understand that linkage in overly simplistic ways.     

Sustained withdrawal behavior in clinic‐referred and nonreferred infants

To examine the relations between infants' sustained withdrawal behavior and children's mental health status and maternal and child relational behavior, 36 clinic‐referred and 43 control infants were evaluated. Families were visited at home, mother‐child free play and feeding interactions were videotaped, and mothers completed self‐report measures. Interactions were coded for sustained withdrawal using the Alarm Distress Baby Scale (ADBB; Guedeney and Fermanian, 2001) and for global relational patterns with the Coding of Interactive Behavior (CIB; Feldman, 1998). Higher ADBB scores were found for the referred group, with many infants (38.9% ) scoring above the clinical cutoff (vs. 11.6% in the control group). More negative relational patterns were found for the withdrawn group in terms of higher maternal intrusiveness, lower reciprocity, and lower child involvement. Associations were found between maternal and child behavior during play and feeding and child sustained withdrawal behavior at play. Sustained withdrawal also was associated with unpredictable child temperament and lower sense of parental self‐efficacy. Maternal depressive symptoms were higher in the referred group and correlated with maternal and child relational patterns. The findings contribute to the construct and discriminant validity of the CIB and the ADBB coding systems, and suggest that sustained withdrawal may serve as a risk indicator for early socioemotional disorders.     

Rational emotive behavior therapy successes and failures: Eight personal perspectives

Eight experts in Rational Emotive Behavior Therapy (REBT) provided personal examples of their own successes and failures in applying REBT to themselves. The experts actively talked to themselves both rationally and irrationally. Understandably, there were far more shoulds, oughts, musts, and have to’s in the narratives in which the experts described when they failed to use REBT than when they succeeded in using REBT. Rational self-talk was more prevalent in the examples of how REBT was successfully used by the experts. Reprinted from Journal of Counseling & Development, Summer 2001, Volume 79. ACA.

Intergroup relations and the attribution of emotions: control over memory for secondary emotions associated with the ingroup and outgroup

This study tested the hypothesis that people perceive their ingroup as experiencing more uniquely human secondary emotions than the outgroup. Jacoby's process-dissociation procedure was used to measure participants' controlled recognition memory for materials that associated the ingroup or outgroup with secondary or primary emotions. Conscious memory was better for associations between the outgroup and secondary emotions than for associations between the ingroup and secondary emotions. No such difference was found for primary emotions. These results suggest that people attribute more humanity to the ingroup than to the outgroup.     

Affect expression in prenatally psychotropic exposed and nonexposed mother–infant dyads

This prospective study examined infant, maternal, and dyadic affective profiles at three months postpartum in infant–mother dyads that were exposed to psychotropic medications in utero compared with nonexposed control dyads. Control dyads of nondepressed mothers and their infants showed many similarities in affect expression with mother–infant dyads who were exposed to selective serotonin reuptake inhibitors (SSRIs) alone for treatment of maternal depression. In contrast, mothers who received SSRIs and Rivotril (Benzodiazepine derivative) for treatment of depression and anxiety expressed both positive and negative affect towards their infants. Clinical implications regarding use of psychotropic medications such as SSRIs alone or in combination with other drugs for treatment of maternal anxiety and depression during pregnancy are discussed. Clinicians should be aware of the possible differential response in maternal–infant interaction in a mixed diagnosis group (i.e., depression and anxiety) regarding infant temperament, possibly suggesting latent behavioral teratogenicity with psychotropics. ©2002 Michigan Association for Infant Mental Health.
