Prerequisite vs. in vivo acquisition of self-feeding skill

Separating the acquisition of prerequisite skills from the learning of skills in vivo may be a more efficacious procedure for self-help training of low functioning developmentally delayed children. Two procedures for training independent use of a fork at meals were compared using two equivalent groups of three subjects each, in multiple baseline design. Using previously accepted procedures, one group was trained during meals while the experimental group received prerequisite training making use of simulated food (styrofoam pieces). Data during training, generalization-to-meal, and follow-up were collected. For 6 months following training, the efficacy of prerequisite training was upheld. The complexity of individual responses to the singular or conjunctive use of social and edible reinforcement for the purpose of self-feeding skill generalization and maintenance, is discussed.     

Patterns of intellectual ability in children with verbal deficits

Patterns of intellectual ability were examined in 81 children with verbal deficits identified by a Low Verbal/High Performance WISC profile. The results of verbal and nonverbal tests of intellectual functioning were factor-analyzed, and three groups of children were defined based on patterns of factor scores. Group 1 consisted of children with a Specific Language Disability (SLD) but good Abstract Reasoning ability, while Group 2 included SLD children with good Sequencing-Memory skills. Group 3 children displayed a General Language Disability (GLD) with deficits in both abstract reasoning and sequencing memory. The intellectual patterns were related to cognitive interpretations and found to have educational implications, with Group 1 children reading adequately, Group 2 children showing somewhat poorer reading skills, and Group 3 children reading very poorly. These findings emphasize the importance of identifying subgroups of children with verbal deficits and demonstrate the feasibility of extracting relatively specific cognitive information from global measures of intelligence. The results question the appropriateness of applying traditional assumptions regarding cognitive organization derived from studies of normal children to atypical groups of children.     

STIMULUS CHARACTERISTICS WITHIN DIRECTIVES: EFFECTS ON ACCURACY OF TASK COMPLETION

Three experiments were conducted in an outpatient setting with young children who had been referred for treatment of noncompliant behavior and who had coexisting receptive language or receptive vocabulary difficulties. Experiment 1 studied differential responding of the participants to a brief hierarchical directive analysis (least‐to‐most complex stimulus prompts) to identify directives that functioned as discriminative stimuli for accurate responding. Experiment 1 identified distinct patterns of accurate responding relative to manipulation of directive stimulus characteristics. Experiment 2 demonstrated that directives identified as effective or ineffective in obtaining stimulus control of accurate responding during Experiment 1 continued to control accurate responding across play activities and academic tasks. Experiment 3 probed effects of the interaction between the type of directive (effective vs. ineffective) and the reinforcement contingency (differential reinforcement for attempts vs. differential reinforcement for accurate responses) on accurate task completion and disruptive behavior. Results suggested that behavioral escalation from inaccurate responding to disruptive behavior occurred only when ineffective directives were combined with differential reinforcement for accurate task completion. The overall results are discussed in terms of developing a methodology for identifying stimulus characteristics of directives that affect accurate responding.     

"IF YOU LET ME PLAY SPORTS"

This study tests a model specifying that girls' precollege participation in sporting activities will foster positive body images, enhanced perceptions of physical competence, and more flexible gender identities, which, in turn, predict higher college self-esteem. A sample of 220 college females (mean age = 19.65 years) provided retrospective reports of their precollege sport involvement and contemporaneous assessments of body image, perceived physical competencies, gender identity, global self-esteem, and other psychosocial variables. Consistent with prior reports on male and mixed-gender samples, greater precollege sport participation predicted higher self-esteem in this exclusively female sample. Follow-up path analyses and tests for mediation revealed that the model's intervening variables totally mediated the sport participation/self-esteem relationship. The patterning of these data implies that participating in sports promotes females' self-worth by fostering physical competencies, favorable body images, and gender flexibility, and, in the absence of any such psychosocial benefits, participation in sports has little salutary effect on and can even undermine self-esteem.     

“Watch out!”: Effects of instructed threat and avoidance on human free‐operant approach–avoidance behavior

Approach–avoidance paradigms create a competition between appetitive and aversive contingencies and are widely used in nonhuman research on anxiety. Here, we examined how instructions about threat and avoidance impact control by competing contingencies over human approach–avoidance behavior. Additionally, Experiment 1 examined the effects of threat magnitude (money loss amount) and avoidance cost (fixed ratio requirements), whereas Experiment 2 examined the effects of threat information (available, unavailable and inaccurate) on approach–avoidance. During the task, approach responding was modeled by reinforcing responding with money on a FR schedule. By performing an observing response, participants produced an escalating “threat meter”. Instructions stated that the threat meter levels displayed the current probability of losing money, when in fact loss only occurred when the level reached the maximum. Instructions also stated pressing an avoidance button lowered the threat level. Overall, instructions produced cycles of approach and avoidance responding with transitions from approach to avoidance when threat was high and transitions back to approach after avoidance reduced threat. Experiment 1 revealed increasing avoidance cost, but not threat magnitude, shifted approach–avoidance transitions to higher threat levels and increased anxiety ratings, but did not influence the frequency of approach–avoidance cycles. Experiment 2 revealed when threat level information was available or absent earnings were high, but earnings decreased when inaccurate threat information was incompatible with contingencies. Our findings build on prior nonhuman and human approach–avoidance research by highlighting how instructed threat and avoidance can impact human AA behavior and self‐reported anxiety.     

Out of Darkness: Reverberations of Trauma and its Creative Transformations

Traumatic experiences have a ripple effect, which continues throughout life and function as a powerful inner force that draws the survivor like a magnet to situations and events that allow him or her to work through pain; to give it shape, to release it, to express it to others, to make sense of it and to find some meaning in it. Self-expression through the creative arts can be one of the most effective means to healing. By externalizing what is experienced internally as overwhelming and fragmenting, and by fashioning it into a creative product, the artist brings the traumatic experience into the light of day for a new viewing. This enables reflection and integration of what is internally chaotic to be defined, mastered, and integrated into a coherent meaningful narrative. The artistic product, which can be shared with witnessing others, facilitates connection and fosters a healthy narcissism. The transformation of trauma into creative self-expression is illustrated here by an analysis of three generations of survivors—the author, her father, and her daughter—who each turned to the arts as a means of self-healing.     

Social Exclusion and the Desire to Reconnect

People have a fundamental need to belong that, when satisfied, is linked to a variety of indicators of well‐being. The current article discusses what happens when social relationships go awry, namely through social exclusion. It seeks to resolve discrepancies in the literature by proposing that responses to social exclusion depend primarily on the prospect of social acceptance. When people feel socially excluded, they want to regain acceptance and thus may respond in ways that can help them do so. When the possibility of acceptance is not forthcoming, however, socially excluded people become selfish and antisocial. Evidence for this pattern was found at behavioral, cognitive, and biological levels. The motivation to gain acceptance may drive people to engage in negative health behaviors, such as smoking. Thus, excluded people demonstrate sensitivity to possible social acceptance, but they can exude an air of selfishness and hostility when there is no possibility of satisfying their need to belong.     

A Tale of Two Perspectives: Regulation Versus Self-Regulation. A Financial Reporting Approach (from Sarbanes–Oxley) for Research Ethics

Reports of research fraud have raised concerns about research integrity similar to concerns raised about financial accounting fraud. We propose a departure from self-regulation in that researchers adopt the financial accounting approach in establishing trust through an external validation process, in addition to the reporting entities and the regulatory agencies. The general conceptual framework for reviewing financial reports, utilizes external auditors who are certified and objective in using established standards to provide an opinion on the financial reports. These standards have become both broader in scope and increasingly specific as to what information is reported and the methodologies to be employed. We believe that the financial reporting overhaul encompassed in the US Sarbanes?COxley Act of 2002, which aims at preventing accounting fraud, can be applied to scientific research in 4 ways. First, Sarbanes?COxley requires corporations to have a complete set of internal accounting controls. Research organizations should use appropriate sampling techniques and audit research projects for conformity with the initial research protocols. Second, corporations are required to have the chief financial officer certify the accuracy of their financial statements. In a similar way, each research organization should have their vice-president of research (or equivalent) certify the research integrity of their research activities. In contrast, the primary responsibility of the existing Research Integrity Officers is to handle allegations of research misconduct, an after-the-fact activity. Third, generally accepted auditing standards specify the appropriate procedures for external review of a corporation??s financial statements. For similar reasons, the research review process would also require corresponding external auditing standards. Finally, these new requirements would be implemented in stages, with the largest 14 research organizations that receive 25% of the total National Institutes of Health funding, adopting these research oversight enhancements first.     

Health of Organisms and Health of Persons: An Embedded Instrumentalist Approach

In a time when we as a society are in the process of deciding what our basic rights to health care are, it is critically important for us to have a full and complete understanding of what constitutes health. We argue for an analysis of health according to which certain states are healthy not in themselves but because they allow an individual to reach actual goals. Recognizing that the goals of an individual considered from the point of view of biology and the goals of the same individual considered as an agent in the world might be different, we introduce a distinction between the health of an individual qua organism and the health of an individual qua person. We then argue that this distinction characterizes the evaluations made by patients and healthcare providers better than the widely discussed distinction between disease and illness.
