Putting the lie on the control condition for moral responsibility

In “Control, Responsibility, and Moral Assessment” Angela Smith defends her nonvoluntarist theory of moral responsibility against the charge that any such view is shallow because it cannot capture the depth of judgments of responsibility. Only voluntarist positions can do this since only voluntarist positions allow for control. I argue that Smith is able to deflect the voluntarists’ criticism, but only with further resources. As a voluntarist, I also concede that Smith’s thesis has force, and I close with a compromise position, one that allows for direct moral responsibility for the nonvoluntary, but also incorporates a reasonable control condition.

Is the principle of minimization of secondary moments validated during various fingertip force production conditions?

During the application of fingertip forces with simultaneous flexion of the four fingers, namely index, middle, ring, and little fingers, a stable force sharing among fingers is adopted. Several studies have hypothesized that this stable force sharing is established to minimize unnecessary rotational moments (different from the main flexion moments). This principle labeled "minimization of secondary moments" is presented in the literature as a principle used by the central nervous system to solve musculoskeletal redundancy. However, this principle has only been tested with one solicited degree of freedom and in one finger posture. Our study tests this principle with various degrees of freedom solicited as secondary moments and in two different finger postures. Participants (n=6) were asked to apply a downward vertical force using their four fingers with the forearm placed in two different configurations: a "horizontal" condition (involving flexion/extension and pronation/supination at the wrist joint) and a "vertical" condition (involving flexion/extension and radial/ulnar deviation at the wrist joint). Additionally, two finger postures were tested in each forearm configuration: in the first, the distal inter-phalangeal joints (DIP) were extended and the proximal inter-phalangeal joints (PIP) highly flexed. In the second finger posture, both DIP and PIP joints were flexed. The resultant four-finger force and the relative involvement of each finger in the resultant four-finger force (force sharing) were analyzed. Results showed that the finger postures did not influence the finger force sharing, showing that the minimization of the secondary moment principle was stable among the finger joint angle configurations. Nonetheless, the relative involvement of each finger was dependent on the secondary degree of freedom solicited (pronation/supination vs. radial/ulnar). The modifications of the finger force sharing between the "horizontal" and "vertical" conditions were in accordance with the principle of minimization of the secondary moments.     

大学生择业控制点的结构及现状分析

尝试建立择业控制点的内部-外部两维结构,并以此为基础了解当代大学生择业控制点现状。被试为石家庄的507名理工科大学生。验证性因素分析结果表明,择业两维控制点模型的数据拟合达到优良水平,提示内部、外部控制点可能不是一个连续体的两极;此外,择业控制点6个测量指标(其中专业能力、个人努力和选择能力为内部指标;专业运气、关系依赖和性别依赖为外部指标)的数据结果显示,高校学生的择业普遍存在外控特点,提醒高校应当对学生及早进行职业指导,强化学生对自身择业的责任感。     

Automatic goal inferences

The social psychological literature on automatic social inferences has focused on one construct that helps explaining human behavior—traits (e.g., Gilbert, Pelham, & Krull, 1988; Trope, 1986; Winter & Uleman, 1984). The dispositional roots of behavior, however, go beyond relatively stable constructs such as traits to include more transient causes such as one’s intentions and goals. Evidence from young infants and adult chimpanzees, knowledge acquired in the text-comprehension literature and hypotheses derived from the Automatic Causal Inferences framework (Hassin, Bargh, & Uleman, 2002), seems to converge: they all suggest that perceivers may automatically infer goals from behaviors. This paper reports four studies that examine this hypothesis. The first two use surprise cued-recall, and look at goal inferences when the road to goal achievement seems straightforward and when it seems blocked. Studies 3 and 4 use on-line methodologies—probe recognition task and lexical decision—to examine whether these inferences are made at encoding.     

为什么会出现“舌尖现象”?——TOT现象发生机制之争

舌尖现象(tip-of-the-tongue,TOT)是一种普遍发生的现象,但是发生TOT的对象、情景、机制等却是特殊和复杂的。因此,它引起了研究者的关注,尤其是在其产生机制上更是存在着很多争论。国外研究者提出了部分激活理论、传递缺陷理论、障碍物假说、神经网络模型、元认知理论等。但研究者大多都基于单一条件或情景来探讨TOT的产生,因此提出的理论的使用范围,解释广度等均有局限。关于TOT依然有许多疑惑,同时也存在值得探讨的课题。     

Causality orientations moderate the undermining effect of rewards on intrinsic motivation

The present study tested the hypothesis that individual differences in autonomy or control causality orientation would moderate the undermining effect of rewards on intrinsic motivation. Equal numbers of autonomy- and control-orientated participants provided solutions to an interesting puzzle under reward or no reward conditions. Participants were then required to provide further solutions to the puzzle in a free-choice period. The time spent in solving the puzzle during the free-choice period constituted the dependent measure of intrinsic motivation. Results revealed a significant interaction effect of causality orientations and reward condition on intrinsic motivation. Control-oriented participants assigned to the reward condition exhibited significantly lower levels of intrinsic motivation compared to those assigned to the no reward condition. In contrast, there was no significant difference in intrinsic motivation levels across the reward conditions for autonomy-oriented individuals. Findings indicate that an autonomy-oriented causality orientation offered a degree of ‘protection’ from the undermining effect of rewards on intrinsic motivation. This is in keeping with self-determination theory in terms of the interactive effects of environmental events and interpersonal factors on intrinsic motivation.     

When ostracism leads to aggression: The moderating effects of control deprivation

We hypothesized that increasing or decreasing levels of control in an ostracized individual could moderate aggressive responding to ostracism. Participants were either ostracized or included in a spontaneous game of toss, and then exposed to a series of blasts of aversive noise, the onsets over which they had either control or no control. Aggression was defined as the amount of hot sauce participants allocated to a stranger, knowing the stranger did not like hot foods, but would have to consume the entire sample. Ostracized participants without control allocated more than four times as much sauce as any other group; ostracized participants who experienced restored control were no more aggressive than either of the groups who were included. Aggressive responding to ostracism may depend on the degree to which control needs are threatened in the target, and is discussed in terms of Williams’s (2001) needs threat model of ostracism.     

Effects of vision and cognitive load on anticipatory and compensatory postural control

This study assessed the effects of vision and cognitive load on anticipatory postural adjustments (APAs) and compensatory postural adjustments (CPAs) in response to an externally triggered postural perturbation. A ball-hitting test was repeated under different visual conditions (eyes open, EO; eyes closed, EC) and cognitive loads (no load, 3-subtraction task, time-limited 3-subtraction task). Data were collected separately for I) surface electromyography from the right side of the biceps brachii (BIC) and erector spinae (ES) to detect the latency and response intensity (RI); and II) displacement of the centre of pressure (ΔCOP) to detect the standard deviation (ΔCOP_SD) and maximum value (ΔCOP_max) in the anterior-posterior direction. Compared with the results under the EC condition, the ES latency was shorter and the RI of the BIC was lower under the EO condition. Accordingly, the ΔCOP_SD and ΔCOP_max were increased in the APAs phase and decreased in the CPAs phase. Cognitive load had no effect on APAs and CPAs or on ΔCOP in the APAs phase. However, ΔCOP_max was decreased in the CPAs phase during the EC condition. In conclusion, vision played an important role in APAs and CPAs for muscle activation and ΔCOP. Cognitive load had no effect on neuromuscular APAs or CPAs except when the postural perturbation occurred when visually unexpected.

Maintaining perceived control with unemployment facilitates future adjustment

Unemployment is a major challenge to individuals' development. An important personal resource to ameliorate the negative impact of unemployment may be perceived control, a general-purpose belief system. Little is known, however, about how perceived control itself changes with the experience of unemployment and what the antecedents, correlates, and consequences of such change in perceived control are in different ages. We use data from the German Socio-Economic Panel Study (N = 413 who experienced unemployment and N = 413 case-matched controls; time period of data collection: 1994–1996) to examine whether perceived control changes with unemployment, explore the role of socio-demographic, psychosocial and health factors in moderating such change, and investigate whether levels of perceived control prior to unemployment and unemployment-related change in perceived control predict unemployment-related outcomes up to five years following. Results indicated that, on average, perceived control remained relatively stable with unemployment, and that younger and older workers did not differ in this regard. However, there were sizeable individual differences in change in perceived control, with women and those with fewer years of education experiencing greater unemployment-related declines in perceived control. Lower levels of perceived control prior to unemployment and steeper unemployment-related decrements in perceived control were each associated with a higher risk of remaining unemployed in the 12 months immediately following unemployment. Steeper unemployment-related declines in perceived control also predicted lower life satisfaction up to five years following. We discuss possible pathways by which perceived control may facilitate adjustment to unemployment, consider the role of perceived control for better understanding the dynamics of unemployment, and suggest routes for further more process-oriented inquiry.
