We manipulated two parameters of response blocking to reduce pica: (a) the criteria for initiating the procedure (either earlier or later in the response chain) and (b) the distance from which the procedure was initiated. Results suggested that response blocking may be effective only when implemented early in the chain and with near-perfect consistency. Further, additional treatment components may be required to eliminate all pica attempts.
(a)启动该程序的标准(在反应链中更早或更晚启动)以及(b)启动该程序的距离。结果表明,反应阻断可能仅在反应链早期实施且具有近乎完美的一致性时才有效。此外,可能需要额外的治疗组件来消除所有异食癖行为。
