Timing at the Start of Associative Learning

Some theories of associative learning imply that time plays a fundamental role in the acquisition process. Consistent with these theories, this paper presents evidence that the time from the onset of a conditioned stimulus (CS) until presentation of the unconditioned stimulus (US) is learned very rapidly at the start of training. We report two autoshaping studies and a study on aversive conditioning in goldfish in which we examine timing at the start of conditioning. We also review data from a number of other conditioning preparations, including fear-potentiated startle, appetitive conditioning in rats, and eyeblink conditioning in rabbits, that report conditioned response (CR) timing early in training. Acquisition speed and the very first expressions of conditioned responding often show sensitivity to the time of US presentation. In instances where temporal control is slowly expressed, it is likely due to performance factors, not to slow learning about time. In fact, the learning about time may be a necessary condition for associative learning.     

The Problem of Transfer from Confidential Interactive Problem‐Solving: What Is the Role of the Facilitator?

Interactive problem-solving workshops provide a relatively confidential atmosphere in which members of societies engaged in protracted social conflict can examine and share their assumptions and perceptions about the conflict and think creatively about the possibilities for de-escalation. Two sorts of workshop goals have generally been articulated: (1) creating change in participants' understanding, and (2) transferring participants' new ideas to political decision-making and public discussion. Although facilitators have tended to emphasize the role of the participants in generating and transferring new learning, this article expands our conceptions of change and transfer to include both participants and facilitators. A basic complementarity is postulated between the strengths and weaknesses of these two agents of transfer. If considered this way, the integrity of this confidential process—and thus of its potentially unique contributions to a peace process—can be maintained while increasing the opportunities for transfer.     

The Transracial Adoption Debate: Counseling and Legal Implications

Over the last 30 years, the practice of White American parents adopting African American children has been the focus of much deliberation and commentary. In this article, the authors illuminate relevant literature and research regarding transracial adoption. Counseling and legal implications are also discussed.     

Confidence at the group level of analysis: A longitudinal investigation of the relationship between potency and team effectiveness

Our longitudinal field study investigated the relationship between team potency and team effectiveness. The sample for this study was drawn from 71 change management teams from an automotive firm in the USA. Team potency ratings were obtained from team members. Team effectiveness ratings were obtained from team members, team leaders and external raters. Results indicated that team effectiveness and team potency are reciprocally and longitudinally related (p< .01).     

Structural limits on verb mapping: the role of abstract structure in 2.5‐year‐olds’ interpretations of novel verbs

Two experiments showed that 2.5‐year‐olds, as well as older children, interpret new verbs in accord with their number of arguments. When interpreting new verbs describing the same motion events, children who heard transitive sentences were more likely than were children who heard intransitive sentences to assume that the verb referred to the actions of the causal agent. The sentences were designed so that only the number of noun‐phrase arguments differed across conditions (e.g. She’s pilking her over there versus She’s pilking over there). These experiments isolate number of noun‐phrase arguments (or number of nouns) as an early constraint on sentence interpretation and verb learning, and provide strong evidence that children as young as 2.5 years of age attend to a sentence’s overall structure in interpreting it.     

Group decision process and incrementalism in organizational decision making

In two studies examining resource allocation, support is found for the notion that group decisions are affected in systematic ways depending on whether or not there was individual consideration of the problem before meeting as a group. Specifically, compared to no prior consideration groups, prior consideration groups (1) escalate their commitment more in progress (i.e., ongoing) decisions, and (2) are less willing to concentrate resources on a single project in adoption (i.e., resource utilization) decisions. The findings challenge the blanket assertion that promoting divergent views in a group decision context is always related to better decisions.     

Consequences of Feeling Dissimilar from Others in a Work Team

This study extended the current literature on group diversity by examining the moderating influence of perceived group openness to diversity on the relationships between perceived individual visible, informational, and value dissimilarity; individual task and relationship conflict; and work group involvement. A survey was administered to 129 public service employees who worked in intact teams. Results revealed that value dissimilarity had a positive association with task and relationship conflict and a negative association with work group involvement. Perceived group openness to diversity moderated the associations between visible and informational dissimilarity and work group involvement, and between value dissimilarity and task conflict. These results highlight the importance of managing differences by introducing norms promoting diversity and the involvement of all team members.     

The Protestant Work Ethic,Expectancy Violations,and Criminal Sentencing1

To test the hypothesis that endorsement of the Protestant work ethic would be related positively to sensitivity to criminal behavior that violated expectations, American college students (N = 159) read scenarios describing a crime committed by a typical or an atypical offender. After answering questions about the crime, they completed Mirels and Garrett's (1971) Protestant Work Ethic (PWE) scale. Extent of punishment was positively related to PWE for atypical criminal behavior. Yet, high PWEs also were more likely to perceive an affluent criminal as experiencing greater remorse for a blue‐collar crime than a white‐collar crime. We relate our results to perceptions of criminal behavior, information‐processing tendencies among individuals endorsing the PWE, and jury selection considerations.

Toxicosis affects instrumental behaviour in rats

Three experiments examined the effect of toxicosis on instrumental responding. These studies were prompted by Morrison and Collyer's (1974, Experiment 1) finding that the induction of toxicosis after an instrumental conditioning session produces greater response suppression if the response is reinforced by a novel saccharin solution rather than familiar water during conditioning. Experiments 1 and 2 investigated whether this suppression was mediated by the Pavlovian contingency between the contextual cues and the saccharin solution or the instrumental relationship between the response and the reward. A role for the instrumental contingency was indicated by the greater suppression of the response producing novel saccharin rather than water when the context of both responses was equally associated with the saccharin and illness. Experiment 3 found that extinction of the aversion to a novel reinforcer following aversive conditioning would re-establish an action previously associated with that reinforcer, in contrast to an action whose reinforcer remained aversive. This result was a further indication that the instrumental contingency between the response and reward contributes to response suppression.
