抑制控制能力衰退对知觉组织老年化的影响

通过比较注意线索对老年人和年轻人共线性和相似性知觉组织的影响,探讨了知觉组织老年化的原因。研究发现,注意线索对年轻人的助益更大,对老年人的助益较小,符合抑制控制理论的研究假设,同时本文还对加工速度、基本感觉能力等可能引起认知老年化的因素进行了分析。此外,还发现了知觉组织中与阅读习惯一致的方向偏好,无论在有无注意线索的条件下,135°方向上的知觉组织都快于45°方向上的知觉组织。     

Fitting Attitudes, Welfare, and Time

Chris Heathwood has recently put forward a novel and ingenious argument against the view that intrinsic value is analyzable in terms of fitting attitudes. According to Heathwood, this view holds water only if the related but distinct concept of welfare—intrinsic value for a person—can be analyzed in terms of fitting attitudes too. Moreover, he argues against such an analysis of welfare by appealing to the rationality of our bias towards the future. In this paper, I argue that so long as we keep the tenses and the intrinsic/extrinsic distinction right, the fitting-attitudes analysis of welfare can be shown to survive Heathwood’s criticism.

排除“每个人都优于平均水平”机制影响的自我提升研究

采用优于平均效应、自我服务归因偏向和内隐测验三种方法测量中国大学生的自我提升,并在前两种方法中考虑了EBTA机制的影响,以探讨中国人的自我提升动机及其表现形式。结果发现：EBTA机制影响显著;排除EBTA机制的影响后,大学生依然存在优于平均效应和自我服务归因偏向;大学生存在内隐自我提升值;内隐自我提升值与外显自我提升值之间存在显著正相关。     

Canceling out both the real and the spectral lines

Neglect patients typically show motor perseveration while canceling targets on the ipsilesional side. This behavior can be influenced by the presence vs. absence of targets on the (neglected) contralesional side (). As alternative explanations, the authors proposed (i) directional hypokinesia--the patient cannot perform reaching movements towards detected left-sided targets, and thus carries on canceling on the right side, and (ii) allochiria--the patient misperceives left-sided targets as located on the right side, and cancels them there. We report here data from a patient (EZ) that might confirm the second hypothesis. EZ was presented with 19 displays in which the number and position of cancellation targets on both sides were varied systematically. EZ showed motor perseveration while canceling, but this tendency did not vary across conditions. Interestingly though, EZ also drew cancellation marks in the empty space between the ipsilesional targets, and this phenomenon was significantly more intense when there were more targets on the neglected side. As EZ's comments suggested, such a behavior might reflect the attempt to cancel out delusional targets. Our speculation is that those objects were generated by allochiria.     

Nozick's experience machine is dead,long live the experience machine!

Robert Nozick's experience machine thought experiment (Nozick's scenario) is widely used as the basis for a “knockdown” argument against all internalist mental state theories of well-being. Recently, however, it has been convincingly argued that Nozick's scenario should not be used in this way because it elicits judgments marred by status quo bias and other irrelevant factors. These arguments all include alternate experience machine thought experiments, but these scenarios also elicit judgments marred by status quo bias and other irrelevant factors. In this paper, several experiments are conducted in order to create and test a relatively bias-free experience machine scenario. It is argued that if an experience machine thought experiment is used to evaluate internalist mental state theories of well-being, then this relatively bias-free scenario should be used over any of the existing scenarios. Unlike the existing experience machine scenarios, when this new scenario is used to assess internalist mental state theories of well-being, it does not provide strong evidence to refute or endorse them.

Finishing on time: When do predictions influence completion times?

People typically predict they will finish projects earlier than they do. Whereas previous research has examined the determinants of this prediction bias, the present research explored potential consequences for behavior. In particular, we examined whether and when task completion predictions influence actual completion times. In four experiments we used anchoring manipulations to induce participants to make relatively early or late task completion predictions, and then examined when they started and/or finished the target tasks. As hypothesized, the prediction manipulation influenced completion times under certain conditions defined by the nature of the target task. Manipulated predictions affected completion times of closed tasks, defined as tasks carried out within a single, continuous session but not of open tasks, defined as tasks requiring multiple work sessions. This implies that task completion predictions help to initiate action, but their impact diminishes over the course of extensive, multi-stage projects.     

Metacognition and emotion – How accurate perception of own biases relates to positive feelings and hedonic capacity

Metacognition refers to awareness of one’s own cognitive processes, including examining own biases and decision making. Metacognitive self (MCS), defined as accuracy in perception of own biases, is associated with pro-health behaviors and desire for feedback, including negative information.Two studies investigated MCS in relation to emotion and hedonic capacity. First, in a longitudinal study of college students, MCS measure was stable over time, and correlated with feelings of love and joy. In the second study, MCS, mood, and hedonic capacity ratings were collected prior to evaluating stimuli for pleasure from engagement during an fMRI. Higher MCS was associated with greater hedonic capacity and increased signal in cortical areas involved in self-reflection and decision making.Our findings implicate self-awareness of biases as a cognitive process supporting positive emotional state and hedonic capacity. Future studies should explore how MCS relates to changes in mood and vulnerability to mood disorders.
