Nonhuman rationality: a predictive coding perspective

Cognitive Processing - How can we rethink ‘rationality’ in the wake of animal and artificial intelligence studies? Can nonhuman systems be rational in any nontrivial sense? In this...     

The early Yogācāra theory of no-self

ABSTRACT

I reconstruct early Yogācāra theory of no-self based on works by Asa?ga and Vasubandhu. I introduce the idea of the cognitive schema (CS) of the self, a conception borrowed from the developmental psychologist, Jean Piaget. A fundamental CS is a psychological function that guides the formation of perceptions. I propose that Manas can be understood in terms of being the CS of the self, a psychological mechanism from which perceptions of external objects are formed. In addition, I argue that non-imaginative wisdom can be regarded as an experience during which the CS of the self does not function, such that one only possesses pure sensations without perceptions of external objects. After the repeated experience of non-imaginative wisdom, the CS of the self is changed to the purified CS of no-self. It still supports interactions with the external world, but in a way that does not allow the four afflictions (self-delusion, self-belief, self-conceit, and self-love) to arise.

The relative influence of conduct problems and attention-deficit hyperactivity disorder in the development of adolescent psychopathy

An in depth literature review was conducted into the relative influence of conduct problems and attention-deficit hyperactivity disorder in the development of child/adolescent psychopathy. Lynam (1996) wrote that children/adolescents exhibiting behaviors of both were ‘fledgling psychopaths;’ however, recent evidence suggests that if youth with comorbid conduct problems and ADHD exhibit a persistent form of antisocial and/or psychopathic behavior, the cause is primarily due to the levels of conduct problems, not the influence of ADHD. This article looks at the three perspectives regarding the development of psychopathy: (1) Conduct Problem Mediation, (2) the Independent Position, and (3) the Comorbid Subtype. The studies examining the three perspectives found that the Conduct Problem Mediation, not the Comorbid Subtype, was the most important in the development of psychopathy.     

Delinquency in gangs — Selection or socialization?

Thornberry, Krohn, Lizotte, and Chard-Wierschem's (1993) introduced three models to account for why gangs are associated with high levels of delinquency. Existing research using Thornberry et al.'s (1993) models to explain the gang-delinquency association has been inconclusive. This paper seeks to address this gap in research by incorporating Moffitt's (1993) developmental taxonomy of delinquency within Thornberry et al.'s (1993) explanatory models. A few proposals are put forth in this paper: (1) support for Thornberry et al.'s (1993) models depends on developmental stage of the individual, (2) the selection model explains delinquency of life-course-persistent gang members, while social facilitation model explains delinquency of adolescence-limited gang members, and (3) support for the enhancement model is an artifact of assuming a homogenous gang sample.     

Formulation and Application of the Hierarchical Generalized Random-Situation Random-Weight MIRID

The process-component approach has become quite popular for examining many psychological concepts. A typical example is the model with internal restrictions on item difficulty (MIRID) described by Butter (1994) Butter, R. 1994. Item response models with internal restrictions on item difficulty, Doctoral thesis Leuven, , Belgium: Katholieke Universiteit..  [Google Scholar] and Butter, De Boeck, and Verhelst (1998). This study proposes a hierarchical generalized random-situation random-weight MIRID. The proposed model is more flexible for formulating endogenous latent variables within a multilevel framework, allowing the analysis of polytomous data with complex models (e.g., including item discriminations, random situations, random weights, and heteroskedasticity). The parameters in the proposed model can be estimated using the computer program WinBUGS, which adopts Markov Chain Monte Carlo algorithms. To illustrate the application of the proposed model, a real data set about guilt is analyzed and a comparison of MIRIDs for various conditions is conducted.     

Psychological contracts and innovative behavior: a moderated path analysis of work engagement and job resources

This study explored the relationships between psychological contract types and innovative behavior. We focused on the mediating effect of work engagement and the moderating effect of job resources (organizational and social resources). Participants were 267 dyads of research and development engineers and their supervisors from 30 high‐tech companies. Moderated path analysis was used to test the hypotheses. Findings showed that: (a) work engagement fully mediated the negative relationship between transactional contracts and innovative behavior; in addition, it also fully mediated the positive relationship between relational contracts and innovative behavior; and (b) job resources attenuated the former and strengthened the latter mediating effects. These findings contribute to understanding how, why, and when psychological contract types lead to innovative behavior via work engagement.     

Probabilities in implicit learning

The visual system possesses a remarkable ability in learning regularities from the environment. In the case of contextual cuing, predictive visual contexts such as spatial configurations are implicitly learned, retained, and used to facilitate visual search-all without one's subjective awareness and conscious effort. Here we investigated whether implicit learning and its facilitatory effects are sensitive to the statistical property of such implicit knowledge. In other words, are highly probable events learned better than less probable ones even when such learning is implicit? We systematically varied the frequencies of context repetition to alter the degrees of learning. Our results showed that search efficiency increased consistently as contextual probabilities increased. Thus, the visual contexts, along with their probability of occurrences, were both picked up by the visual system. Furthermore, even when the total number of exposures was held constant between each probability, the highest probability still enjoyed a greater cuing effect, suggesting that the temporal aspect of implicit learning is also an important factor to consider in addition to the effect of mere frequency. Together, these findings suggest that implicit learning, although bypassing observers' conscious encoding and retrieval effort, behaves much like explicit learning in the sense that its facilitatory effect also varies as a function of its associative strengths.     

An intermediary enhances out‐group trust and in‐group profit expectation of Chinese but not Australians

In this research, we made a theoretical distinction between direct and intermediary‐mediated trust situations, and conducted a cross‐cultural (Chinese vs. Australians) investment trust game to test the overlooked effects of an intermediary on investors' trust decisions, with respect to how much to invest in and expect from trustees. Compared to situations of direct trust, a nominal intermediary increased the number of Chinese investors expecting in‐group trustees to repay a profit on their investments (Hypothesis 1) and raised their level of investment in out‐group trustees (Hypothesis 2). These results applied to Chinese, but not Australians in support of the proposal that a nominal intermediary would serve as a cue to activate different cultural stereotypes of the functions and meanings of an intermediary with respect to trust and expectation of reciprocity. Coexisting with these culture‐specific effects of an intermediary, the minimal categorisation of people into in‐group and out‐group on trivial grounds leads to a highly significant in‐group favouritism in investment levels of both Chinese and Australians (Hypothesis 3).
