When people are working on creative tasks, they make progress in conscious thought (CT) and unconscious thought (UT) processes. UT occurs outside conscious awareness, and unlike CT, it is independent of working memory resources. Previous studies suggest UT is more influential under certain conditions, known as the UT effect. Typically, these…

In the standard Proportion-Congruent (PC) paradigm, performance is compared between a list containing mostly congruent (MC) stimuli (e.g., the word RED in the color red in the Stroop task; Stroop, 1935) and a list containing mostly incongruent (MI) stimuli (e.g., the word BLUE in red). The PC effect, the finding that the congruency effect (i.e.,…

The loss of behavioral flexibility is common across a number of neuropsychiatric illnesses. This may be in part due to the loss of the ability to detect or use changes in action-outcome contingencies to guide behavior. There is growing evidence that the ventral hippocampus plays a critical role in the regulation of flexible behavior and…

There is much evidence showing that the prospect of performance-contingent reward increases the usage of cuing information and cognitive stability. In a recent study, we showed that participants under reward conditions even continued using cues even when they were no longer predictive of the required response rule, even at the expense of higher…

Cognitive flexibility refers to various processes which enable behaviors to be modified on the basis of a change in the contingencies between stimuli or responses and their associated outcomes. Reversal learning is a form of cognitive flexibility which measures the ability to adjust responding based on a switch in the stimulus--outcome…

Researchers examined whether contingent experience using a touch screen increased toddlers' ability to learn a word from video. One hundred and sixteen children (24-36 months) watched an on-screen actress label an object: (a) without interacting, (b) with instructions to touch "anywhere" on the screen, or (c) with instructions to touch a…

Taking into account the three key features of scaffolding, namely, contingency, fading and the transfer of responsibility, the present study investigated the role of cognitive scaffolding in speaking and its components (i.e. grammar, vocabulary, pronunciation, discourse management, interactive communication). Moreover, the possible moderating…

In our everyday life, we often need to anticipate the potential occurrence of events and their consequences. In this context, the way we represent contingencies can determine our ability to adapt to the environment. However, it is not clear how agents encode and organize available knowledge about the future to react to possible states of the…

In resurgence, an operant behavior that has undergone extinction can return ("resurge") when a second operant that has replaced it itself undergoes extinction. The phenomenon may provide insight into relapse that may occur after incentive or contingency management therapies in humans. Three experiments with rats examined the impact of several…

Proportion congruency effects represent hallmark phenomena in current theorizing about cognitive control. This is based on the notion that proportion congruency determines the relative levels of attention to relevant and irrelevant information in conflict tasks. However, little empirical evidence exists that uniquely supports such an attention…

The term "pseudocontingency" (PC) denotes the logically unwarranted inference of a contingency between 2 variables X and Y from information other than pairs of x[subscript i], y[subscript i] observations, namely, the variables' univariate base rates as assessed in 1 or more ecological contexts. The authors summarize recent experimental evidence…

Six responses to a study on reinforcement contingencies defined by the response deprivation hypothesis (Stanley Aeschleman and Margaret Williams) note interactions, trends, the role of context, a functional approach to learned performance, the substitutability of responses, and the ecology of reinforcement.

The study with 84 mentally retarded persons (mean IQ 41) concluded that increases of instrumental performance in the response deprivation schedules employed were due to the contingency and not noncontingent deprivation, and that the effectiveness of therapeutic reinforcement programs is influenced by the presence of alternative responses.…

Reinforcement contingencies defined by the response deprivation hypothesis were evaluated with three moderately mentally retarded persons (ages 17, 18, and 19). In the presence of the low probability, freely available response, a consistent reinforcement effect was evident whereas in the presence of a high probability response, the reinforcement…

The authors respond to comments of colleagues concerning their study on reinforcement contingencies defined by the response deprivation hypothesis with moderately mentally retarded persons. They stress the importance of basic research in this area and the need for such research to demonstrate its application to real world problems. (DB)
