The Children's Dual Emotion Regulation Strategy scale: An integrated perspective of Western and East Asian cultures

The literature on emotion regulation in general lacks cultural and contextual sensitivity and is mainly focused on adult participants. Therefore, we developed the Children's Dual Emotion Regulation Strategy (CDERS) scale as a scenario-based measurement that integrates Western and East Asian cultural perspectives. In Study 1 (N = 1120), six interpersonal conflict scenarios were generated, and each scenario consisted of four emotion regulation strategies (i.e., expression, forbearance, impulsiveness, and suppression), thereby including 24 items in total. A confirmatory factor analysis confirmed the four-factor structure. Concurrent validity revealed that the four strategies in the CDERS accounted for 18%–20% of the variance in predicting positive self-concept and life adjustment. In Study 2 (N = 319), predictive validity revealed that CDERS accounted for 12%–16% of the variance in predicting six outcomes. Incremental validity showed that the CDERS significantly accounted for an additional 3%–11% of the variance in predicting all outcomes above and beyond the existing Western and East Asian emotion regulation measures. The CDERS subscales showed acceptable internal and test–retest reliability. In summary, these studies suggest that the CDERS is a reliable and valid measure. The implications of the results point out suggestions for culturally sensitive practices.     

Childhood Trauma Predicts Positive Expressive Suppression During Social Affiliation in Adults With Anxiety and/or Depression: Implications for Social Functioning

Experiencing childhood trauma (CT) can create barriers for developing relationships and is a risk factor for anxiety and depression. Expressive suppression (ES; i.e., reducing expression associated with experiencing emotions) might explain the link between CT and relationship formation difficulties. We examined the association between (1) CT and ES during a dyadic paradigm intended to facilitate connectedness between unacquainted partners and (2) ES and desire for future interaction (DFI). Individuals with an anxiety or depressive disorder diagnosis (N = 77) interacted with a trained confederate; partners answered a series of increasingly intimate questions about themselves. Participant ES for positive and negative emotions, and participant and confederate DFI were collected during the task. Participants completed global anxiety, depression, and CT measures. CT correlated with positive (r = .35, p = .002), but not negative, ES (r = .13, p = .273). In a multiple linear regression model, CT predicted positive ES beyond symptom variables and gender, β = .318, t = 2.59, p = .012. Positive ES correlated with participant (r = ?.38, p = .001) and confederate DFI (r = ?.40, p<.01); and predicted participant DFI beyond symptom variables and ethnicity, β = ?.358, t = ?3.18, p = .002, and confederate DFI, β = ?.390, t = ?3.51, p = .001, beyond symptom variables. Mediation analyses suggested positive ES accounted for the relationship between greater CT severity and less desire for future interaction from participants, 95%CI [?0.26, ?0.02], and confederates, [?0.38, ?0.01]. Positive ES may be an important factor in the reduced capacity to form new social relationships for individuals with a history of CT, anxiety, and depression.     

Disparagement humor permits unsafe COVID-19 behaviors: A prejudiced norm perspective

Extending prejudiced norm theory, we hypothesized that memes diminishing the severity of the COVID-19 pandemic promote tolerance of unsafe pandemic behaviors (as in contrary to contemporary advice of public health agencies, i.e., not wearing a protective mask) by establishing a perceived norm of tolerance for such behaviors. In Spring 2021, members of several Reddit communities (n = 106) reported their perceived threat of COVID-19 and then completed a roleplay exercise in which they imagined they were with a group of friends in a church setting. In this context, participants viewed memes shared among their friends that belittled COVID-19 (COVID-19 disparagement condition) or memes unrelated to COVID-19 (control condition). Then, participants responded to a vignette describing a woman confronting an usher about a couple who violated protocol by not wearing masks. The results supported our hypothesis. First, participants in the COVID-19 disparagement condition perceived a greater norm of tolerance of the mask protocol violation among others in the immediate context compared to those in the control condition. Second, for participants who viewed COVID-19 as a low threat, that local norm resulted in greater personal tolerance of the mask protocol violation. However, for participants who view COVID-19 as a high threat, the local norm had no impact on their personal tolerance.     

Concurrent phencyclidine and saccharin access: presentation of an alternative reinforcer reduces drug intake.

Six monkeys self-administered orally delivered phencyclidine ("angel dust") and saccharin under concurrent fixed-ratio 16 schedules during daily three-hour sessions. Liquid deliveries were contingent upon lip-contact responses on solenoid-operated drinking spouts. Three saccharin concentrations (0.003%, 0.03% and 0.3%, wt/vol) were tested in a nonsystematic order. For each saccharin concentration, the following series of phencyclidine concentrations (mg/ml) was presented: 0.25, 0.5, 1, 0.25 (retest), 0.125, 0.0625, 0.0312, 0.25 (retest) and 0 (water with stimuli signaling phencyclidine). As the saccharin concentration increased, the number of drug deliveries decreased, and the peaks of the concentration-response functions were shifted to the right. The lowest saccharin concentration (0.003%, wt/vol) maintained responding in excess of phencyclidine levels in only one monkey. The two higher saccharin concentrations maintained behavior far in excess of phencyclidine, but saccharin deliveries decreased in some monkeys as phencyclidine concentration and intake (mg/kg) increased. The time course and patterns of phencyclidine-reinforced responding were also altered when saccharin was concurrently available. The results are discussed in terms of strategies to reduce drug-reinforced behavior, preference between different reinforcers, and measures of reinforcing efficacy.     

MOVEMENT SUPPRESSION TIME-OUT FOR UNDESIRABLE BEHAVIOR IN PSYCHOTIC AND SEVERELY DEVELOP MENTALLY DELAYED CHILDREN

The effects of a movement suppression time-out, which involved punishing any movement or verbalization while a client is in the time-out area, were evaluated in four experiments. The first experiment examined the effects of a DRO procedure and movement suppression plus DRO in suppressing self-injurious behavior in a psychotic child in three different situations. In Experiment 2, the results of the previous experiment were replicated with two dangerous behaviors in a second psychotic child. In a third experiment, movement suppression plus DRO was compared with contingent restraint in reducing inappropriate poking behavior in two settings. The movement suppression procedure eliminated poking whereas contingent restraint had little effect. In the final experiment, movement suppression time-out alone was compared with exclusionary time-out alone and simple corner time-out alone. Self-stimulation occurred at high levels during the exclusionary and simple corner time-out procedures. Self-stimulation was either suppressed or reduced during movement suppression time-out. The movement suppression time-out procedure produced a larger reduction in the target behavior in all three children. The effectiveness of the movement suppression procedure was explained in terms of the suppression of self-stimulation while the time-out procedure was being applied.     

工作记忆中的语音回路与阅读理解的关系

语音回路是Baddeley和Hitch在1974年提出的工作记忆模型中的一个成分。由于语音回路本身的特点,人们联想到它可能和阅读理解这种复杂的认知活动有关系。为此,一些研究者从不同的角度,采用各种研究范式对这一问题进行了探讨。到目前为止,已有的大部分研究都支持语音回路对于阅读理解有作用,但也有少数研究不支持该观点。另外,对于语音回路影响阅读理解的机制问题,也存在着不一致的观点。

The temporal dynamics of visual object priming

Priming reflects an important means of learning that is mediated by implicit memory. Importantly, priming occurs for previously viewed objects (item-specific priming) and their category relatives (category-wide priming). Two distinct neural mechanisms are known to mediate priming, including the sharpening of a neural object representation and the retrieval of stimulus–response mappings. Here, we investigated whether the relationship between these neural mechanisms could help explain why item-specific priming generates faster responses than category-wide priming. Participants studied pictures of everyday objects, and then performed a difficult picture identification task while we recorded event-related potentials (ERP). The identification task gradually revealed random line segments of previously viewed items (Studied), category exemplars of previously viewed items (Exemplar), and items that were not previously viewed (Unstudied). Studied items were identified sooner than Unstudied items, showing evidence of item-specific priming, and importantly Exemplar items were also identified sooner than Unstudied items, showing evidence of category-wide priming. Early activity showed sustained neural suppression of parietal activity for both types of priming. However, these neural suppression effects may have stemmed from distinct processes because while category-wide neural suppression was correlated with priming behavior, item-specific neural suppression was not. Late activity, examined with response-locked ERPs, showed additional processes related to item-specific priming including neural suppression in occipital areas and parietal activity that was correlated with behavior. Together, we conclude that item-specific and category-wide priming are mediated by separate, parallel neural mechanisms in the context of the current paradigm. Temporal differences in behavior are determined by the timecourses of these distinct processes.
