Desire for control, locus of control, and proneness to depression

Two personality constructs, desire for control and locus of control, were related to depression among college students. Measures of levels of depression, desire for control, and locus of control were taken from subjects. Approximately six months later 71% of these subjects returned a questionnaire concerning their experiences with depression during that six-month period. It was found that locus of control scores, particularly the extent to which subjects perceived that their lives were controlled by chance, were significantly related to the depression levels. It was also found that high desire for control subjects who held external perceptions of control were most likely to seek nonprofessional help for depression. In addition, high desire for control subjects who perceived their lives as generally controlled by chance were most likely to have suicidal thoughts. The results are interpreted in terms of a general style that may promote a proneness to depression for certain individuals.     

Conflict, consciousness, and control

To what degree is executive conflict resolution dependent on conflict awareness? A recent study by Dehaene et al. compared neural responses to conflict elicited through either visible or subliminal primes. Despite behavioral conflict effects for both prime types, neural activity in a control network including the anterior cingulate cortex (ACC) was present only for visible primes. Along with other recent results, these findings have important implications for theories on the relationship between ACC, consciousness, and cognitive control.     

Self-evaluation,self-reinforcement,and locus of control

Two verbal recognition memory tests were administered to 24 internals and 24 externals. Subjects were required to self-evaluate (SE) their responses on the first test and both SE and self-reinforce (SR) on the second. There were no internal-external differences in performance accuracy on either task, but internals gave themselves consistently higher self-evaluations, administered more positive SR and less negative SR. There were no differences in the criteria used by the two groups for SR. SR differences appeared to be a function of the differential SE. It was suggested that external locus of control could be viewed as a self-regulation deficit. Externals are hypothesized to be unable to evaluate their own behavior adequately in the absence of external input and therefore do not make effective use of self-reinforcement. Discussion also made reference to the process of self-regulation.     

Keeping the illusion of control under control: Ceilings, floors, and imperfect calibration

Prior research has claimed that people exaggerate probabilities of success by overestimating personal control in situations that are heavily or completely chance-determined. We examine whether such overestimation of control persists in situations where people do have control. Our results suggest a simple model that accounts for prior findings on illusory control as well as for situations where actual control is high: People make imperfect estimates of their level of control. By focusing on situations marked by low control, prior research has created the illusion that people generally overestimate their level of control. Across three studies, we show that when they have a great deal of control, people under-estimate it. Implications for research on perceived control and co-variation assessment are discussed.     

Temperament, anxiety, and attentional control

To regulate attention has been a significant component of individual differences in temperament, and other research supported a relation between measures of attentional control and anxiety, i.e., high scores on trait anxiety were correlated with inability to regulate attention in response to the environment, so enhanced attentional control may interact with dimensions of temperament to modify the effects of generalized anxiety. To test this hypothesis, 69 undergraduates completed the Revised Dimensions of Temperament Survey, the Burns Anxiety Scale, and the Derryberry and Reed measure of Attentional Control. Analysis suggested attentional control may be a significant factor in modifying reported anxiety. Further research is warranted, given the present small sample tested with numerous measures.     

Correspondence training, prior verbal training, and control of nonverbal behavior via control of verbal behavior

The role of prior verbal training in correspondence training and later verbal control of nonverbal behavior was examined in two groups of Head Start children. One group received correspondence training without prior verbal training, the other with. Essentially no differences were found between the two sequences; thus it seems appropriate to consider the content phases (reinforcement contingent on target verbalization alone) of previous research as control procedures and not a necessary precursor to correspondence training.     

Umwelt,food, and the limits of control

This paper draws on the work of the early 20th century ethologist Jakob von Uexküll to formulate a notion of food as a process of bodies becoming other bodies. I begin by situating my argument in relation to two strands of critical food research – feminist-inspired work on food and embodiment, and posthumanist approaches that focus on non-humans as mediators of food assemblages. I then discuss Uexküll's work, focusing on three key concepts: umwelt, “the island of the senses” that envelops each being; subjectivity as an intra- and intercorporeal phenomenon; and the variation among umwelten available to humans. These ideas, I contend, illustrate the inherently political nature of ‘food,’ which in turn calls for a realignment of food ethics and critical food scholarship. To illustrate this contention, I draw on my research with the Oklahoma Food Cooperative, considering this socio-ecological experiment as an effort to create a food system in better accord with the affective imperatives (or umwelten) of its constituent components. Throughout the paper, I develop the argument that food systems will always present limits to control by even those actors who seem to enjoy hegemonic positions. Uexküll's work helps us understand these limits in a way that allows critical analysis of dominant food systems and the alternatives proliferating in response to them, but does not prematurely foreclose the actual and virtual possibilities contained in the present heterogeneity of foodways.     

Anxiety, perception, and control of heart rate

8 women and 8 men took Cattell's IPAT-anxiety questionnaire and later McFarland's test of ability to perceive heart activity. The second test involved subjects' tracking their own heart rates, then they enrolled in an EKG biofeedback session to evaluate ability to increase and decrease heart rate from subjects' resting baselines. At the end of the session each subject completed Blanchard, et al.'s questionnaire to specify the cognitive strategies used for heart-rate control. Heart rate, abdominal respiration rate, respiration amplitude, EEG percent power in theta, alpha, and beta bands were evaluated. Success of heart-rate decrease seemed to depend mainly on activity levels: the subjects who achieved high scores on the activity test decreased heart rate significantly better than did low scorers. The relationship between scores for perception of heart and increases in heart rate was nonsignificant: increased heart-rate seemed to depend on differences in respiration between the rest and periods of increase. The significant, negative correlation between trait anxiety and perceptions of heart activity suggested that anxiety affected subjects' ability to perceive heart rate. The theta EEG power of the right hemisphere was significantly higher in subjects scoring high than for those low in perception of heart activity. During heart-rate increase tasks subjects mainly reported use of 'arousal responses,' similarly during heart-rate decrease tasks they reported use of relaxation responses.     

Levels, hierarchies, and the locus of control

The Bartlett--Craik view of human performance is restated; and particularly that it is organised at different levels. On that view, the lower levels are controlled by the upper but capable of functioning independently. Modern views of memory, language, and problem-solving are compared with this doctrine, and found to embody some of its virtues but not all. Fresh experiments are described, in which people take decisions about the running of a transportation system. The simplest control mechanism which will model their behaviour is a two-level adaptive controller.     

The interactive effects of listwide control, item-based control, and working memory capacity on Stroop performance

Hypothesized top-down and bottom-up mechanisms of control within conflict-rich environments were examined by presenting participants with a Stroop task in which specific words were usually presented in either congruent or incongruent colors. Incongruent colors were either frequently (high contingency) or infrequently (low contingency) paired with the word. These items were embedded within lists consisting of either 100% congruent or 100% incongruent filler items to create mostly congruent or mostly incongruent lists. Results indicated a significant item-specific congruency effect, which was largest for high contingency responses and within mostly congruent lists. In addition, a significant listwide congruency effect was obtained, and this interacted with working memory capacity (WMC). There were larger listwide congruency effects for low WMC individuals. Finally, the pattern of Stroop interference across lists for low WMC individuals was dependent upon the congruency of the preceding trial. These results support multiple forms of cognitive control, as well as contingency learning, as mechanisms underlying proportion congruence effects in Stroop and other conflict tasks. These findings are interpreted within Braver, Gray, and Burgess's (2007) dual mechanisms of control theory.     

Desired control,felt control,and dental pain: Recent findings and remaining issues

This paper reviews a series of studies examining how desire for control among dental patients affects their reaction to dental treatment. This research (across eight samples) indicates that low perceived control is associated with heightened stressful responding before and during dental treatment only among patients reporting high desire for control Thus, the impact of low perceived control appears to be moderated by desire for control. An additional finding is that manipulations of control (e.g., providing information, stress inoculation training) primarily impact patients reporting both a high desire for control (during treatment) and low initial perceived control. These data suggest that consideration of patients' desire for control in addition to their perceived control increases our ability to predict their level of dental stress. Additionally, these data provide initial support for the view that the discrepancy between high desire for control and low perceived control play a causal role in patient's perceptions of dental pain and fear.This research was supported by grant USPHS-NIH 5 RO1 DEO 9419-02 (H. L. and R. B. coprincipal investigators) and by BRSG/College of Dentistry seed money.     

Agreeableness,conscientiousness, and effortful control processes

Effortful control (EC) is believed to be a superordinate, temperament system that is associated with early-appearing individual differences in self-regulation. It has been suggested that EC indexes the common developmental process underlying Agreeableness and Conscientiousness. Theory suggests this association, but little empirical evidence has linked personality to actual self-regulatory behaviors. This study examined personality and cognitive assessments associated with impairments in self-regulation. College students (N=113) gave self-reports on the five dimensions of personality. They also completed the Stroop test, Wisconsin Card Sorting Task (WCST), and a verbal fluency test. Agreeableness predicted Stroop reaction times. Both Agreeableness and Conscientiousness predicted WCST measures. Conscientiousness predicted verbal fluency for men. Results were discussed in terms of EC being a common developmental substrate of Agreeableness and Conscientiousness.
