Organization of the Self-Concept and the Suppression of Self-Relevant Thoughts

The rebound effect associated with thought suppression has been found following attempts at suppressing both novel stimuli and stereotypical thoughts. However, research examining the suppression of self-relevant thoughts has been less successful in demonstrating the rebound effect. A potential factor that has not yet been fully explored in research on thought suppression is how different types of distracter thoughts may influence the ability to suppress unwanted thoughts. One type of distracter that people may use while attempting to suppress unwanted self-relevant thoughts is information related to other aspects of their lives. To the extent that these other aspects are more likely to be associated in memory with the unwanted thoughts, rebound should be more likely to occur. Thus, we expected and found that people lower in self-complexity (i.e., those with fewer self-aspects that are more interrelated with one another) revealed greater rebound following thought suppression that involved self-relevant distracting thoughts than did people greater in self-complexity. Implications of these findings for thought suppression, self-complexity, depression, and the experience of affect are discussed.     

Maladaptive personality functioning within the big five and the five-factor model

The five-factor model (FFM) of general personality functioning was derived originally from lexical studies of trait terms within the English language. Many studies have been conducted on the relationship of the FFM to personality disorder symptomatology but, as yet, no lexical study of the representation of maladaptive personality functioning within a language has been conducted. The current study identified the distribution of socially undesirable trait terms within each of the poles of the Big Five and compared this distribution to findings obtained with FFM personality disorder measures. The implications of the results for a FFM of personality disorders and for the FFM assessment of maladaptive personality functioning are discussed.     

Tattoos and ratings of personal characteristics

High school and university students viewed a photograph of one woman either with or without a visible tattoo on her upper arm. They rated the woman on 13 personal characteristics (fashionable, athletic, attractive, caring, creative, determined, motivated, honest, generous, mysterious, religious, intelligent, artistic). Analyses showed ratings of the model with the tattoo were statistically significantly lower (more negative) on 9 of the 13 personal characteristics. Ratings were not associated with whether the participants had or did not have tattoos themselves. Implications for research are discussed, including the need to explore the conditions under which negative attitudes may be translated into negative behaviors.     

Pastoral counseling as an echoing process: a transformative therapy hour

The author posits that the essential core of pastoral counseling is an echoing process between client and therapist and between diagnostic listening and restorative responding. He illustrates this process by drawing on the case of a depressed middle-aged client. The therapist's response is described as conveyed through personal presence that is welcoming, participative, courageous, and responsive.     

Concurrent schedules: short- and long-term effects of reinforcers

Five pigeons were trained on concurrent variable-interval schedules in a switching-key procedure. The overall rate of reinforcement was constant in all conditions, and the ratios of reinforcers obtainable on the two alternatives were varied over seven levels. Each condition remained in effect for 65 sessions, and the last 50 sessions of data from each condition were analyzed. The most recently obtained reinforcer had the largest effect on current preference, but each of the eight previously obtained reinforcers had a small measurable effect. These effects were larger when the reinforcer ratio was more extreme. A longer term effect of reinforcement was also evident, which changed as a function of the reinforcer ratio arranged. More local analyses showed regularities at a reinforcer-by-reinforcer level and large transient movements in preference toward the just-reinforced alternative immediately following reinforcers, followed by a return to stable levels that were related to the reinforcer ratio in effect. The present data suggest that the variables that control choice have both short- and long-term effects and that the short-term effects increased when the reinforcer ratios arranged were more extreme.     

How cross-fostered chimpanzees (Pan troglodytes) initiate and maintain conversations

This study systematically sampled typical attention-getting sounds and sign language conversations between each of 4 originally cross-fostered chimpanzees (Pan troglodytes), still living freely, but now in a laboratory setting, and a familiar human interlocutor. Videotape records showed that when they encountered a human interlocutor sitting alone at his desk with his back turned to them, the cross-fosterlings either left the scene or made attention-getting sounds. The only signs they made to the interlocutor's back were noisy signs. When the human turned and faced them, the chimpanzees promptly signed to him (98% of the time) and rarely made any sounds during the ensuing signed conversations. Under systematic experimental conditions, the signed responses of the chimpanzees were appropriate to the conversational styles of the human interlocutor, confirming daily field observations.     

Learning to vary and varying to learn

We compared two sources of behavior variability: decreased levels of reinforcement and reinforcement contingent on variability itself. In Experiment 1, four groups of rats were reinforced for different levels of response-sequence variability: one group was reinforced for low variability, two groups were reinforced for intermediate levels, and one group was reinforced for very high variability. All of the groups experienced three different reinforcement frequencies for meeting their respective variability contingencies. Results showed that reinforcement contingencies controlled response variability more than did reinforcement frequencies. Experiment 2 showed that only those animals concurrently reinforced for high variability acquired a difficult-to-learn sequence; animals reinforced for low variability learned little or not at all. Variability was therefore controlled mainly by reinforcement contingencies, and learning increased as a function of levels of baseline variability. Knowledge of these relationships may be helpful to those who attempt to condition operant responses.     

Context matching and judgments of recency

An experiment was done to test a context-matching explanation of memory for recency under steady-state conditions. Subjects went through a list of 550 names, in which individual names were repeated at lags of 5–30 other items. The names were shown in two different styles or contexts. An old versus new recognition decision was made on each name, and eachold response was followed by a numerical judgment of recency (JOR). When first- and second-presentation contexts were the same, recognition hit rates were higher, and mean JORs were shorter (more recent), than when the two contexts were different. The JOR result is as predicted by the context-matching hypothesis.
