Categorical flexibility in children: Distinguishing response flexibility from conceptual flexibility; the protracted development of taxonomic representations

This research explored the development of children's use of multiple conceptual organizations (thematic, taxonomic) in sorting sets of pictures. Experiment 1 revealed that between 5 and 9 years, two forms of categorical flexibility can be distinguished: response and conceptual flexibility. It appeared that children's multiple sorts do not necessarily reflect the use of different conceptual organizations. Such a lag was mainly due to a difficulty in accessing taxonomic representations, specifically in the younger age groups. Therefore, Experiment 2 investigated the development of taxonomic representations using an original approach requiring participants to decide whether new items could be included into an existing taxonomic sort. This approach showed that taxonomic representations were only gradually differentiated from thematic and perceptual ones over the 5 to 10 years period. The discussion raises new hypotheses about the interaction between developing executive control (specifically, increasing resistance to interference of irrelevant information) and increasing conceptual knowledge in accounting for the development of conceptual flexibility.     

Cognitive flexibility and response inhibition in patients with Obsessive-Compulsive Disorder and Generalized Anxiety Disorder

Background/ObjectiveThe main aim of this study was to analyze differences in inhibition and cognitive flexibility, taking into account some variables that may influence results (non verbal reasoning, depression, anxiety, intolerance of uncertainty, comorbidity, medication consumption).MethodThe participants were 95 adults aged 17-61 years old (M = 33.48, SD = 11.13), primary (most severe) Generalized Anxiety Disorder or Obsessive-Compulsive Disorder and a healthy control group. Neuropsychological neasures were completed using computerized Wisconsin Card Sorting Test, Stroop Color Word Test and Go/NoGo Task.ResultsClinical groups presented worse results in cognitive flexibility to the control group. The obsessive-compulsive group showed worse scores in flexibility than the generalized anxiety group, once non-verbal reasoning and tolerance to uncertainty were controlled. Comorbidity and medication use did not affect results in the obsessive compulsive group but did however influence the generalized anxiety group.ConclusionsCognitive flexibility could be included treatment in the treatment of obsessive-compulsive disorder and generalized anxiety disorder.     

Cognitive flexibility in preschoolers: the role of representation activation and maintenance

Preschoolers' lack of cognitive flexibility has often been attributed to perseverative processing. This study investigates alternative potential sources of difficulty such as deficits in activating previously ignored information and in maintaining currently relevant information. In Experiment 1, a new task tapping attentional switching was designed to isolate the difficulty of overriding an initial representation, that is, perseverative processing ('Perseveration' version), and the difficulty of activating a previously ignored representation, that is, activation deficit ('Activation-deficit' version). Three-year-olds' performance suggested that inflexibility may primarily stem from an activation deficit. Control experiments confirmed that the difficulty of the 'Activation-deficit' version could not be attributed to the effect of attraction to novelty. In Experiment 2, 'distraction' errors, alleged to reflect a failure to maintain a relevant representation, and 'perseverative' errors were distinguished. The results highlighted the important role of representation maintenance in flexibility. The present study indicates that preschoolers' lack of cognitive flexibility is multi-determined and prompts us to reconsider the role of perseveration.     

Cognitive processes underlying coping flexibility: differentiation and integration

This study investigates how individuals formulate flexible coping strategies across situations by proposing differentiation and integration as two stress-appraisal processes. Results showed that participants who coped more flexibly adopted the dimensions of controllability and impact in differentiating among different stressful situations. They also deployed an integrated strategy: the deployment of more monitoring in situations perceived as controllable but less of this strategy in situations perceived as uncontrollable. Participants who coped less flexibly did not adopt any given dimensions and tended to use more monitoring regardless of situational characteristics. These results suggest that individuals with different extents of coping flexibility differ in the cognitive processes. Individuals who cope more flexibly display a greater extent of differentiation and integration than do those who cope less flexibly. These findings are translated into strategies for stress management workshops.     

Cognitive processes mediating behavioral change.

The present experiment was designed to test the theory that psychological procedures achieve changes in behavior by altering the level and strength of self-efficacy. In this formulation, perceived self-efficacy. In this formulation, perceived self-efficacy influences level of performance by enhancing intensity and persistence of effort. Adult phobics were administered treatments based upon either performance mastery experiences, vicarious experiences., or they received no treatment. Their efficacy expectations and approach behavior toward threats differing on a similarity dimension were measured before and after treatment. In accord with our prediction, the mastery-based treatment produced higher, stronger, and more generalized expectations of personal efficacy than did the treatment relying solely upon vicarious experiences. Results of a microanalysis further confirm the hypothesized relationship between self-efficacy and behavioral change. Self-efficacy was a uniformly accurate predictor of performance on tasks of varying difficulty with different threats regardless of whether the changes in self-efficacy were produced through enactive mastery or by vicarious experience alone.     

Cognitive tuning sets: Anticipating the consequences of communication

This paper reviews the literature on cognitive tuning sets: the expectations of having to transmit or receive information. It is shown that having to transmit information leads to a unified and distorted summary being transmitted, a reluctance to receive additional information, a rejection of inconsistent information, and a shaping of the material to accommodate the anticipated audience. As well, the opinions of the transmitters become polarized. It is argued that the receiver condition is probably not the correct control group to use since the outcome depends on the uncontrolled perceived goals. It is suggested that future research should probably treat the multiple effects of cognitive tuning sets separately. An integrated explanation is given in terms of anticipating the consequences of communication. This work was supported by a grant from the Australian Research Grants Scheme.

Cognitive complexity in response to traumatic experiences

Two studies examined how personality motives influence the perception of traumatic events in memory and how such perception may be linked to psychological distress. Participants completed implicit and explicit measures of agentic and communal motives. In Study 1, participants living in New York City at the time of the terrorist attacks wrote their thoughts and feelings about the events of September 11th. In Study 2, participants wrote about a personally traumatic experience. In both studies, they also completed questionnaires on psychological symptoms and stress-related growth. The memories were then scored for differentiation and integration. Agentic motives correlated with differentiated perceptions and differentiation was linked to dissociative symptoms in Study 2. Communal motives related to integrated perceptions, and integration related to stress-related growth in both studies. Findings suggest that motives play a significant role in the perception of traumatic and difficult experiences and that these perceptions may be differentially linked to psychological impact.     

Cognitive and motivational processes underlying coping flexibility: a dual-process model

Discriminative facility was proposed as a cognitive process and need for closure was proposed as a motivational process underlying coping flexibility. The dual-process model posits that need for closure influences discriminative facility, which in turn modifies coping flexibility and psychological adjustment. In Study 1, results of structural equation modeling provided support for the dual-process model. This model was further examined using experimental methods (Study 2) and a prospective design (Study 3). Consistent with the dual-process model, results from all 3 studies showed that participants who were more motivated to seek alternative coping strategies tended to encode stressful situations in a more differentiated way. These individuals used a greater variety of strategies to fit different situational demands and were better adjusted.     

Openness to experience, identity flexibility, and life change in adults

The personality trait of openness to experience was used to predict identity flexibility, the tendency of adults to evaluate alternative identity commitments in the area of family and work. Openness to experience was also used as an independent variable to predict the occurrence of actual life change 12 months after identity flexibility was ascertained. A sample of 57 adults (34 women and 23 men) ranging in age from 24 to 61 (M = 41 years) was tested twice over the 12-month period. Age and openness to experience significantly predicted identity flexibility, whereas only years of education predicted life change. Identity flexibility was significantly related to life change. It was concluded that both personality and perceived and actual social resources are predictors of flexibility and life change in adulthood.     

Timing of dietary change in response to a telephone counseling intervention: evidence from the WHEL study

OBJECTIVE: Little is known about temporal patterns of diet change within interventions, nor about predictors of early and sustained successful change. Social-cognitive theory asserts that early successes in achieving behavior change increase self-efficacy, leading to longer-term success. DESIGN: The authors conducted exploratory cluster analyses using dietary data from the first month of the telephone counseling intervention of the Women's Healthy Eating and Living (WHEL) Study. MAIN OUTCOME MEASURE: Change in dietary pattern at three early intervention timepoints. RESULTS: Three clusters were identified: Cluster 1 (25%) was close to meeting study goals at baseline, but still made major changes; Cluster 2 (49%) and Cluster 3 (26%) were not achieving study goals at baseline, but Cluster 2 made substantial immediate changes, while Cluster 3 changed their diet more gradually. Baseline demographic and behavioral variables were associated with cluster membership; however, the strongest predictors of cluster were self-efficacy, motivation, and approaches to study goals. Cluster membership predicted dietary pattern at 12 months. CONCLUSION: These data suggest that a one-on-one telephone counseling intervention that is intensive in the early weeks may maximize the level of change achieved in a study.     

Cognitive change processes in psychotherapy

Several types of cognitive-behavioral therapy are now practiced that use different sets of theoretical concepts and propose different kinds of change mechanisms. None, however, is directly grounded in experimental research in cognitive and social psychology, and few address basic issues such as the relevance of conscious versus nonconscious cognitive processes and the validity of the self-report data on which therapy depends. Put forward in this article is a model that describes the conscious and nonconscious processing of emotional stimuli and distinguishes between knowledge that is verbally accessible and knowledge that can only be recovered by exposure to situational cues. Also proposed are three mechanisms of cognitive change that involve altering verbally accessible knowledge, the accessibility of nonconscious situational memories, and self-regulatory strategies. These mechanisms are related to the current practices of behavioral and cognitive-behavioral therapists.     

Expert judgments of hypnosis from subjective state reports.

Suggestibility was assessed in 60 college students after a traditional hypnotic induction, an alert induction, progressive relaxation training, or instruction in goal-directed imagery. Responsiveness to suggestion did not differ between groups. Subjects also generated open-ended reports of their states of awareness and of their experience of 3 hypnotic suggestions. A sample of these reports from 24 moderately to highly suggestible subjects were evaluated by 18 experts in the field of hypnosis. Expert ratings of subjects' open-ended reports indicated that (a) traditional hypnotic inductions produce a state of consciousness that is indistinguishable from nonhypnotic relaxation training, (b) the subjective experience of hypnotic suggestions after imagination training is indistinguishable from that after hypnotic inductions, and (c) suggestibility is unrelated to state of consciousness as assessed by experts.     

Cognitive performance inconsistency: intraindividual change and variability

Although many studies have examined inconsistency of cognitive performance, few have examined how inconsistency changes over time. 91 older adults (age 52 to 79) were tested weekly for 36 consecutive weeks on a series of multitrial memory speed (i.e., letter recognition) tasks. A number of multivariate techniques were used to examine how individuals' level of inconsistency changed across weeks and how this change was related to interindividual differences in age and intelligence. Results indicated that (a) inconsistency of performance is a construct separate from the underlying performance ability (i.e., memory speed); (b) inconsistency reduces exponentially with practice; (c) individuals with higher scores on tests of fluid general intelligence (G-sub(f)) reached lower asymptotic levels of inconsistency compared to lower scorers; and (d) after controlling for the systematic effects of practice, variability in inconsistency from week-to-week was more pronounced for individuals with lower G-sub(f) scores compared to individuals with higher scores.
