When planning is not enough: Fighting unhealthy snacking habits by mental contrasting with implementation intentions (MCII)

In two experiments a self‐regulatory strategy combining mental contrasting with the formation of implementation intentions (MCII) was tested for its effectiveness in diminishing unhealthy snacking habits. Study 1 (N = 51) showed that participants in the MCII condition consumed fewer unhealthy snacks than participants in a control condition who thought about and listed healthy options for snacks. In Study 2 (N = 59) MCII was more effective than mental contrasting or formulating implementation intentions alone and mental contrasting was found to increase perceived clarity about critical cues for unhealthy snacking. Together, these findings suggest that MCII is an effective strategy for fighting habits and that one of the underlying processes making MCII superior to implementation intentions alone may be that mental contrasting produces clarity about the critical cues for the unwanted habitual behavior.

Spinozistic Pantheism,the Environment and Christianity

I am not a pantheist and I don’t believe that pantheism is consistent with Christianity. My preferred speculation is what I call the Swiss Cheese theory: we and our artefacts are the holes in God, the only Godless parts of reality. In this paper, I begin by considering a world rather like ours but without any beings capable of sin. Ignoring extraterrestrials and angels we could consider the world, say, 5 million years ago. Pantheism was, I say, true at that time. That is my qualified endorsement of pantheism. I then use the Sin premise, namely that we are capable of sinning, to argue that beings like us are not parts of God and I examine some consequences.

Is prospective memory related to depression and anxiety? A hierarchical MPT modelling approach

Prospective memory (PM) refers to remembering to perform an action in the future. One hundred and twenty-nine students completed a laboratory event–based PM task as well as depression and anxiety questionnaires. The data were analysed with the beta-MPT version of the multinomial processing tree model of event-based PM. Thereby, the prospective and retrospective components of PM were estimated for each participant and were then correlated with depression and anxiety. State anxiety was negatively correlated with the prospective component of PM. Neither depression nor trait anxiety were related to either component of PM.     

A sub-process view of working memory capacity: Evidence from effects of speech on prose memory

In this article we outline a “sub-process view” of working memory capacity (WMC). This view suggests that any relationship between WMC and another construct (e.g., reading comprehension) is actually a relationship with a specific part of the WMC construct. The parts, called sub-processes, are functionally distinct and can be measured by intrusion errors in WMC tasks. Since the sub-processes are functionally distinct, some sub-process may be related to a certain phenomenon, whereas another sub-process is related to other phenomena. In two experiments we show that a sub-process (measured by immediate/current-list intrusions) is related to the effects of speech on prose memory (semantic auditory distraction), whereas another sub-process (measured by delayed/prior-list intrusions), known for its contribution to reading comprehension, is not. In Experiment 2 we developed a new WMC task called “size-comparison span” and found that the relationship between WMC and semantic auditory distraction is actually a relationship with a sub-process measured by current-list intrusions in our new task.     

Mathematical constraints and the tulving-wiseman law: A Rejoinder

Abstract

Hintzman (1991; 1992) has claimed that the reason data points approximate the recognition failure function discovered by Tulving and Wiseman (1975) is that they are mathematically constrained to do so, and the reason that a few data points do not approximate the function, but are exceptions to it, is that these data points are less subject to mathematical constraints. He has additionally argued that such exceptions are more likely with low levels of recall and strong underlying sources of positive covariance. We provide empirical evidence relevant to this mathematical model using 301 observations from a database of all relevant experimental conditions published between 1973 and 1992 (Nilsson & Gardiner, 1993). We conclude that mathematical constraints have only a minor influence on the function, not the causal role assigned to them in Hintzman's (1992) model. By our account, both the function and exceptions to it reflect a single psychological principle, the functional effectiveness of contextual cues.     

Whose Fault? The Origins and Evitability of the Analytic–Continental Rift

This is a broad survey of the chronology of the rift between continental and analytic philosophy, starting in 1899. Whereas at that time there was no discernible divide, as the twentieth century progresses we can see a gradual parting of the ways in which philosophy was done, culminating in a period of maximum separation in 1945-68, followed by some convergence. There is one substantial historical thesis proposed, and facts are adduced from the chronology to back it up: that the divide was never absolute, never purely geographical, and above all that it was not inevitable, but was largely the product of accidental historical circumstances, of which the most crucial was the flourishing of totalitarianism in Europe and the disruption caused by two world wars.     

Scientific Discovery With Law-Encoding Diagrams

This article introduces the concept of law-encoding diagrams (LEDs) and presents the argument that they have had a role in scientific discovery that has not been previously recognized. An LED is a representation that correctly encodes the underlying relations of a law, or a system of simultaneous laws, in the structure of a diagram by the means of geometric, topological, and spatial constraints, such that the instantiation of a particular diagram represents a single instance of the phenomena or a particular case of the law(s). Examples of LEDs in the history of science are discussed, and the benefits of using LEDs in discovery are considered. LEDs are distinguished from other forms of diagrammatic representation. Previous work on the computational modeling of diagrammatic law induction is reinterpreted in terms of the search for diagrammatic constraints of LEDs. A general characterization of the role of LEDs in discovery is considered, and a framework for classifying processes of discovery based on LEDs is proposed.     

Thinking Outside the Square: Business Students' Conceptions of Creativity

Creativity is an important attribute of a successful graduate of higher education, recognised by universities and employers alike. In this paper, we investigate ideas about creativity that were discussed during interviews by a group of business students at a university in Sydney, Australia. Using a phenomenographic approach, we identified three levels of conceptions of creativity, labeled Definition, Attribute, and Comprehensive, from the narrowest and most limited to the broadest and most inclusive. We discuss the characteristics of these different ways of viewing creativity and the pedagogical implications of our findings for business education (and higher education generally).
