Beyond arousal and valence: The importance of the biological versus social relevance of emotional stimuli

The present study addressed the hypothesis that emotional stimuli relevant to survival or reproduction (biologically emotional stimuli) automatically affect cognitive processing (e.g., attention, memory), while those relevant to social life (socially emotional stimuli) require elaborative processing to modulate attention and memory. Results of our behavioral studies showed that (1) biologically emotional images hold attention more strongly than do socially emotional images, (2) memory for biologically emotional images was enhanced even with limited cognitive resources, but (3) memory for socially emotional images was enhanced only when people had sufficient cognitive resources at encoding. Neither images’ subjective arousal nor their valence modulated these patterns. A subsequent functional magnetic resonance imaging study revealed that biologically emotional images induced stronger activity in the visual cortex and greater functional connectivity between the amygdala and visual cortex than did socially emotional images. These results suggest that the interconnection between the amygdala and visual cortex supports enhanced attention allocation to biological stimuli. In contrast, socially emotional images evoked greater activity in the medial prefrontal cortex (MPFC) and yielded stronger functional connectivity between the amygdala and MPFC than did biological images. Thus, it appears that emotional processing of social stimuli involves elaborative processing requiring frontal lobe activity.     

Working memory capacity and a notorious brain teaser: the case of the Monty Hall Dilemma

The Monty Hall Dilemma (MHD) is an intriguing example of the discrepancy between people's intuitions and normative reasoning. This study examines whether the notorious difficulty of the MHD is associated with limitations in working memory resources. Experiment 1 and 2 examined the link between MHD reasoning and working memory capacity. Experiment 3 tested the role of working memory experimentally by burdening the executive resources with a secondary task. Results showed that participants who solved the MHD correctly had a significantly higher working memory capacity than erroneous responders. Correct responding also decreased under secondary task load. Findings indicate that working memory capacity plays a key role in overcoming salient intuitions and selecting the correct switching response during MHD reasoning.     

The relevance of selecting what's relevant: A dual process approach to transitive reasoning with spatial relations

The present paper focuses on the heuristic selection process preceding the actual transitive reasoning process. A part of the difficulty of transitive reasoning lies in the selection of the relevant problem aspects. Two experiments are presented using the paradigm introduced by Markovits, Dumas, and Malfait (1995 Markovits, H., Dumas, C. and Malfait, N. 1995. Understanding transitivity of a spatial relationship: A developmental analysis. Journal of Experimental Child Psychology, 59: 124–141.  [Google Scholar]), in which children were asked to make “higher than” inferences about arrays of coloured blocks. In order to discriminate between genuine transitive inference and a simple strategy of relative position, Markovits et al. interspersed white blocks with the coloured blocks, such that the relative position strategy leads to erroneous responses. However, we argue that the white blocks cause confusion due to their ambiguity, which interferes with the heuristic selection process. Two methodological adaptations were introduced, which are hypothesised to facilitate the selection process and improve transitive reasoning: (1) the white blocks were replaced by coloured blocks, and (2) a less abstract context was added to the experimental design. The colour manipulation leads to a clear increase in the use of a transitive strategy by 9-year-old children; 8-year-old children mainly used the relative position strategy. When adding a context story, 9-year-old children used the transitive strategy regardless of the colour of the interspersed blocks. The overall performance of 8-year-olds improved slightly. These results are interpreted as support for a dual-process model of transitive reasoning.     

Necessity and sufficiency in abstract conditional reasoning

The necessity and sufficiency of the cause relates to the conclusions people draw on everyday conditional inference problems. The current research explores the effects of necessity and sufficiency in an abstract causal context. Three experiments showed that the subjective ratings of necessity and sufficiency diverge from the objective levels: A sufficient and necessary cause is more often labelled as sufficient than a sufficient and not-necessary cause. Likewise, a necessary and sufficient cause is more often labelled necessary than a necessary and not-sufficient cause. In Experiments 1 and 2 we observed that the robust effects of sufficiency on MP and MT, and of necessity on AC and DA found on everyday reasoning generalise to abstract conditionals. There were also partial effects of sufficiency on AC and DA, and of necessity on MP and MT. When the problem presentation is simplified, as in Experiment 3, these partial effects on reasoning disappear. The reasoning results then relate to the objective levels and less to the subjective levels of necessity and sufficiency. This divergence sheds doubt on the idea that reasoners base their inferences on an active assessment of the necessity and/or sufficiency of the causal relation.     

Coherence and Nonmonotonicity in Human Reasoning

Nonmonotonic reasoning is often claimed to mimic human common sense reasoning. Only a few studies, though, have investigated this claim empirically. We report four experiments which investigate three rules of SYSTEMP, namely the AND, the LEFT LOGICAL EQUIVALENCE, and the OR rule. The actual inferences of the subjects are compared with the coherent normative upper and lower probability bounds derived from a non-infinitesimal probability semantics of SYSTEM P. We found a relatively good agreement of human reasoning and principles of nonmonotonic reasoning. Contrary to the results reported in the ‘heuristics and biases’ tradition, the subjects committed relatively few upper bound violations (conjunction fallacies).     

Pretending to be authentic: challenges for students when reflective writing about their childhood for assessment

Critical reflection potentially allows social work and human service (SWHS) students to understand how past experiences can shape their future practice. This study of 20 Australian undergraduate SWHS students with a history of childhood adversity found reflective writing for this purpose was not a useful pedagogical practice. Rather than developing skills in critical reflection students found the task performative, linked to academic requirements, where they needed to display emotional containment. Consequently, SWHS academics need to examine reflective writing about childhood adversity for assessment as this process may not enable students to build skills in critical reflection that drive professional development.     

The Climate‐Change Dilemma: Examining the Association Between Parental Status and Political Party Support1

Determining when, and for whom, positive attitudes toward climate‐change actions translate into actual behavior is critically important in promoting pro‐environmental behavior. An important way climate change can be tackled is through changes to social policy at the governmental level, which, in turn, depends on individual voting behavior in democratic nations. The present study examined this issue with regard to political party support in New Zealand, and demonstrated—using a large general population sample of voters—that support for climate‐change actions predict differential support for center‐left and center‐right political parties only for people who have children. Parental status moderated the link between support for climate‐change actions and voting intentions. Practical and theoretical implications of the findings are discussed.     

An Examination of the Actor-Observer Effect in Young Drivers' Attributions for Their Own and Their Friends' Risky Driving

The attributions of 70 young drivers for their own and their friends' risky driving were examined using open-ended questions to determine if there were self-other differences consistent with the actor-observer effect. Six response categories were created, 4 of which were rated as more dispositional than situational by a subsample of the participants and 2 of which were rated as more situational than dispositional. While the largely dispositional category "Showing off, acting cool" was used significantly more for friends than for self, and the largely situational "In a hurry, late" was used significantly more for self than for friends, there was only limited support for the actor-observer effect overall. The participants also rated their friends as taking more risks than themselves. The actor-observer differences are suggested to be influenced primarily by motivational factors and the context in which young people observe their friends' driving. New approaches to traffic safety interventions are suggested.     

The impact of different styles of traffic safety advertisement on young drivers’ explicit and implicit self-enhancement biases

This study examined the immediate psychological impact of positive and negatively framed driving advertisements on (a) deliberative and consciously reported (explicit) and (b) automatic non-conscious (implicit) self-enhancement biases in driving ability and caution (N = 150). Positively framed driving advertisements (those that showed actors modeling safe alternatives to dangerous driving) were most effective at reducing self-enhancement biases in driving ability. This effect was, however, limited to consciously accessible deliberative self-enhancement biases. Exposure to driving advertisements (either positively or negatively framed) did not significantly alter implicit, automatic self-enhancement biases (measured using a computerized reaction-time task). These findings emphasize that positively framed messages are more effective than negatively framed messages at influencing important psychological processes underlying driving behaviour, although such effects are limited, at least in their immediacy, to deliberative fast-learning (or propositional) processes. The implications of these findings for understanding the effects of driving advertisements on the different slow-learning and fast-learning social-cognitive processes underlying self-enhancement biases in young drivers’ self-perceptions, and hence driver behaviour, are discussed.
