Guest Editorial: Who's Afraid of Life After Death?

The evidence for an afterlife is sufficiently strong and compelling that an unbiased person ought to conclude that materialism is a false theory. Yet the academy refuses to examine the evidence, and clings to materialism as if it were a priori true, instead of a posteriori false. I suggest several explanations for the monumental failure of curiosity on the part of academia. First, there is deep confusion between the concepts of evidence and proof. Second, materialism functions as a powerful paradigm that structures the shape of scientific explanations, but is not itself open to question. The third explanation is intellectual arrogance, as the possible existence of disembodied intelligence threatens the materialistic belief that the educated human brain is the highest form of intelligence in existence. Finally, there is a social taboo against belief in an afterlife, as our whole way of life is predicated on materialism and might collapse if near-death experiences, particularly the life review, were accepted as fact.     

Prosocial behavior in families: Moderators of resource sharing

Archival studies of within-family prosocial behavior (Judge & Hrdy, 1992; Smith, Kish, & Crawford, 1987) have shown that inheritance patterns support Hamilton’s (1964) theory of inclusive fitness, such that people will more of their estates to relatives of closer genetic relatedness. In a survey-based simulation of these studies, students allocated one of three lotteries to their blood relatives. As expected, participants allocated greater proportions of their lotteries to relatives of greater genetic relatedness. This effect became stronger with decreasing lottery amounts. Relatives of certain relatedness were favored over relatives of uncertain relatedness (via paternal uncertainty), and this effect was stronger among those with less money to allocate. Male participants tended to favor their young female relatives over their young male relatives when given the smallest lottery, but this sex preference reversed when male participants were given the largest lottery. In general, scarcer resources led to more evolutionarily conservative investment strategies.     

浅析心电波形唯一性假说

通过对海量心电图资料的分析，发现每个人的心电图波形绝然不同，均有其自身特点，也即具有唯一性，而同一人的心电波形在出生后至18岁成年前如人的容貌、身高、体重一样变化较大，成年后则相对稳定、基本不变，我们认为心电波形如同其他生物特征一样具有生物特征的显著特点，由此提出心电图心电波形具有唯一性的假说。     

Contextual information influences the feeling of knowing in episodic memory

The feeling of knowing (FOK) predicts the likelihood of eventually recognizing currently unrecalled items. Koriat (1993, 1995) showed that retrieval of partial target information influences FOK ratings. Building on Koriat’s view, the noncriterial-recollection hypothesis contends that contextual information influences FOKs (Brewer, Marsh, Clark-Foos, & Meeks, 2010). Our study assessed the validity of the noncriterial-recollection hypothesis by controlling the amount of potentially-retrievable contextual information presented to participants. We varied the amount of contextual information accompanying the name and image of imaginary animals. There were three information conditions: minimum (name and image), medium (name, image, and country), and maximum (name, image, country, diet and weight). Information condition did not affect recall accuracy. The minimum condition resulted in greater response output (recall and commission errors together). FOKs for unrecalled items were lower in the minimum condition than the other conditions. Consistent with the noncriterial-recollection hypothesis, FOKs were positively correlated with the retrieval of contextual information.     

Probabilities,causation, and logic programming in conditional reasoning: reply to Stenning and Van Lambalgen (2016)

Oaksford and Chater (2014 Oaksford, M., &; Chater, N. (2014). Probabilistic single function dual process theory and logic programming as approaches to non-monotonicity in human vs. artificial reasoning. Thinking and Reasoning, 20, 269–295. doi:10.1080/13546783.2013.877401[Taylor &; Francis Online], [Web of Science ®] , [Google Scholar], Thinking and Reasoning, 20, 269–295) critiqued the logic programming (LP) approach to nonmonotonicity and proposed that a Bayesian probabilistic approach to conditional reasoning provided a more empirically adequate theory. The current paper is a reply to Stenning and van Lambalgen's rejoinder to this earlier paper entitled ‘Logic programming, probability, and two-system accounts of reasoning: a rejoinder to Oaksford and Chater’ (2016) in Thinking and Reasoning. It is argued that causation is basic in human cognition and that explaining how abnormality lists are created in LP requires causal models. Each specific rejoinder to the original critique is then addressed. While many areas of agreement are identified, with respect to the key differences, it is concluded the current evidence favours the Bayesian approach, at least for the moment.     

Cultural transmission through infant signs: Objects and actions in U.S. and Taiwan

Infant signs are intentionally taught/learned symbolic gestures which can be used to represent objects, actions, requests, and mental state. Through infant signs, parents and infants begin to communicate specific concepts earlier than children’s first spoken language. This study examines whether cultural differences in language are reflected in children’s and parents’ use of infant signs. Parents speaking East Asian languages with their children utilize verbs more often than do English-speaking mothers; and compared to their English-learning peers, Chinese children are more likely to learn verbs as they first acquire spoken words. By comparing parents’ and infants’ use of infant signs in the U.S. and Taiwan, we investigate cultural differences of noun/object versus verb/action bias before children’s first language. Parents reported their own and their children's use of first infant signs retrospectively. Results show that cultural differences in parents’ and children’s infant sign use were consistent with research on early words, reflecting cultural differences in communication functions (referential versus regulatory) and child-rearing goals (independent versus interdependent). The current study provides evidence that intergenerational transmission of culture through symbols begins prior to oral language.     

Unintentional movements induced by sequential transient perturbations in a multi-joint positional task

We explored the phenomenon of unintentional movements of a multi-joint effector produced by multiple transient changes in the external force. The subjects performed a position-holding task against a constant bias force produced by a robot and were instructed not to intervene voluntarily with arm movements produced by changes in the robot force. The robot produced a smooth force increase leading to hand movement from the trunk, followed by a dwell time. Then, the force dropped to its initial value leading to hand movement toward the initial position but with an undershot. Such perturbation episodes were repeated four times in a row. The accumulated perturbation and undershoot distances kept increasing without saturation within the sequence of four perturbation episode. The limb apparent stiffness before dwell time increased over sequential perturbations while apparent stiffness after dwell time decreased. We interpret the results as consequences of a drift of the hand referent coordinate (RC) caused by a hypothesized RC-back-coupling mechanism and a coupled drift of the apparent stiffness. The results show that RC-back-coupling continues to lead to unintentional movements over repeated perturbations and is accompanied by a relatively slow re-setting process.     

Blame Game and Rotten Apples in Private Investigation Reports: The Case of Hadeland and Ringerike Broadband in Norway

Blame game is a term often used to describe a phenomenon that happens in groups of people when something goes wrong. The blame game hypothesis postulates that private investigators may be misled in their search for suspects and that suspected individuals do not necessarily become subject to a fair investigation by financial crime specialists and fraud examiners. The rotten apple hypothesis postulates that it is comforting to assume that one bad apple within an organisation is essentially responsible for the crime that is all too prevalent. The rotten apple view of white‐collar crime is a comfortable perspective to apply to business and public organisations as it allows them to look no further than suspect a single individual. Based on a case study of the Norwegian company Hadeland and Ringerike Broadband, this paper discusses blame game and rotten apple issues in an internal investigation report written by an external financial crime specialist. The study finds support for both hypotheses, as blame is mainly isolated to the criminal and his superior, and both board and top management are protected from scrutiny.

关于假设检验的争议:问题的澄清与解决

对传统的假设检验作为心理学实验的数据分析工具的评价涉及两个标准:首先是它是否合法,其次是它是否有用。置于频率学派统计学框架中的传统假设检验在逻辑上实际上是合法的;但它在效用性方面则有着备择假设不可证伪以及只能提供定性结论这两方面的缺陷。置信区间能够集中地改进和弥补这些缺陷。对传统假设检验使用中错误的澄清也使得研究者们开始重视PSI问题,这使得心理学实验的设计和数据分析从关注总体转向关注个体。
