Contrasting the ironic monitoring and motivational explanations of postsuppressional rebound

Suppressing a thought often results in postsuppressional rebound, that is, a subsequent increase in the incidence of the suppressed thought. The present study was dcsigned to distinguish between two explanations of rebound: Wegner's 1994 ironic monitoring theory and Liberman and Forster's 2000 motivational account. Participants (99 Deakin University students) first suppressed, then expressed, thoughts of a white bear. In some conditions, a delay--presented as occurring either intentionally or unintentionally--between suppression and expression was introduced. In other conditions, participants concurrently completed a memory task and were encouraged to antribute the difficulty of suppression either to this task or to the requirement of suppression. An intentional delay, but not an unintentional delay, reduced rebound, while attributing difficulty to the suppression requirement was associated with greater rebound than was attributing it to the memory task. The results are interpreted as supporting Liberman and Forster's motivational account of rebound.     

Similarity on the rebound: inhibition of similarity assessment leads to an ironic postsuppressional rebound

A widely held but rarely tested assumption among cognitive scientists is that different cognitive tasks may rely upon a single basic cognitive process. Using an established methodology to examine the suppression and subsequent rebound of mental operations, the present research indicates that suppressing use of similarity in one domain results in the subsequent rebound of similarity assessment in a different domain, suggesting that both domains rely on the same underlying cognitive process. In two studies, we demonstrate that leading people to suppress natural similarity assessment in one task produces increased reliance on similarity in subsequent, different, and apparently unrelated tasks. In Experiment 1, participants led to suppress similarity in a concentration task subsequently made more errors in a false-memory paradigm than did control participants. In Experiment 2, participants suppressing similarity in a categorization task made more false-memory errors and perceived more similarity between word pairs than participants who did not suppress. The findings suggest that the cognitive process of similarity assessment may be a domain-general process, such that it is widespread across a number of different mental tasks.

The role of attribution of motivation in producing postsuppressional rebound

Three studies demonstrated that postsuppressional rebound (PSR) may be both reduced and enhanced by manipulating people's attributions about why they experience difficulty during suppression. Telling participants that suppression failures indicate a high motivation to use the suppressed construct produced more PSR than telling them that suppression failures indicate a low motivation to use the construct (Study 1). Telling participants that an external stimulus would make suppression easy produced more PSR than telling them that it would make suppression difficult (Study 2). Telling participants that suppressing a stereotype is difficult and unindicative of prejudice eliminated PSR (Study 3). These results support the notion that PSR occurs because people infer from the difficulty experienced during suppression and from suppression failures that they are motivated to use the suppressed construct.     

Controlling your mind without ironic consequences: Self-affirmation eliminates rebound effects after thought suppression

Thought suppression can ironically lead to a rebound of unwanted thoughts [Wegner, D. M. (1994). Ironic processes of mental control. Psychological Review, 101, 34-52.]. The present research explored whether self-affirmation may eliminate rebound effects after thought suppression. Participants either suppressed or used stereotypes in an impression formation task. Subsequently, self-affirmation was manipulated by providing participants with positive or neutral personality feedback, and stereotype accessibility was assessed. The results showed that suppression led to a rebound of stereotypic associations among neutral-feedback participants, but not among positive-feedback participants. The authors conclude that self-affirmation enhances the efficiency of mental control.     

Similarity as threat: A motivational explanation of self–other similarity judgment asymmetry

People tend to judge others to be more similar to themselves than themselves are to others. This self–other similarity judgment asymmetry was often explained by a cognitive model. However, some findings were inconsistent with this model, implying that there might be complementary processes underlying such asymmetry. Although a motivational explanation has been proposed to account for the asymmetry, little evidence has been accumulated to verify this explanation and differentiate it from the cognitive model. The current research tested both the core assumption of the motivational explanation as well as a hypothesis derived only from it. Results suggest that the perception of oneself as being similar to others was more threatening to people's uniqueness than the perception of others as being similar to oneself. Individuals with high need for uniqueness exhibited greater asymmetry than did individuals with low need. Copyright © 2015 John Wiley & Sons, Ltd.     

A saccadic suppression explanation of the Pulfrich phenomenon

A latency explanation of the Pulfrich phenomenon of binocular vision provides for the seen path with an oscillating pendulum to be symmetrical and at right angles to the line of sight. Since the experience of asymmetries in the seen path of a pendulum, when viewed with one eye filtered, is more than the exception, an explanation which has the potential to provide for both symmetry and asymmetry is to be preferred. A saccadic suppression explanation offers this possibility. A saccadic suppression explanation would provide that vision would be suppressed in the filtered eye first followed by suppression in the unfiltered eye. Both eyes would recover vision simultaneously. The predicted resultant disparate stimulation is consistent in direction with that necessary to the Pulfrich phenomenon. The details of the required stimulation have been checked using simple and compound episcotisters. The results with the episcotisters are consistent with the Pulfrich phenomenon.     

An experimental evaluation of tic suppression and the tic rebound effect

Tourette's syndrome (TS) is a neurobiological disorder consisting of motor and vocal tics that are thought to be temporarily suppressible. Many professionals, however, believe that a paradoxical increase in tic frequency (above baseline levels) occurs when efforts to suppress have ceased (i.e., a rebound effect). To date, little research has investigated tic suppression or its effects. This study examined tic frequency during baseline, suppression, and post-suppression conditions using an experimental preparation reported to reliably produce tic suppression in children. Six children with TS and one with chronic tic disorder (CTD) were recorded during baseline and repeated suppression and post-suppression conditions. Tic frequency was significantly lower during suppression as compared to baseline. Although tic frequency during post-suppression was higher than during suppression, it was lower than baseline levels, arguing against a "rebound" effect of tic suppression. Exploratory analyses revealed that scores on the attention problems subscale of the Child Behavior Checklist significantly predicted tic suppressibility. The relationships between age, tic severity, and tic suppressibility were also explored.     

Hindsight bias after receiving self-relevant health risk information: a motivational perspective

The phenomenon of hindsight bias was explored in the context of self-relevant health risk information. Participants in a community screening estimated their cholesterol level (foresight measure) before receiving positive or negative feedback based on their actual cholesterol level. Hindsight estimations were then assessed twice: once immediately after the feedback, and again several weeks later. While the unexpected positive feedback group showed no systematic recall bias, hindsight estimations of individuals receiving unexpectedly negative feedback showed a dynamic change over time. Immediately after the feedback, participants' recollection of their expected cholesterol level were shifted towards their actual cholesterol level (hindsight bias). In contrast, several weeks later, foresight estimations were recalled as less accurate than they had been (reversed hindsight bias). These data might reflect a change of the motivational focus from "hot affect" and fear control, which occur immediately after receiving negative feedback, to danger control, which occurs some time after the feedback, as proposed by the dual process model.     

Positive conditioned suppression: an explanation in terms of multiple and concurrent schedules

Rats performed under a baseline variable-interval schedule of food presentation. A response-independent food schedule was then superimposed on the baseline schedule for different periods of time across different conditions. The response-independent schedule operated for the whole session in some conditions, intermittently for sixty second periods in some, and intermittently for ten-second periods in others. Under these latter two sets of conditions, the response-independent food schedule was stimulus correlated and alternated with the baseline schedule according to a multiple schedule. Response-independent food presentations always suppressed responding. The degree of suppression tended to increase the longer the period of response-independent food. Control conditions, in which the superimposed schedule was response-dependent, rather than response-independent, did not produce response suppression. The results fit an analysis of positive conditioned suppression phenomena in the context of multiple and concurrent schedule effects.

Sneaking in through the back door: How category-based stereotype suppression leads to rebound in feature-based effects

Given the dramatic shifts in societal norms to curb overt stereotyping and prejudice, these biases may leak out in more subtle ways than were apparent in the past. Accordingly, we examined how the suppression of stereotypes might affect post-suppression category-based stereotyping and the more subtle feature-based stereotyping. In support of our proposition, participants in the suppression condition used more feature-based, but less category-based stereotypes in their post-suppression task than participants in the control condition. Furthermore, a relation between post-suppression category-based and feature-based stereotyping existed in the suppression condition such that decreases in category-based stereotyping were associated with increases in feature-based stereotyping. Findings as a whole suggest that norms against the expression of stereotypic biases may ironically lead people to be more vulnerable to biases as a function of within-category features.

Performance and motivational deficits of helplessness: the role of motivational orientations

The present study examined the hypothesis that the effect of failure feedback in producing learned helplessness would depend on the motivational orientation of a child. Extrinsically motivated children were predicted to exhibit performance decrement following a failure experience, whereas the opposite was predicted for intrinsically motivated children. In addition, success feedback was predicted to enhance subsequent performance only for the intrinsic group. Following success, failure, or no feedback on an activity reflecting spatial skills (an incomplete picture task), subjects' performance on an activity tapping different skills (i.e., anagrams) provided by a second experimenter served as the primary measure of helplessness. Subjects' intrinsic motivation in performing the incomplete picture task, a similar task (embedded figures) and a dissimilar task (dots-to-dots) was also examined. The results supported the predictions on both performance and intrinsic motivation measures. The results are discussed in terms of implications for learned helplessness as well as cognitive evaluation theories.     

Interference suppression vs. response inhibition: An explanation for the absence of a bilingual advantage in preschoolers’ Stroop task performance

The well-documented advantage that bilingual speakers demonstrate across the lifespan on measures of controlled attention is not observed in preschoolers’ performance on Stroop task variations. We examined the role of task demands in explaining this discrepancy. Whereas the Color/Word Stroop used with adult participants requires interference suppression, the Stroop task typically used with preschoolers requires only response inhibition. We developed an age-appropriate conflict task that measures interference suppression. Fifty-one preschool children (26 bilinguals) completed this new Bivalent Shape Task and the Day/Night task used in previous research. Bilingual in comparison to monolingual children performed better on incongruent trials of the Bivalent Shape Task, but did not differ on other measures. The results indicate that the discrepancy between preschoolers and older individuals in performance on Stroop task adaptations results from characteristics of the task rather than developmental differences. Further, the findings provide additional support for the importance of interference suppression as a mechanism underlying the bilingual advantage.     

Conscientiousness in the classroom: a process explanation

Although the research literature has established that Conscientiousness predicts task performance across a variety of achievement contexts (e.g., ; ), comparatively less is known about the processes that underlie these relations. To the latter end, the current research examines effortful strategies and achievement goals as mediating factors that might explain why people with higher levels of Conscientiousness are predicted to reach higher levels of academic performance. In a longitudinal study, 347 college students completed measures of personality and achievement goals at the beginning of the class, followed by measures of effortful strategies multiple times throughout the semester. Results support the hypothesis that effortful strategies mediate the association between Conscientiousness and academic performance. Moreover, the statistical effects of Conscientiousness were generally independent of achievement goals, but a small portion of the effect was mediated through approach, not avoidance, achievement goals. These results highlight the importance of examining mediating processes between personality and outcomes, and in the case of Conscientiousness, our results suggest that effortful strategies might serve as a useful target for performance-enhancing interventions.     

Higher frequency of left-breast cancer: a possible explanation

A study of 1027 women with unilateral breast cancer showed that ipsilateral breast cancer was more common before age 45 and contralateral thereafter. The data suggest a possible explanation of the higher incidence of left-breast cancer in American women. A higher percentage of left-handed women developed breast cancer before age 45, but the over-all incidence of unilateral breast cancer was not greater in left-handed women than in right-handed or ambihanded subjects.

Generosity: a psychological and interpersonal motivational factor of therapeutic relevance

This paper examines the role of generosity in analysis. Generosity represents a complex constellation of cognitions and affects that is antithetical to those states of super-ego harshness that characterize many forms of human psychopathology. In development, generosity is evoked by idealization, and a dynamic axis of idealization-generosity promotes relational proximity between the child and its caretakers, and eventually fosters separation and individuation. Generosity is highly sensitive to adverse conditions, and requires environmental conditions that are conducive to psychosomatic well-being. The imaginal basis of generosity is rooted in the myth of the 'hero and the return', which is the mythic foundation of the analyst's role as psychopomp. It is argued that the generosity of the analyst is a cardinal therapeutic factor in treatment.
