Experiential Avoidance as an Emotion Regulatory Function: An Empirical Analysis of Experiential Avoidance in Relation to Behavioral Avoidance,Cognitive Reappraisal,and Response Suppression

The purpose of the present study was to empirically test the suggestion that experiential avoidance in an emotion regulation context is best understood as an emotion regulatory function of topographically distinct strategies. To do this we examined whether a measure of experiential avoidance could statistically account for the effects of emotion regulation strategies intervening at different points of the emotion-generative process as conceptualized by Gross' (1998) process model of emotion regulation. The strategies under examination were behavioral avoidance, cognitive reappraisal, and response suppression. The specific hypotheses to be tested were (1) that behavioral avoidance, cognitive reappraisal, and response suppression would statistically mediate the differences in measures of psychological well-being between a clinical and nonclinical sample, but that (2) these indirect effects would be reduced to nonsignificant levels when controlling for differences in experiential avoidance. The results provide clear support for the first hypothesis with regard to all the studied strategies. In contrast to the second hypothesis, the results showed the predicted outcome pattern only for the response-focused strategy “response suppression” and not for cognitive reappraisal or behavioral avoidance. The results are interpreted and discussed in relation to theories on experiential avoidance and emotion regulation.     

An Attempt to Predict Change in Mood in Response to Velten-Like Mood Induction Procedures

College student subjects were rated high or low in cognitive and behavioral depression proneness, based on their scores on a screening battery that included the Automatic Thoughts Questionnaire (Hollon & Kendall, 1980), the Dysfunctional Attitude Scale (Weissman, 1979), the Intemality-Extemality Scale (Rotter, 1966), the Pleasant Events Schedule and the Unpleasant Events Schedule (Lewinsohn & Amenson, 1978). The students were subsequently exposed to one of two different Velten-like depressive mood inductions, one based on Beck's (1974) model of depression, and the other based on Lewinsohn's (1974) model. We hypothesized that subjects who scored higher on the cognitive measures would tend to become more depressed when exposed to the Beck statements and that those who scored higher on the behavioral measures would tend to become more depressed when exposed to the Lewinsohn statements. The hypothesis was not supported. Instead, pre-existing cognitively or behaviorally defined depression proneness appeared to be unrelated to subjects' susceptibility to one or the other model of depression as defined by the two mood inductions. However, the inductions themselves were found to produce a significant lowering of mood, and both inductions were equally effective in lowering mood.     

Experiential Avoidance as a Moderator of the Relationship Between Anxiety Sensitivity and Perceived Stress

Given the significant deleterious effects of stress on psychological and physical well-being, the present two-part study sought to clarify relations among putative vulnerability factors (i.e., anxiety sensitivity, experiential avoidance) for perceived stress. Relations among anxiety sensitivity, experiential avoidance, and perceived stress were examined using a large college student sample (N = 400) in Study 1 and were replicated using a large community sample (N = 838) in Study 2. As predicted, experiential avoidance moderated the relationship between anxiety sensitivity and perceived stress. Contrary to expectations, simple effects in both studies revealed that anxiety sensitivity shared a significant positive association with perceived stress at low, but not high, levels of experiential avoidance. The moderating role of experiential avoidance was found to be robust to the effects of general distress. Moreover, anxiety sensitivity and experiential avoidance evidenced a differential pattern of relations with perceived stress than was evidenced with related negative affective states (i.e., anxiety and depression). The present results suggest that experiential avoidance appears to be a vulnerability factor of particular importance for understanding the phenomenology of perceived stress. Conceptual and clinical implications are discussed.     

The contribution of music vs instructions in the Musical Mood Induction Procedure

The relative contribution of the instructions and the music to the effects of the Musical Mood Induction Procedure (MMIP) were investigated. Using an experimental procedure which minimised covert experimenter bias, subjects performed under both elation and depression mood inductions in one of four conditions: music present or absent by mood change instructions present or absent, using a crossover design. Results indicated that instructions were both necessary and sufficient to produce change on mood sensitive measures. Mood change effects were reduced by controlling for the effect of subjects who responded so as not to ‘louse-up’ the experiment. The MMIP seems to be much less musical than the name implies. Further research is needed to determine which aspects of the instructions contribute most to the changes on mood sensitive measures.     

The Velten Mood Induction Procedure and cognitive manipulation: Our response to Clark (1985)

Clark (1985) makes several thoughtful points about studies using the Veiten Mood Induction Procedure (VMIP; Veiten, 1968). We still disagree with his position, and interpret the evidence as supporting that the VMIP is a cognitive manipulation. Furthermore, our cognitive priming position may offer a more parsimonious and coherent explanation of the VMIP findings on mood induction, memory and other mood-linked behaviors.     

Day-to-Day Variability in Empathy as a Function of Daily Events and Mood

Despite broad agreement that understanding a personality construct requires integrating trait and state levels of analysis, few studies have explicitly attempted such an integration. The present study did this by examining the relationships between trait and state measures of empathy. State measures were taken daily, with a focus on the day level (within-person) covariation between empathy and daily mood and events. Twice a week for up to 10 weeks, 103 participants provided measures of their daily empathy and mood (NA and PA) and described the events that occurred each day. Multilevel random coefficient modeling analyses found that daily empathy covaried positively with the impact of daily positive and negative social events and with daily positive and negative affect. Empathy did not covary with achievement-related events. Analyses that simultaneously included empathy, mood, and events suggested that daily NA mediated relationships between daily empathy and daily negative social events. Although mean daily empathy was positively related to trait empathy, trait empathy did not moderate relationships between daily empathy and events nor between daily empathy and mood. Moreover, daily empathy did not covary with daily depressogenic thinking, need for cognition, nor self-esteem, suggesting that empathy is distinct from these constructs. Possible mechanisms linking social events and empathy, such as emotional contagion, are discussed.     

Programming Time as a Function of Response Duration

Reaction time was longer prior to longer-lasting pressing responses for low probability, unanticipated movements. By contrast, reaction time was independent of response duration for high probability, anticipated movements. This replicates and extends previous findings for choice and simple reaction time in the “dit-dah” paradigm. The present results (unanticipated responses) cannot be given a selective anticipation interpretation because the comparison is between responses which are never anticipated. The previous paradigm was open to an alternative interpretation in which selective anticipation of dit rather than dah could have produced the differences in choice reaction time. Confirmation of the finding that variations in required response duration lead to differences in reaction time supports the view that the underlying parameter of “complexity” in the “memory drum theory” may be response duration.     

The Contributing Role of Negative Affectivity and Experiential Avoidance to Increased Cardiovascular Risk

Depression and anxiety are independent risk factors for the onset of cardiovascular disease, independent of classical risk factors, such as smoking, obesity, or hypertension. The present paper argues that the tendency to avoid difficult thoughts and feelings helps explain this relationship. There is a strong positive relationship between experiential avoidance and negative affectivity. Experiential avoidance is also related to several health behaviors recognized for increasing cardiovascular risk and may help functionally explain why individuals engage in problematic behaviors, such as smoking, drinking, and binge eating. Treatments that undermine experiential avoidance could be useful psychosocial approaches to cardiovascular risk reduction.     

Development of a measure of experiential avoidance: the Multidimensional Experiential Avoidance Questionnaire

Experiential avoidance (EA) has been conceptualized as the tendency to avoid negative internal experiences and is an important concept in numerous conceptualizations of psychopathology as well as theories of psychotherapy. Existing measures of EA have either been narrowly defined or demonstrated unsatisfactory internal consistency and/or evidence of poor discriminant validity vis-à-vis neuroticism. To help address these problems, we developed a reliable self-report questionnaire assessing a broad range of EA content that was distinguishable from higher order personality traits. An initial pool of 170 items was administered to a sample of undergraduates (N = 312) to help evaluate individual items and establish a structure via exploratory factor analyses. A revised set of items was then administered to another sample of undergraduates (N = 314) and a sample of psychiatric outpatients (N = 201). A 2nd round of item evaluation was performed, resulting in a final 62-item measure consisting of 6 subscales. Cross-validation data were gathered in 3 new, independent samples (students, N = 363; patients, N = 265; community adults, N = 215). The resulting measure (the Multidimensional Experiential Avoidance Questionnaire, or MEAQ) exhibited good internal consistency, was substantially associated with other measures of avoidance, and demonstrated greater discrimination vis-à-vis neuroticism relative to preexisting measures of EA. Furthermore, the MEAQ was broadly associated with psychopathology and quality of life, even after controlling for the effects of neuroticism.     

Avoidance conditioning as a function of appetitive stimulus pretraining: Response and stimulus transfer effects

Pretrained appetitive discriminative stimuli were used as warning signals in subsequent avoidance learning. In Expt 1 identical responses were required in pretraining and in avoidance learning. An appetitive S+ facilitated avoidance learning in rats in comparison to S? or a stimulus previously uncorrelated with food. In Expt 2, the type of response in pretraining and in avoidance learning was varied. Groups with homogeneous responses in the two situations replicated Expt 1 results, whereas groups with different responses in pretraining and avoidance learning failed to show an advantage when S+ served as warning; in the heterogeneous response groups, S? was as effective as S+. Inhibitory factors in the heterogeneous groups were discussed as an explanation for these results.     

Personality as a Prospective Vulnerability to Dysphoric Symptoms Among College Students: Proposed Mechanisms

Personality and psychopathology have long been associated; however, the mechanisms that account for this link are not well understood. Stress generation and cognitive vulnerability are examined as potential mechanisms to explain the association between negative emotionality and dysphoria. To evaluate these mechanisms, college students completed measures of personality, dysfunctional attitudes, negative cognitive style, dysphoric symptoms, and negative events. Two years later the same students reported on the occurrence of negative events and levels of dysphoric symptoms that they had experienced over the 2-year follow-up period. Consistent with hypotheses, negative emotionality predicted prospective increases in dysphoric symptoms and the generation of more stressors over time. Both dysfunctional attitudes and negative cognitive style interacted with these additional stressors to predict prospective elevations in dysphoria, and these cognitive vulnerability–stress components partially mediated the association between negative emotionality and future elevations of dysphoric symptoms.

Motor Performance and Response Consistency as a Function of Age

The specificity versus generality of motor performance and motor response consistency was investigated as a function of age. 120 Ss, 30 each at age 7, 11, 15, and 19 yr., were given 120 practice trials (60 trials per session with 24 hr interpolated between sessions) on both simple and choice RT tasks. For motor performance the reliability of individual differences was high in both tasks at all ages, while the amount of generality was moderately high in the two younger groups but diminished with age. The reliability coefficients for motor response consistency were low for both tasks but, with two exceptions, statistically significant. There was no evidence for generality in motor response consistency at any age.     

Response Timing Accuracy as a Function of Movement Velocity and Distance

In two experiments, patterns of response error during a timing accuracy task were investigated. In Experiment 1, these patterns were examined across a full range of movement velocities, which provided a test of the hypothesis that as movement velocity increases, constant error (CE) shifts from a negative to a positive response bias, with the zero CE point occurring at approximately 50% of maximum movement velocity (Hancock & Newell, 1985). Additionally, by examining variable error (VE), timing error variability patterns over a full range of movement velocities were established. Subjects (N = 6) performed a series of forearm flexion movements requiring 19 different movement velocities. Results corroborated previous observations that variability of timing error primarily decreased as movement velocity increased from 6 to 42% of maximum velocity. Additionally, CE data across the velocity spectrum did not support the proposed timing error function. In Experiment 2, the effect(s) of responding at 3 movement distances with 6 movement velocities on response timing error were investigated. VE was significantly lower for the 3 high-velocity movements than for the 3 low-velocity movements. Additionally, when MT was mathematically factored out, VE was less at the long movement distance than at the short distance. As in Experiment 1, CE was unaffected by distance or velocity effects and the predicted CE timing error function was not evident.

Age Differences in the Distractor-Ratio Effect as a Function of Contrast Level

ABSTRACT

Latencies (RT) and eye movement measures were used to examine the effects of age and contrast on the distractor-ratio effect (DRE) in visual search. Younger and older adults performed a contrast × orientation conjunction search task where the ratios of white to black distractors and luminance contrast levels were varied. The distractor-ratio manipulation had similar effects for older and younger adults on both RT and the number of fixations required to find the target. Both measures were largely independent of distractor ratio on target-present trials, while both RTs and the fixation number increased with the number of items sharing the target's contrast polarity on target-absent trials. A more detailed analysis of eye movements suggested that younger adults were a bit more adept at attending to the smaller set of distractors, which presumably facilitated both overt and covert search. Generalized slowing can account for the age differences in RT, but the fixation number data speak to another mechanism, perhaps increased cautiousness on the part of the elderly when signal strength is low.     

Variation in Coordination of a Discrete Multiarticular Action as a Function of Skill Level

The authors investigated coordination modes that emerged as a function of the interaction between skill level and task constraints in a multiarticular kicking action. Five skilled, 5 intermediate, and 5 novice participants attempted to satisfy specific height and accuracy constraints in kicking a ball over a barrier. Skilled and intermediate groups demonstrated a functional coordination mode involving less joint involvement at the proximal joints and greater joint involvement at distal joints, mimicking a chip-like action in soccer. Conversely, the novice group tended to produce larger ranges of motion throughout the kicking limb in a driving-like kicking action. Key differences were also found for task outcome scores, joint angle-angle relations, and ball-trajectory plots between the skilled and intermediate groups and the novice group. Findings from this study demonstrated that joint involvement during this discrete multiarticular action is a function of skill level and task constraints rather than a consequence of a global freezing-freeing strategy suggested in some previous research. The authors also highlight the merit of using a model of the acquisition of coordination in examining how coordination modes for multiarticular actions differ as a function of skill.     

Mood Propensity as a Constituent of Happiness: A Rejoinder to Hill

In an earlier paper I defended an emotional state theory of happiness. In a basic form, emotional state theories identify happiness with a person’s moods and emotions. To this formulation I added a second component, “mood propensity”: roughly, an individual’s disposition to experience moods, which can vary with the circumstances. Scott Hill argues that this view is vulnerable to a serious counterexample and that my intuitive arguments for it are unconvincing. This paper extends my earlier defense of mood propensity as an aspect of happiness, in the process replying to Hill’s objections. I argue that the intuitive considerations favoring my view are not weakened by the points Hill raises. Moreover, the inclusion of dispositional elements in a theory of happiness is actually quite common, and there are good substantive, and not just intuitive, reasons for incorporating mood propensity in the account. In particular, it seems to be required by the guiding conception of happiness as a matter of a person’s overall emotional condition.     

Avoidance of risk as a determinant of cooperation

Pairs of subjects could either cooperate or respond on a lower paying individual task. Whenever both subjects chose to cooperate, either subject could make a response that took $1.00 of the other's earnings. In Exp. I, a stimulus signalled when a “take” response had been made. Either subject could avoid the loss by switching to the individual task within 5 sec after the stimulus appeared. Rates of cooperation were high when losses could be avoided but decreased again when the avoidance condition was removed. In Exp. II, a response prevented “takes” from occurring for a specified time interval after the response. This procedure also maintained cooperation. When each avoidance response subtracted from earnings, both avoidance responding and cooperation were eliminated.
