Abstract construal levels attenuate state self-esteem reactivity

The reactivity of state self-esteem has been linked to a number of important psychological outcomes, ranging from general well-being to psychological dysfunction. The present research aimed to identify a cognitive factor underlying state self-esteem reactivity by exploring how construal levels influence the extent to which state self-esteem reacts to positive and negative experiences. It was hypothesized that abstract construals would mitigate the effects of evaluative information on state self-esteem. The results of two studies supported this hypothesis. Participants in an abstract mindset did not differ in state self-esteem after receiving positive, negative, or no evaluative information. Participants in a concrete mindset, in contrast, experienced lower levels of state self-esteem following negative evaluative information. The significance of these findings for understanding the link between abstraction and psychological vulnerability is discussed.     

Replications and extensions in arousal assessment for sex offenders with developmental disabilities

Three adult male sex offenders with developmental disabilities participated in phallometric assessments that involved repeated measures of arousal when exposed to various stimuli. Arousal assessment outcomes were similar to those obtained by Reyes et al. (2006). Additional data-analysis methods provided further information about sexual preferences, thus replicating and extending previous research. The results provide preliminary data for establishing a preference gradient by age. Implications for the use of repeated measures and preference gradients in arousal assessments are discussed.     

Positive experiences of high arousal martial arts rituals are linked to identity fusion and costly pro-group actions

A cross-sectional study was conducted with 605 practitioners of Brazilian Jiu Jitsu (BJJ) to test the hypothesis that high arousal rituals promote social cohesion, primarily through identity fusion. BJJ promotion rituals are rare, highly emotional ritual events that often feature gruelling belt-whipping gauntlets. We used the variation in such experiences to examine whether more gruelling rituals were associated with identity fusion and pro-group behaviour. We found no differences between those who had undergone belt-whipping and those who had not and no evidence of a correlation between pain and social cohesion. However, across the full sample we found that positive, but not negative, affective experiences of promotional rituals were associated with identity fusion and that this mediated pro-group action. These findings provide new evidence concerning the social functions of collective rituals and highlight the importance of addressing the potentially diverging subjective experiences of painful rituals.     

Arousal, changeover responses, and preference in concurrent schedules

Pigeons were trained on multiple schedules that provided concurrent reinforcement in each of two components. In Experiment 1, one component consisted of a variable-interval (VI) 40-s schedule presented with a VI 20-s schedule, and the other a VI 40-s schedule presented with a VI 80-s schedule. After extended training, probe tests measured preference between the stimuli associated with the two 40-s schedules. Probe tests replicated the results of Belke (1992) that showed preference for the 40-s schedule that had been paired with the 80-s schedule. In a second condition, the overall reinforcer rate provided by the two components was equated by adding a signaled VI schedule to the component with the lower reinforcer rate. Probe results were unchanged. In Experiment 2, pigeons were trained on alternating concurrent VI 30-s VI 60-s schedules. One schedule provided 2-s access to food and the other provided 6-s access. The larger reinforcer magnitude produced higher response rates and was preferred on probe trials. Rate of changeover responding, however, did not differ as a function of reinforcer magnitude. The present results demonstrate that preference on probe trials is not a simple reflection of the pattern of changeover behavior established during training.     

Perceiving arousal and valence in facial expressions: Differences between children and adults

Arousal and valence have long been studied as the two primary dimensions for the perception of emotional stimuli such as facial expressions. Prior correlational studies that tested emotion perception along these dimensions found broad similarities between adults and children. However, few studies looked for direct differences between children and adults in these dimensions beyond correlation. We tested 9-year-old children and adults on rating positive and negative facial stimuli based on emotional arousal and valence. Despite high significant correlations between children’s and adults’ ratings, our findings also showed significant differences between children and adults in terms of rating values: Children rated all expressions as significantly more positive than adults in valence. Children also rated positive emotions as more arousing than adults. Our results show that although perception of facial emotions along arousal and valence follows similar patterns in children and adults, some differences in ratings persist, and vary by emotion type.     

Divided attention enhances the recognition of emotional stimuli: evidence from the attentional boost effect

The present study examined predictions of the early-phase-elevated-attention hypothesis of the attentional boost effect (ABE), which suggests that transient increases in attention at encoding, as instantiated in the ABE paradigm, should enhance the recognition of neutral and positive items (whose encoding is mostly based on controlled processes), while having small or null effects on the recognition of negative items (whose encoding is primarily based on automatic processes). Participants were presented a sequence of negative, neutral and positive stimuli (pictures in Experiment 1, words in Experiment 2) associated to target (red) squares, distractor (green) squares or no squares (baseline condition). They were told to attend to the pictures/words and simultaneously press the spacebar of the computer when a red square appeared. In a later recognition task, stimuli associated to target squares were recognised better than stimuli associated to distractor squares, replicating the standard ABE. More importantly, we also found that: (a) the memory enhancement following target detection occurred with all types of stimuli (neutral, negative and positive) and (b) the advantage of negative stimuli over neutral stimuli was intact in the DA condition. These findings suggest that the encoding of negative stimuli depends on both controlled (attention-dependent) and automatic (attention-independent) processes.     

The impact of pre-sleep arousal state and strategy to control unwanted thoughts on sleep quality

Objective: It has been questioned whether elevated pre-sleep cognitive arousal contributes to poor sleep or whether it is the use of maladaptive thought control strategies, used to manage this cognitive arousal, that are responsible. The study aimed to examine how these factors – cognitive arousal (with and without anxiety) and maladaptive thought control strategies contribute to perceived sleep quality (SQ). Design: 129 “healthy adults” (46 males, 83 females) were exposed to picture-stimuli eliciting either anxious cognitive arousal or non-anxious cognitive arousal at bedtime. The groups were then randomly split and briefed to use either a cognitive distraction or cognitive suppression thought control strategy or no instructions were given (controls). Subjective SQ was measured immediately on waking. Results: Induced anxious cognitive arousal was associated with lower SQ compared to non-anxious cognitive arousal. Analyses revealed a significant interaction between arousal and the strategies used to control unwanted thoughts on SQ. When experiencing anxious cognitive arousal, the strategy of distraction was associated with poorer sleep outcomes. Conclusion: The findings suggest that the efficacy of differing thought control strategies vary depending upon whether cognitive arousal elicits anxiety or not. With that in mind, clinical implications in terms of augmenting the treatment of insomnia are discussed.
