Power gained,power lost

Changes in power almost invariably lead to changes in behavior. This research investigates the effects of power increases and power decreases for individuals who are in strong or weak positions. We hypothesized that individuals will have strong reactions to gains in power (their demands will increase markedly) but they will act almost as though they do not recognize losses in power (their demands will not drop much) when they lose power. Four experiments track individuals’ actions when they move from ultimatum to dictatorship games, from dictatorship to ultimatum games, or when they have the same power position repeatedly. The data consistently show that people over-react to an increase in power, but that they react appropriately to a loss in power. The discussion explores the behavioral disconnect between increases and decreases in power.     

Control,responsibility, and moral assessment

Recently, a number of philosophers have begun to question the commonly held view that choice or voluntary control is a precondition of moral responsibility. According to these philosophers, what really matters in determining a person’s responsibility for some thing is whether that thing can be seen as indicative or expressive of her judgments, values, or normative commitments. Such accounts might therefore be understood as updated versions of what Susan Wolf has called “real self views,” insofar as they attempt to ground an agent’s responsibility for her actions and attitudes in the fact (when it is a fact) that they express who she is as a moral agent. As such, they seem to be open to some of the same objections Wolf originally raised to such accounts, and in particular to the objection that they cannot license the sorts of robust moral assessments involved in our current practices of moral responsibility. My aim in this paper is to try to respond to this challenge, by clarifying the kind of robust moral assessments I take to be licensed by (at least some) non-volitional accounts of responsibility and by explaining why these assessments do not in general require the agent to have voluntary control over everything for which she is held responsible. I also argue that the limited applicability of the distinction between “bad agents” and “blameworthy agents” on these accounts is in fact a mark in their favor.

Coherence and recurrency: maintenance,control and integration in working memory

Working memory (WM), including a ‘central executive’, is used to guide behavior by internal goals or intentions. We suggest that WM is best described as a set of three interdependent functions which are implemented in the prefrontal cortex (PFC). These functions are maintenance, control of attention and integration. A model for the maintenance function is presented, and we will argue that this model can be extended to incorporate the other functions as well. Maintenance is the capacity to briefly maintain information in the absence of corresponding input, and even in the face of distracting information. We will argue that maintenance is based on recurrent loops between PFC and posterior parts of the brain, and probably within PFC as well. In these loops information can be held temporarily in an active form. We show that a model based on these structural ideas is capable of maintaining a limited number of neural patterns. Not the size, but the coherence of patterns (i.e., a chunking principle based on synchronous firing of interconnected cell assemblies) determines the maintenance capacity. A mechanism that optimizes coherent pattern segregation, also poses a limit to the number of assemblies (about four) that can concurrently reverberate. Top-down attentional control (in perception, action and memory retrieval) can be modelled by the modulation and re-entry of top-down information to posterior parts of the brain. Hierarchically organized modules in PFC create the possibility for information integration. We argue that large-scale multimodal integration of information creates an ‘episodic buffer’, and may even suffice for implementing a central executive.     

Job-seeking and job-acquisition in high school students

We surveyed 225 Year 9 and 10 students at T1 regarding their attitude, social norms, control, experience, plans and intentions to find a part-time job while at school. Of these, 149 did not have a job and were surveyed again four months later about their job-seeking and job outcomes (104 responded at T2). Job-seeking intentions at T1 were associated with past experience, plans and beliefs that getting a job was the right thing to do. Job-seeking at T2 was associated with beliefs about the value of job-seeking. Job interviews attended were related to job-seeking, and job offers were related to interviews attended. Students with higher job-seeking intentions and behaviours differed on most variables from students with lower intentions and behaviours. Students need to be aware of the relationship between job-seeking, interviews and offers, and be provided with strategies that increase their interviews and assist to manage unsuccessful job attempts.     

Work, family and life-course fit: Does control over work time matter?

This study moves from “work-family” to a multi-dimensional “life-course fit” construct (employees’ cognitive assessments of resources, resource deficits, and resource demands), using a combined work-family, demands-control and ecology of the life course framing. It examined (1) impacts of job and home ecological systems on fit dimensions, and (2) whether control over work time predicted and mediated life-course fit outcomes. Using cluster analysis of survey data on a sample of 917 white-collar employees from Best Buy headquarters, we identified four job ecologies (corresponding to the job demands-job control model) and five home ecologies (theorizing an analogous home demands-home control model). Job and home ecologies predicted fit dimensions in an additive, not interactive, fashion. Employees’ work-time control predicted every life-course fit dimension and partially mediated effects of job ecologies, organizational tenure, and job category.     

MMCS的心理测量学性能及中国大学生心理控制源的特点

以某民族大学的2006级学生为被试探讨了MMCS量表的心理测量学性能。结果表明MMCS的信度与国外基本相同,验证性因素分析发现在分解出正向和反向陈述效应后MMCS呈现出较好的模型拟合度。对MMCS的8个分量表总分所做的因素分析发现了清晰的因素结构,与理论假设非常符合。这些结果说明中国人也存在内外控的心理结构。但不同的是中国被试中内控和外控并不是相互独立的,也不是对立的两极,而是相关的,且表现出内控强于外控的倾向。通过与症状自评量表SCL-90的相关分析发现外控是不利于心理健康的,过强的内控也不好,而既不过分外控也不过分内控的适度控制方式可能是中国文化背景下最理想的心理控制方式。     

Measuring Theodicy: Individual Differences in the Perception of Divine Intervention

The attribution of control to God may have particularly interesting psychological properties. Theodicy refers to the perception of God controlling history—even the minutiae of daily events. The current study examines the psychometric properties of a new instrument, the Theodicy Scale. Results support the reliability of the brief scale when administered to college students, and some evidence is provided suggesting construct validation. Theodicy appears to represent a unitary construct and scores vary independent of social desirability bias. The absence of a relationship between Theodicy scores and simulated medical advice raises questions to be addressed in future research.     

The memorizing effort heuristic in judgments of learning: A developmental perspective

Recent work on adult metacognition indicates that although metacognitive monitoring often guides control operations, sometimes it follows control operations and is based on the feedback from them. Consistent with this view, in self-paced learning, judgments of learning (JOLs) made at the end of each study trial decreased with the amount of time spent studying the item, suggesting that JOLs are based on the memorizing effort heuristic that easily learned items are more likely to be remembered. Study 1 extended investigation to primary school children. Whereas for third to sixth graders (9- to 12-year-olds) JOLs decreased with increasing study time (ST), no such relationship was found for first and second graders (7- and 8-year-olds). For both age groups, however, recall decreased with ST, supporting the validity of the memorizing effort heuristic. Self-reports (Study 2) disclosed the belief that recall should tend to increase with ST. The results bring to the fore the importance of mnemonic cues that shape metacognitive feelings even among primary school children. These cues lie in the very feedback that learners gain on-line from task performance rather than in metacognitive knowledge, and their use may also contribute to increased monitoring accuracy with age.     

Specific effects of acute moderate exercise on cognitive control

The main issue of this study was to determine whether cognitive control is affected by acute moderate exercise. Twelve participants [4 females (VO_{2 max} = 42 ml/kg/min) and 8 males (VO_{2 max} = 48 ml/kg/min)] performed a Simon task while cycling at a carefully controlled workload intensity corresponding to their individual ventilatory threshold. The distribution-analytical technique and the delta plot analysis [Ridderinkhof, K. R. (2002). Activation and suppression in conflict tasks: Empirical clarification through distributional analyses. In W. Prinz & B. Hommel (Eds.), Common mechanisms in perception and action. Attention and performance (Vol. 19, pp. 494–519). Oxford: Oxford University Press.] were used to assess the role of selective response inhibition in resolving response conflict. Results showed that cognitive processes appeared to be differently affected by acute moderate exercise. Reaction time results confirmed that performance is better (faster without change in accuracy) when the cognitive task is performed simultaneously with exercise. Between-trial adjustments (post-conflict and post-error) highlighted that cognitive control adjustments are also fully efficient during exercise. However, the effect of congruency (Simon effect) appeared to be more pronounced during exercise compared to rest which suggests that the response inhibition is deteriorated during exercise. The present findings suggest that acute moderate exercise differently affects some specific aspects of cognitive functions.
