Framing human inference by coherence based probability logic

We take coherence based probability logic as the basic reference theory to model human deductive reasoning. The conditional and probabilistic argument forms are explored. We give a brief overview of recent developments of combining logic and probability in psychology. A study on conditional inferences illustrates our approach. First steps towards a process model of conditional inferences conclude the paper.     

Legitimating the legitimate: A grounded theory study of legitimacy work among Ethics and Compliance Officers

Organizations have responded to ethical scandals in part by creating the Ethics and Compliance Officer (ECO) role to help insure employee ethical and legal behavior. Because ECO work is so fundamental to behavioral ethics in organizations and we know very little about it, we conducted a grounded theory study to learn more. We learned that, although most ECOs were hired to help their organizations respond to external legitimacy challenges, ECOs face major legitimacy challenges inside their organizations. Facilitating conditions may reduce these challenges and help ECOs reach internal legitimacy. But, we also found that ECOs engage in what we term legitimacy work that relies on a number of tactics to help them gain legitimacy in the eyes of their constituents. We tie our findings to the broader legitimacy literature and draw implications for the behavioral ethics literature.     

A Comparison of Teacher and Parent Delivered Consequences: Improving Classroom Behavior in Low-Income Children with ADHD

Both teacher and parent delivered consequences have been shown to be effective in improving the classroom behavior of children with Attention Deficit Hyperactivity Disorder (ADHD). However, there is a delay between the behavior and delivery of parent provided consequences. The delay may make the consequences less salient and effective, for children with ADHD. The current study compared the effectiveness of parent delivered consequences (PC) to teacher delivered consequences (TC) for increasing academic performance and appropriate classroom behavior in African American, low income, elementary students with ADHD. Results indicate that the two interventions are equally effective in improving children's on-task behavior and classwork productivity.     

Personal project commitment in adolescence: The role of relatedness,competence and integrity

University (n = 175) and high school (n = 162) students rated their commitment to three personal projects self‐identified as central to their lives, the extent to which each project generated experiences of relatedness, competence and integrity, and how much approval it received from significant others. This study compared the ‘life’ (hobbies, fitness, church, life transitions, intrapersonal, etc.) and education projects of participants who spontaneously generated an example of each (98 university and 70 high school participants). Integrity and competence received higher ratings than relatedness and were the most important predictors of commitment to both types of project. For both groups, education projects received more family/adult approval than life projects and there was much greater variation in approval ratings for the latter. The results suggest that, at least for young people in New Zealand, feeling that you are good at a project and it fits with your values, is almost a proxy for commitment. It is possible that social factors play a less direct role, perhaps by influencing the choice of interpersonal settings in which to carry out important projects.

Personality Preferences and Their Relationship to Ego Development in Australian Leadership Program Participants

The growth of adult ego development to post-conventional levels is associated with many adaptive advantages for the individual and society. However, the vast majority of adults across a wide range of samples demonstrate ego stages well below the maximum potential. In an effort to advance understanding of why and how development to higher ego levels might occur for some individuals and not others, we explored whether particular personality preferences and combinations thereof (as measured by the Myers-Briggs Type Indicator or MBTI) are associated with higher ego levels and whether particular personality preferences might act as inhibiting or facilitating factors in ego development. Participants were 374 adults (aged 18–61; 50 % female) undertaking 11 community leadership development and 2 professional management development programs. After adjusting for effects of age and education, a preference for Intuition on the MBTI was associated with significantly higher ego development on program entry and with greater ego development during the programs. These results are consistent with previous research and provide support for Manners’ and Durkin’s (Developmental Review, 20:475–513, 2000) proposal that dispositional personality characteristics may enhance or constrain ego development.     

A dual-process specification of causal conditional reasoning

There are two accounts describing causal conditional reasoning: the probabilistic and the mental models account. According to the probabilistic account, the tendency to accept a conclusion is related to the probability by which cause and effect covary. According to the mental models account, the tendency to accept a conclusion relates to the availability of counterexamples. These two accounts are brought together in a dual-process theory: It is argued that the probabilistic reasoning process can be considered as a heuristic process whereas the mental models account can be seen as its analytic counterpart. Experiment 1 showed that the two processes differ on a temporal dimension: The variation in fast responses was best predicted by the variation in likelihood information, while the variation in slow responses was best predicted by variation in counterexample information. Experiments 2 and 3 validate the override principle: The likelihood conclusion can be overwritten when specific counterexamples are retrieved in time. In Experiment 2 both accounts were compared based on their difference in input. In Experiment 3 we used a verbal protocol analysis to validate the dual-process idea at the output level. The data of the three experiments provide converging support for framing the two reasoning accounts in a dual-process theory.     

Effects of the brief viewing of emotional stimuli on understanding of insight solutions

In the present study, we examined whether and how brief viewing of positive and negative images influences subsequent understanding of solutions to insight problems. For each trial, participants were first presented with an insight problem and then briefly viewed a task-irrelevant positive, negative, or neutral image (660 ms), which was followed by the solution to the problem. In our behavioral study (Study 1), participants were faster to report that they understood the solutions following positive images, and were slower to report it following negative images. A subsequent fMRI study (Study 2) revealed enhanced activity in the angular gyrus and medial prefrontal cortex (MPFC) while viewing solutions following positive, as compared with negative, images. In addition, greater activation of the angular gyrus was associated with more rapid understanding of the solutions. These results suggest that brief viewing of positive images enhances activity in the angular gyrus and MPFC, which results in facilitation of understanding solutions to insight problems.     

Do Preschoolers Recognize The Emotional Expressiveness of Colors in Realistic and Abstract Art Paintings?

The present study was designed to examine preschoolers' ability to recognize the emotional expressiveness of an art painting, through its colors. To attain this aim 78 children, 3–5 years old were presented with realistic and abstract paintings conveying either happiness or sadness and were asked to choose those which matched the appropriate emotion. In total 16 paintings were used, which varied in color, while their subject matter was held as constant as possible after they had been previously rated by a group of adults to ensure that they conveyed the two emotions under investigation. Results showed that children's ability to recognize the emotional expressiveness of a painting through its colors appears at 3 years old and increases significantly at 4 and 5 years old. It was also found that the mood of happiness was more easily recognized than that of sadness, while the style of art paintings (realistic vs. abstract) did not affect children's ability to recognize emotions.     

A gender role socialization model of explicit and implicit biases in driving self-enhancement

We present a gender role socialization model of explicit and implicit biases in driving self-enhancement. The model proposes that men’s higher levels of driving self-enhancement (relative to women) results from socialization experiences, such as those that idealize driving skill and risk taking as core aspects of male identity. This socialization process produces reasoned explicit (declarative or propositional) associations, but also implicit (automatic, non-conscious) associations between masculinity and driving self-enhancement, and these two processes are theorized to operate relatively independently. Structural Equation Modeling of a large sample of young male (n = 200) and female (n = 200) drivers supported the model, and indicated that (a) gender role identification fully mediated the effect of gender on driving self-enhancement and (b) that this effect occurred simultaneously but relatively independently in both explicit or reasoned belief structures and also in implicit non-conscious associations assessed using the Implicit Association Test. The origins of gender differences in traffic safety behaviour and the implications of our model for shifting conceptions of what it means to be a “real man” with regard to driver behaviour are discussed.     

Reasoning About Uncertain Conditionals

There is a long tradition in formal epistemology and in the psychology of reasoning to investigate indicative conditionals. In psychology, the propositional calculus was taken for granted to be the normative standard of reference. Experimental tasks, evaluation of the participants’ responses and psychological model building, were inspired by the semantics of the material conditional. Recent empirical work on indicative conditionals focuses on uncertainty. Consequently, the normative standard of reference has changed. I argue why neither logic nor standard probability theory provide appropriate rationality norms for uncertain conditionals. I advocate coherence based probability logic as an appropriate framework for investigating uncertain conditionals. Detailed proofs of the probabilistic non-informativeness of a paradox of the material conditional illustrate the approach from a formal point of view. I survey selected data on human reasoning about uncertain conditionals which additionally support the plausibility of the approach from an empirical point of view.
