Variable-interval schedules of timeout from avoidance

Rats were trained on concurrent schedules in which pressing one lever postponed shock and pressing the other occasionally produced a 2-min timeout during which the shock-postponement schedule was suspended and its correlated stimuli were removed. Throughout, the shock-postponement schedule maintained proficient levels of avoidance. Nevertheless, in Experiment 1 responding on the timeout lever was established rapidly, was maintained at stable levels on variable-interval schedules, was extinguished by withholding timeout, was reestablished when timeout was reintroduced, and was brought under discriminative control with a multiple variable-interval extinction schedule of timeout. These results are in contrast with Verhave's (1962) conclusion that timeout is an ineffective reinforcer when presented to rats on intermittent schedules. In Experiment 2 the consequence of responding on the timeout lever was altered so that the shock-postponement schedule remained in effect even though the stimulus conditions associated with timeout were produced for 2 min. Responding extinguished, indicating that suspension of the shock-postponement schedule, not stimulus change, was the source of reinforcement. By establishing the reinforcing efficacy of timeout with standard variable-interval schedules, these experiments illustrate a procedure for studying negative reinforcement in the same way as positive reinforcement.     

Typical coping patterns: A person-centered approach to coping

Applying the person-oriented approach to coping can provide a unique perspective by revealing typical latent patterns. The study examined typical latent patterns shown by task-, emotion- and avoidance-oriented trait-based coping styles. We performed secondary analyses with Latent Profile Analysis on our former data and three independent datasets containing coping measures with the CISS-48 scale (Endler & Parker, 1994). Gender differences were also studied. Two basic profiles seem universal: the first is characterized by a high level of task-oriented coping, and the second profile is with moderately high scores on all three coping styles. The finding indicates that two fundamental latent coping profiles exist, which suggests a within-subject comparison in practice instead of investigating the absolute value of coping styles. Comparing data before and after 2020, COVID-19 does not seem to affect these profiles. The person-centered approach provides a possibility for the integration of coping-related findings.     

Personality traits,coping strategies and quality of life in patients of hepatitis C

IntroductionIn recent decades, hepatitis has become a community health issue. A severe, asymptomatic and unobserved acute disease could be resulted by HCV and it could be treated completely in few cases or could result in chronic hepatitis.ObjectiveThe current research investigated the relationship among personality traits, coping strategies and quality of life in patients of hepatitis C in Pakistan.MethodTotal 102 patients of HCV were selected from government, semi-government and private hospitals. Mental Health Screening Questionnaire (Mirza & Kausar, 2008) was used to screen the patients. The Urdu versions of Big Five Inventory (John & Srivastava, 1999), Coping Strategies Questionnaire (Kausar & Munir, 2004) and Quality of Life-BREF (1997) were used to measure the study variables.ResultsThe results showed that extraversion had positive relationship with the subscales of quality of life except physical health. Conscientiousness had positive relationship with physical and psychological health. Neuroticism had negative relationship with all the domains of quality of life. Openness to experience had positive relationship with psychological health and environment. religious coping and conscientiousness positively predicted physical health, whereas, agreeableness was the negative predictor of physical health. Psychological health and social relationships were positively predicted by active focused coping, whereas, neuroticism negatively predicted psychological health.ConclusionThe results of present research indicated significant contribution of personality traits and coping strategies in maintaining quality of life of HCV patients. The clinical implications to improve quality of life of HCV patients are discussed in light of results.     

Examining the roles of experiential avoidance and cognitive fusion on the effects from mindfulness to athlete burnout: A longitudinal study

ObjectivesAthlete burnout is a maladaptive outcome that is potentially detrimental for performance and wellbeing. Cross-sectional evidence suggests that mindfulness might be associated with athlete burnout via experiential avoidance and cognitive fusion. In the current study, we extend knowledge of these hypothesized mediational pathways using a longitudinal design.MethodsData was collected at three occasions with a three-month interval. A final sample of 280 elite Chinese athletes aged 15–32 years (M_age = 19.13; SD = 2.92; Female = 130) reported their mindfulness at Time 1, experiential avoidance and cognitive fusion at Time 2, and athlete burnout at Time 3. Structural equation modelling was adopted to examine the mediating roles of experiential avoidance and cognitive fusion on the effects from mindfulness to athlete burnout.ResultsWe found statistically meaningful directs effects from mindfulness (Time 1) to experiential avoidance and cognitive fusion (Time 2), which in turn influenced athlete burnout (Time 3). However, the direct effect from mindfulness at Time 1 to athlete burnout at Time 3 was non-significant. The indirect effects of experiential avoidance and cognitive fusion on the effects from mindfulness to athlete burnout were significant, providing longitudinal evidence that these two variables contribute meaningfully to the mindfulness-burnout pathway.ConclusionWith initial evidence for the mediating effects of experiential avoidance and cognitive fusion, future studies could consider using experimental designs to examine the potential changing mechanisms of mindfulness on reducing athlete burnout.     

Resilience and Enhancement in Sport,Exercise, & Training (RESET): A brief self-compassion intervention with NCAA student-athletes

Athletes often believe that self-criticism is necessary to avoid complacency, but this attitude can lead to anxiety and stress. Research shows that self-compassion is an adaptive way to relate to mistakes and challenges. Although there are many benefits of self-compassion, fear that self-compassion harms performance may discourage athletes from adopting this approach. This study developed and tested an online self-compassion intervention for athletes called RESET (Resilience and Enhancement in Sport, Exercise, & Training), adapted from the Mindful Self-Compassion program. Between-group analyses (multilevel modeling; MLM) and within-group analyses (paired t-tests) were used to assess the effectiveness of the intervention on athletes’ ability to respond compassionately to failure, improve well-being, and increase perceived sport performance. Compared to the waitlist control (n = 102, 71% women), the intervention group (n = 148, 90% women) experienced greater increases in self-compassion, decreases in self-criticism and fear of self-compassion, and greater improvements in perceived performance. In general, the intervention was more effective for those who had the most room for growth. Within-group analyses supported the MLM findings while also showing that athletes who participated in the RESET program experienced reduced levels of depression, anxiety, and stress. Program evaluation measures, including participant testimonials, extend the quantitative findings and demonstrate that RESET was engaging, well-liked, and effective.     

No attentional bias for pictoral stimuli in spider-fearful subjects

A number of experiments have shown that (spider) fearful subjects direct their attention to fear-relevant words, even when these words are irrelevant to the completion of a target task (e.g., color naming). The present study examined whether subjects with an intense fear of spiders also display such attentional bias for a fear-relevant pictoral stimulus. Female spider-fearful (n=13) and control subjects (n=13) saw neutral patterns (i.e., horizontal and vertical bars). One pattern served as target for a reaction time, while the other pattern served as nontarget. Targets and nontargets were accompanied by either fear-relevant or neutral pictoral material (i.e., a picture of a spider or a picture of a flower, respectively). The fear-relevant picture did not selectively delibate reaction time performance of spider-fearful subjects. Thus, no evidence was found for an attentional bias for fear-relevant pictoral material in subjects with an intense fear of spiders. Instead, fearful subjects exhibited a general inhibition of performance which became stronger over trials. This suggests that the fear-relevant picture induced a state of anxious arousal or defensive withdrawal that interfered with reaction time performance on both fear-relevant and neutral trials.     

STIMULUS (INSTRUCTIONAL) FADING DURING EXTINCTION OF SELF-INJURIOUS ESCAPE BEHAVIOR

Three individuals with developmental disabilities were exposed to a series of assessment conditions to identify the source of reinforcement for their self-injurious behavior. In each case, self-injury occurred most often in instructional (demand) situations containing a brief time-out from the task contingent on self-injury, indicating that the behavior was an escape response (i.e., maintained by negative reinforcement). Treatment was implemented in a multiple baseline across subjects design and consisted of extinction (prevention of escape) plus instructional fading (initial elimination of instructions followed by their gradual reintroduction). Results showed that the combined treatment produced immediate and large reductions in self-injury that were maintained as the frequency of instructions was increased across sessions to match the original baseline rate of presentation. Results of a component analysis conducted with 1 subject suggested that stimulus fading accelerated the behavior-reducing effects of extinction.     

Coping, competence, and aggression prevention: Part 2. Universal school-based prevention

Coping—competence theory yields a structural model of the development of persistent aggression in which current challenge encounters determine future life outcomes and competence. Driven by this model, universal, school-based prevention programs would aim in multiple ways to promote prosocial coping among high-risk, resilient, and advantaged youth from kindergarten through high school. Expected benefits of prosocial coping would include: less aggressive behavior, fewer adverse life outcomes (e.g., school dropout, police arrest, teen pregnancy, conduct, mood, and substance-use disorders), and a more competent self-definition and social reputation. Five stages are described that may prove useful in creating prosocial schools and neighborhoods supportive of youth in transition away from antisocial coping and deviant peers.     

The effects of cocaine on behavior maintained by timeout from avoidance.

Rats were trained on concurrent schedules under which responses on one lever postponed shock (avoidance) and responses on the other lever produced brief (2-min) periods of signaled timeout from avoidance. For 6 rats, timeout from avoidance was programmed on a variable-interval 45-s schedule that generally resulted in rates that were lower than those on the avoidance lever. For another 6 rats, timeout was arranged on a variable-ratio 15 schedule that produced higher baseline rates. Cocaine (3 to 40 mg/kg) produced large, dose-dependent increases in behavior maintained by timeout in both groups of rats. Avoidance responding was also generally increased by cocaine, but the increases were of lesser magnitude. Increases in response rates were seen across a broad range of doses on behavior maintained by either interval or ratio schedules, an outcome that was unexpected on the basis of most studies of cocaine on food-maintained behavior. These results were similar to those of previous studies of the effects of amphetamine on behavior maintained by timeout from avoidance and suggest that stimulant drugs affect behavior maintained under a shock-postponement schedule differently than they affect behavior maintained by timeout from avoidance.     

Warmup in avoidance as a function of time since prior training

On avoidance procedures, rats and pigeons typically show warmup effects, characterized by improving performance within sessions and loss of the improvement (“warmup decrement”) between sessions. Between-session losses were examined by varying the time between periods of avoidance training. In one experiment, rats lived fulltime in conditioning chambers while intermission intervals were varied. In a second experiment, the animals lived in home cages between sessions; timeout intervals were introduced at midession, producing recurrence of warmup in the second half-session. In both experiments, the warmup decrements increased substantially as the timeout or intersession intervals were increased from zero to 30 minutes. With intervals of 60 or 120 minutes, the decrements approached or exceeded those obtained with intervals of a day or more. When avoidance was interposed between appetitive sessions, the appetitive responding was disrupted, but this seemed unrelated to the warmup or to the proficiency of avoidance. The warmup in avoidance shares characteristics with transient punishment effects, with the Kamin effect, and with habituation phenomena, but it is premature to assume that they reflect common processes.
