Quick to Act,Quick to Forget: The Link Between Impulsiveness and Prospective Memory

Several traits of impulsiveness (e.g. lack of planning and perseverance, difficulty focusing attention) seem intimately connected to the skills required for successful prospective memory performance. This is the first study to examine whether the various inter‐correlated dimensions of impulsiveness are related to problems with prospective memory. Undergraduate students (N = 184) completed the Barratt Impulsiveness Scale 11, the Prospective Memory Questionnaire, the Prospective and Retrospective Memory Questionnaire, and two objective prospective memory tests. Results revealed consistent correlations between the various dimensions of impulsiveness (attentional, motor, non‐planning) and self‐reported problems with prospective memory. Subsequent regression analyses indicated that attentional impulsiveness is a unique predictor of self‐reported problems with internally cued prospective memory, and non‐planning impulsiveness is a unique predictor of self‐reported problems with episodic and overall prospective memory. Similarly, findings from the objective prospective tests showed that non‐planning impulsiveness was related to worse performance on the two prospective memory tests. Whereas non‐planning impulsiveness was also related to using fewer prospective memory‐aiding strategies, mediation analyses showed that use of these strategies does not account for any of the detected relationships. Because the findings suggest that a failure to plan does not underlie the detected effects, other potential explanations for the relationships are discussed.

The Role of Stimulus Type and Semantic Category‐Level Attentional Set in Sustained Inattentional Blindness

Abstract: We examined the effect of the stimulus type and semantic categorization of the unexpected stimulus on sustained Inattentional Blindness (IB). Results showed that observers could establish attentional set based on a higher level of semantic categorization, which tuned one's attention to prioritizing semantic content over others. The unexpected stimulus, congruent with the attended objects in semantic categorization, was more likely to be noticed, whereas the incongruent semantic stimulus seemed to be unseen. Semantic category‐level attentional set played a crucial role in breaking through IB. The semantically congruent Chinese characters stimulus was detected and recognized more often than a semantically congruent picture stimulus, indicating that Chinese characters had more power to attract attention to escape sustained IB than pictures involved in visual processing. Presumably the finding of Chinese characters breaking through IB more easily might be due to the fact that Chinese characters look more distinct from pictures, rather than Chinese characters being processed more easily. Further research should be taken to test the semantic processing efficiency between pictures and Chinese characters in sustained IB.     

目标决策还是动作诱发?动作反应对注意促进效应的影响

注意促进效应(ABE)指的是在双任务条件下, 伴随探测任务的目标刺激呈现的背景信息记忆成绩要优于伴随分心刺激呈现的背景信息记忆成绩的现象。以往研究主张, ABE的产生主要源于目标决策时所诱发的注意增强。但由于目标探测往往伴随着动作反应, 而已有研究发现, 动作反应就能直接诱发背景信息的记忆增强效应, 因此ABE也可能源于动作诱发的记忆增强效应。为此, 研究设置了NoGo目标探测条件与Go目标探测条件, 通过4个实验系统地探讨了动作反应与目标决策在ABE产生中的作用及关系。结果表明, Go目标探测条件下的ABE是稳定的, 但NoGo目标探测条件下的ABE会受到动作反应频率对分心词的影响。此外, NoGo目标探测跨条件的ABE也是非常稳定的。这些结果表明, 目标决策产生的注意促进作用是相对稳定的, 但ABE的产生更多是目标决策的促进作用与动作诱发的记忆增强效应动态权衡后的结果。

Under what conditions do children have difficulty in inhibiting imitation? Evidence for the importance of planning specific responses

The response set effect has been observed in a number of developmental tasks that are proposed to required inhibition. This effect has been interpreted as evidence that the specific responses children plan to make in these tasks become prepotent. Here we investigated whether there is a response set effect in the hand game. In this task, children need to suppress imitation and make a fist in response to a finger and point a finger in response to a fist. Following pilot data, we tested 7- and 11-year-olds (N=36, Experiment 1) and then 5- and 6-year-olds (N=40, Experiment 2). A response set effect was observed in the hand game with children 6years of age and older. Thus, we obtained evidence consistent with a domain-general intentional mechanism that modulates prepotency. In the General discussion, we consider how this mechanism may work and how our findings relate to current theories of imitation.     

The effects of attention retraining on depressive mood and cortisol responses to depression‐related stimuli1

Although it has been reported that attentional bias at an early stage is found in depression, no study has investigated the effects of modification of attentional bias at an early stage on depressive mood and cortisol response to a stressor. Therefore, this study tested the hypotheses that the modification of attentional bias at an early stage would reduce depressive mood and cortisol response. Fifty‐three participants were allocated alternately either to the training or the control group. They were administered attention retraining for modification of attentional bias or a sham attention task, and then underwent a stress task. With respect to depressive mood response, depressive mood increased in response to a stress task in the control group, while for high‐dysphoric participants in the training group, depressive mood response remained constant. These results indicate that attention retraining is efficacious for reducing depressive mood response. With respect to cortisol response, the percentage change in cortisol is associated with the amount of change in the attentional bias index scores. The results suggest the possibility that attention retraining could reduce cortisol response.     

Attentional sensitization of unconscious visual processing: Top-down influences on masked priming

Classical theories of automaticity assume that automatic processes elicited by unconscious stimuli are autonomous and independent of higher-level cognitive influences. In contrast to these classical conceptions, we argue that automatic processing depends on attentional amplification of task-congruent processing pathways and propose an attentional sensitization model of unconscious visual processing: According to this model, unconscious visual processing is automatic in the sense that it is initiated without deliberate intention. However, unconscious visual processing is susceptible to attentional top-down control and is only elicited if the cognitive system is configured accordingly. In this article, we describe our attentional sensitization model and review recent evidence demonstrating attentional influences on subliminal priming, a prototypical example of an automatic process. We show that subliminal priming (a) depends on attentional resources, (b) is susceptible to stimulus expectations, (c) is influenced by action intentions, and (d) is modulated by task sets. These data suggest that attention enhances or attenuates unconscious visual processes in congruency with attentional task representations similar to conscious perception. We argue that seemingly paradoxical, hitherto unexplained findings regarding the automaticity of the underlying processes in many cognitive domains can be easily accommodated by our attentional sensitization model. We conclude this review with a discussion of future research questions regar-ding the nature of attentional control of unconscious visual processing.     

Increased Attentional Control for Emotional Distractors Moderates the Use of Reflective Pondering in Times of Life Stress: A Prospective Study

According to the response styles theory, rumination is a cognitive response to a stressor with repetitive and self‐focused attention on a negative mood state. The attentional disengagement theory highlights that attentional processes are critical, underlying individual differences in ruminative thinking, such as reflective pondering and depressive brooding. Using a prospective design, the current study sought to determine whether attentional control for negative material was differently associated with brooding and reflection upon life stress. Spanning a period of three months, 76 never depressed undergraduate students completed a baseline measurement of attentional bias by using an emotional modification of the exogenous cueing task (T1) and subsequently, six weeks after T1, completed Internet questionnaires during their final examinations at four weekly fixed moments (T2–T5). Data were analysed with a series of multilevel regression analyses. Results revealed that the relation between stress and the use of reflective pondering is stronger when participants allocate less attention to emotional information (negative and positive stimuli). On the other hand, attentional control did not moderate the relation between stress and depressive brooding. On the basis of the current research findings, it might be important to train attentional control to disengage from emotional distractors, which in turn may increase the use of more self‐controlling thinking in response to stress.

Attentional bias toward waiting time information among individuals with high and low trait self-control when making intertemporal choices

ABSTRACT

The present study aimed to explore whether the modulation effects of attentional biases toward time information representing immediate rewards and delayed rewards differ between individuals with high and low trait self-control. Forty participants with high trait self-control and 40 with low trait self-control were selected based on their responses to the Chinese version of the self-control scale, and they were asked to complete an intertemporal choice task and dot probe task first and then a cue-target task a week later. The results showed that the participants with low trait self-control were more likely to choose immediate rewards than participants with high trait self-control. Furthermore, facilitated attention and difficulty in attention disengagement toward present-related words were found among participants with low trait self-control with higher frequency than among those with high trait self-control. Finally, facilitated attention toward present-related words moderated the indifference points among the participants with low trait self-control.
