EXPRESS: Rejections Are Stickier than Choices

Consumers frequently make the same decision repeatedly, by either choosing the products they like more or rejecting the products they like less. Holding everything else constant, does the mere act of choosing versus rejecting influence the extent to which consumers seek variety? Eight studies ( N = 2,814) identify a robust effect: consumers tend to seek less variety across repeated decisions if they make each decision by rejecting than if they make each decision by choosing. This effect occurs because an initial rejection (vs. choice) reduces the liking of the unselected option(s) and thus widens the liking gap between the selected and unselected options. An increased liking gap, in turn, decreases the consumer’s likelihood of selecting a previously unselected option(s) in subsequent decisions. We also show that the enlarged liking gap is driven by increased negative inferences about the unselected option(s). Theoretically, this research extends the literatures on variety seeking and choosing versus rejecting. Practically, it offers implications for consumer welfare: the rejection task can improve (worsen) the decision quality in situations in which consumers typically seek too much (too little) variety.

Adaptive neuro-fuzzy inference system based active force control with iterative learning for trajectory tracking of a biped robot

ABSTRACT We investigate the integration of the active force control (AFC) scheme and the adaptive neuro-fuzzy inference system (ANFIS) as an intelligent controller algorithm to address trajectory-tracking problems in robotic systems, The AFC-ANFIS model exploits iterative learning (IL) to improve the tracking performance based on its trained model. The ANFIS parameters are tuned using both particle swarm optimisation (PSO) and beetle antennae search (BAS) algorithms. The simulation results of two different robots, i.e. a five-link biped robot and a PUMA 560 robot arm, indicate that the proposed AFC-ANFIS controller performs well for trajectory tracking and disturbances rejection. The AFC-ANFIS performance is evaluated and compared with those from other controllers using the average tracking error (ATE) metric. The comparative results reveal that AFC-ANFIS offers a viable approach with a rapid training process to undertaking trajectory tracking and disturbance rejection tasks.

Adaptive dynamic‐surface repetitive control for uncertain nonlinear systems with mismatched disturbances and input delay

AbstractBased on additive state decomposition technique, this article presents an adaptive dynamic‐surface repetitive control method for a class of uncertain nonlinear systems with mismatched disturbances and input delay. First, the original uncertain nonlinear system is decomposed into a linear time invariant (LTI) primary system responsible for the periodic signal tracing and rejection task, and a nonlinear secondary system with input time delay responsible for the robust stabilization task. A modified repetitive controller with a small correction to the delay constant is then independently designed for the LTI primary system, while an adaptive dynamic surface controller is designed for the nonlinear secondary system. Stability analysis is performed for each subsystem and the design procedure of the whole system is presented in detail. Finally, comparative simulations with other repetitive control and dynamic surface control methods show that the presented method not only relaxes the constraints on the reference inputs and exogenous disturbances, but also ensures that the system has better disturbance rejection and periodic‐signal tracking performance in both transient and steady states. As a result, this method broadens the application of both repetitive control and dynamic surface control.

Radar High-Resolution Range Profile Rejection Based on Deep Multi-Modal Support Vector Data Description

Radar Automatic Target Recognition (RATR) based on high-resolution range profile (HRRP) has received intensive attention in recent years. In practice, RATR usually needs not only to recognize in-library samples but also to reject out-of-library samples. However, most rejection methods lack a specific and accurate description of the underlying distribution of HRRP, which limits the effectiveness of the rejection task. Therefore, this paper proposes a novel rejection method for HRRP, named Deep Multi-modal Support Vector Data Description (DMMSVDD). On the one hand, it forms a more compact rejection boundary with the Gaussian mixture model in consideration of the high-dimensional and multi-modal structure of HRRP. On the other hand, it captures the global temporal information and channel-dependent information with a dual attention module to gain more discriminative structured features, which are optimized jointly with the rejection boundary. In addition, a semi-supervised extension is proposed to refine the boundary with available out-of-library samples. Experimental results based on measured data show that the proposed methods demonstrate significant improvement in the HRRP rejection performance.

The smallest things make me emotional! Emotion reactivity in non-suicidal self-injury: trait, state, and physiological differences.

The current study sought to clarify the role of emotion reactivity in non-suicidal self-injury (NSSI) by examining three forms of emotion reactivity (physiological and self-reported trait and state reactivity) among a sample of young adults with or without a history of NSSI. Seventy-six adults (M age = 20.97, 73.7% female) participated in a semi-structured clinical interview to determine NSSI history and completed a measure of trait emotion reactivity. Participants then provided state emotion reactivity ratings before and after a social rejection task, recovery period, and positive mood induction while physiological data was continuously recorded. Although individuals with a history of NSSI perceived themselves to be more emotionally reactive, these participants were not more physiologically reactive, nor were their state reactivity ratings significantly different from individuals without a history of NSSI. Results suggest increased emotionality in response to a stressor is within normal bounds and not unique to individuals with a history of NSSI, and provide implications for future research on the etiology and treatment of NSSI.

Performance comparison between PID, PIDD2 and PIDD2α

We evaluate the performance achievable with Proportional-Integral-Derivative fractional Double-Derivative controllers, denoted as PIDD2α, by comparing it with that achievable with standard PID controllers and with Proportional-Integral-Double-Derivative (PIDD or PIDD2) controllers, which are also called Proportional-Integral-Derivative-Acceleration (PIDA) controllers. The cost-effectiveness ratio improvement obtained when augmenting the control law with an element proportional to the fractional second derivative of the control error is assessed by considering different process transfer functions and by tuning the controllers minimizing the integrated absolute error with genetic algorithms. Further, a constraint on the maximum sensitivity is also posed so that the system robustness is taken into account. The set-point following and the load disturbance rejection tasks are evaluated separately.

Negative feedback-seeking in depression: The moderating roles of rumination and interpersonal life stress.

Swann's self-verification theory proposes that negative feedback seeking (NFS)-the solicitation of negative feedback from others that confirms one's self-views-works in a negative cycle to maintain and exacerbate depression in the face of interpersonal stress. We propose a cognitive-interpersonal integration account of NFS such that this maladaptive behavior prospectively predicts depression only among those with a trait tendency to ruminate on the causes and consequences of depressed mood and stress. Participants included 91 young adults who were over-sampled for a lifetime history of a unipolar depressive disorder (age 17-33; 69% women; 67% lifetime depressive disorder). At baseline, participants completed a structured diagnostic interview and self-report measures of NFS, rumination, and depression symptoms. In addition, participants engaged in an interpersonal rejection task (the Yale Interpersonal Stressor) followed by a behavioral measure of NFS. At a 3-month follow-up, depression symptoms were again assessed by self-report and exposure to stressful interpersonal life events in the intervening period were assessed with a rigorous contextual interview and independent rating system. Controlling for baseline depression severity, greater self-reported, and behaviorally assessed NFS predicted greater follow-up depression severity, but only among those with higher trait tendency to ruminate. For self-reported NFS, this association was further moderated by level of interpersonal, but not noninterpersonal, life events experienced over follow-up. These findings suggest that rumination may represent a modifiable intervention target that could break the vicious interpersonal cycle of depression and, thus, mitigate the depressogenic effects of NFS.

Allostatic-interoceptive anticipation of social rejection

Anticipating social stress evokes strong reactions in the organism, including interoceptive modulations. However, evidence for this claim comes from behavioral studies, often with inconsistent results, and relates almost solely to the reactive and recovery phase of social stress exposure. Here, we adopted an allostatic-interoceptive predictive coding framework to study interoceptive and exteroceptive anticipatory brain responses using a social rejection task. We analyzed the heart-evoked potential (HEP) and task-related oscillatory activity of 58 adolescents via scalp EEG, and 385 human intracranial recordings of three patients with intractable epilepsy. We found that anticipatory interoceptive signals increased in the face of unexpected social outcomes, reflected in larger negative HEP modulations. Such signals emerged from key brain allostatic-interoceptive network hubs, as shown by intracranial recordings. Exteroceptive signals were characterized by early activity between 1-15 Hz across conditions, and modulated by the probabilistic anticipation of reward-related outcomes, observed over distributed brain regions. Our findings suggest that the anticipation of a social outcome is characterized by allostatic-interoceptive modulations that prepare the organism for possible rejection. These results inform our understanding of interoceptive processing and constrain neurobiological models of social stress.

ACT-R based human digital twin to enhance operators' performance in process industries.

To ensure safe and efficient operation, operators in process industries have to make timely decisions based on time-varying information. A holistic assessment of operators' performance is, therefore, challenging. Current approaches to operator performance assessment are subjective and ignore operators' cognitive behavior. In addition, these cannot be used to predict operators' expected responses during novel situations that may arise during plant operations. The present study seeks to develop a human digital twin (HDT) that can simulate a control room operator's behavior, even during various abnormal situations. The HDT has been developed using the ACT-R (Adaptive Control of Thought-Rational) cognitive architecture. It mimics a human operator as they monitor the process and intervene during abnormal situations. We conducted 426 trials to test the HDT's ability to handle disturbance rejection tasks. In these simulations, we varied the reward and penalty parameters to provide feedback to the HDT. We validated the HDT using the eye gaze behavior of 10 human subjects who completed 110 similar disturbance rejection tasks as that of the HDT. The results indicate that the HDT exhibits similar gaze behaviors as the human subjects, even when dealing with abnormal situations. These indicate that the HDT's cognitive capabilities are comparable to those of human operators. As possible applications, the proposed HDT can be used to generate a large database of human behavior during abnormalities which can then be used to spot and rectify flaws in novice operator's mental models. Additionally, the HDT can also enhance operators' decision-making during real-time operation.

Optimized tuning rules for proportional‐integral controllers with selected robustness

AbstractIn this paper, we present tuning rules for PI controllers that represent an effective alternative to the well‐known lambda‐tuning for the load disturbance rejection task. In particular, the integrated absolute error is minimized subject to a constraint on the maximum sensitivity selected. Suitable formulas are given to relate the proposed tuning with the lambda‐tuning, and the improvement obtained is quantified for different process dynamics. Both self‐regulating and non self‐regulating processes are considered. Simulation results are given to illustrate the methodology.

Rejection sensitivity and mu opioid receptor dynamics associated with mood alterations in response to social feedback

Rejection sensitivity (RS) is the heightened expectation or perception of social rejection and is a feature of many psychiatric disorders. As endogenous opioid pathways have been implicated in response to social rejection and reward, we hypothesize that RS will be negatively associated with mu opioid receptor (MOR) baseline binding and activity during rejection and acceptance stimuli. In exploratory analyses, we assessed the relationships between MOR activity and changes in mood and self-esteem before and after stimuli. Healthy participants, N = 75 (52% female), completed rejection and acceptance tasks during [11C]carfentanil positron emission tomography (PET) scans. MOR activity in the amygdala, midline thalamus, anterior insula, and nucleus accumbens (NAc) was evaluated. RS was not related to MOR baseline binding potential or activity during acceptance or rejection tasks in any region. Increased MOR activity in the NAc was associated with increase in ratings of self-esteem and positive mood during the period between acceptance task administration and approximately 5 min after the task completion. Our results suggest that endogenous opioid response to social rejection is independent of RS in healthy individuals. MOR activity in the NAc was associated with increase self-esteem and positive mood after experiencing social feedback, warranting further investigation.

Autonomic reactivity to social rejection, peer difficulties, and the buffering effects of adolescent friendships following early psychosocial deprivation.

Autonomic nervous system reactivity has been posited to be a mechanism contributing to social and emotional problems among children exposed to early adversity. Leveraging data from the Bucharest Early Intervention Project, a longitudinal randomized controlled trial of foster care versus institutional care of abandoned children in Romania, we assessed whether altered sympathetic reactivity to peer rejection feedback in early adolescence mediated the relation between early institutional rearing and peer problems in later adolescence. We also assessed whether adolescent friendship quality or randomized placement in foster care early in life moderated these associations. Participants include 68 institutionalized children randomized to care as usual, 68 institutionalized children randomized to foster care, and 135 never-institutionalized children. At age 12, participants reported friendship quality with respect to a best friend and completed a social rejection task while electrocardiogram and impedance cardiography were recorded. Sympathetic nervous system reactivity to rejection feedback was assessed using preejection period (PEP). At ages 12 and 16, peer problems were reported by parents. Mediation analysis revealed that less PEP reactivity to social rejection at age 12 partially mediated the association between early institutionalization and greater peer problems at age 16. Further moderated mediation analysis revealed that this indirect effect was evidenced among previously institutionalized youths with low, but not high, quality friendships. We did not observe foster care intervention effects. These findings suggest that altered sympathetic reactivity to social rejection might be a mechanism linking early institutionalization to social difficulties into adolescence, however, positive adolescent friendships may buffer these effects.

Mindfulness, rejection, and recovery of positive mood and friendliness: A Cyberball study.

Experiencing stressful events that threaten feelings of social belonging can have far-reaching negative impacts on well-being, but there are individual differences in sensitivity to threat that might be explained by dispositional traits. In particular, naturally occurring dispositional mindfulness may be one trait that can explain such differences. To test this possibility, a pool of 495 young adults completed a measure of dispositional mindfulness and a subset of 90 (M = 19 years, SD = 1.3), selected to represent the full range of mindfulness scores, participated in an induced social rejection task (Cyberball). Threat appraisal was collected by asking about perceived exclusion and rejection post-Cyberball, and participants reported their mood and friendliness before, after, and at 3-mins of recovery, and their self-esteem and life meaning after Cyberball and at recovery. Participants higher in mindfulness reported better mood and less unfriendliness prior to Cyberball. Directly after playing Cyberball, a more heightened appraisal of threat, but not mindfulness, was associated with worse mood, less friendliness, lower self-esteem, and less life meaning. Mindfulness directly mitigated the negative effects of rejection on feelings of friendliness post rejection. When mindfulness and threat appraisal were considered in interaction, the association of perceived threat with pre- to post- changes in positive mood and friendliness was strongly negative when mindfulness was high relative to low. Further, mindfulness was associated with better recovery of mood and life meaning by 3-min after Cyberball, and these effects were additive rather than interactive.

Accentuation and compatibility: Replication and extensions of Shafir (1993) to rethink choosing versus rejecting paradigms

AbstractWe conducted a replication of Shafir (1993) who showed that people are inconsistent in their preferences when faced with choosing versus rejecting decision-making scenarios. The effect was demonstrated using an enrichment paradigm, asking subjects to choose between enriched and impoverished alternatives, with enriched alternatives having more positive and negative features than the impoverished alternative. Using eight different decision scenarios, Shafir found support for a compatibility principle: subjects chose and rejected enriched alternatives in choose and reject decision scenarios (d= 0.32 [0.23,0.40]), respectively, and indicated greater preference for the enriched alternative in the choice task than in the rejection task (d= 0.38 [0.29,0.46]). In a preregistered very close replication of the original study (N= 1026), we found no consistent support for the hypotheses across the eight problems: two had similar effects, two had opposite effects, and four showed no effects (overalld= −0.01 [−0.06,0.03]). Seeking alternative explanations, we tested an extension, and found support for the accentuation hypothesis.

Range-Doppler Spectrograms-Based Graph-Relational Mapping for Clutter Rejection in HF Passive Radar

Clutter rejection is a key technique for high-frequency passive radar (HFPR). To solve this problem, the traditional signal processing methods have been used, which mainly depend on prior information of the feature differences between target and clutter in time, space, or frequency domain. As a new attempt to deep-mine the clutter feature automatically and reject it by only data-driven processing, a novel clutter rejection method based on graph-relational mapping using a deep learning network is proposed in this letter. In this method, the clutter rejection problem is turned into an image-to-image translation problem between the range-Doppler (RD) spectrograms before and after clutter rejection. A deep-learning-enabled image translation network (CycleGAN) is exploited to learn from training data of RD spectrograms and to establish the mapping relationship. When processing clutter rejection tasks, the trained network can automatically extract clutter features without prior information and save manpower. The performance evaluations of the novel clutter rejection method are also investigated, and the experimental results confirm that the proposed method can effectively reject clutter in HFPR.

Performance assessment of controller designed for electrical systems with second order dynamics

PurposeAn assessment technique that analyzes the servo and regulatory characteristics of the proportional integral derivative controller is designed for time-delayed second-order stable processes.Design/methodology/approachThe minimum theoretical error expression for integral of the absolute errors (IAE_o) is obtained from the preferred servo and regulatory transfer functions dependent on the step changes in reference and load variables.FindingsThe error-based index is outlined to estimate the controller that is derived using internal model-based control or direct synthesis method. The ratio between derived IAE_o and the IAE_actual gained from the loop response that experiences step input variations gives rise to a dimensionless error index. This error index measures the behaviour of the controller by considering the index value. If the error index value is larger than 0.8, then the effort taken by the controller is good or else retuning is expected.Originality/valueThe efficacy of the index to validate the controller is verified by applying on a few second-order electrical processes. The results are simulated for both reference tracking and load rejection tasks to demonstrate the rationality of the presented index.

Development of the A-DISS rejection task to demonstrate the unique and overlapping affective features of social anxiety and depression.

Social anxiety (SA) and depression are prevalent, often comorbid disorders, associated with poor psychosocial functioning. Experimental psychopathology approaches can clarify the transdiagnostic mechanisms underlying these disorders, but most laboratory tasks are limited. We developed and validated the Audio-Dialogue Inductions of Social Stress (A-DISS) experimental task to model real-time rejection sensitivity in a realistic and developmentally relevant context. Participants are asked to imagine overhearing peers at a party talking badly about them (Rejection) or a teacher at their school (Neutral). Study 1 focused on identifying and refining stimuli that elicited relevant emotional responses for Rejection (e.g., increased anxiety) and Neutral (e.g., no emotional changes) conditions (N=48). Study 2 examined whether participants' SA and depression symptoms moderated the effects of A-DISS condition (N=52). The Rejection condition elicited higher negative affect/lower positive affect while the Neutral condition sustained stable affect. Findings were consistent across gender and race/ethnicity. Moderation analyses were statistically significant; participants with elevated SA or depression reported feeling more rejected, insecure, and anxious after Rejection than those with below average symptoms. Findings provide preliminary validation of a novel peer rejection task for research on understanding the affective experience of real-time rejection overall, especially for those with elevated SA and depression. SA and depression symptoms each uniquely moderating the effects of Rejection exposure on similar affective states, suggests individuals with SA or depression may benefit from interventions targeting specific reactions to rejection/stress and transdiagnostic risk factors.

A Novel Deep Learning Model for the Detection and Identification of Rolling Element-Bearing Faults.

Real-time acquisition of large amounts of machine operating data is now increasingly common due to recent advances in Industry 4.0 technologies. A key benefit to factory operators of this large scale data acquisition is in the ability to perform real-time condition monitoring and early-stage fault detection and diagnosis on industrial machinery—with the potential to reduce machine down-time and thus operating costs. The main contribution of this work is the development of an intelligent fault diagnosis method capable of operating on these real-time data streams to provide early detection of developing problems under variable operating conditions. We propose a novel dual-path recurrent neural network with a wide first kernel and deep convolutional neural network pathway (RNN-WDCNN) capable of operating on raw temporal signals such as vibration data to diagnose rolling element bearing faults in data acquired from electromechanical drive systems. RNN-WDCNN combines elements of recurrent neural networks (RNNs) and convolutional neural networks (CNNs) to capture distant dependencies in time series data and suppress high-frequency noise in the input signals. Experimental results on the benchmark Case Western Reserve University (CWRU) bearing fault dataset show RNN-WDCNN outperforms current state-of-the-art methods in both domain adaptation and noise rejection tasks.

Examining the impact of online rejection among emerging adults with borderline personality pathology: Development of a novel online group chat social rejection paradigm.

Borderline personality disorder (BPD) is characterized by emotional reactivity and interpersonal sensitivity, including greater emotional and cognitive reactivity to social rejection than controls. However, existing social rejection paradigms are not relevant to the particular social contexts that are increasingly relevant for adolescents and young adults (i.e., social media and online settings). This study examined emotional, parasympathetic, and cognitive responses to a novel online group chat social interaction task among emerging adults (18-24 years old) with a range of BPD pathology. Consistent with hypotheses, results revealed greater hostility and upset feelings, worse mood, greater threat to social needs, and greater respiratory sinus arrhythmia withdrawal in response to this task among participants in the rejection versus inclusion condition. Less support was found for the hypothesized relation of BPD pathology to greater reactivity to online social rejection. Specifically, although results revealed positive relations of BPD pathology with both negative mood in general and hostility in particular, in response to the task among participants in the rejection (but not inclusion) condition, the effect sizes associated with these findings were small, and the other hypothesized interactions of BPD pathology and group chat task condition were not significant. Conversely, results revealed associations of BPD pathology with greater threat to social needs and lower positive mood in response to the group chat task, regardless of condition. Results provide preliminary support for the utility of this novel online group chat rejection task for eliciting negative emotional, parasympathetic, and cognitive reactions in emerging adults with a range of BPD pathology.

Cortical activity during social acceptance and rejection task in social anxiety disorder: A controlled functional near infrared spectroscopy study

BackgroundThe cognitive and emotional vulnerability of individuals with social anxiety disorder (SAD) and their response to repeated experiences of social rejection and social acceptance are important factors for the emergence and maintenance of symptoms of the disorder. Functional neuroimaging studies of SAD reveal hyperactivity in regions involved in the fear circuit such as amygdala, insula, anterior cingulate, and prefrontal cortices (PFC) in response to human faces with negative emotions. Observation of brain activity, however, involving studies of responses to standardized human interaction of social acceptance and social rejection have been lacking. MethodsWe compared a group of index subjects with SAD (N = 22, mean age:26.3 ± 5.4, female/male: 7/15) (SADG) with a group of healthy controls (CG) (N = 21, mean age:28.7 ± 4.5, female/male: 14/7) in measures of cortical activity during standardized experiences of human interaction involving social acceptance (SA) and social rejection (SR) video-simulated handshaking tasks performed by real actors. In a third, control condition (CC), the subjects were expected to press a switch button in an equivalent space. Subjects with a concurrent mood episode were excluded and the severity of subclinical depressive symptoms was controlled. 52-channel functional near-infrared spectroscopy (fNIRS) was used to measure cortical activity. ResultsActivity was higher in the SAD subjects compared to healthy controls, in particular in channels that project to middle and superior temporal gyri (STG), frontal eye fields (FEF) and dorsolateral prefrontal cortex (DLPFC) in terms of both SA and SR conditions. Cortical activity during the CC was not different between the groups. Only in the SAD-group, activity in the pre-motor and supplementary motor cortices, inferior and middle temporal gyri and fronto-polar area was higher during the rejection condition than the other two conditions. Anxiety scores were correlated with activity in STG, DLPFC, FEF and premotor cortex, while avoidance scores were correlated with activity in STG and FEF. ConclusionsSA and SR are represented differently in terms of cortical activity in SAD subjects compared to healthy controls. Higher activity in both social conditions in SAD subjects compared to controls may imply biological sensitivity to these experiences and may underscore the importance of increased cortical activity during social interaction experiences as a putative mediator of vulnerability to SAD. Higher cortical activity in the SADG may possibly indicate stronger need for inhibitory control mechanisms and higher recruitment of theory of mind functions during social stress. Higher activity during the SR compared to the SA condition in the SAD subjects may also suggest distinct processing of social cues, whether they involve acceptance or rejection.
