The Importance of Overt Responding in Programmed Instruction Even with Added Incentives for Learning

Among the fundamental tenets of programmed instruction is the requirement of overt responding. Past research has not determined when this tenet holds true. We systematically replicated the work of Tudor (1995) by showing that overt responding in computer-based instruction improves learning, even when there is an incentive that might be thought to improve learning enough to mask the effect of overt responding. Subjects were exposed to both read-only and overt-response materials. One group received course-related, bonus points based on posttest performance, whereas the other group received points simply for participation. Within-subject comparison showed greater performance increases when overt responding was required, regardless of the point incentive. No significant differences were found between groups.     

DISCRIMINATIVE CONTROL OF THERAPISTS' PERFORMANCE1

In order to examine therapists' discriminative responding to normal and idiosyncratic patient responses, naive subjects were presented with a simulated “patient” for treatment. The subjects were made to believe they were reinforcing normal verbalizations emitted by this patient In fact, they were listening to a tape on which normal and idiosyncratic verbalizations had been recorded. Different probabilities of normal and idiosyncratic “patient” verbalizations could be presented to the subjects by means of a digital programming unit. In one of a number of conditions, the subjects' accurate reinforcing responses were followed by an increased probability of the patient's normal verbalizations. Accurate reinforcing responses emitted by the subjects were brought under the control of normal and idiosyncratic patient responses, by use of contingent feedback, change in patient responding, and monetary reinforcers. When the patient's normal verbalizations increased in probability, so did the subjects' accurate reinforcing responses following the patient's normal verbalizations, and to a lesser degree, the subjects' inaccurate reinforcing responses following the patient's idiosyncratic verbalizations. When the patient's idiosyncratic verbalizations increased in probability, the subjects' accurate and inaccurate reinforcing responses decreased in probability. The clinical implications of these tendencies are discussed.     

Elicited responding to signals for reinforcement: the effects of overall versus local changes in reinforcement probability

Pigeons were studied on a three-component multiple schedule where all reinforcement was independent of responding. Two components were cued by different keylights and were associated with different rates of reinforcement. The third was always a no-key period associated with extinction. After a few sessions, pecking was elicited by the keylights signalling the reinforcement and continued to be maintained indefinitely. The duration and sequence of the three components were varied to determine if the primary controlling variable was differences in the overall probability of reinforcement, or if it was the immediate change in reinforcement signalled by the onset and/or offset of the stimulus. Both variables were found to control behavior. When 30-sec components were used, the primary controlling variable was the overall probability of reinforcement, but when 3-min components were used, overall probability had little effect. Control by local changes in reinforcement also occurred, although the type of local control varied both across subjects and experimental conditions. Some behaviors were controlled more by the change in reinforcement signalled by the onset of the stimulus, while others were controlled more by the change signalled by the offset of the stimulus.     

Behavioral contrast of time allocation

Pigeons' standing on a platform produced food reinforcement according to two-component multiple schedules in which either both components consisted of the same variable-interval schedule or one of these was replaced with a component without reinforcement (extinction). The components of the multiple schedule alternated every 30 sec, and were signalled by changes in the color of diffuse overhead illumination. Changing the schedule of one of the components to extinction increased the percentage of time spent on the platform during the unchanged component (behavioral contrast). This result casts doubt on accounts that attribute behavioral contrast to variations in the rate of noninstrumental elicited responses.     

Relationship maintenance across platonic and non-platonic cross-sex friendships in emerging adults

Prior research examining maintenance in cross-sex friendships focuses heavily on platonic (i.e., nonsexually active) friendships with limited research examining sexually involved cross-sex friendships (i.e., “friends with benefits relationships”). In this study, we investigated differences in relational maintenance behaviors between sexually and nonsexually active cross-sex friendships types. In an online survey, 531 emerging adult participants from large southwestern and southeastern universities identified either a friends with benefits or platonic opposite sex friendship and then completed items asking them to report the frequency with which they enacted each of 36 relationship maintenance behaviors. Overall, participants involved in casual sex friendships engaged in the least, and those who transitioned from a friends-with-benefits relationship to a romantic relationship engaged in the most frequent relationship maintenance. Platonic friendships employed more frequent maintenance than casual-sex friendships but less than either true friends with benefits or participants who transitioned to a romantic relationship.     

大学生依恋焦虑与抑郁的关系:恋爱中关系攻击和关系质量的序列中介作用

浪漫关系中的关系攻击指通过操纵或损害关系以达到伤害浪漫关系伴侣的行为。本文以628名处于恋爱关系中的大学生为被试,探讨了依恋焦虑与抑郁之间的关系,并考察了恋爱中的关系攻击和恋爱关系质量在其中的序列中介作用。结果表明:(1)大学生依恋焦虑对抑郁有显著的正向预测作用;(2)关系攻击和关系质量在大学生依恋焦虑与抑郁之间分别发挥着单独中介作用;(3)关系攻击和关系质量在大学生依恋焦虑与抑郁之间发挥着序列中介作用。研究结果验证了依恋焦虑个体在关系中的“自我实现预言”模型,同时能够为大学生心理健康教育提供实践指导。     

不只是“谈话疗法”：精神分析治疗中的非言语维度

精神分析治疗在很长一段时间里被视为“谈话疗法”,其治愈机制是将潜意识的内容意识化,语言解释在其中发挥关键作用。自20世纪末开始,越来越多分析师强调非言语交流在治疗中的作用。非言语交流不仅能够为咨访双方提供更丰富的交流形式,还能通过互动中的“相遇时刻”,实现对患者过去经验的重组,改变其有缺陷的内隐关系知晓。非言语交流和语言交流能够在治疗中发挥互补作用,未来的精神分析心理学要继续加强对非言语领域的研究。     

Training class inclusion responding in typically developing children and individuals with autism

In a class inclusion task, a child must respond to stimuli as being involved in two different though hierarchically related categories. This study used a Relational Frame Theory (RFT) paradigm to assess and train this ability in three typically developing preschoolers and three individuals with autism spectrum disorder, all of whom had failed class inclusion tests. For all subjects, relational training successfully established the target repertoire and subsequent testing demonstrated both maintenance and generalization. Limitations and future research directions are discussed.     

The relationship between differential stimulus relatedness and implicit measure effect sizes

Implicit measures have been hypothesized to allow researchers to ascertain the existence and strength of relations between stimuli, often in the context of research on attitudes. However, little controlled behavioral research has focused on whether stimulus relations, and the degree of relatedness within such relations, are indexed by implicit measures. The current study examined this issue using a behavior‐analytic implicit‐style stimulus relation indexing procedure known as the Function Acquisition Speed Test (FAST). Using a matching‐to‐sample (MTS) procedure to train stimulus equivalence relations between nonsense syllables, the number of iterations of the procedure was varied across groups of participants, hence controlling stimulus relatedness in the resulting equivalence relations. Following final exposure to the MTS procedure, participants completed a FAST. Another group of participants was exposed to a FAST procedure with word pairs of known relatedness. Results showed that increasing relatedness resulted in a linear increase in FAST effect size. These results provide the first direct empirical support for a key process‐level assumption of the implicit literature, and offer a behavior‐analytic paradigm within which to understand these effects. These results also suggest that the FAST may be a viable procedure for the quantification of emergent stimulus relations in stimulus equivalence training.
